278 to libgnat subdirectory.
280 2017-09-08 Yannick Moy <moy@adacore.com>
282 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
283 return the entity associated with the call.
284 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
285 Replace the internal Get_Function_Id with the new
286 Sem_Aux.Get_Called_Entity.
287 (Iterate_Call_Parameters): New
288 procedure to iterate on formals and actuals at the same time.
289 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
290 Set SPARK_Mode from spec when set, for analysis
291 of instance. Restore after analysis of instance.
292 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
293 set, for analysis of body instance. Restored automatically at
294 the end of the subprogram.
295 * gnat1drv.adb (Adjust_Global_Switches): Set
296 Check_Validity_Of_Parameters to False in GNATprove mode.
297 * opt.ads (Check_Validity_Of_Parameters): Document switch to
300 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
302 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
303 (New_Copy_Tree): ...there. Reset the hash tables only if they
304 were used in the previous invocation.
305 * s-htable.adb: Fix typo.
307 2017-09-08 Bob Duff <duff@adacore.com>
309 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
311 2017-09-08 Arnaud Charlet <charlet@adacore.com>
313 * sem_aggr.adb: minor style fix.
315 2017-09-08 Bob Duff <duff@adacore.com>
317 * sprint.adb (Write_Corresponding_Source): Ignore if there is
318 no current source file.
319 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
320 Print something helpful in case N is invalid.
321 * sprint.ads: Minor comment fix.
323 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
325 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
328 2017-09-08 Bob Duff <duff@adacore.com>
330 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
331 Ada_2020, along the same lines as the other Ada version pragmas.
333 2017-09-08 Gary Dismukes <dismukes@adacore.com>
335 * sem_ch12.adb: Minor typo fixes and reformatting.
337 2017-09-08 Yannick Moy <moy@adacore.com>
339 * sem_aggr.adb (Resolve_Record_Aggregate):
340 Rewrite bounds of aggregate subexpressions which may depend on
341 discriminants of the enclosing aggregate.
343 2017-09-08 Yannick Moy <moy@adacore.com>
345 * sem_ch5.adb: Prevent assertion failure on illegal code.
347 2017-09-08 Yannick Moy <moy@adacore.com>
349 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
350 calling Renamed_Entity on an entity which cannot be a renaming.
352 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
354 * exp_aggr.adb: Add with & use clause for Urealp.
355 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
356 elementary types instead of just discrete types.
357 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
358 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
359 Be prepared for the FP zero value in the memset case. Add small
362 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
364 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
367 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
369 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
370 of New_Copy because the latter leaves the syntactic structure of
371 the tree inconsistent (a child is accessible through two parents)
372 and prevents proper replication of itypes by subsequent calls
374 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
375 New_Copy because the latter leaves the syntactic structure of the
376 tree inconsistent (a child is accessible through two parents)
377 and prevents proper replication of itypes by subsequent calls
379 * sem_util.adb (In_Subtree): New routine.
380 (New_Copy_Tree): Reimplemented.
381 * sem_util.ads (In_Subtree): New routine.

384 2017-09-08 Ed Schonberg <schonberg@adacore.com>
386 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
387 for aspect Default_Value is a static scalar value, but it does
388 not freeze the type. Yhis allows for subsequent representation
389 clauses for the type.
391 2017-09-08 Javier Miranda <miranda@adacore.com>
393 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
394 not add entries into the undefined reference table when we are
395 compiling with errors ignored.
397 2017-09-08 Ed Schonberg <schonberg@adacore.com>
399 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
400 check if the instance is within an enclosing instance body. The
401 formal package was legal in the enclosing generic, and is
402 legal in the enclosing instantiation. This optimisation may be
403 applicable elsewhere, and it also removes spurious errors that
404 may arise with on-the-fly processing of instantiations that
405 contain Inline_Always subprograms.
407 2017-09-08 Vincent Celier <celier@adacore.com>
409 * gnatcmd.adb: Disregard empty argument of GNAT driver.
411 2017-09-08 Justin Squirek <squirek@adacore.com>
413 * checks.adb (Insert_Valid_Check): Manually decorate
414 the generated temporary for range valdity checks.
416 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
418 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
420 2017-09-08 Justin Squirek <squirek@adacore.com>
422 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
423 case to handle underscore flags.
424 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
425 new procedure to handle underscores.
427 2017-09-08 Javier Miranda <miranda@adacore.com>
429 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
430 divisions with fixed point results to avoid generating twice
431 the runtime check on divide by zero.
432 * checks.adb (Apply_Divide_Checks): Ensure that operands are
433 not evaluated twice (once for their runtime checks and once for
434 their regular computation).
436 2017-09-08 Yannick Moy <moy@adacore.com>
438 * sem_prag.adb (Analyze_Part_Of): Add missing
439 return statements after issuing errors. Add detection of
440 out-of-order item and single concurrent type.

542 * gcc-interface/Makefile.in: Enable s-trasym-dwarf.adb on x86*linux.
544 2017-09-08 Bob Duff <duff@adacore.com>
546 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
547 New routine to read the Tag robustly.
548 * exp_attr.adb (Input): Change the expansion of 'Input,
549 in the class-wide case, to call String_Input_Tag instead of
552 2017-09-08 Arnaud Charlet <charlet@adacore.com>
554 * s-rident.ads (Restriction_Id): reorder enum
555 literals, so that Pure_Barriers is no longer in range of the
556 Cunit_Boolean_Restrictions subtype.
558 2017-09-08 Nicolas Roche <roche@adacore.com>
560 * a-taster.ads, a-taster.adb: Move to libgnarl
561 * gcc-interface/Makefile.in: Remove obsolete targets. Code cleanups.
562 Add support for files in libgnarl.

566 * exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
567 accessibility check to an interface conversion, whose purpose
568 is to perform a pointer adjustment in a dispatching call.
569 * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
570 when the actual is a construct that involves a dereference of an
571 expression that includes a formal of the enclosing subprogram,
572 In such cases, the accessibility level of the actual is that of
573 the corresponding formal, which is passed in as an additional
574 actual in the outer call.
576 2017-09-08 Bob Duff <duff@adacore.com>
578 * exp_intr.adb (Add_Source_Info): Do not decode
579 file names; they were not encoded in the first place.
581 2017-09-08 Bob Duff <duff@adacore.com>
583 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
584 exceptions instead of crashes. Check for absurdly long strings
585 and empty strings. Empty strings cause trouble because they can
586 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
587 be empty, which causes an array index out of bounds.
588 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
591 2017-09-08 Arnaud Charlet <charlet@adacore.com>
593 * sem_util.adb (Is_CCT_Instance): allow use in
594 the context of protected types.

610 2017-09-08 Yannick Moy <moy@adacore.com>
612 * exp_attr.adb (Expand_Loop_Entry_Attribute): Do
613 not skip a loop coming from source which is rewritten into a loop.
615 2017-09-08 Ed Schonberg <schonberg@adacore.com>
617 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
618 wrapper has convention Ada, to prevent spurious warnings on
619 unconstrained array parameters.
621 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
623 * sem_prag.adb (Check_Variant): Use First_Non_Pragma/Next_Non_Pragma.

642 changes for Include_Subprogram_In_Messages.
643 * sem_ch5.adb (Check_Unreachable_Code): Supply Node parameter when
644 generating warning message.
646 2017-09-08 Ed Schonberg <schonberg@adacore.com>
648 * par-ch4.adb (P_Iterated_Component_Association): Place construct
649 under -gnat2020 flag, given that it is a future feature of
651 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
652 defining identifier as referenced to prevent spurious warnings:
653 corresponding loop is expanded into one or more loops whose
654 variable has the same name, and the expression uses those names
655 and not the original one.
657 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
659 * sem_elab.adb (Check_A_Call): Do not consider
660 references to internal variables for SPARK semantics.

664 * inline.adb (In_Package_Spec): refine type of
665 the parameter from Node_Id to Entity_Id.
667 2017-09-08 Justin Squirek <squirek@adacore.com>
669 * exp_ch5.adb (Expand_Formal_Container_Loop):

679 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
681 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
682 Correction of the return type from access type to option type.
683 (Simple_HTable): Moving the Instance_Data to ads file.
685 2017-09-08 Yannick Moy <moy@adacore.com>
687 * sem_prag.adb: Use System.Case_Util.To_Lower to simplify code.

709 * exp_ch6.adb (Unqual_BIP_Function_Call): Adding
710 missing checks on the presence of Entity() before checking the
713 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
715 * sem_ch6.adb (Analyze_Expression_Function): Reorder some
716 statements, use local variable and remove unnecessary processing.
718 2017-09-08 Javier Miranda <miranda@adacore.com>
720 * exp_ch6.ads (Make_Build_In_Place_Iface_Call_In_Allocator): New
722 (Make_Build_In_Place_Iface_Call_In_Anonymous_Context): New subprogram.

726 * exp_ch6.adb (Replace_Renaming_Declaration_Id): New
727 subprogram containing code that was previously inside
728 Make_Build_In_Place_Call_In_Object_Declaration since it is also
729 required for one of the new subprograms.
731 Invoke Make_Build_In_Place_Iface_Call_In_Anonymous_Context
732 (Expand_N_Extended_Return_Statement): Extend the
733 cases covered by an assertion on expected BIP object
735 (Make_Build_In_Place_Call_In_Assignment):
736 Removing unused code; found working on this ticket.
737 (Make_Build_In_Place_Call_In_Object_Declaration): Move the code
738 that replaces the internal name of the renaming declaration
739 into the new subprogram Replace_Renaming_Declaration_Id.

