1705 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1706 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3901 (Build_Discriminated_Subtype): Do not inherit representation clauses
3902 from parent type if subtype already carries them, because they are
3903 inherited earlier during derivation and already include those that may
3904 come from a partial view.

3942 operation of an RACW stub type (these primitives are only executed
3943 through dispatching, never through static calls).
3944 (Collect_Interps): When only one interpretation has been found, set N's
3945 Entity and Etype to that interpretation, otherwise Entity and Etype may
3946 still refer to an interpretation that was ignored by Add_One_Interp,
3947 in which case would end up with being marked as not overloaded but with
3948 an Entity attribute not pointing to its (unique) correct interpretation.

8207 subprogram body that acts as its own spec may not have a non-private
8208 WITH clause on a private sibling.
8209 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8210 child unit is a renaming, create an implicit with_clause on that
8211 parent, and not on the unit it renames, to prevent visibility errors

8258 of Related_Interface to Related_Type.
8259 (Record_Type_Declaration): Minor reordering of calls to decorate the

8278 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8279 type from a limited_with_clause, and the full view is available, use it

8308 Gary Dismukes <dismukes@adacore.com>
8310 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8311 requeue statement is dispatching. Do not emit an error when the name is

8315 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8316 Timed_Entry_Call): Analyze the triggering statement as the first step of
8317 the processing. If this is a dispatching select, postpone the analysis
8318 of all select statements until the Expander transforms the select. This
8319 approach avoids generating duplicate identifiers after the Expander has
8320 replicated some of the select statements. In case the Expander is
8321 disabled, perform regular analysis.
8322 (Check_Triggering_Statement): New routine.
8323 (Analyze_Requeue): Exclude any interpretations that are not entries when
8324 checking overloaded names in a requeue. Also test type conformance for

8333 for the defaulted actual.
8335 2007-12-13 Geert Bosch <bosch@adacore.com>
8337 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8893 Add Unreferenced and Warnings (Off) pragmas for cases of
8894 variables modified calls where they are IN OUT or OUT parameters and
8895 the resulting values are not subsequently referenced. In a few cases,
8896 we also remove redundant code found by the new warnings.

8914 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
8916 (Xref_Record): Change type for Line, since in the case of a reference to
8917 a predefined entity (as happens for array index types), the line is set
8919 Add support for parsing multiple array index types info, or
8920 multiple inherited interfaces info. This information cannot be stored
8921 in Xref_Entity_Record, which only supports a single instance of Tref_*,
8922 and is therefore stored in the list of references instead. It has a
8923 special treatement later on in tools that use this information.
8925 2007-10-15 Tristan Gingold <gingold@adacore.com>
8927 * debug.adb: Document use of -gnatd.a and -gnatd.I
8929 * layout.adb: On OpenVMS -gnatd.a disables alignment optimization.

8933 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
8934 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
8935 care of access to class-wide interface types plus removal of bizarre
8936 conversion of tagged object to access type (reported by Gary
8937 Dismukes). After this patch there is no need to perform any
8938 additional management on these nodes in Expand_Interface_Actuals.
8940 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8941 that handles use of 'Access and 'Unchecked_Access applied to
8942 actuals covering interface types. Such code is now
8943 centralized in Expand_N_Attribute_Reference.
8945 2007-10-15 Ed Schonberg <schonberg@adacore.com>
8947 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
8948 of tagged types whose ultimate ancestor is a CPP type.
8949 (Freeze_Array_Type): For a packed array type, generate an initialization
8950 procedure if the type is public, to handle properly a client that
8951 specifies Normalize_Scalars.
8953 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8955 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

8973 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
8974 the generic Heap_Sort_G, in order to avoid trampolines.

8979 * vx_stack_info.c: New file.
8981 * i-forbla-unimplemented.ads: New file.
8983 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
8984 for unsupported configurations; use it on VMS targets instead of the
8986 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
8987 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
8988 used by VxWorks targets to have access to task-specific data and be
8989 able to extract the stack boundaries for stack checking.
8990 Use system-vms-ia64.ads on ivms.
8992 * Make-lang.in: Update dependencies.
8994 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

9011 95 reserved word in its name.
9012 (Process_Project_Level_Array_Attributes): Process new attribute
9013 Runtime_Library_Dir.
9015 * prj-part.adb (Parse_Single_Project): Do not check the name of the

9031 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9033 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9034 association for an access component, add an association with null as
9035 the expression. Remove testing for array subtypes and the setting in
9036 that case of Ctyp to the array component type, which prevented proper
9037 inclusion of an association for null-initialized arrays. Collapse
9038 condition that tests for array subtypes into just a test of
9039 Is_Partially_Initialized_Type (which already covers arrays anyway).
9041 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9043 * sem_ch12.adb: Minor code reformatting.
9044 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to
9045 find the parent package which may have been hidden by local
9048 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9050 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9051 flag of derived concurrent types, taking into account the flag setting
9052 on the parent subtype and any new set of discriminants.
9054 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9056 * sem_ch4.adb: Minor code and comment reformatting.
9057 (Analyze_Allocator): When the designated type of an unconstrained
9058 allocator is a record with unknown discriminants or an array with
9059 unknown range bounds, emit a detailed error message depending on the
9060 compilation mode and whether the designated type is limited.

9115 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
9116 gnatxref, gnatfind, gnatls, and gnatclean.

9135 to generate g-soccon-vms.ads.
9137 * atree.adb: Add ??? comment

9193 type of file_info_ptr parameter.
9194 If mapped location support is enabled, create the isomorphic mapping
9195 between source files and line maps.
9196 (Sloc_to_locus): If mapped location support is enabled, translate
9197 source location into mapped location.
9198 (annotate_with_node): Rename into set_expr_location_from_node.

9224 * a-calend-vms.adb, a-calend.adb:
9225 Add a section on leap seconds control along with two entities used to
9226 enable and disable leap seconds support. The array Leap_Second_Times is
9227 now constant and contains hard time values pre-generated. Remove
9228 all elaboration code used to populate the table of leap seconds.
9231 Add entity Leap_Seconds_Support to the list of global run-time variables
9232 along with a comment on its usage and values.
9233 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9289 Eric Botcazou <ebotcazou@adacore.com>
9292 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9293 indirection added to the HT_Link component of the TSD. This is required
9294 to statically allocate the TSD.
9297 Minor reordering of the declarations in the private part. Required to
9298 add a level of indirection to the contents of the TSD component HT_Link.

9313 purpose Make_DT now declares a separate object that stores the
9314 HT_Link value, and initializes the TSD component with the address
9315 of this new object. The addition of this level of indirection is
9316 required to statically allocate the TSD because the TSD cannot
9317 have variable components.
9318 (Expand_Interface_Conversion): Improve the expanded code.
9319 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9321 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9322 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9323 if we are building static dispatch tables then we must not generate
9324 extra code to register the primitive because the dispatch table will
9325 be built at the end of the library package; otherwise we notify that
9326 we cannot build the static dispatch table.

9349 associated with interface types.
9350 Extensive comment fixes regarding flags that appear in all entities. The
9351 documentation is now consistent for all such flags (there were a number
9352 of errors in the documentation in this regard).
9354 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9356 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9357 of these procedures are passed a function call that already has
9358 build-in-place actuals (testing new flag
9359 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9360 the case where processing continues.
9361 (Expand_Call): If the call is generated from a thunk body then we
9362 propagate the extra actuals associated with the accessibility
9363 level of the access type actuals.
9365 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9366 of each extra formal of a protected operation to reference the
9367 corresponding extra formal of the subprogram denoted by the
9368 operation's Protected_Body_Subprogram.
9370 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9371 N_Function_Call nodes.
9373 2007-09-26 Robert Dewar <dewar@adacore.com>
9375 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set

9382 debug variable so that it won't be initialized when pragma
9383 Initialize_Scalars is in effect.
9385 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9387 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9388 initialization of a full view. This is moved to

9392 preelaborable initialization of a full view in entity loop.
9393 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9394 its child units are use-visible only if they are visible child units.
9396 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9397 whether an expression can be used within a type declaration that
9398 requires preelaborable init.
9399 (Check_Components): Replace inline code that does partial checking for
9400 preelaborable default expressions with call to
9401 Is_Preelaborable_Expression.
9402 (Has_Preelaborable_Initialization): In the case of a generic actual
9403 subtype, (that is, Is_Generic_Actual is True), return the result of
9404 applying Has_Preelaborable_Initialization to the generic actual's base
9407 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9409 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9410 call to Jan_1_Day _Of_Week to optimize its performance.
9411 (Is_Leap): Move the routine to the scope of Week_In_Year.
9412 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9413 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9414 avoids calling Time_Of and Split, thus making it more efficent.
9415 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9417 * g-calend.ads (Week_In_Year): Change comment to reflect new
9420 2007-09-26 Emmanuel Briot <briot@adacore.com>
9422 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9423 Command_Line): New types
9424 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9425 support for defining how switches can be grouped on a command line (as
9426 is the case for -gnatw... for GNAT), and how simple switches can be
9427 used as aliases for more complex switches (-gnatwa is same as
9429 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9430 (Start, Current_*): New subprograms
9431 Added support for parsing an array of strings in addition to the real
9433 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9434 be moved from the body to the private part of the spec.
9435 (*): All subprograms now have an extra parameter with default value to
9436 specify which parser should be used. For backward compatibility, it
9437 defaults to parsing the command line of the application. They were also
9438 modified to properly handle cases where each of the argument does not
9439 start at index 1 (which is always true for Ada.Command_Line, but not
9440 when processing any Argument_List).
9441 (Free): New subprogram
9442 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9443 Argument): New subprograms
9444 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9445 special characters like ':', '=',... are now handled in a single place,
9446 which makes the code more extensible eventually.
9447 (Getopt, Full_Switch): When the switch was returned as part of the
9448 special character '*', make sure it is prepended by the switch character
9449 ('-' in general), so that the application knows whether "foo" or "-foo"
9450 was specified on the command line.
9452 2007-09-26 Florian Villoing <villoing@adacore.com>
9454 * g-dirope.adb (Remove_Dir): In case we are removing directories
9455 recursively, make sure that if an exception is raised during the
9456 processing, the current working directory is reset to its initial
9457 value before propagating the exception.
9459 2007-09-26 Vincent Celier <celier@adacore.com>
9461 * gnatbind.adb: If there are several ALI files specified and there is
9462 a main program to bind, the first ALI is expected to contain the main
9463 subprogram and the names of the binder generated files will be derived
9464 from the first ALI file name.
9465 (Gnatbind): Fix insertion character in invocation of Error_Msg
9467 2007-09-26 Vincent Celier <celier@adacore.com>
9469 * gnatcmd.adb (Check_Files): Do not include sources that have been
9470 removed by attributes Exclude_Source_Files or Locally_Removed_Files.

9475 information about each of its index types, following the type
9476 reference for its component type.
9478 2007-09-26 Vincent Celier <celier@adacore.com>
9480 * make.adb: (Kill): New procedure (__gnat_kill imported)

9484 compilation processes.
9486 (Gnatmake): If project files are used, create the mapping of all the
9487 sources, so that the correct paths will be found.

9493 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9495 * prj.ads, prj.adb (Default_Language): Remove function, no longer used

9502 * prj-attr.adb: New attributes Required_Switches (<language>) in
9503 packages Compiler and Binder.
9505 * prj-nmsc.adb: Major rewrite of the processing of configuration
9506 attributes for gprbuild. No impact on GNAT tools.
9508 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9509 process configuration attributes: this is done in Prj.Nmsc.Check.
9510 (Recursive_Process): Make a full copy of packages inherited from project
9511 being extended, instead of a shallow copy.
9512 (Process_Project_Tree_Phase_1): New procedure
9513 (Process_Project_Tree_Phase_1): New procedure
9514 (Process): Implementation now uses the two new procedures
9516 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9517 from the project config, not the tree config that no longer exists.

9543 ancestor of the derived type, the operations are inherited from the
9544 primary dispatch table of the parent.
9545 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9546 when the context is an explicit type conversion.

9843 Thomas Quinot <quinot@adacore.com>
9845 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9846 create an abstract subprogram in the case of 'Input. For 'Output we now
9847 create a real spec/body when the type is abstract, since it can
9848 potentially be called.
9849 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9850 body for 'Output when the type is abstract (only the creation of the
9851 body for 'Input is excluded when the type is abstract).
9852 (Stream_Operation_OK): Add an additional condition in the return
9853 statement, so that False will be returned for TTS_Stream_Input if the
9854 associated tagged type is an abstract extension. Add comments for
9856 (Expand_N_Object_Declaration): For the case of a shared passive
9857 variable, insert init proc call only after the shared variable
9858 procedures have been processed, because the IP call needs to undergo
9859 shared passive variable reference expansion, which requires these
9860 procedures to be available (and elaborated).
9862 2007-09-10 Vincent Celier <celier@adacore.com>
9864 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove

9867 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9869 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
9870 given a box association, the type of the component is discriminated,
9871 and the value of the discriminant is the discriminant of the enclosing
9872 type, retrieve its value from the aggregate itself, where it must have
9875 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9876 to remove other spurious ambiguities on arithmetic operations involving
9877 literals and addresses, on systems where Address is a visible integer
9878 type, when the operator is called in functional notation.
9879 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9880 is legal when the types match, even if the operation is currently
9883 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9885 * sem_ch12.adb (Build_Local_Package): A formal package with no
9886 associations is legal if all formals have defaults. It is not
9887 equivalent to a formal declared with a box.

9998 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10000 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10005 (Write_Entity_Flags): Write the status of flag Is_Raised.
10006 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10007 spurious ambiguities when integer literals appear in the context of an
10008 address type that is a visible integer type.
10010 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10011 exceptions never being raised.
10012 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10015 2007-08-31 Javier Miranda <miranda@adacore.com>
10017 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise
10018 statement when compiling under restriction No_Exceptions_Proparation.

10022 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
10023 initialization aggregate for the type, generate itype references for
10024 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
10026 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10028 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10029 library-level package renaming, pass the declaration associated with
10030 the renaming's special debug variable to Qualify_Entity_Names to ensure
10031 that its encoded name is properly qualified.
10033 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10034 occurring in the list of entities to qualify, and do not attempt to
10035 traverse an entity list in that case. Variables associated with
10036 ` library-level package renamings can now occur in the table.
10038 * exp_dbug.ads: Revise documentation of the encoding for renaming
10041 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10044 access type points to an unconstrained array.
10046 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10048 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10051 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
10052 simple redundant qualifications. The check is performed whenever the
10053 expression is a non-overloaded identifier.
10054 (Resolve_Type_Conversion): Enchance the redundant type conversion check
10055 to include loop parameters.
10056 (Valid_Conversion): Avoid generation of spurious error message.

10060 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10061 concatenations of string literals into a single literal, in order to
10062 avoid very deep recursion in the front end, which was causing stack
10065 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10066 string, and the right operand is a string literal (the case of "" &
10067 "..."), optimize by avoiding copying the right operand -- just use the
10068 value of the right operand directly.
10070 * stringt.adb (Store_String_Chars): Optimize by growing the
10071 String_Chars table all at once, rather than appending characters one by
10073 (Write_String_Table_Entry): If the string to be printed is very long,
10074 just print the first few characters, followed by the length. Otherwise,
10075 doing "pn(n)" in the debugger can take an extremely long time.
10077 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10078 Store_String_Char with Store_String_Chars.
10080 2007-08-31 Vincent Celier <celier@adacore.com>

10095 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10097 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10098 flag, for effiency. It is called when analyzing arithmetic operators
10099 and also for actuals in calls that are universal_integers. The flag is
10100 set for the predefined type address, and for any type or subtype
10103 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10104 Universal_Integer, when the formal is a descendent of address and the
10105 call appears in user code.
10106 (Analyze_Selected_Component): if the prefix is a private extension, the
10107 tag component is visible.

10170 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10172 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10173 associated with Standard_Debug_Renaming_Type, to be used as the type of
10174 the special variables whose names provide debugger encodings for
10175 renaming declarations.
10177 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10178 (Set_Debug_Renaming_Link): Change to set Node25.

10181 "Debug_Renaming_Link".
10182 (Write_Field23_Name): Correct the output string for "Limited_View".
10184 * exp_dbug.adb: Add with and use of Tbuild.
10185 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10186 and literal with creation of a variable of type
10187 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10188 and the entity of the renaming declaration.
10189 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10190 part of the name of a variable that has a Debug_Renaming_Link.
10192 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10193 special type to be associated with variables that provide debugger
10194 encodings for renaming declarations.

10197 Ed Schonberg <schonberg@adacore.com>
10198 Javier Miranda <miranda@adacore.com>
10200 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10201 ancestor part given by an aggregate to test for an unchecked conversion,
10202 since this can occur in some cases when the ancestor part is a function
10203 call, and we don't want to fall into the recursive call to this
10204 procedure in that case.
10206 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10207 stream attributes on limited types to account for user-specified
10208 attributes as well as whether Input (resp. Output) becomes available
10209 due to Read (resp. Write) being available for the type. Change Boolean
10210 variable to the more accurate name
10211 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10212 double-"not" predicate at beginning of return statement to more
10213 understandable form.
10215 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10216 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10217 in a block statement and use that as the first statement of the
10218 expanded return rather than incorrectly using the handled sequence as
10219 the first statement.
10221 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10222 operation, generate an explicit freeze node for it rather than
10223 generating extra formals, to ensure that gigi has the proper order of
10224 elaboration for anonymous subtypes in the signature of the subprograms.
10225 (Build_In_Place_Formal): Move assertion to beginning of loop.
10226 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10227 applied to a function call (occurs for some cases of 'Input).
10228 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10229 applied to a function call (occurs for some cases of 'Input).
10231 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10232 2005, generate an extended return statement enclosing the result object
10235 * freeze.adb (Freeze_Record_Type): Extend the current management of
10236 components that are access type with an allocator as default value: add
10237 missing support to the use of qualified expressions of the
10238 allocator (which also cause freezing of the designated type!)
10239 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10240 dispatching operation, since extra formals may be needed by calls to
10241 build-in-place functions (such as stream 'Input).
10243 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10244 formals for 'Constrained and accessibility level in the case of a
10245 predefined dispatching operation.
10247 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10248 point, no need to find the parent node.
10250 2007-08-16 Javier Miranda <miranda@adacore.com>
10252 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10253 and entry barriers.
10255 2007-08-16 Javier Miranda <miranda@adacore.com>
10257 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10258 is not really required and can introduce regression with the debugger.
10259 The original problem is fixed with the patch written for checks.adb.
10261 2007-08-16 Thomas Quinot <quinot@adacore.com>
10263 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10264 Range_Check on Allocated_Table.

10269 Including_Non_Switch set to False.
10270 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10271 Including_Non_Switch set to False.
10273 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10274 parameter Including_Non_Switch, defaulted to True. When
10275 Including_Non_Switch is False, options that are not switches and
10276 appear as relative path are not converted to absolute paths.
10278 2007-08-16 Nicolas Roche <roche@adacore.com>
10280 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
10283 * Make-lang.in: Update dependencies

10287 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10288 currently inspected is a selected component, retrieve the entity of
10290 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10291 from the immediate ancestor of Main_Unit_Entity.
10292 (Install_Limited_Withed_Unit): Do not install the limited view of
10293 package P if P is reachable through an ancestor chain from package C
10294 and C also has a with clause for P in its body.
10295 (Has_Limited_With_Clause): New routine.
10296 (Has_With_Clause): New routine.
10298 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10300 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the

10328 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10329 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10330 the statement which is being resolved comes from a predefined library
10331 unit, all non-predefined library interpretations are skipped.
10332 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10333 but the "&" is user defined, give an error, because the folding would

10337 the parser has folded a long sequence of concatenations of string
10340 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10341 and "JMP_BUF" variables as artificial.
10342 (N_String_Literal): Do not use alloca for very long string literals. Use
10343 xmalloc/free instead. Otherwise the stack might overflow.
10345 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the

10390 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10391 Suppress unmodified in-out parameter warning in some cases
10392 This patch is a also fairly significant change to the way suppressible
10393 checks are handled.
10395 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10396 needed for access to concurrent record types generated by the expander.
10397 (Generate_Range_Check): When generating a temporary to capture the
10398 value of a conversion that requires a range check, set the type of the
10399 temporary before rewriting the node, so that the type is always
10400 properly placed for back-end use.
10401 (Apply_Float_Conversion_Check): Handle case where the conversion is
10403 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10404 for a protected type in order to examine its discriminants.

10411 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10412 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10413 tests optimized out.
10415 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10416 (Get_Allocator_Final_List): For the case of an anonymous access type
10417 that has a specified Associated_Final_Chain, do not go up to the
10419 (Expand_N_Type_Conversion): Test for the case of renamings of access
10420 parameters when deciding whether to apply a run-time accessibility
10422 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10423 aggregate code before allocator, and ahead of declaration for
10424 temporary, to prevent access before elaboration when the allocator is
10425 an actual for an access parameter.
10426 (Expand_N_Type_Conversion): On an access type conversion involving an
10427 access parameter, do not apply an accessibility check when the
10428 operand's original node was an attribute other than 'Access. We now
10429 create access conversions for the expansion of 'Unchecked_Access and
10430 'Unrestricted_Access in certain cases and clearly accessibility should
10431 not be checked for those.
10433 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10434 includes a type conversion of a packed component that has been expanded,
10435 recover the original expression for the object, and use this expression
10436 in the post-call assignment statement, so that the assignment is made
10437 to the object and not to a back-end temporary.
10438 (Freeze_Subprogram): In case of primitives of tagged types not defined
10439 at the library level force generation of code to register the primitive
10440 in the dispatch table. In addition some code reorganization has been
10441 done to leave the implementation clear.
10442 (Expand_Call): When expanding an inherited implicit conversion,
10443 preserve the type of the inherited function after the intrinsic
10444 operation has been expanded.
10446 * exp_ch2.ads, exp_ch2.adb
10447 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10448 of an entry formal appearing in an assignment statement does not assign
10450 (Expand_Current_Value): Instead of calling a routine to determine
10451 whether the prefix of an attribute reference should be optimized or
10452 not, prevent the optimization of such prefixes all together.
10454 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10455 component whose prefix is known to be of an access type is an implicit
10456 dereference and does not assign to the prefix.
10458 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10459 Robert Dewar <dewar@adacore.com>
10461 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10462 itype is visited, make an entry into table to link associated node and
10464 Add comments and correct harmless error in Build_NCT_Hash_Tables
10465 (Array_Aggr_Subtype): Associate each itype created for an index type to
10466 the corresponding range construct, and not to the aggregate itself. to
10467 maintain a one-to-one correspondence between itype and its associated
10468 node, to prevent errors when complex expression is copied.
10469 Fix mishandling of multiple levels of parens
10471 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10472 treatment of limited views uniform for all visible declarations in a
10473 limited_withed package.
10474 (New_Copy_Tree): If hash table is being used and itype is visited,
10475 make an entry into table to link associated node and new itype.
10476 (Resolve_Record_Aggregate): Do not add an others box association for a
10477 discriminated record component that has only discriminants, when there
10478 is a box association for the component itself.
10480 * par-ch4.adb: Fix mishandling of multiple levels of parens
10482 2007-08-14 Robert Dewar <dewar@adacore.com>

10518 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10519 to make treatment of limited views uniform for all visible declarations
10520 in a limited_withed package.
10521 Improve warnings for in out parameters
10522 (Set_Related_Interaface/Related_Interface): Allow the use of this
10523 attribute with constants.
10524 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10525 Warn on duplicate pragma Preelaborable_Initialialization
10527 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10528 generation of a freezing node to ensure proper management of null
10529 excluding access types in the backend.
10530 (Create_Extra_Formals): Test base type of the formal when checking for
10531 the need to add an extra accessibility-level formal. Pass the entity E
10532 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10533 originally being done in a couple of cases), to ensure that the
10534 Extra_Formals list gets set on the entity E when the first entity is
10536 (Conforming_Types): Add missing calls to Base_Type to the code that
10537 handles anonymous access types. This is required to handle the
10538 general case because Process_Formals builds internal subtype entities
10539 to handle null-excluding access types.
10540 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10541 functions that need it, even when not marked Requires_Overriding.
10542 Improve warnings for in out parameters
10543 (Analyze_Function_Return): Warn for disallowed null return
10544 Warn on return from procedure with unset out parameter
10545 Ensure consistent use of # in error messages
10546 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10547 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10548 the implicit conversion of the expression done for anonymous access
10549 types. This is required to generate the code of the null excluding
10550 check (if required).
10552 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10553 A formal parameter is never publicly referenceable outside of its body.
10554 (Check_References): For an unreferenced formal parameter in an accept
10555 statement, use the same warning circuitry as for subprogram formal
10557 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10558 Output_Unreferenced_Messages, containing the part of that routine that
10559 is now reused for entry formals as described above.
10560 (Goto_Spec_Entity): New function
10561 (Check_References): Do not give IN OUT warning for dispatching operation
10562 Improve warnings for in out parameters

10570 Gary Dismukes <dismukes@adacore.com>
10572 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10573 (Expand_N_Attribute_Reference): Further unify the handling of the
10574 three forms of access attributes, using common code now for all three
10575 cases. Add a test for the case of applying an access attribute to
10576 an explicit dereference when the context is an access-to-interface
10577 type. In that case we need to apply the conversion to the prefix
10578 of the explicit dereference rather than the prefix of the attribute.
10579 (Attribute_Version, UET_Address): Set entity as internal to ensure
10580 proper dg output of implicit importation.
10581 (Expand_Access_To_Type): Removed.
10582 (Expand_N_Attribute_Reference): Merge the code from the three cases
10583 of access attributes, since the processing is largely identical for
10584 these cases. The substantive fix here is to process the case of a
10585 type name prefix (current instance case) before handling the case
10586 of interface prefixes.

10591 Robert Dewar <dewar@adacore.com>
10593 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10594 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10595 type that is an anonymous access to controlled object, establish
10596 an associated finalization chain to avoid corrupting the global
10597 finalization list when a dynamically allocated object designated
10598 by such a component is deallocated.
10599 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10600 functions that need it, even when not marked Requires_Overriding.
10601 (Initialize_Tag): Replace call to has_discriminants by call to
10602 Is_Variable_Size_Record in the circuitry that handles the
10603 initialization of secondary tags.
10604 (Is_Variable_Size_Record): New implementation.
10605 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10606 Suppress_Initialization pragma for a derived type.
10607 (Is_Variable_Size_Record): New subprogram.
10608 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10609 initial version of this routine and also fixes problems causing
10610 incomplete initialization of the table of interfaces.
10611 (Build_Init_Procedure): Improve the generation of code to initialize the
10612 the tag components of secondary dispatch tables.
10613 (Init_Secondary_Tags): New implementation that simplifies the previous
10614 version of this routine.
10615 (Make_DT): Add parameter to indicate when type has been frozen by an
10616 object declaration, for diagnostic purposes.
10617 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10618 diagnose attemps to freeze a subprogram when some untagged type of its
10619 profile is a private type whose full view has not been analyzed yet.
10620 (Freeze_Array_Type): Generate init proc for packed array if either
10621 Initialize or Normalize_Scalars is set.
10622 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10623 constructing the new profile, copy the null_exclusion indicator for each
10624 parameter, to ensure full conformance of the new body with the spec.
10626 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10627 Create wrappers for constructor functions that need it, even when not
10628 marked Requires_Overriding.
10629 (Covers): Handle properly designated types of anonymous access types,
10630 whose non-limited views are themselves incomplete types.
10631 (Add_Entry): Use an entity to store the abstract operation which hides
10633 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10634 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10635 initialization aggregate.
10636 (Function_Interp_May_Be_Hidden): Rename to
10637 Function_Interp_Has_Abstract_Op.
10638 (Has_Compatible_Type): Remove machinery that skips interpretations if
10639 they are labeled as potentially hidden by an abstract operator.
10640 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10641 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10642 (Write_Overloads): Output the abstract operator if present.
10643 (Add_Entry): Before inserting a new entry into the interpretation table
10644 for a node, determine whether the entry will be disabled by an abstract
10646 (Binary_Op_Interp_May_Be_Hidden): New routine.
10647 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10649 (Function_Interp_May_Be_Hidden): New routine.
10650 (Has_Compatible_Type): Do not consider interpretations hidden by
10651 abstract operators when trying to determine whether two types are
10653 (Has_Hidden_Interp): New routine.
10654 (Set_May_Be_Hidden_Interp): New routine.
10655 (Write_Overloads): Write the status of flag May_Be_Hidden.

10660 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10661 types declared in the declarative part of a nested package body or in
10662 the proper body of a stub.
10663 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10664 of the same dispatch table slot to renamed primitives.
10665 (Make_Select_Specific_Data_Table): Handle private types.
10666 (Tagged_Kind): Handle private types.
10667 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10668 output of implicit importation and exportation.
10669 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10670 first formal of the thunk is always associated with the controlling
10671 type. In addition perform the following code cleanup: remove formal
10672 Thunk_Alias which is no longer required, cleanup evaluation of the
10673 the controlling type, and update the documentation.
10674 Replace occurrence of Default_Prim_Op_Count by
10675 Max_Predef_Prims. Addition of compile-time check to verify
10676 that the value of Max_Predef_Prims is correct.
10677 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10678 (Make_DT): Add parameter to indicate when type has been frozen by an
10679 object declaration, for diagnostic purposes.
10680 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10681 construction of statically allocated dispatch tables.
10682 (Make_DT): In case of library-level tagged types export the declaration
10683 of the primary tag. Remove generation of tags (now done by Make_Tags).
10684 Additional modifications to handle non-static generation of dispatch
10685 tables. Take care of building tables for asynchronous interface types
10686 (Make_Tags): New subprogram that generates the entities associated with
10687 the primary and secondary tags of Typ and fills the contents of Access_
10688 Disp_Table. In case of library-level tagged types imports the forward
10689 declaration of the primary tag that will be declared later by Make_DT.
10690 (Expand_Interface_Conversion): In case of access types to interfaces
10691 replace an itype declaration by an explicit type declaration to avoid
10692 problems associated with the scope of such itype in transient blocks.

