285 2017-09-08 Yannick Moy <moy@adacore.com>
287 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
288 return the entity associated with the call.
289 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
290 Replace the internal Get_Function_Id with the new
291 Sem_Aux.Get_Called_Entity.
292 (Iterate_Call_Parameters): New
293 procedure to iterate on formals and actuals at the same time.
294 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
295 Set SPARK_Mode from spec when set, for analysis
296 of instance. Restore after analysis of instance.
297 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
298 set, for analysis of body instance. Restored automatically at
299 the end of the subprogram.
300 * gnat1drv.adb (Adjust_Global_Switches): Set
301 Check_Validity_Of_Parameters to False in GNATprove mode.
302 * opt.ads (Check_Validity_Of_Parameters): Document switch to
305 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
307 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
308 (New_Copy_Tree): ...there. Reset the hash tables only if they
309 were used in the previous invocation.
310 * s-htable.adb: Fix typo.
312 2017-09-08 Bob Duff <duff@adacore.com>
314 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
316 2017-09-08 Arnaud Charlet <charlet@adacore.com>
318 * sem_aggr.adb: minor style fix.
320 2017-09-08 Bob Duff <duff@adacore.com>
322 * sprint.adb (Write_Corresponding_Source): Ignore if there is
323 no current source file.
324 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
325 Print something helpful in case N is invalid.
326 * sprint.ads: Minor comment fix.
328 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
330 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
333 2017-09-08 Bob Duff <duff@adacore.com>
335 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
336 Ada_2020, along the same lines as the other Ada version pragmas.
338 2017-09-08 Gary Dismukes <dismukes@adacore.com>
340 * sem_ch12.adb: Minor typo fixes and reformatting.
342 2017-09-08 Yannick Moy <moy@adacore.com>
344 * sem_aggr.adb (Resolve_Record_Aggregate):
345 Rewrite bounds of aggregate subexpressions which may depend on
346 discriminants of the enclosing aggregate.
348 2017-09-08 Yannick Moy <moy@adacore.com>
350 * sem_ch5.adb: Prevent assertion failure on illegal code.
352 2017-09-08 Yannick Moy <moy@adacore.com>
354 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
355 calling Renamed_Entity on an entity which cannot be a renaming.
357 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
359 * exp_aggr.adb: Add with & use clause for Urealp.
360 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
361 elementary types instead of just discrete types.
362 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
363 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
364 Be prepared for the FP zero value in the memset case. Add small
367 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
369 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
372 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
374 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
375 of New_Copy because the latter leaves the syntactic structure of
376 the tree inconsistent (a child is accessible through two parents)
377 and prevents proper replication of itypes by subsequent calls
379 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
380 New_Copy because the latter leaves the syntactic structure of the
381 tree inconsistent (a child is accessible through two parents)
382 and prevents proper replication of itypes by subsequent calls
384 * sem_util.adb (In_Subtree): New routine.
385 (New_Copy_Tree): Reimplemented.
386 * sem_util.ads (In_Subtree): New routine.

389 2017-09-08 Ed Schonberg <schonberg@adacore.com>
391 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
392 for aspect Default_Value is a static scalar value, but it does
393 not freeze the type. Yhis allows for subsequent representation
394 clauses for the type.
396 2017-09-08 Javier Miranda <miranda@adacore.com>
398 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
399 not add entries into the undefined reference table when we are
400 compiling with errors ignored.
402 2017-09-08 Ed Schonberg <schonberg@adacore.com>
404 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
405 check if the instance is within an enclosing instance body. The
406 formal package was legal in the enclosing generic, and is
407 legal in the enclosing instantiation. This optimisation may be
408 applicable elsewhere, and it also removes spurious errors that
409 may arise with on-the-fly processing of instantiations that
410 contain Inline_Always subprograms.
412 2017-09-08 Vincent Celier <celier@adacore.com>
414 * gnatcmd.adb: Disregard empty argument of GNAT driver.
416 2017-09-08 Justin Squirek <squirek@adacore.com>
418 * checks.adb (Insert_Valid_Check): Manually decorate
419 the generated temporary for range valdity checks.
421 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
423 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
425 2017-09-08 Justin Squirek <squirek@adacore.com>
427 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
428 case to handle underscore flags.
429 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
430 new procedure to handle underscores.
432 2017-09-08 Javier Miranda <miranda@adacore.com>
434 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
435 divisions with fixed point results to avoid generating twice
436 the runtime check on divide by zero.
437 * checks.adb (Apply_Divide_Checks): Ensure that operands are
438 not evaluated twice (once for their runtime checks and once for
439 their regular computation).
441 2017-09-08 Yannick Moy <moy@adacore.com>
443 * sem_prag.adb (Analyze_Part_Of): Add missing
444 return statements after issuing errors. Add detection of
445 out-of-order item and single concurrent type.

547 * gcc-interface/Makefile.in: Enable s-trasym-dwarf.adb on x86*linux.
549 2017-09-08 Bob Duff <duff@adacore.com>
551 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
552 New routine to read the Tag robustly.
553 * exp_attr.adb (Input): Change the expansion of 'Input,
554 in the class-wide case, to call String_Input_Tag instead of
557 2017-09-08 Arnaud Charlet <charlet@adacore.com>
559 * s-rident.ads (Restriction_Id): reorder enum
560 literals, so that Pure_Barriers is no longer in range of the
561 Cunit_Boolean_Restrictions subtype.
563 2017-09-08 Nicolas Roche <roche@adacore.com>
565 * a-taster.ads, a-taster.adb: Move to libgnarl
566 * gcc-interface/Makefile.in: Remove obsolete targets. Code cleanups.

571 * exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
572 accessibility check to an interface conversion, whose purpose
573 is to perform a pointer adjustment in a dispatching call.

575 when the actual is a construct that involves a dereference of an
576 expression that includes a formal of the enclosing subprogram,
577 In such cases, the accessibility level of the actual is that of
578 the corresponding formal, which is passed in as an additional
579 actual in the outer call.
581 2017-09-08 Bob Duff <duff@adacore.com>
583 * exp_intr.adb (Add_Source_Info): Do not decode
584 file names; they were not encoded in the first place.
586 2017-09-08 Bob Duff <duff@adacore.com>
588 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
589 exceptions instead of crashes. Check for absurdly long strings
590 and empty strings. Empty strings cause trouble because they can
591 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
592 be empty, which causes an array index out of bounds.
593 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
596 2017-09-08 Arnaud Charlet <charlet@adacore.com>
598 * sem_util.adb (Is_CCT_Instance): allow use in

615 2017-09-08 Yannick Moy <moy@adacore.com>
617 * exp_attr.adb (Expand_Loop_Entry_Attribute): Do
618 not skip a loop coming from source which is rewritten into a loop.
620 2017-09-08 Ed Schonberg <schonberg@adacore.com>
622 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
623 wrapper has convention Ada, to prevent spurious warnings on
624 unconstrained array parameters.
626 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
628 * sem_prag.adb (Check_Variant): Use First_Non_Pragma/Next_Non_Pragma.

647 changes for Include_Subprogram_In_Messages.
648 * sem_ch5.adb (Check_Unreachable_Code): Supply Node parameter when
649 generating warning message.
651 2017-09-08 Ed Schonberg <schonberg@adacore.com>
653 * par-ch4.adb (P_Iterated_Component_Association): Place construct
654 under -gnat2020 flag, given that it is a future feature of
656 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
657 defining identifier as referenced to prevent spurious warnings:
658 corresponding loop is expanded into one or more loops whose
659 variable has the same name, and the expression uses those names
660 and not the original one.
662 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
664 * sem_elab.adb (Check_A_Call): Do not consider
665 references to internal variables for SPARK semantics.

684 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
686 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
687 Correction of the return type from access type to option type.
688 (Simple_HTable): Moving the Instance_Data to ads file.
690 2017-09-08 Yannick Moy <moy@adacore.com>

731 * exp_ch6.adb (Replace_Renaming_Declaration_Id): New
732 subprogram containing code that was previously inside

734 required for one of the new subprograms.
736 Invoke Make_Build_In_Place_Iface_Call_In_Anonymous_Context
737 (Expand_N_Extended_Return_Statement): Extend the
738 cases covered by an assertion on expected BIP object

741 Removing unused code; found working on this ticket.
742 (Make_Build_In_Place_Call_In_Object_Declaration): Move the code
743 that replaces the internal name of the renaming declaration
744 into the new subprogram Replace_Renaming_Declaration_Id.

752 subprogram Make_Build_In_Place_Iface_Call_In_Object_Declaration.
753 * exp_attr.adb (Expand_N_Attribute_Reference): Invoke the new
754 subprogram Make_Build_In_Place_Iface_Call_In_Anonymous_Context.

