1700 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1701 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3895 Add missing escaping of all-caps word 'CPP' in error messages.
3896 (Build_Discriminated_Subtype): Do not inherit representation clauses
3897 from parent type if subtype already carries them, because they are
3898 inherited earlier during derivation and already include those that may
3899 come from a partial view.

3937 operation of an RACW stub type (these primitives are only executed
3938 through dispatching, never through static calls).
3939 (Collect_Interps): When only one interpretation has been found, set N's
3940 Entity and Etype to that interpretation, otherwise Entity and Etype may
3941 still refer to an interpretation that was ignored by Add_One_Interp,
3942 in which case would end up with being marked as not overloaded but with
3943 an Entity attribute not pointing to its (unique) correct interpretation.

8203 WITH clause on a private sibling.
8204 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8205 child unit is a renaming, create an implicit with_clause on that
8206 parent, and not on the unit it renames, to prevent visibility errors

8310 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8311 Timed_Entry_Call): Analyze the triggering statement as the first step of
8312 the processing. If this is a dispatching select, postpone the analysis
8313 of all select statements until the Expander transforms the select. This

8315 replicated some of the select statements. In case the Expander is
8316 disabled, perform regular analysis.
8317 (Check_Triggering_Statement): New routine.
8318 (Analyze_Requeue): Exclude any interpretations that are not entries when
8319 checking overloaded names in a requeue. Also test type conformance for

8889 variables modified calls where they are IN OUT or OUT parameters and
8890 the resulting values are not subsequently referenced. In a few cases,
8891 we also remove redundant code found by the new warnings.
8893 * ug_words, vms_data.ads, usage.adb, sem_util.adb, sem_util.ads,
8894 sem_warn.adb, sem_warn.ads, sem_res.adb, sem_ch7.adb, sem_ch8.adb,

8896 sem_ch11.adb, exp_ch6.adb, einfo.ads, einfo.adb: implement a new
8897 warning controlled by -gnatw.o that warns on cases of out parameter
8898 values being ignored.
8900 2007-10-15 Geert Bosch <bosch@adacore.com>
8902 * adaint.c, socket.c, cal.c: Initial port to arm-mentor-nucleus.
8904 * expect.c: Initial port to arm-mentor-nucleus.
8905 Use kill for __gnat_kill() on VMS.

8909 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
8911 (Xref_Record): Change type for Line, since in the case of a reference to
8912 a predefined entity (as happens for array index types), the line is set
8914 Add support for parsing multiple array index types info, or
8915 multiple inherited interfaces info. This information cannot be stored
8916 in Xref_Entity_Record, which only supports a single instance of Tref_*,
8917 and is therefore stored in the list of references instead. It has a
8918 special treatement later on in tools that use this information.
8920 2007-10-15 Tristan Gingold <gingold@adacore.com>
8922 * debug.adb: Document use of -gnatd.a and -gnatd.I
8924 * layout.adb: On OpenVMS -gnatd.a disables alignment optimization.

8928 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
8929 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
8930 care of access to class-wide interface types plus removal of bizarre
8931 conversion of tagged object to access type (reported by Gary
8932 Dismukes). After this patch there is no need to perform any
8933 additional management on these nodes in Expand_Interface_Actuals.
8935 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8936 that handles use of 'Access and 'Unchecked_Access applied to
8937 actuals covering interface types. Such code is now
8938 centralized in Expand_N_Attribute_Reference.
8940 2007-10-15 Ed Schonberg <schonberg@adacore.com>
8942 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
8943 of tagged types whose ultimate ancestor is a CPP type.
8944 (Freeze_Array_Type): For a packed array type, generate an initialization
8945 procedure if the type is public, to handle properly a client that
8946 specifies Normalize_Scalars.
8948 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8950 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs
8951 inside a generic body, retrieve the full view of the entry family

8967 * sem_case.adb, sem_ch13.adb, lib-sort.adb: Replace use of Heap_Sort_A
8968 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
8969 the generic Heap_Sort_G, in order to avoid trampolines.
8971 2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>
8972 Jose Ruiz <ruiz@adacore.com>
8974 * vx_stack_info.c: New file.
8976 * i-forbla-unimplemented.ads: New file.
8978 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
8979 for unsupported configurations; use it on VMS targets instead of the
8981 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
8982 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
8983 used by VxWorks targets to have access to task-specific data and be
8984 able to extract the stack boundaries for stack checking.
8985 Use system-vms-ia64.ads on ivms.
8987 * Make-lang.in: Update dependencies.
8989 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
8992 2007-10-15 Vincent Celier <celier@adacore.com>

9006 95 reserved word in its name.
9007 (Process_Project_Level_Array_Attributes): Process new attribute
9008 Runtime_Library_Dir.
9010 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9011 config project against the user project names.

9026 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9028 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9029 association for an access component, add an association with null as
9030 the expression. Remove testing for array subtypes and the setting in
9031 that case of Ctyp to the array component type, which prevented proper
9032 inclusion of an association for null-initialized arrays. Collapse
9033 condition that tests for array subtypes into just a test of
9034 Is_Partially_Initialized_Type (which already covers arrays anyway).
9036 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9038 * sem_ch12.adb: Minor code reformatting.
9039 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to
9040 find the parent package which may have been hidden by local
9043 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9045 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9046 flag of derived concurrent types, taking into account the flag setting
9047 on the parent subtype and any new set of discriminants.
9049 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9051 * sem_ch4.adb: Minor code and comment reformatting.
9052 (Analyze_Allocator): When the designated type of an unconstrained
9053 allocator is a record with unknown discriminants or an array with
9054 unknown range bounds, emit a detailed error message depending on the
9055 compilation mode and whether the designated type is limited.

9070 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9072 * sem_disp.adb (Find_Controlling_Arg): Examine the call node before
9073 examining its original form, to handle properly operator calls that
9074 have been rewritten.

9109 * gnat_ugn.texi: Add documentation for switches --version and --help
9110 for the GNAT tools gnatbind, gnatlink, gnatmake, gnatchop, gnatname,
9111 gnatxref, gnatfind, gnatls, and gnatclean.

9126 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
9129 Update documentation to note that OpenVMS 8.3 or later must be used
9130 to generate g-soccon-vms.ads.
9132 * atree.adb: Add ??? comment
9134 * exp_util.adb: Minor reformatting.

9186 * trans.c (number_files): New global variable.
9187 (gigi): Rename and change type of number_units parameter, change
9188 type of file_info_ptr parameter.
9189 If mapped location support is enabled, create the isomorphic mapping
9190 between source files and line maps.
9191 (Sloc_to_locus): If mapped location support is enabled, translate
9192 source location into mapped location.
9193 (annotate_with_node): Rename into set_expr_location_from_node.

9219 * a-calend-vms.adb, a-calend.adb:
9220 Add a section on leap seconds control along with two entities used to
9221 enable and disable leap seconds support. The array Leap_Second_Times is
9222 now constant and contains hard time values pre-generated. Remove
9223 all elaboration code used to populate the table of leap seconds.
9226 Add entity Leap_Seconds_Support to the list of global run-time variables
9227 along with a comment on its usage and values.
9228 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9230 or one (enabled) depending on the presence of binder switch "-y".
9231 (Gen_Adainit_C): Add code to generate the declaration of external int
9232 __gl_leap_seconds_support. Set is value to zero (disabled) or one

9284 Eric Botcazou <ebotcazou@adacore.com>
9287 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9288 indirection added to the HT_Link component of the TSD. This is required
9289 to statically allocate the TSD.
9292 Minor reordering of the declarations in the private part. Required to
9293 add a level of indirection to the contents of the TSD component HT_Link.
9294 This is required to statically allocate the TSD.
9296 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9297 Is_Statically_Allocated set from constant objects.

9308 purpose Make_DT now declares a separate object that stores the
9309 HT_Link value, and initializes the TSD component with the address
9310 of this new object. The addition of this level of indirection is
9311 required to statically allocate the TSD because the TSD cannot
9312 have variable components.
9313 (Expand_Interface_Conversion): Improve the expanded code.
9314 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9316 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9317 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9318 if we are building static dispatch tables then we must not generate
9319 extra code to register the primitive because the dispatch table will
9320 be built at the end of the library package; otherwise we notify that
9321 we cannot build the static dispatch table.
9323 2007-09-26 Robert Dewar <dewar@adacore.com>

9343 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9344 associated with interface types.
9345 Extensive comment fixes regarding flags that appear in all entities. The
9346 documentation is now consistent for all such flags (there were a number
9347 of errors in the documentation in this regard).
9349 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9351 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9352 of these procedures are passed a function call that already has
9353 build-in-place actuals (testing new flag
9354 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9355 the case where processing continues.
9356 (Expand_Call): If the call is generated from a thunk body then we
9357 propagate the extra actuals associated with the accessibility
9358 level of the access type actuals.
9360 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9361 of each extra formal of a protected operation to reference the
9362 corresponding extra formal of the subprogram denoted by the
9363 operation's Protected_Body_Subprogram.
9365 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9366 N_Function_Call nodes.
9368 2007-09-26 Robert Dewar <dewar@adacore.com>
9370 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9372 * debug.adb: Add d.s flag.

9376 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9377 debug variable so that it won't be initialized when pragma
9378 Initialize_Scalars is in effect.
9380 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9382 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9383 initialization of a full view. This is moved to
9384 Analyze_Package_Specification.
9386 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9387 preelaborable initialization of a full view in entity loop.
9388 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9389 its child units are use-visible only if they are visible child units.
9391 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9392 whether an expression can be used within a type declaration that
9393 requires preelaborable init.
9394 (Check_Components): Replace inline code that does partial checking for
9395 preelaborable default expressions with call to
9396 Is_Preelaborable_Expression.
9397 (Has_Preelaborable_Initialization): In the case of a generic actual
9398 subtype, (that is, Is_Generic_Actual is True), return the result of
9399 applying Has_Preelaborable_Initialization to the generic actual's base
9402 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9404 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9405 call to Jan_1_Day _Of_Week to optimize its performance.
9406 (Is_Leap): Move the routine to the scope of Week_In_Year.
9407 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9408 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9409 avoids calling Time_Of and Split, thus making it more efficent.
9410 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9412 * g-calend.ads (Week_In_Year): Change comment to reflect new
9415 2007-09-26 Emmanuel Briot <briot@adacore.com>
9417 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9418 Command_Line): New types
9419 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9420 support for defining how switches can be grouped on a command line (as
9421 is the case for -gnatw... for GNAT), and how simple switches can be
9422 used as aliases for more complex switches (-gnatwa is same as
9424 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9425 (Start, Current_*): New subprograms
9426 Added support for parsing an array of strings in addition to the real
9428 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9429 be moved from the body to the private part of the spec.
9430 (*): All subprograms now have an extra parameter with default value to
9431 specify which parser should be used. For backward compatibility, it
9432 defaults to parsing the command line of the application. They were also
9433 modified to properly handle cases where each of the argument does not
9434 start at index 1 (which is always true for Ada.Command_Line, but not
9435 when processing any Argument_List).
9436 (Free): New subprogram
9437 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9438 Argument): New subprograms
9439 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9440 special characters like ':', '=',... are now handled in a single place,
9441 which makes the code more extensible eventually.
9442 (Getopt, Full_Switch): When the switch was returned as part of the
9443 special character '*', make sure it is prepended by the switch character
9444 ('-' in general), so that the application knows whether "foo" or "-foo"
9445 was specified on the command line.
9447 2007-09-26 Florian Villoing <villoing@adacore.com>
9449 * g-dirope.adb (Remove_Dir): In case we are removing directories
9450 recursively, make sure that if an exception is raised during the
9451 processing, the current working directory is reset to its initial
9452 value before propagating the exception.
9454 2007-09-26 Vincent Celier <celier@adacore.com>
9456 * gnatbind.adb: If there are several ALI files specified and there is
9457 a main program to bind, the first ALI is expected to contain the main
9458 subprogram and the names of the binder generated files will be derived
9459 from the first ALI file name.
9460 (Gnatbind): Fix insertion character in invocation of Error_Msg
9462 2007-09-26 Vincent Celier <celier@adacore.com>
9464 * gnatcmd.adb (Check_Files): Do not include sources that have been

9470 information about each of its index types, following the type
9471 reference for its component type.
9473 2007-09-26 Vincent Celier <celier@adacore.com>

9501 attributes for gprbuild. No impact on GNAT tools.
9503 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

9505 (Recursive_Process): Make a full copy of packages inherited from project
9506 being extended, instead of a shallow copy.
9507 (Process_Project_Tree_Phase_1): New procedure

9509 (Process): Implementation now uses the two new procedures
9511 * prj-util.adb (Executable_Of): Get the suffix and the default suffix

9838 Thomas Quinot <quinot@adacore.com>
9840 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9841 create an abstract subprogram in the case of 'Input. For 'Output we now
9842 create a real spec/body when the type is abstract, since it can
9843 potentially be called.
9844 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9845 body for 'Output when the type is abstract (only the creation of the
9846 body for 'Input is excluded when the type is abstract).
9847 (Stream_Operation_OK): Add an additional condition in the return
9848 statement, so that False will be returned for TTS_Stream_Input if the
9849 associated tagged type is an abstract extension. Add comments for
9851 (Expand_N_Object_Declaration): For the case of a shared passive
9852 variable, insert init proc call only after the shared variable
9853 procedures have been processed, because the IP call needs to undergo
9854 shared passive variable reference expansion, which requires these
9855 procedures to be available (and elaborated).
9857 2007-09-10 Vincent Celier <celier@adacore.com>
9859 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove

9862 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9864 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
9865 given a box association, the type of the component is discriminated,
9866 and the value of the discriminant is the discriminant of the enclosing
9867 type, retrieve its value from the aggregate itself, where it must have
9870 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9871 to remove other spurious ambiguities on arithmetic operations involving
9872 literals and addresses, on systems where Address is a visible integer
9873 type, when the operator is called in functional notation.
9874 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9875 is legal when the types match, even if the operation is currently
9878 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9880 * sem_ch12.adb (Build_Local_Package): A formal package with no
9881 associations is legal if all formals have defaults. It is not

10000 (Write_Entity_Flags): Write the status of flag Is_Raised.
10001 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10002 spurious ambiguities when integer literals appear in the context of an
10003 address type that is a visible integer type.
10005 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10006 exceptions never being raised.
10007 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10010 2007-08-31 Javier Miranda <miranda@adacore.com>
10012 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise

10023 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10024 library-level package renaming, pass the declaration associated with
10025 the renaming's special debug variable to Qualify_Entity_Names to ensure
10026 that its encoded name is properly qualified.
10028 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10029 occurring in the list of entities to qualify, and do not attempt to
10030 traverse an entity list in that case. Variables associated with
10031 ` library-level package renamings can now occur in the table.
10033 * exp_dbug.ads: Revise documentation of the encoding for renaming
10036 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10039 access type points to an unconstrained array.
10041 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10043 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10046 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

10050 to include loop parameters.
10051 (Valid_Conversion): Avoid generation of spurious error message.

10055 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10056 concatenations of string literals into a single literal, in order to
10057 avoid very deep recursion in the front end, which was causing stack
10060 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10061 string, and the right operand is a string literal (the case of "" &
10062 "..."), optimize by avoiding copying the right operand -- just use the
10063 value of the right operand directly.
10065 * stringt.adb (Store_String_Chars): Optimize by growing the
10066 String_Chars table all at once, rather than appending characters one by
10068 (Write_String_Table_Entry): If the string to be printed is very long,
10069 just print the first few characters, followed by the length. Otherwise,
10070 doing "pn(n)" in the debugger can take an extremely long time.
10072 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10073 Store_String_Char with Store_String_Chars.

10092 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10093 flag, for effiency. It is called when analyzing arithmetic operators
10094 and also for actuals in calls that are universal_integers. The flag is
10095 set for the predefined type address, and for any type or subtype
10098 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10099 Universal_Integer, when the formal is a descendent of address and the
10100 call appears in user code.
10101 (Analyze_Selected_Component): if the prefix is a private extension, the
10102 tag component is visible.

10165 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10167 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10168 associated with Standard_Debug_Renaming_Type, to be used as the type of
10169 the special variables whose names provide debugger encodings for
10170 renaming declarations.
10172 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10173 (Set_Debug_Renaming_Link): Change to set Node25.

10180 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10181 and literal with creation of a variable of type
10182 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10183 and the entity of the renaming declaration.
10184 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10185 part of the name of a variable that has a Debug_Renaming_Link.
10187 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10188 special type to be associated with variables that provide debugger

10192 Ed Schonberg <schonberg@adacore.com>
10193 Javier Miranda <miranda@adacore.com>
10195 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10196 ancestor part given by an aggregate to test for an unchecked conversion,
10197 since this can occur in some cases when the ancestor part is a function
10198 call, and we don't want to fall into the recursive call to this
10199 procedure in that case.
10201 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10202 stream attributes on limited types to account for user-specified
10203 attributes as well as whether Input (resp. Output) becomes available
10204 due to Read (resp. Write) being available for the type. Change Boolean
10205 variable to the more accurate name
10206 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10207 double-"not" predicate at beginning of return statement to more
10208 understandable form.
10210 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10211 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10212 in a block statement and use that as the first statement of the
10213 expanded return rather than incorrectly using the handled sequence as
10214 the first statement.
10216 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10217 operation, generate an explicit freeze node for it rather than
10218 generating extra formals, to ensure that gigi has the proper order of
10219 elaboration for anonymous subtypes in the signature of the subprograms.
10220 (Build_In_Place_Formal): Move assertion to beginning of loop.
10221 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10222 applied to a function call (occurs for some cases of 'Input).
10223 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10224 applied to a function call (occurs for some cases of 'Input).
10226 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10227 2005, generate an extended return statement enclosing the result object
10230 * freeze.adb (Freeze_Record_Type): Extend the current management of
10231 components that are access type with an allocator as default value: add
10232 missing support to the use of qualified expressions of the
10233 allocator (which also cause freezing of the designated type!)
10234 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10235 dispatching operation, since extra formals may be needed by calls to
10236 build-in-place functions (such as stream 'Input).
10238 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10239 formals for 'Constrained and accessibility level in the case of a
10240 predefined dispatching operation.
10242 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10243 point, no need to find the parent node.
10245 2007-08-16 Javier Miranda <miranda@adacore.com>
10247 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10248 and entry barriers.
10250 2007-08-16 Javier Miranda <miranda@adacore.com>
10252 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10253 is not really required and can introduce regression with the debugger.
10254 The original problem is fixed with the patch written for checks.adb.
10256 2007-08-16 Thomas Quinot <quinot@adacore.com>
10258 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10265 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10266 Including_Non_Switch set to False.
10268 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10269 parameter Including_Non_Switch, defaulted to True. When
10270 Including_Non_Switch is False, options that are not switches and
10271 appear as relative path are not converted to absolute paths.
10273 2007-08-16 Nicolas Roche <roche@adacore.com>
10275 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10283 currently inspected is a selected component, retrieve the entity of
10285 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10286 from the immediate ancestor of Main_Unit_Entity.
10287 (Install_Limited_Withed_Unit): Do not install the limited view of
10288 package P if P is reachable through an ancestor chain from package C
10289 and C also has a with clause for P in its body.
10290 (Has_Limited_With_Clause): New routine.
10291 (Has_With_Clause): New routine.
10293 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10295 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10296 generic for an enclosing instance is a global reference, even though
10297 its scope is the enclosing instance.
10299 2007-08-16 Gary Dismukes <dismukes@adacore.com>

10323 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10324 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10325 the statement which is being resolved comes from a predefined library
10326 unit, all non-predefined library interpretations are skipped.
10327 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10328 but the "&" is user defined, give an error, because the folding would

10332 the parser has folded a long sequence of concatenations of string
10335 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10336 and "JMP_BUF" variables as artificial.
10337 (N_String_Literal): Do not use alloca for very long string literals. Use
10338 xmalloc/free instead. Otherwise the stack might overflow.

10385 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10386 Suppress unmodified in-out parameter warning in some cases
10387 This patch is a also fairly significant change to the way suppressible
10388 checks are handled.
10390 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10391 needed for access to concurrent record types generated by the expander.
10392 (Generate_Range_Check): When generating a temporary to capture the
10393 value of a conversion that requires a range check, set the type of the
10394 temporary before rewriting the node, so that the type is always
10395 properly placed for back-end use.
10396 (Apply_Float_Conversion_Check): Handle case where the conversion is
10398 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10406 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10407 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10408 tests optimized out.
10410 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10411 (Get_Allocator_Final_List): For the case of an anonymous access type
10412 that has a specified Associated_Final_Chain, do not go up to the
10414 (Expand_N_Type_Conversion): Test for the case of renamings of access
10415 parameters when deciding whether to apply a run-time accessibility
10417 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10418 aggregate code before allocator, and ahead of declaration for
10419 temporary, to prevent access before elaboration when the allocator is
10420 an actual for an access parameter.
10421 (Expand_N_Type_Conversion): On an access type conversion involving an
10422 access parameter, do not apply an accessibility check when the
10423 operand's original node was an attribute other than 'Access. We now
10424 create access conversions for the expansion of 'Unchecked_Access and
10425 'Unrestricted_Access in certain cases and clearly accessibility should
10426 not be checked for those.
10428 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10429 includes a type conversion of a packed component that has been expanded,
10430 recover the original expression for the object, and use this expression
10431 in the post-call assignment statement, so that the assignment is made
10432 to the object and not to a back-end temporary.
10433 (Freeze_Subprogram): In case of primitives of tagged types not defined
10434 at the library level force generation of code to register the primitive
10435 in the dispatch table. In addition some code reorganization has been
10436 done to leave the implementation clear.
10437 (Expand_Call): When expanding an inherited implicit conversion,
10438 preserve the type of the inherited function after the intrinsic
10439 operation has been expanded.
10441 * exp_ch2.ads, exp_ch2.adb
10442 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10443 of an entry formal appearing in an assignment statement does not assign
10445 (Expand_Current_Value): Instead of calling a routine to determine
10446 whether the prefix of an attribute reference should be optimized or
10447 not, prevent the optimization of such prefixes all together.
10449 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10450 component whose prefix is known to be of an access type is an implicit
10451 dereference and does not assign to the prefix.

10454 Robert Dewar <dewar@adacore.com>
10456 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10457 itype is visited, make an entry into table to link associated node and
10459 Add comments and correct harmless error in Build_NCT_Hash_Tables
10460 (Array_Aggr_Subtype): Associate each itype created for an index type to
10461 the corresponding range construct, and not to the aggregate itself. to
10462 maintain a one-to-one correspondence between itype and its associated
10463 node, to prevent errors when complex expression is copied.
10464 Fix mishandling of multiple levels of parens
10466 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10467 treatment of limited views uniform for all visible declarations in a
10468 limited_withed package.
10469 (New_Copy_Tree): If hash table is being used and itype is visited,
10470 make an entry into table to link associated node and new itype.
10471 (Resolve_Record_Aggregate): Do not add an others box association for a
10472 discriminated record component that has only discriminants, when there
10473 is a box association for the component itself.
10475 * par-ch4.adb: Fix mishandling of multiple levels of parens

10513 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10514 to make treatment of limited views uniform for all visible declarations
10515 in a limited_withed package.
10516 Improve warnings for in out parameters
10517 (Set_Related_Interaface/Related_Interface): Allow the use of this
10518 attribute with constants.
10519 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10520 Warn on duplicate pragma Preelaborable_Initialialization
10522 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10523 generation of a freezing node to ensure proper management of null
10524 excluding access types in the backend.
10525 (Create_Extra_Formals): Test base type of the formal when checking for
10526 the need to add an extra accessibility-level formal. Pass the entity E
10527 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10528 originally being done in a couple of cases), to ensure that the
10529 Extra_Formals list gets set on the entity E when the first entity is
10531 (Conforming_Types): Add missing calls to Base_Type to the code that
10532 handles anonymous access types. This is required to handle the
10533 general case because Process_Formals builds internal subtype entities
10534 to handle null-excluding access types.
10535 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10536 functions that need it, even when not marked Requires_Overriding.
10537 Improve warnings for in out parameters
10538 (Analyze_Function_Return): Warn for disallowed null return
10539 Warn on return from procedure with unset out parameter
10540 Ensure consistent use of # in error messages
10541 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10542 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10543 the implicit conversion of the expression done for anonymous access
10544 types. This is required to generate the code of the null excluding
10545 check (if required).
10547 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10548 A formal parameter is never publicly referenceable outside of its body.
10549 (Check_References): For an unreferenced formal parameter in an accept
10550 statement, use the same warning circuitry as for subprogram formal
10552 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10553 Output_Unreferenced_Messages, containing the part of that routine that
10554 is now reused for entry formals as described above.
10555 (Goto_Spec_Entity): New function
10556 (Check_References): Do not give IN OUT warning for dispatching operation
10557 Improve warnings for in out parameters
10558 (Test_Ref): Check that the entity is not undefinite before calling
10559 Scope_Within, in order to avoid infinite loops.

10565 Gary Dismukes <dismukes@adacore.com>
10567 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10568 (Expand_N_Attribute_Reference): Further unify the handling of the
10569 three forms of access attributes, using common code now for all three
10570 cases. Add a test for the case of applying an access attribute to
10571 an explicit dereference when the context is an access-to-interface
10572 type. In that case we need to apply the conversion to the prefix
10573 of the explicit dereference rather than the prefix of the attribute.
10574 (Attribute_Version, UET_Address): Set entity as internal to ensure
10575 proper dg output of implicit importation.
10576 (Expand_Access_To_Type): Removed.
10577 (Expand_N_Attribute_Reference): Merge the code from the three cases
10578 of access attributes, since the processing is largely identical for
10579 these cases. The substantive fix here is to process the case of a
10580 type name prefix (current instance case) before handling the case
10581 of interface prefixes.

10586 Robert Dewar <dewar@adacore.com>
10588 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10589 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10590 type that is an anonymous access to controlled object, establish
10591 an associated finalization chain to avoid corrupting the global
10592 finalization list when a dynamically allocated object designated
10593 by such a component is deallocated.
10594 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10595 functions that need it, even when not marked Requires_Overriding.
10596 (Initialize_Tag): Replace call to has_discriminants by call to
10597 Is_Variable_Size_Record in the circuitry that handles the
10598 initialization of secondary tags.
10599 (Is_Variable_Size_Record): New implementation.
10600 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10601 Suppress_Initialization pragma for a derived type.
10602 (Is_Variable_Size_Record): New subprogram.
10603 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10604 initial version of this routine and also fixes problems causing
10605 incomplete initialization of the table of interfaces.
10606 (Build_Init_Procedure): Improve the generation of code to initialize the
10607 the tag components of secondary dispatch tables.
10608 (Init_Secondary_Tags): New implementation that simplifies the previous
10609 version of this routine.
10610 (Make_DT): Add parameter to indicate when type has been frozen by an
10611 object declaration, for diagnostic purposes.
10612 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10613 diagnose attemps to freeze a subprogram when some untagged type of its
10614 profile is a private type whose full view has not been analyzed yet.
10615 (Freeze_Array_Type): Generate init proc for packed array if either
10616 Initialize or Normalize_Scalars is set.
10617 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10618 constructing the new profile, copy the null_exclusion indicator for each
10619 parameter, to ensure full conformance of the new body with the spec.
10621 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10622 Create wrappers for constructor functions that need it, even when not
10623 marked Requires_Overriding.
10624 (Covers): Handle properly designated types of anonymous access types,
10625 whose non-limited views are themselves incomplete types.
10626 (Add_Entry): Use an entity to store the abstract operation which hides
10628 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10629 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10630 initialization aggregate.
10631 (Function_Interp_May_Be_Hidden): Rename to
10632 Function_Interp_Has_Abstract_Op.
10633 (Has_Compatible_Type): Remove machinery that skips interpretations if
10634 they are labeled as potentially hidden by an abstract operator.
10635 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10636 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10637 (Write_Overloads): Output the abstract operator if present.
10638 (Add_Entry): Before inserting a new entry into the interpretation table
10639 for a node, determine whether the entry will be disabled by an abstract
10641 (Binary_Op_Interp_May_Be_Hidden): New routine.
10642 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10644 (Function_Interp_May_Be_Hidden): New routine.
10645 (Has_Compatible_Type): Do not consider interpretations hidden by
10646 abstract operators when trying to determine whether two types are
10648 (Has_Hidden_Interp): New routine.
10649 (Set_May_Be_Hidden_Interp): New routine.
10650 (Write_Overloads): Write the status of flag May_Be_Hidden.

10655 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10656 types declared in the declarative part of a nested package body or in
10657 the proper body of a stub.
10658 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10659 of the same dispatch table slot to renamed primitives.
10660 (Make_Select_Specific_Data_Table): Handle private types.
10661 (Tagged_Kind): Handle private types.
10662 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10663 output of implicit importation and exportation.
10664 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10665 first formal of the thunk is always associated with the controlling
10666 type. In addition perform the following code cleanup: remove formal
10667 Thunk_Alias which is no longer required, cleanup evaluation of the
10668 the controlling type, and update the documentation.
10669 Replace occurrence of Default_Prim_Op_Count by
10670 Max_Predef_Prims. Addition of compile-time check to verify
10671 that the value of Max_Predef_Prims is correct.
10672 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10673 (Make_DT): Add parameter to indicate when type has been frozen by an
10674 object declaration, for diagnostic purposes.
10675 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10676 construction of statically allocated dispatch tables.
10677 (Make_DT): In case of library-level tagged types export the declaration
10678 of the primary tag. Remove generation of tags (now done by Make_Tags).
10679 Additional modifications to handle non-static generation of dispatch
10680 tables. Take care of building tables for asynchronous interface types
10681 (Make_Tags): New subprogram that generates the entities associated with
10682 the primary and secondary tags of Typ and fills the contents of Access_
10683 Disp_Table. In case of library-level tagged types imports the forward
10684 declaration of the primary tag that will be declared later by Make_DT.
10685 (Expand_Interface_Conversion): In case of access types to interfaces
10686 replace an itype declaration by an explicit type declaration to avoid
10687 problems associated with the scope of such itype in transient blocks.