745 (Unqual_BIP_Iface_Function_Call): New subprogram.
746 * exp_ch3.adb (Expand_N_Object_Declaration): Invoke the new
747 subprogram Make_Build_In_Place_Iface_Call_In_Object_Declaration.
748 * exp_attr.adb (Expand_N_Attribute_Reference): Invoke the new
749 subprogram Make_Build_In_Place_Iface_Call_In_Anonymous_Context.
750 * exp_ch4.adb (Expand_Allocator_Expression): Invoke the new

762 2017-09-08 Javier Miranda <miranda@adacore.com>
764 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
765 access to interface types. Remove also the accessibility check.
767 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
769 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
770 all the types that are referenced by the expression.
771 (Analyze_Expression_Function): Call Freeze_Expr_Types for
772 a completion instead of manually freezing the type of the
774 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
776 2017-09-08 Ed Schonberg <schonberg@adacore.com>
778 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
779 New procedure, auxiliary to Expand_Pragma_Check, to handle
780 references to the discriminants of a protected type within a
781 precondition of a protected operation. This is needed because
782 the original precondition has been analyzed in the context of
783 the protected declaration, but in the body of the operation
784 references to the discriminants have been replaved by references
785 to the discriminants of the target object, and these references
786 are only created when expanding the protected body.
788 2017-09-08 Yannick Moy <moy@adacore.com>
790 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
793 2017-09-08 Ed Schonberg <schonberg@adacore.com>
795 * exp_attr.adb (Build_Record_VS_Func): If the record is an
796 unchecked union, do not emit checks for its (non-existent)
797 discriminants, or for variant parts that depend on them.
799 2017-09-08 Justin Squirek <squirek@adacore.com>
801 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
802 Find_Comparison_Type.Try_One_Interp): Add check for generic
805 2017-09-08 Arnaud Charlet <charlet@adacore.com>

808 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
809 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
810 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
811 remaining references to AAMP_On_Target.
813 2017-09-08 Ed Schonberg <schonberg@adacore.com>

822 interfaces using the underlying type to handle limited-withed
824 (Attribute_Tag): Check class-wide type interfaces using
825 the underlying type to handle limited-withed types.
827 2017-09-08 Ed Schonberg <schonberg@adacore.com>
829 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
830 over a subtype of a type with a static predicate, taking into
831 account the predicate function of the parent type and the bounds
832 given in the loop specification.
833 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
834 a loop specification that is a subtype indication whose type mark
835 is a type with a static predicate, inherit predicate function,
836 used to build case statement for rewritten loop.
838 2017-09-08 Justin Squirek <squirek@adacore.com>
840 * lib-load.adb: Modify printing of error message to exclude file
843 2017-09-08 Arnaud Charlet <charlet@adacore.com>
845 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
846 don't inline subprograms declared in both visible and private
848 (In_Package_Spec): previously In_Package_Visible_Spec; now
849 detects subprograms declared both in visible and private parts
852 2017-09-08 Ed Schonberg <schonberg@adacore.com>
854 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
855 the type is an anonymous array in an object declaration, whose
856 component type has an invariant, use the object declaration
857 as the insertion point for the invariant procedure, given that
858 there is no explicit type declaration for an anonymous array type.
860 2017-09-08 Bob Duff <duff@adacore.com>
862 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
864 2017-09-08 Bob Duff <duff@adacore.com>
866 * a-strfix.adb (Trim): Compute Low and High only if needed.
868 2017-09-08 Justin Squirek <squirek@adacore.com>
870 * lib-load.adb (Load_Main_Source): Add error output in the case a
871 source file is missing.
873 2017-09-08 Bob Duff <duff@adacore.com>
876 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
877 Default_WCEM by default (i.e. if the encoding is not specified
880 2017-09-08 Bob Duff <duff@adacore.com>
882 * s-trasym.ads (Hexa_Traceback): If
883 Suppress_Hex is True, print "..." instead of a hexadecimal
885 * s-trasym.adb: Ignore No_Hex in this version.
888 2017-09-08 Bob Duff <duff@adacore.com>
890 * debug.adb: Minor reformatting.
892 2017-09-08 Bob Duff <duff@adacore.com>
894 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
895 code so it doesn't trigger an "uninit var" warning.
897 2017-09-08 Nicolas Roche <roche@adacore.com>
899 * s-hibaen.ads: Remove obsolete file.
901 2017-09-08 Arnaud Charlet <charlet@adacore.com>
903 * a-locale.ads: Add comment explaining the state of this package.
905 2017-09-08 Arnaud Charlet <charlet@adacore.com>
907 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
909 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
910 allow calls in the context of package spec (for pragma
911 Initializes) and bodies (for pragma Refined_State).
913 2017-09-08 Bob Duff <duff@adacore.com>
915 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
918 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
920 * debug.adb (dA): Adjust comment.
921 * gnat1drv.adb (Gnat1drv): Likewise.
922 * opt.ads (List_Representation_Info_Extended): New variable.
923 * repinfo.adb (List_Record_Info): Split implementation into...
924 (Compute_Max_Length): ...this. Recurse on records if requested.
925 (List_Record_Layout): Likewise.
926 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
927 statement, accept '0' and set List_Representation_Info_Extended
929 * usage.adb (Usage): Document new -gnatRe variant.
931 2017-09-08 Ed Schonberg <schonberg@adacore.com>
933 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
934 Do not save the given entity in the global variable Default_Pool
935 if the pragma appears within a generic unit.
937 2017-09-08 Bob Duff <duff@adacore.com>
939 * errout.adb (Delete_Warning): Do not
940 decrement Warnings_Treated_As_Errors. This is called before
941 Warnings_Treated_As_Errors has been incremented to account for
942 this warning. Decrementing it here can lead to negative values
943 of Warnings_Treated_As_Errors, raising Constraint_Error in
944 checks-on builds, and causing the compiler to return an error
945 code in checks-off builds.
947 2017-09-08 Arnaud Charlet <charlet@adacore.com>
949 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
950 entities of named concurrent types as Ref_Id and not of anonymous
951 concurrent objects (because callers already know when a conversion
952 is necessary and can easily do it); also, do not expect protected
953 types or protected objects as Context_Id (because no flow-related
954 SPARK pragmas are attached there); reflect these changes in a
955 more precise comment.
957 2017-09-08 Olivier Hainque <hainque@adacore.com>
959 * g-altive.ads: Add documentation.
961 2017-09-08 Bob Duff <duff@adacore.com>
963 * sem_util.ads, debug.adb: Minor comment fix.
964 * erroutc.ads: Comment fix.
966 2017-09-08 Ed Schonberg <schonberg@adacore.com>
968 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
969 for compatibility of component types of formal and actual in an
970 instantiation of a child unit, when the component type of the
971 formal is itself a formal of an enclosing generic.
973 2017-09-08 Arnaud Charlet <charlet@adacore.com>
975 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
976 sem_prag.adb to make it available for GNATprove; for concurrent
977 types replace custom scope climbing with Scope_Same_Or_Within; for
978 single concurrent objects add scope climbing (with Scope_Within),
979 which was not there (that's the primary semantic change of this
980 commit); also, when comparing a single concurrent object with
981 its corresponding concurrent type rely on equality of types,
982 not of objects (because that's simpler to code).
983 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
984 (Analyze_Global_Item): adjust special-casing of references to the
985 current instance of a concurrent unit in the Global contracts
986 of task types and single tasks objects; similar for references
987 in the protected operations and entries of protected types and
988 single protected objects (in all these cases the current instance
989 behaves as an implicit parameter and must not be mentioned in
990 the Global contract).
992 2017-09-08 Arnaud Charlet <charlet@adacore.com>
994 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
995 function calls returning a record within a subprogram call,
998 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1000 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1001 name that designates the current instance of a child unit in its
1002 own body and appears as the prefix of a reference to an entity
1003 local to the child unit.
1004 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
1007 2017-09-08 Yannick Moy <moy@adacore.com>
1009 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
1012 2017-09-08 Tristan Gingold <gingold@adacore.com>
1014 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
1015 warnings on internal units in configurable run time mode.
1017 2017-09-08 Bob Duff <duff@adacore.com>
1019 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
1020 representation items from interfaces that the derived type
1021 implements, not just from the parent type.
1022 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
1023 this to return an empty list when there are no interfaces.
1024 * einfo.ads, sem_ch13.adb: Minor comment fixes.
1025 * sem_attr.adb: Minor comment fix.
1027 2017-09-08 Doug Rupp <rupp@adacore.com>

1032 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1034 * exp_ch4.adb (Expand_N_Allocator): Generate a
1035 call to Allocate_Any_Controlled when the allocation does not
1036 require any initialization.
1038 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1040 * sem_util.adb (Copy_Node_With_Replacement):
1041 Update the Renamed_Object field of a replicated object renaming
1044 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
1046 * exp_ch9.adb (Is_Pure_Barrier): Allow type
1047 conversions and components of objects. Simplified the detection
1048 of the Count attribute by identifying the corresponding run-time
1051 2017-09-08 Yannick Moy <moy@adacore.com>
1053 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
1054 sem_type.adb, sinfo.ads: Minor reformatting.
1056 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1058 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
1059 of Freeze_Profile, used to inhibit the freezing of the profile
1060 of an expression function declared within a nested package, when
1061 some type in the profile depends on a private type declared in
1062 an enclosing package.
1064 2017-09-08 Bob Duff <duff@adacore.com>
1066 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in

