253 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
254 care of access to class-wide interface types plus removal of bizarre

303 for unsupported configurations; use it on VMS targets instead of the
305 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
306 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
307 used by VxWorks targets to have access to task-specific data and be
308 able to extract the stack boundaries for stack checking.

352 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
353 association for an access component, add an association with null as
354 the expression. Remove testing for array subtypes and the setting in

356 inclusion of an association for null-initialized arrays. Collapse
357 condition that tests for array subtypes into just a test of
358 Is_Partially_Initialized_Type (which already covers arrays anyway).

376 (Analyze_Allocator): When the designated type of an unconstrained
377 allocator is a record with unknown discriminants or an array with
378 unknown range bounds, emit a detailed error message depending on the

553 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
554 or one (enabled) depending on the presence of binder switch "-y".
555 (Gen_Adainit_C): Add code to generate the declaration of external int
556 __gl_leap_seconds_support. Set is value to zero (disabled) or one
557 (enabled) depending on the presence of binder switch "-y".
559 * init.c: Add __gl_leap_seconds_support to the list of global values
560 computed by the binder.

569 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
571 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
572 function which can be called by the debugger to interrupt the tasks of
573 an Ada application asynchronously, as needed on VxWorks.
574 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
576 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
577 renamed from Stop_All_Tasks. Update comments.
578 (Stop_All_tasks): New function declaration.
580 2007-09-26 Olivier Hainque <hainque@adacore.com>
582 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
583 #include <utime.h> and #define GCC_RESOURCE_H before
584 #include <sys/wait.h>.
585 Add more protections in __gnat_translate_vms.
587 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
588 #include <sys/wait.h>.

608 Eric Botcazou <ebotcazou@adacore.com>
611 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
612 indirection added to the HT_Link component of the TSD. This is required
613 to statically allocate the TSD.
616 Minor reordering of the declarations in the private part. Required to
617 add a level of indirection to the contents of the TSD component HT_Link.
618 This is required to statically allocate the TSD.
620 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
621 Is_Statically_Allocated set from constant objects.
622 Do not make exported constants created by the compiler volatile.
623 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
626 * trans.c (Identifier_to_gnu): For constants, unshare initializers
627 before returning them.
629 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
630 public part of the package.
631 (Make_DT): Move HT_Link component out of the TSD record. For this
632 purpose Make_DT now declares a separate object that stores the
633 HT_Link value, and initializes the TSD component with the address
634 of this new object. The addition of this level of indirection is
635 required to statically allocate the TSD because the TSD cannot
636 have variable components.
637 (Expand_Interface_Conversion): Improve the expanded code.
638 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
640 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
641 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
642 if we are building static dispatch tables then we must not generate
643 extra code to register the primitive because the dispatch table will
644 be built at the end of the library package; otherwise we notify that
645 we cannot build the static dispatch table.
647 2007-09-26 Robert Dewar <dewar@adacore.com>
649 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

664 for thunks associated with interface types.
666 * einfo.ads: Improve documentatation of Is_Internal
667 (Is_Thunk): New attribute applicable to subprograms. True for thunks
668 associated with interface types.
669 Extensive comment fixes regarding flags that appear in all entities. The
670 documentation is now consistent for all such flags (there were a number
671 of errors in the documentation in this regard).
673 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
675 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
676 of these procedures are passed a function call that already has
677 build-in-place actuals (testing new flag
678 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
679 the case where processing continues.
680 (Expand_Call): If the call is generated from a thunk body then we
681 propagate the extra actuals associated with the accessibility
682 level of the access type actuals.
684 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
685 of each extra formal of a protected operation to reference the
686 corresponding extra formal of the subprogram denoted by the
687 operation's Protected_Body_Subprogram.
689 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
690 N_Function_Call nodes.
692 2007-09-26 Robert Dewar <dewar@adacore.com>
694 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
696 * debug.adb: Add d.s flag.
698 2007-09-26 Gary Dismukes <dismukes@adacore.com>
700 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
701 debug variable so that it won't be initialized when pragma
702 Initialize_Scalars is in effect.
704 2007-09-26 Gary Dismukes <dismukes@adacore.com>
706 * freeze.adb (Freeze_Entity): Remove check for preelaborable
707 initialization of a full view. This is moved to
708 Analyze_Package_Specification.
710 * sem_ch7.adb (Analyze_Package_Specification): Add check for
711 preelaborable initialization of a full view in entity loop.
712 (Uninstall_Declarations): If entity is a use-visible compilation unit,
713 its child units are use-visible only if they are visible child units.
715 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
716 whether an expression can be used within a type declaration that
717 requires preelaborable init.
718 (Check_Components): Replace inline code that does partial checking for
719 preelaborable default expressions with call to
720 Is_Preelaborable_Expression.
721 (Has_Preelaborable_Initialization): In the case of a generic actual
722 subtype, (that is, Is_Generic_Actual is True), return the result of
723 applying Has_Preelaborable_Initialization to the generic actual's base
726 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
728 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
729 call to Jan_1_Day _Of_Week to optimize its performance.
730 (Is_Leap): Move the routine to the scope of Week_In_Year.
731 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
732 weekday on which January 1 falls of Year - 1 and Year + 1. This function
733 avoids calling Time_Of and Split, thus making it more efficent.
734 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
736 * g-calend.ads (Week_In_Year): Change comment to reflect new
739 2007-09-26 Emmanuel Briot <briot@adacore.com>
741 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
742 Command_Line): New types
743 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
744 support for defining how switches can be grouped on a command line (as
745 is the case for -gnatw... for GNAT), and how simple switches can be
746 used as aliases for more complex switches (-gnatwa is same as
748 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
749 (Start, Current_*): New subprograms
750 Added support for parsing an array of strings in addition to the real
752 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
753 be moved from the body to the private part of the spec.
754 (*): All subprograms now have an extra parameter with default value to
755 specify which parser should be used. For backward compatibility, it
756 defaults to parsing the command line of the application. They were also
757 modified to properly handle cases where each of the argument does not
758 start at index 1 (which is always true for Ada.Command_Line, but not
759 when processing any Argument_List).
760 (Free): New subprogram
761 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
762 Argument): New subprograms
763 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
764 special characters like ':', '=',... are now handled in a single place,
765 which makes the code more extensible eventually.
766 (Getopt, Full_Switch): When the switch was returned as part of the
767 special character '*', make sure it is prepended by the switch character
768 ('-' in general), so that the application knows whether "foo" or "-foo"
769 was specified on the command line.
771 2007-09-26 Florian Villoing <villoing@adacore.com>
773 * g-dirope.adb (Remove_Dir): In case we are removing directories
774 recursively, make sure that if an exception is raised during the
775 processing, the current working directory is reset to its initial
776 value before propagating the exception.
778 2007-09-26 Vincent Celier <celier@adacore.com>
780 * gnatbind.adb: If there are several ALI files specified and there is
781 a main program to bind, the first ALI is expected to contain the main
782 subprogram and the names of the binder generated files will be derived
783 from the first ALI file name.
784 (Gnatbind): Fix insertion character in invocation of Error_Msg
786 2007-09-26 Vincent Celier <celier@adacore.com>

793 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
794 information about each of its index types, following the type
795 reference for its component type.

799 * make.adb: (Kill): New procedure (__gnat_kill imported)
800 (Running_Compile, Outstanding_Compiles): Global variables that
801 were previously local to procedure Compile_Sources.
802 (Sigint_Intercepted): Send signal SIGINT to all outstanding
803 compilation processes.

810 2007-09-26 Vincent Celier <celier@adacore.com>
812 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
814 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
815 Replace components Compiler_Min_Options and Binder_Min_Options with
816 Compiler_Required_Switches and Binder_Required_Switches in record
818 Remove components Default_Language and Config in Project_Tree_Data,
821 * prj-attr.adb: New attributes Required_Switches (<language>) in
822 packages Compiler and Binder.
824 * prj-nmsc.adb: Major rewrite of the processing of configuration
825 attributes for gprbuild. No impact on GNAT tools.
827 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
828 process configuration attributes: this is done in Prj.Nmsc.Check.
829 (Recursive_Process): Make a full copy of packages inherited from project
830 being extended, instead of a shallow copy.
831 (Process_Project_Tree_Phase_1): New procedure

1046 * exp_disp.adb (Make_Tags/Make_DT): Replace previous code
1047 importing/exporting the _tag declaration by new code
1048 importing/exporting the dispatch table wrapper. This change allows us

1162 Thomas Quinot <quinot@adacore.com>
1164 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
1165 create an abstract subprogram in the case of 'Input. For 'Output we now
1166 create a real spec/body when the type is abstract, since it can
1167 potentially be called.
1168 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
1169 body for 'Output when the type is abstract (only the creation of the
1170 body for 'Input is excluded when the type is abstract).
1171 (Stream_Operation_OK): Add an additional condition in the return
1172 statement, so that False will be returned for TTS_Stream_Input if the
1173 associated tagged type is an abstract extension. Add comments for
1175 (Expand_N_Object_Declaration): For the case of a shared passive
1176 variable, insert init proc call only after the shared variable
1177 procedures have been processed, because the IP call needs to undergo
1178 shared passive variable reference expansion, which requires these
1179 procedures to be available (and elaborated).

1188 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
1189 given a box association, the type of the component is discriminated,
1190 and the value of the discriminant is the discriminant of the enclosing
1191 type, retrieve its value from the aggregate itself, where it must have
1194 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
1195 to remove other spurious ambiguities on arithmetic operations involving
1196 literals and addresses, on systems where Address is a visible integer
1197 type, when the operator is called in functional notation.
1198 (Try_Primitive_Operation): Within an instance, a call in prefixed form
1199 is legal when the types match, even if the operation is currently
1202 2007-09-10 Ed Schonberg <schonberg@adacore.com>
1204 * sem_ch12.adb (Build_Local_Package): A formal package with no
1205 associations is legal if all formals have defaults. It is not

1241 the N_Indexed_Component case.
1242 <N_Indexed_Component>: Fall through to above case.

1324 (Write_Entity_Flags): Write the status of flag Is_Raised.
1325 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
1326 spurious ambiguities when integer literals appear in the context of an
1327 address type that is a visible integer type.
1329 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
1330 exceptions never being raised.
1331 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

1384 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
1385 string, and the right operand is a string literal (the case of "" &

1389 * stringt.adb (Store_String_Chars): Optimize by growing the
1390 String_Chars table all at once, rather than appending characters one by
1392 (Write_String_Table_Entry): If the string to be printed is very long,
1393 just print the first few characters, followed by the length. Otherwise,
1394 doing "pn(n)" in the debugger can take an extremely long time.
1396 * sem_prag.adb (Process_Interface_Name): Replace loop doing

1416 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
1417 flag, for effiency. It is called when analyzing arithmetic operators
1418 and also for actuals in calls that are universal_integers. The flag is
1419 set for the predefined type address, and for any type or subtype
1422 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
1423 Universal_Integer, when the formal is a descendent of address and the
1424 call appears in user code.

1487 * misc.c (gnat_type_max_size): Constify.
1489 2007-08-16 Gary Dismukes <dismukes@adacore.com>
1491 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
1492 associated with Standard_Debug_Renaming_Type, to be used as the type of
1493 the special variables whose names provide debugger encodings for
1494 renaming declarations.
1496 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
1497 (Set_Debug_Renaming_Link): Change to set Node25.
1498 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
1499 (Write_Field25_Name): Add case for E_Variable to output
1500 "Debug_Renaming_Link".
1501 (Write_Field23_Name): Correct the output string for "Limited_View".
1503 * exp_dbug.adb: Add with and use of Tbuild.
1504 (Debug_Renaming_Declaration): Replace creation of an enumeration type
1505 and literal with creation of a variable of type
1506 Standard_Debug_Renaming_Type whose name encodes both the renamed object
1507 and the entity of the renaming declaration.
1508 (Qualify_Entity_Name): Add the delayed qualification of the entity name
1509 part of the name of a variable that has a Debug_Renaming_Link.
1511 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
1512 special type to be associated with variables that provide debugger

1516 Ed Schonberg <schonberg@adacore.com>
1517 Javier Miranda <miranda@adacore.com>
1519 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
1520 ancestor part given by an aggregate to test for an unchecked conversion,
1521 since this can occur in some cases when the ancestor part is a function
1522 call, and we don't want to fall into the recursive call to this
1523 procedure in that case.
1525 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
1526 stream attributes on limited types to account for user-specified
1527 attributes as well as whether Input (resp. Output) becomes available
1528 due to Read (resp. Write) being available for the type. Change Boolean
1529 variable to the more accurate name
1530 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
1531 double-"not" predicate at beginning of return statement to more
1532 understandable form.
1534 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
1535 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
1536 in a block statement and use that as the first statement of the
1537 expanded return rather than incorrectly using the handled sequence as
1538 the first statement.
1540 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
1541 operation, generate an explicit freeze node for it rather than
1542 generating extra formals, to ensure that gigi has the proper order of
1543 elaboration for anonymous subtypes in the signature of the subprograms.
1544 (Build_In_Place_Formal): Move assertion to beginning of loop.
1545 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
1546 applied to a function call (occurs for some cases of 'Input).
1547 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
1548 applied to a function call (occurs for some cases of 'Input).
1550 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
1551 2005, generate an extended return statement enclosing the result object
1554 * freeze.adb (Freeze_Record_Type): Extend the current management of
1555 components that are access type with an allocator as default value: add
1556 missing support to the use of qualified expressions of the
1557 allocator (which also cause freezing of the designated type!)
1558 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
1559 dispatching operation, since extra formals may be needed by calls to
1560 build-in-place functions (such as stream 'Input).
1562 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
1563 formals for 'Constrained and accessibility level in the case of a
1564 predefined dispatching operation.
1566 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
1567 point, no need to find the parent node.
1569 2007-08-16 Javier Miranda <miranda@adacore.com>
1571 * exp_attr.adb (Attribute_Priority): Add missing support for entries
1574 2007-08-16 Javier Miranda <miranda@adacore.com>
1576 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
1577 is not really required and can introduce regression with the debugger.
1578 The original problem is fixed with the patch written for checks.adb.
1580 2007-08-16 Thomas Quinot <quinot@adacore.com>
1582 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

1587 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
1588 Including_Non_Switch set to False.
1589 (Gnatmake): For the compiler, call Test_If_Relative_Path with
1590 Including_Non_Switch set to False.
1592 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
1593 parameter Including_Non_Switch, defaulted to True. When
1594 Including_Non_Switch is False, options that are not switches and
1595 appear as relative path are not converted to absolute paths.

1599 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
1602 * Make-lang.in: Update dependencies

1607 currently inspected is a selected component, retrieve the entity of
1609 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
1610 from the immediate ancestor of Main_Unit_Entity.
1611 (Install_Limited_Withed_Unit): Do not install the limited view of
1612 package P if P is reachable through an ancestor chain from package C
1613 and C also has a with clause for P in its body.
1614 (Has_Limited_With_Clause): New routine.
1615 (Has_With_Clause): New routine.
1617 2007-08-16 Ed Schonberg <schonberg@adacore.com>
1619 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
1620 generic for an enclosing instance is a global reference, even though
1621 its scope is the enclosing instance.
1623 2007-08-16 Gary Dismukes <dismukes@adacore.com>
1624 Javier Miranda <miranda@adacore.com>
1626 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
1627 initialize a limited object.
1628 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
1630 Make sure Has_Complex_Representation is inherited by derived type.

1634 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
1637 2007-08-16 Ed Schonberg <schonberg@adacore.com>
1639 * sem_disp.adb (Check_Dispatching_Operation): If the operation
1640 implements an operation inherited from a progenitor interface, verify
1641 that they are subtype-conformant.

1644 Bob Duff <duff@adacore.com>
1645 Nicolas Setton <setton@adacore.com>
1647 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
1648 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
1649 the statement which is being resolved comes from a predefined library
1650 unit, all non-predefined library interpretations are skipped.
1651 (Resolve_Op_Concat): If string concatenation was folded in the parser,
1652 but the "&" is user defined, give an error, because the folding would
1655 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
1656 the parser has folded a long sequence of concatenations of string
1659 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
1660 and "JMP_BUF" variables as artificial.
1661 (N_String_Literal): Do not use alloca for very long string literals. Use
1662 xmalloc/free instead. Otherwise the stack might overflow.
1664 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
1667 2007-08-16 Vincent Celier <celier@adacore.com>

1670 are not put in the -cargs section when using GNAT COMPILE.
1672 2007-08-16 Robert Dewar <dewar@adacore.com>
1674 * gnat_ugn.texi: Add note on preprocessing (output file not written)
1676 2007-08-16 Thomas Quinot <quinot@adacore.com>

1704 switch -gnatyS. Enable -gnatyS in GNAT style check mode
1706 2007-08-14 Robert Dewar <dewar@adacore.com>
1707 Ed Schonberg <schonberg@adacore.com>
1709 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
1710 Suppress unmodified in-out parameter warning in some cases
1711 This patch is a also fairly significant change to the way suppressible
1714 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
1715 needed for access to concurrent record types generated by the expander.
1716 (Generate_Range_Check): When generating a temporary to capture the
1717 value of a conversion that requires a range check, set the type of the
1718 temporary before rewriting the node, so that the type is always
1719 properly placed for back-end use.
1720 (Apply_Float_Conversion_Check): Handle case where the conversion is
1722 (Get_Discriminal): Code reformatting. Climb the scope stack looking
1723 for a protected type in order to examine its discriminants.

1726 Gary Dismukes <dismukes@adacore.com>
1727 Ed Schonberg <schonberg@adacore.com>
1728 Thomas Quinot <quinot@adacore.com>
1730 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
1731 a-stwisu.adb, a-strsup.adb: Fix warnings for range
1732 tests optimized out.
1734 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
1735 (Get_Allocator_Final_List): For the case of an anonymous access type
1736 that has a specified Associated_Final_Chain, do not go up to the
1738 (Expand_N_Type_Conversion): Test for the case of renamings of access
1739 parameters when deciding whether to apply a run-time accessibility
1741 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
1742 aggregate code before allocator, and ahead of declaration for
1743 temporary, to prevent access before elaboration when the allocator is
1744 an actual for an access parameter.
1745 (Expand_N_Type_Conversion): On an access type conversion involving an
1746 access parameter, do not apply an accessibility check when the
1747 operand's original node was an attribute other than 'Access. We now
1748 create access conversions for the expansion of 'Unchecked_Access and
1749 'Unrestricted_Access in certain cases and clearly accessibility should
1750 not be checked for those.
1752 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
1753 includes a type conversion of a packed component that has been expanded,
1754 recover the original expression for the object, and use this expression
1755 in the post-call assignment statement, so that the assignment is made
1756 to the object and not to a back-end temporary.
1757 (Freeze_Subprogram): In case of primitives of tagged types not defined
1758 at the library level force generation of code to register the primitive
1759 in the dispatch table. In addition some code reorganization has been
1760 done to leave the implementation clear.
1761 (Expand_Call): When expanding an inherited implicit conversion,
1762 preserve the type of the inherited function after the intrinsic
1763 operation has been expanded.
1765 * exp_ch2.ads, exp_ch2.adb
1766 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
1767 of an entry formal appearing in an assignment statement does not assign
1769 (Expand_Current_Value): Instead of calling a routine to determine
1770 whether the prefix of an attribute reference should be optimized or
1771 not, prevent the optimization of such prefixes all together.
1773 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
1774 component whose prefix is known to be of an access type is an implicit
1775 dereference and does not assign to the prefix.
1777 2007-08-14 Ed Schonberg <schonberg@adacore.com>
1778 Robert Dewar <dewar@adacore.com>
1780 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
1781 itype is visited, make an entry into table to link associated node and
1783 Add comments and correct harmless error in Build_NCT_Hash_Tables
1784 (Array_Aggr_Subtype): Associate each itype created for an index type to
1785 the corresponding range construct, and not to the aggregate itself. to
1786 maintain a one-to-one correspondence between itype and its associated
1787 node, to prevent errors when complex expression is copied.
1788 Fix mishandling of multiple levels of parens
1790 * sem_aggr.adb: Create a limited view of an incomplete type, to make
1791 treatment of limited views uniform for all visible declarations in a
1792 limited_withed package.
1793 (New_Copy_Tree): If hash table is being used and itype is visited,
1794 make an entry into table to link associated node and new itype.
1795 (Resolve_Record_Aggregate): Do not add an others box association for a
1796 discriminated record component that has only discriminants, when there
1797 is a box association for the component itself.
1799 * par-ch4.adb: Fix mishandling of multiple levels of parens
1801 2007-08-14 Robert Dewar <dewar@adacore.com>
1803 * comperr.adb: Fix problem with suppressing warning messages from gigi

1806 errout.adb (Write_Eol): Remove trailing spaces before writing the line
1807 (Write_Eol_Keep_Blanks): New procedure to write a line, including
1808 possible trailing spaces.
1809 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
1810 Fix problem with suppressing warning messages from back end
1811 Improve handling of deleted warnings
1814 Fix problem with suppressing warning messages from back end
1815 Handle setting of Static_Dispatch_Tables flag.
1818 Fix problem with suppressing warning messages from back end

1834 Javier Miranda <miranda@adacore.com>
1835 Gary Dismukes <dismukes@adacore.com>
1837 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
1838 to make treatment of limited views uniform for all visible declarations

1842 attribute with constants.
1843 (Write_Field26_Name): Handle attribute Related_Interface in constants.
1844 Warn on duplicate pragma Preelaborable_Initialialization
1846 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
1847 generation of a freezing node to ensure proper management of null
1848 excluding access types in the backend.
1849 (Create_Extra_Formals): Test base type of the formal when checking for
1850 the need to add an extra accessibility-level formal. Pass the entity E
1851 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
1852 originally being done in a couple of cases), to ensure that the
1853 Extra_Formals list gets set on the entity E when the first entity is
1855 (Conforming_Types): Add missing calls to Base_Type to the code that
1856 handles anonymous access types. This is required to handle the
1857 general case because Process_Formals builds internal subtype entities
1858 to handle null-excluding access types.
1859 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
1860 functions that need it, even when not marked Requires_Overriding.
1861 Improve warnings for in out parameters
1862 (Analyze_Function_Return): Warn for disallowed null return
1863 Warn on return from procedure with unset out parameter
1864 Ensure consistent use of # in error messages
1865 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
1866 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
1867 the implicit conversion of the expression done for anonymous access
1868 types. This is required to generate the code of the null excluding
1869 check (if required).
1871 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
1872 A formal parameter is never publicly referenceable outside of its body.
1873 (Check_References): For an unreferenced formal parameter in an accept
1874 statement, use the same warning circuitry as for subprogram formal
1876 (Warn_On_Unreferenced_Entity): New subprogram, taken from
1877 Output_Unreferenced_Messages, containing the part of that routine that
1878 is now reused for entry formals as described above.
1879 (Goto_Spec_Entity): New function
1880 (Check_References): Do not give IN OUT warning for dispatching operation
1881 Improve warnings for in out parameters
1882 (Test_Ref): Check that the entity is not undefinite before calling
1883 Scope_Within, in order to avoid infinite loops.
1884 Warn on return from procedure with unset out parameter
1885 Improved warnings for unused variables

1891 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
1892 (Expand_N_Attribute_Reference): Further unify the handling of the
1893 three forms of access attributes, using common code now for all three
1894 cases. Add a test for the case of applying an access attribute to
1895 an explicit dereference when the context is an access-to-interface
1896 type. In that case we need to apply the conversion to the prefix
1897 of the explicit dereference rather than the prefix of the attribute.
1898 (Attribute_Version, UET_Address): Set entity as internal to ensure
1899 proper dg output of implicit importation.
1900 (Expand_Access_To_Type): Removed.
1901 (Expand_N_Attribute_Reference): Merge the code from the three cases
1902 of access attributes, since the processing is largely identical for
1903 these cases. The substantive fix here is to process the case of a
1904 type name prefix (current instance case) before handling the case
1905 of interface prefixes.

1909 Javier Miranda <miranda@adacore.com>
1910 Robert Dewar <dewar@adacore.com>
1912 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
1913 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
1914 type that is an anonymous access to controlled object, establish
1915 an associated finalization chain to avoid corrupting the global
1916 finalization list when a dynamically allocated object designated
1917 by such a component is deallocated.
1918 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
1919 functions that need it, even when not marked Requires_Overriding.
1920 (Initialize_Tag): Replace call to has_discriminants by call to
1921 Is_Variable_Size_Record in the circuitry that handles the
1922 initialization of secondary tags.
1923 (Is_Variable_Size_Record): New implementation.
1924 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
1925 Suppress_Initialization pragma for a derived type.
1926 (Is_Variable_Size_Record): New subprogram.
1927 (Build_Offset_To_Top_Functions): New implementation that simplifies the
1928 initial version of this routine and also fixes problems causing
1929 incomplete initialization of the table of interfaces.
1930 (Build_Init_Procedure): Improve the generation of code to initialize the
1931 the tag components of secondary dispatch tables.
1932 (Init_Secondary_Tags): New implementation that simplifies the previous
1933 version of this routine.
1934 (Make_DT): Add parameter to indicate when type has been frozen by an
1935 object declaration, for diagnostic purposes.
1936 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
1937 diagnose attemps to freeze a subprogram when some untagged type of its
1938 profile is a private type whose full view has not been analyzed yet.
1939 (Freeze_Array_Type): Generate init proc for packed array if either
1940 Initialize or Normalize_Scalars is set.
1941 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
1942 constructing the new profile, copy the null_exclusion indicator for each
1943 parameter, to ensure full conformance of the new body with the spec.
1945 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
1946 Create wrappers for constructor functions that need it, even when not
1947 marked Requires_Overriding.
1948 (Covers): Handle properly designated types of anonymous access types,
1949 whose non-limited views are themselves incomplete types.
1950 (Add_Entry): Use an entity to store the abstract operation which hides
1952 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
1953 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
1954 initialization aggregate.

1958 they are labeled as potentially hidden by an abstract operator.
1959 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
1960 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
1961 (Write_Overloads): Output the abstract operator if present.
1962 (Add_Entry): Before inserting a new entry into the interpretation table
1963 for a node, determine whether the entry will be disabled by an abstract
1965 (Binary_Op_Interp_May_Be_Hidden): New routine.
1966 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
1968 (Function_Interp_May_Be_Hidden): New routine.
1969 (Has_Compatible_Type): Do not consider interpretations hidden by
1970 abstract operators when trying to determine whether two types are

1985 (Tagged_Kind): Handle private types.
1986 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
1987 output of implicit importation and exportation.
1988 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
1989 first formal of the thunk is always associated with the controlling
1990 type. In addition perform the following code cleanup: remove formal
1991 Thunk_Alias which is no longer required, cleanup evaluation of the
1992 the controlling type, and update the documentation.
1993 Replace occurrence of Default_Prim_Op_Count by

2017 * exp_util.ads, exp_util.adb:
2018 This patch replaces a number of occurrences of explicit tests for N_Null
2019 with calls to Known_Null. This improves tracking of null values, since
2020 Known_Null also catches null constants, and variables currently known to
2021 be null, so we get better tracking.
2022 (Ensure_Defined): create an itype reference only in the scope of the
2024 (Side_Effect_Free): A selected component of an access type that
2025 denotes a component with a rep clause must be treated as not

2027 value may be affected by a renaming.
2028 (Expand_Subtype_From_Expr): For limited objects initialized with build
2029 in place function calls, do nothing; otherwise we prematurely introduce
2030 an N_Reference node in the expression initializing the object, which
2031 breaks the circuitry that detects and adds the additional arguments to
2032 the called function. Bug found working in the new patch for statically
2033 allocated dispatch tables.
2034 (Is_Library_Level_Tagged_Type): New subprogram.
2035 (Remove_Side_Effects): If the expression of an elementary type is an

2038 attributes properly to compute the constraint on the resulting aggregate
2041 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
2042 class-wide type whose base type is an incomplete private type, leave
2043 class-wide type unfrozen so that freeze nodes can be generated
2044 properly at a later point.
2045 (Freeze_Entity, array case): Handle case of pragma Pack and component
2046 size attributre clause for same array.

2461 (__gnat_error_handler): Expect a third argument, ucontext_t *. Adjust it
2462 prior to raising as expected for any handler, before possible nested
2463 faults to make sure all the contexts in a chain have been adjusted by
2464 the time we propagate.

2563 won't be an associated Afile).
2564 (Elab_All_Links): Fail if a referenced unit cannot be found
2567 Fix comments in bindgen regarding consistency checks done in Bcheck:
2568 the checks are made across units within a partition, not across several
2570 Fix generation of C binder file for VxWorks.
2572 * lib.ads, lib.adb (Generic_Separately_Compiled): Rename to

2690 Thomas Quinot <quinot@adacore.com>
2692 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
2693 derived type with interface progenitors use the analyzed formal as the
2694 parent of the actual, to create renamings for all the inherited
2695 operations in Derive_Subprograms.
2696 (Collect_Previous_Instances): new procedure within of
2697 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
2698 unit being loaded, to ensure that the generation of global symbols is
2699 consistent in different compilation modes.
2700 (Is_Tagged_Ancestor): New function testing the ancestor relation that
2701 takes progenitor types into account.
2702 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
2703 traversing over the primitives of the formal and actual types to locate
2704 any abstract subprograms of the actual type that correspond to a
2705 nonabstract subprogram of the formal type's ancestor type(s), and issue
2706 an error if such is found.
2707 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
2708 Instantiate_Package_Body, Instantiate_Subprogram_Body):
2709 Remove bogus guard around calls to Inherit_Context.
2710 (Reset_Entity): If the entity is the selector of a selected component

2714 a predefined or internal unit.
2716 2007-08-14 Ed Schonberg <schonberg@adacore.com>

2719 parameter to determine whether operation applies to the prefix.
2720 (Complete_Object_Operation): If actual has an access type and
2721 controlling formal is not an in_parameter, reject the actual if it is
2722 an access_to_constant type.
2723 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
2724 type, the candidate operations are found in the scope of declaration of
2725 the type, because the type has no primitive subprograms.
2726 (Analyze_Selected_Component): If prefix is class-wide, and root type is
2727 a private extension, only examine visible components before trying to
2728 analyze as a prefixed call.
2729 Change Entity_List to Type_To_Use, for better readability.
2730 (Has_Fixed_Op): Use base type when checking whether the type of an
2731 operator has a user-defined multiplication/division
2732 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
2733 user-defined operators are available for fixed-point types.

2738 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
2739 formal At_Any_Place indicating, when True, that we want to test for
2740 availability of the stream attribute at any place (as opposed to the
2741 current visibility context only).
2742 (Missing_Read_Write_Attributes): A stream attribute is missing for the
2743 purpose of enforcing E.2.2(8) only if it is not available at any place.
2744 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
2745 when checking the legality of an extension aggregate in a preelaborable
2746 package. Treat the literal null as a valid default expression in a
2747 component declaration for a type with preelaborable initialization.
2748 A limited interface is a legal progenitor for the designated type of a
2749 remote access to class-wide type.

2762 (Find_Selected_Component, Has_Components): Handle properly non-limited
2763 views that are themselves incomplete types.
2764 Handle interfaces visible through limited-with clauses.
2765 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
2766 subprogram generic actual for which we have generated a renaming.
2767 Warn when the renaming introduces a homonym of
2768 the renamed entity, and the renamed entity is directly visible.

2774 appear in the subtree to the current allocator if it is not a static
2776 (Resolve_Allocator): Perform cleanup if resolution has determined that
2777 the allocator is not a coextension.
2778 (Resolve): Skip an interpretation hidden by an abstract operator only
2779 when the type of the interpretation matches that of the context.
2780 (Resolve): When looping through all possible interpretations of a node,
2781 do not consider those that are hidden by abstract operators.
2782 (Resolve_Actuals): When verifying that an access to class-wide object
2783 is an actual for a controlling formal, ignore anonymous access to
2784 subprograms whose return type is an access to class_wide type.
2785 (Resolve_Slice): If the prefix of the slice is a selected component
2786 whose type depends on discriminants, build its actual subtype before
2787 applying range checks on the bounds of the slice.
2788 (Valid_Conversion): In an instance or inlined body, compare root types,
2789 to prevent anomalies between private and public views.
2790 (Resolve): Improve error message for ambiguous fixed multiplication
2791 expressions that involve universal_fixed multiplying operations.

2808 extraneous layer of Any wrapping for member label.
2809 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
2810 elabration statements, register the package with the name server
2811 at the beginning, not at the end, of the elaboration statements so
2812 that they can create remote access to subprogram values that designate
2813 remote subprograms from the package.
2815 2007-08-14 Hristian Kirtchev <kirtchev@adacore.com>
2817 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
2818 values to compute the number of seconds since the Unix Epoc in order to
2819 account for Daylight Savings Time. Perform special processing for dates
2820 that are earlier than the Unix Epoc to obtain a negative number.

3905 System_Restrictions and initialization of the data unless there is
3906 some use of System.Restrictions in the partition.

3961 Arnaud Charlet <charlet@adacore.com>
3963 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
3964 applicable to types that have the With_Type flag set. Returns the
3965 non-limited view of the type, if available, otherwise the type itself.
3966 For class-wide types, there is no direct link in the tree, so we have
3967 to retrieve the class-wide type of the non-limited view of the Etype.
3968 New attributes Static_Initialization and Static_Elaboration_Desired.
3969 Remove the pragma Thread_Body, and the associated flag
3970 Is_Thread_Body in entities, and all related code.