10690 Ed Schonberg <schonberg@adacore.com>
10691 Javier Miranda <miranda@adacore.com>
10693 * exp_util.ads, exp_util.adb:
10694 This patch replaces a number of occurrences of explicit tests for N_Null
10695 with calls to Known_Null. This improves tracking of null values, since
10696 Known_Null also catches null constants, and variables currently known to
10697 be null, so we get better tracking.
10698 (Ensure_Defined): create an itype reference only in the scope of the
10700 (Side_Effect_Free): A selected component of an access type that
10701 denotes a component with a rep clause must be treated as not
10702 side-effect free, because if it is part of a linked structure its
10703 value may be affected by a renaming.
10704 (Expand_Subtype_From_Expr): For limited objects initialized with build
10705 in place function calls, do nothing; otherwise we prematurely introduce
10706 an N_Reference node in the expression initializing the object, which
10707 breaks the circuitry that detects and adds the additional arguments to
10708 the called function. Bug found working in the new patch for statically
10709 allocated dispatch tables.
10710 (Is_Library_Level_Tagged_Type): New subprogram.
10711 (Remove_Side_Effects): If the expression of an elementary type is an
10712 operator treat as a function call.
10713 (Make_Literal_Range): If the index type of the array is not integer, use
10714 attributes properly to compute the constraint on the resulting aggregate
10717 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10718 class-wide type whose base type is an incomplete private type, leave
10719 class-wide type unfrozen so that freeze nodes can be generated
10720 properly at a later point.
10721 (Freeze_Entity, array case): Handle case of pragma Pack and component
10722 size attributre clause for same array.
10724 2007-08-14 Vincent Celier <celier@adacore.com>

10732 can be used by gprbuild.
10733 (Slash_Id): Change type to be Path_Name_Type
10734 (Slash): Return a Path_Name_Type instead of a File_Name_Type

10746 including gprmake, so that the same sources in the GNAT repository
10747 can be used by gprbuild.
10749 * prj-dect.adb (Prj.Strt.Attribute_Reference): Set correctly the case
10750 insensitive flag for attributes with optional index.
10751 (Prj.Dect.Parse_Attribute_Declaration): For case insensitive associative
10752 array attribute, put the index in lower case.
10753 Update Project Manager to new attribute names for ghprbuild
10754 Allow all valid declarations in configuration project files
10755 Major update of the Project Manager and of the project aware tools,
10756 including gprmake, so that the same sources in the GNAT repository
10757 can be used by gprbuild.
10759 * prj-env.ads, prj-env.adb:
10760 Major update of the Project Manager and of the project aware tools,
10761 including gprmake, so that the same sources in the GNAT repository
10762 can be used by gprbuild.
10763 (Get_Reference): Change type of parameter Path to Path_Name_Type

11243 Fix comments in bindgen regarding consistency checks done in Bcheck:
11244 the checks are made across units within a partition, not across several
11246 Fix generation of C binder file for VxWorks.
11248 * lib.ads, lib.adb (Generic_Separately_Compiled): Rename to

11250 predicate, and update documentation.
11252 * lib-writ.ads, lib-writ.adb (Write_With_Lines): Minor code
11253 reorganization and documentation update for the case of predefined
11254 library generics (for which we do not reference an Afile).

11350 (Set_Item): When the new item is an element of the currently allocated
11351 table passed by reference, save a copy on the stack if we're going
11352 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11353 variable to determine whether to call Set_Last.

11368 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11369 derived type with interface progenitors use the analyzed formal as the
11370 parent of the actual, to create renamings for all the inherited
11371 operations in Derive_Subprograms.
11372 (Collect_Previous_Instances): new procedure within of
11373 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11374 unit being loaded, to ensure that the generation of global symbols is
11375 consistent in different compilation modes.
11376 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11377 takes progenitor types into account.
11378 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11379 traversing over the primitives of the formal and actual types to locate
11380 any abstract subprograms of the actual type that correspond to a
11381 nonabstract subprogram of the formal type's ancestor type(s), and issue
11382 an error if such is found.
11383 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11384 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11385 Remove bogus guard around calls to Inherit_Context.
11386 (Reset_Entity): If the entity is the selector of a selected component
11387 that denotes a named number, propagate constant-folding to the generic
11388 template only if the named number is global to the generic unit.
11389 (Set_Instance_Env): Only reset the compilation switches when compiling
11390 a predefined or internal unit.
11392 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11394 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11395 parameter to determine whether operation applies to the prefix.
11396 (Complete_Object_Operation): If actual has an access type and
11397 controlling formal is not an in_parameter, reject the actual if it is
11398 an access_to_constant type.
11399 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11400 type, the candidate operations are found in the scope of declaration of
11401 the type, because the type has no primitive subprograms.
11402 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11403 a private extension, only examine visible components before trying to
11404 analyze as a prefixed call.
11405 Change Entity_List to Type_To_Use, for better readability.
11406 (Has_Fixed_Op): Use base type when checking whether the type of an
11407 operator has a user-defined multiplication/division
11408 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when

11414 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11415 formal At_Any_Place indicating, when True, that we want to test for
11416 availability of the stream attribute at any place (as opposed to the
11417 current visibility context only).
11418 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11419 purpose of enforcing E.2.2(8) only if it is not available at any place.
11420 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11421 when checking the legality of an extension aggregate in a preelaborable
11422 package. Treat the literal null as a valid default expression in a
11423 component declaration for a type with preelaborable initialization.
11424 A limited interface is a legal progenitor for the designated type of a
11425 remote access to class-wide type.

11434 setting the Referenced_As_LHS flag for entities that are implicitly
11436 (Find_Type): If the type is an internally generated incomplete type,
11437 mark the full view as referenced, to prevent spurious warnings.
11438 (Find_Selected_Component, Has_Components): Handle properly non-limited
11439 views that are themselves incomplete types.
11440 Handle interfaces visible through limited-with clauses.
11441 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11442 subprogram generic actual for which we have generated a renaming.
11443 Warn when the renaming introduces a homonym of
11444 the renamed entity, and the renamed entity is directly visible.

11453 the allocator is not a coextension.
11454 (Resolve): Skip an interpretation hidden by an abstract operator only
11455 when the type of the interpretation matches that of the context.
11456 (Resolve): When looping through all possible interpretations of a node,
11457 do not consider those that are hidden by abstract operators.
11458 (Resolve_Actuals): When verifying that an access to class-wide object
11459 is an actual for a controlling formal, ignore anonymous access to
11460 subprograms whose return type is an access to class_wide type.
11461 (Resolve_Slice): If the prefix of the slice is a selected component
11462 whose type depends on discriminants, build its actual subtype before
11463 applying range checks on the bounds of the slice.
11464 (Valid_Conversion): In an instance or inlined body, compare root types,
11465 to prevent anomalies between private and public views.
11466 (Resolve): Improve error message for ambiguous fixed multiplication
11467 expressions that involve universal_fixed multiplying operations.

11484 typecode parameters for a union (in a variant record), remove
11485 extraneous layer of Any wrapping for member label.
11486 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
11487 elabration statements, register the package with the name server
11488 at the beginning, not at the end, of the elaboration statements so
11489 that they can create remote access to subprogram values that designate
11490 remote subprograms from the package.
11492 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
11494 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
11495 values to compute the number of seconds since the Unix Epoc in order to

11681 rather than a boolean flag, in order to detect circularities in
11684 * par-load.adb: Use current with_clause in calls to Load_Unit, rather
11685 than propagating the From_Limited_With flag, in order to handle
11686 properly circularities involving with_clauses.

11700 Add s-osinte-vxworks-kernel.adb to the target pairs of the
11701 kernel run-time lib for VxWorks 6, which would provide a different
11702 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
11703 x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now

12544 (build_call_alloc_dealloc): When releasing a super-aligned object,
12545 retrieve the system's allocator return value from where build_allocator
12546 has stored it, just ahead of the adjusted address we are passed.

12573 (Gen_Output_File_Ada, Gen_Output_File_C): Never use __attribute
12574 ((destructor)) for adafinal, even when switch -a is used.
12575 Do not issue pragma Linker_Destructor for adafinal when switch -a is
12577 (Gen_Object_Files_Options): Add formatting of Linker Options, when
12578 Output_Linker_Option_List is set. Suppress this formatting when
12579 Zero_Formatting is set.
12580 Add case for CLI_Target.
12581 (System_Restrictions_Used): New flag, used to avoid generating with of
12582 System_Restrictions and initialization of the data unless there is
12583 some use of System.Restrictions in the partition.

12615 Code clean up: remove obsolete code related to GCC 2.
12616 (Get_E_Length): Protect against bomb in case scope is standard
12617 (Selected_Range_Checks): If the node to be checked is a conversion to
12618 an unconstrained array type, and the expression is a slice, use the
12619 bounds of the slice to construct the required constraint checks.
12620 Improve NOT NULL error messages
12621 (Apply_Constraint_Check): If the context is a null-excluding access
12622 type, diagnose properly the literal null.

12638 Arnaud Charlet <charlet@adacore.com>
12640 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12641 applicable to types that have the With_Type flag set. Returns the
12642 non-limited view of the type, if available, otherwise the type itself.
12643 For class-wide types, there is no direct link in the tree, so we have
12644 to retrieve the class-wide type of the non-limited view of the Etype.
12645 New attributes Static_Initialization and Static_Elaboration_Desired.
12646 Remove the pragma Thread_Body, and the associated flag
12647 Is_Thread_Body in entities, and all related code.
12648 (Suppress_Value_Tracking_On_Call): New flag
12649 E_Exception has Esize and Alignment fields

12661 (Root_Type): Handle properly subtypes of class-wide-types.
12664 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12665 class-wide types visible through limited-with clauses.
12666 (Try_Primitive_Operation): When examining all primitive operations of a
12667 tagged type, do not consider subprograms labeled as hidden unless they
12668 belong to a private generic type with a tagged parent.
12669 (Try_Object_Operation): Extensive rewriting, to handle properly various
12670 overloading cases, when several ancestors may have class-wide operations
12671 that are possible candidates, and when the overloaded functions return
12672 array types and have defaulted parameters so that the call may be
12673 interpreted as an indexing.
12674 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12675 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12676 successive actuals before analyzing the call itself.
12677 (Try_Primitive_Operation): A primitive operation is compatible with the
12678 prefix if the prefix has a synchronized type and the type of the formal
12679 is its corresponding record, as can be the case when the primitive
12680 operation is declared outside of the body of the type.
12681 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12682 perform homonym traversal, looking for class-wide operation matches
12683 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12684 access parameters are now restricted to anonymous access types.
12685 (Mark_Allocator): An allocator with a discriminant association parent is
12687 (Try_One_Prefix_Interpretation): If the type of the object is
12688 incomplete, as can be happen when it is a limited view obtained through
12689 a limited_with_clause, the selected component is not part of a prefixed
12691 (Complete_Object_Operation): Diagnose properly an object that is not
12692 aliased when the corresponding controlling formal is an access
12694 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12695 ambiguous calls in prefixed notation, where two primitives differ only
12696 in that the controlling argument of one is an access parameter.
12698 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12699 whether a function that returns an unconstrained type can be inlined.
12700 (Process_Formals): Diagnose properly the illegal use of an incomplete
12701 type in the profile of an access_to_subprogram declaration.
12702 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12703 operations are attached to the corresponding record.
12704 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12705 When processing a primitive of a concurrent type which implements an
12706 interface change the type of all controlling formals to that of the
12707 corresponding record type.
12708 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12709 to determine the tagged type to which a primitive belongs.
12710 (Check_Conventions): Capture condition to ignore a primitive operation
12711 (which is shared between the loop in Check_Conventions and the one in
12712 Check_Convention) in a new local function Skip_Check.
12713 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12714 confusion with Check_Conventions' own Prim_Op local variable.
12715 (Create_Extra_Formals): Test for a tagged result type rather than a
12716 controlling result when determining whether to add a BIP_Alloc_Form
12717 formal and a BIP_Final_List formal to the function.
12718 (Check_Conformance); For parameters that are anonymous access types,
12719 subtype conformance requires that the not null and the constant
12720 indicators must match
12721 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12722 to retrieve the appropriate type when processing a concurrent type
12723 declared within a generic. Minor comment reformatting. Change invocation
12724 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12726 (Analyze_Subprogram_Body): If the return type of a function is an
12727 anonymous access to the limited view of a class-wide type, and the
12728 non-limited view of the type is available, update the type of the
12729 function so that code can be generated.
12730 (Process_Formals): In case of access-subtype itype whose designated
12731 type is also an itype (situation that happens now with access to
12732 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12733 attribute to avoid backend problems.
12734 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12735 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12736 anonymous types' designated types are same before testing
12737 Subtypes_Statically_Match.
12738 (Create_Extra_Formals): Test for a named access parameter that is a
12739 controlling formal as an additional condition for adding an
12740 accessibility level formal. This can occur in the subp type created for
12741 dispatching calls in Expand_Dispatching_Call, and allows calling
12742 Create_Extra_Formals from that procedure rather than special-casing the
12743 extra formals there.
12744 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12745 when the function has a controlling result.
12746 (Check_Returns): Add much more knowledge of the optimization of local
12747 raise statements to gotos, to retain proper warnings in this case.
12748 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12749 nodes when looking for last statement.
12751 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12752 class-wide types visible through limited with clauses.
12753 (Add_One_Interp): If the operands are anonymous access types, the
12754 predefined operator on universal_access is immediately visibles
12755 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12756 other anonymous access types.
12757 (Disambiguate): Take into account CIL convention.
12758 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12760 2007-06-06 Robert Dewar <dewar@adacore.com>

12765 Fix lower bound of tables.
12768 * nlists.adb: Ditto.

12777 * exp_aggr.ads, exp_aggr.adb:
12778 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12779 in extension aggregates.
12780 (Flatten): Other conditions being met, an aggregate is static if the
12781 low bound given by component associations is different from the low
12782 bound of the base index type.
12783 (Packed_Array_Aggregate_Handled): If the component type is itself a
12784 packed array or record, the front-end must expand into assignments.
12785 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12786 Init_Pr, instead of Ancestor_Is_Expression.
12787 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12788 coextension chain root, either generate a list controller or use the
12789 already existing one.
12790 (Static_Array_Aggregate): New procedure to construct a positional
12791 aggregate that can be handled by the backend, when all bounds and
12792 components are compile-time known constants.
12793 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12794 types covering interface types into assignments.
12795 (Replace_Type): move to Build_Record_Aggr_Code.
12796 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12797 interface type, convert to the definite type of the aggregate itself,
12798 so that needed components are visible.
12799 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12800 components and the context is an extended return statement do not
12801 create a transient block for it, to prevent premature finalization
12802 before the return is executed.
12803 (Gen_Assign): Do not generate a call to deep adjust routine if the
12804 component type is itself an array of controlled (sub)-components
12805 initialized with an inner aggregate.
12806 (Component_Check): New name for Static_Check. This name is now more
12807 appropriate, and documentation is added which was missing.
12808 (Component_Check): Add test for bit aligned component value
12809 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12810 Tagged_Comps, name is more appropriate given added function below.
12811 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12815 Robert Dewar <dewar@adacore.com>
12817 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12818 Terminated: Add unchecked type conversion from System.Address to
12819 System.Tasking.Task_Id when calling the predefined primitive
12821 Disable new Ada 05 accessibility check for JVM.NET targets, which
12822 cannot be implemented in a practical way.
12823 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12824 the sources always references the tag of the actual object. Therefore,
12825 if 'Tag is applied in the sources to class-wide interface objects we
12826 generate code that displaces "this" to reference the base of the object.
12827 (Expand_N_Attribute_Reference, case Size): Return specified size if
12828 known to front end.
12829 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12830 has code that displaces the pointer of the object to manage interface
12831 types. However this code must not be executed when the prefix is a
12832 subprogram. This bug caused the wrong expansion of the internally
12833 generated assignment that fills the dispatch table when the primitive
12834 is a function returning a class-wide interface type.
12835 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12836 Set_Attribute_Name for Name_Unaligned_Valid.

12839 Gary Dismukes <dismukes@adacore.com>
12841 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12842 If the initialization is the equivalent aggregate of the initialization
12843 procedure of the type, do not remove it.
12844 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12845 initialized to null from having their expression reset to empty and

12856 references where the prefix must be a simple name.
12858 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12859 Namet. Add new arrays Attribute_Name_Modifies_Prefix and

12867 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12868 constrained subtype for a nominal unconstrained type, use its base type
12869 to check for conformance with the context.
12870 (Resolve_Attribute): Remove test of the access type being associated
12871 with a return statement from condition for performing accessibility
12872 checks on access attributes, since this case is now captured by
12873 Is_Local_Anonymous_Access.
12874 (Analyze_Access_Attribute): Set Address_Taken on entity
12875 (Analyze_Attribute, case Address): Set Address_Taken on entity
12876 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12877 validating an access attribute whose prefix is a current instance.
12878 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12879 applied to dispatching operations, if freezing is required then we set
12880 the attribute Has_Delayed_Freeze in the prefix's entity.
12881 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12882 current scope if access of local subprogram taken
12883 (Analyze_Access_Attribute): Check legality of self-reference even if the
12884 expression comes from source, as when a single component association in
12885 an aggregate has a box association.
12886 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12887 the prefix if it is a protected operation and the attribute is
12888 Unrestricted_Access.
12889 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12890 reference to the base type of the context, to force a constraint check
12891 when the context is an access subtype with an explicit constraint.
12892 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12893 node is rewritten as an interface conversion. leave unanalyzed after
12894 resolution, to ensure that type checking against the context will take

12901 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12902 wrapper when the full view of the controlling type of an inherited
12903 function that dispatches on result implements interfaces.
12904 (Expand_N_Object_Declaration): In cases where the type of the
12905 declaration is anonymous access, create finalization list for it.
12906 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12907 if the object has no explicit initialization, to match description of
12908 functionality of pragam Persistent_BSS.
12909 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12910 new function to build static aggregates, to replace initialization call
12911 when static initialization is desired.

12913 its designated type has controlled anonymous access discriminants.
12914 (Build_Equivalent_Aggregate): New procedure to compute a static
12915 aggregate to be used as default initialization for composite types,
12916 instead of a generating a call to the initialization procedure for the
12918 (Build_Initialization_Call): When available, replace a call to the
12919 initialization procedure with a copy of the equivalent static aggregate
12921 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12922 declarations for objects of a class-wide interface type, rather than
12923 just identifiers, to prevent visibility problems.
12924 (Expand_N_Object_Declaration): When expanding the declaration for an
12925 object of a class-wide interface type, preserve the homonym chain of
12926 the original entity before exchanging it with that of the generated
12927 renaming declaration.
12928 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12929 active, because there is no way to handle the exception.
12930 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12931 to do a minimum decoration of the Access_Disp_Table list.
12932 (Expand_Record_Controller): Avoid the addition of the controller between
12933 the component containing the tag of a secondary dispatch table and its
12934 adjacent component that stores the offset to the base of the object.
12935 This latter component is only generated when the parent type has
12936 discriminants ---documented in Add_Interface_Tag_Components).
12937 (Apply_Array_Size_Check): Removed, no longer needed.
12938 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12939 components, create a Master_Entity for it only if it contains tasks.

12951 Register_Primitive, which provides the same functionality.
12952 (Requires_Init_Proc): Return false in case of interface types.
12953 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12955 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12956 is always associated with a predefined primitive because the internal
12957 entities associated with interface types are not predefined primitives.
12958 Therefore, the call to Is_Internal is replaced by a call to the
12959 function Is_Predefined_Dispatching_Operation.
12960 (Make_Eq_If): When generating the list of comparisons for the
12961 components of a given variant, omit the controller component that is
12962 present if the variant has controlled components.
12964 2007-06-06 Javier Miranda <miranda@adacore.com>
12965 Hristian Kirtchev <kirtchev@adacore.com>
12966 Bob Duff <duff@adacore.com>
12968 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12969 handle the creation of finalization lists and calls for nested
12970 coextensions when the root of the chains is part of a return statement.
12971 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12973 (Expand_Record_Equality): Skip components that are interface types.
12974 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12975 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12976 with Rewrite_Coextension. Change the condition for detecting coextension
12978 (Is_Local_Access_Discriminant): Removed.
12979 (Rewrite_Coextension): New routine which rewrites a static coextension
12980 as a temporary and uses its unrestricted access in the construction of
12982 (Complete_Coextension_Finalization): New routine. Generate finalization
12983 attachment calls to all delayed coextensions.
12984 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12985 the allocator is not a coextension itself and has delayed coextensions.
12986 If the current allocator is controlled, but also a coextension, delay
12987 the generation of the finalization attachment call.
12988 Rename local variable "Node" to "Nod" in order to avoid confusion with
12990 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12991 limited types that are not inherently limited. Such an allocator is
12992 illegal, but is generated by the expander for a return statement, to
12993 copy the result onto the secondary stack. This is the only case where a
12994 limited object can be copied. Generate code to displace the pointer
12995 to the object if the qualified expression is a class-wide interface
12996 object. Such displacement was missing and hence the copy of the object
12998 (Apply_Accessibility_Check): Handle allocated objects initialized in
13000 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13001 and Expand_Allocator_Expression. Allocating class-wide interface objects
13002 this routine displaces the pointer to the allocated object to reference
13003 the component referencing the corresponding secondary dispatch table.
13004 Expand_Allocator_Expression): Add missing support to allocate class-wide
13005 interface objects initialized with a qualified expression.
13006 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13007 function result type, and use the finalization list associated with the
13008 function scope in that case (such an anonymous type should not be
13009 treated like an access parameter's type).
13011 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13012 Gary Dismukes <dismukes@adacore.com>
13013 Javier Miranda <miranda@adacore.com>
13015 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13016 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13017 required exception handler.
13018 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13019 properly the case of a function whose return type is a limited
13020 class-wide interface type. Modify the code of the accessibility
13021 check to handle class-wide interface objects. In this case we need to
13022 displace "this" to reference the primary dispatch table to get access
13023 to the TSD of the object (to evaluate its accessibility level).
13024 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13025 rather than a controlling result as one of the conditions for
13026 generating tests of the implicit BIP_Alloc_Form formal. The
13027 initialization assignment is also handled according to whether the
13028 result is tagged instead of controlling.
13029 In the case where the init assignment is inserted in the "then" part of
13030 the allocation conditional, rewrite the target to be a dereference of
13031 the implicit BIP_Object_Access formal.
13032 If the returned value is unconstrained and created on the secondary
13033 stack, mark the enclosing block and function so that the secondary
13034 stack is not reclaimed on return.
13035 Treat returns from functions with controlling results similarly to
13036 returns from functions with unconstrained result subtypes.
13037 If the object returned is unconstrained, and an allocator must be
13038 created for it, analyze the allocator once the block for the extended
13039 return is installed, to ensure that finalizable components
13040 of the expression use the proper finalization list. Guard the call to
13041 Move_Final_List with a check that there is something to finalize.
13042 (Make_Tag_Ctrl_Assignment): Use "old" handling
13043 of controlled type assignment for virtual machines, since new code uses
13044 unsupported features (such as direct access to bytes in memory).
13046 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13047 Ed Schonberg <schonberg@adacore.com>
13049 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13050 accessibility actual, check for the case of an aliased object that has
13051 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13052 we fall into processing for the attribute rather than the name of the
13054 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13055 formal has its address taken in the body, create a temporary to capture
13056 value. If the return type is a limited interface, do not treat the
13057 return value as Controlled.
13058 (Is_In_Place_Function): If the return type is a limited interface,
13059 treat as returning in place. The actual returned object may not always
13060 be limited, but the caller has to assume that it is returned in place.
13061 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13062 context of an allocator, use the correct finalization chain (that is,
13063 the chain belonging to the access type, rather than the chain belonging
13064 to the current scope).
13065 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13066 result type rather than a controlling result as a precondition for
13067 adding an allocation form actual to a build-in-place call.
13068 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13069 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13070 primitive in the dispatch tables. This work is now done by Make_DT when
13071 the type is frozen.
13072 (Register_Predefined_DT_Entry): Removed.
13073 (Add_Return): If end label is not present, use sloc of last statement
13074 for generated return statement in procedure, for better gdb behavior
13076 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13077 object address nodes to ensure proper processing by routines like
13079 (Expand_Call): Fix generation of validity check for parameter
13080 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13081 the allocation form parameter if the result subtype is constrained,
13082 except when the function has a controlling result.
13083 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13084 rather than Is_Controlled and Has_Controlled_Component, since we want to
13085 include class-wide result types in this treatment. Also test for a
13086 controlling result, since that also requires passing a finalization
13088 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13089 even when the result subtype is constrained, to handle calls involving
13090 controlling results.
13091 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13092 is now called even when the result subtype is constrained, to handle
13093 calls involving controlling results.
13094 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13095 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13096 now performs the test).
13097 (Make_Build_In_Place_Call_In_Object_Declaration):
13098 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13099 constrained, to handle calls involving controlling results.
13100 (Add_Return): Accomodate rewritten pattern from local raise to goto
13101 transformation, so that we still recognize an transfer statement
13102 and do the right thing here in that case.
13103 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13104 and end of subprogram code.
13105 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13106 support for primitives that are functions (without formals) with a
13107 controlling result.
13108 (Inherited_From_Formal): If the actual subtype has not generic parent
13109 type, it is not an actual for a formal derived type, and there is no
13110 operation to inherit from the formal.
13112 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13113 Thomas Quinot <quinot@adacore.com>
13115 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13116 inserted cleanup code appropriately for GDB use.
13117 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13118 exception handler for Deep_Adjust or Deep_Finalize.
13119 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13120 Raise_From_Controlled_Operation is available, use a call to that
13121 subprogram instead of a plain "raise Program_Error" node to raise
13122 Program_Error if an exception is propagated from an Adjust or Finalize
13124 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13125 appears in the optional statement list of a triggering alternative, the
13126 scope actions can be inserted directly there, and not in the list that
13127 includes the asynchronous select itself.
13129 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13130 Robert Dewar <dewar@adacore.com>
13131 Hristian Kirtchev <kirtchev@adacore.com>
13133 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13134 generated exception handler appropriately when debugging generated code.
13135 Deal properly with No_Exception_Propagation restriction mode.
13136 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13137 System.Address to System.Tasking.Task_Id when processing the result of
13138 the predefined primitive _disp_get_task_id.
13139 (Expand_N_Asynchronous_Select): Clarify comment.
13140 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13141 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13142 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13143 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13144 privals and for generated call to Complete_Entry_Body, for better gdb
13146 (Copy_Result_Type): Utility to construct a parameter and result profile
13147 for protected functions whose return type is an anonymous access to
13149 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13151 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13152 point when the local-raise-to-goto transformation has taken place.
13154 2007-06-06 Javier Miranda <miranda@adacore.com>
13155 Nicolas Setton <setton@adacore.com>
13157 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13158 functionality when the backend is generating code.
13159 Otherwise any serious error
13160 reported by the backend calling the frontend routine Error_Msg
13161 changes the Compilation_Mode to Check_Semantics, disables the
13162 functionality of this routine and causes the generation of
13163 spureous additional errors.
13165 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13166 debugging information now generated by the compiler for fat-pointer
13168 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13170 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13172 2007-06-06 Thomas Quinot <quinot@adacore.com>
13174 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13175 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13176 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13177 For a remote call to a function with a classwide return type, apply an
13178 E.4(18) check to the returned value.
13179 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13180 stream attributes of the designated type of an RACW, as they are not
13181 dispatching primitive operations.
13183 2007-06-06 Geert Bosch <bosch@adacore.com>
13185 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13187 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13189 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13190 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13192 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13194 2007-06-06 Javier Miranda <miranda@adacore.com>
13196 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13197 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13199 2007-06-06 Javier Miranda <miranda@adacore.com>
13201 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13202 deallocation of class-wide interface objects.
13203 (Expand_Dispatching_Constructor_Call): Take into account that if the
13204 result of the dispatching constructor is an interface type, the
13205 function returns a class-wide interface type; otherwise the returned
13206 object would be actual. The frontend previously accepted returning
13207 interface types because Expand_Interface_Actuals silently performed
13208 the management of the returned type "as if" it were a class-wide
13210 (Expand_Dispatching_Constructor_Call): Replace call to
13211 Make_DT_Access_Action by direct call to Make_Function_Call.
13213 2007-06-06 Robert Dewar <dewar@adacore.com>
13214 Ed Schonberg <schonberg@adacore.com>
13216 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13217 compute masking constant, since we now set Esize properly to the
13219 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13220 to match the alignment.
13221 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13222 packed arrays of 8 bits or less.
13224 * freeze.adb (Freeze_Entity): When freezing the formals of a
13225 subprogram, freeze the designated type of a parameter of an access type
13226 only if it is an access parameter.
13227 Increase size of C convention enumeration object
13228 (Freeze_Entity, array type case): Make sure Esize value is properly
13229 adjusted for the alignment if it is known.
13230 (Freeze_Entity, array type case): When checking bit packed arrays for
13231 the size being incorrect, check RM_Size, not Esize.
13232 (Freeze_Record_Type): Check for bad discriminated record convention
13233 (In_Exp_Body): Return true if the body is generated for a subprogram
13234 renaming, either an attribute renaming or a renaming as body.
13235 (Check_Itype): If the designated type of an anonymous access component
13236 is a non-protected subprogram type, indicate that it is frozen, to
13237 prevent out-of-scope freeze node at some subsequent call.
13238 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13239 only if the subprogram is neither imported nor exported, as well as the
13240 NCA descriptor class if the subprogram is exported.

13244 Robert Dewar <dewar@adacore.com>
13245 Gary Dismukes <dismukes@adacore.com>
13247 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13248 default initialization on an imported object, when there is no
13249 initialization call generated for it.
13250 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13253 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13254 Static_Elaboration_Desired.
13255 Remove pragma Thread_Body.
13256 Implement a new pragma No_Body
13257 Removes the Explicit_Overriding pragma
13258 Remove Optional_Overriding pragma
13259 (Prag): Deal with Universal_Aliasing.
13260 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13261 Pragma_CIL_Constructor): New names.
13263 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13264 uses the equivalent aggregate of a type must be treated as an implicit
13266 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13267 has none of the other categories.
13268 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13269 to apply Import to an object renaming declaration.
13271 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13272 from a C++ class should be declared as limited and that it will be
13273 considererd limited.
13274 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13275 should be declared as limited and that it will be considererd limited.
13276 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13277 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13278 (Analyze_Pragma): Deal with Universal_Aliasing.
13279 (Sig_Flags): Likewise.
13280 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13281 (Overflow_Checks_Unsuppressed): New flag.
13282 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13283 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13284 case of JVM or .NET targets, and compiling user code.
13285 Add debugging convenience routine rv
13287 2007-06-06 Robert Dewar <dewar@adacore.com>
13289 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13290 are interface type.
13291 (Build_Elementary_Input_Call): For floating-point use right type in the
13292 absence of strange size or stream size clauses.
13293 (Build_Elementary_Write_Call): Same fix
13294 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13295 set to value that does not match base type size.
13297 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13299 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13300 object of a limited type can be initialized with a call to a function
13301 that returns in place. If the limited type has unknown discriminants,
13302 and the underlying type is a constrained composite type, build an actual
13303 subtype from the function call, as is done for private types.
13304 (Side_Effect_Free): An expression that is the renaming of an object or
13305 whose prefix is the renaming of a object, is not side-effect free
13306 because it may be assigned through the renaming and its value must be
13307 captured in a temporary.
13308 (Has_Controlled_Coextensions): New routine.
13309 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13310 as is done for other limited types.
13311 (Non_Limited_Designated_Type): new predicate.
13312 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13314 Remove all handling of with_type clauses.

13318 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13319 checksum if the main source could not be parsed.
13320 (Loat_Unit): When processing a child unit, determine properly whether
13321 the parent unit is a renaming when the parent is itself a child unit.
13322 Remove handling of with_type clauses.
13324 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13356 2007-06-06 Robert Dewar <dewar@adacore.com>
13357 Ed Schonberg <schonberg@adacore.com>
13359 * g-comlin.ads, g-comlin.adb:
13360 Add new warning for renaming of function return objects
13362 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13363 (Tree_Read): Use size of object instead of type'object_size, since the
13364 latter is incorrect for packed array types.
13365 (Tree_Write): Same fix
13367 * opt.ads: Add new warning for renaming of function return objects
13368 (Generating_Code): New boolean variable used to indicate that the
13369 frontend as finished its work and has called the backend to process
13370 the tree and generate the object file.

13372 (Static_Dispatch_Tables): New constant declaration.
13373 (Overflow_Checks_Unsuppressed): New flag.

