8371 (Find_Primitive_Operation): New function.
8372 (Analyze_Overloaded_Selected_Component): insert explicit dereference
8373 only once if several interpretations of the prefix yield an access type.
8374 (Try_Object_Operation): Code and comment cleanup.
8375 (Analyze_Selected_Component): Reorder local variables. Minot comment and
8376 code reformatting. When the type of the prefix is tagged concurrent, a
8377 correct interpretation might be available in the primitive and

8410 disabled, perform regular analysis.
8411 (Check_Triggering_Statement): New routine.
8412 (Analyze_Requeue): Exclude any interpretations that are not entries when
8413 checking overloaded names in a requeue. Also test type conformance for
8414 matching interpretations rather than requiring subtype conformance at

8444 (Collect_Interfaces_Info): Minor update to handle the two secondary
8445 dispatch tables. Update occurrence of Related_Interface to Related_Type.
8446 (Generate_Parent_Ref): Add parameter to specify entity to check
8447 (Is_Preelaborable_Expression): Allow the name of a discriminant to
8448 initialize a component of a type with preelaborable initialization.
8449 This includes the case of a discriminal used in such a context.
8450 (Is_Dependent_Component_Of_Mutable_Object): Take into account the
8451 latest Ada 2005 rules about renaming and 'Access of
8452 discriminant-dependent components.

8902 (Set_Value): W is allocated on the heap.
8904 * g-socket.adb: Use 'Access instead of 'Unchecked_Access when
8906 (Get_Socket_Option): Optlen formal of C_Getsockopt is of an anonymous
8908 (Receive_Socket): Fromlen formal of C_Recvfrom is of an anonymous
8911 * s-taasde.adb: Use 'Access instead of 'Unchecked_Access when
8913 (elaboration code): Timer_Queue lifetime is the one of the
8916 * tracebak.c (i386 alternative): Remove useless comparaison
8917 which is always false; LOWEST_ADDRESS is 0 and is never greater
8918 than an unsigned integer.
8920 * sem_attr.adb (Analyze_Attribute): Remove duplicate identical
8921 embedded check for "Ada_Version >= Ada_05".

9003 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
9005 (Xref_Record): Change type for Line, since in the case of a reference to
9006 a predefined entity (as happens for array index types), the line is set
9008 Add support for parsing multiple array index types info, or
9009 multiple inherited interfaces info. This information cannot be stored
9010 in Xref_Entity_Record, which only supports a single instance of Tref_*,
9011 and is therefore stored in the list of references instead. It has a
9012 special treatement later on in tools that use this information.
9014 2007-10-15 Tristan Gingold <gingold@adacore.com>
9016 * debug.adb: Document use of -gnatd.a and -gnatd.I

9022 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
9023 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
9024 care of access to class-wide interface types plus removal of bizarre
9025 conversion of tagged object to access type (reported by Gary
9026 Dismukes). After this patch there is no need to perform any
9027 additional management on these nodes in Expand_Interface_Actuals.
9029 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9030 that handles use of 'Access and 'Unchecked_Access applied to
9031 actuals covering interface types. Such code is now
9032 centralized in Expand_N_Attribute_Reference.
9034 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9036 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
9037 of tagged types whose ultimate ancestor is a CPP type.

9062 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
9063 the generic Heap_Sort_G, in order to avoid trampolines.

9076 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9077 used by VxWorks targets to have access to task-specific data and be
9078 able to extract the stack boundaries for stack checking.
9079 Use system-vms-ia64.ads on ivms.
9081 * Make-lang.in: Update dependencies.
9083 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

9100 95 reserved word in its name.
9101 (Process_Project_Level_Array_Attributes): Process new attribute
9102 Runtime_Library_Dir.
9104 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9105 config project against the user project names.

9120 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9122 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9123 association for an access component, add an association with null as
9124 the expression. Remove testing for array subtypes and the setting in
9125 that case of Ctyp to the array component type, which prevented proper
9126 inclusion of an association for null-initialized arrays. Collapse
9127 condition that tests for array subtypes into just a test of
9128 Is_Partially_Initialized_Type (which already covers arrays anyway).
9130 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

9139 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9140 flag of derived concurrent types, taking into account the flag setting
9141 on the parent subtype and any new set of discriminants.
9143 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9145 * sem_ch4.adb: Minor code and comment reformatting.
9146 (Analyze_Allocator): When the designated type of an unconstrained
9147 allocator is a record with unknown discriminants or an array with
9148 unknown range bounds, emit a detailed error message depending on the
9149 compilation mode and whether the designated type is limited.

9282 type of file_info_ptr parameter.
9283 If mapped location support is enabled, create the isomorphic mapping
9284 between source files and line maps.
9285 (Sloc_to_locus): If mapped location support is enabled, translate
9286 source location into mapped location.
9287 (annotate_with_node): Rename into set_expr_location_from_node.

9311 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9313 * a-calend-vms.adb, a-calend.adb:
9314 Add a section on leap seconds control along with two entities used to
9315 enable and disable leap seconds support. The array Leap_Second_Times is
9316 now constant and contains hard time values pre-generated. Remove
9317 all elaboration code used to populate the table of leap seconds.
9320 Add entity Leap_Seconds_Support to the list of global run-time variables
9321 along with a comment on its usage and values.
9322 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9350 2007-09-26 Olivier Hainque <hainque@adacore.com>
9352 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
9353 #include <utime.h> and #define GCC_RESOURCE_H before
9354 #include <sys/wait.h>.
9355 Add more protections in __gnat_translate_vms.
9357 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
9358 #include <sys/wait.h>.
9360 2007-09-26 Thomas Quinot <quinot@adacore.com>

9363 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9365 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9368 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9370 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9373 * sem_dist.ads: Minor comment fix

9378 Eric Botcazou <ebotcazou@adacore.com>
9381 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9382 indirection added to the HT_Link component of the TSD. This is required
9383 to statically allocate the TSD.
9386 Minor reordering of the declarations in the private part. Required to
9387 add a level of indirection to the contents of the TSD component HT_Link.
9388 This is required to statically allocate the TSD.
9390 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9391 Is_Statically_Allocated set from constant objects.
9392 Do not make exported constants created by the compiler volatile.
9393 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9396 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9397 before returning them.

9402 purpose Make_DT now declares a separate object that stores the
9403 HT_Link value, and initializes the TSD component with the address
9404 of this new object. The addition of this level of indirection is
9405 required to statically allocate the TSD because the TSD cannot
9406 have variable components.
9407 (Expand_Interface_Conversion): Improve the expanded code.
9408 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9410 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9411 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9412 if we are building static dispatch tables then we must not generate
9413 extra code to register the primitive because the dispatch table will
9414 be built at the end of the library package; otherwise we notify that
9415 we cannot build the static dispatch table.
9417 2007-09-26 Robert Dewar <dewar@adacore.com>
9419 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9437 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9438 associated with interface types.
9439 Extensive comment fixes regarding flags that appear in all entities. The

9441 of errors in the documentation in this regard).
9443 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9445 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9446 of these procedures are passed a function call that already has
9447 build-in-place actuals (testing new flag
9448 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9449 the case where processing continues.
9450 (Expand_Call): If the call is generated from a thunk body then we
9451 propagate the extra actuals associated with the accessibility
9452 level of the access type actuals.
9454 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9455 of each extra formal of a protected operation to reference the

9485 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9486 whether an expression can be used within a type declaration that
9487 requires preelaborable init.

9489 preelaborable default expressions with call to
9490 Is_Preelaborable_Expression.
9491 (Has_Preelaborable_Initialization): In the case of a generic actual
9492 subtype, (that is, Is_Generic_Actual is True), return the result of
9493 applying Has_Preelaborable_Initialization to the generic actual's base

9501 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9502 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9503 avoids calling Time_Of and Split, thus making it more efficent.
9504 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9506 * g-calend.ads (Week_In_Year): Change comment to reflect new

9513 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9514 support for defining how switches can be grouped on a command line (as

9516 used as aliases for more complex switches (-gnatwa is same as
9518 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9519 (Start, Current_*): New subprograms
9520 Added support for parsing an array of strings in addition to the real
9522 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9523 be moved from the body to the private part of the spec.
9524 (*): All subprograms now have an extra parameter with default value to
9525 specify which parser should be used. For backward compatibility, it
9526 defaults to parsing the command line of the application. They were also
9527 modified to properly handle cases where each of the argument does not
9528 start at index 1 (which is always true for Ada.Command_Line, but not
9529 when processing any Argument_List).
9530 (Free): New subprogram
9531 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9532 Argument): New subprograms
9533 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9534 special characters like ':', '=',... are now handled in a single place,
9535 which makes the code more extensible eventually.
9536 (Getopt, Full_Switch): When the switch was returned as part of the
9537 special character '*', make sure it is prepended by the switch character
9538 ('-' in general), so that the application knows whether "foo" or "-foo"
9539 was specified on the command line.

9546 value before propagating the exception.
9548 2007-09-26 Vincent Celier <celier@adacore.com>
9550 * gnatbind.adb: If there are several ALI files specified and there is
9551 a main program to bind, the first ALI is expected to contain the main
9552 subprogram and the names of the binder generated files will be derived
9553 from the first ALI file name.
9554 (Gnatbind): Fix insertion character in invocation of Error_Msg
9556 2007-09-26 Vincent Celier <celier@adacore.com>
9558 * gnatcmd.adb (Check_Files): Do not include sources that have been
9559 removed by attributes Exclude_Source_Files or Locally_Removed_Files.

9564 information about each of its index types, following the type
9565 reference for its component type.

9595 attributes for gprbuild. No impact on GNAT tools.
9597 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9598 process configuration attributes: this is done in Prj.Nmsc.Check.
9599 (Recursive_Process): Make a full copy of packages inherited from project
9600 being extended, instead of a shallow copy.
9601 (Process_Project_Tree_Phase_1): New procedure

9603 (Process): Implementation now uses the two new procedures
9605 * prj-util.adb (Executable_Of): Get the suffix and the default suffix

9932 Thomas Quinot <quinot@adacore.com>
9934 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9935 create an abstract subprogram in the case of 'Input. For 'Output we now
9936 create a real spec/body when the type is abstract, since it can
9937 potentially be called.
9938 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9939 body for 'Output when the type is abstract (only the creation of the
9940 body for 'Input is excluded when the type is abstract).
9941 (Stream_Operation_OK): Add an additional condition in the return
9942 statement, so that False will be returned for TTS_Stream_Input if the
9943 associated tagged type is an abstract extension. Add comments for
9945 (Expand_N_Object_Declaration): For the case of a shared passive
9946 variable, insert init proc call only after the shared variable
9947 procedures have been processed, because the IP call needs to undergo
9948 shared passive variable reference expansion, which requires these
9949 procedures to be available (and elaborated).

9958 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
9959 given a box association, the type of the component is discriminated,
9960 and the value of the discriminant is the discriminant of the enclosing
9961 type, retrieve its value from the aggregate itself, where it must have
9964 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9965 to remove other spurious ambiguities on arithmetic operations involving
9966 literals and addresses, on systems where Address is a visible integer
9967 type, when the operator is called in functional notation.
9968 (Try_Primitive_Operation): Within an instance, a call in prefixed form
9969 is legal when the types match, even if the operation is currently
9972 2007-09-10 Ed Schonberg <schonberg@adacore.com>
9974 * sem_ch12.adb (Build_Local_Package): A formal package with no
9975 associations is legal if all formals have defaults. It is not
9976 equivalent to a formal declared with a box.

10009 which a constant renaming is treated as a normal object declaration.
10010 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
10011 the N_Indexed_Component case.
10012 <N_Indexed_Component>: Fall through to above case.

10094 (Write_Entity_Flags): Write the status of flag Is_Raised.
10095 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10096 spurious ambiguities when integer literals appear in the context of an
10097 address type that is a visible integer type.
10099 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10100 exceptions never being raised.
10101 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10117 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10118 library-level package renaming, pass the declaration associated with
10119 the renaming's special debug variable to Qualify_Entity_Names to ensure
10120 that its encoded name is properly qualified.
10122 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10123 occurring in the list of entities to qualify, and do not attempt to
10124 traverse an entity list in that case. Variables associated with
10125 ` library-level package renamings can now occur in the table.

10149 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10150 concatenations of string literals into a single literal, in order to
10151 avoid very deep recursion in the front end, which was causing stack
10154 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10155 string, and the right operand is a string literal (the case of "" &
10156 "..."), optimize by avoiding copying the right operand -- just use the
10157 value of the right operand directly.
10159 * stringt.adb (Store_String_Chars): Optimize by growing the
10160 String_Chars table all at once, rather than appending characters one by
10162 (Write_String_Table_Entry): If the string to be printed is very long,
10163 just print the first few characters, followed by the length. Otherwise,
10164 doing "pn(n)" in the debugger can take an extremely long time.
10166 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10167 Store_String_Char with Store_String_Chars.

10184 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10186 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10187 flag, for effiency. It is called when analyzing arithmetic operators
10188 and also for actuals in calls that are universal_integers. The flag is
10189 set for the predefined type address, and for any type or subtype
10192 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10193 Universal_Integer, when the formal is a descendent of address and the
10194 call appears in user code.
10195 (Analyze_Selected_Component): if the prefix is a private extension, the
10196 tag component is visible.
10198 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

10259 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10261 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10262 associated with Standard_Debug_Renaming_Type, to be used as the type of
10263 the special variables whose names provide debugger encodings for
10264 renaming declarations.
10266 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10267 (Set_Debug_Renaming_Link): Change to set Node25.

10270 "Debug_Renaming_Link".
10271 (Write_Field23_Name): Correct the output string for "Limited_View".
10273 * exp_dbug.adb: Add with and use of Tbuild.
10274 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10275 and literal with creation of a variable of type
10276 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10277 and the entity of the renaming declaration.
10278 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10279 part of the name of a variable that has a Debug_Renaming_Link.
10281 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10282 special type to be associated with variables that provide debugger
10283 encodings for renaming declarations.

10286 Ed Schonberg <schonberg@adacore.com>
10287 Javier Miranda <miranda@adacore.com>
10289 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10290 ancestor part given by an aggregate to test for an unchecked conversion,
10291 since this can occur in some cases when the ancestor part is a function
10292 call, and we don't want to fall into the recursive call to this
10293 procedure in that case.
10295 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10296 stream attributes on limited types to account for user-specified
10297 attributes as well as whether Input (resp. Output) becomes available
10298 due to Read (resp. Write) being available for the type. Change Boolean
10299 variable to the more accurate name
10300 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10301 double-"not" predicate at beginning of return statement to more
10302 understandable form.
10304 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10305 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10306 in a block statement and use that as the first statement of the
10307 expanded return rather than incorrectly using the handled sequence as
10308 the first statement.
10310 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10311 operation, generate an explicit freeze node for it rather than
10312 generating extra formals, to ensure that gigi has the proper order of
10313 elaboration for anonymous subtypes in the signature of the subprograms.
10314 (Build_In_Place_Formal): Move assertion to beginning of loop.
10315 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10324 * freeze.adb (Freeze_Record_Type): Extend the current management of
10325 components that are access type with an allocator as default value: add
10326 missing support to the use of qualified expressions of the
10327 allocator (which also cause freezing of the designated type!)
10328 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10329 dispatching operation, since extra formals may be needed by calls to
10330 build-in-place functions (such as stream 'Input).
10332 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10333 formals for 'Constrained and accessibility level in the case of a
10334 predefined dispatching operation.
10336 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10337 point, no need to find the parent node.

10342 and entry barriers.
10344 2007-08-16 Javier Miranda <miranda@adacore.com>
10346 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10347 is not really required and can introduce regression with the debugger.
10348 The original problem is fixed with the patch written for checks.adb.
10350 2007-08-16 Thomas Quinot <quinot@adacore.com>
10352 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10363 parameter Including_Non_Switch, defaulted to True. When
10364 Including_Non_Switch is False, options that are not switches and
10365 appear as relative path are not converted to absolute paths.

10389 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10390 generic for an enclosing instance is a global reference, even though
10391 its scope is the enclosing instance.

10417 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10418 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10419 the statement which is being resolved comes from a predefined library
10420 unit, all non-predefined library interpretations are skipped.
10421 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10422 but the "&" is user defined, give an error, because the folding would

10426 the parser has folded a long sequence of concatenations of string
10429 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"

10477 Ed Schonberg <schonberg@adacore.com>
10479 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10480 Suppress unmodified in-out parameter warning in some cases
10481 This patch is a also fairly significant change to the way suppressible
10482 checks are handled.
10484 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10485 needed for access to concurrent record types generated by the expander.
10486 (Generate_Range_Check): When generating a temporary to capture the
10487 value of a conversion that requires a range check, set the type of the
10488 temporary before rewriting the node, so that the type is always
10489 properly placed for back-end use.
10490 (Apply_Float_Conversion_Check): Handle case where the conversion is
10492 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10493 for a protected type in order to examine its discriminants.

10500 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10501 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10502 tests optimized out.
10504 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10505 (Get_Allocator_Final_List): For the case of an anonymous access type
10506 that has a specified Associated_Final_Chain, do not go up to the
10508 (Expand_N_Type_Conversion): Test for the case of renamings of access
10509 parameters when deciding whether to apply a run-time accessibility
10511 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10512 aggregate code before allocator, and ahead of declaration for
10513 temporary, to prevent access before elaboration when the allocator is
10514 an actual for an access parameter.
10515 (Expand_N_Type_Conversion): On an access type conversion involving an
10516 access parameter, do not apply an accessibility check when the
10517 operand's original node was an attribute other than 'Access. We now
10518 create access conversions for the expansion of 'Unchecked_Access and
10519 'Unrestricted_Access in certain cases and clearly accessibility should
10520 not be checked for those.
10522 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10523 includes a type conversion of a packed component that has been expanded,
10524 recover the original expression for the object, and use this expression
10525 in the post-call assignment statement, so that the assignment is made
10526 to the object and not to a back-end temporary.
10527 (Freeze_Subprogram): In case of primitives of tagged types not defined
10528 at the library level force generation of code to register the primitive
10529 in the dispatch table. In addition some code reorganization has been
10530 done to leave the implementation clear.
10531 (Expand_Call): When expanding an inherited implicit conversion,
10532 preserve the type of the inherited function after the intrinsic
10533 operation has been expanded.
10535 * exp_ch2.ads, exp_ch2.adb
10536 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10537 of an entry formal appearing in an assignment statement does not assign
10539 (Expand_Current_Value): Instead of calling a routine to determine
10540 whether the prefix of an attribute reference should be optimized or
10541 not, prevent the optimization of such prefixes all together.
10543 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10544 component whose prefix is known to be of an access type is an implicit
10545 dereference and does not assign to the prefix.
10547 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10548 Robert Dewar <dewar@adacore.com>
10550 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10551 itype is visited, make an entry into table to link associated node and
10553 Add comments and correct harmless error in Build_NCT_Hash_Tables
10554 (Array_Aggr_Subtype): Associate each itype created for an index type to
10555 the corresponding range construct, and not to the aggregate itself. to
10556 maintain a one-to-one correspondence between itype and its associated
10557 node, to prevent errors when complex expression is copied.
10558 Fix mishandling of multiple levels of parens
10560 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10561 treatment of limited views uniform for all visible declarations in a
10562 limited_withed package.
10563 (New_Copy_Tree): If hash table is being used and itype is visited,
10564 make an entry into table to link associated node and new itype.
10565 (Resolve_Record_Aggregate): Do not add an others box association for a
10566 discriminated record component that has only discriminants, when there
10567 is a box association for the component itself.
10569 * par-ch4.adb: Fix mishandling of multiple levels of parens
10571 2007-08-14 Robert Dewar <dewar@adacore.com>

10607 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10608 to make treatment of limited views uniform for all visible declarations
10609 in a limited_withed package.
10610 Improve warnings for in out parameters
10611 (Set_Related_Interaface/Related_Interface): Allow the use of this

10617 generation of a freezing node to ensure proper management of null
10618 excluding access types in the backend.
10619 (Create_Extra_Formals): Test base type of the formal when checking for
10620 the need to add an extra accessibility-level formal. Pass the entity E
10621 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10622 originally being done in a couple of cases), to ensure that the
10623 Extra_Formals list gets set on the entity E when the first entity is
10625 (Conforming_Types): Add missing calls to Base_Type to the code that
10626 handles anonymous access types. This is required to handle the
10627 general case because Process_Formals builds internal subtype entities
10628 to handle null-excluding access types.
10629 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10630 functions that need it, even when not marked Requires_Overriding.
10631 Improve warnings for in out parameters
10632 (Analyze_Function_Return): Warn for disallowed null return
10633 Warn on return from procedure with unset out parameter
10634 Ensure consistent use of # in error messages
10635 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10636 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10637 the implicit conversion of the expression done for anonymous access
10638 types. This is required to generate the code of the null excluding
10639 check (if required).
10641 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10642 A formal parameter is never publicly referenceable outside of its body.
10643 (Check_References): For an unreferenced formal parameter in an accept
10644 statement, use the same warning circuitry as for subprogram formal
10646 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10647 Output_Unreferenced_Messages, containing the part of that routine that
10648 is now reused for entry formals as described above.
10649 (Goto_Spec_Entity): New function
10650 (Check_References): Do not give IN OUT warning for dispatching operation
10651 Improve warnings for in out parameters

10661 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10662 (Expand_N_Attribute_Reference): Further unify the handling of the
10663 three forms of access attributes, using common code now for all three
10664 cases. Add a test for the case of applying an access attribute to
10665 an explicit dereference when the context is an access-to-interface
10666 type. In that case we need to apply the conversion to the prefix
10667 of the explicit dereference rather than the prefix of the attribute.
10668 (Attribute_Version, UET_Address): Set entity as internal to ensure
10669 proper dg output of implicit importation.
10670 (Expand_Access_To_Type): Removed.
10671 (Expand_N_Attribute_Reference): Merge the code from the three cases
10672 of access attributes, since the processing is largely identical for
10673 these cases. The substantive fix here is to process the case of a
10674 type name prefix (current instance case) before handling the case
10675 of interface prefixes.

10683 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10684 type that is an anonymous access to controlled object, establish
10685 an associated finalization chain to avoid corrupting the global
10686 finalization list when a dynamically allocated object designated
10687 by such a component is deallocated.
10688 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10689 functions that need it, even when not marked Requires_Overriding.

10701 the tag components of secondary dispatch tables.
10702 (Init_Secondary_Tags): New implementation that simplifies the previous

10705 object declaration, for diagnostic purposes.
10706 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10707 diagnose attemps to freeze a subprogram when some untagged type of its
10708 profile is a private type whose full view has not been analyzed yet.
10709 (Freeze_Array_Type): Generate init proc for packed array if either
10710 Initialize or Normalize_Scalars is set.
10711 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10712 constructing the new profile, copy the null_exclusion indicator for each
10713 parameter, to ensure full conformance of the new body with the spec.

10716 Create wrappers for constructor functions that need it, even when not
10717 marked Requires_Overriding.

10756 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10757 output of implicit importation and exportation.
10758 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10759 first formal of the thunk is always associated with the controlling
10760 type. In addition perform the following code cleanup: remove formal
10761 Thunk_Alias which is no longer required, cleanup evaluation of the
10762 the controlling type, and update the documentation.
10763 Replace occurrence of Default_Prim_Op_Count by
10764 Max_Predef_Prims. Addition of compile-time check to verify
10765 that the value of Max_Predef_Prims is correct.
10766 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10767 (Make_DT): Add parameter to indicate when type has been frozen by an
10768 object declaration, for diagnostic purposes.
10769 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10770 construction of statically allocated dispatch tables.
10771 (Make_DT): In case of library-level tagged types export the declaration
10772 of the primary tag. Remove generation of tags (now done by Make_Tags).
10773 Additional modifications to handle non-static generation of dispatch
10774 tables. Take care of building tables for asynchronous interface types
10775 (Make_Tags): New subprogram that generates the entities associated with
10776 the primary and secondary tags of Typ and fills the contents of Access_
10777 Disp_Table. In case of library-level tagged types imports the forward
10778 declaration of the primary tag that will be declared later by Make_DT.
10779 (Expand_Interface_Conversion): In case of access types to interfaces
10780 replace an itype declaration by an explicit type declaration to avoid

10787 * exp_util.ads, exp_util.adb:
10788 This patch replaces a number of occurrences of explicit tests for N_Null
10789 with calls to Known_Null. This improves tracking of null values, since
10790 Known_Null also catches null constants, and variables currently known to
10791 be null, so we get better tracking.
10792 (Ensure_Defined): create an itype reference only in the scope of the
10794 (Side_Effect_Free): A selected component of an access type that
10795 denotes a component with a rep clause must be treated as not
10796 side-effect free, because if it is part of a linked structure its
10797 value may be affected by a renaming.
10798 (Expand_Subtype_From_Expr): For limited objects initialized with build
10799 in place function calls, do nothing; otherwise we prematurely introduce
10800 an N_Reference node in the expression initializing the object, which
10801 breaks the circuitry that detects and adds the additional arguments to
10802 the called function. Bug found working in the new patch for statically
10803 allocated dispatch tables.
10804 (Is_Library_Level_Tagged_Type): New subprogram.
10805 (Remove_Side_Effects): If the expression of an elementary type is an
10806 operator treat as a function call.
10807 (Make_Literal_Range): If the index type of the array is not integer, use
10808 attributes properly to compute the constraint on the resulting aggregate
10811 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10812 class-wide type whose base type is an incomplete private type, leave
10813 class-wide type unfrozen so that freeze nodes can be generated
10814 properly at a later point.
10815 (Freeze_Entity, array case): Handle case of pragma Pack and component
10816 size attributre clause for same array.

11272 (Analyze_Compilation_Unit): If unit is a subprogram body that has no
11273 separate declaration, remove the unit name from visibility after
11274 compilation, so that environment is clean for subsequent compilations.

11347 reorganization and documentation update for the case of predefined
11348 library generics (for which we do not reference an Afile).

11444 (Set_Item): When the new item is an element of the currently allocated
11445 table passed by reference, save a copy on the stack if we're going
11446 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11447 variable to determine whether to call Set_Last.

11460 Thomas Quinot <quinot@adacore.com>
11462 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11463 derived type with interface progenitors use the analyzed formal as the
11464 parent of the actual, to create renamings for all the inherited
11465 operations in Derive_Subprograms.
11466 (Collect_Previous_Instances): new procedure within of
11467 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11468 unit being loaded, to ensure that the generation of global symbols is
11469 consistent in different compilation modes.
11470 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11471 takes progenitor types into account.
11472 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11473 traversing over the primitives of the formal and actual types to locate
11474 any abstract subprograms of the actual type that correspond to a
11475 nonabstract subprogram of the formal type's ancestor type(s), and issue
11476 an error if such is found.
11477 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11478 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11479 Remove bogus guard around calls to Inherit_Context.
11480 (Reset_Entity): If the entity is the selector of a selected component
11481 that denotes a named number, propagate constant-folding to the generic
11482 template only if the named number is global to the generic unit.
11483 (Set_Instance_Env): Only reset the compilation switches when compiling
11484 a predefined or internal unit.
11486 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11488 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11489 parameter to determine whether operation applies to the prefix.
11490 (Complete_Object_Operation): If actual has an access type and
11491 controlling formal is not an in_parameter, reject the actual if it is
11492 an access_to_constant type.
11493 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11494 type, the candidate operations are found in the scope of declaration of
11495 the type, because the type has no primitive subprograms.
11496 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11497 a private extension, only examine visible components before trying to
11498 analyze as a prefixed call.
11499 Change Entity_List to Type_To_Use, for better readability.
11500 (Has_Fixed_Op): Use base type when checking whether the type of an
11501 operator has a user-defined multiplication/division
11502 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
11503 user-defined operators are available for fixed-point types.

11506 Ed Schonberg <schonberg@adacore.com>
11508 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11509 formal At_Any_Place indicating, when True, that we want to test for
11510 availability of the stream attribute at any place (as opposed to the
11511 current visibility context only).
11512 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11513 purpose of enforcing E.2.2(8) only if it is not available at any place.
11514 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11515 when checking the legality of an extension aggregate in a preelaborable
11516 package. Treat the literal null as a valid default expression in a
11517 component declaration for a type with preelaborable initialization.
11518 A limited interface is a legal progenitor for the designated type of a
11519 remote access to class-wide type.

11528 setting the Referenced_As_LHS flag for entities that are implicitly
11530 (Find_Type): If the type is an internally generated incomplete type,
11531 mark the full view as referenced, to prevent spurious warnings.
11532 (Find_Selected_Component, Has_Components): Handle properly non-limited
11533 views that are themselves incomplete types.
11534 Handle interfaces visible through limited-with clauses.
11535 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11536 subprogram generic actual for which we have generated a renaming.
11537 Warn when the renaming introduces a homonym of
11538 the renamed entity, and the renamed entity is directly visible.

11541 Hristian Kirtchev <kirtchev@adacore.com>
11543 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
11544 appear in the subtree to the current allocator if it is not a static
11546 (Resolve_Allocator): Perform cleanup if resolution has determined that
11547 the allocator is not a coextension.
11548 (Resolve): Skip an interpretation hidden by an abstract operator only
11549 when the type of the interpretation matches that of the context.
11550 (Resolve): When looping through all possible interpretations of a node,
11551 do not consider those that are hidden by abstract operators.
11552 (Resolve_Actuals): When verifying that an access to class-wide object
11553 is an actual for a controlling formal, ignore anonymous access to
11554 subprograms whose return type is an access to class_wide type.
11555 (Resolve_Slice): If the prefix of the slice is a selected component
11556 whose type depends on discriminants, build its actual subtype before
11557 applying range checks on the bounds of the slice.
11558 (Valid_Conversion): In an instance or inlined body, compare root types,
11559 to prevent anomalies between private and public views.
11560 (Resolve): Improve error message for ambiguous fixed multiplication
11561 expressions that involve universal_fixed multiplying operations.