3982 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
3983 (Original_Access_Type): Remove, not needed.
3984 (Root_Type): Handle properly subtypes of class-wide-types.
3987 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
3988 class-wide types visible through limited-with clauses.
3989 (Try_Primitive_Operation): When examining all primitive operations of a
3990 tagged type, do not consider subprograms labeled as hidden unless they
3991 belong to a private generic type with a tagged parent.
3992 (Try_Object_Operation): Extensive rewriting, to handle properly various
3993 overloading cases, when several ancestors may have class-wide operations
3994 that are possible candidates, and when the overloaded functions return
3995 array types and have defaulted parameters so that the call may be
3996 interpreted as an indexing.
3997 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
3998 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
3999 successive actuals before analyzing the call itself.
4000 (Try_Primitive_Operation): A primitive operation is compatible with the
4001 prefix if the prefix has a synchronized type and the type of the formal
4002 is its corresponding record, as can be the case when the primitive
4003 operation is declared outside of the body of the type.
4004 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
4005 perform homonym traversal, looking for class-wide operation matches
4006 (formerly done in statements of Try_Class_Wide_Operation). Matches on
4007 access parameters are now restricted to anonymous access types.
4008 (Mark_Allocator): An allocator with a discriminant association parent is
4010 (Try_One_Prefix_Interpretation): If the type of the object is
4011 incomplete, as can be happen when it is a limited view obtained through
4012 a limited_with_clause, the selected component is not part of a prefixed
4014 (Complete_Object_Operation): Diagnose properly an object that is not
4015 aliased when the corresponding controlling formal is an access
4017 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
4018 ambiguous calls in prefixed notation, where two primitives differ only
4019 in that the controlling argument of one is an access parameter.
4021 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
4022 whether a function that returns an unconstrained type can be inlined.
4023 (Process_Formals): Diagnose properly the illegal use of an incomplete
4024 type in the profile of an access_to_subprogram declaration.
4025 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
4026 operations are attached to the corresponding record.
4027 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
4028 When processing a primitive of a concurrent type which implements an
4029 interface change the type of all controlling formals to that of the
4030 corresponding record type.
4031 (Check_Synchronized_Overriding): Relax the conditional logic when trying
4032 to determine the tagged type to which a primitive belongs.
4033 (Check_Conventions): Capture condition to ignore a primitive operation
4034 (which is shared between the loop in Check_Conventions and the one in
4035 Check_Convention) in a new local function Skip_Check.
4036 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
4037 confusion with Check_Conventions' own Prim_Op local variable.
4038 (Create_Extra_Formals): Test for a tagged result type rather than a
4039 controlling result when determining whether to add a BIP_Alloc_Form
4040 formal and a BIP_Final_List formal to the function.
4041 (Check_Conformance); For parameters that are anonymous access types,
4042 subtype conformance requires that the not null and the constant
4043 indicators must match
4044 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
4045 to retrieve the appropriate type when processing a concurrent type
4046 declared within a generic. Minor comment reformatting. Change invocation
4047 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
4049 (Analyze_Subprogram_Body): If the return type of a function is an
4050 anonymous access to the limited view of a class-wide type, and the
4051 non-limited view of the type is available, update the type of the
4052 function so that code can be generated.
4053 (Process_Formals): In case of access-subtype itype whose designated
4054 type is also an itype (situation that happens now with access to
4055 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
4056 attribute to avoid backend problems.
4057 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
4058 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
4059 anonymous types' designated types are same before testing
4060 Subtypes_Statically_Match.
4061 (Create_Extra_Formals): Test for a named access parameter that is a
4062 controlling formal as an additional condition for adding an
4063 accessibility level formal. This can occur in the subp type created for
4064 dispatching calls in Expand_Dispatching_Call, and allows calling
4065 Create_Extra_Formals from that procedure rather than special-casing the
4066 extra formals there.
4067 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
4068 when the function has a controlling result.
4069 (Check_Returns): Add much more knowledge of the optimization of local
4070 raise statements to gotos, to retain proper warnings in this case.
4071 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
4072 nodes when looking for last statement.
4074 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
4075 class-wide types visible through limited with clauses.
4076 (Add_One_Interp): If the operands are anonymous access types, the
4077 predefined operator on universal_access is immediately visibles
4078 (Find_Unique_Type): Handle anonymous access to subprogram types just as
4079 other anonymous access types.
4080 (Disambiguate): Take into account CIL convention.
4081 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
4083 2007-06-06 Robert Dewar <dewar@adacore.com>

4088 Fix lower bound of tables.
4091 * nlists.adb: Ditto.
4092 (Prev_Node, Next_Node): Change index type to Int so that it properly
4093 covers the range First_Node_Id - 1 up.

4100 * exp_aggr.ads, exp_aggr.adb:
4101 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
4102 in extension aggregates.
4103 (Flatten): Other conditions being met, an aggregate is static if the
4104 low bound given by component associations is different from the low
4105 bound of the base index type.
4106 (Packed_Array_Aggregate_Handled): If the component type is itself a
4107 packed array or record, the front-end must expand into assignments.
4108 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
4109 Init_Pr, instead of Ancestor_Is_Expression.
4110 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
4111 coextension chain root, either generate a list controller or use the
4112 already existing one.
4113 (Static_Array_Aggregate): New procedure to construct a positional
4114 aggregate that can be handled by the backend, when all bounds and
4115 components are compile-time known constants.
4116 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
4117 types covering interface types into assignments.
4118 (Replace_Type): move to Build_Record_Aggr_Code.
4119 (Expand_Record_Aggr_Code): if the target of the aggregate is an
4120 interface type, convert to the definite type of the aggregate itself,
4121 so that needed components are visible.
4122 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
4123 components and the context is an extended return statement do not
4124 create a transient block for it, to prevent premature finalization
4125 before the return is executed.
4126 (Gen_Assign): Do not generate a call to deep adjust routine if the
4127 component type is itself an array of controlled (sub)-components
4128 initialized with an inner aggregate.
4129 (Component_Check): New name for Static_Check. This name is now more
4130 appropriate, and documentation is added which was missing.
4131 (Component_Check): Add test for bit aligned component value
4132 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
4133 Tagged_Comps, name is more appropriate given added function below.

4141 Terminated: Add unchecked type conversion from System.Address to
4142 System.Tasking.Task_Id when calling the predefined primitive
4144 Disable new Ada 05 accessibility check for JVM.NET targets, which
4145 cannot be implemented in a practical way.
4146 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
4147 the sources always references the tag of the actual object. Therefore,
4148 if 'Tag is applied in the sources to class-wide interface objects we
4149 generate code that displaces "this" to reference the base of the object.
4150 (Expand_N_Attribute_Reference, case Size): Return specified size if
4152 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
4153 has code that displaces the pointer of the object to manage interface
4154 types. However this code must not be executed when the prefix is a
4155 subprogram. This bug caused the wrong expansion of the internally
4156 generated assignment that fills the dispatch table when the primitive
4157 is a function returning a class-wide interface type.
4158 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
4159 Set_Attribute_Name for Name_Unaligned_Valid.

4165 If the initialization is the equivalent aggregate of the initialization
4166 procedure of the type, do not remove it.
4167 (Expand_N_Attribute_Definition_Clause): Exclude access variables
4168 initialized to null from having their expression reset to empty and
4169 note this exception in the comment.

4191 constrained subtype for a nominal unconstrained type, use its base type
4192 to check for conformance with the context.
4193 (Resolve_Attribute): Remove test of the access type being associated
4194 with a return statement from condition for performing accessibility
4195 checks on access attributes, since this case is now captured by
4196 Is_Local_Anonymous_Access.
4197 (Analyze_Access_Attribute): Set Address_Taken on entity
4198 (Analyze_Attribute, case Address): Set Address_Taken on entity
4199 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
4200 validating an access attribute whose prefix is a current instance.
4201 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
4202 applied to dispatching operations, if freezing is required then we set
4203 the attribute Has_Delayed_Freeze in the prefix's entity.
4204 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
4205 current scope if access of local subprogram taken
4206 (Analyze_Access_Attribute): Check legality of self-reference even if the
4207 expression comes from source, as when a single component association in
4208 an aggregate has a box association.
4209 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
4210 the prefix if it is a protected operation and the attribute is
4211 Unrestricted_Access.
4212 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
4213 reference to the base type of the context, to force a constraint check
4214 when the context is an access subtype with an explicit constraint.
4215 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
4216 node is rewritten as an interface conversion. leave unanalyzed after
4217 resolution, to ensure that type checking against the context will take

4221 Javier Miranda <miranda@adacore.com>
4222 Robert Dewar <dewar@adacore.com>
4224 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
4225 wrapper when the full view of the controlling type of an inherited
4226 function that dispatches on result implements interfaces.
4227 (Expand_N_Object_Declaration): In cases where the type of the
4228 declaration is anonymous access, create finalization list for it.
4229 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
4230 if the object has no explicit initialization, to match description of
4231 functionality of pragam Persistent_BSS.
4232 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
4233 new function to build static aggregates, to replace initialization call
4234 when static initialization is desired.
4235 (Freeze_Type): Generate a list controller for an access type whenever
4236 its designated type has controlled anonymous access discriminants.
4237 (Build_Equivalent_Aggregate): New procedure to compute a static
4238 aggregate to be used as default initialization for composite types,
4239 instead of a generating a call to the initialization procedure for the
4241 (Build_Initialization_Call): When available, replace a call to the
4242 initialization procedure with a copy of the equivalent static aggregate
4244 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
4245 declarations for objects of a class-wide interface type, rather than
4246 just identifiers, to prevent visibility problems.
4247 (Expand_N_Object_Declaration): When expanding the declaration for an
4248 object of a class-wide interface type, preserve the homonym chain of
4249 the original entity before exchanging it with that of the generated
4250 renaming declaration.
4251 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
4252 active, because there is no way to handle the exception.
4253 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
4254 to do a minimum decoration of the Access_Disp_Table list.
4255 (Expand_Record_Controller): Avoid the addition of the controller between
4256 the component containing the tag of a secondary dispatch table and its
4257 adjacent component that stores the offset to the base of the object.
4258 This latter component is only generated when the parent type has
4259 discriminants ---documented in Add_Interface_Tag_Components).
4260 (Apply_Array_Size_Check): Removed, no longer needed.
4261 (Expand_N_Full_Type_Declaration): If the type has anonymous access
4262 components, create a Master_Entity for it only if it contains tasks.
4263 (Build_Init_Procedure): Suppress the tag assignment compiling under
4265 (Freeze_Record_Type): Remove code associated with creation of dispatch
4267 (Init_Secondary_Tags): Update type of actuals when generating calls to

4271 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
4272 if Has_Init_Expression set.
4273 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
4274 Register_Primitive, which provides the same functionality.
4275 (Requires_Init_Proc): Return false in case of interface types.
4276 (Add_Secondary_Tables): Use the new attribute Related_Interface to
4278 (Predefined_Primitive_Freeze): Do not assume that an internal entity
4279 is always associated with a predefined primitive because the internal
4280 entities associated with interface types are not predefined primitives.
4281 Therefore, the call to Is_Internal is replaced by a call to the
4282 function Is_Predefined_Dispatching_Operation.
4283 (Make_Eq_If): When generating the list of comparisons for the
4284 components of a given variant, omit the controller component that is
4285 present if the variant has controlled components.
4287 2007-06-06 Javier Miranda <miranda@adacore.com>
4288 Hristian Kirtchev <kirtchev@adacore.com>
4289 Bob Duff <duff@adacore.com>
4291 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
4292 handle the creation of finalization lists and calls for nested
4293 coextensions when the root of the chains is part of a return statement.
4294 (Inside_A_Return_Statement): New function inside Complete_Coextension_
4296 (Expand_Record_Equality): Skip components that are interface types.
4297 (Displace_Allocator_Pointer): Add missing support for interface subtypes
4298 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
4299 with Rewrite_Coextension. Change the condition for detecting coextension
4301 (Is_Local_Access_Discriminant): Removed.
4302 (Rewrite_Coextension): New routine which rewrites a static coextension
4303 as a temporary and uses its unrestricted access in the construction of
4305 (Complete_Coextension_Finalization): New routine. Generate finalization
4306 attachment calls to all delayed coextensions.
4307 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
4308 the allocator is not a coextension itself and has delayed coextensions.
4309 If the current allocator is controlled, but also a coextension, delay
4310 the generation of the finalization attachment call.
4311 Rename local variable "Node" to "Nod" in order to avoid confusion with
4313 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
4314 limited types that are not inherently limited. Such an allocator is
4315 illegal, but is generated by the expander for a return statement, to
4316 copy the result onto the secondary stack. This is the only case where a
4317 limited object can be copied. Generate code to displace the pointer
4318 to the object if the qualified expression is a class-wide interface
4319 object. Such displacement was missing and hence the copy of the object
4321 (Apply_Accessibility_Check): Handle allocated objects initialized in
4323 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
4324 and Expand_Allocator_Expression. Allocating class-wide interface objects
4325 this routine displaces the pointer to the allocated object to reference
4326 the component referencing the corresponding secondary dispatch table.
4327 Expand_Allocator_Expression): Add missing support to allocate class-wide
4328 interface objects initialized with a qualified expression.
4329 (Get_Allocator_Final_List): Test for an anonymous access type that is a
4330 function result type, and use the finalization list associated with the
4331 function scope in that case (such an anonymous type should not be
4332 treated like an access parameter's type).
4334 2007-06-06 Ed Schonberg <schonberg@adacore.com>
4335 Gary Dismukes <dismukes@adacore.com>
4336 Javier Miranda <miranda@adacore.com>
4338 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
4339 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
4340 required exception handler.
4341 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
4342 properly the case of a function whose return type is a limited
4343 class-wide interface type. Modify the code of the accessibility
4344 check to handle class-wide interface objects. In this case we need to
4345 displace "this" to reference the primary dispatch table to get access
4346 to the TSD of the object (to evaluate its accessibility level).
4347 (Expand_N_Extended_Return_Statement): Test for a tagged result type
4348 rather than a controlling result as one of the conditions for
4349 generating tests of the implicit BIP_Alloc_Form formal. The
4350 initialization assignment is also handled according to whether the
4351 result is tagged instead of controlling.
4352 In the case where the init assignment is inserted in the "then" part of
4353 the allocation conditional, rewrite the target to be a dereference of
4354 the implicit BIP_Object_Access formal.
4355 If the returned value is unconstrained and created on the secondary
4356 stack, mark the enclosing block and function so that the secondary
4357 stack is not reclaimed on return.
4358 Treat returns from functions with controlling results similarly to
4359 returns from functions with unconstrained result subtypes.
4360 If the object returned is unconstrained, and an allocator must be
4361 created for it, analyze the allocator once the block for the extended
4362 return is installed, to ensure that finalizable components
4363 of the expression use the proper finalization list. Guard the call to
4364 Move_Final_List with a check that there is something to finalize.
4365 (Make_Tag_Ctrl_Assignment): Use "old" handling
4366 of controlled type assignment for virtual machines, since new code uses
4367 unsupported features (such as direct access to bytes in memory).
4369 2007-06-06 Gary Dismukes <dismukes@adacore.com>
4370 Ed Schonberg <schonberg@adacore.com>
4372 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
4373 accessibility actual, check for the case of an aliased object that has
4374 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
4375 we fall into processing for the attribute rather than the name of the
4377 (Expand_Inline_Call): If an actual is a literal, and the corresponding
4378 formal has its address taken in the body, create a temporary to capture
4379 value. If the return type is a limited interface, do not treat the
4380 return value as Controlled.
4381 (Is_In_Place_Function): If the return type is a limited interface,
4382 treat as returning in place. The actual returned object may not always
4383 be limited, but the caller has to assume that it is returned in place.
4384 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
4385 context of an allocator, use the correct finalization chain (that is,
4386 the chain belonging to the access type, rather than the chain belonging
4387 to the current scope).
4388 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
4389 result type rather than a controlling result as a precondition for
4390 adding an allocation form actual to a build-in-place call.
4391 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
4392 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
4393 primitive in the dispatch tables. This work is now done by Make_DT when
4395 (Register_Predefined_DT_Entry): Removed.
4396 (Add_Return): If end label is not present, use sloc of last statement
4397 for generated return statement in procedure, for better gdb behavior
4399 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
4400 object address nodes to ensure proper processing by routines like
4402 (Expand_Call): Fix generation of validity check for parameter
4403 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
4404 the allocation form parameter if the result subtype is constrained,
4405 except when the function has a controlling result.
4406 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
4407 rather than Is_Controlled and Has_Controlled_Component, since we want to
4408 include class-wide result types in this treatment. Also test for a
4409 controlling result, since that also requires passing a finalization
4411 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
4412 even when the result subtype is constrained, to handle calls involving
4413 controlling results.
4414 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
4415 is now called even when the result subtype is constrained, to handle
4416 calls involving controlling results.
4417 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
4418 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
4419 now performs the test).
4420 (Make_Build_In_Place_Call_In_Object_Declaration):
4421 Add_Alloc_Form_Actual_* is now called even when the result subtype is
4422 constrained, to handle calls involving controlling results.
4423 (Add_Return): Accomodate rewritten pattern from local raise to goto
4424 transformation, so that we still recognize an transfer statement
4425 and do the right thing here in that case.
4426 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
4427 and end of subprogram code.
4428 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
4429 support for primitives that are functions (without formals) with a
4431 (Inherited_From_Formal): If the actual subtype has not generic parent
4432 type, it is not an actual for a formal derived type, and there is no
4433 operation to inherit from the formal.
4435 2007-06-06 Ed Schonberg <schonberg@adacore.com>
4436 Thomas Quinot <quinot@adacore.com>
4438 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
4439 inserted cleanup code appropriately for GDB use.
4440 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
4441 exception handler for Deep_Adjust or Deep_Finalize.
4442 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
4443 Raise_From_Controlled_Operation is available, use a call to that
4444 subprogram instead of a plain "raise Program_Error" node to raise
4445 Program_Error if an exception is propagated from an Adjust or Finalize
4447 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
4448 appears in the optional statement list of a triggering alternative, the
4449 scope actions can be inserted directly there, and not in the list that
4450 includes the asynchronous select itself.
4452 2007-06-06 Ed Schonberg <schonberg@adacore.com>
4453 Robert Dewar <dewar@adacore.com>
4454 Hristian Kirtchev <kirtchev@adacore.com>
4456 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
4457 generated exception handler appropriately when debugging generated code.
4458 Deal properly with No_Exception_Propagation restriction mode.
4459 (Expand_N_Abort_Statement): Add an unchecked type conversion from
4460 System.Address to System.Tasking.Task_Id when processing the result of
4461 the predefined primitive _disp_get_task_id.
4462 (Expand_N_Asynchronous_Select): Clarify comment.
4463 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
4464 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
4465 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
4466 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
4467 privals and for generated call to Complete_Entry_Body, for better gdb
4469 (Copy_Result_Type): Utility to construct a parameter and result profile
4470 for protected functions whose return type is an anonymous access to
4472 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
4474 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
4475 point when the local-raise-to-goto transformation has taken place.
4477 2007-06-06 Javier Miranda <miranda@adacore.com>
4478 Nicolas Setton <setton@adacore.com>
4480 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
4481 functionality when the backend is generating code.
4482 Otherwise any serious error
4483 reported by the backend calling the frontend routine Error_Msg
4484 changes the Compilation_Mode to Check_Semantics, disables the
4485 functionality of this routine and causes the generation of
4486 spureous additional errors.
4488 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
4489 debugging information now generated by the compiler for fat-pointer
4491 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
4493 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.

4499 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
4500 For a remote call to a function with a classwide return type, apply an
4501 E.4(18) check to the returned value.
4502 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
4503 stream attributes of the designated type of an RACW, as they are not
4504 dispatching primitive operations.
4506 2007-06-06 Geert Bosch <bosch@adacore.com>
4508 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
4510 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
4512 (Do_Divide_Fixed_Universal): Handle case of negative Frac.

4517 2007-06-06 Javier Miranda <miranda@adacore.com>
4519 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
4520 attribute compiling package Ada.Tags under No_Run_Time_Mode.
4522 2007-06-06 Javier Miranda <miranda@adacore.com>
4524 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
4525 deallocation of class-wide interface objects.
4526 (Expand_Dispatching_Constructor_Call): Take into account that if the
4527 result of the dispatching constructor is an interface type, the
4528 function returns a class-wide interface type; otherwise the returned
4529 object would be actual. The frontend previously accepted returning
4530 interface types because Expand_Interface_Actuals silently performed
4531 the management of the returned type "as if" it were a class-wide
4533 (Expand_Dispatching_Constructor_Call): Replace call to
4534 Make_DT_Access_Action by direct call to Make_Function_Call.
4536 2007-06-06 Robert Dewar <dewar@adacore.com>
4537 Ed Schonberg <schonberg@adacore.com>
4539 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
4540 compute masking constant, since we now set Esize properly to the
4542 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
4543 to match the alignment.
4544 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
4545 packed arrays of 8 bits or less.
4547 * freeze.adb (Freeze_Entity): When freezing the formals of a
4548 subprogram, freeze the designated type of a parameter of an access type
4549 only if it is an access parameter.
4550 Increase size of C convention enumeration object
4551 (Freeze_Entity, array type case): Make sure Esize value is properly
4552 adjusted for the alignment if it is known.
4553 (Freeze_Entity, array type case): When checking bit packed arrays for
4554 the size being incorrect, check RM_Size, not Esize.
4555 (Freeze_Record_Type): Check for bad discriminated record convention
4556 (In_Exp_Body): Return true if the body is generated for a subprogram
4557 renaming, either an attribute renaming or a renaming as body.
4558 (Check_Itype): If the designated type of an anonymous access component
4559 is a non-protected subprogram type, indicate that it is frozen, to
4560 prevent out-of-scope freeze node at some subsequent call.
4561 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
4562 only if the subprogram is neither imported nor exported, as well as the
4563 NCA descriptor class if the subprogram is exported.

4570 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
4571 default initialization on an imported object, when there is no
4572 initialization call generated for it.

4583 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
4584 Pragma_CIL_Constructor): New names.
4586 * sem_cat.adb (Validate_Object_Declaration): An initialization that
4587 uses the equivalent aggregate of a type must be treated as an implicit
4589 (Get_Categorization): Check a unit for pragma Preelaborate only if it
4590 has none of the other categories.
4591 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
4592 to apply Import to an object renaming declaration.
4594 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
4595 from a C++ class should be declared as limited and that it will be
4596 considererd limited.
4597 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
4598 should be declared as limited and that it will be considererd limited.
4599 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
4600 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
4601 (Analyze_Pragma): Deal with Universal_Aliasing.
4602 (Sig_Flags): Likewise.
4603 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
4604 (Overflow_Checks_Unsuppressed): New flag.
4605 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
4606 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
4607 case of JVM or .NET targets, and compiling user code.
4608 Add debugging convenience routine rv

4615 absence of strange size or stream size clauses.
4616 (Build_Elementary_Write_Call): Same fix
4617 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
4618 set to value that does not match base type size.

4622 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
4623 object of a limited type can be initialized with a call to a function
4624 that returns in place. If the limited type has unknown discriminants,
4625 and the underlying type is a constrained composite type, build an actual
4626 subtype from the function call, as is done for private types.
4627 (Side_Effect_Free): An expression that is the renaming of an object or
4628 whose prefix is the renaming of a object, is not side-effect free
4629 because it may be assigned through the renaming and its value must be
4630 captured in a temporary.
4631 (Has_Controlled_Coextensions): New routine.
4632 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
4633 as is done for other limited types.

4641 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
4642 checksum if the main source could not be parsed.
4643 (Loat_Unit): When processing a child unit, determine properly whether
4644 the parent unit is a renaming when the parent is itself a child unit.
4645 Remove handling of with_type clauses.
4647 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

4658 2007-06-06 Vincent Celier <celier@adacore.com>
4659 Robert Dewar <dewar@adacore.com>
4661 * frontend.adb (Frontend): Return immediately if the main source could
4662 not be parsed, because of preprocessing errors.
4664 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.

4683 Add new warning for renaming of function return objects
4685 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
4686 (Tree_Read): Use size of object instead of type'object_size, since the
4687 latter is incorrect for packed array types.
4688 (Tree_Write): Same fix
4690 * opt.ads: Add new warning for renaming of function return objects
4691 (Generating_Code): New boolean variable used to indicate that the
4692 frontend as finished its work and has called the backend to process
4693 the tree and generate the object file.
4694 (GCC_Version): Is now private
4695 (Static_Dispatch_Tables): New constant declaration.

4701 (Warn_On_Unrepped_Components): New flag.
4703 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
4704 unit is a compilation unit, rather than relying on its scope, so that
4705 Standard can be renamed.
4706 (Analyze_Object_Renaming): Add new warning for renaming of function
4708 Also reject attempt to rename function return object in Ada 83 mode.
4709 (Attribute_Renaming): In case of tagged types, add the body of the
4710 generated function to the freezing actions of the type.
4711 (Find_Type): A protected type is visible right after the reserved word
4712 "is" is encountered in its type declaration. Set the entity and type
4713 rather than emitting an error message.
4714 (New_Scope): Properly propagate Discard_Names to inner scopes
4715 (Check_Nested_Access): New procedure.
4716 (Has_Nested_Access, Set_Has_Nested_Access): New procedures.

4728 Olivier Hainque <hainque@adacore.com>
4730 * g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
4731 absolute value of Header.Block_Size when displaying the freed physical
4733 (Allocate): Compute Storage_Address using Integer_Address, not
4734 Storage_Offset, because the range of Storage_Offset may not be large
4736 (Configure): New parameter Low_Level_Traces
4737 (Allocate, Deallocation, Free_Physically): Added low-level traces

6289 required for a conversion between two access-to-unconstrained-array
6291 (Expr_Known_Valid): Validity checks do not apply to discriminants, but
6292 to discriminant constraints on discriminant objects. This rule must
6293 apply as well to discriminants of protected types in private components.

6510 that use (a subtype of) the class-wide type of the enclosing type.

6513 Check_Anonymous_Access_Components rather than Empty.
6514 (Make_Incomplete_Type_Declaration): Add test for case where the type has
6515 a record extension in deciding whether to create a class-wide type,

6545 (Analyze_Subtype_Declaration): For an access subtype declaration, create
6546 an itype reference for the anonymous designated subtype, to prevent

6596 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
6597 when -gnatg is not specified.

6600 of synchronized interface types.
6601 (SIS_Entry_Active): Initialize global variable to False
6602 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

6626 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
6627 (Convert_Aggr_In_Allocator): If the allocator is for an access
6628 discriminant and the type is controlled. do not place on a finalization
6629 list at this point. The proper list will be determined from the
6631 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
6632 initialize record controller if needed, before the components, to ensure
6633 that they are properly finalized.
6634 (Build_Record_Aggr_Code): For the case of an array component that has a
6635 corresponding array aggregate in the record aggregate, perform sliding

6643 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
6645 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
6646 accessibility on class-wide allocators if the allocator occurs at the
6647 same scope level as the allocator's type. The check is guaranteed to
6648 succeed in that case, even when the expression originates from a
6649 parameter of the containing subprogram.
6650 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
6651 under No_Dispatching_Calls restriction. During the semantic analysis
6652 we already notified such violation.
6653 (Tagged_Membership): Constant folding. There is no need to check
6654 the tag at run-time if the type of the right operand is non
6655 class-wide abstract.

6667 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
6669 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
6670 initialize most the TSD components by means of an aggregate.
6671 Modify the declaration of the object containing the TSD
6672 because we now expand code that has a higher level of abstraction.
6673 The TSD has a discriminant containing the Inheritance Depth Level,
6674 value that is used in the membership test but also to fix the size
6675 of the table of ancestors.
6676 (Expand_Interface_Conversion): Insert function body at the closest place
6677 to the conversion expression, to prevent access-before-elaboration
6678 errors in the backend.

6703 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
6704 (Expand_Dispatching_Call): Replace generation of call to the run-time
6705 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
6706 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
6708 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
6709 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
6710 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and

6713 (Init_Predefined_Interface_Primitives): Replace generation of call to
6714 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
6717 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
6718 First (Parameter_Associations ()) with the call to First_Actual that
6719 returns an actual parameter expression for both named and positional
6722 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
6723 check violation of restriction No_Dispatching_Calls.
6724 (Check_Controlling_Type): A formal of a tagged incomplete type is a
6725 controlling argument.
6727 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
6728 First/Next_Component_Or_Discriminant
6729 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
6730 (Find_Implemented_Interface): Removed. All the calls to this subprogram

6732 provided by the function Has_Abstract_Interfaces.
6733 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
6734 support concurrent types implementing interfaces.
6735 (Find_Implemented_Interface): Removed. All the calls to this subprogram

6737 provided by the function Has_Abstract_Interfaces.
6738 (Remove_Side_Effects): replace Controlled_Type by
6739 CW_Or_Controlled_Type whenever the issue is related to
6740 using or not the secondary stack.
6742 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
6743 P_Interface_Type_Definition to fulfill the new interface (the formal
6744 Is_Synchronized is no longer required).
6746 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
6747 Update dependencies.
6749 * exp_atag.ads, exp_atag.adb: New file

6752 Bob Duff <duff@adacore.com>
6753 Cyrille Comar <comar@adacore.com>
6755 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
6756 anonymous, use finalization list of enclosing dynamic scope.
6757 (Expand_N_Package_Declaration): For a library package declaration
6758 without a corresponding body, generate RACW subprogram bodies in the
6759 spec (just as we do for the task activation call).
6760 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
6761 Is_Abstract_Type. Make sure these are called only when appropriate.
6762 Remove all code for DSP option
6763 (CW_Or_Controlled_Type): new subprogram.

6776 (Collect_Entry_Families): ...here. Call it to detect whether the family
6777 is potentially large.
6778 (Build_Entry_Count_Expression): If the family is potentially large, call
6779 Family_Size with 'Cap' set to true.
6780 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
6781 a protected version of an operation declared in the private part of
6782 a protected object, because they may be invoked through a callback.
6783 (Set_Privals): If the type of a private component is an anonymous access
6784 type, do not create a new itype for each protected body.
6785 If the body of a protected operation creates
6786 controlled types (including allocators for class-widetypes), the
6787 body of the corresponding protected subprogram must include a
6789 (Build_Activation_Chain_Entity): Build the chain entity for extended
6791 (Type_Conformant_Parameters): Use common predicate Conforming_Types
6792 to determine whether operation overrides an inherited primitive.

6806 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
6807 E_Constant, depending upon Variable formal.
6808 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
6809 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
6810 parameter that requires an extra constrained parameter, declare
6811 temporary for actual as a variable, not a constant.
6812 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
6813 the unit being compiled is the one that contains the stub type.
6814 Change primitive operation name for the RACW associated with a RAS
6815 from Call to _Call so it cannot clash with any legal identifier.

6818 (Append_RACW_Bodies): New subprogram.
6819 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to

6822 statements in the HSS at the end of the pacakge.
6823 When expanding a package spec, this list correspond to the
6825 (Add_Receiving_Stubs_To_Declarations): Append the function
6826 registering the receiving stubs at the end of the 'Stmts' list.
6827 (RCI_Package_Locator): Pass the new Version generic formal when
6828 instantiating a RCI_Locator package.
6829 (Build_From_Any_Function): To compute the High bound for an
6830 unconstrained array actual, we add the Low bound with the length.
6831 Thus we must convert the low bound and the length to an appropriate
6832 type before doing the sum.
6833 (Build_Subprogram_Receiving_Stubs, PolyORB):
6834 * Retrieve the extra formals parameters at the
6835 end of the parameter stream.
6836 * Use Move_Any_Value to write back out parameters
6837 after executing the request as it is more efficient
6838 than Copy_Any_Value.
6839 * Build the any containing Extra Formals with the
6840 appropriate typecode.
6841 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
6842 empty Component_List.
6843 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
6844 the tree the declaration for an object that serves as actual parameter
6845 in server-side stubs.

6855 function with the first not implicit parent type.
6856 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
6857 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
6858 typecode from the Etype. Therefore we retrieve the correct typecode
6859 with a call to Get_Any_Type.
6860 (Copy_Specification): Do controlling formal type substitution based on
6861 Is_Controlling_Formal flag, instead of caller-provided object type.
6862 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
6863 a RACW primitive operation, we might get a subprogram declaration for an
6864 ancestor of the RACW designated type (not for the designated type
6865 itself), in the case where this operation is inherited. In this case we
6866 have no easy means of determining the original tagged type for which
6867 the primitive was declared, so instead we now rely on
6868 Copy_Specification to use the Is_Controlling_Formal flag to determine
6869 which formals require type substitution.

6877 handler unsuitable as a target for a local raise statement.
6878 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
6879 run-time subprogram CW_Membership by call to Build_CW_Membership.
6880 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
6881 by a function call, a temporary must be created before expanding the
6882 Constructor_Call itself, to prevent out-of-order elaboration in the
6883 back-end when stack checking is enabled..
6885 2007-04-06 Ed Schonberg <schonberg@adacore.com>
6887 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
6888 result are the bounds of the left operand, not the right.

7011 standard 8bits encoding.
7012 (WS2SU): As above but converting from wide-sring to string.
7013 This is needed as it is necessary to have access to both versions in the
7014 runtime for the form parameter encoding support.
7015 This set of patch add support for the encoding form parameter.
7016 (S2WS): Improve implementation to handle cases where the filename is not
7017 UTF-8 encoded. In this case we default to using the current code page
7020 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration

7065 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
7066 __gnat_adjust_context_for_raise.
7067 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
7068 implementation of floating point operations as native x86 targets.
7069 So the FPU should be initialized in the same way using finit. Fix
7070 floating point operations accuracy issues.

7141 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
7142 it no longer destroys the contents of Name_Buffer or Name_Len and
7143 non-standard and invalid names are handled better.
7144 (Get_Decoded_Name_String): Improve performance by using
7145 Name_Has_No_Encodings flag in the name table.

7158 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
7159 illegal in Ada 95, in cases where it is legal. Change the warnings to
7160 errors in other cases. Don't give the error unless the "not null"
7161 parses properly. Correct the source position at which the error occurs.
7162 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
7163 P_Null_Exclusion, to suppress "not null" warnings.