13378 (Warn_On_Unrepped_Components): New flag.
13380 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
13381 unit is a compilation unit, rather than relying on its scope, so that
13382 Standard can be renamed.
13383 (Analyze_Object_Renaming): Add new warning for renaming of function
13385 Also reject attempt to rename function return object in Ada 83 mode.
13386 (Attribute_Renaming): In case of tagged types, add the body of the
13387 generated function to the freezing actions of the type.
13388 (Find_Type): A protected type is visible right after the reserved word
13389 "is" is encountered in its type declaration. Set the entity and type
13390 rather than emitting an error message.
13391 (New_Scope): Properly propagate Discard_Names to inner scopes
13392 (Check_Nested_Access): New procedure.
13393 (Has_Nested_Access, Set_Has_Nested_Access): New procedures.

13830 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
13831 associated with dispatch tables is known at compile time.
13832 (Get_Value): If an association in a record aggregate has a box
13833 association, and the corresponding record component has a default
13834 expression, always copy the default expression, even when the

14935 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
14937 (Resolve_Actuals): If an actual is an allocator for an access parameter,
14938 the master of the created object is the innermost enclosing statement.

15103 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15104 "abstract subprograms must be visible" message, whether or not the type

15132 Remove no longer used entities.
15134 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

15174 "X'Unrestricted_Access = Y'Access" and so forth to match.

15182 attempt to derive from a synchronized tagged type.
15183 (Analyze_Type_Declaration): If there is a incomplete tagged view of the

15187 that use (a subtype of) the class-wide type of the enclosing type.
15188 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15189 Derived_Type for Prev formal on call to
15190 Check_Anonymous_Access_Components rather than Empty.
15191 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15192 a record extension in deciding whether to create a class-wide type,

15195 to stand-alone object declarations as well as component declarations.
15196 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15197 prevent accidental overwriting when enclosing package appears in
15198 a limited_with_clause.
15199 (Array_Type_Declaration): If the component type is an anonymous access,
15200 the associated_node for the itype is the type declaration itself.

15202 types with abstract interfaces.
15203 (Check_Abstract_Interfaces): New subprogram that verifies the ARM
15204 rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).

15209 with abstract interfaces.
15210 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15211 mark, rather than delaying the full resolution depending on context.

15237 Do not collect arguments if project is externally built.
15238 (Compile_Sources): Do nothing, not even check if the source is up to
15239 date, if its project is externally built.
15240 (Compile): When compiling a predefined source, add -gnatpg
15241 as the second switch, after -c.
15242 (Compile_Sources): Allow compilation of Annex J renames without -a
15243 (Is_In_Object_Directory): Check if the ALI file is in the object
15244 even if there is no project extension.
15245 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15246 gnatbind if the ALI file effectively exists.
15247 (Initialize): Add the directory where gnatmake is invoked in front of
15248 the path if it is invoked from a bin directory, even without directory

15273 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15274 when -gnatg is not specified.

15276 there is no need to generate always a record_definition_node in case
15277 of synchronized interface types.

15301 is non-static even if the component is given by an aggregate with
15303 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
15304 (Convert_Aggr_In_Allocator): If the allocator is for an access
15305 discriminant and the type is controlled. do not place on a finalization
15306 list at this point. The proper list will be determined from the

15309 initialize record controller if needed, before the components, to ensure
15310 that they are properly finalized.

15325 succeed in that case, even when the expression originates from a
15326 parameter of the containing subprogram.
15327 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15328 under No_Dispatching_Calls restriction. During the semantic analysis
15329 we already notified such violation.
15330 (Tagged_Membership): Constant folding. There is no need to check
15331 the tag at run-time if the type of the right operand is non
15332 class-wide abstract.

15347 initialize most the TSD components by means of an aggregate.
15348 Modify the declaration of the object containing the TSD
15349 because we now expand code that has a higher level of abstraction.
15350 The TSD has a discriminant containing the Inheritance Depth Level,
15351 value that is used in the membership test but also to fix the size
15352 of the table of ancestors.
15353 (Expand_Interface_Conversion): Insert function body at the closest place
15354 to the conversion expression, to prevent access-before-elaboration
15355 errors in the backend.

15357 compiling under restriction No_Dispatching_Calls plus code cleanup.
15358 Code reorganization plus removal of calls to Set_Num_Prim_Ops

15381 (Expand_Dispatching_Call): Replace generation of call to the run-time
15382 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15383 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15385 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15386 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15391 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15394 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15395 First (Parameter_Associations ()) with the call to First_Actual that
15396 returns an actual parameter expression for both named and positional

15400 check violation of restriction No_Dispatching_Calls.
15401 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15408 specify Any_Limited_Interface, and this functionality is already
15409 provided by the function Has_Abstract_Interfaces.
15410 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15411 support concurrent types implementing interfaces.
15412 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15413 specify kind Any_Limited_Interface, and this functionality is already
15414 provided by the function Has_Abstract_Interfaces.

15416 CW_Or_Controlled_Type whenever the issue is related to
15417 using or not the secondary stack.

15433 anonymous, use finalization list of enclosing dynamic scope.
15434 (Expand_N_Package_Declaration): For a library package declaration
15435 without a corresponding body, generate RACW subprogram bodies in the
15436 spec (just as we do for the task activation call).
15437 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15438 Is_Abstract_Type. Make sure these are called only when appropriate.
15439 Remove all code for DSP option

15456 Family_Size with 'Cap' set to true.
15457 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15458 a protected version of an operation declared in the private part of
15459 a protected object, because they may be invoked through a callback.
15460 (Set_Privals): If the type of a private component is an anonymous access
15461 type, do not create a new itype for each protected body.
15462 If the body of a protected operation creates
15463 controlled types (including allocators for class-widetypes), the
15464 body of the corresponding protected subprogram must include a

15471 for a possible overriding candidate.
15472 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15473 hold an actual parameter value since its initialization is separated

15478 Pablo Oliveira <oliveira@adacore.com>
15480 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15481 Do an Unchecked_Conversion to handle the passage from the Underlying

15483 Build_From_Any_Call.
15484 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15485 E_Constant, depending upon Variable formal.
15486 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,

15491 the unit being compiled is the one that contains the stub type.
15492 Change primitive operation name for the RACW associated with a RAS
15493 from Call to _Call so it cannot clash with any legal identifier.
15494 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15496 (Append_RACW_Bodies): New subprogram.
15497 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15498 Add_Receiving_Stubs_To_Declarations functions.
15499 When expanding a package body, this list correspond to the

15504 registering the receiving stubs at the end of the 'Stmts' list.
15505 (RCI_Package_Locator): Pass the new Version generic formal when
15506 instantiating a RCI_Locator package.
15507 (Build_From_Any_Function): To compute the High bound for an
15508 unconstrained array actual, we add the Low bound with the length.
15509 Thus we must convert the low bound and the length to an appropriate
15510 type before doing the sum.
15511 (Build_Subprogram_Receiving_Stubs, PolyORB):
15512 * Retrieve the extra formals parameters at the
15513 end of the parameter stream.
15514 * Use Move_Any_Value to write back out parameters
15515 after executing the request as it is more efficient
15516 than Copy_Any_Value.
15517 * Build the any containing Extra Formals with the
15518 appropriate typecode.
15519 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15520 empty Component_List.

15533 function with the first not implicit parent type.
15534 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15535 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15536 typecode from the Etype. Therefore we retrieve the correct typecode
15537 with a call to Get_Any_Type.
15538 (Copy_Specification): Do controlling formal type substitution based on
15539 Is_Controlling_Formal flag, instead of caller-provided object type.
15540 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15541 a RACW primitive operation, we might get a subprogram declaration for an
15542 ancestor of the RACW designated type (not for the designated type
15543 itself), in the case where this operation is inherited. In this case we
15544 have no easy means of determining the original tagged type for which
15545 the primitive was declared, so instead we now rely on
15546 Copy_Specification to use the Is_Controlling_Formal flag to determine
15547 which formals require type substitution.

15555 handler unsuitable as a target for a local raise statement.
15556 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15557 run-time subprogram CW_Membership by call to Build_CW_Membership.
15558 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15559 by a function call, a temporary must be created before expanding the
15560 Constructor_Call itself, to prevent out-of-order elaboration in the
15561 back-end when stack checking is enabled..
15563 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15565 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the

15636 (Packages_To_Check_By_Stack): Add this list that contains the packages
15637 to be checked by gnatstack, which are the naming and the stack packages.
15638 (Check_Files): If no .ci files were specified for gnatstack we add all
15639 the .ci files belonging to the projects, including binder generated
15641 (Non_VMS_Usage): Document that gnatstack accept project file switches.
15642 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
15643 Add gnatstack to the list of commands that use project file related
15644 switches, and get the single attribute Switches from the stack package
15645 in a project file when calling gnatstack. Parse the -U flag for
15646 processing files belonging to all projects in the project tree.

15690 standard 8bits encoding.
15691 (WS2SU): As above but converting from wide-sring to string.
15692 This is needed as it is necessary to have access to both versions in the
15693 runtime for the form parameter encoding support.
15694 This set of patch add support for the encoding form parameter.
15695 (S2WS): Improve implementation to handle cases where the filename is not
15696 UTF-8 encoded. In this case we default to using the current code page
15697 for the conversion.
15699 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15700 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15709 corresponding encoding value into AFCB structure.
15710 (Reset): Pass the encoding value to freopen.
15711 (Close): Move the call to Lock_Task to the beginning of the procedure.

15744 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15745 __gnat_adjust_context_for_raise.
15746 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15747 implementation of floating point operations as native x86 targets.
15748 So the FPU should be initialized in the same way using finit. Fix
15749 floating point operations accuracy issues.
15750 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15751 member in struct sigaction, so as to avoid warning for incompatible

15767 Javier Miranda <miranda@adacore.com>
15769 * lib-xref.ads, lib-xref.adb:
15770 Modify the loop that collects type references, to include interface
15771 types that the type implements. List each of these interfaces when
15772 building the entry for the type.
15773 (Generate_Definition): Initialize component Def and Typ of new entry
15774 in table Xrefs, to avoid to have these components unitialized.
15775 (Output_References): Split Is_Abstract flag into
15776 Is_Abstract_Subprogram and Is_Abstract_Type.
15777 (Generate_Reference): Add barrier to do not generate the warning
15778 associated with Ada 2005 entities with entities generated by the

15820 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
15821 it no longer destroys the contents of Name_Buffer or Name_Len and
15822 non-standard and invalid names are handled better.
15823 (Get_Decoded_Name_String): Improve performance by using
15824 Name_Has_No_Encodings flag in the name table.
15825 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
15826 Used for debugging printouts.

15829 Javier Miranda <miranda@adacore.com>
15830 Bob Duff <duff@adacore.com>
15832 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15833 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15834 there is no need to generate always a record_definition_node in case
15835 of synchronized interface types.
15836 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15837 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15838 illegal in Ada 95, in cases where it is legal. Change the warnings to
15839 errors in other cases. Don't give the error unless the "not null"
15840 parses properly. Correct the source position at which the error occurs.
15841 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15842 P_Null_Exclusion, to suppress "not null" warnings.

15894 Entry for pragma Unreferenced_Objects
15896 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
15897 switches, without repetition of "eD". Make sure that last character of
15898 -gnatep= switch is not taken as -gnat switch character.
15899 Complete rewrite of circuit for handling saving compilation options

15928 (Record_Other_Sources): Idem.
15929 (Locate_Directory): Add the possibility to create automatically missing
15930 directories when Setup_Projects is True.

15933 library source copy dir and exec dir.
15935 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15938 2007-04-06 Robert Dewar <dewar@adacore.com>

15972 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
15973 full word is no longer compared twice.
15975 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15977 * sem_ch10.adb (Install_Limited_Context_Clauses.
15978 Expand_Limited_With_Clause): Use a new copy of selector name in the
15979 call to Make_With_Clause. This fixes the tree structure for ASIS
15980 purposes. Nothing is changed in the compiler behaviour.
15981 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15982 a package renaming.
15983 (Install_Limited_With_Clauses): Do not install non-limited view when it
15984 is still incomplete.
15986 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15987 Gary Dismukes <dismukes@adacore.com>
15989 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15990 when capturing size information, instead of base type, which for a
15991 formal array type will be the unconstrained type.
15992 (Analyze_Formal_Object_Declaration): Add check for illegal default
15993 expressions for a formal in object of a limited type.
15994 (Instantiate_Object): Ditto.
15995 (Check_Formal_Package_Instance): Skip entities that are formal objects,
15996 because they were defaulted in the formal package and no check applies
15998 (Check_Formal_Package_Instance): Extend conformance check to other
15999 discrete types beyond Integer.
16000 (Process_Default): Copy directly the unmatched formal. A generic copy
16001 has already been performed in Analyze_Formal_Package.
16002 (Analyze_Associations): If a formal subprogram has no match, check for
16003 partial parametrization before looking for a default, to prevent
16005 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16006 not set the instantiation environment before analyzing the actuals.
16007 Fixes regression on 8515-003 with implementation of AI-133.
16008 Set_Instance_Env checks whether the generic unit is a predefined
16009 unit, in which case the instance must be analyzed with the latest Ada
16010 mode. This setting must take place after analysis of the actuals,
16011 because the actuals must be analyzed and frozen in the Ada mode extant
16012 outside of the current instantiation.
16013 (Save_Env, Restore_Env): Preserve and restore the configuration
16014 parameters so that predefined units can be compiled in the proper Ada
16016 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16017 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16018 and Is_Abstract_Type.
16019 (Analyze_Formal_Package): For better error recovery, Add exception
16020 handler to catch Instantion_Error, which can be raised in
16021 Analyze_Associations
16023 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16024 Bob Duff <duff@adacore.com>
16025 Gary Dismukes <dismukes@adacore.com>
16027 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16028 prefix type is a discriminated subtype of the type of the formal.
16029 (Analyze_Allocator): Collect all coextensions regardless of the context.
16030 Whether they can be allocated statically is determined in exp_ch4.
16031 (Analyze_Selected_Component): If the prefix is a limited view and the
16032 non-limited view is available, use the non-limited one.
16033 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16034 therefore illegal), suggest a qualified expression rather than a type
16035 conversion, because a type conversion would be illegal in this context.
16036 (Anayze_Allocator): Trace recursively all nested allocators so that all
16037 coextensions are on the corresponding list for the root. Do no mark
16038 coextensions if the root allocator is within a declaration for a stack-
16039 allocated object, because the access discriminants will be allocated on
16041 (Analyze_Call): Remove restriction on calls to limited functions for the
16042 cases of generic actuals for formal objects, defaults for formal objects
16043 and defaults for record components.
16044 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16045 element list. Their expansion is delayed until the enclosing allocator
16046 is processed and its finalization list constructed.
16047 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16048 for an operation with the given name among the primitive operations of
16049 the corresponding record type.
16050 (Analyze_Selected_Component): If the prefix is a task type that
16051 implements an interface, and there is no entry with the given name,
16052 check whether there is another primitive operation (e.g. a function)
16054 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16055 properly the indexing of a function call written in prefix form, where
16056 the function returns an array type, and all parameters of the function
16057 except the first have defaults.
16058 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16059 the original operands, rather than relocating them, for efficiency and
16060 to work properly when an operand is overloaded.
16061 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16062 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16063 (Analyze_Selected_Component): If the prefix is a private extension, only
16064 scan the visible components, not those of the full view.
16065 (Try_Primitive_Operation): If the operation is a procedure, collect all
16066 possible interpretations, as for a function, because in the presence of
16067 classwide parameters several primitive operations of the type can match
16068 the given arguments.
16070 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16071 Robert Dewar <dewar@adacore.com>
16073 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

16079 Thomas Quinot <quinot@adacore.com>
16081 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16082 out of Analyze_Package_Declaration, because processing must be applied
16083 to package bodies as well, for deferred constants completed by pragmas.
16084 (Analyze_Package_Declaration): When the package declaration being
16085 analyzed does not require an explicit body, call Check_Completion.
16086 (May_Need_Implicit_Body): An implicit body is required when a package
16087 spec contains the declaration of a remote access-to-classwide type.
16088 (Analyze_Package_Body): If the package contains RACWs, append the
16089 pending subprogram bodies generated by exp_dist at the end of the body.
16090 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16091 Is_Abstract_Subprogram and Is_Abstract_Type.
16092 (Preserve_Full_Attributes): The full entity list is not an attribute
16093 that must be preserved from full to partial view.

16136 rather than local Same_Formal_Type, to check whether protected operation
16137 overrides an inherited one.
16138 (Same_Formal_Type): New predicate, used when matching signatures of
16139 overriding synchronized operations, to handle the case when a formal
16140 has a type that is a generic actual.

16158 same result than Is_Ancestor.
16159 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16160 (Collect_Synchronized_Interfaces): Removed because the subprogram
16161 Collect_Abstract_Interfaces provides this functionality.

16207 high bound is constant and the slice is empty. Tidy.
16208 (tree_transform, case N_Op_Not): Handle properly the case where the
16209 operation applies to a private type whose full view is a modular type.
16210 (Case_Statement_To_gnu): If an alternative is an E_Constant with an

16212 representing the choice value to ensure the corresponding GCC tree is
16213 of the proper kind.
16214 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16215 instead of just the operands, as the base GCC stabilize_reference does.
16216 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16217 requested; otherwise fail.
16218 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16478 (mainly static expression evaluation).
16479 Reword some continuation messages
16480 Add some \\ sequences to continuation messages

16497 Valid_Conversion, to incorporate accessibility checks for arrays of
16498 anonymous access types.
16499 (Valid_Conversion): For a conversion to a numeric type occurring in an
16500 instance or inlined body, no need to check that the operand type is
16501 numeric, since this has been checked during analysis of the template.

16533 (Leap_Sec_Ops): New package in the private part of Ada.Calendar. This
16534 unit provides handling of leap seconds and is used by the new Ada 2005
16535 packages Ada.Calendar.Arithmetic and Ada.Calendar.Formatting.

17016 sem_util and renamed as Collect_All_Abstract_Interfaces.
17017 (Set_All_DT_Position): Hidden entities associated with abstract
17018 interface primitives are not taken into account in the check for

17030 alias of a predefined dispatching primitive.
17031 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17032 compiling under full ABI compatibility mode we avoid the generation of
17033 calls to run-time services that fill the dispatch tables because under
17034 this mode we currently inherit the dispatch tables in the IP subprogram.
17035 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17036 (Expand_Interface_Conversion): Use an address as the type of the formal
17037 of the internally built function that handles the case in which the

17088 we request a discriminal value only in case of discriminants.
17089 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17090 assignments where the target subtype is unconstrained and the target
17091 object is a parameter or dereference (other aliased cases are known

17207 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17208 are build-in-place function calls.
17209 (Replace_Self_Reference): New subsidiary of
17210 Make_OK_Assignment_Statement, to replace an access attribute that is a
17211 self-reference into an access to the appropriate component of the
17212 target object. Generalizes previous mechanism to handle self-references
17213 nested at any level.
17214 (Is_Self_Referential_Init): Remove, not needed.

17219 (Has_Default_Init_Comps): Return True if a component association is a
17220 self-reference to the enclosing type, which can only come from a
17221 default initialization.
17222 (Make_OK_Assignment_Statement): If the expression is of the form
17223 Typ'Acc, where Acc is an access attribute, the expression comes from a
17224 default initialized self-referential component.
17225 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17226 that has been derived from several abstract interfaces we must also

17232 Robert Dewar <dewar@adacore.com>
17235 (Expand_Access_To_Protected_Op): If the context indicates that an access
17236 to a local operation may be transfered outside of the object, create an
17237 access to the wrapper operation that must be used in an external call.
17238 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17239 target, pass the Valid attribute applied to a floating-point prefix on
17240 to the back end without expansion.

17242 the allocated storage when it is specified by a per-object expression.

17255 subcomponent's enclosing variable is aliased with a constrained subtype.
17256 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17257 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17258 an aliased prefix must be known to be constrained in order to use True
17259 for the attribute value, and now it's possible for some aliased views
17260 to be unconstrained.
17262 2006-10-31 Robert Dewar <dewar@adacore.com>
17264 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue

17275 otherwise we incorrectly register the tag of the interface in the final
17277 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17278 generate the wrapper if the parent primitive is abstract. This is
17279 required to report the correct error message.
17280 (Expand_N_Subtype_Indication): Do validity checks on range
17281 (Clean_Task_Names): If an initialization procedure includes a call to

17285 compatibility for interfacing with CPP by default.
17286 (Expand_N_Object_Declaration): Only build an Adjust call when the

17288 * exp_ch3.adb: Add with and use of Exp_Ch6.
17289 (Expand_N_Object_Declaration): Check for object initialization that is a
17290 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17291 Object_Declaration to the call.
17292 (Freeze_Type): When the designated type of an RACW was not frozen at the
17293 point where the RACW was declared, validate the primitive operations
17294 with respect to E.2.2(14) when it finally is frozen.
17295 (Build_Initialization_Call,Expand_Record_Controller): Rename
17296 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17297 return-by-reference has no meaning in Ada 2005.
17298 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17299 to register tag of the immediate ancestor interfaces in the
17300 run-time structure.

17302 initialization of extension aggregates with abstract interfaces.
17303 (Build_Master_Renaming): Make public, for use by function declarations
17304 whose return type is an anonymous access type.
17305 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17306 Insert_List_Before_And_Analyze after the generation of the specs
17307 associated with null procedures.

17309 (Init_Secondary_Tags): Update documentation.
17310 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17311 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17312 then generate code to inherit the contents of the dispatch table
17313 directly from the ancestor.
17314 (Expand_Record_Controller): Insert controller component after tags of
17315 implemented interfaces.
17316 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17317 create null procedure overridings when null procedures are inherited

17320 declarations for overriding null primitives inherited from interfaces.
17321 (Is_Null_Interface_Procedure): New function in
17322 Make_Null_Procedure_Specs.
17323 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17324 immediate ancestor of a tagged type is an abstract interface type we
17325 must generate the specification of the predefined primitives associated
17326 with controlled types (because the dispatch table of the ancestor is
17327 null and hence these entries cannot be inherited). This is required to
17328 elaborate well the dispatch table.

17342 the maximum for type T.
17343 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17344 when the allocator is initialized by a build-in-place call, since the
17345 allocator is already rewritten as a reference to the function result,
17346 and this prevents an unwanted duplication of the function call.
17347 Add with and use of Exp_Ch6.
17348 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17349 is a call to build-in-place function and apply
17350 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17351 untagged designated types).
17352 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17353 optimization if source or target is biased.
17354 (Expand_N_Allocator): Add comments for case of an allocator within a

17367 (Expand_N_Assignment_Statement): Call
17368 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a

17370 assignments that come from aggregates.
17371 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17372 in order to alleviate the upward compatibility introduced by AI-318.
17373 (Expand_N_Extended_Return_Statement): Add support for handling the
17374 return object as a build-in-place result.
17375 (Expand_Non_Function_Return): Implement simple return statements nested
17376 within an extended return.
17377 (Enable_New_Return_Processing): Turn on the new processing of return
17379 (Expand_Non_Function_Return): For a return within an extended return,
17380 don't raise Program_Error, because Sem_Ch6 now gives a warning.

17387 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17388 validity checking of assignments to elementary record components.
17389 (Expand_N_Return_Statement): return Class Wide types on the secondary
17390 stack independantly of their controlled status since with HIE runtimes,
17391 class wide types are not potentially controlled anymore.
17393 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17396 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17397 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17398 it expects a block, procedure, or task. The return statement will get
17399 turned into a block, and Expand_Cleanup_Actions will happen then.

17406 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17408 (Expand_Inlined_Call): Tagged types are by-reference types, and
17409 therefore should be replaced by a renaming declaration in the expanded
17410 body, as is done for limited types.
17411 (Expand_Call): If this is a call to a function with dispatching access
17412 result, propagate tag from context.
17413 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17415 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17416 build-in-place when the right-hand side of an assignment is a
17417 build-in-place function call.
17418 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17419 of the explicit dereference of the allocator to the result subtype of
17420 the build-in-place function. This is needed to satisfy type checking
17421 in cases where the caller's return object is created by an allocator for
17422 a class-wide access type and the type named in the allocator is a
17424 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17425 conversion of the reference to the declared object to the result subtype
17426 of the build-in-place function. This is needed to satisfy type checking
17427 in cases where the declared object has a class-wide type. Also, in the
17428 class-wide case, change the type of the object entity to the specific
17429 result subtype of the function, to avoid passing a class-wide object
17430 without explicit initialization to the back end.
17431 (Register_Interface_DT_Entry): Moved outside the body of
17432 Freeze_Subprogram because this routine is now public; it is called from
17433 Check_Dispatching_Overriding to handle late overriding of abstract
17434 interface primitives.
17435 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17436 adding an implicit access actual on a call to a build-in-place function.
17437 (Expand_Actuals): Test for an actual parameter that is a call to a
17438 build-in-place function and apply
17439 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17440 (Is_Build_In_Place_Function): New function to determine whether an
17441 entity is a function whose calls should be handled as build-in-place.
17442 (Is_Build_In_Place_Function_Call): New function to determine whether an
17443 expression is a function call that should handled as build-in-place.
17444 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17445 calls to build-in-place functions as the initialization of an allocator.
17446 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17447 handling calls to build-in-place functions in contexts that do not
17448 involve init of a separate object (for example, actuals of subprogram
17450 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17451 handling calls to build-in-place functions as the initialization of an
17452 object declaration.
17453 (Detect_Infinite_Recursion): Add explicit parameter Process to
17454 instantiation of Traverse_Body to avoid unreferenced warning.
17455 (Check_Overriding_Inherited_Interfaces): Removed.
17456 (Register_Interface_DT_Entry): Code cleanup.
17457 (Register_Predefined_DT_Entry): Code cleanup.
17458 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17459 inlined statements if within a transient scope.
17460 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17461 formal parameters with occurrences of actuals in inlined body, establish
17462 visibility on the proper view of the actual's subtype for the body's
17464 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17465 compatibility mode and we have an imported CPP subprogram because
17466 for now we assume that imported CPP primitives correspond with
17467 objects whose constructor is in the CPP side (and therefore we
17468 don't need to generate code to register them in the dispatch table).
17469 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17470 aligned selected component.
17471 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17472 the actual of an in-mode parameter is a type conversion.
17473 (Expand_Actuals): If the call does not come from source and the actual
17474 is potentially misaligned, let gigi handle it rather than rejecting the
17475 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17476 Class Wide types as returning by reference independantly of their
17477 controlled status since with HIE runtimes class wide types are not
17478 potentially controlled anymore.
17480 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17482 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17483 references that are private components of the protected object.

17494 initialization of Homonym_Len.
17495 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17496 names from fully qualified name. Fixes problem of duplicate
17497 external names differing only in the presence of such a block name.

17500 Pablo Oliveira <oliveira@adacore.com>
17502 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17503 subprogram Ids, even if they are not yet assigned.
17504 (Build_Subprogram_Id): It is now this function that will take care of
17505 calling Assign_Subprogram_Ids if necessary.
17506 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17507 should be done only once they are assigned.
17508 (Build_From_Any_Function, case of tagged types): Add missing call to
17510 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17511 type for an RACW type.
17512 (Add_RACW_Features): When processing an RACW declaration for which the
17513 designated type is already frozen, enforce E.2.2(14) rules immediately.
17514 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17515 special reordering of controlling formals.
17517 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17518 associated stub type for an RACW type.
17520 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17522 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17523 fixed-point operations in an integer context, i.e. as operands of a
17524 conversion to an integer type, indicate that result must be rounded.
17526 2006-10-31 Robert Dewar <dewar@adacore.com>
17528 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17529 cases, pass the encoding method, since it is now required by the run
17532 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17533 assumption that Str'First = 1.
17534 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17535 it on to the Value_Wide_Wide_Character call.
17536 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17537 properly handles a string of the form quote-encoded_wide_char-quote.
17539 * s-wchcnv.adb: Minor reformatting
17541 2006-10-31 Javier Miranda <miranda@adacore.com>
17543 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17544 run-time membership test to ensure that the constructed object
17545 implements the target abstract interface.
17547 2006-10-31 Robert Dewar <dewar@adacore.com>
17549 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17550 Machine_Attribute pragma internally to implement the user pragma.
17551 Add processing for pragma Interface so that it is now completely
17552 equivalent to pragma Import.
17554 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17555 so that it can be applied to all entities, including record components
17556 and enumeration literals.
17557 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17558 priority ranges are correct, verify compatibility against task
17559 dispatching and locking policies, and if everything is correct an entry
17560 is added to the table containing priority specific dispatching entries
17561 for this compilation unit.
17562 (Delay_Config_Pragma_Analyze): Delay processing
17563 Priority_Specific_Dispatching pragmas because when processing the
17564 pragma we need to access run-time data, such as the range of
17565 System.Any_Priority.
17566 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17567 Allow pragma Unreferenced as a context item
17568 Add pragma Preelaborable_Initialization
17569 (Analyze_Pragma, case Interface): Interface is extended so that it is
17570 now syntactically and semantically equivalent to Import.
17571 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17572 insertion characters.
17573 Add handling for Pragma_Wide_Character_Encoding
17574 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17575 never supercedes a real restriction, and that a real restriction
17576 always supercedes a warning.
17577 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17584 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17585 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17586 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17588 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17589 type of the function containing a return statement, because the
17590 Return_Type field was removed. We now use the Return_Applies_To field.
17592 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17593 (Build_Task_Image_Decl): If procedure is not called from an
17594 initialization procedure, indicate that function that builds task name
17595 uses the sec. stack. Otherwise the enclosing initialization procedure
17596 will carry the indication.
17597 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17598 N_Object_Declaration instead.
17599 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17600 conditional dead code killed, and change implementation accordingly.
17601 (Insert_Actions): Add N_Return_Object_Declaration case.
17602 Correct comment to mention N_Extension_Aggregate node.
17603 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17604 attempts to save information for global variables which cannot be
17606 (Get_Current_Value_Condition): Handle conditions the other way round
17607 (constant on left). Also handle right operand of AND and AND THEN
17608 (Set_Current_Value_Condition): Corresponding changes
17609 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17610 (Get_Current_Value_Condition): Handle simple boolean operands
17611 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17612 (Get_Current_Value_Condition): If the variable reference is within an
17613 if-statement, does not appear in the list of then_statments, and does
17614 not come from source, treat it as being at unknown location.
17615 (Get_Current_Value_Condition): Enhance to allow while statements to be
17616 processed as well as if statements.
17617 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17619 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17620 of loop. This is safe now that we fixed Kill_Current_Values.
17621 (OK_To_Do_Constant_Replacement): Check whether current scope is
17622 Standard, before examining outer scopes.
17624 2006-10-31 Vincent Celier <celier@adacore.com>

17639 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17641 * g-expect.adb: Add Warnings (Off) to prevent new warning
17643 * lib-xref.adb: Add handling of Last_Assignment field
17644 (Generate_Reference): Centralize handling of pragma Obsolescent here
17645 (Generate_Reference): Accept an implicit reference generated for a
17646 default in an instance.
17647 (Generate_Reference): Accept a reference for a node that is not in the
17648 main unit, if it is the generic body corresponding to an subprogram
17651 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17653 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17655 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17657 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17658 use clauses, to avoid messages on packages used to qualify, and also
17659 to avoid messages from obsolescent units.
17660 (Warn_On_Useless_Assignments): Don't generate messages for imported
17661 and exported variables.
17662 (Warn_On_Useless_Assignments): New procedure

17668 (Last_Assignment): New field for useless assignment warning
17670 2006-10-31 Olivier Hainque <hainque@adacore.com>
17672 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17673 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.