11581 elabration statements, register the package with the name server
11582 at the beginning, not at the end, of the elaboration statements so
11583 that they can create remote access to subprogram values that designate
11584 remote subprograms from the package.

11588 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
11589 values to compute the number of seconds since the Unix Epoc in order to

12638 (build_call_alloc_dealloc): When releasing a super-aligned object,
12639 retrieve the system's allocator return value from where build_allocator

12667 (Gen_Output_File_Ada, Gen_Output_File_C): Never use __attribute
12668 ((destructor)) for adafinal, even when switch -a is used.
12669 Do not issue pragma Linker_Destructor for adafinal when switch -a is
12671 (Gen_Object_Files_Options): Add formatting of Linker Options, when
12672 Output_Linker_Option_List is set. Suppress this formatting when
12673 Zero_Formatting is set.
12674 Add case for CLI_Target.

12710 (Get_E_Length): Protect against bomb in case scope is standard
12711 (Selected_Range_Checks): If the node to be checked is a conversion to
12712 an unconstrained array type, and the expression is a slice, use the
12713 bounds of the slice to construct the required constraint checks.
12714 Improve NOT NULL error messages
12715 (Apply_Constraint_Check): If the context is a null-excluding access
12716 type, diagnose properly the literal null.

12732 Arnaud Charlet <charlet@adacore.com>
12734 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12735 applicable to types that have the With_Type flag set. Returns the
12736 non-limited view of the type, if available, otherwise the type itself.
12737 For class-wide types, there is no direct link in the tree, so we have
12738 to retrieve the class-wide type of the non-limited view of the Etype.
12739 New attributes Static_Initialization and Static_Elaboration_Desired.
12740 Remove the pragma Thread_Body, and the associated flag
12741 Is_Thread_Body in entities, and all related code.
12742 (Suppress_Value_Tracking_On_Call): New flag
12743 E_Exception has Esize and Alignment fields
12744 (Universal_Aliasing): New function.

12751 components of records. Set to point to the entity of the corresponding
12753 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
12754 (Original_Access_Type): Remove, not needed.
12755 (Root_Type): Handle properly subtypes of class-wide-types.
12758 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12759 class-wide types visible through limited-with clauses.
12760 (Try_Primitive_Operation): When examining all primitive operations of a
12761 tagged type, do not consider subprograms labeled as hidden unless they
12762 belong to a private generic type with a tagged parent.
12763 (Try_Object_Operation): Extensive rewriting, to handle properly various
12764 overloading cases, when several ancestors may have class-wide operations
12765 that are possible candidates, and when the overloaded functions return
12766 array types and have defaulted parameters so that the call may be
12767 interpreted as an indexing.
12768 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12769 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12770 successive actuals before analyzing the call itself.
12771 (Try_Primitive_Operation): A primitive operation is compatible with the
12772 prefix if the prefix has a synchronized type and the type of the formal
12773 is its corresponding record, as can be the case when the primitive
12774 operation is declared outside of the body of the type.
12775 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12776 perform homonym traversal, looking for class-wide operation matches
12777 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12778 access parameters are now restricted to anonymous access types.
12779 (Mark_Allocator): An allocator with a discriminant association parent is
12781 (Try_One_Prefix_Interpretation): If the type of the object is
12782 incomplete, as can be happen when it is a limited view obtained through
12783 a limited_with_clause, the selected component is not part of a prefixed
12785 (Complete_Object_Operation): Diagnose properly an object that is not
12786 aliased when the corresponding controlling formal is an access
12788 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12789 ambiguous calls in prefixed notation, where two primitives differ only
12790 in that the controlling argument of one is an access parameter.
12792 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12793 whether a function that returns an unconstrained type can be inlined.
12794 (Process_Formals): Diagnose properly the illegal use of an incomplete
12795 type in the profile of an access_to_subprogram declaration.
12796 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12797 operations are attached to the corresponding record.
12798 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12799 When processing a primitive of a concurrent type which implements an
12800 interface change the type of all controlling formals to that of the
12801 corresponding record type.
12802 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12803 to determine the tagged type to which a primitive belongs.
12804 (Check_Conventions): Capture condition to ignore a primitive operation
12805 (which is shared between the loop in Check_Conventions and the one in
12806 Check_Convention) in a new local function Skip_Check.
12807 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12808 confusion with Check_Conventions' own Prim_Op local variable.
12809 (Create_Extra_Formals): Test for a tagged result type rather than a
12810 controlling result when determining whether to add a BIP_Alloc_Form
12811 formal and a BIP_Final_List formal to the function.
12812 (Check_Conformance); For parameters that are anonymous access types,
12813 subtype conformance requires that the not null and the constant
12814 indicators must match
12815 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12816 to retrieve the appropriate type when processing a concurrent type
12817 declared within a generic. Minor comment reformatting. Change invocation
12818 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12820 (Analyze_Subprogram_Body): If the return type of a function is an
12821 anonymous access to the limited view of a class-wide type, and the
12822 non-limited view of the type is available, update the type of the
12823 function so that code can be generated.
12824 (Process_Formals): In case of access-subtype itype whose designated
12825 type is also an itype (situation that happens now with access to
12826 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12827 attribute to avoid backend problems.
12828 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12829 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12830 anonymous types' designated types are same before testing
12831 Subtypes_Statically_Match.
12832 (Create_Extra_Formals): Test for a named access parameter that is a
12833 controlling formal as an additional condition for adding an
12834 accessibility level formal. This can occur in the subp type created for
12835 dispatching calls in Expand_Dispatching_Call, and allows calling
12836 Create_Extra_Formals from that procedure rather than special-casing the
12837 extra formals there.
12838 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12839 when the function has a controlling result.
12840 (Check_Returns): Add much more knowledge of the optimization of local
12841 raise statements to gotos, to retain proper warnings in this case.
12842 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12843 nodes when looking for last statement.
12845 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12846 class-wide types visible through limited with clauses.
12847 (Add_One_Interp): If the operands are anonymous access types, the
12848 predefined operator on universal_access is immediately visibles
12849 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12850 other anonymous access types.
12851 (Disambiguate): Take into account CIL convention.
12852 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12854 2007-06-06 Robert Dewar <dewar@adacore.com>

12859 Fix lower bound of tables.
12862 * nlists.adb: Ditto.
12863 (Prev_Node, Next_Node): Change index type to Int so that it properly

12866 2007-06-06 Javier Miranda <miranda@adacore.com>
12867 Ed Schonberg <schonberg@adacore.com>
12868 Bob Duff <duff@adacore.com>
12869 Hristian Kirtchev <kirtchev@adacore.com>
12871 * exp_aggr.ads, exp_aggr.adb:
12872 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12873 in extension aggregates.
12874 (Flatten): Other conditions being met, an aggregate is static if the
12875 low bound given by component associations is different from the low
12876 bound of the base index type.
12877 (Packed_Array_Aggregate_Handled): If the component type is itself a
12878 packed array or record, the front-end must expand into assignments.
12879 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12880 Init_Pr, instead of Ancestor_Is_Expression.
12881 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12882 coextension chain root, either generate a list controller or use the
12883 already existing one.
12884 (Static_Array_Aggregate): New procedure to construct a positional
12885 aggregate that can be handled by the backend, when all bounds and
12886 components are compile-time known constants.
12887 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12888 types covering interface types into assignments.
12889 (Replace_Type): move to Build_Record_Aggr_Code.
12890 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12891 interface type, convert to the definite type of the aggregate itself,
12892 so that needed components are visible.
12893 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12894 components and the context is an extended return statement do not
12895 create a transient block for it, to prevent premature finalization
12896 before the return is executed.
12897 (Gen_Assign): Do not generate a call to deep adjust routine if the
12898 component type is itself an array of controlled (sub)-components
12899 initialized with an inner aggregate.
12900 (Component_Check): New name for Static_Check. This name is now more
12901 appropriate, and documentation is added which was missing.
12902 (Component_Check): Add test for bit aligned component value
12903 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12904 Tagged_Comps, name is more appropriate given added function below.
12905 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
12907 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
12908 Javier Miranda <miranda@adacore.com>
12909 Robert Dewar <dewar@adacore.com>
12911 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12912 Terminated: Add unchecked type conversion from System.Address to
12913 System.Tasking.Task_Id when calling the predefined primitive
12915 Disable new Ada 05 accessibility check for JVM.NET targets, which
12916 cannot be implemented in a practical way.
12917 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12918 the sources always references the tag of the actual object. Therefore,
12919 if 'Tag is applied in the sources to class-wide interface objects we
12920 generate code that displaces "this" to reference the base of the object.
12921 (Expand_N_Attribute_Reference, case Size): Return specified size if
12922 known to front end.
12923 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12924 has code that displaces the pointer of the object to manage interface
12925 types. However this code must not be executed when the prefix is a
12926 subprogram. This bug caused the wrong expansion of the internally
12927 generated assignment that fills the dispatch table when the primitive
12928 is a function returning a class-wide interface type.
12929 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12930 Set_Attribute_Name for Name_Unaligned_Valid.
12932 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12933 Gary Dismukes <dismukes@adacore.com>
12935 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12936 If the initialization is the equivalent aggregate of the initialization
12937 procedure of the type, do not remove it.
12938 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12939 initialized to null from having their expression reset to empty and
12940 note this exception in the comment.

12956 (Requires_Simple_Name_Prefix): Body of new function.
12957 (Resolve_Attribute, case Access): Improve error message for case of
12958 mismatched conventions.
12959 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12961 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12962 constrained subtype for a nominal unconstrained type, use its base type
12963 to check for conformance with the context.
12964 (Resolve_Attribute): Remove test of the access type being associated
12965 with a return statement from condition for performing accessibility
12966 checks on access attributes, since this case is now captured by
12967 Is_Local_Anonymous_Access.
12968 (Analyze_Access_Attribute): Set Address_Taken on entity
12969 (Analyze_Attribute, case Address): Set Address_Taken on entity
12970 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12971 validating an access attribute whose prefix is a current instance.
12972 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12973 applied to dispatching operations, if freezing is required then we set
12974 the attribute Has_Delayed_Freeze in the prefix's entity.
12975 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12976 current scope if access of local subprogram taken
12977 (Analyze_Access_Attribute): Check legality of self-reference even if the
12978 expression comes from source, as when a single component association in
12979 an aggregate has a box association.
12980 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12981 the prefix if it is a protected operation and the attribute is
12982 Unrestricted_Access.
12983 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12984 reference to the base type of the context, to force a constraint check
12985 when the context is an access subtype with an explicit constraint.
12986 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12987 node is rewritten as an interface conversion. leave unanalyzed after
12988 resolution, to ensure that type checking against the context will take

12992 Javier Miranda <miranda@adacore.com>
12993 Robert Dewar <dewar@adacore.com>
12995 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12996 wrapper when the full view of the controlling type of an inherited
12997 function that dispatches on result implements interfaces.
12998 (Expand_N_Object_Declaration): In cases where the type of the
12999 declaration is anonymous access, create finalization list for it.
13000 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13001 if the object has no explicit initialization, to match description of
13002 functionality of pragam Persistent_BSS.
13003 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13004 new function to build static aggregates, to replace initialization call
13005 when static initialization is desired.
13006 (Freeze_Type): Generate a list controller for an access type whenever
13007 its designated type has controlled anonymous access discriminants.
13008 (Build_Equivalent_Aggregate): New procedure to compute a static
13009 aggregate to be used as default initialization for composite types,
13010 instead of a generating a call to the initialization procedure for the
13012 (Build_Initialization_Call): When available, replace a call to the
13013 initialization procedure with a copy of the equivalent static aggregate
13015 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13016 declarations for objects of a class-wide interface type, rather than
13017 just identifiers, to prevent visibility problems.
13018 (Expand_N_Object_Declaration): When expanding the declaration for an
13019 object of a class-wide interface type, preserve the homonym chain of
13020 the original entity before exchanging it with that of the generated
13021 renaming declaration.
13022 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13023 active, because there is no way to handle the exception.
13024 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13025 to do a minimum decoration of the Access_Disp_Table list.
13026 (Expand_Record_Controller): Avoid the addition of the controller between
13027 the component containing the tag of a secondary dispatch table and its
13028 adjacent component that stores the offset to the base of the object.
13029 This latter component is only generated when the parent type has
13030 discriminants ---documented in Add_Interface_Tag_Components).
13031 (Apply_Array_Size_Check): Removed, no longer needed.
13032 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13033 components, create a Master_Entity for it only if it contains tasks.
13034 (Build_Init_Procedure): Suppress the tag assignment compiling under
13036 (Freeze_Record_Type): Remove code associated with creation of dispatch
13038 (Init_Secondary_Tags): Update type of actuals when generating calls to
13039 Ada.Tags.Set_Offset_To_Top
13040 (Stream_Operation_OK): Disable use of streams compiling under no
13042 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13043 if Has_Init_Expression set.
13044 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13045 Register_Primitive, which provides the same functionality.
13046 (Requires_Init_Proc): Return false in case of interface types.
13047 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13049 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13050 is always associated with a predefined primitive because the internal
13051 entities associated with interface types are not predefined primitives.
13052 Therefore, the call to Is_Internal is replaced by a call to the
13053 function Is_Predefined_Dispatching_Operation.
13054 (Make_Eq_If): When generating the list of comparisons for the
13055 components of a given variant, omit the controller component that is
13056 present if the variant has controlled components.
13058 2007-06-06 Javier Miranda <miranda@adacore.com>
13059 Hristian Kirtchev <kirtchev@adacore.com>
13060 Bob Duff <duff@adacore.com>
13062 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13063 handle the creation of finalization lists and calls for nested
13064 coextensions when the root of the chains is part of a return statement.
13065 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13067 (Expand_Record_Equality): Skip components that are interface types.
13068 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13069 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13070 with Rewrite_Coextension. Change the condition for detecting coextension
13072 (Is_Local_Access_Discriminant): Removed.
13073 (Rewrite_Coextension): New routine which rewrites a static coextension
13074 as a temporary and uses its unrestricted access in the construction of
13076 (Complete_Coextension_Finalization): New routine. Generate finalization
13077 attachment calls to all delayed coextensions.
13078 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13079 the allocator is not a coextension itself and has delayed coextensions.
13080 If the current allocator is controlled, but also a coextension, delay
13081 the generation of the finalization attachment call.
13082 Rename local variable "Node" to "Nod" in order to avoid confusion with
13084 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13085 limited types that are not inherently limited. Such an allocator is
13086 illegal, but is generated by the expander for a return statement, to
13087 copy the result onto the secondary stack. This is the only case where a
13088 limited object can be copied. Generate code to displace the pointer
13089 to the object if the qualified expression is a class-wide interface
13090 object. Such displacement was missing and hence the copy of the object
13092 (Apply_Accessibility_Check): Handle allocated objects initialized in
13094 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13095 and Expand_Allocator_Expression. Allocating class-wide interface objects
13096 this routine displaces the pointer to the allocated object to reference
13097 the component referencing the corresponding secondary dispatch table.
13098 Expand_Allocator_Expression): Add missing support to allocate class-wide
13099 interface objects initialized with a qualified expression.
13100 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13101 function result type, and use the finalization list associated with the
13102 function scope in that case (such an anonymous type should not be
13103 treated like an access parameter's type).
13105 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13106 Gary Dismukes <dismukes@adacore.com>
13107 Javier Miranda <miranda@adacore.com>
13109 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13110 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13111 required exception handler.
13112 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13113 properly the case of a function whose return type is a limited
13114 class-wide interface type. Modify the code of the accessibility
13115 check to handle class-wide interface objects. In this case we need to
13116 displace "this" to reference the primary dispatch table to get access
13117 to the TSD of the object (to evaluate its accessibility level).
13118 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13119 rather than a controlling result as one of the conditions for
13120 generating tests of the implicit BIP_Alloc_Form formal. The
13121 initialization assignment is also handled according to whether the
13122 result is tagged instead of controlling.
13123 In the case where the init assignment is inserted in the "then" part of
13124 the allocation conditional, rewrite the target to be a dereference of
13125 the implicit BIP_Object_Access formal.
13126 If the returned value is unconstrained and created on the secondary
13127 stack, mark the enclosing block and function so that the secondary
13128 stack is not reclaimed on return.
13129 Treat returns from functions with controlling results similarly to
13130 returns from functions with unconstrained result subtypes.
13131 If the object returned is unconstrained, and an allocator must be
13132 created for it, analyze the allocator once the block for the extended
13133 return is installed, to ensure that finalizable components
13134 of the expression use the proper finalization list. Guard the call to
13135 Move_Final_List with a check that there is something to finalize.
13136 (Make_Tag_Ctrl_Assignment): Use "old" handling
13137 of controlled type assignment for virtual machines, since new code uses
13138 unsupported features (such as direct access to bytes in memory).
13140 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13141 Ed Schonberg <schonberg@adacore.com>
13143 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13144 accessibility actual, check for the case of an aliased object that has
13145 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13146 we fall into processing for the attribute rather than the name of the
13148 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13149 formal has its address taken in the body, create a temporary to capture
13150 value. If the return type is a limited interface, do not treat the
13151 return value as Controlled.
13152 (Is_In_Place_Function): If the return type is a limited interface,
13153 treat as returning in place. The actual returned object may not always
13154 be limited, but the caller has to assume that it is returned in place.
13155 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13156 context of an allocator, use the correct finalization chain (that is,
13157 the chain belonging to the access type, rather than the chain belonging
13158 to the current scope).
13159 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13160 result type rather than a controlling result as a precondition for
13161 adding an allocation form actual to a build-in-place call.
13162 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13163 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13164 primitive in the dispatch tables. This work is now done by Make_DT when
13165 the type is frozen.
13166 (Register_Predefined_DT_Entry): Removed.
13167 (Add_Return): If end label is not present, use sloc of last statement
13168 for generated return statement in procedure, for better gdb behavior
13170 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13171 object address nodes to ensure proper processing by routines like
13173 (Expand_Call): Fix generation of validity check for parameter
13174 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13175 the allocation form parameter if the result subtype is constrained,
13176 except when the function has a controlling result.
13177 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13178 rather than Is_Controlled and Has_Controlled_Component, since we want to
13179 include class-wide result types in this treatment. Also test for a
13180 controlling result, since that also requires passing a finalization
13182 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13183 even when the result subtype is constrained, to handle calls involving
13184 controlling results.
13185 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13186 is now called even when the result subtype is constrained, to handle
13187 calls involving controlling results.
13188 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13189 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13190 now performs the test).
13191 (Make_Build_In_Place_Call_In_Object_Declaration):
13192 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13193 constrained, to handle calls involving controlling results.
13194 (Add_Return): Accomodate rewritten pattern from local raise to goto
13195 transformation, so that we still recognize an transfer statement
13196 and do the right thing here in that case.
13197 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13198 and end of subprogram code.
13199 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13200 support for primitives that are functions (without formals) with a
13201 controlling result.
13202 (Inherited_From_Formal): If the actual subtype has not generic parent
13203 type, it is not an actual for a formal derived type, and there is no
13204 operation to inherit from the formal.

13207 Thomas Quinot <quinot@adacore.com>
13209 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13210 inserted cleanup code appropriately for GDB use.
13211 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13212 exception handler for Deep_Adjust or Deep_Finalize.
13213 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13214 Raise_From_Controlled_Operation is available, use a call to that
13215 subprogram instead of a plain "raise Program_Error" node to raise
13216 Program_Error if an exception is propagated from an Adjust or Finalize
13218 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13219 appears in the optional statement list of a triggering alternative, the
13220 scope actions can be inserted directly there, and not in the list that
13221 includes the asynchronous select itself.

13227 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13228 generated exception handler appropriately when debugging generated code.
13229 Deal properly with No_Exception_Propagation restriction mode.
13230 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13231 System.Address to System.Tasking.Task_Id when processing the result of
13232 the predefined primitive _disp_get_task_id.
13233 (Expand_N_Asynchronous_Select): Clarify comment.
13234 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13235 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13236 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13237 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13238 privals and for generated call to Complete_Entry_Body, for better gdb
13240 (Copy_Result_Type): Utility to construct a parameter and result profile
13241 for protected functions whose return type is an anonymous access to
13243 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13245 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13246 point when the local-raise-to-goto transformation has taken place.
13248 2007-06-06 Javier Miranda <miranda@adacore.com>
13249 Nicolas Setton <setton@adacore.com>
13251 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13252 functionality when the backend is generating code.
13253 Otherwise any serious error
13254 reported by the backend calling the frontend routine Error_Msg
13255 changes the Compilation_Mode to Check_Semantics, disables the
13256 functionality of this routine and causes the generation of
13257 spureous additional errors.
13259 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13260 debugging information now generated by the compiler for fat-pointer
13262 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13264 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13266 2007-06-06 Thomas Quinot <quinot@adacore.com>
13268 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13269 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13270 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13271 For a remote call to a function with a classwide return type, apply an
13272 E.4(18) check to the returned value.
13273 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13274 stream attributes of the designated type of an RACW, as they are not
13275 dispatching primitive operations.
13277 2007-06-06 Geert Bosch <bosch@adacore.com>
13279 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13281 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13283 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13284 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13286 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13288 2007-06-06 Javier Miranda <miranda@adacore.com>
13290 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13291 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13293 2007-06-06 Javier Miranda <miranda@adacore.com>
13295 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13296 deallocation of class-wide interface objects.
13297 (Expand_Dispatching_Constructor_Call): Take into account that if the
13298 result of the dispatching constructor is an interface type, the
13299 function returns a class-wide interface type; otherwise the returned
13300 object would be actual. The frontend previously accepted returning
13301 interface types because Expand_Interface_Actuals silently performed
13302 the management of the returned type "as if" it were a class-wide
13304 (Expand_Dispatching_Constructor_Call): Replace call to
13305 Make_DT_Access_Action by direct call to Make_Function_Call.
13307 2007-06-06 Robert Dewar <dewar@adacore.com>
13308 Ed Schonberg <schonberg@adacore.com>
13310 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13311 compute masking constant, since we now set Esize properly to the
13313 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13314 to match the alignment.
13315 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13316 packed arrays of 8 bits or less.
13318 * freeze.adb (Freeze_Entity): When freezing the formals of a
13319 subprogram, freeze the designated type of a parameter of an access type
13320 only if it is an access parameter.
13321 Increase size of C convention enumeration object
13322 (Freeze_Entity, array type case): Make sure Esize value is properly
13323 adjusted for the alignment if it is known.
13324 (Freeze_Entity, array type case): When checking bit packed arrays for
13325 the size being incorrect, check RM_Size, not Esize.
13326 (Freeze_Record_Type): Check for bad discriminated record convention
13327 (In_Exp_Body): Return true if the body is generated for a subprogram
13328 renaming, either an attribute renaming or a renaming as body.
13329 (Check_Itype): If the designated type of an anonymous access component
13330 is a non-protected subprogram type, indicate that it is frozen, to
13331 prevent out-of-scope freeze node at some subsequent call.
13332 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13333 only if the subprogram is neither imported nor exported, as well as the
13334 NCA descriptor class if the subprogram is exported.

13339 Gary Dismukes <dismukes@adacore.com>
13341 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13342 default initialization on an imported object, when there is no
13343 initialization call generated for it.
13344 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13347 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13348 Static_Elaboration_Desired.
13349 Remove pragma Thread_Body.
13350 Implement a new pragma No_Body
13351 Removes the Explicit_Overriding pragma
13352 Remove Optional_Overriding pragma
13353 (Prag): Deal with Universal_Aliasing.
13354 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13355 Pragma_CIL_Constructor): New names.
13357 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13358 uses the equivalent aggregate of a type must be treated as an implicit
13360 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13361 has none of the other categories.
13362 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13363 to apply Import to an object renaming declaration.
13365 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13366 from a C++ class should be declared as limited and that it will be
13367 considererd limited.
13368 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13369 should be declared as limited and that it will be considererd limited.
13370 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13371 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13372 (Analyze_Pragma): Deal with Universal_Aliasing.
13373 (Sig_Flags): Likewise.
13374 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13375 (Overflow_Checks_Unsuppressed): New flag.
13376 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13377 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13378 case of JVM or .NET targets, and compiling user code.
13379 Add debugging convenience routine rv
13381 2007-06-06 Robert Dewar <dewar@adacore.com>
13383 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13384 are interface type.
13385 (Build_Elementary_Input_Call): For floating-point use right type in the
13386 absence of strange size or stream size clauses.
13387 (Build_Elementary_Write_Call): Same fix
13388 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13389 set to value that does not match base type size.
13391 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13393 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13394 object of a limited type can be initialized with a call to a function
13395 that returns in place. If the limited type has unknown discriminants,
13396 and the underlying type is a constrained composite type, build an actual
13397 subtype from the function call, as is done for private types.
13398 (Side_Effect_Free): An expression that is the renaming of an object or
13399 whose prefix is the renaming of a object, is not side-effect free
13400 because it may be assigned through the renaming and its value must be

13924 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
13925 associated with dispatch tables is known at compile time.
13926 (Get_Value): If an association in a record aggregate has a box
13927 association, and the corresponding record component has a default
13928 expression, always copy the default expression, even when the

15225 build-in-place functions with result type with controlled parts.
15226 Remove no longer used entities.
15228 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
15229 longer needed, because the full type is now limited, and therefore a

15266 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
15267 causes the error message for the ambiguous "X'Access = Y'Access" and
15268 "X'Unrestricted_Access = Y'Access" and so forth to match.
15269 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
15270 now that anonymous access to protected operations have their own kind.

15276 attempt to derive from a synchronized tagged type.
15277 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15278 type, inherit the class-wide type already created, because it may
15279 already have been used in a self-referential anonymous access component.
15280 (Mentions_T): Recognize self-referential anonymous access components
15281 that use (a subtype of) the class-wide type of the enclosing type.

15334 (Compile): When compiling a predefined source, add -gnatpg
15335 as the second switch, after -c.
15336 (Compile_Sources): Allow compilation of Annex J renames without -a
15337 (Is_In_Object_Directory): Check if the ALI file is in the object

15340 gnatbind if the ALI file effectively exists.
15341 (Initialize): Add the directory where gnatmake is invoked in front of
15342 the path if it is invoked from a bin directory, even without directory

15367 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15368 when -gnatg is not specified.
15369 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15370 there is no need to generate always a record_definition_node in case
15371 of synchronized interface types.

15398 (Convert_Aggr_In_Allocator): If the allocator is for an access
15399 discriminant and the type is controlled. do not place on a finalization
15400 list at this point. The proper list will be determined from the

15420 parameter of the containing subprogram.
15421 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15422 under No_Dispatching_Calls restriction. During the semantic analysis
15423 we already notified such violation.
15424 (Tagged_Membership): Constant folding. There is no need to check
15425 the tag at run-time if the type of the right operand is non
15426 class-wide abstract.

15441 initialize most the TSD components by means of an aggregate.
15442 Modify the declaration of the object containing the TSD
15443 because we now expand code that has a higher level of abstraction.
15444 The TSD has a discriminant containing the Inheritance Depth Level,
15445 value that is used in the membership test but also to fix the size
15446 of the table of ancestors.
15447 (Expand_Interface_Conversion): Insert function body at the closest place
15448 to the conversion expression, to prevent access-before-elaboration
15449 errors in the backend.

15505 support concurrent types implementing interfaces.
15506 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15510 CW_Or_Controlled_Type whenever the issue is related to
15511 using or not the secondary stack.

15552 a protected version of an operation declared in the private part of
15553 a protected object, because they may be invoked through a callback.
15554 (Set_Privals): If the type of a private component is an anonymous access
15555 type, do not create a new itype for each protected body.
15556 If the body of a protected operation creates

15585 the unit being compiled is the one that contains the stub type.
15586 Change primitive operation name for the RACW associated with a RAS
15587 from Call to _Call so it cannot clash with any legal identifier.

15598 registering the receiving stubs at the end of the 'Stmts' list.
15599 (RCI_Package_Locator): Pass the new Version generic formal when
15600 instantiating a RCI_Locator package.
15601 (Build_From_Any_Function): To compute the High bound for an
15602 unconstrained array actual, we add the Low bound with the length.
15603 Thus we must convert the low bound and the length to an appropriate
15604 type before doing the sum.
15605 (Build_Subprogram_Receiving_Stubs, PolyORB):
15606 * Retrieve the extra formals parameters at the
15607 end of the parameter stream.
15608 * Use Move_Any_Value to write back out parameters
15609 after executing the request as it is more efficient

15629 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15630 typecode from the Etype. Therefore we retrieve the correct typecode
15631 with a call to Get_Any_Type.
15632 (Copy_Specification): Do controlling formal type substitution based on
15633 Is_Controlling_Formal flag, instead of caller-provided object type.
15634 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15635 a RACW primitive operation, we might get a subprogram declaration for an
15636 ancestor of the RACW designated type (not for the designated type
15637 itself), in the case where this operation is inherited. In this case we
15638 have no easy means of determining the original tagged type for which
15639 the primitive was declared, so instead we now rely on
15640 Copy_Specification to use the Is_Controlling_Formal flag to determine
15641 which formals require type substitution.