767 2017-09-08 Javier Miranda <miranda@adacore.com>
769 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
770 access to interface types. Remove also the accessibility check.
772 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
774 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
775 all the types that are referenced by the expression.
776 (Analyze_Expression_Function): Call Freeze_Expr_Types for
777 a completion instead of manually freezing the type of the
779 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
781 2017-09-08 Ed Schonberg <schonberg@adacore.com>
783 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
784 New procedure, auxiliary to Expand_Pragma_Check, to handle
785 references to the discriminants of a protected type within a
786 precondition of a protected operation. This is needed because
787 the original precondition has been analyzed in the context of
788 the protected declaration, but in the body of the operation
789 references to the discriminants have been replaved by references
790 to the discriminants of the target object, and these references
791 are only created when expanding the protected body.
793 2017-09-08 Yannick Moy <moy@adacore.com>
795 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
798 2017-09-08 Ed Schonberg <schonberg@adacore.com>
800 * exp_attr.adb (Build_Record_VS_Func): If the record is an
801 unchecked union, do not emit checks for its (non-existent)
802 discriminants, or for variant parts that depend on them.
804 2017-09-08 Justin Squirek <squirek@adacore.com>
806 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
807 Find_Comparison_Type.Try_One_Interp): Add check for generic
810 2017-09-08 Arnaud Charlet <charlet@adacore.com>

813 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
814 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
815 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
816 remaining references to AAMP_On_Target.
818 2017-09-08 Ed Schonberg <schonberg@adacore.com>

830 the underlying type to handle limited-withed types.
832 2017-09-08 Ed Schonberg <schonberg@adacore.com>
834 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
835 over a subtype of a type with a static predicate, taking into
836 account the predicate function of the parent type and the bounds
837 given in the loop specification.
838 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
839 a loop specification that is a subtype indication whose type mark
840 is a type with a static predicate, inherit predicate function,
841 used to build case statement for rewritten loop.
843 2017-09-08 Justin Squirek <squirek@adacore.com>
845 * lib-load.adb: Modify printing of error message to exclude file
848 2017-09-08 Arnaud Charlet <charlet@adacore.com>
850 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
851 don't inline subprograms declared in both visible and private
853 (In_Package_Spec): previously In_Package_Visible_Spec; now
854 detects subprograms declared both in visible and private parts
857 2017-09-08 Ed Schonberg <schonberg@adacore.com>
859 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
860 the type is an anonymous array in an object declaration, whose
861 component type has an invariant, use the object declaration
862 as the insertion point for the invariant procedure, given that
863 there is no explicit type declaration for an anonymous array type.
865 2017-09-08 Bob Duff <duff@adacore.com>
867 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

873 2017-09-08 Justin Squirek <squirek@adacore.com>
875 * lib-load.adb (Load_Main_Source): Add error output in the case a
876 source file is missing.
878 2017-09-08 Bob Duff <duff@adacore.com>
881 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
882 Default_WCEM by default (i.e. if the encoding is not specified
885 2017-09-08 Bob Duff <duff@adacore.com>
887 * s-trasym.ads (Hexa_Traceback): If
888 Suppress_Hex is True, print "..." instead of a hexadecimal

893 2017-09-08 Bob Duff <duff@adacore.com>
895 * debug.adb: Minor reformatting.
897 2017-09-08 Bob Duff <duff@adacore.com>
899 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the

904 * s-hibaen.ads: Remove obsolete file.
906 2017-09-08 Arnaud Charlet <charlet@adacore.com>

912 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
914 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
915 allow calls in the context of package spec (for pragma
916 Initializes) and bodies (for pragma Refined_State).
918 2017-09-08 Bob Duff <duff@adacore.com>
920 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
923 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
925 * debug.adb (dA): Adjust comment.
926 * gnat1drv.adb (Gnat1drv): Likewise.
927 * opt.ads (List_Representation_Info_Extended): New variable.
928 * repinfo.adb (List_Record_Info): Split implementation into...
929 (Compute_Max_Length): ...this. Recurse on records if requested.
930 (List_Record_Layout): Likewise.
931 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
932 statement, accept '0' and set List_Representation_Info_Extended
934 * usage.adb (Usage): Document new -gnatRe variant.
936 2017-09-08 Ed Schonberg <schonberg@adacore.com>
938 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
939 Do not save the given entity in the global variable Default_Pool
940 if the pragma appears within a generic unit.
942 2017-09-08 Bob Duff <duff@adacore.com>
944 * errout.adb (Delete_Warning): Do not
945 decrement Warnings_Treated_As_Errors. This is called before
946 Warnings_Treated_As_Errors has been incremented to account for
947 this warning. Decrementing it here can lead to negative values
948 of Warnings_Treated_As_Errors, raising Constraint_Error in
949 checks-on builds, and causing the compiler to return an error
950 code in checks-off builds.
952 2017-09-08 Arnaud Charlet <charlet@adacore.com>
954 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
955 entities of named concurrent types as Ref_Id and not of anonymous
956 concurrent objects (because callers already know when a conversion
957 is necessary and can easily do it); also, do not expect protected
958 types or protected objects as Context_Id (because no flow-related
959 SPARK pragmas are attached there); reflect these changes in a
960 more precise comment.
962 2017-09-08 Olivier Hainque <hainque@adacore.com>
964 * g-altive.ads: Add documentation.
966 2017-09-08 Bob Duff <duff@adacore.com>

969 * erroutc.ads: Comment fix.
971 2017-09-08 Ed Schonberg <schonberg@adacore.com>
973 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
974 for compatibility of component types of formal and actual in an
975 instantiation of a child unit, when the component type of the
976 formal is itself a formal of an enclosing generic.
978 2017-09-08 Arnaud Charlet <charlet@adacore.com>
980 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
981 sem_prag.adb to make it available for GNATprove; for concurrent
982 types replace custom scope climbing with Scope_Same_Or_Within; for
983 single concurrent objects add scope climbing (with Scope_Within),
984 which was not there (that's the primary semantic change of this
985 commit); also, when comparing a single concurrent object with
986 its corresponding concurrent type rely on equality of types,
987 not of objects (because that's simpler to code).
988 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
989 (Analyze_Global_Item): adjust special-casing of references to the
990 current instance of a concurrent unit in the Global contracts
991 of task types and single tasks objects; similar for references
992 in the protected operations and entries of protected types and
993 single protected objects (in all these cases the current instance
994 behaves as an implicit parameter and must not be mentioned in
995 the Global contract).
997 2017-09-08 Arnaud Charlet <charlet@adacore.com>
999 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1000 function calls returning a record within a subprogram call,
1003 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1005 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1006 name that designates the current instance of a child unit in its
1007 own body and appears as the prefix of a reference to an entity
1008 local to the child unit.
1009 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
1012 2017-09-08 Yannick Moy <moy@adacore.com>
1014 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
1017 2017-09-08 Tristan Gingold <gingold@adacore.com>
1019 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
1020 warnings on internal units in configurable run time mode.
1022 2017-09-08 Bob Duff <duff@adacore.com>
1024 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
1025 representation items from interfaces that the derived type
1026 implements, not just from the parent type.
1027 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
1028 this to return an empty list when there are no interfaces.
1029 * einfo.ads, sem_ch13.adb: Minor comment fixes.
1030 * sem_attr.adb: Minor comment fix.
1032 2017-09-08 Doug Rupp <rupp@adacore.com>

1039 * exp_ch4.adb (Expand_N_Allocator): Generate a
1040 call to Allocate_Any_Controlled when the allocation does not
1041 require any initialization.
1043 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1045 * sem_util.adb (Copy_Node_With_Replacement):
1046 Update the Renamed_Object field of a replicated object renaming
1049 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
1051 * exp_ch9.adb (Is_Pure_Barrier): Allow type
1052 conversions and components of objects. Simplified the detection
1053 of the Count attribute by identifying the corresponding run-time
1056 2017-09-08 Yannick Moy <moy@adacore.com>
1058 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
1059 sem_type.adb, sinfo.ads: Minor reformatting.
1061 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1063 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
1064 of Freeze_Profile, used to inhibit the freezing of the profile
1065 of an expression function declared within a nested package, when
1066 some type in the profile depends on a private type declared in

1071 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
1072 the subunit case. It's still OK to set it in the "missing subunits"

1118 the placement of a primitive operation O that renames an operation
1119 R declared in an inner package, and which is thus not a primitive

1143 previous instances. If a package IAP that is an instantiation is

1380 because the type of one of its formals has been changed.

1382 modified. Instead of receiving a pointer to an object this
1383 routine receives now a primary tag.

1419 is now consulted not only for abstract states and variables,
1420 but for all kinds of items.
1421 (Collect_Subprogram_Inputs_Outputs): Do not process formal

1557 debugging printouts comparing the two orders." Now it means
1558 "do not run Elab_New." This is of use if there are bugs that

1603 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1605 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1606 entity of a mutable type and the right-hand side is a conditional
1607 expression, resolve the alternatives of the conditional using
1608 the base type of the target entity, because the alternatives
1609 may have distinct subtypes. This is particularly relevant if
1610 the alternatives are aggregates.
1612 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1614 * checks.adb (Apply_Predicate_Check): If the expression is an
1615 aggregate that is the RHS of an assignment, apply the check to
1616 the LHS after the assignment, rather than to the aggregate. This
1617 is more efficient than creating a temporary for the aggregate,
1618 and prevents back-end crashes when the aggregate includes a
1619 dynamic "others' association.
1621 2017-09-06 Yannick Moy <moy@adacore.com>
1623 * sem_ch12.adb (Analyze_Instance_And_Renamings):

1629 * sem_res.adb (Resolve_Call): Do not issue a
1630 message for calls inside expression function, unless body was
1631 seen and is candidate for inlining.