1598 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1600 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1601 entity of a mutable type and the right-hand side is a conditional
1602 expression, resolve the alternatives of the conditional using
1603 the base type of the target entity, because the alternatives
1604 may have distinct subtypes. This is particularly relevant if
1605 the alternatives are aggregates.
1607 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1609 * checks.adb (Apply_Predicate_Check): If the expression is an
1610 aggregate that is the RHS of an assignment, apply the check to
1611 the LHS after the assignment, rather than to the aggregate. This
1612 is more efficient than creating a temporary for the aggregate,
1613 and prevents back-end crashes when the aggregate includes a
1614 dynamic "others' association.
1616 2017-09-06 Yannick Moy <moy@adacore.com>
1618 * sem_ch12.adb (Analyze_Instance_And_Renamings):
1619 Set variable to ignore SPARK_Mode in instance before the analysis
1620 of the generated package declaration.
1622 2017-09-06 Yannick Moy <moy@adacore.com>
1624 * sem_res.adb (Resolve_Call): Do not issue a
1625 message for calls inside expression function, unless body was
1626 seen and is candidate for inlining.
1628 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1630 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
1631 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
1632 body. do not freeze the formals of the generic unit.
1634 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1636 * errout.adb (Error_Msg): Separate the
1637 treatment for warning vs. style messages in inlinings and
1638 instantiations. Prevents blowups on calls to Warn_Insertion for
1639 style messages, which should not be called in that case because
1640 Warning_Msg_Char is not set.
1642 2017-09-06 Justin Squirek <squirek@adacore.com>
1644 * sem_prag.adb (Check_VFA_Conflicts): Created
1645 to group all Volatile_Full_Access checks relating to other
1646 representation pragmas (Mark_Component_Or_Object): Created
1647 to centeralize the flagging of attributes for the record type
1648 component case, a pragma applied individually to a component, and
1650 (Process_Atomic_Independent_Shared_Volatile):
1651 Add propagation of certain pragmas to record components and move
1652 evaluation of VFA checks

1656 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
1657 Do not warn on conditions that are not obeyed for Inline_Always
1658 subprograms, when assertions are not enabled.
1660 2017-09-06 Arnaud Charlet <charlet@adacore.com>
1662 * sem_util.adb (Unique_Entity): For abstract states return their
1665 2017-09-06 Bob Duff <duff@adacore.com>
1667 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1668 that is a proper body corresponding to a stub, we defer the
1669 adjustment of the sloc until after the correct adjustment has
1670 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1671 the adjustment, because it will be outside the range in (the old,
1672 incorrect) S_Adjustment.
1673 * inline.adb: Use named notation for readability and uniformity.
1674 * sinput-l.adb: Minor improvements to debugging output printed
1676 * sinput-l.ads (Create_Instantiation_Source): Minor comment
1679 2017-09-06 Vincent Celier <celier@adacore.com>
1681 * make.adb: Do not invoke gprbuild for -bargs -P.
1683 2017-09-06 Sylvain Dailler <dailler@adacore.com>
1685 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
1686 case when Op is of kind N_Qualified_Expression. In this case,
1687 the function is called recursively on the subexpression like in
1689 * make.adb: Minor reformatting
1691 2017-09-06 Justin Squirek <squirek@adacore.com>
1693 * einfo.adb (Set_Linker_Section_Pragma): Modify
1694 Set_Linker_Section_Pragma to be consistant with the "getter"
1695 Linker_Section_Pragma.
1696 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1697 checking for container loops so that the index cursor is not
1698 directly changable by the user with the use of E_Loop_Parameter.
1699 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
1700 * sem_warn.adb (Check_References): Revert previous change.
1702 2017-09-06 Bob Duff <duff@adacore.com>

1709 * sem_prag.adb (Analyze_Depends_Global): Reinforce test on object
1710 declarations to only consider valid uses of Global/Depends those on
1711 single concurrent objects.

1732 * make.adb, makeusg.adb, switch-m.adb, switch-m.ads, make_util.adb,
1733 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
1734 gnatname.adb: Remove the Project Manager from the GNAT tools.
1735 * gcc-interface/Makefile.in: ditto.
1737 2017-09-06 Bob Duff <duff@adacore.com>
1739 * sem_util.ads: Minor comment fix.
1741 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1743 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
1744 Generate a freeze node for the actual of a formal package, if
1745 the actual is declared in the same unit and has a corresponding
1746 body, to prevent the current instance from being frozen before
1749 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1751 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.
1753 2017-09-06 Yannick Moy <moy@adacore.com>

1768 * exp_util.adb (Is_Controlled_Indexing): New routine.
1769 (Is_Displace_Call): Use routine Strip to remove indirections.
1770 (Is_Displacement_Of_Object_Or_Function_Result): Code clean up. Add a
1771 missing case of controlled generalized indexing.
1772 (Is_Source_Object): Use routine Strip to remove indirections.
1773 (Strip): New routine.
1775 2017-09-06 Bob Duff <duff@adacore.com>
1777 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1778 we include the proper header. Otherwise, we just declare the necessary
1779 things from the capabilities library. This is so we can build on
1780 machines without that library, while still enabling that library.
1781 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1782 simply return 0 if the library is not present, or not included
1785 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
1787 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

1798 has no parameter specification and no entry index, use the entry name
1799 as the end of the generated SCO statement.
1801 2017-09-06 Steve Baird <baird@adacore.com>
1803 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1804 uses of 'Image and related attributes as having side effects in
1805 order to avoid replicating such uses.
1806 * pprint.ads (Expression_Image) Add new generic formal flag
1807 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1808 (eventually) override the default.
1809 * pprint.adb (Expression_Image) If the new flag is set, then
1810 suppress the ".all" suffix when displaying a dereference whose
1811 prefix is a use of a value-capturing compiler temp of the sort
1812 generated by Expr_Util.Remove_Side_Effects .
1813 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

1828 so that applies to any entity.
1830 2017-09-06 Yannick Moy <moy@adacore.com>
1832 * sem_ch3.adb (Derived_Type_Declaration): Use
1833 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1835 2017-09-06 Javier Miranda <miranda@adacore.com>
1837 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1840 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1842 * sem_dim.adb (Analyze_Dimension): In an instance, a type

1845 (Dimensions_Of_Operand): Ditto.
1847 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1849 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

1870 2017-09-06 Yannick Moy <moy@adacore.com>
1872 * freeze.adb (Check_Inherited_Conditions): Rewriting
1873 of inherited preconditions and postconditions should only occur
1874 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1875 be confused with SPARK_Mode being On.

1893 (Entity_Hash): New function.
1894 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1895 (Is_Subprogram_Ref): Rename into...
1896 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1897 the table instead of bailing out on them. Scan the value of constants
1898 if it is not known at compile time.
1899 (Contains_Subprograms_Refs): Rename into...
1900 (Scan_Subprogram_Refs): ...this.
1901 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1902 Is_Public flag on subprograms if they are not actually referenced.
1903 (Hide_Public_Entities): Beef up comment on the algorithm.
1904 Reset the table of subprograms on entry.
1906 2017-09-06 Yannick Moy <moy@adacore.com>

1960 2017-09-06 Bob Duff <duff@adacore.com>
1962 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint

1991 * sem_type.adb (Interface_Present_In_Ancestor): Within an
1992 expression function, or within a spec expression (default value,

2013 Move Ada.Command_Line.Response_File to System.Response_File,
2014 and make Ada.Command_Line.Response_File into a rename of
2015 System.Response_File. This is to avoid having gnatbind depend
2016 Ada.Command_Line, which would damage the bootstrap process now
2017 that Ada.Command_Line contains modern Ada (the raise expression).
2018 * gnatbind.adb: Avoid dependence on
2019 Ada.Command_Line. Depend on System.Response_File instead
2020 of Ada.Command_Line.Response_File. Change one call to
2021 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2022 to Ada.Command_Line.Argument_Count to use Arg_Count.

2037 2017-09-06 Yannick Moy <moy@adacore.com>
2039 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

2048 (Write_Field15_Name): Update the output for
2049 Status_Flag_Or_Transient_Decl.
2050 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
2051 to loop parameters. Update the documentation of the attribute
2052 and the E_Loop_Parameter entity.
2053 * exp_ch7.adb (Process_Declarations): Remove the bogus guard
2054 which assumes that cursors can never be controlled.
2055 * exp_util.adb (Requires_Cleanup_Actions): Remove the bogus

2161 left-hand side, which are invisible in the righ-hand side and
2162 not retrievable as selected components.
2164 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2166 * sem_util.adb (Needs_One_Formal): The first formal of such a

2205 constraint for it, given that the constrained discriminants are
2206 not visible in the object.
2207 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2208 side may be derived from that of the left-hand side (as in the
2209 case of an assignment with a change of representation) so the
2210 discriminant to be used in the retrieval of the value of the
2211 component must be the entity in the type of the right-hand side.

2240 in a set membership is an overloaded enumeration literal, and
2241 the type of the alternative is resolved from a previous one,
2242 replace the entity of the alternative as well as the type,
2243 to prevent inconsistencies between the entity and the type.

2786 * exp_ch6.adb (Expand_Call_Helper): When locating the
2787 accessibility entity created for an access parameter, handle
2788 properly a reference to a formal of an enclosing subprogram. if
2789 the reference appears in an inherited class-wide condition, it
2790 is the rewriting of the reference in the ancestor expression,
2791 but the accessibility entity must be that of the current formal.
2793 2017-05-02 Javier Miranda <miranda@adacore.com>
2795 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

2831 procedure body for a local (sub)type declaration within a
2832 predicate function. Invariant checks do not apply to these, and
2833 the expansion of the procedure will happen in the wrong scope,
2834 leading to misplaced freeze nodes.
2836 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2838 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2839 to analyze generated actions. If the main unit is a body,

2875 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2876 Refine predicate for the case where the primitive operation
2877 is a renaming of equality. An overriding operation that is
2878 a user-defined renaming of predefined equality inherits its
2879 slot from the overridden operation. Otherwise it is treated
2880 as a predefined op and occupies the same predefined slot as
2881 equality. A call to it is transformed into a call to its alias,
2882 which is the predefined equality. A dispatching call thus uses
2883 the proper slot if operation is further inherited and called
2884 with class-wide arguments.
2886 2017-05-02 Justin Squirek <squirek@adacore.com>
2888 * errout.adb (Set_Msg_Text): Add a case to switch the message

2926 controlled components that has a trivial Initialize procedure,
2927 insert declaration for finalization counter after object

2931 a trivial Initialize procedure.