10695 Ed Schonberg <schonberg@adacore.com>
10696 Javier Miranda <miranda@adacore.com>
10698 * exp_util.ads, exp_util.adb:
10699 This patch replaces a number of occurrences of explicit tests for N_Null
10700 with calls to Known_Null. This improves tracking of null values, since
10701 Known_Null also catches null constants, and variables currently known to
10702 be null, so we get better tracking.
10703 (Ensure_Defined): create an itype reference only in the scope of the
10705 (Side_Effect_Free): A selected component of an access type that
10706 denotes a component with a rep clause must be treated as not
10707 side-effect free, because if it is part of a linked structure its
10708 value may be affected by a renaming.
10709 (Expand_Subtype_From_Expr): For limited objects initialized with build
10710 in place function calls, do nothing; otherwise we prematurely introduce
10711 an N_Reference node in the expression initializing the object, which
10712 breaks the circuitry that detects and adds the additional arguments to
10713 the called function. Bug found working in the new patch for statically
10714 allocated dispatch tables.
10715 (Is_Library_Level_Tagged_Type): New subprogram.
10716 (Remove_Side_Effects): If the expression of an elementary type is an
10717 operator treat as a function call.
10718 (Make_Literal_Range): If the index type of the array is not integer, use
10719 attributes properly to compute the constraint on the resulting aggregate
10722 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10723 class-wide type whose base type is an incomplete private type, leave
10724 class-wide type unfrozen so that freeze nodes can be generated
10725 properly at a later point.
10726 (Freeze_Entity, array case): Handle case of pragma Pack and component
10727 size attributre clause for same array.
10729 2007-08-14 Vincent Celier <celier@adacore.com>

10734 (Reset): Initialize all tables and hash tables in the project tree data
10735 Major update of the Project Manager and of the project aware tools,

10737 can be used by gprbuild.
10738 (Slash_Id): Change type to be Path_Name_Type
10739 (Slash): Return a Path_Name_Type instead of a File_Name_Type

10751 including gprmake, so that the same sources in the GNAT repository
10752 can be used by gprbuild.
10754 * prj-dect.adb (Prj.Strt.Attribute_Reference): Set correctly the case
10755 insensitive flag for attributes with optional index.
10756 (Prj.Dect.Parse_Attribute_Declaration): For case insensitive associative
10757 array attribute, put the index in lower case.
10758 Update Project Manager to new attribute names for ghprbuild
10759 Allow all valid declarations in configuration project files

11355 (Set_Item): When the new item is an element of the currently allocated
11356 table passed by reference, save a copy on the stack if we're going
11357 to reallocate. Also, in Table.Set_Item, make sure we test the proper

11373 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11374 derived type with interface progenitors use the analyzed formal as the
11375 parent of the actual, to create renamings for all the inherited
11376 operations in Derive_Subprograms.
11377 (Collect_Previous_Instances): new procedure within of
11378 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11379 unit being loaded, to ensure that the generation of global symbols is
11380 consistent in different compilation modes.
11381 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11382 takes progenitor types into account.
11383 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11384 traversing over the primitives of the formal and actual types to locate
11385 any abstract subprograms of the actual type that correspond to a
11386 nonabstract subprogram of the formal type's ancestor type(s), and issue
11387 an error if such is found.
11388 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11389 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11390 Remove bogus guard around calls to Inherit_Context.
11391 (Reset_Entity): If the entity is the selector of a selected component
11392 that denotes a named number, propagate constant-folding to the generic
11393 template only if the named number is global to the generic unit.
11394 (Set_Instance_Env): Only reset the compilation switches when compiling
11395 a predefined or internal unit.
11397 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11399 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11400 parameter to determine whether operation applies to the prefix.
11401 (Complete_Object_Operation): If actual has an access type and
11402 controlling formal is not an in_parameter, reject the actual if it is
11403 an access_to_constant type.
11404 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11405 type, the candidate operations are found in the scope of declaration of
11406 the type, because the type has no primitive subprograms.
11407 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11408 a private extension, only examine visible components before trying to
11409 analyze as a prefixed call.
11410 Change Entity_List to Type_To_Use, for better readability.
11411 (Has_Fixed_Op): Use base type when checking whether the type of an
11412 operator has a user-defined multiplication/division
11413 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11414 user-defined operators are available for fixed-point types.

11419 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11420 formal At_Any_Place indicating, when True, that we want to test for
11421 availability of the stream attribute at any place (as opposed to the
11422 current visibility context only).
11423 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11424 purpose of enforcing E.2.2(8) only if it is not available at any place.
11425 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11426 when checking the legality of an extension aggregate in a preelaborable
11427 package. Treat the literal null as a valid default expression in a
11428 component declaration for a type with preelaborable initialization.
11429 A limited interface is a legal progenitor for the designated type of a
11430 remote access to class-wide type.

11439 setting the Referenced_As_LHS flag for entities that are implicitly
11441 (Find_Type): If the type is an internally generated incomplete type,
11442 mark the full view as referenced, to prevent spurious warnings.
11443 (Find_Selected_Component, Has_Components): Handle properly non-limited
11444 views that are themselves incomplete types.
11445 Handle interfaces visible through limited-with clauses.
11446 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11447 subprogram generic actual for which we have generated a renaming.
11448 Warn when the renaming introduces a homonym of
11449 the renamed entity, and the renamed entity is directly visible.

11455 appear in the subtree to the current allocator if it is not a static
11457 (Resolve_Allocator): Perform cleanup if resolution has determined that
11458 the allocator is not a coextension.
11459 (Resolve): Skip an interpretation hidden by an abstract operator only
11460 when the type of the interpretation matches that of the context.
11461 (Resolve): When looping through all possible interpretations of a node,
11462 do not consider those that are hidden by abstract operators.
11463 (Resolve_Actuals): When verifying that an access to class-wide object
11464 is an actual for a controlling formal, ignore anonymous access to
11465 subprograms whose return type is an access to class_wide type.
11466 (Resolve_Slice): If the prefix of the slice is a selected component
11467 whose type depends on discriminants, build its actual subtype before
11468 applying range checks on the bounds of the slice.
11469 (Valid_Conversion): In an instance or inlined body, compare root types,
11470 to prevent anomalies between private and public views.
11471 (Resolve): Improve error message for ambiguous fixed multiplication
11472 expressions that involve universal_fixed multiplying operations.

11489 typecode parameters for a union (in a variant record), remove
11490 extraneous layer of Any wrapping for member label.
11491 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
11492 elabration statements, register the package with the name server
11493 at the beginning, not at the end, of the elaboration statements so
11494 that they can create remote access to subprogram values that designate
11495 remote subprograms from the package.
11497 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
11499 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
11500 values to compute the number of seconds since the Unix Epoc in order to

11690 than propagating the From_Limited_With flag, in order to handle
11691 properly circularities involving with_clauses.

12549 (build_call_alloc_dealloc): When releasing a super-aligned object,
12550 retrieve the system's allocator return value from where build_allocator

12578 (Gen_Output_File_Ada, Gen_Output_File_C): Never use __attribute
12579 ((destructor)) for adafinal, even when switch -a is used.
12580 Do not issue pragma Linker_Destructor for adafinal when switch -a is
12582 (Gen_Object_Files_Options): Add formatting of Linker Options, when
12583 Output_Linker_Option_List is set. Suppress this formatting when
12584 Zero_Formatting is set.
12585 Add case for CLI_Target.
12586 (System_Restrictions_Used): New flag, used to avoid generating with of
12587 System_Restrictions and initialization of the data unless there is
12588 some use of System.Restrictions in the partition.

12620 Code clean up: remove obsolete code related to GCC 2.
12621 (Get_E_Length): Protect against bomb in case scope is standard
12622 (Selected_Range_Checks): If the node to be checked is a conversion to
12623 an unconstrained array type, and the expression is a slice, use the
12624 bounds of the slice to construct the required constraint checks.
12625 Improve NOT NULL error messages
12626 (Apply_Constraint_Check): If the context is a null-excluding access
12627 type, diagnose properly the literal null.

12643 Arnaud Charlet <charlet@adacore.com>
12645 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12646 applicable to types that have the With_Type flag set. Returns the
12647 non-limited view of the type, if available, otherwise the type itself.
12648 For class-wide types, there is no direct link in the tree, so we have
12649 to retrieve the class-wide type of the non-limited view of the Etype.
12650 New attributes Static_Initialization and Static_Elaboration_Desired.
12651 Remove the pragma Thread_Body, and the associated flag
12652 Is_Thread_Body in entities, and all related code.

12666 (Root_Type): Handle properly subtypes of class-wide-types.
12669 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12670 class-wide types visible through limited-with clauses.
12671 (Try_Primitive_Operation): When examining all primitive operations of a
12672 tagged type, do not consider subprograms labeled as hidden unless they
12673 belong to a private generic type with a tagged parent.
12674 (Try_Object_Operation): Extensive rewriting, to handle properly various
12675 overloading cases, when several ancestors may have class-wide operations
12676 that are possible candidates, and when the overloaded functions return
12677 array types and have defaulted parameters so that the call may be
12678 interpreted as an indexing.
12679 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12680 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12681 successive actuals before analyzing the call itself.
12682 (Try_Primitive_Operation): A primitive operation is compatible with the
12683 prefix if the prefix has a synchronized type and the type of the formal
12684 is its corresponding record, as can be the case when the primitive
12685 operation is declared outside of the body of the type.
12686 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12687 perform homonym traversal, looking for class-wide operation matches
12688 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12689 access parameters are now restricted to anonymous access types.
12690 (Mark_Allocator): An allocator with a discriminant association parent is
12692 (Try_One_Prefix_Interpretation): If the type of the object is
12693 incomplete, as can be happen when it is a limited view obtained through
12694 a limited_with_clause, the selected component is not part of a prefixed
12696 (Complete_Object_Operation): Diagnose properly an object that is not
12697 aliased when the corresponding controlling formal is an access
12699 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12700 ambiguous calls in prefixed notation, where two primitives differ only
12701 in that the controlling argument of one is an access parameter.
12703 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12704 whether a function that returns an unconstrained type can be inlined.
12705 (Process_Formals): Diagnose properly the illegal use of an incomplete
12706 type in the profile of an access_to_subprogram declaration.
12707 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12708 operations are attached to the corresponding record.
12709 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12710 When processing a primitive of a concurrent type which implements an
12711 interface change the type of all controlling formals to that of the
12712 corresponding record type.
12713 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12714 to determine the tagged type to which a primitive belongs.
12715 (Check_Conventions): Capture condition to ignore a primitive operation
12716 (which is shared between the loop in Check_Conventions and the one in
12717 Check_Convention) in a new local function Skip_Check.
12718 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12719 confusion with Check_Conventions' own Prim_Op local variable.
12720 (Create_Extra_Formals): Test for a tagged result type rather than a
12721 controlling result when determining whether to add a BIP_Alloc_Form
12722 formal and a BIP_Final_List formal to the function.
12723 (Check_Conformance); For parameters that are anonymous access types,
12724 subtype conformance requires that the not null and the constant
12725 indicators must match
12726 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12727 to retrieve the appropriate type when processing a concurrent type
12728 declared within a generic. Minor comment reformatting. Change invocation
12729 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12731 (Analyze_Subprogram_Body): If the return type of a function is an
12732 anonymous access to the limited view of a class-wide type, and the
12733 non-limited view of the type is available, update the type of the
12734 function so that code can be generated.
12735 (Process_Formals): In case of access-subtype itype whose designated
12736 type is also an itype (situation that happens now with access to
12737 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12738 attribute to avoid backend problems.
12739 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12740 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12741 anonymous types' designated types are same before testing
12742 Subtypes_Statically_Match.
12743 (Create_Extra_Formals): Test for a named access parameter that is a
12744 controlling formal as an additional condition for adding an
12745 accessibility level formal. This can occur in the subp type created for
12746 dispatching calls in Expand_Dispatching_Call, and allows calling
12747 Create_Extra_Formals from that procedure rather than special-casing the
12748 extra formals there.
12749 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12750 when the function has a controlling result.
12751 (Check_Returns): Add much more knowledge of the optimization of local
12752 raise statements to gotos, to retain proper warnings in this case.
12753 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12754 nodes when looking for last statement.
12756 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12757 class-wide types visible through limited with clauses.
12758 (Add_One_Interp): If the operands are anonymous access types, the
12759 predefined operator on universal_access is immediately visibles
12760 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12761 other anonymous access types.
12762 (Disambiguate): Take into account CIL convention.
12763 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12765 2007-06-06 Robert Dewar <dewar@adacore.com>

12770 Fix lower bound of tables.
12773 * nlists.adb: Ditto.

12782 * exp_aggr.ads, exp_aggr.adb:
12783 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12784 in extension aggregates.
12785 (Flatten): Other conditions being met, an aggregate is static if the
12786 low bound given by component associations is different from the low
12787 bound of the base index type.
12788 (Packed_Array_Aggregate_Handled): If the component type is itself a
12789 packed array or record, the front-end must expand into assignments.
12790 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12791 Init_Pr, instead of Ancestor_Is_Expression.
12792 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12793 coextension chain root, either generate a list controller or use the
12794 already existing one.
12795 (Static_Array_Aggregate): New procedure to construct a positional
12796 aggregate that can be handled by the backend, when all bounds and
12797 components are compile-time known constants.
12798 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12799 types covering interface types into assignments.
12800 (Replace_Type): move to Build_Record_Aggr_Code.
12801 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12802 interface type, convert to the definite type of the aggregate itself,
12803 so that needed components are visible.
12804 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12805 components and the context is an extended return statement do not
12806 create a transient block for it, to prevent premature finalization
12807 before the return is executed.
12808 (Gen_Assign): Do not generate a call to deep adjust routine if the
12809 component type is itself an array of controlled (sub)-components
12810 initialized with an inner aggregate.
12811 (Component_Check): New name for Static_Check. This name is now more
12812 appropriate, and documentation is added which was missing.
12813 (Component_Check): Add test for bit aligned component value
12814 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12815 Tagged_Comps, name is more appropriate given added function below.
12816 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12820 Robert Dewar <dewar@adacore.com>
12822 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12823 Terminated: Add unchecked type conversion from System.Address to
12824 System.Tasking.Task_Id when calling the predefined primitive
12826 Disable new Ada 05 accessibility check for JVM.NET targets, which
12827 cannot be implemented in a practical way.
12828 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12829 the sources always references the tag of the actual object. Therefore,
12830 if 'Tag is applied in the sources to class-wide interface objects we
12831 generate code that displaces "this" to reference the base of the object.
12832 (Expand_N_Attribute_Reference, case Size): Return specified size if
12833 known to front end.
12834 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12835 has code that displaces the pointer of the object to manage interface
12836 types. However this code must not be executed when the prefix is a
12837 subprogram. This bug caused the wrong expansion of the internally
12838 generated assignment that fills the dispatch table when the primitive
12839 is a function returning a class-wide interface type.
12840 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12841 Set_Attribute_Name for Name_Unaligned_Valid.

12844 Gary Dismukes <dismukes@adacore.com>
12846 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12847 If the initialization is the equivalent aggregate of the initialization
12848 procedure of the type, do not remove it.
12849 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12850 initialized to null from having their expression reset to empty and

12861 references where the prefix must be a simple name.
12863 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12864 Namet. Add new arrays Attribute_Name_Modifies_Prefix and

12872 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12873 constrained subtype for a nominal unconstrained type, use its base type
12874 to check for conformance with the context.
12875 (Resolve_Attribute): Remove test of the access type being associated
12876 with a return statement from condition for performing accessibility
12877 checks on access attributes, since this case is now captured by
12878 Is_Local_Anonymous_Access.
12879 (Analyze_Access_Attribute): Set Address_Taken on entity
12880 (Analyze_Attribute, case Address): Set Address_Taken on entity
12881 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12882 validating an access attribute whose prefix is a current instance.
12883 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12884 applied to dispatching operations, if freezing is required then we set
12885 the attribute Has_Delayed_Freeze in the prefix's entity.
12886 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12887 current scope if access of local subprogram taken
12888 (Analyze_Access_Attribute): Check legality of self-reference even if the
12889 expression comes from source, as when a single component association in
12890 an aggregate has a box association.
12891 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12892 the prefix if it is a protected operation and the attribute is
12893 Unrestricted_Access.
12894 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12895 reference to the base type of the context, to force a constraint check
12896 when the context is an access subtype with an explicit constraint.
12897 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12898 node is rewritten as an interface conversion. leave unanalyzed after
12899 resolution, to ensure that type checking against the context will take

12904 Robert Dewar <dewar@adacore.com>
12906 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12907 wrapper when the full view of the controlling type of an inherited
12908 function that dispatches on result implements interfaces.
12909 (Expand_N_Object_Declaration): In cases where the type of the
12910 declaration is anonymous access, create finalization list for it.
12911 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12912 if the object has no explicit initialization, to match description of
12913 functionality of pragam Persistent_BSS.
12914 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12915 new function to build static aggregates, to replace initialization call
12916 when static initialization is desired.
12917 (Freeze_Type): Generate a list controller for an access type whenever
12918 its designated type has controlled anonymous access discriminants.
12919 (Build_Equivalent_Aggregate): New procedure to compute a static
12920 aggregate to be used as default initialization for composite types,
12921 instead of a generating a call to the initialization procedure for the
12923 (Build_Initialization_Call): When available, replace a call to the
12924 initialization procedure with a copy of the equivalent static aggregate
12926 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12927 declarations for objects of a class-wide interface type, rather than
12928 just identifiers, to prevent visibility problems.
12929 (Expand_N_Object_Declaration): When expanding the declaration for an
12930 object of a class-wide interface type, preserve the homonym chain of
12931 the original entity before exchanging it with that of the generated
12932 renaming declaration.
12933 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12934 active, because there is no way to handle the exception.
12935 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12936 to do a minimum decoration of the Access_Disp_Table list.
12937 (Expand_Record_Controller): Avoid the addition of the controller between
12938 the component containing the tag of a secondary dispatch table and its
12939 adjacent component that stores the offset to the base of the object.
12940 This latter component is only generated when the parent type has
12941 discriminants ---documented in Add_Interface_Tag_Components).
12942 (Apply_Array_Size_Check): Removed, no longer needed.
12943 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12944 components, create a Master_Entity for it only if it contains tasks.

12947 (Freeze_Record_Type): Remove code associated with creation of dispatch
12949 (Init_Secondary_Tags): Update type of actuals when generating calls to
12950 Ada.Tags.Set_Offset_To_Top
12951 (Stream_Operation_OK): Disable use of streams compiling under no
12953 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12954 if Has_Init_Expression set.
12955 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12956 Register_Primitive, which provides the same functionality.
12957 (Requires_Init_Proc): Return false in case of interface types.
12958 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12960 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12961 is always associated with a predefined primitive because the internal
12962 entities associated with interface types are not predefined primitives.
12963 Therefore, the call to Is_Internal is replaced by a call to the
12964 function Is_Predefined_Dispatching_Operation.
12965 (Make_Eq_If): When generating the list of comparisons for the
12966 components of a given variant, omit the controller component that is
12967 present if the variant has controlled components.
12969 2007-06-06 Javier Miranda <miranda@adacore.com>
12970 Hristian Kirtchev <kirtchev@adacore.com>
12971 Bob Duff <duff@adacore.com>
12973 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12974 handle the creation of finalization lists and calls for nested
12975 coextensions when the root of the chains is part of a return statement.
12976 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12978 (Expand_Record_Equality): Skip components that are interface types.
12979 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12980 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12981 with Rewrite_Coextension. Change the condition for detecting coextension
12983 (Is_Local_Access_Discriminant): Removed.
12984 (Rewrite_Coextension): New routine which rewrites a static coextension
12985 as a temporary and uses its unrestricted access in the construction of
12987 (Complete_Coextension_Finalization): New routine. Generate finalization
12988 attachment calls to all delayed coextensions.
12989 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12990 the allocator is not a coextension itself and has delayed coextensions.
12991 If the current allocator is controlled, but also a coextension, delay
12992 the generation of the finalization attachment call.
12993 Rename local variable "Node" to "Nod" in order to avoid confusion with
12995 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12996 limited types that are not inherently limited. Such an allocator is
12997 illegal, but is generated by the expander for a return statement, to
12998 copy the result onto the secondary stack. This is the only case where a
12999 limited object can be copied. Generate code to displace the pointer
13000 to the object if the qualified expression is a class-wide interface
13001 object. Such displacement was missing and hence the copy of the object
13003 (Apply_Accessibility_Check): Handle allocated objects initialized in
13005 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13006 and Expand_Allocator_Expression. Allocating class-wide interface objects
13007 this routine displaces the pointer to the allocated object to reference
13008 the component referencing the corresponding secondary dispatch table.
13009 Expand_Allocator_Expression): Add missing support to allocate class-wide
13010 interface objects initialized with a qualified expression.
13011 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13012 function result type, and use the finalization list associated with the
13013 function scope in that case (such an anonymous type should not be
13014 treated like an access parameter's type).
13016 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13017 Gary Dismukes <dismukes@adacore.com>
13018 Javier Miranda <miranda@adacore.com>
13020 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13021 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13022 required exception handler.
13023 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13024 properly the case of a function whose return type is a limited
13025 class-wide interface type. Modify the code of the accessibility
13026 check to handle class-wide interface objects. In this case we need to
13027 displace "this" to reference the primary dispatch table to get access
13028 to the TSD of the object (to evaluate its accessibility level).
13029 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13030 rather than a controlling result as one of the conditions for
13031 generating tests of the implicit BIP_Alloc_Form formal. The
13032 initialization assignment is also handled according to whether the
13033 result is tagged instead of controlling.
13034 In the case where the init assignment is inserted in the "then" part of
13035 the allocation conditional, rewrite the target to be a dereference of
13036 the implicit BIP_Object_Access formal.
13037 If the returned value is unconstrained and created on the secondary
13038 stack, mark the enclosing block and function so that the secondary
13039 stack is not reclaimed on return.
13040 Treat returns from functions with controlling results similarly to
13041 returns from functions with unconstrained result subtypes.
13042 If the object returned is unconstrained, and an allocator must be
13043 created for it, analyze the allocator once the block for the extended
13044 return is installed, to ensure that finalizable components
13045 of the expression use the proper finalization list. Guard the call to
13046 Move_Final_List with a check that there is something to finalize.
13047 (Make_Tag_Ctrl_Assignment): Use "old" handling
13048 of controlled type assignment for virtual machines, since new code uses
13049 unsupported features (such as direct access to bytes in memory).
13051 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13052 Ed Schonberg <schonberg@adacore.com>
13054 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13055 accessibility actual, check for the case of an aliased object that has
13056 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13057 we fall into processing for the attribute rather than the name of the
13059 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13060 formal has its address taken in the body, create a temporary to capture
13061 value. If the return type is a limited interface, do not treat the
13062 return value as Controlled.
13063 (Is_In_Place_Function): If the return type is a limited interface,
13064 treat as returning in place. The actual returned object may not always
13065 be limited, but the caller has to assume that it is returned in place.
13066 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13067 context of an allocator, use the correct finalization chain (that is,
13068 the chain belonging to the access type, rather than the chain belonging
13069 to the current scope).
13070 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13071 result type rather than a controlling result as a precondition for
13072 adding an allocation form actual to a build-in-place call.
13073 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13074 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13075 primitive in the dispatch tables. This work is now done by Make_DT when
13076 the type is frozen.
13077 (Register_Predefined_DT_Entry): Removed.
13078 (Add_Return): If end label is not present, use sloc of last statement
13079 for generated return statement in procedure, for better gdb behavior
13081 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13082 object address nodes to ensure proper processing by routines like
13084 (Expand_Call): Fix generation of validity check for parameter
13085 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13086 the allocation form parameter if the result subtype is constrained,
13087 except when the function has a controlling result.
13088 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13089 rather than Is_Controlled and Has_Controlled_Component, since we want to
13090 include class-wide result types in this treatment. Also test for a
13091 controlling result, since that also requires passing a finalization
13093 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13094 even when the result subtype is constrained, to handle calls involving
13095 controlling results.
13096 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13097 is now called even when the result subtype is constrained, to handle
13098 calls involving controlling results.
13099 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13100 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13101 now performs the test).
13102 (Make_Build_In_Place_Call_In_Object_Declaration):
13103 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13104 constrained, to handle calls involving controlling results.
13105 (Add_Return): Accomodate rewritten pattern from local raise to goto
13106 transformation, so that we still recognize an transfer statement
13107 and do the right thing here in that case.
13108 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13109 and end of subprogram code.
13110 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13111 support for primitives that are functions (without formals) with a
13112 controlling result.
13113 (Inherited_From_Formal): If the actual subtype has not generic parent
13114 type, it is not an actual for a formal derived type, and there is no
13115 operation to inherit from the formal.
13117 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13118 Thomas Quinot <quinot@adacore.com>
13120 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13121 inserted cleanup code appropriately for GDB use.
13122 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13123 exception handler for Deep_Adjust or Deep_Finalize.
13124 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13125 Raise_From_Controlled_Operation is available, use a call to that
13126 subprogram instead of a plain "raise Program_Error" node to raise
13127 Program_Error if an exception is propagated from an Adjust or Finalize
13129 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13130 appears in the optional statement list of a triggering alternative, the
13131 scope actions can be inserted directly there, and not in the list that
13132 includes the asynchronous select itself.
13134 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13135 Robert Dewar <dewar@adacore.com>
13136 Hristian Kirtchev <kirtchev@adacore.com>
13138 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13139 generated exception handler appropriately when debugging generated code.
13140 Deal properly with No_Exception_Propagation restriction mode.
13141 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13142 System.Address to System.Tasking.Task_Id when processing the result of
13143 the predefined primitive _disp_get_task_id.
13144 (Expand_N_Asynchronous_Select): Clarify comment.
13145 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13146 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13147 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13148 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13149 privals and for generated call to Complete_Entry_Body, for better gdb
13151 (Copy_Result_Type): Utility to construct a parameter and result profile
13152 for protected functions whose return type is an anonymous access to
13154 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13156 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13157 point when the local-raise-to-goto transformation has taken place.
13159 2007-06-06 Javier Miranda <miranda@adacore.com>
13160 Nicolas Setton <setton@adacore.com>
13162 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13163 functionality when the backend is generating code.
13164 Otherwise any serious error
13165 reported by the backend calling the frontend routine Error_Msg
13166 changes the Compilation_Mode to Check_Semantics, disables the
13167 functionality of this routine and causes the generation of
13168 spureous additional errors.
13170 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13171 debugging information now generated by the compiler for fat-pointer
13173 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13175 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13177 2007-06-06 Thomas Quinot <quinot@adacore.com>
13179 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13180 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13181 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13182 For a remote call to a function with a classwide return type, apply an
13183 E.4(18) check to the returned value.
13184 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13185 stream attributes of the designated type of an RACW, as they are not
13186 dispatching primitive operations.
13188 2007-06-06 Geert Bosch <bosch@adacore.com>
13190 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13192 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13194 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13195 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13197 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13199 2007-06-06 Javier Miranda <miranda@adacore.com>
13201 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13202 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13204 2007-06-06 Javier Miranda <miranda@adacore.com>
13206 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13207 deallocation of class-wide interface objects.
13208 (Expand_Dispatching_Constructor_Call): Take into account that if the
13209 result of the dispatching constructor is an interface type, the
13210 function returns a class-wide interface type; otherwise the returned
13211 object would be actual. The frontend previously accepted returning
13212 interface types because Expand_Interface_Actuals silently performed
13213 the management of the returned type "as if" it were a class-wide
13215 (Expand_Dispatching_Constructor_Call): Replace call to
13216 Make_DT_Access_Action by direct call to Make_Function_Call.
13218 2007-06-06 Robert Dewar <dewar@adacore.com>
13219 Ed Schonberg <schonberg@adacore.com>
13221 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13222 compute masking constant, since we now set Esize properly to the
13224 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13225 to match the alignment.
13226 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13227 packed arrays of 8 bits or less.
13229 * freeze.adb (Freeze_Entity): When freezing the formals of a
13230 subprogram, freeze the designated type of a parameter of an access type
13231 only if it is an access parameter.
13232 Increase size of C convention enumeration object
13233 (Freeze_Entity, array type case): Make sure Esize value is properly
13234 adjusted for the alignment if it is known.
13235 (Freeze_Entity, array type case): When checking bit packed arrays for
13236 the size being incorrect, check RM_Size, not Esize.
13237 (Freeze_Record_Type): Check for bad discriminated record convention
13238 (In_Exp_Body): Return true if the body is generated for a subprogram
13239 renaming, either an attribute renaming or a renaming as body.
13240 (Check_Itype): If the designated type of an anonymous access component
13241 is a non-protected subprogram type, indicate that it is frozen, to
13242 prevent out-of-scope freeze node at some subsequent call.
13243 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13244 only if the subprogram is neither imported nor exported, as well as the
13245 NCA descriptor class if the subprogram is exported.

13250 Gary Dismukes <dismukes@adacore.com>
13252 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13253 default initialization on an imported object, when there is no
13254 initialization call generated for it.
13255 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13258 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13259 Static_Elaboration_Desired.
13260 Remove pragma Thread_Body.
13261 Implement a new pragma No_Body
13262 Removes the Explicit_Overriding pragma
13263 Remove Optional_Overriding pragma
13264 (Prag): Deal with Universal_Aliasing.
13265 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13266 Pragma_CIL_Constructor): New names.
13268 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13269 uses the equivalent aggregate of a type must be treated as an implicit
13271 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13272 has none of the other categories.
13273 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13274 to apply Import to an object renaming declaration.
13276 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13277 from a C++ class should be declared as limited and that it will be
13278 considererd limited.
13279 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13280 should be declared as limited and that it will be considererd limited.
13281 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13282 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13283 (Analyze_Pragma): Deal with Universal_Aliasing.
13284 (Sig_Flags): Likewise.
13285 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13286 (Overflow_Checks_Unsuppressed): New flag.
13287 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13288 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13289 case of JVM or .NET targets, and compiling user code.
13290 Add debugging convenience routine rv
13292 2007-06-06 Robert Dewar <dewar@adacore.com>
13294 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13295 are interface type.
13296 (Build_Elementary_Input_Call): For floating-point use right type in the
13297 absence of strange size or stream size clauses.
13298 (Build_Elementary_Write_Call): Same fix
13299 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13300 set to value that does not match base type size.
13302 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13304 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13305 object of a limited type can be initialized with a call to a function
13306 that returns in place. If the limited type has unknown discriminants,
13307 and the underlying type is a constrained composite type, build an actual
13308 subtype from the function call, as is done for private types.
13309 (Side_Effect_Free): An expression that is the renaming of an object or
13310 whose prefix is the renaming of a object, is not side-effect free
13311 because it may be assigned through the renaming and its value must be
13312 captured in a temporary.
13313 (Has_Controlled_Coextensions): New routine.
13314 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13315 as is done for other limited types.
13316 (Non_Limited_Designated_Type): new predicate.
13317 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13319 Remove all handling of with_type clauses.
13321 * par-ch10.adb: Remove all handling of with_type clauses.
13323 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13324 checksum if the main source could not be parsed.
13325 (Loat_Unit): When processing a child unit, determine properly whether
13326 the parent unit is a renaming when the parent is itself a child unit.
13327 Remove handling of with_type clauses.
13329 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13362 Ed Schonberg <schonberg@adacore.com>
13364 * g-comlin.ads, g-comlin.adb:
13365 Add new warning for renaming of function return objects
13367 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13368 (Tree_Read): Use size of object instead of type'object_size, since the
13369 latter is incorrect for packed array types.
13370 (Tree_Write): Same fix
13372 * opt.ads: Add new warning for renaming of function return objects
13373 (Generating_Code): New boolean variable used to indicate that the
13374 frontend as finished its work and has called the backend to process
13375 the tree and generate the object file.
13376 (GCC_Version): Is now private
13377 (Static_Dispatch_Tables): New constant declaration.
13378 (Overflow_Checks_Unsuppressed): New flag.

13383 (Warn_On_Unrepped_Components): New flag.
13385 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
13386 unit is a compilation unit, rather than relying on its scope, so that
13387 Standard can be renamed.
13388 (Analyze_Object_Renaming): Add new warning for renaming of function
13390 Also reject attempt to rename function return object in Ada 83 mode.
13391 (Attribute_Renaming): In case of tagged types, add the body of the

13835 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
13836 associated with dispatch tables is known at compile time.
13837 (Get_Value): If an association in a record aggregate has a box
13838 association, and the corresponding record component has a default
13839 expression, always copy the default expression, even when the
13840 association has a single choice, in order to create a proper
13841 association for the expanded aggregate.

14940 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
14942 (Resolve_Actuals): If an actual is an allocator for an access parameter,
14943 the master of the created object is the innermost enclosing statement.
14944 (Remove_Conversions): For a binary operator, check if type of second

14977 object of a null-excluding access type then don't require the
14978 the object declaration to have an expression and don't emit a

15108 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15109 "abstract subprograms must be visible" message, whether or not the type

15137 Remove no longer used entities.
15139 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

15179 "X'Unrestricted_Access = Y'Access" and so forth to match.

15187 attempt to derive from a synchronized tagged type.
15188 (Analyze_Type_Declaration): If there is a incomplete tagged view of the

15200 to stand-alone object declarations as well as component declarations.
15201 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15202 prevent accidental overwriting when enclosing package appears in
15203 a limited_with_clause.

15214 with abstract interfaces.
15215 (Analyze_Subtype_Indication): Resolve the range with the given subtype

15243 (Compile_Sources): Do nothing, not even check if the source is up to
15244 date, if its project is externally built.
15245 (Compile): When compiling a predefined source, add -gnatpg
15246 as the second switch, after -c.
15247 (Compile_Sources): Allow compilation of Annex J renames without -a
15248 (Is_In_Object_Directory): Check if the ALI file is in the object
15249 even if there is no project extension.
15250 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15251 gnatbind if the ALI file effectively exists.
15252 (Initialize): Add the directory where gnatmake is invoked in front of

15278 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15279 when -gnatg is not specified.

