372 Exception_Information is used to produce useful debugging
373 information for the programmer. However, it was also used to
374 implement the stream attributes for type Exception_Occurrence. The
375 latter requires a stable and portable interface, which meant
376 that we couldn't include a symbolic traceback. A separate set of
377 routines was used to provide symbolic tracebacks under program
378 control (i.e. not automatically). The goal of this ticket is
379 to provide such automatic tracebacks, so the change here is to
380 split the two functionalities: Exception_Information gives the
381 maximally useful information for debugging (i.e. it now includes
382 a symbolic traceback when a decorator is set, and it can be
383 improved freely in the future without disturbing streaming).
384 Untailored_Exception_Information always uses hexadecimal addresses
385 in the traceback, has a stable and portable output, and is now

559 * Makefile.rtl, gnat_rm.texi, i-cpp.adb, i-cpp.ads, impunit.adb,
560 rtsfind.ads: Remove references to package Interfaces.CPP since this
561 package is no longer needed.
563 2014-07-30 Bob Duff <duff@adacore.com>
565 * s-taasde.adb (Timer_Queue): Don't use a
566 build-in-place function call to initialize the Timer_Queue.
567 * s-traent.adb, s-traent.ads, s-traent-vms.adb, s-traent-vms.ads:
568 Turn off polling in these units, because otherwise we get
569 elaboration circularities with Ada.Exceptions when the -gnatP
571 * s-tassta.adb (Create_Task): Make sure independent tasks
572 are created with Parent = Environment_Task. This was not true,
573 for example, in s-interr.adb, when Interrupt_Manager does "new
574 Server_Task"; the Server_Task had Parent = Interrupt_Manager,
575 which is wrong because the master is determined by the access
576 type, which is at library level.
577 * s-tasuti.adb (Make_Independent): Avoid setting Parent; it is
578 now set correctly by Create_Task.
579 (Make_Passive): Remove the workaround for the race condition in
581 * frontend.adb (Frontend): Revert to previous method of detecting
582 temporary configuration pragma files, recognizing such files by
583 ".tmp" in the name. This is more general than detecting pragmas
584 Source_File_Name_Project, because it allows any tool to use
585 this naming convention, no matter the content of the file.
586 * gnat_ugn.texi: Document this naming convention.
588 2014-07-30 Robert Dewar <dewar@adacore.com>

597 2014-07-30 Ed Schonberg <schonberg@adacore.com>
599 * sem_ch5.adb: Improve error recovery.
600 * inline.adb (Build_Body_To_Inline): Set Full_Analysis to false
601 before analyzing the body, so that in GNATprove mode there is
602 no light expansion. Whatever expansion is required by SPARK will
603 be performed when analysing the inlined code.
605 2014-07-30 Bob Duff <duff@adacore.com>
607 * s-tataat.adb, s-tataat.ads, a-tasatt.adb: Minor comment fixes.

617 * sem_ch8.adb (Push_Scope): Initialize Locked_Shared_Objects.
618 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Handle the case where
619 the call returns an unconstrained type: in this case there is
620 already a transient scope, and we should not establish a new one.
621 * exp_ch7.adb (Insert_Actions_In_Scope_Around): New formal Clean. If
622 True, also insert cleanup actions in the tree.
623 (Wrap_Transient_Declaration): Call Insert_Actions_In_Scope_Around
626 2014-07-30 Arnaud Charlet <charlet@adacore.com>