2965 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
2966 parameter Array_Comp to indicate the case of an array object
2967 with null-excluding components.
2968 * checks.adb (Null_Exclusion_Static_Checks):
2969 Call Compile_Time_Constraint_Error instead of
2970 Apply_Compile_Time_Constraint_Error in the component case. Also
2971 call that when Array_Comp is True, with an appropriate warning for
2972 the array component case. Only create an explicit initialization
2973 by null in the case of an object of a null-excluding access type
2974 (and no longer do that in the component case).
2975 * sem_ch3.adb (Check_Component): Add a Boolean parameter
2976 Array_Comp defaulted to False. Pass Empty for the Comp
2977 actual when calling Null_Exclusion_Static_Checks in the case
2978 where Comp_Decl matches Object_Decl, because we don't have a
2979 component in that case. In the case of an object or component
2980 of an array type, pass True for Array_Comp on the recursive call

2985 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
2986 compute the linux priority from the Ada priority. Call this everywhere
2987 required. In particular, the previous version was not doing this
2988 computation when setting the ceiling priority in various places. It
2989 was just converting to C.int, which results in a ceiling that is off
2992 2017-05-02 Ed Schonberg <schonberg@adacore.com>

3011 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3012 here from exp_ch9, to recognize objects whose creation requires
3013 dynamic allocation, so that the proper warning can be emitted
3014 when restriction No_Implicit_Heap_Allocation is in effect.
3015 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
3016 to emit proper warning when an object that requires dynamic

3076 2017-05-02 Yannick Moy <moy@adacore.com>
3078 * exp_ch4.adb (Expand_N_Op_Ne): Do not bump parenthese level and
3079 optimize length comparison in GNATprove mode.

3081 operator /= into negation of operator = when needed.
3082 (Expand_SPARK): Call new
3083 function to expand operator /=.
3085 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3087 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3088 Simplify the expression for a fixed-fixed division to remove
3089 divisions by constants whenever possible, as an optimization
3090 for restricted targets.

3094 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3096 2017-05-02 Bob Duff <duff@adacore.com>
3098 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3099 to find primitive ops, instead of using an Identifier that will
3100 later be looked up. This is necessary because these ops are not
3101 necessarily visible at all places where we need to call them.
3102 * exp_util.ads: Minor comment fix.
3104 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3106 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3107 references are fully conformant if they are both expansions
3108 of the discriminant of a protected type, within one of the
3109 protected operations. One occurrence may be expanded into a
3110 constant declaration while the other is an input parameter to
3111 the corresponding generated subprogram.

3115 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3116 recursivly searching composite-types for null-excluding access
3117 types and verifying them.
3118 (Analyze_Object_Declaration): Add a
3119 call to Check_Null_Excluding_Components for static verification
3120 of non-initialized objects.
3121 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3122 a parameter for a composite-type's component and an extra case
3123 for printing component information.
3125 2017-05-02 Yannick Moy <moy@adacore.com>
3127 * sem_ch10.adb (Analyze_Subunit): Take

3141 array components specially.
3143 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3145 * sem_ch8.adb (Premature_Usage): If the premature usage of
3146 an entity is as the expression in its own object decaration,
3147 rewrite the reference as Any_Id to prevent cascaded errors or
3148 compiler loops when such an entity is used in an address clause.
3150 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3152 * gcc-interface/decl.c (components_to_record): Add missing guard.

3157 Put back pending fields onto the regular list if the misalignment
3158 happens to cancel itself.
3160 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3162 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3163 controlling actual in a prefixed call, preserve the original node
3164 information if the prefix itself has been rewritten, for ASIS use.
3166 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3168 * exp_ch6.adb (Insert_Post_Call_Actions):
3169 Code clean up. Insert the post-call actions after an enclosing
3170 procedure call when N denotes a function call and appears as an
3171 actual parameter in the procedure call.
3173 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3175 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3176 for the component, also reject the attribute if the component
3177 doesn't end on a byte boundary and its scalar storage order is
3178 different from that of the enclosing record type.
3180 2017-04-28 Javier Miranda <miranda@adacore.com>
3182 * atree.ads (Info_Messages): Removed.
3183 (Warning_Info_Messages): New counter.

3212 2017-04-28 Bob Duff <duff@adacore.com>
3214 * sem_util.ads, sem_util.adb (Might_Raise): New function
3215 that replaces Is_Exception_Safe, but has the opposite
3216 sense. Is_Exception_Safe was missing various cases -- calls inside
3217 a pragma Debug, calls inside an 'if' or assignment statement,
3218 etc. Might_Raise now walks the entire subtree looking for things
3220 * exp_ch9.adb (Is_Exception_Safe): Remove.
3221 (Build_Protected_Subprogram_Body): Replace call to
3222 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3223 constants where possible).
3224 * exp_ch7.adb: Rename Is_Protected_Body -->
3225 Is_Protected_Subp_Body. A protected_body is something different
3228 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

3254 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3255 Interrupt_Handler and Attach_Handler): Generate reference
3256 to protected operation to prevent spurious warnings about
3257 unreferenced entities. Previous scheme failed with style checks
3260 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3262 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3263 that follows an expression function must not be relocated to
3264 the generated body, because it applies to the code that follows.
3266 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3268 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3269 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3270 code that might violate the more stringent checking for 'Access
3271 introduced in Ada 2005.
3273 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3275 * a-cforse.adb: minor style fix in comment.
3277 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3279 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3280 initialize Block_Decls variable.
3281 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3282 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

3291 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3293 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3295 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3296 node between access types, freeze the designated type as well,
3297 so that dispatch table pointers are created in the proper scope,
3298 and not in the constructed body of the expression function.
3300 2017-04-28 Bob Duff <duff@adacore.com>
3302 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3303 value makes large compilations faster, but small compilations slower.
3305 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3307 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3309 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3311 * erroutc.adb (Compilation_Errors): Do not consider info messages
3312 as suitable warnings when warnings must be treated as errors.
3313 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3314 internally-generated packages when outputting completion
3316 * errout.adb (Output_Messages): Do not consider info messages as

3319 suitable warnings when warnings must be treated as errors.
3321 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3323 * warnsw.ads: Minor fix for incorrect wording in comment.
3325 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3327 * sem_res.adb (In_Instance_Code): New predicate in
3328 Valid_Conversion, to determine whether a type conversion appears
3329 as (or within) an actual for a formal object. Type conversions
3330 in instances are not rechecked in Valid_Conversion because
3331 visibility changes between generic location andi instance may
3332 lead to spurious errors, but conversions within an actual must be
3333 fully checked, and they are not fully resolved when pre-analyzing
3336 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3338 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3339 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3340 of the relocated node will have mangled Parent pointers.
3341 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3342 tables used in conjunction with entity and itype replication.
3343 (Visit_Entity): Rewrite the restriction on which entities

3378 (Restore_Warnings): Likewise.
3379 (Save_Warnings): Likewise.
3380 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3381 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3382 components_to_record.
3383 (gnu_field_to_gnat): New function.
3384 (warn_on_field_placement): Likewise.
3385 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3386 parameters. Rename local variables and adjust recursive call.
3387 Rework final scan of the field list and implement warnings on the
3388 problematic placement of specific sorts of fields.
3390 2017-04-27 Bob Duff <duff@adacore.com>
3392 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

3397 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3398 For efficiency, cache results of Is_Internal_File_Name and
3399 Is_Predefined_File_Name in the Units table. This avoids a lot
3400 of repeated text processing.
3402 2017-04-27 Emmanuel Briot <briot@adacore.com>
3404 * g-comlin.adb (Sort_Sections): remove useless test.
3406 2017-04-27 Claire Dross <dross@adacore.com>
3408 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3409 allow the use of regular equality over elements in contracts.
3410 (Formal_Model): Ghost package containing model functions that are
3411 used in subprogram contracts.
3412 (Current_To_Last): Removed, model functions should be used instead.
3413 (First_To_Previous): Removed, model functions should be used instead.
3414 (Strict_Equal): Removed, model functions should be used instead.
3415 (No_Overlap): Removed, model functions should be used instead.
3416 (Equivalent_Keys): Functions over cursors are removed. They were
3417 awkward with explicit container parameters.
3418 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3419 allow the use of regular equality over elements in contracts.
3420 (Formal_Model): Ghost package containing model functions that

3429 * gnat1drv.adb: Code cleanup.
3431 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3433 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3434 attribute reference in a post- condition is the subprogram to
3435 which the condition applies. If the condition is inherited
3436 by a type extension, the prefix becomes a reference to the
3437 inherited operation, but there is no need to create a wrapper
3438 for this operation, because 'Result is expanded independently
3439 when elaborating the postconditions.
3441 2017-04-27 Bob Duff <duff@adacore.com>
3443 * sinput.adb: Minor code cleanup.

3445 Append(String) and Append(Name_Id) by using slice assignment
3447 * sem_util.adb (In_Instance): Speed this up by removing
3448 unnecessary tests; Is_Generic_Instance is defined for all
3450 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3451 Remove unused function.
3452 * alloc.ads (Nodes_Initial): Use a much larger value, because
3453 the compiler was spending a lot of time copying the nodes table
3454 when it grows. This number was chosen in 1996, so is rather out
3455 of date with current memory sizes. Anyway, it's virtual memory.
3456 Get rid of Orig_Nodes_...; use Node_... instead.
3457 * atree.adb (Lock): Do not release the Nodes tables; it's a
3459 Orig_Nodes_ ==> Nodes_
3460 * nlists.adb: Orig_Nodes_ ==> Nodes_
3461 * g-table.adb: Remove unused "with" clause.
3462 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3463 not be used by clients.
3464 * g-dyntab.adb (Last_Allocated): New function
3465 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3467 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3469 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3471 (Subtypes_Statically_Match): Remove duplicate check.