7294 full word is no longer compared twice.
7296 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7298 * sem_ch10.adb (Install_Limited_Context_Clauses.
7299 Expand_Limited_With_Clause): Use a new copy of selector name in the
7300 call to Make_With_Clause. This fixes the tree structure for ASIS
7301 purposes. Nothing is changed in the compiler behaviour.
7302 (Process_Body_Clauses): Handle properly use clauses whose prefix is
7304 (Install_Limited_With_Clauses): Do not install non-limited view when it
7305 is still incomplete.
7307 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7308 Gary Dismukes <dismukes@adacore.com>
7310 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
7311 when capturing size information, instead of base type, which for a
7312 formal array type will be the unconstrained type.
7313 (Analyze_Formal_Object_Declaration): Add check for illegal default
7314 expressions for a formal in object of a limited type.
7315 (Instantiate_Object): Ditto.
7316 (Check_Formal_Package_Instance): Skip entities that are formal objects,
7317 because they were defaulted in the formal package and no check applies
7319 (Check_Formal_Package_Instance): Extend conformance check to other
7320 discrete types beyond Integer.
7321 (Process_Default): Copy directly the unmatched formal. A generic copy
7322 has already been performed in Analyze_Formal_Package.
7323 (Analyze_Associations): If a formal subprogram has no match, check for
7324 partial parametrization before looking for a default, to prevent
7326 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
7327 not set the instantiation environment before analyzing the actuals.
7328 Fixes regression on 8515-003 with implementation of AI-133.
7329 Set_Instance_Env checks whether the generic unit is a predefined
7330 unit, in which case the instance must be analyzed with the latest Ada
7331 mode. This setting must take place after analysis of the actuals,
7332 because the actuals must be analyzed and frozen in the Ada mode extant
7333 outside of the current instantiation.
7334 (Save_Env, Restore_Env): Preserve and restore the configuration
7335 parameters so that predefined units can be compiled in the proper Ada
7337 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
7338 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
7339 and Is_Abstract_Type.
7340 (Analyze_Formal_Package): For better error recovery, Add exception
7341 handler to catch Instantion_Error, which can be raised in
7342 Analyze_Associations

7345 Bob Duff <duff@adacore.com>
7346 Gary Dismukes <dismukes@adacore.com>
7348 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
7349 prefix type is a discriminated subtype of the type of the formal.
7350 (Analyze_Allocator): Collect all coextensions regardless of the context.
7351 Whether they can be allocated statically is determined in exp_ch4.
7352 (Analyze_Selected_Component): If the prefix is a limited view and the
7353 non-limited view is available, use the non-limited one.
7354 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
7355 therefore illegal), suggest a qualified expression rather than a type
7356 conversion, because a type conversion would be illegal in this context.
7357 (Anayze_Allocator): Trace recursively all nested allocators so that all
7358 coextensions are on the corresponding list for the root. Do no mark
7359 coextensions if the root allocator is within a declaration for a stack-
7360 allocated object, because the access discriminants will be allocated on
7362 (Analyze_Call): Remove restriction on calls to limited functions for the
7363 cases of generic actuals for formal objects, defaults for formal objects
7364 and defaults for record components.
7365 (Analyze_Allocator): Before analysis, chain coextensions on the proper
7366 element list. Their expansion is delayed until the enclosing allocator
7367 is processed and its finalization list constructed.
7368 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
7369 for an operation with the given name among the primitive operations of
7370 the corresponding record type.
7371 (Analyze_Selected_Component): If the prefix is a task type that
7372 implements an interface, and there is no entry with the given name,
7373 check whether there is another primitive operation (e.g. a function)
7375 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
7376 properly the indexing of a function call written in prefix form, where
7377 the function returns an array type, and all parameters of the function
7378 except the first have defaults.
7379 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
7380 the original operands, rather than relocating them, for efficiency and
7381 to work properly when an operand is overloaded.
7382 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
7383 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
7384 (Analyze_Selected_Component): If the prefix is a private extension, only
7385 scan the visible components, not those of the full view.
7386 (Try_Primitive_Operation): If the operation is a procedure, collect all
7387 possible interpretations, as for a function, because in the presence of
7388 classwide parameters several primitive operations of the type can match
7389 the given arguments.
7391 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7392 Robert Dewar <dewar@adacore.com>
7394 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a

7400 Thomas Quinot <quinot@adacore.com>
7402 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
7403 out of Analyze_Package_Declaration, because processing must be applied
7404 to package bodies as well, for deferred constants completed by pragmas.
7405 (Analyze_Package_Declaration): When the package declaration being
7406 analyzed does not require an explicit body, call Check_Completion.
7407 (May_Need_Implicit_Body): An implicit body is required when a package
7408 spec contains the declaration of a remote access-to-classwide type.
7409 (Analyze_Package_Body): If the package contains RACWs, append the
7410 pending subprogram bodies generated by exp_dist at the end of the body.
7411 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
7412 Is_Abstract_Subprogram and Is_Abstract_Type.
7413 (Preserve_Full_Attributes): The full entity list is not an attribute
7414 that must be preserved from full to partial view.
7416 * sem_dist.adb (Add_RAS_Dereference_TSS):
7417 Change primitive name to _Call so it cannot clash with any legal
7418 identifier, and be special-cased in Check_Completion.
7419 Mark the full view of the designated type for the RACW associated with
7420 a RAS as Comes_From_Source to get proper view switching when installing
7421 private declarations.
7422 Provite a placeholder nested package body along with the nested spec
7423 to have a place for Append_RACW_Bodies to generate the calling stubs
7424 and stream attributes.
7426 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7427 Robert Dewar <dewar@adacore.com>
7429 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
7430 that is a limited view, check the non-limited view if available.
7431 (Undefined): Refine error message for missing with of Text_IO
7432 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
7433 to distinguish real missing with cases.
7434 Fix format of all missing with messages
7435 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
7436 renaming as body when renamed entity is abstract.
7438 2007-04-06 Ed Schonberg <schonberg@adacore.com>
7439 Javier Miranda <miranda@adacore.com>
7441 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
7442 predicate recursive, to handle complex expressions on literals whose
7443 spurious ambiguity comes from the abstract interpretation of some
7445 (Interface_Present_In_Ancestor): Add support to concurrent record
7447 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
7448 Is_Abstract_Subprogram and Is_Abstract_Type.

7451 Javier Miranda <miranda@adacore.com>
7453 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
7454 dereference of a local object R created as a reference to another
7455 object O, use the access level of O.
7456 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
7457 rather than local Same_Formal_Type, to check whether protected operation
7458 overrides an inherited one.
7459 (Same_Formal_Type): New predicate, used when matching signatures of
7460 overriding synchronized operations, to handle the case when a formal
7461 has a type that is a generic actual.
7462 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
7463 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
7464 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
7465 syntactic ambiguities involving indexing of function calls that return
7467 (Abstract_Interface_List): New subprogram that returns the list of
7468 abstract interfaces associated with a concurrent type or a
7469 concurrent record type.
7470 (Interface_Present_In_Parent): New subprogram used to check if a
7471 given type or some of its parents implement a given interface.
7472 (Collect_Abstract_Interfaces): Add support for concurrent types
7473 with interface types.
7474 (Has_Abstract_Interfaces): Add support for concurrent types with
7476 (Is_Parent): New subprogram that determines whether E1 is a parent
7477 of E2. For a concurrent type its parent is the first element of its
7478 list of interface types; for other types this function provides the
7479 same result than Is_Ancestor.
7480 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
7481 (Collect_Synchronized_Interfaces): Removed because the subprogram
7482 Collect_Abstract_Interfaces provides this functionality.
7483 (Collect_Abstract_Interfaces): Minor update to give support to
7484 concurrent types and thus avoid undesired code duplication.
7485 (Get_Subprogram_Entity): Handle entry calls.
7486 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
7488 (Enter_Name): Do not give -gnatwh hiding warning for record component
7489 entities, they never result in hiding.

7499 (Local_Raise_Statements): New field in N_Exception_Handler_Node
7500 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

7504 can be an E_Return_Statement.
7505 (Is_Coextension): New flag for allocators.

7514 before propagating exception.
7516 2007-04-06 Olivier Hainque <hainque@adacore.com>
7518 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
7519 an address always within the call instruction from a return address.
7521 2007-04-06 Olivier Hainque <hainque@adacore.com>
7522 Eric Botcazou <botcazou@adacore.com>
7524 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
7525 expression with a COMPOUND_EXPR including the call instead of emitting
7526 the call directly here.
7527 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
7528 high bound is constant and the slice is empty. Tidy.
7529 (tree_transform, case N_Op_Not): Handle properly the case where the
7530 operation applies to a private type whose full view is a modular type.
7531 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
7532 Address_Clause, use the associated Expression as the GNAT tree
7533 representing the choice value to ensure the corresponding GCC tree is
7535 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
7536 instead of just the operands, as the base GCC stabilize_reference does.
7537 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
7538 requested; otherwise fail.
7539 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
7541 2007-04-06 Thomas Quinot <quinot@adacore.com>

7544 implementation of UI_Div.
7545 (UI_Div): Reimplement as a call to UI_Div_Rem.
7546 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
7547 remainder, avoiding the cost of a multiplication and a subtraction.
7548 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
7549 provides both quotient and remainder in a single computation.
7550 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
7552 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
7553 is undefined if the given n is not inversible.

7570 (builtin_decls): New global, vector of available builtin functions.
7571 (gnat_pushdecl): Add global builtin function declaration nodes to the

7819 anonymous access types.
7820 (Valid_Conversion): For a conversion to a numeric type occurring in an

8524 Ed Schonberg <schonberg@adacore.com>
8526 * exp_aggr.adb (Build_Record_Aggr_Code): For extension aggregates, if
8527 the parent part is a build-in-place function call, generate assignments.
8528 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
8529 are build-in-place function calls.
8530 (Replace_Self_Reference): New subsidiary of
8531 Make_OK_Assignment_Statement, to replace an access attribute that is a
8532 self-reference into an access to the appropriate component of the
8533 target object. Generalizes previous mechanism to handle self-references
8534 nested at any level.
8535 (Is_Self_Referential_Init): Remove, not needed.
8536 (Is_Self_Referential_Init): New predicate to simplify handling of self
8537 referential components in record aggregates.
8538 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
8539 check for presence of entity before checking for self-reference.
8540 (Has_Default_Init_Comps): Return True if a component association is a
8541 self-reference to the enclosing type, which can only come from a
8542 default initialization.
8543 (Make_OK_Assignment_Statement): If the expression is of the form
8544 Typ'Acc, where Acc is an access attribute, the expression comes from a
8545 default initialized self-referential component.
8546 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
8547 that has been derived from several abstract interfaces we must also
8548 initialize the tags of the secondary dispatch tables.

8551 Thomas Quinot <quinot@adacore.com>
8552 Javier Miranda <miranda@adacore.com>
8553 Robert Dewar <dewar@adacore.com>
8556 (Expand_Access_To_Protected_Op): If the context indicates that an access
8557 to a local operation may be transfered outside of the object, create an
8558 access to the wrapper operation that must be used in an external call.
8559 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
8560 target, pass the Valid attribute applied to a floating-point prefix on
8561 to the back end without expansion.
8562 (Storage_Size): Use the new run-time function Storage_Size to retrieve
8563 the allocated storage when it is specified by a per-object expression.
8564 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
8565 Nothing to do here, the attribute has been rewritten during semantic
8567 (Expand_Attribute_Reference): Handle expansion of the new Priority
8569 (Find_Fat_Info): Handle case of universal real
8570 (Expand_Access_To_Protected_Op): Fix use of access to protected
8571 subprogram from inside the body of a protected entry.
8572 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
8573 'Access and 'Unrestricted_Access, to transform the attribute reference
8575 (Is_Constrained_Aliased_View): New predicate to help determine whether a
8576 subcomponent's enclosing variable is aliased with a constrained subtype.
8577 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
8578 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
8579 an aliased prefix must be known to be constrained in order to use True
8580 for the attribute value, and now it's possible for some aliased views
8581 to be unconstrained.
8583 2006-10-31 Robert Dewar <dewar@adacore.com>
8585 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
8586 (Expand_Entity_Reference): Correct error of not handling subprogram
8587 formals in current_value processing.

8594 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
8595 register in the final list objects containing class-wide interfaces;
8596 otherwise we incorrectly register the tag of the interface in the final
8598 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
8599 generate the wrapper if the parent primitive is abstract. This is
8600 required to report the correct error message.
8601 (Expand_N_Subtype_Indication): Do validity checks on range
8602 (Clean_Task_Names): If an initialization procedure includes a call to
8603 initialize a task (sub)component, indicate that the procedure will use
8604 the secondary stack.
8605 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
8606 compatibility for interfacing with CPP by default.
8607 (Expand_N_Object_Declaration): Only build an Adjust call when the
8608 object's type is a nonlimited controlled type.
8609 * exp_ch3.adb: Add with and use of Exp_Ch6.
8610 (Expand_N_Object_Declaration): Check for object initialization that is a
8611 call to build-in-place function and apply Make_Build_In_Place_Call_In_
8612 Object_Declaration to the call.
8613 (Freeze_Type): When the designated type of an RACW was not frozen at the
8614 point where the RACW was declared, validate the primitive operations
8615 with respect to E.2.2(14) when it finally is frozen.
8616 (Build_Initialization_Call,Expand_Record_Controller): Rename
8617 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
8618 return-by-reference has no meaning in Ada 2005.
8619 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
8620 to register tag of the immediate ancestor interfaces in the
8622 (Init_Secondary_Tags): Moved to the specification to allow the
8623 initialization of extension aggregates with abstract interfaces.
8624 (Build_Master_Renaming): Make public, for use by function declarations
8625 whose return type is an anonymous access type.
8626 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
8627 Insert_List_Before_And_Analyze after the generation of the specs
8628 associated with null procedures.
8629 (Expand_Tagged_Root): Update documentation in its specification.
8630 (Init_Secondary_Tags): Update documentation.
8631 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
8632 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
8633 then generate code to inherit the contents of the dispatch table
8634 directly from the ancestor.
8635 (Expand_Record_Controller): Insert controller component after tags of
8636 implemented interfaces.
8637 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
8638 create null procedure overridings when null procedures are inherited
8640 (Make_Null_Procedure_Specs): New procedure to generate null procedure
8641 declarations for overriding null primitives inherited from interfaces.
8642 (Is_Null_Interface_Procedure): New function in
8643 Make_Null_Procedure_Specs.
8644 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
8645 immediate ancestor of a tagged type is an abstract interface type we
8646 must generate the specification of the predefined primitives associated
8647 with controlled types (because the dispatch table of the ancestor is
8648 null and hence these entries cannot be inherited). This is required to
8649 elaborate well the dispatch table.

8657 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
8659 (Expand_N_In): Do validity checks on range
8660 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
8661 (Expand_N_Allocator): For "new T", if the object is constrained by
8662 discriminant defaults, allocate the right amount of memory, rather than
8663 the maximum for type T.
8664 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
8665 when the allocator is initialized by a build-in-place call, since the
8666 allocator is already rewritten as a reference to the function result,
8667 and this prevents an unwanted duplication of the function call.
8668 Add with and use of Exp_Ch6.
8669 (Expand_Allocator_Expresssion): Check for an allocator whose expression
8670 is a call to build-in-place function and apply
8671 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
8672 untagged designated types).
8673 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
8674 optimization if source or target is biased.
8675 (Expand_N_Allocator): Add comments for case of an allocator within a
8676 function that returns an anonymous access type designating tasks.
8677 (Expand_N_Allocator): apply discriminant checks for access
8678 discriminants of anonymous access types (AI-402, AI-416)

8685 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
8687 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
8688 (Expand_N_Assignment_Statement): Call
8689 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
8690 build-in-place function call. Currently, this can happen only for
8691 assignments that come from aggregates.
8692 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
8693 in order to alleviate the upward compatibility introduced by AI-318.
8694 (Expand_N_Extended_Return_Statement): Add support for handling the
8695 return object as a build-in-place result.
8696 (Expand_Non_Function_Return): Implement simple return statements nested
8697 within an extended return.
8698 (Enable_New_Return_Processing): Turn on the new processing of return
8700 (Expand_Non_Function_Return): For a return within an extended return,
8701 don't raise Program_Error, because Sem_Ch6 now gives a warning.
8702 (Expand_N_Extended_Return_Statement): Implement AI-318
8703 (Expand_Simple_Function_Return): Ditto.
8704 (Expand_N_If_Statement): Handle new -gnatwt warning
8705 (Expand_N_Case_Statement): Handle new -gnatwt warning
8706 (Expand_N_Assignment): Handle assignment to the Priority attribute of
8708 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
8709 validity checking of assignments to elementary record components.
8710 (Expand_N_Return_Statement): return Class Wide types on the secondary
8711 stack independantly of their controlled status since with HIE runtimes,
8712 class wide types are not potentially controlled anymore.
8714 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
8717 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
8718 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
8719 it expects a block, procedure, or task. The return statement will get
8720 turned into a block, and Expand_Cleanup_Actions will happen then.
8722 2006-10-31 Robert Dewar <dewar@adacore.com>
8723 Ed Schonberg <schonberg@adacore.com>
8724 Bob Duff <duff@adacore.com>
8725 Gary Dismukes <dismukes@adacore.com>
8727 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
8729 (Expand_Inlined_Call): Tagged types are by-reference types, and
8730 therefore should be replaced by a renaming declaration in the expanded
8731 body, as is done for limited types.
8732 (Expand_Call): If this is a call to a function with dispatching access
8733 result, propagate tag from context.
8734 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
8736 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
8737 build-in-place when the right-hand side of an assignment is a
8738 build-in-place function call.
8739 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
8740 of the explicit dereference of the allocator to the result subtype of
8741 the build-in-place function. This is needed to satisfy type checking
8742 in cases where the caller's return object is created by an allocator for
8743 a class-wide access type and the type named in the allocator is a
8745 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
8746 conversion of the reference to the declared object to the result subtype
8747 of the build-in-place function. This is needed to satisfy type checking
8748 in cases where the declared object has a class-wide type. Also, in the
8749 class-wide case, change the type of the object entity to the specific
8750 result subtype of the function, to avoid passing a class-wide object
8751 without explicit initialization to the back end.
8752 (Register_Interface_DT_Entry): Moved outside the body of
8753 Freeze_Subprogram because this routine is now public; it is called from
8754 Check_Dispatching_Overriding to handle late overriding of abstract
8755 interface primitives.
8756 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
8757 adding an implicit access actual on a call to a build-in-place function.
8758 (Expand_Actuals): Test for an actual parameter that is a call to a
8759 build-in-place function and apply
8760 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
8761 (Is_Build_In_Place_Function): New function to determine whether an
8762 entity is a function whose calls should be handled as build-in-place.
8763 (Is_Build_In_Place_Function_Call): New function to determine whether an
8764 expression is a function call that should handled as build-in-place.
8765 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
8766 calls to build-in-place functions as the initialization of an allocator.
8767 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
8768 handling calls to build-in-place functions in contexts that do not
8769 involve init of a separate object (for example, actuals of subprogram
8771 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
8772 handling calls to build-in-place functions as the initialization of an
8774 (Detect_Infinite_Recursion): Add explicit parameter Process to
8775 instantiation of Traverse_Body to avoid unreferenced warning.
8776 (Check_Overriding_Inherited_Interfaces): Removed.
8777 (Register_Interface_DT_Entry): Code cleanup.
8778 (Register_Predefined_DT_Entry): Code cleanup.
8779 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
8780 inlined statements if within a transient scope.
8781 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
8782 formal parameters with occurrences of actuals in inlined body, establish
8783 visibility on the proper view of the actual's subtype for the body's
8785 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
8786 compatibility mode and we have an imported CPP subprogram because
8787 for now we assume that imported CPP primitives correspond with
8788 objects whose constructor is in the CPP side (and therefore we
8789 don't need to generate code to register them in the dispatch table).
8790 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
8791 aligned selected component.
8792 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
8793 the actual of an in-mode parameter is a type conversion.
8794 (Expand_Actuals): If the call does not come from source and the actual
8795 is potentially misaligned, let gigi handle it rather than rejecting the
8796 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
8797 Class Wide types as returning by reference independantly of their
8798 controlled status since with HIE runtimes class wide types are not
8799 potentially controlled anymore.
8801 2006-10-31 Ed Schonberg <schonberg@adacore.com>
8803 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
8804 references that are private components of the protected object.
8805 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
8806 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
8807 instantiation to deal with warnings.
8808 (Initialize_Protection): If expression for priority is non-static, use
8809 System_Priority as its expected type, in case the expression has not

8814 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
8815 initialization of Homonym_Len.
8816 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
8817 names from fully qualified name. Fixes problem of duplicate
8818 external names differing only in the presence of such a block name.
8820 2006-10-31 Thomas Quinot <quinot@adacore.com>
8821 Pablo Oliveira <oliveira@adacore.com>
8823 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
8824 subprogram Ids, even if they are not yet assigned.
8825 (Build_Subprogram_Id): It is now this function that will take care of
8826 calling Assign_Subprogram_Ids if necessary.
8827 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
8828 should be done only once they are assigned.
8829 (Build_From_Any_Function, case of tagged types): Add missing call to
8831 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
8832 type for an RACW type.
8833 (Add_RACW_Features): When processing an RACW declaration for which the
8834 designated type is already frozen, enforce E.2.2(14) rules immediately.
8835 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
8836 special reordering of controlling formals.
8838 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
8839 associated stub type for an RACW type.
8841 2006-10-31 Ed Schonberg <schonberg@adacore.com>
8843 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
8844 fixed-point operations in an integer context, i.e. as operands of a
8845 conversion to an integer type, indicate that result must be rounded.
8847 2006-10-31 Robert Dewar <dewar@adacore.com>
8849 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
8850 cases, pass the encoding method, since it is now required by the run
8853 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
8854 assumption that Str'First = 1.
8855 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
8856 it on to the Value_Wide_Wide_Character call.
8857 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
8858 properly handles a string of the form quote-encoded_wide_char-quote.
8860 * s-wchcnv.adb: Minor reformatting
8862 2006-10-31 Javier Miranda <miranda@adacore.com>
8864 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
8865 run-time membership test to ensure that the constructed object
8866 implements the target abstract interface.
8868 2006-10-31 Robert Dewar <dewar@adacore.com>
8870 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
8871 Machine_Attribute pragma internally to implement the user pragma.
8872 Add processing for pragma Interface so that it is now completely
8873 equivalent to pragma Import.
8875 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
8876 so that it can be applied to all entities, including record components
8877 and enumeration literals.
8878 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
8879 priority ranges are correct, verify compatibility against task
8880 dispatching and locking policies, and if everything is correct an entry
8881 is added to the table containing priority specific dispatching entries
8882 for this compilation unit.
8883 (Delay_Config_Pragma_Analyze): Delay processing
8884 Priority_Specific_Dispatching pragmas because when processing the
8885 pragma we need to access run-time data, such as the range of
8886 System.Any_Priority.
8887 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
8888 Allow pragma Unreferenced as a context item
8889 Add pragma Preelaborable_Initialization
8890 (Analyze_Pragma, case Interface): Interface is extended so that it is
8891 now syntactically and semantically equivalent to Import.
8892 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
8893 insertion characters.
8894 Add handling for Pragma_Wide_Character_Encoding
8895 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
8896 never supercedes a real restriction, and that a real restriction
8897 always supercedes a warning.

8905 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
8906 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
8907 Is_Inherently_Limited_Type, because return-by-reference has no meaning
8909 (Find_Node_To_Be_Wrapped): Use new method of determining the result
8910 type of the function containing a return statement, because the
8911 Return_Type field was removed. We now use the Return_Applies_To field.
8913 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
8914 (Build_Task_Image_Decl): If procedure is not called from an
8915 initialization procedure, indicate that function that builds task name
8916 uses the sec. stack. Otherwise the enclosing initialization procedure
8917 will carry the indication.
8918 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
8919 N_Object_Declaration instead.
8920 (Kill_Dead_Code): New interface to implement -gnatwt warning for
8921 conditional dead code killed, and change implementation accordingly.
8922 (Insert_Actions): Add N_Return_Object_Declaration case.

8929 (Set_Current_Value_Condition): Corresponding changes
8930 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
8931 (Get_Current_Value_Condition): Handle simple boolean operands
8932 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
8933 (Get_Current_Value_Condition): If the variable reference is within an
8934 if-statement, does not appear in the list of then_statments, and does
8935 not come from source, treat it as being at unknown location.
8936 (Get_Current_Value_Condition): Enhance to allow while statements to be
8937 processed as well as if statements.
8938 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not

8965 (Generate_Reference): Centralize handling of pragma Obsolescent here
8966 (Generate_Reference): Accept an implicit reference generated for a
8967 default in an instance.
8968 (Generate_Reference): Accept a reference for a node that is not in the
8969 main unit, if it is the generic body corresponding to an subprogram
8972 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
8974 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
8976 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
8978 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
8979 use clauses, to avoid messages on packages used to qualify, and also
8980 to avoid messages from obsolescent units.
8981 (Warn_On_Useless_Assignments): Don't generate messages for imported
8982 and exported variables.
8983 (Warn_On_Useless_Assignments): New procedure
8984 (Output_Obsolescent_Entity_Warnings): New procedure
8985 (Check_Code_Statement): New procedure

8991 2006-10-31 Olivier Hainque <hainque@adacore.com>
8993 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
8994 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.

8997 Robert Dewar <dewar@adacore.com>
8998 Ed Schonberg <schonberg@adacore.com>
9000 * g-awk.adb (Default_Session, Current_Session): Compile this file in
9001 Ada 95 mode, because it violates the new rules for AI-318.
9003 * g-awk.ads: Use overloaded subprograms in every case where we used to
9004 have a default of Current_Session. This makes the code closer to be
9005 correct for both Ada 95 and 2005.
9007 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
9008 code, relying on the fact that the compiler generates a warning
9009 instead of an error in -gnatg mode.
9011 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
9012 E_Return_Statement entity kind.
9013 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
9015 * par.adb (P_Interface_Type_Definition): Addition of one formal to
9016 report an error if the reserved word abstract has been previously found.
9017 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
9019 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
9020 parenthesized range attribute usage
9021 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
9023 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
9024 in the syntax for extended_return_statement. This is not in the latest
9025 RM, but the ARG is expected to issue an AI allowing this.
9026 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
9027 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
9028 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
9029 P_Return_Statement): Parse the new syntax for extended_return_statement.
9031 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
9032 Output_End_Missing): Add error-recovery code for the new
9033 extended_return_statement syntax; that is, the new E_Return entry on
9036 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
9037 limited to nonlimited, because otherwise we violate the new Ada 2005
9038 rules about returning limited types in function Create_AST_Handler in
9041 * sem.adb (Analyze): Add cases for new node kinds
9042 N_Extended_Return_Statement and N_Return_Object_Declaration.
9044 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
9045 type is in the same category as type of context before applying check,
9046 to prevent anomalies in instantiations.
9047 (Resolve_Aggregate): Remove test for limited components in aggregates.
9048 It's unnecessary in Ada 95, because if it has limited components, then
9049 it must be limited. It's wrong in Ada 2005, because limited aggregates
9051 (Resolve_Record_Aggregate): Move check for limited types later, because
9052 OK_For_Limited_Init requires its argument to have been resolved.
9053 (Get_Value): When copying the component default expression for a
9054 defaulted association in an aggregate, use the sloc of the aggregate
9055 and not that of the original expression, to prevent spurious
9056 elaboration errors, when the expression includes function calls.
9057 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
9058 were missing. We also didn't handle qualified expressions. Now also
9059 allow function calls. Use new common routine OK_For_Limited_Init.
9060 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
9061 with space can upper case letter).
9063 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
9064 Has_Static_Discriminants flag
9065 (Record_Type_Declaration): Diagnose an attempt to declare an interface
9066 type with discriminants.
9067 (Process_Range_Expr_In_Decl): Do validity checks on range
9068 (Build_Discriminant_Constraints): Use updated form of
9069 Denotes_Discriminant.
9070 (Process_Subtype): If the subtype is a private subtype whose full view
9071 is a concurrent subtype, introduce an itype reference to prevent scope
9073 (Build_Derived_Record_Type, Collect_Interface_Primitives,
9074 Record_Type_Declaration): The functionality of the subprograms
9075 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
9076 is now performed by a single routine.
9077 (Build_Derived_Record_Type): If the type definition includes an explicit
9078 indication of limitedness, then the type must be marked as limited here
9079 to ensure that any access discriminants will not be treated as having
9080 a local anonymous access type.
9081 (Check_Abstract_Overriding): Issue a detailed error message when an
9082 abstract subprogram was not overridden due to incorrect mode of its
9084 (Analyze_Private_Extension_Declaration): Add support for the analysis of
9085 synchronized private extension declarations. Verify that the ancestor is
9086 a limited or synchronized interface or in the generic case, the ancestor
9087 is a tagged limited type or synchronized interface and all progenitors
9088 are either limited or synchronized interfaces.
9089 Derived_Type_Declaration): Check for presence of private extension when
9090 dealing with synchronized formal derived types.
9091 Process_Full_View): Enchance the check done on the usage of "limited" by
9092 testing whether the private view is synchronized.
9093 Verify that a synchronized private view is completed by a protected or
9095 (OK_For_Limited_Init_In_05): New function.
9096 (Analyze_Object_Declaration): Move check for limited types later,
9097 because OK_For_Limited_Init requires its argument to have been resolved.
9098 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
9099 in order to alleviate the upward compatibility introduced by AI-318.
9100 (Constrain_Corresponding_Record): If the constraint is for a component
9101 subtype, mark the itype as frozen, to avoid out-of-scope references to
9102 discriminants in the back-end.
9103 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
9104 this subprogram against wrong sources.
9105 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
9106 discriminant of limited type completed with a protected type, when the
9107 discriminant is used to constrain a private component of the type, and
9108 expansion is disabled.
9109 (Find_Type_Of_Object): Do not treat a return subtype that is an
9110 anonymous subtype as a local_anonymous_type, because its accessibility
9111 level is the return type of the enclosing function.
9112 (Check_Initialization): In -gnatg mode, turn the error "cannot
9113 initialize entities of limited type" into a warning.
9114 (OK_For_Limited_Init): Return true for generated nodes, since it
9115 sometimes violates the legality rules.
9116 (Make_Incomplete_Declaration): If the type for which an incomplete
9117 declaration is created happens to be the currently visible entity,
9118 preserve the homonym chain when removing it from visibility.
9119 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
9120 inherited subprograms.
9121 (Access_Definition): If this is an access to function that is the return
9122 type of an access_to_function definition, context is a type declaration
9123 and the scope of the anonymous type is the current one.
9124 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
9125 incomplete subtype to the set of private dependents of the original
9127 (Constrain_Discriminated_Type): Emit an error message whenever an
9128 incomplete subtype is being constrained.
9129 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
9130 corresponding subtype of the full view of the original incomplete type.
9131 (Check_Incomplete): Properly detect invalid usage of incomplete types
9134 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
9136 * g-catiio.ads, g-catiio.adb (Value): New function.

9145 Robert Dewar <dewar@adacore.com>
9147 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
9148 handling executable extension manually and duplicating code.
9150 * make.adb: Implement new -S switch
9151 (Gnatmake): Use new function Osint.Executable_Name instead
9152 of handling executable extension manually.
9154 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
9155 is specified, the executable name ends with this suffix.
9156 Take advantage of Osint.Executable_Name instead of duplicating code.
9158 * switch-m.adb: Recognize new gnatmake -S switch
9160 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
9162 (Get_Target_Parameters): Set Executable_Extension_On_Target if
9165 * makeusg.adb: Add line for gnatmake -S switch
9167 2006-10-31 Vincent Celier <celier@adacore.com>
9169 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
9170 call it with -static-libgcc, as there are some platforms, such as
9171 Darwin, where one of these two switches is compulsory to link.
9173 2006-10-31 Vincent Celier <celier@adacore.com>
9175 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
9176 instead of ADA_PROJECT_PATH, for the project path.
9177 (Gnatls): When displaying the project path directories, use host dir
9180 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
9181 names in the project path, as absolute paths may correspond to
9182 multi-valued VMS logical names.
9184 2006-10-31 Vincent Celier <celier@adacore.com>
9186 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
9188 (Locate_Regular_File): Ditto
9189 (Change_Dir): Remove, no longer used
9190 (Normalize_Pathname): Do not use Change_Dir to get the drive letter

9193 (Normalize_Pathname)[VMS]: Do not resolve directory names.
9194 (Pid_To_Integer): New function to convert a Process_Id to Integer
9196 2006-10-31 Thomas Quinot <quinot@adacore.com>
9198 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
9199 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
9201 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
9204 2006-10-31 Robert Dewar <dewar@adacore.com>
9206 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
9207 initial letter o as a zero.
9209 2006-10-31 Robert Dewar <dewar@adacore.com>
9211 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
9213 2006-10-31 Robert Dewar <dewar@adacore.com>
9215 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
9217 (Layout_Variant_Record): Retrieve the discriminants from the entity
9218 rather than from the type definition, because in the case of a full
9219 type for a private type we need to take the discriminants from the
9221 (Layout_Component_List): When applying the Max operator to variants with
9222 a nonstatic size, check whether either operand is static and scale that
9223 operand from bits to storage units before applying Max.
9224 (Layout_Type): In VMS, if a C-convention access type has no explicit
9225 size clause (and does not inherit one in the case of a derived type),
9226 then the size is reset to 32 from 64.
9228 2006-10-31 Vincent Celier <celier@adacore.com>
9230 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
9231 its file has already been loaded, according to the unit being loaded,
9232 not to the current value of Multiple_Unit_Index.
9234 2006-10-31 Thomas Quinot <quinot@adacore.com>
9235 Eric Botcazou <ebotcazou@adacore.com>

9260 2006-10-31 Vincent Celier <celier@adacore.com>
9262 * mlib-utl.adb (Initialized): Remove, no longer used
9263 (Initialize): Remove, no longer used
9264 (Ar): If Ar_Exec is null, get the location of the archive builder and,
9265 if there is one, the archive indexer. Fail if the archive builder cannot
9267 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
9270 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9272 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
9273 Process_Body_Clauses): If the context of a body includes a use clause
9274 for P.Q then a with_clause for P in the same body is not redundant,
9275 even if the spec also has a with_clause on P.
9276 Add missing continuation mark to error msg
9277 (Build_Limited_Views): A limited view of a type is tagged if its
9278 declaration includes a record extension.
9279 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
9280 node, even if the subunit has errors. This avoids malfunction by
9281 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
9282 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
9283 generation of obsolescent messages for with statements (cannot do
9284 this too early, or we cannot implement avoiding the messages in the
9285 case of obsolescent units withing obsolescent units).
9286 (Install_Siblings): If the with_clause is on a remote descendant of
9287 an ancestor of the current compilation unit, find whether there is
9288 a sibling child unit that is immediately visible.
9289 (Remove_Private_With_Clauses): New procedure, invoked after completing
9290 the analysis of the private part of a nested package, to remove from
9291 visibility the private with_clauses of the enclosing package
9293 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
9294 now centralized in Generate_Reference.
9295 (Install_Limited_Context_Clauses): Remove superfluous error
9296 message associated with unlimited view visible through use
9297 and renamings. In addition, at the point in which the error
9298 is reported, we add the backslash to the text of the error
9299 to ensure that it is reported as a single error message.
9300 Use new // insertion for some continuation messages
9301 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
9302 to create implicit with_clause for parent unit mentioned in original
9303 limited_with_clause.
9304 (Install_Limited_With_Unit): Set entity of parent identifiers if the
9305 unit is a child unit. For ASIS queries.
9306 (Analyze_Subunit): If the subunit appears within a child unit, make all
9307 ancestor child units directly visible again.

9322 a formal object declaration with an access definition or a subtype mark
9323 with a null exclusion.
9324 (P_Generic_Association): Handle association with box, and others_choice
9325 with box, to support Ada 2005 partially parametrized formal packages.

9335 (P_Type_Declaration): Add the new actual Abstract_Present to every call
9336 to P_Interface_Type_Definition.
9337 (P_Interface_Type_Definition): Addition of one formal to report an error
9338 if the reserved word abstract has been previously found.
9339 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
9340 object renaming declaration with an access definition or subtype mark
9341 with a possible null exclusion.