629 Direct_Attribute_Element, Direct_Attribute_Array,
630 Direct_Index_Vector, Direct_Attributes, Is_Defined,
631 Indirect_Attributes): Removed. (Atomic_Address,
632 Attribute_Array, Attributes): New.
633 * s-tasini.ads, s-tasini.adb (Proc_T, Initialize_Attributes,
634 Finalize_Attributes_Link, Initialize_Attributes_Link): Removed.
635 (Finalize_Attributes): Reimplement.
636 * s-tassta.adb (Create_Task): Remove call to
637 Initialize_Attributes_Link (Free_Task, Vulnerable_Free_Task):
638 Replace Finalize_Attributes_Link by Finalize_Attributes.
639 * a-tasatt.ads, a-tasatt.adb, s-tataat.ads, s-tataat.adb:
640 Reimplement from scratch, using a simpler and more efficient
642 * s-tporft.adb (Register_Foreign_Thread): Remove now obsolete comment.
643 * s-parame.ads, s-parame-hpux.ads,
644 * s-parame-vms-alpha.ads, s-parame-vms-ia64.ads,

646 Default_Attribute_Count.
648 2014-07-30 Olivier Hainque <hainque@adacore.com>
650 * vxworks-ppc-link.spec: New file. Extra link
651 instructions for ppc-vxworks.
652 * vxworks-crtbe-link.spec: Likewise, for ZCX related support.
653 * system-vxworks-ppc.ads: Adjust linker options to use spec files.
654 * system-vxworks-arm.ads: Likewise.
655 * gcc-interface/Makefile.in: Enable .spec files.
657 2014-07-30 Ed Schonberg <schonberg@adacore.com>
659 * sem_aggr.adb: Minor comment reformatting.
661 2014-07-30 Robert Dewar <dewar@adacore.com>

668 (Warn_On_Useless_Assignment): ditto.
670 2014-07-30 Ed Schonberg <schonberg@adacore.com>
672 * checks.adb (Insert_Valid_Check): Do not check for the packed
673 array type of a prefix that is an access type.
675 2014-07-30 Ed Schonberg <schonberg@adacore.com>
677 * sem_attr.adb (Eval_Attribute): Evaluate the GNAT attribute
678 Unconstrained_Array even if prefix is not frozen yet, as can
679 occur with a private subtype used as a generic actual.
681 2014-07-30 Gary Dismukes <dismukes@adacore.com>
683 * sem_attr.adb: Minor reformatting.
685 2014-07-30 Pat Rogers <rogers@adacore.com>
687 * gnat_rm.texi: Corrected minor wording error in description
688 of No_Exception_Registration.
690 2014-07-30 Yannick Moy <moy@adacore.com>
692 * einfo.ads, einfo.adb: New flag Is_Inlined_Always for use in GNATprove
693 mode. Realphabetize two subprograms.
694 * inline.adb (Cannot_Inline): Use Is_Inlined_Always in GNATprove mode.
695 (Can_Be_Inlined_In_GNATprove_Mode): Adapt to possible Empty Body_Id.
696 (Check_And_Build_Body_To_Inline): Use Is_Inlined_Always in GNATprove
698 (Expand_Inline_Call): Use Is_Inlined_Always in GNATprove mode.
699 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not use
700 Is_Inline in GNATprove mode.
701 (Analyze_Subprogram_Specification):
702 Set Is_Inlined_Always at subprogram entity creation.
703 * sem_res.adb (Resolve_Call): Do not deal with inlining during
704 pre-analysis. Issue warning on call to possibly inlined
705 subprogram when body not seen.
707 2014-07-30 Yannick Moy <moy@adacore.com>
709 * lib-xref.adb (Generate_Reference): Add special