15309 (Convert_Aggr_In_Allocator): If the allocator is for an access
15310 discriminant and the type is controlled. do not place on a finalization
15311 list at this point. The proper list will be determined from the

15330 succeed in that case, even when the expression originates from a
15331 parameter of the containing subprogram.
15332 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15333 under No_Dispatching_Calls restriction. During the semantic analysis
15334 we already notified such violation.

15352 initialize most the TSD components by means of an aggregate.
15353 Modify the declaration of the object containing the TSD
15354 because we now expand code that has a higher level of abstraction.
15355 The TSD has a discriminant containing the Inheritance Depth Level,
15356 value that is used in the membership test but also to fix the size
15357 of the table of ancestors.
15358 (Expand_Interface_Conversion): Insert function body at the closest place
15359 to the conversion expression, to prevent access-before-elaboration
15360 errors in the backend.

15391 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15396 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15399 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15400 First (Parameter_Associations ()) with the call to First_Actual that
15401 returns an actual parameter expression for both named and positional

15405 check violation of restriction No_Dispatching_Calls.
15406 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15407 controlling argument.

15413 specify Any_Limited_Interface, and this functionality is already
15414 provided by the function Has_Abstract_Interfaces.
15415 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15416 support concurrent types implementing interfaces.
15417 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15418 specify kind Any_Limited_Interface, and this functionality is already

15421 CW_Or_Controlled_Type whenever the issue is related to
15422 using or not the secondary stack.

15440 without a corresponding body, generate RACW subprogram bodies in the
15441 spec (just as we do for the task activation call).
15442 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15443 Is_Abstract_Type. Make sure these are called only when appropriate.

15462 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15463 a protected version of an operation declared in the private part of
15464 a protected object, because they may be invoked through a callback.
15465 (Set_Privals): If the type of a private component is an anonymous access
15466 type, do not create a new itype for each protected body.
15467 If the body of a protected operation creates
15468 controlled types (including allocators for class-widetypes), the
15469 body of the corresponding protected subprogram must include a

15476 for a possible overriding candidate.
15477 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15478 hold an actual parameter value since its initialization is separated

15488 Build_From_Any_Call.
15489 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15490 E_Constant, depending upon Variable formal.
15491 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,

15496 the unit being compiled is the one that contains the stub type.
15497 Change primitive operation name for the RACW associated with a RAS
15498 from Call to _Call so it cannot clash with any legal identifier.
15499 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15501 (Append_RACW_Bodies): New subprogram.
15502 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15503 Add_Receiving_Stubs_To_Declarations functions.

15509 registering the receiving stubs at the end of the 'Stmts' list.
15510 (RCI_Package_Locator): Pass the new Version generic formal when
15511 instantiating a RCI_Locator package.
15512 (Build_From_Any_Function): To compute the High bound for an
15513 unconstrained array actual, we add the Low bound with the length.
15514 Thus we must convert the low bound and the length to an appropriate
15515 type before doing the sum.
15516 (Build_Subprogram_Receiving_Stubs, PolyORB):
15517 * Retrieve the extra formals parameters at the
15518 end of the parameter stream.
15519 * Use Move_Any_Value to write back out parameters
15520 after executing the request as it is more efficient
15521 than Copy_Any_Value.
15522 * Build the any containing Extra Formals with the
15523 appropriate typecode.
15524 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15525 empty Component_List.

15538 function with the first not implicit parent type.
15539 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15540 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15541 typecode from the Etype. Therefore we retrieve the correct typecode
15542 with a call to Get_Any_Type.
15543 (Copy_Specification): Do controlling formal type substitution based on
15544 Is_Controlling_Formal flag, instead of caller-provided object type.
15545 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15546 a RACW primitive operation, we might get a subprogram declaration for an
15547 ancestor of the RACW designated type (not for the designated type
15548 itself), in the case where this operation is inherited. In this case we
15549 have no easy means of determining the original tagged type for which
15550 the primitive was declared, so instead we now rely on
15551 Copy_Specification to use the Is_Controlling_Formal flag to determine
15552 which formals require type substitution.

15562 run-time subprogram CW_Membership by call to Build_CW_Membership.
15563 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15564 by a function call, a temporary must be created before expanding the
15565 Constructor_Call itself, to prevent out-of-order elaboration in the
15566 back-end when stack checking is enabled..

15639 (Stack_String): Add this String that contains the name of the Stack
15640 package in the project file.
15641 (Packages_To_Check_By_Stack): Add this list that contains the packages
15642 to be checked by gnatstack, which are the naming and the stack packages.
15643 (Check_Files): If no .ci files were specified for gnatstack we add all
15644 the .ci files belonging to the projects, including binder generated
15646 (Non_VMS_Usage): Document that gnatstack accept project file switches.
15647 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
15648 Add gnatstack to the list of commands that use project file related
15649 switches, and get the single attribute Switches from the stack package
15650 in a project file when calling gnatstack. Parse the -U flag for
15651 processing files belonging to all projects in the project tree.
15652 Remove all processing for command Setup

15695 standard 8bits encoding.
15696 (WS2SU): As above but converting from wide-sring to string.
15697 This is needed as it is necessary to have access to both versions in the
15698 runtime for the form parameter encoding support.
15699 This set of patch add support for the encoding form parameter.
15700 (S2WS): Improve implementation to handle cases where the filename is not
15701 UTF-8 encoded. In this case we default to using the current code page
15702 for the conversion.
15704 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15705 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15714 corresponding encoding value into AFCB structure.
15715 (Reset): Pass the encoding value to freopen.
15716 (Close): Move the call to Lock_Task to the beginning of the procedure.

15749 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15750 __gnat_adjust_context_for_raise.
15751 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15752 implementation of floating point operations as native x86 targets.
15753 So the FPU should be initialized in the same way using finit. Fix
15754 floating point operations accuracy issues.
15755 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15756 member in struct sigaction, so as to avoid warning for incompatible

15772 Javier Miranda <miranda@adacore.com>
15774 * lib-xref.ads, lib-xref.adb:
15775 Modify the loop that collects type references, to include interface
15776 types that the type implements. List each of these interfaces when
15777 building the entry for the type.
15778 (Generate_Definition): Initialize component Def and Typ of new entry
15779 in table Xrefs, to avoid to have these components unitialized.
15780 (Output_References): Split Is_Abstract flag into
15781 Is_Abstract_Subprogram and Is_Abstract_Type.
15782 (Generate_Reference): Add barrier to do not generate the warning
15783 associated with Ada 2005 entities with entities generated by the

15825 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
15826 it no longer destroys the contents of Name_Buffer or Name_Len and
15827 non-standard and invalid names are handled better.
15828 (Get_Decoded_Name_String): Improve performance by using
15829 Name_Has_No_Encodings flag in the name table.
15830 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
15831 Used for debugging printouts.

15834 Javier Miranda <miranda@adacore.com>
15835 Bob Duff <duff@adacore.com>
15837 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15838 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15839 there is no need to generate always a record_definition_node in case
15840 of synchronized interface types.
15841 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15842 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15843 illegal in Ada 95, in cases where it is legal. Change the warnings to
15844 errors in other cases. Don't give the error unless the "not null"
15845 parses properly. Correct the source position at which the error occurs.
15846 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15847 P_Null_Exclusion, to suppress "not null" warnings.

15899 Entry for pragma Unreferenced_Objects
15901 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
15902 switches, without repetition of "eD". Make sure that last character of
15903 -gnatep= switch is not taken as -gnat switch character.
15904 Complete rewrite of circuit for handling saving compilation options
15905 Occasioned by need to support dot switchs for -gnatw, but cleans up

15923 the default project path, initially done during elaboration of the
15925 If the prefix returned by Sdefault is null, get the prefix from a call
15926 to Executable_Prefix_Path.
15927 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15930 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
15931 canonical directory name to open the directory from which files are
15933 (Record_Other_Sources): Idem.
15934 (Locate_Directory): Add the possibility to create automatically missing
15935 directories when Setup_Projects is True.

15938 library source copy dir and exec dir.
15940 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15943 2007-04-06 Robert Dewar <dewar@adacore.com>

15977 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
15978 full word is no longer compared twice.
15980 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15982 * sem_ch10.adb (Install_Limited_Context_Clauses.
15983 Expand_Limited_With_Clause): Use a new copy of selector name in the
15984 call to Make_With_Clause. This fixes the tree structure for ASIS
15985 purposes. Nothing is changed in the compiler behaviour.
15986 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15987 a package renaming.
15988 (Install_Limited_With_Clauses): Do not install non-limited view when it
15989 is still incomplete.
15991 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15992 Gary Dismukes <dismukes@adacore.com>
15994 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15995 when capturing size information, instead of base type, which for a
15996 formal array type will be the unconstrained type.
15997 (Analyze_Formal_Object_Declaration): Add check for illegal default
15998 expressions for a formal in object of a limited type.
15999 (Instantiate_Object): Ditto.
16000 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16001 because they were defaulted in the formal package and no check applies
16003 (Check_Formal_Package_Instance): Extend conformance check to other
16004 discrete types beyond Integer.
16005 (Process_Default): Copy directly the unmatched formal. A generic copy
16006 has already been performed in Analyze_Formal_Package.
16007 (Analyze_Associations): If a formal subprogram has no match, check for
16008 partial parametrization before looking for a default, to prevent
16010 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16011 not set the instantiation environment before analyzing the actuals.
16012 Fixes regression on 8515-003 with implementation of AI-133.
16013 Set_Instance_Env checks whether the generic unit is a predefined
16014 unit, in which case the instance must be analyzed with the latest Ada
16015 mode. This setting must take place after analysis of the actuals,
16016 because the actuals must be analyzed and frozen in the Ada mode extant
16017 outside of the current instantiation.
16018 (Save_Env, Restore_Env): Preserve and restore the configuration
16019 parameters so that predefined units can be compiled in the proper Ada
16021 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16022 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16023 and Is_Abstract_Type.
16024 (Analyze_Formal_Package): For better error recovery, Add exception
16025 handler to catch Instantion_Error, which can be raised in
16026 Analyze_Associations
16028 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16029 Bob Duff <duff@adacore.com>
16030 Gary Dismukes <dismukes@adacore.com>
16032 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16033 prefix type is a discriminated subtype of the type of the formal.
16034 (Analyze_Allocator): Collect all coextensions regardless of the context.
16035 Whether they can be allocated statically is determined in exp_ch4.
16036 (Analyze_Selected_Component): If the prefix is a limited view and the
16037 non-limited view is available, use the non-limited one.
16038 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16039 therefore illegal), suggest a qualified expression rather than a type
16040 conversion, because a type conversion would be illegal in this context.
16041 (Anayze_Allocator): Trace recursively all nested allocators so that all
16042 coextensions are on the corresponding list for the root. Do no mark
16043 coextensions if the root allocator is within a declaration for a stack-
16044 allocated object, because the access discriminants will be allocated on
16046 (Analyze_Call): Remove restriction on calls to limited functions for the
16047 cases of generic actuals for formal objects, defaults for formal objects
16048 and defaults for record components.
16049 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16050 element list. Their expansion is delayed until the enclosing allocator
16051 is processed and its finalization list constructed.
16052 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16053 for an operation with the given name among the primitive operations of
16054 the corresponding record type.
16055 (Analyze_Selected_Component): If the prefix is a task type that
16056 implements an interface, and there is no entry with the given name,
16057 check whether there is another primitive operation (e.g. a function)
16059 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16060 properly the indexing of a function call written in prefix form, where
16061 the function returns an array type, and all parameters of the function
16062 except the first have defaults.
16063 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16064 the original operands, rather than relocating them, for efficiency and
16065 to work properly when an operand is overloaded.
16066 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16067 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16068 (Analyze_Selected_Component): If the prefix is a private extension, only
16069 scan the visible components, not those of the full view.
16070 (Try_Primitive_Operation): If the operation is a procedure, collect all
16071 possible interpretations, as for a function, because in the presence of
16072 classwide parameters several primitive operations of the type can match
16073 the given arguments.
16075 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16076 Robert Dewar <dewar@adacore.com>
16078 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

16084 Thomas Quinot <quinot@adacore.com>
16086 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16087 out of Analyze_Package_Declaration, because processing must be applied
16088 to package bodies as well, for deferred constants completed by pragmas.
16089 (Analyze_Package_Declaration): When the package declaration being
16090 analyzed does not require an explicit body, call Check_Completion.
16091 (May_Need_Implicit_Body): An implicit body is required when a package
16092 spec contains the declaration of a remote access-to-classwide type.

16104 a RAS as Comes_From_Source to get proper view switching when installing
16105 private declarations.
16106 Provite a placeholder nested package body along with the nested spec
16107 to have a place for Append_RACW_Bodies to generate the calling stubs
16108 and stream attributes.

16139 object O, use the access level of O.
16140 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16141 rather than local Same_Formal_Type, to check whether protected operation
16142 overrides an inherited one.
16143 (Same_Formal_Type): New predicate, used when matching signatures of
16144 overriding synchronized operations, to handle the case when a formal
16145 has a type that is a generic actual.
16146 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16147 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

16163 same result than Is_Ancestor.
16164 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16165 (Collect_Synchronized_Interfaces): Removed because the subprogram
16166 Collect_Abstract_Interfaces provides this functionality.

16212 high bound is constant and the slice is empty. Tidy.
16213 (tree_transform, case N_Op_Not): Handle properly the case where the
16214 operation applies to a private type whose full view is a modular type.
16215 (Case_Statement_To_gnu): If an alternative is an E_Constant with an

16217 representing the choice value to ensure the corresponding GCC tree is
16218 of the proper kind.
16219 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16220 instead of just the operands, as the base GCC stabilize_reference does.
16221 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16222 requested; otherwise fail.
16223 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16483 (mainly static expression evaluation).
16484 Reword some continuation messages
16485 Add some \\ sequences to continuation messages
16486 (Resolve_Call): Refine infinite recursion case. The test has been

16500 during analysis, and use May_Be_Lvalue to distinguish read/write.
16501 (Valid_Array_Conversion): New procedure, abstracted from
16502 Valid_Conversion, to incorporate accessibility checks for arrays of
16503 anonymous access types.
16504 (Valid_Conversion): For a conversion to a numeric type occurring in an
16505 instance or inlined body, no need to check that the operand type is
16506 numeric, since this has been checked during analysis of the template.

16536 (Unimplemented): Temporary function raised by the body of new
16538 (Leap_Sec_Ops): New package in the private part of Ada.Calendar. This
16539 unit provides handling of leap seconds and is used by the new Ada 2005
16540 packages Ada.Calendar.Arithmetic and Ada.Calendar.Formatting.
16541 (Split_W_Offset): Identical spec to that of Ada.Calendar.Split. This
16542 version returns an extra value which is the offset to UTC.

17021 sem_util and renamed as Collect_All_Abstract_Interfaces.
17022 (Set_All_DT_Position): Hidden entities associated with abstract
17023 interface primitives are not taken into account in the check for

17035 alias of a predefined dispatching primitive.
17036 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17037 compiling under full ABI compatibility mode we avoid the generation of
17038 calls to run-time services that fill the dispatch tables because under
17039 this mode we currently inherit the dispatch tables in the IP subprogram.
17040 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17041 (Expand_Interface_Conversion): Use an address as the type of the formal
17042 of the internally built function that handles the case in which the

17093 we request a discriminal value only in case of discriminants.
17094 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17095 assignments where the target subtype is unconstrained and the target
17096 object is a parameter or dereference (other aliased cases are known

17212 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17213 are build-in-place function calls.
17214 (Replace_Self_Reference): New subsidiary of
17215 Make_OK_Assignment_Statement, to replace an access attribute that is a
17216 self-reference into an access to the appropriate component of the
17217 target object. Generalizes previous mechanism to handle self-references
17218 nested at any level.
17219 (Is_Self_Referential_Init): Remove, not needed.

17226 default initialization.
17227 (Make_OK_Assignment_Statement): If the expression is of the form
17228 Typ'Acc, where Acc is an access attribute, the expression comes from a
17229 default initialized self-referential component.
17230 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17231 that has been derived from several abstract interfaces we must also

17237 Robert Dewar <dewar@adacore.com>
17240 (Expand_Access_To_Protected_Op): If the context indicates that an access
17241 to a local operation may be transfered outside of the object, create an
17242 access to the wrapper operation that must be used in an external call.
17243 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17244 target, pass the Valid attribute applied to a floating-point prefix on
17245 to the back end without expansion.

17247 the allocated storage when it is specified by a per-object expression.

17260 subcomponent's enclosing variable is aliased with a constrained subtype.
17261 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17262 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17263 an aliased prefix must be known to be constrained in order to use True
17264 for the attribute value, and now it's possible for some aliased views
17265 to be unconstrained.
17267 2006-10-31 Robert Dewar <dewar@adacore.com>
17269 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue

17280 otherwise we incorrectly register the tag of the interface in the final
17282 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17283 generate the wrapper if the parent primitive is abstract. This is
17284 required to report the correct error message.
17285 (Expand_N_Subtype_Indication): Do validity checks on range
17286 (Clean_Task_Names): If an initialization procedure includes a call to

17290 compatibility for interfacing with CPP by default.
17291 (Expand_N_Object_Declaration): Only build an Adjust call when the

17294 (Expand_N_Object_Declaration): Check for object initialization that is a
17295 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17296 Object_Declaration to the call.
17297 (Freeze_Type): When the designated type of an RACW was not frozen at the
17298 point where the RACW was declared, validate the primitive operations
17299 with respect to E.2.2(14) when it finally is frozen.
17300 (Build_Initialization_Call,Expand_Record_Controller): Rename
17301 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17302 return-by-reference has no meaning in Ada 2005.
17303 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17304 to register tag of the immediate ancestor interfaces in the
17305 run-time structure.

17307 initialization of extension aggregates with abstract interfaces.
17308 (Build_Master_Renaming): Make public, for use by function declarations
17309 whose return type is an anonymous access type.
17310 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17311 Insert_List_Before_And_Analyze after the generation of the specs
17312 associated with null procedures.

17314 (Init_Secondary_Tags): Update documentation.
17315 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17316 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17317 then generate code to inherit the contents of the dispatch table
17318 directly from the ancestor.
17319 (Expand_Record_Controller): Insert controller component after tags of
17320 implemented interfaces.
17321 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17322 create null procedure overridings when null procedures are inherited

17325 declarations for overriding null primitives inherited from interfaces.
17326 (Is_Null_Interface_Procedure): New function in
17327 Make_Null_Procedure_Specs.
17328 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17329 immediate ancestor of a tagged type is an abstract interface type we
17330 must generate the specification of the predefined primitives associated
17331 with controlled types (because the dispatch table of the ancestor is
17332 null and hence these entries cannot be inherited). This is required to
17333 elaborate well the dispatch table.

17347 the maximum for type T.
17348 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17349 when the allocator is initialized by a build-in-place call, since the
17350 allocator is already rewritten as a reference to the function result,
17351 and this prevents an unwanted duplication of the function call.
17352 Add with and use of Exp_Ch6.
17353 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17354 is a call to build-in-place function and apply
17355 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17356 untagged designated types).
17357 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17358 optimization if source or target is biased.
17359 (Expand_N_Allocator): Add comments for case of an allocator within a

17372 (Expand_N_Assignment_Statement): Call
17373 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a

17375 assignments that come from aggregates.
17376 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17377 in order to alleviate the upward compatibility introduced by AI-318.
17378 (Expand_N_Extended_Return_Statement): Add support for handling the
17379 return object as a build-in-place result.
17380 (Expand_Non_Function_Return): Implement simple return statements nested
17381 within an extended return.
17382 (Enable_New_Return_Processing): Turn on the new processing of return
17384 (Expand_Non_Function_Return): For a return within an extended return,
17385 don't raise Program_Error, because Sem_Ch6 now gives a warning.

17392 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17393 validity checking of assignments to elementary record components.
17394 (Expand_N_Return_Statement): return Class Wide types on the secondary
17395 stack independantly of their controlled status since with HIE runtimes,
17396 class wide types are not potentially controlled anymore.
17398 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17401 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17402 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17403 it expects a block, procedure, or task. The return statement will get
17404 turned into a block, and Expand_Cleanup_Actions will happen then.

17411 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17413 (Expand_Inlined_Call): Tagged types are by-reference types, and
17414 therefore should be replaced by a renaming declaration in the expanded
17415 body, as is done for limited types.
17416 (Expand_Call): If this is a call to a function with dispatching access
17417 result, propagate tag from context.
17418 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17420 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17421 build-in-place when the right-hand side of an assignment is a
17422 build-in-place function call.
17423 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17424 of the explicit dereference of the allocator to the result subtype of
17425 the build-in-place function. This is needed to satisfy type checking
17426 in cases where the caller's return object is created by an allocator for
17427 a class-wide access type and the type named in the allocator is a
17429 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17430 conversion of the reference to the declared object to the result subtype
17431 of the build-in-place function. This is needed to satisfy type checking
17432 in cases where the declared object has a class-wide type. Also, in the
17433 class-wide case, change the type of the object entity to the specific
17434 result subtype of the function, to avoid passing a class-wide object
17435 without explicit initialization to the back end.
17436 (Register_Interface_DT_Entry): Moved outside the body of
17437 Freeze_Subprogram because this routine is now public; it is called from
17438 Check_Dispatching_Overriding to handle late overriding of abstract
17439 interface primitives.
17440 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17441 adding an implicit access actual on a call to a build-in-place function.
17442 (Expand_Actuals): Test for an actual parameter that is a call to a
17443 build-in-place function and apply
17444 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17445 (Is_Build_In_Place_Function): New function to determine whether an
17446 entity is a function whose calls should be handled as build-in-place.
17447 (Is_Build_In_Place_Function_Call): New function to determine whether an
17448 expression is a function call that should handled as build-in-place.
17449 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17450 calls to build-in-place functions as the initialization of an allocator.
17451 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17452 handling calls to build-in-place functions in contexts that do not
17453 involve init of a separate object (for example, actuals of subprogram
17455 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17456 handling calls to build-in-place functions as the initialization of an
17457 object declaration.
17458 (Detect_Infinite_Recursion): Add explicit parameter Process to
17459 instantiation of Traverse_Body to avoid unreferenced warning.
17460 (Check_Overriding_Inherited_Interfaces): Removed.
17461 (Register_Interface_DT_Entry): Code cleanup.
17462 (Register_Predefined_DT_Entry): Code cleanup.
17463 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17464 inlined statements if within a transient scope.
17465 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17466 formal parameters with occurrences of actuals in inlined body, establish
17467 visibility on the proper view of the actual's subtype for the body's
17469 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17470 compatibility mode and we have an imported CPP subprogram because
17471 for now we assume that imported CPP primitives correspond with
17472 objects whose constructor is in the CPP side (and therefore we
17473 don't need to generate code to register them in the dispatch table).
17474 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17475 aligned selected component.
17476 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17477 the actual of an in-mode parameter is a type conversion.
17478 (Expand_Actuals): If the call does not come from source and the actual
17479 is potentially misaligned, let gigi handle it rather than rejecting the
17480 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17481 Class Wide types as returning by reference independantly of their
17482 controlled status since with HIE runtimes class wide types are not
17483 potentially controlled anymore.
17485 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17487 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17488 references that are private components of the protected object.
17489 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function

17498 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17499 initialization of Homonym_Len.
17500 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17501 names from fully qualified name. Fixes problem of duplicate
17502 external names differing only in the presence of such a block name.

17505 Pablo Oliveira <oliveira@adacore.com>
17507 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17508 subprogram Ids, even if they are not yet assigned.
17509 (Build_Subprogram_Id): It is now this function that will take care of
17510 calling Assign_Subprogram_Ids if necessary.
17511 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17512 should be done only once they are assigned.
17513 (Build_From_Any_Function, case of tagged types): Add missing call to
17515 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17516 type for an RACW type.
17517 (Add_RACW_Features): When processing an RACW declaration for which the
17518 designated type is already frozen, enforce E.2.2(14) rules immediately.
17519 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17520 special reordering of controlling formals.
17522 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17523 associated stub type for an RACW type.
17525 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17527 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17528 fixed-point operations in an integer context, i.e. as operands of a
17529 conversion to an integer type, indicate that result must be rounded.
17531 2006-10-31 Robert Dewar <dewar@adacore.com>
17533 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17534 cases, pass the encoding method, since it is now required by the run
17537 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17538 assumption that Str'First = 1.
17539 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17540 it on to the Value_Wide_Wide_Character call.
17541 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17542 properly handles a string of the form quote-encoded_wide_char-quote.
17544 * s-wchcnv.adb: Minor reformatting
17546 2006-10-31 Javier Miranda <miranda@adacore.com>
17548 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17549 run-time membership test to ensure that the constructed object
17550 implements the target abstract interface.
17552 2006-10-31 Robert Dewar <dewar@adacore.com>
17554 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17555 Machine_Attribute pragma internally to implement the user pragma.
17556 Add processing for pragma Interface so that it is now completely
17557 equivalent to pragma Import.
17559 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17560 so that it can be applied to all entities, including record components
17561 and enumeration literals.
17562 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17563 priority ranges are correct, verify compatibility against task
17564 dispatching and locking policies, and if everything is correct an entry
17565 is added to the table containing priority specific dispatching entries
17566 for this compilation unit.
17567 (Delay_Config_Pragma_Analyze): Delay processing
17568 Priority_Specific_Dispatching pragmas because when processing the
17569 pragma we need to access run-time data, such as the range of
17570 System.Any_Priority.
17571 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17572 Allow pragma Unreferenced as a context item
17573 Add pragma Preelaborable_Initialization
17574 (Analyze_Pragma, case Interface): Interface is extended so that it is
17575 now syntactically and semantically equivalent to Import.
17576 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17577 insertion characters.
17578 Add handling for Pragma_Wide_Character_Encoding
17579 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17580 never supercedes a real restriction, and that a real restriction
17581 always supercedes a warning.
17582 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17586 Ed Schonberg <schonberg@adacore.com>
17587 Robert Dewar <dewar@adacore.com>
17589 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17590 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17591 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17593 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17594 type of the function containing a return statement, because the
17595 Return_Type field was removed. We now use the Return_Applies_To field.
17597 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17598 (Build_Task_Image_Decl): If procedure is not called from an
17599 initialization procedure, indicate that function that builds task name
17600 uses the sec. stack. Otherwise the enclosing initialization procedure
17601 will carry the indication.
17602 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17603 N_Object_Declaration instead.
17604 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17605 conditional dead code killed, and change implementation accordingly.
17606 (Insert_Actions): Add N_Return_Object_Declaration case.
17607 Correct comment to mention N_Extension_Aggregate node.
17608 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17609 attempts to save information for global variables which cannot be
17611 (Get_Current_Value_Condition): Handle conditions the other way round
17612 (constant on left). Also handle right operand of AND and AND THEN
17613 (Set_Current_Value_Condition): Corresponding changes
17614 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17615 (Get_Current_Value_Condition): Handle simple boolean operands
17616 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17617 (Get_Current_Value_Condition): If the variable reference is within an
17618 if-statement, does not appear in the list of then_statments, and does
17619 not come from source, treat it as being at unknown location.
17620 (Get_Current_Value_Condition): Enhance to allow while statements to be
17621 processed as well as if statements.
17622 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17624 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17625 of loop. This is safe now that we fixed Kill_Current_Values.
17626 (OK_To_Do_Constant_Replacement): Check whether current scope is
17627 Standard, before examining outer scopes.
17629 2006-10-31 Vincent Celier <celier@adacore.com>
17631 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17632 When True, apply VMS treatment to children of packages A, G, I and S.

17642 (Freeze_Entity): Add check for Preelaborable_Initialization
17644 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17646 * g-expect.adb: Add Warnings (Off) to prevent new warning
17648 * lib-xref.adb: Add handling of Last_Assignment field
17649 (Generate_Reference): Centralize handling of pragma Obsolescent here
17650 (Generate_Reference): Accept an implicit reference generated for a
17651 default in an instance.
17652 (Generate_Reference): Accept a reference for a node that is not in the
17653 main unit, if it is the generic body corresponding to an subprogram
17656 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17658 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17660 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17662 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17663 use clauses, to avoid messages on packages used to qualify, and also
17664 to avoid messages from obsolescent units.
17665 (Warn_On_Useless_Assignments): Don't generate messages for imported
17666 and exported variables.
17667 (Warn_On_Useless_Assignments): New procedure
17668 (Output_Obsolescent_Entity_Warnings): New procedure
17669 (Check_Code_Statement): New procedure
17671 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17672 Change name Is_Ada_2005 to Is_Ada_2005_Only
17673 (Last_Assignment): New field for useless assignment warning
17675 2006-10-31 Olivier Hainque <hainque@adacore.com>
17677 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17678 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17680 2006-10-31 Bob Duff <duff@adacore.com>
17681 Robert Dewar <dewar@adacore.com>
17682 Ed Schonberg <schonberg@adacore.com>
17684 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17685 Ada 95 mode, because it violates the new rules for AI-318.
17687 * g-awk.ads: Use overloaded subprograms in every case where we used to
17688 have a default of Current_Session. This makes the code closer to be
17689 correct for both Ada 95 and 2005.
17691 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17692 code, relying on the fact that the compiler generates a warning
17693 instead of an error in -gnatg mode.
17695 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17696 E_Return_Statement entity kind.
17697 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17699 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17700 report an error if the reserved word abstract has been previously found.
17701 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17703 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17704 parenthesized range attribute usage
17705 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17707 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17708 in the syntax for extended_return_statement. This is not in the latest
17709 RM, but the ARG is expected to issue an AI allowing this.
17710 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17711 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17712 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17713 P_Return_Statement): Parse the new syntax for extended_return_statement.
17715 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17716 Output_End_Missing): Add error-recovery code for the new
17717 extended_return_statement syntax; that is, the new E_Return entry on
17720 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17721 limited to nonlimited, because otherwise we violate the new Ada 2005
17722 rules about returning limited types in function Create_AST_Handler in
17725 * sem.adb (Analyze): Add cases for new node kinds
17726 N_Extended_Return_Statement and N_Return_Object_Declaration.
17728 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17729 type is in the same category as type of context before applying check,
17730 to prevent anomalies in instantiations.
17731 (Resolve_Aggregate): Remove test for limited components in aggregates.
17732 It's unnecessary in Ada 95, because if it has limited components, then
17733 it must be limited. It's wrong in Ada 2005, because limited aggregates
17735 (Resolve_Record_Aggregate): Move check for limited types later, because
17736 OK_For_Limited_Init requires its argument to have been resolved.
17737 (Get_Value): When copying the component default expression for a
17738 defaulted association in an aggregate, use the sloc of the aggregate
17739 and not that of the original expression, to prevent spurious
17740 elaboration errors, when the expression includes function calls.
17741 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17742 were missing. We also didn't handle qualified expressions. Now also
17743 allow function calls. Use new common routine OK_For_Limited_Init.
17744 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17745 with space can upper case letter).
17747 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17748 Has_Static_Discriminants flag
17749 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17750 type with discriminants.
17751 (Process_Range_Expr_In_Decl): Do validity checks on range
17752 (Build_Discriminant_Constraints): Use updated form of
17753 Denotes_Discriminant.
17754 (Process_Subtype): If the subtype is a private subtype whose full view
17755 is a concurrent subtype, introduce an itype reference to prevent scope
17757 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17758 Record_Type_Declaration): The functionality of the subprograms
17759 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17760 is now performed by a single routine.
17761 (Build_Derived_Record_Type): If the type definition includes an explicit
17762 indication of limitedness, then the type must be marked as limited here
17763 to ensure that any access discriminants will not be treated as having
17764 a local anonymous access type.
17765 (Check_Abstract_Overriding): Issue a detailed error message when an
17766 abstract subprogram was not overridden due to incorrect mode of its
17768 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17769 synchronized private extension declarations. Verify that the ancestor is
17770 a limited or synchronized interface or in the generic case, the ancestor
17771 is a tagged limited type or synchronized interface and all progenitors
17772 are either limited or synchronized interfaces.
17773 Derived_Type_Declaration): Check for presence of private extension when
17774 dealing with synchronized formal derived types.
17775 Process_Full_View): Enchance the check done on the usage of "limited" by
17776 testing whether the private view is synchronized.
17777 Verify that a synchronized private view is completed by a protected or
17779 (OK_For_Limited_Init_In_05): New function.
17780 (Analyze_Object_Declaration): Move check for limited types later,
17781 because OK_For_Limited_Init requires its argument to have been resolved.
17782 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17783 in order to alleviate the upward compatibility introduced by AI-318.
17784 (Constrain_Corresponding_Record): If the constraint is for a component
17785 subtype, mark the itype as frozen, to avoid out-of-scope references to
17786 discriminants in the back-end.
17787 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17788 this subprogram against wrong sources.
17789 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17790 discriminant of limited type completed with a protected type, when the
17791 discriminant is used to constrain a private component of the type, and
17792 expansion is disabled.
17793 (Find_Type_Of_Object): Do not treat a return subtype that is an
17794 anonymous subtype as a local_anonymous_type, because its accessibility
17795 level is the return type of the enclosing function.
17796 (Check_Initialization): In -gnatg mode, turn the error "cannot
17797 initialize entities of limited type" into a warning.
17798 (OK_For_Limited_Init): Return true for generated nodes, since it
17799 sometimes violates the legality rules.
17800 (Make_Incomplete_Declaration): If the type for which an incomplete
17801 declaration is created happens to be the currently visible entity,
17802 preserve the homonym chain when removing it from visibility.
17803 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17804 inherited subprograms.
17805 (Access_Definition): If this is an access to function that is the return
17806 type of an access_to_function definition, context is a type declaration
17807 and the scope of the anonymous type is the current one.
17808 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17809 incomplete subtype to the set of private dependents of the original
17811 (Constrain_Discriminated_Type): Emit an error message whenever an
17812 incomplete subtype is being constrained.
17813 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17814 corresponding subtype of the full view of the original incomplete type.
17815 (Check_Incomplete): Properly detect invalid usage of incomplete types
17818 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17820 * g-catiio.ads, g-catiio.adb (Value): New function.
17821 Given an input String, try and parse a valid Time value.
17823 2006-10-31 Vincent Celier <celier@adacore.com>

17829 Robert Dewar <dewar@adacore.com>
17831 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17832 handling executable extension manually and duplicating code.
17834 * make.adb: Implement new -S switch
17835 (Gnatmake): Use new function Osint.Executable_Name instead
17836 of handling executable extension manually.
17838 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17839 is specified, the executable name ends with this suffix.
17840 Take advantage of Osint.Executable_Name instead of duplicating code.
17842 * switch-m.adb: Recognize new gnatmake -S switch
17844 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17846 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17849 * makeusg.adb: Add line for gnatmake -S switch
17851 2006-10-31 Vincent Celier <celier@adacore.com>
17853 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17854 call it with -static-libgcc, as there are some platforms, such as
17855 Darwin, where one of these two switches is compulsory to link.
17857 2006-10-31 Vincent Celier <celier@adacore.com>
17859 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17860 instead of ADA_PROJECT_PATH, for the project path.
17861 (Gnatls): When displaying the project path directories, use host dir
17864 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17865 names in the project path, as absolute paths may correspond to
17866 multi-valued VMS logical names.