17676 Robert Dewar <dewar@adacore.com>
17677 Ed Schonberg <schonberg@adacore.com>
17679 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17680 Ada 95 mode, because it violates the new rules for AI-318.
17682 * g-awk.ads: Use overloaded subprograms in every case where we used to
17683 have a default of Current_Session. This makes the code closer to be
17684 correct for both Ada 95 and 2005.
17686 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17687 code, relying on the fact that the compiler generates a warning
17688 instead of an error in -gnatg mode.
17690 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17691 E_Return_Statement entity kind.
17692 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17694 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17695 report an error if the reserved word abstract has been previously found.
17696 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17698 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17699 parenthesized range attribute usage
17700 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17702 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17703 in the syntax for extended_return_statement. This is not in the latest
17704 RM, but the ARG is expected to issue an AI allowing this.
17705 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17706 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17707 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17708 P_Return_Statement): Parse the new syntax for extended_return_statement.
17710 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17711 Output_End_Missing): Add error-recovery code for the new
17712 extended_return_statement syntax; that is, the new E_Return entry on
17715 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17716 limited to nonlimited, because otherwise we violate the new Ada 2005
17717 rules about returning limited types in function Create_AST_Handler in
17720 * sem.adb (Analyze): Add cases for new node kinds
17721 N_Extended_Return_Statement and N_Return_Object_Declaration.
17723 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17724 type is in the same category as type of context before applying check,
17725 to prevent anomalies in instantiations.
17726 (Resolve_Aggregate): Remove test for limited components in aggregates.
17727 It's unnecessary in Ada 95, because if it has limited components, then
17728 it must be limited. It's wrong in Ada 2005, because limited aggregates
17730 (Resolve_Record_Aggregate): Move check for limited types later, because
17731 OK_For_Limited_Init requires its argument to have been resolved.
17732 (Get_Value): When copying the component default expression for a
17733 defaulted association in an aggregate, use the sloc of the aggregate
17734 and not that of the original expression, to prevent spurious
17735 elaboration errors, when the expression includes function calls.
17736 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17737 were missing. We also didn't handle qualified expressions. Now also
17738 allow function calls. Use new common routine OK_For_Limited_Init.
17739 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17740 with space can upper case letter).
17742 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17743 Has_Static_Discriminants flag
17744 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17745 type with discriminants.
17746 (Process_Range_Expr_In_Decl): Do validity checks on range
17747 (Build_Discriminant_Constraints): Use updated form of
17748 Denotes_Discriminant.
17749 (Process_Subtype): If the subtype is a private subtype whose full view
17750 is a concurrent subtype, introduce an itype reference to prevent scope
17752 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17753 Record_Type_Declaration): The functionality of the subprograms
17754 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17755 is now performed by a single routine.
17756 (Build_Derived_Record_Type): If the type definition includes an explicit
17757 indication of limitedness, then the type must be marked as limited here
17758 to ensure that any access discriminants will not be treated as having
17759 a local anonymous access type.
17760 (Check_Abstract_Overriding): Issue a detailed error message when an
17761 abstract subprogram was not overridden due to incorrect mode of its
17763 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17764 synchronized private extension declarations. Verify that the ancestor is
17765 a limited or synchronized interface or in the generic case, the ancestor
17766 is a tagged limited type or synchronized interface and all progenitors
17767 are either limited or synchronized interfaces.
17768 Derived_Type_Declaration): Check for presence of private extension when
17769 dealing with synchronized formal derived types.
17770 Process_Full_View): Enchance the check done on the usage of "limited" by
17771 testing whether the private view is synchronized.
17772 Verify that a synchronized private view is completed by a protected or
17774 (OK_For_Limited_Init_In_05): New function.
17775 (Analyze_Object_Declaration): Move check for limited types later,
17776 because OK_For_Limited_Init requires its argument to have been resolved.
17777 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17778 in order to alleviate the upward compatibility introduced by AI-318.
17779 (Constrain_Corresponding_Record): If the constraint is for a component
17780 subtype, mark the itype as frozen, to avoid out-of-scope references to
17781 discriminants in the back-end.
17782 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17783 this subprogram against wrong sources.
17784 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17785 discriminant of limited type completed with a protected type, when the
17786 discriminant is used to constrain a private component of the type, and
17787 expansion is disabled.
17788 (Find_Type_Of_Object): Do not treat a return subtype that is an
17789 anonymous subtype as a local_anonymous_type, because its accessibility
17790 level is the return type of the enclosing function.
17791 (Check_Initialization): In -gnatg mode, turn the error "cannot
17792 initialize entities of limited type" into a warning.
17793 (OK_For_Limited_Init): Return true for generated nodes, since it
17794 sometimes violates the legality rules.
17795 (Make_Incomplete_Declaration): If the type for which an incomplete
17796 declaration is created happens to be the currently visible entity,
17797 preserve the homonym chain when removing it from visibility.
17798 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17799 inherited subprograms.
17800 (Access_Definition): If this is an access to function that is the return
17801 type of an access_to_function definition, context is a type declaration
17802 and the scope of the anonymous type is the current one.
17803 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17804 incomplete subtype to the set of private dependents of the original
17806 (Constrain_Discriminated_Type): Emit an error message whenever an
17807 incomplete subtype is being constrained.
17808 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17809 corresponding subtype of the full view of the original incomplete type.
17810 (Check_Incomplete): Properly detect invalid usage of incomplete types
17813 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17815 * g-catiio.ads, g-catiio.adb (Value): New function.

17824 Robert Dewar <dewar@adacore.com>
17826 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17827 handling executable extension manually and duplicating code.
17829 * make.adb: Implement new -S switch
17830 (Gnatmake): Use new function Osint.Executable_Name instead
17831 of handling executable extension manually.
17833 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17834 is specified, the executable name ends with this suffix.
17835 Take advantage of Osint.Executable_Name instead of duplicating code.
17837 * switch-m.adb: Recognize new gnatmake -S switch
17839 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17841 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17844 * makeusg.adb: Add line for gnatmake -S switch
17846 2006-10-31 Vincent Celier <celier@adacore.com>
17848 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17849 call it with -static-libgcc, as there are some platforms, such as
17850 Darwin, where one of these two switches is compulsory to link.
17852 2006-10-31 Vincent Celier <celier@adacore.com>
17854 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17855 instead of ADA_PROJECT_PATH, for the project path.
17856 (Gnatls): When displaying the project path directories, use host dir
17859 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17860 names in the project path, as absolute paths may correspond to
17861 multi-valued VMS logical names.
17863 2006-10-31 Vincent Celier <celier@adacore.com>
17865 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17866 absolute path name.
17867 (Locate_Regular_File): Ditto
17868 (Change_Dir): Remove, no longer used
17869 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17870 on Windows. Get it calling Get_Current_Dir.
17871 (OpenVMS): Remove imported boolean, no longer needed.
17872 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17873 (Pid_To_Integer): New function to convert a Process_Id to Integer
17875 2006-10-31 Thomas Quinot <quinot@adacore.com>

17878 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17880 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17883 2006-10-31 Robert Dewar <dewar@adacore.com>
17885 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
17886 initial letter o as a zero.
17888 2006-10-31 Robert Dewar <dewar@adacore.com>
17890 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
17892 2006-10-31 Robert Dewar <dewar@adacore.com>
17894 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17896 (Layout_Variant_Record): Retrieve the discriminants from the entity
17897 rather than from the type definition, because in the case of a full
17898 type for a private type we need to take the discriminants from the
17900 (Layout_Component_List): When applying the Max operator to variants with
17901 a nonstatic size, check whether either operand is static and scale that
17902 operand from bits to storage units before applying Max.
17903 (Layout_Type): In VMS, if a C-convention access type has no explicit
17904 size clause (and does not inherit one in the case of a derived type),
17905 then the size is reset to 32 from 64.
17907 2006-10-31 Vincent Celier <celier@adacore.com>
17909 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17910 its file has already been loaded, according to the unit being loaded,
17911 not to the current value of Multiple_Unit_Index.
17913 2006-10-31 Thomas Quinot <quinot@adacore.com>
17914 Eric Botcazou <ebotcazou@adacore.com>
17915 Arnaud Charlet <charlet@adacore.com>
17917 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
17918 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
17920 (a-except.o): Pass it to the compiler.
17921 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
17922 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
17923 a-calend-mingw.adb version.

17926 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
17927 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
17928 Ada.Dispatching.Round_Robin.
17929 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
17931 * Make-lang.in: Remove all references to gt-ada-decl.h.
17932 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
17934 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
17935 Update dependencies.
17937 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
17939 2006-10-31 Vincent Celier <celier@adacore.com>
17941 * mlib-utl.adb (Initialized): Remove, no longer used
17942 (Initialize): Remove, no longer used
17943 (Ar): If Ar_Exec is null, get the location of the archive builder and,
17944 if there is one, the archive indexer. Fail if the archive builder cannot
17946 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
17949 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17951 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17952 Process_Body_Clauses): If the context of a body includes a use clause
17953 for P.Q then a with_clause for P in the same body is not redundant,
17954 even if the spec also has a with_clause on P.
17955 Add missing continuation mark to error msg
17956 (Build_Limited_Views): A limited view of a type is tagged if its
17957 declaration includes a record extension.
17958 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17959 node, even if the subunit has errors. This avoids malfunction by
17960 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17961 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17962 generation of obsolescent messages for with statements (cannot do
17963 this too early, or we cannot implement avoiding the messages in the
17964 case of obsolescent units withing obsolescent units).
17965 (Install_Siblings): If the with_clause is on a remote descendant of
17966 an ancestor of the current compilation unit, find whether there is
17967 a sibling child unit that is immediately visible.
17968 (Remove_Private_With_Clauses): New procedure, invoked after completing
17969 the analysis of the private part of a nested package, to remove from
17970 visibility the private with_clauses of the enclosing package
17972 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17973 now centralized in Generate_Reference.
17974 (Install_Limited_Context_Clauses): Remove superfluous error
17975 message associated with unlimited view visible through use
17976 and renamings. In addition, at the point in which the error
17977 is reported, we add the backslash to the text of the error
17978 to ensure that it is reported as a single error message.
17979 Use new // insertion for some continuation messages
17980 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17981 to create implicit with_clause for parent unit mentioned in original
17982 limited_with_clause.
17983 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17984 unit is a child unit. For ASIS queries.
17985 (Analyze_Subunit): If the subunit appears within a child unit, make all
17986 ancestor child units directly visible again.
17988 2006-10-31 Robert Dewar <dewar@adacore.com>

17998 Add the new actual Abstract_Present to every call to
17999 P_Interface_Type_Definition.
18000 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18001 a formal object declaration with an access definition or a subtype mark
18002 with a null exclusion.
18003 (P_Generic_Association): Handle association with box, and others_choice
18004 with box, to support Ada 2005 partially parametrized formal packages.
18006 2006-10-31 Robert Dewar <dewar@adacore.com>
18007 Javier Miranda <miranda@adacore.com>
18009 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18010 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18011 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18012 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18013 private extensions.
18014 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18015 to P_Interface_Type_Definition.
18016 (P_Interface_Type_Definition): Addition of one formal to report an error
18017 if the reserved word abstract has been previously found.
18018 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18019 object renaming declaration with an access definition or subtype mark
18020 with a possible null exclusion.
18022 * par-ch9.adb: Minor error msg fix
18024 * par-load.adb: Add missing continuation mark to error msg
18026 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation

18030 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
18031 unknown attribute in unknown package or in package that does not need
18033 (Parse_Package_Declaration): Do not issue warning for unknown package in
18036 2006-10-31 Vincent Celier <celier@adacore.com>
18038 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
18039 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18042 2006-10-31 Vincent Celier <celier@adacore.com>
18044 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18045 on VMS, change "__" to '.' before checking the name.
18046 (Record_Ada_Source): Always add the source file name in the list of
18047 of sources, even if it is not the first time, as it is for another
18049 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18050 dot, instead of replacing only the first '_'.
18052 * prj-part.adb (Parse): Convert project file path to canonical form
18054 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18055 extended, the project id of the project extending it is recorded in its
18056 data, even when it has already been processed as an imported project.
18058 2006-10-31 Robert Dewar <dewar@adacore.com>
18060 * repinfo.adb (List_Entities): Don't list entities from renaming
18063 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18064 Robert Dewar <dewar@adacore.com>
18066 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18067 only a restriction warning is active for the given restriction. This is
18068 desirable because we do not want to modify code in the case where only
18070 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18071 causes overriding of real restrictions.
18072 Take advantage of new No_Restrictions constant.
18074 * raise.h: (__gnat_set_globals): Change profile.
18076 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18078 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18081 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18082 Move all the entities in obsolete package System.PolyORB_Interface to
18083 System.Partition_Interface.
18084 (RE_Storage_Size): New function in System.Tasking.
18085 (RE_Get_Ceiling): New entity.
18086 (RE_Set_Ceiling): New entity.
18087 (RO_PE_Get_Ceiling): New entity.

18097 Thomas Quinot <quinot@adacore.com>
18098 Javier Miranda <miranda@adacore.com>
18099 Gary Dismukes <dismukes@adacore.com>
18101 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18102 properly an attempt to apply Unchecked_Access to a protected operation.
18103 (OK_Self_Reference): New subprogram to check the legality of an access
18104 attribute whose prefix is the type of an enclosing aggregate.
18105 Generalizes previous mechanism to handle attribute references nested
18106 arbitrarily deep within the aggregate.
18107 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18108 can appear in an aggregate if this is a default-initialized aggregate
18109 for a self-referential type.
18110 (Resolve_Attribute, case Access): Ditto.
18111 Add support for new implementation defined attribute Stub_Type.
18112 (Eval_Attribute, case Attribute_Stub_Type): New case.
18113 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18114 (Stream_Attribute_Available): Implement using new subprogram from
18115 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18116 Has_Specified_Stream_Attribute flag.
18117 Disallow Storage_Size and Storage_Pool for access to subprogram
18118 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18119 access types of return subtypes in extended return statements. Remove
18120 accessibility checks on anonymous access types when Unchecked_Access is
18122 (Analyze_Attribute): Add support for the use of 'Class to convert
18123 a class-wide interface to a tagged type.
18124 Add support for the attribute Priority.
18125 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18126 whether the designated type is discriminated with a constrained partial
18127 view and require static matching in that case.
18128 Add local variable Des_Btyp. The Designated_Type
18129 of an access to incomplete subtype is either its non-limited view if
18130 coming from a limited with or its etype if regular incomplete subtype.
18132 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18133 Fix predicate to identify and allow cases of (expander-generated)
18134 references to tag of designated object of a RACW.
18135 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18136 non-static, and therefore cannot appear as a primary in a preelaborable
18138 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18139 Has_Read_Write_Attributes.
18140 (Has_Read_Write_Attributes): Reimplement in termes of
18141 Has_Stream_Attribute_Definition.
18142 (Missing_Read_Write_Attributes): When checking component types in a
18143 record, unconditionally call Missing_Read_Write_Attributes recursively
18144 (remove guard checking for Is_Record_Type / Is_Access_Type).
18146 2006-10-31 Robert Dewar <dewar@adacore.com>
18148 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18149 useless assignments here and conditionalize it on absence of exception
18151 (Analyze_Exception_Handlers): Small code reorganization of error
18152 detection code, for new handling of formal packages.
18154 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18155 Hristian Kirtchev <kirtchev@adacore.com>
18157 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18158 that has been constant-folded, preserve information of original tree,
18160 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18161 generated private extension declaration if the formal derived type is
18162 synchronized. Carry synchronized present over to the generated private
18164 (Validate_Derived_Type_Instance): Ensure that the actual of a
18165 synchronized formal derived type is a synchronized tagged type.
18166 (Instantiate_Formal_Package): When creating the instantiation used to
18167 validate the actual package of a formal declared without a box, check
18168 whether the formal itself depends on a prior actual.
18169 (Instantiate_Formal_Subprogram): Create new entities for the defining
18170 identifiers of the formals in the renaming declaration, for ASIS use.
18171 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18172 a renaming declaration or a subtype declaration for an actual in an
18173 instance, capture location information of declaration in generic, for
18175 (Instantiate_Formal_Package): Add comments on needed additional tests.
18176 AI-317 (partial parametrization) is fully implemented.
18177 (Validate_Private_Type_Instance): Add check for actual which
18178 must have preelaborable initialization
18179 Use new // insertion for some continuation messages
18180 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18181 Default_Expression. Add type retrieval when the declaration has an
18182 access definition. Update premature usage of incomplete type check.
18183 (Check_Access_Definition): New subsidiary routine. Check whether the
18184 current compilation version is Ada 05 and the supplied node has an
18186 (Instantiate object): Alphabetize local variables. Handle the creation
18187 of new renaming declarations with respect to the kind of definition
18188 used - either an access definition or a subtype mark. Guard against
18189 unnecessary error message in the context of anonymous access types after
18190 they have been resolved. Add check for required null exclusion in a
18191 formal object declaration.
18192 (Switch_View): A private subtype of a non-private type needs to be
18193 switched (the base type can have been switched without its private
18194 dependents because of the last branch of Check_Private_View.
18195 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18197 (Instantiate_Type): Emit an error message whenever a class-wide type of
18198 a tagged incomplete type is used as a generic actual.
18199 (Find_Actual_Type): Extend routine to handle a component type in a child
18200 unit that is imported from a formal package in a parent.
18201 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18202 agree on constrainedness, rather than checking against ultimate ancestor
18203 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18204 generic body, for navigation purposes.
18206 2006-10-31 Robert Dewar <dewar@adacore.com>
18207 Thomas Quinot <quinot@adacore.com>
18209 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18211 (New_Stream_Subprogram): When processing an attribute definition clause
18212 for a stream-oriented subprogram, record an entity node occurring at
18213 the point of clause to use for checking the visibility of the clause,
18214 as defined by 8.3(23) as amended by AI-195.
18215 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18216 New_Stream_Function and New_Stream_Procedure.
18217 (New_Stream_Function, New_Stream_Procedure): Removed.
18218 (Analyze_Attribute_Definition_Clause, case Address): Check new
18219 Alignment_Check check
18221 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18222 Javier Miranda <miranda@adacore.com>
18223 Robert Dewar <dewar@adacore.com>
18225 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18226 generate the same errors compiling under -gnatc.
18227 (Try_Object_Operation): If no candidate interpretation succeeds, but
18228 there is at least one primitive operation with the right name, report
18229 error in call rather than on a malformed selected component.
18230 (Analyze_Selected_Component): If the prefix is an incomplete type from
18231 a limited view, and the full view is available, use the full view to
18232 determine whether this is a prefixed call to a primitive operation.
18233 (Operator_Check): Verify that a candidate interpretation is a binary
18234 operation before checking the type of its second formal.
18235 (Analyze_Call): Add additional warnings for function call contexts not
18237 (Analyze_Allocator): Move the check for "initialization not allowed for
18238 limited types" after analyzing the expression. This is necessary,
18239 because OK_For_Limited_Init looks at the structure of the expression.
18240 Before analysis, we don't necessarily know what sort of expression it
18241 is. For example, we don't know whether F(X) is a function call or an
18242 indexed component; the former is legal in Ada 2005; the latter is not.
18243 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18244 were missing. We also didn't handle qualified expressions. Now also
18245 allow function calls. Use new common routine OK_For_Limited_Init.
18246 (Analyze_Type_Conversion): Do not perform some legality checks in an
18247 instance, because the error message will be redundant or spurious.
18248 (Analyze_Overloaded_Selected_Component): Do not do style check when
18249 setting an entity, since we do not know it is the right entity yet.
18250 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18251 (Analyze_Overloaded_Selected_Component): Same change
18252 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18253 since regular incomplete subtypes are transformed into corresponding
18254 subtypes of their full views.
18255 (Complete_Object_Operation): Treat name of transformed subprogram call
18256 as coming from source, for browsing purposes.
18257 (Try_Primitive_Operation): If formal is an access parameter, compare
18258 with base type of object to determine whether it is a primitive
18260 (Operator_Check): If no interpretation of the operator matches, check
18261 whether a use clause on any candidate might make the operation legal.
18262 (Try_Class_Wide_Operation): Check whether the first parameter is an
18263 access type whose designated type is class-wide.
18265 2006-10-31 Robert Dewar <dewar@adacore.com>
18266 Ed Schonberg <schonberg@adacore.com>
18267 Gary Dismukes <dismukes@adacore.com>
18269 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18270 warn on infinite loops.
18271 Add \\ to some continuation messages
18272 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18273 (Process_Bounds): If the bounds are integer literals that result from
18274 constant-folding, and they carry a user-defined type, preserve that type
18275 rather than treating this as an integer range.
18276 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18277 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18278 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18279 left hand side of assignment.
18280 (Analyze_Assignment): Add suport to manage assigments to the attribute
18281 priority of a protected object.
18282 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18283 not just identifiers.
18284 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18285 or AND THEN for possible tracking.
18286 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18287 case of while loops so we can track values in the loop body.
18289 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18290 Hristian Kirtchev <kirtchev@adacore.com>
18291 Bob Duff <duff@adacore.com>
18293 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18294 procedure cannot be a protected operation (it is a basic_declaration,
18295 not a subprogram_declaration).
18296 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18297 Subp. Add logic for entry processing.
18298 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18299 Determine whether an entry or subprogram of a protected or task type
18300 override an inherited primitive of an implemented interface.
18301 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18302 Update the actual used in calls to Check_Overriding_Indicator.
18303 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18304 generate the proper reference to the parent unit, for cross-reference.
18305 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18307 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18308 (Add_Extra_Formal): Revise procedure to allow passing in associated
18309 entity, scope, and name suffix, and handle setting of the new
18310 Extra_Formals field.
18311 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18312 pass new parameters. Add support for adding the new extra access formal
18313 for functions whose calls are treated as build-in-place.
18314 (Analyze_A_Return_Statement): Correct casing in error message.
18315 Move Pop_Scope to after Analyze_Function_Return, because an extended
18316 return statement really is a full-fledged scope. Otherwise, visibility
18317 doesn't work right. Correct use of "\" for continuation messages.
18318 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18319 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18320 the node doesn't get properly marked as analyzed.
18321 (Analyze_Subprogram_Body): If subprogram is a function that returns
18322 an anonymous access type that denotes a task, build a Master Entity
18324 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18325 proper usage of null exclusion in a result definition.

18354 we are in its visible part.
18355 (Declare_Inherited_Private_Subprograms): Complete barrier
18356 to ensure that the primitive operation has an alias to some parent
18357 primitive. This is now required because, after the changes done for the

18360 such list of primitives.
18361 (Analyze_Package_Specification): Simplify code that handles parent units
18362 of instances and formal packages.

18378 as potentially use-visible.
18379 (Find_Type): Handle the case of an attribute reference for
18380 implementation defined attribute Stub_Type (simply let the analysis of

18407 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18408 Check_Overriding_Indicator.
18409 (Analyze_Task_Definition): Ditto.
18410 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18411 (Check_Overriding_Indicator): To find overridden interface operation,
18412 examine only homonyms that have an explicit subprogram declaration, not
18413 inherited operations created by an unrelated type derivation.
18414 (Check_Overriding_Indicator): When checking for the presence of "null"
18415 in a procedure, ensure that the queried node is a procedure

18433 of a call to a function that dispatches on access result.
18434 (Check_Dispatching_Operation): In case of late overriding of a primitive
18435 that covers abstract interface subprograms we register it in all the
18436 secondary dispatch tables associated with abstract interfaces.
18437 (Check_Dispatching_Call): Add check that a dispatching call is not made
18438 to a function with a controlling result of a limited type. This is a
18439 current implementation restriction.
18440 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).

18487 (Unqualify): New function for removing zero or more levels of
18488 qualification from an expression. There are numerous places where this
18489 ought to be used, but we currently only deal properly with zero or one
18491 (In_Instance); The analysis of the actuals in the instantiation of a
18492 child unit is not within an instantiation, even though the parent
18493 instance is on the scope stack.

18496 (Check_Obsolescent): Removed
18497 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18752 This is a significant redesign primarily for the sake of automatic
18753 timer task termination but also to fix a design flaw.
18754 Therefore we are now using an RTS lock, instead of a protected
18755 object, to provide mutual exclusion to the queue of pending events
18756 and the type Timing_Event is no longer a protected type.

19604 other basic tools. The full version that includes the Ada 2005 stuff
19605 is in separate files a-except-2005.ads/adb. The reason is that we do
19606 not want to cause bootstrap problems with compilers not recognizing

19928 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
19929 Remove 0-9 as debug flag character possibilities
19930 -d is now controlling the primary stack size when its value is a
19931 positive. Also add checks against invalid values, and support for kb,
19932 mb. Ditto for -D switch.
19934 2006-02-13 Robert Dewar <dewar@adacore.com>
19935 Serguei Rybin <rybin@adacore.com>
19937 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19938 save/restore routines.
19939 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

19941 Since we are changing the tree format anyway, also get rid of the
19942 junk obsolete Immediate_Errors flag.
19943 (Tree_Read): Change the way of reading Tree_Version_String - now we
19944 read the version string from the tree even if its length is not the
19945 same as the length of the version string computed from Gnatvsn.
19946 (Search_Directory_Present): New Boolean flag for the compiler.
19947 Define Tree_Version_String as a dynamic string.

19962 Ed Schonberg <schonberg@adacore.com>
19964 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend

19968 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
19969 (Is_Known_Null): New flag
19970 (Has_Pragma_Pure): New flag
19971 (No_Return): Present in all entities, set only for procedures
19972 (Is_Limited_Type): A type whose ancestor is an interface is limited if
19973 explicitly declared limited.
19974 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
19975 entities. Only used for component marked Is_Tag. If present it stores
19976 the Offset_To_Top function used to provide this value in tagged types
19977 whose ancestor has discriminants.
19979 * exp_ch2.adb: Update status of new Is_Known_Null flag
19981 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
19983 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in

20000 (__gl_default_stack_size): new variable.
20002 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20004 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20005 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20006 does not exist in the Ada RM.
20007 (Compatible_Int_Bounds): Determine whether two integer range bounds
20008 are of equal length and have the same start and end values.
20009 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20010 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20011 aggregate when it is part of an object declaration.
20012 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20013 constrains discriminants of its parent, add explicitly the discriminant
20014 constraints of the ancestor by retrieving them from the
20015 stored_constraint of the parent.
20017 2006-02-13 Robert Dewar <dewar@adacore.com>
20019 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20020 attribute Mechanism_Code is applied to renamed subprogram, modify
20021 prefix to point to base subprogram.
20022 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20024 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20025 renamed subprograms so that the front-end must replace the prefix
20028 2006-02-13 Javier Miranda <miranda@adacore.com>
20029 Gary Dismukes <dismukes@adacore.com>
20031 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20032 availability of RE_Interface_Tag.
20033 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20034 (Freeze_Record_Type): Do not generate the tables associated with
20035 timed and conditional dispatching calls through synchronized
20036 interfaces if compiling under No_Dispatching_Calls restriction.
20037 When compiling for Ada 2005, for a nonabstract
20038 type with a null extension, call Make_Controlling_Function_Wrappers
20039 and insert the wrapper function declarations and bodies (the latter
20040 being appended as freeze actions).
20041 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20042 predefined primitives associated with timed and conditional
20043 dispatching calls through synchronized interfaces if we are
20044 compiling under No_Dispatching_Calls.
20045 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20046 service is available before generating a call.
20047 (Make_Controlling_Function_Wrappers): New procedure.
20048 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20049 access-to-limited-interfaces because they can be used to reference
20050 tasks that implement such limited interface.
20051 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20052 procedure spec and body of the Offset_To_Top function that is generated
20053 when the parent of a type with discriminants has secondary dispatch
20055 (Init_Secondary_Tags): Handle the case in which the parent of the type
20056 containing secondary dispatch tables has discriminants to generate the
20057 correct arguments to call Set_Offset_To_Top.
20058 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20060 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20061 Add Wide_[Wide_]Expanded_Name.
20062 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20063 the same functionality of Get_Prim_Op_Address but applied to predefined
20064 primitive operations because the pointers to the predefined primitives
20065 are now saved in a separate table.
20066 (Parent_Size): Modified to get access to the separate table of primitive
20067 operations or the parent type.
20068 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20069 functionality of Set_Prim_Op_Address but applied to predefined primitive
20071 (Set_Signature): New subprogram used to store the signature of a DT.
20072 (Displace): If the Offset_To_Top value is not static then call the
20073 function generated by the expander to get such value; otherwise use
20074 the value stored in the table of interfaces.
20075 (Offset_To_Top): The type of the actual has been changed to Address to
20076 give the correct support to tagged types with discriminants. In this
20077 case this value is stored just immediately after the tag field.
20078 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20079 offset_to_top value is static and hence pass this value to the run-time
20080 to store it in the table of interfaces, or else if this value is dynamic
20081 and then pass to the run-time the address of a function that is
20082 generated by the expander to provide this value for each object of the
20085 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20086 (Default_Prim_Op_Count): New entity
20087 (Get_Predefined_Prim_Op_Address): New entity