724 2014-07-30 Thomas Quinot <quinot@adacore.com>
726 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
727 Bit_Order): Set Reverse_Bit_Order on the base type of the
728 specified first subtype.
730 2014-07-30 Ed Schonberg <schonberg@adacore.com>
732 * inline.adb (Expand_Inlined_Call): Use a renaming declaration
733 to capture the value of actuals of a limited type rather than
734 an object declaration, to prevent spurious errors when analyzing
737 2014-07-30 Ed Schonberg <schonberg@adacore.com>
739 * sem_ch4.adb (Analyze_Type_Conversion): Treat an inlined body
740 as an instance, and inhibit semantic checks on already analyzed
741 code to prevent spurious errors.
743 2014-07-30 Arnaud Charlet <charlet@adacore.com>
745 * a-exctra.ads ("="): New function, to restore compatibility.
747 2014-07-30 Pascal Obry <obry@adacore.com>
749 * adaint.c (__gnat_to_os_time): Set isdst to -1 for the mktime
750 routine to use the OS dst setting.
752 2014-07-30 Pat Rogers <rogers@adacore.com>
754 * gnat_ugn.texi: Minor correction to description of -gnatw.K.
756 2014-07-30 Ed Schonberg <schonberg@adacore.com>
758 * sem_util.adb (Wrong_Type): Disable some checks equally within
759 instances and within inlined bodies, to suppress spurious type
760 errors on already analyzed code.
761 * sem_aggr.adb (Check_Expr_OK_In_Limited_Aggregate): Expression
762 is legal in an inlined body, juts as it is in an instance body.
764 2014-07-30 Ed Schonberg <schonberg@adacore.com>
766 * sem_res.adb (Resolve_Unchecked_Conversion): Within an inlined
767 body the operand of an unchecked conversion may be a literal, in
768 which case its type is the target type of the conversion. This
769 is in contrast to conversions in other contexts, where the
770 operand cannot be a literal and must be resolvable independent
773 2014-07-30 Pierre-Marie Derodat <derodat@adacore.com>
775 * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Create a

779 * gcc-interface/gigi.h (renaming_from_generic_instantiation_p): New.
781 2014-07-30 Robert Dewar <dewar@adacore.com>
783 * s-tasuti.adb, s-tasuti.ads, einfo.ads, sem_prag.adb, s-taasde.adb,
784 g-socthi-vms.adb, s-taprop-mingw.adb, s-interr.adb, s-interr-hwint.adb,