17873 (Change_Dir): Remove, no longer used
17874 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17875 on Windows. Get it calling Get_Current_Dir.

17895 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
17897 2006-10-31 Robert Dewar <dewar@adacore.com>
17899 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17901 (Layout_Variant_Record): Retrieve the discriminants from the entity
17902 rather than from the type definition, because in the case of a full
17903 type for a private type we need to take the discriminants from the
17905 (Layout_Component_List): When applying the Max operator to variants with
17906 a nonstatic size, check whether either operand is static and scale that
17907 operand from bits to storage units before applying Max.
17908 (Layout_Type): In VMS, if a C-convention access type has no explicit
17909 size clause (and does not inherit one in the case of a derived type),
17910 then the size is reset to 32 from 64.
17912 2006-10-31 Vincent Celier <celier@adacore.com>
17914 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17915 its file has already been loaded, according to the unit being loaded,
17916 not to the current value of Multiple_Unit_Index.
17918 2006-10-31 Thomas Quinot <quinot@adacore.com>
17919 Eric Botcazou <ebotcazou@adacore.com>
17920 Arnaud Charlet <charlet@adacore.com>
17922 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
17923 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
17925 (a-except.o): Pass it to the compiler.
17926 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

17947 (Initialize): Remove, no longer used
17948 (Ar): If Ar_Exec is null, get the location of the archive builder and,

17954 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17956 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17957 Process_Body_Clauses): If the context of a body includes a use clause
17958 for P.Q then a with_clause for P in the same body is not redundant,
17959 even if the spec also has a with_clause on P.
17960 Add missing continuation mark to error msg
17961 (Build_Limited_Views): A limited view of a type is tagged if its
17962 declaration includes a record extension.
17963 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17964 node, even if the subunit has errors. This avoids malfunction by
17965 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17966 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17967 generation of obsolescent messages for with statements (cannot do
17968 this too early, or we cannot implement avoiding the messages in the
17969 case of obsolescent units withing obsolescent units).
17970 (Install_Siblings): If the with_clause is on a remote descendant of
17971 an ancestor of the current compilation unit, find whether there is
17972 a sibling child unit that is immediately visible.
17973 (Remove_Private_With_Clauses): New procedure, invoked after completing
17974 the analysis of the private part of a nested package, to remove from
17975 visibility the private with_clauses of the enclosing package
17977 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17978 now centralized in Generate_Reference.
17979 (Install_Limited_Context_Clauses): Remove superfluous error
17980 message associated with unlimited view visible through use
17981 and renamings. In addition, at the point in which the error
17982 is reported, we add the backslash to the text of the error
17983 to ensure that it is reported as a single error message.
17984 Use new // insertion for some continuation messages
17985 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17986 to create implicit with_clause for parent unit mentioned in original
17987 limited_with_clause.
17988 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17989 unit is a child unit. For ASIS queries.
17990 (Analyze_Subunit): If the subunit appears within a child unit, make all
17991 ancestor child units directly visible again.

18004 P_Interface_Type_Definition.
18005 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18006 a formal object declaration with an access definition or a subtype mark
18007 with a null exclusion.
18008 (P_Generic_Association): Handle association with box, and others_choice
18009 with box, to support Ada 2005 partially parametrized formal packages.
18011 2006-10-31 Robert Dewar <dewar@adacore.com>
18012 Javier Miranda <miranda@adacore.com>
18014 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18015 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18016 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18017 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18018 private extensions.
18019 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18020 to P_Interface_Type_Definition.
18021 (P_Interface_Type_Definition): Addition of one formal to report an error
18022 if the reserved word abstract has been previously found.
18023 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18024 object renaming declaration with an access definition or subtype mark
18025 with a possible null exclusion.

18044 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18047 2006-10-31 Vincent Celier <celier@adacore.com>
18049 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18050 on VMS, change "__" to '.' before checking the name.
18051 (Record_Ada_Source): Always add the source file name in the list of
18052 of sources, even if it is not the first time, as it is for another
18054 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18055 dot, instead of replacing only the first '_'.
18057 * prj-part.adb (Parse): Convert project file path to canonical form
18059 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18060 extended, the project id of the project extending it is recorded in its
18061 data, even when it has already been processed as an imported project.
18063 2006-10-31 Robert Dewar <dewar@adacore.com>
18065 * repinfo.adb (List_Entities): Don't list entities from renaming
18068 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18069 Robert Dewar <dewar@adacore.com>
18071 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18072 only a restriction warning is active for the given restriction. This is
18073 desirable because we do not want to modify code in the case where only
18075 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18076 causes overriding of real restrictions.
18077 Take advantage of new No_Restrictions constant.
18079 * raise.h: (__gnat_set_globals): Change profile.
18081 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18083 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18086 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18087 Move all the entities in obsolete package System.PolyORB_Interface to
18088 System.Partition_Interface.
18089 (RE_Storage_Size): New function in System.Tasking.

18103 Javier Miranda <miranda@adacore.com>
18104 Gary Dismukes <dismukes@adacore.com>
18106 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18107 properly an attempt to apply Unchecked_Access to a protected operation.
18108 (OK_Self_Reference): New subprogram to check the legality of an access
18109 attribute whose prefix is the type of an enclosing aggregate.
18110 Generalizes previous mechanism to handle attribute references nested
18111 arbitrarily deep within the aggregate.
18112 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18113 can appear in an aggregate if this is a default-initialized aggregate
18114 for a self-referential type.
18115 (Resolve_Attribute, case Access): Ditto.
18116 Add support for new implementation defined attribute Stub_Type.
18117 (Eval_Attribute, case Attribute_Stub_Type): New case.
18118 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18119 (Stream_Attribute_Available): Implement using new subprogram from
18120 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18121 Has_Specified_Stream_Attribute flag.
18122 Disallow Storage_Size and Storage_Pool for access to subprogram
18123 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18124 access types of return subtypes in extended return statements. Remove
18125 accessibility checks on anonymous access types when Unchecked_Access is
18127 (Analyze_Attribute): Add support for the use of 'Class to convert
18128 a class-wide interface to a tagged type.
18129 Add support for the attribute Priority.
18130 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18131 whether the designated type is discriminated with a constrained partial
18132 view and require static matching in that case.
18133 Add local variable Des_Btyp. The Designated_Type
18134 of an access to incomplete subtype is either its non-limited view if
18135 coming from a limited with or its etype if regular incomplete subtype.
18137 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18138 Fix predicate to identify and allow cases of (expander-generated)
18139 references to tag of designated object of a RACW.
18140 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18141 non-static, and therefore cannot appear as a primary in a preelaborable
18143 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18144 Has_Read_Write_Attributes.
18145 (Has_Read_Write_Attributes): Reimplement in termes of
18146 Has_Stream_Attribute_Definition.
18147 (Missing_Read_Write_Attributes): When checking component types in a
18148 record, unconditionally call Missing_Read_Write_Attributes recursively
18149 (remove guard checking for Is_Record_Type / Is_Access_Type).
18151 2006-10-31 Robert Dewar <dewar@adacore.com>
18153 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18154 useless assignments here and conditionalize it on absence of exception
18156 (Analyze_Exception_Handlers): Small code reorganization of error
18157 detection code, for new handling of formal packages.
18159 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18160 Hristian Kirtchev <kirtchev@adacore.com>
18162 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18163 that has been constant-folded, preserve information of original tree,
18165 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18166 generated private extension declaration if the formal derived type is
18167 synchronized. Carry synchronized present over to the generated private
18169 (Validate_Derived_Type_Instance): Ensure that the actual of a
18170 synchronized formal derived type is a synchronized tagged type.
18171 (Instantiate_Formal_Package): When creating the instantiation used to
18172 validate the actual package of a formal declared without a box, check
18173 whether the formal itself depends on a prior actual.
18174 (Instantiate_Formal_Subprogram): Create new entities for the defining
18175 identifiers of the formals in the renaming declaration, for ASIS use.
18176 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18177 a renaming declaration or a subtype declaration for an actual in an
18178 instance, capture location information of declaration in generic, for
18180 (Instantiate_Formal_Package): Add comments on needed additional tests.
18181 AI-317 (partial parametrization) is fully implemented.
18182 (Validate_Private_Type_Instance): Add check for actual which
18183 must have preelaborable initialization
18184 Use new // insertion for some continuation messages
18185 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18186 Default_Expression. Add type retrieval when the declaration has an
18187 access definition. Update premature usage of incomplete type check.
18188 (Check_Access_Definition): New subsidiary routine. Check whether the
18189 current compilation version is Ada 05 and the supplied node has an
18191 (Instantiate object): Alphabetize local variables. Handle the creation
18192 of new renaming declarations with respect to the kind of definition
18193 used - either an access definition or a subtype mark. Guard against
18194 unnecessary error message in the context of anonymous access types after
18195 they have been resolved. Add check for required null exclusion in a
18196 formal object declaration.
18197 (Switch_View): A private subtype of a non-private type needs to be
18198 switched (the base type can have been switched without its private
18199 dependents because of the last branch of Check_Private_View.
18200 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18202 (Instantiate_Type): Emit an error message whenever a class-wide type of
18203 a tagged incomplete type is used as a generic actual.
18204 (Find_Actual_Type): Extend routine to handle a component type in a child
18205 unit that is imported from a formal package in a parent.
18206 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18207 agree on constrainedness, rather than checking against ultimate ancestor
18208 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18209 generic body, for navigation purposes.
18211 2006-10-31 Robert Dewar <dewar@adacore.com>
18212 Thomas Quinot <quinot@adacore.com>
18214 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18216 (New_Stream_Subprogram): When processing an attribute definition clause
18217 for a stream-oriented subprogram, record an entity node occurring at
18218 the point of clause to use for checking the visibility of the clause,
18219 as defined by 8.3(23) as amended by AI-195.
18220 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18221 New_Stream_Function and New_Stream_Procedure.
18222 (New_Stream_Function, New_Stream_Procedure): Removed.
18223 (Analyze_Attribute_Definition_Clause, case Address): Check new
18224 Alignment_Check check

18227 Javier Miranda <miranda@adacore.com>
18228 Robert Dewar <dewar@adacore.com>
18230 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18231 generate the same errors compiling under -gnatc.
18232 (Try_Object_Operation): If no candidate interpretation succeeds, but
18233 there is at least one primitive operation with the right name, report
18234 error in call rather than on a malformed selected component.
18235 (Analyze_Selected_Component): If the prefix is an incomplete type from
18236 a limited view, and the full view is available, use the full view to
18237 determine whether this is a prefixed call to a primitive operation.
18238 (Operator_Check): Verify that a candidate interpretation is a binary
18239 operation before checking the type of its second formal.
18240 (Analyze_Call): Add additional warnings for function call contexts not
18242 (Analyze_Allocator): Move the check for "initialization not allowed for
18243 limited types" after analyzing the expression. This is necessary,
18244 because OK_For_Limited_Init looks at the structure of the expression.
18245 Before analysis, we don't necessarily know what sort of expression it
18246 is. For example, we don't know whether F(X) is a function call or an
18247 indexed component; the former is legal in Ada 2005; the latter is not.
18248 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18249 were missing. We also didn't handle qualified expressions. Now also
18250 allow function calls. Use new common routine OK_For_Limited_Init.
18251 (Analyze_Type_Conversion): Do not perform some legality checks in an
18252 instance, because the error message will be redundant or spurious.
18253 (Analyze_Overloaded_Selected_Component): Do not do style check when
18254 setting an entity, since we do not know it is the right entity yet.
18255 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18256 (Analyze_Overloaded_Selected_Component): Same change
18257 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18258 since regular incomplete subtypes are transformed into corresponding
18259 subtypes of their full views.
18260 (Complete_Object_Operation): Treat name of transformed subprogram call
18261 as coming from source, for browsing purposes.
18262 (Try_Primitive_Operation): If formal is an access parameter, compare
18263 with base type of object to determine whether it is a primitive
18265 (Operator_Check): If no interpretation of the operator matches, check
18266 whether a use clause on any candidate might make the operation legal.
18267 (Try_Class_Wide_Operation): Check whether the first parameter is an
18268 access type whose designated type is class-wide.

18271 Ed Schonberg <schonberg@adacore.com>
18272 Gary Dismukes <dismukes@adacore.com>
18274 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18275 warn on infinite loops.
18276 Add \\ to some continuation messages
18277 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18278 (Process_Bounds): If the bounds are integer literals that result from
18279 constant-folding, and they carry a user-defined type, preserve that type
18280 rather than treating this as an integer range.
18281 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18282 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18283 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18284 left hand side of assignment.
18285 (Analyze_Assignment): Add suport to manage assigments to the attribute
18286 priority of a protected object.
18287 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18288 not just identifiers.
18289 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18290 or AND THEN for possible tracking.
18291 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18292 case of while loops so we can track values in the loop body.
18294 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18295 Hristian Kirtchev <kirtchev@adacore.com>
18296 Bob Duff <duff@adacore.com>
18298 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18299 procedure cannot be a protected operation (it is a basic_declaration,
18300 not a subprogram_declaration).
18301 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18302 Subp. Add logic for entry processing.
18303 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18304 Determine whether an entry or subprogram of a protected or task type
18305 override an inherited primitive of an implemented interface.
18306 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18307 Update the actual used in calls to Check_Overriding_Indicator.
18308 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18309 generate the proper reference to the parent unit, for cross-reference.
18310 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18312 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18313 (Add_Extra_Formal): Revise procedure to allow passing in associated
18314 entity, scope, and name suffix, and handle setting of the new
18315 Extra_Formals field.
18316 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18317 pass new parameters. Add support for adding the new extra access formal
18318 for functions whose calls are treated as build-in-place.
18319 (Analyze_A_Return_Statement): Correct casing in error message.
18320 Move Pop_Scope to after Analyze_Function_Return, because an extended
18321 return statement really is a full-fledged scope. Otherwise, visibility
18322 doesn't work right. Correct use of "\" for continuation messages.
18323 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18324 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18325 the node doesn't get properly marked as analyzed.
18326 (Analyze_Subprogram_Body): If subprogram is a function that returns
18327 an anonymous access type that denotes a task, build a Master Entity
18329 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18330 proper usage of null exclusion in a result definition.
18331 (Process_Formals): Code cleanup and new error message.

18334 (Conforming_Types): Handle conformance between [sub]types and itypes
18335 generated for entities that have null exclusions applied to them.
18336 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18337 base type is an access subtype. This case arrises with null exclusions.
18338 (New_Overloaded_Entity): Do not remove the overriden entity from the
18339 homonym chain if it corresponds with an abstract interface primitive.
18340 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18341 call to the synthesized predicate Is_Incomplete_Type.
18342 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18344 (Analyze_Subprogram_Declaration): Check that abstract interface
18345 primitives are abstract or null.
18346 (Analyze_Subprogram_Specification): Remove previous check for abstract
18347 interfaces because it was not complete.
18348 (Has_Interface_Formals): Removed.

18353 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18354 of Analyze_Package_Body, to create Itype references for anonymous
18355 access types created in the package declaration, whose designated types
18356 may have only a limited view.
18357 (Analyze_Package_Specification): For the private part of a nested
18358 package, install private_with_clauses of enclosing compilation unit if
18359 we are in its visible part.
18360 (Declare_Inherited_Private_Subprograms): Complete barrier
18361 to ensure that the primitive operation has an alias to some parent
18362 primitive. This is now required because, after the changes done for the
18363 implementation of abstract interfaces, the contents of the list of
18364 primitives has entities whose alias attribute references entities of
18365 such list of primitives.
18366 (Analyze_Package_Specification): Simplify code that handles parent units
18367 of instances and formal packages.
18368 (Uninstall_Declarations): Check the convention consistency among
18369 primitive overriding operations of a tagged record type.

18383 as potentially use-visible.
18384 (Find_Type): Handle the case of an attribute reference for
18385 implementation defined attribute Stub_Type (simply let the analysis of
18386 the attribute reference rewrite it).

18388 type that appears in a Use_Type clause.
18389 (Analyze_Object_Renaming): Add support for renaming of the Priority

18394 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18395 in a formal object declaration or in a subtype declaration.
18396 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18397 (Check_Null_Exclusion): New local routine to
18398 Analyze_Subprogram_Renaming. Check whether the formals and return
18399 profile of a renamed subprogram have required null exclusions when
18400 their counterparts of the renaming already impose them.
18401 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18402 Determine whether an entity is inside a generic scope.
18403 (In_Open_Scope): First pass of documentation update.
18404 (Find_Expanded_Name): Add support for shadow entities associated with
18405 limited withed packages. This is required to handle nested packages.
18406 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18407 that makes a renaming of a limited withed package illegal.

18410 Ed Schonberg <schonberg@adacore.com>
18412 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18413 Check_Overriding_Indicator.
18414 (Analyze_Task_Definition): Ditto.
18415 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18416 (Check_Overriding_Indicator): To find overridden interface operation,
18417 examine only homonyms that have an explicit subprogram declaration, not
18418 inherited operations created by an unrelated type derivation.
18419 (Check_Overriding_Indicator): When checking for the presence of "null"
18420 in a procedure, ensure that the queried node is a procedure
18422 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18423 type when the formal is an access to variable.
18424 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18425 (Analyze_Task_Type): Same addition
18426 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18427 provide navigation capabilities for entries.

18434 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18435 inherited from an interface ancestor by another interface in the
18436 context of an instance as 'late'.
18437 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18438 of a call to a function that dispatches on access result.
18439 (Check_Dispatching_Operation): In case of late overriding of a primitive
18440 that covers abstract interface subprograms we register it in all the
18441 secondary dispatch tables associated with abstract interfaces.
18442 (Check_Dispatching_Call): Add check that a dispatching call is not made
18443 to a function with a controlling result of a limited type. This is a
18444 current implementation restriction.
18445 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18446 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18447 argument is an interface type that is a generic formal.
18448 (Is_Interface_Subprogram): Removed.
18449 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18450 operation, check the formals to handle the case in which it is
18451 associated with an abstract interface type.
18453 2006-10-31 Robert Dewar <dewar@adacore.com>
18454 Ed Schonberg <schonberg@adacore.com>

18468 Hristian Kirtchev <kirtchev@adacore.com>
18469 Javier Miranda <miranda@adacore.com>
18471 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18472 subprogram type to provide better diagnostics in case of ambiguity.
18473 (Covers): Handle coverage of formal and actual anonymous access types in
18474 the context of generic instantiation.
18475 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18476 abstract interface types; this is required to handle concurrent types
18477 with discriminants and abstract interface types.

18491 Add missing continuation marks in error msgs
18492 (Unqualify): New function for removing zero or more levels of
18493 qualification from an expression. There are numerous places where this
18494 ought to be used, but we currently only deal properly with zero or one
18496 (In_Instance); The analysis of the actuals in the instantiation of a
18497 child unit is not within an instantiation, even though the parent
18498 instance is on the scope stack.

18501 (Check_Obsolescent): Removed
18502 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18520 (Has_Compatible_Alignment): New function
18521 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18522 objects to handle the Ada 2005 case, where aliasedness no longer implies

18580 (N_Extended_Return_Statement): New node for extended_return_statement
18582 (N_Return_Object_Declaration): New node for part of

18608 N_Extended_Return_Statement. Alphabetize the cases.
18609 Add cases for new nodes N_Extended_Return_Statement and
18610 N_Return_Object_Declaration. The code is not yet written.

18664 2006-10-31 Olivier Hainque <hainque@adacore.com>
18666 * s-stchop.ads: make this unit preelaborate. This is desirable in

18668 is itself preelaborate.
18670 * s-stchop-vxworks.adb (Set_Stack_Info, Task_Descriptor type): Add
18671 Td_Events component.

18756 * a-rttiev.ads, a-rttiev.adb:
18757 This is a significant redesign primarily for the sake of automatic
18758 timer task termination but also to fix a design flaw.
18759 Therefore we are now using an RTS lock, instead of a protected
18760 object, to provide mutual exclusion to the queue of pending events
18761 and the type Timing_Event is no longer a protected type.

19609 other basic tools. The full version that includes the Ada 2005 stuff
19610 is in separate files a-except-2005.ads/adb. The reason is that we do
19611 not want to cause bootstrap problems with compilers not recognizing

19935 -d is now controlling the primary stack size when its value is a
19936 positive. Also add checks against invalid values, and support for kb,
19937 mb. Ditto for -D switch.

19940 Serguei Rybin <rybin@adacore.com>
19942 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19943 save/restore routines.
19944 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

19946 Since we are changing the tree format anyway, also get rid of the
19947 junk obsolete Immediate_Errors flag.
19948 (Tree_Read): Change the way of reading Tree_Version_String - now we
19949 read the version string from the tree even if its length is not the
19950 same as the length of the version string computed from Gnatvsn.
19951 (Search_Directory_Present): New Boolean flag for the compiler.
19952 Define Tree_Version_String as a dynamic string.

19977 (Is_Limited_Type): A type whose ancestor is an interface is limited if
19978 explicitly declared limited.

19982 whose ancestor has discriminants.
19984 * exp_ch2.adb: Update status of new Is_Known_Null flag
19986 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

20009 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20010 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20011 does not exist in the Ada RM.
20012 (Compatible_Int_Bounds): Determine whether two integer range bounds
20013 are of equal length and have the same start and end values.
20014 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20015 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20016 aggregate when it is part of an object declaration.
20017 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20018 constrains discriminants of its parent, add explicitly the discriminant
20019 constraints of the ancestor by retrieving them from the
20020 stored_constraint of the parent.
20022 2006-02-13 Robert Dewar <dewar@adacore.com>
20024 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20025 attribute Mechanism_Code is applied to renamed subprogram, modify
20026 prefix to point to base subprogram.
20027 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20029 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20030 renamed subprograms so that the front-end must replace the prefix

20034 Gary Dismukes <dismukes@adacore.com>
20036 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20037 availability of RE_Interface_Tag.
20038 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20039 (Freeze_Record_Type): Do not generate the tables associated with
20040 timed and conditional dispatching calls through synchronized
20041 interfaces if compiling under No_Dispatching_Calls restriction.
20042 When compiling for Ada 2005, for a nonabstract
20043 type with a null extension, call Make_Controlling_Function_Wrappers
20044 and insert the wrapper function declarations and bodies (the latter
20045 being appended as freeze actions).
20046 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20047 predefined primitives associated with timed and conditional
20048 dispatching calls through synchronized interfaces if we are
20049 compiling under No_Dispatching_Calls.
20050 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20051 service is available before generating a call.
20052 (Make_Controlling_Function_Wrappers): New procedure.
20053 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20054 access-to-limited-interfaces because they can be used to reference
20055 tasks that implement such limited interface.
20056 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20057 procedure spec and body of the Offset_To_Top function that is generated
20058 when the parent of a type with discriminants has secondary dispatch
20060 (Init_Secondary_Tags): Handle the case in which the parent of the type
20061 containing secondary dispatch tables has discriminants to generate the
20062 correct arguments to call Set_Offset_To_Top.
20063 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20065 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20066 Add Wide_[Wide_]Expanded_Name.
20067 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20068 the same functionality of Get_Prim_Op_Address but applied to predefined
20069 primitive operations because the pointers to the predefined primitives
20070 are now saved in a separate table.
20071 (Parent_Size): Modified to get access to the separate table of primitive
20072 operations or the parent type.
20073 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20074 functionality of Set_Prim_Op_Address but applied to predefined primitive
20076 (Set_Signature): New subprogram used to store the signature of a DT.
20077 (Displace): If the Offset_To_Top value is not static then call the
20078 function generated by the expander to get such value; otherwise use
20079 the value stored in the table of interfaces.
20080 (Offset_To_Top): The type of the actual has been changed to Address to
20081 give the correct support to tagged types with discriminants. In this
20082 case this value is stored just immediately after the tag field.
20083 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20084 offset_to_top value is static and hence pass this value to the run-time
20085 to store it in the table of interfaces, or else if this value is dynamic
20086 and then pass to the run-time the address of a function that is
20087 generated by the expander to provide this value for each object of the
20090 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20091 (Default_Prim_Op_Count): New entity

20097 Ed Schonberg <schonberg@adacore.com>
20099 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20100 Make_Adjust_Call done for a newly-allocated object.
20102 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20103 in a subprogram are wrapped in a cleanup block, indicate that the
20104 subprogram contains an inner block with an exception handler.
20105 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20106 Adjust call is for a newly-allocated object. In that case we must not
20107 assume that the finalization list chain pointers are correct (since they
20108 come from a bit-for-bit copy of the original object's pointers) so if
20109 the attach level would otherwise be zero (no change), we set it to 4
20110 instead to cause the pointers to be reset to null.
20112 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20113 reset chain pointers to null.
20115 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20117 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20118 string, and the context requires a loop for the assignment (e.g.
20119 because the left-hand side is packed), generate a unique name for the
20120 temporary that holds the string, to prevent spurious name clashes.
20122 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20123 Javier Miranda <miranda@adacore.com>
20124 Robert Dewar <dewar@adacore.com>
20125 Gary Dismukes <dismukes@adacore.com>
20127 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20128 return unconstrained arrays.
20130 (Expand_Call): An indirect call through an access parameter of a
20131 protected operation is not a protected call.
20132 Add circuit to raise CE in Ada 2005 mode following call
20133 to Raise_Exception.
20134 (Register_DT_Entry): Do nothing if
20135 the run-time does not give support to abstract interfaces.
20136 (Freeze_Subprogram): In case of dispatching operations, do not generate
20137 code to register the operation in the dispatch table if the source
20138 is compiled with No_Dispatching_Calls.
20139 (Register_Predefined_DT_Entry): Generate code that calls the new
20140 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20141 Set_Prim_Op_Address.
20143 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20144 on array assignments if the right-hand side is a function call that has
20145 been inlined. Check is performed on the assignment in the block.
20146 (Process_Bounds): If bounds and range are overloaded, apply preference
20147 rule for root operations to disambiguate, and diagnose true ambiguity.
20148 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20149 a tag-indeterminate right-hand side even when Expander_Active is True.
20150 Needed to ensure that dispatching calls to T'Input are allowed and
20151 get the tag of the target class-wide object.
20153 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20154 an inherited primitive operation that already overrides several
20155 abstract interface primitives. For transitivity, the new entity must
20156 also override all the abstract interface primitives covered by the
20157 inherited overriden primitive.
20158 Emit warning if new entity differs from homograph in same scope only in
20159 that one has an access parameter and the other one has a parameter of
20160 a general access type with the same designated type, at the same
20161 position in the signature.
20162 (Make_Inequality_Operator): Use source locations of parameters and
20163 subtype marks from corresponding equality operator when creating the
20164 tree structure for the implicit declaration of "/=". This does not
20165 change anything in behaviour except that the decoration of the
20166 components of the subtree created for "/=" allows ASIS to get the
20167 string images of the corresponding identifiers.
20168 (Analyze_Return_Statement): Remove '!' in warning message.
20169 (Check_Statement_Sequence): Likewise.
20170 (Analyze_Subprogram_Body): For an access parameter whose designated type
20171 is an incomplete type imported through a limited_with clause, use the
20172 type of the corresponding formal in the body.
20173 (Check_Returns): Implicit return in No_Return procedure now raises
20174 Program_Error with a compile time warning, instead of beging illegal.
20175 (Has_Single_Return): Function returning unconstrained type cannot be
20176 inlined if expression in unique return statement is not an identifier.
20177 (Build_Body_To_Inline): It is possible to inline a function call that
20178 returns an unconstrained type if all return statements in the function
20179 return the same local variable. Subsidiary procedure Has_Single_Return
20180 verifies that the body conforms to this restriction.
20182 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20183 same type, and one of them is of an anonymous access type, convert
20184 the other operand to it, so that this is a valid binary operation for
20186 (Resolve_Type_Conversion): Handle subtypes of protected types and
20187 task types when accessing to the corresponding record type.
20188 (Resolve_Allocator): Add '\' in 2-line warning message.
20189 Remove '!' in warning message.
20190 (Resolve_Call): Add '\' in 2-line warning message.
20191 (Valid_Conversion): Likewise.
20192 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20193 resulting type may be an access type with an implicit dereference.
20194 Obtain the proper component from the designated type.
20195 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20196 given by an expanded name with prefix Standard, when the operands are
20197 of an anonymous access type.
20198 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20199 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20200 prefix of the expression is not of an incomplete type. Allows full
20201 diagnoses of all semantic errors.
20202 (Resolve_Actuals): If the actual is an allocator whose directly
20203 designated type is a class-wide interface we build an anonymous
20204 access type to use it as the type of the allocator. Later, when
20205 the subprogram call is expanded, if the interface has a secondary
20206 dispatch table the expander will add a type conversion to force
20207 the displacement of the pointer.
20208 (Resolve_Call): If a function that returns an unconstrained type is
20209 marked Inlined_Always and inlined, the call will be inlined and does
20210 not require the creation of a transient scope.
20211 (Check_Direct_Boolean_Op): Removed
20212 (Resolve_Comparison_Op): Remove call to above
20213 (Resolve_Equality_Op): Remove call to above
20214 (Resolve_Logical_Op): Inline above, since this is only call.
20215 (Valid_Conversion): Handle properly conversions between arrays of
20216 convertible anonymous access types.
20219 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20220 the literal in an unchecked conversion, because GCC 4.x needs a static
20221 value for a string bound.
20223 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20224 Hristian Kirtchev <kirtchev@adacore.com>
20226 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20227 components of the corresponding record, take into account component
20228 definitions that are access definitions.
20229 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20230 procedure is not considered a dispatching call and will be expanded
20233 2006-02-13 Javier Miranda <miranda@adacore.com>
20235 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20236 controlling argument of the dispatching call is an abstract interface
20237 class-wide type then we use it directly.
20238 Check No_Dispatching_Calls restriction.
20239 (Default_Prim_Op_Position): Remove the code that looks for the last
20240 entity in the list of aliased subprograms. This code was wrong in
20242 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20243 when the source is compiled with the No_Dispatching_Calls restriction.
20244 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20245 if we are compiling with restriction No_Dispatching_Calls.
20246 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20247 subprograms if we are compiling under No_Dispatching_Calls restriction.
20248 (Make_DT): Generate a dispatch table with a single dummy entry if
20249 we are compiling with the No_Dispatching_Calls restriction. In
20250 addition, in this case we don't generate code that calls to the
20251 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20252 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20253 of this subprogram if compiling with the No_Dispatching_Calls
20255 (Expand_Type_Conversion): Instead of using the actual parameter,
20256 the argument passed as parameter to the conversion function was
20257 erroneously referenced by the expander.
20258 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20259 Set_Predefined_Primitive_Op_Address and Set_Signature.
20260 (Expand_Dispatching_Call): Generate call to
20261 Get_Predefined_Prim_Op_Address for predefined primitives.
20262 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20263 predefined primitives.
20264 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20265 primitives we reserve one dummy entry to ensure that the tag does not
20266 point to some memory that is associated with some other object. In
20267 addition, remove all the old code that generated the assignments
20268 associated with the signature of the dispatch table and replace them
20269 by a call to the new subprogram Set_Signature.
20270 (Set_All_DT_Position): Change the algorithm because now we have a
20271 separate dispatch table associated with predefined primitive operations.
20272 (Expand_Interface_Conversion): In case of non-static offset_to_top
20273 add explicit dereference to get access to the object after the call
20274 to displace the pointer to the object.
20275 (Expand_Interface_Thunk): Modify the generation of the actual used
20276 in the calls to the run-time function Offset_To_Top to fulfil its
20278 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