1635 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

1637 body. do not freeze the formals of the generic unit.
1639 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1641 * errout.adb (Error_Msg): Separate the
1642 treatment for warning vs. style messages in inlinings and
1643 instantiations. Prevents blowups on calls to Warn_Insertion for
1644 style messages, which should not be called in that case because
1645 Warning_Msg_Char is not set.
1647 2017-09-06 Justin Squirek <squirek@adacore.com>
1649 * sem_prag.adb (Check_VFA_Conflicts): Created
1650 to group all Volatile_Full_Access checks relating to other
1651 representation pragmas (Mark_Component_Or_Object): Created
1652 to centeralize the flagging of attributes for the record type
1653 component case, a pragma applied individually to a component, and
1655 (Process_Atomic_Independent_Shared_Volatile):
1656 Add propagation of certain pragmas to record components and move
1657 evaluation of VFA checks

1670 2017-09-06 Bob Duff <duff@adacore.com>
1672 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1673 that is a proper body corresponding to a stub, we defer the
1674 adjustment of the sloc until after the correct adjustment has
1675 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1676 the adjustment, because it will be outside the range in (the old,
1677 incorrect) S_Adjustment.
1678 * inline.adb: Use named notation for readability and uniformity.
1679 * sinput-l.adb: Minor improvements to debugging output printed

1751 body, to prevent the current instance from being frozen before

1776 missing case of controlled generalized indexing.
1777 (Is_Source_Object): Use routine Strip to remove indirections.
1778 (Strip): New routine.
1780 2017-09-06 Bob Duff <duff@adacore.com>
1782 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1783 we include the proper header. Otherwise, we just declare the necessary
1784 things from the capabilities library. This is so we can build on
1785 machines without that library, while still enabling that library.
1786 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1787 simply return 0 if the library is not present, or not included
1790 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
1792 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

1803 has no parameter specification and no entry index, use the entry name
1804 as the end of the generated SCO statement.
1806 2017-09-06 Steve Baird <baird@adacore.com>
1808 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1809 uses of 'Image and related attributes as having side effects in
1810 order to avoid replicating such uses.
1811 * pprint.ads (Expression_Image) Add new generic formal flag
1812 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1813 (eventually) override the default.
1814 * pprint.adb (Expression_Image) If the new flag is set, then
1815 suppress the ".all" suffix when displaying a dereference whose
1816 prefix is a use of a value-capturing compiler temp of the sort
1817 generated by Expr_Util.Remove_Side_Effects .

1833 so that applies to any entity.
1835 2017-09-06 Yannick Moy <moy@adacore.com>
1837 * sem_ch3.adb (Derived_Type_Declaration): Use
1838 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1840 2017-09-06 Javier Miranda <miranda@adacore.com>
1842 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1845 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1847 * sem_dim.adb (Analyze_Dimension): In an instance, a type

1875 2017-09-06 Yannick Moy <moy@adacore.com>
1877 * freeze.adb (Check_Inherited_Conditions): Rewriting
1878 of inherited preconditions and postconditions should only occur
1879 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1880 be confused with SPARK_Mode being On.

1896 * sem_ch7.adb: Add with clause for GNAT.HTable.
1897 (Entity_Table_Size): New constant.
1898 (Entity_Hash): New function.
1899 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1900 (Is_Subprogram_Ref): Rename into...
1901 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1902 the table instead of bailing out on them. Scan the value of constants
1903 if it is not known at compile time.
1904 (Contains_Subprograms_Refs): Rename into...
1905 (Scan_Subprogram_Refs): ...this.
1906 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1907 Is_Public flag on subprograms if they are not actually referenced.
1908 (Hide_Public_Entities): Beef up comment on the algorithm.
1909 Reset the table of subprograms on entry.
1911 2017-09-06 Yannick Moy <moy@adacore.com>

1965 2017-09-06 Bob Duff <duff@adacore.com>
1967 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
1968 check back to the body, because SPARK is not yet ready for

1996 * sem_type.adb (Interface_Present_In_Ancestor): Within an
1997 expression function, or within a spec expression (default value,
1998 etc) a reference to an incomplete type is legal: legality of

2002 2017-09-06 Gary Dismukes <dismukes@adacore.com>
2004 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

2018 Move Ada.Command_Line.Response_File to System.Response_File,
2019 and make Ada.Command_Line.Response_File into a rename of
2020 System.Response_File. This is to avoid having gnatbind depend
2021 Ada.Command_Line, which would damage the bootstrap process now
2022 that Ada.Command_Line contains modern Ada (the raise expression).
2023 * gnatbind.adb: Avoid dependence on
2024 Ada.Command_Line. Depend on System.Response_File instead
2025 of Ada.Command_Line.Response_File. Change one call to
2026 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2027 to Ada.Command_Line.Argument_Count to use Arg_Count.

2038 "Assert(False)" with "return Iter", because if an iterable

2042 2017-09-06 Yannick Moy <moy@adacore.com>
2044 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

2053 (Write_Field15_Name): Update the output for
2054 Status_Flag_Or_Transient_Decl.
2055 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
2056 to loop parameters. Update the documentation of the attribute
2057 and the E_Loop_Parameter entity.
2058 * exp_ch7.adb (Process_Declarations): Remove the bogus guard
2059 which assumes that cursors can never be controlled.
2060 * exp_util.adb (Requires_Cleanup_Actions): Remove the bogus

2167 not retrievable as selected components.
2169 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2171 * sem_util.adb (Needs_One_Formal): The first formal of such a

2211 not visible in the object.
2212 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2213 side may be derived from that of the left-hand side (as in the
2214 case of an assignment with a change of representation) so the
2215 discriminant to be used in the retrieval of the value of the
2216 component must be the entity in the type of the right-hand side.

2791 * exp_ch6.adb (Expand_Call_Helper): When locating the
2792 accessibility entity created for an access parameter, handle
2793 properly a reference to a formal of an enclosing subprogram. if
2794 the reference appears in an inherited class-wide condition, it
2795 is the rewriting of the reference in the ancestor expression,
2796 but the accessibility entity must be that of the current formal.
2798 2017-05-02 Javier Miranda <miranda@adacore.com>
2800 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

2836 procedure body for a local (sub)type declaration within a
2837 predicate function. Invariant checks do not apply to these, and
2838 the expansion of the procedure will happen in the wrong scope,
2839 leading to misplaced freeze nodes.
2841 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2843 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2844 to analyze generated actions. If the main unit is a body,

2849 * einfo.adb (Declaration_Node): flip branches of

2880 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2881 Refine predicate for the case where the primitive operation
2882 is a renaming of equality. An overriding operation that is
2883 a user-defined renaming of predefined equality inherits its
2884 slot from the overridden operation. Otherwise it is treated
2885 as a predefined op and occupies the same predefined slot as
2886 equality. A call to it is transformed into a call to its alias,
2887 which is the predefined equality. A dispatching call thus uses
2888 the proper slot if operation is further inherited and called
2889 with class-wide arguments.
2891 2017-05-02 Justin Squirek <squirek@adacore.com>
2893 * errout.adb (Set_Msg_Text): Add a case to switch the message

2926 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2927 statement if the initialization call is a null procedure, as
2928 can happen with a controlled type with no explicit Initialize
2929 procedure, or an array of such.

2931 controlled components that has a trivial Initialize procedure,
2932 insert declaration for finalization counter after object

2935 finalization block and attendant declarations if component has
2936 a trivial Initialize procedure.

2970 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
2971 parameter Array_Comp to indicate the case of an array object
2972 with null-excluding components.
2973 * checks.adb (Null_Exclusion_Static_Checks):
2974 Call Compile_Time_Constraint_Error instead of
2975 Apply_Compile_Time_Constraint_Error in the component case. Also
2976 call that when Array_Comp is True, with an appropriate warning for
2977 the array component case. Only create an explicit initialization
2978 by null in the case of an object of a null-excluding access type
2979 (and no longer do that in the component case).
2980 * sem_ch3.adb (Check_Component): Add a Boolean parameter
2981 Array_Comp defaulted to False. Pass Empty for the Comp
2982 actual when calling Null_Exclusion_Static_Checks in the case
2983 where Comp_Decl matches Object_Decl, because we don't have a
2984 component in that case. In the case of an object or component
2985 of an array type, pass True for Array_Comp on the recursive call

2990 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
2991 compute the linux priority from the Ada priority. Call this everywhere
2992 required. In particular, the previous version was not doing this
2993 computation when setting the ceiling priority in various places. It
2994 was just converting to C.int, which results in a ceiling that is off
2997 2017-05-02 Ed Schonberg <schonberg@adacore.com>

3016 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3017 here from exp_ch9, to recognize objects whose creation requires

3070 a discriminant check when the associated type is a constrained
3071 subtype created for an unconstrained nominal type.
3072 * exp_attr.adb: Minor reformatting.
3074 2017-05-02 Bob Duff <duff@adacore.com>

3086 operator /= into negation of operator = when needed.
3087 (Expand_SPARK): Call new
3088 function to expand operator /=.
3090 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3092 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3093 Simplify the expression for a fixed-fixed division to remove
3094 divisions by constants whenever possible, as an optimization
3095 for restricted targets.