3491 processing for Ada 83 and instances.
3492 (Object_Access_Level): Merge the processing for indexed components
3493 and selected components.
3494 * uname.adb (Add_Node_Name): Merge the processing for stubs.

3505 of Expand_Dispatching_Call. If the denoted subprogram has a
3506 class-wide precondition, this is the only precondition that
3507 applies to the call, rather that the class-wide preconditions
3508 that may apply to the body that is executed. (This is specified
3511 2017-04-27 Yannick Moy <moy@adacore.com>
3513 * gnat1drv.adb (Adjust_Global_Switches): Issue
3514 a warning in GNATprove mode if the runtime library does not
3515 support IEEE-754 floats.

3519 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
3520 is itself inherited it does not carry any contract information,
3521 so examine its parent operation which is its Alias.
3523 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3525 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3526 prefix can be an object reference in which case Obj'Image (X)
3527 can only be interpreted as an indexing of the parameterless
3528 version of the attribute.
3529 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3530 an indexing or a slice operation if the attribute does not require
3531 parameters. In Ada2012 'Image also belongs in this category,
3532 and A'Image (lo .. hi) is legal and must be parsed as a slice.
3534 2017-04-27 Yannick Moy <moy@adacore.com>
3536 * exp_ch4.adb: Minor reformatting.
3537 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
3538 disable the CodePeer and C generation modes. Similar to the
3539 opposite actions done in CodePeer mode.

4067 and a-except-2005.adb.
4068 * raise-gcc.c: Allow build in compiler, compiled as a C++
4070 (__gnat_Unwind_ForcedUnwind): Adjust prototype.
4071 (db): Constify msg_format.
4072 (get_call_site_action_for): Don't use void arithmetic.
4073 * system.ads (Frontend_Exceptions): Set to False.
4074 (ZCX_By_Default): Set to True.
4075 (GCC_ZC_Support): Set to True.
4076 * gcc-interface/Makefile.in: No more variants for a-exexpr.adb and
4078 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
4079 in gnat1 and gnatbind.
4080 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4081 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4089 modifications in functional containers.
4090 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4091 to improve readablity. Subprograms are separated between basic
4092 operations, constructors and properties. Universally quantified
4093 formulas in contracts are factorized in independant functions
4094 with a name and a comment. Names of parameters are improved.
4096 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4098 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4100 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4102 * sem_res.adb (Resolve_Type_Conversion): Do not
4103 install a predicate check here since this is already done during
4104 the expansion phase. Verify whether the operand satisfies the
4105 static predicate (if any) of the target type.
4106 * sem_ch3.adb (Analyze_Object_Declaration): Do
4107 not install a predicate check if the object is initialized by
4108 means of a type conversion because the conversion is subjected
4111 2017-04-27 Tristan Gingold <gingold@adacore.com>
4113 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
4114 replaced by their variants).
4116 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

4120 a-cofuma.ads, a-cofuba.adb, a-cofuba.ads: Minor reformatting.
4122 2017-04-27 Tristan Gingold <gingold@adacore.com>
4124 * s-excmac-gcc.ads, s-excmac-gcc.adb,
4125 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
4128 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4130 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4131 the loop which detects potential enclosing transient scopes. The
4132 loop now terminates much earlier as transient scopes are bounded
4133 by packages and subprograms.
4135 2017-04-27 Claire Dross <dross@adacore.com>
4137 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4138 allow the use of regular equality over elements in contracts.
4139 (Cursor): Type is now public so that it can be used in
4141 (Formal_Model): Ghost package containing
4142 model functions that are used in subprogram contracts.
4143 (Current_To_Last): Removed, model functions should be used
4145 (First_To_Previous): Removed, model functions should
4147 (Strict_Equal): Removed, model functions
4148 should be used instead.
4149 (Append): Default parameter value
4150 replaced by new wrapper to allow more precise contracts.
4151 (Insert): Default parameter value replaced by new wrapper to
4152 allow more precise contracts.
4153 (Delete): Default parameter
4154 value replaced by new wrapper to allow more precise contracts.
4155 (Prepend): Default parameter value replaced by new wrapper to
4156 allow more precise contracts.
4157 (Delete_First): Default parameter
4158 value replaced by new wrapper to allow more precise contracts.
4159 (Delete_Last): Default parameter value replaced by new wrapper

4164 * exp_spark.adb (Expand_SPARK): Perform specialized expansion
4165 for object declarations.

4168 Default_Initial_Condition procedure of a type under the SPARK
4169 elaboration checks umbrella.
4171 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4173 * sem.adb (Analyze): Diagnose an illegal iterated component
4175 * sem_util.ads, sem_util.adb

4180 * adaint.c (__gnat_get_current_dir): Return 0 in length if
4182 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4183 exception if getcwd failed.

4188 entities with special prefix.
4190 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4192 * debug.adb Change the documentation of switch -gnatd.s.
4193 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4194 to manage the secondary stack when an enclosing scope already
4195 performs this functionality (aka relaxed management). Switch
4196 -gnatd.s may be used to force strict management in which case
4197 the block will manage the secondary stack unconditionally. Add
4198 a guard to stop the traversal when encountering a package or a
4201 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4203 * sem_res.adb (Resolve_Call): Refine further the handling of
4204 limited views of return types in function calls. If the function
4205 that returns a limited view appears in the current unit,
4206 we do not replace its type by the non-limited view because
4207 this transformation is performed int the back-end. However,
4208 the type of the call itself must be the non-limited view, to
4209 prevent spurious resolution errors.
4211 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4213 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4214 Removed, proposed implementation using generics for class-wide
4215 preconditions proved impractical.
4216 (Class_Wide_Clone): New attribute of subprogram. Designates
4217 subprogram created for primitive operations with class-wide
4218 pre/postconditions that contain calls to other primitives. The
4219 clone holds the body of the original primitive, but the
4220 pre/postonditions do not apply to it. The original body is
4221 rewritten as a wrapper for a call to the clone.
4222 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4223 the flag is set, no code for the corresponding pre/postconditions
4224 is inserted into its body.
4226 2017-04-27 Bob Duff <duff@adacore.com>
4228 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
4229 Scalar_Storage_Order if -gnatI is given.
4230 * sem_prag.adb (Analyze_Pragma): Ignore
4231 Default_Scalar_Storage_Order if -gnatI is given.

4242 (Remove): New function that removes an element from a sequence.
4243 (Insert): New function that adds anywhere in a sequence.

4256 of attribute 'Result is not considered a violation of pragma
4259 2017-04-27 Justin Squirek <squirek@adacore.com>
4261 * cstand.adb (Create_Standard): Correctly set
4262 Directly_Designated_Type for Any_Access.

4272 private child of Ada.Containers used to implement all functional
4274 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4275 child of Ada.Containers. It provides functional indefinite unbounded
4276 maps which can be used as high level models for specification
4278 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4279 child of Ada.Containers. It provides functional indefinite unbounded
4280 sets which can be used as high level models for specification
4282 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4283 child of Ada.Containers. It provides functional indefinite unbounded
4284 vectors which can be used as high level models for specification
4286 * Makefile.rtl: Add new packages.
4287 * impunit.adb: Add new packages.
4289 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4291 * sem_ch4.adb: Minor reformatting.
4293 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4295 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4296 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4297 point type actual that has user-defined arithmetic primitives,
4298 when there is a previous actual for a formal package that defines
4299 a fixed-point type with the parent user-defined operator.
4301 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4303 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4304 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4305 the component type allows range checks.
4307 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4309 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4310 corresponding declaration, because formal derived types are
4311 rewritten as private extensions.
4313 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4315 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4316 dimensions of operands if node has been analyzed already, because
4317 previous analysis and dimension checking will have removed the
4318 dimension information from the operands.
4320 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4322 * debug.adb: Document the use of switch -gnatd.s.
4323 * einfo.ads Update the documentation on attribute
4324 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4325 the uses of these attributes from certain entities.

4327 which determines whether the block should continue to manage
4328 the secondary stack.

4382 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4383 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4384 Ada_2012 instead of Ada_2005 to be compatible with the above
4386 * bindgen.adb: Silence new warning on pragma Ada_95.
4388 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

4400 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4401 Fix spelling mistakes.
4403 2017-04-25 Bob Duff <duff@adacore.com>
4405 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4406 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4407 for source buffers. Fix misc obscure bugs.
4408 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4409 checking, for source buffers. Modify representation clause for
4410 Source_File_Record as appropriate. Move Source_File_Index_Table
4411 from spec to body, because it is not used outside the body.
4412 Move Set_Source_File_Index_Table into the private part, because
4413 it is used only in the body and in children. Use trickery to
4414 modify the dope in the generic instantiation case. It's ugly,
4415 but not as ugly as the previous method. Fix documentation.
4416 Remove obsolete code.

4432 expander is not active or when index/range checks are suppressed
4434 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4435 Remove variants that include a Supress parameter. These routines
4436 are never used, and were introduced before the current scope-based
4437 check suppression method.
4439 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

4467 error on the return type of an expression function that is a
4468 completion, if the type is derived from a generic formal type.
4470 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4488 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4489 the Internal_Source buffer. This removes the incorrect call to "="
4490 the customer noticed.
4491 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4492 eventually need to eliminate them altogether. Or else get rid
4493 of zero-origin addressing.

4870 operand as universal real when the operand is a multiplication
4871 or a division where both operands are of any fixed type.