20282 * exp_dist.adb (Copy_Specification): For access parameters, copy
20283 Null_Exclusion flag, which will have been set for stream subprograms
20286 2006-02-13 Pascal Obry <obry@adacore.com>
20288 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20289 previous implementation was using the C runtime spawnve routine but
20290 the corresponding wait was using directly the Win32 API. This was
20291 causing some times a lock when waiting for an event using
20292 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20293 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20294 API fixes this problem.
20296 2006-02-13 Robert Dewar <dewar@adacore.com>
20298 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20306 array reference that is an explicit dereference, mark the converted
20307 (packed) array reference as analyzed to prevent a forthcoming
20308 reanalysis from resetting its type to the original (non-packed) array
20311 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20312 Javier Miranda <miranda@adacore.com>
20313 Eric Botcazou <ebotcazou@adacore.com>
20315 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20316 Is_Predefined_Primitive_Operation): When
20317 searching for the predefined equality operator, verify that operands
20318 have the same type.
20319 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20320 for the last entity in the list of aliased subprograms. This code
20321 was wrong in case of renamings.
20322 (Set_Renamed_Subprogram): New procedure
20323 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20324 Exp_Type constant computed when entering this subprogram.
20325 (Known_Null): New function
20326 (OK_To_Do_Constant_Replacement): New function
20327 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20328 (Side_Effect_Free): An attribute reference 'Input is not free of
20329 side effect, unlike other attributes that are functions. (from code
20331 (Remove_Side_Effects): Expressions that involve packed arrays or records
20332 are copied at the point of reference, and therefore must be marked as
20333 renamings of objects.
20334 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20335 not a dispatching operation.
20338 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20339 elementary types in all cases.
20341 2006-02-13 Javier Miranda <miranda@adacore.com>

20344 task types when accessing to the corresponding record type.
20345 Remove '!' in warning message.
20347 2006-02-13 Olivier Hainque <hainque@adacore.com>
20349 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20350 to avoid useless and space inefficient overalignments on targets where
20351 Max_Alignment is larger than 16.
20353 2006-02-13 Pascal Obry <obry@adacore.com>
20355 * g-catiio.adb (Sec_Number): New type used to compute the number of
20356 seconds since 1-1-1970.
20357 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20358 negative numbers (years, months...) it is better to have a Natural here.
20360 (Image) [Number]: Change parameter from Long_Integer to Number.
20361 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20362 overflow for dates past year 2038.
20364 2006-02-13 Matthew Heaney <heaney@adacore.com>
20366 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20369 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20371 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20373 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20374 finalization can occur normally.
20376 2006-02-13 Vincent Celier <celier@adacore.com>
20378 * gnatcmd.adb (Rules_Switches): New table
20379 (Add_To_Rules_Switches): New procedure
20380 (GNATCmd): For command CHECK, put all options following "-rules" in the
20381 Rules_Switches table. Append these -rules switches after the -cargs
20384 2006-02-13 Robert Dewar <dewar@adacore.com>
20386 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20387 These two cases were generating incorrect output, and if this unit
20388 was built with checks on, generated a discriminant mismatch constraint
20391 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20392 Robert Dewar <dewar@adacore.com>
20394 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20395 view is an array type, indicate the component type as well, for
20396 navigation purposes.
20397 (Generate_Reference): Don't consider array ref on LHS to be a case
20398 of violating pragma Unreferenced.
20399 Do not give Ada 2005 warning except on real reference.
20401 2006-02-13 Vincent Celier <celier@adacore.com>
20403 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20404 main source, add switch -mdebug-main=_ada_ so that the executable can
20405 be debugged by the standard VMS debugger.
20406 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20407 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20408 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20409 of the last source, as the binding and linking phases are never
20411 Set all executable obsolete when rebuilding a library.
20413 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20416 2006-02-13 Javier Miranda <miranda@adacore.com>
20419 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20420 code to improve the error message reported when the program has
20421 declarations of abstract interface types and it is not compiled with
20422 the -gnat05 switch.
20423 (P_Access_Definition): Reorganize the code to improve the error
20424 message reported when the new Ada 2005 syntax for anonymous
20425 access types is used and the program is not compiled with the
20428 2006-02-13 Robert Dewar <dewar@adacore.com>
20430 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,

20439 2006-02-13 Vincent Celier <celier@adacore.com>
20441 * prj.adb (Reset): Initialize the first element of table Namings with
20442 the standard naming data.
20444 2006-02-13 Vincent Celier <celier@adacore.com>
20446 * prj.ads (Error_Warning): New enumeration type
20448 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20449 unknown, use the location of the project to report the error.
20450 (When_No_Sources): New global variable
20451 (Report_No_Ada_Sources): New procedure
20452 (Check): New parameter When_No_Sources. Set value of global variable
20454 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20455 (Get_Sources_From_File): Ditto
20456 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20459 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20460 Call Prj.Proc.Process with parameter When_No_Sources.
20462 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20463 Call Recursive_Check with parameter When_No_Sources.
20464 (Recursive_Check): New parameter When_No_Sources. Call itself and
20465 Prj.Nmsc.Check with parameter When_No_Sources.
20466 (Process): New parameter When_No_Sources. Call Check with parameter
20468 (Copy_Package_Declarations): New procedure to copy renamed parameters
20469 and setting the location of the declared attributes to the location
20470 of the renamed package.

20476 * prj-makr.adb (Make): Preserve the comments from the original project
20478 When removing nodes (attributes Source_Dirs, Source_Files,
20479 Source_List_File and package Naming), save the comments and attach the
20480 saved comments to the newly created nodes.
20481 Do not add a with clause for the naming package if one already exists.

20489 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20490 aliased entities to look for the overriden abstract interface
20492 (Is_Interface_Subprogram): Complete documentation.
20493 (Check_Dispatching_Operation): Do not generate code to register the
20494 operation in the dispatch table if the source is compiled with
20495 restriction No_Dispatching_Calls.
20496 (Override_Dispatching_Operation): Check for illegal attempt to override
20497 No_Return procedure with procedure that is not No_Return
20498 (Check_Dispatching_Call): Suppress the check for an abstract operation
20499 when the original node of an actual is a tag-indeterminate attribute
20500 call, since the attribute, which must be 'Input, can never be abstract.
20501 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20502 call to the Input attribute (even when rewritten).
20503 (Propagate_Tag): Augment comment to indicate the possibility of a call
20504 to an Input attribute.
20506 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20507 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20509 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20510 No_Wide_Characters is no longer partition-wide
20511 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)

20516 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20518 2006-02-13 Javier Miranda <miranda@adacore.com>
20520 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20521 handles default-initialized components to keep separate the management
20522 of this feature but also avoid the unrequired resolution and
20523 expansion of components that do not have partially initialized
20525 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20526 (Check_Bounds): Likewise.
20527 (Check_Length): Likewise.
20529 2006-02-13 Javier Miranda <miranda@adacore.com>
20530 Ed Schonberg <schonberg@adacore.com>
20532 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20533 abstract interface type call analyze_and_resolve to expand the type
20534 conversion into the corresponding displacement of the
20535 reference to the base of the object.
20536 (Eval_Attribute, case Width): For systems where IEEE extended precision
20537 is supported, the maximum exponent occupies 4 decimal digits.
20538 (Accessibility_Message): Add '\' in 2-line warning message.
20539 (Resolve_Attribute): Likewise.
20540 (case Attribute_Access): Significantly revise checks
20541 for illegal access-to-subprogram Access attributes to properly enforce
20542 the rules of 3.10.2(32/2).
20543 Diagnose use of current instance with an illegal attribute.
20545 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20547 (Enclosing_Generic_Unit): New function to return a node's innermost
20548 enclosing generic declaration node.
20549 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20550 (Type_Access_Level): The accessibility level of anonymous acccess types
20551 associated with discriminants is that of the current instance of the
20552 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20553 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20554 (Kill_Current_Values_For_Entity): New function
20555 (Enter_Name): Change formal type to Entity_Id
20557 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20558 Ed Schonberg <schonberg@adacore.com>
20559 Gary Dismukes <dismukes@adacore.com>
20561 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20562 Analyze_Compilation_Unit.
20563 Detect and warn on redundant with clauses detected in a package spec
20564 and/or body when -gnatwr is used.

20568 with_clause so that cross-reference information or warning messages on
20569 unused packages can be properly generated
20570 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20571 has Error_Posted set. Prevent infinite loops in illegal programs.
20572 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20573 to the point of the error test requiring the current unit to be private.
20574 This ensures that private with clauses are not exempted from the basic
20575 checking for being a descendant of the same library unit parent as a
20576 withed private descendant unit.
20577 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20578 handle private with clauses properly, as well as to account for cases
20579 where the withed unit is a public descendant of a private ancestor
20580 (in which case the current unit must be a descendant of the private
20581 ancestor's parent). The spec comments were updated accordingly. Also,
20582 the old error message in this subprogram was replaced with error
20583 messages that mirror the errors tested and reported by
20584 Check_Private_Child_Unit.
20585 Parameter and variable names improved for readability.
20586 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20587 private as the precondition for calling
20588 Check_Private_Limited_Withed_Unit since that subprogram has been
20589 revised to test public units as well as private units.

20596 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20597 that Scope_Stack.First = 1.
20598 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20599 were not always properly handled previously.
20600 (Formal_Entity): Complete rewrite, to handle properly some complex case
20601 with multiple levels of parametrization by formal packages.
20602 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20603 to the corresponding derived type declaration for proper semantics.
20605 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20606 (Check_Component): Enforce restriction on components of
20607 unchecked_unions: a component in a variant cannot contain tasks or
20609 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20611 Add pragma Ada_2005 (synonym for Ada_05)
20612 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20613 were not always properly handled previously.
20614 Document that pragma Propagate_Exceptions has no effect
20615 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20616 (Set_Convention_From_Pragma): Check that if a convention is
20617 specified for a dispatching operation, then it must be
20618 consistent with the existing convention for the operation.
20619 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20620 longer required to specify an vtable-ptr component in the record. For
20621 compatibility reasons we leave the support for the previous definition.
20622 (Analyze_Pragma, case No_Return): Allow multiple arguments
20624 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20625 non-overrideen inherited operation with a controlling result as
20626 illegal only its implicit declaration comes from the derived type
20627 declaration of its result's type.
20628 (Check_Possible_Deferred_Completion): Relocate the object definition
20629 node of the subtype indication of a deferred constant completion rather
20630 than directly analyzing it. The analysis of the generated subtype will
20631 correctly decorate the GNAT tree.
20632 (Record_Type_Declaration): Check whether this is a declaration for a
20633 limited derived record before analyzing components.
20634 (Analyze_Component_Declaration): Diagnose record types not explicitly
20635 declared limited when a component has a limited type.
20636 (Build_Derived_Record_Type): Code reorganization to check if some of
20637 the inherited subprograms of a tagged type cover interface primitives.
20638 This check was missing in case of a full-type associated with a private
20640 (Constant_Redeclaration): Check that the subtypes of the partial and the
20641 full view of a constrained deferred constant statically match.
20642 (Mentions_T): A reference to the current type in an anonymous access
20643 component declaration must be an entity name.
20644 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20645 class_wide type to refer to full type, not to the incomplete one.
20646 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20647 available. Required to give support to the certified run-time.
20648 (Analyze_Component_Declaration): In case of anonymous access components
20649 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20650 (Process_Discriminants): For an access discriminant, use the
20651 discriminant specification as the associated_node_for_itype, to
20652 simplify accessibility checks.
20654 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20655 Javier Miranda <miranda@adacore.com>
20657 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20658 abstract interpretations on an operator, remove interpretations that
20659 yield Address or a type derived from it, if one of the operands is an
20661 (Try_Object_Operation.Try_Primitive_Operation,
20662 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20663 location when creating the new reference to a primitive or class-wide
20664 operation as a part of rewriting a subprogram call.
20665 (Try_Primitive_Operations): If context requires a function, collect all
20666 interpretations after the first match, because there may be primitive
20667 operations of the same type with the same profile and different return
20668 types. From code reading.
20669 (Try_Primitive_Operation): Use the node kind to choose the proper
20670 operation when a function and a procedure have the same parameter
20672 (Complete_Object_Operation): If formal is an access parameter and prefix
20673 is an object, rewrite as an Access reference, to match signature of
20674 primitive operation.
20675 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20676 by an expanded name with prefix Standard, when the operands are of an
20677 anonymous access type.
20678 (Remove_Abstract_Operations): If the operation is abstract because it is
20679 inherited by a user-defined type derived from Address, remove it as
20680 well from the set of candidate interpretations of an overloaded node.
20681 (Analyze_Membership_Op): Membership test not applicable to cpp-class

20686 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20687 redundant use clauses.
20688 In particular, if the scope of two use clauses overlaps, but one is not
20689 entirely included in the other, we should not warn. This can happen
20690 with nested packages.
20691 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20692 reported errors. The bug was reported when the compiler was built
20693 with assertions enabled.
20694 (Find_Type): If the node is a 'Class reference and the prefix is a
20695 synchronized type without a corresponding record, return the type
20698 2006-02-13 Javier Miranda <miranda@adacore.com>
20700 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20701 if this is the full-declaration associated with a private declaration
20702 that implement interfaces, then the private type declaration must be
20704 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20705 as aliased. The use of the 'access attribute is not available for such
20706 object (for this purpose the object should be explicitly marked as
20707 aliased, but being an anonymous type this is not possible).
20709 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20710 Robert Dewar <dewar@adacore.com>
20712 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20713 compilation unit is an elaboration scope.
20714 (Add_Task_Proc): Add '\' in 2-line warning message.
20715 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20717 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20718 Javier Miranda <miranda@adacore.com>
20720 * sem_type.adb (Write_Overloads): Improve display of candidate
20722 (Add_One_Interp): Do not add to the list of interpretations aliased
20723 entities corresponding with an abstract interface type that is an
20724 immediate ancestor of a tagged type; otherwise we have a dummy
20725 conflict between this entity and the aliased entity.
20726 (Disambiguate): The predefined equality on universal_access is not
20727 usable if there is a user-defined equality with the proper signature,
20728 declared in the same declarative part as the designated type.
20729 (Find_Unique_Type): The universal_access equality operator defined under
20730 AI-230 does not cover pool specific access types.
20731 (Covers): If one of the types is a generic actual subtype, check whether
20732 it matches the partial view of the other type.
20734 2006-02-13 Thomas Quinot <quinot@adacore.com>
20736 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20737 line. This is necessary to allow In_Extended_Main_Unit to provide
20738 correct results for itypes while writing out expanded source.
20739 (Close_File): No need to update the source_index_table here since it's
20740 now done for each line.
20742 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20743 Robert Dewar <dewar@adacore.com>
20745 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20746 preserve the source unit where the itype is declared, and prevent a
20748 (Note_Implicit_Run_Time_Call): New procedure
20749 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20752 * sprint.ads: Document use of $ for implicit run time routine call

20756 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20759 2006-02-13 Bob Duff <duff@adacore.com>
20761 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20762 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20763 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20764 raise Constraint_Error.
20766 * s-vallli.adb (Scan_Long_Long_Integer): Call
20767 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20768 do not scan leading blanks and sign twice.
20769 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20770 raise Constraint_Error.
20772 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20773 Scan_Long_Long_Unsigned): Split out most of the processing from
20774 Scan_Long_Long_Unsigned out into
20775 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20776 This prevents scanning leading blanks and sign twice.
20777 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20780 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20781 out most of the processing from Scan_Unsigned out into
20782 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20783 This prevents scanning leading blanks and sign twice.
20785 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20786 use with Modular'Value attribute.
20787 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20790 2006-02-13 Robert Dewar <dewar@adacore.com>
20792 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20794 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

20797 (PPC VxWorks): Likewise.
20798 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20799 (forced_callee): Make non-inlinable and non-pure.
20800 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

20803 Ben Brosgol <brosgol@adacore.com>
20804 Robert Dewar <dewar@adacore.com>
20806 * gnat_rm.texi, gnat_ugn.texi: Remove limitations with sparc m64

20915 ({declaraction},Delete_Binder_Generated_Files,{initialization}): Change
20916 Ada bind file prefix on VMS from b$ to b__.
20918 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in

20982 Quentin Ochem <ochem@adacore.com>
20983 Florian Villoing <villoing@adacore.com>
20985 * a-taster.ads, a-taster.adb: New files.
20987 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
20988 link to the version that does nothing. This way the task termination
20989 routine is not executed twice for the environment task when finishing
20990 because of an unhandled exception.
20992 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
20993 handler because of an unhandled exception.
20995 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
20996 System.Tasking.Utilities instead of that in System.Tasking.Stages.
20998 * s-finimp.adb (initialization code): Modify the soft link for the
20999 finalization of the global list instead of Adafinal.
21001 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21002 non-tasking version of the soft link for task termination. We do
21003 nothing since if we are using the non-tasking version it
21004 means that the task termination functionality is not used.
21005 (Null_Finalize_Global_List): Add this null version for the procedure
21006 in charge of finalizing the global list for controlled objects.
21007 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21008 instead for handling run-time termination in a more flexible way.
21009 (Adafinal_NT): This new procedure will take care of finalizing the
21010 global list for controlled objects if needed, but no tasking
21013 * s-tarest.adb (Task_Lock): Do not try to lock again the
21014 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21015 some run-time operations.
21016 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21017 until all nested locks have been released.
21018 (Task_Wrapper): Call the fall-back task termination handler. It
21019 applies to all tasks but the environment task.
21020 (Finalize_Global_Tasks): Add the call for the task termination
21021 procedure for the environment task.
21022 (Task_Wrapper): suppress warnings around declaration of
21023 Secondary_Stack_Address.
21025 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21026 moved to the Common_ATCB record.
21027 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21028 Common_ATCB record.
21029 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21030 Common_ATCB record.
21032 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21033 Fall_Back_Handler, and Specific_Handler.
21035 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21036 defined in Ada.Task_Termination, to avoid circular dependencies.
21037 (Termination_Handler): Redefine this type here, alredy defined in
21038 Ada.Task_Termination, for avoiding circular dependencies.
21039 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21040 for storing task termination handlers. In addition,
21041 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21042 Common_ATCB because it is used by both the regular and the restricted
21044 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21045 Common_ATCB because it is used by both the regular and the restricted
21047 (Common_ATCB): Added a dynamic task analyzer field.
21049 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21050 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21051 (Task_Wrapper): Call the task termination handler. It applies to all
21052 tasks but the environment task.
21053 (Finalize_Global_Tasks): Call the task termination procedure for the
21054 environment task. The call to Finalize_Global_List is now performed
21055 using the soft links mechanism.
21056 (Task_Wrapper): added dynamic stack analysis.
21058 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21059 potentially blocking operations has been moved from
21060 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21061 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21062 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21063 this run-time check.
21065 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21066 of task termination procedure.
21067 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21068 link for the task termination procedure.
21070 * bindusg.adb: (Bindusg): Added documentation for -u option.

21080 * opt.ads: Added flags used by dynamic stack measurement.
21081 (Max_Line_Length): Remove (not used anymore)
21083 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21084 (Standart_Output): new subprogram
21085 (Set_Output): new subprogram
21086 (Put): now uses the value of Current_Out to know if the output has to be
21087 send to stderr or stdout.
21089 * s-stausa.ads: Complete implementation.
21091 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21093 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21094 list of Ada 05 files.
21095 (GNAT Library Units): Add AltiVec files.
21097 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
21098 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21099 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
21101 2005-12-09 Nicolas Setton <setton@adacore.com>
21103 * adaint.c (__gnat_locate_regular_file): Return immediately if
21104 file_name is empty.
21106 2005-12-09 Javier Miranda <miranda@adacore.com>
21107 Hristian Kirtchev <kirtchev@adacore.com>
21109 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21110 to the specification because the frontend generates code that uses this
21112 (Set_Interface_Table): Add missing assertion.
21113 Update documentation describing the run-time structure.
21114 (Displace): New subprogram that displaces the pointer to the object
21115 to reference one of its secondary dispatch tables.
21116 (IW_Membership): Modified to use the new table of interfaces.
21117 (Inherit_TSD): Modified to use the new table of interfaces.
21118 (Register_Interface_Tag): Use the additional formal to fill the
21119 contents of the new table of interfaces.
21120 (Set_Interface_Table): New subprogram that stores in the TSD the
21121 pointer to the table of interfaces.
21122 (Set_Offset_To_Top): Use the additional formal to save copy of
21123 the offset value in the table of interfaces.
21124 Update structure of GNAT Primary and Secondary dispatch table diagram.
21125 Add comment section on GNAT dispatch table prologue.
21126 (Offset_To_Signature): Update the constant value of the Signature field.
21127 (Dispatch_Table): Update comment on hidden fields in the prologue.
21128 (Get_Entry_Index, Get_Prim_Op_Kind, Get_Offset_Index, OSD,
21129 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
21130 the type of formal parameter T to Tag, introduce additional assertions.
21131 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
21133 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
21135 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21136 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21137 record component containing the tag of the secondary dispatch table we
21138 have to use the Offset_To_Top run-time function to get this information;
21139 otherwise if the pointer to the base of the object has been displace
21140 we get a wrong value if we use the 'position attribute.
21142 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21143 all the calls to Expand_Interface_Thunk.
21144 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21145 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21146 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21147 ensure that the interfaces implemented by the ancestors are placed
21148 at the header of the generated list.
21149 (Expand_Interface_Conversion): Handle the case in which the displacement
21150 associated with the interface conversion is not statically known. In
21151 this case we generate a call to the new run-time subprogram Displace.
21152 (Make_DT): Generate and fill the new table of interfaces.
21153 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21154 Get_Tagged_Kind and Set_Tagged_Kind.
21155 (Tagged_Kind): New function that determines the tagged kind of a type
21156 with respect to limitedness and concurrency and returns a reference to
21158 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21159 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21160 primary dispatch table for a type.
21161 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
21162 secondary dispatch table respectively of a tagged type.
21164 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21165 (Expand_Interface_Conversion): New subprogram to indicate if the

21384 legal within a protected type that implements an interface.
21385 (Collect_Interfaces): Do not add to the list the interfaces that
21386 are implemented by the ancestors.
21387 (Derived_Type_Declaration): If the parent of the full-view is an
21388 interface perform a transformation of the tree to ensure that it has
21389 the same parent than the partial-view. This simplifies the job of the
21390 expander in order to generate the correct object layout, and it is
21391 needed because the list of interfaces of the full-view can be given in
21393 (Process_Full_View): The parent of the full-view does not need to be
21394 a descendant of the parent of the partial view if both parents are

21411 (Process_Full_View): Improve the check for the "no hidden interface"
21412 rule as defined by AI-396.
21414 2005-12-09 Robert Dewar <dewar@adacore.com>

21471 available user-specified stream attributes on limited parameters to
21472 also test the type directly rather than only its underlying type (for
21473 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21474 attributes are visible at the point of the subprogram declaration.
21475 For Ada 2005, the error message is modified to indicate that the
21476 type's stream attributes must be visible (again, only for -gnat05).

21508 types use the corresponding record type. This was not needed before
21509 the implementation of Ada 2005 synchronized types because
21510 concurrent types were never tagged types in Ada 95.

21750 checks does not count in the first case, but does in the second).

21756 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21757 elementary types using the operator in standard. It is cleaner not to
21758 modify the programmers intent, especially in the case of floating-point.

21760 it did not matter because we always rewrote a/=b to not(a=b).

21785 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21786 longer sets Elaboration_Checks.

21802 * exp_vfpt.adb: Handle /= case
21803 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

21811 Increase default priority on Lynx from 15 to 17, and meet the Ada
21812 requirement that Default_Priority be ((Priority'First +
21813 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

21915 we are not defining the type.
21916 <E_Record_Type>: Likewise.
21917 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21918 to get advantage of the new maybe_stabilize_reference interface, to
21919 ensure that what we reference is indeed stabilized instead of relying
21920 on assumptions on what the stabilizer does.
21921 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21922 type imported through a limited_with clause, use its non-limited view.
21923 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
21925 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
21926 of #if sections + explicit comparisons of convention identifiers.

21928 before early-returning for certain types when code generation is
21930 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

21932 that we are not defining.
21933 (elaborate_expression_1): Do not create constants when creating
21934 variables needed by the debug info: the dwarf2 writer considers that
21935 CONST_DECLs is used only to represent enumeration constants, and emits
21937 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21938 object with an address clause into an indirect reference, drop the

21951 subtype to build an actual type with bounds template.
21952 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21953 is provided by the front-end, use that subtype to compute the size of
21954 the deallocated object.

21961 maybe_stabilize, for common uses without restriction on lvalues and
21962 without need to check for the success indication.
21963 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21964 pass false instead of 0 as the FORCE argument which is a bool.
21965 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21966 attached to a renaming pointer has been properly stabilized, as no such
21967 object is attached otherwise.
21968 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21969 function uses the "target pointer" return mechanism.
21970 Reinstate conversion of the actual to the type of the formal
21971 parameter before any other specific treatment based on the passing

21977 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

21979 and to let the caller know if the stabilization has succeeded.
21981 * utils2.c (gnat_build_constructor): Only sort the fields for possible
21982 static output of record constructor if all the components are constant.
21983 (gnat_build_constructor): For a record type, sort the list of field
21984 initializers in increasing bit position order.

21986 from a fat or thin pointer type and a constrained object type.
21987 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
21988 types variants, and process special cases of VIEW_CONVERT expressions
21989 as their NOP_EXPR counterpart to ensure we get to the
21990 CORRESPONDING_VARs associated with CONST_DECls.
21991 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
21992 on the right-hand side.

21999 extracting the object if converting to a type variant.
22000 (create_var_decl): When a variable has an initializer requiring code
22001 generation and we are at the top level, check for a potential violation
22002 of a No_Elaboration_Code restriction.
22003 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22004 SIZE and SIZE_UNIT which we need for later back-annotations.

22007 is an unchecked union.

22009 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22010 main variant, just replace the VIEW_CONVERT_EXPR.

22146 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22147 for task component, in the case of a limited aggregate. The enclosed
22148 object declaration will create it earlier. Otherwise, in the case of a
22149 nested aggregate, the object may appear in the wrong scope.
22150 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
22151 (Gen_Assign): If the component being assigned is an array type and the
22152 expression is itself an aggregate, wrap the assignment in a block to
22153 force finalization actions on the temporary created for each row of the
22155 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
22156 structures are initialized after all discriminants are set so that
22157 they can be accessed even when their offset is dynamic.

22166 'Terminated whenever the prefix is of a task interface class-wide type.
22167 (Analyze_Attribute): Add semantic check for attribute 'Identity whenever
22168 the prefix is of a task interface class-wide type.

22185 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22186 and related): For a prefix that is an explicit dereference of an
22187 access to unconstrained packed array type, annotate the dereference
22188 with an actual subtype so GIGI can make a correct size computation.
22189 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22190 'Unrestricted_Access, if the designated type is an interface we
22191 add a type conversion to force the displacement of the pointer
22192 to the secondary dispatch table.
22193 Use Universal_Real instead of Long_Long_Float when we need a high
22194 precision float type for the generated code (prevents gratuitous
22195 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22196 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22197 'Terminated for task interface class-wide objects. Generate a call to
22198 the predefined dispatching routine used to retrieve the _task_id from
22199 a task corresponding record.

22223 (Expand_N_If_Statement): When killing a dead then-branch in an
22224 if-statement that has elsif_parts, recompute the Current_Value node
22225 for any entity whose value is known from the condition of the first
22227 (Expand_N_Return_Statement): When returning a mutable record, convert
22228 the return value into its actual subtype in order to help the backend
22229 to return the actual size instead of the maximum. This is another
22230 aftermath of not returning mutable records on the sec-stack anymore.
22232 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22233 handling of error msg for suspicious reverse range iteration.
22234 (Check_Possible_Current_Value_Condition): Move declaration from body to

22257 2005-11-14 Robert Dewar <dewar@adacore.com>
22259 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
22260 need a high precision float type for the generated code (prevents
22261 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)

22279 attribute of the N_Free_Statement.
22280 Generate itype for classwide designated object in both cases of
22281 user-specified storage pool: specific and class-wide, not only in the
22283 Raise CE when trying to set a not null access type object to null.
22284 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22285 an explicit loop, because freeze nodes make its position variable.

22463 rhs of an assignment even if the type is unconstrained, when the
22464 context is non-expanding.
22465 In an inlined body, if the context type is private,

22522 scope against package Standard. Add comments and a ??? comment.
22523 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22524 on a child instance parent to test that the parent equals

22545 (Build_Derived_Record_Type): Relax the condition that controls the
22546 execution of the check that verifies that the partial view and

22556 (Process_Full_View): Rename local subprogram Find_Interface_In_
22557 Descendant to Find_Ancestor_Interface to leave the code more clear.
22558 Remove wrong code that avoids the generation of an error message
22559 when the immediate ancestor of the partial view is an interface.
22560 In addition some minor reorganization of the code has been done to
22561 leave it more clear.
22562 (Analyze_Type_Declaration): If type has previous incomplete tagged
22563 partial view, inherit properly its primitive operations.
22564 (Collect_Interfaces): Make public, for analysis of formal

22577 be included in the interface list.
22578 (Access_Definition): If the designated type is an interface that may
22579 contain tasks, create Master_Id for it before analyzing the expression
22580 of the declaration, which may be an allocator.