3099 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3101 2017-05-02 Bob Duff <duff@adacore.com>
3103 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3104 to find primitive ops, instead of using an Identifier that will
3105 later be looked up. This is necessary because these ops are not
3106 necessarily visible at all places where we need to call them.
3107 * exp_util.ads: Minor comment fix.
3109 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3111 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3112 references are fully conformant if they are both expansions
3113 of the discriminant of a protected type, within one of the
3114 protected operations. One occurrence may be expanded into a
3115 constant declaration while the other is an input parameter to
3116 the corresponding generated subprogram.

3120 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3121 recursivly searching composite-types for null-excluding access
3122 types and verifying them.
3123 (Analyze_Object_Declaration): Add a
3124 call to Check_Null_Excluding_Components for static verification
3125 of non-initialized objects.
3126 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3127 a parameter for a composite-type's component and an extra case
3128 for printing component information.

3146 array components specially.
3148 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3150 * sem_ch8.adb (Premature_Usage): If the premature usage of
3151 an entity is as the expression in its own object decaration,
3152 rewrite the reference as Any_Id to prevent cascaded errors or
3153 compiler loops when such an entity is used in an address clause.
3155 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3157 * gcc-interface/decl.c (components_to_record): Add missing guard.

3162 Put back pending fields onto the regular list if the misalignment
3163 happens to cancel itself.
3165 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3167 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3168 controlling actual in a prefixed call, preserve the original node
3169 information if the prefix itself has been rewritten, for ASIS use.
3171 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3173 * exp_ch6.adb (Insert_Post_Call_Actions):
3174 Code clean up. Insert the post-call actions after an enclosing
3175 procedure call when N denotes a function call and appears as an
3176 actual parameter in the procedure call.
3178 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3180 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3181 for the component, also reject the attribute if the component
3182 doesn't end on a byte boundary and its scalar storage order is
3183 different from that of the enclosing record type.
3185 2017-04-28 Javier Miranda <miranda@adacore.com>
3187 * atree.ads (Info_Messages): Removed.
3188 (Warning_Info_Messages): New counter.

3217 2017-04-28 Bob Duff <duff@adacore.com>
3219 * sem_util.ads, sem_util.adb (Might_Raise): New function
3220 that replaces Is_Exception_Safe, but has the opposite
3221 sense. Is_Exception_Safe was missing various cases -- calls inside
3222 a pragma Debug, calls inside an 'if' or assignment statement,
3223 etc. Might_Raise now walks the entire subtree looking for things
3225 * exp_ch9.adb (Is_Exception_Safe): Remove.
3226 (Build_Protected_Subprogram_Body): Replace call to
3227 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3228 constants where possible).
3229 * exp_ch7.adb: Rename Is_Protected_Body -->
3230 Is_Protected_Subp_Body. A protected_body is something different
3233 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

3259 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3260 Interrupt_Handler and Attach_Handler): Generate reference
3261 to protected operation to prevent spurious warnings about
3262 unreferenced entities. Previous scheme failed with style checks
3265 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3267 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3268 that follows an expression function must not be relocated to
3269 the generated body, because it applies to the code that follows.
3271 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3273 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3274 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3275 code that might violate the more stringent checking for 'Access
3276 introduced in Ada 2005.
3278 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3280 * a-cforse.adb: minor style fix in comment.
3282 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3284 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3285 initialize Block_Decls variable.
3286 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3287 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

3296 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3298 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3300 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3301 node between access types, freeze the designated type as well,
3302 so that dispatch table pointers are created in the proper scope,
3303 and not in the constructed body of the expression function.
3305 2017-04-28 Bob Duff <duff@adacore.com>
3307 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3308 value makes large compilations faster, but small compilations slower.
3310 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3312 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3314 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3316 * erroutc.adb (Compilation_Errors): Do not consider info messages
3317 as suitable warnings when warnings must be treated as errors.
3318 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3319 internally-generated packages when outputting completion
3321 * errout.adb (Output_Messages): Do not consider info messages as
3322 suitable warnings when warnings must be treated as errors.

3324 suitable warnings when warnings must be treated as errors.
3326 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3328 * warnsw.ads: Minor fix for incorrect wording in comment.
3330 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3332 * sem_res.adb (In_Instance_Code): New predicate in
3333 Valid_Conversion, to determine whether a type conversion appears
3334 as (or within) an actual for a formal object. Type conversions
3335 in instances are not rechecked in Valid_Conversion because
3336 visibility changes between generic location andi instance may
3337 lead to spurious errors, but conversions within an actual must be
3338 fully checked, and they are not fully resolved when pre-analyzing
3341 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3343 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3344 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3345 of the relocated node will have mangled Parent pointers.
3346 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3347 tables used in conjunction with entity and itype replication.
3348 (Visit_Entity): Rewrite the restriction on which entities

3383 (Restore_Warnings): Likewise.
3384 (Save_Warnings): Likewise.
3385 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3386 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3387 components_to_record.
3388 (gnu_field_to_gnat): New function.
3389 (warn_on_field_placement): Likewise.
3390 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3391 parameters. Rename local variables and adjust recursive call.
3392 Rework final scan of the field list and implement warnings on the
3393 problematic placement of specific sorts of fields.
3395 2017-04-27 Bob Duff <duff@adacore.com>
3397 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

3402 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3403 For efficiency, cache results of Is_Internal_File_Name and
3404 Is_Predefined_File_Name in the Units table. This avoids a lot
3405 of repeated text processing.
3407 2017-04-27 Emmanuel Briot <briot@adacore.com>
3409 * g-comlin.adb (Sort_Sections): remove useless test.
3411 2017-04-27 Claire Dross <dross@adacore.com>
3413 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3414 allow the use of regular equality over elements in contracts.
3415 (Formal_Model): Ghost package containing model functions that are
3416 used in subprogram contracts.
3417 (Current_To_Last): Removed, model functions should be used instead.
3418 (First_To_Previous): Removed, model functions should be used instead.
3419 (Strict_Equal): Removed, model functions should be used instead.
3420 (No_Overlap): Removed, model functions should be used instead.
3421 (Equivalent_Keys): Functions over cursors are removed. They were
3422 awkward with explicit container parameters.
3423 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3424 allow the use of regular equality over elements in contracts.
3425 (Formal_Model): Ghost package containing model functions that

3434 * gnat1drv.adb: Code cleanup.
3436 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3438 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3439 attribute reference in a post- condition is the subprogram to
3440 which the condition applies. If the condition is inherited
3441 by a type extension, the prefix becomes a reference to the
3442 inherited operation, but there is no need to create a wrapper
3443 for this operation, because 'Result is expanded independently
3444 when elaborating the postconditions.
3446 2017-04-27 Bob Duff <duff@adacore.com>
3448 * sinput.adb: Minor code cleanup.
3449 * namet.adb (Append): Create faster versions of
3450 Append(String) and Append(Name_Id) by using slice assignment
3452 * sem_util.adb (In_Instance): Speed this up by removing
3453 unnecessary tests; Is_Generic_Instance is defined for all
3455 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3456 Remove unused function.
3457 * alloc.ads (Nodes_Initial): Use a much larger value, because
3458 the compiler was spending a lot of time copying the nodes table
3459 when it grows. This number was chosen in 1996, so is rather out
3460 of date with current memory sizes. Anyway, it's virtual memory.
3461 Get rid of Orig_Nodes_...; use Node_... instead.
3462 * atree.adb (Lock): Do not release the Nodes tables; it's a
3464 Orig_Nodes_ ==> Nodes_
3465 * nlists.adb: Orig_Nodes_ ==> Nodes_
3466 * g-table.adb: Remove unused "with" clause.
3467 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3468 not be used by clients.
3469 * g-dyntab.adb (Last_Allocated): New function
3470 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3472 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3474 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3476 (Subtypes_Statically_Match): Remove duplicate check.

3493 for qualified expressions, type conversions, and unchecked
3495 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
3496 processing for Ada 83 and instances.
3497 (Object_Access_Level): Merge the processing for indexed components
3498 and selected components.
3499 * uname.adb (Add_Node_Name): Merge the processing for stubs.

3510 of Expand_Dispatching_Call. If the denoted subprogram has a
3511 class-wide precondition, this is the only precondition that
3512 applies to the call, rather that the class-wide preconditions
3513 that may apply to the body that is executed. (This is specified
3516 2017-04-27 Yannick Moy <moy@adacore.com>
3518 * gnat1drv.adb (Adjust_Global_Switches): Issue
3519 a warning in GNATprove mode if the runtime library does not
3520 support IEEE-754 floats.
3522 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3524 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
3525 is itself inherited it does not carry any contract information,
3526 so examine its parent operation which is its Alias.
3528 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3530 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3531 prefix can be an object reference in which case Obj'Image (X)
3532 can only be interpreted as an indexing of the parameterless
3533 version of the attribute.
3534 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3535 an indexing or a slice operation if the attribute does not require
3536 parameters. In Ada2012 'Image also belongs in this category,
3537 and A'Image (lo .. hi) is legal and must be parsed as a slice.
3539 2017-04-27 Yannick Moy <moy@adacore.com>
3541 * exp_ch4.adb: Minor reformatting.
3542 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
3543 disable the CodePeer and C generation modes. Similar to the
3544 opposite actions done in CodePeer mode.