787 g-awk.adb, gnatls.adb, s-taspri-posix.ads, g-catiio.adb,
788 s-interr-sigaction.adb, s-os_lib.adb, s-fileio.adb: Minor reformatting
789 & code reorganization.
791 2014-07-30 Bob Duff <duff@adacore.com>
793 * s-tassta.adb, sem_util.ads: Minor reformatting.
795 2014-07-30 Yannick Moy <moy@adacore.com>
797 * inline.adb (Build_Body_To_Inline): Detect when
798 subprogram has multiple returns, or not a single last return
799 statement, in GNATprove mode.
800 (Cannot_Inline): Simplify logic to handle case of GNATprove
803 2014-07-30 Ed Schonberg <schonberg@adacore.com>
805 * sem_ch6.adb: Stubs are not subject to inlining.
807 2014-07-30 Bob Duff <duff@adacore.com>
809 * s-tasuti.ads, s-tasuti.adb (Make_Independent): Change this
810 from a procedure to a function, so that it can more easily be
811 called before the "begin" of a task.
812 * s-taasde.ads (Delay_Block): Make this type immutably limited,
813 so we can use a build-in-place function call to initialize
814 Timer_Queue in the body.
815 * a-rttiev.adb, s-asthan-vms-alpha.adb, s-asthan-vms-ia64.adb,
816 * s-interr.adb, s-interr-hwint.adb, s-interr-sigaction.adb,
817 * s-interr-vms.adb, s-taasde.adb: Each independent task now calls
818 Make_Independent before reaching its "begin", to avoid race
819 conditions. This causes the activating task to wait until after
820 Make_Independent is complete before proceeding. In addition,
821 we initialize data structures used by independent tasks before
822 activating those tasks, to avoid possible use of uninitialized data.
823 * s-interr.ads, s-intman.ads, s-taspri-posix.ads, s-tasdeb.ads:
826 2014-07-30 Bob Duff <duff@adacore.com>
828 * a-exctra.ads, s-traent-vms.ads, s-traent.ads (Tracebacks_Array): Move
829 the declaration of Tracebacks_Array from Ada.Exceptions.Traceback to
830 System.Traceback_Entries (s-traent.ads and s-traent-vms.ads). Add
831 subtypes renaming Tracebacks_Array in Ada.Exceptions.Traceback.
832 * g-debpoo.adb: Refer to Tracebacks_Array in its new home.
834 2014-07-30 Arnaud Charlet <charlet@adacore.com>
836 * a-tasatt.adb: Remove old comments.
838 2014-07-30 Yannick Moy <moy@adacore.com>
840 * einfo.ads (Is_Inlined): Document new use in GNATprove mode.
841 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Add comments
842 to explain rationale for inlining or not in GNATprove mode.
843 (Expand_Inlined_Call): In GNATprove mode, set Is_Inlined flag
844 to False when inlining is not possible.
845 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Is_Inlined
846 flag to indicate that subprogram is fully inlined. To be reversed
847 if inlining problem is found.
848 * sem_res.adb (Resolve_Call): Set Is_Inlined flag to False when
849 call in potentially unevaluated context.
851 2014-07-30 Jose Ruiz <ruiz@adacore.com>
853 * s-tarest.adb, s-tarest.ads: Fix comments.
855 2014-07-30 Robert Dewar <dewar@adacore.com>
857 * exp_attr.adb, checks.adb, sem_util.adb, sem_util.ads, sem_attr.adb:
858 Change No_Scalar_Parts predicate to Scalar_Part_Present and
859 invert sense of test. This avoids the "not No_xxx" situation
860 which is always ugly.
862 2014-07-30 Ed Schonberg <schonberg@adacore.com>
864 * inline.adb (Expand_Inlined_Call): When generating code for
865 an internal subprogram the expansion uses the location of the
866 call, so that gdb can skip over it. In GNATprove mode we want to
867 preserve slocs of original subprogram when expanding an inlined
868 call, to obtain better warnings, even though subprogram appears
869 not to come from source if it is the inlining of a subprogram
870 body without a previous spec.
872 2014-07-30 Eric Botcazou <ebotcazou@adacore.com>
874 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Reject array
875 types with atomic components.
877 2014-07-30 Thomas Quinot <quinot@adacore.com>
879 * Make-generated.in: Remove now unnecessary targets after s-oscons
882 2014-07-30 Yannick Moy <moy@adacore.com>
884 * sem_res.adb (Resolve_Call): Use ultimate alias
885 of callee when available.
887 2014-07-30 Ed Schonberg <schonberg@adacore.com>
889 * sem_ch6.adb (Analyze_Expression_Function): To check whether
890 an expression function is a completion, use the specification of
891 the previous declaration, not its entity, which may be internally
892 generated in an inlined context.
894 2014-07-30 Doug Rupp <rupp@adacore.com>
896 * adaint.c (__gnat_tmp_name) [__ANDROID__]: Default to putting
897 temp files in /cache directory unless overridden by TMPDIR.
899 2014-07-30 Jose Ruiz <ruiz@adacore.com>
901 * s-tassta.adb, s-tarest.adb (Initialize, Create_Task,
902 Create_Restricted_Task): Remove redundant check. Number_Of_CPUs returns
903 type CPU, so it can never be greater than CPU_Range'Last.
905 2014-07-30 Bob Duff <duff@adacore.com>
907 * s-taskin.ads: Minor comment fix.
909 2014-07-30 Thomas Quinot <quinot@adacore.com>

924 generate the xoscons utility, in runtime-agnostic rules.
925 * gcc-interface/Makefile.in: Clean up rules. Remove VMS parts,
928 2014-07-30 Bob Duff <duff@adacore.com>
930 * exp_ch6.adb (Add_Task_Actuals_To_Build_In_Place_Call): New
931 parameter Chain to be used in the allocator case.
932 (Make_Build_In_Place_Call_In_Allocator): If the allocated object
933 has tasks, wrap the code in a block that will activate them,
934 including the usual finalization code to kill them off in case
935 of exception or abort.
937 2014-07-30 Robert Dewar <dewar@adacore.com>
939 * treepr.adb, treepr.ads; Reorganize documentation for new pp routines
940 Remove renamings (don't work for gdb).
941 (par): New synonym for p (avoid gdb ambiguities).
942 * inline.adb, sem_ch6.adb, sem_ch13.adb: Minor reformatting.