22591 subprogram declaration.
22592 Change name Is_Package to Is_Package_Or_Generic_Package
22593 (Process_Formals): A non null qualifier on a non null named access
22594 type is not an error, and is a warning only if Redundant_Constructs

22598 Ed Schonberg <schonberg@adacore.com>
22600 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
22601 nested within Analyze_Package_Specification to install the private
22602 declarations and use clauses within each of the parent units of a

22605 package associated with a generic instance or formal package, the
22606 private declarations of the parent must be installed (by calling new
22607 procedure Install_Parent_Private_Declarations).
22608 Change name Is_Package to Is_Package_Or_Generic_Package
22609 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22615 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22616 not try to rewrite a renamed stream attribute, because the operations
22617 on the type may not have been generated.
22618 Handle properly a renaming_as_body generated for a stream operation
22619 whose default is abstract because the object type itself is abstract.
22620 (Find_Type): If the type is incomplete and appears as the prefix of a
22621 'Class reference, it is tagged, and its list of primitive operations
22622 must be initialized properly.
22623 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22624 private declaration of a parent unit, prior to compiling the private
22625 part of a child unit, find on the scope stack the proper parent entity
22626 on which to link the use clause.
22627 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22629 (Analyze_Object_Renaming): An attribute reference is not a legal object
22630 if it is not a function call.

22633 Ed Schonberg <schonberg@adacore.com>
22635 * sem_eval.adb: Implement d.f flag
22636 (Subtype_Statically_Match): A generic actual type has unknown
22637 discriminants when the corresponding actual has a similar partial view.
22638 If the routine is called to validate the signature of an inherited
22639 operation in a child instance, the generic actual matches the full view,

22644 Thomas Quinot <quinot@adacore.com>
22646 * sem_res.adb (Resolve_Call): Provide a better error message whenever
22647 a procedure call is used as a select statement trigger and is not an
22648 entry renaming or a primitive of a limited interface.
22649 (Valid_Conversion): If the operand has a single interpretation do not
22650 remove address operations.
22651 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22652 statement to inhibit warning.
22653 (Resolve_Unary_Op): Do not produce a warning when
22654 processing an expression of the form -(A mod B)
22655 Use Universal_Real instead of Long_Long_Float when we need a high
22656 precision float type for the generated code (prevents gratuitous
22657 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22658 (Resolve_Concatenation_Arg): Improve error message when argument is an
22659 ambiguous call to a function that returns an array.
22660 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22661 there is an implicit operator in the given scope if we are within an
22662 instance: legality check has been performed on the generic.
22663 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
22664 after resolving operand, to avoid false warnings on overloaded calls.
22666 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22667 Javier Miranda <miranda@adacore.com>
22670 * sem_type.adb (Covers): In an inlined body, a composite type matches
22671 a private type whose full view is a composite type.
22672 (Interface_Present_In_Ancestor): Protect the frontend against
22673 previously detected errors to ensure that its compilation
22674 with assertions enabled gives the same output that its
22675 compilation without assertions.
22676 (Interface_Present_In_Ancestor): Add support for private types.
22677 Change name In_Actual to In_Generic_Actual (clean up)
22678 (Disambiguate): New predicate In_Actual, to recognize expressions that
22679 appear in the renaming declaration generated for generic actuals, and
22680 which must be resolved in the outer context.

22691 (Set_Public_Status): Do not set Is_Public on an object whose declaration
22692 occurs within a handled_sequence_of_statemets.
22693 (Is_Controlling_Limited_Procedure): Factor some of the logic, account
22694 for a parameterless procedure.
22695 (Enter_Name): Recognize renaming declarations created for private
22696 component of a protected type within protected operations, so that
22697 the source name of the component can be used in the debugger.
22699 2005-11-14 Ed Schonberg <schonberg@adacore.com>

23349 (Write_Field27_Name): Output the name and entity of the field Wrapped_
23351 (Underlying_Type): If we have an incomplete entity that comes from
23352 the limited view then we return the Underlying_Type of its non-limited
23353 view if it is already available.
23354 (Abstract_Interface_Alias): Flag applies to all subrogram kinds,
23355 including operators.
23356 (Write_Field26_Name): Add entry for Overridden_Operation
23357 (Overridden_Operation): New attribute of functions and procedures.
23359 * exp_disp.ads, exp_disp.adb (Default_Prim_Op_Position): Return a
23360 predefined position in the dispatch table for the primitive operations
23361 used in dispatching selects.
23362 (Init_Predefined_Interface_Primitives): Remove the hardcoded number of
23363 predefined primitive operations and replace it with
23364 Default_Prim_Op_Count.
23365 (Make_Disp_Asynchronous_Select_Spec, Make_Disp_Conditional_Select_Spec,
23366 Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
23367 the names of the generated primitive operations used in dispatching
23369 (Init_Predefined_Interface_Primitives): No need to inherit primitives in
23370 case of abstract interface types. They will be inherit by the objects
23371 implementing the interface.

23373 ancestor interface for the elaboration of abstract interface types.
23374 The dispatch table will be inherited by the object implementing the

23381 the entries associated with predefined primitives of all the secondary
23383 (Build_Anonymous_Access_Type): Removed.
23384 (Expand_Interface_Actuals): With the previous cleanup there is no need
23385 to build an anonymous access type. This allows further cleanup in the
23386 code generated by the expander.
23387 (Expand_Interface_Conversion): If the actual is an access type then
23388 build an internal function to handle the displacement. If the actual
23389 is null this function returns null because no displacement is
23390 required; otherwise performs a type conversion that will be
23391 expanded in the code that returns the value of the displaced actual.
23392 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23393 conversions that have no effect in the generated code because no
23394 displacement is required. Code cleanup; use local variables to
23395 avoid repeated calls to the subprogram directly_designated_type().
23397 * exp_util.ads, exp_util.adb (Is_Predefined_Dispatching_Operation):
23398 Classify the primitive operations used in dispatching selects as
23400 (Implements_Limited_Interface): Determine whether some type either

23402 implements a limited interface.
23403 (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
23404 (Expand_Subtype_From_Expr): Do not build actual subtype if the
23405 expression is limited.
23406 (Find_Interface_Tag): Add code to handle class-wide types and
23407 entities from the limited-view.
23409 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
23410 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
23411 POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,

23435 Move with clauses outside Warnings Off now that dependent units are
23437 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
23438 initialization of this unit.
23439 (Specific): Add new procedures Initialize and Delete so that this
23440 package can be used for VxWorks 5.x and 6.x
23441 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
23442 differences between VxWorks 5.x and 6.x
23443 Minor reformatting.
23444 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by
23446 Use only Preelaborate-compatible constructs.

23464 * adaint.c: The wait.h header is not located in the sys directory on
23465 VxWorks when using RTPs.
23466 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
23468 (__gnat_dup): dup is available on Vxworks when using RTPs.
23469 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
23471 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
23473 * expect.c: The wait.h header is not located in the sys directory on
23474 VxWorks when using RTPs.

23493 set of constants that is consistent with the contents of g-soccon.ads.
23495 * gsocket.h: Code imported from gen-soccon.c:
23496 Move all target-specific file inclusions and macro definitions to
23497 gsocket.h, in order to ensure that any C code in socket.c will see a set
23498 of constants that is consistent with the contents of g-soccon.ads.
23499 This change also makes gen-soccon self-contained (removing dependencies
23500 upon GCC internal headers).
23502 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
23504 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
23506 * socket.c: Minor reformatting.

23636 Javier Miranda <miranda@adacore.com>
23638 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23639 from object notation, the original node is unanalyzed and carries no
23640 semantic information, so that accessiblity checks must be performed on
23641 the type of the actual itself.
23642 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23643 compatibility with Build_Protected_Sub_Specification.
23644 (Check_Overriding_Inherited_Interfaces): Add suport to handle

23651 implements at least one interface.
23653 * lib.ads: Extend information in Load_Stack to include whether a given
23654 load comes from a Limited_With_Clause.
23656 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23657 whether a potential circularity is harmless, because it includes units
23658 loaded through a limited_with clause. Extends previous treatment which
23659 did not handle properly arbitrary combinations of limited and
23660 non-limited clauses.
23662 2005-09-01 Nicolas Setton <setton@adacore.com>
23664 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23665 to be encoded as typ___XBLU_lowerbound__upperbound instead of

23694 2005-09-01 Laurent Pautet <pautet@adacore.com>
23696 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23697 position set is provided, we compute one in order to reduce the maximum
23698 length of the keys. This computation first selects a character
23699 position between 1 and the minimum length of the keys in order to
23700 avoid reducing one of the keys to an empty string.
23701 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23702 does not converge. The initialization procedure now comes with a
23703 maximum number of iterations such that when exceeded, an exception is
23704 raised in Compute. The user can initialize this ratio to another value
23706 Reformating and updated headers.

23710 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23711 that given an entity T creates and returns an Itype that duplicates the
23712 contents of T. The returned Itype has the null-exclusion
23713 attribute set to True, and its Etype attribute references T
23714 to keep the association between the two entities.
23715 Update copyright notice
23717 * sem_aggr.adb (Check_Can_Never_Be_Null,
23718 Aggregate_Constraint_Checks, Resolve_Aggregate,

23738 (P_Access_Type_Definition): Add parsing for an anonymous access result
23739 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23740 instead of Set_Subtype_Mark.
23742 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23743 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23744 (Result_Definition): New function for N_Function_Specifications.
23745 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23746 N_Function_Specification.
23747 (Set_Null_Exclusion_Present): Allow this flag for
23748 N_Function_Specification.
23749 (Set_Result_Definition): New procedure for N_Function_Specifications.
23750 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23751 and N_Function_Specification.
23753 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23754 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23755 Add support for LIMITED NEW for Ada 2005 AI-419
23756 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23757 syntax for anonymous access results.

23760 Add Null_Exclusion_Present to spec of N_Function_Specification.
23761 (Result_Definition): New function for N_Function_Specification and
23762 N_Access_Function_Definition.
23763 (Set_Result_Definition): New procedure for N_Function_Specification and
23764 N_Access_Function_Definition.
23766 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23767 Result_Definition for cases of N_Access_Function_Definition and
23768 N_Function_Specification.
23769 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23771 2005-09-01 Vincent Celier <celier@adacore.com>
23773 * lib-writ.adb: Update Copyright notice
23774 (Write_With_Lines): On platforms where file names are case-insensitive,
23775 record the file names in lower case.
23776 (Write_ALI): For D lines, on platforms where file names are
23777 case-insensitive, record the file names in lower case.
23779 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23780 Emmanuel Briot <briot@adacore.com>
23782 * lib-xref.adb (Output_Overridden_Op): Display information on
23783 overridden operation.
23785 * lib-xref.ads: Add documentation on overridden operations.
23787 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23790 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23791 overriding entity information.
23793 2005-09-01 Vincent Celier <celier@adacore.com>
23795 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23796 including those that are inherited.
23798 2005-09-01 Robert Dewar <dewar@adacore.com>
23800 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23802 * par-prag.adb: Implement new pragma Debug_Policy
23804 * sem_prag.adb Implement new pragma Debug_Policy
23805 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23806 Component_Size attribute specification. Give warning for ignored pragma
23809 * snames.h, snames.ads, snames.adb: Introduce entries in
23810 Preset_Names for Name_Disp_Asynchronous_Select,
23811 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23812 Name_Disp_Timed_Select.
23813 New pragma Debug_Policy
23815 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23817 Switch -gnata also sets Debug_Pragmas_Enabled
23819 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23820 handle an explicit -gnata when compiling predefined files.
23822 2005-09-01 Vincent Celier <celier@adacore.com>
23824 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23825 directories of projects that have no Ada sources.
23827 2005-09-01 Robert Dewar <dewar@adacore.com>
23829 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23830 (makes a difference for wide characters)
23832 * widechar.adb, widechar.ads:
23833 Add Wide_Char_Byte_Count feature to count chars vs bytes
23835 2005-09-01 Thomas Quinot <quinot@adacore.com>
23836 Ed Schonberg <schonberg@adacore.com>
23837 Robert Dewar <dewar@adacore.com>
23839 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23840 'Address attribute reference with an overloaded prefix, use the
23841 location of the prefix (not the location of the attribute reference) as
23842 the error location.
23843 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23844 a function renaming thereof, is a valid prefix for 'Size (where it is
23845 intepreted as a function call).
23846 (Statically_Denotes_Entity): New predicate to determine whether the
23847 prefix of an array attribute can be considered static.
23850 (Eval_Attr): Fix failure to evaluate Component_Size for
23851 unconstrained arrays (resulted in wrong value in packed case, since
23852 back end cannot handle this case)
23854 2005-09-01 Robert Dewar <dewar@adacore.com>
23856 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23857 error msgs for most common cases.
23858 Use new errout insertion char < (conditional warning)
23860 2005-09-01 Javier Miranda <miranda@adacore.com>
23861 Ed Schonberg <schonberg@adacore.com>
23863 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23864 become local to the whole package.
23865 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23866 the package was already analyzed the new algorithm "replaces" the
23867 real entities by the shadow ones. This is required to ensure that
23868 the order of these entities in the homonym chains does not change;
23869 otherwise we can have undefined references at linking time because
23870 in case of conflicts the external name of the entities will have
23871 a suffix that depends on the order of the entities in the chain.
23872 (Remove_Limited_With_Clause): Complementary code that completes the
23873 new algorithm and replaces the shadow entities by the real ones.
23874 (Install_Limited_Withed_Unit): When unchaining entities before the
23875 installation of the shadow entities, only regular entities of the
23876 public part must be taken into account. This is required to
23877 keep this routine in synch with the work done by Remove_Limited_
23879 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23880 even if unit is analyzed, because the analysis of the unit is
23881 idempotent in any case, and the limited view of the unit may have to
23882 be installed for proper visibility.
23883 (Expand_Limited_With_Clause): Even if the unit in the implicit
23884 with_clause has been analyzed already, a limited view of the package
23885 must be built for the current context, if it does not exist yet.
23887 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23888 Javier Miranda <miranda@adacore.com>
23889 Gary Dismukes <dismukes@adacore.com>
23891 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23892 defining entity for the instance body, make a new defining identifier
23893 rather than copying the entity of the spec, to prevent accidental
23894 sharing of the entity list.
23895 (Check_Private_View): When exchanging views of private types, build the
23896 list of exchanged views as a stack, to ensure that on exit the exchanges
23897 are undone in the proper order.
23898 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23899 Restore the compilation environment in case of instantiation_error.
23900 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23901 for an anonymous access result.
23902 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23903 (Formal_Entity): Handle properly the case of a formal package that
23904 denotes a generic package renaming.
23906 2005-09-01 Thomas Quinot <quinot@adacore.com>
23908 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23909 clause if the array aggregate is surrounded by parentheses.
23911 2005-09-01 Cyrille Comar <comar@adacore.com>
23912 Gary Dismukes <dismukes@adacore.com>
23913 Ed Schonberg <schonberg@adacore.com>
23914 Javier Miranda <miranda@adacore.com>
23916 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23918 to check if a type is Constrained in cases related to code generation
23919 (rather than semantic checking) since otherwise we do not generate
23920 similar code for mutable private types depending if their
23921 discriminants are visible or not.
23922 (Check_Abstract_Overriding): Do not complain about failure to override
23923 the primitive operations used in dispatching selects since they will
23924 always be overriden at the freeze point of the type.
23925 (Access_Definition): Separate out handling for resetting the scope
23926 of an anonymous access function result type. Retrieve the scope
23927 of the associated function rather than using Current_Scope, which
23928 does not have a consistent value (depends on whether we're in the
23929 middle of analyzing formal parameters). Add ??? comment about
23930 finding a cleaner way to handle the special cases of scope setting.
23931 (Process_Incomplete_Dependents): A protected operation is never a
23932 dispatching operation (only its wrapper may be).
23933 (Build_Derived_Record_Type): In case of tagged private types that
23934 implement interfaces add derivation of predefined primitive
23936 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23937 by two parameters that are used in case of derivation from abstract
23938 interface types: No_Predefined_Prims is used to avoid the derivation
23939 of predefined primitives from the interface, and Predefined
23940 Prims_Only is used to complete the derivation predefined primitives
23941 in case of private tagged types implementing interfaces.
23942 Fix typo in comments
23943 (Find_Interface_In_Descendant): Protect the frontend against
23944 wrong code with large circularity chains.
23945 (Is_Private_Overriding): Add support for entities overriding interface
23946 subprograms. The test failed because Entities associated with overriden
23947 interface subprograms are always marked as hidden (and used to build
23948 the secondary dispatch table); in this case the overriden entity is
23949 available through the field abstract_interface_alias (cf. override_
23950 dispatching_operation)
23951 (Access_Definition): Set the scope of the type to Current_Scope for the
23952 case of a function with an anonymous access result type.
23953 (Access_Subprogram_Declaration): Handle creation of the type entity for
23954 an access-to-function type with an anonymous access result.
23955 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23956 in handling for N_Access_Function_Definition.
23957 (Analyze_Subtype_Declaration): Modify the text of error message.
23958 (Derived_Type_Declaration): Modify the text of error message.
23959 (Process_Subtype): Modify the text of error message plus cleanup
23960 of one redundant error message.
23961 (Analyze_Component_Declaration): Code cleanup.
23962 (Analyze_Object_Declaration): Code cleanup.
23963 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23964 attribute in case of access types. Code cleanup.
23965 (Array_Type_Declaration): Code cleanup.
23966 (Process_Discriminants): Create the new null-excluding itype
23967 if required. Code cleanup.
23968 (Process_Subtype): Create the new null-excluding itype if
23969 required. Code cleanup.
23970 (Build_Derived_Record_Type): Code cleanup to avoid calling
23971 twice the subprogram derive_subprograms in case of private
23972 types that implement interfaces. In this particular case the
23973 subprogram Complete_Subprograms_Derivation already does the
23974 job associated with the second call.
23976 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23977 conversion to the full view when generating an operation for a
23978 discriminant whose type may currently be private.
23980 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23981 Javier Miranda <miranda@adacore.com>
23983 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23984 V (Obj.F), the rewriting does not involve the indexed component, but
23985 only the selected component itself.
23986 Do not apply the transformation if the analyzed node is an actual of a
23987 call to another subprogram.
23988 (Complete_Object_Operation): Retain the entity of the
23989 dispatching operation in the selector of the rewritten node. The
23990 entity will be used in the expansion of dispatching selects.
23991 (Analyze_One_Call): Improve location of the error message associated
23993 (Analyze_Selected_Component): No need to resolve prefix when it is a
23994 function call, resolution is done when parent node is resolved, as
23996 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23997 when attempting to resolve a call transformed from its object notation.
23998 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23999 of the argument list for each interpretation of the operation.
24000 (Try_Object_Operation): The designated type of an access parameter may
24001 be an incomplete type obtained through a limited_with clause, in which
24002 case the primitive operations of the type are retrieved from its full
24004 (Analyze_Call): If this is an indirect call, and the return type of the
24005 access_to_subprogram is incomplete, use its full view if available.
24007 2005-09-01 Javier Miranda <miranda@adacore.com>
24008 Gary Dismukes <dismukes@adacore.com>
24010 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24011 access types the null-exclusion and access-to-constant attributes must
24013 (Analyze_Return_Statement): When the result type is an anonymous access
24014 type, apply a conversion of the return expression to the access type
24015 to ensure that appropriate accessibility checks are performed.
24016 (Analyze_Return_Type): For the case of an anonymous access result type,
24017 generate the Itype and set Is_Local_Anonymous_Access on the type.
24018 Add ??? placeholder for check to disallow returning a limited object
24019 in Ada 2005 unless it's an aggregate or a result of a function call.
24020 Change calls from Subtype_Mark to Result_Definition.
24021 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24022 Result_Definition in call to Make_Function_Specification.
24023 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24024 Set_Result_Definition.
24025 (Make_Inequality_Operator): Change formal Subtype_Mark to
24026 Result_Definition in call to Make_Function_Specification.
24027 (Process_Formals): Create the new null-excluding itype if required.
24028 (New_Overloaded_Entity): For an entity overriding an interface primitive
24029 check if the entity also covers other abstract subprograms in the same
24030 scope. This is required to handle the general case, that is, overriding
24031 other interface primitives and overriding abstract subprograms inherited
24032 from some abstract ancestor type.
24033 (New_Overloaded_Entity): For an overriding entity that comes from
24034 source, note the operation that it overrides.
24035 (Check_Conformance, Type_Conformant): Addition of one new formal
24036 to skip controlling formals in the analysis. This is used to
24037 handle overloading of abstract interfaces.
24038 (Base_Types_Match): Add missing case for types imported from
24039 limited-with clauses
24040 (New_Overloaded_Entity): Add barrier to protect the use of
24041 the "alias" attribute.
24043 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24045 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24046 verify that the procedure and the entry are mode conformant.
24047 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24048 as a different operator, which is often a cut-and-paste error.
24050 2005-09-01 Javier Miranda <miranda@adacore.com>
24051 Ed Schonberg <schonberg@adacore.com>
24053 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24054 used in controlling parameters exclude null because it is necessary to
24055 read the tag to dispatch, and null has no tag.
24056 (Override_Dispatching_Operation): If the previous operation is inherited
24057 from an interface, it becomes hidden and does not participate in later
24060 2005-09-01 Javier Miranda <miranda@adacore.com>
24061 Ed Schonberg <schonberg@adacore.com>
24062 Gary Dismukes <dismukes@adacore.com>
24064 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24065 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24066 the expander will generate the corresponding run-time check to evaluate
24068 (Resolve_Call): Check for legal type of procedure name or prefix that
24069 appears as a trigger in a triggering alternative.
24070 (Valid_Conversion): If expression is ambiguous and the context involves
24071 an extension of System, remove System.Address interpretations.
24072 (Resolve_Qualified_Expression): Reject the case of a specific-type
24073 qualification applied to a class-wide argument. Enhance comment
24074 to explain checking of Original_Node.
24075 (Resolve_Type_Conversion): The location of the error message was not
24076 general enough to handle the general case and hence it has been removed.
24077 In addition, this patch improves the text of the message.
24078 (Resolve_Type_Conversion): Add missing support for access to interface
24080 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24081 do not expand if the expression is the actual in a call, because proper
24082 expansion will take place when the call itself is expanded.
24083 (Resolve_Allocator): If the context is an unchecked conversion, the
24084 allocator inherits its storage pool, if any, from the target type of
24087 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24088 Javier Miranda <miranda@adacore.com>
24090 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24091 inherited interface operation that has an implementation, use the
24092 implementation to avoid spurious ambiguities.
24093 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24094 use the Corresponding_Record_Typ attribute to look for the interface
24095 because it is set by the expander (and hence it is not always
24096 available). For this reason we traverse the list of interfaces
24097 (available in the parent of the concurrent type).
24098 (Interface_Present_In_Ancestor): Handle entities from the limited view
24100 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24102 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24103 from the list of required components.
24104 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24105 primitive procedure of a limited interface with a controlling first
24107 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24109 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24110 capture if it is generated in the second operand of a short-circuit
24112 Do not capture values for variables with address clauses.
24113 (Is_Object_Reference): Treat a function call as an object reference only
24114 if its type is not Standard_Void_Type.
24116 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24118 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24119 to a variable that is statically known to be constant.

24128 Arnaud Charlet <charlet@adacore.com>
24130 * g-dirope.ads: Minor reformatting
24131 Document that bounds of result of Base_Name match the input index
24133 Add documentation on environment variable syntax for Expand_Path
24135 * gnat_ugn.texi: Update documentation to include mention of -m switches
24136 Document new treatment of wide characters in max line length
24138 Remove -gnatL/-gnatZ switches, no longer used.
24139 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24142 * gnat_rm.texi: Add doc for two argument form of pragma
24143 Float_Representation.
24144 Add documentation for pragma No_Strict_Aliasing
24145 Add note that explicit component clause overrides pragma Pack.
24146 Add documentation of pragma Debug_Policy

24901 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24902 longer protected objects. They have been replaced by lower-level
24903 suspension objects made up by a mutex and a condition variable (or
24904 their equivalent given a particular OS) plus some internal data to
24905 reflect the state of the suspension object.
24906 (Initialize, Finalize): Add this initialization procedure for
24907 Suspension_Object, which is a controlled type.
24908 (Finalize): Add the finalization procedure for Suspension_Object,
24909 which is a controlled type.
24911 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24912 Ada.Synchronous_Task_Control because there is no longer a need for a
24913 VxWorks specific version of this package. Target dependencies
24914 has been moved to System.Task_Primitives.Operations.
24916 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24918 (InitializeCriticalSection, EnterCriticalSection,
24919 LeaveCriticalSection, DeleteCriticalSection): Replace the type
24920 pCriticalSection by an anonymous access type so that we avoid problems
24921 of accessibility to local objects.

24927 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
24928 set the environment task mask here.
24929 (Current_State): Add this function that returns the state of the
24931 (Set_False): Add this procedure that sets the state of the suspension
24933 (Set_True): Add this procedure that sets the state of the suspension
24934 object to True, releasing the task that was suspended, if any.
24935 (Suspend_Until_True): Add this procedure that blocks the calling task
24936 until the state of the object is True. Program_Error is raised if
24937 another task is already waiting on that suspension object.
24938 (Initialize): Add this procedure for initializing the suspension
24939 object. It initializes the mutex and the condition variable which are
24940 used for synchronization and queuing, and it sets the internal state
24942 (Finalize): Add this procedure for finalizing the suspension object,
24943 destroying the mutex and the condition variable.

24949 which provides a low-level abstraction (using operating system
24950 primitives) for Ada.Synchronous_Task_Control.

25148 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
25149 type is a class-wide type, emit a run-time check that the accessibility

25367 access to subprograms must be recursive.
25368 (Is_Unchecked_Conversion): Improve the test that recognizes
25369 instantiations of Unchecked_Conversion, and allows them in bodies that
25370 are to be inlined by the front-end. When the body comes from an
25371 instantiation, a reference to Unchecked_Conversion will be an
25372 Expanded_Name, even though the body has not been analyzed yet.

25393 object or component (that is, when Is_Local_Anonymous_Access is true).
25394 Prevent the special checks for conversions of access discriminants in
25395 the case where the discriminant belongs to a nonlimited type, since

25878 different contents.

25887 SA_SIGINFO sigaction should look like. Call

26427 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26428 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26429 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26430 analyzed if expansion is disabled (which could otherwise cause spurious
26431 error messages if expansion has been disabled due to previous
26432 (unrelated) errors).
26434 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26435 is disabled, the entity denoted by the argument is the access type
26436 itself, not an underlying record type, so there is no need to go back
26437 to the Corresponding_Remote_Type.
26439 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26440 Robert Dewar <dewar@adacore.com>

26447 denotes a type in the class.
26448 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26449 of Name_Generic_Dispatching_Constructor.
26451 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26469 a class-wide stream attribute) and then rewrite the attribute name
26470 as the name of the appropriate compiler-generated stream primitive.

26482 itype whose parent is controlled and not yet frozen, do not create a
26483 freeze node for the itype if expansion is disabled.
26485 2005-03-29 Vincent Celier <celier@adacore.com>
26487 * make.adb (Gnatmake): Don't fail if the main project file is declared
26488 as having no Ada sources. Do not display message "no sources to
26489 compile" in quiet output.

26509 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26510 rather than proceed ahead using a junk attribute name.
26512 2005-03-29 Vincent Celier <celier@adacore.com>
26514 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26516 * prj-part.adb (Parse_Single_Project): Set the location of a project
26517 on its defining identifier, rather than on the reserved word "project".
26519 * prj-proc.adb (Expression): Adapt to the fact that default of external
26520 references may be string expressions, not always literal strings.
26521 (Recursive_Process): Set Display_Name equal to Name
26522 when Location is No_Location, that is when there is no actual file.
26523 Get the Display_Name of the project from the source, when it is not a
26525 (Process): Use the Display_Name in error messages
26527 * prj-strt.adb (External_Reference): Allow default to be string
26528 expressions, not only literal strings.
26530 2005-03-29 Vincent Celier <celier@adacore.com>

26541 equivalent type for a remote access-to-subprogram type, go back to the
26542 original RAS entity when displaying an error message, so the casing is
26543 the original source casing.

26552 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26553 subtype if code is being pre-analyzed, to prevent un-expanded
26554 references to protected formals, among others.
26555 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26556 interpretation that can be a call, include the result of the call as a
26557 possible interpretation of the dereference.
26559 * sem_ch5.adb (Process_Bounds): Determine type of range by
26560 pre-analyzing a copy of the original range, and then analyze the range
26561 with the expected type.
26563 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26564 with an overloaded prefix where not all interpretations yield an
26565 access to subprogram, do not rewrite node as a call.
26566 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26567 the node as a call once the context identifies the interpretation of
26568 the prefix whose call yields the context type.
26569 (Valid_Conversion): For the case of a conversion between
26570 local access-to-subprogram types, check subtype conformance using
26571 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26572 detailed error message.

26576 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26577 indicator, indicate that the formal can never be null.
26578 (Process_Formals): If a formal has a non_null indicator, insert the
26579 resulting subtype immediately before the enclosing subprogram decl,
26580 and not at the beginning of the corresponding declarative part, to
26581 prevent access before elaboration (Ada2005).

26704 explanatory error message (including the name of the missing attribute).
26705 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26706 subprogram determines whether a default implementation exists for a
26707 given stream attribute.
26708 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26709 Determine whether to generate a default implementation for each stream
26710 attribute separately, as this depends on the specific attribute.
26712 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26713 limited extension where a stream attribute is missing for a limited
26714 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27308 (gnat_to_gnu_entity, case E_Component): Always look at
27309 Original_Record_Component if Present and not the entity.

27311 of tagged extension types by not making field for components that are
27313 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27314 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27315 expression to the type of the object when the object is constant.
27316 Reverse defer_debug_incomplete_list before traversing it, so that trees
27317 are processed in the order at which they were added to the list. This
27318 order is important when using the stabs debug format.
27319 If we are deferring the output of debug information, also defer this
27320 output for a function return type.
27321 When adding fields to a record, prevent emitting debug information
27322 for incomplete records, emit the information only when the record is
27324 (components_to_record): New parameter defer_debug.
27325 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27326 (gnat_to_gnu_field_decl): New function.
27327 (substitution_list, annotate_rep): Call it.
27328 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27329 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27330 No longer update discriminants to not be a COMPONENT_REF.
27331 (copy_alias_set): Strip padding from input type; also handle
27332 unconstrained arrays properly.
27334 * gigi.h (write_record_type_debug_info): New function.
27335 Convert to use ANSI-style prototypes. Remove unused
27336 declarations for emit_stack_check, elab_all_gnat and
27337 set_second_error_entity.
27338 (gnat_to_gnu_field_decl): New decl.
27340 * utils.c (write_record_type_debug_info): New function.
27341 (finish_record_type): Delegate generation of debug information to
27342 write_record_type_debug_info.
27343 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27344 (update_pointer_to): Fix pasto.
27345 (convert) <UNION_TYPE>: Accept slight type variations when
27346 converting to an unchecked union type.
27348 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27349 replace the N_Freeze_Entity with a null statement.
27351 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27352 within a constrained subcomponent of an enclosing record, place the
27353 freeze nodes in the scope stack entry for the enclosing record.
27354 (Undelay_Type): New Subprogram.
27355 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27356 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27357 within records; allow them to have freeze nodes if their base types
27360 * exp_util.adb (Remove_Side_Effects): Properly test for
27361 Expansion_Delayed and handle case when it's inside an
27362 N_Qualified_Expression.
27364 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27365 Comes_From_Generic, to recognize accurately that the parent type in a
27366 derived type declaration can be traced back to a formal type, because
27367 it is one or is derived from one, or because its completion is derived
27369 (Constrain_Component_Type): If component comes from source and has no
27370 explicit constraint, no need to constrain in in a subtype of the
27372 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27373 Minor change to propagate Is_Ada_2005 flag
27375 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27376 Expansion_Delayed is False.
27377 (assoc_to_constructor): Ignore fields that have a
27378 Corresponding_Discriminant.
27379 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27380 function returns "by target", dereference the target pointer using the
27381 type of the actual return value.
27382 <all>: Be prepared for a null gnu_result.
27383 (processed_inline_subprograms): Check flag_really_no_inline
27384 instead of flag_no_inline.
27385 (set_second_error_entity): Remove unused function.