16103 unit, in which case the instance must be analyzed with the latest Ada
16104 mode. This setting must take place after analysis of the actuals,

16113 (Analyze_Formal_Package): For better error recovery, Add exception
16114 handler to catch Instantion_Error, which can be raised in
16115 Analyze_Associations

16118 Bob Duff <duff@adacore.com>
16119 Gary Dismukes <dismukes@adacore.com>
16121 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16122 prefix type is a discriminated subtype of the type of the formal.
16123 (Analyze_Allocator): Collect all coextensions regardless of the context.
16124 Whether they can be allocated statically is determined in exp_ch4.
16125 (Analyze_Selected_Component): If the prefix is a limited view and the
16126 non-limited view is available, use the non-limited one.
16127 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16128 therefore illegal), suggest a qualified expression rather than a type
16129 conversion, because a type conversion would be illegal in this context.
16130 (Anayze_Allocator): Trace recursively all nested allocators so that all
16131 coextensions are on the corresponding list for the root. Do no mark
16132 coextensions if the root allocator is within a declaration for a stack-
16133 allocated object, because the access discriminants will be allocated on
16135 (Analyze_Call): Remove restriction on calls to limited functions for the
16136 cases of generic actuals for formal objects, defaults for formal objects
16137 and defaults for record components.
16138 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16139 element list. Their expansion is delayed until the enclosing allocator
16140 is processed and its finalization list constructed.
16141 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16142 for an operation with the given name among the primitive operations of
16143 the corresponding record type.
16144 (Analyze_Selected_Component): If the prefix is a task type that
16145 implements an interface, and there is no entry with the given name,
16146 check whether there is another primitive operation (e.g. a function)
16148 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16149 properly the indexing of a function call written in prefix form, where
16150 the function returns an array type, and all parameters of the function
16151 except the first have defaults.
16152 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16153 the original operands, rather than relocating them, for efficiency and
16154 to work properly when an operand is overloaded.
16155 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16156 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16157 (Analyze_Selected_Component): If the prefix is a private extension, only
16158 scan the visible components, not those of the full view.
16159 (Try_Primitive_Operation): If the operation is a procedure, collect all
16160 possible interpretations, as for a function, because in the presence of
16161 classwide parameters several primitive operations of the type can match
16162 the given arguments.
16164 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16165 Robert Dewar <dewar@adacore.com>
16167 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

16172 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16173 Thomas Quinot <quinot@adacore.com>
16175 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16176 out of Analyze_Package_Declaration, because processing must be applied
16177 to package bodies as well, for deferred constants completed by pragmas.
16178 (Analyze_Package_Declaration): When the package declaration being
16179 analyzed does not require an explicit body, call Check_Completion.
16180 (May_Need_Implicit_Body): An implicit body is required when a package
16181 spec contains the declaration of a remote access-to-classwide type.
16182 (Analyze_Package_Body): If the package contains RACWs, append the
16183 pending subprogram bodies generated by exp_dist at the end of the body.
16184 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16185 Is_Abstract_Subprogram and Is_Abstract_Type.
16186 (Preserve_Full_Attributes): The full entity list is not an attribute
16187 that must be preserved from full to partial view.
16189 * sem_dist.adb (Add_RAS_Dereference_TSS):
16190 Change primitive name to _Call so it cannot clash with any legal
16191 identifier, and be special-cased in Check_Completion.
16192 Mark the full view of the designated type for the RACW associated with
16193 a RAS as Comes_From_Source to get proper view switching when installing
16194 private declarations.
16195 Provite a placeholder nested package body along with the nested spec
16196 to have a place for Append_RACW_Bodies to generate the calling stubs
16197 and stream attributes.
16199 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16200 Robert Dewar <dewar@adacore.com>
16202 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16203 that is a limited view, check the non-limited view if available.

16208 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16209 renaming as body when renamed entity is abstract.

16224 Javier Miranda <miranda@adacore.com>
16226 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16227 dereference of a local object R created as a reference to another
16228 object O, use the access level of O.
16229 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16230 rather than local Same_Formal_Type, to check whether protected operation
16231 overrides an inherited one.
16232 (Same_Formal_Type): New predicate, used when matching signatures of
16233 overriding synchronized operations, to handle the case when a formal
16234 has a type that is a generic actual.
16235 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16236 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16237 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16238 syntactic ambiguities involving indexing of function calls that return
16240 (Abstract_Interface_List): New subprogram that returns the list of
16241 abstract interfaces associated with a concurrent type or a
16242 concurrent record type.
16243 (Interface_Present_In_Parent): New subprogram used to check if a
16244 given type or some of its parents implement a given interface.
16245 (Collect_Abstract_Interfaces): Add support for concurrent types
16246 with interface types.
16247 (Has_Abstract_Interfaces): Add support for concurrent types with
16249 (Is_Parent): New subprogram that determines whether E1 is a parent
16250 of E2. For a concurrent type its parent is the first element of its
16251 list of interface types; for other types this function provides the
16252 same result than Is_Ancestor.
16253 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16254 (Collect_Synchronized_Interfaces): Removed because the subprogram
16255 Collect_Abstract_Interfaces provides this functionality.
16256 (Collect_Abstract_Interfaces): Minor update to give support to
16257 concurrent types and thus avoid undesired code duplication.
16258 (Get_Subprogram_Entity): Handle entry calls.
16259 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16261 (Enter_Name): Do not give -gnatwh hiding warning for record component

16277 can be an E_Return_Statement.
16278 (Is_Coextension): New flag for allocators.

16297 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16298 expression with a COMPOUND_EXPR including the call instead of emitting
16299 the call directly here.
16300 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16301 high bound is constant and the slice is empty. Tidy.
16302 (tree_transform, case N_Op_Not): Handle properly the case where the
16303 operation applies to a private type whose full view is a modular type.
16304 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16305 Address_Clause, use the associated Expression as the GNAT tree
16306 representing the choice value to ensure the corresponding GCC tree is
16307 of the proper kind.
16308 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16309 instead of just the operands, as the base GCC stabilize_reference does.
16310 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16311 requested; otherwise fail.
16312 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16317 implementation of UI_Div.
16318 (UI_Div): Reimplement as a call to UI_Div_Rem.
16319 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16320 remainder, avoiding the cost of a multiplication and a subtraction.
16321 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16322 provides both quotient and remainder in a single computation.
16323 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16324 functions for uint.
16325 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

16572 (mainly static expression evaluation).
16573 Reword some continuation messages
16574 Add some \\ sequences to continuation messages
16575 (Resolve_Call): Refine infinite recursion case. The test has been

16592 anonymous access types.
16593 (Valid_Conversion): For a conversion to a numeric type occurring in an
16594 instance or inlined body, no need to check that the operand type is
16595 numeric, since this has been checked during analysis of the template.

17183 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17184 assignments where the target subtype is unconstrained and the target
17185 object is a parameter or dereference (other aliased cases are known

17320 that has been derived from several abstract interfaces we must also

17350 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17351 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17352 an aliased prefix must be known to be constrained in order to use True
17353 for the attribute value, and now it's possible for some aliased views
17354 to be unconstrained.

17373 required to report the correct error message.
17374 (Expand_N_Subtype_Indication): Do validity checks on range
17375 (Clean_Task_Names): If an initialization procedure includes a call to

17385 Object_Declaration to the call.
17386 (Freeze_Type): When the designated type of an RACW was not frozen at the
17387 point where the RACW was declared, validate the primitive operations

17389 (Build_Initialization_Call,Expand_Record_Controller): Rename
17390 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because

17396 initialization of extension aggregates with abstract interfaces.
17397 (Build_Master_Renaming): Make public, for use by function declarations
17398 whose return type is an anonymous access type.
17399 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17400 Insert_List_Before_And_Analyze after the generation of the specs
17401 associated with null procedures.

17403 (Init_Secondary_Tags): Update documentation.
17404 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-

17417 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17418 immediate ancestor of a tagged type is an abstract interface type we
17419 must generate the specification of the predefined primitives associated
17420 with controlled types (because the dispatch table of the ancestor is
17421 null and hence these entries cannot be inherited). This is required to
17422 elaborate well the dispatch table.

17437 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17438 when the allocator is initialized by a build-in-place call, since the
17439 allocator is already rewritten as a reference to the function result,
17440 and this prevents an unwanted duplication of the function call.
17441 Add with and use of Exp_Ch6.
17442 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17443 is a call to build-in-place function and apply
17444 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17445 untagged designated types).
17446 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17447 optimization if source or target is biased.
17448 (Expand_N_Allocator): Add comments for case of an allocator within a
17449 function that returns an anonymous access type designating tasks.
17450 (Expand_N_Allocator): apply discriminant checks for access
17451 discriminants of anonymous access types (AI-402, AI-416)

17454 Robert Dewar <dewar@adacore.com>
17455 Gary Dismukes <dismukes@adacore.com>
17456 Ed Schonberg <schonberg@adacore.com>
17458 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17460 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17461 (Expand_N_Assignment_Statement): Call
17462 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17463 build-in-place function call. Currently, this can happen only for
17464 assignments that come from aggregates.
17465 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17466 in order to alleviate the upward compatibility introduced by AI-318.
17467 (Expand_N_Extended_Return_Statement): Add support for handling the
17468 return object as a build-in-place result.
17469 (Expand_Non_Function_Return): Implement simple return statements nested
17470 within an extended return.
17471 (Enable_New_Return_Processing): Turn on the new processing of return
17473 (Expand_Non_Function_Return): For a return within an extended return,
17474 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17475 (Expand_N_Extended_Return_Statement): Implement AI-318
17476 (Expand_Simple_Function_Return): Ditto.
17477 (Expand_N_If_Statement): Handle new -gnatwt warning
17478 (Expand_N_Case_Statement): Handle new -gnatwt warning
17479 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17480 a protected object.
17481 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17482 validity checking of assignments to elementary record components.
17483 (Expand_N_Return_Statement): return Class Wide types on the secondary
17484 stack independantly of their controlled status since with HIE runtimes,
17485 class wide types are not potentially controlled anymore.
17487 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17490 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17491 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17492 it expects a block, procedure, or task. The return statement will get
17493 turned into a block, and Expand_Cleanup_Actions will happen then.
17495 2006-10-31 Robert Dewar <dewar@adacore.com>
17496 Ed Schonberg <schonberg@adacore.com>
17497 Bob Duff <duff@adacore.com>
17498 Gary Dismukes <dismukes@adacore.com>
17500 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17502 (Expand_Inlined_Call): Tagged types are by-reference types, and
17503 therefore should be replaced by a renaming declaration in the expanded
17504 body, as is done for limited types.
17505 (Expand_Call): If this is a call to a function with dispatching access
17506 result, propagate tag from context.
17507 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17509 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17510 build-in-place when the right-hand side of an assignment is a
17511 build-in-place function call.
17512 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17513 of the explicit dereference of the allocator to the result subtype of
17514 the build-in-place function. This is needed to satisfy type checking
17515 in cases where the caller's return object is created by an allocator for
17516 a class-wide access type and the type named in the allocator is a
17518 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17519 conversion of the reference to the declared object to the result subtype
17520 of the build-in-place function. This is needed to satisfy type checking
17521 in cases where the declared object has a class-wide type. Also, in the
17522 class-wide case, change the type of the object entity to the specific
17523 result subtype of the function, to avoid passing a class-wide object
17524 without explicit initialization to the back end.
17525 (Register_Interface_DT_Entry): Moved outside the body of
17526 Freeze_Subprogram because this routine is now public; it is called from
17527 Check_Dispatching_Overriding to handle late overriding of abstract
17528 interface primitives.
17529 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17530 adding an implicit access actual on a call to a build-in-place function.
17531 (Expand_Actuals): Test for an actual parameter that is a call to a
17532 build-in-place function and apply
17533 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17534 (Is_Build_In_Place_Function): New function to determine whether an
17535 entity is a function whose calls should be handled as build-in-place.
17536 (Is_Build_In_Place_Function_Call): New function to determine whether an
17537 expression is a function call that should handled as build-in-place.
17538 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17539 calls to build-in-place functions as the initialization of an allocator.
17540 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17541 handling calls to build-in-place functions in contexts that do not
17542 involve init of a separate object (for example, actuals of subprogram
17544 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17545 handling calls to build-in-place functions as the initialization of an
17546 object declaration.
17547 (Detect_Infinite_Recursion): Add explicit parameter Process to
17548 instantiation of Traverse_Body to avoid unreferenced warning.
17549 (Check_Overriding_Inherited_Interfaces): Removed.
17550 (Register_Interface_DT_Entry): Code cleanup.
17551 (Register_Predefined_DT_Entry): Code cleanup.
17552 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17553 inlined statements if within a transient scope.
17554 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17555 formal parameters with occurrences of actuals in inlined body, establish
17556 visibility on the proper view of the actual's subtype for the body's
17558 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17559 compatibility mode and we have an imported CPP subprogram because
17560 for now we assume that imported CPP primitives correspond with
17561 objects whose constructor is in the CPP side (and therefore we
17562 don't need to generate code to register them in the dispatch table).
17563 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17564 aligned selected component.
17565 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17566 the actual of an in-mode parameter is a type conversion.
17567 (Expand_Actuals): If the call does not come from source and the actual
17568 is potentially misaligned, let gigi handle it rather than rejecting the
17569 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17570 Class Wide types as returning by reference independantly of their
17571 controlled status since with HIE runtimes class wide types are not
17572 potentially controlled anymore.
17574 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17576 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17577 references that are private components of the protected object.
17578 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17579 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17580 instantiation to deal with warnings.
17581 (Initialize_Protection): If expression for priority is non-static, use
17582 System_Priority as its expected type, in case the expression has not
17585 2006-10-31 Robert Dewar <dewar@adacore.com>
17587 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17588 initialization of Homonym_Len.
17589 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17590 names from fully qualified name. Fixes problem of duplicate
17591 external names differing only in the presence of such a block name.
17593 2006-10-31 Thomas Quinot <quinot@adacore.com>
17594 Pablo Oliveira <oliveira@adacore.com>
17596 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17597 subprogram Ids, even if they are not yet assigned.
17598 (Build_Subprogram_Id): It is now this function that will take care of
17599 calling Assign_Subprogram_Ids if necessary.
17600 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17601 should be done only once they are assigned.
17602 (Build_From_Any_Function, case of tagged types): Add missing call to
17604 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17605 type for an RACW type.
17606 (Add_RACW_Features): When processing an RACW declaration for which the
17607 designated type is already frozen, enforce E.2.2(14) rules immediately.
17608 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17609 special reordering of controlling formals.
17611 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17612 associated stub type for an RACW type.
17614 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17616 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17617 fixed-point operations in an integer context, i.e. as operands of a
17618 conversion to an integer type, indicate that result must be rounded.
17620 2006-10-31 Robert Dewar <dewar@adacore.com>
17622 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17623 cases, pass the encoding method, since it is now required by the run
17626 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17627 assumption that Str'First = 1.
17628 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17629 it on to the Value_Wide_Wide_Character call.
17630 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17631 properly handles a string of the form quote-encoded_wide_char-quote.
17633 * s-wchcnv.adb: Minor reformatting
17635 2006-10-31 Javier Miranda <miranda@adacore.com>
17637 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17638 run-time membership test to ensure that the constructed object
17639 implements the target abstract interface.
17641 2006-10-31 Robert Dewar <dewar@adacore.com>
17643 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17644 Machine_Attribute pragma internally to implement the user pragma.
17645 Add processing for pragma Interface so that it is now completely
17646 equivalent to pragma Import.
17648 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17649 so that it can be applied to all entities, including record components
17650 and enumeration literals.
17651 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17652 priority ranges are correct, verify compatibility against task
17653 dispatching and locking policies, and if everything is correct an entry
17654 is added to the table containing priority specific dispatching entries
17655 for this compilation unit.
17656 (Delay_Config_Pragma_Analyze): Delay processing
17657 Priority_Specific_Dispatching pragmas because when processing the
17658 pragma we need to access run-time data, such as the range of
17659 System.Any_Priority.
17660 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17661 Allow pragma Unreferenced as a context item
17662 Add pragma Preelaborable_Initialization
17663 (Analyze_Pragma, case Interface): Interface is extended so that it is
17664 now syntactically and semantically equivalent to Import.
17665 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17666 insertion characters.
17667 Add handling for Pragma_Wide_Character_Encoding
17668 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17669 never supercedes a real restriction, and that a real restriction
17670 always supercedes a warning.
17671 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17675 Ed Schonberg <schonberg@adacore.com>
17676 Robert Dewar <dewar@adacore.com>
17678 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17679 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17680 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17682 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17683 type of the function containing a return statement, because the
17684 Return_Type field was removed. We now use the Return_Applies_To field.
17686 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17687 (Build_Task_Image_Decl): If procedure is not called from an
17688 initialization procedure, indicate that function that builds task name
17689 uses the sec. stack. Otherwise the enclosing initialization procedure
17690 will carry the indication.
17691 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17692 N_Object_Declaration instead.
17693 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17694 conditional dead code killed, and change implementation accordingly.
17695 (Insert_Actions): Add N_Return_Object_Declaration case.
17696 Correct comment to mention N_Extension_Aggregate node.
17697 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17698 attempts to save information for global variables which cannot be
17700 (Get_Current_Value_Condition): Handle conditions the other way round
17701 (constant on left). Also handle right operand of AND and AND THEN
17702 (Set_Current_Value_Condition): Corresponding changes
17703 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17704 (Get_Current_Value_Condition): Handle simple boolean operands
17705 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17706 (Get_Current_Value_Condition): If the variable reference is within an
17707 if-statement, does not appear in the list of then_statments, and does
17708 not come from source, treat it as being at unknown location.
17709 (Get_Current_Value_Condition): Enhance to allow while statements to be
17710 processed as well as if statements.
17711 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17713 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17714 of loop. This is safe now that we fixed Kill_Current_Values.
17715 (OK_To_Do_Constant_Replacement): Check whether current scope is
17716 Standard, before examining outer scopes.
17718 2006-10-31 Vincent Celier <celier@adacore.com>
17720 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17721 When True, apply VMS treatment to children of packages A, G, I and S.
17724 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17726 2006-10-31 Robert Dewar <dewar@adacore.com>
17727 Ed Schonberg <schonberg@adacore.com>
17729 * freeze.adb: Add handling of Last_Assignment field
17730 (Warn_Overlay): Supply missing continuation marks in error msgs
17731 (Freeze_Entity): Add check for Preelaborable_Initialization
17733 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17735 * g-expect.adb: Add Warnings (Off) to prevent new warning
17737 * lib-xref.adb: Add handling of Last_Assignment field
17738 (Generate_Reference): Centralize handling of pragma Obsolescent here
17739 (Generate_Reference): Accept an implicit reference generated for a
17740 default in an instance.
17741 (Generate_Reference): Accept a reference for a node that is not in the
17742 main unit, if it is the generic body corresponding to an subprogram
17745 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17747 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17749 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17751 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17752 use clauses, to avoid messages on packages used to qualify, and also
17753 to avoid messages from obsolescent units.
17754 (Warn_On_Useless_Assignments): Don't generate messages for imported
17755 and exported variables.
17756 (Warn_On_Useless_Assignments): New procedure
17757 (Output_Obsolescent_Entity_Warnings): New procedure
17758 (Check_Code_Statement): New procedure
17760 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17761 Change name Is_Ada_2005 to Is_Ada_2005_Only
17762 (Last_Assignment): New field for useless assignment warning
17764 2006-10-31 Olivier Hainque <hainque@adacore.com>
17766 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17767 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17769 2006-10-31 Bob Duff <duff@adacore.com>
17770 Robert Dewar <dewar@adacore.com>
17771 Ed Schonberg <schonberg@adacore.com>
17773 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17774 Ada 95 mode, because it violates the new rules for AI-318.
17776 * g-awk.ads: Use overloaded subprograms in every case where we used to
17777 have a default of Current_Session. This makes the code closer to be
17778 correct for both Ada 95 and 2005.
17780 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17781 code, relying on the fact that the compiler generates a warning
17782 instead of an error in -gnatg mode.
17784 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17785 E_Return_Statement entity kind.
17786 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17788 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17789 report an error if the reserved word abstract has been previously found.
17790 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17792 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17793 parenthesized range attribute usage
17794 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17796 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17797 in the syntax for extended_return_statement. This is not in the latest
17798 RM, but the ARG is expected to issue an AI allowing this.
17799 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17800 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17801 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17802 P_Return_Statement): Parse the new syntax for extended_return_statement.
17804 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17805 Output_End_Missing): Add error-recovery code for the new
17806 extended_return_statement syntax; that is, the new E_Return entry on
17809 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17810 limited to nonlimited, because otherwise we violate the new Ada 2005
17811 rules about returning limited types in function Create_AST_Handler in
17814 * sem.adb (Analyze): Add cases for new node kinds
17815 N_Extended_Return_Statement and N_Return_Object_Declaration.
17817 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17818 type is in the same category as type of context before applying check,
17819 to prevent anomalies in instantiations.
17820 (Resolve_Aggregate): Remove test for limited components in aggregates.
17821 It's unnecessary in Ada 95, because if it has limited components, then
17822 it must be limited. It's wrong in Ada 2005, because limited aggregates
17824 (Resolve_Record_Aggregate): Move check for limited types later, because
17825 OK_For_Limited_Init requires its argument to have been resolved.
17826 (Get_Value): When copying the component default expression for a
17827 defaulted association in an aggregate, use the sloc of the aggregate
17828 and not that of the original expression, to prevent spurious
17829 elaboration errors, when the expression includes function calls.
17830 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17831 were missing. We also didn't handle qualified expressions. Now also
17832 allow function calls. Use new common routine OK_For_Limited_Init.
17833 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17834 with space can upper case letter).
17836 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17837 Has_Static_Discriminants flag
17838 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17839 type with discriminants.
17840 (Process_Range_Expr_In_Decl): Do validity checks on range
17841 (Build_Discriminant_Constraints): Use updated form of
17842 Denotes_Discriminant.
17843 (Process_Subtype): If the subtype is a private subtype whose full view
17844 is a concurrent subtype, introduce an itype reference to prevent scope
17846 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17847 Record_Type_Declaration): The functionality of the subprograms
17848 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17849 is now performed by a single routine.
17850 (Build_Derived_Record_Type): If the type definition includes an explicit
17851 indication of limitedness, then the type must be marked as limited here
17852 to ensure that any access discriminants will not be treated as having
17853 a local anonymous access type.
17854 (Check_Abstract_Overriding): Issue a detailed error message when an
17855 abstract subprogram was not overridden due to incorrect mode of its
17857 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17858 synchronized private extension declarations. Verify that the ancestor is
17859 a limited or synchronized interface or in the generic case, the ancestor
17860 is a tagged limited type or synchronized interface and all progenitors
17861 are either limited or synchronized interfaces.
17862 Derived_Type_Declaration): Check for presence of private extension when
17863 dealing with synchronized formal derived types.
17864 Process_Full_View): Enchance the check done on the usage of "limited" by
17865 testing whether the private view is synchronized.
17866 Verify that a synchronized private view is completed by a protected or
17868 (OK_For_Limited_Init_In_05): New function.
17869 (Analyze_Object_Declaration): Move check for limited types later,
17870 because OK_For_Limited_Init requires its argument to have been resolved.
17871 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17872 in order to alleviate the upward compatibility introduced by AI-318.
17873 (Constrain_Corresponding_Record): If the constraint is for a component
17874 subtype, mark the itype as frozen, to avoid out-of-scope references to
17875 discriminants in the back-end.
17876 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17877 this subprogram against wrong sources.
17878 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17879 discriminant of limited type completed with a protected type, when the
17880 discriminant is used to constrain a private component of the type, and
17881 expansion is disabled.
17882 (Find_Type_Of_Object): Do not treat a return subtype that is an
17883 anonymous subtype as a local_anonymous_type, because its accessibility
17884 level is the return type of the enclosing function.
17885 (Check_Initialization): In -gnatg mode, turn the error "cannot
17886 initialize entities of limited type" into a warning.
17887 (OK_For_Limited_Init): Return true for generated nodes, since it
17888 sometimes violates the legality rules.
17889 (Make_Incomplete_Declaration): If the type for which an incomplete
17890 declaration is created happens to be the currently visible entity,
17891 preserve the homonym chain when removing it from visibility.
17892 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17893 inherited subprograms.
17894 (Access_Definition): If this is an access to function that is the return
17895 type of an access_to_function definition, context is a type declaration
17896 and the scope of the anonymous type is the current one.
17897 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17898 incomplete subtype to the set of private dependents of the original
17900 (Constrain_Discriminated_Type): Emit an error message whenever an
17901 incomplete subtype is being constrained.
17902 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17903 corresponding subtype of the full view of the original incomplete type.
17904 (Check_Incomplete): Properly detect invalid usage of incomplete types

17918 Robert Dewar <dewar@adacore.com>
17920 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17921 handling executable extension manually and duplicating code.
17923 * make.adb: Implement new -S switch
17924 (Gnatmake): Use new function Osint.Executable_Name instead
17925 of handling executable extension manually.
17927 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17928 is specified, the executable name ends with this suffix.
17929 Take advantage of Osint.Executable_Name instead of duplicating code.
17931 * switch-m.adb: Recognize new gnatmake -S switch
17933 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17935 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17938 * makeusg.adb: Add line for gnatmake -S switch
17940 2006-10-31 Vincent Celier <celier@adacore.com>
17942 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17943 call it with -static-libgcc, as there are some platforms, such as
17944 Darwin, where one of these two switches is compulsory to link.
17946 2006-10-31 Vincent Celier <celier@adacore.com>
17948 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17949 instead of ADA_PROJECT_PATH, for the project path.
17950 (Gnatls): When displaying the project path directories, use host dir
17953 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17954 names in the project path, as absolute paths may correspond to
17955 multi-valued VMS logical names.
17957 2006-10-31 Vincent Celier <celier@adacore.com>
17959 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17960 absolute path name.
17961 (Locate_Regular_File): Ditto
17962 (Change_Dir): Remove, no longer used
17963 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17964 on Windows. Get it calling Get_Current_Dir.
17965 (OpenVMS): Remove imported boolean, no longer needed.
17966 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17967 (Pid_To_Integer): New function to convert a Process_Id to Integer
17969 2006-10-31 Thomas Quinot <quinot@adacore.com>

17972 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17974 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17977 2006-10-31 Robert Dewar <dewar@adacore.com>
17979 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
17980 initial letter o as a zero.

17986 2006-10-31 Robert Dewar <dewar@adacore.com>
17988 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17990 (Layout_Variant_Record): Retrieve the discriminants from the entity
17991 rather than from the type definition, because in the case of a full
17992 type for a private type we need to take the discriminants from the
17994 (Layout_Component_List): When applying the Max operator to variants with
17995 a nonstatic size, check whether either operand is static and scale that
17996 operand from bits to storage units before applying Max.
17997 (Layout_Type): In VMS, if a C-convention access type has no explicit
17998 size clause (and does not inherit one in the case of a derived type),
17999 then the size is reset to 32 from 64.
18001 2006-10-31 Vincent Celier <celier@adacore.com>
18003 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18004 its file has already been loaded, according to the unit being loaded,
18005 not to the current value of Multiple_Unit_Index.
18007 2006-10-31 Thomas Quinot <quinot@adacore.com>
18008 Eric Botcazou <ebotcazou@adacore.com>
18009 Arnaud Charlet <charlet@adacore.com>
18011 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18012 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18014 (a-except.o): Pass it to the compiler.
18015 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.

18033 2006-10-31 Vincent Celier <celier@adacore.com>
18035 * mlib-utl.adb (Initialized): Remove, no longer used
18036 (Initialize): Remove, no longer used
18037 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18038 if there is one, the archive indexer. Fail if the archive builder cannot
18040 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18043 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18045 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18046 Process_Body_Clauses): If the context of a body includes a use clause
18047 for P.Q then a with_clause for P in the same body is not redundant,
18048 even if the spec also has a with_clause on P.
18049 Add missing continuation mark to error msg
18050 (Build_Limited_Views): A limited view of a type is tagged if its
18051 declaration includes a record extension.
18052 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18053 node, even if the subunit has errors. This avoids malfunction by
18054 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18055 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18056 generation of obsolescent messages for with statements (cannot do
18057 this too early, or we cannot implement avoiding the messages in the
18058 case of obsolescent units withing obsolescent units).
18059 (Install_Siblings): If the with_clause is on a remote descendant of
18060 an ancestor of the current compilation unit, find whether there is
18061 a sibling child unit that is immediately visible.
18062 (Remove_Private_With_Clauses): New procedure, invoked after completing
18063 the analysis of the private part of a nested package, to remove from
18064 visibility the private with_clauses of the enclosing package
18066 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18067 now centralized in Generate_Reference.
18068 (Install_Limited_Context_Clauses): Remove superfluous error
18069 message associated with unlimited view visible through use
18070 and renamings. In addition, at the point in which the error
18071 is reported, we add the backslash to the text of the error
18072 to ensure that it is reported as a single error message.
18073 Use new // insertion for some continuation messages
18074 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18075 to create implicit with_clause for parent unit mentioned in original
18076 limited_with_clause.
18077 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18078 unit is a child unit. For ASIS queries.
18079 (Analyze_Subunit): If the subunit appears within a child unit, make all
18080 ancestor child units directly visible again.

18095 a formal object declaration with an access definition or a subtype mark
18096 with a null exclusion.
18097 (P_Generic_Association): Handle association with box, and others_choice
18098 with box, to support Ada 2005 partially parametrized formal packages.
18100 2006-10-31 Robert Dewar <dewar@adacore.com>
18101 Javier Miranda <miranda@adacore.com>
18103 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18104 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18105 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18106 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18107 private extensions.
18108 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18109 to P_Interface_Type_Definition.
18110 (P_Interface_Type_Definition): Addition of one formal to report an error
18111 if the reserved word abstract has been previously found.
18112 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18113 object renaming declaration with an access definition or subtype mark
18114 with a possible null exclusion.