9360 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
9363 2006-10-31 Vincent Celier <celier@adacore.com>
9365 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
9366 on VMS, change "__" to '.' before checking the name.
9367 (Record_Ada_Source): Always add the source file name in the list of
9368 of sources, even if it is not the first time, as it is for another
9370 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
9371 dot, instead of replacing only the first '_'.
9373 * prj-part.adb (Parse): Convert project file path to canonical form
9375 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
9376 extended, the project id of the project extending it is recorded in its
9377 data, even when it has already been processed as an imported project.
9379 2006-10-31 Robert Dewar <dewar@adacore.com>
9381 * repinfo.adb (List_Entities): Don't list entities from renaming
9384 2006-10-31 Arnaud Charlet <charlet@adacore.com>
9385 Robert Dewar <dewar@adacore.com>
9387 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
9388 only a restriction warning is active for the given restriction. This is
9389 desirable because we do not want to modify code in the case where only
9391 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
9392 causes overriding of real restrictions.
9393 Take advantage of new No_Restrictions constant.
9395 * raise.h: (__gnat_set_globals): Change profile.
9397 2006-10-31 Arnaud Charlet <charlet@adacore.com>

9423 properly an attempt to apply Unchecked_Access to a protected operation.
9424 (OK_Self_Reference): New subprogram to check the legality of an access
9425 attribute whose prefix is the type of an enclosing aggregate.
9426 Generalizes previous mechanism to handle attribute references nested
9427 arbitrarily deep within the aggregate.
9428 (Analyze_Access_Attribute): An access attribute whose prefix is a type
9429 can appear in an aggregate if this is a default-initialized aggregate
9430 for a self-referential type.
9431 (Resolve_Attribute, case Access): Ditto.
9432 Add support for new implementation defined attribute Stub_Type.
9433 (Eval_Attribute, case Attribute_Stub_Type): New case.
9434 (Analyze_Attribute, case Attribute_Stub_Type): New case.
9435 (Stream_Attribute_Available): Implement using new subprogram from

9437 Has_Specified_Stream_Attribute flag.
9438 Disallow Storage_Size and Storage_Pool for access to subprogram
9439 (Resolve_Attribute, case 'Access et al): Take into account anonymous
9440 access types of return subtypes in extended return statements. Remove
9441 accessibility checks on anonymous access types when Unchecked_Access is
9443 (Analyze_Attribute): Add support for the use of 'Class to convert
9444 a class-wide interface to a tagged type.
9445 Add support for the attribute Priority.
9446 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
9447 whether the designated type is discriminated with a constrained partial
9448 view and require static matching in that case.
9449 Add local variable Des_Btyp. The Designated_Type
9450 of an access to incomplete subtype is either its non-limited view if
9451 coming from a limited with or its etype if regular incomplete subtype.
9453 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
9454 Fix predicate to identify and allow cases of (expander-generated)
9455 references to tag of designated object of a RACW.
9456 (Validate_Static_Object_Name): In Ada 2005, a formal object is
9457 non-static, and therefore cannot appear as a primary in a preelaborable
9459 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
9460 Has_Read_Write_Attributes.
9461 (Has_Read_Write_Attributes): Reimplement in termes of
9462 Has_Stream_Attribute_Definition.
9463 (Missing_Read_Write_Attributes): When checking component types in a
9464 record, unconditionally call Missing_Read_Write_Attributes recursively
9465 (remove guard checking for Is_Record_Type / Is_Access_Type).
9467 2006-10-31 Robert Dewar <dewar@adacore.com>
9469 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
9470 useless assignments here and conditionalize it on absence of exception
9472 (Analyze_Exception_Handlers): Small code reorganization of error
9473 detection code, for new handling of formal packages.
9475 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9476 Hristian Kirtchev <kirtchev@adacore.com>
9478 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
9479 that has been constant-folded, preserve information of original tree,
9481 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
9482 generated private extension declaration if the formal derived type is
9483 synchronized. Carry synchronized present over to the generated private
9485 (Validate_Derived_Type_Instance): Ensure that the actual of a
9486 synchronized formal derived type is a synchronized tagged type.
9487 (Instantiate_Formal_Package): When creating the instantiation used to
9488 validate the actual package of a formal declared without a box, check
9489 whether the formal itself depends on a prior actual.
9490 (Instantiate_Formal_Subprogram): Create new entities for the defining
9491 identifiers of the formals in the renaming declaration, for ASIS use.
9492 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
9493 a renaming declaration or a subtype declaration for an actual in an
9494 instance, capture location information of declaration in generic, for
9496 (Instantiate_Formal_Package): Add comments on needed additional tests.
9497 AI-317 (partial parametrization) is fully implemented.
9498 (Validate_Private_Type_Instance): Add check for actual which
9499 must have preelaborable initialization
9500 Use new // insertion for some continuation messages
9501 (Analyze_Formal_Object_Declaration): Change usage of Expression to
9502 Default_Expression. Add type retrieval when the declaration has an
9503 access definition. Update premature usage of incomplete type check.
9504 (Check_Access_Definition): New subsidiary routine. Check whether the
9505 current compilation version is Ada 05 and the supplied node has an
9507 (Instantiate object): Alphabetize local variables. Handle the creation
9508 of new renaming declarations with respect to the kind of definition
9509 used - either an access definition or a subtype mark. Guard against
9510 unnecessary error message in the context of anonymous access types after
9511 they have been resolved. Add check for required null exclusion in a
9512 formal object declaration.
9513 (Switch_View): A private subtype of a non-private type needs to be
9514 switched (the base type can have been switched without its private
9515 dependents because of the last branch of Check_Private_View.
9516 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
9518 (Instantiate_Type): Emit an error message whenever a class-wide type of
9519 a tagged incomplete type is used as a generic actual.
9520 (Find_Actual_Type): Extend routine to handle a component type in a child
9521 unit that is imported from a formal package in a parent.
9522 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
9523 agree on constrainedness, rather than checking against ultimate ancestor
9524 (Instantiate_Subprogram_Body): Create a cross-reference link to the
9525 generic body, for navigation purposes.
9527 2006-10-31 Robert Dewar <dewar@adacore.com>
9528 Thomas Quinot <quinot@adacore.com>
9530 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
9532 (New_Stream_Subprogram): When processing an attribute definition clause
9533 for a stream-oriented subprogram, record an entity node occurring at
9534 the point of clause to use for checking the visibility of the clause,
9535 as defined by 8.3(23) as amended by AI-195.
9536 (New_Stream_Subprogram): New procedure, factoring behaviour from both
9537 New_Stream_Function and New_Stream_Procedure.
9538 (New_Stream_Function, New_Stream_Procedure): Removed.
9539 (Analyze_Attribute_Definition_Clause, case Address): Check new
9540 Alignment_Check check
9542 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9543 Javier Miranda <miranda@adacore.com>
9544 Robert Dewar <dewar@adacore.com>
9546 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
9547 generate the same errors compiling under -gnatc.
9548 (Try_Object_Operation): If no candidate interpretation succeeds, but
9549 there is at least one primitive operation with the right name, report
9550 error in call rather than on a malformed selected component.
9551 (Analyze_Selected_Component): If the prefix is an incomplete type from
9552 a limited view, and the full view is available, use the full view to
9553 determine whether this is a prefixed call to a primitive operation.
9554 (Operator_Check): Verify that a candidate interpretation is a binary
9555 operation before checking the type of its second formal.
9556 (Analyze_Call): Add additional warnings for function call contexts not
9558 (Analyze_Allocator): Move the check for "initialization not allowed for
9559 limited types" after analyzing the expression. This is necessary,
9560 because OK_For_Limited_Init looks at the structure of the expression.
9561 Before analysis, we don't necessarily know what sort of expression it
9562 is. For example, we don't know whether F(X) is a function call or an
9563 indexed component; the former is legal in Ada 2005; the latter is not.
9564 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
9565 were missing. We also didn't handle qualified expressions. Now also
9566 allow function calls. Use new common routine OK_For_Limited_Init.
9567 (Analyze_Type_Conversion): Do not perform some legality checks in an
9568 instance, because the error message will be redundant or spurious.
9569 (Analyze_Overloaded_Selected_Component): Do not do style check when
9570 setting an entity, since we do not know it is the right entity yet.
9571 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
9572 (Analyze_Overloaded_Selected_Component): Same change
9573 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
9574 since regular incomplete subtypes are transformed into corresponding
9575 subtypes of their full views.
9576 (Complete_Object_Operation): Treat name of transformed subprogram call
9577 as coming from source, for browsing purposes.
9578 (Try_Primitive_Operation): If formal is an access parameter, compare
9579 with base type of object to determine whether it is a primitive
9581 (Operator_Check): If no interpretation of the operator matches, check
9582 whether a use clause on any candidate might make the operation legal.
9583 (Try_Class_Wide_Operation): Check whether the first parameter is an
9584 access type whose designated type is class-wide.
9586 2006-10-31 Robert Dewar <dewar@adacore.com>
9587 Ed Schonberg <schonberg@adacore.com>
9588 Gary Dismukes <dismukes@adacore.com>
9590 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
9591 warn on infinite loops.
9592 Add \\ to some continuation messages
9593 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
9594 (Process_Bounds): If the bounds are integer literals that result from
9595 constant-folding, and they carry a user-defined type, preserve that type
9596 rather than treating this as an integer range.
9597 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
9598 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
9599 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
9600 left hand side of assignment.
9601 (Analyze_Assignment): Add suport to manage assigments to the attribute
9602 priority of a protected object.
9603 (Check_Possible_Current_Value_Condition): Allow fully qualified names
9604 not just identifiers.
9605 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
9606 or AND THEN for possible tracking.
9607 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
9608 case of while loops so we can track values in the loop body.
9610 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9611 Hristian Kirtchev <kirtchev@adacore.com>
9612 Bob Duff <duff@adacore.com>
9614 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
9615 procedure cannot be a protected operation (it is a basic_declaration,
9616 not a subprogram_declaration).
9617 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
9618 Subp. Add logic for entry processing.
9619 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
9620 Determine whether an entry or subprogram of a protected or task type
9621 override an inherited primitive of an implemented interface.
9622 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
9623 Update the actual used in calls to Check_Overriding_Indicator.
9624 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
9625 generate the proper reference to the parent unit, for cross-reference.
9626 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
9628 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
9629 (Add_Extra_Formal): Revise procedure to allow passing in associated
9630 entity, scope, and name suffix, and handle setting of the new
9631 Extra_Formals field.
9632 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
9633 pass new parameters. Add support for adding the new extra access formal
9634 for functions whose calls are treated as build-in-place.
9635 (Analyze_A_Return_Statement): Correct casing in error message.
9636 Move Pop_Scope to after Analyze_Function_Return, because an extended
9637 return statement really is a full-fledged scope. Otherwise, visibility
9638 doesn't work right. Correct use of "\" for continuation messages.
9639 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
9640 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
9641 the node doesn't get properly marked as analyzed.
9642 (Analyze_Subprogram_Body): If subprogram is a function that returns
9643 an anonymous access type that denotes a task, build a Master Entity
9645 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
9646 proper usage of null exclusion in a result definition.
9647 (Process_Formals): Code cleanup and new error message.
9648 (Process_Formals): Detect incorrect application of null exclusion to
9650 (Conforming_Types): Handle conformance between [sub]types and itypes
9651 generated for entities that have null exclusions applied to them.
9652 (Maybe_Primitive_Operation): Add an additional type retrieval when the
9653 base type is an access subtype. This case arrises with null exclusions.
9654 (New_Overloaded_Entity): Do not remove the overriden entity from the
9655 homonym chain if it corresponds with an abstract interface primitive.
9656 (Process_Formals): Replace membership test agains Incomplete_Kind with a
9657 call to the synthesized predicate Is_Incomplete_Type.
9658 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
9660 (Analyze_Subprogram_Declaration): Check that abstract interface
9661 primitives are abstract or null.
9662 (Analyze_Subprogram_Specification): Remove previous check for abstract
9663 interfaces because it was not complete.
9664 (Has_Interface_Formals): Removed.
9666 2006-10-31 Ed Schonberg <schonberg@adacore.com>
9667 Javier Miranda <miranda@adacore.com>
9669 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
9670 of Analyze_Package_Body, to create Itype references for anonymous
9671 access types created in the package declaration, whose designated types
9672 may have only a limited view.
9673 (Analyze_Package_Specification): For the private part of a nested
9674 package, install private_with_clauses of enclosing compilation unit if
9675 we are in its visible part.
9676 (Declare_Inherited_Private_Subprograms): Complete barrier
9677 to ensure that the primitive operation has an alias to some parent
9678 primitive. This is now required because, after the changes done for the
9679 implementation of abstract interfaces, the contents of the list of
9680 primitives has entities whose alias attribute references entities of
9681 such list of primitives.
9682 (Analyze_Package_Specification): Simplify code that handles parent units
9683 of instances and formal packages.
9684 (Uninstall_Declarations): Check the convention consistency among
9685 primitive overriding operations of a tagged record type.

9689 Javier Miranda <miranda@adacore.com>
9690 Ed Schonberg <schonberg@adacore.com>
9692 * sem_ch8.adb: Minor error msg rewording
9693 (Undefined): When checking for misspellings, invert arguments (to get
9694 expected and found set right)
9695 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
9696 (Analyze_Generic_Renaming): Same fix
9697 (Use_One_Package): Do not take into account the internal entities of
9698 abstract interfaces during the analysis of entities that are marked
9699 as potentially use-visible.
9700 (Find_Type): Handle the case of an attribute reference for
9701 implementation defined attribute Stub_Type (simply let the analysis of
9702 the attribute reference rewrite it).
9703 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
9704 type that appears in a Use_Type clause.
9705 (Analyze_Object_Renaming): Add support for renaming of the Priority
9707 (Find_Type): In Ada 2005, a task type can be used within its own body,
9708 when it appears in an access definition.
9709 (Analyze_Object_Renaming): Remove warning on null_exclusion.
9710 (Analyze_Object_Renaming): Introduce checks for required null exclusion
9711 in a formal object declaration or in a subtype declaration.
9712 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
9713 (Check_Null_Exclusion): New local routine to
9714 Analyze_Subprogram_Renaming. Check whether the formals and return
9715 profile of a renamed subprogram have required null exclusions when
9716 their counterparts of the renaming already impose them.
9717 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
9718 Determine whether an entity is inside a generic scope.
9719 (In_Open_Scope): First pass of documentation update.
9720 (Find_Expanded_Name): Add support for shadow entities associated with
9721 limited withed packages. This is required to handle nested packages.
9722 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
9723 that makes a renaming of a limited withed package illegal.
9725 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
9726 Ed Schonberg <schonberg@adacore.com>
9728 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
9729 Check_Overriding_Indicator.
9730 (Analyze_Task_Definition): Ditto.
9731 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
9732 (Check_Overriding_Indicator): To find overridden interface operation,
9733 examine only homonyms that have an explicit subprogram declaration, not
9734 inherited operations created by an unrelated type derivation.
9735 (Check_Overriding_Indicator): When checking for the presence of "null"
9736 in a procedure, ensure that the queried node is a procedure
9738 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
9739 type when the formal is an access to variable.
9740 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
9741 (Analyze_Task_Type): Same addition
9742 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
9743 provide navigation capabilities for entries.

9750 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
9751 inherited from an interface ancestor by another interface in the
9752 context of an instance as 'late'.
9753 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
9754 of a call to a function that dispatches on access result.
9755 (Check_Dispatching_Operation): In case of late overriding of a primitive
9756 that covers abstract interface subprograms we register it in all the
9757 secondary dispatch tables associated with abstract interfaces.
9758 (Check_Dispatching_Call): Add check that a dispatching call is not made
9759 to a function with a controlling result of a limited type. This is a
9760 current implementation restriction.
9761 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
9762 (Check_Dispatching_Operation): Do no emit a warning if the controlling
9763 argument is an interface type that is a generic formal.
9764 (Is_Interface_Subprogram): Removed.
9765 (Check_Dispatching_Operation): If the subprogram is not a dispatching
9766 operation, check the formals to handle the case in which it is
9767 associated with an abstract interface type.

9770 Ed Schonberg <schonberg@adacore.com>

9784 Hristian Kirtchev <kirtchev@adacore.com>
9785 Javier Miranda <miranda@adacore.com>
9787 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
9788 subprogram type to provide better diagnostics in case of ambiguity.
9789 (Covers): Handle coverage of formal and actual anonymous access types in
9790 the context of generic instantiation.
9791 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
9792 abstract interface types; this is required to handle concurrent types
9793 with discriminants and abstract interface types.
9794 (Covers): Include type coverage of both regular incomplete subtypes and
9795 incomplete subtypes of incomplete type visibles through a limited with

9799 Hristian Kirtchev <kirtchev@adacore.com>
9800 Ed Schonberg <schonberg@adacore.com>
9802 * sem_util.ads, sem_util.adb (Enter_Name): Exclude -gnatwh warning
9803 messages for entities in packages which are not used.
9804 (Collect_Synchronized_Interfaces): New procedure.
9805 (Overrides_Synchronized_Primitive): New function.
9806 (Denotes_Discriminant): Extend predicate to apply to task types.
9807 Add missing continuation marks in error msgs
9808 (Unqualify): New function for removing zero or more levels of
9809 qualification from an expression. There are numerous places where this
9810 ought to be used, but we currently only deal properly with zero or one
9812 (In_Instance); The analysis of the actuals in the instantiation of a
9813 child unit is not within an instantiation, even though the parent
9814 instance is on the scope stack.
9815 (Safe_To_Capture_Value): Exclude the case of variables that are
9817 (Check_Obsolescent): Removed
9818 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
9819 is an aliased view, even when rewritten as a reference to the target
9820 object in an assignment.
9821 (Get_Subprogram_Entity): New function
9822 (Known_To_Be_Assigned): New function
9823 (Type_Access_Level): Compute properly the access level of a return

9831 Change Is_Lvalue to May_Be_Lvalue
9832 (May_Be_Lvalue): Extensive additional code to deal with subprogram
9833 arguments (IN parameters are not Lvalues, IN OUT parameters are).
9834 (Safe_To_Capture_Value): Extend functionality so it can be used for
9835 the current value condition case.
9836 (Has_Compatible_Alignment): New function
9837 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
9838 objects to handle the Ada 2005 case, where aliasedness no longer implies
9839 that the object is constrained. In particular, for dereferenced names,
9840 the designated object must be assumed to be unconstrained.
9841 (Kill_Current_Values): Properly deal with the case where we encounter
9842 a loop in the scope chain.
9843 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
9845 (Compile_Time_Constraint_Error): Improve error message in error case

9851 2006-10-31 Robert Dewar <dewar@adacore.com>
9853 * s-osinte-tru64.adb:
9854 Mark Asm statements Volatile to prevent warnings (seems a
9855 reasonable change anyway)

9859 Suppresses warning, and seems appropriate in any case
9861 * s-osinte-vms.adb: Add Volatile to Asm statement

9881 (Entity): Add this field for N_Attribute_Definition_Clause.
9882 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
9883 (N_Return_Object_Declaration): Remove this node kind. We now use
9884 N_Object_Declaration instead.
9885 (Actual_Designated_Subtype): Move to a different place to make room in
9886 N_Extended_Return_Statement.
9887 (Procedure_To_Call): Move to a different place to make room in
9888 N_Extended_Return_Statement.
9889 (Return_Type): Removed this field to make room in return statements
9891 (Return_Statement_Entity): New field in return statements, in part to
9892 replace Return_Type, and in part to support the fact that return
9893 statements are now pushed on the scope stack during semantic analysis.
9894 (Return_Object_Declarations): New field to support extended return
9896 (N_Extended_Return_Statement): New node for extended_return_statement
9898 (N_Return_Object_Declaration): New node for part of
9899 extended_return_statement nonterminal. Needed because all the necessary
9900 fields won't fit in N_Extended_Return_Statement.
9901 Generic_associations now carry the Box_Present flag, to indicate a
9902 default for an actual in a partially parametrized formal package.
9904 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
9905 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
9906 and for the new predefined dispatching policies: EDF_Across_Priorities,

9908 Introduce new name Stub_Type for implementation defined attribute.
9909 Add pragma Preelaborable_Initialization
9910 Add entry for Priority attribute.

10500 Robert Dewar <dewar@adacore.com>
10502 * exp_ch4.adb (Expand_N_Allocator): If the allocated object is accessed
10503 through an access to class-wide interface we force the displacement of
10504 the pointer to the allocated object to reference the corresponding
10505 secondary dispatch table.
10506 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,
10507 if Long_Shifts are supported on the target, even if 64 bit divides
10508 are not supported (configurable run time mode).

10528 2006-02-17 Robert Dewar <dewar@adacore.com>
10530 * g-os_lib.adb (Copy_File): Make sure that if From has an Invalid_FD,
10531 then we close To if it is valid.

10541 * Makefile.in: Use VMS64 specialized versions of several units in
10542 Interfaces.C hierarchy to be compatible with HP C default size choices.
10543 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.

10557 Ed Schonberg <schonberg@adacore.com>
10559 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
10560 type we cannot inherit the primitive operations; we inherit the
10561 Corresponding_Record_Type (which has the list of primitive operations).
10562 (Check_Anonymous_Access_Types): When creating anonymous access types for
10563 access components, use Rewrite in order to preserve the tree structure,
10565 (Analyze_Object_Declaration): For limited types with access
10566 discriminants with defaults initialized by an aggregate, obtain
10567 subtype from aggregate as for other mutable types.
10568 (Derived_Type_Declaration): If the derived type is a limited interface,
10569 set the corresponding flag (Is_Limited_Record is not sufficient).

10578 2006-02-17 Javier Miranda <miranda@adacore.com>
10580 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
10581 abstract interface type, the static analysis is not enough to know if
10582 the interface is implemented or not by the source tagged type. Hence
10583 we must pass the work to the expander to generate the required code to
10584 evaluate the conversion at run-time.
10585 (Resolve_Equality_Op): Do not apply previous
10586 transformation if expansion is disasbled, to prevent anomalies when
10587 locating global references in a generic unit.

10767 table to take advantage of the 16 priority levels available on Windows
10768 2000 and XP. On NT4 there are only 7 priority levels, this is properly
10769 supported by this new mapping.

10815 (Read): Change the implementation to support unicode characters. It is
10816 not possible to use strlen() on Windows as this version supports only
10817 standard ASCII characters. So the length of the directory entry is now
10818 returned from the imported __gnat_readdir routine.

10856 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
10857 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
10858 necessary since these are not different types and pointers may
10859 actually designate any subtype in this hierarchy.
10860 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
10861 discriminants but put them into record only if not Unchecked_Union;
10862 pass flag to components_to_record showing Unchecked_Union.
10863 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
10864 components before variants; don't set TYPE_UNCHECKED_UNION_P.

10866 Remove special case code for Unchecked_Union and instead use main code
10867 with small changes.
10870 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
10871 variable with the expression being built, only its inner field.

10874 emit_sequence_entry_statements.

10879 for a subprogram if it has a foreign convention or is exported.
10880 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
10881 substituted for a CONST_DECL.
10882 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
10883 Etype to assoc_to_constructor.
10884 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore

11374 when the parent of a type with discriminants has secondary dispatch
11376 (Init_Secondary_Tags): Handle the case in which the parent of the type
11377 containing secondary dispatch tables has discriminants to generate the
11378 correct arguments to call Set_Offset_To_Top.
11379 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
11381 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
11382 Add Wide_[Wide_]Expanded_Name.
11383 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
11384 the same functionality of Get_Prim_Op_Address but applied to predefined
11385 primitive operations because the pointers to the predefined primitives
11386 are now saved in a separate table.
11387 (Parent_Size): Modified to get access to the separate table of primitive
11388 operations or the parent type.
11389 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
11390 functionality of Set_Prim_Op_Address but applied to predefined primitive
11392 (Set_Signature): New subprogram used to store the signature of a DT.
11393 (Displace): If the Offset_To_Top value is not static then call the
11394 function generated by the expander to get such value; otherwise use
11395 the value stored in the table of interfaces.
11396 (Offset_To_Top): The type of the actual has been changed to Address to
11397 give the correct support to tagged types with discriminants. In this
11398 case this value is stored just immediately after the tag field.
11399 (Set_Offset_To_Top): Two new formals have been added to indicate if the
11400 offset_to_top value is static and hence pass this value to the run-time
11401 to store it in the table of interfaces, or else if this value is dynamic
11402 and then pass to the run-time the address of a function that is
11403 generated by the expander to provide this value for each object of the
11406 * rtsfind.ads (Default_Prin_Op_Count): Removed.
11407 (Default_Prim_Op_Count): New entity
11408 (Get_Predefined_Prim_Op_Address): New entity
11409 (Set_Predefined_Prim_Op_Address): New entity
11410 (RE_Set_Signature): New entity
11412 2006-02-13 Thomas Quinot <quinot@adacore.com>
11413 Ed Schonberg <schonberg@adacore.com>
11415 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
11416 Make_Adjust_Call done for a newly-allocated object.
11418 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
11419 in a subprogram are wrapped in a cleanup block, indicate that the
11420 subprogram contains an inner block with an exception handler.
11421 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
11422 Adjust call is for a newly-allocated object. In that case we must not
11423 assume that the finalization list chain pointers are correct (since they
11424 come from a bit-for-bit copy of the original object's pointers) so if
11425 the attach level would otherwise be zero (no change), we set it to 4
11426 instead to cause the pointers to be reset to null.
11428 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
11429 reset chain pointers to null.
11431 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11433 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
11434 string, and the context requires a loop for the assignment (e.g.
11435 because the left-hand side is packed), generate a unique name for the
11436 temporary that holds the string, to prevent spurious name clashes.
11438 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11439 Javier Miranda <miranda@adacore.com>
11440 Robert Dewar <dewar@adacore.com>
11441 Gary Dismukes <dismukes@adacore.com>
11443 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
11444 return unconstrained arrays.
11446 (Expand_Call): An indirect call through an access parameter of a
11447 protected operation is not a protected call.
11448 Add circuit to raise CE in Ada 2005 mode following call
11449 to Raise_Exception.
11450 (Register_DT_Entry): Do nothing if
11451 the run-time does not give support to abstract interfaces.
11452 (Freeze_Subprogram): In case of dispatching operations, do not generate
11453 code to register the operation in the dispatch table if the source
11454 is compiled with No_Dispatching_Calls.
11455 (Register_Predefined_DT_Entry): Generate code that calls the new
11456 run-time subprogram Set_Predefined_Prim_Op_Address instead of
11457 Set_Prim_Op_Address.
11459 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
11460 on array assignments if the right-hand side is a function call that has
11461 been inlined. Check is performed on the assignment in the block.
11462 (Process_Bounds): If bounds and range are overloaded, apply preference
11463 rule for root operations to disambiguate, and diagnose true ambiguity.
11464 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
11465 a tag-indeterminate right-hand side even when Expander_Active is True.
11466 Needed to ensure that dispatching calls to T'Input are allowed and
11467 get the tag of the target class-wide object.
11469 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
11470 an inherited primitive operation that already overrides several
11471 abstract interface primitives. For transitivity, the new entity must
11472 also override all the abstract interface primitives covered by the
11473 inherited overriden primitive.
11474 Emit warning if new entity differs from homograph in same scope only in
11475 that one has an access parameter and the other one has a parameter of
11476 a general access type with the same designated type, at the same
11477 position in the signature.
11478 (Make_Inequality_Operator): Use source locations of parameters and
11479 subtype marks from corresponding equality operator when creating the
11480 tree structure for the implicit declaration of "/=". This does not
11481 change anything in behaviour except that the decoration of the
11482 components of the subtree created for "/=" allows ASIS to get the
11483 string images of the corresponding identifiers.
11484 (Analyze_Return_Statement): Remove '!' in warning message.
11485 (Check_Statement_Sequence): Likewise.
11486 (Analyze_Subprogram_Body): For an access parameter whose designated type
11487 is an incomplete type imported through a limited_with clause, use the
11488 type of the corresponding formal in the body.
11489 (Check_Returns): Implicit return in No_Return procedure now raises
11490 Program_Error with a compile time warning, instead of beging illegal.
11491 (Has_Single_Return): Function returning unconstrained type cannot be
11492 inlined if expression in unique return statement is not an identifier.
11493 (Build_Body_To_Inline): It is possible to inline a function call that
11494 returns an unconstrained type if all return statements in the function
11495 return the same local variable. Subsidiary procedure Has_Single_Return
11496 verifies that the body conforms to this restriction.
11498 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
11499 same type, and one of them is of an anonymous access type, convert
11500 the other operand to it, so that this is a valid binary operation for
11502 (Resolve_Type_Conversion): Handle subtypes of protected types and
11503 task types when accessing to the corresponding record type.
11504 (Resolve_Allocator): Add '\' in 2-line warning message.
11505 Remove '!' in warning message.
11506 (Resolve_Call): Add '\' in 2-line warning message.
11507 (Valid_Conversion): Likewise.
11508 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
11509 resulting type may be an access type with an implicit dereference.
11510 Obtain the proper component from the designated type.
11511 (Make_Call_Into_Operator): Handle properly a call to predefined equality
11512 given by an expanded name with prefix Standard, when the operands are
11513 of an anonymous access type.
11514 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
11515 Explicit_Dereference and Resolve_Selected_Component, to verify that the
11516 prefix of the expression is not of an incomplete type. Allows full
11517 diagnoses of all semantic errors.
11518 (Resolve_Actuals): If the actual is an allocator whose directly
11519 designated type is a class-wide interface we build an anonymous
11520 access type to use it as the type of the allocator. Later, when
11521 the subprogram call is expanded, if the interface has a secondary
11522 dispatch table the expander will add a type conversion to force
11523 the displacement of the pointer.
11524 (Resolve_Call): If a function that returns an unconstrained type is
11525 marked Inlined_Always and inlined, the call will be inlined and does
11526 not require the creation of a transient scope.
11527 (Check_Direct_Boolean_Op): Removed
11528 (Resolve_Comparison_Op): Remove call to above
11529 (Resolve_Equality_Op): Remove call to above
11530 (Resolve_Logical_Op): Inline above, since this is only call.
11531 (Valid_Conversion): Handle properly conversions between arrays of
11532 convertible anonymous access types.
11535 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
11536 the literal in an unchecked conversion, because GCC 4.x needs a static
11537 value for a string bound.
11539 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11540 Hristian Kirtchev <kirtchev@adacore.com>
11542 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
11543 components of the corresponding record, take into account component
11544 definitions that are access definitions.
11545 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
11546 procedure is not considered a dispatching call and will be expanded
11549 2006-02-13 Javier Miranda <miranda@adacore.com>
11551 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
11552 controlling argument of the dispatching call is an abstract interface
11553 class-wide type then we use it directly.
11554 Check No_Dispatching_Calls restriction.
11555 (Default_Prim_Op_Position): Remove the code that looks for the last
11556 entity in the list of aliased subprograms. This code was wrong in
11558 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
11559 when the source is compiled with the No_Dispatching_Calls restriction.
11560 (Init_Predefined_Interface_Primitives): No need to inherit primitives
11561 if we are compiling with restriction No_Dispatching_Calls.
11562 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
11563 subprograms if we are compiling under No_Dispatching_Calls restriction.
11564 (Make_DT): Generate a dispatch table with a single dummy entry if
11565 we are compiling with the No_Dispatching_Calls restriction. In
11566 addition, in this case we don't generate code that calls to the
11567 following run-time subprograms: Set_Type_Kind, Inherit_DT.
11568 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
11569 of this subprogram if compiling with the No_Dispatching_Calls
11571 (Expand_Type_Conversion): Instead of using the actual parameter,
11572 the argument passed as parameter to the conversion function was
11573 erroneously referenced by the expander.
11574 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
11575 Set_Predefined_Primitive_Op_Address and Set_Signature.
11576 (Expand_Dispatching_Call): Generate call to
11577 Get_Predefined_Prim_Op_Address for predefined primitives.
11578 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
11579 predefined primitives.
11580 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
11581 primitives we reserve one dummy entry to ensure that the tag does not
11582 point to some memory that is associated with some other object. In
11583 addition, remove all the old code that generated the assignments
11584 associated with the signature of the dispatch table and replace them
11585 by a call to the new subprogram Set_Signature.
11586 (Set_All_DT_Position): Change the algorithm because now we have a
11587 separate dispatch table associated with predefined primitive operations.
11588 (Expand_Interface_Conversion): In case of non-static offset_to_top
11589 add explicit dereference to get access to the object after the call
11590 to displace the pointer to the object.
11591 (Expand_Interface_Thunk): Modify the generation of the actual used
11592 in the calls to the run-time function Offset_To_Top to fulfil its
11594 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
11596 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11598 * exp_dist.adb (Copy_Specification): For access parameters, copy
11599 Null_Exclusion flag, which will have been set for stream subprograms
11602 2006-02-13 Pascal Obry <obry@adacore.com>
11604 * expect.c (__gnat_expect_portable_execvp): New implementation. The
11605 previous implementation was using the C runtime spawnve routine but
11606 the corresponding wait was using directly the Win32 API. This was
11607 causing some times a lock when waiting for an event using
11608 WaitForSingleObject in __gnat_waitpid. This new implementation uses
11609 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
11610 API fixes this problem.
11612 2006-02-13 Robert Dewar <dewar@adacore.com>
11614 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

11622 array reference that is an explicit dereference, mark the converted
11623 (packed) array reference as analyzed to prevent a forthcoming
11624 reanalysis from resetting its type to the original (non-packed) array

11628 Javier Miranda <miranda@adacore.com>
11629 Eric Botcazou <ebotcazou@adacore.com>
11631 * exp_util.ads, exp_util.adb (Find_Prim_Op,
11632 Is_Predefined_Primitive_Operation): When
11633 searching for the predefined equality operator, verify that operands
11634 have the same type.
11635 (Is_Predefined_Dispatching_Operation): Remove the code that looks
11636 for the last entity in the list of aliased subprograms. This code
11637 was wrong in case of renamings.
11638 (Set_Renamed_Subprogram): New procedure
11639 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
11640 Exp_Type constant computed when entering this subprogram.