4072 and a-except-2005.adb.
4073 * raise-gcc.c: Allow build in compiler, compiled as a C++
4075 (__gnat_Unwind_ForcedUnwind): Adjust prototype.
4076 (db): Constify msg_format.
4077 (get_call_site_action_for): Don't use void arithmetic.
4078 * system.ads (Frontend_Exceptions): Set to False.
4079 (ZCX_By_Default): Set to True.
4080 (GCC_ZC_Support): Set to True.
4081 * gcc-interface/Makefile.in: No more variants for a-exexpr.adb and
4083 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
4084 in gnat1 and gnatbind.
4085 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4086 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4093 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
4094 modifications in functional containers.
4095 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4096 to improve readablity. Subprograms are separated between basic
4097 operations, constructors and properties. Universally quantified
4098 formulas in contracts are factorized in independant functions
4099 with a name and a comment. Names of parameters are improved.
4101 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4103 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4105 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4107 * sem_res.adb (Resolve_Type_Conversion): Do not
4108 install a predicate check here since this is already done during
4109 the expansion phase. Verify whether the operand satisfies the
4110 static predicate (if any) of the target type.
4111 * sem_ch3.adb (Analyze_Object_Declaration): Do
4112 not install a predicate check if the object is initialized by
4113 means of a type conversion because the conversion is subjected
4116 2017-04-27 Tristan Gingold <gingold@adacore.com>
4118 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
4119 replaced by their variants).
4121 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

4125 a-cofuma.ads, a-cofuba.adb, a-cofuba.ads: Minor reformatting.
4127 2017-04-27 Tristan Gingold <gingold@adacore.com>
4129 * s-excmac-gcc.ads, s-excmac-gcc.adb,
4130 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
4133 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4135 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4136 the loop which detects potential enclosing transient scopes. The
4137 loop now terminates much earlier as transient scopes are bounded
4138 by packages and subprograms.
4140 2017-04-27 Claire Dross <dross@adacore.com>
4142 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4143 allow the use of regular equality over elements in contracts.
4144 (Cursor): Type is now public so that it can be used in
4146 (Formal_Model): Ghost package containing
4147 model functions that are used in subprogram contracts.
4148 (Current_To_Last): Removed, model functions should be used
4150 (First_To_Previous): Removed, model functions should
4152 (Strict_Equal): Removed, model functions
4153 should be used instead.
4154 (Append): Default parameter value
4155 replaced by new wrapper to allow more precise contracts.
4156 (Insert): Default parameter value replaced by new wrapper to
4157 allow more precise contracts.
4158 (Delete): Default parameter
4159 value replaced by new wrapper to allow more precise contracts.
4160 (Prepend): Default parameter value replaced by new wrapper to
4161 allow more precise contracts.
4162 (Delete_First): Default parameter
4163 value replaced by new wrapper to allow more precise contracts.
4164 (Delete_Last): Default parameter value replaced by new wrapper

4169 * exp_spark.adb (Expand_SPARK): Perform specialized expansion
4170 for object declarations.
4171 (Expand_SPARK_N_Object_Declaration): New routine.

4173 Default_Initial_Condition procedure of a type under the SPARK
4174 elaboration checks umbrella.
4176 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4178 * sem.adb (Analyze): Diagnose an illegal iterated component
4180 * sem_util.ads, sem_util.adb

4185 * adaint.c (__gnat_get_current_dir): Return 0 in length if
4187 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4188 exception if getcwd failed.

4193 entities with special prefix.
4195 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4197 * debug.adb Change the documentation of switch -gnatd.s.
4198 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4199 to manage the secondary stack when an enclosing scope already
4200 performs this functionality (aka relaxed management). Switch
4201 -gnatd.s may be used to force strict management in which case
4202 the block will manage the secondary stack unconditionally. Add
4203 a guard to stop the traversal when encountering a package or a
4206 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4208 * sem_res.adb (Resolve_Call): Refine further the handling of
4209 limited views of return types in function calls. If the function
4210 that returns a limited view appears in the current unit,
4211 we do not replace its type by the non-limited view because
4212 this transformation is performed int the back-end. However,
4213 the type of the call itself must be the non-limited view, to
4214 prevent spurious resolution errors.
4216 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4218 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4219 Removed, proposed implementation using generics for class-wide
4220 preconditions proved impractical.
4221 (Class_Wide_Clone): New attribute of subprogram. Designates
4222 subprogram created for primitive operations with class-wide
4223 pre/postconditions that contain calls to other primitives. The
4224 clone holds the body of the original primitive, but the
4225 pre/postonditions do not apply to it. The original body is
4226 rewritten as a wrapper for a call to the clone.
4227 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4228 the flag is set, no code for the corresponding pre/postconditions
4229 is inserted into its body.
4231 2017-04-27 Bob Duff <duff@adacore.com>
4233 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
4234 Scalar_Storage_Order if -gnatI is given.
4235 * sem_prag.adb (Analyze_Pragma): Ignore
4236 Default_Scalar_Storage_Order if -gnatI is given.

4245 (Remove): New function that removes an element from a set.
4246 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
4247 (Remove): New function that removes an element from a sequence.
4248 (Insert): New function that adds anywhere in a sequence.

4261 of attribute 'Result is not considered a violation of pragma
4264 2017-04-27 Justin Squirek <squirek@adacore.com>
4266 * cstand.adb (Create_Standard): Correctly set
4267 Directly_Designated_Type for Any_Access.

4277 private child of Ada.Containers used to implement all functional
4279 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4280 child of Ada.Containers. It provides functional indefinite unbounded
4281 maps which can be used as high level models for specification
4283 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4284 child of Ada.Containers. It provides functional indefinite unbounded
4285 sets which can be used as high level models for specification
4287 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4288 child of Ada.Containers. It provides functional indefinite unbounded
4289 vectors which can be used as high level models for specification
4291 * Makefile.rtl: Add new packages.
4292 * impunit.adb: Add new packages.
4294 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4296 * sem_ch4.adb: Minor reformatting.
4298 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4300 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4301 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4302 point type actual that has user-defined arithmetic primitives,
4303 when there is a previous actual for a formal package that defines
4304 a fixed-point type with the parent user-defined operator.
4306 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4308 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4309 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4310 the component type allows range checks.
4312 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4314 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4315 corresponding declaration, because formal derived types are
4316 rewritten as private extensions.
4318 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4320 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4321 dimensions of operands if node has been analyzed already, because
4322 previous analysis and dimension checking will have removed the
4323 dimension information from the operands.
4325 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4327 * debug.adb: Document the use of switch -gnatd.s.
4328 * einfo.ads Update the documentation on attribute
4329 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4330 the uses of these attributes from certain entities.

4332 which determines whether the block should continue to manage
4333 the secondary stack.

4387 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4388 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4389 Ada_2012 instead of Ada_2005 to be compatible with the above
4391 * bindgen.adb: Silence new warning on pragma Ada_95.
4393 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4395 * checks.adb (Generate_Range_Check): Revert part of previous change.

4405 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4406 Fix spelling mistakes.
4408 2017-04-25 Bob Duff <duff@adacore.com>
4410 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4411 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4412 for source buffers. Fix misc obscure bugs.
4413 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4414 checking, for source buffers. Modify representation clause for
4415 Source_File_Record as appropriate. Move Source_File_Index_Table
4416 from spec to body, because it is not used outside the body.
4417 Move Set_Source_File_Index_Table into the private part, because
4418 it is used only in the body and in children. Use trickery to
4419 modify the dope in the generic instantiation case. It's ugly,
4420 but not as ugly as the previous method. Fix documentation.
4421 Remove obsolete code.

4437 expander is not active or when index/range checks are suppressed
4439 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4440 Remove variants that include a Supress parameter. These routines
4441 are never used, and were introduced before the current scope-based
4442 check suppression method.
4444 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>
4446 * prj-part.adb, cstreams.c, osint.adb, osint.ads: Remove VMS specific

4472 error on the return type of an expression function that is a
4473 completion, if the type is derived from a generic formal type.
4475 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4493 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4494 the Internal_Source buffer. This removes the incorrect call to "="
4495 the customer noticed.
4496 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4497 eventually need to eliminate them altogether. Or else get rid
4498 of zero-origin addressing.

4782 further expansion for the unchecked union.
4783 (Expand_Attribute_Reference, case 'Write): If the type is
4784 an unchecked_union, check whether enclosing scope is a Write
4785 subprogram. Replace attribute with a Raise_Program_Error if the

4875 operand as universal real when the operand is a multiplication
4876 or a division where both operands are of any fixed type.
4877 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the

5005 until after the processing of invariants for the full view.
5006 (Build_Invariant_Procedure_Declaration): Remove condition
5007 to return if an interface type is encountered and add
5008 condition to convert the formal parameter to its class-wide
5009 counterpart if Work_Typ is abstract.

5011 (Replace_Type_Ref): Remove class-wide dispatching for the current
5012 instance of the type.

5031 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5032 (10-15): if derived type T with progenitors is abstract,
5033 and primitive P of this type inherits non-trivial classwide
5034 preconditions from both a parent operation and from an interface
5035 operation, then the inherited operation is abstract if the parent
5036 operation is not null.
5037 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5038 with Covered_Interface_Op to yield the actual interface operation
5039 that is implemented by a given inherited operation.