20091 2006-02-13 Thomas Quinot <quinot@adacore.com>
20092 Ed Schonberg <schonberg@adacore.com>
20094 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20095 Make_Adjust_Call done for a newly-allocated object.
20097 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20098 in a subprogram are wrapped in a cleanup block, indicate that the
20099 subprogram contains an inner block with an exception handler.
20100 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20101 Adjust call is for a newly-allocated object. In that case we must not
20102 assume that the finalization list chain pointers are correct (since they
20103 come from a bit-for-bit copy of the original object's pointers) so if
20104 the attach level would otherwise be zero (no change), we set it to 4
20105 instead to cause the pointers to be reset to null.
20107 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20108 reset chain pointers to null.
20110 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20112 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20113 string, and the context requires a loop for the assignment (e.g.
20114 because the left-hand side is packed), generate a unique name for the
20115 temporary that holds the string, to prevent spurious name clashes.
20117 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20118 Javier Miranda <miranda@adacore.com>
20119 Robert Dewar <dewar@adacore.com>
20120 Gary Dismukes <dismukes@adacore.com>
20122 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20123 return unconstrained arrays.
20125 (Expand_Call): An indirect call through an access parameter of a
20126 protected operation is not a protected call.
20127 Add circuit to raise CE in Ada 2005 mode following call
20128 to Raise_Exception.
20129 (Register_DT_Entry): Do nothing if
20130 the run-time does not give support to abstract interfaces.
20131 (Freeze_Subprogram): In case of dispatching operations, do not generate
20132 code to register the operation in the dispatch table if the source
20133 is compiled with No_Dispatching_Calls.
20134 (Register_Predefined_DT_Entry): Generate code that calls the new
20135 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20136 Set_Prim_Op_Address.
20138 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20139 on array assignments if the right-hand side is a function call that has
20140 been inlined. Check is performed on the assignment in the block.
20141 (Process_Bounds): If bounds and range are overloaded, apply preference
20142 rule for root operations to disambiguate, and diagnose true ambiguity.
20143 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20144 a tag-indeterminate right-hand side even when Expander_Active is True.
20145 Needed to ensure that dispatching calls to T'Input are allowed and
20146 get the tag of the target class-wide object.
20148 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20149 an inherited primitive operation that already overrides several
20150 abstract interface primitives. For transitivity, the new entity must
20151 also override all the abstract interface primitives covered by the
20152 inherited overriden primitive.
20153 Emit warning if new entity differs from homograph in same scope only in
20154 that one has an access parameter and the other one has a parameter of
20155 a general access type with the same designated type, at the same
20156 position in the signature.
20157 (Make_Inequality_Operator): Use source locations of parameters and
20158 subtype marks from corresponding equality operator when creating the
20159 tree structure for the implicit declaration of "/=". This does not
20160 change anything in behaviour except that the decoration of the
20161 components of the subtree created for "/=" allows ASIS to get the
20162 string images of the corresponding identifiers.
20163 (Analyze_Return_Statement): Remove '!' in warning message.
20164 (Check_Statement_Sequence): Likewise.
20165 (Analyze_Subprogram_Body): For an access parameter whose designated type
20166 is an incomplete type imported through a limited_with clause, use the
20167 type of the corresponding formal in the body.
20168 (Check_Returns): Implicit return in No_Return procedure now raises
20169 Program_Error with a compile time warning, instead of beging illegal.
20170 (Has_Single_Return): Function returning unconstrained type cannot be
20171 inlined if expression in unique return statement is not an identifier.
20172 (Build_Body_To_Inline): It is possible to inline a function call that
20173 returns an unconstrained type if all return statements in the function
20174 return the same local variable. Subsidiary procedure Has_Single_Return
20175 verifies that the body conforms to this restriction.
20177 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20178 same type, and one of them is of an anonymous access type, convert
20179 the other operand to it, so that this is a valid binary operation for
20181 (Resolve_Type_Conversion): Handle subtypes of protected types and
20182 task types when accessing to the corresponding record type.
20183 (Resolve_Allocator): Add '\' in 2-line warning message.
20184 Remove '!' in warning message.
20185 (Resolve_Call): Add '\' in 2-line warning message.
20186 (Valid_Conversion): Likewise.
20187 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20188 resulting type may be an access type with an implicit dereference.
20189 Obtain the proper component from the designated type.
20190 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20191 given by an expanded name with prefix Standard, when the operands are
20192 of an anonymous access type.
20193 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20194 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20195 prefix of the expression is not of an incomplete type. Allows full
20196 diagnoses of all semantic errors.
20197 (Resolve_Actuals): If the actual is an allocator whose directly
20198 designated type is a class-wide interface we build an anonymous
20199 access type to use it as the type of the allocator. Later, when
20200 the subprogram call is expanded, if the interface has a secondary
20201 dispatch table the expander will add a type conversion to force
20202 the displacement of the pointer.
20203 (Resolve_Call): If a function that returns an unconstrained type is
20204 marked Inlined_Always and inlined, the call will be inlined and does
20205 not require the creation of a transient scope.
20206 (Check_Direct_Boolean_Op): Removed
20207 (Resolve_Comparison_Op): Remove call to above
20208 (Resolve_Equality_Op): Remove call to above
20209 (Resolve_Logical_Op): Inline above, since this is only call.
20210 (Valid_Conversion): Handle properly conversions between arrays of
20211 convertible anonymous access types.
20214 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20215 the literal in an unchecked conversion, because GCC 4.x needs a static
20216 value for a string bound.
20218 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20219 Hristian Kirtchev <kirtchev@adacore.com>
20221 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20222 components of the corresponding record, take into account component
20223 definitions that are access definitions.
20224 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20225 procedure is not considered a dispatching call and will be expanded
20228 2006-02-13 Javier Miranda <miranda@adacore.com>
20230 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20231 controlling argument of the dispatching call is an abstract interface
20232 class-wide type then we use it directly.
20233 Check No_Dispatching_Calls restriction.
20234 (Default_Prim_Op_Position): Remove the code that looks for the last
20235 entity in the list of aliased subprograms. This code was wrong in
20237 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20238 when the source is compiled with the No_Dispatching_Calls restriction.
20239 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20240 if we are compiling with restriction No_Dispatching_Calls.
20241 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20242 subprograms if we are compiling under No_Dispatching_Calls restriction.
20243 (Make_DT): Generate a dispatch table with a single dummy entry if
20244 we are compiling with the No_Dispatching_Calls restriction. In
20245 addition, in this case we don't generate code that calls to the
20246 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20247 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20248 of this subprogram if compiling with the No_Dispatching_Calls
20250 (Expand_Type_Conversion): Instead of using the actual parameter,
20251 the argument passed as parameter to the conversion function was
20252 erroneously referenced by the expander.
20253 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20254 Set_Predefined_Primitive_Op_Address and Set_Signature.
20255 (Expand_Dispatching_Call): Generate call to
20256 Get_Predefined_Prim_Op_Address for predefined primitives.
20257 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20258 predefined primitives.
20259 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20260 primitives we reserve one dummy entry to ensure that the tag does not
20261 point to some memory that is associated with some other object. In
20262 addition, remove all the old code that generated the assignments
20263 associated with the signature of the dispatch table and replace them
20264 by a call to the new subprogram Set_Signature.
20265 (Set_All_DT_Position): Change the algorithm because now we have a
20266 separate dispatch table associated with predefined primitive operations.
20267 (Expand_Interface_Conversion): In case of non-static offset_to_top
20268 add explicit dereference to get access to the object after the call
20269 to displace the pointer to the object.
20270 (Expand_Interface_Thunk): Modify the generation of the actual used
20271 in the calls to the run-time function Offset_To_Top to fulfil its
20273 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

20277 * exp_dist.adb (Copy_Specification): For access parameters, copy
20278 Null_Exclusion flag, which will have been set for stream subprograms
20281 2006-02-13 Pascal Obry <obry@adacore.com>
20283 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20284 previous implementation was using the C runtime spawnve routine but
20285 the corresponding wait was using directly the Win32 API. This was
20286 causing some times a lock when waiting for an event using
20287 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20288 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20289 API fixes this problem.
20291 2006-02-13 Robert Dewar <dewar@adacore.com>
20293 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20301 array reference that is an explicit dereference, mark the converted
20302 (packed) array reference as analyzed to prevent a forthcoming
20303 reanalysis from resetting its type to the original (non-packed) array
20306 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20307 Javier Miranda <miranda@adacore.com>
20308 Eric Botcazou <ebotcazou@adacore.com>
20310 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20311 Is_Predefined_Primitive_Operation): When
20312 searching for the predefined equality operator, verify that operands
20313 have the same type.
20314 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20315 for the last entity in the list of aliased subprograms. This code
20316 was wrong in case of renamings.
20317 (Set_Renamed_Subprogram): New procedure
20318 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20319 Exp_Type constant computed when entering this subprogram.
20320 (Known_Null): New function
20321 (OK_To_Do_Constant_Replacement): New function
20322 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20323 (Side_Effect_Free): An attribute reference 'Input is not free of
20324 side effect, unlike other attributes that are functions. (from code
20326 (Remove_Side_Effects): Expressions that involve packed arrays or records
20327 are copied at the point of reference, and therefore must be marked as
20328 renamings of objects.
20329 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20330 not a dispatching operation.
20333 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20334 elementary types in all cases.
20336 2006-02-13 Javier Miranda <miranda@adacore.com>

20339 task types when accessing to the corresponding record type.
20340 Remove '!' in warning message.
20342 2006-02-13 Olivier Hainque <hainque@adacore.com>
20344 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20345 to avoid useless and space inefficient overalignments on targets where
20346 Max_Alignment is larger than 16.
20348 2006-02-13 Pascal Obry <obry@adacore.com>
20350 * g-catiio.adb (Sec_Number): New type used to compute the number of
20351 seconds since 1-1-1970.
20352 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20353 negative numbers (years, months...) it is better to have a Natural here.
20355 (Image) [Number]: Change parameter from Long_Integer to Number.
20356 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20357 overflow for dates past year 2038.
20359 2006-02-13 Matthew Heaney <heaney@adacore.com>
20361 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20364 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20366 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20368 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20369 finalization can occur normally.
20371 2006-02-13 Vincent Celier <celier@adacore.com>
20373 * gnatcmd.adb (Rules_Switches): New table
20374 (Add_To_Rules_Switches): New procedure
20375 (GNATCmd): For command CHECK, put all options following "-rules" in the
20376 Rules_Switches table. Append these -rules switches after the -cargs
20379 2006-02-13 Robert Dewar <dewar@adacore.com>
20381 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20382 These two cases were generating incorrect output, and if this unit
20383 was built with checks on, generated a discriminant mismatch constraint
20386 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20387 Robert Dewar <dewar@adacore.com>
20389 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20390 view is an array type, indicate the component type as well, for
20391 navigation purposes.
20392 (Generate_Reference): Don't consider array ref on LHS to be a case
20393 of violating pragma Unreferenced.
20394 Do not give Ada 2005 warning except on real reference.
20396 2006-02-13 Vincent Celier <celier@adacore.com>
20398 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20399 main source, add switch -mdebug-main=_ada_ so that the executable can
20400 be debugged by the standard VMS debugger.
20401 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20402 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20403 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20404 of the last source, as the binding and linking phases are never
20406 Set all executable obsolete when rebuilding a library.
20408 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20411 2006-02-13 Javier Miranda <miranda@adacore.com>
20414 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20415 code to improve the error message reported when the program has
20416 declarations of abstract interface types and it is not compiled with
20417 the -gnat05 switch.
20418 (P_Access_Definition): Reorganize the code to improve the error
20419 message reported when the new Ada 2005 syntax for anonymous
20420 access types is used and the program is not compiled with the

20434 2006-02-13 Vincent Celier <celier@adacore.com>
20436 * prj.adb (Reset): Initialize the first element of table Namings with
20437 the standard naming data.
20439 2006-02-13 Vincent Celier <celier@adacore.com>
20441 * prj.ads (Error_Warning): New enumeration type
20443 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20444 unknown, use the location of the project to report the error.
20445 (When_No_Sources): New global variable
20446 (Report_No_Ada_Sources): New procedure
20447 (Check): New parameter When_No_Sources. Set value of global variable
20449 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20450 (Get_Sources_From_File): Ditto
20451 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20454 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20455 Call Prj.Proc.Process with parameter When_No_Sources.
20457 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20458 Call Recursive_Check with parameter When_No_Sources.
20459 (Recursive_Check): New parameter When_No_Sources. Call itself and
20460 Prj.Nmsc.Check with parameter When_No_Sources.
20461 (Process): New parameter When_No_Sources. Call Check with parameter
20463 (Copy_Package_Declarations): New procedure to copy renamed parameters
20464 and setting the location of the declared attributes to the location
20465 of the renamed package.

20471 * prj-makr.adb (Make): Preserve the comments from the original project
20473 When removing nodes (attributes Source_Dirs, Source_Files,
20474 Source_List_File and package Naming), save the comments and attach the
20475 saved comments to the newly created nodes.
20476 Do not add a with clause for the naming package if one already exists.

20484 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20485 aliased entities to look for the overriden abstract interface
20487 (Is_Interface_Subprogram): Complete documentation.
20488 (Check_Dispatching_Operation): Do not generate code to register the
20489 operation in the dispatch table if the source is compiled with
20490 restriction No_Dispatching_Calls.
20491 (Override_Dispatching_Operation): Check for illegal attempt to override
20492 No_Return procedure with procedure that is not No_Return
20493 (Check_Dispatching_Call): Suppress the check for an abstract operation
20494 when the original node of an actual is a tag-indeterminate attribute
20495 call, since the attribute, which must be 'Input, can never be abstract.
20496 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20497 call to the Input attribute (even when rewritten).
20498 (Propagate_Tag): Augment comment to indicate the possibility of a call
20499 to an Input attribute.
20501 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20502 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20504 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20505 No_Wide_Characters is no longer partition-wide
20506 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)

20511 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20513 2006-02-13 Javier Miranda <miranda@adacore.com>
20515 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20516 handles default-initialized components to keep separate the management
20517 of this feature but also avoid the unrequired resolution and
20518 expansion of components that do not have partially initialized
20520 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20521 (Check_Bounds): Likewise.
20522 (Check_Length): Likewise.
20524 2006-02-13 Javier Miranda <miranda@adacore.com>
20525 Ed Schonberg <schonberg@adacore.com>
20527 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20528 abstract interface type call analyze_and_resolve to expand the type
20529 conversion into the corresponding displacement of the
20530 reference to the base of the object.
20531 (Eval_Attribute, case Width): For systems where IEEE extended precision
20532 is supported, the maximum exponent occupies 4 decimal digits.
20533 (Accessibility_Message): Add '\' in 2-line warning message.
20534 (Resolve_Attribute): Likewise.
20535 (case Attribute_Access): Significantly revise checks
20536 for illegal access-to-subprogram Access attributes to properly enforce
20537 the rules of 3.10.2(32/2).
20538 Diagnose use of current instance with an illegal attribute.
20540 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20542 (Enclosing_Generic_Unit): New function to return a node's innermost
20543 enclosing generic declaration node.
20544 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20545 (Type_Access_Level): The accessibility level of anonymous acccess types
20546 associated with discriminants is that of the current instance of the
20547 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20548 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20549 (Kill_Current_Values_For_Entity): New function
20550 (Enter_Name): Change formal type to Entity_Id
20552 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20553 Ed Schonberg <schonberg@adacore.com>
20554 Gary Dismukes <dismukes@adacore.com>
20556 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20557 Analyze_Compilation_Unit.
20558 Detect and warn on redundant with clauses detected in a package spec
20559 and/or body when -gnatwr is used.

20561 (Install_Context_Items): Don't analyze config pragmas here
20562 (Install_Limited_Withed_Unit): Set limited entity of package in
20563 with_clause so that cross-reference information or warning messages on
20564 unused packages can be properly generated
20565 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20566 has Error_Posted set. Prevent infinite loops in illegal programs.
20567 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20568 to the point of the error test requiring the current unit to be private.
20569 This ensures that private with clauses are not exempted from the basic
20570 checking for being a descendant of the same library unit parent as a
20571 withed private descendant unit.
20572 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20573 handle private with clauses properly, as well as to account for cases
20574 where the withed unit is a public descendant of a private ancestor
20575 (in which case the current unit must be a descendant of the private
20576 ancestor's parent). The spec comments were updated accordingly. Also,
20577 the old error message in this subprogram was replaced with error
20578 messages that mirror the errors tested and reported by
20579 Check_Private_Child_Unit.
20580 Parameter and variable names improved for readability.
20581 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20582 private as the precondition for calling
20583 Check_Private_Limited_Withed_Unit since that subprogram has been
20584 revised to test public units as well as private units.

20591 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20592 that Scope_Stack.First = 1.
20593 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20594 were not always properly handled previously.

20596 with multiple levels of parametrization by formal packages.
20597 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20598 to the corresponding derived type declaration for proper semantics.
20600 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20601 (Check_Component): Enforce restriction on components of
20602 unchecked_unions: a component in a variant cannot contain tasks or
20604 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20606 Add pragma Ada_2005 (synonym for Ada_05)
20607 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20608 were not always properly handled previously.
20609 Document that pragma Propagate_Exceptions has no effect
20610 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20611 (Set_Convention_From_Pragma): Check that if a convention is
20612 specified for a dispatching operation, then it must be
20613 consistent with the existing convention for the operation.
20614 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20615 longer required to specify an vtable-ptr component in the record. For
20616 compatibility reasons we leave the support for the previous definition.
20617 (Analyze_Pragma, case No_Return): Allow multiple arguments
20619 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20620 non-overrideen inherited operation with a controlling result as
20621 illegal only its implicit declaration comes from the derived type
20622 declaration of its result's type.
20623 (Check_Possible_Deferred_Completion): Relocate the object definition
20624 node of the subtype indication of a deferred constant completion rather
20625 than directly analyzing it. The analysis of the generated subtype will
20626 correctly decorate the GNAT tree.
20627 (Record_Type_Declaration): Check whether this is a declaration for a
20628 limited derived record before analyzing components.
20629 (Analyze_Component_Declaration): Diagnose record types not explicitly
20630 declared limited when a component has a limited type.
20631 (Build_Derived_Record_Type): Code reorganization to check if some of
20632 the inherited subprograms of a tagged type cover interface primitives.
20633 This check was missing in case of a full-type associated with a private
20635 (Constant_Redeclaration): Check that the subtypes of the partial and the
20636 full view of a constrained deferred constant statically match.
20637 (Mentions_T): A reference to the current type in an anonymous access
20638 component declaration must be an entity name.
20639 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20640 class_wide type to refer to full type, not to the incomplete one.
20641 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20642 available. Required to give support to the certified run-time.
20643 (Analyze_Component_Declaration): In case of anonymous access components
20644 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20645 (Process_Discriminants): For an access discriminant, use the
20646 discriminant specification as the associated_node_for_itype, to
20647 simplify accessibility checks.
20649 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20650 Javier Miranda <miranda@adacore.com>
20652 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20653 abstract interpretations on an operator, remove interpretations that
20654 yield Address or a type derived from it, if one of the operands is an
20656 (Try_Object_Operation.Try_Primitive_Operation,
20657 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20658 location when creating the new reference to a primitive or class-wide
20659 operation as a part of rewriting a subprogram call.
20660 (Try_Primitive_Operations): If context requires a function, collect all
20661 interpretations after the first match, because there may be primitive
20662 operations of the same type with the same profile and different return
20663 types. From code reading.
20664 (Try_Primitive_Operation): Use the node kind to choose the proper
20665 operation when a function and a procedure have the same parameter
20667 (Complete_Object_Operation): If formal is an access parameter and prefix
20668 is an object, rewrite as an Access reference, to match signature of
20669 primitive operation.
20670 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20671 by an expanded name with prefix Standard, when the operands are of an
20672 anonymous access type.
20673 (Remove_Abstract_Operations): If the operation is abstract because it is
20674 inherited by a user-defined type derived from Address, remove it as
20675 well from the set of candidate interpretations of an overloaded node.
20676 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20679 2006-02-13 Bob Duff <duff@adacore.com>
20681 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20682 redundant use clauses.
20683 In particular, if the scope of two use clauses overlaps, but one is not
20684 entirely included in the other, we should not warn. This can happen
20685 with nested packages.
20686 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20687 reported errors. The bug was reported when the compiler was built
20688 with assertions enabled.
20689 (Find_Type): If the node is a 'Class reference and the prefix is a
20690 synchronized type without a corresponding record, return the type
20693 2006-02-13 Javier Miranda <miranda@adacore.com>
20695 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20696 if this is the full-declaration associated with a private declaration
20697 that implement interfaces, then the private type declaration must be
20699 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20700 as aliased. The use of the 'access attribute is not available for such
20701 object (for this purpose the object should be explicitly marked as
20702 aliased, but being an anonymous type this is not possible).
20704 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20705 Robert Dewar <dewar@adacore.com>
20707 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20708 compilation unit is an elaboration scope.

20712 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20713 Javier Miranda <miranda@adacore.com>
20715 * sem_type.adb (Write_Overloads): Improve display of candidate
20717 (Add_One_Interp): Do not add to the list of interpretations aliased
20718 entities corresponding with an abstract interface type that is an
20719 immediate ancestor of a tagged type; otherwise we have a dummy
20720 conflict between this entity and the aliased entity.
20721 (Disambiguate): The predefined equality on universal_access is not
20722 usable if there is a user-defined equality with the proper signature,
20723 declared in the same declarative part as the designated type.
20724 (Find_Unique_Type): The universal_access equality operator defined under
20725 AI-230 does not cover pool specific access types.
20726 (Covers): If one of the types is a generic actual subtype, check whether
20727 it matches the partial view of the other type.
20729 2006-02-13 Thomas Quinot <quinot@adacore.com>
20731 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20732 line. This is necessary to allow In_Extended_Main_Unit to provide
20733 correct results for itypes while writing out expanded source.
20734 (Close_File): No need to update the source_index_table here since it's
20735 now done for each line.
20737 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20738 Robert Dewar <dewar@adacore.com>
20740 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20741 preserve the source unit where the itype is declared, and prevent a

20754 2006-02-13 Bob Duff <duff@adacore.com>
20756 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20757 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20758 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20759 raise Constraint_Error.
20761 * s-vallli.adb (Scan_Long_Long_Integer): Call
20762 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20763 do not scan leading blanks and sign twice.
20764 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20765 raise Constraint_Error.
20767 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20768 Scan_Long_Long_Unsigned): Split out most of the processing from
20769 Scan_Long_Long_Unsigned out into
20770 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20771 This prevents scanning leading blanks and sign twice.
20772 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20775 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20776 out most of the processing from Scan_Unsigned out into
20777 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20778 This prevents scanning leading blanks and sign twice.
20780 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20781 use with Modular'Value attribute.
20782 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

20978 Florian Villoing <villoing@adacore.com>
20980 * a-taster.ads, a-taster.adb: New files.
20982 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
20983 link to the version that does nothing. This way the task termination
20984 routine is not executed twice for the environment task when finishing
20985 because of an unhandled exception.
20987 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
20988 handler because of an unhandled exception.
20990 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
20991 System.Tasking.Utilities instead of that in System.Tasking.Stages.
20993 * s-finimp.adb (initialization code): Modify the soft link for the
20994 finalization of the global list instead of Adafinal.
20996 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
20997 non-tasking version of the soft link for task termination. We do
20998 nothing since if we are using the non-tasking version it
20999 means that the task termination functionality is not used.
21000 (Null_Finalize_Global_List): Add this null version for the procedure
21001 in charge of finalizing the global list for controlled objects.
21002 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21003 instead for handling run-time termination in a more flexible way.
21004 (Adafinal_NT): This new procedure will take care of finalizing the
21005 global list for controlled objects if needed, but no tasking
21008 * s-tarest.adb (Task_Lock): Do not try to lock again the
21009 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21010 some run-time operations.
21011 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21012 until all nested locks have been released.
21013 (Task_Wrapper): Call the fall-back task termination handler. It
21014 applies to all tasks but the environment task.
21015 (Finalize_Global_Tasks): Add the call for the task termination
21016 procedure for the environment task.
21017 (Task_Wrapper): suppress warnings around declaration of
21018 Secondary_Stack_Address.
21020 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21021 moved to the Common_ATCB record.
21022 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21023 Common_ATCB record.
21024 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21025 Common_ATCB record.
21027 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21028 Fall_Back_Handler, and Specific_Handler.
21030 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21031 defined in Ada.Task_Termination, to avoid circular dependencies.
21032 (Termination_Handler): Redefine this type here, alredy defined in
21033 Ada.Task_Termination, for avoiding circular dependencies.
21034 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21035 for storing task termination handlers. In addition,
21036 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21037 Common_ATCB because it is used by both the regular and the restricted
21039 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21040 Common_ATCB because it is used by both the regular and the restricted
21042 (Common_ATCB): Added a dynamic task analyzer field.
21044 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21045 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21046 (Task_Wrapper): Call the task termination handler. It applies to all
21047 tasks but the environment task.
21048 (Finalize_Global_Tasks): Call the task termination procedure for the
21049 environment task. The call to Finalize_Global_List is now performed
21050 using the soft links mechanism.
21051 (Task_Wrapper): added dynamic stack analysis.
21053 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21054 potentially blocking operations has been moved from
21055 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21056 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21057 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21058 this run-time check.
21060 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21061 of task termination procedure.
21062 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21063 link for the task termination procedure.
21065 * bindusg.adb: (Bindusg): Added documentation for -u option.

21078 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21079 (Standart_Output): new subprogram
21080 (Set_Output): new subprogram
21081 (Put): now uses the value of Current_Out to know if the output has to be
21082 send to stderr or stdout.
21084 * s-stausa.ads: Complete implementation.
21086 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21088 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21089 list of Ada 05 files.
21090 (GNAT Library Units): Add AltiVec files.
21092 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
21093 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21094 g-alvety.ads, g-alvevi.ads: New files providing altivec API.

21098 * adaint.c (__gnat_locate_regular_file): Return immediately if
21099 file_name is empty.
21101 2005-12-09 Javier Miranda <miranda@adacore.com>
21102 Hristian Kirtchev <kirtchev@adacore.com>
21104 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21105 to the specification because the frontend generates code that uses this
21107 (Set_Interface_Table): Add missing assertion.
21108 Update documentation describing the run-time structure.
21109 (Displace): New subprogram that displaces the pointer to the object
21110 to reference one of its secondary dispatch tables.
21111 (IW_Membership): Modified to use the new table of interfaces.
21112 (Inherit_TSD): Modified to use the new table of interfaces.
21113 (Register_Interface_Tag): Use the additional formal to fill the
21114 contents of the new table of interfaces.
21115 (Set_Interface_Table): New subprogram that stores in the TSD the
21116 pointer to the table of interfaces.
21117 (Set_Offset_To_Top): Use the additional formal to save copy of
21118 the offset value in the table of interfaces.
21119 Update structure of GNAT Primary and Secondary dispatch table diagram.
21120 Add comment section on GNAT dispatch table prologue.
21121 (Offset_To_Signature): Update the constant value of the Signature field.
21122 (Dispatch_Table): Update comment on hidden fields in the prologue.

21125 the type of formal parameter T to Tag, introduce additional assertions.
21126 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
21128 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
21130 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21131 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21132 record component containing the tag of the secondary dispatch table we
21133 have to use the Offset_To_Top run-time function to get this information;
21134 otherwise if the pointer to the base of the object has been displace
21135 we get a wrong value if we use the 'position attribute.
21137 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21138 all the calls to Expand_Interface_Thunk.
21139 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21140 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21141 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21142 ensure that the interfaces implemented by the ancestors are placed
21143 at the header of the generated list.
21144 (Expand_Interface_Conversion): Handle the case in which the displacement
21145 associated with the interface conversion is not statically known. In
21146 this case we generate a call to the new run-time subprogram Displace.
21147 (Make_DT): Generate and fill the new table of interfaces.
21148 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21149 Get_Tagged_Kind and Set_Tagged_Kind.
21150 (Tagged_Kind): New function that determines the tagged kind of a type
21151 with respect to limitedness and concurrency and returns a reference to
21153 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21154 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21155 primary dispatch table for a type.
21156 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
21157 secondary dispatch table respectively of a tagged type.
21159 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21160 (Expand_Interface_Conversion): New subprogram to indicate if the
21161 displacement of the type conversion is statically known.
21162 (DT_Access_Action): Add values Get_Tagged_Kind and Set_Tagged_Kind.
21164 * rtsfind.ads (RE_Offset_To_Top): New entity
21165 (RTU_Id): Add Ada_Task_Termination to the list so that it is made
21166 accessible to users.
21167 (Re_Displace): New entity
21168 (RE_Interface_Data): New entity
21169 (RE_Set_Interface_Data): New_Entity
21170 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,

21379 legal within a protected type that implements an interface.
21380 (Collect_Interfaces): Do not add to the list the interfaces that
21381 are implemented by the ancestors.
21382 (Derived_Type_Declaration): If the parent of the full-view is an
21383 interface perform a transformation of the tree to ensure that it has
21384 the same parent than the partial-view. This simplifies the job of the
21385 expander in order to generate the correct object layout, and it is
21386 needed because the list of interfaces of the full-view can be given in
21388 (Process_Full_View): The parent of the full-view does not need to be
21389 a descendant of the parent of the partial view if both parents are

21406 (Process_Full_View): Improve the check for the "no hidden interface"
21407 rule as defined by AI-396.
21409 2005-12-09 Robert Dewar <dewar@adacore.com>

21466 available user-specified stream attributes on limited parameters to
21467 also test the type directly rather than only its underlying type (for
21468 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21469 attributes are visible at the point of the subprogram declaration.
21470 For Ada 2005, the error message is modified to indicate that the
21471 type's stream attributes must be visible (again, only for -gnat05).

21503 types use the corresponding record type. This was not needed before
21504 the implementation of Ada 2005 synchronized types because
21505 concurrent types were never tagged types in Ada 95.

21751 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for

21806 Increase default priority on Lynx from 15 to 17, and meet the Ada
21807 requirement that Default_Priority be ((Priority'First +

21910 we are not defining the type.
21911 <E_Record_Type>: Likewise.
21912 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21913 to get advantage of the new maybe_stabilize_reference interface, to
21914 ensure that what we reference is indeed stabilized instead of relying
21915 on assumptions on what the stabilizer does.
21916 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21917 type imported through a limited_with clause, use its non-limited view.
21918 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

21921 of #if sections + explicit comparisons of convention identifiers.

21923 before early-returning for certain types when code generation is

21927 that we are not defining.
21928 (elaborate_expression_1): Do not create constants when creating
21929 variables needed by the debug info: the dwarf2 writer considers that
21930 CONST_DECLs is used only to represent enumeration constants, and emits
21932 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21933 object with an address clause into an indirect reference, drop the
21934 initializing expression.

21946 subtype to build an actual type with bounds template.
21947 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21948 is provided by the front-end, use that subtype to compute the size of
21949 the deallocated object.

21957 without need to check for the success indication.
21958 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21959 pass false instead of 0 as the FORCE argument which is a bool.
21960 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21961 attached to a renaming pointer has been properly stabilized, as no such
21962 object is attached otherwise.
21963 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21964 function uses the "target pointer" return mechanism.
21965 Reinstate conversion of the actual to the type of the formal
21966 parameter before any other specific treatment based on the passing

21977 static output of record constructor if all the components are constant.
21978 (gnat_build_constructor): For a record type, sort the list of field
21979 initializers in increasing bit position order.
21980 Factor common code to build a storage type for an unconstrained object
21981 from a fat or thin pointer type and a constrained object type.
21982 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
21983 types variants, and process special cases of VIEW_CONVERT expressions
21984 as their NOP_EXPR counterpart to ensure we get to the
21985 CORRESPONDING_VARs associated with CONST_DECls.
21986 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
21987 on the right-hand side.

21994 extracting the object if converting to a type variant.
21995 (create_var_decl): When a variable has an initializer requiring code
21996 generation and we are at the top level, check for a potential violation
21997 of a No_Elaboration_Code restriction.
21998 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN

22144 nested aggregate, the object may appear in the wrong scope.
22145 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
22146 (Gen_Assign): If the component being assigned is an array type and the
22147 expression is itself an aggregate, wrap the assignment in a block to
22148 force finalization actions on the temporary created for each row of the
22150 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
22151 structures are initialized after all discriminants are set so that
22152 they can be accessed even when their offset is dynamic.

22180 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22181 and related): For a prefix that is an explicit dereference of an

22183 with an actual subtype so GIGI can make a correct size computation.
22184 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22185 'Unrestricted_Access, if the designated type is an interface we
22186 add a type conversion to force the displacement of the pointer
22187 to the secondary dispatch table.
22188 Use Universal_Real instead of Long_Long_Float when we need a high
22189 precision float type for the generated code (prevents gratuitous
22190 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22191 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22192 'Terminated for task interface class-wide objects. Generate a call to

22220 for any entity whose value is known from the condition of the first
22222 (Expand_N_Return_Statement): When returning a mutable record, convert
22223 the return value into its actual subtype in order to help the backend
22224 to return the actual size instead of the maximum. This is another

22274 attribute of the N_Free_Statement.
22275 Generate itype for classwide designated object in both cases of
22276 user-specified storage pool: specific and class-wide, not only in the
22278 Raise CE when trying to set a not null access type object to null.