11642 (OK_To_Do_Constant_Replacement): New function
11643 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
11644 (Side_Effect_Free): An attribute reference 'Input is not free of
11645 side effect, unlike other attributes that are functions. (from code
11647 (Remove_Side_Effects): Expressions that involve packed arrays or records
11648 are copied at the point of reference, and therefore must be marked as
11649 renamings of objects.
11650 (Is_Predefined_Dispatching_Operation): Return false if the operation is
11651 not a dispatching operation.
11654 (Remove_Side_Effects): Lift enclosing type conversion nodes for
11655 elementary types in all cases.
11657 2006-02-13 Javier Miranda <miranda@adacore.com>
11659 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
11660 task types when accessing to the corresponding record type.
11661 Remove '!' in warning message.
11663 2006-02-13 Olivier Hainque <hainque@adacore.com>
11665 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
11666 to avoid useless and space inefficient overalignments on targets where
11667 Max_Alignment is larger than 16.
11669 2006-02-13 Pascal Obry <obry@adacore.com>
11671 * g-catiio.adb (Sec_Number): New type used to compute the number of
11672 seconds since 1-1-1970.
11673 (Image) [Natural]: The parameter was an Integer, as we can't deal with
11674 negative numbers (years, months...) it is better to have a Natural here.
11676 (Image) [Number]: Change parameter from Long_Integer to Number.
11677 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
11678 overflow for dates past year 2038.
11680 2006-02-13 Matthew Heaney <heaney@adacore.com>
11682 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
11685 2006-02-13 Arnaud Charlet <charlet@adacore.com>
11687 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
11689 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
11690 finalization can occur normally.
11692 2006-02-13 Vincent Celier <celier@adacore.com>
11694 * gnatcmd.adb (Rules_Switches): New table
11695 (Add_To_Rules_Switches): New procedure
11696 (GNATCmd): For command CHECK, put all options following "-rules" in the
11697 Rules_Switches table. Append these -rules switches after the -cargs
11700 2006-02-13 Robert Dewar <dewar@adacore.com>
11702 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
11703 These two cases were generating incorrect output, and if this unit
11704 was built with checks on, generated a discriminant mismatch constraint
11707 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11708 Robert Dewar <dewar@adacore.com>
11710 * lib-xref.adb (Get_Type_Reference): For a private type whose full
11711 view is an array type, indicate the component type as well, for
11712 navigation purposes.

11714 of violating pragma Unreferenced.
11715 Do not give Ada 2005 warning except on real reference.

11719 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
11720 main source, add switch -mdebug-main=_ada_ so that the executable can
11721 be debugged by the standard VMS debugger.
11722 (Gnatmake): Set No_Main_Subprogram to True when there is no main
11723 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
11724 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
11725 of the last source, as the binding and linking phases are never
11727 Set all executable obsolete when rebuilding a library.
11729 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
11732 2006-02-13 Javier Miranda <miranda@adacore.com>
11735 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
11736 code to improve the error message reported when the program has
11737 declarations of abstract interface types and it is not compiled with
11738 the -gnat05 switch.
11739 (P_Access_Definition): Reorganize the code to improve the error
11740 message reported when the new Ada 2005 syntax for anonymous
11741 access types is used and the program is not compiled with the

11758 the standard naming data.
11760 2006-02-13 Vincent Celier <celier@adacore.com>
11762 * prj.ads (Error_Warning): New enumeration type
11764 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
11765 unknown, use the location of the project to report the error.

11781 Prj.Nmsc.Check with parameter When_No_Sources.
11782 (Process): New parameter When_No_Sources. Call Check with parameter

11794 When removing nodes (attributes Source_Dirs, Source_Files,
11795 Source_List_File and package Naming), save the comments and attach the
11796 saved comments to the newly created nodes.
11797 Do not add a with clause for the naming package if one already exists.

11810 operation in the dispatch table if the source is compiled with
11811 restriction No_Dispatching_Calls.
11812 (Override_Dispatching_Operation): Check for illegal attempt to override
11813 No_Return procedure with procedure that is not No_Return
11814 (Check_Dispatching_Call): Suppress the check for an abstract operation
11815 when the original node of an actual is a tag-indeterminate attribute
11816 call, since the attribute, which must be 'Input, can never be abstract.
11817 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
11818 call to the Input attribute (even when rewritten).
11819 (Propagate_Tag): Augment comment to indicate the possibility of a call
11820 to an Input attribute.
11822 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
11823 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
11825 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
11826 No_Wide_Characters is no longer partition-wide

11832 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
11834 2006-02-13 Javier Miranda <miranda@adacore.com>
11836 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
11837 handles default-initialized components to keep separate the management
11838 of this feature but also avoid the unrequired resolution and
11839 expansion of components that do not have partially initialized
11841 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
11842 (Check_Bounds): Likewise.
11843 (Check_Length): Likewise.

11846 Ed Schonberg <schonberg@adacore.com>
11848 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
11849 abstract interface type call analyze_and_resolve to expand the type
11850 conversion into the corresponding displacement of the
11851 reference to the base of the object.
11852 (Eval_Attribute, case Width): For systems where IEEE extended precision
11853 is supported, the maximum exponent occupies 4 decimal digits.
11854 (Accessibility_Message): Add '\' in 2-line warning message.
11855 (Resolve_Attribute): Likewise.
11856 (case Attribute_Access): Significantly revise checks
11857 for illegal access-to-subprogram Access attributes to properly enforce
11858 the rules of 3.10.2(32/2).
11859 Diagnose use of current instance with an illegal attribute.
11861 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
11863 (Enclosing_Generic_Unit): New function to return a node's innermost
11864 enclosing generic declaration node.
11865 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
11866 (Type_Access_Level): The accessibility level of anonymous acccess types
11867 associated with discriminants is that of the current instance of the
11868 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
11869 (Compile_Time_Constraint_Error): Handle case of conditional expression.
11870 (Kill_Current_Values_For_Entity): New function
11871 (Enter_Name): Change formal type to Entity_Id

11877 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
11878 Analyze_Compilation_Unit.
11879 Detect and warn on redundant with clauses detected in a package spec
11880 and/or body when -gnatwr is used.
11881 (Analyze_Context): Analyze config pragmas before other items
11882 (Install_Context_Items): Don't analyze config pragmas here
11883 (Install_Limited_Withed_Unit): Set limited entity of package in
11884 with_clause so that cross-reference information or warning messages on
11885 unused packages can be properly generated
11886 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
11887 has Error_Posted set. Prevent infinite loops in illegal programs.
11888 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
11889 to the point of the error test requiring the current unit to be private.
11890 This ensures that private with clauses are not exempted from the basic
11891 checking for being a descendant of the same library unit parent as a
11892 withed private descendant unit.
11893 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
11894 handle private with clauses properly, as well as to account for cases
11895 where the withed unit is a public descendant of a private ancestor
11896 (in which case the current unit must be a descendant of the private
11897 ancestor's parent). The spec comments were updated accordingly. Also,
11898 the old error message in this subprogram was replaced with error
11899 messages that mirror the errors tested and reported by
11900 Check_Private_Child_Unit.
11901 Parameter and variable names improved for readability.
11902 (Install_Limited_Context_Clauses): Remove test for a withed unit being
11903 private as the precondition for calling
11904 Check_Private_Limited_Withed_Unit since that subprogram has been
11905 revised to test public units as well as private units.

11910 Javier Miranda <miranda@adacore.com>
11912 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
11913 that Scope_Stack.First = 1.
11914 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
11915 were not always properly handled previously.
11916 (Formal_Entity): Complete rewrite, to handle properly some complex case
11917 with multiple levels of parametrization by formal packages.
11918 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
11919 to the corresponding derived type declaration for proper semantics.
11921 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
11922 (Check_Component): Enforce restriction on components of
11923 unchecked_unions: a component in a variant cannot contain tasks or
11925 (Unchecked_Union): Allow nested variants and multiple discriminants, to
11927 Add pragma Ada_2005 (synonym for Ada_05)
11928 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
11929 were not always properly handled previously.
11930 Document that pragma Propagate_Exceptions has no effect
11931 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
11932 (Set_Convention_From_Pragma): Check that if a convention is
11933 specified for a dispatching operation, then it must be
11934 consistent with the existing convention for the operation.
11935 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
11936 longer required to specify an vtable-ptr component in the record. For
11937 compatibility reasons we leave the support for the previous definition.
11938 (Analyze_Pragma, case No_Return): Allow multiple arguments
11940 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
11941 non-overrideen inherited operation with a controlling result as
11942 illegal only its implicit declaration comes from the derived type
11943 declaration of its result's type.
11944 (Check_Possible_Deferred_Completion): Relocate the object definition
11945 node of the subtype indication of a deferred constant completion rather
11946 than directly analyzing it. The analysis of the generated subtype will
11947 correctly decorate the GNAT tree.
11948 (Record_Type_Declaration): Check whether this is a declaration for a
11949 limited derived record before analyzing components.
11950 (Analyze_Component_Declaration): Diagnose record types not explicitly
11951 declared limited when a component has a limited type.
11952 (Build_Derived_Record_Type): Code reorganization to check if some of
11953 the inherited subprograms of a tagged type cover interface primitives.
11954 This check was missing in case of a full-type associated with a private
11956 (Constant_Redeclaration): Check that the subtypes of the partial and the
11957 full view of a constrained deferred constant statically match.
11958 (Mentions_T): A reference to the current type in an anonymous access
11959 component declaration must be an entity name.
11960 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
11961 class_wide type to refer to full type, not to the incomplete one.
11962 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
11963 available. Required to give support to the certified run-time.
11964 (Analyze_Component_Declaration): In case of anonymous access components
11965 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
11966 (Process_Discriminants): For an access discriminant, use the
11967 discriminant specification as the associated_node_for_itype, to
11968 simplify accessibility checks.
11970 2006-02-13 Ed Schonberg <schonberg@adacore.com>
11971 Javier Miranda <miranda@adacore.com>
11973 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
11974 abstract interpretations on an operator, remove interpretations that
11975 yield Address or a type derived from it, if one of the operands is an
11977 (Try_Object_Operation.Try_Primitive_Operation,
11978 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
11979 location when creating the new reference to a primitive or class-wide
11980 operation as a part of rewriting a subprogram call.
11981 (Try_Primitive_Operations): If context requires a function, collect all
11982 interpretations after the first match, because there may be primitive
11983 operations of the same type with the same profile and different return
11984 types. From code reading.
11985 (Try_Primitive_Operation): Use the node kind to choose the proper
11986 operation when a function and a procedure have the same parameter
11988 (Complete_Object_Operation): If formal is an access parameter and prefix
11989 is an object, rewrite as an Access reference, to match signature of
11990 primitive operation.
11991 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
11992 by an expanded name with prefix Standard, when the operands are of an
11993 anonymous access type.
11994 (Remove_Abstract_Operations): If the operation is abstract because it is
11995 inherited by a user-defined type derived from Address, remove it as
11996 well from the set of candidate interpretations of an overloaded node.
11997 (Analyze_Membership_Op): Membership test not applicable to cpp-class
12000 2006-02-13 Bob Duff <duff@adacore.com>
12002 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
12003 redundant use clauses.
12004 In particular, if the scope of two use clauses overlaps, but one is not
12005 entirely included in the other, we should not warn. This can happen
12006 with nested packages.
12007 (Analyze_Subprogram_Renaming): Protect the compiler against previously
12008 reported errors. The bug was reported when the compiler was built
12009 with assertions enabled.
12010 (Find_Type): If the node is a 'Class reference and the prefix is a
12011 synchronized type without a corresponding record, return the type
12014 2006-02-13 Javier Miranda <miranda@adacore.com>
12016 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
12017 if this is the full-declaration associated with a private declaration
12018 that implement interfaces, then the private type declaration must be
12020 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
12021 as aliased. The use of the 'access attribute is not available for such
12022 object (for this purpose the object should be explicitly marked as
12023 aliased, but being an anonymous type this is not possible).
12025 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12026 Robert Dewar <dewar@adacore.com>
12028 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
12029 compilation unit is an elaboration scope.
12030 (Add_Task_Proc): Add '\' in 2-line warning message.
12031 (Activate_All_Desirable): Deal with case of unit with'ed by parent
12033 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12034 Javier Miranda <miranda@adacore.com>
12036 * sem_type.adb (Write_Overloads): Improve display of candidate
12038 (Add_One_Interp): Do not add to the list of interpretations aliased
12039 entities corresponding with an abstract interface type that is an
12040 immediate ancestor of a tagged type; otherwise we have a dummy
12041 conflict between this entity and the aliased entity.
12042 (Disambiguate): The predefined equality on universal_access is not
12043 usable if there is a user-defined equality with the proper signature,
12044 declared in the same declarative part as the designated type.
12045 (Find_Unique_Type): The universal_access equality operator defined under
12046 AI-230 does not cover pool specific access types.
12047 (Covers): If one of the types is a generic actual subtype, check whether
12048 it matches the partial view of the other type.
12050 2006-02-13 Thomas Quinot <quinot@adacore.com>
12052 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
12053 line. This is necessary to allow In_Extended_Main_Unit to provide
12054 correct results for itypes while writing out expanded source.
12055 (Close_File): No need to update the source_index_table here since it's
12056 now done for each line.
12058 2006-02-13 Ed Schonberg <schonberg@adacore.com>
12059 Robert Dewar <dewar@adacore.com>
12061 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
12062 preserve the source unit where the itype is declared, and prevent a

12072 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
12075 2006-02-13 Bob Duff <duff@adacore.com>
12077 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
12078 Scan_Unsigned, so we do not scan leading blanks and sign twice.
12079 Integer'Value("- 5") and Integer'Value("-+5") now correctly
12080 raise Constraint_Error.
12082 * s-vallli.adb (Scan_Long_Long_Integer): Call
12083 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
12084 do not scan leading blanks and sign twice.
12085 Integer'Value("- 5") and Integer'Value("-+5") now correctly
12086 raise Constraint_Error.
12088 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
12089 Scan_Long_Long_Unsigned): Split out most of the processing from
12090 Scan_Long_Long_Unsigned out into
12091 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
12092 This prevents scanning leading blanks and sign twice.
12093 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
12096 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
12097 out most of the processing from Scan_Unsigned out into
12098 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
12099 This prevents scanning leading blanks and sign twice.
12101 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
12102 use with Modular'Value attribute.
12103 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

12317 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
12318 non-tasking version of the soft link for task termination. We do
12319 nothing since if we are using the non-tasking version it

12321 (Null_Finalize_Global_List): Add this null version for the procedure
12322 in charge of finalizing the global list for controlled objects.

12324 instead for handling run-time termination in a more flexible way.
12325 (Adafinal_NT): This new procedure will take care of finalizing the
12326 global list for controlled objects if needed, but no tasking
12329 * s-tarest.adb (Task_Lock): Do not try to lock again the
12330 Global_Task_Lock if we already own it. Otherwise, we get blocked in
12331 some run-time operations.
12332 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
12333 until all nested locks have been released.
12334 (Task_Wrapper): Call the fall-back task termination handler. It
12335 applies to all tasks but the environment task.

12337 procedure for the environment task.
12338 (Task_Wrapper): suppress warnings around declaration of

12342 moved to the Common_ATCB record.
12343 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
12344 Common_ATCB record.
12345 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the

12354 Ada.Task_Termination, for avoiding circular dependencies.
12355 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
12356 for storing task termination handlers. In addition,
12357 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to

12371 using the soft links mechanism.
12372 (Task_Wrapper): added dynamic stack analysis.
12374 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
12375 potentially blocking operations has been moved from
12376 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
12377 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
12378 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
12379 this run-time check.
12381 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
12382 of task termination procedure.

12430 (Displace): New subprogram that displaces the pointer to the object
12431 to reference one of its secondary dispatch tables.
12432 (IW_Membership): Modified to use the new table of interfaces.
12433 (Inherit_TSD): Modified to use the new table of interfaces.
12434 (Register_Interface_Tag): Use the additional formal to fill the
12435 contents of the new table of interfaces.
12436 (Set_Interface_Table): New subprogram that stores in the TSD the

12451 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
12452 in all the calls to Expand_Interface_Thunk. Instead of referencing the
12453 record component containing the tag of the secondary dispatch table we
12454 have to use the Offset_To_Top run-time function to get this information;
12455 otherwise if the pointer to the base of the object has been displace
12456 we get a wrong value if we use the 'position attribute.
12458 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
12459 all the calls to Expand_Interface_Thunk.
12460 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

12463 ensure that the interfaces implemented by the ancestors are placed
12464 at the header of the generated list.
12465 (Expand_Interface_Conversion): Handle the case in which the displacement
12466 associated with the interface conversion is not statically known. In
12467 this case we generate a call to the new run-time subprogram Displace.

12494 RE_TK_Tagged, RE_TK_Task.
12496 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
12497 Init_Secondary_Tags_Internal to allow its use with interface types and
12498 also to generate the code for the new additional actual required
12499 by Set_Offset_To_Top.
12500 (Build_Init_Statements): In case of components associated with abstract
12501 interface types there is no need to generate a call to its IP.

12513 properly protected objects and attach handler in the case of the
12514 restricted profile.
12515 Move embeded package Select_Expansion_Utilities into a separate external

12527 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
12528 pointer initialization values. Make a SAVE_EXPR instead. Add comments
12529 about the use and expansion of SAVE_EXPRs in the various possible
12530 renaming handling cases.
12531 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
12532 abusing DECL_FCONTEXT.

12700 legal within a protected type that implements an interface.
12701 (Collect_Interfaces): Do not add to the list the interfaces that
12702 are implemented by the ancestors.
12703 (Derived_Type_Declaration): If the parent of the full-view is an
12704 interface perform a transformation of the tree to ensure that it has
12705 the same parent than the partial-view. This simplifies the job of the
12706 expander in order to generate the correct object layout, and it is
12707 needed because the list of interfaces of the full-view can be given in
12709 (Process_Full_View): The parent of the full-view does not need to be
12710 a descendant of the parent of the partial view if both parents are
12712 (Analyze_Private_Extension_Declaration): If declaration has an explicit
12713 "limited" the parent must be a limited type.
12714 (Build_Derived_Record_Type): A derived type that is explicitly limited
12715 must have limited ancestor and progenitors.

12787 available user-specified stream attributes on limited parameters to
12788 also test the type directly rather than only its underlying type (for
12789 Ada 95) and, in the case of Ada 2005, to check that the user-specified
12790 attributes are visible at the point of the subprogram declaration.
12791 For Ada 2005, the error message is modified to indicate that the
12792 type's stream attributes must be visible (again, only for -gnat05).

12824 types use the corresponding record type. This was not needed before
12825 the implementation of Ada 2005 synchronized types because
12826 concurrent types were never tagged types in Ada 95.

12954 * socket.c: Add extern int h_errno for rtems since networking header
12955 files are not available at this point in a tool bootstrap. Newlib
12956 only has basic C library header files.

13050 TARGET, as it has the form of a math expression, and some components
13051 may be platform-defined macros.
13052 For VxWorks, generate the OK and ERROR values.
13053 New constants giving the sizes of the components of C struct timeval.

13065 deal with different cases of static and dynamic elaboration checks (all
13066 checks does not count in the first case, but does in the second).

13072 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
13073 elementary types using the operator in standard. It is cleaner not to
13074 modify the programmers intent, especially in the case of floating-point.
13075 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
13076 it did not matter because we always rewrote a/=b to not(a=b).
13077 (Expand_Allocator_Expression): For an allocator expression whose nominal
13078 subtype is an unconstrained packed type, convert the expression to its
13079 actual constrained subtype.
13080 Implement warning for <= or >= where < or > not possible
13081 Fix to Vax_Float tests (too early in many routines, causing premature
13082 Vax_Float expansions.
13084 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
13085 to be used with packages and generic packages as well as with

13100 Allow optional = after -gnatm
13101 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
13102 longer sets Elaboration_Checks.
13103 Code to set warning mode moved to Sem_Warn
13104 so that it can be shared by pragma processing.
13106 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
13109 * s-taprop-solaris.adb:
13110 Change some <= to =, to avoid new warning

13118 * exp_vfpt.adb: Handle /= case
13119 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
13120 so that we do not get duplicate scaling for fixed point conversions.
13122 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
13124 2005-11-14 Matthew Gingell <gingell@adacore.com>
13126 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
13127 Increase default priority on Lynx from 15 to 17, and meet the Ada
13128 requirement that Default_Priority be ((Priority'First +
13129 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

13221 Olivier Hainque <hainque@adacore.com>
13222 Eric Botcazou <ebotcazou@adacore.com>
13225 Factor common code to build a storage type for an unconstrained object
13226 from a fat or thin pointer type and a constrained object type.
13227 (annotate_value): Handle BIT_AND_EXPR.
13228 (annotate_rep): Don't restrict the back annotation of inherited
13229 components to the type_annotate_only case.
13230 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
13231 we are not defining the type.
13232 <E_Record_Type>: Likewise.
13233 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
13234 to get advantage of the new maybe_stabilize_reference interface, to
13235 ensure that what we reference is indeed stabilized instead of relying
13236 on assumptions on what the stabilizer does.
13237 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
13238 type imported through a limited_with clause, use its non-limited view.
13239 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
13241 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
13242 of #if sections + explicit comparisons of convention identifiers.
13243 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
13244 before early-returning for certain types when code generation is
13246 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
13247 nullification of gnu_expr we do for objects with address clause and
13248 that we are not defining.
13249 (elaborate_expression_1): Do not create constants when creating
13250 variables needed by the debug info: the dwarf2 writer considers that
13251 CONST_DECLs is used only to represent enumeration constants, and emits
13253 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
13254 object with an address clause into an indirect reference, drop the
13255 initializing expression.
13257 (STACK_CHECK_BUILTIN): Delete.
13258 (STACK_CHECK_PROBE_INTERVAL): Likewise.

13266 if there is an actual subtype provided by the front-end, use that
13267 subtype to build an actual type with bounds template.
13268 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
13269 is provided by the front-end, use that subtype to compute the size of
13270 the deallocated object.
13271 (gnat_to_gnu): When adding a statement into an elaboration procedure,
13272 check for a potential violation of a No_Elaboration_Code restriction.
13273 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
13274 with extra arguments to control whether to recurse through non-values
13275 and to let the caller know if the stabilization has succeeded.

13277 maybe_stabilize, for common uses without restriction on lvalues and
13278 without need to check for the success indication.
13279 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
13280 pass false instead of 0 as the FORCE argument which is a bool.
13281 (Identifier_to_gnu): Remove checks ensuring that an renamed object
13282 attached to a renaming pointer has been properly stabilized, as no such
13283 object is attached otherwise.
13284 (call_to_gnu): Invoke create_var_decl to create the temporary when the
13285 function uses the "target pointer" return mechanism.
13286 Reinstate conversion of the actual to the type of the formal
13287 parameter before any other specific treatment based on the passing
13288 mechanism. This turns out to be necessary in order for PLACEHOLDER
13289 substitution to work properly when the latter type is unconstrained.

13298 static output of record constructor if all the components are constant.
13299 (gnat_build_constructor): For a record type, sort the list of field

13512 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
13513 'Terminated for task interface class-wide objects. Generate a call to
13514 the predefined dispatching routine used to retrieve the _task_id from

13544 the return value into its actual subtype in order to help the backend

13575 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

13595 attribute of the N_Free_Statement.
13596 Generate itype for classwide designated object in both cases of

13779 rhs of an assignment even if the type is unconstrained, when the
13780 context is non-expanding.
13781 In an inlined body, if the context type is private,
13782 resolve with its full view, which must be a composite type.

13793 circular lists of Use_Clauses in a parent.
13794 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
13795 compiling body of child unit.
13796 Use new class N_Subprogram_Instantiation

13819 (Inline_Instance_Body): Deinstall and record the use_clauses for all
13820 parent scopes of a scope being removed prior to inlining an instance
13822 (Analyze_Package_Instantiation): Do not perform front-end inlining when
13823 the current context is itself an instance within a non-instance child
13824 unit, to prevent scope stack errors.
13825 (Save_References): If the node is an aggregate that is an actual in a
13826 call, rewrite as a qualified expression to preserve some type
13827 information, to resolve possible ambiguities in the instance.
13828 (Instance_Parent_Unit): New global variable to record the ultimate
13829 parent unit associated with a generic child unit instance (associated
13830 with the existing Parent_Unit_Visible flag).

13837 not already set. Replace test of Is_Child_Unit with test of parent's
13838 scope against package Standard. Add comments and a ??? comment.
13839 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible

13857 (Build_Private_Derived_Type): The entity of the created full view of the
13858 derived type does not come from source. If after installing the private
13859 declarations of the parent scope the parent is still private, use its
13860 full view to construct the full declaration of the derived type.
13861 (Build_Derived_Record_Type): Relax the condition that controls the
13862 execution of the check that verifies that the partial view and

13871 view is a transitive derivation of the ancestor of the partial view.
13872 (Process_Full_View): Rename local subprogram Find_Interface_In_
13873 Descendant to Find_Ancestor_Interface to leave the code more clear.
13874 Remove wrong code that avoids the generation of an error message
13875 when the immediate ancestor of the partial view is an interface.
13876 In addition some minor reorganization of the code has been done to
13877 leave it more clear.
13878 (Analyze_Type_Declaration): If type has previous incomplete tagged
13879 partial view, inherit properly its primitive operations.
13880 (Collect_Interfaces): Make public, for analysis of formal

13892 and derived protected types, the parent may be an interface that must
13893 be included in the interface list.
13894 (Access_Definition): If the designated type is an interface that may
13895 contain tasks, create Master_Id for it before analyzing the expression
13896 of the declaration, which may be an allocator.

13907 subprogram declaration.
13908 Change name Is_Package to Is_Package_Or_Generic_Package
13909 (Process_Formals): A non null qualifier on a non null named access
13910 type is not an error, and is a warning only if Redundant_Constructs

13921 package associated with a generic instance or formal package, the
13922 private declarations of the parent must be installed (by calling new

13924 Change name Is_Package to Is_Package_Or_Generic_Package
13925 (Preserve_Full_Attributes): For a synchronized type, the corresponding

13931 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
13932 not try to rewrite a renamed stream attribute, because the operations
13933 on the type may not have been generated.
13934 Handle properly a renaming_as_body generated for a stream operation
13935 whose default is abstract because the object type itself is abstract.
13936 (Find_Type): If the type is incomplete and appears as the prefix of a
13937 'Class reference, it is tagged, and its list of primitive operations
13938 must be initialized properly.
13939 (Chain_Use_Clauses): When chaining the use clauses that appear in the
13940 private declaration of a parent unit, prior to compiling the private
13941 part of a child unit, find on the scope stack the proper parent entity
13942 on which to link the use clause.
13943 (Note_Redundant_Use): Emit a warning when a redundant use clause is
13945 (Analyze_Object_Renaming): An attribute reference is not a legal object

13963 a procedure call is used as a select statement trigger and is not an
13964 entry renaming or a primitive of a limited interface.
13965 (Valid_Conversion): If the operand has a single interpretation do not
13966 remove address operations.
13967 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
13968 statement to inhibit warning.
13969 (Resolve_Unary_Op): Do not produce a warning when
13970 processing an expression of the form -(A mod B)
13971 Use Universal_Real instead of Long_Long_Float when we need a high
13972 precision float type for the generated code (prevents gratuitous
13973 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
13974 (Resolve_Concatenation_Arg): Improve error message when argument is an
13975 ambiguous call to a function that returns an array.
13976 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

14918 * checks.adb (Check_Needed): New procedure, deals with removing checks
14919 based on analysis of short-circuited forms. Also generates warnings for
14920 improper use of non-short-circuited forms.

14936 (Error_Msg_Warn): New variable for < insertion char.
14937 * prj-nmsc.adb: Implement new errout insertion char < (conditional
14939 (Check_For_Source): Change value of Source_Id only after the current
14940 source has been dealt with.
14942 2005-09-01 Robert Dewar <dewar@adacore.com>
14943 Doug Rupp <rupp@adacore.com>
14945 * exp_attr.adb: Handle vax fpt for 'Valid attribute

14951 Hristian Kirtchev <kirtchev@adacore.com>
14952 Javier Miranda <miranda@adacore.com>
14954 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
14955 from object notation, the original node is unanalyzed and carries no
14956 semantic information, so that accessiblity checks must be performed on
14957 the type of the actual itself.
14958 (Expand_N_Subprogram_Declaration): Change last actual parameter for
14959 compatibility with Build_Protected_Sub_Specification.
14960 (Check_Overriding_Inherited_Interfaces): Add suport to handle
14961 overloaded primitives.
14962 (Register_Interface_DT_Entry): Use the new name of the formal
14963 the the calls to Expand_Interface_Thunk
14965 * exp_dbug.ads: Augment comments on encoding of protected types to
14966 include the generation of dispatching subprograms when the type
14967 implements at least one interface.
14969 * lib.ads: Extend information in Load_Stack to include whether a given
14970 load comes from a Limited_With_Clause.
14972 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
14973 whether a potential circularity is harmless, because it includes units
14974 loaded through a limited_with clause. Extends previous treatment which
14975 did not handle properly arbitrary combinations of limited and
14976 non-limited clauses.
14978 2005-09-01 Nicolas Setton <setton@adacore.com>
14980 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
14981 to be encoded as typ___XBLU_lowerbound__upperbound instead of
14982 typ___XB_lowerbound__upperbound.
14984 2005-09-01 Thomas Quinot <quinot@adacore.com>
14986 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
14987 dummy access formal for RACW/RAS TypeCode TSS.
14988 (Build_TypeCode_Call): Do not generate dummy null access actual for
14989 calls to the TypeCode TSS.
14991 2005-09-01 Ed Schonberg <schonberg@adacore.com>
14993 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
14994 fully qualified name, to distinguish instances with the same local name.
14996 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
14999 2005-09-01 Robert Dewar <dewar@adacore.com>

15008 (Close): Deallocate any existing filter for the concerned connection
15010 2005-09-01 Laurent Pautet <pautet@adacore.com>
15012 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
15013 position set is provided, we compute one in order to reduce the maximum
15014 length of the keys. This computation first selects a character
15015 position between 1 and the minimum length of the keys in order to
15016 avoid reducing one of the keys to an empty string.
15017 (Initialize, Compute): When the ratio V to K is too low, the algorithm
15018 does not converge. The initialization procedure now comes with a
15019 maximum number of iterations such that when exceeded, an exception is
15020 raised in Compute. The user can initialize this ratio to another value
15022 Reformating and updated headers.
15024 2005-09-01 Javier Miranda <miranda@adacore.com>
15026 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
15027 that given an entity T creates and returns an Itype that duplicates the
15028 contents of T. The returned Itype has the null-exclusion
15029 attribute set to True, and its Etype attribute references T
15030 to keep the association between the two entities.
15031 Update copyright notice
15033 * sem_aggr.adb (Check_Can_Never_Be_Null,
15034 Aggregate_Constraint_Checks, Resolve_Aggregate,
15035 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
15037 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

15040 Robert Dewar <dewar@adacore.com>
15041 Hristian Kirtchev <kirtchev@adacore.com>

15049 (P_Subprogram_Specification): Add parsing of anonymous access result
15050 plus null exclusions. Call Set_Result_Definition instead of
15053 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
15054 (P_Access_Type_Definition): Add parsing for an anonymous access result
15055 subtype, plus parsing for null exclusions. Call Set_Result_Definition
15056 instead of Set_Subtype_Mark.
15058 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
15059 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
15060 (Result_Definition): New function for N_Function_Specifications.
15061 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
15062 N_Function_Specification.
15063 (Set_Null_Exclusion_Present): Allow this flag for
15064 N_Function_Specification.
15065 (Set_Result_Definition): New procedure for N_Function_Specifications.
15066 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
15067 and N_Function_Specification.
15069 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
15070 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
15071 Add support for LIMITED NEW for Ada 2005 AI-419
15072 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
15073 syntax for anonymous access results.
15074 Replace Subtype_Mark field by Result_Definition in
15075 N_Function_Specification and N_Access_Definition specs.
15076 Add Null_Exclusion_Present to spec of N_Function_Specification.
15077 (Result_Definition): New function for N_Function_Specification and
15078 N_Access_Function_Definition.
15079 (Set_Result_Definition): New procedure for N_Function_Specification and
15080 N_Access_Function_Definition.
15082 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
15083 Result_Definition for cases of N_Access_Function_Definition and
15084 N_Function_Specification.
15085 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
15087 2005-09-01 Vincent Celier <celier@adacore.com>
15089 * lib-writ.adb: Update Copyright notice
15090 (Write_With_Lines): On platforms where file names are case-insensitive,
15091 record the file names in lower case.
15092 (Write_ALI): For D lines, on platforms where file names are
15093 case-insensitive, record the file names in lower case.
15095 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15096 Emmanuel Briot <briot@adacore.com>
15098 * lib-xref.adb (Output_Overridden_Op): Display information on
15099 overridden operation.