5000 until after the processing of invariants for the full view.
5001 (Build_Invariant_Procedure_Declaration): Remove condition
5002 to return if an interface type is encountered and add
5003 condition to convert the formal parameter to its class-wide
5004 counterpart if Work_Typ is abstract.

5026 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5027 (10-15): if derived type T with progenitors is abstract,
5028 and primitive P of this type inherits non-trivial classwide
5029 preconditions from both a parent operation and from an interface
5030 operation, then the inherited operation is abstract if the parent
5031 operation is not null.
5032 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5033 with Covered_Interface_Op to yield the actual interface operation
5034 that is implemented by a given inherited operation.

5061 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5062 dereference is introduced for the object, and the object is
5063 overloaded, do not check whether it is aliased, because it may

5066 attribute types with the same designated type keep either of
5067 them and do not report an ambiguity. A true ambiguity will be

5072 * a-numeri.ads: Change the encoding of Greek letter Pi from
5073 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5074 to indicate the encoding. We considered using a byte order mark
5075 (BOM), but that causes various trouble (misc software eats the
5076 BOM, if you have a patch with a BOM, then it's not at the start
5077 of the patch, so it's not a BOM, the BOM affects with-ing files,

5121 enforce legality rule on classwide preconditions inherited from
5122 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5123 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5124 subprogram need not be dispatching if it appears in a precondition
5125 for an abstract or null subprogram.
5127 2017-04-25 Gary Dismukes <dismukes@adacore.com>

5139 (Is_Predefined_File_Name): Likewise. Adjust comment.
5141 2017-04-25 Bob Duff <duff@adacore.com>
5143 * exp_aggr.adb (Component_Count): Protect the
5144 arithmetic from attempting to convert a value >= 2**31 to Int,
5145 which would otherwise raise Constraint_Error.
5147 2017-04-25 Bob Duff <duff@adacore.com>
5149 * opt.ads (Locking_Policy): Fix incorrect documentation. The

5173 Save and restore the value of global flag
5174 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

5176 the corresponding spec or the body must ignore all SPARK_Mode
5177 pragmas found within.
5178 (Analyze_Subprogram_Declaration): Mark
5179 the spec when it needs to ignore all SPARK_Mode pragmas found
5180 within to allow the body to infer this property in case it is
5181 instantiated or inlined later.
5182 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5183 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5184 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5185 when the corresponding spec also ignored all SPARK_Mode pragmas
5187 (Analyze_Package_Declaration): Mark the spec when

5241 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5243 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5244 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5245 variable and set it to True whenever the main hash table is
5246 populated. Short- circuit the Assoc function if it is false
5247 and add associated guards.
5249 2017-04-25 Olivier Hainque <hainque@adacore.com>
5251 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5252 specs without elaboration code that have an elaboration counter
5253 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5254 * sem_ch10.adb (Analyze_Compilation_Unit):
5255 Set_Elaboration_Entity_Required when requested to preserve
5256 control flow, to ensure the unit elaboration is materialized at
5257 bind time, resulting in the inclusion of the unit object file
5258 in the executable closure at link time.
5260 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5262 * exp_dbug.adb: In Debug_Renaming_Declaration,
5263 when dealing with indexed component, accept to produce a renaming
5264 symbol when the index is an IN parameter or when it is a name
5265 defined in an outer scope.
5267 2017-04-25 Yannick Moy <moy@adacore.com>
5269 * errout.adb (Error_Msg): Adapt continuation
5270 message in instantiations and inlined bodies for info messages.
5272 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5274 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5275 Use direct 4-character slice comparisons.
5277 pragma Inline. (Has_Suffix): Delete.
5278 (Is_Internal_File_Name):
5279 Test Is_Predefined_File_Name first.
5280 (Is_Predefined_File_Name):

5284 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5286 * checks.adb (Insert_Valid_Check): Code cleanup.
5287 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5288 (Expand_Actuals): Generate proper copy-back for a validation
5289 variable when it acts as the argument of a type conversion.
5290 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5291 predicate to operate on type qualifications.
5293 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5295 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5298 2017-04-25 Bob Duff <duff@adacore.com>
5300 * sem_prag.adb (No_Return): Give an error if the pragma applies
5301 to a body. Specialize the error for the specless body case,
5302 as is done for (e.g.) pragma Convention.
5303 * debug.adb: Add switch -gnatd.J to disable the above legality
5304 checks. This is mainly for use in our test suite, to avoid
5305 rewriting a lot of illegal (but working) code. It might also
5306 be useful to customers. Under this switch, if a pragma No_Return
5307 applies to a body, and the procedure raises an exception (as it
5308 should), the pragma has no effect. If the procedure does return,
5309 execution is erroneous.
5311 2017-04-25 Bob Duff <duff@adacore.com>
5313 * exp_ch6.adb (Expand_Actuals): This is the
5314 root of the problem. It took N as an 'in out' parameter, and in
5315 some cases, rewrote N, but then set N to Original_Node(N). So
5316 the node returned in N had no Parent. The caller continued
5317 processing of this orphaned node. In some cases that caused a
5318 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5319 and trips over the Empty Parent). The solution is to make N an
5320 'in' parameter. Instead of rewriting it, return the list of
5321 post-call actions, so the caller can do the rewriting later,
5322 after N has been fully processed.
5323 (Expand_Call_Helper): Move most of Expand_Call here. It has
5324 too many premature 'return' statements, and we want to do the
5325 rewriting on return.
5326 (Insert_Post_Call_Actions): New procedure to insert the post-call
5327 actions in the appropriate place. In the problematic case,
5328 that involves rewriting N as an Expression_With_Actions.
5329 (Expand_Call): Call the new procedures Expand_Call_Helper and
5330 Insert_Post_Call_Actions.
5332 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5334 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5335 properly type derived from generic formal types, to handle
5336 properly modified version of ACATS 4.1B B611017.
5338 2017-04-25 Javier Miranda <miranda@adacore.com>
5340 * exp_unst.adb (Subp_Index): Adding missing
5341 support for renamings and functions that return a constrained
5342 array type (i.e. functions for which the frontend built a
5343 procedure with an extra out parameter).
5345 2017-04-25 Pascal Obry <obry@adacore.com>
5347 * s-string.adb: Minor code clean-up.
5349 2017-04-25 Bob Duff <duff@adacore.com>

5356 2017-04-25 Bob Duff <duff@adacore.com>
5358 * prep.adb (Preprocess): Remove incorrect
5359 Assert. Current character can be ASCII.CR.
5361 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5363 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5364 convention Stdcall, which has a number of exceptions. Convention
5365 is legal on a component declaration whose type is an anonymous
5366 access to subprogram.
5368 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5370 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5371 (Try_One_Prefix_Interpretation): Use the base type when dealing
5372 with a subtype created for purposes of constraining a private
5373 type with discriminants.
5375 2017-04-25 Javier Miranda <miranda@adacore.com>
5377 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

5379 dispatching primitives (Restore_Warnings): Restore warning on
5380 late dispatching primitives (Save_Warnings): Save warning on late
5381 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5382 to enable/disable this warning.
5383 (WA_Warnings): Set warning on late dispatching primitives.
5384 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5385 that its parent type has a private extension.
5386 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5388 * usage.adb: Document -gnatw.j and -gnatw.J.
5390 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5392 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5395 2017-04-25 Bob Duff <duff@adacore.com>
5397 * binde.adb (Validate): Do not pass dynamic strings
5398 to pragma Assert, because older compilers do not support that.
5400 2017-04-25 Bob Duff <duff@adacore.com>
5402 * s-fileio.adb (Close): When a temp file is
5403 closed, delete it and clean up its Temp_File_Record immediately,
5404 rather than waiting until later.
5405 (Temp_File_Record): Add File
5406 component, so Close can know which Temp_File_Record corresponds
5407 to the file being closed.
5408 (Delete): Don't delete temp files,
5409 because they are deleted by Close.
5410 (Open): Set the File component
5411 of Temp_File_Record. This requires moving the creation of the
5412 Temp_File_Record to the end, after the AFCB has been created.
5414 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5416 * checks.adb (Insert_Valid_Check): Do not generate
5417 a validity check when inside a generic.
5419 2017-04-25 Yannick Moy <moy@adacore.com>
5421 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
5423 2017-04-25 Arnaud Charlet <charlet@adacore.com>

5431 concerning inheritance of class-wide preconditions do not apply
5434 2017-04-25 Bob Duff <duff@adacore.com>
5436 * s-ficobl.ads: Minor comment fix.
5438 2017-04-25 Yannick Moy <moy@adacore.com>
5440 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5441 conversions from float to integer in GNATprove mode.
5442 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5443 to call Apply_Type_Conversion_Checks, so that range checks
5444 are properly positioned when needed on conversions, including
5445 when converting from float to integer. (Determine_Range): In
5446 GNATprove mode, take into account the possibility of conversion
5447 from float to integer.
5448 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5449 check on conversions from fixed-point to integer, not anymore
5450 on conversions from floating-point to integer, when in GNATprove
5453 2017-04-25 Yannick Moy <moy@adacore.com>
5455 * checks.adb (Determine_Range_R): Special case type conversions
5456 from integer to float in order to get bounds in that case too.
5457 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5458 mode, for computations involved in interval checking.