18124 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
18125 unknown attribute in unknown package or in package that does not need
18127 (Parse_Package_Declaration): Do not issue warning for unknown package in
18130 2006-10-31 Vincent Celier <celier@adacore.com>
18132 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
18133 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18136 2006-10-31 Vincent Celier <celier@adacore.com>
18138 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18139 on VMS, change "__" to '.' before checking the name.
18140 (Record_Ada_Source): Always add the source file name in the list of
18141 of sources, even if it is not the first time, as it is for another
18143 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18144 dot, instead of replacing only the first '_'.
18146 * prj-part.adb (Parse): Convert project file path to canonical form
18148 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18149 extended, the project id of the project extending it is recorded in its
18150 data, even when it has already been processed as an imported project.
18152 2006-10-31 Robert Dewar <dewar@adacore.com>
18154 * repinfo.adb (List_Entities): Don't list entities from renaming
18157 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18158 Robert Dewar <dewar@adacore.com>
18160 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18161 only a restriction warning is active for the given restriction. This is
18162 desirable because we do not want to modify code in the case where only
18164 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18165 causes overriding of real restrictions.
18166 Take advantage of new No_Restrictions constant.
18168 * raise.h: (__gnat_set_globals): Change profile.
18170 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18172 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18175 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18176 Move all the entities in obsolete package System.PolyORB_Interface to
18177 System.Partition_Interface.
18178 (RE_Storage_Size): New function in System.Tasking.
18179 (RE_Get_Ceiling): New entity.
18180 (RE_Set_Ceiling): New entity.
18181 (RO_PE_Get_Ceiling): New entity.

18188 starting with a digit.
18190 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18191 Thomas Quinot <quinot@adacore.com>
18192 Javier Miranda <miranda@adacore.com>
18193 Gary Dismukes <dismukes@adacore.com>
18195 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18196 properly an attempt to apply Unchecked_Access to a protected operation.
18197 (OK_Self_Reference): New subprogram to check the legality of an access
18198 attribute whose prefix is the type of an enclosing aggregate.
18199 Generalizes previous mechanism to handle attribute references nested
18200 arbitrarily deep within the aggregate.
18201 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18202 can appear in an aggregate if this is a default-initialized aggregate
18203 for a self-referential type.
18204 (Resolve_Attribute, case Access): Ditto.
18205 Add support for new implementation defined attribute Stub_Type.
18206 (Eval_Attribute, case Attribute_Stub_Type): New case.
18207 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18208 (Stream_Attribute_Available): Implement using new subprogram from
18209 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18210 Has_Specified_Stream_Attribute flag.
18211 Disallow Storage_Size and Storage_Pool for access to subprogram
18212 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18213 access types of return subtypes in extended return statements. Remove
18214 accessibility checks on anonymous access types when Unchecked_Access is
18216 (Analyze_Attribute): Add support for the use of 'Class to convert
18217 a class-wide interface to a tagged type.
18218 Add support for the attribute Priority.
18219 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18220 whether the designated type is discriminated with a constrained partial
18221 view and require static matching in that case.
18222 Add local variable Des_Btyp. The Designated_Type
18223 of an access to incomplete subtype is either its non-limited view if
18224 coming from a limited with or its etype if regular incomplete subtype.
18226 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18227 Fix predicate to identify and allow cases of (expander-generated)
18228 references to tag of designated object of a RACW.
18229 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18230 non-static, and therefore cannot appear as a primary in a preelaborable
18232 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18233 Has_Read_Write_Attributes.
18234 (Has_Read_Write_Attributes): Reimplement in termes of
18235 Has_Stream_Attribute_Definition.
18236 (Missing_Read_Write_Attributes): When checking component types in a
18237 record, unconditionally call Missing_Read_Write_Attributes recursively
18238 (remove guard checking for Is_Record_Type / Is_Access_Type).
18240 2006-10-31 Robert Dewar <dewar@adacore.com>
18242 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18243 useless assignments here and conditionalize it on absence of exception
18245 (Analyze_Exception_Handlers): Small code reorganization of error
18246 detection code, for new handling of formal packages.
18248 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18249 Hristian Kirtchev <kirtchev@adacore.com>
18251 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18252 that has been constant-folded, preserve information of original tree,
18254 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18255 generated private extension declaration if the formal derived type is
18256 synchronized. Carry synchronized present over to the generated private
18258 (Validate_Derived_Type_Instance): Ensure that the actual of a
18259 synchronized formal derived type is a synchronized tagged type.
18260 (Instantiate_Formal_Package): When creating the instantiation used to
18261 validate the actual package of a formal declared without a box, check
18262 whether the formal itself depends on a prior actual.
18263 (Instantiate_Formal_Subprogram): Create new entities for the defining
18264 identifiers of the formals in the renaming declaration, for ASIS use.
18265 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18266 a renaming declaration or a subtype declaration for an actual in an
18267 instance, capture location information of declaration in generic, for
18269 (Instantiate_Formal_Package): Add comments on needed additional tests.
18270 AI-317 (partial parametrization) is fully implemented.
18271 (Validate_Private_Type_Instance): Add check for actual which
18272 must have preelaborable initialization
18273 Use new // insertion for some continuation messages
18274 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18275 Default_Expression. Add type retrieval when the declaration has an
18276 access definition. Update premature usage of incomplete type check.
18277 (Check_Access_Definition): New subsidiary routine. Check whether the
18278 current compilation version is Ada 05 and the supplied node has an
18280 (Instantiate object): Alphabetize local variables. Handle the creation
18281 of new renaming declarations with respect to the kind of definition
18282 used - either an access definition or a subtype mark. Guard against
18283 unnecessary error message in the context of anonymous access types after
18284 they have been resolved. Add check for required null exclusion in a
18285 formal object declaration.
18286 (Switch_View): A private subtype of a non-private type needs to be
18287 switched (the base type can have been switched without its private
18288 dependents because of the last branch of Check_Private_View.
18289 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18291 (Instantiate_Type): Emit an error message whenever a class-wide type of
18292 a tagged incomplete type is used as a generic actual.
18293 (Find_Actual_Type): Extend routine to handle a component type in a child
18294 unit that is imported from a formal package in a parent.
18295 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18296 agree on constrainedness, rather than checking against ultimate ancestor
18297 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18298 generic body, for navigation purposes.
18300 2006-10-31 Robert Dewar <dewar@adacore.com>
18301 Thomas Quinot <quinot@adacore.com>
18303 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18305 (New_Stream_Subprogram): When processing an attribute definition clause
18306 for a stream-oriented subprogram, record an entity node occurring at
18307 the point of clause to use for checking the visibility of the clause,
18308 as defined by 8.3(23) as amended by AI-195.
18309 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18310 New_Stream_Function and New_Stream_Procedure.
18311 (New_Stream_Function, New_Stream_Procedure): Removed.
18312 (Analyze_Attribute_Definition_Clause, case Address): Check new
18313 Alignment_Check check
18315 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18316 Javier Miranda <miranda@adacore.com>
18317 Robert Dewar <dewar@adacore.com>
18319 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18320 generate the same errors compiling under -gnatc.
18321 (Try_Object_Operation): If no candidate interpretation succeeds, but
18322 there is at least one primitive operation with the right name, report
18323 error in call rather than on a malformed selected component.
18324 (Analyze_Selected_Component): If the prefix is an incomplete type from
18325 a limited view, and the full view is available, use the full view to
18326 determine whether this is a prefixed call to a primitive operation.
18327 (Operator_Check): Verify that a candidate interpretation is a binary
18328 operation before checking the type of its second formal.
18329 (Analyze_Call): Add additional warnings for function call contexts not
18331 (Analyze_Allocator): Move the check for "initialization not allowed for
18332 limited types" after analyzing the expression. This is necessary,
18333 because OK_For_Limited_Init looks at the structure of the expression.
18334 Before analysis, we don't necessarily know what sort of expression it
18335 is. For example, we don't know whether F(X) is a function call or an
18336 indexed component; the former is legal in Ada 2005; the latter is not.
18337 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18338 were missing. We also didn't handle qualified expressions. Now also
18339 allow function calls. Use new common routine OK_For_Limited_Init.
18340 (Analyze_Type_Conversion): Do not perform some legality checks in an
18341 instance, because the error message will be redundant or spurious.
18342 (Analyze_Overloaded_Selected_Component): Do not do style check when
18343 setting an entity, since we do not know it is the right entity yet.
18344 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18345 (Analyze_Overloaded_Selected_Component): Same change
18346 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18347 since regular incomplete subtypes are transformed into corresponding
18348 subtypes of their full views.
18349 (Complete_Object_Operation): Treat name of transformed subprogram call
18350 as coming from source, for browsing purposes.
18351 (Try_Primitive_Operation): If formal is an access parameter, compare
18352 with base type of object to determine whether it is a primitive
18354 (Operator_Check): If no interpretation of the operator matches, check
18355 whether a use clause on any candidate might make the operation legal.
18356 (Try_Class_Wide_Operation): Check whether the first parameter is an
18357 access type whose designated type is class-wide.

18364 warn on infinite loops.
18365 Add \\ to some continuation messages
18366 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18367 (Process_Bounds): If the bounds are integer literals that result from
18368 constant-folding, and they carry a user-defined type, preserve that type
18369 rather than treating this as an integer range.
18370 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18371 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18372 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18373 left hand side of assignment.
18374 (Analyze_Assignment): Add suport to manage assigments to the attribute
18375 priority of a protected object.
18376 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18377 not just identifiers.
18378 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18379 or AND THEN for possible tracking.
18380 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18381 case of while loops so we can track values in the loop body.
18383 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18384 Hristian Kirtchev <kirtchev@adacore.com>
18385 Bob Duff <duff@adacore.com>
18387 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18388 procedure cannot be a protected operation (it is a basic_declaration,
18389 not a subprogram_declaration).
18390 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18391 Subp. Add logic for entry processing.
18392 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.

18404 Extra_Formals field.
18405 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18406 pass new parameters. Add support for adding the new extra access formal
18407 for functions whose calls are treated as build-in-place.
18408 (Analyze_A_Return_Statement): Correct casing in error message.
18409 Move Pop_Scope to after Analyze_Function_Return, because an extended
18410 return statement really is a full-fledged scope. Otherwise, visibility
18411 doesn't work right. Correct use of "\" for continuation messages.
18412 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18413 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18414 the node doesn't get properly marked as analyzed.
18415 (Analyze_Subprogram_Body): If subprogram is a function that returns
18416 an anonymous access type that denotes a task, build a Master Entity
18418 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18419 proper usage of null exclusion in a result definition.
18420 (Process_Formals): Code cleanup and new error message.

18427 (New_Overloaded_Entity): Do not remove the overriden entity from the
18428 homonym chain if it corresponds with an abstract interface primitive.
18429 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18430 call to the synthesized predicate Is_Incomplete_Type.
18431 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18433 (Analyze_Subprogram_Declaration): Check that abstract interface
18434 primitives are abstract or null.
18435 (Analyze_Subprogram_Specification): Remove previous check for abstract
18436 interfaces because it was not complete.
18437 (Has_Interface_Formals): Removed.

18442 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18443 of Analyze_Package_Body, to create Itype references for anonymous
18444 access types created in the package declaration, whose designated types
18445 may have only a limited view.
18446 (Analyze_Package_Specification): For the private part of a nested
18447 package, install private_with_clauses of enclosing compilation unit if
18448 we are in its visible part.
18449 (Declare_Inherited_Private_Subprograms): Complete barrier
18450 to ensure that the primitive operation has an alias to some parent
18451 primitive. This is now required because, after the changes done for the
18452 implementation of abstract interfaces, the contents of the list of
18453 primitives has entities whose alias attribute references entities of
18454 such list of primitives.
18455 (Analyze_Package_Specification): Simplify code that handles parent units
18456 of instances and formal packages.
18457 (Uninstall_Declarations): Check the convention consistency among
18458 primitive overriding operations of a tagged record type.

18472 as potentially use-visible.
18473 (Find_Type): Handle the case of an attribute reference for
18474 implementation defined attribute Stub_Type (simply let the analysis of
18475 the attribute reference rewrite it).
18476 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18477 type that appears in a Use_Type clause.
18478 (Analyze_Object_Renaming): Add support for renaming of the Priority
18480 (Find_Type): In Ada 2005, a task type can be used within its own body,
18481 when it appears in an access definition.
18482 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18483 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18484 in a formal object declaration or in a subtype declaration.
18485 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18486 (Check_Null_Exclusion): New local routine to
18487 Analyze_Subprogram_Renaming. Check whether the formals and return
18488 profile of a renamed subprogram have required null exclusions when
18489 their counterparts of the renaming already impose them.
18490 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18491 Determine whether an entity is inside a generic scope.
18492 (In_Open_Scope): First pass of documentation update.
18493 (Find_Expanded_Name): Add support for shadow entities associated with
18494 limited withed packages. This is required to handle nested packages.
18495 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18496 that makes a renaming of a limited withed package illegal.

18499 Ed Schonberg <schonberg@adacore.com>
18501 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18502 Check_Overriding_Indicator.
18503 (Analyze_Task_Definition): Ditto.
18504 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18505 (Check_Overriding_Indicator): To find overridden interface operation,
18506 examine only homonyms that have an explicit subprogram declaration, not
18507 inherited operations created by an unrelated type derivation.
18508 (Check_Overriding_Indicator): When checking for the presence of "null"
18509 in a procedure, ensure that the queried node is a procedure

18512 type when the formal is an access to variable.
18513 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

18523 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18524 inherited from an interface ancestor by another interface in the
18525 context of an instance as 'late'.

18527 of a call to a function that dispatches on access result.
18528 (Check_Dispatching_Operation): In case of late overriding of a primitive
18529 that covers abstract interface subprograms we register it in all the
18530 secondary dispatch tables associated with abstract interfaces.
18531 (Check_Dispatching_Call): Add check that a dispatching call is not made
18532 to a function with a controlling result of a limited type. This is a
18533 current implementation restriction.
18534 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18535 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18536 argument is an interface type that is a generic formal.
18537 (Is_Interface_Subprogram): Removed.
18538 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18539 operation, check the formals to handle the case in which it is
18540 associated with an abstract interface type.

18558 Javier Miranda <miranda@adacore.com>
18560 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18561 subprogram type to provide better diagnostics in case of ambiguity.
18562 (Covers): Handle coverage of formal and actual anonymous access types in
18563 the context of generic instantiation.
18564 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18565 abstract interface types; this is required to handle concurrent types
18566 with discriminants and abstract interface types.

18582 qualification from an expression. There are numerous places where this
18583 ought to be used, but we currently only deal properly with zero or one
18585 (In_Instance); The analysis of the actuals in the instantiation of a
18586 child unit is not within an instantiation, even though the parent
18587 instance is on the scope stack.

18590 (Check_Obsolescent): Removed
18591 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18609 (Has_Compatible_Alignment): New function
18610 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18611 objects to handle the Ada 2005 case, where aliasedness no longer implies

18666 statements are now pushed on the scope stack during semantic analysis.
18667 (Return_Object_Declarations): New field to support extended return
18669 (N_Extended_Return_Statement): New node for extended_return_statement
18671 (N_Return_Object_Declaration): New node for part of
18672 extended_return_statement nonterminal. Needed because all the necessary

18696 N_Object_Declaration instead. Implement the case for
18697 N_Extended_Return_Statement. Alphabetize the cases.
18698 Add cases for new nodes N_Extended_Return_Statement and
18699 N_Return_Object_Declaration. The code is not yet written.

19356 we must pass the work to the expander to generate the required code to
19357 evaluate the conversion at run-time.
19358 (Resolve_Equality_Op): Do not apply previous
19359 transformation if expansion is disasbled, to prevent anomalies when
19360 locating global references in a generic unit.

19662 condition handler as current in the compiled function.
19663 (body_with_handlers_p): New function. Tell whether a given sequence of

19698 other basic tools. The full version that includes the Ada 2005 stuff

19700 not want to cause bootstrap problems with compilers not recognizing

20035 Since we are changing the tree format anyway, also get rid of the
20036 junk obsolete Immediate_Errors flag.
20037 (Tree_Read): Change the way of reading Tree_Version_String - now we

20128 (Freeze_Record_Type): Do not generate the tables associated with
20129 timed and conditional dispatching calls through synchronized
20130 interfaces if compiling under No_Dispatching_Calls restriction.
20131 When compiling for Ada 2005, for a nonabstract
20132 type with a null extension, call Make_Controlling_Function_Wrappers
20133 and insert the wrapper function declarations and bodies (the latter
20134 being appended as freeze actions).
20135 (Predefined_Primitive_Bodies): Do not generate the bodies of the

20137 dispatching calls through synchronized interfaces if we are

20140 service is available before generating a call.
20141 (Make_Controlling_Function_Wrappers): New procedure.
20142 (Expand_N_Full_Type_Declaration): Create a class-wide master for

20144 tasks that implement such limited interface.
20145 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20146 procedure spec and body of the Offset_To_Top function that is generated
20147 when the parent of a type with discriminants has secondary dispatch
20149 (Init_Secondary_Tags): Handle the case in which the parent of the type
20150 containing secondary dispatch tables has discriminants to generate the
20151 correct arguments to call Set_Offset_To_Top.
20152 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20154 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20155 Add Wide_[Wide_]Expanded_Name.
20156 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20157 the same functionality of Get_Prim_Op_Address but applied to predefined
20158 primitive operations because the pointers to the predefined primitives
20159 are now saved in a separate table.
20160 (Parent_Size): Modified to get access to the separate table of primitive
20161 operations or the parent type.
20162 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20163 functionality of Set_Prim_Op_Address but applied to predefined primitive
20165 (Set_Signature): New subprogram used to store the signature of a DT.
20166 (Displace): If the Offset_To_Top value is not static then call the
20167 function generated by the expander to get such value; otherwise use
20168 the value stored in the table of interfaces.
20169 (Offset_To_Top): The type of the actual has been changed to Address to
20170 give the correct support to tagged types with discriminants. In this
20171 case this value is stored just immediately after the tag field.
20172 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20173 offset_to_top value is static and hence pass this value to the run-time
20174 to store it in the table of interfaces, or else if this value is dynamic
20175 and then pass to the run-time the address of a function that is
20176 generated by the expander to provide this value for each object of the
20179 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20180 (Default_Prim_Op_Count): New entity

20189 Make_Adjust_Call done for a newly-allocated object.
20191 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20192 in a subprogram are wrapped in a cleanup block, indicate that the
20193 subprogram contains an inner block with an exception handler.
20194 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20195 Adjust call is for a newly-allocated object. In that case we must not
20196 assume that the finalization list chain pointers are correct (since they
20197 come from a bit-for-bit copy of the original object's pointers) so if
20198 the attach level would otherwise be zero (no change), we set it to 4
20199 instead to cause the pointers to be reset to null.
20201 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20202 reset chain pointers to null.
20204 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20206 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20207 string, and the context requires a loop for the assignment (e.g.
20208 because the left-hand side is packed), generate a unique name for the
20209 temporary that holds the string, to prevent spurious name clashes.

20213 Robert Dewar <dewar@adacore.com>
20214 Gary Dismukes <dismukes@adacore.com>
20216 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20217 return unconstrained arrays.
20219 (Expand_Call): An indirect call through an access parameter of a
20220 protected operation is not a protected call.
20221 Add circuit to raise CE in Ada 2005 mode following call
20222 to Raise_Exception.
20223 (Register_DT_Entry): Do nothing if
20224 the run-time does not give support to abstract interfaces.
20225 (Freeze_Subprogram): In case of dispatching operations, do not generate
20226 code to register the operation in the dispatch table if the source
20227 is compiled with No_Dispatching_Calls.
20228 (Register_Predefined_DT_Entry): Generate code that calls the new
20229 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20230 Set_Prim_Op_Address.
20232 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20233 on array assignments if the right-hand side is a function call that has
20234 been inlined. Check is performed on the assignment in the block.
20235 (Process_Bounds): If bounds and range are overloaded, apply preference
20236 rule for root operations to disambiguate, and diagnose true ambiguity.
20237 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20238 a tag-indeterminate right-hand side even when Expander_Active is True.
20239 Needed to ensure that dispatching calls to T'Input are allowed and
20240 get the tag of the target class-wide object.
20242 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20243 an inherited primitive operation that already overrides several
20244 abstract interface primitives. For transitivity, the new entity must
20245 also override all the abstract interface primitives covered by the
20246 inherited overriden primitive.
20247 Emit warning if new entity differs from homograph in same scope only in
20248 that one has an access parameter and the other one has a parameter of
20249 a general access type with the same designated type, at the same
20250 position in the signature.
20251 (Make_Inequality_Operator): Use source locations of parameters and
20252 subtype marks from corresponding equality operator when creating the
20253 tree structure for the implicit declaration of "/=". This does not
20254 change anything in behaviour except that the decoration of the
20255 components of the subtree created for "/=" allows ASIS to get the
20256 string images of the corresponding identifiers.
20257 (Analyze_Return_Statement): Remove '!' in warning message.
20258 (Check_Statement_Sequence): Likewise.
20259 (Analyze_Subprogram_Body): For an access parameter whose designated type
20260 is an incomplete type imported through a limited_with clause, use the
20261 type of the corresponding formal in the body.
20262 (Check_Returns): Implicit return in No_Return procedure now raises
20263 Program_Error with a compile time warning, instead of beging illegal.
20264 (Has_Single_Return): Function returning unconstrained type cannot be
20265 inlined if expression in unique return statement is not an identifier.
20266 (Build_Body_To_Inline): It is possible to inline a function call that
20267 returns an unconstrained type if all return statements in the function
20268 return the same local variable. Subsidiary procedure Has_Single_Return
20269 verifies that the body conforms to this restriction.
20271 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20272 same type, and one of them is of an anonymous access type, convert
20273 the other operand to it, so that this is a valid binary operation for
20275 (Resolve_Type_Conversion): Handle subtypes of protected types and
20276 task types when accessing to the corresponding record type.
20277 (Resolve_Allocator): Add '\' in 2-line warning message.
20278 Remove '!' in warning message.
20279 (Resolve_Call): Add '\' in 2-line warning message.
20280 (Valid_Conversion): Likewise.
20281 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20282 resulting type may be an access type with an implicit dereference.
20283 Obtain the proper component from the designated type.
20284 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20285 given by an expanded name with prefix Standard, when the operands are
20286 of an anonymous access type.
20287 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20288 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20289 prefix of the expression is not of an incomplete type. Allows full
20290 diagnoses of all semantic errors.
20291 (Resolve_Actuals): If the actual is an allocator whose directly
20292 designated type is a class-wide interface we build an anonymous
20293 access type to use it as the type of the allocator. Later, when
20294 the subprogram call is expanded, if the interface has a secondary
20295 dispatch table the expander will add a type conversion to force
20296 the displacement of the pointer.
20297 (Resolve_Call): If a function that returns an unconstrained type is
20298 marked Inlined_Always and inlined, the call will be inlined and does
20299 not require the creation of a transient scope.
20300 (Check_Direct_Boolean_Op): Removed
20301 (Resolve_Comparison_Op): Remove call to above
20302 (Resolve_Equality_Op): Remove call to above
20303 (Resolve_Logical_Op): Inline above, since this is only call.
20304 (Valid_Conversion): Handle properly conversions between arrays of
20305 convertible anonymous access types.
20308 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20309 the literal in an unchecked conversion, because GCC 4.x needs a static
20310 value for a string bound.
20312 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20313 Hristian Kirtchev <kirtchev@adacore.com>
20315 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20316 components of the corresponding record, take into account component
20317 definitions that are access definitions.
20318 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20319 procedure is not considered a dispatching call and will be expanded
20322 2006-02-13 Javier Miranda <miranda@adacore.com>
20324 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20325 controlling argument of the dispatching call is an abstract interface
20326 class-wide type then we use it directly.
20327 Check No_Dispatching_Calls restriction.
20328 (Default_Prim_Op_Position): Remove the code that looks for the last
20329 entity in the list of aliased subprograms. This code was wrong in
20331 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20332 when the source is compiled with the No_Dispatching_Calls restriction.
20333 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20334 if we are compiling with restriction No_Dispatching_Calls.
20335 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20336 subprograms if we are compiling under No_Dispatching_Calls restriction.
20337 (Make_DT): Generate a dispatch table with a single dummy entry if
20338 we are compiling with the No_Dispatching_Calls restriction. In
20339 addition, in this case we don't generate code that calls to the
20340 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20341 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20342 of this subprogram if compiling with the No_Dispatching_Calls
20344 (Expand_Type_Conversion): Instead of using the actual parameter,
20345 the argument passed as parameter to the conversion function was
20346 erroneously referenced by the expander.
20347 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20348 Set_Predefined_Primitive_Op_Address and Set_Signature.
20349 (Expand_Dispatching_Call): Generate call to
20350 Get_Predefined_Prim_Op_Address for predefined primitives.
20351 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20352 predefined primitives.
20353 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20354 primitives we reserve one dummy entry to ensure that the tag does not
20355 point to some memory that is associated with some other object. In
20356 addition, remove all the old code that generated the assignments
20357 associated with the signature of the dispatch table and replace them
20358 by a call to the new subprogram Set_Signature.
20359 (Set_All_DT_Position): Change the algorithm because now we have a
20360 separate dispatch table associated with predefined primitive operations.
20361 (Expand_Interface_Conversion): In case of non-static offset_to_top
20362 add explicit dereference to get access to the object after the call
20363 to displace the pointer to the object.
20364 (Expand_Interface_Thunk): Modify the generation of the actual used
20365 in the calls to the run-time function Offset_To_Top to fulfil its
20367 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20369 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20371 * exp_dist.adb (Copy_Specification): For access parameters, copy
20372 Null_Exclusion flag, which will have been set for stream subprograms
20375 2006-02-13 Pascal Obry <obry@adacore.com>
20377 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20378 previous implementation was using the C runtime spawnve routine but
20379 the corresponding wait was using directly the Win32 API. This was
20380 causing some times a lock when waiting for an event using
20381 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20382 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20383 API fixes this problem.
20385 2006-02-13 Robert Dewar <dewar@adacore.com>
20387 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20395 array reference that is an explicit dereference, mark the converted
20396 (packed) array reference as analyzed to prevent a forthcoming
20397 reanalysis from resetting its type to the original (non-packed) array
20400 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20401 Javier Miranda <miranda@adacore.com>
20402 Eric Botcazou <ebotcazou@adacore.com>
20404 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20405 Is_Predefined_Primitive_Operation): When
20406 searching for the predefined equality operator, verify that operands
20407 have the same type.
20408 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20409 for the last entity in the list of aliased subprograms. This code
20410 was wrong in case of renamings.
20411 (Set_Renamed_Subprogram): New procedure
20412 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20413 Exp_Type constant computed when entering this subprogram.
20414 (Known_Null): New function
20415 (OK_To_Do_Constant_Replacement): New function
20416 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20417 (Side_Effect_Free): An attribute reference 'Input is not free of
20418 side effect, unlike other attributes that are functions. (from code
20420 (Remove_Side_Effects): Expressions that involve packed arrays or records
20421 are copied at the point of reference, and therefore must be marked as
20422 renamings of objects.
20423 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20424 not a dispatching operation.
20427 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20428 elementary types in all cases.
20430 2006-02-13 Javier Miranda <miranda@adacore.com>
20432 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20433 task types when accessing to the corresponding record type.
20434 Remove '!' in warning message.
20436 2006-02-13 Olivier Hainque <hainque@adacore.com>
20438 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20439 to avoid useless and space inefficient overalignments on targets where
20440 Max_Alignment is larger than 16.
20442 2006-02-13 Pascal Obry <obry@adacore.com>
20444 * g-catiio.adb (Sec_Number): New type used to compute the number of
20445 seconds since 1-1-1970.
20446 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20447 negative numbers (years, months...) it is better to have a Natural here.
20449 (Image) [Number]: Change parameter from Long_Integer to Number.
20450 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20451 overflow for dates past year 2038.
20453 2006-02-13 Matthew Heaney <heaney@adacore.com>
20455 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20458 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20460 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20462 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20463 finalization can occur normally.
20465 2006-02-13 Vincent Celier <celier@adacore.com>
20467 * gnatcmd.adb (Rules_Switches): New table
20468 (Add_To_Rules_Switches): New procedure
20469 (GNATCmd): For command CHECK, put all options following "-rules" in the
20470 Rules_Switches table. Append these -rules switches after the -cargs
20473 2006-02-13 Robert Dewar <dewar@adacore.com>
20475 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20476 These two cases were generating incorrect output, and if this unit
20477 was built with checks on, generated a discriminant mismatch constraint
20480 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20481 Robert Dewar <dewar@adacore.com>
20483 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20484 view is an array type, indicate the component type as well, for
20485 navigation purposes.
20486 (Generate_Reference): Don't consider array ref on LHS to be a case
20487 of violating pragma Unreferenced.
20488 Do not give Ada 2005 warning except on real reference.
20490 2006-02-13 Vincent Celier <celier@adacore.com>
20492 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20493 main source, add switch -mdebug-main=_ada_ so that the executable can
20494 be debugged by the standard VMS debugger.
20495 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20496 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20497 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20498 of the last source, as the binding and linking phases are never
20500 Set all executable obsolete when rebuilding a library.
20502 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20505 2006-02-13 Javier Miranda <miranda@adacore.com>
20508 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20509 code to improve the error message reported when the program has
20510 declarations of abstract interface types and it is not compiled with
20511 the -gnat05 switch.
20512 (P_Access_Definition): Reorganize the code to improve the error
20513 message reported when the new Ada 2005 syntax for anonymous
20514 access types is used and the program is not compiled with the
20517 2006-02-13 Robert Dewar <dewar@adacore.com>
20519 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,

20523 2006-02-13 Javier Miranda <miranda@adacore.com>
20525 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser

20528 2006-02-13 Vincent Celier <celier@adacore.com>
20530 * prj.adb (Reset): Initialize the first element of table Namings with
20531 the standard naming data.
20533 2006-02-13 Vincent Celier <celier@adacore.com>
20535 * prj.ads (Error_Warning): New enumeration type
20537 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20538 unknown, use the location of the project to report the error.