15103 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
15106 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
15107 overriding entity information.
15109 2005-09-01 Vincent Celier <celier@adacore.com>
15111 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
15112 including those that are inherited.
15114 2005-09-01 Robert Dewar <dewar@adacore.com>
15116 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
15118 * par-prag.adb: Implement new pragma Debug_Policy
15120 * sem_prag.adb Implement new pragma Debug_Policy
15121 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
15122 Component_Size attribute specification. Give warning for ignored pragma
15125 * snames.h, snames.ads, snames.adb: Introduce entries in
15126 Preset_Names for Name_Disp_Asynchronous_Select,
15127 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
15128 Name_Disp_Timed_Select.
15129 New pragma Debug_Policy
15131 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
15133 Switch -gnata also sets Debug_Pragmas_Enabled
15135 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
15136 handle an explicit -gnata when compiling predefined files.
15138 2005-09-01 Vincent Celier <celier@adacore.com>
15140 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
15141 directories of projects that have no Ada sources.
15143 2005-09-01 Robert Dewar <dewar@adacore.com>
15145 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
15146 (makes a difference for wide characters)
15148 * widechar.adb, widechar.ads:
15149 Add Wide_Char_Byte_Count feature to count chars vs bytes
15151 2005-09-01 Thomas Quinot <quinot@adacore.com>
15152 Ed Schonberg <schonberg@adacore.com>
15153 Robert Dewar <dewar@adacore.com>
15155 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
15156 'Address attribute reference with an overloaded prefix, use the
15157 location of the prefix (not the location of the attribute reference) as
15158 the error location.
15159 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
15160 a function renaming thereof, is a valid prefix for 'Size (where it is
15161 intepreted as a function call).
15162 (Statically_Denotes_Entity): New predicate to determine whether the
15163 prefix of an array attribute can be considered static.
15166 (Eval_Attr): Fix failure to evaluate Component_Size for
15167 unconstrained arrays (resulted in wrong value in packed case, since
15168 back end cannot handle this case)
15170 2005-09-01 Robert Dewar <dewar@adacore.com>
15172 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
15173 error msgs for most common cases.
15174 Use new errout insertion char < (conditional warning)
15176 2005-09-01 Javier Miranda <miranda@adacore.com>
15177 Ed Schonberg <schonberg@adacore.com>
15179 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
15180 become local to the whole package.
15181 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
15182 the package was already analyzed the new algorithm "replaces" the
15183 real entities by the shadow ones. This is required to ensure that
15184 the order of these entities in the homonym chains does not change;
15185 otherwise we can have undefined references at linking time because
15186 in case of conflicts the external name of the entities will have
15187 a suffix that depends on the order of the entities in the chain.
15188 (Remove_Limited_With_Clause): Complementary code that completes the
15189 new algorithm and replaces the shadow entities by the real ones.
15190 (Install_Limited_Withed_Unit): When unchaining entities before the
15191 installation of the shadow entities, only regular entities of the
15192 public part must be taken into account. This is required to
15193 keep this routine in synch with the work done by Remove_Limited_
15195 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
15196 even if unit is analyzed, because the analysis of the unit is
15197 idempotent in any case, and the limited view of the unit may have to
15198 be installed for proper visibility.
15199 (Expand_Limited_With_Clause): Even if the unit in the implicit
15200 with_clause has been analyzed already, a limited view of the package
15201 must be built for the current context, if it does not exist yet.
15203 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15204 Javier Miranda <miranda@adacore.com>
15205 Gary Dismukes <dismukes@adacore.com>
15207 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
15208 defining entity for the instance body, make a new defining identifier
15209 rather than copying the entity of the spec, to prevent accidental
15210 sharing of the entity list.
15211 (Check_Private_View): When exchanging views of private types, build the
15212 list of exchanged views as a stack, to ensure that on exit the exchanges
15213 are undone in the proper order.
15214 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
15215 Restore the compilation environment in case of instantiation_error.
15216 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
15217 for an anonymous access result.
15218 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
15219 (Formal_Entity): Handle properly the case of a formal package that
15220 denotes a generic package renaming.
15222 2005-09-01 Thomas Quinot <quinot@adacore.com>
15224 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
15225 clause if the array aggregate is surrounded by parentheses.
15227 2005-09-01 Cyrille Comar <comar@adacore.com>
15228 Gary Dismukes <dismukes@adacore.com>
15229 Ed Schonberg <schonberg@adacore.com>
15230 Javier Miranda <miranda@adacore.com>
15232 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
15234 to check if a type is Constrained in cases related to code generation
15235 (rather than semantic checking) since otherwise we do not generate
15236 similar code for mutable private types depending if their
15237 discriminants are visible or not.
15238 (Check_Abstract_Overriding): Do not complain about failure to override
15239 the primitive operations used in dispatching selects since they will
15240 always be overriden at the freeze point of the type.
15241 (Access_Definition): Separate out handling for resetting the scope
15242 of an anonymous access function result type. Retrieve the scope
15243 of the associated function rather than using Current_Scope, which
15244 does not have a consistent value (depends on whether we're in the
15245 middle of analyzing formal parameters). Add ??? comment about
15246 finding a cleaner way to handle the special cases of scope setting.
15247 (Process_Incomplete_Dependents): A protected operation is never a
15248 dispatching operation (only its wrapper may be).
15249 (Build_Derived_Record_Type): In case of tagged private types that
15250 implement interfaces add derivation of predefined primitive
15252 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
15253 by two parameters that are used in case of derivation from abstract
15254 interface types: No_Predefined_Prims is used to avoid the derivation
15255 of predefined primitives from the interface, and Predefined
15256 Prims_Only is used to complete the derivation predefined primitives
15257 in case of private tagged types implementing interfaces.
15258 Fix typo in comments
15259 (Find_Interface_In_Descendant): Protect the frontend against
15260 wrong code with large circularity chains.
15261 (Is_Private_Overriding): Add support for entities overriding interface
15262 subprograms. The test failed because Entities associated with overriden
15263 interface subprograms are always marked as hidden (and used to build
15264 the secondary dispatch table); in this case the overriden entity is
15265 available through the field abstract_interface_alias (cf. override_
15266 dispatching_operation)
15267 (Access_Definition): Set the scope of the type to Current_Scope for the
15268 case of a function with an anonymous access result type.
15269 (Access_Subprogram_Declaration): Handle creation of the type entity for
15270 an access-to-function type with an anonymous access result.
15271 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
15272 in handling for N_Access_Function_Definition.
15273 (Analyze_Subtype_Declaration): Modify the text of error message.
15274 (Derived_Type_Declaration): Modify the text of error message.
15275 (Process_Subtype): Modify the text of error message plus cleanup
15276 of one redundant error message.
15277 (Analyze_Component_Declaration): Code cleanup.
15278 (Analyze_Object_Declaration): Code cleanup.
15279 (Analyze_Subtype_Declaration): Propagate the null-exclusion
15280 attribute in case of access types. Code cleanup.
15281 (Array_Type_Declaration): Code cleanup.
15282 (Process_Discriminants): Create the new null-excluding itype
15283 if required. Code cleanup.
15284 (Process_Subtype): Create the new null-excluding itype if
15285 required. Code cleanup.
15286 (Build_Derived_Record_Type): Code cleanup to avoid calling
15287 twice the subprogram derive_subprograms in case of private
15288 types that implement interfaces. In this particular case the
15289 subprogram Complete_Subprograms_Derivation already does the
15290 job associated with the second call.
15292 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
15293 conversion to the full view when generating an operation for a
15294 discriminant whose type may currently be private.
15296 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15297 Javier Miranda <miranda@adacore.com>
15299 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
15300 V (Obj.F), the rewriting does not involve the indexed component, but
15301 only the selected component itself.
15302 Do not apply the transformation if the analyzed node is an actual of a
15303 call to another subprogram.
15304 (Complete_Object_Operation): Retain the entity of the
15305 dispatching operation in the selector of the rewritten node. The
15306 entity will be used in the expansion of dispatching selects.
15307 (Analyze_One_Call): Improve location of the error message associated
15309 (Analyze_Selected_Component): No need to resolve prefix when it is a
15310 function call, resolution is done when parent node is resolved, as
15312 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
15313 when attempting to resolve a call transformed from its object notation.
15314 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
15315 of the argument list for each interpretation of the operation.
15316 (Try_Object_Operation): The designated type of an access parameter may
15317 be an incomplete type obtained through a limited_with clause, in which
15318 case the primitive operations of the type are retrieved from its full
15320 (Analyze_Call): If this is an indirect call, and the return type of the
15321 access_to_subprogram is incomplete, use its full view if available.
15323 2005-09-01 Javier Miranda <miranda@adacore.com>
15324 Gary Dismukes <dismukes@adacore.com>
15326 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
15327 access types the null-exclusion and access-to-constant attributes must
15329 (Analyze_Return_Statement): When the result type is an anonymous access
15330 type, apply a conversion of the return expression to the access type
15331 to ensure that appropriate accessibility checks are performed.
15332 (Analyze_Return_Type): For the case of an anonymous access result type,
15333 generate the Itype and set Is_Local_Anonymous_Access on the type.
15334 Add ??? placeholder for check to disallow returning a limited object
15335 in Ada 2005 unless it's an aggregate or a result of a function call.
15336 Change calls from Subtype_Mark to Result_Definition.
15337 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
15338 Result_Definition in call to Make_Function_Specification.
15339 (Build_Body_To_Inline): Change Set_Subtype_Mark to
15340 Set_Result_Definition.
15341 (Make_Inequality_Operator): Change formal Subtype_Mark to
15342 Result_Definition in call to Make_Function_Specification.
15343 (Process_Formals): Create the new null-excluding itype if required.
15344 (New_Overloaded_Entity): For an entity overriding an interface primitive
15345 check if the entity also covers other abstract subprograms in the same
15346 scope. This is required to handle the general case, that is, overriding
15347 other interface primitives and overriding abstract subprograms inherited
15348 from some abstract ancestor type.
15349 (New_Overloaded_Entity): For an overriding entity that comes from
15350 source, note the operation that it overrides.
15351 (Check_Conformance, Type_Conformant): Addition of one new formal
15352 to skip controlling formals in the analysis. This is used to
15353 handle overloading of abstract interfaces.
15354 (Base_Types_Match): Add missing case for types imported from
15355 limited-with clauses
15356 (New_Overloaded_Entity): Add barrier to protect the use of
15357 the "alias" attribute.
15359 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15361 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
15362 verify that the procedure and the entry are mode conformant.
15363 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
15364 as a different operator, which is often a cut-and-paste error.
15366 2005-09-01 Javier Miranda <miranda@adacore.com>
15367 Ed Schonberg <schonberg@adacore.com>
15369 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
15370 used in controlling parameters exclude null because it is necessary to
15371 read the tag to dispatch, and null has no tag.
15372 (Override_Dispatching_Operation): If the previous operation is inherited
15373 from an interface, it becomes hidden and does not participate in later

15377 Ed Schonberg <schonberg@adacore.com>
15378 Gary Dismukes <dismukes@adacore.com>
15380 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
15381 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
15382 the expander will generate the corresponding run-time check to evaluate
15384 (Resolve_Call): Check for legal type of procedure name or prefix that
15385 appears as a trigger in a triggering alternative.
15386 (Valid_Conversion): If expression is ambiguous and the context involves
15387 an extension of System, remove System.Address interpretations.
15388 (Resolve_Qualified_Expression): Reject the case of a specific-type
15389 qualification applied to a class-wide argument. Enhance comment
15390 to explain checking of Original_Node.
15391 (Resolve_Type_Conversion): The location of the error message was not
15392 general enough to handle the general case and hence it has been removed.
15393 In addition, this patch improves the text of the message.
15394 (Resolve_Type_Conversion): Add missing support for access to interface
15396 (Resolve_Type_Conversion): If the target is a class-wide interface type,
15397 do not expand if the expression is the actual in a call, because proper
15398 expansion will take place when the call itself is expanded.
15399 (Resolve_Allocator): If the context is an unchecked conversion, the
15400 allocator inherits its storage pool, if any, from the target type of

15404 Javier Miranda <miranda@adacore.com>
15406 * sem_type.adb (Add_One_Interp): If a candidate operation is an
15407 inherited interface operation that has an implementation, use the
15408 implementation to avoid spurious ambiguities.
15409 (Interface_Present_In_Ancestor): In case of concurrent types we can't
15410 use the Corresponding_Record_Typ attribute to look for the interface
15411 because it is set by the expander (and hence it is not always
15412 available). For this reason we traverse the list of interfaces
15413 (available in the parent of the concurrent type).
15414 (Interface_Present_In_Ancestor): Handle entities from the limited view
15416 2005-09-01 Ed Schonberg <schonberg@adacore.com>

15421 primitive procedure of a limited interface with a controlling first
15423 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
15425 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
15426 capture if it is generated in the second operand of a short-circuit
15428 Do not capture values for variables with address clauses.
15429 (Is_Object_Reference): Treat a function call as an object reference only
15430 if its type is not Standard_Void_Type.
15432 2005-09-01 Ed Schonberg <schonberg@adacore.com>
15434 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied

16217 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
16218 longer protected objects. They have been replaced by lower-level
16219 suspension objects made up by a mutex and a condition variable (or
16220 their equivalent given a particular OS) plus some internal data to
16221 reflect the state of the suspension object.
16222 (Initialize, Finalize): Add this initialization procedure for
16223 Suspension_Object, which is a controlled type.
16224 (Finalize): Add the finalization procedure for Suspension_Object,
16225 which is a controlled type.
16227 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

16250 object to True, releasing the task that was suspended, if any.
16251 (Suspend_Until_True): Add this procedure that blocks the calling task
16252 until the state of the object is True. Program_Error is raised if
16253 another task is already waiting on that suspension object.
16254 (Initialize): Add this procedure for initializing the suspension
16255 object. It initializes the mutex and the condition variable which are
16256 used for synchronization and queuing, and it sets the internal state
16258 (Finalize): Add this procedure for finalizing the suspension object,
16259 destroying the mutex and the condition variable.

16265 which provides a low-level abstraction (using operating system
16266 primitives) for Ada.Synchronous_Task_Control.
16267 This object is made up by a mutex (for ensuring mutual exclusion), a
16268 condition variable (for queuing threads until the condition is
16269 signaled), a Boolean (State) indicating whether the object is open,
16270 and a Boolean (Waiting) reflecting whether there is a task already

16479 same functionality and it is more clear in case of primitives
16480 associated with abstract interfaces.
16481 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
16482 clean up, the functionality of this subprogram is now provided
16483 by Set_All_DT_Position.

16485 within gdb to display the dispatch tables associated with a tagged
16487 (Collect_All_Interfaces): New subprogram that collects the whole list
16488 of interfaces that are directly or indirectly implemented by a tagged
16490 (Default_Prim_Op_Position): New subprogram that returns the fixed
16491 position in the dispatch table of the default primitive operations.
16492 (Expand_Interface_Actuals): New subprogram to generate code that
16493 displaces all the actuals corresponding to class-wide interfaces to
16494 reference the interface tag of the actual object.
16495 (Expand_Interface_Conversion): New subprogram. Reference the base of
16496 the object to give access to the interface tag associated with the
16497 secondary dispatch table.
16498 (Expand_Interface_Thunk): New subprogram that generates the code of the
16499 thunk. This is required for compatibility with the C+ ABI.
16500 (Make_Abstract_Interface_DT): New subprogram that generate the
16501 declarations for the secondary dispatch tables associated with an
16502 abstract interface.
16503 (Set_All_Interfaces_DTC_Entity): New subprogram that sets the DTC_Entity
16504 attribute for each primitive operation covering interface subprograms

16519 incorrectly setting the scope of an anonymous access component's type.
16520 (Process_Discriminants): Set Is_Local_Anonymous_Access for the type of
16521 an access discriminant when the containing type is nonlimited.
16522 (Make_Incomplete_Type_Declaration): Create an incomplete type
16523 declaration for a record type that includes self-referential access
16525 (Check_Anonymous_Access_Types): Before full analysis of a record type
16526 declaration, create anonymous access types for each self-referential
16528 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
16529 an access component in this context is a Local_Anonymous_Access, for
16530 proper accessibility checks.
16531 (Access_Definition): Set properly the scope of the anonymous access type
16532 created for a stand-alone access object.
16533 (Find_Type_Of_Object): An object declaration may be given with an access
16535 (Complete_Subprograms_Derivation): New subprogram used to complete
16536 type derivation of private tagged types implementing interfaces.
16537 In this case some interface primitives may have been overriden

16673 (Analyze_Subprogram_Body): Undo the previous work.
16674 (Analyze_Procedure_Call): If the call has the form Object.Op, the

16678 subprogram_specification that returns true if some non
16679 class-wide interface subprogram is found

16683 access to subprograms must be recursive.
16684 (Is_Unchecked_Conversion): Improve the test that recognizes
16685 instantiations of Unchecked_Conversion, and allows them in bodies that
16686 are to be inlined by the front-end. When the body comes from an

16710 Prevent the special checks for conversions of access discriminants in
16711 the case where the discriminant belongs to a nonlimited type, since
16712 such discriminants have their accessibility level defined in the same
16713 way as a normal component of an anonymous access type.
16714 (Resolve_Allocator): When an allocator's designated type is a class-wide
16715 type, check that the accessibility level of type given in the
16716 allocator's expression or subtype indication is not statically deeper

16736 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
16737 check on possible violation of restriction No_Direct_Boolean_Operators
16738 until after expansion of operands, to prevent spurious errors when

17041 the "simple_choice" member in a variant record, in accordance with the
17042 description in the package spec: the information output for a constant
17043 should be "S number", not "SS number".
17044 (Get_Encoded_Name): Return at once if not generating code. Avoids name

17132 unit as a consequence of parsing a limited-with clause. This is used
17133 to avoid the circularity check.

17139 againts previously reported critical errors in context clauses
17140 (Install_Limited_Withed_Unit): Code cleanup plus static detection
17141 of two further errors: renamed subprograms and renamed packages

17695 (check dos line terminator).
17696 (Check_Line_Max_Length): New procedure, split off from the existing
17697 Check_Line_Terminator routine. Separating this out allows -gnatyf to
17698 be properly recognized.
17700 * styleg.adb: Add ??? comment for line terminator reference

17743 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
17744 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
17745 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
17746 analyzed if expansion is disabled (which could otherwise cause spurious
17747 error messages if expansion has been disabled due to previous
17748 (unrelated) errors).
17750 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
17751 is disabled, the entity denoted by the argument is the access type
17752 itself, not an underlying record type, so there is no need to go back
17753 to the Corresponding_Remote_Type.
17755 2005-03-29 Gary Dismukes <dismukes@adacore.com>
17756 Robert Dewar <dewar@adacore.com>
17758 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
17759 expand a call to an instance of
17760 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
17761 Constructor actual of the instance. A class-wide membership
17762 check is also generated, to ensure that the tag passed to the instance
17763 denotes a type in the class.
17764 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
17765 of Name_Generic_Dispatching_Constructor.
17767 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
17768 05 unit for AI-260-02).

17780 character type cases.
17781 (Analyze_Subprogram_Renaming): Add special handling for
17782 the case of renaming of stream attributes when the renaming denotes a
17783 generic formal subprogram association for an abstract formal subprogram.
17784 Check that the attribute is a primitive stream attribute (and not
17785 a class-wide stream attribute) and then rewrite the attribute name
17786 as the name of the appropriate compiler-generated stream primitive.
17788 2005-03-29 Robert Dewar <dewar@adacore.com>
17790 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

17793 resulted in inaccurate result for unaligned scalars within records.
17795 2005-03-29 Ed Schonberg <schonberg@adacore.com>
17797 * freeze.adb (Freeze_Record_Type): If the type of the component is an
17798 itype whose parent is controlled and not yet frozen, do not create a
17799 freeze node for the itype if expansion is disabled.
17801 2005-03-29 Vincent Celier <celier@adacore.com>
17803 * make.adb (Gnatmake): Don't fail if the main project file is declared
17804 as having no Ada sources. Do not display message "no sources to
17805 compile" in quiet output.
17807 2005-03-29 Doug Rupp <rupp@adacore.com>
17809 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

17820 missing TYPE Improve the error message generated when compiling a
17821 limited interface in Ada83 or Ada95 mode.
17823 2005-03-29 Robert Dewar <dewar@adacore.com>
17825 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
17826 rather than proceed ahead using a junk attribute name.
17828 2005-03-29 Vincent Celier <celier@adacore.com>
17830 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
17832 * prj-part.adb (Parse_Single_Project): Set the location of a project
17833 on its defining identifier, rather than on the reserved word "project".
17835 * prj-proc.adb (Expression): Adapt to the fact that default of external
17836 references may be string expressions, not always literal strings.
17837 (Recursive_Process): Set Display_Name equal to Name
17838 when Location is No_Location, that is when there is no actual file.
17839 Get the Display_Name of the project from the source, when it is not a
17841 (Process): Use the Display_Name in error messages
17843 * prj-strt.adb (External_Reference): Allow default to be string
17844 expressions, not only literal strings.
17846 2005-03-29 Vincent Celier <celier@adacore.com>
17848 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
17849 file and the reference symbol file to be the same file.

17853 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
17854 forbid conversion of a local access-to-subprogram type to a remote one.
17856 * sem_util.adb (Wrong_Type): For a record type that is the expanded
17857 equivalent type for a remote access-to-subprogram type, go back to the
17858 original RAS entity when displaying an error message, so the casing is
17859 the original source casing.
17861 2005-03-29 Robert Dewar <dewar@adacore.com>
17863 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
17866 2005-03-29 Ed Schonberg <schonberg@adacore.com>
17868 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
17869 subtype if code is being pre-analyzed, to prevent un-expanded
17870 references to protected formals, among others.
17871 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
17872 interpretation that can be a call, include the result of the call as a
17873 possible interpretation of the dereference.
17875 * sem_ch5.adb (Process_Bounds): Determine type of range by
17876 pre-analyzing a copy of the original range, and then analyze the range
17877 with the expected type.
17879 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
17880 with an overloaded prefix where not all interpretations yield an
17881 access to subprogram, do not rewrite node as a call.
17882 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
17883 the node as a call once the context identifies the interpretation of
17884 the prefix whose call yields the context type.
17885 (Valid_Conversion): For the case of a conversion between
17886 local access-to-subprogram types, check subtype conformance using
17887 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
17888 detailed error message.
17890 2005-03-29 Ed Schonberg <schonberg@adacore.com>
17892 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
17893 indicator, indicate that the formal can never be null.
17894 (Process_Formals): If a formal has a non_null indicator, insert the
17895 resulting subtype immediately before the enclosing subprogram decl,
17896 and not at the beginning of the corresponding declarative part, to
17897 prevent access before elaboration (Ada2005).
17899 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
17902 * utils.c (finish_record_type): Use variable_size when setting sizes.

18443 * a-retide.ads: Minor comment changes
18445 2005-03-15 Robert Dewar <dewar@adacore.com>
18447 * a-stzunb.adb, a-stzunb.adb a-stzunb.ads, a-stzunb.ads,
18448 a-stwiun.ads, a-stwiun.adb, a-strunb.ads, a-strunb.adb: Move
18449 Realloc_For_Chunk to private part of package.
18450 New subprograms for AI-301
18452 * a-szuzti.adb, a-suteio.adb, a-swuwti.adb: Improve efficiency of
18453 Get_Line procedure.
18454 Avoid unnecessary use of Get/Set_Wide_String
18456 2005-03-15 Robert Dewar <dewar@adacore.com>
18459 * a-stunau.ads, a-stunau.adb:
18460 Change interface to allow efficient (and correct) implementation
18461 The previous changes to allow extra space in unbounded strings had
18462 left this interface a bit broken.
18464 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
18466 * g-spipat.ads, g-spipat.adb: New interface for Get_String
18467 Minor reformatting (function specs)
18469 * g-spitbo.adb: New interface for Get_String
18471 * g-spitbo.ads: Minor reformatting
18473 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
18475 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String

18479 Thomas Quinot <quinot@adacore.com>
18480 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
18482 * atree.ads, atree.adb: Add support for Elist24 field
18484 * atree.h: Fix wrong definition of Field27
18485 Add support for Elist16 field
18486 Add support for Elist24 field
18488 * einfo.ads, einfo.adb (Abstract_Interfaces,
18489 Set_Abstract_Interfaces): New subprograms.
18490 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
18492 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of

18501 (Set_Task_Body_Procedure): New subprogram to set this attribute.
18502 (Has_Controlled_Component): Now applies to all entities.
18503 This is only a documentation change, since it always worked to apply
18504 this to other than composite types (yielding false), but now this is
18506 Update documentation on Must_Be_Byte_Aligned for new spec
18508 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
18509 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
18510 uses of the Access_Disp_Table attribute to reference the first dispatch
18511 table associated with a tagged type. As
18512 part of the implementation of abstract interface types,
18513 Access_Disp_Table has been redefined to contain a list of dispatch
18514 tables (rather than a single dispatch table).
18515 Similarly, upgrade all the references to Tag_Component by the
18516 new attribute First_Tag_Component.
18517 (Find_Inherited_TSS): Moved to exp_tss.
18518 Clean up test in Expand_N_Object_Declaration for cases
18519 where we need to do a separate assignment of the initial value.
18520 (Expand_N_Object_Declaration): If the expression in the
18521 declaration of a tagged type is an aggregate, no need to generate an
18522 additional tag assignment.
18523 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
18525 Bit packed array ops are only called if operands are known to be
18527 (Component_Equality): When returning an N_Raise_Program_Error statement,
18528 ensure that its Etype is set to Empty to avoid confusing GIGI (which
18529 expects that only expressions have a bona fide type).
18530 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
18531 determine the amount of data to be copied.
18533 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
18534 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
18535 INTERFACE_TYPE_DEFINITION ::=
18536 [limited | task | protected | synchronized] interface
18537 [AND interface_list]
18539 * par-ch3.adb (P_Type_Declaration): Modified to give support to
18541 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
18543 (P_Interface_Type_Definition): New subprogram that parses the new
18544 syntax rule of Ada 2005 interfaces
18545 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
18546 messages by the correct RENAMES (quotes removed).
18548 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
18549 attribute First_Tag_Component.
18551 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
18552 (Interface_List, Set_Interface_List): New subprograms.
18553 (Interface_Present, Set_Interface_Present): New subprograms.
18554 (Limited_Present, Set_Limited_Present): Available also in derived
18555 type definition nodes.
18556 (Protected_Present, Set_Protected_Present): Available also in
18557 record type definition and
18558 derived type definition nodes.
18559 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
18560 (Task_Present, Set_Task_Present): New subprogram.
18561 (Task_Body_Procedure): Removed.
18562 (Set_Task_Body_Procedure): Removed.
18563 These subprogram have been removed because the attribute
18564 Task_Body_Procedure has been moved to the corresponding task type
18565 or task subtype entity to leave a field free to store the list
18566 of interfaces implemented by a task (for AI-345)
18567 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
18568 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
18569 expression flag Do_Range_Check
18570 (Exception_Junk): Change to Flag7 to accomodate above change
18571 (Box_Present, Default_Name, Specification, Set_Box_Present,
18572 Set_Default_Name, Set_Specification): Expand the expression
18573 "X in N_Formal_Subprogram_Declaration" into the corresponding
18574 two comparisons. Required to use the csinfo tool.
18576 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
18577 "with string" given.
18579 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
18582 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
18585 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
18586 attribute Task_Body_Procedure rather than the old semantic field that
18587 was available in the task_type_declaration node.
18589 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
18590 interface type definitions.
18591 (P_Formal_Derived_Type_Definition): Modified to handle the list of
18594 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
18595 task type declaration.
18596 (P_Protected): Modified to handle the list of interfaces in a
18597 protected type declaration.
18599 2005-03-15 Doug Rupp <rupp@adacore.com>
18600 Vincent Celier <celier@adacore.com>
18602 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
18603 (Gen_Output_File_C): Likewise.
18604 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
18606 2005-03-15 Thomas Quinot <quinot@adacore.com>
18608 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
18609 is an N_Raise_Constraint_Error node, create a new copy of it without
18610 going through a call to Duplicate_Subexpr.
18612 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
18613 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
18614 Nicolas Setton <setton@adacore.com>
18615 Ed Schonberg <schonberg@adacore.com>
18621 * decl.c (gnat_to_gnu_field): Reject aliased components with a
18622 representation clause that prescribes a size not equal to the rounded
18623 size of their types.
18624 (gnat_to_gnu_entity, case E_Component): Always look at
18625 Original_Record_Component if Present and not the entity.
18626 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
18627 of tagged extension types by not making field for components that are
18629 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
18630 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
18631 expression to the type of the object when the object is constant.
18632 Reverse defer_debug_incomplete_list before traversing it, so that trees
18633 are processed in the order at which they were added to the list. This
18634 order is important when using the stabs debug format.
18635 If we are deferring the output of debug information, also defer this
18636 output for a function return type.
18637 When adding fields to a record, prevent emitting debug information
18638 for incomplete records, emit the information only when the record is
18640 (components_to_record): New parameter defer_debug.
18641 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
18642 (gnat_to_gnu_field_decl): New function.
18643 (substitution_list, annotate_rep): Call it.
18644 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
18645 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
18646 No longer update discriminants to not be a COMPONENT_REF.
18647 (copy_alias_set): Strip padding from input type; also handle
18648 unconstrained arrays properly.
18650 * gigi.h (write_record_type_debug_info): New function.
18651 Convert to use ANSI-style prototypes. Remove unused
18652 declarations for emit_stack_check, elab_all_gnat and
18653 set_second_error_entity.
18654 (gnat_to_gnu_field_decl): New decl.
18656 * utils.c (write_record_type_debug_info): New function.

18660 (update_pointer_to): Fix pasto.
18661 (convert) <UNION_TYPE>: Accept slight type variations when
18662 converting to an unchecked union type.
18664 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
18665 replace the N_Freeze_Entity with a null statement.
18667 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
18668 within a constrained subcomponent of an enclosing record, place the
18669 freeze nodes in the scope stack entry for the enclosing record.
18670 (Undelay_Type): New Subprogram.
18671 (Set_Small_Size): Pass T, the type to modify; all callers changed.
18672 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
18673 within records; allow them to have freeze nodes if their base types
18676 * exp_util.adb (Remove_Side_Effects): Properly test for
18677 Expansion_Delayed and handle case when it's inside an
18678 N_Qualified_Expression.
18680 * sem_ch3.adb (Derived_Type_Declaration): New predicate
18681 Comes_From_Generic, to recognize accurately that the parent type in a
18682 derived type declaration can be traced back to a formal type, because
18683 it is one or is derived from one, or because its completion is derived
18685 (Constrain_Component_Type): If component comes from source and has no
18686 explicit constraint, no need to constrain in in a subtype of the
18688 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
18689 Minor change to propagate Is_Ada_2005 flag
18691 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
18692 Expansion_Delayed is False.
18693 (assoc_to_constructor): Ignore fields that have a
18694 Corresponding_Discriminant.
18695 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
18696 function returns "by target", dereference the target pointer using the
18697 type of the actual return value.
18698 <all>: Be prepared for a null gnu_result.
18699 (processed_inline_subprograms): Check flag_really_no_inline
18700 instead of flag_no_inline.
18701 (set_second_error_entity): Remove unused function.

18706 2005-03-15 Robert Dewar <dewar@adacore.com>
18707 Ed Schonberg <schonberg@adacore.com>
18708 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
18710 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
18711 Must_Be_Byte_Aligned for cases where we do not need to use a
18712 System.Pack_nn unit.
18714 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
18716 Needed now that we do some processing for IN parameters as well. This
18717 may well fix some unrelated errors.
18718 (Expand_Call): Handle case of unaligned objects (in particular those
18719 that come from packed arrays).
18720 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
18721 renamed entity is an inherited operation, re-expand the call using the
18722 original operation, which is the one to call.
18723 Detect attempt to inline parameterless recursive subprogram.
18724 (Represented_As_Scalar): Fix to work properly with private types
18725 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
18726 accurate estimate. Yields True in far fewer cases than before,
18727 improving the quality of code that depends on this test.
18729 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
18730 over both visible and private declarations to remove them from tree,
18731 and mark subprograms declared in package as eliminated, to prevent
18732 spurious use in subsequent compilation of generic units in the context.
18734 * exp_util.ads: Minor cleanup in variable names
18736 * sem_eval.ads, sem_eval.adb: Minor reformatting
18737 (Compile_Time_Known_Bounds): New function
18739 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18741 * exp_ch7.adb (Convert_View): Use base types of underlying types when
18742 determining whether an unchecked conversion is needed for the argument
18743 of an initialization call.
18745 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18747 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
18748 that appears in the instantiation rather than the internal subtype
18749 generated in the wrapper package, to avoid anomalies in gigi when the
18750 target is derived from a private type whose full view is an access type.
18752 2005-03-15 Robert Dewar <dewar@adacore.com>
18754 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
18756 Add documentation to replace the use of this flag
18757 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
18760 2005-03-15 Thomas Quinot <quinot@adacore.com>
18762 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
18763 here from exp_attr so it can be shared between exp_attr and exp_dist.
18764 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
18765 all TSS names, not a subset thereof, and the previous name introduced
18766 an unnecessarily confusion that a distinction might exist between
18767 "OK" TSS names and some "not OK" TSS names.
18769 2005-03-15 Doug Rupp <rupp@adacore.com>
18771 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
18774 2005-03-15 Pascal Obry <obry@adacore.com>
18775 Eric Botcazou <ebotcazou@adacore.com>
18779 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
18780 when IN_RTS. This is to work around a bootstrap path problem.
18782 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
18783 table and pass it to __gnat_install_SEH_handler().
18784 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
18786 * lang.opt: Fix specification of -fRTS=.
18788 2005-03-15 Doug Rupp <rupp@adacore.com>
18789 Bernard Banner <banner@adacore.com>
18790 Vincent Celier <celier@adacore.com>
18791 Arnaud Charlet <charlet@adacore.com>
18794 This change works fine when gnatlib is built from the gcc directory,
18795 but does not work when using the libada Makefile, since GCC_FOR_TARGET
18796 is not passed to ada/Makefile.in, so more work is needed by a
18797 Makefile/configure expert.
18799 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
18800 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
18801 Setup gnatlink switch -M for x86_64 linux, as it is already setup
18803 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
18804 Run ranlib on libgccprefix.a
18805 Define PREFIX_OBJS for Darwin, to build libgccprefix.
18806 (ADA_INCLUDE_SRCS): Split Ada packages.
18808 2005-03-15 Robert Dewar <dewar@adacore.com>
18810 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
18812 * impunit.adb: Add GNAT.UTF_32
18814 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
18816 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
18817 now uses GNAT.UTF_32).
18819 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
18820 capabilities for categorizing characters using Unicode categories
18822 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18824 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
18825 instantiation that has been rewritten as a package body, retrieve spec
18826 to generate proper name for implicit_with_clause.
18827 (Install_Parents): Recognize a parent that is an instantiation but has
18828 been rewritten as a package declaration during analysis.
18830 2005-03-15 Javier Miranda <miranda@adacore.com>
18831 Ed Schonberg <schonberg@adacore.com>
18833 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
18834 parameter reported some error we immediately return. This improves the
18835 behaviour of the frontend in case of errors.
18836 (Install_Parent, Remove_Parent): Introduce new flag
18837 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
18838 ancestor of a generic child unit, when the child is being instantiated.
18839 (Inline_Instance_Body): If we are compiling the private
18840 part or the body of a child unit, restore the proper visibility of the
18841 parents after compiling the instance body.
18843 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18844 Javier Miranda <miranda@adacore.com>
18847 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
18848 of a private type, in which case it is underlying_type that denotes
18849 the proper task. Also modified to use the new entity attribute
18850 that is directly available in the task type and task subtype entities
18851 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
18852 arrays when other dimensions than the first are constrained by
18853 discriminants of an enclosing record.
18854 (Insert_Explicit_Dereference): If the prefix is an indexed component or
18855 a combination of indexed and selected components, find ultimate entity
18856 and generate the appropriate reference for it, to suppress spurious
18858 (Note_Possible_Modification): If an entity name has no entity, return.
18859 (Is_Variable): A function call never denotes a variable.
18860 (Requires_Transient_Scope): For record types, recurse only on
18861 components, not on internal subtypes that may have been generated for
18862 constrained components.
18864 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18866 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
18867 Eliminated as candidates for resolution. Both efficient, and avoids
18868 anomalies with operators declared in deleted code.
18869 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
18870 expansion is disabled (as when compiling a generic) to prevent spurious
18871 warnings on prefixes of selected components.
18873 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18875 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
18876 attached to a list before checking whether it appears in the private
18877 declarations of the current package.
18878 (Make_Inequality_Operator): Insert declaration in proper declarative
18879 list rather than just setting the Parent field, so that
18880 Is_Private_Declaration can handle it properly.
18882 2005-03-15 Ed Schonberg <schonberg@adacore.com>
18884 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
18885 a renaming a body, check that the renamed subprogram in not intrinsic.
18886 (Find_Direct_Name): If several use_visible entities hide
18887 each other, and the context is a predefined file compiled through
18888 rtsfind, keep only the entity that comes from a predefined file.
18890 2005-03-15 Geert Bosch <bosch@adacore.com>
18892 * s-fatgen.adb (Valid): Extend special exceptions to account for long
18893 long float padding to also cover AMD64 and IA64.
18895 2005-03-15 Gary Dismukes <dismukes@adacore.com>
18897 * s-imgwch.adb: Add with and use of Interfaces.
18898 (Img_Wide_Character): Change type of Val to Unsigned_16.
18899 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
18901 2005-03-15 Matthew Gingell <gingell@adacore.com>
18903 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
18905 2005-03-15 Robert Dewar <dewar@adacore.com>
18907 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
18909 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
18911 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
18913 2005-03-15 Robert Dewar <dewar@adacore.com>
18915 * s-bitops.adb, s-bitops.ads,

19375 the formal subprogram.
19376 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
19377 which is an unclean use of that field, we set the new field

19393 analysis of the name rewrites the node and analyzes it with the proper
19394 argument list. After analyzing the name, if the call has been rewritten
19395 and the result type is set, no further analysis is needed.
19396 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
19397 mark in function specification, in a context where the formals are
19398 visible and hide outer homographs.