22458 rhs of an assignment even if the type is unconstrained, when the
22459 context is non-expanding.
22460 In an inlined body, if the context type is private,

22517 scope against package Standard. Add comments and a ??? comment.
22518 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22519 on a child instance parent to test that the parent equals

22539 full view to construct the full declaration of the derived type.
22540 (Build_Derived_Record_Type): Relax the condition that controls the
22541 execution of the check that verifies that the partial view and

22551 (Process_Full_View): Rename local subprogram Find_Interface_In_
22552 Descendant to Find_Ancestor_Interface to leave the code more clear.
22553 Remove wrong code that avoids the generation of an error message
22554 when the immediate ancestor of the partial view is an interface.
22555 In addition some minor reorganization of the code has been done to
22556 leave it more clear.
22557 (Analyze_Type_Declaration): If type has previous incomplete tagged
22558 partial view, inherit properly its primitive operations.
22559 (Collect_Interfaces): Make public, for analysis of formal

22572 be included in the interface list.
22573 (Access_Definition): If the designated type is an interface that may
22574 contain tasks, create Master_Id for it before analyzing the expression
22575 of the declaration, which may be an allocator.

22577 in allocators, the creation of master id's for task interfaces, etc.

22586 subprogram declaration.
22587 Change name Is_Package to Is_Package_Or_Generic_Package
22588 (Process_Formals): A non null qualifier on a non null named access
22589 type is not an error, and is a warning only if Redundant_Constructs

22593 Ed Schonberg <schonberg@adacore.com>
22595 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure

22600 package associated with a generic instance or formal package, the
22601 private declarations of the parent must be installed (by calling new

22603 Change name Is_Package to Is_Package_Or_Generic_Package
22604 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22610 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22611 not try to rewrite a renamed stream attribute, because the operations
22612 on the type may not have been generated.
22613 Handle properly a renaming_as_body generated for a stream operation
22614 whose default is abstract because the object type itself is abstract.
22615 (Find_Type): If the type is incomplete and appears as the prefix of a
22616 'Class reference, it is tagged, and its list of primitive operations
22617 must be initialized properly.

22619 private declaration of a parent unit, prior to compiling the private
22620 part of a child unit, find on the scope stack the proper parent entity
22621 on which to link the use clause.

22653 (Resolve_Concatenation_Arg): Improve error message when argument is an
22654 ambiguous call to a function that returns an array.
22655 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

22669 with assertions enabled gives the same output that its
22670 compilation without assertions.

22672 Change name In_Actual to In_Generic_Actual (clean up)
22673 (Disambiguate): New predicate In_Actual, to recognize expressions that

23356 used in dispatching selects.
23357 (Init_Predefined_Interface_Primitives): Remove the hardcoded number of
23358 predefined primitive operations and replace it with
23359 Default_Prim_Op_Count.
23360 (Make_Disp_Asynchronous_Select_Spec, Make_Disp_Conditional_Select_Spec,
23361 Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
23362 the names of the generated primitive operations used in dispatching
23364 (Init_Predefined_Interface_Primitives): No need to inherit primitives in
23365 case of abstract interface types. They will be inherit by the objects
23366 implementing the interface.
23367 (Make_DT): There is no need to inherit the dispatch table of the
23368 ancestor interface for the elaboration of abstract interface types.
23369 The dispatch table will be inherited by the object implementing the
23371 (Copy_Secondary_DTs): Add documentation.

23376 the entries associated with predefined primitives of all the secondary
23378 (Build_Anonymous_Access_Type): Removed.
23379 (Expand_Interface_Actuals): With the previous cleanup there is no need
23380 to build an anonymous access type. This allows further cleanup in the
23381 code generated by the expander.
23382 (Expand_Interface_Conversion): If the actual is an access type then
23383 build an internal function to handle the displacement. If the actual
23384 is null this function returns null because no displacement is
23385 required; otherwise performs a type conversion that will be
23386 expanded in the code that returns the value of the displaced actual.
23387 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23388 conversions that have no effect in the generated code because no
23389 displacement is required. Code cleanup; use local variables to
23390 avoid repeated calls to the subprogram directly_designated_type().

23397 implements a limited interface.
23398 (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
23399 (Expand_Subtype_From_Expr): Do not build actual subtype if the
23400 expression is limited.
23401 (Find_Interface_Tag): Add code to handle class-wide types and
23402 entities from the limited-view.
23404 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
23405 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,

23430 Move with clauses outside Warnings Off now that dependent units are
23432 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
23433 initialization of this unit.
23434 (Specific): Add new procedures Initialize and Delete so that this
23435 package can be used for VxWorks 5.x and 6.x
23436 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
23437 differences between VxWorks 5.x and 6.x
23438 Minor reformatting.
23439 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by
23441 Use only Preelaborate-compatible constructs.

23455 (Set_Time_Slice): New function, replacing kerneltimeSlice to share code
23456 between Vxworks 5 and 6.
23457 (taskLock, taskUnlock): Removeed, no longer used.
23459 * adaint.c: The wait.h header is not located in the sys directory on
23460 VxWorks when using RTPs.
23461 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
23463 (__gnat_dup): dup is available on Vxworks when using RTPs.
23464 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
23466 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
23468 * expect.c: The wait.h header is not located in the sys directory on
23469 VxWorks when using RTPs.

23488 set of constants that is consistent with the contents of g-soccon.ads.
23490 * gsocket.h: Code imported from gen-soccon.c:
23491 Move all target-specific file inclusions and macro definitions to
23492 gsocket.h, in order to ensure that any C code in socket.c will see a set
23493 of constants that is consistent with the contents of g-soccon.ads.
23494 This change also makes gen-soccon self-contained (removing dependencies
23495 upon GCC internal headers).
23497 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
23499 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
23501 * socket.c: Minor reformatting.

23633 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23634 from object notation, the original node is unanalyzed and carries no
23635 semantic information, so that accessiblity checks must be performed on
23636 the type of the actual itself.

23649 load comes from a Limited_With_Clause.
23651 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23652 whether a potential circularity is harmless, because it includes units
23653 loaded through a limited_with clause. Extends previous treatment which
23654 did not handle properly arbitrary combinations of limited and
23655 non-limited clauses.

23692 position set is provided, we compute one in order to reduce the maximum
23693 length of the keys. This computation first selects a character
23694 position between 1 and the minimum length of the keys in order to
23695 avoid reducing one of the keys to an empty string.
23696 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23697 does not converge. The initialization procedure now comes with a
23698 maximum number of iterations such that when exceeded, an exception is
23699 raised in Compute. The user can initialize this ratio to another value

23706 that given an entity T creates and returns an Itype that duplicates the
23707 contents of T. The returned Itype has the null-exclusion
23708 attribute set to True, and its Etype attribute references T
23709 to keep the association between the two entities.
23710 Update copyright notice
23712 * sem_aggr.adb (Check_Can_Never_Be_Null,
23713 Aggregate_Constraint_Checks, Resolve_Aggregate,

23734 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23735 instead of Set_Subtype_Mark.
23737 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23738 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23739 (Result_Definition): New function for N_Function_Specifications.
23740 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23741 N_Function_Specification.
23742 (Set_Null_Exclusion_Present): Allow this flag for
23743 N_Function_Specification.
23744 (Set_Result_Definition): New procedure for N_Function_Specifications.
23745 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23746 and N_Function_Specification.
23748 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23749 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23750 Add support for LIMITED NEW for Ada 2005 AI-419
23751 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23752 syntax for anonymous access results.
23753 Replace Subtype_Mark field by Result_Definition in
23754 N_Function_Specification and N_Access_Definition specs.
23755 Add Null_Exclusion_Present to spec of N_Function_Specification.
23756 (Result_Definition): New function for N_Function_Specification and
23757 N_Access_Function_Definition.
23758 (Set_Result_Definition): New procedure for N_Function_Specification and
23759 N_Access_Function_Definition.
23761 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23762 Result_Definition for cases of N_Access_Function_Definition and
23763 N_Function_Specification.
23764 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23766 2005-09-01 Vincent Celier <celier@adacore.com>
23768 * lib-writ.adb: Update Copyright notice
23769 (Write_With_Lines): On platforms where file names are case-insensitive,
23770 record the file names in lower case.
23771 (Write_ALI): For D lines, on platforms where file names are
23772 case-insensitive, record the file names in lower case.
23774 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23775 Emmanuel Briot <briot@adacore.com>

23791 including those that are inherited.
23793 2005-09-01 Robert Dewar <dewar@adacore.com>
23795 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23797 * par-prag.adb: Implement new pragma Debug_Policy
23799 * sem_prag.adb Implement new pragma Debug_Policy
23800 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23801 Component_Size attribute specification. Give warning for ignored pragma
23804 * snames.h, snames.ads, snames.adb: Introduce entries in
23805 Preset_Names for Name_Disp_Asynchronous_Select,
23806 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23807 Name_Disp_Timed_Select.
23808 New pragma Debug_Policy
23810 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23812 Switch -gnata also sets Debug_Pragmas_Enabled
23814 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23815 handle an explicit -gnata when compiling predefined files.
23817 2005-09-01 Vincent Celier <celier@adacore.com>
23819 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23820 directories of projects that have no Ada sources.
23822 2005-09-01 Robert Dewar <dewar@adacore.com>
23824 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23825 (makes a difference for wide characters)
23827 * widechar.adb, widechar.ads:
23828 Add Wide_Char_Byte_Count feature to count chars vs bytes
23830 2005-09-01 Thomas Quinot <quinot@adacore.com>
23831 Ed Schonberg <schonberg@adacore.com>
23832 Robert Dewar <dewar@adacore.com>
23834 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23835 'Address attribute reference with an overloaded prefix, use the
23836 location of the prefix (not the location of the attribute reference) as
23837 the error location.
23838 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23839 a function renaming thereof, is a valid prefix for 'Size (where it is
23840 intepreted as a function call).
23841 (Statically_Denotes_Entity): New predicate to determine whether the
23842 prefix of an array attribute can be considered static.
23845 (Eval_Attr): Fix failure to evaluate Component_Size for
23846 unconstrained arrays (resulted in wrong value in packed case, since
23847 back end cannot handle this case)
23849 2005-09-01 Robert Dewar <dewar@adacore.com>
23851 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23852 error msgs for most common cases.
23853 Use new errout insertion char < (conditional warning)
23855 2005-09-01 Javier Miranda <miranda@adacore.com>
23856 Ed Schonberg <schonberg@adacore.com>
23858 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23859 become local to the whole package.
23860 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23861 the package was already analyzed the new algorithm "replaces" the
23862 real entities by the shadow ones. This is required to ensure that
23863 the order of these entities in the homonym chains does not change;
23864 otherwise we can have undefined references at linking time because
23865 in case of conflicts the external name of the entities will have
23866 a suffix that depends on the order of the entities in the chain.
23867 (Remove_Limited_With_Clause): Complementary code that completes the
23868 new algorithm and replaces the shadow entities by the real ones.
23869 (Install_Limited_Withed_Unit): When unchaining entities before the
23870 installation of the shadow entities, only regular entities of the
23871 public part must be taken into account. This is required to
23872 keep this routine in synch with the work done by Remove_Limited_
23874 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23875 even if unit is analyzed, because the analysis of the unit is
23876 idempotent in any case, and the limited view of the unit may have to
23877 be installed for proper visibility.
23878 (Expand_Limited_With_Clause): Even if the unit in the implicit
23879 with_clause has been analyzed already, a limited view of the package
23880 must be built for the current context, if it does not exist yet.
23882 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23883 Javier Miranda <miranda@adacore.com>
23884 Gary Dismukes <dismukes@adacore.com>
23886 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23887 defining entity for the instance body, make a new defining identifier
23888 rather than copying the entity of the spec, to prevent accidental
23889 sharing of the entity list.
23890 (Check_Private_View): When exchanging views of private types, build the
23891 list of exchanged views as a stack, to ensure that on exit the exchanges
23892 are undone in the proper order.
23893 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23894 Restore the compilation environment in case of instantiation_error.
23895 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23896 for an anonymous access result.
23897 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23898 (Formal_Entity): Handle properly the case of a formal package that
23899 denotes a generic package renaming.
23901 2005-09-01 Thomas Quinot <quinot@adacore.com>
23903 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23904 clause if the array aggregate is surrounded by parentheses.
23906 2005-09-01 Cyrille Comar <comar@adacore.com>
23907 Gary Dismukes <dismukes@adacore.com>
23908 Ed Schonberg <schonberg@adacore.com>
23909 Javier Miranda <miranda@adacore.com>
23911 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23913 to check if a type is Constrained in cases related to code generation
23914 (rather than semantic checking) since otherwise we do not generate
23915 similar code for mutable private types depending if their
23916 discriminants are visible or not.
23917 (Check_Abstract_Overriding): Do not complain about failure to override
23918 the primitive operations used in dispatching selects since they will
23919 always be overriden at the freeze point of the type.
23920 (Access_Definition): Separate out handling for resetting the scope
23921 of an anonymous access function result type. Retrieve the scope
23922 of the associated function rather than using Current_Scope, which
23923 does not have a consistent value (depends on whether we're in the
23924 middle of analyzing formal parameters). Add ??? comment about
23925 finding a cleaner way to handle the special cases of scope setting.
23926 (Process_Incomplete_Dependents): A protected operation is never a
23927 dispatching operation (only its wrapper may be).
23928 (Build_Derived_Record_Type): In case of tagged private types that
23929 implement interfaces add derivation of predefined primitive
23931 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23932 by two parameters that are used in case of derivation from abstract
23933 interface types: No_Predefined_Prims is used to avoid the derivation
23934 of predefined primitives from the interface, and Predefined
23935 Prims_Only is used to complete the derivation predefined primitives
23936 in case of private tagged types implementing interfaces.
23937 Fix typo in comments
23938 (Find_Interface_In_Descendant): Protect the frontend against
23939 wrong code with large circularity chains.
23940 (Is_Private_Overriding): Add support for entities overriding interface
23941 subprograms. The test failed because Entities associated with overriden
23942 interface subprograms are always marked as hidden (and used to build
23943 the secondary dispatch table); in this case the overriden entity is
23944 available through the field abstract_interface_alias (cf. override_
23945 dispatching_operation)
23946 (Access_Definition): Set the scope of the type to Current_Scope for the
23947 case of a function with an anonymous access result type.
23948 (Access_Subprogram_Declaration): Handle creation of the type entity for
23949 an access-to-function type with an anonymous access result.
23950 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23951 in handling for N_Access_Function_Definition.
23952 (Analyze_Subtype_Declaration): Modify the text of error message.
23953 (Derived_Type_Declaration): Modify the text of error message.
23954 (Process_Subtype): Modify the text of error message plus cleanup
23955 of one redundant error message.
23956 (Analyze_Component_Declaration): Code cleanup.
23957 (Analyze_Object_Declaration): Code cleanup.
23958 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23959 attribute in case of access types. Code cleanup.
23960 (Array_Type_Declaration): Code cleanup.
23961 (Process_Discriminants): Create the new null-excluding itype
23962 if required. Code cleanup.
23963 (Process_Subtype): Create the new null-excluding itype if
23964 required. Code cleanup.
23965 (Build_Derived_Record_Type): Code cleanup to avoid calling
23966 twice the subprogram derive_subprograms in case of private
23967 types that implement interfaces. In this particular case the
23968 subprogram Complete_Subprograms_Derivation already does the
23969 job associated with the second call.
23971 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23972 conversion to the full view when generating an operation for a
23973 discriminant whose type may currently be private.
23975 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23976 Javier Miranda <miranda@adacore.com>
23978 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23979 V (Obj.F), the rewriting does not involve the indexed component, but
23980 only the selected component itself.
23981 Do not apply the transformation if the analyzed node is an actual of a
23982 call to another subprogram.
23983 (Complete_Object_Operation): Retain the entity of the
23984 dispatching operation in the selector of the rewritten node. The
23985 entity will be used in the expansion of dispatching selects.
23986 (Analyze_One_Call): Improve location of the error message associated
23988 (Analyze_Selected_Component): No need to resolve prefix when it is a
23989 function call, resolution is done when parent node is resolved, as
23991 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23992 when attempting to resolve a call transformed from its object notation.
23993 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23994 of the argument list for each interpretation of the operation.
23995 (Try_Object_Operation): The designated type of an access parameter may
23996 be an incomplete type obtained through a limited_with clause, in which
23997 case the primitive operations of the type are retrieved from its full
23999 (Analyze_Call): If this is an indirect call, and the return type of the
24000 access_to_subprogram is incomplete, use its full view if available.
24002 2005-09-01 Javier Miranda <miranda@adacore.com>
24003 Gary Dismukes <dismukes@adacore.com>
24005 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24006 access types the null-exclusion and access-to-constant attributes must
24008 (Analyze_Return_Statement): When the result type is an anonymous access
24009 type, apply a conversion of the return expression to the access type
24010 to ensure that appropriate accessibility checks are performed.
24011 (Analyze_Return_Type): For the case of an anonymous access result type,
24012 generate the Itype and set Is_Local_Anonymous_Access on the type.
24013 Add ??? placeholder for check to disallow returning a limited object
24014 in Ada 2005 unless it's an aggregate or a result of a function call.
24015 Change calls from Subtype_Mark to Result_Definition.
24016 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24017 Result_Definition in call to Make_Function_Specification.
24018 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24019 Set_Result_Definition.
24020 (Make_Inequality_Operator): Change formal Subtype_Mark to
24021 Result_Definition in call to Make_Function_Specification.
24022 (Process_Formals): Create the new null-excluding itype if required.
24023 (New_Overloaded_Entity): For an entity overriding an interface primitive
24024 check if the entity also covers other abstract subprograms in the same
24025 scope. This is required to handle the general case, that is, overriding
24026 other interface primitives and overriding abstract subprograms inherited
24027 from some abstract ancestor type.
24028 (New_Overloaded_Entity): For an overriding entity that comes from
24029 source, note the operation that it overrides.
24030 (Check_Conformance, Type_Conformant): Addition of one new formal
24031 to skip controlling formals in the analysis. This is used to
24032 handle overloading of abstract interfaces.
24033 (Base_Types_Match): Add missing case for types imported from
24034 limited-with clauses
24035 (New_Overloaded_Entity): Add barrier to protect the use of
24036 the "alias" attribute.
24038 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24040 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24041 verify that the procedure and the entry are mode conformant.
24042 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24043 as a different operator, which is often a cut-and-paste error.
24045 2005-09-01 Javier Miranda <miranda@adacore.com>
24046 Ed Schonberg <schonberg@adacore.com>
24048 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24049 used in controlling parameters exclude null because it is necessary to
24050 read the tag to dispatch, and null has no tag.
24051 (Override_Dispatching_Operation): If the previous operation is inherited
24052 from an interface, it becomes hidden and does not participate in later
24055 2005-09-01 Javier Miranda <miranda@adacore.com>
24056 Ed Schonberg <schonberg@adacore.com>
24057 Gary Dismukes <dismukes@adacore.com>
24059 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24060 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24061 the expander will generate the corresponding run-time check to evaluate
24063 (Resolve_Call): Check for legal type of procedure name or prefix that
24064 appears as a trigger in a triggering alternative.
24065 (Valid_Conversion): If expression is ambiguous and the context involves
24066 an extension of System, remove System.Address interpretations.
24067 (Resolve_Qualified_Expression): Reject the case of a specific-type
24068 qualification applied to a class-wide argument. Enhance comment
24069 to explain checking of Original_Node.
24070 (Resolve_Type_Conversion): The location of the error message was not
24071 general enough to handle the general case and hence it has been removed.
24072 In addition, this patch improves the text of the message.
24073 (Resolve_Type_Conversion): Add missing support for access to interface
24075 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24076 do not expand if the expression is the actual in a call, because proper
24077 expansion will take place when the call itself is expanded.
24078 (Resolve_Allocator): If the context is an unchecked conversion, the
24079 allocator inherits its storage pool, if any, from the target type of
24082 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24083 Javier Miranda <miranda@adacore.com>
24085 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24086 inherited interface operation that has an implementation, use the
24087 implementation to avoid spurious ambiguities.
24088 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24089 use the Corresponding_Record_Typ attribute to look for the interface
24090 because it is set by the expander (and hence it is not always
24091 available). For this reason we traverse the list of interfaces
24092 (available in the parent of the concurrent type).
24093 (Interface_Present_In_Ancestor): Handle entities from the limited view
24095 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24097 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24098 from the list of required components.
24099 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24100 primitive procedure of a limited interface with a controlling first
24102 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24104 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24105 capture if it is generated in the second operand of a short-circuit
24107 Do not capture values for variables with address clauses.
24108 (Is_Object_Reference): Treat a function call as an object reference only
24109 if its type is not Standard_Void_Type.
24111 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24113 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24114 to a variable that is statically known to be constant.

24126 Document that bounds of result of Base_Name match the input index
24128 Add documentation on environment variable syntax for Expand_Path
24130 * gnat_ugn.texi: Update documentation to include mention of -m switches
24131 Document new treatment of wide characters in max line length
24133 Remove -gnatL/-gnatZ switches, no longer used.
24134 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24137 * gnat_rm.texi: Add doc for two argument form of pragma
24138 Float_Representation.
24139 Add documentation for pragma No_Strict_Aliasing
24140 Add note that explicit component clause overrides pragma Pack.
24141 Add documentation of pragma Debug_Policy

24734 Eric Botcazou <ebotcazou@adacore.com>
24736 * s-mastop-irix.adb (Pop_Frame): Revert shorcuts avoiding calls to
24737 exc_unwind, now that we are generating proper .debug_frame output for
24740 * tracebak.c: Remove the mips-irix section, as we are now using the
24741 s-mastop based unwinder again.
24742 Under SPARC/Solaris, take into account the stack bias to compute the
24743 frame offset. The stack bias is 0 for the V8 ABI and 2047 for the V9

24896 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24897 longer protected objects. They have been replaced by lower-level
24898 suspension objects made up by a mutex and a condition variable (or
24899 their equivalent given a particular OS) plus some internal data to
24900 reflect the state of the suspension object.
24901 (Initialize, Finalize): Add this initialization procedure for
24902 Suspension_Object, which is a controlled type.
24903 (Finalize): Add the finalization procedure for Suspension_Object,
24904 which is a controlled type.
24906 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24907 Ada.Synchronous_Task_Control because there is no longer a need for a
24908 VxWorks specific version of this package. Target dependencies
24909 has been moved to System.Task_Primitives.Operations.
24911 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24913 (InitializeCriticalSection, EnterCriticalSection,
24914 LeaveCriticalSection, DeleteCriticalSection): Replace the type
24915 pCriticalSection by an anonymous access type so that we avoid problems
24916 of accessibility to local objects.
24918 * s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,

24922 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
24923 set the environment task mask here.
24924 (Current_State): Add this function that returns the state of the
24926 (Set_False): Add this procedure that sets the state of the suspension
24928 (Set_True): Add this procedure that sets the state of the suspension
24929 object to True, releasing the task that was suspended, if any.
24930 (Suspend_Until_True): Add this procedure that blocks the calling task
24931 until the state of the object is True. Program_Error is raised if
24932 another task is already waiting on that suspension object.
24933 (Initialize): Add this procedure for initializing the suspension
24934 object. It initializes the mutex and the condition variable which are
24935 used for synchronization and queuing, and it sets the internal state
24937 (Finalize): Add this procedure for finalizing the suspension object,
24938 destroying the mutex and the condition variable.

24943 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
24944 which provides a low-level abstraction (using operating system
24945 primitives) for Ada.Synchronous_Task_Control.
24946 This object is made up by a mutex (for ensuring mutual exclusion), a
24947 condition variable (for queuing threads until the condition is
24948 signaled), a Boolean (State) indicating whether the object is open,
24949 and a Boolean (Waiting) reflecting whether there is a task already
24950 suspended on this object.

25143 * exp_ch5.adb (Expand_N_Return_Statement): When a function's result
25144 type is a class-wide type, emit a run-time check that the accessibility

25215 type derivation of private tagged types implementing interfaces.
25216 In this case some interface primitives may have been overriden

25306 * i-cpp.ads, i-cpp.adb:
25307 This package has been left available for compatibility with previous
25308 versions of the frontend. As part of the new layout this is now a

25352 (Analyze_Subprogram_Body): Undo the previous work.
25353 (Analyze_Procedure_Call): If the call has the form Object.Op, the

25362 access to subprograms must be recursive.
25363 (Is_Unchecked_Conversion): Improve the test that recognizes
25364 instantiations of Unchecked_Conversion, and allows them in bodies that
25365 are to be inlined by the front-end. When the body comes from an
25366 instantiation, a reference to Unchecked_Conversion will be an
25367 Expanded_Name, even though the body has not been analyzed yet.

25388 object or component (that is, when Is_Local_Anonymous_Access is true).
25389 Prevent the special checks for conversions of access discriminants in
25390 the case where the discriminant belongs to a nonlimited type, since
25391 such discriminants have their accessibility level defined in the same
25392 way as a normal component of an anonymous access type.
25393 (Resolve_Allocator): When an allocator's designated type is a class-wide
25394 type, check that the accessibility level of type given in the
25395 allocator's expression or subtype indication is not statically deeper

26374 (check dos line terminator).
26375 (Check_Line_Max_Length): New procedure, split off from the existing
26376 Check_Line_Terminator routine. Separating this out allows -gnatyf to
26377 be properly recognized.
26379 * styleg.adb: Add ??? comment for line terminator reference
26381 * scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored

26422 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26423 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26424 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26425 analyzed if expansion is disabled (which could otherwise cause spurious
26426 error messages if expansion has been disabled due to previous
26427 (unrelated) errors).
26429 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26430 is disabled, the entity denoted by the argument is the access type
26431 itself, not an underlying record type, so there is no need to go back
26432 to the Corresponding_Remote_Type.
26434 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26435 Robert Dewar <dewar@adacore.com>
26437 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26438 expand a call to an instance of
26439 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26442 denotes a type in the class.
26443 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26444 of Name_Generic_Dispatching_Constructor.
26446 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26462 generic formal subprogram association for an abstract formal subprogram.
26463 Check that the attribute is a primitive stream attribute (and not
26464 a class-wide stream attribute) and then rewrite the attribute name
26465 as the name of the appropriate compiler-generated stream primitive.

26477 itype whose parent is controlled and not yet frozen, do not create a
26478 freeze node for the itype if expansion is disabled.
26480 2005-03-29 Vincent Celier <celier@adacore.com>
26482 * make.adb (Gnatmake): Don't fail if the main project file is declared
26483 as having no Ada sources. Do not display message "no sources to
26484 compile" in quiet output.

26504 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26505 rather than proceed ahead using a junk attribute name.
26507 2005-03-29 Vincent Celier <celier@adacore.com>
26509 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26511 * prj-part.adb (Parse_Single_Project): Set the location of a project
26512 on its defining identifier, rather than on the reserved word "project".
26514 * prj-proc.adb (Expression): Adapt to the fact that default of external
26515 references may be string expressions, not always literal strings.
26516 (Recursive_Process): Set Display_Name equal to Name
26517 when Location is No_Location, that is when there is no actual file.
26518 Get the Display_Name of the project from the source, when it is not a
26520 (Process): Use the Display_Name in error messages
26522 * prj-strt.adb (External_Reference): Allow default to be string
26523 expressions, not only literal strings.
26525 2005-03-29 Vincent Celier <celier@adacore.com>

26536 equivalent type for a remote access-to-subprogram type, go back to the
26537 original RAS entity when displaying an error message, so the casing is
26538 the original source casing.

26547 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26548 subtype if code is being pre-analyzed, to prevent un-expanded
26549 references to protected formals, among others.
26550 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26551 interpretation that can be a call, include the result of the call as a
26552 possible interpretation of the dereference.
26554 * sem_ch5.adb (Process_Bounds): Determine type of range by
26555 pre-analyzing a copy of the original range, and then analyze the range
26556 with the expected type.
26558 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26559 with an overloaded prefix where not all interpretations yield an
26560 access to subprogram, do not rewrite node as a call.
26561 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26562 the node as a call once the context identifies the interpretation of
26563 the prefix whose call yields the context type.
26564 (Valid_Conversion): For the case of a conversion between
26565 local access-to-subprogram types, check subtype conformance using
26566 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26567 detailed error message.

26571 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26572 indicator, indicate that the formal can never be null.
26573 (Process_Formals): If a formal has a non_null indicator, insert the
26574 resulting subtype immediately before the enclosing subprogram decl,
26575 and not at the beginning of the corresponding declarative part, to
26576 prevent access before elaboration (Ada2005).