20552 Call Recursive_Check with parameter When_No_Sources.
20553 (Recursive_Check): New parameter When_No_Sources. Call itself and
20554 Prj.Nmsc.Check with parameter When_No_Sources.
20555 (Process): New parameter When_No_Sources. Call Check with parameter
20557 (Copy_Package_Declarations): New procedure to copy renamed parameters
20558 and setting the location of the declared attributes to the location
20559 of the renamed package.
20560 (Process_Declarative_Items): Call Copy_Package_Declarations for renamed

20565 * prj-makr.adb (Make): Preserve the comments from the original project
20567 When removing nodes (attributes Source_Dirs, Source_Files,
20568 Source_List_File and package Naming), save the comments and attach the
20569 saved comments to the newly created nodes.
20570 Do not add a with clause for the naming package if one already exists.

20582 (Check_Dispatching_Operation): Do not generate code to register the
20583 operation in the dispatch table if the source is compiled with
20584 restriction No_Dispatching_Calls.

20586 No_Return procedure with procedure that is not No_Return
20587 (Check_Dispatching_Call): Suppress the check for an abstract operation
20588 when the original node of an actual is a tag-indeterminate attribute
20589 call, since the attribute, which must be 'Input, can never be abstract.
20590 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20591 call to the Input attribute (even when rewritten).
20592 (Propagate_Tag): Augment comment to indicate the possibility of a call
20593 to an Input attribute.
20595 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20596 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20598 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20599 No_Wide_Characters is no longer partition-wide
20600 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
20603 2006-02-13 Douglas Rupp <rupp@adacore.com>
20605 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20607 2006-02-13 Javier Miranda <miranda@adacore.com>
20609 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20610 handles default-initialized components to keep separate the management
20611 of this feature but also avoid the unrequired resolution and
20612 expansion of components that do not have partially initialized
20614 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20615 (Check_Bounds): Likewise.
20616 (Check_Length): Likewise.
20618 2006-02-13 Javier Miranda <miranda@adacore.com>
20619 Ed Schonberg <schonberg@adacore.com>
20621 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20622 abstract interface type call analyze_and_resolve to expand the type
20623 conversion into the corresponding displacement of the
20624 reference to the base of the object.
20625 (Eval_Attribute, case Width): For systems where IEEE extended precision
20626 is supported, the maximum exponent occupies 4 decimal digits.
20627 (Accessibility_Message): Add '\' in 2-line warning message.
20628 (Resolve_Attribute): Likewise.
20629 (case Attribute_Access): Significantly revise checks
20630 for illegal access-to-subprogram Access attributes to properly enforce
20631 the rules of 3.10.2(32/2).
20632 Diagnose use of current instance with an illegal attribute.
20634 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20636 (Enclosing_Generic_Unit): New function to return a node's innermost
20637 enclosing generic declaration node.
20638 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20639 (Type_Access_Level): The accessibility level of anonymous acccess types
20640 associated with discriminants is that of the current instance of the
20641 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20642 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20643 (Kill_Current_Values_For_Entity): New function
20644 (Enter_Name): Change formal type to Entity_Id
20646 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20647 Ed Schonberg <schonberg@adacore.com>
20648 Gary Dismukes <dismukes@adacore.com>
20650 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20651 Analyze_Compilation_Unit.
20652 Detect and warn on redundant with clauses detected in a package spec
20653 and/or body when -gnatwr is used.
20654 (Analyze_Context): Analyze config pragmas before other items
20655 (Install_Context_Items): Don't analyze config pragmas here
20656 (Install_Limited_Withed_Unit): Set limited entity of package in
20657 with_clause so that cross-reference information or warning messages on
20658 unused packages can be properly generated
20659 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20660 has Error_Posted set. Prevent infinite loops in illegal programs.
20661 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20662 to the point of the error test requiring the current unit to be private.
20663 This ensures that private with clauses are not exempted from the basic
20664 checking for being a descendant of the same library unit parent as a
20665 withed private descendant unit.
20666 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20667 handle private with clauses properly, as well as to account for cases
20668 where the withed unit is a public descendant of a private ancestor
20669 (in which case the current unit must be a descendant of the private
20670 ancestor's parent). The spec comments were updated accordingly. Also,
20671 the old error message in this subprogram was replaced with error
20672 messages that mirror the errors tested and reported by
20673 Check_Private_Child_Unit.
20674 Parameter and variable names improved for readability.
20675 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20676 private as the precondition for calling
20677 Check_Private_Limited_Withed_Unit since that subprogram has been
20678 revised to test public units as well as private units.

20685 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20686 that Scope_Stack.First = 1.
20687 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20688 were not always properly handled previously.
20689 (Formal_Entity): Complete rewrite, to handle properly some complex case
20690 with multiple levels of parametrization by formal packages.
20691 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20692 to the corresponding derived type declaration for proper semantics.
20694 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20695 (Check_Component): Enforce restriction on components of
20696 unchecked_unions: a component in a variant cannot contain tasks or
20698 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20700 Add pragma Ada_2005 (synonym for Ada_05)
20701 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20702 were not always properly handled previously.
20703 Document that pragma Propagate_Exceptions has no effect
20704 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20705 (Set_Convention_From_Pragma): Check that if a convention is
20706 specified for a dispatching operation, then it must be
20707 consistent with the existing convention for the operation.
20708 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20709 longer required to specify an vtable-ptr component in the record. For
20710 compatibility reasons we leave the support for the previous definition.
20711 (Analyze_Pragma, case No_Return): Allow multiple arguments
20713 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20714 non-overrideen inherited operation with a controlling result as
20715 illegal only its implicit declaration comes from the derived type
20716 declaration of its result's type.
20717 (Check_Possible_Deferred_Completion): Relocate the object definition
20718 node of the subtype indication of a deferred constant completion rather
20719 than directly analyzing it. The analysis of the generated subtype will
20720 correctly decorate the GNAT tree.
20721 (Record_Type_Declaration): Check whether this is a declaration for a
20722 limited derived record before analyzing components.
20723 (Analyze_Component_Declaration): Diagnose record types not explicitly
20724 declared limited when a component has a limited type.
20725 (Build_Derived_Record_Type): Code reorganization to check if some of
20726 the inherited subprograms of a tagged type cover interface primitives.
20727 This check was missing in case of a full-type associated with a private
20729 (Constant_Redeclaration): Check that the subtypes of the partial and the
20730 full view of a constrained deferred constant statically match.
20731 (Mentions_T): A reference to the current type in an anonymous access
20732 component declaration must be an entity name.
20733 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20734 class_wide type to refer to full type, not to the incomplete one.
20735 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20736 available. Required to give support to the certified run-time.
20737 (Analyze_Component_Declaration): In case of anonymous access components
20738 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20739 (Process_Discriminants): For an access discriminant, use the
20740 discriminant specification as the associated_node_for_itype, to
20741 simplify accessibility checks.
20743 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20744 Javier Miranda <miranda@adacore.com>
20746 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20747 abstract interpretations on an operator, remove interpretations that
20748 yield Address or a type derived from it, if one of the operands is an
20750 (Try_Object_Operation.Try_Primitive_Operation,
20751 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20752 location when creating the new reference to a primitive or class-wide
20753 operation as a part of rewriting a subprogram call.
20754 (Try_Primitive_Operations): If context requires a function, collect all
20755 interpretations after the first match, because there may be primitive
20756 operations of the same type with the same profile and different return
20757 types. From code reading.
20758 (Try_Primitive_Operation): Use the node kind to choose the proper
20759 operation when a function and a procedure have the same parameter
20761 (Complete_Object_Operation): If formal is an access parameter and prefix
20762 is an object, rewrite as an Access reference, to match signature of
20763 primitive operation.
20764 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20765 by an expanded name with prefix Standard, when the operands are of an
20766 anonymous access type.
20767 (Remove_Abstract_Operations): If the operation is abstract because it is
20768 inherited by a user-defined type derived from Address, remove it as
20769 well from the set of candidate interpretations of an overloaded node.
20770 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20773 2006-02-13 Bob Duff <duff@adacore.com>
20775 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20776 redundant use clauses.
20777 In particular, if the scope of two use clauses overlaps, but one is not
20778 entirely included in the other, we should not warn. This can happen
20779 with nested packages.
20780 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20781 reported errors. The bug was reported when the compiler was built
20782 with assertions enabled.
20783 (Find_Type): If the node is a 'Class reference and the prefix is a
20784 synchronized type without a corresponding record, return the type
20787 2006-02-13 Javier Miranda <miranda@adacore.com>
20789 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20790 if this is the full-declaration associated with a private declaration
20791 that implement interfaces, then the private type declaration must be
20793 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20794 as aliased. The use of the 'access attribute is not available for such
20795 object (for this purpose the object should be explicitly marked as
20796 aliased, but being an anonymous type this is not possible).
20798 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20799 Robert Dewar <dewar@adacore.com>
20801 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20802 compilation unit is an elaboration scope.
20803 (Add_Task_Proc): Add '\' in 2-line warning message.
20804 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20806 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20807 Javier Miranda <miranda@adacore.com>
20809 * sem_type.adb (Write_Overloads): Improve display of candidate
20811 (Add_One_Interp): Do not add to the list of interpretations aliased
20812 entities corresponding with an abstract interface type that is an
20813 immediate ancestor of a tagged type; otherwise we have a dummy
20814 conflict between this entity and the aliased entity.
20815 (Disambiguate): The predefined equality on universal_access is not
20816 usable if there is a user-defined equality with the proper signature,
20817 declared in the same declarative part as the designated type.
20818 (Find_Unique_Type): The universal_access equality operator defined under
20819 AI-230 does not cover pool specific access types.
20820 (Covers): If one of the types is a generic actual subtype, check whether
20821 it matches the partial view of the other type.
20823 2006-02-13 Thomas Quinot <quinot@adacore.com>
20825 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20826 line. This is necessary to allow In_Extended_Main_Unit to provide
20827 correct results for itypes while writing out expanded source.
20828 (Close_File): No need to update the source_index_table here since it's
20829 now done for each line.
20831 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20832 Robert Dewar <dewar@adacore.com>
20834 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20835 preserve the source unit where the itype is declared, and prevent a
20837 (Note_Implicit_Run_Time_Call): New procedure
20838 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20841 * sprint.ads: Document use of $ for implicit run time routine call
20843 2006-02-13 Quentin Ochem <ochem@adacore.com>
20845 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20848 2006-02-13 Bob Duff <duff@adacore.com>
20850 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20851 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20852 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20853 raise Constraint_Error.
20855 * s-vallli.adb (Scan_Long_Long_Integer): Call
20856 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20857 do not scan leading blanks and sign twice.
20858 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20859 raise Constraint_Error.
20861 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20862 Scan_Long_Long_Unsigned): Split out most of the processing from
20863 Scan_Long_Long_Unsigned out into
20864 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20865 This prevents scanning leading blanks and sign twice.
20866 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20869 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20870 out most of the processing from Scan_Unsigned out into
20871 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20872 This prevents scanning leading blanks and sign twice.
20874 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20875 use with Modular'Value attribute.
20876 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20879 2006-02-13 Robert Dewar <dewar@adacore.com>
20881 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20883 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
20885 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
20886 (PPC VxWorks): Likewise.
20887 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20888 (forced_callee): Make non-inlinable and non-pure.
20889 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

21004 ({declaraction},Delete_Binder_Generated_Files,{initialization}): Change
21005 Ada bind file prefix on VMS from b$ to b__.
21007 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in

21031 (../../vxaddr2line): gnatlink with targext.o.
21032 (TOOLS_LIBS): Move targext.o to precede libgnat.
21033 (init.o, initialize.o): Minor clean up in dependencies.

21074 * a-taster.ads, a-taster.adb: New files.
21076 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21077 link to the version that does nothing. This way the task termination
21078 routine is not executed twice for the environment task when finishing
21079 because of an unhandled exception.
21081 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21082 handler because of an unhandled exception.
21084 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21085 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21087 * s-finimp.adb (initialization code): Modify the soft link for the
21088 finalization of the global list instead of Adafinal.
21090 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21091 non-tasking version of the soft link for task termination. We do
21092 nothing since if we are using the non-tasking version it
21093 means that the task termination functionality is not used.
21094 (Null_Finalize_Global_List): Add this null version for the procedure
21095 in charge of finalizing the global list for controlled objects.
21096 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21097 instead for handling run-time termination in a more flexible way.
21098 (Adafinal_NT): This new procedure will take care of finalizing the
21099 global list for controlled objects if needed, but no tasking
21102 * s-tarest.adb (Task_Lock): Do not try to lock again the
21103 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21104 some run-time operations.
21105 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21106 until all nested locks have been released.
21107 (Task_Wrapper): Call the fall-back task termination handler. It
21108 applies to all tasks but the environment task.
21109 (Finalize_Global_Tasks): Add the call for the task termination
21110 procedure for the environment task.
21111 (Task_Wrapper): suppress warnings around declaration of
21112 Secondary_Stack_Address.
21114 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21115 moved to the Common_ATCB record.
21116 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21117 Common_ATCB record.
21118 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21119 Common_ATCB record.
21121 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21122 Fall_Back_Handler, and Specific_Handler.
21124 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21125 defined in Ada.Task_Termination, to avoid circular dependencies.
21126 (Termination_Handler): Redefine this type here, alredy defined in
21127 Ada.Task_Termination, for avoiding circular dependencies.
21128 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21129 for storing task termination handlers. In addition,
21130 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21131 Common_ATCB because it is used by both the regular and the restricted
21133 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21134 Common_ATCB because it is used by both the regular and the restricted
21136 (Common_ATCB): Added a dynamic task analyzer field.
21138 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21139 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21140 (Task_Wrapper): Call the task termination handler. It applies to all
21141 tasks but the environment task.
21142 (Finalize_Global_Tasks): Call the task termination procedure for the
21143 environment task. The call to Finalize_Global_List is now performed
21144 using the soft links mechanism.
21145 (Task_Wrapper): added dynamic stack analysis.
21147 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21148 potentially blocking operations has been moved from
21149 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21150 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21151 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21152 this run-time check.
21154 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21155 of task termination procedure.
21156 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21157 link for the task termination procedure.
21159 * bindusg.adb: (Bindusg): Added documentation for -u option.
21161 * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.
21162 (Get_Main_C): Add handling of dynamic stack analysis.
21163 (Gen_Output_File_C): Add external functions for dynamic stack analysis.

21173 (Standart_Output): new subprogram
21174 (Set_Output): new subprogram
21175 (Put): now uses the value of Current_Out to know if the output has to be
21176 send to stderr or stdout.
21178 * s-stausa.ads: Complete implementation.
21180 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21182 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21183 list of Ada 05 files.
21184 (GNAT Library Units): Add AltiVec files.

21187 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21188 g-alvety.ads, g-alvevi.ads: New files providing altivec API.

21193 file_name is empty.
21195 2005-12-09 Javier Miranda <miranda@adacore.com>
21196 Hristian Kirtchev <kirtchev@adacore.com>
21198 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21199 to the specification because the frontend generates code that uses this
21201 (Set_Interface_Table): Add missing assertion.
21202 Update documentation describing the run-time structure.
21203 (Displace): New subprogram that displaces the pointer to the object
21204 to reference one of its secondary dispatch tables.
21205 (IW_Membership): Modified to use the new table of interfaces.
21206 (Inherit_TSD): Modified to use the new table of interfaces.
21207 (Register_Interface_Tag): Use the additional formal to fill the
21208 contents of the new table of interfaces.
21209 (Set_Interface_Table): New subprogram that stores in the TSD the
21210 pointer to the table of interfaces.

21224 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21225 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21226 record component containing the tag of the secondary dispatch table we
21227 have to use the Offset_To_Top run-time function to get this information;
21228 otherwise if the pointer to the base of the object has been displace
21229 we get a wrong value if we use the 'position attribute.
21231 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21232 all the calls to Expand_Interface_Thunk.
21233 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21236 ensure that the interfaces implemented by the ancestors are placed
21237 at the header of the generated list.
21238 (Expand_Interface_Conversion): Handle the case in which the displacement
21239 associated with the interface conversion is not statically known. In
21240 this case we generate a call to the new run-time subprogram Displace.

21242 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21243 Get_Tagged_Kind and Set_Tagged_Kind.
21244 (Tagged_Kind): New function that determines the tagged kind of a type
21245 with respect to limitedness and concurrency and returns a reference to
21247 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,

21251 secondary dispatch table respectively of a tagged type.
21253 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21254 (Expand_Interface_Conversion): New subprogram to indicate if the
21255 displacement of the type conversion is statically known.

21265 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21266 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21267 RE_TK_Tagged, RE_TK_Task.
21269 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21270 Init_Secondary_Tags_Internal to allow its use with interface types and
21271 also to generate the code for the new additional actual required
21272 by Set_Offset_To_Top.
21273 (Build_Init_Statements): In case of components associated with abstract
21274 interface types there is no need to generate a call to its IP.
21275 (Freeze_Record_Type): Generate Select Specific Data tables only for
21277 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21278 the bodies and specifications of the predefined primitive operations
21279 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21280 for concurrent types.

21284 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21285 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21286 properly protected objects and attach handler in the case of the
21287 restricted profile.
21288 Move embeded package Select_Expansion_Utilities into a separate external
21290 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
21291 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
21292 (Build_K, Build_S_Assignment): New subprograms, part of the select
21293 expansion utilities.

21300 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21301 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21302 about the use and expansion of SAVE_EXPRs in the various possible
21303 renaming handling cases.
21304 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21305 abusing DECL_FCONTEXT.

21405 covered by the tag of the source.
21407 2005-12-09 Robert Dewar <dewar@adacore.com>
21409 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

21424 component associated with the secondary table of an abstract interface
21425 type, return the entity associated with such abstract interface type.
21426 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21427 base type to create anonymous subtype, because entity may be a locally
21428 declared subtype or generic actual.
21429 (Find_Interface): New subprogram that given a tagged type and one of its
21430 component associated with the secondary table of an abstract interface
21431 type, return the entity associated with such abstract interface type.

21434 conversion cannot be handled at compile time. In this case we pass this
21435 information to the expander to generate the appropriate code.

21472 (Analyze_Component_Declaration): A limited component is
21473 legal within a protected type that implements an interface.
21474 (Collect_Interfaces): Do not add to the list the interfaces that
21475 are implemented by the ancestors.
21476 (Derived_Type_Declaration): If the parent of the full-view is an
21477 interface perform a transformation of the tree to ensure that it has
21478 the same parent than the partial-view. This simplifies the job of the
21479 expander in order to generate the correct object layout, and it is
21480 needed because the list of interfaces of the full-view can be given in
21482 (Process_Full_View): The parent of the full-view does not need to be
21483 a descendant of the parent of the partial view if both parents are
21485 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21486 "limited" the parent must be a limited type.

21500 (Process_Full_View): Improve the check for the "no hidden interface"
21501 rule as defined by AI-396.
21503 2005-12-09 Robert Dewar <dewar@adacore.com>
21505 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
21506 types, not on record subtypes.
21507 (Freeze_Entity): Code cleanup. Add barrier to the loop
21508 that generates the references for primitive operations. This allows to
21509 remove an unnecessary exception handler.

21560 available user-specified stream attributes on limited parameters to
21561 also test the type directly rather than only its underlying type (for
21562 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21563 attributes are visible at the point of the subprogram declaration.
21564 For Ada 2005, the error message is modified to indicate that the
21565 type's stream attributes must be visible (again, only for -gnat05).

21597 types use the corresponding record type. This was not needed before
21598 the implementation of Ada 2005 synchronized types because
21599 concurrent types were never tagged types in Ada 95.

21747 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
21748 a temporary if taking the address of something that is neither
21749 reference, declaration, or constant, since the gimplifier

21822 * gen-soccon.c: Complete value expansion should not be performed on
21823 TARGET, as it has the form of a math expression, and some components
21824 may be platform-defined macros.
21825 For VxWorks, generate the OK and ERROR values.
21826 New constants giving the sizes of the components of C struct timeval.

21838 deal with different cases of static and dynamic elaboration checks (all
21839 checks does not count in the first case, but does in the second).

21845 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21846 elementary types using the operator in standard. It is cleaner not to
21847 modify the programmers intent, especially in the case of floating-point.
21848 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21849 it did not matter because we always rewrote a/=b to not(a=b).
21850 (Expand_Allocator_Expression): For an allocator expression whose nominal
21851 subtype is an unconstrained packed type, convert the expression to its
21852 actual constrained subtype.
21853 Implement warning for <= or >= where < or > not possible
21854 Fix to Vax_Float tests (too early in many routines, causing premature
21855 Vax_Float expansions.
21857 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
21858 to be used with packages and generic packages as well as with

21861 of pragma Suppress (All_Checks)
21862 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
21863 a string literal for precise control over warnings.

21873 Allow optional = after -gnatm
21874 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21875 longer sets Elaboration_Checks.
21876 Code to set warning mode moved to Sem_Warn
21877 so that it can be shared by pragma processing.
21879 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
21882 * s-taprop-solaris.adb:
21883 Change some <= to =, to avoid new warning

21889 2005-11-14 Robert Dewar <dewar@adacore.com>
21891 * exp_vfpt.adb: Handle /= case
21892 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
21893 so that we do not get duplicate scaling for fixed point conversions.
21895 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
21897 2005-11-14 Matthew Gingell <gingell@adacore.com>
21899 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
21900 Increase default priority on Lynx from 15 to 17, and meet the Ada
21901 requirement that Default_Priority be ((Priority'First +
21902 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22004 we are not defining the type.
22005 <E_Record_Type>: Likewise.
22006 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22007 to get advantage of the new maybe_stabilize_reference interface, to
22008 ensure that what we reference is indeed stabilized instead of relying
22009 on assumptions on what the stabilizer does.
22010 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22011 type imported through a limited_with clause, use its non-limited view.
22012 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22014 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22015 of #if sections + explicit comparisons of convention identifiers.

22017 before early-returning for certain types when code generation is
22019 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22021 that we are not defining.
22022 (elaborate_expression_1): Do not create constants when creating
22023 variables needed by the debug info: the dwarf2 writer considers that
22024 CONST_DECLs is used only to represent enumeration constants, and emits
22026 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22027 object with an address clause into an indirect reference, drop the
22028 initializing expression.

22040 subtype to build an actual type with bounds template.
22041 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22042 is provided by the front-end, use that subtype to compute the size of
22043 the deallocated object.

22045 check for a potential violation of a No_Elaboration_Code restriction.
22046 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22047 with extra arguments to control whether to recurse through non-values

22050 maybe_stabilize, for common uses without restriction on lvalues and
22051 without need to check for the success indication.
22052 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22053 pass false instead of 0 as the FORCE argument which is a bool.
22054 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22055 attached to a renaming pointer has been properly stabilized, as no such
22056 object is attached otherwise.
22057 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22058 function uses the "target pointer" return mechanism.
22059 Reinstate conversion of the actual to the type of the formal
22060 parameter before any other specific treatment based on the passing
22061 mechanism. This turns out to be necessary in order for PLACEHOLDER
22062 substitution to work properly when the latter type is unconstrained.

22066 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22068 and to let the caller know if the stabilization has succeeded.
22070 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22071 static output of record constructor if all the components are constant.
22072 (gnat_build_constructor): For a record type, sort the list of field
22073 initializers in increasing bit position order.
22074 Factor common code to build a storage type for an unconstrained object
22075 from a fat or thin pointer type and a constrained object type.
22076 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22077 types variants, and process special cases of VIEW_CONVERT expressions
22078 as their NOP_EXPR counterpart to ensure we get to the
22079 CORRESPONDING_VARs associated with CONST_DECls.
22080 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22081 on the right-hand side.

22088 extracting the object if converting to a type variant.
22089 (create_var_decl): When a variable has an initializer requiring code
22090 generation and we are at the top level, check for a potential violation
22091 of a No_Elaboration_Code restriction.
22092 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22093 SIZE and SIZE_UNIT which we need for later back-annotations.

22096 is an unchecked union.
22097 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22098 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22099 main variant, just replace the VIEW_CONVERT_EXPR.

22235 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22236 for task component, in the case of a limited aggregate. The enclosed

22284 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22285 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22286 'Terminated for task interface class-wide objects. Generate a call to
22287 the predefined dispatching routine used to retrieve the _task_id from

22368 attribute of the N_Free_Statement.
22369 Generate itype for classwide designated object in both cases of

22632 declarations of the parent scope the parent is still private, use its
22633 full view to construct the full declaration of the derived type.
22634 (Build_Derived_Record_Type): Relax the condition that controls the
22635 execution of the check that verifies that the partial view and
22636 the full view agree in the set of implemented interfaces. In
22637 addition, this test now only takes into account the progenitors.
22638 (Derive_Interface_Subprograms): No need to derive subprograms
22639 of ancestors that are interfaces.
22640 (Derive_Subprograms): Remove formal No_Predefined_Prims and the
22642 Change name Is_Package to Is_Package_Or_Generic_Package
22643 (Complete_Subprograms_Derivation): Handle the case in which the full
22644 view is a transitive derivation of the ancestor of the partial view.
22645 (Process_Full_View): Rename local subprogram Find_Interface_In_
22646 Descendant to Find_Ancestor_Interface to leave the code more clear.
22647 Remove wrong code that avoids the generation of an error message
22648 when the immediate ancestor of the partial view is an interface.
22649 In addition some minor reorganization of the code has been done to
22650 leave it more clear.
22651 (Analyze_Type_Declaration): If type has previous incomplete tagged
22652 partial view, inherit properly its primitive operations.
22653 (Collect_Interfaces): Make public, for analysis of formal
22655 (Analyze_Interface_Declaration): New procedure for use for regular and
22656 formal interface declarations.
22657 (Build_Derived_Record_Type): Add support for private types to the code
22658 that checks if a tagged type implements abstract interfaces.
22659 (Check_Aliased_Component_Type): The test applies in the spec of an
22661 (Access_Type_Declaration): Clean up declaration of malformed type
22662 declared as an access to its own classwide type, to prevent cascaded
22664 (Collect_Interfaces): For private extensions and for derived task types
22665 and derived protected types, the parent may be an interface that must
22666 be included in the interface list.
22667 (Access_Definition): If the designated type is an interface that may
22668 contain tasks, create Master_Id for it before analyzing the expression
22669 of the declaration, which may be an allocator.
22670 (Record_Type_Declaration): Set properly the interface kind, for use
22671 in allocators, the creation of master id's for task interfaces, etc.

22680 subprogram declaration.
22681 Change name Is_Package to Is_Package_Or_Generic_Package
22682 (Process_Formals): A non null qualifier on a non null named access
22683 type is not an error, and is a warning only if Redundant_Constructs

22687 Ed Schonberg <schonberg@adacore.com>
22689 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure

22692 package instance of a generic child package.
22693 (Analyze_Package_Specification): When entering a private part of a
22694 package associated with a generic instance or formal package, the
22695 private declarations of the parent must be installed (by calling new
22696 procedure Install_Parent_Private_Declarations).
22697 Change name Is_Package to Is_Package_Or_Generic_Package
22698 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22699 record is absent in a generic context, which does not indicate a
22702 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22704 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22705 not try to rewrite a renamed stream attribute, because the operations
22706 on the type may not have been generated.
22707 Handle properly a renaming_as_body generated for a stream operation
22708 whose default is abstract because the object type itself is abstract.
22709 (Find_Type): If the type is incomplete and appears as the prefix of a
22710 'Class reference, it is tagged, and its list of primitive operations
22711 must be initialized properly.
22712 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22713 private declaration of a parent unit, prior to compiling the private
22714 part of a child unit, find on the scope stack the proper parent entity
22715 on which to link the use clause.
22716 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22718 (Analyze_Object_Renaming): An attribute reference is not a legal object
22719 if it is not a function call.

22735 * sem_res.adb (Resolve_Call): Provide a better error message whenever
22736 a procedure call is used as a select statement trigger and is not an
22737 entry renaming or a primitive of a limited interface.
22738 (Valid_Conversion): If the operand has a single interpretation do not
22739 remove address operations.
22740 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22741 statement to inhibit warning.
22742 (Resolve_Unary_Op): Do not produce a warning when
22743 processing an expression of the form -(A mod B)
22744 Use Universal_Real instead of Long_Long_Float when we need a high
22745 precision float type for the generated code (prevents gratuitous
22746 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22747 (Resolve_Concatenation_Arg): Improve error message when argument is an
22748 ambiguous call to a function that returns an array.
22749 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22750 there is an implicit operator in the given scope if we are within an
22751 instance: legality check has been performed on the generic.
22752 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
22753 after resolving operand, to avoid false warnings on overloaded calls.

22762 previously detected errors to ensure that its compilation
22763 with assertions enabled gives the same output that its
22764 compilation without assertions.