19404 procedure", covering the case of a call to a formal abstract procedure
19405 that has statically tagged operands.
19406 (Check_Dispatching_Call): Check for the case of an actual given by
19407 a tag-indeterminate function call whose type is an ancestor of the
19408 containing call's associated tagged type. This situation can occur
19409 for inherited primitives with function defaults. In this case we
19410 use the tagged type's tag directly as the controlling argument for
19412 (Expand_Call): Name change on call to Expand_Dispatch_Call.
19414 * sprint.adb (Sprint_Node_Actual): Split
19415 N_Formal_Subprogram_Declaration into two alternatives for the new

19477 GNAT.OS_Lib.Set_Close_On_Exec.
19479 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
19480 the parent side as close-on-exec so that they are not inherited by the

19486 2005-02-09 Eric Botcazou <ebotcazou@adacore.com>
19487 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
19491 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
19492 on the field if Pragma Component_Alignment (Storage_Unit).
19493 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
19494 side-effects as if it were a constant; also make SAVE_EXPR to protect
19496 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a

19512 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19514 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
19515 component of an array of arrays in an assignment context, and the
19516 aggregate has component associations that require sliding on
19517 assignment, force reanalysis of the aggregate to generate a temporary
19518 before the assignment.
19519 (Must_Slide): Make global to the package, for use in Gen_Assign.
19521 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19523 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
19524 unchecked union with no inferable discriminants, return a
19525 Raise_Program_Error node, rather than inserting it at the point the
19527 (Expand_Record_Equality, Component_Equality): Handle properly the case
19528 where some subcomponent is an unchecked union whose generated equality
19529 code raises program error.

19537 Arnaud Charlet <charlet@adacore.com>
19539 * init.c (__gnat_initialize): Add a new parameter eh which contains the
19540 address of the exception registration. The Win32 version of this
19541 routine calls __gnat_install_SEH_handler() to initialize the SEH
19542 (Structured Exception Handling) handler.
19543 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
19544 SEH (Structured Exception Handling) now.
19545 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
19546 (__gnat_initialize for ppc-vxworks): Adjust comments and the
19547 preprocessor condition protecting the call to the extra eh setup
19548 subprogram, which is only available for the ppc target.
19549 (__gnat_clear_exception_count): replaced reference to
19550 variable taskIdCurrent by call to taskIdSelf(), cleaner.
19552 * seh_init.c: New file.

19555 (GNATBIND_OBJS): Idem.
19557 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
19558 routine takes a new parameter (a pointer to the exception registration
19559 for the SEH (Structured Exception Handling) support.
19561 * raise.h: (__gnat_install_SEH_handler): New prototype.
19562 Update copyright notice.
19564 * s-tassta.adb (Task_Wrapper): Declare the exception registration
19565 record and initialize it by calling __gnat_install_SEH_handler.

19594 2005-02-09 Vincent Celier <celier@adacore.com>
19596 * prj-makr.adb (Process_Directory): Put file name in canonical case
19597 before matching against the patterns.
19598 If gnatname has been invoked as <prefix>-gnatname
19599 then invoke the compiler as <prefix>-gcc, not just "gcc".
19601 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19603 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
19604 with expansion disabled. The actual subtype is needed among other
19605 places when the selected component appears in the context of a loop
19606 bound, and denotes a packed array.
19607 (Operator_Check): Always use the first subtype in the
19608 error message, to avoid the appearance of internal base types.
19609 (Transform_Object_Operation): Copy each actual in full
19610 to the parameter associations of the constructed call, rather than
19611 using the shallow copy mechanism of New_Copy_List. This ensures that
19612 the chaining of named associations is done properly.
19613 (Complete_Object_Operation): Rewrite node, rather than
19614 replacing it, so that we can trace back to the original selected
19617 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
19618 and calls that use object notation, if the called function is not
19619 declared in a withed unit, place the elaboration constraint on the
19620 unit in the context that makes the function accessible.
19621 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
19622 imposes an elaboration constraint between two packages.
19624 2005-02-09 Ed Schonberg <schonberg@adacore.com>
19626 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
19627 views of a private type after handling its private dependents, to
19628 maintain proper stack discipline between entry and exit from the

19649 Slight fix to documentation of -gnaty with no parameters
19651 * xr_tabls.ads: Add ??? comment for missing overall comment
19653 * xsinfo.adb: Make default file name be sinfo.h, since this is what
19654 we now use by default.
19656 * xsnames.adb: Adjust end of file test to look for five space followed
19657 by '#' instead of six spaces. The format of xsnames.adb was modified
19658 in the last update.
19660 * a-numeri.ads: Add reference to AI-388 for greek letter pi
19663 * clean.adb: Minor reformatting.
19665 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

19667 Add 2005 to copyright output when utility is run
19669 * csets.adb: Eliminate obsolete comment
19671 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
19674 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
19676 2005-02-09 Sergey Rybin <rybin@adacore.com>
19678 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
19679 the difference between compact and incompact layout and add the record
19680 representation clause to the example illustrating different layouts.
19681 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
19682 component clauses").
19684 2005-02-09 Florian Villoing <villoing@adacore.com>
19686 * gnat_ugn.texi: Fix typos.
19687 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
19689 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
19690 in the generated documentation.

19734 * exp_util.ads: Minor correction in comment.
19736 2005-02-09 Arnaud Charlet <charlet@adacore.com>
19738 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
19739 since this procedure is now too complex to be worth inlining.

20373 flag. No longer needed now that we handle this in gnat1drv.adb.
20375 * repinfo.ads: Minor reformatting
20377 2004-12-07 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
20378 Olivier Hainque <hainque@adacore.com>
20379 Eric Botcazou <ebotcazou@adacore.com>
20381 * decl.c (maybe_pad_type): Use TYPE_SIZE_UNIT of the input type for
20382 TYPE_SIZE_UNIT of result type if SIZE is not specified.
20383 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
20384 of a bitfield, which we know is useless and causes trouble because of
20385 alignment implications.
20387 * utils.c (create_var_decl): Set DECL_COMMON again on targets without
20389 (process_attributes): Clear DECL_COMMON again when a section attribute
20391 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
20392 SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
20393 (create_field_decl): Special case ADDRESSABLE negative to mean
20394 "no bitfield creation", to be used by make_aligning_type. Don't
20395 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
20396 fields claimed addressable still have to be bitfields. Use
20397 value_factor_p instead of a raw binop construction to check for the
20398 position's alignment.
20400 2004-12-07 Geert Bosch <bosch@adacore.com>
20402 * eval_fat.adb: Revert previous change.
20404 2004-12-07 Thomas Quinot <quinot@adacore.com>
20405 Ed Schonberg <schonberg@adacore.com>
20407 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
20408 with an implicit dereference as its prefix, use
20409 Insert_Explicit_Dereference instead of merely rewriting the prefix into
20410 an explicit dereference. This ensures that a reference to the original
20411 prefix is generated, if appropriate.
20413 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
20414 dereference is rewritten to an explicit one, generate a reference to
20415 the entity denoted by its prefix using the original prefix node, so
20416 the dereference can be properly recorded as a read of the denoted
20417 access value, if appropriate.
20419 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
20420 emitting 'assigned but never read' warning on a variable on the basis
20421 that it has an access type.
20422 (Check_References): Emit unreferenced warning when the scope is a
20425 2004-12-07 Robert Dewar <dewar@adacore.com>
20426 Ed Schonberg <schonberg@adacore.com>
20428 * exp_ch6.adb (Expand_Call): Add comment on handling of back end
20431 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
20432 leaving call unchanged.
20433 This deals with the case where the pragma Import specified
20434 an external name, to be handled by the back end.
20436 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
20437 subprogram which is Imported with convention Intrinsic if an
20438 External_Name argument is specified.
20439 (Process_Import_Or_Interface): Properly diagnose link name argument.
20440 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
20441 with Sem_Ch6.Cannot_Inline.
20442 (Process_Inline): Provide separate warning for inapplicable inline
20444 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
20445 treatment is uniform on different targets.
20447 2004-12-07 Ed Schonberg <schonberg@adacore.com>
20449 * exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
20450 construct is rewritten, preserve end label to permit source navigation.
20452 2004-12-07 Thomas Quinot <quinot@adacore.com>
20454 * exp_dist.adb (Specific_Build_General_Calling_Stubs,
20455 Specific_Build_Stub_Target): New subprograms.
20456 (Build_Subprogram_Calling_Stubs): Make this procedure independent from
20457 the PCS implementation used, using the above PCS-customized subprograms.
20458 Minor reformatting.
20459 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
20460 for generation of DSA code targeted to the PolyORB PCS.
20461 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
20462 implementation of the partition communication subsystem in ancillary
20464 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
20465 PolyORB_Support.Build_Stub_Type): New subrograms containing the
20466 PCS-specific part of Add_Stub_Type.
20467 (Insert_Partition_Check): Use runtime library function to perform
20470 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
20471 (RE_Same_Partition): New entity, from s-parint.
20473 * s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

20483 * g-os_lib.adb (Spawn): Explicitly initialize Saved_Error to avoid a
20484 compile-time warning.
20486 2004-12-07 Robert Dewar <dewar@adacore.com>
20488 * g-regpat.adb: (Match): Change a misuse of or to or else
20490 2004-12-07 Ed Schonberg <schonberg@adacore.com>
20493 (Generate_Reference): Handle properly a reference to an entry formal,
20494 when an accept statement has a pragma Unreferenced for it.
20496 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
20497 and the Has_Pragma_Unreferenced flag for each formal before analyzing
20498 the body, to ensure that warnings are properly emitted for each accept
20499 statement of a given task entry.
20501 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
20503 * Makefile.in: Add support for foreign threads on VMS.
20505 2004-12-07 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
20507 * misc.c (gnat_types_compatible_p, LANG_HOOKS_TYPES_COMPATIBLE_P):

20519 * nlists.adb (Prepend_Debug): Remove parameters and nest within
20521 (Remove_Next_Debug): Same fix
20523 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
20524 maintain back pointers now, though we did not used to, and comments
20526 (Prepend): Remove pragma Inline.
20527 (Remove_Next): Same cleanup
20529 2004-12-07 Thomas Quinot <quinot@adacore.com>
20531 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
20532 used to record an implicit dereference as a read operation on its
20533 prefix when operating under -gnatc. Necessary to avoid spurious
20534 'variable assigned but never read' warnings in that mode.
20535 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
20536 is a non-overloaded implicit dereference, call the above subprogram to
20537 ensure proper recording of references.
20539 2004-12-07 Gary Dismukes <dismukes@adacore.com>
20541 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
20542 to be resolved later as part of Analyze_Iteration_Scheme's call to
20545 2004-12-07 Ed Schonberg <schonberg@adacore.com>
20547 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

20558 documentation of the behaviour of these functions when passed an IP
20559 address that has no record in the system hosts database and no reverse

20572 Add some ??? comments asking for more comments
20574 * s-poosiz.adb: Minor reformatting
20575 Add comments on alignment requirement
20577 * sinfo.ads: Remove obsolete comment and fix typo.
20579 2004-12-07 Vincent Celier <celier@adacore.com>
20580 Sergey Rybin <rybin@adacore.com>
20582 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
20583 Files" with the new tool and package names.
20584 Reformatting to suppress most of the warnings for line too long
20585 Document the new section "Project Search Path:" in the output of
20587 Add gnatmetric section
20589 2004-12-07 Vincent Celier <celier@adacore.com>
20591 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
20592 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
20593 and -eit to -ept. Added qualifier
20594 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
20596 2004-11-27 Andreas Schwab <schwab@suse.de>
20598 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
20600 2004-11-25 Arnaud Charlet <charlet@adacore.com>
20602 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
20603 internal implementation unit GNAT.Sockets.Thin,
20604 as their usage for sockets is non-portable (using the read and write
20605 functions from the system runtime library is fine on UNIX but won't
20606 work under Windows).
20608 * mingw32.h: Update copyright notice.
20610 2004-11-25 Arnaud Charlet <charlet@adacore.com>
20612 * ada-tree.h: Minor reformatting of previous change to avoid lines
20613 longer than 79 characters.

20647 (__gnat_is_symbolic_link): Enable the effective body of this
20648 function when __APPLE__ is defined.
20650 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
20653 2004-11-18 Olivier Hainque <hainque@adacore.com>
20655 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
20656 address of which may be used to represent "others" and "all others"
20657 choices in exception tables, instead of the current harcoded
20658 (void *)0 and (void *)1.
20659 (Setup_Exception): Do nothing in the GNAT SJLJ case.
20661 * gigi.h (others_decl, all_others_decl): New decls representing the
20662 new Others_Value and All_Others_Value objects.
20663 (struct attrib): Rename "arg" component as "args", since GCC expects a
20664 list of arguments in there.
20666 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
20667 corresponding objects exported by a-exexpr, instead of hardcoded dummy
20670 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
20671 others_decl and all_others_decl instead of hardcoded dummy addresses
20672 to represent "others" and "all others" choices, which is cleaner and
20673 more flexible with respect to the possible eh pointer encoding policies.
20675 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
20676 (process_attributes): Account for the naming change of the "args"
20677 attribute list entry component.
20679 * decl.c (build_attr_list): Rename into prepend_attributes to allow
20680 cumulating attributes for different entities into a single list.
20681 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
20682 attributes for the current entity and propagate first subtype
20683 attributes to other subtypes.
20684 <E_Procedure>: Attribute arguments are attr->args and not
20685 attr->arg any more.
20686 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
20687 argument provided, as this is what GCC expects. Use NULL_TREE instead
20690 2004-11-18 Robert Dewar <dewar@adacore.com>
20692 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
20693 Minor reformatting througout (including new function specs)
20694 Add ??? comments asking for clarification.
20696 2004-11-18 Thomas Quinot <quinot@adacore.com>
20698 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
20699 incomplete duplicate implementation of this subprogram from butil.
20701 2004-11-18 Thomas Quinot <quinot@adacore.com>
20703 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
20704 procedures factors the common processing for building an RPC receiver
20705 for an RCI package or an RACW type.
20706 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
20707 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
20708 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
20710 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of

20718 string distribution identifiers assigned to a given subprogram.
20719 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
20720 (Add_RAS_Dereference_TSS): Add comments.
20721 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
20722 is not referenced yet because it will be used by the PolyORB DSA
20724 (Insert_Partition_Check): Remove fossile code.
20725 (First_RCI_Subprogram_Id): Document this constant.
20726 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
20728 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
20729 replaced with calls to Get_Library_Unit_Name_String. Previously there
20730 were several instances of the same code in different locations in the
20731 compiler; this checkin completes the replacement of all of these
20732 instances with calls to a common subprogram.
20733 Minor reformatting.
20735 * sem_dist.adb: Remove comment noting that RPC receiver generation
20736 should be disabled for RACWs that implement RASs.

20743 if the context comes from source.
20745 * snames.ads (PCS_Names): New subtype corresponding to names of
20746 supported implementations of the Partition Communication Subsystem
20747 (PCS) (i.e. the runtime library support modules for the distributed

20761 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
20762 (Expand_Pragma_Psect_Object): New procedure
20763 These procedures contain the revised and cleaned up processing for
20764 these two pragmas. This processing was formerly in Sem_Prag, but
20765 is more appropriately moved here. The cleanup involves making sure
20766 that the pragmas are properly attached to the tree, and that no
20767 nodes are improperly shared.
20769 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
20770 pragmas to Exp_Prag, which is more appropriate.
20771 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
20772 check for duplicates Remove use of Is_Psected flag, no longer needed.
20773 Use new Make_String_Literal function with string.
20775 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
20776 that are functions return universal values, that have to be converted
20777 to the context type.
20778 Use new Make_String_Literal function with string.
20779 (Get_Stream_Convert_Pragma): New function, replaces the use of
20780 Get_Rep_Pragma, which had to be kludged to work in this case.
20782 * freeze.adb: Use new Has_Rep_Pragma function
20784 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
20785 function with string.
20786 Use new Has_Rep_Pragma function.
20788 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
20791 2004-11-18 Robert Dewar <dewar@adacore.com>
20793 * errout.ads, errout.adb: (First_Sloc): New function
20795 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
20796 check (-gnatyx) instead of being included as a redundant construct
20799 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
20800 Style_Check_Order_Subprograms.
20802 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
20803 stylesw.adb: Add Style_Check_Xtra_Parens
20805 * usage.adb: Add line for -gnatyx (check extra parens)

20810 Robert Dewar <dewar@adacore.com>
20812 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
20813 discriminant of a constrained subtype, analyze the copy of the
20814 corresponding constraint, because in some cases it may be only
20815 partially analyzed.
20816 Removes long-lived ??? comments.
20818 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
20819 handled controlled or secondary-stack expressions within the
20820 iteration_scheme of a loop.
20822 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
20823 bounds that may contain functions calls, to prevent memory leaks when
20824 the bound contains a call to a function that uses the secondary stack.
20825 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
20826 generate temporaries for loop bounds that might contain function calls
20827 that require secondary stack and/or finalization actions.
20829 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
20830 selected component and the selector is overloadable (not just a
20831 function) treat as function call, Analyze_Call will disambiguate if
20833 (Analyze_Selected_Component): Do not generate an actual subtype for the
20834 selected component if expansion is disabled. The actual subtype is only
20835 needed for constraint checks.
20836 (Analyze_Allocator): If restriction No_Streams is set, then do
20837 not permit objects to be declared of a stream type, or of a
20838 composite type containing a stream.
20840 * restrict.ads: Remove the a-stream entry from Unit_Array, since
20841 No_Streams no longer prohibits with'ing this package.
20843 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
20844 discriminants, but the parent base has unknown discriminants, there is
20845 no discriminant constraint to inherit. Such a discrepancy can arise
20846 when the actual for a formal type with unknown discriminants is a
20847 similar private type whose full view has discriminants.
20848 (Analyze_Object_Declaration): If restriction No_Streams is set, then
20849 do not permit objects to be declared of a stream type, or of a
20850 composite type containing a stream.
20852 2004-11-18 Ed Schonberg <schonberg@adacore.com>
20854 * exp_dbug.ads: Update documentation to reflect simpler encoding for
20855 protected operations.
20857 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
20858 generated name, it complicates decoding in gdb and hinders debugging
20859 of protected operations.
20860 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
20861 flag for the protected entry barrier function.
20862 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
20863 flag for the protected entry function.

20869 * Makefile.in: Inform the value of the variable GMEM_LIB in the
20870 Darwin-specific section.
20872 * lang-specs.h: Change the placement of the %1 marker.
20873 Works around the fact that gcc adds -fPIC by default under Darwin.

20877 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
20878 type of the object with the packed array type, set the Analyzed flag
20879 on the object if it is an entity or simple indexed component, to avoid
20880 spurious type errors.
20882 2004-11-18 Gary Dismukes <dismukes@adacore.com>
20884 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
20885 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
20886 separate line from the version message.
20888 2004-11-18 Ed Falis <falis@adacore.com>
20890 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
20892 (init_float): Eliminate initialization of floating point status for
20893 AE653. The instructions have no effect for vThreads.
20895 2004-11-18 Vincent Celier <celier@adacore.com>
20897 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
20898 gnatbind is invoked with -shared.
20900 2004-11-18 Jose Ruiz <ruiz@adacore.com>
20902 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
20903 for Detect_Blocking which is redundant with the check done within the
20904 procedure Protected_Single_Entry_Call.
20905 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
20906 Detect_Blocking which is redundant with the check done within the
20907 procedure Protected_Single_Entry_Call.
20909 2004-11-18 Vincent Celier <celier@adacore.com>
20911 * makegpr.adb (Compile): Put the compiling switches (in package
20912 Compiler and on the command line) immediately after "-c", instead of
20913 at the end of the command line invocation of the compiler, when
20914 compiling a non-Ada file.
20915 (Build_Global_Archive): When there is no need to rebuild the archive,
20916 set Global_Archive_Exists, so that the archive is passed to the linker
20919 2004-11-18 Robert Dewar <dewar@adacore.com>
20920 Sergey Rybin <rybin@adacore.com>
20923 Remove extra paren check from list of checks for redundant constructs
20924 Add documentation of new -gnatyx style check (check extra parens)
20925 Remove paragraph about gnatelim debug options.
20927 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
20928 objects rather than forbidding dependencies on the package Ada.Streams.
20930 * sinfo.ads: Add ??? note that we should document pragmas passed to
20933 * g-expect.ads: Fix a few typos in the comments.
20935 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
20937 * misc.c (gnat_handle_option): Use %< and %> for quoting in
20940 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
20942 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
20944 2004-11-07 Andreas Schwab <schwab@suse.de>
20946 * Makefile.in (install-gnatlib): Remove spurious hyphen.
20948 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
20951 * Makefile.in (darwin): Set soext to .dylib.
20953 2004-10-26 Vincent Celier <celier@gnat.com>
20954 Thomas Quinot <quinot@act-europe.fr>
20956 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
20957 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
20958 there is no use of GNAT.Sockets.Constants.
20959 Remove remaining pragma Import for C_Write
20960 Remove C_Read and C_Write from internal implementation unit
20961 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
20962 the read and write functions from the system runtime library is fine
20963 on UNIX but won't work under Windows).
20965 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
20966 (Check_Selector): Use C_Recv instead of C_Read.
20967 Selectors are the GNAT.Sockets abstraction to perform a select()
20968 call on a set of descriptors. To allow abortion of an ongoing
20969 select operation, some data is written to a dedicated socket that
20970 is always monitored.
20971 Under Windows, the write and read library functions cannot operate
20972 on sockets, so we need to use send and recv instead, which is portable
20973 across all supported platforms.
20975 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
20976 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
20977 (using the read and write functions from the system runtime library is
20978 fine on UNIX but won't work under Windows).
20980 2004-10-26 Nicolas Setton <setton@act-europe.fr>
20982 * mlib-tgt-darwin.adb: New file.
20984 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
20985 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
20986 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
20987 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
20990 * Makefile.in: Add support for building shared libraries under Darwin.
20991 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
20992 the low level EH init subprogram to be called from __gnat_initialize.
20994 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
20995 indicates which options to pass to the archive indexer.
20997 * mlib-utl.adb: Add support for calling ranlib with additional
20998 options. This is needed for instance under Mac OS X.
20999 (Ranlib_Options): New global variable, used to store the potential
21000 options to pass to ranlib.
21001 (Ar): Use Ranlib_Options when spawning ranlib.
21002 (Initialize): Set the value of ranlib option.
21004 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
21006 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
21007 instead of 8K, to reflect the real potential needs for stack-checking
21010 2004-10-26 Pascal Obry <obry@gnat.com>
21012 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
21014 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
21015 Windows only the initial thread stack size can be set so it is good to
21016 start we a low stack size.
21017 The OS will adjust the size as needed.
21019 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
21020 Nicolas Setton <setton@act-europe.fr>
21022 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
21023 "__unix__" instead of "unix".
21024 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
21025 sections were just mistakenly ignored. The former is
21026 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
21027 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
21028 of hpux. This prevents an unwanted definition of the symbol
21029 convert_addresses in adaint.o.
21031 2004-10-26 Gary Dismukes <dismukes@gnat.com>
21033 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
21034 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
21036 2004-10-26 Cyrille Comar <comar@act-europe.fr>
21038 * a-filico.ads, a-filico.adb: fix incorrect header.
21040 2004-10-26 Javier Miranda <miranda@gnat.com>
21042 * a-ststio.ads: Fix typo in identifier
21044 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21046 * sem_ch4.adb: Minor reformatting.
21048 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21050 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
21051 enabled, check the result of unary and binary operations when the
21052 expression is the right-hand side of an assignment.
21054 2004-10-26 Vincent Celier <celier@gnat.com>
21056 * clean.adb (Delete): Do not output warnings when in quiet output and
21057 not in verbose mode.
21058 (Force_Deletions): New Boolean flag, defaulted to False
21059 (Delete): Only delete a file if it is writable, and when
21060 Force_Deletions is True.
21061 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
21062 (Usage): Line for new switch -f
21063 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
21066 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
21068 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
21069 JM type only if its size matches that of the wrapper. When a size is
21070 prescribed and the field is not aliased, remove the wrapper of a JM
21071 type only if the size is not greater than that of the packed array.
21072 (gnat_to_gnu_entity): Change the extension of packed array wrappers
21075 2004-10-26 Geert Bosch <bosch@gnat.com>
21077 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
21078 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
21079 (Pred): Implement in terms of Succ.
21081 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21083 * exp_aggr.adb (Safe_Component): An aggregate component that is an
21084 unchecked conversion is safe for in-place use if the expression of the
21085 conversion is safe.
21086 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
21087 be expandable in place even if the aggregate does not come from source.
21088 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
21089 designated object of an allocator in place, rather than building it
21090 first on the stack. The previous scheme forces a full copy of the array,
21091 and may be altogether unsusable if the size of the array is too large
21092 for stack allocation.
21094 2004-10-26 Robert Dewar <dewar@gnat.com>
21096 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
21097 compares if the component is atomic.
21099 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
21100 array assignment if the component type is atomic.
21102 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21103 Eric Botcazou <ebotcazou@act-europe.fr>
21105 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
21106 is aliased and is a by_reference type, do not pass by copy.
21107 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
21108 detect whether the call is in the right side of an assignment or
21109 the expression of an object declaration. Recurse on component
21110 association within aggregates.
21111 Call it in the condition that determines whether the temporary is
21112 necessary for correct stack-checking.
21114 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21116 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
21117 RACW_Type, used in the PolyORB version.
21118 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
21119 version and the GARLIC version.
21121 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
21122 Rename RCI_Info to RCI_Locator for better consistency between the
21123 GARLIC and PolyORB versions of the distributed systems annex.
21124 (DSA_Implementation_Name): This enumeration lists the possible
21125 implementations of the Partition Communication Subsystem for the
21126 Distributed Systems Annex (DSA). The three available implementations
21127 are the dummy stub implementation (No_DSA), and two versions based on
21128 two different distribution runtime libraries: GARLIC and PolyORB. Both
21129 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
21131 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
21134 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
21135 between the GARLIC and PolyORB versions of the distributed systems
21137 Remove RE_Unbounded_Reclaim_Pool since it is unused.
21139 2004-10-26 Gary Dismukes <dismukes@gnat.com>
21141 * gnat1drv.adb: Suppress calling the back end when
21142 Frontend_Layout_On_Target is true.
21144 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21146 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
21147 Set_Read_Only): New subprograms.
21148 These new routines allow the user to set or unset the Owner execute
21149 and Owner write permission flags on a file.
21151 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
21152 GNAT.OS_Lib.Set_Executable instead of rolling our own.
21154 2004-10-26 Matthew Gingell <gingell@gnat.com>
21156 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
21158 2004-10-26 Pascal Obry <obry@gnat.com>
21160 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
21161 memory before the faulting page we properly test the process read
21162 access for this address using appropriate Win32 routine.
21163 (HPUX sections): guard with "__hpux__" instead of "hpux".
21165 2004-10-26 Robert Dewar <dewar@gnat.com>
21167 * lib-xref.adb (Generate_Reference): Don't complain about reference to
21168 entry parameter if pragma Unreferenced set, since we do not properly
21169 handle the case of multiple parameters.
21171 2004-10-26 Vincent Celier <celier@gnat.com>
21173 * prj-env.adb: (Contains_ALI_Files): New Boolean function
21174 (Ada_Objects_Path.Add): For a library project, add to the object path
21175 the library directory only if there is no object directory or if the
21176 library directory contains ALI files.
21177 (Set_Ada_Paths.Add.Recursive_Add): Ditto
21179 2004-10-26 Vincent Celier <celier@gnat.com>
21181 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
21182 extension of library projects.
21184 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
21185 path defaults to ".:<prefix>/lib/gnat".
21186 (Parse): For an extending all project, allow direct import of a project
21187 that is virtually extended.
21189 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
21190 the specified name is directly imported, return its ID. Otherwise, if
21191 an extension of this project is imported, return the ID of the
21194 2004-10-26 Robert Dewar <dewar@gnat.com>
21196 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
21197 (Sub3): New procedure, used by Scaled_Divide
21198 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
21199 correct more than one instance of failure to propagate carries
21201 (Double_Divide): Handle overflow case of largest negative number
21202 divided by minus one.
21204 * s-arit64.ads (Double_Divide): Document that overflow can occur in
21205 the case of a quotient value out of range.
21208 2004-10-26 Robert Dewar <dewar@gnat.com>
21210 * s-bitops.adb (Bit_Eq): Remove redundant check.
21212 * s-bitops.ads: Minor comment updates
21213 Change some occurrences of Address to System.Address
21215 * s-carsi8.ads: Fix minor cut-and-paste error in comments
21217 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21219 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
21220 accessibility check to prefix that is a protected operation.
21222 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21224 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
21225 empty, post message on stub.
21227 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21228 Javier Miranda <miranda@gnat.com>
21230 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
21231 current instance appears within a unit that is directly in the context
21233 Used to determine whether the body of the instance should be analyzed
21234 immediately after its spec, to make its subprogram bodies available
21235 for front-end inlining.
21236 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
21237 constraint is not allowed on the component type (AARM 12.5.3(3))
21239 2004-10-26 Cyrille Comar <comar@act-europe.fr>
21241 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
21242 'Storage_Pool): enhance, document & limit detection of non-sharable
21245 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
21247 * s-pooglo.ads: Add more documentation now that this pool is properly
21250 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21252 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
21253 or protected type with discriminants, do not constrain the
21254 corresponding record type if the subtype declaration has no
21255 discriminant constraints. This can be the case in source code, or in
21256 the subtype declaration created to rename an actual type within an
21259 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21261 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
21262 different kind of stub (possibly wrong name for file), do not check
21264 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
21265 includes call to some function that returns an unconstrained type, do
21268 2004-10-26 Ed Schonberg <schonberg@gnat.com>
21270 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
21271 appear in the code for the main unit. Dependencies among units in the
21272 context of the main unit are established when those other units are
21273 compiled. Otherwise spurious elaboration constraints can generate
21274 incorrect elaboration circularities.
21276 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
21277 Ed Schonberg <schonberg@gnat.com>
21279 * sem_util.adb (Is_Aliased_View): Defend against the case where this
21280 subprogram is called with a parameter that is not an object name. This
21281 situation arises for some cases of illegal code, which is diagnosed
21282 later, and in this case it is wrong to call Is_Aliased, as that might
21283 cause a compiler crash.
21284 (Explain_Limited_Type): Refine previous fix to include
21285 inherited components of derived types, to provide complete information.
21287 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
21288 is the prival for a protected object.
21289 It is necessary to mark this entity as a variable, in addition to
21290 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
21291 modified to avoid checking the Aliased flag on entities that are not
21292 objects. (Checking that flag for non-objects is erroneous and could
21293 lead to a compiler crash).
21295 2004-10-26 Robert Dewar <dewar@gnat.com>
21297 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
21298 X_Frac = 0.5, then we know that the number X must be positive.
21299 (Succ): Remove the same redundant test, and also fix the primary test
21300 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
21302 (Decompose): Add fuller comments to spec
21304 2004-10-26 Pascal Obry <obry@gnat.com>
21306 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
21307 validity (process must have read access). Set to 0 in all other cases.
21308 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
21309 violation on Win32.
21310 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
21311 segmentation violation.
21313 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
21315 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
21316 whose type is a constructed subtype of an aliased object with an
21317 unconstrained nominal subtype, convert the actual to the constructed
21318 subtype before taking its address.
21320 2004-10-26 Vincent Celier <celier@gnat.com>
21322 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
21323 (Is_Path_Name_Case_Sensitive): New function
21325 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
21326 (Base_Name, Simple_Name, Current_Directory, Compose,
21327 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
21330 2004-10-26 Cyrille Comar <comar@act-europe.fr>
21331 Vasiliy Fofanov <fofanov@act-europe.fr>
21332 Vincent Celier <celier@gnat.com>
21334 * gnat_ugn.texi: Generalize "finding memory problems" section into a
21335 "memory management issues" section and document some of the useful
21336 memory pools provided as part of the GNAT library.
21337 Remove "virtual" from declaration of A::method2 in
21338 the simple example of Ada/C++ mixed system.
21339 Library Projects may be virtually extended: their virtual extensions
21340 are not Library Projects.
21341 Added section on extending project hierarchies.
21343 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
21345 * adaint.c (__gnat_get_libraries_from_registry): Cast value
21347 (__gnat_portable_spawn): Remove const.
21349 * mingw32.h (MAXPATHLEN): Check for previous definition.
21351 2004-10-17 Matthias Klose <doko@debian.org>
21353 * gnatvsn.ads: Set gnat library version to 4.0.
21355 2004-10-05 Vincent Celier <celier@gnat.com>
21357 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
21359 2004-10-04 Laurent GUERBY <laurent@guerby.net>
21362 * Makefile.in: Define and use RANLIB_FLAGS.
21364 2004-10-04 Pascal Obry <obry@gnat.com>
21366 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
21367 other x86 platforms).
21369 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
21371 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
21372 in general and triggers stack alignment adjustment for thread entry
21373 points on targets where this is necessary.
21375 2004-10-04 Bernard Banner <banner@gnat.com>
21378 * Makefile.in: Add section for powerpc linux
21379 Add variant i-vxwork-x86.ads
21381 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
21383 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
21385 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
21386 table registration calls when need be. Ensures no reference to the crt
21387 ctors symbol are issued in the SJLJ case, which avoids possible
21388 undefined symbol errors in the case of modules to be statically linked
21391 2004-10-04 Javier Miranda <miranda@gnat.com>
21393 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
21394 in-line the code corresponding to subprogram Analyze_Actuals. In
21395 addition, analyze the actuals only in case of subprogram call.
21397 2004-10-04 Ed Falis <falis@gnat.com>
21399 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size

21410 (Analyze_Block_Statement): Add circuitry to detect following dead code
21411 (Check_Unreachable_Code): Handle case of block exit
21413 2004-10-04 Robert Dewar <dewar@gnat.com>
21415 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
21416 (XMatchD): Avoid warning for Logic_Error call
21418 2004-10-04 Robert Dewar <dewar@gnat.com>
21420 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
21421 consider expressions buried within a procedure actual to be an actual.
21422 This caused some blowups with uses of packed slices within a procedure
21425 2004-10-04 Robert Dewar <dewar@gnat.com>
21427 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
21428 longer need to be initialized to zero.
21429 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
21430 initialized to zero.
21432 * checks.adb (Expr_Known_Valid): Packed arrays are now always
21433 considered valid, even if the representation is modular. That's correct
21434 now that we no longer initialize packed modular arrays to zero.
21436 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
21437 suffixes. These are now documented as the only cases in which the
21438 debugger ignores outer records.
21439 Previously, the spec allowed arbitrary suffixes for this purpose.
21440 Change name of LJM to JM for packed array pad records
21441 Create separate section on packed array handling, and add a whole new
21442 set of comments to this section describing the situation with packed
21443 modular types and justification requirements depending on endianness.
21445 2004-10-04 Robert Dewar <dewar@gnat.com>
21447 * a-except.adb: Add a comment for last change
21449 * einfo.ads: Minor spelling correction in comment
21451 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
21453 * sem_ch11.adb: Fix a case of using | instead of \ for continuation

21460 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
21461 Inline_Always when in Configurable_Run_Time mode.
21463 * sem_prag.adb (Process_Convention): If entity is an inherited
21464 subprogram, apply convention to parent subprogram if in same scope.
21465 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
21466 when in Configurable_Run_Time mode.
21468 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21470 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
21471 class_wide type after component list has been inherited.