5470 (Validated_Object): New routine along with pragma Inline.
5471 (Set_Validated_Object): New routine along with pragma Inline.
5472 * exp_attr.adb (Make_Range_Test): Add processing for validation
5473 variables to avoid extra reads and copies of the prefix.
5474 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5475 variables in order to reflect any changes done in the variable
5476 back into the original object.
5477 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5478 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5484 generate Finalize_Address routines for CodePeer.
5486 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5488 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5489 Analyze_Pre_Post_Condition, to implement the legality checks
5490 mandated by AI12-0131: Pre'Class shall not be specified for an
5491 overriding primitive subprogram of a tagged type T unless the
5492 Pre'Class aspect is specified for the corresponding primitive
5493 subprogram of some ancestor of T.
5495 2017-04-25 Bob Duff <duff@adacore.com>
5497 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5498 is redundant, set its Used_Operations to empty. This is only
5499 necessary for use clauses that appear in the parent of a generic
5500 child unit, because those use clauses get reanalyzed when we
5501 instantiate the generic, and we don't want the Used_Operations
5502 carried over from the original context (where it was probably
5505 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5507 * exp_ch6.adb: Minor reformatting.

5516 the above bugs won't rear their ugly heads again.
5518 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5520 * sem_ch8.adb (Find_Type): For an attribute reference
5521 'Class, if prefix type is synchronized and previous errors
5522 have suppressed the creation of the corresponding record type,
5523 create a spurious class-wide for the synchonized type itself,
5524 to catch other misuses of the attribute
5526 2017-04-25 Steve Baird <baird@adacore.com>
5528 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5529 is True, then don't generate the accessibility check for the
5530 tag of a tagged result.

5532 if CodePeer_Mode is True, then don't generate the
5533 tag checks for the result of call to an instance of
5534 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5535 descendant of" check and the accessibility check).
5537 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5539 * sem_ch13.adb: Code cleanups.
5540 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

5545 * exp_ch4.adb (Library_Level_Target): New function.
5546 (Expand_Concatenate): When optimization is enabled, also expand
5547 the operation out-of-line if the concatenation is present within
5548 the expression of the declaration of a library-level object and
5549 not only if it is the expression of the declaration.
5551 2017-04-25 Bob Duff <duff@adacore.com>
5553 * freeze.adb (Freeze_Object_Declaration): Do
5554 not Remove_Side_Effects if there is a pragma Linker_Section,
5555 because in that case we want static initialization in the
5556 appropriate section.
5558 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5560 * exp_dbug.adb: Minor rewording and reformatting.
5562 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5564 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5565 handle the proposed changes to rules concerning potentially
5566 unevaluated expressions, to include selected components that
5567 do not depend on discriminants, and indexed components with
5569 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5570 predicate in quantified expression, and fix bugs in the handling
5571 of case expressions and membership test.
5572 (Analyze_Attribute_Old_Result): use new predicate.

5613 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5614 internal calls that appear in preconditions of protected
5615 operations, in default values for same, and in contract guards
5616 for contract cases in SPARK.
5618 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5620 * a-numaux.ads: Fix description of a-numaux-darwin

5627 * a-numaux-x86.ads: Fix package description.
5628 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5629 (Reduce): Adjust and complete description. Call Is_Nan instead of
5630 testing manually. Use an integer temporary to hold rounded value.
5631 * a-numaux-darwin.adb (Reduce): Likewise.
5632 (Is_Nan): New function.
5634 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5636 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5637 on analysis of prefix whose type is a current instance of a
5638 synchronized type, but where the prefix itself is an entity that

5643 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5644 the identity of callable entities therein, because they have been
5645 properly resolved, and prefixed calls may have been rewritten
5648 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5650 * exp_ch3.adb (Build_Init_Statements): Convert
5651 the expression of the pragma/aspect Secondary_Stack_Size to

5653 it to the Secondary_Stack_Size component of the task type's
5654 corresponding record.

5659 (etc) optimizations when the type is modular and the offsets
5662 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5664 * s-osinte-freebsd.ads: Minor comment tweaks
5666 2017-04-25 Javier Miranda <miranda@adacore.com>
5668 * urealp.adb (UR_Write): Reverse previous patch
5669 adding documentation on why we generate multiplications instead
5670 of divisions (needed to avoid expressions whose computation with
5671 large numbers may cause division by 0).
5673 2017-04-25 Bob Duff <duff@adacore.com>
5675 * erroutc.adb (Set_Specific_Warning_Off,
5676 Set_Warnings_Mode_Off): Use the correct source file for
5677 Stop. Was using Current_Source_File, which is only valid during
5678 parsing. Current_Source_File will have a leftover value from
5679 whatever file happened to be parsed last, because of a with_clause
5682 2017-04-25 Bob Duff <duff@adacore.com>
5684 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5685 to In_Predefined_Unit, but including GNAT units.
5686 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5687 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5688 because Should_Ignore_Pragma was not working reliably outside
5689 the parser, because Current_Source_File is not valid.
5690 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5691 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5728 Build_Invariant_Procedure_Body.
5729 (Build_Invariant_Procedure_Body):
5730 Remove refactored calls and integrated code from
5731 Add_Parent_Invariants and Add_Interface_Invariants.
5733 2017-04-25 Johannes Kanig <kanig@adacore.com>
5735 * errout.adb (Output_Messages): Adjust computation of total
5737 * erroutc.adb (Error_Msg): In statistics counts, deal
5738 correctly with informational messages that are not warnings.

5753 correction to comments, move out large conditional and scope
5754 traversal into a predicate.
5755 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5758 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5760 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5761 of prefix whose type is a current instance of a synchronized
5762 type. If the prefix is an object this is an external call (or
5763 requeue) that can only access public operations of the object. The
5764 previous predicate was too restrictive, and did not allow public
5765 protected operations, only task entries.
5767 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5769 * sem_ch5.adb, fname.adb: Minor reformatting.
5771 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5773 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5774 * einfo.ads Update the placement of
5775 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5777 (Is_Anonymous_Access_Type): New routine.
5778 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5779 master for an access type subject to pragma No_Heap_Finalization.
5780 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5781 allocated or deallocated does not finalization actions if the
5782 associated access type is subject to pragma No_Heap_Finalization.
5783 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5784 * par-prag.adb Pragma No_Heap_Finalization does not need special
5785 processing from the parser.
5786 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5787 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5788 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5789 No_Heap_Finalization.
5790 (Analyze_Pragma): Add processing for
5791 pragma No_Heap_Finalization. Update various error messages to
5792 use Duplication_Error.
5793 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5794 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5795 and corresponding pragma id.
5797 2017-04-25 Bob Duff <duff@adacore.com>
5799 * freeze.adb (Freeze_Record_Type): Use the
5800 underlying type of the component type to determine whether it's
5801 elementary. For representation clause purposes, a private type
5802 should behave the same as its full type.
5803 * fname.ads, fname.adb (Is_Predefined_File_Name):
5804 Make sure things like "system.ali" are recognized as predefined.
5806 2017-04-25 Javier Miranda <miranda@adacore.com>

5812 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5813 element iterator when the name is an overloaded function call,
5814 one of whose interpretations yields an array.
5816 2017-04-25 Bob Duff <duff@adacore.com>
5818 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5819 Is_Internal_Unit_Name): New functions for operating on unit
5820 names, as opposed to file names. There's some duplicated code
5821 with fname.adb, which is unfortunate, but it seems like we don't
5822 want to add dependencies here.
5823 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5824 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5825 is not a file name at all.
5826 * fname.ads, fname.adb: Document the fact that
5827 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5828 for ALI files, and fix the code so it works properly for ALI
5829 files. E.g. these should return True for "system.ali".
5831 2017-04-25 Justin Squirek <squirek@adacore.com>
5833 * exp_util.adb (Add_Invariant): Removed,
5834 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5835 and Add_Own_Invariant. (Add_Invariant_Check): Used
5836 for adding runtime checks from any kind of invariant.
5837 (Add_Inherited_Invariant): Generates invariant checks for
5838 class-wide invariants (Add_Interface_Invariants): Removed, code
5839 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

5841 Removed, code moved to Build_Invariant_Procedure_Body
5842 (Build_Invariant_Procedure_Body): Add refactored calls
5843 and integrated code from Add_Parent_Invariants and
5844 Add_Interface_Invariants.
5845 (Process_Type): Removed, the
5846 relavant code was inlined into both Add_Own_Invariant and
5847 Add_Inherited_Invariant.
5849 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5851 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5868 and Build_Invariant_Procedure_Declaration.
5869 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5870 and Build_Invariant_Procedure_Declaration from exp_ch7
5871 and break-out Is_Untagged_Private_Derivation from
5872 Build_Invariant_Procedure_Body.
5873 (Replace_Type_References):
5874 Append an extra parameter to allow for dispatching replacements
5875 and add the corrasponding logic.
5876 (Type_Invariant): Remove
5877 Replace_Typ_Refs and replace its references with calls to
5878 Replace_Type_References.
5879 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5881 2017-04-25 Bob Duff <duff@adacore.com>
5883 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5884 that returns True when appropriate.
5885 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5886 when compiling predefined files.
5887 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5888 "gnat.adc" should not be considered a predefined file name.
5889 That required (or at least encouraged) a lot of cleanup of global
5890 variable usage. We shouldn't be communicating information via
5891 the global name buffer.
5892 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5893 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5896 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5898 * osint.adb (Find_File): Handle properly a request for a
5899 configuration file whose name is a directory.

5913 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5914 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5915 Add String_To_Name with no side effects.
5917 2017-04-25 Justin Squirek <squirek@adacore.com>
5919 * sem_ch3.adb (Analyze_Declarations): Add
5920 additional condition for edge case.

5924 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5925 reserved words inside pragmas. This is necessary to allow the
5926 pragma name Interface to be used in pragma Ignore_Pragma.

5929 2017-04-25 Javier Miranda <miranda@adacore.com>
5931 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

5952 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
5953 the first pass over an assignment statement with target names,
5954 to prevent the generation of subtypes (such as discriminated
5955 record components)that may carry the target name outside of the

5957 the assignment is reanalyzed in full.
5958 (Analyze_Target_Name): Handle properly class-wide types.