23733 (Check_Overriding_Inherited_Interfaces): Add suport to handle
23734 overloaded primitives.
23735 (Register_Interface_DT_Entry): Use the new name of the formal
23736 the the calls to Expand_Interface_Thunk
23738 * exp_dbug.ads: Augment comments on encoding of protected types to
23739 include the generation of dispatching subprograms when the type
23740 implements at least one interface.
23742 * lib.ads: Extend information in Load_Stack to include whether a given
23743 load comes from a Limited_With_Clause.
23745 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23746 whether a potential circularity is harmless, because it includes units
23747 loaded through a limited_with clause. Extends previous treatment which
23748 did not handle properly arbitrary combinations of limited and
23749 non-limited clauses.
23751 2005-09-01 Nicolas Setton <setton@adacore.com>
23753 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23754 to be encoded as typ___XBLU_lowerbound__upperbound instead of
23755 typ___XB_lowerbound__upperbound.
23757 2005-09-01 Thomas Quinot <quinot@adacore.com>
23759 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
23760 dummy access formal for RACW/RAS TypeCode TSS.
23761 (Build_TypeCode_Call): Do not generate dummy null access actual for
23762 calls to the TypeCode TSS.
23764 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23766 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23767 fully qualified name, to distinguish instances with the same local name.
23769 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
23772 2005-09-01 Robert Dewar <dewar@adacore.com>

23777 2005-09-01 Jerome Lambourg <lambourg@adacore.com>
23779 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
23780 (Free): New deallocation procedure for filter elements
23781 (Close): Deallocate any existing filter for the concerned connection
23783 2005-09-01 Laurent Pautet <pautet@adacore.com>
23785 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23786 position set is provided, we compute one in order to reduce the maximum
23787 length of the keys. This computation first selects a character
23788 position between 1 and the minimum length of the keys in order to
23789 avoid reducing one of the keys to an empty string.
23790 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23791 does not converge. The initialization procedure now comes with a
23792 maximum number of iterations such that when exceeded, an exception is
23793 raised in Compute. The user can initialize this ratio to another value
23795 Reformating and updated headers.
23797 2005-09-01 Javier Miranda <miranda@adacore.com>
23799 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23800 that given an entity T creates and returns an Itype that duplicates the
23801 contents of T. The returned Itype has the null-exclusion
23802 attribute set to True, and its Etype attribute references T
23803 to keep the association between the two entities.
23804 Update copyright notice
23806 * sem_aggr.adb (Check_Can_Never_Be_Null,
23807 Aggregate_Constraint_Checks, Resolve_Aggregate,
23808 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23810 * sem_ch5.adb (Analyze_Assignment): Code cleanup.
23812 2005-09-01 Gary Dismukes <dismukes@adacore.com>
23813 Robert Dewar <dewar@adacore.com>
23814 Hristian Kirtchev <kirtchev@adacore.com>
23816 * layout.adb (SO_Ref_From_Expr): Change Subtype_Mark to
23819 * par-ch6.adb (P_Subprogram): Handle parsing of Access_Definitions in
23821 Call Set_Result_Definition instead of Set_Subtype_Mark.
23822 (P_Subprogram_Specification): Add parsing of anonymous access result
23823 plus null exclusions. Call Set_Result_Definition instead of
23826 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23827 (P_Access_Type_Definition): Add parsing for an anonymous access result
23828 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23829 instead of Set_Subtype_Mark.
23831 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23832 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23833 (Result_Definition): New function for N_Function_Specifications.
23834 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23835 N_Function_Specification.
23836 (Set_Null_Exclusion_Present): Allow this flag for
23837 N_Function_Specification.
23838 (Set_Result_Definition): New procedure for N_Function_Specifications.
23839 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23840 and N_Function_Specification.
23842 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23843 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23844 Add support for LIMITED NEW for Ada 2005 AI-419
23845 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23846 syntax for anonymous access results.
23847 Replace Subtype_Mark field by Result_Definition in
23848 N_Function_Specification and N_Access_Definition specs.
23849 Add Null_Exclusion_Present to spec of N_Function_Specification.
23850 (Result_Definition): New function for N_Function_Specification and
23851 N_Access_Function_Definition.
23852 (Set_Result_Definition): New procedure for N_Function_Specification and
23853 N_Access_Function_Definition.
23855 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23856 Result_Definition for cases of N_Access_Function_Definition and
23857 N_Function_Specification.
23858 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23860 2005-09-01 Vincent Celier <celier@adacore.com>
23862 * lib-writ.adb: Update Copyright notice
23863 (Write_With_Lines): On platforms where file names are case-insensitive,
23864 record the file names in lower case.
23865 (Write_ALI): For D lines, on platforms where file names are
23866 case-insensitive, record the file names in lower case.
23868 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23869 Emmanuel Briot <briot@adacore.com>
23871 * lib-xref.adb (Output_Overridden_Op): Display information on
23872 overridden operation.
23874 * lib-xref.ads: Add documentation on overridden operations.
23876 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23879 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23880 overriding entity information.
23882 2005-09-01 Vincent Celier <celier@adacore.com>
23884 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23885 including those that are inherited.
23887 2005-09-01 Robert Dewar <dewar@adacore.com>
23889 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23891 * par-prag.adb: Implement new pragma Debug_Policy
23893 * sem_prag.adb Implement new pragma Debug_Policy
23894 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23895 Component_Size attribute specification. Give warning for ignored pragma
23898 * snames.h, snames.ads, snames.adb: Introduce entries in
23899 Preset_Names for Name_Disp_Asynchronous_Select,
23900 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23901 Name_Disp_Timed_Select.
23902 New pragma Debug_Policy
23904 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23906 Switch -gnata also sets Debug_Pragmas_Enabled
23908 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23909 handle an explicit -gnata when compiling predefined files.
23911 2005-09-01 Vincent Celier <celier@adacore.com>
23913 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23914 directories of projects that have no Ada sources.
23916 2005-09-01 Robert Dewar <dewar@adacore.com>
23918 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23919 (makes a difference for wide characters)
23921 * widechar.adb, widechar.ads:
23922 Add Wide_Char_Byte_Count feature to count chars vs bytes
23924 2005-09-01 Thomas Quinot <quinot@adacore.com>
23925 Ed Schonberg <schonberg@adacore.com>
23926 Robert Dewar <dewar@adacore.com>
23928 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23929 'Address attribute reference with an overloaded prefix, use the
23930 location of the prefix (not the location of the attribute reference) as
23931 the error location.
23932 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23933 a function renaming thereof, is a valid prefix for 'Size (where it is
23934 intepreted as a function call).
23935 (Statically_Denotes_Entity): New predicate to determine whether the
23936 prefix of an array attribute can be considered static.
23939 (Eval_Attr): Fix failure to evaluate Component_Size for
23940 unconstrained arrays (resulted in wrong value in packed case, since
23941 back end cannot handle this case)
23943 2005-09-01 Robert Dewar <dewar@adacore.com>
23945 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23946 error msgs for most common cases.
23947 Use new errout insertion char < (conditional warning)
23949 2005-09-01 Javier Miranda <miranda@adacore.com>
23950 Ed Schonberg <schonberg@adacore.com>
23952 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23953 become local to the whole package.
23954 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23955 the package was already analyzed the new algorithm "replaces" the
23956 real entities by the shadow ones. This is required to ensure that
23957 the order of these entities in the homonym chains does not change;
23958 otherwise we can have undefined references at linking time because
23959 in case of conflicts the external name of the entities will have
23960 a suffix that depends on the order of the entities in the chain.
23961 (Remove_Limited_With_Clause): Complementary code that completes the
23962 new algorithm and replaces the shadow entities by the real ones.
23963 (Install_Limited_Withed_Unit): When unchaining entities before the
23964 installation of the shadow entities, only regular entities of the
23965 public part must be taken into account. This is required to
23966 keep this routine in synch with the work done by Remove_Limited_
23968 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23969 even if unit is analyzed, because the analysis of the unit is
23970 idempotent in any case, and the limited view of the unit may have to
23971 be installed for proper visibility.
23972 (Expand_Limited_With_Clause): Even if the unit in the implicit
23973 with_clause has been analyzed already, a limited view of the package
23974 must be built for the current context, if it does not exist yet.
23976 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23977 Javier Miranda <miranda@adacore.com>
23978 Gary Dismukes <dismukes@adacore.com>
23980 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23981 defining entity for the instance body, make a new defining identifier
23982 rather than copying the entity of the spec, to prevent accidental
23983 sharing of the entity list.
23984 (Check_Private_View): When exchanging views of private types, build the
23985 list of exchanged views as a stack, to ensure that on exit the exchanges
23986 are undone in the proper order.
23987 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23988 Restore the compilation environment in case of instantiation_error.
23989 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23990 for an anonymous access result.
23991 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23992 (Formal_Entity): Handle properly the case of a formal package that
23993 denotes a generic package renaming.
23995 2005-09-01 Thomas Quinot <quinot@adacore.com>
23997 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23998 clause if the array aggregate is surrounded by parentheses.
24000 2005-09-01 Cyrille Comar <comar@adacore.com>
24001 Gary Dismukes <dismukes@adacore.com>
24002 Ed Schonberg <schonberg@adacore.com>
24003 Javier Miranda <miranda@adacore.com>
24005 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24007 to check if a type is Constrained in cases related to code generation
24008 (rather than semantic checking) since otherwise we do not generate
24009 similar code for mutable private types depending if their
24010 discriminants are visible or not.
24011 (Check_Abstract_Overriding): Do not complain about failure to override
24012 the primitive operations used in dispatching selects since they will
24013 always be overriden at the freeze point of the type.
24014 (Access_Definition): Separate out handling for resetting the scope
24015 of an anonymous access function result type. Retrieve the scope
24016 of the associated function rather than using Current_Scope, which
24017 does not have a consistent value (depends on whether we're in the
24018 middle of analyzing formal parameters). Add ??? comment about
24019 finding a cleaner way to handle the special cases of scope setting.
24020 (Process_Incomplete_Dependents): A protected operation is never a
24021 dispatching operation (only its wrapper may be).
24022 (Build_Derived_Record_Type): In case of tagged private types that
24023 implement interfaces add derivation of predefined primitive
24025 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24026 by two parameters that are used in case of derivation from abstract
24027 interface types: No_Predefined_Prims is used to avoid the derivation
24028 of predefined primitives from the interface, and Predefined
24029 Prims_Only is used to complete the derivation predefined primitives
24030 in case of private tagged types implementing interfaces.
24031 Fix typo in comments
24032 (Find_Interface_In_Descendant): Protect the frontend against
24033 wrong code with large circularity chains.
24034 (Is_Private_Overriding): Add support for entities overriding interface
24035 subprograms. The test failed because Entities associated with overriden
24036 interface subprograms are always marked as hidden (and used to build
24037 the secondary dispatch table); in this case the overriden entity is
24038 available through the field abstract_interface_alias (cf. override_
24039 dispatching_operation)
24040 (Access_Definition): Set the scope of the type to Current_Scope for the
24041 case of a function with an anonymous access result type.
24042 (Access_Subprogram_Declaration): Handle creation of the type entity for
24043 an access-to-function type with an anonymous access result.
24044 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24045 in handling for N_Access_Function_Definition.
24046 (Analyze_Subtype_Declaration): Modify the text of error message.
24047 (Derived_Type_Declaration): Modify the text of error message.
24048 (Process_Subtype): Modify the text of error message plus cleanup
24049 of one redundant error message.
24050 (Analyze_Component_Declaration): Code cleanup.
24051 (Analyze_Object_Declaration): Code cleanup.
24052 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24053 attribute in case of access types. Code cleanup.
24054 (Array_Type_Declaration): Code cleanup.
24055 (Process_Discriminants): Create the new null-excluding itype
24056 if required. Code cleanup.
24057 (Process_Subtype): Create the new null-excluding itype if
24058 required. Code cleanup.
24059 (Build_Derived_Record_Type): Code cleanup to avoid calling
24060 twice the subprogram derive_subprograms in case of private
24061 types that implement interfaces. In this particular case the
24062 subprogram Complete_Subprograms_Derivation already does the
24063 job associated with the second call.
24065 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24066 conversion to the full view when generating an operation for a
24067 discriminant whose type may currently be private.
24069 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24070 Javier Miranda <miranda@adacore.com>
24072 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24073 V (Obj.F), the rewriting does not involve the indexed component, but
24074 only the selected component itself.
24075 Do not apply the transformation if the analyzed node is an actual of a
24076 call to another subprogram.
24077 (Complete_Object_Operation): Retain the entity of the
24078 dispatching operation in the selector of the rewritten node. The
24079 entity will be used in the expansion of dispatching selects.
24080 (Analyze_One_Call): Improve location of the error message associated
24082 (Analyze_Selected_Component): No need to resolve prefix when it is a
24083 function call, resolution is done when parent node is resolved, as
24085 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24086 when attempting to resolve a call transformed from its object notation.
24087 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24088 of the argument list for each interpretation of the operation.
24089 (Try_Object_Operation): The designated type of an access parameter may
24090 be an incomplete type obtained through a limited_with clause, in which
24091 case the primitive operations of the type are retrieved from its full
24093 (Analyze_Call): If this is an indirect call, and the return type of the
24094 access_to_subprogram is incomplete, use its full view if available.
24096 2005-09-01 Javier Miranda <miranda@adacore.com>
24097 Gary Dismukes <dismukes@adacore.com>
24099 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24100 access types the null-exclusion and access-to-constant attributes must
24102 (Analyze_Return_Statement): When the result type is an anonymous access
24103 type, apply a conversion of the return expression to the access type
24104 to ensure that appropriate accessibility checks are performed.
24105 (Analyze_Return_Type): For the case of an anonymous access result type,
24106 generate the Itype and set Is_Local_Anonymous_Access on the type.
24107 Add ??? placeholder for check to disallow returning a limited object
24108 in Ada 2005 unless it's an aggregate or a result of a function call.
24109 Change calls from Subtype_Mark to Result_Definition.
24110 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24111 Result_Definition in call to Make_Function_Specification.
24112 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24113 Set_Result_Definition.
24114 (Make_Inequality_Operator): Change formal Subtype_Mark to
24115 Result_Definition in call to Make_Function_Specification.
24116 (Process_Formals): Create the new null-excluding itype if required.
24117 (New_Overloaded_Entity): For an entity overriding an interface primitive
24118 check if the entity also covers other abstract subprograms in the same
24119 scope. This is required to handle the general case, that is, overriding
24120 other interface primitives and overriding abstract subprograms inherited
24121 from some abstract ancestor type.
24122 (New_Overloaded_Entity): For an overriding entity that comes from
24123 source, note the operation that it overrides.
24124 (Check_Conformance, Type_Conformant): Addition of one new formal
24125 to skip controlling formals in the analysis. This is used to
24126 handle overloading of abstract interfaces.
24127 (Base_Types_Match): Add missing case for types imported from
24128 limited-with clauses
24129 (New_Overloaded_Entity): Add barrier to protect the use of
24130 the "alias" attribute.
24132 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24134 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24135 verify that the procedure and the entry are mode conformant.
24136 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24137 as a different operator, which is often a cut-and-paste error.
24139 2005-09-01 Javier Miranda <miranda@adacore.com>
24140 Ed Schonberg <schonberg@adacore.com>
24142 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24143 used in controlling parameters exclude null because it is necessary to
24144 read the tag to dispatch, and null has no tag.
24145 (Override_Dispatching_Operation): If the previous operation is inherited
24146 from an interface, it becomes hidden and does not participate in later
24149 2005-09-01 Javier Miranda <miranda@adacore.com>
24150 Ed Schonberg <schonberg@adacore.com>
24151 Gary Dismukes <dismukes@adacore.com>
24153 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24154 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24155 the expander will generate the corresponding run-time check to evaluate
24157 (Resolve_Call): Check for legal type of procedure name or prefix that
24158 appears as a trigger in a triggering alternative.
24159 (Valid_Conversion): If expression is ambiguous and the context involves
24160 an extension of System, remove System.Address interpretations.
24161 (Resolve_Qualified_Expression): Reject the case of a specific-type
24162 qualification applied to a class-wide argument. Enhance comment
24163 to explain checking of Original_Node.
24164 (Resolve_Type_Conversion): The location of the error message was not
24165 general enough to handle the general case and hence it has been removed.
24166 In addition, this patch improves the text of the message.
24167 (Resolve_Type_Conversion): Add missing support for access to interface
24169 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24170 do not expand if the expression is the actual in a call, because proper
24171 expansion will take place when the call itself is expanded.
24172 (Resolve_Allocator): If the context is an unchecked conversion, the
24173 allocator inherits its storage pool, if any, from the target type of
24176 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24177 Javier Miranda <miranda@adacore.com>
24179 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24180 inherited interface operation that has an implementation, use the
24181 implementation to avoid spurious ambiguities.
24182 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24183 use the Corresponding_Record_Typ attribute to look for the interface
24184 because it is set by the expander (and hence it is not always
24185 available). For this reason we traverse the list of interfaces
24186 (available in the parent of the concurrent type).
24187 (Interface_Present_In_Ancestor): Handle entities from the limited view
24189 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24191 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24192 from the list of required components.
24193 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24194 primitive procedure of a limited interface with a controlling first
24196 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24198 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24199 capture if it is generated in the second operand of a short-circuit
24201 Do not capture values for variables with address clauses.

24990 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24991 longer protected objects. They have been replaced by lower-level
24992 suspension objects made up by a mutex and a condition variable (or
24993 their equivalent given a particular OS) plus some internal data to
24994 reflect the state of the suspension object.
24995 (Initialize, Finalize): Add this initialization procedure for
24996 Suspension_Object, which is a controlled type.

25457 (Is_Unchecked_Conversion): Improve the test that recognizes
25458 instantiations of Unchecked_Conversion, and allows them in bodies that
25459 are to be inlined by the front-end. When the body comes from an

25482 object or component (that is, when Is_Local_Anonymous_Access is true).
25483 Prevent the special checks for conversions of access discriminants in
25484 the case where the discriminant belongs to a nonlimited type, since

25486 way as a normal component of an anonymous access type.
25487 (Resolve_Allocator): When an allocator's designated type is a class-wide
25488 type, check that the accessibility level of type given in the
25489 allocator's expression or subtype indication is not statically deeper
25490 than the level of the allocator's access type.

25506 pragma Restrictions (No_Obsolescent_Features).
25507 (Check_Direct_Boolean_Operator): If the boolean operation has been
25508 constant-folded, there is nothing to check.
25509 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25510 check on possible violation of restriction No_Direct_Boolean_Operators
25511 until after expansion of operands, to prevent spurious errors when

25547 both bound checks, rather than a conjunction.
25548 (Insert_Valid_Check): If the expression is an actual that is an indexed
25549 component of a bit-packed array, force expansion of the packed element
25550 reference, because it is specifically inhibited elsewhere.

26516 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26517 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26518 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26519 analyzed if expansion is disabled (which could otherwise cause spurious
26520 error messages if expansion has been disabled due to previous
26521 (unrelated) errors).
26523 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26524 is disabled, the entity denoted by the argument is the access type
26525 itself, not an underlying record type, so there is no need to go back
26526 to the Corresponding_Remote_Type.
26528 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26529 Robert Dewar <dewar@adacore.com>
26531 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26532 expand a call to an instance of
26533 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

26535 check is also generated, to ensure that the tag passed to the instance
26536 denotes a type in the class.
26537 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26538 of Name_Generic_Dispatching_Constructor.
26540 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26541 05 unit for AI-260-02).

26555 the case of renaming of stream attributes when the renaming denotes a
26556 generic formal subprogram association for an abstract formal subprogram.
26557 Check that the attribute is a primitive stream attribute (and not
26558 a class-wide stream attribute) and then rewrite the attribute name
26559 as the name of the appropriate compiler-generated stream primitive.
26561 2005-03-29 Robert Dewar <dewar@adacore.com>
26563 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26571 itype whose parent is controlled and not yet frozen, do not create a
26572 freeze node for the itype if expansion is disabled.
26574 2005-03-29 Vincent Celier <celier@adacore.com>
26576 * make.adb (Gnatmake): Don't fail if the main project file is declared
26577 as having no Ada sources. Do not display message "no sources to
26578 compile" in quiet output.
26580 2005-03-29 Doug Rupp <rupp@adacore.com>
26582 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26593 missing TYPE Improve the error message generated when compiling a
26594 limited interface in Ada83 or Ada95 mode.
26596 2005-03-29 Robert Dewar <dewar@adacore.com>
26598 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26599 rather than proceed ahead using a junk attribute name.
26601 2005-03-29 Vincent Celier <celier@adacore.com>
26603 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26605 * prj-part.adb (Parse_Single_Project): Set the location of a project
26606 on its defining identifier, rather than on the reserved word "project".
26608 * prj-proc.adb (Expression): Adapt to the fact that default of external
26609 references may be string expressions, not always literal strings.
26610 (Recursive_Process): Set Display_Name equal to Name
26611 when Location is No_Location, that is when there is no actual file.
26612 Get the Display_Name of the project from the source, when it is not a
26614 (Process): Use the Display_Name in error messages
26616 * prj-strt.adb (External_Reference): Allow default to be string
26617 expressions, not only literal strings.
26619 2005-03-29 Vincent Celier <celier@adacore.com>

26627 forbid conversion of a local access-to-subprogram type to a remote one.
26629 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26630 equivalent type for a remote access-to-subprogram type, go back to the
26631 original RAS entity when displaying an error message, so the casing is
26632 the original source casing.

26636 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26639 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26641 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26642 subtype if code is being pre-analyzed, to prevent un-expanded
26643 references to protected formals, among others.
26644 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26645 interpretation that can be a call, include the result of the call as a
26646 possible interpretation of the dereference.
26648 * sem_ch5.adb (Process_Bounds): Determine type of range by
26649 pre-analyzing a copy of the original range, and then analyze the range
26650 with the expected type.
26652 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26653 with an overloaded prefix where not all interpretations yield an
26654 access to subprogram, do not rewrite node as a call.
26655 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26656 the node as a call once the context identifies the interpretation of
26657 the prefix whose call yields the context type.
26658 (Valid_Conversion): For the case of a conversion between
26659 local access-to-subprogram types, check subtype conformance using
26660 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26661 detailed error message.
26663 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26665 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26666 indicator, indicate that the formal can never be null.
26667 (Process_Formals): If a formal has a non_null indicator, insert the
26668 resulting subtype immediately before the enclosing subprogram decl,
26669 and not at the beginning of the corresponding declarative part, to
26670 prevent access before elaboration (Ada2005).

26779 to install the visible declarations of the enclosing scope of a
26780 record_type_with_private to establish the proper visibility before
26781 freezing the entity and related subprograms.

26791 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
26792 into a new Check_Attr subprogram, in order to provide a more
26793 explanatory error message (including the name of the missing attribute).
26794 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26795 subprogram determines whether a default implementation exists for a
26796 given stream attribute.
26797 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
26798 Determine whether to generate a default implementation for each stream
26799 attribute separately, as this depends on the specific attribute.
26801 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
26802 limited extension where a stream attribute is missing for a limited
26803 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27318 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
27319 messages by the correct RENAMES (quotes removed).
27321 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
27322 attribute First_Tag_Component.

27334 (Task_Body_Procedure): Removed.
27335 (Set_Task_Body_Procedure): Removed.
27336 These subprogram have been removed because the attribute
27337 Task_Body_Procedure has been moved to the corresponding task type
27338 or task subtype entity to leave a field free to store the list
27339 of interfaces implemented by a task (for AI-345)
27340 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27341 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27342 expression flag Do_Range_Check
27343 (Exception_Junk): Change to Flag7 to accomodate above change
27344 (Box_Present, Default_Name, Specification, Set_Box_Present,
27345 Set_Default_Name, Set_Specification): Expand the expression
27346 "X in N_Formal_Subprogram_Declaration" into the corresponding
27347 two comparisons. Required to use the csinfo tool.

27350 "with string" given.
27352 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27355 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27358 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27359 attribute Task_Body_Procedure rather than the old semantic field that
27360 was available in the task_type_declaration node.
27362 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27363 interface type definitions.
27364 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27367 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27368 task type declaration.

27370 protected type declaration.
27372 2005-03-15 Doug Rupp <rupp@adacore.com>
27373 Vincent Celier <celier@adacore.com>
27375 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27376 (Gen_Output_File_C): Likewise.
27377 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27379 2005-03-15 Thomas Quinot <quinot@adacore.com>
27381 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27382 is an N_Raise_Constraint_Error node, create a new copy of it without
27383 going through a call to Duplicate_Subexpr.
27385 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27386 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

27388 Ed Schonberg <schonberg@adacore.com>
27394 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27395 representation clause that prescribes a size not equal to the rounded
27396 size of their types.
27397 (gnat_to_gnu_entity, case E_Component): Always look at
27398 Original_Record_Component if Present and not the entity.

27400 of tagged extension types by not making field for components that are
27402 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27403 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27404 expression to the type of the object when the object is constant.
27405 Reverse defer_debug_incomplete_list before traversing it, so that trees
27406 are processed in the order at which they were added to the list. This
27407 order is important when using the stabs debug format.
27408 If we are deferring the output of debug information, also defer this
27409 output for a function return type.
27410 When adding fields to a record, prevent emitting debug information
27411 for incomplete records, emit the information only when the record is
27413 (components_to_record): New parameter defer_debug.
27414 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27415 (gnat_to_gnu_field_decl): New function.

27417 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27418 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27419 No longer update discriminants to not be a COMPONENT_REF.
27420 (copy_alias_set): Strip padding from input type; also handle
27421 unconstrained arrays properly.
27423 * gigi.h (write_record_type_debug_info): New function.
27424 Convert to use ANSI-style prototypes. Remove unused
27425 declarations for emit_stack_check, elab_all_gnat and
27426 set_second_error_entity.
27427 (gnat_to_gnu_field_decl): New decl.
27429 * utils.c (write_record_type_debug_info): New function.

27432 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27433 (update_pointer_to): Fix pasto.
27434 (convert) <UNION_TYPE>: Accept slight type variations when
27435 converting to an unchecked union type.
27437 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27438 replace the N_Freeze_Entity with a null statement.
27440 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27441 within a constrained subcomponent of an enclosing record, place the
27442 freeze nodes in the scope stack entry for the enclosing record.
27443 (Undelay_Type): New Subprogram.
27444 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27445 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27446 within records; allow them to have freeze nodes if their base types
27449 * exp_util.adb (Remove_Side_Effects): Properly test for
27450 Expansion_Delayed and handle case when it's inside an
27451 N_Qualified_Expression.
27453 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27454 Comes_From_Generic, to recognize accurately that the parent type in a
27455 derived type declaration can be traced back to a formal type, because
27456 it is one or is derived from one, or because its completion is derived
27458 (Constrain_Component_Type): If component comes from source and has no
27459 explicit constraint, no need to constrain in in a subtype of the
27461 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27462 Minor change to propagate Is_Ada_2005 flag
27464 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27465 Expansion_Delayed is False.
27466 (assoc_to_constructor): Ignore fields that have a
27467 Corresponding_Discriminant.
27468 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27469 function returns "by target", dereference the target pointer using the
27470 type of the actual return value.
27471 <all>: Be prepared for a null gnu_result.
27472 (processed_inline_subprograms): Check flag_really_no_inline
27473 instead of flag_no_inline.

27479 2005-03-15 Robert Dewar <dewar@adacore.com>
27480 Ed Schonberg <schonberg@adacore.com>
27481 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27483 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27484 Must_Be_Byte_Aligned for cases where we do not need to use a
27485 System.Pack_nn unit.
27487 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27489 Needed now that we do some processing for IN parameters as well. This
27490 may well fix some unrelated errors.
27491 (Expand_Call): Handle case of unaligned objects (in particular those
27492 that come from packed arrays).
27493 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27494 renamed entity is an inherited operation, re-expand the call using the
27495 original operation, which is the one to call.
27496 Detect attempt to inline parameterless recursive subprogram.
27497 (Represented_As_Scalar): Fix to work properly with private types
27498 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27499 accurate estimate. Yields True in far fewer cases than before,
27500 improving the quality of code that depends on this test.
27502 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27503 over both visible and private declarations to remove them from tree,
27504 and mark subprograms declared in package as eliminated, to prevent
27505 spurious use in subsequent compilation of generic units in the context.
27507 * exp_util.ads: Minor cleanup in variable names
27509 * sem_eval.ads, sem_eval.adb: Minor reformatting
27510 (Compile_Time_Known_Bounds): New function
27512 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27514 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27515 determining whether an unchecked conversion is needed for the argument
27516 of an initialization call.
27518 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27520 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27521 that appears in the instantiation rather than the internal subtype
27522 generated in the wrapper package, to avoid anomalies in gigi when the
27523 target is derived from a private type whose full view is an access type.
27525 2005-03-15 Robert Dewar <dewar@adacore.com>
27527 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27529 Add documentation to replace the use of this flag
27530 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27533 2005-03-15 Thomas Quinot <quinot@adacore.com>
27535 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27536 here from exp_attr so it can be shared between exp_attr and exp_dist.
27537 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27538 all TSS names, not a subset thereof, and the previous name introduced
27539 an unnecessarily confusion that a distinction might exist between
27540 "OK" TSS names and some "not OK" TSS names.
27542 2005-03-15 Doug Rupp <rupp@adacore.com>
27544 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27547 2005-03-15 Pascal Obry <obry@adacore.com>
27548 Eric Botcazou <ebotcazou@adacore.com>
27552 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27553 when IN_RTS. This is to work around a bootstrap path problem.
27555 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27556 table and pass it to __gnat_install_SEH_handler().
27557 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27559 * lang.opt: Fix specification of -fRTS=.
27561 2005-03-15 Doug Rupp <rupp@adacore.com>
27562 Bernard Banner <banner@adacore.com>
27563 Vincent Celier <celier@adacore.com>
27564 Arnaud Charlet <charlet@adacore.com>
27567 This change works fine when gnatlib is built from the gcc directory,
27568 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27569 is not passed to ada/Makefile.in, so more work is needed by a
27570 Makefile/configure expert.
27572 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27573 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27574 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27576 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27577 Run ranlib on libgccprefix.a
27578 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27579 (ADA_INCLUDE_SRCS): Split Ada packages.
27581 2005-03-15 Robert Dewar <dewar@adacore.com>
27583 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27585 * impunit.adb: Add GNAT.UTF_32
27587 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27589 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27590 now uses GNAT.UTF_32).
27592 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27593 capabilities for categorizing characters using Unicode categories
27595 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27597 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27598 instantiation that has been rewritten as a package body, retrieve spec
27599 to generate proper name for implicit_with_clause.
27600 (Install_Parents): Recognize a parent that is an instantiation but has
27601 been rewritten as a package declaration during analysis.
27603 2005-03-15 Javier Miranda <miranda@adacore.com>
27604 Ed Schonberg <schonberg@adacore.com>
27606 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27607 parameter reported some error we immediately return. This improves the
27608 behaviour of the frontend in case of errors.
27609 (Install_Parent, Remove_Parent): Introduce new flag
27610 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27611 ancestor of a generic child unit, when the child is being instantiated.
27612 (Inline_Instance_Body): If we are compiling the private
27613 part or the body of a child unit, restore the proper visibility of the
27614 parents after compiling the instance body.
27616 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27617 Javier Miranda <miranda@adacore.com>
27620 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27621 of a private type, in which case it is underlying_type that denotes
27622 the proper task. Also modified to use the new entity attribute
27623 that is directly available in the task type and task subtype entities
27624 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27625 arrays when other dimensions than the first are constrained by
27626 discriminants of an enclosing record.
27627 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27628 a combination of indexed and selected components, find ultimate entity
27629 and generate the appropriate reference for it, to suppress spurious
27631 (Note_Possible_Modification): If an entity name has no entity, return.
27632 (Is_Variable): A function call never denotes a variable.
27633 (Requires_Transient_Scope): For record types, recurse only on
27634 components, not on internal subtypes that may have been generated for
27635 constrained components.
27637 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27639 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27640 Eliminated as candidates for resolution. Both efficient, and avoids
27641 anomalies with operators declared in deleted code.
27642 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27643 expansion is disabled (as when compiling a generic) to prevent spurious
27644 warnings on prefixes of selected components.
27646 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27648 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27649 attached to a list before checking whether it appears in the private
27650 declarations of the current package.
27651 (Make_Inequality_Operator): Insert declaration in proper declarative
27652 list rather than just setting the Parent field, so that
27653 Is_Private_Declaration can handle it properly.
27655 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27657 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27658 a renaming a body, check that the renamed subprogram in not intrinsic.
27659 (Find_Direct_Name): If several use_visible entities hide
27660 each other, and the context is a predefined file compiled through
27661 rtsfind, keep only the entity that comes from a predefined file.
27663 2005-03-15 Geert Bosch <bosch@adacore.com>
27665 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27666 long float padding to also cover AMD64 and IA64.
27668 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27670 * s-imgwch.adb: Add with and use of Interfaces.
27671 (Img_Wide_Character): Change type of Val to Unsigned_16.
27672 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27674 2005-03-15 Matthew Gingell <gingell@adacore.com>

27719 Cyrille Comar <comar@adacore.com>
27720 Sergey Rybin <rybin@adacore.com>
27722 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27723 too specific and long-winded to be appropriate for the GNAT User's
27725 Warn about use of GCC switches not documented in the GNAT User's Guide,
27726 as these may cause generated code to not conform to Ada semantics.
27727 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27728 Add documentation for -gnat95 and -gnat05 switches
27729 Remove paragraph documenting obsolete way to refer to third party
27731 Add a few references to Ada_05 that were missing.
27732 Update documentation on -gnatZ/-gnatL.