5066 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5067 dereference is introduced for the object, and the object is
5068 overloaded, do not check whether it is aliased, because it may

5071 attribute types with the same designated type keep either of
5072 them and do not report an ambiguity. A true ambiguity will be

5077 * a-numeri.ads: Change the encoding of Greek letter Pi from
5078 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5079 to indicate the encoding. We considered using a byte order mark
5080 (BOM), but that causes various trouble (misc software eats the
5081 BOM, if you have a patch with a BOM, then it's not at the start
5082 of the patch, so it's not a BOM, the BOM affects with-ing files,

5126 enforce legality rule on classwide preconditions inherited from
5127 both an ancestor and a progenitor (RM 6.1.1 (10-13).

5129 subprogram need not be dispatching if it appears in a precondition
5130 for an abstract or null subprogram.
5132 2017-04-25 Gary Dismukes <dismukes@adacore.com>

5146 2017-04-25 Bob Duff <duff@adacore.com>
5148 * exp_aggr.adb (Component_Count): Protect the
5149 arithmetic from attempting to convert a value >= 2**31 to Int,
5150 which would otherwise raise Constraint_Error.
5152 2017-04-25 Bob Duff <duff@adacore.com>

5181 the corresponding spec or the body must ignore all SPARK_Mode
5182 pragmas found within.
5183 (Analyze_Subprogram_Declaration): Mark
5184 the spec when it needs to ignore all SPARK_Mode pragmas found
5185 within to allow the body to infer this property in case it is
5186 instantiated or inlined later.
5187 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5188 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5189 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5190 when the corresponding spec also ignored all SPARK_Mode pragmas
5192 (Analyze_Package_Declaration): Mark the spec when

5246 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5248 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5249 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5250 variable and set it to True whenever the main hash table is
5251 populated. Short- circuit the Assoc function if it is false
5252 and add associated guards.
5254 2017-04-25 Olivier Hainque <hainque@adacore.com>
5256 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5257 specs without elaboration code that have an elaboration counter
5258 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5259 * sem_ch10.adb (Analyze_Compilation_Unit):
5260 Set_Elaboration_Entity_Required when requested to preserve
5261 control flow, to ensure the unit elaboration is materialized at
5262 bind time, resulting in the inclusion of the unit object file
5263 in the executable closure at link time.
5265 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5267 * exp_dbug.adb: In Debug_Renaming_Declaration,
5268 when dealing with indexed component, accept to produce a renaming
5269 symbol when the index is an IN parameter or when it is a name
5270 defined in an outer scope.
5272 2017-04-25 Yannick Moy <moy@adacore.com>
5274 * errout.adb (Error_Msg): Adapt continuation
5275 message in instantiations and inlined bodies for info messages.
5277 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5279 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5280 Use direct 4-character slice comparisons.
5282 pragma Inline. (Has_Suffix): Delete.
5283 (Is_Internal_File_Name):
5284 Test Is_Predefined_File_Name first.

5289 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5291 * checks.adb (Insert_Valid_Check): Code cleanup.
5292 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5293 (Expand_Actuals): Generate proper copy-back for a validation
5294 variable when it acts as the argument of a type conversion.
5295 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5296 predicate to operate on type qualifications.
5298 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5300 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5303 2017-04-25 Bob Duff <duff@adacore.com>
5305 * sem_prag.adb (No_Return): Give an error if the pragma applies
5306 to a body. Specialize the error for the specless body case,
5307 as is done for (e.g.) pragma Convention.
5308 * debug.adb: Add switch -gnatd.J to disable the above legality
5309 checks. This is mainly for use in our test suite, to avoid
5310 rewriting a lot of illegal (but working) code. It might also
5311 be useful to customers. Under this switch, if a pragma No_Return
5312 applies to a body, and the procedure raises an exception (as it
5313 should), the pragma has no effect. If the procedure does return,
5314 execution is erroneous.
5316 2017-04-25 Bob Duff <duff@adacore.com>
5318 * exp_ch6.adb (Expand_Actuals): This is the
5319 root of the problem. It took N as an 'in out' parameter, and in
5320 some cases, rewrote N, but then set N to Original_Node(N). So
5321 the node returned in N had no Parent. The caller continued
5322 processing of this orphaned node. In some cases that caused a
5323 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5324 and trips over the Empty Parent). The solution is to make N an
5325 'in' parameter. Instead of rewriting it, return the list of
5326 post-call actions, so the caller can do the rewriting later,
5327 after N has been fully processed.
5328 (Expand_Call_Helper): Move most of Expand_Call here. It has
5329 too many premature 'return' statements, and we want to do the
5330 rewriting on return.
5331 (Insert_Post_Call_Actions): New procedure to insert the post-call
5332 actions in the appropriate place. In the problematic case,
5333 that involves rewriting N as an Expression_With_Actions.
5334 (Expand_Call): Call the new procedures Expand_Call_Helper and
5335 Insert_Post_Call_Actions.
5337 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5339 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5340 properly type derived from generic formal types, to handle
5341 properly modified version of ACATS 4.1B B611017.
5343 2017-04-25 Javier Miranda <miranda@adacore.com>
5345 * exp_unst.adb (Subp_Index): Adding missing
5346 support for renamings and functions that return a constrained
5347 array type (i.e. functions for which the frontend built a
5348 procedure with an extra out parameter).
5350 2017-04-25 Pascal Obry <obry@adacore.com>
5352 * s-string.adb: Minor code clean-up.
5354 2017-04-25 Bob Duff <duff@adacore.com>

5361 2017-04-25 Bob Duff <duff@adacore.com>
5363 * prep.adb (Preprocess): Remove incorrect
5364 Assert. Current character can be ASCII.CR.
5366 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5368 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5369 convention Stdcall, which has a number of exceptions. Convention
5370 is legal on a component declaration whose type is an anonymous
5371 access to subprogram.
5373 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5375 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5376 (Try_One_Prefix_Interpretation): Use the base type when dealing
5377 with a subtype created for purposes of constraining a private
5378 type with discriminants.
5380 2017-04-25 Javier Miranda <miranda@adacore.com>

5384 dispatching primitives (Restore_Warnings): Restore warning on
5385 late dispatching primitives (Save_Warnings): Save warning on late
5386 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5387 to enable/disable this warning.
5388 (WA_Warnings): Set warning on late dispatching primitives.
5389 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5390 that its parent type has a private extension.
5391 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5393 * usage.adb: Document -gnatw.j and -gnatw.J.
5395 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5397 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5400 2017-04-25 Bob Duff <duff@adacore.com>
5402 * binde.adb (Validate): Do not pass dynamic strings
5403 to pragma Assert, because older compilers do not support that.
5405 2017-04-25 Bob Duff <duff@adacore.com>
5407 * s-fileio.adb (Close): When a temp file is
5408 closed, delete it and clean up its Temp_File_Record immediately,
5409 rather than waiting until later.
5410 (Temp_File_Record): Add File
5411 component, so Close can know which Temp_File_Record corresponds
5412 to the file being closed.
5413 (Delete): Don't delete temp files,
5414 because they are deleted by Close.
5415 (Open): Set the File component
5416 of Temp_File_Record. This requires moving the creation of the
5417 Temp_File_Record to the end, after the AFCB has been created.
5419 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5421 * checks.adb (Insert_Valid_Check): Do not generate
5422 a validity check when inside a generic.

5436 concerning inheritance of class-wide preconditions do not apply
5439 2017-04-25 Bob Duff <duff@adacore.com>
5441 * s-ficobl.ads: Minor comment fix.
5443 2017-04-25 Yannick Moy <moy@adacore.com>
5445 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5446 conversions from float to integer in GNATprove mode.
5447 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5448 to call Apply_Type_Conversion_Checks, so that range checks
5449 are properly positioned when needed on conversions, including
5450 when converting from float to integer. (Determine_Range): In
5451 GNATprove mode, take into account the possibility of conversion
5452 from float to integer.
5453 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5454 check on conversions from fixed-point to integer, not anymore
5455 on conversions from floating-point to integer, when in GNATprove
5458 2017-04-25 Yannick Moy <moy@adacore.com>
5460 * checks.adb (Determine_Range_R): Special case type conversions
5461 from integer to float in order to get bounds in that case too.
5462 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5463 mode, for computations involved in interval checking.

5477 * exp_attr.adb (Make_Range_Test): Add processing for validation
5478 variables to avoid extra reads and copies of the prefix.
5479 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5480 variables in order to reflect any changes done in the variable
5481 back into the original object.
5482 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5483 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5489 generate Finalize_Address routines for CodePeer.
5491 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5493 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5494 Analyze_Pre_Post_Condition, to implement the legality checks
5495 mandated by AI12-0131: Pre'Class shall not be specified for an
5496 overriding primitive subprogram of a tagged type T unless the
5497 Pre'Class aspect is specified for the corresponding primitive
5498 subprogram of some ancestor of T.
5500 2017-04-25 Bob Duff <duff@adacore.com>
5502 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5503 is redundant, set its Used_Operations to empty. This is only
5504 necessary for use clauses that appear in the parent of a generic
5505 child unit, because those use clauses get reanalyzed when we
5506 instantiate the generic, and we don't want the Used_Operations
5507 carried over from the original context (where it was probably
5510 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5512 * exp_ch6.adb: Minor reformatting.

5523 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5525 * sem_ch8.adb (Find_Type): For an attribute reference
5526 'Class, if prefix type is synchronized and previous errors
5527 have suppressed the creation of the corresponding record type,
5528 create a spurious class-wide for the synchonized type itself,
5529 to catch other misuses of the attribute
5531 2017-04-25 Steve Baird <baird@adacore.com>
5533 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5534 is True, then don't generate the accessibility check for the
5535 tag of a tagged result.