961 of predicate aspect on entity other than a type.
963 2014-07-30 Ed Schonberg <schonberg@adacore.com>
965 * sem_ch6.adb (Body_Has_Contract): New predicate to determine
966 when a subprogram body without a previous spec cannot be inlined
967 in GNATprove mode, because it includes aspects or pragmas that
968 generate a SPARK contract clause.
969 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): A subprogram
970 instance cannot be inlined.
972 2014-07-30 Robert Dewar <dewar@adacore.com>
974 * debug.adb: Document that d7 suppresses compilation time output.

998 * par-ch4.adb (Is_Parameterless_Attribute): 'Result is a
999 parameterless attribute, and a postondition can mention an
1000 indexed component or a slice whose prefix is an attribute
1003 2014-07-30 Robert Dewar <dewar@adacore.com>
1005 * sprint.adb (Sprint_Node_Actual, case Object_Declaration):
1006 Avoid bomb when printing package Standard.
1008 2014-07-30 Ed Schonberg <schonberg@adacore.com>
1010 * sem_elab.adb (Check_Internal_Call_Continue): If an elaboration
1011 entity is created at this point, ensure that the name of the
1012 flag is unique, because the subprogram may be overloaded and
1013 other homonyms may also have elaboration flags created on the fly.
1015 2014-07-30 Hristian Kirtchev <kirtchev@adacore.com>
1017 * sem_attr.adb (Analyze_Array_Component_Update): New routine.
1018 (Analyze_Attribute): Major cleanup of attribute
1019 'Update. The logic is now split into two distinct routines

1022 (Analyze_Record_Component_Update): New routine.
1023 (Check_Component_Reference): Removed.
1024 (Resolve_Attribute): Remove the return statement and ??? comment
1025 following the processing for attribute 'Update. As a result,
1026 the attribute now freezes its prefix.

1052 not delayed. Update the delay status of most SPARK 2014 aspects.
1053 * sem_ch13.adb (Analyze_Aspect_Specifications): Update all calls
1054 to Decorate_Aspect_And_Pragma and Insert_Delayed_Pragma to refert
1055 to Decorate and Insert_Pragma. Add various comments concerning
1056 the delay status of several SPARK 2014 aspects. The insertion
1057 of Refined_State now uses routine Insert_After_SPARK_Mode.
1058 (Decorate): New routine.
1059 (Decorate_Aspect_And_Pragma): Removed.
1060 (Insert_Delayed_Pragma): Removed.
1061 (Insert_Pragma): New routine.

1394 * sem_ch3.adb (Constrain_Corresponding_Record): For the case
1395 of the subtype created for a record component, do not mark
1396 the subtype as frozen. For one thing, this is anomalous (in
1397 particular, the base type might not itself be frozen yet);
1398 furthermore, proper freezing of the subtype must happen in any
1399 case. So, we just mark the subtype as requiring delayed freezing
1400 (and we'll actually freeze it when generating the init_proc of
1401 the enclosing record).
1402 Also change the name of the constrained record subtype (append a
1403 'C' so that it is clearly different from the unconstrained record
1404 type, "related_idV") to make debugging easier.
1405 (Process_Full_View): When creating a full subtype for a pending

1529 is a completion of a declaration in the same declarative part,
1530 and the subprogram has had its address taken, add elaboration

7387 several routines out to avoid deep nesting and indentation.
7388 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
7389 parameter Do_Checks to Post_Errors. Update the comment on usage.

7563 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
7564 just direct dependents. If this is actually an abort, each task

7567 time from Vulnerable_Complete_Master "for convenience" (i.e. to
7568 kill off tasks waiting at terminate alternatives), aborting
7569 indirect dependents is wrong, because it causes some unrelated