27779 2005-02-12 Richard Henderson <rth@redhat.com>
27781 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

28177 procedure", covering the case of a call to a formal abstract procedure
28178 that has statically tagged operands.

28180 a tag-indeterminate function call whose type is an ancestor of the

28269 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28271 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28272 (components_to_record): Test it.

28281 handle other cases like RECORD_TYPE.
28283 * utils.c (gnat_pushdecl): Set TREE_NO_WARNING.
28285 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28287 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28288 component of an array of arrays in an assignment context, and the
28289 aggregate has component associations that require sliding on
28290 assignment, force reanalysis of the aggregate to generate a temporary
28291 before the assignment.
28292 (Must_Slide): Make global to the package, for use in Gen_Assign.
28294 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28296 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28297 unchecked union with no inferable discriminants, return a
28298 Raise_Program_Error node, rather than inserting it at the point the
28300 (Expand_Record_Equality, Component_Equality): Handle properly the case
28301 where some subcomponent is an unchecked union whose generated equality
28302 code raises program error.
28304 2005-02-09 Doug Rupp <rupp@adacore.com>

28310 Arnaud Charlet <charlet@adacore.com>
28312 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28313 address of the exception registration. The Win32 version of this
28314 routine calls __gnat_install_SEH_handler() to initialize the SEH
28315 (Structured Exception Handling) handler.
28316 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28317 SEH (Structured Exception Handling) now.
28318 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28319 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28320 preprocessor condition protecting the call to the extra eh setup
28321 subprogram, which is only available for the ppc target.
28322 (__gnat_clear_exception_count): replaced reference to
28323 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28325 * seh_init.c: New file.
28327 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28328 (GNATBIND_OBJS): Idem.
28330 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28331 routine takes a new parameter (a pointer to the exception registration
28332 for the SEH (Structured Exception Handling) support.
28334 * raise.h: (__gnat_install_SEH_handler): New prototype.
28335 Update copyright notice.
28337 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28338 record and initialize it by calling __gnat_install_SEH_handler.
28340 2005-02-09 Vincent Celier <celier@adacore.com>
28342 * make.adb (Gnatmake): Do not fail when the main project has no object

28348 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28349 [VMS]: Add translations for g-enblsp.adb.
28351 * s-asthan-vms.adb: Removed.
28352 * s-asthan-vms-alpha.adb: Added.

28363 -shared-libgcc is now used by default on some systems (e.g. linux with
28365 Remove references to Makefile.prolog/generic, no longer used.
28367 2005-02-09 Vincent Celier <celier@adacore.com>
28369 * prj-makr.adb (Process_Directory): Put file name in canonical case
28370 before matching against the patterns.
28371 If gnatname has been invoked as <prefix>-gnatname
28372 then invoke the compiler as <prefix>-gcc, not just "gcc".
28374 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28376 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28377 with expansion disabled. The actual subtype is needed among other
28378 places when the selected component appears in the context of a loop
28379 bound, and denotes a packed array.
28380 (Operator_Check): Always use the first subtype in the
28381 error message, to avoid the appearance of internal base types.
28382 (Transform_Object_Operation): Copy each actual in full
28383 to the parameter associations of the constructed call, rather than
28384 using the shallow copy mechanism of New_Copy_List. This ensures that
28385 the chaining of named associations is done properly.
28386 (Complete_Object_Operation): Rewrite node, rather than
28387 replacing it, so that we can trace back to the original selected
28390 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28391 and calls that use object notation, if the called function is not
28392 declared in a withed unit, place the elaboration constraint on the
28393 unit in the context that makes the function accessible.
28394 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28395 imposes an elaboration constraint between two packages.
28397 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28399 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28400 views of a private type after handling its private dependents, to
28401 maintain proper stack discipline between entry and exit from the
28404 2005-02-09 Cyrille Comar <comar@adacore.com>
28406 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

28411 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
28412 fields for foreign threads.

28417 recursion warnings when compiled with -gnatdm.
28419 2005-02-09 Robert Dewar <dewar@adacore.com>
28421 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28422 Slight fix to documentation of -gnaty with no parameters
28424 * xr_tabls.ads: Add ??? comment for missing overall comment
28426 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28427 we now use by default.
28429 * xsnames.adb: Adjust end of file test to look for five space followed
28430 by '#' instead of six spaces. The format of xsnames.adb was modified
28431 in the last update.
28433 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28436 * clean.adb: Minor reformatting.
28438 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28439 gnatname.adb: Minor reformatting
28440 Add 2005 to copyright output when utility is run
28442 * csets.adb: Eliminate obsolete comment
28444 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28447 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28449 2005-02-09 Sergey Rybin <rybin@adacore.com>
28451 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28452 the difference between compact and incompact layout and add the record
28453 representation clause to the example illustrating different layouts.
28454 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28455 component clauses").
28457 2005-02-09 Florian Villoing <villoing@adacore.com>
28459 * gnat_ugn.texi: Fix typos.
28460 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28462 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28463 in the generated documentation.
28465 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28467 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

28507 * exp_util.ads: Minor correction in comment.
28509 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28511 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28512 since this procedure is now too complex to be worth inlining.

28762 is to check if two function signatures for a call-site and a callee are
28763 compatible enough for the call to be valid. The underlying purpose is
28764 to check if a call to a mapped builtin is using the right interface.
28765 The current code actually does not check antyhing - this a placeholder
28766 for future refinements.
28767 (gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle
28768 builtin calls for convention Intrinsic.

28811 variable Dynamic_Async.
28812 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

28817 structure of GARLIC and PolyORB RPC receivers.
28818 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
28820 Simplify elaboration code for RCI packages.
28822 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

29186 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29187 dereference is rewritten to an explicit one, generate a reference to
29188 the entity denoted by its prefix using the original prefix node, so

29190 access value, if appropriate.
29192 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29193 emitting 'assigned but never read' warning on a variable on the basis

29209 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29210 subprogram which is Imported with convention Intrinsic if an
29211 External_Name argument is specified.

29263 2004-12-07 Ed Schonberg <schonberg@adacore.com>
29266 (Generate_Reference): Handle properly a reference to an entry formal,
29267 when an accept statement has a pragma Unreferenced for it.
29269 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29270 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29271 the body, to ensure that warnings are properly emitted for each accept
29272 statement of a given task entry.
29274 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
29276 * Makefile.in: Add support for foreign threads on VMS.

29294 (Remove_Next_Debug): Same fix
29296 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29297 maintain back pointers now, though we did not used to, and comments
29299 (Prepend): Remove pragma Inline.
29300 (Remove_Next): Same cleanup
29302 2004-12-07 Thomas Quinot <quinot@adacore.com>
29304 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29305 used to record an implicit dereference as a read operation on its
29306 prefix when operating under -gnatc. Necessary to avoid spurious
29307 'variable assigned but never read' warnings in that mode.
29308 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29309 is a non-overloaded implicit dereference, call the above subprogram to
29310 ensure proper recording of references.
29312 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29314 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29315 to be resolved later as part of Analyze_Iteration_Scheme's call to
29318 2004-12-07 Ed Schonberg <schonberg@adacore.com>

29356 Files" with the new tool and package names.
29357 Reformatting to suppress most of the warnings for line too long
29358 Document the new section "Project Search Path:" in the output of
29360 Add gnatmetric section
29362 2004-12-07 Vincent Celier <celier@adacore.com>
29364 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29365 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29366 and -eit to -ept. Added qualifier
29367 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29369 2004-11-27 Andreas Schwab <schwab@suse.de>
29371 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29373 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29375 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29376 internal implementation unit GNAT.Sockets.Thin,
29377 as their usage for sockets is non-portable (using the read and write
29378 functions from the system runtime library is fine on UNIX but won't
29379 work under Windows).
29381 * mingw32.h: Update copyright notice.
29383 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29385 * ada-tree.h: Minor reformatting of previous change to avoid lines
29386 longer than 79 characters.

29409 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29411 * adaint.h, adaint.c
29412 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29414 Add also a cast to kill another warning.
29415 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29416 parameter with the priority class of the parent process instead of
29417 always using the NORMAL_PRIORITY_CLASS.
29418 (__gnat_dup): New function.
29419 (__gnat_dup2): New function.
29420 (__gnat_is_symbolic_link): Enable the effective body of this
29421 function when __APPLE__ is defined.
29423 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29426 2004-11-18 Olivier Hainque <hainque@adacore.com>
29428 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29429 address of which may be used to represent "others" and "all others"
29430 choices in exception tables, instead of the current harcoded
29431 (void *)0 and (void *)1.
29432 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29434 * gigi.h (others_decl, all_others_decl): New decls representing the
29435 new Others_Value and All_Others_Value objects.
29436 (struct attrib): Rename "arg" component as "args", since GCC expects a
29437 list of arguments in there.
29439 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29440 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29443 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29444 others_decl and all_others_decl instead of hardcoded dummy addresses
29445 to represent "others" and "all others" choices, which is cleaner and
29446 more flexible with respect to the possible eh pointer encoding policies.
29448 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29449 (process_attributes): Account for the naming change of the "args"
29450 attribute list entry component.
29452 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29453 cumulating attributes for different entities into a single list.
29454 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29455 attributes for the current entity and propagate first subtype
29456 attributes to other subtypes.
29457 <E_Procedure>: Attribute arguments are attr->args and not
29458 attr->arg any more.
29459 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29460 argument provided, as this is what GCC expects. Use NULL_TREE instead
29463 2004-11-18 Robert Dewar <dewar@adacore.com>
29465 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29466 Minor reformatting througout (including new function specs)
29467 Add ??? comments asking for clarification.
29469 2004-11-18 Thomas Quinot <quinot@adacore.com>
29471 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29472 incomplete duplicate implementation of this subprogram from butil.
29474 2004-11-18 Thomas Quinot <quinot@adacore.com>

29477 procedures factors the common processing for building an RPC receiver
29478 for an RCI package or an RACW type.
29479 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29480 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29481 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29483 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29485 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29487 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29488 distribution subprogram identifiers that are either subprogram numbers

29491 string distribution identifiers assigned to a given subprogram.
29492 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29493 (Add_RAS_Dereference_TSS): Add comments.
29494 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29495 is not referenced yet because it will be used by the PolyORB DSA
29497 (Insert_Partition_Check): Remove fossile code.
29498 (First_RCI_Subprogram_Id): Document this constant.
29499 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29501 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29502 replaced with calls to Get_Library_Unit_Name_String. Previously there
29503 were several instances of the same code in different locations in the
29504 compiler; this checkin completes the replacement of all of these
29505 instances with calls to a common subprogram.
29506 Minor reformatting.
29508 * sem_dist.adb: Remove comment noting that RPC receiver generation
29509 should be disabled for RACWs that implement RASs.
29510 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29512 * sem_util.ads, sem_util.adb (Has_Stream): New function
29513 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29514 qualified name of a library unit into the name buffer.
29515 (Note_Possible_Modification): Generate a reference only
29516 if the context comes from source.
29518 * snames.ads (PCS_Names): New subtype corresponding to names of
29519 supported implementations of the Partition Communication Subsystem
29520 (PCS) (i.e. the runtime library support modules for the distributed

29534 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29535 (Expand_Pragma_Psect_Object): New procedure
29536 These procedures contain the revised and cleaned up processing for
29537 these two pragmas. This processing was formerly in Sem_Prag, but
29538 is more appropriately moved here. The cleanup involves making sure
29539 that the pragmas are properly attached to the tree, and that no
29540 nodes are improperly shared.
29542 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29543 pragmas to Exp_Prag, which is more appropriate.
29544 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29545 check for duplicates Remove use of Is_Psected flag, no longer needed.
29546 Use new Make_String_Literal function with string.
29548 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29549 that are functions return universal values, that have to be converted
29550 to the context type.
29551 Use new Make_String_Literal function with string.
29552 (Get_Stream_Convert_Pragma): New function, replaces the use of
29553 Get_Rep_Pragma, which had to be kludged to work in this case.
29555 * freeze.adb: Use new Has_Rep_Pragma function
29557 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29558 function with string.
29559 Use new Has_Rep_Pragma function.
29561 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes

29566 * errout.ads, errout.adb: (First_Sloc): New function
29568 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29569 check (-gnatyx) instead of being included as a redundant construct
29572 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29573 Style_Check_Order_Subprograms.
29575 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29576 stylesw.adb: Add Style_Check_Xtra_Parens
29578 * usage.adb: Add line for -gnatyx (check extra parens)
29580 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx

29583 Robert Dewar <dewar@adacore.com>
29585 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29586 discriminant of a constrained subtype, analyze the copy of the
29587 corresponding constraint, because in some cases it may be only
29588 partially analyzed.
29589 Removes long-lived ??? comments.
29591 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29592 handled controlled or secondary-stack expressions within the
29593 iteration_scheme of a loop.
29595 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29596 bounds that may contain functions calls, to prevent memory leaks when
29597 the bound contains a call to a function that uses the secondary stack.
29598 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29599 generate temporaries for loop bounds that might contain function calls
29600 that require secondary stack and/or finalization actions.
29602 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29603 selected component and the selector is overloadable (not just a
29604 function) treat as function call, Analyze_Call will disambiguate if
29606 (Analyze_Selected_Component): Do not generate an actual subtype for the
29607 selected component if expansion is disabled. The actual subtype is only
29608 needed for constraint checks.
29609 (Analyze_Allocator): If restriction No_Streams is set, then do
29610 not permit objects to be declared of a stream type, or of a
29611 composite type containing a stream.
29613 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29614 No_Streams no longer prohibits with'ing this package.
29616 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29617 discriminants, but the parent base has unknown discriminants, there is
29618 no discriminant constraint to inherit. Such a discrepancy can arise
29619 when the actual for a formal type with unknown discriminants is a
29620 similar private type whose full view has discriminants.
29621 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29622 do not permit objects to be declared of a stream type, or of a
29623 composite type containing a stream.
29625 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29627 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29628 protected operations.
29630 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29631 generated name, it complicates decoding in gdb and hinders debugging
29632 of protected operations.
29633 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29634 flag for the protected entry barrier function.
29635 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29636 flag for the protected entry function.

29642 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29643 Darwin-specific section.
29645 * lang-specs.h: Change the placement of the %1 marker.
29646 Works around the fact that gcc adds -fPIC by default under Darwin.
29648 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29650 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29651 type of the object with the packed array type, set the Analyzed flag
29652 on the object if it is an entity or simple indexed component, to avoid
29653 spurious type errors.
29655 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29657 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29658 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29659 separate line from the version message.
29661 2004-11-18 Ed Falis <falis@adacore.com>
29663 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29665 (init_float): Eliminate initialization of floating point status for
29666 AE653. The instructions have no effect for vThreads.
29668 2004-11-18 Vincent Celier <celier@adacore.com>
29670 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29671 gnatbind is invoked with -shared.
29673 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29675 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29676 for Detect_Blocking which is redundant with the check done within the
29677 procedure Protected_Single_Entry_Call.
29678 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29679 Detect_Blocking which is redundant with the check done within the
29680 procedure Protected_Single_Entry_Call.
29682 2004-11-18 Vincent Celier <celier@adacore.com>
29684 * makegpr.adb (Compile): Put the compiling switches (in package
29685 Compiler and on the command line) immediately after "-c", instead of
29686 at the end of the command line invocation of the compiler, when
29687 compiling a non-Ada file.
29688 (Build_Global_Archive): When there is no need to rebuild the archive,
29689 set Global_Archive_Exists, so that the archive is passed to the linker
29692 2004-11-18 Robert Dewar <dewar@adacore.com>
29693 Sergey Rybin <rybin@adacore.com>
29696 Remove extra paren check from list of checks for redundant constructs
29697 Add documentation of new -gnatyx style check (check extra parens)
29698 Remove paragraph about gnatelim debug options.
29700 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29701 objects rather than forbidding dependencies on the package Ada.Streams.
29703 * sinfo.ads: Add ??? note that we should document pragmas passed to
29706 * g-expect.ads: Fix a few typos in the comments.
29708 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>

29713 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29715 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29717 2004-11-07 Andreas Schwab <schwab@suse.de>
29719 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29721 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29724 * Makefile.in (darwin): Set soext to .dylib.
29726 2004-10-26 Vincent Celier <celier@gnat.com>
29727 Thomas Quinot <quinot@act-europe.fr>
29729 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29730 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29731 there is no use of GNAT.Sockets.Constants.
29732 Remove remaining pragma Import for C_Write
29733 Remove C_Read and C_Write from internal implementation unit
29734 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29735 the read and write functions from the system runtime library is fine
29736 on UNIX but won't work under Windows).
29738 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29739 (Check_Selector): Use C_Recv instead of C_Read.
29740 Selectors are the GNAT.Sockets abstraction to perform a select()
29741 call on a set of descriptors. To allow abortion of an ongoing
29742 select operation, some data is written to a dedicated socket that
29743 is always monitored.
29744 Under Windows, the write and read library functions cannot operate
29745 on sockets, so we need to use send and recv instead, which is portable
29746 across all supported platforms.
29748 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29749 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29750 (using the read and write functions from the system runtime library is
29751 fine on UNIX but won't work under Windows).
29753 2004-10-26 Nicolas Setton <setton@act-europe.fr>

29759 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29760 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29763 * Makefile.in: Add support for building shared libraries under Darwin.
29764 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29765 the low level EH init subprogram to be called from __gnat_initialize.
29767 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29768 indicates which options to pass to the archive indexer.
29770 * mlib-utl.adb: Add support for calling ranlib with additional
29771 options. This is needed for instance under Mac OS X.
29772 (Ranlib_Options): New global variable, used to store the potential
29773 options to pass to ranlib.
29774 (Ar): Use Ranlib_Options when spawning ranlib.
29775 (Initialize): Set the value of ranlib option.
29777 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29779 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29780 instead of 8K, to reflect the real potential needs for stack-checking
29783 2004-10-26 Pascal Obry <obry@gnat.com>
29785 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29787 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29788 Windows only the initial thread stack size can be set so it is good to
29789 start we a low stack size.
29790 The OS will adjust the size as needed.
29792 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29793 Nicolas Setton <setton@act-europe.fr>
29795 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29796 "__unix__" instead of "unix".
29797 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29798 sections were just mistakenly ignored. The former is
29799 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29800 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29801 of hpux. This prevents an unwanted definition of the symbol
29802 convert_addresses in adaint.o.
29804 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29806 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29807 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29809 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29811 * a-filico.ads, a-filico.adb: fix incorrect header.
29813 2004-10-26 Javier Miranda <miranda@gnat.com>
29815 * a-ststio.ads: Fix typo in identifier
29817 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29819 * sem_ch4.adb: Minor reformatting.
29821 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29823 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29824 enabled, check the result of unary and binary operations when the
29825 expression is the right-hand side of an assignment.
29827 2004-10-26 Vincent Celier <celier@gnat.com>
29829 * clean.adb (Delete): Do not output warnings when in quiet output and
29830 not in verbose mode.
29831 (Force_Deletions): New Boolean flag, defaulted to False
29832 (Delete): Only delete a file if it is writable, and when
29833 Force_Deletions is True.
29834 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29835 (Usage): Line for new switch -f
29836 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29839 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29841 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29842 JM type only if its size matches that of the wrapper. When a size is
29843 prescribed and the field is not aliased, remove the wrapper of a JM
29844 type only if the size is not greater than that of the packed array.
29845 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29848 2004-10-26 Geert Bosch <bosch@gnat.com>
29850 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29851 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29852 (Pred): Implement in terms of Succ.
29854 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29856 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29857 unchecked conversion is safe for in-place use if the expression of the
29858 conversion is safe.
29859 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29860 be expandable in place even if the aggregate does not come from source.
29861 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29862 designated object of an allocator in place, rather than building it
29863 first on the stack. The previous scheme forces a full copy of the array,
29864 and may be altogether unsusable if the size of the array is too large
29865 for stack allocation.
29867 2004-10-26 Robert Dewar <dewar@gnat.com>
29869 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29870 compares if the component is atomic.
29872 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29873 array assignment if the component type is atomic.
29875 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29876 Eric Botcazou <ebotcazou@act-europe.fr>
29878 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29879 is aliased and is a by_reference type, do not pass by copy.
29880 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29881 detect whether the call is in the right side of an assignment or
29882 the expression of an object declaration. Recurse on component
29883 association within aggregates.
29884 Call it in the condition that determines whether the temporary is
29885 necessary for correct stack-checking.
29887 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29889 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29890 RACW_Type, used in the PolyORB version.
29891 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29892 version and the GARLIC version.
29894 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29895 Rename RCI_Info to RCI_Locator for better consistency between the
29896 GARLIC and PolyORB versions of the distributed systems annex.
29897 (DSA_Implementation_Name): This enumeration lists the possible
29898 implementations of the Partition Communication Subsystem for the
29899 Distributed Systems Annex (DSA). The three available implementations
29900 are the dummy stub implementation (No_DSA), and two versions based on
29901 two different distribution runtime libraries: GARLIC and PolyORB. Both
29902 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29904 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29907 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29908 between the GARLIC and PolyORB versions of the distributed systems
29910 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29912 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29914 * gnat1drv.adb: Suppress calling the back end when
29915 Frontend_Layout_On_Target is true.
29917 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29919 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29920 Set_Read_Only): New subprograms.
29921 These new routines allow the user to set or unset the Owner execute
29922 and Owner write permission flags on a file.
29924 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29925 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29927 2004-10-26 Matthew Gingell <gingell@gnat.com>
29929 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29931 2004-10-26 Pascal Obry <obry@gnat.com>
29933 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29934 memory before the faulting page we properly test the process read
29935 access for this address using appropriate Win32 routine.
29936 (HPUX sections): guard with "__hpux__" instead of "hpux".
29938 2004-10-26 Robert Dewar <dewar@gnat.com>
29940 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29941 entry parameter if pragma Unreferenced set, since we do not properly
29942 handle the case of multiple parameters.
29944 2004-10-26 Vincent Celier <celier@gnat.com>
29946 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29947 (Ada_Objects_Path.Add): For a library project, add to the object path
29948 the library directory only if there is no object directory or if the
29949 library directory contains ALI files.
29950 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29952 2004-10-26 Vincent Celier <celier@gnat.com>
29954 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29955 extension of library projects.
29957 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29958 path defaults to ".:<prefix>/lib/gnat".
29959 (Parse): For an extending all project, allow direct import of a project
29960 that is virtually extended.
29962 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29963 the specified name is directly imported, return its ID. Otherwise, if
29964 an extension of this project is imported, return the ID of the
29967 2004-10-26 Robert Dewar <dewar@gnat.com>
29969 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29970 (Sub3): New procedure, used by Scaled_Divide
29971 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29972 correct more than one instance of failure to propagate carries
29974 (Double_Divide): Handle overflow case of largest negative number
29975 divided by minus one.
29977 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29978 the case of a quotient value out of range.
29981 2004-10-26 Robert Dewar <dewar@gnat.com>
29983 * s-bitops.adb (Bit_Eq): Remove redundant check.
29985 * s-bitops.ads: Minor comment updates
29986 Change some occurrences of Address to System.Address
29988 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29990 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29992 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29993 accessibility check to prefix that is a protected operation.
29995 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29997 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29998 empty, post message on stub.
30000 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30001 Javier Miranda <miranda@gnat.com>
30003 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30004 current instance appears within a unit that is directly in the context
30006 Used to determine whether the body of the instance should be analyzed
30007 immediately after its spec, to make its subprogram bodies available
30008 for front-end inlining.
30009 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30010 constraint is not allowed on the component type (AARM 12.5.3(3))
30012 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30014 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30015 'Storage_Pool): enhance, document & limit detection of non-sharable
30018 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30020 * s-pooglo.ads: Add more documentation now that this pool is properly
30023 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30025 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30026 or protected type with discriminants, do not constrain the
30027 corresponding record type if the subtype declaration has no
30028 discriminant constraints. This can be the case in source code, or in
30029 the subtype declaration created to rename an actual type within an
30032 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30034 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30035 different kind of stub (possibly wrong name for file), do not check
30037 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30038 includes call to some function that returns an unconstrained type, do
30041 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30043 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30044 appear in the code for the main unit. Dependencies among units in the
30045 context of the main unit are established when those other units are
30046 compiled. Otherwise spurious elaboration constraints can generate
30047 incorrect elaboration circularities.
30049 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30050 Ed Schonberg <schonberg@gnat.com>
30052 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30053 subprogram is called with a parameter that is not an object name. This
30054 situation arises for some cases of illegal code, which is diagnosed
30055 later, and in this case it is wrong to call Is_Aliased, as that might
30056 cause a compiler crash.
30057 (Explain_Limited_Type): Refine previous fix to include
30058 inherited components of derived types, to provide complete information.
30060 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30061 is the prival for a protected object.
30062 It is necessary to mark this entity as a variable, in addition to
30063 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30064 modified to avoid checking the Aliased flag on entities that are not
30065 objects. (Checking that flag for non-objects is erroneous and could
30066 lead to a compiler crash).
30068 2004-10-26 Robert Dewar <dewar@gnat.com>
30070 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30071 X_Frac = 0.5, then we know that the number X must be positive.
30072 (Succ): Remove the same redundant test, and also fix the primary test
30073 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30075 (Decompose): Add fuller comments to spec
30077 2004-10-26 Pascal Obry <obry@gnat.com>
30079 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30080 validity (process must have read access). Set to 0 in all other cases.
30081 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30082 violation on Win32.
30083 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30084 segmentation violation.
30086 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30088 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30089 whose type is a constructed subtype of an aliased object with an
30090 unconstrained nominal subtype, convert the actual to the constructed
30091 subtype before taking its address.
30093 2004-10-26 Vincent Celier <celier@gnat.com>
30095 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30096 (Is_Path_Name_Case_Sensitive): New function
30098 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30099 (Base_Name, Simple_Name, Current_Directory, Compose,
30100 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30103 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30104 Vasiliy Fofanov <fofanov@act-europe.fr>
30105 Vincent Celier <celier@gnat.com>
30107 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30108 "memory management issues" section and document some of the useful
30109 memory pools provided as part of the GNAT library.
30110 Remove "virtual" from declaration of A::method2 in
30111 the simple example of Ada/C++ mixed system.
30112 Library Projects may be virtually extended: their virtual extensions
30113 are not Library Projects.
30114 Added section on extending project hierarchies.
30116 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30118 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30120 (__gnat_portable_spawn): Remove const.
30122 * mingw32.h (MAXPATHLEN): Check for previous definition.
30124 2004-10-17 Matthias Klose <doko@debian.org>
30126 * gnatvsn.ads: Set gnat library version to 4.0.
30128 2004-10-05 Vincent Celier <celier@gnat.com>
30130 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30132 2004-10-04 Laurent Guerby <laurent@guerby.net>
30135 * Makefile.in: Define and use RANLIB_FLAGS.
30137 2004-10-04 Pascal Obry <obry@gnat.com>
30139 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30140 other x86 platforms).
30142 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30144 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30145 in general and triggers stack alignment adjustment for thread entry
30146 points on targets where this is necessary.
30148 2004-10-04 Bernard Banner <banner@gnat.com>
30151 * Makefile.in: Add section for powerpc linux
30152 Add variant i-vxwork-x86.ads
30154 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30156 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30158 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30159 table registration calls when need be. Ensures no reference to the crt
30160 ctors symbol are issued in the SJLJ case, which avoids possible
30161 undefined symbol errors in the case of modules to be statically linked
30164 2004-10-04 Javier Miranda <miranda@gnat.com>
30166 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30167 in-line the code corresponding to subprogram Analyze_Actuals. In
30168 addition, analyze the actuals only in case of subprogram call.
30170 2004-10-04 Ed Falis <falis@gnat.com>
30172 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30174 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30176 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30177 in the documentation.
30179 2004-10-04 Robert Dewar <dewar@gnat.com>
30181 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30183 (Analyze_Block_Statement): Add circuitry to detect following dead code
30184 (Check_Unreachable_Code): Handle case of block exit
30186 2004-10-04 Robert Dewar <dewar@gnat.com>
30188 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30189 (XMatchD): Avoid warning for Logic_Error call
30191 2004-10-04 Robert Dewar <dewar@gnat.com>
30193 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30194 consider expressions buried within a procedure actual to be an actual.
30195 This caused some blowups with uses of packed slices within a procedure
30198 2004-10-04 Robert Dewar <dewar@gnat.com>
30200 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30201 longer need to be initialized to zero.
30202 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30203 initialized to zero.
30205 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30206 considered valid, even if the representation is modular. That's correct
30207 now that we no longer initialize packed modular arrays to zero.
30209 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30210 suffixes. These are now documented as the only cases in which the
30211 debugger ignores outer records.
30212 Previously, the spec allowed arbitrary suffixes for this purpose.
30213 Change name of LJM to JM for packed array pad records
30214 Create separate section on packed array handling, and add a whole new
30215 set of comments to this section describing the situation with packed
30216 modular types and justification requirements depending on endianness.
30218 2004-10-04 Robert Dewar <dewar@gnat.com>
30220 * a-except.adb: Add a comment for last change
30222 * einfo.ads: Minor spelling correction in comment
30224 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30226 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30229 * sem_util.ads: Minor comment update
30231 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30233 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30234 Inline_Always when in Configurable_Run_Time mode.
30236 * sem_prag.adb (Process_Convention): If entity is an inherited
30237 subprogram, apply convention to parent subprogram if in same scope.
30238 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30239 when in Configurable_Run_Time mode.
30241 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30243 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30244 class_wide type after component list has been inherited.
30246 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30248 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30249 Denotes_Previous_Actual, to handle properly the case of a private
30250 actual that is also the component type of a subsequent array actual.
30251 The visibility status of the first actual is not affected when the
30252 second is installed.
30253 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30254 make fully recursive the treatment of formals of packages declared
30256 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30257 the above on exit from an instantiation.
30258 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30259 current instantiation which is now complete.
30260 (Analyze_Package_Instantiation): No instantiated body is needed if the
30261 main unit is generic. Efficient, and avoid anomalies when a instance
30262 appears in a package accessed through rtsfind.
30264 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30266 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30267 do not generate a declaration for a temporary if the call is part of a
30268 library-level instantiation.
30270 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30272 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30273 searching for a limited component to flag.
30275 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30276 expansion of Input, to account for the fact that the implicit call
30277 generated by the attribute reference must freeze the user-defined
30278 stream subprogram. This is only relevant to 'Input, because it can
30279 appear in an object declaration, prior to the body of the subprogram.
30281 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30282 expansion can proceed and further errors uncovered.
30283 (Minor clean up): Fix cases of using | instead of \ for continuation
30286 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30288 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30290 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30291 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30292 Use gcc_assert and gcc_unreachable.