5537 if CodePeer_Mode is True, then don't generate the
5538 tag checks for the result of call to an instance of
5539 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5540 descendant of" check and the accessibility check).
5542 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5544 * sem_ch13.adb: Code cleanups.
5545 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

5550 * exp_ch4.adb (Library_Level_Target): New function.
5551 (Expand_Concatenate): When optimization is enabled, also expand
5552 the operation out-of-line if the concatenation is present within
5553 the expression of the declaration of a library-level object and
5554 not only if it is the expression of the declaration.
5556 2017-04-25 Bob Duff <duff@adacore.com>
5558 * freeze.adb (Freeze_Object_Declaration): Do
5559 not Remove_Side_Effects if there is a pragma Linker_Section,
5560 because in that case we want static initialization in the
5561 appropriate section.
5563 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5565 * exp_dbug.adb: Minor rewording and reformatting.

5569 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5570 handle the proposed changes to rules concerning potentially
5571 unevaluated expressions, to include selected components that
5572 do not depend on discriminants, and indexed components with
5574 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5575 predicate in quantified expression, and fix bugs in the handling
5576 of case expressions and membership test.
5577 (Analyze_Attribute_Old_Result): use new predicate.

5618 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5619 internal calls that appear in preconditions of protected
5620 operations, in default values for same, and in contract guards
5621 for contract cases in SPARK.
5623 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5625 * a-numaux.ads: Fix description of a-numaux-darwin

5632 * a-numaux-x86.ads: Fix package description.
5633 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5634 (Reduce): Adjust and complete description. Call Is_Nan instead of
5635 testing manually. Use an integer temporary to hold rounded value.
5636 * a-numaux-darwin.adb (Reduce): Likewise.
5637 (Is_Nan): New function.
5639 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5641 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5642 on analysis of prefix whose type is a current instance of a
5643 synchronized type, but where the prefix itself is an entity that

5648 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5649 the identity of callable entities therein, because they have been
5650 properly resolved, and prefixed calls may have been rewritten
5653 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5655 * exp_ch3.adb (Build_Init_Statements): Convert
5656 the expression of the pragma/aspect Secondary_Stack_Size to

5658 it to the Secondary_Stack_Size component of the task type's
5659 corresponding record.

5664 (etc) optimizations when the type is modular and the offsets
5667 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5669 * s-osinte-freebsd.ads: Minor comment tweaks
5671 2017-04-25 Javier Miranda <miranda@adacore.com>
5673 * urealp.adb (UR_Write): Reverse previous patch
5674 adding documentation on why we generate multiplications instead
5675 of divisions (needed to avoid expressions whose computation with
5676 large numbers may cause division by 0).
5678 2017-04-25 Bob Duff <duff@adacore.com>
5680 * erroutc.adb (Set_Specific_Warning_Off,
5681 Set_Warnings_Mode_Off): Use the correct source file for
5682 Stop. Was using Current_Source_File, which is only valid during
5683 parsing. Current_Source_File will have a leftover value from
5684 whatever file happened to be parsed last, because of a with_clause
5687 2017-04-25 Bob Duff <duff@adacore.com>
5689 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5690 to In_Predefined_Unit, but including GNAT units.
5691 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5692 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5693 because Should_Ignore_Pragma was not working reliably outside
5694 the parser, because Current_Source_File is not valid.
5695 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5696 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5733 Build_Invariant_Procedure_Body.
5734 (Build_Invariant_Procedure_Body):
5735 Remove refactored calls and integrated code from
5736 Add_Parent_Invariants and Add_Interface_Invariants.
5738 2017-04-25 Johannes Kanig <kanig@adacore.com>
5740 * errout.adb (Output_Messages): Adjust computation of total
5742 * erroutc.adb (Error_Msg): In statistics counts, deal
5743 correctly with informational messages that are not warnings.

5760 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5763 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5765 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5766 of prefix whose type is a current instance of a synchronized
5767 type. If the prefix is an object this is an external call (or
5768 requeue) that can only access public operations of the object. The
5769 previous predicate was too restrictive, and did not allow public
5770 protected operations, only task entries.
5772 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5774 * sem_ch5.adb, fname.adb: Minor reformatting.
5776 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5778 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5779 * einfo.ads Update the placement of
5780 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5782 (Is_Anonymous_Access_Type): New routine.
5783 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5784 master for an access type subject to pragma No_Heap_Finalization.
5785 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5786 allocated or deallocated does not finalization actions if the
5787 associated access type is subject to pragma No_Heap_Finalization.
5788 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5789 * par-prag.adb Pragma No_Heap_Finalization does not need special
5790 processing from the parser.
5791 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5792 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5793 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5794 No_Heap_Finalization.
5795 (Analyze_Pragma): Add processing for
5796 pragma No_Heap_Finalization. Update various error messages to
5797 use Duplication_Error.
5798 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5799 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5800 and corresponding pragma id.
5802 2017-04-25 Bob Duff <duff@adacore.com>
5804 * freeze.adb (Freeze_Record_Type): Use the
5805 underlying type of the component type to determine whether it's
5806 elementary. For representation clause purposes, a private type
5807 should behave the same as its full type.
5808 * fname.ads, fname.adb (Is_Predefined_File_Name):
5809 Make sure things like "system.ali" are recognized as predefined.
5811 2017-04-25 Javier Miranda <miranda@adacore.com>

5817 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5818 element iterator when the name is an overloaded function call,
5819 one of whose interpretations yields an array.
5821 2017-04-25 Bob Duff <duff@adacore.com>
5823 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5824 Is_Internal_Unit_Name): New functions for operating on unit
5825 names, as opposed to file names. There's some duplicated code
5826 with fname.adb, which is unfortunate, but it seems like we don't
5827 want to add dependencies here.
5828 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5829 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5830 is not a file name at all.
5831 * fname.ads, fname.adb: Document the fact that
5832 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5833 for ALI files, and fix the code so it works properly for ALI
5834 files. E.g. these should return True for "system.ali".
5836 2017-04-25 Justin Squirek <squirek@adacore.com>
5838 * exp_util.adb (Add_Invariant): Removed,
5839 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5840 and Add_Own_Invariant. (Add_Invariant_Check): Used
5841 for adding runtime checks from any kind of invariant.
5842 (Add_Inherited_Invariant): Generates invariant checks for
5843 class-wide invariants (Add_Interface_Invariants): Removed, code
5844 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

5846 Removed, code moved to Build_Invariant_Procedure_Body
5847 (Build_Invariant_Procedure_Body): Add refactored calls
5848 and integrated code from Add_Parent_Invariants and
5849 Add_Interface_Invariants.
5850 (Process_Type): Removed, the
5851 relavant code was inlined into both Add_Own_Invariant and
5852 Add_Inherited_Invariant.
5854 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5856 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5873 and Build_Invariant_Procedure_Declaration.
5874 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5875 and Build_Invariant_Procedure_Declaration from exp_ch7
5876 and break-out Is_Untagged_Private_Derivation from
5877 Build_Invariant_Procedure_Body.
5878 (Replace_Type_References):
5879 Append an extra parameter to allow for dispatching replacements
5880 and add the corrasponding logic.
5881 (Type_Invariant): Remove
5882 Replace_Typ_Refs and replace its references with calls to
5883 Replace_Type_References.
5884 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5886 2017-04-25 Bob Duff <duff@adacore.com>
5888 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5889 that returns True when appropriate.
5890 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5891 when compiling predefined files.
5892 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5893 "gnat.adc" should not be considered a predefined file name.
5894 That required (or at least encouraged) a lot of cleanup of global
5895 variable usage. We shouldn't be communicating information via
5896 the global name buffer.
5897 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5898 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5903 * osint.adb (Find_File): Handle properly a request for a
5904 configuration file whose name is a directory.

5918 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5919 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5920 Add String_To_Name with no side effects.
5922 2017-04-25 Justin Squirek <squirek@adacore.com>
5924 * sem_ch3.adb (Analyze_Declarations): Add
5925 additional condition for edge case.

5929 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5930 reserved words inside pragmas. This is necessary to allow the
5931 pragma name Interface to be used in pragma Ignore_Pragma.

5934 2017-04-25 Javier Miranda <miranda@adacore.com>
5936 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

5957 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
5958 the first pass over an assignment statement with target names,
5959 to prevent the generation of subtypes (such as discriminated
5960 record components)that may carry the target name outside of the

5962 the assignment is reanalyzed in full.
5963 (Analyze_Target_Name): Handle properly class-wide types.

5995 properties of the private type to the full view in case the full
5996 view derives from a parent type and inherits a DIC pragma.
5997 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
5998 DIC pragma is placed at the top of a declarative region.
6000 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6002 * a-tasatt.adb: Complete previous change and use an unsigned
6003 int to avoid overflow checks.
6005 2017-04-25 Ed Schonberg <schonberg@adacore.com>

6008 the error message when the attribute reference is an actual in
6009 a call to a subprogram inherited from a generic formal type with
6010 unknown discriminants, which makes the subprogram and its formal
6011 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6013 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6015 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6018 2017-04-25 Bob Duff <duff@adacore.com>
6020 * sem_attr.adb (Type_Key): Add code in the
6021 recursive Compute_Type_Key to protect against fetching the source
6022 code for Standard, in case a component of the type is declared
6023 in Standard. There was already code to do this for the original
6024 type, but not for its components.
6026 2017-04-25 Javier Miranda <miranda@adacore.com>
6028 * exp_ch3.adb (Build_Initialization_Call): Handle
6029 subtypes of private types when searching for the underlying full
6030 view of a private type.