5990 properties of the private type to the full view in case the full
5991 view derives from a parent type and inherits a DIC pragma.
5992 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
5993 DIC pragma is placed at the top of a declarative region.
5995 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
5997 * a-tasatt.adb: Complete previous change and use an unsigned
5998 int to avoid overflow checks.
6000 2017-04-25 Ed Schonberg <schonberg@adacore.com>

6003 the error message when the attribute reference is an actual in
6004 a call to a subprogram inherited from a generic formal type with
6005 unknown discriminants, which makes the subprogram and its formal
6006 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6008 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6010 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6015 * sem_attr.adb (Type_Key): Add code in the
6016 recursive Compute_Type_Key to protect against fetching the source
6017 code for Standard, in case a component of the type is declared
6018 in Standard. There was already code to do this for the original
6019 type, but not for its components.
6021 2017-04-25 Javier Miranda <miranda@adacore.com>
6023 * exp_ch3.adb (Build_Initialization_Call): Handle
6024 subtypes of private types when searching for the underlying full
6025 view of a private type.

6040 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
6041 context is a package declaration.
6042 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
6043 Analyze_Generic_Package_Declaration): ditto.

6064 * s-memory.adb: Add a comment regarding efficiency.
6065 * atree.adb: Fix the assertion, and combine 2 assertions into one,

6717 (Check_Dependency_Clause): Properly detect a match between two
6718 'Result attributes. Update the various post-match cases to use

6722 (Remove_Extra_Clauses): New routine.
6723 (Report_Extra_Clauses): Remove the detection of ... => null

6728 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
6729 report on spurious overlaps between values involving a subtype
6730 with a static predicate, because the expansion of such a subtype

6782 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6783 an object declaration for an array type with a modular index type
6784 with the size of Long_Long_Integer. Special processing is needed
6785 in this case to compute reliably the size of the object, and
6786 eventually to raise Storage_Error, when wrap-around arithmetic
6787 might compute a meangingless size for the object.
6789 2017-01-23 Justin Squirek <squirek@adacore.com>

6796 * sem_res.adb (Resolve_Call): In the part of the code where
6797 it is deciding whether to turn the call into an indexed
6798 component, avoid doing so if the call is to an instance of
6799 Unchecked_Conversion. Otherwise, the compiler turns it into an
6800 indexed component, and resolution of that turns it back into a
6801 function call, and so on, resulting in infinite recursion.
6802 * sem_util.adb (Needs_One_Actual): If the first formal has a
6803 default, then return False.

6850 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6851 must be treated as delayed aspect even if the expression is
6852 a literal, because the aspect affects the freezing and the

6905 returns a limited view of a type and at the point of the call the
6906 function is not declared in the extended main unit then replace
6907 it with the non-limited view, which must be available. If the
6908 called function is in the extended main unit then no action is
6909 needed since the back-end handles this case.

6923 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6924 base type differs from that of the completion and the private
6925 subtype is an itype (created for a constraint on an access

7113 statements within an element iterator loop are only analyzed
7114 agter the loop is rewritten. Within a generic the analysis must
7115 be performed in any case to complete name capture.
7117 2017-01-19 Bob Duff <duff@adacore.com>
7119 * sem_prag.adb (Analyze_Pragma): Check for ignored pragmas first,

7125 * exp_ch7.adb (Build_Invariant_Procedure_Body): Semi-insert the
7126 body into the tree for GNATprove by setting its Parent field. The

7130 declaration into the tree for GNATprove by setting its Parent
7132 * freeze.adb (Freeze_Arry_Type):In GNATprove mode, do not add

7134 so that the procedure can be used to check the array type
7136 (Freeze_Record_Type): In GNATprove mode, do
7137 not add the component invariants to the record type invariant
7138 procedure so that the procedure can be used to check the record
7139 type invariants if any.

7159 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7161 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
7162 type, ie. a type whose component is a character type, and the
7163 aggregate is positional, do not convert into a string literal
7164 if the index type is not an integer type, because the original
7165 type may be required in an enclosing operation.
7167 2017-01-19 Bob Duff <duff@adacore.com>
7169 * binde.adb, debug.adb: Enable new elaboration order algorithm
7170 by default. -dp switch reverts to the old algorithm.

7215 * exp_ch6.adb (Expand_Call): Remove side effects on
7216 actuals that are allocators with qualified expression since the
7217 initialization of the object is performed by means of individual
7218 statements (and hence it must be done before the call).
7220 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7222 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7223 (Build_Derived_Enumeration_Type): If the derived type inherits a
7224 dynamic predicate from its parent, the bounds of the type must
7225 freeze because an explicit constraint is constructed for the
7226 type and the corresponding range is elaborated now.
7228 2017-01-19 Arnaud Charlet <charlet@adacore.com>
7230 * sem_attr.ads: minor fix of inconsistent casing in comment

7256 public, for use elsewhere.
7257 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
7258 an Inlined_body, recognize a call that uses object notation

7262 2017-01-19 Bob Duff <duff@adacore.com>
7264 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
7265 in case of generic formal discrete types, because it causes crashes in

7273 2017-01-19 Bob Duff <duff@adacore.com>
7275 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
7276 Increment Warnings_Detected. It was decrementing, which is
7277 wrong since we just issued a warning message.
7278 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
7279 these variables to be of subtype Nat instead of Int, because
7280 they should never be negative.
7282 2017-01-19 Javier Miranda <miranda@adacore.com>
7284 * contracts.adb (Build_Postconditions_Procedure): Replace
7285 Generate_C_Code by Modify_Tree_For_C.

7307 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
7309 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
7311 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7313 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7314 selected component has a prefix that might be interpreted
7315 as a parameterless function call, but none of the candidate
7316 interpretations is parameterless, and there is a hidden homonym
7317 of the prefix that is a package.
7318 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7319 interpreted as a parameterless function call and its analysis
7320 fails, do not call Analyze_Selected_Component.
7322 2017-01-19 Steve Baird <baird@adacore.com>
7324 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7326 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7327 calls to a newly-defined Scalar_Range_Of_Right_View function.
7329 2017-01-19 Arnaud Charlet <charlet@adacore.com>

7334 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7335 from repeated code of Traverse_Compilation_Unit.
7336 (Traverse_Declaration_Or_Statement): fixed detection of
7337 generic subprograms and packages; also, iteration over case
7338 statement alternatives rewritten to avoid testing if the first
7339 alternative is present (since it must be present due to Ada
7340 syntax restrictions).
7342 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7344 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
7345 returning by reference not just for subprogram body stubs,

7355 identifier nodes that do not come from source, to handle properly
7356 dimensionality check within an inlined body which inclddes both
7357 original operands and rewritten operands. This removes spurious
7358 dimensionality errors in the presence of front-end inlining,
7359 as well as in SPARK mode.
7361 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7400 * scil_ll.adb: Minor style fix in comment.
7401 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
7402 even if entity is already set, because the node may be renalyzed
7403 after inlining transformations.

7432 * sem_ch6.adb (Cloned_Expression): New subprogram.
7433 (Freeze_Expr_Types): Complete previous patch since the expression
7434 of an expression-function may have iterators and loops with
7435 defining identifiers which, as part of the preanalysis of the
7436 expression, may be left decorated with itypes that will not be
7437 available in the tree passed to the backend.
7439 2017-01-13 Ed Schonberg <schonberg@adacore.com>

7477 2017-01-13 Bob Duff <duff@adacore.com>
7479 * binde.adb (Elab_New): New elaboration order algorithm
7480 that is expected to cause fewer ABE issues. This is a work in
7481 progress. The new algorithm is currently disabled, and can be
7482 enable by the -dp switch, or by modifying the Do_Old and Do_New
7483 etc. flags and rebuilding. Experimental code is included to
7484 compare the results of the old and new algorithms.
7485 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7486 can have multiple of these tables, so the old and new algorithms
7488 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7489 parameter of type array. This avoids the global variable, and
7490 allows bounds checking (which is normally defeated by the tables
7491 packages). It also ensures that the Elab_Order is read-only
7493 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7494 subprograms that need it, as above.
7495 * debug.adb: Document new -dp switch. Modify doc of old -do
7497 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7498 and Bindgen. Move writing of closure (-R and -Ra switches)

7501 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7503 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7504 function is a completion, all entities referenced in the
7505 expression are frozen. As a consequence, a reference to an
7506 uncompleted private type from an enclosing scope is illegal.
7508 2017-01-13 Javier Miranda <miranda@adacore.com>
7510 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7511 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7512 expression function declaration that is a completion, its
7513 expression causes freezing (AI12-0103).
7515 2017-01-13 Vadim Godunko <godunko@adacore.com>
7517 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7571 Iterated_Component_Associations.
7572 (Gen_Loop): Generate proper loop for an
7573 Iterated_Component_Association: loop variable has the identifier
7574 of the original association. Generate a loop even for a single
7575 component choice, in order to make loop parameter visible in
7577 (Flatten): An Iterated_Component_Association is not static.

7598 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7600 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7601 mode a choice that is a subtype with a static predicate is
7602 replaced by the values it covers. This transformation must not
7603 be performed in ASIS mode, to preserve the source for analysis.
7605 2017-01-13 Justin Squirek <squirek@adacore.com>

7620 and resolve the discrete choices and the expression of the
7622 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7623 Loop_Actions and Box_Present are attributes of
7624 N_Iterated_Component_Association nodes. Box_Present is always
7626 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7627 has a Discrete_Choices list, as specified in the RM. A
7628 Component_Association for aggregate uses instead a Choices list.
7629 We have to live with this small inconsistency because the new

7665 when not applicable due to actual requiring type conversion
7666 with possible check but no temporary value can be copied for
7667 GNATprove to see the check.