26699 explanatory error message (including the name of the missing attribute).
26700 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26701 subprogram determines whether a default implementation exists for a
26702 given stream attribute.
26703 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26704 Determine whether to generate a default implementation for each stream
26705 attribute separately, as this depends on the specific attribute.
26707 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26708 limited extension where a stream attribute is missing for a limited
26709 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27310 expression to the type of the object when the object is constant.
27311 Reverse defer_debug_incomplete_list before traversing it, so that trees
27312 are processed in the order at which they were added to the list. This
27313 order is important when using the stabs debug format.
27314 If we are deferring the output of debug information, also defer this
27315 output for a function return type.
27316 When adding fields to a record, prevent emitting debug information
27317 for incomplete records, emit the information only when the record is
27319 (components_to_record): New parameter defer_debug.
27320 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27321 (gnat_to_gnu_field_decl): New function.
27322 (substitution_list, annotate_rep): Call it.
27323 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27324 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27325 No longer update discriminants to not be a COMPONENT_REF.
27326 (copy_alias_set): Strip padding from input type; also handle
27327 unconstrained arrays properly.
27329 * gigi.h (write_record_type_debug_info): New function.
27330 Convert to use ANSI-style prototypes. Remove unused
27331 declarations for emit_stack_check, elab_all_gnat and
27332 set_second_error_entity.
27333 (gnat_to_gnu_field_decl): New decl.
27335 * utils.c (write_record_type_debug_info): New function.
27336 (finish_record_type): Delegate generation of debug information to
27337 write_record_type_debug_info.
27338 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27339 (update_pointer_to): Fix pasto.
27340 (convert) <UNION_TYPE>: Accept slight type variations when
27341 converting to an unchecked union type.
27343 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27344 replace the N_Freeze_Entity with a null statement.
27346 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27347 within a constrained subcomponent of an enclosing record, place the
27348 freeze nodes in the scope stack entry for the enclosing record.
27349 (Undelay_Type): New Subprogram.
27350 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27351 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27352 within records; allow them to have freeze nodes if their base types
27355 * exp_util.adb (Remove_Side_Effects): Properly test for
27356 Expansion_Delayed and handle case when it's inside an
27357 N_Qualified_Expression.
27359 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27360 Comes_From_Generic, to recognize accurately that the parent type in a
27361 derived type declaration can be traced back to a formal type, because
27362 it is one or is derived from one, or because its completion is derived
27364 (Constrain_Component_Type): If component comes from source and has no
27365 explicit constraint, no need to constrain in in a subtype of the
27367 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27368 Minor change to propagate Is_Ada_2005 flag
27370 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27371 Expansion_Delayed is False.
27372 (assoc_to_constructor): Ignore fields that have a
27373 Corresponding_Discriminant.
27374 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27375 function returns "by target", dereference the target pointer using the
27376 type of the actual return value.
27377 <all>: Be prepared for a null gnu_result.
27378 (processed_inline_subprograms): Check flag_really_no_inline
27379 instead of flag_no_inline.
27380 (set_second_error_entity): Remove unused function.
27381 (gnat_to_gnu, case N_Selected_Component): Call
27382 gnat_to_gnu_field_decl.
27383 (assoc_to_constructor): Likewise.
27385 2005-03-15 Robert Dewar <dewar@adacore.com>
27386 Ed Schonberg <schonberg@adacore.com>
27387 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27389 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27390 Must_Be_Byte_Aligned for cases where we do not need to use a
27391 System.Pack_nn unit.
27393 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27395 Needed now that we do some processing for IN parameters as well. This
27396 may well fix some unrelated errors.
27397 (Expand_Call): Handle case of unaligned objects (in particular those
27398 that come from packed arrays).
27399 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27400 renamed entity is an inherited operation, re-expand the call using the
27401 original operation, which is the one to call.
27402 Detect attempt to inline parameterless recursive subprogram.
27403 (Represented_As_Scalar): Fix to work properly with private types
27404 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27405 accurate estimate. Yields True in far fewer cases than before,
27406 improving the quality of code that depends on this test.
27408 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27409 over both visible and private declarations to remove them from tree,
27410 and mark subprograms declared in package as eliminated, to prevent
27411 spurious use in subsequent compilation of generic units in the context.
27413 * exp_util.ads: Minor cleanup in variable names
27415 * sem_eval.ads, sem_eval.adb: Minor reformatting
27416 (Compile_Time_Known_Bounds): New function
27418 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27420 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27421 determining whether an unchecked conversion is needed for the argument
27422 of an initialization call.
27424 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27426 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27427 that appears in the instantiation rather than the internal subtype
27428 generated in the wrapper package, to avoid anomalies in gigi when the
27429 target is derived from a private type whose full view is an access type.
27431 2005-03-15 Robert Dewar <dewar@adacore.com>
27433 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27435 Add documentation to replace the use of this flag
27436 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27439 2005-03-15 Thomas Quinot <quinot@adacore.com>
27441 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27442 here from exp_attr so it can be shared between exp_attr and exp_dist.
27443 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27444 all TSS names, not a subset thereof, and the previous name introduced
27445 an unnecessarily confusion that a distinction might exist between
27446 "OK" TSS names and some "not OK" TSS names.
27448 2005-03-15 Doug Rupp <rupp@adacore.com>
27450 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27453 2005-03-15 Pascal Obry <obry@adacore.com>
27454 Eric Botcazou <ebotcazou@adacore.com>
27458 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27459 when IN_RTS. This is to work around a bootstrap path problem.
27461 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27462 table and pass it to __gnat_install_SEH_handler().
27463 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27465 * lang.opt: Fix specification of -fRTS=.
27467 2005-03-15 Doug Rupp <rupp@adacore.com>
27468 Bernard Banner <banner@adacore.com>
27469 Vincent Celier <celier@adacore.com>
27470 Arnaud Charlet <charlet@adacore.com>
27473 This change works fine when gnatlib is built from the gcc directory,
27474 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27475 is not passed to ada/Makefile.in, so more work is needed by a
27476 Makefile/configure expert.
27478 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27479 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27480 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27482 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27483 Run ranlib on libgccprefix.a
27484 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27485 (ADA_INCLUDE_SRCS): Split Ada packages.
27487 2005-03-15 Robert Dewar <dewar@adacore.com>
27489 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27491 * impunit.adb: Add GNAT.UTF_32
27493 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27495 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27496 now uses GNAT.UTF_32).
27498 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27499 capabilities for categorizing characters using Unicode categories
27501 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27503 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27504 instantiation that has been rewritten as a package body, retrieve spec
27505 to generate proper name for implicit_with_clause.
27506 (Install_Parents): Recognize a parent that is an instantiation but has
27507 been rewritten as a package declaration during analysis.
27509 2005-03-15 Javier Miranda <miranda@adacore.com>
27510 Ed Schonberg <schonberg@adacore.com>
27512 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27513 parameter reported some error we immediately return. This improves the
27514 behaviour of the frontend in case of errors.
27515 (Install_Parent, Remove_Parent): Introduce new flag
27516 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27517 ancestor of a generic child unit, when the child is being instantiated.
27518 (Inline_Instance_Body): If we are compiling the private
27519 part or the body of a child unit, restore the proper visibility of the
27520 parents after compiling the instance body.
27522 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27523 Javier Miranda <miranda@adacore.com>
27526 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27527 of a private type, in which case it is underlying_type that denotes
27528 the proper task. Also modified to use the new entity attribute
27529 that is directly available in the task type and task subtype entities
27530 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27531 arrays when other dimensions than the first are constrained by
27532 discriminants of an enclosing record.
27533 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27534 a combination of indexed and selected components, find ultimate entity
27535 and generate the appropriate reference for it, to suppress spurious
27537 (Note_Possible_Modification): If an entity name has no entity, return.
27538 (Is_Variable): A function call never denotes a variable.
27539 (Requires_Transient_Scope): For record types, recurse only on
27540 components, not on internal subtypes that may have been generated for
27541 constrained components.
27543 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27545 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27546 Eliminated as candidates for resolution. Both efficient, and avoids
27547 anomalies with operators declared in deleted code.
27548 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27549 expansion is disabled (as when compiling a generic) to prevent spurious
27550 warnings on prefixes of selected components.
27552 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27554 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27555 attached to a list before checking whether it appears in the private
27556 declarations of the current package.
27557 (Make_Inequality_Operator): Insert declaration in proper declarative
27558 list rather than just setting the Parent field, so that
27559 Is_Private_Declaration can handle it properly.
27561 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27563 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27564 a renaming a body, check that the renamed subprogram in not intrinsic.
27565 (Find_Direct_Name): If several use_visible entities hide
27566 each other, and the context is a predefined file compiled through
27567 rtsfind, keep only the entity that comes from a predefined file.
27569 2005-03-15 Geert Bosch <bosch@adacore.com>
27571 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27572 long float padding to also cover AMD64 and IA64.
27574 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27576 * s-imgwch.adb: Add with and use of Interfaces.
27577 (Img_Wide_Character): Change type of Val to Unsigned_16.
27578 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27580 2005-03-15 Matthew Gingell <gingell@adacore.com>

27616 procedures in the bug boxes for various GNAT builds.
27618 2005-03-15 Vincent Celier <celier@adacore.com>
27620 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27625 Cyrille Comar <comar@adacore.com>
27626 Sergey Rybin <rybin@adacore.com>
27628 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27629 too specific and long-winded to be appropriate for the GNAT User's
27631 Warn about use of GCC switches not documented in the GNAT User's Guide,
27632 as these may cause generated code to not conform to Ada semantics.
27633 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27634 Add documentation for -gnat95 and -gnat05 switches
27635 Remove paragraph documenting obsolete way to refer to third party

27760 * exp_ch3.ads, exp_ch3.adb: Fix various places where Wide_Wide_String
27761 was not taken into account.
27762 This includes proper initialization with Normalize_Scalars.
27763 (Get_Simple_Init_Val): Major rewrite for initialize scalars and
27764 normalize scalars cases (particularly the latter) to do a better job
27765 of finding invalid representations.
27767 * s-scaval.ads, s-scaval.adb: Add values for zero invalid values
27769 * s-strops.ads, s-strops.adb: Remove string normalize routines, never
27772 * exp_dist.adb: Add support for wide wide character type
27773 (Expand_Receiving_Stubs_Bodies): For a package declaration that has a

27911 value by a warning message.
27912 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted

28054 the formal subprogram.
28055 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28056 which is an unclean use of that field, we set the new field

28075 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28076 mark in function specification, in a context where the formals are
28077 visible and hide outer homographs.
28079 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28080 as the tagged type for the cases of abstract formal subprograms and
28081 renamings of those. Clean up spec comments.

28083 procedure", covering the case of a call to a formal abstract procedure
28084 that has statically tagged operands.
28085 (Check_Dispatching_Call): Check for the case of an actual given by
28086 a tag-indeterminate function call whose type is an ancestor of the
28087 containing call's associated tagged type. This situation can occur

28282 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28283 with expansion disabled. The actual subtype is needed among other
28284 places when the selected component appears in the context of a loop
28285 bound, and denotes a packed array.
28286 (Operator_Check): Always use the first subtype in the
28287 error message, to avoid the appearance of internal base types.
28288 (Transform_Object_Operation): Copy each actual in full
28289 to the parameter associations of the constructed call, rather than
28290 using the shallow copy mechanism of New_Copy_List. This ensures that
28291 the chaining of named associations is done properly.
28292 (Complete_Object_Operation): Rewrite node, rather than
28293 replacing it, so that we can trace back to the original selected
28296 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28297 and calls that use object notation, if the called function is not
28298 declared in a withed unit, place the elaboration constraint on the
28299 unit in the context that makes the function accessible.
28300 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28301 imposes an elaboration constraint between two packages.
28303 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28305 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28306 views of a private type after handling its private dependents, to
28307 maintain proper stack discipline between entry and exit from the

28328 Slight fix to documentation of -gnaty with no parameters
28330 * xr_tabls.ads: Add ??? comment for missing overall comment
28332 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28333 we now use by default.
28335 * xsnames.adb: Adjust end of file test to look for five space followed
28336 by '#' instead of six spaces. The format of xsnames.adb was modified
28337 in the last update.
28339 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28342 * clean.adb: Minor reformatting.

28348 * csets.adb: Eliminate obsolete comment
28350 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28353 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28355 2005-02-09 Sergey Rybin <rybin@adacore.com>
28357 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28358 the difference between compact and incompact layout and add the record
28359 representation clause to the example illustrating different layouts.
28360 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28361 component clauses").
28363 2005-02-09 Florian Villoing <villoing@adacore.com>
28365 * gnat_ugn.texi: Fix typos.
28366 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28368 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28369 in the generated documentation.
28371 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28373 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
28375 Update linker wrapper when linking with non GNU C++.
28377 2005-02-09 Pascal Obry <obry@adacore.com>

28413 * exp_util.ads: Minor correction in comment.
28415 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28417 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28418 since this procedure is now too complex to be worth inlining.

28665 2005-01-03 Olivier Hainque <hainque@adacore.com>
28667 * decl.c (compatible_signatures_p): New function. The intended purpose
28668 is to check if two function signatures for a call-site and a callee are
28669 compatible enough for the call to be valid. The underlying purpose is
28670 to check if a call to a mapped builtin is using the right interface.
28671 The current code actually does not check antyhing - this a placeholder
28672 for future refinements.

28721 variants of the PCS.
28722 Reorganise RPC receiver generation to reduce differences between the
28723 structure of GARLIC and PolyORB RPC receivers.
28724 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
28726 Simplify elaboration code for RCI packages.
28728 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver
28729 generation to reduce differences between the structure of GARLIC and

29090 prefix is generated, if appropriate.
29092 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29093 dereference is rewritten to an explicit one, generate a reference to

29211 used to record an implicit dereference as a read operation on its
29212 prefix when operating under -gnatc. Necessary to avoid spurious
29213 'variable assigned but never read' warnings in that mode.
29214 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29215 is a non-overloaded implicit dereference, call the above subprogram to
29216 ensure proper recording of references.
29218 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29220 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29263 Reformatting to suppress most of the warnings for line too long
29264 Document the new section "Project Search Path:" in the output of
29266 Add gnatmetric section
29268 2004-12-07 Vincent Celier <celier@adacore.com>
29270 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29271 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29272 and -eit to -ept. Added qualifier
29273 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29275 2004-11-27 Andreas Schwab <schwab@suse.de>
29277 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29279 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29281 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29282 internal implementation unit GNAT.Sockets.Thin,
29283 as their usage for sockets is non-portable (using the read and write
29284 functions from the system runtime library is fine on UNIX but won't
29285 work under Windows).
29287 * mingw32.h: Update copyright notice.
29289 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29291 * ada-tree.h: Minor reformatting of previous change to avoid lines
29292 longer than 79 characters.
29294 2004-11-25 Olivier Hainque <hainque@adacore.com>
29296 * tb-gcc.c: GCC infrastructure based implementation of

29310 2004-11-21 Andreas Jaeger <aj@suse.de>
29312 * stylesw.adb: Change Style_Check_Subprogram_Order to
29313 Style_Check_Order_Subprograms.
29315 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29317 * adaint.h, adaint.c
29318 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29320 Add also a cast to kill another warning.
29321 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29322 parameter with the priority class of the parent process instead of
29323 always using the NORMAL_PRIORITY_CLASS.
29324 (__gnat_dup): New function.
29325 (__gnat_dup2): New function.
29326 (__gnat_is_symbolic_link): Enable the effective body of this
29327 function when __APPLE__ is defined.
29329 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29332 2004-11-18 Olivier Hainque <hainque@adacore.com>
29334 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29335 address of which may be used to represent "others" and "all others"
29336 choices in exception tables, instead of the current harcoded
29337 (void *)0 and (void *)1.
29338 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29340 * gigi.h (others_decl, all_others_decl): New decls representing the
29341 new Others_Value and All_Others_Value objects.
29342 (struct attrib): Rename "arg" component as "args", since GCC expects a
29343 list of arguments in there.
29345 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29346 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29349 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29350 others_decl and all_others_decl instead of hardcoded dummy addresses
29351 to represent "others" and "all others" choices, which is cleaner and
29352 more flexible with respect to the possible eh pointer encoding policies.
29354 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29355 (process_attributes): Account for the naming change of the "args"
29356 attribute list entry component.
29358 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29359 cumulating attributes for different entities into a single list.
29360 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29361 attributes for the current entity and propagate first subtype
29362 attributes to other subtypes.
29363 <E_Procedure>: Attribute arguments are attr->args and not
29364 attr->arg any more.
29365 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29366 argument provided, as this is what GCC expects. Use NULL_TREE instead
29369 2004-11-18 Robert Dewar <dewar@adacore.com>
29371 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29372 Minor reformatting througout (including new function specs)
29373 Add ??? comments asking for clarification.
29375 2004-11-18 Thomas Quinot <quinot@adacore.com>
29377 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29378 incomplete duplicate implementation of this subprogram from butil.
29380 2004-11-18 Thomas Quinot <quinot@adacore.com>
29382 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29383 procedures factors the common processing for building an RPC receiver
29384 for an RCI package or an RACW type.
29385 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29386 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29387 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29389 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29391 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29393 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29394 distribution subprogram identifiers that are either subprogram numbers
29396 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29397 string distribution identifiers assigned to a given subprogram.
29398 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29399 (Add_RAS_Dereference_TSS): Add comments.
29400 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29401 is not referenced yet because it will be used by the PolyORB DSA
29403 (Insert_Partition_Check): Remove fossile code.
29404 (First_RCI_Subprogram_Id): Document this constant.
29405 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29407 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29408 replaced with calls to Get_Library_Unit_Name_String. Previously there
29409 were several instances of the same code in different locations in the
29410 compiler; this checkin completes the replacement of all of these
29411 instances with calls to a common subprogram.
29412 Minor reformatting.
29414 * sem_dist.adb: Remove comment noting that RPC receiver generation
29415 should be disabled for RACWs that implement RASs.
29416 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29418 * sem_util.ads, sem_util.adb (Has_Stream): New function
29419 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29420 qualified name of a library unit into the name buffer.
29421 (Note_Possible_Modification): Generate a reference only
29422 if the context comes from source.
29424 * snames.ads (PCS_Names): New subtype corresponding to names of
29425 supported implementations of the Partition Communication Subsystem
29426 (PCS) (i.e. the runtime library support modules for the distributed
29429 2004-11-18 Robert Dewar <dewar@adacore.com>
29430 Ed Schonberg <schonberg@adacore.com>
29432 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29433 (Has_Rep_Pragma): New function
29434 (Has_Attribute_Definition_Clause): New function
29435 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29436 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29438 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29440 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29441 (Expand_Pragma_Psect_Object): New procedure
29442 These procedures contain the revised and cleaned up processing for
29443 these two pragmas. This processing was formerly in Sem_Prag, but
29444 is more appropriately moved here. The cleanup involves making sure
29445 that the pragmas are properly attached to the tree, and that no
29446 nodes are improperly shared.
29448 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29449 pragmas to Exp_Prag, which is more appropriate.
29450 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29451 check for duplicates Remove use of Is_Psected flag, no longer needed.
29452 Use new Make_String_Literal function with string.
29454 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29455 that are functions return universal values, that have to be converted
29456 to the context type.
29457 Use new Make_String_Literal function with string.
29458 (Get_Stream_Convert_Pragma): New function, replaces the use of
29459 Get_Rep_Pragma, which had to be kludged to work in this case.
29461 * freeze.adb: Use new Has_Rep_Pragma function
29463 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29464 function with string.
29465 Use new Has_Rep_Pragma function.
29467 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29470 2004-11-18 Robert Dewar <dewar@adacore.com>
29472 * errout.ads, errout.adb: (First_Sloc): New function
29474 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29475 check (-gnatyx) instead of being included as a redundant construct
29478 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29479 Style_Check_Order_Subprograms.
29481 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29482 stylesw.adb: Add Style_Check_Xtra_Parens
29484 * usage.adb: Add line for -gnatyx (check extra parens)
29486 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29488 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29489 Robert Dewar <dewar@adacore.com>
29491 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29492 discriminant of a constrained subtype, analyze the copy of the
29493 corresponding constraint, because in some cases it may be only
29494 partially analyzed.
29495 Removes long-lived ??? comments.
29497 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29498 handled controlled or secondary-stack expressions within the
29499 iteration_scheme of a loop.
29501 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29502 bounds that may contain functions calls, to prevent memory leaks when
29503 the bound contains a call to a function that uses the secondary stack.
29504 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29505 generate temporaries for loop bounds that might contain function calls
29506 that require secondary stack and/or finalization actions.
29508 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29509 selected component and the selector is overloadable (not just a
29510 function) treat as function call, Analyze_Call will disambiguate if
29512 (Analyze_Selected_Component): Do not generate an actual subtype for the
29513 selected component if expansion is disabled. The actual subtype is only
29514 needed for constraint checks.
29515 (Analyze_Allocator): If restriction No_Streams is set, then do
29516 not permit objects to be declared of a stream type, or of a
29517 composite type containing a stream.
29519 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29520 No_Streams no longer prohibits with'ing this package.
29522 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29523 discriminants, but the parent base has unknown discriminants, there is
29524 no discriminant constraint to inherit. Such a discrepancy can arise
29525 when the actual for a formal type with unknown discriminants is a
29526 similar private type whose full view has discriminants.
29527 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29528 do not permit objects to be declared of a stream type, or of a
29529 composite type containing a stream.
29531 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29533 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29534 protected operations.
29536 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29537 generated name, it complicates decoding in gdb and hinders debugging
29538 of protected operations.
29539 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29540 flag for the protected entry barrier function.
29541 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29542 flag for the protected entry function.

29546 * expect.c: Define __unix__ when __APPLE__ is defined.
29548 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29549 Darwin-specific section.
29551 * lang-specs.h: Change the placement of the %1 marker.
29552 Works around the fact that gcc adds -fPIC by default under Darwin.
29554 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29556 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29557 type of the object with the packed array type, set the Analyzed flag
29558 on the object if it is an entity or simple indexed component, to avoid
29559 spurious type errors.
29561 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29563 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29564 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29565 separate line from the version message.
29567 2004-11-18 Ed Falis <falis@adacore.com>
29569 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29571 (init_float): Eliminate initialization of floating point status for
29572 AE653. The instructions have no effect for vThreads.
29574 2004-11-18 Vincent Celier <celier@adacore.com>
29576 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29577 gnatbind is invoked with -shared.
29579 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29581 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29582 for Detect_Blocking which is redundant with the check done within the
29583 procedure Protected_Single_Entry_Call.
29584 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29585 Detect_Blocking which is redundant with the check done within the
29586 procedure Protected_Single_Entry_Call.
29588 2004-11-18 Vincent Celier <celier@adacore.com>
29590 * makegpr.adb (Compile): Put the compiling switches (in package
29591 Compiler and on the command line) immediately after "-c", instead of
29592 at the end of the command line invocation of the compiler, when
29593 compiling a non-Ada file.
29594 (Build_Global_Archive): When there is no need to rebuild the archive,
29595 set Global_Archive_Exists, so that the archive is passed to the linker
29598 2004-11-18 Robert Dewar <dewar@adacore.com>
29599 Sergey Rybin <rybin@adacore.com>
29602 Remove extra paren check from list of checks for redundant constructs
29603 Add documentation of new -gnatyx style check (check extra parens)
29604 Remove paragraph about gnatelim debug options.
29606 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29607 objects rather than forbidding dependencies on the package Ada.Streams.
29609 * sinfo.ads: Add ??? note that we should document pragmas passed to
29612 * g-expect.ads: Fix a few typos in the comments.
29614 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29616 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29619 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29621 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29623 2004-11-07 Andreas Schwab <schwab@suse.de>
29625 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29627 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29630 * Makefile.in (darwin): Set soext to .dylib.
29632 2004-10-26 Vincent Celier <celier@gnat.com>
29633 Thomas Quinot <quinot@act-europe.fr>
29635 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29636 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29637 there is no use of GNAT.Sockets.Constants.
29638 Remove remaining pragma Import for C_Write
29639 Remove C_Read and C_Write from internal implementation unit
29640 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29641 the read and write functions from the system runtime library is fine
29642 on UNIX but won't work under Windows).
29644 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29645 (Check_Selector): Use C_Recv instead of C_Read.
29646 Selectors are the GNAT.Sockets abstraction to perform a select()
29647 call on a set of descriptors. To allow abortion of an ongoing
29648 select operation, some data is written to a dedicated socket that
29649 is always monitored.
29650 Under Windows, the write and read library functions cannot operate
29651 on sockets, so we need to use send and recv instead, which is portable
29652 across all supported platforms.
29654 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29655 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29656 (using the read and write functions from the system runtime library is
29657 fine on UNIX but won't work under Windows).
29659 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29661 * mlib-tgt-darwin.adb: New file.
29663 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29664 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29665 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29666 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29669 * Makefile.in: Add support for building shared libraries under Darwin.
29670 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29671 the low level EH init subprogram to be called from __gnat_initialize.
29673 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29674 indicates which options to pass to the archive indexer.
29676 * mlib-utl.adb: Add support for calling ranlib with additional
29677 options. This is needed for instance under Mac OS X.
29678 (Ranlib_Options): New global variable, used to store the potential
29679 options to pass to ranlib.
29680 (Ar): Use Ranlib_Options when spawning ranlib.
29681 (Initialize): Set the value of ranlib option.
29683 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29685 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29686 instead of 8K, to reflect the real potential needs for stack-checking
29689 2004-10-26 Pascal Obry <obry@gnat.com>
29691 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29693 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29694 Windows only the initial thread stack size can be set so it is good to
29695 start we a low stack size.
29696 The OS will adjust the size as needed.
29698 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29699 Nicolas Setton <setton@act-europe.fr>
29701 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29702 "__unix__" instead of "unix".
29703 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29704 sections were just mistakenly ignored. The former is
29705 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29706 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29707 of hpux. This prevents an unwanted definition of the symbol
29708 convert_addresses in adaint.o.
29710 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29712 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29713 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29715 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29717 * a-filico.ads, a-filico.adb: fix incorrect header.
29719 2004-10-26 Javier Miranda <miranda@gnat.com>
29721 * a-ststio.ads: Fix typo in identifier
29723 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29725 * sem_ch4.adb: Minor reformatting.
29727 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29729 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29730 enabled, check the result of unary and binary operations when the
29731 expression is the right-hand side of an assignment.
29733 2004-10-26 Vincent Celier <celier@gnat.com>
29735 * clean.adb (Delete): Do not output warnings when in quiet output and
29736 not in verbose mode.
29737 (Force_Deletions): New Boolean flag, defaulted to False
29738 (Delete): Only delete a file if it is writable, and when
29739 Force_Deletions is True.
29740 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29741 (Usage): Line for new switch -f
29742 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29745 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29747 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29748 JM type only if its size matches that of the wrapper. When a size is
29749 prescribed and the field is not aliased, remove the wrapper of a JM
29750 type only if the size is not greater than that of the packed array.
29751 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29754 2004-10-26 Geert Bosch <bosch@gnat.com>
29756 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29757 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29758 (Pred): Implement in terms of Succ.
29760 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29762 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29763 unchecked conversion is safe for in-place use if the expression of the
29764 conversion is safe.
29765 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29766 be expandable in place even if the aggregate does not come from source.
29767 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29768 designated object of an allocator in place, rather than building it
29769 first on the stack. The previous scheme forces a full copy of the array,
29770 and may be altogether unsusable if the size of the array is too large
29771 for stack allocation.
29773 2004-10-26 Robert Dewar <dewar@gnat.com>
29775 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29776 compares if the component is atomic.
29778 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29779 array assignment if the component type is atomic.
29781 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29782 Eric Botcazou <ebotcazou@act-europe.fr>
29784 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29785 is aliased and is a by_reference type, do not pass by copy.
29786 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29787 detect whether the call is in the right side of an assignment or
29788 the expression of an object declaration. Recurse on component
29789 association within aggregates.
29790 Call it in the condition that determines whether the temporary is
29791 necessary for correct stack-checking.
29793 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29795 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29796 RACW_Type, used in the PolyORB version.
29797 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29798 version and the GARLIC version.
29800 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29801 Rename RCI_Info to RCI_Locator for better consistency between the
29802 GARLIC and PolyORB versions of the distributed systems annex.
29803 (DSA_Implementation_Name): This enumeration lists the possible
29804 implementations of the Partition Communication Subsystem for the
29805 Distributed Systems Annex (DSA). The three available implementations
29806 are the dummy stub implementation (No_DSA), and two versions based on
29807 two different distribution runtime libraries: GARLIC and PolyORB. Both
29808 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29810 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29813 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29814 between the GARLIC and PolyORB versions of the distributed systems
29816 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29818 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29820 * gnat1drv.adb: Suppress calling the back end when
29821 Frontend_Layout_On_Target is true.
29823 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29825 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29826 Set_Read_Only): New subprograms.
29827 These new routines allow the user to set or unset the Owner execute
29828 and Owner write permission flags on a file.
29830 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29831 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29833 2004-10-26 Matthew Gingell <gingell@gnat.com>
29835 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29837 2004-10-26 Pascal Obry <obry@gnat.com>
29839 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29840 memory before the faulting page we properly test the process read
29841 access for this address using appropriate Win32 routine.
29842 (HPUX sections): guard with "__hpux__" instead of "hpux".
29844 2004-10-26 Robert Dewar <dewar@gnat.com>
29846 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29847 entry parameter if pragma Unreferenced set, since we do not properly
29848 handle the case of multiple parameters.
29850 2004-10-26 Vincent Celier <celier@gnat.com>
29852 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29853 (Ada_Objects_Path.Add): For a library project, add to the object path
29854 the library directory only if there is no object directory or if the
29855 library directory contains ALI files.
29856 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29858 2004-10-26 Vincent Celier <celier@gnat.com>
29860 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29861 extension of library projects.
29863 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29864 path defaults to ".:<prefix>/lib/gnat".
29865 (Parse): For an extending all project, allow direct import of a project
29866 that is virtually extended.
29868 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29869 the specified name is directly imported, return its ID. Otherwise, if
29870 an extension of this project is imported, return the ID of the
29873 2004-10-26 Robert Dewar <dewar@gnat.com>
29875 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29876 (Sub3): New procedure, used by Scaled_Divide
29877 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29878 correct more than one instance of failure to propagate carries
29880 (Double_Divide): Handle overflow case of largest negative number
29881 divided by minus one.
29883 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29884 the case of a quotient value out of range.
29887 2004-10-26 Robert Dewar <dewar@gnat.com>
29889 * s-bitops.adb (Bit_Eq): Remove redundant check.
29891 * s-bitops.ads: Minor comment updates
29892 Change some occurrences of Address to System.Address
29894 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29896 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29898 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29899 accessibility check to prefix that is a protected operation.
29901 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29903 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29904 empty, post message on stub.
29906 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29907 Javier Miranda <miranda@gnat.com>
29909 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29910 current instance appears within a unit that is directly in the context
29912 Used to determine whether the body of the instance should be analyzed
29913 immediately after its spec, to make its subprogram bodies available
29914 for front-end inlining.
29915 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29916 constraint is not allowed on the component type (AARM 12.5.3(3))
29918 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29920 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29921 'Storage_Pool): enhance, document & limit detection of non-sharable
29924 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29926 * s-pooglo.ads: Add more documentation now that this pool is properly
29929 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29931 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29932 or protected type with discriminants, do not constrain the
29933 corresponding record type if the subtype declaration has no
29934 discriminant constraints. This can be the case in source code, or in
29935 the subtype declaration created to rename an actual type within an
29938 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29940 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29941 different kind of stub (possibly wrong name for file), do not check
29943 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29944 includes call to some function that returns an unconstrained type, do
29947 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29949 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29950 appear in the code for the main unit. Dependencies among units in the
29951 context of the main unit are established when those other units are
29952 compiled. Otherwise spurious elaboration constraints can generate
29953 incorrect elaboration circularities.
29955 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29956 Ed Schonberg <schonberg@gnat.com>
29958 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29959 subprogram is called with a parameter that is not an object name. This
29960 situation arises for some cases of illegal code, which is diagnosed
29961 later, and in this case it is wrong to call Is_Aliased, as that might
29962 cause a compiler crash.
29963 (Explain_Limited_Type): Refine previous fix to include
29964 inherited components of derived types, to provide complete information.
29966 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29967 is the prival for a protected object.
29968 It is necessary to mark this entity as a variable, in addition to
29969 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29970 modified to avoid checking the Aliased flag on entities that are not
29971 objects. (Checking that flag for non-objects is erroneous and could
29972 lead to a compiler crash).
29974 2004-10-26 Robert Dewar <dewar@gnat.com>
29976 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29977 X_Frac = 0.5, then we know that the number X must be positive.
29978 (Succ): Remove the same redundant test, and also fix the primary test
29979 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29981 (Decompose): Add fuller comments to spec
29983 2004-10-26 Pascal Obry <obry@gnat.com>
29985 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29986 validity (process must have read access). Set to 0 in all other cases.
29987 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29988 violation on Win32.
29989 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29990 segmentation violation.
29992 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29994 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
29995 whose type is a constructed subtype of an aliased object with an
29996 unconstrained nominal subtype, convert the actual to the constructed
29997 subtype before taking its address.
29999 2004-10-26 Vincent Celier <celier@gnat.com>
30001 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30002 (Is_Path_Name_Case_Sensitive): New function
30004 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30005 (Base_Name, Simple_Name, Current_Directory, Compose,
30006 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30009 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30010 Vasiliy Fofanov <fofanov@act-europe.fr>
30011 Vincent Celier <celier@gnat.com>
30013 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30014 "memory management issues" section and document some of the useful
30015 memory pools provided as part of the GNAT library.
30016 Remove "virtual" from declaration of A::method2 in
30017 the simple example of Ada/C++ mixed system.
30018 Library Projects may be virtually extended: their virtual extensions
30019 are not Library Projects.
30020 Added section on extending project hierarchies.
30022 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30024 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30026 (__gnat_portable_spawn): Remove const.
30028 * mingw32.h (MAXPATHLEN): Check for previous definition.
30030 2004-10-17 Matthias Klose <doko@debian.org>
30032 * gnatvsn.ads: Set gnat library version to 4.0.
30034 2004-10-05 Vincent Celier <celier@gnat.com>
30036 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30038 2004-10-04 Laurent Guerby <laurent@guerby.net>
30041 * Makefile.in: Define and use RANLIB_FLAGS.
30043 2004-10-04 Pascal Obry <obry@gnat.com>
30045 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30046 other x86 platforms).
30048 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30050 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30051 in general and triggers stack alignment adjustment for thread entry
30052 points on targets where this is necessary.
30054 2004-10-04 Bernard Banner <banner@gnat.com>
30057 * Makefile.in: Add section for powerpc linux
30058 Add variant i-vxwork-x86.ads
30060 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30062 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30064 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30065 table registration calls when need be. Ensures no reference to the crt
30066 ctors symbol are issued in the SJLJ case, which avoids possible
30067 undefined symbol errors in the case of modules to be statically linked
30070 2004-10-04 Javier Miranda <miranda@gnat.com>
30072 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30073 in-line the code corresponding to subprogram Analyze_Actuals. In
30074 addition, analyze the actuals only in case of subprogram call.
30076 2004-10-04 Ed Falis <falis@gnat.com>
30078 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30080 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30082 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30083 in the documentation.
30085 2004-10-04 Robert Dewar <dewar@gnat.com>
30087 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30089 (Analyze_Block_Statement): Add circuitry to detect following dead code
30090 (Check_Unreachable_Code): Handle case of block exit
30092 2004-10-04 Robert Dewar <dewar@gnat.com>
30094 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30095 (XMatchD): Avoid warning for Logic_Error call
30097 2004-10-04 Robert Dewar <dewar@gnat.com>
30099 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30100 consider expressions buried within a procedure actual to be an actual.
30101 This caused some blowups with uses of packed slices within a procedure
30104 2004-10-04 Robert Dewar <dewar@gnat.com>
30106 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30107 longer need to be initialized to zero.
30108 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30109 initialized to zero.
30111 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30112 considered valid, even if the representation is modular. That's correct
30113 now that we no longer initialize packed modular arrays to zero.
30115 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30116 suffixes. These are now documented as the only cases in which the
30117 debugger ignores outer records.
30118 Previously, the spec allowed arbitrary suffixes for this purpose.
30119 Change name of LJM to JM for packed array pad records
30120 Create separate section on packed array handling, and add a whole new
30121 set of comments to this section describing the situation with packed
30122 modular types and justification requirements depending on endianness.
30124 2004-10-04 Robert Dewar <dewar@gnat.com>
30126 * a-except.adb: Add a comment for last change