30295 specified alignment before validating size.
30296 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30297 stripped-down declaration for the type of the inner field when making
30300 * utils.c (finish_record_type): Do not compute the size in units
30301 incrementally. Instead compute it once for the rep clause case.
30302 Use gcc_assert and gcc_unreachable.
30304 2004-10-04 Vincent Celier <celier@gnat.com>
30306 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30308 (Is_Valid_Path_Name): Take '/' as a directory separator.
30310 2004-10-04 Vincent Celier <celier@gnat.com>
30312 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30313 (Extended_Project) only if Extended_Project is defined, to avoid
30315 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30317 (Parse_Single_Project): Ditto.
30319 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30320 Add_To_Project_Path for virtual projects.
30322 2004-10-04 Vincent Celier <celier@gnat.com>
30324 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30327 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30328 parameter Options_2.
30330 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30331 Build_Dynamic_Library with an empty Options_2.
30333 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30336 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30337 directory separator, if any.
30338 (Gprmake): Do not allow mains on the command line for library projects.
30339 Do not attempt to link when the project is a library project.
30340 (Library_Opts): New table to store Library_Options.
30341 (Build_Library): If Library_Options is specified, pass these options
30342 when building a shared library.
30344 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30346 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30347 the end of this procedure now that the unlock operation was inserted
30350 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30352 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30353 corresponding to the Preallocated_Stacks flags in System.
30354 (Get_Target_Parameters): Including the processing for

30366 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30367 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30368 used to signal whether the compiler creates the required stacks and
30369 descriptors for the different tasks (when True) or it is done by the
30370 underlying operating system at run time (when False).
30371 It is initially set to False in all targets.
30373 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30374 if it is supported by the target.
30375 (Make_Task_Create_Call): Pass the stack address if it has been
30376 previously created. Otherwise pass a Null_Address.
30378 * snames.adb: Add _stack.
30380 * snames.ads: Add Name_uStack. Required to allow the expander to
30381 statically allocated task stacks.
30383 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30384 Stack_Address argument.
30385 Check that its value is equal to Null_Address because this target does
30386 not support the static stack allocation.
30388 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30390 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30393 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30395 * exp_dist.adb: Split declaration of asynchronous flag out of
30396 Add_RACW_Read_Attribute.
30397 Minor reformatting for better alignment with PolyORB version.
30398 Store the entity for the asynchronous flag of an RACW, rather than the
30399 expression, in the asynchronous flags table. This will allow this flag
30400 to be used in other subprograms beside Add_RACW_Read_Attribute.
30402 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30404 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30408 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30409 sockets constant MSG_NOSIGNAL (Linux-specific).
30410 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30411 all Send operations.
30412 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30413 from trigerring SIGPIPE.
30414 Rename components to avoid clash with Ada 2005 possible reserved
30416 (Check_Selector): When the select system call returns with an error
30417 condition, propagate Socket_Error to the caller.

30429 Change "pragma inline" to "pragma Inline" in information and error
30431 Minor reformatting.
30433 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30434 right way of doing things after all.
30435 (Freeze_Entity): For object, set Is_Public for imported entities
30436 unless there is an address clause present.
30438 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30440 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30441 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30442 ensures proper handling of types with rep clauses, which might have
30443 their TYPE_SIZE set already.
30445 2004-09-21 Robert Dewar <dewar@gnat.com>
30447 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30448 packed array types in both little- and big-endian cases. This change
30449 ensures that we no longer count on the unused bits being initialized
30450 for such types (and in particular ensures that equality testing will
30451 only read the relevant bits).
30452 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30453 These changes mean that we no longer need to initialize small packed
30455 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30456 optimization to an LJM field as to its parent field.
30458 * ada-tree.h, trans.c, utils.c, utils2.c:
30459 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30461 2004-09-20 Jan Hubicka <jh@suse.cz>
30463 * utils.c (gnat_finalize): Remove.
30464 (end_subprog_body): Directly call cgraph_finalize_function;
30465 do not lower the nested functions.
30467 2004-09-20 Robert Dewar <dewar@gnat.com>
30470 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30471 if an address clause is present, since that means that the Import
30474 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30476 * 5tsystem.ads: Removed, no longer used.

30479 Zack Weinberg <zack@codesourcery.com>
30481 * ada-tree.def: Use tree_code_class enumeration constants
30482 instead of code letters.

30500 an existing directory.
30501 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30502 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30503 Convert the result to File_Size.
30505 * prj.ads: (Project_Error): New exception
30507 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30508 Prj.Com, not from Osint.
30509 (Attrs, Package_Attributes): Tables moved to private part of spec
30510 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30512 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30513 Prj.Project_Error after call to Fail.
30514 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30515 Fail. Check that package name is not already in use.
30517 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30518 used by tools, not only by the project manager, and to indicate that
30519 exception Prj.Prj_Error may be raised in case of problem.
30520 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30522 (Attrs, Package_Attributes): Table instantiations moved from the body to
30523 the private part to be accessible from Prj.Attr.PM body.
30525 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30526 from new package Prj.Attr.PM.
30527 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30530 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30532 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30533 instead of Elaboration_Checks).
30535 * a-calend.adb: Minor reformatting

30578 pragmas recognized by GNAT.
30580 * gnat_rm.texi: Document pragma Detect_Blocking.
30582 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30583 raise Program_Error if called from a protected operation.
30585 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30586 the protected action nesting level.
30587 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30588 protected action nesting level.
30589 (Unlock): When pragma Detect_Blocking is active decrease the protected
30590 action nesting level.
30592 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30593 Protected_Action_Nesting.
30595 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30596 Common_ATCB record. It contains the dynamic level of protected action
30597 nesting for each task. It is needed for checking whether potentially
30598 blocking operations are called from protected operations.
30599 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30600 Detect_Blocking is active or not in the partition.
30602 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30603 raise Program_Error if called from a protected operation.

30612 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
30613 raise Program_Error if called from a protected operation, and increase
30614 the protected action nesting level.

30616 Program_Error if called from a protected operation, and increase the
30617 protected action nesting level.

30623 the protected action nesting level.
30624 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
30625 Program_Error if called from a protected operation, and increase the
30626 protected action nesting level.

30632 protected action nesting level.
30634 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30635 insertion of the statement raising Program_Error. The run time
30636 contains the required machinery for handling that.
30638 * sem_util.ads: Change comment associated to procedure
30639 Check_Potentially_Blocking_Operation.
30640 This procedure does not insert a call for raising the exception because
30641 that is currently done by the run time.
30643 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30645 * init.c: Add the global variable __gl_detect_blocking that indicates
30646 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30647 making the pragma available at run time.
30648 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30650 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30651 pragma Detect_Blocking is active.
30653 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30655 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30656 DB is found in the ali file. Any unit compiled with pragma
30657 Detect_Blocking active forces its effect in the whole partition.
30659 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30660 Detect_Blocking is active and delay is called from a protected
30663 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30664 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30665 Detect_Blocking is active (0 otherwise).
30666 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30667 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30670 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30672 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30673 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30676 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30677 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30678 Update API in placeholder implemetation of s-parint to reflect changes
30679 in distribution runtime library.
30681 * sem_ch3.adb (Expand_Derived_Record): Rename to
30682 Expand_Record_Extension.
30684 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30685 primitive operations of potentially distributed object types that have
30686 non-controlling anonymous access formals.
30688 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30690 New implementation of expansion for remote access-to-subprogram types,
30691 based on the RACW infrastructure.
30692 This version of sem_dist is compatible with PolyORB/DSA as well as
30695 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30696 Asynchrronous that applies to a remote access-to-subprogram type, mark
30697 the underlying RACW type as asynchronous.
30699 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30700 __gnat_using_gnu_linker to 1.
30702 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30703 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30704 GNAT.Perfect_Hash_Generators, and remove the empty
30705 GNAT.Perfect_Hash package.
30707 * atree.adb: Minor reformatting
30709 * exp_ch3.adb (Expand_Derived_Record): Rename to
30710 Expand_Record_Extension.
30711 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30712 a component declaration must remain attached at that point in the
30713 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30714 It is therefore necessary to take a copy of the expression when building
30715 the corresponding assignment statement in the init proc.
30716 As a side effect, in the case of a derived record type, we now see the
30717 original expression, without any rewriting that could have occurred
30718 during expansion of the ancestor type's init proc, and we do not need
30719 to go back to Original_Node.
30721 * exp_ch3.ads (Expand_Derived_Record): Rename to
30722 Expand_Record_Extension.
30724 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30725 Returns the RACW type used to implement a remote access-to-subprogram
30727 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30728 New subprograms. Used to create a proxy tagged object for a remote
30729 subprogram. The proxy object is used as the designated object
30730 for RAS values on the same partition (unless All_Calls_Remote applies).
30731 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30732 System.Partition_Interface.Get_Unique_Remote_Pointer.
30733 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30734 Renamed from Add_RAS_*_Attribute.
30735 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30737 New implementation of expansion for remote access-to-subprogram types,
30738 based on the RACW infrastructure.
30740 * exp_dist.ads (Copy_Specification): Update comment to note that this
30741 function can copy the specification from either a subprogram
30742 specification or an access-to-subprogram type definition.
30744 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30746 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30747 in an instance, between an explicit subprogram an one inherited from a
30748 type derived from an actual.
30750 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30751 add a polling call if the subprogram is to be inlined by the back-end,
30752 to avoid repeated calls with multiple inlinings.

31002 for a global aliased object with a variable size and an unconstrained
31003 nominal subtype, pretend there is no initializer if the one we have is
31004 incomplete, and avoid referencing an inexistant component in there. The

31032 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31033 discriminants that rename those of the parent, recover names of
31034 original discriminants for the constraint on the full view of the

31065 returning C.int, to avoid using a derived boolean type.
31067 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31096 ignore overflows on low and high bounds of an index to also account for
31097 differences in signedness between sizetype and gnu_index_subtype.
31098 These are as legitimate as the ones caused by a lower TYPE_PRECISION

35212 part has been scanned-out and it was present
35214 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
35216 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram

35277 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35279 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35280 executable name when not initialized. Otherwise, use its current value.
35282 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35283 initialize it to another executable name than the current one. This
35284 allows to configure paths for an executable name (gnatmake) different
35285 from the current one (gnatdist).
35287 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35289 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35290 current unit cannot be inlined if it appears in the body of a withed
35291 unit, to avoid order of elaboration problems in gigi.
35293 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35294 information for protected (wrapper) operation as well, to simplify gdb
35297 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35298 protected body, indicate that the entity for the generated spec comes
35299 from source, to ensure that references are properly generated for it.
35300 (Build_Body_To_Inline): Do not inline a function that returns a

35304 apply convention to homonyms that are declared explicitly.
35306 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35307 that renames an equality operator and the operands are overloaded,
35308 resolve them with the declared formal types, before rewriting as an
35311 2004-03-29 GNAT Script <nobody@gnat.com>

35334 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35336 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35337 attribute reference does not denote a subtype, it can be any
35338 expression that has a classwide type, potentially after an implicit
35339 dereference. In particular, the prefix can be a view conversion for
35340 a classwide type (for which Is_Object_Reference holds), but it can
35341 also be a value conversion for an access-to-classwide type. In the
35342 latter case, there is an implicit dereference, and the original node
35343 for the prefix does not verify Is_Object_Reference.
35345 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35346 conversion of a discriminant-dependent component of a mutable object
35349 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35351 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35352 inherited, has convention C, and has unconstrained array parameters,
35353 place the corresponding warning on the derived type declaration rather
35354 than the original subprogram.
35356 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35357 indication on renaming declaration, if formal has a box and actual
35360 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35361 determine whether to generate an implicit or explicit reference to
35362 the renamed entity.
35364 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35365 subprogram renaming comes from a defaulted formal subprogram in an
35368 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35370 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35371 value expressions to ensure that calls within a component definition
35372 will be checked (since those are evaluated during the record type's

35423 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35424 declaration for a child subprogram body that acts as a spec, indicate
35425 that the entity in the declaration needs debugging information.
35427 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35428 full view if the subtype is created for a constrained record component;
35429 gigi has enough information to construct the record, and there is no
35430 place in the tree for the declaration.
35432 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35433 serial number for the dummy body that is built for analysis, to avoid
35434 inconsistencies in the generation of internal names when compiling

35465 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35466 gnat_ug_wnt.texi: Regenerate.
35468 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35470 * ada-tree.h: Update copyright notice.
35471 Minor reformatting.
35473 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35475 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35476 as regular exception objects and not as mere integers representing the
35477 condition code. The latter approach required some dynamics to mask off
35478 severity bits, which did not fit well into the GCC table based model.
35479 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35480 exception data objects. We don't it and it would conflict with the other
35481 external symbol we have to generate for such exceptions.
35483 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35484 the special code for VMS exceptions, since these are now represented
35485 as regular exceptions objects.
35487 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35489 * decl.c (debug_no_type_hash): Remove.

35493 2004-03-19 Laurent Guerby <laurent@guerby.net>
35495 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35496 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35498 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35500 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

35515 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35516 Specific.Set instead of direct call to e.g pthread_setspecific.
35518 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35520 * adaint.c: Update comments.
35522 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35523 GNATLIB_SHARED for FreeBSD.
35525 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35527 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35528 When needed (stack checking) the stack size is retrieved
35529 from the VxWorks kernel.
35531 * Makefile.in: Flag -nostdinc is required when building the run time
35532 for avoiding looking for files in the base compiler.
35533 Add the VxWorks specific version of the package body for
35534 System.Stack_checking.Operations (5zstchop.adb).
35536 * Make-lang.in: Add the object file for
35537 System.Stack_Checking.Operations.
35539 * Makefile.rtl: Add object file for the package
35540 System.Stack_Checking.Operations.
35542 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35544 * s-stache.ads, s-stache.adb: Move the operations related to stack
35545 checking from this package to package System.Stack_Checking.Operations.
35546 This way, stack checking operations are only linked in the final
35547 executable when using the -fstack-check flag.
35549 2004-03-18 Doug Rupp <rupp@gnat.com>
35551 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35561 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35562 the procedures Add_To_Path_File.
35563 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35564 making sure that each directory is present only once and, for object
35565 dirs, when a directory already present is added, the duplicate is
35566 removed and the directory is always put as the last in the table.
35567 Write the path files at the end of these accumulations.
35569 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35570 Files_Htable for all sources.
35572 * prj-proc.adb (Process): Remove restrictions between not directly
35573 related extending projects.

35586 when the source contains only comments.
35588 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35590 * sem_warn.adb (Check_References): For a warning on a selected
35591 component that does not come from source, locate an uninitialized
35592 component of the record type to produce a more precise error message.
35594 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35596 * 3zsoccon.ads: Fix multicast options.

35604 pragma used for a private type.
35606 * lib-xref.adb (Generate_Reference): Do not generate warning if
35607 reference is in a different unit from the pragma Unreferenced.
35609 * 5vtpopde.adb: Minor reformatting
35610 Fix casing of To_Task_ID
35612 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35613 flag if we have an unchecked conversion to an access type in the same
35616 2004-03-15 Geert Bosch <bosch@gnat.com>
35618 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35619 imaginary parts, use Double precision throughout.
35621 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35622 we want to be able to compile run-time with -gnata for testing, but
35623 this may also be instantiated in user code that is compiled with -gnata.
35625 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35627 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35628 codes. Having a separate type for this is useful to enforce consistency
35629 throughout the various run-time units.
35630 (Exception_Data): Use Exception_Code for Import_Code.
35632 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35633 Natural and Integer in various places.
35634 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
35635 with the severity bits masked off.
35636 (Register_VMS_Exception): Handle the additional exception data pointer
35639 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35640 component, now reflected by an exported accessor.
35641 (is_handled_by): New routine to compute whether the propagated
35642 occurrence matches some handler choice specification. Extracted out of
35643 get_action_description_for, and expanded to take care of the VMS
35645 (get_action_description_for): Use is_handled_by instead of an explicit
35646 complex condition to decide if the current choice at hand catches the
35647 propagated occurrence.
35649 * raise.h (Exception_Code): New type for C.
35651 * rtsfind.ads (RE_Id, RE_Unit_Table): Add

35779 explicit dereference.
35780 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35781 of non-packed slices, since the dereference action generated by

35784 analyze and resolve the rewritten explicit dereference so it is seen
35786 (Insert_Dereference_Action): This procedure is now called only for the

36666 Let finish_record_type decide instead.
36667 Don't make a bitfield if the field is to be addressable.
36668 Always set a size for the field if the record is packed, to ensure the
36669 checks for bitfield creation are triggered.
36670 (finish_record_type): During last pass over the fields, clear
36671 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

36721 error when there are unusual characters (such as '!') in the paths.
36723 * Makefile.generic: When there are sources in Ada and the main is in
36724 C/C++, invoke gnatmake with -B, instead of -z.

36727 from VMS_Conversion.
36728 (Process_Argument): New procedure, extracted from VMS_Conversion. Add

37130 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37131 N_String_Literal node always references an E_String_Literal_Subtype
37132 entity. This may not be true in the future.
37133 (Possible_Bit_Aligned_Component): Move processing of
37134 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37136 * exp_ch6.adb (Expand_Thread_Body): Pick up

37141 (Type_May_Have_Bit_Aligned_Components): New function.

37181 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37182 ineffective elaborate all pragmas on non-visible packages (this
37183 happened when a renamed subprogram was called). Now the elaborate all
37184 always goes on the package containing the renaming rather than the one
37185 containing the renamed subprogram.
37187 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37188 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37214 -B is specified. Fail when there are only foreign mains in attribute

37249 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37250 all attributes, including read-only attribute.

37261 based on the new naming scheme.
37263 * gnatlink.adb (Process_Binder_File): Properly detect the new naming

37405 to __gnat_map_signal, imported from init.c to support
37406 signal -> exception mappings that depend on the vxWorks version.
37409 Created and exported __gnat_map_signal to support signal -> exception
37410 mapping that is dependent on the VxWorks version.

37443 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37444 bounds of a loop, create a separate block in order to generate proper
37445 cleanup actions to prevent memory leaks.
37447 * sem_res.adb (Resolve_Call): After a call to
37448 Establish_Transient_Scope, the call may be rewritten and relocated, in

37467 2003-12-08 Robert Dewar <dewar@gnat.com>
37469 * 7sintman.adb: Minor reformatting
37471 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37472 standard linker options to get standard libraries linked. We now plan
37473 to provide dummy versions of these libraries to match the appropriate
37474 configurable run-time (e.g. if a library is not needed at all, provide
37475 a dummy empty library).
37477 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37478 options (-L parameters and standard libraries). What we plan to do is
37479 to provide dummy libraries where the libraries are not required.
37481 * gnatbind.adb: Minor comment improvement
37483 2003-12-08 Javier Miranda <miranda@gnat.com>
37485 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37493 of aggregate with default initialized components.
37494 (Has_Default_Init_Comps): Improve implementation to recursively check
37495 all the present expressions.
37497 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37498 to indicate that the initialization call corresponds to a
37499 default-initialized component of an aggregate.
37500 In case of default initialized aggregate with tasks this parameter is
37501 used to generate a null string (this is just a workaround that must be
37502 improved later). In case of discriminants, this parameter is used to
37503 generate a selected component node that gives access to the discriminant
37506 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37507 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37508 allocated aggregates with default-initialized components.
37510 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37511 the box notation is used in positional aggregates.

37553 Process nodes N_Comment.
37555 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37556 without comments and there are some comments, set the flag
37557 Unkept_Comments to True.
37558 (Scan): If there are comments, set the flag Unkept_Comments to True and
37559 clear the comments.

37598 * sem_aggr.adb: Add dependence on Exp_Tss package
37599 Correct typo in comment
37600 (Resolve_Aggregate): In case of array aggregates set the estimated
37601 type of the aggregate before calling resolve. This is needed to know
37602 the name of the corresponding IP in case of limited array aggregates.
37603 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37604 in case of default initialized array components.
37606 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

37626 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37627 they are automatically generated by Make-lang.in and cause nothing but
37628 maintenance troubles.
37630 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37632 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37646 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37647 to ensure that the kernel fills in the interrupted context structure
37648 before calling a signal handler, which is necessary to be able to
37649 unwind past it. Update the copyright notice.
37651 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37653 * a-elchha.ads: New file.
37655 * a-elchha.adb: New default last chance handler. Contents taken from

37737 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
37738 included in HIE_NONE_TARGET_PAIRS.
37740 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37743 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37744 is legal in an instance, because legality is cheched in the template.
37747 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
37748 appplied to an unchecked conversion of a formal parameter.
37751 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

37765 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37766 so that the debugger can reliably access the value of the parameter,
37767 and therefore is able to display the exception name when an exception
37768 breakpoint is reached.

39107 Remove the test against being in No_Run_Time_Mode before generating a
39108 call to Register_Tag. It is redundant with the test against the
39109 availability of the function Register_Tag.

39125 information, check that the source exists and, if it does, that the path
39126 is the actual path of a source of a project.

41315 (title page): Remove date.
41316 (general) Add @./@: where approriate, and two spaces after the
41317 full stop at the end of a sentence. Use @samp markup when
41318 referring concrete lexical entities (keywords, attribute names
41319 etc.), and @syntax for ARM grammar elements. Use @r for English

41396 Add 2001 to copyright date
41398 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41399 need to force universal inlining for these cases.
41401 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41403 * s-taprob.adb: Minor clean ups so that this unit can be used in
41406 * exp_ch7.adb: Allow use of secondary stack in HI mode.

41430 the argument of an initialization procedure.
41432 * trans.c (tree_transform, case of arithmetic operators): If result
41433 type is private, the gnu_type is the base type of the full view,
41434 given that the full view itself may be a subtype.
41436 2001-12-17 Robert Dewar <dewar@gnat.com>
41438 * sem_res.adb: Minor reformatting

41704 2001-12-17 Laurent Pautet <pautet@gnat.com>
41707 Fix comment of Shutdown_Socket and Close_Socket. These functions
41708 should not fail silently because if they are called twice, this
41709 probably means that there is a race condition in the user program.
41710 Anyway, this behaviour is consistent with the rest of this unit.
41711 When an error occurs, an exception is raised with the error message
41712 as exception message.

43046 instead of the previous simple checksum algorithm.
43047 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43048 (Set_Source_Table): idem.
43051 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43052 instead of simple checksum.
43053 (CRC_Match): new function.
43054 (CRC_Error): new constant.
43056 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43057 a CRC now and not a simple checksum. A CRC uses lower-case hex
43058 letters, fixes ambiguity in parsing.
43060 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43061 is what this variable will store.
43063 * bcheck.adb: Change reference to chechsum in comments by CRC.
43064 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43065 rename All_Checksum_Match to All_CRC_Match. Change due to API
43066 renaming since now GNAT does not use a simple checksum but a
43067 CRC using GNAT.CRC32.
43069 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43070 now and not anymore a simple checksum.
43072 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
43075 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
43078 (Restore_Scan_State): rename Checksum to CRC.

43083 (Checksum): rename to CRC.
43084 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
43086 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
43087 GNAT.CRC32). Update copyright notice.
43089 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
43090 GNAT.CRC32). Update copyright notice.
43093 (Accumulate_Checksum): removed.
43094 (Update): new procedure. Add a wide-character into the CRC.
43097 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
43098 (Load_File): fix initialization of S (change Source_Checksum to
43101 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
43102 Source_CRC in S initialization.
43104 * sinput.adb (Source_Checksum): renamed to Source_CRC.
43106 * sinput.ads (Source_Checksum): renamed to Source_CRC.
43107 Update comments for the CRC.
43109 * types.adb (Hex): Use lowercase for the letter part.
43111 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43112 for a word. This is currently used only for CRC. In previous version,
43113 the checksum was using a representation with all letter being
43114 upper-case. With the new implementation (using CRC) we do not remove
43115 the 32th bit of the CRC, so we can have an upper-case starting letter
43116 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43117 It is ambigous since the CRC was optional and could be followed by
43118 options like EB, EE. So now this routines uses lower-case letter for
43119 the hexadecimal representation. Strange enough only lower case letters
43120 where checked in Scan_ALI (even if this was not a possible case).
43122 * gnatvsn.ads (Library_Version): changed to 3.15a.
43124 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43127 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43130 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43131 Add 2001 to copyright notice
43132 (Accumulate_Checksum): Modify to use System.CRC32.
43134 * ali-util.ads: Redo changes of previous revision to continue to use
43135 the word Checksum. Add 2001 to copyright notice.
43137 * ali.adb: Undo some of previous changes, not needed.
43138 Keep the change for lower case letters in the checksum.
43140 * ali.ads: Undo previous change not needed.
43142 * bcheck.adb: Undo most of previous change, not needed.
43143 But do use Checksums_Match for checksum comparison.
43145 * gnatls.adb: Undo most of previous change, not needed.
43146 But do use Checksums_Match for comparing checksums.
43148 * lib-load.adb: Undo previous change, not needed.
43150 * lib-writ.adb: Undo previous change, not needed.
43152 * lib-writ.ads: Document that checksums use lower case,
43153 not upper case letters.

43157 * scans.ads: Undo previous change, not needed.
43159 * scn-nlit.adb: Undo previous changes, not needed.
43161 * scn-slit.adb: Undo previous change, not needed. Fix header format.

43166 Remove other changes of previous revision.
43168 * sinput-p.adb: Undo previous change, not needed.
43170 * sinput.adb: Undo previous change, not needed.
43172 * sinput-l.adb: Undo previous change, not needed.
43174 * sinput.ads: Undo previous change, not needed. Keep only comment
43175 on new checksum algorithm
43177 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
43178 Also remove a-tags and a-stream from GNAT sources.
43180 * ali.adb (Scan_ALI): fix typo introduce in latest check-in.
43182 * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