6045 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
6046 context is a package declaration.
6047 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
6048 Analyze_Generic_Package_Declaration): ditto.

6069 * s-memory.adb: Add a comment regarding efficiency.
6070 * atree.adb: Fix the assertion, and combine 2 assertions into one,

6722 (Check_Dependency_Clause): Properly detect a match between two
6723 'Result attributes. Update the various post-match cases to use

6727 (Remove_Extra_Clauses): New routine.
6728 (Report_Extra_Clauses): Remove the detection of ... => null

6733 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
6734 report on spurious overlaps between values involving a subtype
6735 with a static predicate, because the expansion of such a subtype

6787 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6788 an object declaration for an array type with a modular index type
6789 with the size of Long_Long_Integer. Special processing is needed
6790 in this case to compute reliably the size of the object, and
6791 eventually to raise Storage_Error, when wrap-around arithmetic
6792 might compute a meangingless size for the object.
6794 2017-01-23 Justin Squirek <squirek@adacore.com>

6801 * sem_res.adb (Resolve_Call): In the part of the code where
6802 it is deciding whether to turn the call into an indexed
6803 component, avoid doing so if the call is to an instance of
6804 Unchecked_Conversion. Otherwise, the compiler turns it into an
6805 indexed component, and resolution of that turns it back into a
6806 function call, and so on, resulting in infinite recursion.
6807 * sem_util.adb (Needs_One_Actual): If the first formal has a
6808 default, then return False.

6855 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6856 must be treated as delayed aspect even if the expression is

6910 returns a limited view of a type and at the point of the call the
6911 function is not declared in the extended main unit then replace
6912 it with the non-limited view, which must be available. If the
6913 called function is in the extended main unit then no action is
6914 needed since the back-end handles this case.

6928 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6929 base type differs from that of the completion and the private
6930 subtype is an itype (created for a constraint on an access

7118 statements within an element iterator loop are only analyzed
7119 agter the loop is rewritten. Within a generic the analysis must
7120 be performed in any case to complete name capture.
7122 2017-01-19 Bob Duff <duff@adacore.com>
7124 * sem_prag.adb (Analyze_Pragma): Check for ignored pragmas first,

7130 * exp_ch7.adb (Build_Invariant_Procedure_Body): Semi-insert the
7131 body into the tree for GNATprove by setting its Parent field. The

7135 declaration into the tree for GNATprove by setting its Parent
7137 * freeze.adb (Freeze_Arry_Type):In GNATprove mode, do not add

7139 so that the procedure can be used to check the array type
7141 (Freeze_Record_Type): In GNATprove mode, do
7142 not add the component invariants to the record type invariant
7143 procedure so that the procedure can be used to check the record
7144 type invariants if any.

7164 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7166 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
7167 type, ie. a type whose component is a character type, and the
7168 aggregate is positional, do not convert into a string literal
7169 if the index type is not an integer type, because the original
7170 type may be required in an enclosing operation.
7172 2017-01-19 Bob Duff <duff@adacore.com>
7174 * binde.adb, debug.adb: Enable new elaboration order algorithm
7175 by default. -dp switch reverts to the old algorithm.

7220 * exp_ch6.adb (Expand_Call): Remove side effects on
7221 actuals that are allocators with qualified expression since the
7222 initialization of the object is performed by means of individual
7223 statements (and hence it must be done before the call).
7225 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7227 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7228 (Build_Derived_Enumeration_Type): If the derived type inherits a
7229 dynamic predicate from its parent, the bounds of the type must
7230 freeze because an explicit constraint is constructed for the
7231 type and the corresponding range is elaborated now.
7233 2017-01-19 Arnaud Charlet <charlet@adacore.com>
7235 * sem_attr.ads: minor fix of inconsistent casing in comment
7236 * lib-writ.ads: minor align comments in columns

7261 public, for use elsewhere.
7262 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
7263 an Inlined_body, recognize a call that uses object notation

7267 2017-01-19 Bob Duff <duff@adacore.com>
7269 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
7270 in case of generic formal discrete types, because it causes crashes in

7278 2017-01-19 Bob Duff <duff@adacore.com>
7280 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
7281 Increment Warnings_Detected. It was decrementing, which is
7282 wrong since we just issued a warning message.
7283 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
7284 these variables to be of subtype Nat instead of Int, because
7285 they should never be negative.
7287 2017-01-19 Javier Miranda <miranda@adacore.com>
7289 * contracts.adb (Build_Postconditions_Procedure): Replace
7290 Generate_C_Code by Modify_Tree_For_C.

7312 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
7314 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
7316 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7318 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7319 selected component has a prefix that might be interpreted
7320 as a parameterless function call, but none of the candidate
7321 interpretations is parameterless, and there is a hidden homonym
7322 of the prefix that is a package.
7323 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7324 interpreted as a parameterless function call and its analysis
7325 fails, do not call Analyze_Selected_Component.
7327 2017-01-19 Steve Baird <baird@adacore.com>
7329 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7331 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7332 calls to a newly-defined Scalar_Range_Of_Right_View function.
7334 2017-01-19 Arnaud Charlet <charlet@adacore.com>

7339 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7340 from repeated code of Traverse_Compilation_Unit.
7341 (Traverse_Declaration_Or_Statement): fixed detection of
7342 generic subprograms and packages; also, iteration over case
7343 statement alternatives rewritten to avoid testing if the first
7344 alternative is present (since it must be present due to Ada
7345 syntax restrictions).
7347 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7349 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
7350 returning by reference not just for subprogram body stubs,

7360 identifier nodes that do not come from source, to handle properly
7361 dimensionality check within an inlined body which inclddes both
7362 original operands and rewritten operands. This removes spurious
7363 dimensionality errors in the presence of front-end inlining,
7364 as well as in SPARK mode.
7366 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7405 * scil_ll.adb: Minor style fix in comment.
7406 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
7407 even if entity is already set, because the node may be renalyzed
7408 after inlining transformations.

7437 * sem_ch6.adb (Cloned_Expression): New subprogram.
7438 (Freeze_Expr_Types): Complete previous patch since the expression
7439 of an expression-function may have iterators and loops with
7440 defining identifiers which, as part of the preanalysis of the
7441 expression, may be left decorated with itypes that will not be
7442 available in the tree passed to the backend.

7482 2017-01-13 Bob Duff <duff@adacore.com>
7484 * binde.adb (Elab_New): New elaboration order algorithm
7485 that is expected to cause fewer ABE issues. This is a work in
7486 progress. The new algorithm is currently disabled, and can be
7487 enable by the -dp switch, or by modifying the Do_Old and Do_New
7488 etc. flags and rebuilding. Experimental code is included to
7489 compare the results of the old and new algorithms.
7490 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7491 can have multiple of these tables, so the old and new algorithms
7493 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7494 parameter of type array. This avoids the global variable, and
7495 allows bounds checking (which is normally defeated by the tables
7496 packages). It also ensures that the Elab_Order is read-only
7498 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7499 subprograms that need it, as above.
7500 * debug.adb: Document new -dp switch. Modify doc of old -do
7502 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7503 and Bindgen. Move writing of closure (-R and -Ra switches)

7506 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7508 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7509 function is a completion, all entities referenced in the
7510 expression are frozen. As a consequence, a reference to an
7511 uncompleted private type from an enclosing scope is illegal.
7513 2017-01-13 Javier Miranda <miranda@adacore.com>
7515 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7516 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7517 expression function declaration that is a completion, its
7518 expression causes freezing (AI12-0103).
7520 2017-01-13 Vadim Godunko <godunko@adacore.com>
7522 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7576 Iterated_Component_Associations.
7577 (Gen_Loop): Generate proper loop for an
7578 Iterated_Component_Association: loop variable has the identifier
7579 of the original association. Generate a loop even for a single
7580 component choice, in order to make loop parameter visible in
7582 (Flatten): An Iterated_Component_Association is not static.

7603 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7605 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7606 mode a choice that is a subtype with a static predicate is
7607 replaced by the values it covers. This transformation must not
7608 be performed in ASIS mode, to preserve the source for analysis.
7610 2017-01-13 Justin Squirek <squirek@adacore.com>

7625 and resolve the discrete choices and the expression of the
7627 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7628 Loop_Actions and Box_Present are attributes of
7629 N_Iterated_Component_Association nodes. Box_Present is always
7631 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7632 has a Discrete_Choices list, as specified in the RM. A
7633 Component_Association for aggregate uses instead a Choices list.
7634 We have to live with this small inconsistency because the new

7665 (Expand_Inlined_Call): Ensure that a temporary
7666 is always created in the cases where a type conversion may be
7667 needed on an input parameter in GNATprove mode, so that GNATprove
7668 sees the check to perform.
7669 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7670 when not applicable due to actual requiring type conversion
7671 with possible check but no temporary value can be copied for
7672 GNATprove to see the check.