21475 * sem_ch12.adb (Check_Generic_Actuals): New predicate
21476 Denotes_Previous_Actual, to handle properly the case of a private
21477 actual that is also the component type of a subsequent array actual.
21478 The visibility status of the first actual is not affected when the
21479 second is installed.
21480 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
21481 make fully recursive the treatment of formals of packages declared
21483 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
21484 the above on exit from an instantiation.
21485 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
21486 current instantiation which is now complete.
21487 (Analyze_Package_Instantiation): No instantiated body is needed if the
21488 main unit is generic. Efficient, and avoid anomalies when a instance
21489 appears in a package accessed through rtsfind.
21491 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21493 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
21494 do not generate a declaration for a temporary if the call is part of a
21495 library-level instantiation.
21497 2004-10-04 Ed Schonberg <schonberg@gnat.com>
21499 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
21500 searching for a limited component to flag.
21502 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
21503 expansion of Input, to account for the fact that the implicit call
21504 generated by the attribute reference must freeze the user-defined
21505 stream subprogram. This is only relevant to 'Input, because it can
21506 appear in an object declaration, prior to the body of the subprogram.
21508 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
21509 expansion can proceed and further errors uncovered.
21510 (Minor clean up): Fix cases of using | instead of \ for continuation
21513 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
21515 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
21517 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
21518 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
21519 Use gcc_assert and gcc_unreachable.
21521 * decl.c (gnat_to_gnu_entity, case object): Check and process a
21522 specified alignment before validating size.
21523 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
21524 stripped-down declaration for the type of the inner field when making
21527 * utils.c (finish_record_type): Do not compute the size in units
21528 incrementally. Instead compute it once for the rep clause case.
21529 Use gcc_assert and gcc_unreachable.
21531 2004-10-04 Vincent Celier <celier@gnat.com>
21533 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
21535 (Is_Valid_Path_Name): Take '/' as a directory separator.
21537 2004-10-04 Vincent Celier <celier@gnat.com>
21539 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
21540 (Extended_Project) only if Extended_Project is defined, to avoid
21542 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
21544 (Parse_Single_Project): Ditto.
21546 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
21547 Add_To_Project_Path for virtual projects.
21549 2004-10-04 Vincent Celier <celier@gnat.com>
21551 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

21555 parameter Options_2.
21557 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
21558 Build_Dynamic_Library with an empty Options_2.
21560 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
21563 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
21564 directory separator, if any.
21565 (Gprmake): Do not allow mains on the command line for library projects.
21566 Do not attempt to link when the project is a library project.
21567 (Library_Opts): New table to store Library_Options.
21568 (Build_Library): If Library_Options is specified, pass these options
21569 when building a shared library.
21571 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
21573 * s-tposen.adb (Service_Entry): The object must be always unlocked at
21574 the end of this procedure now that the unlock operation was inserted
21577 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
21579 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
21580 corresponding to the Preallocated_Stacks flags in System.
21581 (Get_Target_Parameters): Including the processing for
21582 Preallocated_Stacks.

21590 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
21591 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
21592 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
21593 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
21594 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
21595 used to signal whether the compiler creates the required stacks and
21596 descriptors for the different tasks (when True) or it is done by the
21597 underlying operating system at run time (when False).
21598 It is initially set to False in all targets.
21600 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
21601 if it is supported by the target.
21602 (Make_Task_Create_Call): Pass the stack address if it has been
21603 previously created. Otherwise pass a Null_Address.
21605 * snames.adb: Add _stack.
21607 * snames.ads: Add Name_uStack. Required to allow the expander to
21608 statically allocated task stacks.
21610 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
21611 Stack_Address argument.
21612 Check that its value is equal to Null_Address because this target does
21613 not support the static stack allocation.
21615 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
21617 * usage.adb: Change "pragma inline" to "pragma Inline" in information
21620 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
21622 * exp_dist.adb: Split declaration of asynchronous flag out of
21623 Add_RACW_Read_Attribute.
21624 Minor reformatting for better alignment with PolyORB version.
21625 Store the entity for the asynchronous flag of an RACW, rather than the
21626 expression, in the asynchronous flags table. This will allow this flag
21627 to be used in other subprograms beside Add_RACW_Read_Attribute.
21629 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
21631 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
21632 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,

21634 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
21635 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
21636 sockets constant MSG_NOSIGNAL (Linux-specific).
21637 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
21638 all Send operations.
21639 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
21640 from trigerring SIGPIPE.
21641 Rename components to avoid clash with Ada 2005 possible reserved
21643 (Check_Selector): When the select system call returns with an error
21644 condition, propagate Socket_Error to the caller.
21646 2004-10-01 Jan Hubicka <jh@suse.cz>
21648 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

21656 Change "pragma inline" to "pragma Inline" in information and error
21658 Minor reformatting.
21660 * freeze.adb (Check_Address_Clause): Remove previous change, not the
21661 right way of doing things after all.
21662 (Freeze_Entity): For object, set Is_Public for imported entities
21663 unless there is an address clause present.
21665 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
21667 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
21668 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
21669 ensures proper handling of types with rep clauses, which might have
21670 their TYPE_SIZE set already.
21672 2004-09-21 Robert Dewar <dewar@gnat.com>
21674 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
21675 packed array types in both little- and big-endian cases. This change
21676 ensures that we no longer count on the unused bits being initialized
21677 for such types (and in particular ensures that equality testing will
21678 only read the relevant bits).
21679 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
21680 These changes mean that we no longer need to initialize small packed
21682 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
21683 optimization to an LJM field as to its parent field.
21685 * ada-tree.h, trans.c, utils.c, utils2.c:
21686 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
21688 2004-09-20 Jan Hubicka <jh@suse.cz>
21690 * utils.c (gnat_finalize): Remove.
21691 (end_subprog_body): Directly call cgraph_finalize_function;
21692 do not lower the nested functions.
21694 2004-09-20 Robert Dewar <dewar@gnat.com>
21697 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
21698 if an address clause is present, since that means that the Import
21701 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
21703 * 5tsystem.ads: Removed, no longer used.
21705 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
21706 Zack Weinberg <zack@codesourcery.com>
21708 * ada-tree.def: Use tree_code_class enumeration constants
21709 instead of code letters.
21710 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
21711 Update for new tree-class enumeration constants.

21726 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
21727 an existing directory.
21728 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
21729 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
21730 Convert the result to File_Size.
21732 * prj.ads: (Project_Error): New exception
21734 * prj-attr.adb: Except in procedure Initialize, Fail comes from
21735 Prj.Com, not from Osint.
21736 (Attrs, Package_Attributes): Tables moved to private part of spec
21737 (Add_Attribute, Add_Unknown_Package): Moved to new child package
21739 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
21740 Prj.Project_Error after call to Fail.
21741 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
21742 Fail. Check that package name is not already in use.
21744 * prj-attr.ads: Comment updates to indicate that all subprograms may be
21745 used by tools, not only by the project manager, and to indicate that
21746 exception Prj.Prj_Error may be raised in case of problem.
21747 (Add_Unknown_Package, Add_Attribute): Moved to new child package
21749 (Attrs, Package_Attributes): Table instantiations moved from the body to
21750 the private part to be accessible from Prj.Attr.PM body.

21753 from new package Prj.Attr.PM.
21754 (Parse_Attribute_Declaration): Call Add_Attribute from new package
21757 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
21759 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
21760 instead of Elaboration_Checks).
21762 * a-calend.adb: Minor reformatting
21764 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

21822 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
21823 Common_ATCB record. It contains the dynamic level of protected action
21824 nesting for each task. It is needed for checking whether potentially
21825 blocking operations are called from protected operations.

21863 contains the required machinery for handling that.
21865 * sem_util.ads: Change comment associated to procedure
21866 Check_Potentially_Blocking_Operation.
21867 This procedure does not insert a call for raising the exception because
21868 that is currently done by the run time.
21870 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
21872 * init.c: Add the global variable __gl_detect_blocking that indicates
21873 whether pragma Detect_Blocking is active (1) or not (0). Needed for
21874 making the pragma available at run time.
21875 (__gnat_set_globals): Pass and update the detect_blocking parameter.
21877 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
21878 pragma Detect_Blocking is active.
21880 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
21882 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
21883 DB is found in the ali file. Any unit compiled with pragma
21884 Detect_Blocking active forces its effect in the whole partition.
21886 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
21887 Detect_Blocking is active and delay is called from a protected
21890 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
21891 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
21892 Detect_Blocking is active (0 otherwise).
21893 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
21894 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
21897 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
21899 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
21900 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
21903 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
21904 (Register_Receiving_Stub): Add Subp_Info formal parameter.
21905 Update API in placeholder implemetation of s-parint to reflect changes
21906 in distribution runtime library.
21908 * sem_ch3.adb (Expand_Derived_Record): Rename to
21909 Expand_Record_Extension.
21911 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
21912 primitive operations of potentially distributed object types that have
21913 non-controlling anonymous access formals.
21915 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
21917 New implementation of expansion for remote access-to-subprogram types,
21918 based on the RACW infrastructure.
21919 This version of sem_dist is compatible with PolyORB/DSA as well as
21922 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
21923 Asynchrronous that applies to a remote access-to-subprogram type, mark
21924 the underlying RACW type as asynchronous.
21926 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
21927 __gnat_using_gnu_linker to 1.
21929 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
21930 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

21936 * exp_ch3.adb (Expand_Derived_Record): Rename to
21937 Expand_Record_Extension.
21938 (Build_Record_Init_Proc.Build_Assignment): The default expression in
21939 a component declaration must remain attached at that point in the
21940 tree so New_Copy_Tree copies it if the enclosing record type is derived.
21941 It is therefore necessary to take a copy of the expression when building
21942 the corresponding assignment statement in the init proc.
21943 As a side effect, in the case of a derived record type, we now see the
21944 original expression, without any rewriting that could have occurred
21945 during expansion of the ancestor type's init proc, and we do not need
21946 to go back to Original_Node.
21948 * exp_ch3.ads (Expand_Derived_Record): Rename to
21949 Expand_Record_Extension.
21951 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

21954 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
21955 New subprograms. Used to create a proxy tagged object for a remote
21956 subprogram. The proxy object is used as the designated object
21957 for RAS values on the same partition (unless All_Calls_Remote applies).
21958 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
21959 System.Partition_Interface.Get_Unique_Remote_Pointer.
21960 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
21961 Renamed from Add_RAS_*_Attribute.
21962 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
21964 New implementation of expansion for remote access-to-subprogram types,
21965 based on the RACW infrastructure.
21967 * exp_dist.ads (Copy_Specification): Update comment to note that this
21968 function can copy the specification from either a subprogram
21969 specification or an access-to-subprogram type definition.
21971 2004-09-09 Ed Schonberg <schonberg@gnat.com>
21973 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
21974 in an instance, between an explicit subprogram an one inherited from a
21975 type derived from an actual.
21977 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
21978 add a polling call if the subprogram is to be inlined by the back-end,
21979 to avoid repeated calls with multiple inlinings.
21981 * checks.adb (Apply_Alignment_Check): If the expression in the address
21982 clause is a call whose name is not a static entity (e.g. a dispatching
21983 call), treat as dynamic.
21985 2004-09-09 Robert Dewar <dewar@gnat.com>
21987 * g-trasym.ads: Minor reformatting
21989 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

21995 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
21998 2004-09-09 Pascal Obry <obry@gnat.com>
22000 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
22001 enable map file generation. Add the right option to generate the map
22002 file if Map_File is set to True.
22004 * gnatdll.adb (Gen_Map_File): New variable.
22005 (Syntax): Add info about new -m (Map_File) option.
22006 (Parse_Command_Line): Add support for -m option.
22007 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

22023 2004-09-09 Cyrille Comar <comar@act-europe.fr>
22025 * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
22028 * opt.ads: Add Ada_Version_Runtime constant used to decide which
22029 version of the language is used to compile the run time.
22031 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
22033 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
22034 of variable length temporaries for function return now that the
22035 back-end and gigi support it.

22086 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
22087 packed indexed component where array is an IN OUT formal. This
22088 generated garbage code previously.
22090 * gnat_ugn.texi: Document -fverbose-asm
22092 * gnat-style.texi: Minor updates (note that boolean constants and
22093 variables are joined with AND/OR rather than short circuit forms).
22095 2004-09-01 Ed Schonberg <schonberg@gnat.com>
22097 * exp_util.adb (Safe_Unchecked_Type_Conversion): Conversion is safe if
22098 it is an upward conversion of an untagged type with no representation

22107 expander is not active (but check for unset reference to prefix of
22110 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
22111 pragma Debug as an if statement with a constant condition, for
22112 consistent treatment of entity references contained within the
22113 enclosed procedure call.
22115 2004-09-01 Vincent Celier <celier@gnat.com>
22117 * bindgen.adb: (Set_EA_Last): New procedure
22118 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
22120 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

22142 2004-09-01 Pascal Obry <obry@gnat.com>
22144 * gprcmd.adb (Extend): Do not output trailing directory separator. This
22145 is not needed and it confuses Windows GNU/make which does not report
22146 directory terminated by a slash as a directory.
22147 (gprcmd): Idem for "pwd" internal command.
22149 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
22150 target names rewrite to fix regressions with recent version of
22151 GNU/make. Starting with GNU/make 3.80 the pipe character was not
22152 handled properly anymore.

22202 2004-08-16 Pascal Obry <obry@gnat.com>
22204 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
22205 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
22206 option and not mdll anymore. Update comment.
22208 2004-08-16 Pascal Obry <obry@gnat.com>
22210 * bld.adb (Put_Include_Project): Properly handle directory separators
22213 2004-08-16 Ed Schonberg <schonberg@gnat.com>
22215 * sem_ch4.adb (Try_Object_Operation): Restructure code. Optimize by
22216 decreasing the number of allocated junk nodes while searching for the
22217 appropriate subprogram.

22226 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
22228 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
22229 for a global aliased object with a variable size and an unconstrained
22230 nominal subtype, pretend there is no initializer if the one we have is
22231 incomplete, and avoid referencing an inexistant component in there. The
22232 part we have will be rebuilt anyway and the reference may confuse
22233 further operations.
22235 2004-08-13 Thomas Quinot <quinot@act-europe.fr>

22253 2004-08-13 Ed Schonberg <schonberg@gnat.com>
22255 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
22256 unit, this is an attempt to inline a construct that is not available in
22257 the current restricted mode, so abort rather than trying to continue.
22259 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
22260 discriminants that rename those of the parent, recover names of
22261 original discriminants for the constraint on the full view of the
22263 (Complete_Private_Subtype): Do not create a subtype declaration if the
22264 subtype is an itype.
22266 * gnat_rm.texi: Added section on implementation of discriminated
22267 records with default values for discriminants.
22269 2004-08-13 Ed Schonberg <schonberg@gnat.com>
22272 * sem_res.adb (Make_Call_Into_Operator): Handle properly the case where
22273 the second operand is overloaded.

22287 from complaining on potential uninitialized reference.
22288 Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for
22289 new specification and test explicitly for non-zero return value.
22291 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
22292 returning C.int, to avoid using a derived boolean type.
22294 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
22295 Duplicate_Subexpr_No_Checks in preference to direct use of
22296 Remove_Side_Effects and New_Copy_Tree.

22320 2004-08-09 Olivier Hainque <hainque@act-europe.fr>
22322 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
22323 ignore overflows on low and high bounds of an index to also account for
22324 differences in signedness between sizetype and gnu_index_subtype.
22325 These are as legitimate as the ones caused by a lower TYPE_PRECISION
22328 2004-08-09 Robert Dewar <dewar@gnat.com>
22330 * s-solita.ads, s-solita.adb: Minor reformatting
22332 * gnat_rm.texi: Add documentation for pragma Profile (Restricted)
22333 Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new
22334 obsolescent section
22335 Add note that No_Implicit_Conditionals does not suppress
22336 run time constraint checks.
22338 * vms_conv.ads: Minor reformatting
22340 * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup
22341 and necessary for following change).
22342 (Mark): Return new format Mark_Id containing sec stack address
22343 (Release): Use sec stack address from Mark_Id avoiding Self call
22345 * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
22346 pointer (cleanup and necessary for following change).
22347 Define Mark_Id as record containing address of secondary stack, that way
22348 Release does not need to find the stack again, decreasing the number of
22349 calls to Self and improving efficiency.
22351 * sem_util.ads: Add a ??? comment for Is_Local_Variable_Reference
22353 * sem_ch5.adb (Analyze_Case_Statement): Add circuitry to track value of
22354 case variable into the individual case branches when possible.

24955 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
24956 operation when either operand is a literal, to avoid further
24959 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

26242 complete assignment subtree which is now unnecessary, as the expansion
26243 of inlined call has been improved to preserve a consistent assignment

26506 * osint.adb (Executable_Prefix): Set Exec_Name to the current
26507 executable name when not initialized. Otherwise, use its current value.
26509 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
26510 initialize it to another executable name than the current one. This
26511 allows to configure paths for an executable name (gnatmake) different
26512 from the current one (gnatdist).
26514 2004-03-29 Ed Schonberg <schonberg@gnat.com>
26516 * exp_ch6.adb (Expand_Call): A call to a function declared in the
26517 current unit cannot be inlined if it appears in the body of a withed
26518 unit, to avoid order of elaboration problems in gigi.
26520 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
26521 information for protected (wrapper) operation as well, to simplify gdb
26524 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

26563 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
26564 attribute reference does not denote a subtype, it can be any
26565 expression that has a classwide type, potentially after an implicit
26566 dereference. In particular, the prefix can be a view conversion for
26567 a classwide type (for which Is_Object_Reference holds), but it can
26568 also be a value conversion for an access-to-classwide type. In the
26569 latter case, there is an implicit dereference, and the original node
26570 for the prefix does not verify Is_Object_Reference.
26572 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
26573 conversion of a discriminant-dependent component of a mutable object
26576 2004-03-25 Ed Schonberg <schonberg@gnat.com>
26578 * freeze.adb (Freeze_Entity): When an inherited subprogram is
26579 inherited, has convention C, and has unconstrained array parameters,

26597 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
26598 value expressions to ensure that calls within a component definition
26599 will be checked (since those are evaluated during the record type's

26651 declaration for a child subprogram body that acts as a spec, indicate
26652 that the entity in the declaration needs debugging information.
26654 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
26655 full view if the subtype is created for a constrained record component;
26656 gigi has enough information to construct the record, and there is no
26657 place in the tree for the declaration.
26659 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
26660 serial number for the dummy body that is built for analysis, to avoid

26698 Minor reformatting.
26700 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
26702 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
26703 as regular exception objects and not as mere integers representing the
26704 condition code. The latter approach required some dynamics to mask off
26705 severity bits, which did not fit well into the GCC table based model.
26706 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
26707 exception data objects. We don't it and it would conflict with the other
26708 external symbol we have to generate for such exceptions.
26710 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
26711 the special code for VMS exceptions, since these are now represented
26712 as regular exceptions objects.

26755 When needed (stack checking) the stack size is retrieved
26756 from the VxWorks kernel.
26758 * Makefile.in: Flag -nostdinc is required when building the run time
26759 for avoiding looking for files in the base compiler.
26760 Add the VxWorks specific version of the package body for
26761 System.Stack_checking.Operations (5zstchop.adb).
26763 * Make-lang.in: Add the object file for
26764 System.Stack_Checking.Operations.

27006 explicit dereference.
27007 (Expand_N_Slice): Same. Always do the rewriting, even for the case
27008 of non-packed slices, since the dereference action generated by

27011 analyze and resolve the rewritten explicit dereference so it is seen
27013 (Insert_Dereference_Action): This procedure is now called only for the

28367 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
28368 (Type_May_Have_Bit_Aligned_Components): New function.
28370 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

28378 importing constant atomic/volatile objects.
28379 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
28380 unless explicit Pure_Function pragma given, to avoid insidious bug of
28381 call to non-pure imported function getting eliminated.

28384 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
28385 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

28403 * rtsfind.adb (Load_Fail): Give full error message in configurable
28404 run-time mode if all_errors mode is set. This was not done in the case
28405 of a file not found, which was an oversight.
28406 Note if secondary stack unit is used by compiler.
28408 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
28409 ineffective elaborate all pragmas on non-visible packages (this
28410 happened when a renamed subprogram was called). Now the elaborate all
28411 always goes on the package containing the renaming rather than the one
28412 containing the renamed subprogram.
28414 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
28415 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

28418 has an Etype that references an E_String_Literal.
28419 (Eval_String_Literal): Avoid assumption that N_String_Literal node
28420 always references an E_String_Literal_Subtype entity. This may not
28421 be true in the future.
28423 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
28426 * sem_res.adb (Resolve): Specialize msg for function name used in proc
28429 2004-01-05 Ed Falis <falis@gnat.com>

28434 2004-01-05 Vincent Celier <celier@gnat.com>
28436 * bld.adb: Minor comment updates
28437 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
28440 * make.adb (Gnatmake): Special process for files to compile/check when
28441 -B is specified. Fail when there are only foreign mains in attribute
28442 Main of the project file and -B is not specified. Do not skip bind/link
28443 steps when -B is specified.
28445 * makeusg.adb: Document new switch -B

28468 -gnatwa warning on static condition.
28470 2004-01-05 Doug Rupp <rupp@gnat.com>

28474 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
28476 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
28477 all attributes, including read-only attribute.

28482 library naming scheme.
28484 * mlib-prj.adb (Build_Library): Generate different names for the static
28485 or dynamic version of the GNAT runtime. This is needed to support the
28486 new shared library naming scheme.

28488 based on the new naming scheme.
28490 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
28491 scheme for the shared runtime libraries.
28494 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
28496 (install-gnatlib): Do not create symlinks for shared libraries.
28497 (gnatlib-shared-default): Idem.
28498 (gnatlib-shared-dual-win32): New target. Not used for now as the
28499 auto-import feature does not support arrays/records.
28500 (gnatlib-shared-win32): Do not create copy for the shared libraries.
28501 (gnatlib-shared-vms): Fix shared runtime libraries names.
28503 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
28504 dependent runtime shared library name.
28506 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
28508 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
28511 2004-01-05 Ed Schonberg <schonberg@gnat.com>
28513 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
28514 protected objects when allocator has a subtype indication, not a
28515 qualified expression. Note that qualified expressions may have to be
28516 checked when limited aggregates are implemented.
28518 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
28519 pure, emit warning.
28520 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
28521 subprogram is imported, remove warning.
28523 2004-01-05 Geert Bosch <bosch@gnat.com>
28525 * s-poosiz.adb: Update copyright notice.
28526 (Allocate): Use Task_Lock to protect against concurrent access.

28565 * cstand.adb (Create_Standard): Change the way how the declaration of
28566 the Duration type is created (making it the same way as it is for all
28567 the other standard types).
28569 2003-12-17 Robert Dewar <dewar@gnat.com>
28571 * s-crtl.ads: Fix header format
28572 Change Pure to Preelaborate

28576 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
28577 the expression type only if it is declared in the current unit.
28579 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
28580 are universal and already analyzed, as can occur in constrained
28581 subcomponents that depend on discriminants, when one constraint is a
28584 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
28585 type Any_Fixed is legal as the argument of a conversion, if only one
28586 fixed-point type is in context.

28599 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
28600 (Gnatchop): Do not set failure status when reporting the number of
28603 2003-12-15 Doug Rupp <rupp@gnat.com>

28627 2003-12-11 Ed Falis <falis@gnat.com>
28629 * 5zinit.adb: Clean up.
28631 * 5zintman.adb (Notify_Exception): replaced case statement with a call
28632 to __gnat_map_signal, imported from init.c to support
28633 signal -> exception mappings that depend on the vxWorks version.
28636 Created and exported __gnat_map_signal to support signal -> exception
28637 mapping that is dependent on the VxWorks version.
28638 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
28640 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

28666 Minor reformatting throughout
28668 2003-12-11 Ed Schonberg <schonberg@gnat.com>
28670 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
28671 bounds of a loop, create a separate block in order to generate proper
28672 cleanup actions to prevent memory leaks.
28674 * sem_res.adb (Resolve_Call): After a call to
28675 Establish_Transient_Scope, the call may be rewritten and relocated, in
28676 which case no further processing is needed.

28691 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
28694 2003-12-08 Robert Dewar <dewar@gnat.com>
28696 * 7sintman.adb: Minor reformatting
28698 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
28699 standard linker options to get standard libraries linked. We now plan
28700 to provide dummy versions of these libraries to match the appropriate
28701 configurable run-time (e.g. if a library is not needed at all, provide
28702 a dummy empty library).
28704 * targparm.ads: Configurable_Run_Time mode no longer affects linker
28705 options (-L parameters and standard libraries). What we plan to do is
28706 to provide dummy libraries where the libraries are not required.
28708 * gnatbind.adb: Minor comment improvement
28710 2003-12-08 Javier Miranda <miranda@gnat.com>
28712 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
28713 aggregate in the parent. Otherwise constants with limited aggregates
28714 are not supported. Add new formal to pass the component type (Ctype).
28715 It is required to call the corresponding IP subprogram in case of
28716 default initialized components.
28717 (Gen_Assign): In case of default-initialized component, generate a
28718 call to the IP subprogram associated with the component.
28719 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
28720 of aggregate with default initialized components.
28721 (Has_Default_Init_Comps): Improve implementation to recursively check
28722 all the present expressions.
28724 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
28725 to indicate that the initialization call corresponds to a
28726 default-initialized component of an aggregate.
28727 In case of default initialized aggregate with tasks this parameter is
28728 used to generate a null string (this is just a workaround that must be
28729 improved later). In case of discriminants, this parameter is used to
28730 generate a selected component node that gives access to the discriminant
28733 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
28734 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
28735 allocated aggregates with default-initialized components.
28737 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
28738 the box notation is used in positional aggregates.

28755 (Parse): New Boolean parameter Store_Comments, defaulted to False.
28756 Set the scanner to return ends of line and comments as tokens, if
28757 Store_Comments is True.
28758 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
28759 comments are associated with these nodes. Store the node IDs in the
28761 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
28763 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
28764 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
28765 current project. Call Tree.Restore afterwards. Set the various nodes
28766 for comment storage (Next_End, End_Of_Line, Previous_Line,
28769 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
28770 defaulted to False.
28772 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
28773 to False. When Truncated is True, truncate the string, never go to the
28775 (Write_End_Of_Line_Comment): New procedure
28776 (Print): Process comments for nodes N_With_Clause,
28777 N_Package_Declaration, N_String_Type_Declaration,
28778 N_Attribute_Declaration, N_Typed_Variable_Declaration,
28779 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
28780 Process nodes N_Comment.
28782 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
28783 without comments and there are some comments, set the flag
28784 Unkept_Comments to True.
28785 (Scan): If there are comments, set the flag Unkept_Comments to True and
28786 clear the comments.
28787 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
28788 (Next_End_Nodes: New table
28789 (Comment_Zones_Of): New function
28790 (Scan): New procedure; moved from Prj. Accumulate comments in the

28813 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
28814 defaulted to False.
28815 (Scan): Store position of start of comment. If comments are tokens, set
28816 Comment_Id and set Token to Tok_Comment when scanning a comment.
28817 (Set_Comment_As_Token): New procedure
28819 * sinput-p.adb: Update Copyright notice
28820 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
28821 that no longer exists.
28823 2003-12-08 Javier Miranda <miranda@gnat.com>
28825 * sem_aggr.adb: Add dependence on Exp_Tss package
28826 Correct typo in comment
28827 (Resolve_Aggregate): In case of array aggregates set the estimated
28828 type of the aggregate before calling resolve. This is needed to know
28829 the name of the corresponding IP in case of limited array aggregates.
28830 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
28831 in case of default initialized array components.
28833 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
28834 types. Required to give support to limited aggregates in generic
28837 2003-12-08 Ed Schonberg <schonberg@gnat.com>

28840 inlined body functions like an instantiation.
28841 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
28842 until bounds are analyzed, to diagnose premature use of type.
28844 * sem_util.adb (Wrong_Type): Improve error message when the type of
28845 the expression is used prematurely.
28847 2003-12-08 GNAT Script <nobody@gnat.com>
28849 * Make-lang.in: Makefile automatically updated
28851 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
28853 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
28854 they are automatically generated by Make-lang.in and cause nothing but
28855 maintenance troubles.
28857 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
28859 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

28868 Update copyright notice when appropriate.
28870 * 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
28873 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
28874 to ensure that the kernel fills in the interrupted context structure
28875 before calling a signal handler, which is necessary to be able to
28876 unwind past it. Update the copyright notice.
28878 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
28880 * a-elchha.ads: New file.
28882 * a-elchha.adb: New default last chance handler. Contents taken from
28883 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
28885 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine

30334 Remove the test against being in No_Run_Time_Mode before generating a
30335 call to Register_Tag. It is redundant with the test against the
30336 availability of the function Register_Tag.

32522 2002-01-30 Richard Henderson <rth@redhat.com>
32524 * trans.c (tree_transform) [N_Loop_Statement]: Use
32525 expand_exit_loop_top_cond.

32539 rule which was mandated by code generation issues.
32541 * gnat-style.texi (header): Add @dircategory, @direntry.
32542 (title page): Remove date.
32543 (general) Add @./@: where approriate, and two spaces after the
32544 full stop at the end of a sentence. Use @samp markup when
32545 referring concrete lexical entities (keywords, attribute names
32546 etc.), and @syntax for ARM grammar elements. Use @r for English
32547 text in comments. Use @emph for emphasis. Change "if-statements"
32548 etc. to "if statements" (without @samp). Break long lines. Make
32549 casing of section names consistent.
32550 (Identifiers): Use @samp markup for variable names.
32551 (Comments): Use @samp markup for comment characters. Line-end
32552 comments may follow any Ada code, not just statements. Fix
32553 misspelling of "Integer" as "integer".
32554 (Loop statements): Do not use variable name "I", use "J".

32562 function approach did not work well because of a side effect (the
32563 function call could reallocate the table which was being indexed
32564 using its result). Fixes ada/4851.

32931 2001-12-17 Laurent Pautet <pautet@gnat.com>
32934 Fix comment of Shutdown_Socket and Close_Socket. These functions
32935 should not fail silently because if they are called twice, this
32936 probably means that there is a race condition in the user program.
32937 Anyway, this behaviour is consistent with the rest of this unit.
32938 When an error occurs, an exception is raised with the error message
32939 as exception message.

34288 is what this variable will store.
34290 * bcheck.adb: Change reference to chechsum in comments by CRC.
34291 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
34292 rename All_Checksum_Match to All_CRC_Match. Change due to API
34293 renaming since now GNAT does not use a simple checksum but a
34294 CRC using GNAT.CRC32.
34296 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
34297 now and not anymore a simple checksum.
34299 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
34302 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
34305 (Restore_Scan_State): rename Checksum to CRC.
34306 (Save_Scan_State): idem.
34310 (Checksum): rename to CRC.
34311 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
34313 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
34314 GNAT.CRC32). Update copyright notice.
34316 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
34317 GNAT.CRC32). Update copyright notice.
34320 (Accumulate_Checksum): removed.
34321 (Update): new procedure. Add a wide-character into the CRC.

34334 Update comments for the CRC.
34336 * types.adb (Hex): Use lowercase for the letter part.
34338 * types.ads (Get_Hex_String): Returns the hexadecimal representation
34339 for a word. This is currently used only for CRC. In previous version,
34340 the checksum was using a representation with all letter being
34341 upper-case. With the new implementation (using CRC) we do not remove
34342 the 32th bit of the CRC, so we can have an upper-case starting letter
34343 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
34344 It is ambigous since the CRC was optional and could be followed by
34345 options like EB, EE. So now this routines uses lower-case letter for
34346 the hexadecimal representation. Strange enough only lower case letters
34347 where checked in Scan_ALI (even if this was not a possible case).
34349 * gnatvsn.ads (Library_Version): changed to 3.15a.
34351 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version

34361 * ali-util.ads: Redo changes of previous revision to continue to use
34362 the word Checksum. Add 2001 to copyright notice.
34364 * ali.adb: Undo some of previous changes, not needed.
34365 Keep the change for lower case letters in the checksum.
34367 * ali.ads: Undo previous change not needed.
34369 * bcheck.adb: Undo most of previous change, not needed.
34370 But do use Checksums_Match for checksum comparison.