27390 2005-03-15 Robert Dewar <dewar@adacore.com>
27391 Ed Schonberg <schonberg@adacore.com>
27392 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27394 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27395 Must_Be_Byte_Aligned for cases where we do not need to use a
27396 System.Pack_nn unit.
27398 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27400 Needed now that we do some processing for IN parameters as well. This
27401 may well fix some unrelated errors.
27402 (Expand_Call): Handle case of unaligned objects (in particular those
27403 that come from packed arrays).
27404 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27405 renamed entity is an inherited operation, re-expand the call using the
27406 original operation, which is the one to call.
27407 Detect attempt to inline parameterless recursive subprogram.
27408 (Represented_As_Scalar): Fix to work properly with private types
27409 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27410 accurate estimate. Yields True in far fewer cases than before,
27411 improving the quality of code that depends on this test.
27413 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27414 over both visible and private declarations to remove them from tree,
27415 and mark subprograms declared in package as eliminated, to prevent
27416 spurious use in subsequent compilation of generic units in the context.
27418 * exp_util.ads: Minor cleanup in variable names
27420 * sem_eval.ads, sem_eval.adb: Minor reformatting
27421 (Compile_Time_Known_Bounds): New function
27423 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27425 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27426 determining whether an unchecked conversion is needed for the argument
27427 of an initialization call.
27429 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27431 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27432 that appears in the instantiation rather than the internal subtype
27433 generated in the wrapper package, to avoid anomalies in gigi when the
27434 target is derived from a private type whose full view is an access type.
27436 2005-03-15 Robert Dewar <dewar@adacore.com>
27438 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27440 Add documentation to replace the use of this flag
27441 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27444 2005-03-15 Thomas Quinot <quinot@adacore.com>
27446 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27447 here from exp_attr so it can be shared between exp_attr and exp_dist.
27448 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27449 all TSS names, not a subset thereof, and the previous name introduced
27450 an unnecessarily confusion that a distinction might exist between
27451 "OK" TSS names and some "not OK" TSS names.
27453 2005-03-15 Doug Rupp <rupp@adacore.com>
27455 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27458 2005-03-15 Pascal Obry <obry@adacore.com>
27459 Eric Botcazou <ebotcazou@adacore.com>
27463 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27464 when IN_RTS. This is to work around a bootstrap path problem.
27466 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27467 table and pass it to __gnat_install_SEH_handler().
27468 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27470 * lang.opt: Fix specification of -fRTS=.
27472 2005-03-15 Doug Rupp <rupp@adacore.com>
27473 Bernard Banner <banner@adacore.com>
27474 Vincent Celier <celier@adacore.com>
27475 Arnaud Charlet <charlet@adacore.com>
27478 This change works fine when gnatlib is built from the gcc directory,
27479 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27480 is not passed to ada/Makefile.in, so more work is needed by a
27481 Makefile/configure expert.
27483 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27484 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27485 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27487 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27488 Run ranlib on libgccprefix.a
27489 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27490 (ADA_INCLUDE_SRCS): Split Ada packages.
27492 2005-03-15 Robert Dewar <dewar@adacore.com>
27494 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27496 * impunit.adb: Add GNAT.UTF_32
27498 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27500 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27501 now uses GNAT.UTF_32).
27503 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27504 capabilities for categorizing characters using Unicode categories
27506 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27508 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27509 instantiation that has been rewritten as a package body, retrieve spec
27510 to generate proper name for implicit_with_clause.
27511 (Install_Parents): Recognize a parent that is an instantiation but has
27512 been rewritten as a package declaration during analysis.
27514 2005-03-15 Javier Miranda <miranda@adacore.com>
27515 Ed Schonberg <schonberg@adacore.com>
27517 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27518 parameter reported some error we immediately return. This improves the
27519 behaviour of the frontend in case of errors.
27520 (Install_Parent, Remove_Parent): Introduce new flag
27521 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27522 ancestor of a generic child unit, when the child is being instantiated.
27523 (Inline_Instance_Body): If we are compiling the private
27524 part or the body of a child unit, restore the proper visibility of the
27525 parents after compiling the instance body.
27527 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27528 Javier Miranda <miranda@adacore.com>
27531 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27532 of a private type, in which case it is underlying_type that denotes
27533 the proper task. Also modified to use the new entity attribute
27534 that is directly available in the task type and task subtype entities
27535 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27536 arrays when other dimensions than the first are constrained by
27537 discriminants of an enclosing record.
27538 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27539 a combination of indexed and selected components, find ultimate entity
27540 and generate the appropriate reference for it, to suppress spurious
27542 (Note_Possible_Modification): If an entity name has no entity, return.
27543 (Is_Variable): A function call never denotes a variable.
27544 (Requires_Transient_Scope): For record types, recurse only on
27545 components, not on internal subtypes that may have been generated for
27546 constrained components.
27548 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27550 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27551 Eliminated as candidates for resolution. Both efficient, and avoids
27552 anomalies with operators declared in deleted code.
27553 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27554 expansion is disabled (as when compiling a generic) to prevent spurious
27555 warnings on prefixes of selected components.
27557 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27559 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27560 attached to a list before checking whether it appears in the private
27561 declarations of the current package.
27562 (Make_Inequality_Operator): Insert declaration in proper declarative
27563 list rather than just setting the Parent field, so that
27564 Is_Private_Declaration can handle it properly.
27566 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27568 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27569 a renaming a body, check that the renamed subprogram in not intrinsic.
27570 (Find_Direct_Name): If several use_visible entities hide
27571 each other, and the context is a predefined file compiled through
27572 rtsfind, keep only the entity that comes from a predefined file.
27574 2005-03-15 Geert Bosch <bosch@adacore.com>
27576 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27577 long float padding to also cover AMD64 and IA64.
27579 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27581 * s-imgwch.adb: Add with and use of Interfaces.
27582 (Img_Wide_Character): Change type of Val to Unsigned_16.
27583 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27585 2005-03-15 Matthew Gingell <gingell@adacore.com>

27621 procedures in the bug boxes for various GNAT builds.
27623 2005-03-15 Vincent Celier <celier@adacore.com>
27625 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27630 Cyrille Comar <comar@adacore.com>
27631 Sergey Rybin <rybin@adacore.com>
27633 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27634 too specific and long-winded to be appropriate for the GNAT User's
27636 Warn about use of GCC switches not documented in the GNAT User's Guide,
27637 as these may cause generated code to not conform to Ada semantics.
27638 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27639 Add documentation for -gnat95 and -gnat05 switches
27640 Remove paragraph documenting obsolete way to refer to third party

27765 * exp_ch3.ads, exp_ch3.adb: Fix various places where Wide_Wide_String
27766 was not taken into account.
27767 This includes proper initialization with Normalize_Scalars.
27768 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
27769 normalize scalars cases (particularly the latter) to do a better job
27770 of finding invalid representations.
27772 * s-scaval.ads, s-scaval.adb: Add values for zero invalid values
27774 * s-strops.ads, s-strops.adb: Remove string normalize routines, never
27777 * exp_dist.adb: Add support for wide wide character type

28088 procedure", covering the case of a call to a formal abstract procedure
28089 that has statically tagged operands.
28090 (Check_Dispatching_Call): Check for the case of an actual given by
28091 a tag-indeterminate function call whose type is an ancestor of the

28287 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28288 with expansion disabled. The actual subtype is needed among other
28289 places when the selected component appears in the context of a loop
28290 bound, and denotes a packed array.
28291 (Operator_Check): Always use the first subtype in the
28292 error message, to avoid the appearance of internal base types.
28293 (Transform_Object_Operation): Copy each actual in full
28294 to the parameter associations of the constructed call, rather than
28295 using the shallow copy mechanism of New_Copy_List. This ensures that
28296 the chaining of named associations is done properly.
28297 (Complete_Object_Operation): Rewrite node, rather than
28298 replacing it, so that we can trace back to the original selected
28301 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28302 and calls that use object notation, if the called function is not
28303 declared in a withed unit, place the elaboration constraint on the
28304 unit in the context that makes the function accessible.
28305 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28306 imposes an elaboration constraint between two packages.
28308 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28310 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28311 views of a private type after handling its private dependents, to
28312 maintain proper stack discipline between entry and exit from the
28315 2005-02-09 Cyrille Comar <comar@adacore.com>
28317 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

28333 Slight fix to documentation of -gnaty with no parameters
28335 * xr_tabls.ads: Add ??? comment for missing overall comment
28337 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28338 we now use by default.
28340 * xsnames.adb: Adjust end of file test to look for five space followed
28341 by '#' instead of six spaces. The format of xsnames.adb was modified
28342 in the last update.
28344 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28347 * clean.adb: Minor reformatting.
28349 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28350 gnatname.adb: Minor reformatting
28351 Add 2005 to copyright output when utility is run
28353 * csets.adb: Eliminate obsolete comment
28355 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28358 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28360 2005-02-09 Sergey Rybin <rybin@adacore.com>
28362 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28363 the difference between compact and incompact layout and add the record
28364 representation clause to the example illustrating different layouts.
28365 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28366 component clauses").
28368 2005-02-09 Florian Villoing <villoing@adacore.com>
28370 * gnat_ugn.texi: Fix typos.
28371 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28373 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28374 in the generated documentation.
28376 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28378 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
28380 Update linker wrapper when linking with non GNU C++.
28382 2005-02-09 Pascal Obry <obry@adacore.com>
28385 Document the procedure to debug the DllMain routine on Windows.

28418 * exp_util.ads: Minor correction in comment.
28420 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28422 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28423 since this procedure is now too complex to be worth inlining.
28425 2005-02-09 Richard Henderson <rth@redhat.com>
28427 * utils.c (gnat_define_builtin): Remove.
28428 (gnat_install_builtins): Use build_common_builtin_nodes.

28618 No_Dependence restrictions.
28619 (Install_Withed_Unit): Add code to implement AI-377 and diagnose

28670 2005-01-03 Olivier Hainque <hainque@adacore.com>
28672 * decl.c (compatible_signatures_p): New function. The intended purpose
28673 is to check if two function signatures for a call-site and a callee are
28674 compatible enough for the call to be valid. The underlying purpose is
28675 to check if a call to a mapped builtin is using the right interface.
28676 The current code actually does not check antyhing - this a placeholder
28677 for future refinements.

28726 variants of the PCS.
28727 Reorganise RPC receiver generation to reduce differences between the
28728 structure of GARLIC and PolyORB RPC receivers.
28729 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
28731 Simplify elaboration code for RCI packages.
28733 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
28734 generation to reduce differences between the structure of GARLIC and

29097 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29098 dereference is rewritten to an explicit one, generate a reference to

29216 used to record an implicit dereference as a read operation on its
29217 prefix when operating under -gnatc. Necessary to avoid spurious
29218 'variable assigned but never read' warnings in that mode.
29219 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29220 is a non-overloaded implicit dereference, call the above subprogram to
29221 ensure proper recording of references.
29223 2004-12-07 Gary Dismukes <dismukes@adacore.com>

29263 2004-12-07 Vincent Celier <celier@adacore.com>
29264 Sergey Rybin <rybin@adacore.com>
29266 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
29267 Files" with the new tool and package names.
29268 Reformatting to suppress most of the warnings for line too long
29269 Document the new section "Project Search Path:" in the output of
29271 Add gnatmetric section
29273 2004-12-07 Vincent Celier <celier@adacore.com>
29275 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29276 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29277 and -eit to -ept. Added qualifier
29278 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29280 2004-11-27 Andreas Schwab <schwab@suse.de>
29282 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29284 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29286 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29287 internal implementation unit GNAT.Sockets.Thin,
29288 as their usage for sockets is non-portable (using the read and write
29289 functions from the system runtime library is fine on UNIX but won't
29290 work under Windows).
29292 * mingw32.h: Update copyright notice.
29294 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29296 * ada-tree.h: Minor reformatting of previous change to avoid lines
29297 longer than 79 characters.
29299 2004-11-25 Olivier Hainque <hainque@adacore.com>
29301 * tb-gcc.c: GCC infrastructure based implementation of

29315 2004-11-21 Andreas Jaeger <aj@suse.de>
29317 * stylesw.adb: Change Style_Check_Subprogram_Order to
29318 Style_Check_Order_Subprograms.
29320 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29322 * adaint.h, adaint.c
29323 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29325 Add also a cast to kill another warning.
29326 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29327 parameter with the priority class of the parent process instead of
29328 always using the NORMAL_PRIORITY_CLASS.
29329 (__gnat_dup): New function.
29330 (__gnat_dup2): New function.
29331 (__gnat_is_symbolic_link): Enable the effective body of this
29332 function when __APPLE__ is defined.
29334 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29337 2004-11-18 Olivier Hainque <hainque@adacore.com>
29339 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29340 address of which may be used to represent "others" and "all others"
29341 choices in exception tables, instead of the current harcoded
29342 (void *)0 and (void *)1.
29343 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29345 * gigi.h (others_decl, all_others_decl): New decls representing the
29346 new Others_Value and All_Others_Value objects.
29347 (struct attrib): Rename "arg" component as "args", since GCC expects a
29348 list of arguments in there.
29350 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29351 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29354 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29355 others_decl and all_others_decl instead of hardcoded dummy addresses
29356 to represent "others" and "all others" choices, which is cleaner and
29357 more flexible with respect to the possible eh pointer encoding policies.
29359 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29360 (process_attributes): Account for the naming change of the "args"
29361 attribute list entry component.
29363 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29364 cumulating attributes for different entities into a single list.
29365 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29366 attributes for the current entity and propagate first subtype
29367 attributes to other subtypes.
29368 <E_Procedure>: Attribute arguments are attr->args and not
29369 attr->arg any more.
29370 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29371 argument provided, as this is what GCC expects. Use NULL_TREE instead
29374 2004-11-18 Robert Dewar <dewar@adacore.com>
29376 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29377 Minor reformatting througout (including new function specs)
29378 Add ??? comments asking for clarification.
29380 2004-11-18 Thomas Quinot <quinot@adacore.com>
29382 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29383 incomplete duplicate implementation of this subprogram from butil.
29385 2004-11-18 Thomas Quinot <quinot@adacore.com>
29387 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29388 procedures factors the common processing for building an RPC receiver
29389 for an RCI package or an RACW type.
29390 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29391 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29392 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29394 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29396 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29398 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29399 distribution subprogram identifiers that are either subprogram numbers
29401 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29402 string distribution identifiers assigned to a given subprogram.
29403 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29404 (Add_RAS_Dereference_TSS): Add comments.
29405 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29406 is not referenced yet because it will be used by the PolyORB DSA
29408 (Insert_Partition_Check): Remove fossile code.
29409 (First_RCI_Subprogram_Id): Document this constant.
29410 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29412 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29413 replaced with calls to Get_Library_Unit_Name_String. Previously there
29414 were several instances of the same code in different locations in the
29415 compiler; this checkin completes the replacement of all of these
29416 instances with calls to a common subprogram.
29417 Minor reformatting.
29419 * sem_dist.adb: Remove comment noting that RPC receiver generation
29420 should be disabled for RACWs that implement RASs.
29421 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29423 * sem_util.ads, sem_util.adb (Has_Stream): New function
29424 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29425 qualified name of a library unit into the name buffer.
29426 (Note_Possible_Modification): Generate a reference only
29427 if the context comes from source.
29429 * snames.ads (PCS_Names): New subtype corresponding to names of
29430 supported implementations of the Partition Communication Subsystem
29431 (PCS) (i.e. the runtime library support modules for the distributed
29434 2004-11-18 Robert Dewar <dewar@adacore.com>
29435 Ed Schonberg <schonberg@adacore.com>
29437 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29438 (Has_Rep_Pragma): New function
29439 (Has_Attribute_Definition_Clause): New function
29440 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29441 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29443 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29445 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29446 (Expand_Pragma_Psect_Object): New procedure
29447 These procedures contain the revised and cleaned up processing for
29448 these two pragmas. This processing was formerly in Sem_Prag, but
29449 is more appropriately moved here. The cleanup involves making sure
29450 that the pragmas are properly attached to the tree, and that no
29451 nodes are improperly shared.
29453 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29454 pragmas to Exp_Prag, which is more appropriate.
29455 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29456 check for duplicates Remove use of Is_Psected flag, no longer needed.
29457 Use new Make_String_Literal function with string.
29459 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29460 that are functions return universal values, that have to be converted
29461 to the context type.
29462 Use new Make_String_Literal function with string.
29463 (Get_Stream_Convert_Pragma): New function, replaces the use of
29464 Get_Rep_Pragma, which had to be kludged to work in this case.
29466 * freeze.adb: Use new Has_Rep_Pragma function
29468 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29469 function with string.
29470 Use new Has_Rep_Pragma function.
29472 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29475 2004-11-18 Robert Dewar <dewar@adacore.com>
29477 * errout.ads, errout.adb: (First_Sloc): New function
29479 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29480 check (-gnatyx) instead of being included as a redundant construct
29483 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29484 Style_Check_Order_Subprograms.
29486 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29487 stylesw.adb: Add Style_Check_Xtra_Parens
29489 * usage.adb: Add line for -gnatyx (check extra parens)
29491 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29493 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29494 Robert Dewar <dewar@adacore.com>
29496 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29497 discriminant of a constrained subtype, analyze the copy of the
29498 corresponding constraint, because in some cases it may be only
29499 partially analyzed.
29500 Removes long-lived ??? comments.
29502 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29503 handled controlled or secondary-stack expressions within the
29504 iteration_scheme of a loop.
29506 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29507 bounds that may contain functions calls, to prevent memory leaks when
29508 the bound contains a call to a function that uses the secondary stack.
29509 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29510 generate temporaries for loop bounds that might contain function calls
29511 that require secondary stack and/or finalization actions.
29513 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29514 selected component and the selector is overloadable (not just a
29515 function) treat as function call, Analyze_Call will disambiguate if
29517 (Analyze_Selected_Component): Do not generate an actual subtype for the
29518 selected component if expansion is disabled. The actual subtype is only
29519 needed for constraint checks.
29520 (Analyze_Allocator): If restriction No_Streams is set, then do
29521 not permit objects to be declared of a stream type, or of a
29522 composite type containing a stream.
29524 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29525 No_Streams no longer prohibits with'ing this package.
29527 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29528 discriminants, but the parent base has unknown discriminants, there is
29529 no discriminant constraint to inherit. Such a discrepancy can arise
29530 when the actual for a formal type with unknown discriminants is a
29531 similar private type whose full view has discriminants.
29532 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29533 do not permit objects to be declared of a stream type, or of a
29534 composite type containing a stream.
29536 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29538 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29539 protected operations.
29541 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29542 generated name, it complicates decoding in gdb and hinders debugging
29543 of protected operations.
29544 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29545 flag for the protected entry barrier function.
29546 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29547 flag for the protected entry function.
29549 2004-11-18 Nicolas Setton <setton@adacore.com>
29551 * expect.c: Define __unix__ when __APPLE__ is defined.
29553 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29554 Darwin-specific section.
29556 * lang-specs.h: Change the placement of the %1 marker.
29557 Works around the fact that gcc adds -fPIC by default under Darwin.
29559 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29561 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29562 type of the object with the packed array type, set the Analyzed flag
29563 on the object if it is an entity or simple indexed component, to avoid
29564 spurious type errors.
29566 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29568 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29569 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29570 separate line from the version message.
29572 2004-11-18 Ed Falis <falis@adacore.com>
29574 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29576 (init_float): Eliminate initialization of floating point status for
29577 AE653. The instructions have no effect for vThreads.
29579 2004-11-18 Vincent Celier <celier@adacore.com>
29581 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29582 gnatbind is invoked with -shared.
29584 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29586 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29587 for Detect_Blocking which is redundant with the check done within the
29588 procedure Protected_Single_Entry_Call.
29589 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29590 Detect_Blocking which is redundant with the check done within the
29591 procedure Protected_Single_Entry_Call.
29593 2004-11-18 Vincent Celier <celier@adacore.com>
29595 * makegpr.adb (Compile): Put the compiling switches (in package
29596 Compiler and on the command line) immediately after "-c", instead of
29597 at the end of the command line invocation of the compiler, when
29598 compiling a non-Ada file.
29599 (Build_Global_Archive): When there is no need to rebuild the archive,
29600 set Global_Archive_Exists, so that the archive is passed to the linker
29603 2004-11-18 Robert Dewar <dewar@adacore.com>
29604 Sergey Rybin <rybin@adacore.com>
29607 Remove extra paren check from list of checks for redundant constructs
29608 Add documentation of new -gnatyx style check (check extra parens)
29609 Remove paragraph about gnatelim debug options.
29611 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29612 objects rather than forbidding dependencies on the package Ada.Streams.
29614 * sinfo.ads: Add ??? note that we should document pragmas passed to
29617 * g-expect.ads: Fix a few typos in the comments.
29619 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29621 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29624 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29626 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29628 2004-11-07 Andreas Schwab <schwab@suse.de>
29630 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29632 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29635 * Makefile.in (darwin): Set soext to .dylib.
29637 2004-10-26 Vincent Celier <celier@gnat.com>
29638 Thomas Quinot <quinot@act-europe.fr>
29640 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29641 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29642 there is no use of GNAT.Sockets.Constants.
29643 Remove remaining pragma Import for C_Write
29644 Remove C_Read and C_Write from internal implementation unit
29645 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29646 the read and write functions from the system runtime library is fine
29647 on UNIX but won't work under Windows).
29649 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29650 (Check_Selector): Use C_Recv instead of C_Read.
29651 Selectors are the GNAT.Sockets abstraction to perform a select()
29652 call on a set of descriptors. To allow abortion of an ongoing
29653 select operation, some data is written to a dedicated socket that
29654 is always monitored.
29655 Under Windows, the write and read library functions cannot operate
29656 on sockets, so we need to use send and recv instead, which is portable
29657 across all supported platforms.
29659 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29660 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29661 (using the read and write functions from the system runtime library is
29662 fine on UNIX but won't work under Windows).
29664 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29666 * mlib-tgt-darwin.adb: New file.
29668 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29669 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29670 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29671 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29674 * Makefile.in: Add support for building shared libraries under Darwin.
29675 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29676 the low level EH init subprogram to be called from __gnat_initialize.
29678 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29679 indicates which options to pass to the archive indexer.
29681 * mlib-utl.adb: Add support for calling ranlib with additional
29682 options. This is needed for instance under Mac OS X.
29683 (Ranlib_Options): New global variable, used to store the potential
29684 options to pass to ranlib.
29685 (Ar): Use Ranlib_Options when spawning ranlib.
29686 (Initialize): Set the value of ranlib option.
29688 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29690 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29691 instead of 8K, to reflect the real potential needs for stack-checking
29694 2004-10-26 Pascal Obry <obry@gnat.com>
29696 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29698 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29699 Windows only the initial thread stack size can be set so it is good to
29700 start we a low stack size.
29701 The OS will adjust the size as needed.
29703 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29704 Nicolas Setton <setton@act-europe.fr>
29706 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29707 "__unix__" instead of "unix".
29708 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29709 sections were just mistakenly ignored. The former is
29710 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29711 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29712 of hpux. This prevents an unwanted definition of the symbol
29713 convert_addresses in adaint.o.
29715 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29717 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29718 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29720 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29722 * a-filico.ads, a-filico.adb: fix incorrect header.
29724 2004-10-26 Javier Miranda <miranda@gnat.com>
29726 * a-ststio.ads: Fix typo in identifier
29728 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29730 * sem_ch4.adb: Minor reformatting.
29732 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29734 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29735 enabled, check the result of unary and binary operations when the
29736 expression is the right-hand side of an assignment.
29738 2004-10-26 Vincent Celier <celier@gnat.com>
29740 * clean.adb (Delete): Do not output warnings when in quiet output and
29741 not in verbose mode.
29742 (Force_Deletions): New Boolean flag, defaulted to False
29743 (Delete): Only delete a file if it is writable, and when
29744 Force_Deletions is True.
29745 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29746 (Usage): Line for new switch -f
29747 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29750 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29752 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29753 JM type only if its size matches that of the wrapper. When a size is
29754 prescribed and the field is not aliased, remove the wrapper of a JM
29755 type only if the size is not greater than that of the packed array.
29756 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29759 2004-10-26 Geert Bosch <bosch@gnat.com>
29761 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29762 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29763 (Pred): Implement in terms of Succ.
29765 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29767 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29768 unchecked conversion is safe for in-place use if the expression of the
29769 conversion is safe.
29770 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29771 be expandable in place even if the aggregate does not come from source.
29772 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29773 designated object of an allocator in place, rather than building it
29774 first on the stack. The previous scheme forces a full copy of the array,
29775 and may be altogether unsusable if the size of the array is too large
29776 for stack allocation.
29778 2004-10-26 Robert Dewar <dewar@gnat.com>
29780 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29781 compares if the component is atomic.
29783 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29784 array assignment if the component type is atomic.
29786 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29787 Eric Botcazou <ebotcazou@act-europe.fr>
29789 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29790 is aliased and is a by_reference type, do not pass by copy.
29791 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29792 detect whether the call is in the right side of an assignment or
29793 the expression of an object declaration. Recurse on component
29794 association within aggregates.
29795 Call it in the condition that determines whether the temporary is
29796 necessary for correct stack-checking.
29798 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29800 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29801 RACW_Type, used in the PolyORB version.
29802 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29803 version and the GARLIC version.
29805 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29806 Rename RCI_Info to RCI_Locator for better consistency between the
29807 GARLIC and PolyORB versions of the distributed systems annex.
29808 (DSA_Implementation_Name): This enumeration lists the possible
29809 implementations of the Partition Communication Subsystem for the
29810 Distributed Systems Annex (DSA). The three available implementations
29811 are the dummy stub implementation (No_DSA), and two versions based on
29812 two different distribution runtime libraries: GARLIC and PolyORB. Both
29813 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29815 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29818 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29819 between the GARLIC and PolyORB versions of the distributed systems
29821 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29823 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29825 * gnat1drv.adb: Suppress calling the back end when
29826 Frontend_Layout_On_Target is true.
29828 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29830 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29831 Set_Read_Only): New subprograms.
29832 These new routines allow the user to set or unset the Owner execute
29833 and Owner write permission flags on a file.
29835 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29836 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29838 2004-10-26 Matthew Gingell <gingell@gnat.com>
29840 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29842 2004-10-26 Pascal Obry <obry@gnat.com>
29844 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29845 memory before the faulting page we properly test the process read
29846 access for this address using appropriate Win32 routine.
29847 (HPUX sections): guard with "__hpux__" instead of "hpux".
29849 2004-10-26 Robert Dewar <dewar@gnat.com>
29851 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29852 entry parameter if pragma Unreferenced set, since we do not properly
29853 handle the case of multiple parameters.
29855 2004-10-26 Vincent Celier <celier@gnat.com>
29857 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29858 (Ada_Objects_Path.Add): For a library project, add to the object path
29859 the library directory only if there is no object directory or if the
29860 library directory contains ALI files.
29861 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29863 2004-10-26 Vincent Celier <celier@gnat.com>
29865 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29866 extension of library projects.
29868 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29869 path defaults to ".:<prefix>/lib/gnat".
29870 (Parse): For an extending all project, allow direct import of a project
29871 that is virtually extended.
29873 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29874 the specified name is directly imported, return its ID. Otherwise, if
29875 an extension of this project is imported, return the ID of the
29878 2004-10-26 Robert Dewar <dewar@gnat.com>
29880 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29881 (Sub3): New procedure, used by Scaled_Divide
29882 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29883 correct more than one instance of failure to propagate carries
29885 (Double_Divide): Handle overflow case of largest negative number
29886 divided by minus one.
29888 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29889 the case of a quotient value out of range.
29892 2004-10-26 Robert Dewar <dewar@gnat.com>
29894 * s-bitops.adb (Bit_Eq): Remove redundant check.
29896 * s-bitops.ads: Minor comment updates
29897 Change some occurrences of Address to System.Address
29899 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29901 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29903 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29904 accessibility check to prefix that is a protected operation.
29906 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29908 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29909 empty, post message on stub.
29911 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29912 Javier Miranda <miranda@gnat.com>
29914 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29915 current instance appears within a unit that is directly in the context
29917 Used to determine whether the body of the instance should be analyzed
29918 immediately after its spec, to make its subprogram bodies available
29919 for front-end inlining.
29920 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29921 constraint is not allowed on the component type (AARM 12.5.3(3))
29923 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29925 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29926 'Storage_Pool): enhance, document & limit detection of non-sharable
29929 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29931 * s-pooglo.ads: Add more documentation now that this pool is properly
29934 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29936 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29937 or protected type with discriminants, do not constrain the
29938 corresponding record type if the subtype declaration has no
29939 discriminant constraints. This can be the case in source code, or in
29940 the subtype declaration created to rename an actual type within an
29943 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29945 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29946 different kind of stub (possibly wrong name for file), do not check
29948 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29949 includes call to some function that returns an unconstrained type, do
29952 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29954 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29955 appear in the code for the main unit. Dependencies among units in the
29956 context of the main unit are established when those other units are
29957 compiled. Otherwise spurious elaboration constraints can generate
29958 incorrect elaboration circularities.
29960 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29961 Ed Schonberg <schonberg@gnat.com>
29963 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29964 subprogram is called with a parameter that is not an object name. This
29965 situation arises for some cases of illegal code, which is diagnosed
29966 later, and in this case it is wrong to call Is_Aliased, as that might
29967 cause a compiler crash.
29968 (Explain_Limited_Type): Refine previous fix to include
29969 inherited components of derived types, to provide complete information.
29971 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29972 is the prival for a protected object.
29973 It is necessary to mark this entity as a variable, in addition to
29974 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29975 modified to avoid checking the Aliased flag on entities that are not
29976 objects. (Checking that flag for non-objects is erroneous and could
29977 lead to a compiler crash).
29979 2004-10-26 Robert Dewar <dewar@gnat.com>
29981 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29982 X_Frac = 0.5, then we know that the number X must be positive.
29983 (Succ): Remove the same redundant test, and also fix the primary test
29984 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29986 (Decompose): Add fuller comments to spec
29988 2004-10-26 Pascal Obry <obry@gnat.com>
29990 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29991 validity (process must have read access). Set to 0 in all other cases.
29992 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29993 violation on Win32.
29994 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29995 segmentation violation.
29997 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29999 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30000 whose type is a constructed subtype of an aliased object with an
30001 unconstrained nominal subtype, convert the actual to the constructed
30002 subtype before taking its address.
30004 2004-10-26 Vincent Celier <celier@gnat.com>
30006 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30007 (Is_Path_Name_Case_Sensitive): New function
30009 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30010 (Base_Name, Simple_Name, Current_Directory, Compose,
30011 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30014 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30015 Vasiliy Fofanov <fofanov@act-europe.fr>
30016 Vincent Celier <celier@gnat.com>
30018 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30019 "memory management issues" section and document some of the useful
30020 memory pools provided as part of the GNAT library.
30021 Remove "virtual" from declaration of A::method2 in
30022 the simple example of Ada/C++ mixed system.
30023 Library Projects may be virtually extended: their virtual extensions
30024 are not Library Projects.
30025 Added section on extending project hierarchies.
30027 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30029 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30031 (__gnat_portable_spawn): Remove const.
30033 * mingw32.h (MAXPATHLEN): Check for previous definition.
30035 2004-10-17 Matthias Klose <doko@debian.org>
30037 * gnatvsn.ads: Set gnat library version to 4.0.
30039 2004-10-05 Vincent Celier <celier@gnat.com>
30041 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30043 2004-10-04 Laurent Guerby <laurent@guerby.net>
30046 * Makefile.in: Define and use RANLIB_FLAGS.
30048 2004-10-04 Pascal Obry <obry@gnat.com>
30050 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30051 other x86 platforms).
30053 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30055 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30056 in general and triggers stack alignment adjustment for thread entry
30057 points on targets where this is necessary.
30059 2004-10-04 Bernard Banner <banner@gnat.com>
30062 * Makefile.in: Add section for powerpc linux
30063 Add variant i-vxwork-x86.ads
30065 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30067 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30069 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30070 table registration calls when need be. Ensures no reference to the crt
30071 ctors symbol are issued in the SJLJ case, which avoids possible
30072 undefined symbol errors in the case of modules to be statically linked
30075 2004-10-04 Javier Miranda <miranda@gnat.com>
30077 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30078 in-line the code corresponding to subprogram Analyze_Actuals. In
30079 addition, analyze the actuals only in case of subprogram call.
30081 2004-10-04 Ed Falis <falis@gnat.com>
30083 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30085 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30087 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30088 in the documentation.
30090 2004-10-04 Robert Dewar <dewar@gnat.com>
30092 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30094 (Analyze_Block_Statement): Add circuitry to detect following dead code
30095 (Check_Unreachable_Code): Handle case of block exit
30097 2004-10-04 Robert Dewar <dewar@gnat.com>
30099 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30100 (XMatchD): Avoid warning for Logic_Error call
30102 2004-10-04 Robert Dewar <dewar@gnat.com>
30104 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30105 consider expressions buried within a procedure actual to be an actual.
30106 This caused some blowups with uses of packed slices within a procedure
30109 2004-10-04 Robert Dewar <dewar@gnat.com>
30111 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30112 longer need to be initialized to zero.
30113 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30114 initialized to zero.
30116 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30117 considered valid, even if the representation is modular. That's correct
30118 now that we no longer initialize packed modular arrays to zero.
30120 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30121 suffixes. These are now documented as the only cases in which the
30122 debugger ignores outer records.
30123 Previously, the spec allowed arbitrary suffixes for this purpose.
30124 Change name of LJM to JM for packed array pad records
30125 Create separate section on packed array handling, and add a whole new
30126 set of comments to this section describing the situation with packed
30127 modular types and justification requirements depending on endianness.
30129 2004-10-04 Robert Dewar <dewar@gnat.com>
30131 * a-except.adb: Add a comment for last change

30140 * sem_util.ads: Minor comment update
30142 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30144 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30145 Inline_Always when in Configurable_Run_Time mode.
30147 * sem_prag.adb (Process_Convention): If entity is an inherited
30148 subprogram, apply convention to parent subprogram if in same scope.
30149 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30150 when in Configurable_Run_Time mode.
30152 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30154 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30155 class_wide type after component list has been inherited.
30157 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30159 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30160 Denotes_Previous_Actual, to handle properly the case of a private
30161 actual that is also the component type of a subsequent array actual.
30162 The visibility status of the first actual is not affected when the
30163 second is installed.
30164 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30165 make fully recursive the treatment of formals of packages declared
30167 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30168 the above on exit from an instantiation.
30169 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30170 current instantiation which is now complete.
30171 (Analyze_Package_Instantiation): No instantiated body is needed if the
30172 main unit is generic. Efficient, and avoid anomalies when a instance
30173 appears in a package accessed through rtsfind.
30175 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30177 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30178 do not generate a declaration for a temporary if the call is part of a
30179 library-level instantiation.
30181 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30183 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30184 searching for a limited component to flag.
30186 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30187 expansion of Input, to account for the fact that the implicit call
30188 generated by the attribute reference must freeze the user-defined
30189 stream subprogram. This is only relevant to 'Input, because it can
30190 appear in an object declaration, prior to the body of the subprogram.
30192 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30193 expansion can proceed and further errors uncovered.
30194 (Minor clean up): Fix cases of using | instead of \ for continuation
30197 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30206 specified alignment before validating size.
30207 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30208 stripped-down declaration for the type of the inner field when making
30211 * utils.c (finish_record_type): Do not compute the size in units
30212 incrementally. Instead compute it once for the rep clause case.
30213 Use gcc_assert and gcc_unreachable.
30215 2004-10-04 Vincent Celier <celier@gnat.com>
30217 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30219 (Is_Valid_Path_Name): Take '/' as a directory separator.
30221 2004-10-04 Vincent Celier <celier@gnat.com>
30223 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30224 (Extended_Project) only if Extended_Project is defined, to avoid
30226 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30228 (Parse_Single_Project): Ditto.
30230 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30231 Add_To_Project_Path for virtual projects.
30233 2004-10-04 Vincent Celier <celier@gnat.com>
30235 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30236 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30237 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30238 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30239 parameter Options_2.
30241 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30242 Build_Dynamic_Library with an empty Options_2.
30244 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30247 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30248 directory separator, if any.
30249 (Gprmake): Do not allow mains on the command line for library projects.
30250 Do not attempt to link when the project is a library project.
30251 (Library_Opts): New table to store Library_Options.
30252 (Build_Library): If Library_Options is specified, pass these options
30253 when building a shared library.
30255 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30257 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30258 the end of this procedure now that the unlock operation was inserted
30261 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>

30264 corresponding to the Preallocated_Stacks flags in System.
30265 (Get_Target_Parameters): Including the processing for
30266 Preallocated_Stacks.