30137 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30139 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30140 Inline_Always when in Configurable_Run_Time mode.
30142 * sem_prag.adb (Process_Convention): If entity is an inherited
30143 subprogram, apply convention to parent subprogram if in same scope.
30144 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30145 when in Configurable_Run_Time mode.
30147 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30149 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30150 class_wide type after component list has been inherited.
30152 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30154 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30155 Denotes_Previous_Actual, to handle properly the case of a private
30156 actual that is also the component type of a subsequent array actual.
30157 The visibility status of the first actual is not affected when the
30158 second is installed.
30159 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30160 make fully recursive the treatment of formals of packages declared
30162 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30163 the above on exit from an instantiation.
30164 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30165 current instantiation which is now complete.
30166 (Analyze_Package_Instantiation): No instantiated body is needed if the
30167 main unit is generic. Efficient, and avoid anomalies when a instance
30168 appears in a package accessed through rtsfind.
30170 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30172 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30173 do not generate a declaration for a temporary if the call is part of a
30174 library-level instantiation.
30176 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30178 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30179 searching for a limited component to flag.
30181 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30182 expansion of Input, to account for the fact that the implicit call
30183 generated by the attribute reference must freeze the user-defined
30184 stream subprogram. This is only relevant to 'Input, because it can
30185 appear in an object declaration, prior to the body of the subprogram.
30187 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30188 expansion can proceed and further errors uncovered.
30189 (Minor clean up): Fix cases of using | instead of \ for continuation
30192 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30201 specified alignment before validating size.
30202 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30203 stripped-down declaration for the type of the inner field when making
30206 * utils.c (finish_record_type): Do not compute the size in units
30207 incrementally. Instead compute it once for the rep clause case.
30208 Use gcc_assert and gcc_unreachable.
30210 2004-10-04 Vincent Celier <celier@gnat.com>
30212 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30214 (Is_Valid_Path_Name): Take '/' as a directory separator.
30216 2004-10-04 Vincent Celier <celier@gnat.com>
30218 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30219 (Extended_Project) only if Extended_Project is defined, to avoid
30221 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30223 (Parse_Single_Project): Ditto.
30225 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30226 Add_To_Project_Path for virtual projects.
30228 2004-10-04 Vincent Celier <celier@gnat.com>
30230 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30231 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,

30233 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30234 parameter Options_2.
30236 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30237 Build_Dynamic_Library with an empty Options_2.
30239 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30242 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30243 directory separator, if any.
30244 (Gprmake): Do not allow mains on the command line for library projects.
30245 Do not attempt to link when the project is a library project.
30246 (Library_Opts): New table to store Library_Options.
30247 (Build_Library): If Library_Options is specified, pass these options
30248 when building a shared library.
30250 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30252 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30253 the end of this procedure now that the unlock operation was inserted
30256 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>

30259 corresponding to the Preallocated_Stacks flags in System.
30260 (Get_Target_Parameters): Including the processing for
30261 Preallocated_Stacks.
30263 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,

30273 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30274 used to signal whether the compiler creates the required stacks and
30275 descriptors for the different tasks (when True) or it is done by the
30276 underlying operating system at run time (when False).
30277 It is initially set to False in all targets.
30279 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30280 if it is supported by the target.
30281 (Make_Task_Create_Call): Pass the stack address if it has been
30282 previously created. Otherwise pass a Null_Address.
30284 * snames.adb: Add _stack.
30286 * snames.ads: Add Name_uStack. Required to allow the expander to
30287 statically allocated task stacks.
30289 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30290 Stack_Address argument.
30291 Check that its value is equal to Null_Address because this target does
30292 not support the static stack allocation.
30294 2004-10-04 Thomas Quinot <quinot@act-europe.fr>

30301 * exp_dist.adb: Split declaration of asynchronous flag out of
30302 Add_RACW_Read_Attribute.
30303 Minor reformatting for better alignment with PolyORB version.
30304 Store the entity for the asynchronous flag of an RACW, rather than the
30305 expression, in the asynchronous flags table. This will allow this flag
30306 to be used in other subprograms beside Add_RACW_Read_Attribute.

30315 sockets constant MSG_NOSIGNAL (Linux-specific).
30316 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30317 all Send operations.
30318 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30319 from trigerring SIGPIPE.
30320 Rename components to avoid clash with Ada 2005 possible reserved

30335 Change "pragma inline" to "pragma Inline" in information and error
30337 Minor reformatting.
30339 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30340 right way of doing things after all.
30341 (Freeze_Entity): For object, set Is_Public for imported entities
30342 unless there is an address clause present.
30344 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30346 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30347 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30348 ensures proper handling of types with rep clauses, which might have
30349 their TYPE_SIZE set already.
30351 2004-09-21 Robert Dewar <dewar@gnat.com>
30353 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30354 packed array types in both little- and big-endian cases. This change
30355 ensures that we no longer count on the unused bits being initialized
30356 for such types (and in particular ensures that equality testing will
30357 only read the relevant bits).
30358 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30359 These changes mean that we no longer need to initialize small packed
30361 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30362 optimization to an LJM field as to its parent field.
30364 * ada-tree.h, trans.c, utils.c, utils2.c:

30367 2004-09-20 Jan Hubicka <jh@suse.cz>
30369 * utils.c (gnat_finalize): Remove.

30371 do not lower the nested functions.
30373 2004-09-20 Robert Dewar <dewar@gnat.com>

30406 an existing directory.
30407 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30408 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30409 Convert the result to File_Size.
30411 * prj.ads: (Project_Error): New exception
30413 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30414 Prj.Com, not from Osint.
30415 (Attrs, Package_Attributes): Tables moved to private part of spec
30416 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30418 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30419 Prj.Project_Error after call to Fail.
30420 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30421 Fail. Check that package name is not already in use.
30423 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30424 used by tools, not only by the project manager, and to indicate that
30425 exception Prj.Prj_Error may be raised in case of problem.
30426 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30428 (Attrs, Package_Attributes): Table instantiations moved from the body to
30429 the private part to be accessible from Prj.Attr.PM body.
30431 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30432 from new package Prj.Attr.PM.
30433 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30436 * Makefile.in: Add prj-attr-pm.o to gnatmake object list

30484 pragmas recognized by GNAT.
30486 * gnat_rm.texi: Document pragma Detect_Blocking.
30488 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30489 raise Program_Error if called from a protected operation.
30491 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30492 the protected action nesting level.
30493 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30494 protected action nesting level.
30495 (Unlock): When pragma Detect_Blocking is active decrease the protected
30496 action nesting level.
30498 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30499 Protected_Action_Nesting.
30501 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30502 Common_ATCB record. It contains the dynamic level of protected action
30503 nesting for each task. It is needed for checking whether potentially
30504 blocking operations are called from protected operations.
30505 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30506 Detect_Blocking is active or not in the partition.
30508 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30509 raise Program_Error if called from a protected operation.

30522 Program_Error if called from a protected operation, and increase the
30523 protected action nesting level.

30536 active, raise Program_Error if called from a protected operation.
30537 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
30538 protected action nesting level.
30540 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30541 insertion of the statement raising Program_Error. The run time
30542 contains the required machinery for handling that.
30544 * sem_util.ads: Change comment associated to procedure
30545 Check_Potentially_Blocking_Operation.
30546 This procedure does not insert a call for raising the exception because
30547 that is currently done by the run time.
30549 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30551 * init.c: Add the global variable __gl_detect_blocking that indicates
30552 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30553 making the pragma available at run time.
30554 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30556 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30557 pragma Detect_Blocking is active.
30559 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30561 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30562 DB is found in the ali file. Any unit compiled with pragma
30563 Detect_Blocking active forces its effect in the whole partition.
30565 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30566 Detect_Blocking is active and delay is called from a protected
30569 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30570 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30571 Detect_Blocking is active (0 otherwise).
30572 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30573 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30576 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30578 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30579 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30582 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30583 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30584 Update API in placeholder implemetation of s-parint to reflect changes
30585 in distribution runtime library.
30587 * sem_ch3.adb (Expand_Derived_Record): Rename to
30588 Expand_Record_Extension.
30590 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30591 primitive operations of potentially distributed object types that have
30592 non-controlling anonymous access formals.
30594 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30596 New implementation of expansion for remote access-to-subprogram types,
30597 based on the RACW infrastructure.
30598 This version of sem_dist is compatible with PolyORB/DSA as well as
30601 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30602 Asynchrronous that applies to a remote access-to-subprogram type, mark
30603 the underlying RACW type as asynchronous.
30605 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30606 __gnat_using_gnu_linker to 1.
30608 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30609 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30610 GNAT.Perfect_Hash_Generators, and remove the empty

30615 * exp_ch3.adb (Expand_Derived_Record): Rename to
30616 Expand_Record_Extension.
30617 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30618 a component declaration must remain attached at that point in the
30619 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30620 It is therefore necessary to take a copy of the expression when building
30621 the corresponding assignment statement in the init proc.
30622 As a side effect, in the case of a derived record type, we now see the
30623 original expression, without any rewriting that could have occurred
30624 during expansion of the ancestor type's init proc, and we do not need
30625 to go back to Original_Node.
30627 * exp_ch3.ads (Expand_Derived_Record): Rename to
30628 Expand_Record_Extension.
30630 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30631 Returns the RACW type used to implement a remote access-to-subprogram
30633 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30634 New subprograms. Used to create a proxy tagged object for a remote
30635 subprogram. The proxy object is used as the designated object
30636 for RAS values on the same partition (unless All_Calls_Remote applies).
30637 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30638 System.Partition_Interface.Get_Unique_Remote_Pointer.
30639 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30640 Renamed from Add_RAS_*_Attribute.
30641 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30643 New implementation of expansion for remote access-to-subprogram types,
30644 based on the RACW infrastructure.
30646 * exp_dist.ads (Copy_Specification): Update comment to note that this
30647 function can copy the specification from either a subprogram
30648 specification or an access-to-subprogram type definition.
30650 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30652 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30653 in an instance, between an explicit subprogram an one inherited from a
30654 type derived from an actual.
30656 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30657 add a polling call if the subprogram is to be inlined by the back-end,
30658 to avoid repeated calls with multiple inlinings.
30660 * checks.adb (Apply_Alignment_Check): If the expression in the address
30661 clause is a call whose name is not a static entity (e.g. a dispatching
30662 call), treat as dynamic.
30664 2004-09-09 Robert Dewar <dewar@gnat.com>
30666 * g-trasym.ads: Minor reformatting
30668 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30674 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
30677 2004-09-09 Pascal Obry <obry@gnat.com>
30679 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30680 enable map file generation. Add the right option to generate the map
30681 file if Map_File is set to True.
30683 * gnatdll.adb (Gen_Map_File): New variable.
30684 (Syntax): Add info about new -m (Map_File) option.
30685 (Parse_Command_Line): Add support for -m option.
30686 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

30708 version of the language is used to compile the run time.
30710 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
30712 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30713 of variable length temporaries for function return now that the
30714 back-end and gigi support it.

34921 complete assignment subtree which is now unnecessary, as the expansion
34922 of inlined call has been improved to preserve a consistent assignment
34923 tree. Note_Possible_Modification must be called only
34924 after checks have been applied, or else unnecessary checks will

35148 (Set_Actual_Subtypes): Generate null-excluding subtype if the
35149 null-excluding part was present; it is not required to be done here in
35150 case of anonymous access types.
35151 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
35154 * sem_res.adb (Resolve_Actuals): Carry out some static check
35155 (Resolve_Null): Allow null in anonymous access
35157 * sinfo.adb: New subprogram Null_Exclusion_Present
35158 All_Present and Constant_Present available on access_definition nodes
35160 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
35161 object_declaration, derived_type_definition, component_definition,
35162 discriminant_specification, access_to_object_definition,
35163 access_function_definition, allocator, access_procedure_definition,
35164 access_definition, parameter_specification, All_Present and
35165 Constant_Present flags available on access_definition nodes.

35181 * sem_ch12.adb: Add comment for previous change
35183 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35185 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35186 executable name when not initialized. Otherwise, use its current value.
35188 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35189 initialize it to another executable name than the current one. This
35190 allows to configure paths for an executable name (gnatmake) different
35191 from the current one (gnatdist).
35193 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35195 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35196 current unit cannot be inlined if it appears in the body of a withed
35197 unit, to avoid order of elaboration problems in gigi.
35199 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35200 information for protected (wrapper) operation as well, to simplify gdb
35203 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35204 protected body, indicate that the entity for the generated spec comes
35205 from source, to ensure that references are properly generated for it.
35206 (Build_Body_To_Inline): Do not inline a function that returns a
35209 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35210 apply convention to homonyms that are declared explicitly.
35212 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35213 that renames an equality operator and the operands are overloaded,
35214 resolve them with the declared formal types, before rewriting as an
35217 2004-03-29 GNAT Script <nobody@gnat.com>
35219 * Make-lang.in: Makefile automatically updated
35221 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35223 * memtrack.adb: Log realloc calls, which are treated as free followed
35226 2004-03-25 Vincent Celier <celier@gnat.com>
35228 * prj-makr.adb (Process_Directories): Detect when a file contains
35229 several units. Do not include such files in the config pragmas or

35238 resolve links when computing the display names.
35240 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35242 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35243 attribute reference does not denote a subtype, it can be any
35244 expression that has a classwide type, potentially after an implicit
35245 dereference. In particular, the prefix can be a view conversion for
35246 a classwide type (for which Is_Object_Reference holds), but it can
35247 also be a value conversion for an access-to-classwide type. In the
35248 latter case, there is an implicit dereference, and the original node
35249 for the prefix does not verify Is_Object_Reference.
35251 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35252 conversion of a discriminant-dependent component of a mutable object
35255 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35257 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35258 inherited, has convention C, and has unconstrained array parameters,
35259 place the corresponding warning on the derived type declaration rather
35260 than the original subprogram.
35262 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35263 indication on renaming declaration, if formal has a box and actual
35266 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35267 determine whether to generate an implicit or explicit reference to
35268 the renamed entity.
35270 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35271 subprogram renaming comes from a defaulted formal subprogram in an
35274 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35276 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35277 value expressions to ensure that calls within a component definition
35278 will be checked (since those are evaluated during the record type's
35281 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35283 * s-tpobop.adb: Code clean up:
35284 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35300 * ali.ads: Fix Comment about Dynamic_Elab.
35302 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
35303 Has_RACW, Is_Generic, etc.)
35304 (Output_Object, Gnatls): Take into account ALI files not attached to
35307 2004-03-22 Vincent Celier <celier@gnat.com>
35309 * gprep.adb: Change all String_Access to Name_Id
35310 (Is_ASCII_Letter): new function
35311 (Double_File_Name_Buffer): New procedure
35312 (Preprocess_Infile_Name): New procedure

35322 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
35324 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35325 case when the source contains only comments.
35327 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35329 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35330 declaration for a child subprogram body that acts as a spec, indicate
35331 that the entity in the declaration needs debugging information.
35333 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35334 full view if the subtype is created for a constrained record component;
35335 gigi has enough information to construct the record, and there is no
35336 place in the tree for the declaration.
35338 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35339 serial number for the dummy body that is built for analysis, to avoid
35340 inconsistencies in the generation of internal names when compiling
35343 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35345 * sem_util.adb (Is_Object_Reference): A view conversion denotes an

35370 * gnat_ug.texi: Add info directory category and entry.
35371 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35372 gnat_ug_wnt.texi: Regenerate.
35374 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35376 * ada-tree.h: Update copyright notice.
35377 Minor reformatting.
35379 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35381 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35382 as regular exception objects and not as mere integers representing the
35383 condition code. The latter approach required some dynamics to mask off
35384 severity bits, which did not fit well into the GCC table based model.
35385 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35386 exception data objects. We don't it and it would conflict with the other
35387 external symbol we have to generate for such exceptions.
35389 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35390 the special code for VMS exceptions, since these are now represented
35391 as regular exceptions objects.
35393 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35395 * decl.c (debug_no_type_hash): Remove.

35397 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35399 2004-03-19 Laurent Guerby <laurent@guerby.net>
35401 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35402 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35404 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35406 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35407 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35408 (TYPE_RM_SIZE_INT): Directly use type.values.
35409 (TREE_LOOP_ID): Clean up check.
35410 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35411 TYPE_VALUES, not TYPE_FIELDS.
35412 * trans.c (convert_with_check): Delay access of bounds of basetype
35413 until sure is numeric.

35421 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35422 Specific.Set instead of direct call to e.g pthread_setspecific.
35424 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35426 * adaint.c: Update comments.
35428 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35429 GNATLIB_SHARED for FreeBSD.
35431 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35433 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35434 When needed (stack checking) the stack size is retrieved
35435 from the VxWorks kernel.
35437 * Makefile.in: Flag -nostdinc is required when building the run time
35438 for avoiding looking for files in the base compiler.
35439 Add the VxWorks specific version of the package body for
35440 System.Stack_checking.Operations (5zstchop.adb).
35442 * Make-lang.in: Add the object file for
35443 System.Stack_Checking.Operations.
35445 * Makefile.rtl: Add object file for the package
35446 System.Stack_Checking.Operations.
35448 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35450 * s-stache.ads, s-stache.adb: Move the operations related to stack
35451 checking from this package to package System.Stack_Checking.Operations.
35452 This way, stack checking operations are only linked in the final
35453 executable when using the -fstack-check flag.
35455 2004-03-18 Doug Rupp <rupp@gnat.com>
35457 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
35460 * 5qsystem.ads, 5xcrtl.ads: New files.

35466 * prj-env.adb (Source_Paths, Object_Paths): New tables.
35467 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35468 the procedures Add_To_Path_File.
35469 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35470 making sure that each directory is present only once and, for object
35471 dirs, when a directory already present is added, the duplicate is
35472 removed and the directory is always put as the last in the table.
35473 Write the path files at the end of these accumulations.
35475 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35476 Files_Htable for all sources.
35478 * prj-proc.adb (Process): Remove restrictions between not directly
35479 related extending projects.

35491 * scn.adb (Determine_License): Take into account a degenerated case
35492 when the source contains only comments.
35494 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35496 * sem_warn.adb (Check_References): For a warning on a selected
35497 component that does not come from source, locate an uninitialized
35498 component of the record type to produce a more precise error message.
35500 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35502 * 3zsoccon.ads: Fix multicast options.
35504 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35507 2004-03-15 Robert Dewar <dewar@gnat.com>
35509 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35510 pragma used for a private type.
35512 * lib-xref.adb (Generate_Reference): Do not generate warning if
35513 reference is in a different unit from the pragma Unreferenced.
35515 * 5vtpopde.adb: Minor reformatting
35516 Fix casing of To_Task_ID
35518 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35519 flag if we have an unchecked conversion to an access type in the same
35522 2004-03-15 Geert Bosch <bosch@gnat.com>
35524 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35525 imaginary parts, use Double precision throughout.
35527 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35528 we want to be able to compile run-time with -gnata for testing, but
35529 this may also be instantiated in user code that is compiled with -gnata.
35531 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35533 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35534 codes. Having a separate type for this is useful to enforce consistency
35535 throughout the various run-time units.
35536 (Exception_Data): Use Exception_Code for Import_Code.
35538 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35539 Natural and Integer in various places.

35541 with the severity bits masked off.
35542 (Register_VMS_Exception): Handle the additional exception data pointer

35548 occurrence matches some handler choice specification. Extracted out of
35549 get_action_description_for, and expanded to take care of the VMS
35551 (get_action_description_for): Use is_handled_by instead of an explicit
35552 complex condition to decide if the current choice at hand catches the
35553 propagated occurrence.
35555 * raise.h (Exception_Code): New type for C.
35557 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35558 System.Standard_Library.Exception_Code, to allow references from the
35559 pragma import/export expander.
35561 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35562 New accessors to allow easy access to GNAT exception data
35564 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35565 redundant Handled_By_Others component, helper for the personality
35566 routine which will now be able to call the appropriate exception data
35569 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35570 component of Standard_Exception_Type to be the closest possible to
35571 Exception_Code in System.Standard_Library, that we cannot get at this
35572 point. Expand a ??? comment to notify that this type node should
35573 probably be rewritten later on.
35575 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35576 registration call to include a pointer to the exception object in the
35579 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35580 instead of int and explicit bitmasks.
35582 2004-03-15 Vincent Celier <celier@gnat.com>
35584 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35585 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35587 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35588 longer needed now that it is in the spec of
35589 System.Tasking.Task_Attributes.
35591 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35593 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35595 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35597 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35598 taken care of in Scan_Make_Arg.
35599 (Scan_Make_Arg): Add the executable suffix only if the argument
35600 following -o, in canonical case, does not end with the executable
35601 suffix. When in verbose mode and executable file name does not end
35602 with executable suffix, output the executable name, in canonical case.
35604 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35605 to avoid warnings when instantiating Ada.Task_Attributes.
35608 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35609 in the correct order.
35611 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35612 redirect standard output and error to a file for the invocation of the
35613 compiler, then read the file.
35615 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
35616 directory, instead of the Value.
35617 (Find_Source_Dirs): Remove useless code & comments.
35619 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35621 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35622 tagged type is inherited, and the parent operation is not frozen yet,
35623 force generation of a freeze node for the inherited operation, so the
35624 corresponding dispatch entry is properly initialized.
35625 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35626 when looking for user-defined equality operation.
35628 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35629 boolean when locating primitive equality of tagged component.
35631 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
35632 bit-aligned field and the right-hand side a string literal, introduce
35633 a temporary before expanding assignment into a loop.
35635 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35636 priority in full, to ensure that any expanded subepxressions of it are
35637 elaborated in the scope of the init_proc.
35639 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35640 after object declaration, skipping over code that may have been
35641 generated for validity checks.
35643 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35644 discriminants, ignore the known discriminants of its full view, if
35645 any, to check legality.
35647 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35648 component if type has unknown discriminants.
35649 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35650 null if type has unknown discriminants.
35652 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference

36575 checks for bitfield creation are triggered.
36576 (finish_record_type): During last pass over the fields, clear
36577 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

36919 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
36920 generated to rename a generic actual, go to the actual itself, the

37031 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate

37036 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37037 N_String_Literal node always references an E_String_Literal_Subtype
37038 entity. This may not be true in the future.
37039 (Possible_Bit_Aligned_Component): Move processing of
37040 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37042 * exp_ch6.adb (Expand_Thread_Body): Pick up

37044 by possible -Dnnn binder parameter.

37047 (Type_May_Have_Bit_Aligned_Components): New function.

37087 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37088 ineffective elaborate all pragmas on non-visible packages (this
37089 happened when a renamed subprogram was called). Now the elaborate all
37090 always goes on the package containing the renaming rather than the one
37091 containing the renamed subprogram.
37093 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37094 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37119 * make.adb (Gnatmake): Special process for files to compile/check when
37120 -B is specified. Fail when there are only foreign mains in attribute
37121 Main of the project file and -B is not specified. Do not skip bind/link

37153 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37155 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37156 all attributes, including read-only attribute.

37192 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37193 protected objects when allocator has a subtype indication, not a

37195 checked when limited aggregates are implemented.

37198 pure, emit warning.

37308 * 5zinit.adb: Clean up.
37310 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37311 to __gnat_map_signal, imported from init.c to support
37312 signal -> exception mappings that depend on the vxWorks version.
37315 Created and exported __gnat_map_signal to support signal -> exception
37316 mapping that is dependent on the VxWorks version.

37345 Minor reformatting throughout
37347 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37349 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37350 bounds of a loop, create a separate block in order to generate proper
37351 cleanup actions to prevent memory leaks.
37353 * sem_res.adb (Resolve_Call): After a call to
37354 Establish_Transient_Scope, the call may be rewritten and relocated, in

37373 2003-12-08 Robert Dewar <dewar@gnat.com>
37375 * 7sintman.adb: Minor reformatting
37377 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37378 standard linker options to get standard libraries linked. We now plan
37379 to provide dummy versions of these libraries to match the appropriate
37380 configurable run-time (e.g. if a library is not needed at all, provide
37381 a dummy empty library).
37383 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37384 options (-L parameters and standard libraries). What we plan to do is
37385 to provide dummy libraries where the libraries are not required.
37387 * gnatbind.adb: Minor comment improvement
37389 2003-12-08 Javier Miranda <miranda@gnat.com>
37391 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37399 of aggregate with default initialized components.
37400 (Has_Default_Init_Comps): Improve implementation to recursively check
37401 all the present expressions.
37403 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37404 to indicate that the initialization call corresponds to a
37405 default-initialized component of an aggregate.
37406 In case of default initialized aggregate with tasks this parameter is
37407 used to generate a null string (this is just a workaround that must be
37408 improved later). In case of discriminants, this parameter is used to
37409 generate a selected component node that gives access to the discriminant
37412 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37413 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37414 allocated aggregates with default-initialized components.
37416 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37417 the box notation is used in positional aggregates.

37459 Process nodes N_Comment.
37461 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37462 without comments and there are some comments, set the flag
37463 Unkept_Comments to True.

37505 Correct typo in comment
37506 (Resolve_Aggregate): In case of array aggregates set the estimated
37507 type of the aggregate before calling resolve. This is needed to know
37508 the name of the corresponding IP in case of limited array aggregates.
37509 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37510 in case of default initialized array components.
37512 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37532 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37533 they are automatically generated by Make-lang.in and cause nothing but
37534 maintenance troubles.
37536 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37538 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37552 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37553 to ensure that the kernel fills in the interrupted context structure
37554 before calling a signal handler, which is necessary to be able to
37555 unwind past it. Update the copyright notice.
37557 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37559 * a-elchha.ads: New file.

37646 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37649 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37650 is legal in an instance, because legality is cheched in the template.

37671 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37672 so that the debugger can reliably access the value of the parameter,

41201 2002-01-30 Richard Henderson <rth@redhat.com>
41203 * trans.c (tree_transform) [N_Loop_Statement]: Use
41204 expand_exit_loop_top_cond.

41221 (title page): Remove date.
41222 (general) Add @./@: where approriate, and two spaces after the
41223 full stop at the end of a sentence. Use @samp markup when
41224 referring concrete lexical entities (keywords, attribute names
41225 etc.), and @syntax for ARM grammar elements. Use @r for English

41240 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41241 function approach did not work well because of a side effect (the
41242 function call could reallocate the table which was being indexed
41243 using its result). Fixes ada/4851.

41281 * raise.c (__gnat_eh_personality): Exception handling personality
41282 routine for Ada. Still in rough state, inspired from the C++ version

41302 Add 2001 to copyright date
41304 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41305 need to force universal inlining for these cases.
41307 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41309 * s-taprob.adb: Minor clean ups so that this unit can be used in

41336 the argument of an initialization procedure.
41338 * trans.c (tree_transform, case of arithmetic operators): If result
41339 type is private, the gnu_type is the base type of the full view,
41340 given that the full view itself may be a subtype.

41574 containing the name of the Ada Main Program. This string is mainly
41575 intended for the debugger.

41610 2001-12-17 Laurent Pautet <pautet@gnat.com>
41613 Fix comment of Shutdown_Socket and Close_Socket. These functions
41614 should not fail silently because if they are called twice, this
41615 probably means that there is a race condition in the user program.
41616 Anyway, this behaviour is consistent with the rest of this unit.
41617 When an error occurs, an exception is raised with the error message
41618 as exception message.

41771 reference nodes, since this field is used in such nodes.

42957 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42958 instead of simple checksum.
42959 (CRC_Match): new function.
42960 (CRC_Error): new constant.
42962 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42963 a CRC now and not a simple checksum. A CRC uses lower-case hex
42964 letters, fixes ambiguity in parsing.
42966 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
42967 is what this variable will store.
42969 * bcheck.adb: Change reference to chechsum in comments by CRC.
42970 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42971 rename All_Checksum_Match to All_CRC_Match. Change due to API
42972 renaming since now GNAT does not use a simple checksum but a
42973 CRC using GNAT.CRC32.
42975 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42976 now and not anymore a simple checksum.

43013 Update comments for the CRC.
43015 * types.adb (Hex): Use lowercase for the letter part.
43017 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43018 for a word. This is currently used only for CRC. In previous version,
43019 the checksum was using a representation with all letter being
43020 upper-case. With the new implementation (using CRC) we do not remove
43021 the 32th bit of the CRC, so we can have an upper-case starting letter
43022 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43023 It is ambigous since the CRC was optional and could be followed by
43024 options like EB, EE. So now this routines uses lower-case letter for
43025 the hexadecimal representation. Strange enough only lower case letters
43026 where checked in Scan_ALI (even if this was not a possible case).
43028 * gnatvsn.ads (Library_Version): changed to 3.15a.
43030 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43033 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

43037 Add 2001 to copyright notice
43038 (Accumulate_Checksum): Modify to use System.CRC32.

43044 Keep the change for lower case letters in the checksum.
43046 * ali.ads: Undo previous change not needed.
43048 * bcheck.adb: Undo most of previous change, not needed.
43049 But do use Checksums_Match for checksum comparison.