30277 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30278 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30279 used to signal whether the compiler creates the required stacks and
30280 descriptors for the different tasks (when True) or it is done by the
30281 underlying operating system at run time (when False).
30282 It is initially set to False in all targets.
30284 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30285 if it is supported by the target.
30286 (Make_Task_Create_Call): Pass the stack address if it has been
30287 previously created. Otherwise pass a Null_Address.
30289 * snames.adb: Add _stack.
30291 * snames.ads: Add Name_uStack. Required to allow the expander to
30292 statically allocated task stacks.
30294 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30295 Stack_Address argument.
30296 Check that its value is equal to Null_Address because this target does
30297 not support the static stack allocation.
30299 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30301 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30304 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30306 * exp_dist.adb: Split declaration of asynchronous flag out of
30307 Add_RACW_Read_Attribute.
30308 Minor reformatting for better alignment with PolyORB version.
30309 Store the entity for the asynchronous flag of an RACW, rather than the
30310 expression, in the asynchronous flags table. This will allow this flag
30311 to be used in other subprograms beside Add_RACW_Read_Attribute.
30313 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30315 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30319 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30320 sockets constant MSG_NOSIGNAL (Linux-specific).
30321 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30322 all Send operations.
30323 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30324 from trigerring SIGPIPE.
30325 Rename components to avoid clash with Ada 2005 possible reserved
30327 (Check_Selector): When the select system call returns with an error
30328 condition, propagate Socket_Error to the caller.
30330 2004-10-01 Jan Hubicka <jh@suse.cz>
30332 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

30338 instead do this at freeze time (we won't do it if there is an address
30340 Change "pragma inline" to "pragma Inline" in information and error
30342 Minor reformatting.
30344 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30345 right way of doing things after all.
30346 (Freeze_Entity): For object, set Is_Public for imported entities
30347 unless there is an address clause present.
30349 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30351 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30352 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30353 ensures proper handling of types with rep clauses, which might have
30354 their TYPE_SIZE set already.
30356 2004-09-21 Robert Dewar <dewar@gnat.com>
30358 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30359 packed array types in both little- and big-endian cases. This change
30360 ensures that we no longer count on the unused bits being initialized
30361 for such types (and in particular ensures that equality testing will
30362 only read the relevant bits).
30363 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30364 These changes mean that we no longer need to initialize small packed
30366 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30367 optimization to an LJM field as to its parent field.
30369 * ada-tree.h, trans.c, utils.c, utils2.c:
30370 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30372 2004-09-20 Jan Hubicka <jh@suse.cz>
30374 * utils.c (gnat_finalize): Remove.
30375 (end_subprog_body): Directly call cgraph_finalize_function;
30376 do not lower the nested functions.
30378 2004-09-20 Robert Dewar <dewar@gnat.com>
30381 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30382 if an address clause is present, since that means that the Import

30387 * 5tsystem.ads: Removed, no longer used.
30389 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30390 Zack Weinberg <zack@codesourcery.com>
30392 * ada-tree.def: Use tree_code_class enumeration constants
30393 instead of code letters.
30394 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30395 Update for new tree-class enumeration constants.

30411 an existing directory.
30412 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30413 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30414 Convert the result to File_Size.
30416 * prj.ads: (Project_Error): New exception
30418 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30419 Prj.Com, not from Osint.
30420 (Attrs, Package_Attributes): Tables moved to private part of spec
30421 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30423 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30424 Prj.Project_Error after call to Fail.
30425 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30426 Fail. Check that package name is not already in use.
30428 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30429 used by tools, not only by the project manager, and to indicate that
30430 exception Prj.Prj_Error may be raised in case of problem.
30431 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30433 (Attrs, Package_Attributes): Table instantiations moved from the body to
30434 the private part to be accessible from Prj.Attr.PM body.
30436 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30437 from new package Prj.Attr.PM.
30438 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30441 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30443 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check

30488 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
30489 pragmas recognized by GNAT.
30491 * gnat_rm.texi: Document pragma Detect_Blocking.
30493 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30494 raise Program_Error if called from a protected operation.
30496 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30497 the protected action nesting level.
30498 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30499 protected action nesting level.
30500 (Unlock): When pragma Detect_Blocking is active decrease the protected
30501 action nesting level.
30503 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30504 Protected_Action_Nesting.
30506 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30507 Common_ATCB record. It contains the dynamic level of protected action
30508 nesting for each task. It is needed for checking whether potentially
30509 blocking operations are called from protected operations.
30510 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30511 Detect_Blocking is active or not in the partition.
30513 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30514 raise Program_Error if called from a protected operation.

30523 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
30524 raise Program_Error if called from a protected operation, and increase
30525 the protected action nesting level.
30526 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
30527 Program_Error if called from a protected operation, and increase the
30528 protected action nesting level.

30534 the protected action nesting level.
30535 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
30536 Program_Error if called from a protected operation, and increase the
30537 protected action nesting level.

30541 active, raise Program_Error if called from a protected operation.
30542 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
30543 protected action nesting level.
30545 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30546 insertion of the statement raising Program_Error. The run time
30547 contains the required machinery for handling that.
30549 * sem_util.ads: Change comment associated to procedure
30550 Check_Potentially_Blocking_Operation.
30551 This procedure does not insert a call for raising the exception because
30552 that is currently done by the run time.
30554 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30556 * init.c: Add the global variable __gl_detect_blocking that indicates
30557 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30558 making the pragma available at run time.
30559 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30561 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30562 pragma Detect_Blocking is active.
30564 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30566 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30567 DB is found in the ali file. Any unit compiled with pragma
30568 Detect_Blocking active forces its effect in the whole partition.
30570 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30571 Detect_Blocking is active and delay is called from a protected
30574 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30575 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30576 Detect_Blocking is active (0 otherwise).
30577 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30578 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30581 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30583 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30584 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30587 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30588 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30589 Update API in placeholder implemetation of s-parint to reflect changes
30590 in distribution runtime library.
30592 * sem_ch3.adb (Expand_Derived_Record): Rename to
30593 Expand_Record_Extension.
30595 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30596 primitive operations of potentially distributed object types that have
30597 non-controlling anonymous access formals.
30599 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30601 New implementation of expansion for remote access-to-subprogram types,
30602 based on the RACW infrastructure.
30603 This version of sem_dist is compatible with PolyORB/DSA as well as
30606 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30607 Asynchrronous that applies to a remote access-to-subprogram type, mark
30608 the underlying RACW type as asynchronous.
30610 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30611 __gnat_using_gnu_linker to 1.
30613 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30614 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30615 GNAT.Perfect_Hash_Generators, and remove the empty

30620 * exp_ch3.adb (Expand_Derived_Record): Rename to
30621 Expand_Record_Extension.
30622 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30623 a component declaration must remain attached at that point in the
30624 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30625 It is therefore necessary to take a copy of the expression when building
30626 the corresponding assignment statement in the init proc.
30627 As a side effect, in the case of a derived record type, we now see the
30628 original expression, without any rewriting that could have occurred
30629 during expansion of the ancestor type's init proc, and we do not need
30630 to go back to Original_Node.
30632 * exp_ch3.ads (Expand_Derived_Record): Rename to
30633 Expand_Record_Extension.
30635 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30636 Returns the RACW type used to implement a remote access-to-subprogram
30638 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30639 New subprograms. Used to create a proxy tagged object for a remote
30640 subprogram. The proxy object is used as the designated object
30641 for RAS values on the same partition (unless All_Calls_Remote applies).
30642 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30643 System.Partition_Interface.Get_Unique_Remote_Pointer.
30644 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30645 Renamed from Add_RAS_*_Attribute.
30646 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30648 New implementation of expansion for remote access-to-subprogram types,
30649 based on the RACW infrastructure.
30651 * exp_dist.ads (Copy_Specification): Update comment to note that this
30652 function can copy the specification from either a subprogram
30653 specification or an access-to-subprogram type definition.
30655 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30657 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30658 in an instance, between an explicit subprogram an one inherited from a
30659 type derived from an actual.
30661 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30662 add a polling call if the subprogram is to be inlined by the back-end,
30663 to avoid repeated calls with multiple inlinings.
30665 * checks.adb (Apply_Alignment_Check): If the expression in the address
30666 clause is a call whose name is not a static entity (e.g. a dispatching
30667 call), treat as dynamic.
30669 2004-09-09 Robert Dewar <dewar@gnat.com>
30671 * g-trasym.ads: Minor reformatting
30673 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30679 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
30682 2004-09-09 Pascal Obry <obry@gnat.com>
30684 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30685 enable map file generation. Add the right option to generate the map
30686 file if Map_File is set to True.
30688 * gnatdll.adb (Gen_Map_File): New variable.
30689 (Syntax): Add info about new -m (Map_File) option.
30690 (Parse_Command_Line): Add support for -m option.
30691 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

30717 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30718 of variable length temporaries for function return now that the
30719 back-end and gigi support it.

30913 for a global aliased object with a variable size and an unconstrained
30914 nominal subtype, pretend there is no initializer if the one we have is
30915 incomplete, and avoid referencing an inexistant component in there. The

30943 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30944 discriminants that rename those of the parent, recover names of

30976 returning C.int, to avoid using a derived boolean type.
30978 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31007 ignore overflows on low and high bounds of an index to also account for
31008 differences in signedness between sizetype and gnu_index_subtype.
31009 These are as legitimate as the ones caused by a lower TYPE_PRECISION

34128 (Array_Type_Declaration): In case of components that are anonymous
34129 access types the level of accessibility depends on the enclosing type

34926 complete assignment subtree which is now unnecessary, as the expansion
34927 of inlined call has been improved to preserve a consistent assignment

35152 * sem_ch6.adb (Process_Formals): Carry out some static checks.
35153 (Set_Actual_Subtypes): Generate null-excluding subtype if the
35154 null-excluding part was present; it is not required to be done here in
35155 case of anonymous access types.
35156 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
35159 * sem_res.adb (Resolve_Actuals): Carry out some static check
35160 (Resolve_Null): Allow null in anonymous access
35162 * sinfo.adb: New subprogram Null_Exclusion_Present
35163 All_Present and Constant_Present available on access_definition nodes
35165 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
35166 object_declaration, derived_type_definition, component_definition,
35167 discriminant_specification, access_to_object_definition,
35168 access_function_definition, allocator, access_procedure_definition,
35169 access_definition, parameter_specification, All_Present and
35170 Constant_Present flags available on access_definition nodes.

35186 * sem_ch12.adb: Add comment for previous change
35188 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35190 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35191 executable name when not initialized. Otherwise, use its current value.
35193 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35194 initialize it to another executable name than the current one. This
35195 allows to configure paths for an executable name (gnatmake) different
35196 from the current one (gnatdist).
35198 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35200 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35201 current unit cannot be inlined if it appears in the body of a withed
35202 unit, to avoid order of elaboration problems in gigi.
35204 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35205 information for protected (wrapper) operation as well, to simplify gdb
35208 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35209 protected body, indicate that the entity for the generated spec comes
35210 from source, to ensure that references are properly generated for it.
35211 (Build_Body_To_Inline): Do not inline a function that returns a
35214 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35215 apply convention to homonyms that are declared explicitly.
35217 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35218 that renames an equality operator and the operands are overloaded,
35219 resolve them with the declared formal types, before rewriting as an
35222 2004-03-29 GNAT Script <nobody@gnat.com>
35224 * Make-lang.in: Makefile automatically updated
35226 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35228 * memtrack.adb: Log realloc calls, which are treated as free followed
35231 2004-03-25 Vincent Celier <celier@gnat.com>
35233 * prj-makr.adb (Process_Directories): Detect when a file contains
35234 several units. Do not include such files in the config pragmas or

35243 resolve links when computing the display names.
35245 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35247 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35248 attribute reference does not denote a subtype, it can be any
35249 expression that has a classwide type, potentially after an implicit
35250 dereference. In particular, the prefix can be a view conversion for
35251 a classwide type (for which Is_Object_Reference holds), but it can
35252 also be a value conversion for an access-to-classwide type. In the
35253 latter case, there is an implicit dereference, and the original node
35254 for the prefix does not verify Is_Object_Reference.
35256 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35257 conversion of a discriminant-dependent component of a mutable object
35260 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35262 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35263 inherited, has convention C, and has unconstrained array parameters,
35264 place the corresponding warning on the derived type declaration rather
35265 than the original subprogram.
35267 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35268 indication on renaming declaration, if formal has a box and actual
35271 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35272 determine whether to generate an implicit or explicit reference to
35273 the renamed entity.
35275 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35276 subprogram renaming comes from a defaulted formal subprogram in an
35279 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35281 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35282 value expressions to ensure that calls within a component definition
35283 will be checked (since those are evaluated during the record type's
35286 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35288 * s-tpobop.adb: Code clean up:
35289 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35305 * ali.ads: Fix Comment about Dynamic_Elab.
35307 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
35308 Has_RACW, Is_Generic, etc.)
35309 (Output_Object, Gnatls): Take into account ALI files not attached to
35312 2004-03-22 Vincent Celier <celier@gnat.com>
35314 * gprep.adb: Change all String_Access to Name_Id
35315 (Is_ASCII_Letter): new function
35316 (Double_File_Name_Buffer): New procedure
35317 (Preprocess_Infile_Name): New procedure

35327 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
35329 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35330 case when the source contains only comments.
35332 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35334 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35335 declaration for a child subprogram body that acts as a spec, indicate
35336 that the entity in the declaration needs debugging information.
35338 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35339 full view if the subtype is created for a constrained record component;
35340 gigi has enough information to construct the record, and there is no
35341 place in the tree for the declaration.
35343 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35344 serial number for the dummy body that is built for analysis, to avoid
35345 inconsistencies in the generation of internal names when compiling
35348 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35350 * sem_util.adb (Is_Object_Reference): A view conversion denotes an

35375 * gnat_ug.texi: Add info directory category and entry.
35376 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35377 gnat_ug_wnt.texi: Regenerate.
35379 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35381 * ada-tree.h: Update copyright notice.
35382 Minor reformatting.
35384 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35386 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35387 as regular exception objects and not as mere integers representing the
35388 condition code. The latter approach required some dynamics to mask off
35389 severity bits, which did not fit well into the GCC table based model.
35390 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35391 exception data objects. We don't it and it would conflict with the other
35392 external symbol we have to generate for such exceptions.
35394 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35395 the special code for VMS exceptions, since these are now represented
35396 as regular exceptions objects.
35398 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35400 * decl.c (debug_no_type_hash): Remove.

35402 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35404 2004-03-19 Laurent Guerby <laurent@guerby.net>
35406 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35407 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35409 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35411 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35412 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35413 (TYPE_RM_SIZE_INT): Directly use type.values.
35414 (TREE_LOOP_ID): Clean up check.
35415 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35416 TYPE_VALUES, not TYPE_FIELDS.
35417 * trans.c (convert_with_check): Delay access of bounds of basetype
35418 until sure is numeric.

35426 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35427 Specific.Set instead of direct call to e.g pthread_setspecific.
35429 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35431 * adaint.c: Update comments.
35433 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35434 GNATLIB_SHARED for FreeBSD.
35436 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35438 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35439 When needed (stack checking) the stack size is retrieved
35440 from the VxWorks kernel.
35442 * Makefile.in: Flag -nostdinc is required when building the run time
35443 for avoiding looking for files in the base compiler.
35444 Add the VxWorks specific version of the package body for
35445 System.Stack_checking.Operations (5zstchop.adb).
35447 * Make-lang.in: Add the object file for
35448 System.Stack_Checking.Operations.
35450 * Makefile.rtl: Add object file for the package
35451 System.Stack_Checking.Operations.
35453 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35455 * s-stache.ads, s-stache.adb: Move the operations related to stack
35456 checking from this package to package System.Stack_Checking.Operations.
35457 This way, stack checking operations are only linked in the final
35458 executable when using the -fstack-check flag.
35460 2004-03-18 Doug Rupp <rupp@gnat.com>
35462 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35465 * 5qsystem.ads, 5xcrtl.ads: New files.
35467 2004-03-18 Vincent Celier <celier@gnat.com>

35471 * prj-env.adb (Source_Paths, Object_Paths): New tables.
35472 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35473 the procedures Add_To_Path_File.
35474 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35475 making sure that each directory is present only once and, for object
35476 dirs, when a directory already present is added, the duplicate is
35477 removed and the directory is always put as the last in the table.
35478 Write the path files at the end of these accumulations.
35480 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35481 Files_Htable for all sources.
35483 * prj-proc.adb (Process): Remove restrictions between not directly
35484 related extending projects.
35486 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

35492 parameter Trusted_Mode.
35494 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35496 * scn.adb (Determine_License): Take into account a degenerated case
35497 when the source contains only comments.
35499 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35501 * sem_warn.adb (Check_References): For a warning on a selected
35502 component that does not come from source, locate an uninitialized
35503 component of the record type to produce a more precise error message.
35505 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35507 * 3zsoccon.ads: Fix multicast options.
35509 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35512 2004-03-15 Robert Dewar <dewar@gnat.com>
35514 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35515 pragma used for a private type.
35517 * lib-xref.adb (Generate_Reference): Do not generate warning if
35518 reference is in a different unit from the pragma Unreferenced.
35520 * 5vtpopde.adb: Minor reformatting
35521 Fix casing of To_Task_ID
35523 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35524 flag if we have an unchecked conversion to an access type in the same
35527 2004-03-15 Geert Bosch <bosch@gnat.com>
35529 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35530 imaginary parts, use Double precision throughout.
35532 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35533 we want to be able to compile run-time with -gnata for testing, but
35534 this may also be instantiated in user code that is compiled with -gnata.
35536 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35538 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35539 codes. Having a separate type for this is useful to enforce consistency
35540 throughout the various run-time units.
35541 (Exception_Data): Use Exception_Code for Import_Code.
35543 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35544 Natural and Integer in various places.

35546 with the severity bits masked off.
35547 (Register_VMS_Exception): Handle the additional exception data pointer

35551 component, now reflected by an exported accessor.
35552 (is_handled_by): New routine to compute whether the propagated
35553 occurrence matches some handler choice specification. Extracted out of
35554 get_action_description_for, and expanded to take care of the VMS
35556 (get_action_description_for): Use is_handled_by instead of an explicit
35557 complex condition to decide if the current choice at hand catches the
35558 propagated occurrence.
35560 * raise.h (Exception_Code): New type for C.
35562 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35563 System.Standard_Library.Exception_Code, to allow references from the
35564 pragma import/export expander.
35566 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35567 New accessors to allow easy access to GNAT exception data
35569 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35570 redundant Handled_By_Others component, helper for the personality
35571 routine which will now be able to call the appropriate exception data
35574 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35575 component of Standard_Exception_Type to be the closest possible to
35576 Exception_Code in System.Standard_Library, that we cannot get at this
35577 point. Expand a ??? comment to notify that this type node should
35578 probably be rewritten later on.
35580 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35581 registration call to include a pointer to the exception object in the
35584 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35585 instead of int and explicit bitmasks.
35587 2004-03-15 Vincent Celier <celier@gnat.com>
35589 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35590 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35592 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35593 longer needed now that it is in the spec of
35594 System.Tasking.Task_Attributes.
35596 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35598 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35600 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35602 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35603 taken care of in Scan_Make_Arg.
35604 (Scan_Make_Arg): Add the executable suffix only if the argument
35605 following -o, in canonical case, does not end with the executable
35606 suffix. When in verbose mode and executable file name does not end
35607 with executable suffix, output the executable name, in canonical case.
35609 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35610 to avoid warnings when instantiating Ada.Task_Attributes.
35613 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35614 in the correct order.
35616 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35617 redirect standard output and error to a file for the invocation of the
35618 compiler, then read the file.
35620 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
35621 directory, instead of the Value.
35622 (Find_Source_Dirs): Remove useless code & comments.
35624 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35626 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35627 tagged type is inherited, and the parent operation is not frozen yet,
35628 force generation of a freeze node for the inherited operation, so the
35629 corresponding dispatch entry is properly initialized.
35630 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35631 when looking for user-defined equality operation.
35633 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35634 boolean when locating primitive equality of tagged component.
35636 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
35637 bit-aligned field and the right-hand side a string literal, introduce
35638 a temporary before expanding assignment into a loop.
35640 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35641 priority in full, to ensure that any expanded subepxressions of it are
35642 elaborated in the scope of the init_proc.
35644 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35645 after object declaration, skipping over code that may have been
35646 generated for validity checks.
35648 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35649 discriminants, ignore the known discriminants of its full view, if
35650 any, to check legality.
35652 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained

36580 checks for bitfield creation are triggered.
36581 (finish_record_type): During last pass over the fields, clear
36582 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37041 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37042 N_String_Literal node always references an E_String_Literal_Subtype
37043 entity. This may not be true in the future.
37044 (Possible_Bit_Aligned_Component): Move processing of
37045 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37047 * exp_ch6.adb (Expand_Thread_Body): Pick up

37052 (Type_May_Have_Bit_Aligned_Components): New function.

37092 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37093 ineffective elaborate all pragmas on non-visible packages (this
37094 happened when a renamed subprogram was called). Now the elaborate all
37095 always goes on the package containing the renaming rather than the one
37096 containing the renamed subprogram.
37098 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37099 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37124 * make.adb (Gnatmake): Special process for files to compile/check when
37125 -B is specified. Fail when there are only foreign mains in attribute

37160 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve

37203 pure, emit warning.

37313 * 5zinit.adb: Clean up.
37315 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37316 to __gnat_map_signal, imported from init.c to support
37317 signal -> exception mappings that depend on the vxWorks version.
37320 Created and exported __gnat_map_signal to support signal -> exception
37321 mapping that is dependent on the VxWorks version.

37354 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37355 bounds of a loop, create a separate block in order to generate proper
37356 cleanup actions to prevent memory leaks.
37358 * sem_res.adb (Resolve_Call): After a call to
37359 Establish_Transient_Scope, the call may be rewritten and relocated, in

37378 2003-12-08 Robert Dewar <dewar@gnat.com>
37380 * 7sintman.adb: Minor reformatting
37382 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37383 standard linker options to get standard libraries linked. We now plan
37384 to provide dummy versions of these libraries to match the appropriate
37385 configurable run-time (e.g. if a library is not needed at all, provide
37386 a dummy empty library).
37388 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37389 options (-L parameters and standard libraries). What we plan to do is
37390 to provide dummy libraries where the libraries are not required.
37392 * gnatbind.adb: Minor comment improvement

37404 of aggregate with default initialized components.
37405 (Has_Default_Init_Comps): Improve implementation to recursively check
37406 all the present expressions.
37408 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37409 to indicate that the initialization call corresponds to a
37410 default-initialized component of an aggregate.
37411 In case of default initialized aggregate with tasks this parameter is
37412 used to generate a null string (this is just a workaround that must be
37413 improved later). In case of discriminants, this parameter is used to
37414 generate a selected component node that gives access to the discriminant
37417 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37418 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37419 allocated aggregates with default-initialized components.

37464 Process nodes N_Comment.
37466 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37467 without comments and there are some comments, set the flag
37468 Unkept_Comments to True.
37469 (Scan): If there are comments, set the flag Unkept_Comments to True and
37470 clear the comments.

37500 Comment_Id and set Token to Tok_Comment when scanning a comment.
37501 (Set_Comment_As_Token): New procedure
37503 * sinput-p.adb: Update Copyright notice
37504 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37510 Correct typo in comment
37511 (Resolve_Aggregate): In case of array aggregates set the estimated
37512 type of the aggregate before calling resolve. This is needed to know
37513 the name of the corresponding IP in case of limited array aggregates.
37514 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37515 in case of default initialized array components.
37517 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37537 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37538 they are automatically generated by Make-lang.in and cause nothing but
37539 maintenance troubles.
37541 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37543 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37557 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37558 to ensure that the kernel fills in the interrupted context structure
37559 before calling a signal handler, which is necessary to be able to
37560 unwind past it. Update the copyright notice.
37562 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37564 * a-elchha.ads: New file.

37651 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37654 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37655 is legal in an instance, because legality is cheched in the template.

37676 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37677 so that the debugger can reliably access the value of the parameter,

40581 xtreeprs.adb: Correct statements in comments about maintainership
40584 2002-09-23 Zack Weinberg <zack@codesourcery.com>
40586 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.

41206 2002-01-30 Richard Henderson <rth@redhat.com>
41208 * trans.c (tree_transform) [N_Loop_Statement]: Use
41209 expand_exit_loop_top_cond.

41227 (general) Add @./@: where approriate, and two spaces after the
41228 full stop at the end of a sentence. Use @samp markup when
41229 referring concrete lexical entities (keywords, attribute names
41230 etc.), and @syntax for ARM grammar elements. Use @r for English

41246 function approach did not work well because of a side effect (the
41247 function call could reallocate the table which was being indexed
41248 using its result). Fixes ada/4851.

41309 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no

41312 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41314 * s-taprob.adb: Minor clean ups so that this unit can be used in

41615 2001-12-17 Laurent Pautet <pautet@gnat.com>
41618 Fix comment of Shutdown_Socket and Close_Socket. These functions
41619 should not fail silently because if they are called twice, this
41620 probably means that there is a race condition in the user program.
41621 Anyway, this behaviour is consistent with the rest of this unit.
41622 When an error occurs, an exception is raised with the error message
41623 as exception message.

41776 reference nodes, since this field is used in such nodes.

42962 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42963 instead of simple checksum.
42964 (CRC_Match): new function.
42965 (CRC_Error): new constant.
42967 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42968 a CRC now and not a simple checksum. A CRC uses lower-case hex
42969 letters, fixes ambiguity in parsing.
42971 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
42972 is what this variable will store.
42974 * bcheck.adb: Change reference to chechsum in comments by CRC.
42975 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42976 rename All_Checksum_Match to All_CRC_Match. Change due to API
42977 renaming since now GNAT does not use a simple checksum but a
42978 CRC using GNAT.CRC32.
42980 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42981 now and not anymore a simple checksum.

43018 Update comments for the CRC.
43020 * types.adb (Hex): Use lowercase for the letter part.
43022 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43023 for a word. This is currently used only for CRC. In previous version,
43024 the checksum was using a representation with all letter being
43025 upper-case. With the new implementation (using CRC) we do not remove
43026 the 32th bit of the CRC, so we can have an upper-case starting letter
43027 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43028 It is ambigous since the CRC was optional and could be followed by
43029 options like EB, EE. So now this routines uses lower-case letter for
43030 the hexadecimal representation. Strange enough only lower case letters
43031 where checked in Scan_ALI (even if this was not a possible case).
43033 * gnatvsn.ads (Library_Version): changed to 3.15a.
43035 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43038 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43041 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43042 Add 2001 to copyright notice
43043 (Accumulate_Checksum): Modify to use System.CRC32.
43045 * ali-util.ads: Redo changes of previous revision to continue to use
43046 the word Checksum. Add 2001 to copyright notice.
43048 * ali.adb: Undo some of previous changes, not needed.
43049 Keep the change for lower case letters in the checksum.
43051 * ali.ads: Undo previous change not needed.
43053 * bcheck.adb: Undo most of previous change, not needed.
43054 But do use Checksums_Match for checksum comparison.

43057 But do use Checksums_Match for comparing checksums.
43059 * lib-load.adb: Undo previous change, not needed.
43061 * lib-writ.adb: Undo previous change, not needed.
43063 * lib-writ.ads: Document that checksums use lower case,

43081 * sinput.adb: Undo previous change, not needed.
43083 * sinput-l.adb: Undo previous change, not needed.
43085 * sinput.ads: Undo previous change, not needed. Keep only comment
43086 on new checksum algorithm
