303 to libgnat subdirectory.
305 2017-09-08 Yannick Moy <moy@adacore.com>
307 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
308 return the entity associated with the call.
309 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
310 Replace the internal Get_Function_Id with the new
311 Sem_Aux.Get_Called_Entity.
312 (Iterate_Call_Parameters): New
313 procedure to iterate on formals and actuals at the same time.
314 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
315 Set SPARK_Mode from spec when set, for analysis
316 of instance. Restore after analysis of instance.
317 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
318 set, for analysis of body instance. Restored automatically at
319 the end of the subprogram.
320 * gnat1drv.adb (Adjust_Global_Switches): Set
321 Check_Validity_Of_Parameters to False in GNATprove mode.
322 * opt.ads (Check_Validity_Of_Parameters): Document switch to
325 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
327 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
328 (New_Copy_Tree): ...there. Reset the hash tables only if they
329 were used in the previous invocation.
330 * s-htable.adb: Fix typo.
332 2017-09-08 Bob Duff <duff@adacore.com>
334 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
336 2017-09-08 Arnaud Charlet <charlet@adacore.com>
338 * sem_aggr.adb: minor style fix.
340 2017-09-08 Bob Duff <duff@adacore.com>
342 * sprint.adb (Write_Corresponding_Source): Ignore if there is
343 no current source file.
344 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
345 Print something helpful in case N is invalid.
346 * sprint.ads: Minor comment fix.
348 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
350 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
353 2017-09-08 Bob Duff <duff@adacore.com>
355 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
356 Ada_2020, along the same lines as the other Ada version pragmas.
358 2017-09-08 Gary Dismukes <dismukes@adacore.com>
360 * sem_ch12.adb: Minor typo fixes and reformatting.
362 2017-09-08 Yannick Moy <moy@adacore.com>
364 * sem_aggr.adb (Resolve_Record_Aggregate):
365 Rewrite bounds of aggregate subexpressions which may depend on
366 discriminants of the enclosing aggregate.
368 2017-09-08 Yannick Moy <moy@adacore.com>
370 * sem_ch5.adb: Prevent assertion failure on illegal code.
372 2017-09-08 Yannick Moy <moy@adacore.com>
374 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
375 calling Renamed_Entity on an entity which cannot be a renaming.
377 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
379 * exp_aggr.adb: Add with & use clause for Urealp.
380 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
381 elementary types instead of just discrete types.
382 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
383 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
384 Be prepared for the FP zero value in the memset case. Add small
387 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
389 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
392 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
394 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
395 of New_Copy because the latter leaves the syntactic structure of
396 the tree inconsistent (a child is accessible through two parents)
397 and prevents proper replication of itypes by subsequent calls
399 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
400 New_Copy because the latter leaves the syntactic structure of the
401 tree inconsistent (a child is accessible through two parents)
402 and prevents proper replication of itypes by subsequent calls
404 * sem_util.adb (In_Subtree): New routine.
405 (New_Copy_Tree): Reimplemented.
406 * sem_util.ads (In_Subtree): New routine.

409 2017-09-08 Ed Schonberg <schonberg@adacore.com>
411 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
412 for aspect Default_Value is a static scalar value, but it does
413 not freeze the type. Yhis allows for subsequent representation
414 clauses for the type.
416 2017-09-08 Javier Miranda <miranda@adacore.com>
418 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
419 not add entries into the undefined reference table when we are
420 compiling with errors ignored.
422 2017-09-08 Ed Schonberg <schonberg@adacore.com>
424 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
425 check if the instance is within an enclosing instance body. The
426 formal package was legal in the enclosing generic, and is
427 legal in the enclosing instantiation. This optimisation may be
428 applicable elsewhere, and it also removes spurious errors that
429 may arise with on-the-fly processing of instantiations that
430 contain Inline_Always subprograms.
432 2017-09-08 Vincent Celier <celier@adacore.com>
434 * gnatcmd.adb: Disregard empty argument of GNAT driver.
436 2017-09-08 Justin Squirek <squirek@adacore.com>
438 * checks.adb (Insert_Valid_Check): Manually decorate
439 the generated temporary for range valdity checks.
441 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
443 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
445 2017-09-08 Justin Squirek <squirek@adacore.com>
447 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
448 case to handle underscore flags.
449 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
450 new procedure to handle underscores.
452 2017-09-08 Javier Miranda <miranda@adacore.com>
454 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
455 divisions with fixed point results to avoid generating twice
456 the runtime check on divide by zero.
457 * checks.adb (Apply_Divide_Checks): Ensure that operands are
458 not evaluated twice (once for their runtime checks and once for
459 their regular computation).
461 2017-09-08 Yannick Moy <moy@adacore.com>
463 * sem_prag.adb (Analyze_Part_Of): Add missing
464 return statements after issuing errors. Add detection of
465 out-of-order item and single concurrent type.

566 s-objrea.adb, s-tsmona-linux.adb, s-tsmona-mingw.adb: New.
567 * gcc-interface/Makefile.in: Enable s-trasym-dwarf.adb on x86*linux.
569 2017-09-08 Bob Duff <duff@adacore.com>
571 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
572 New routine to read the Tag robustly.
573 * exp_attr.adb (Input): Change the expansion of 'Input,
574 in the class-wide case, to call String_Input_Tag instead of
577 2017-09-08 Arnaud Charlet <charlet@adacore.com>
579 * s-rident.ads (Restriction_Id): reorder enum
580 literals, so that Pure_Barriers is no longer in range of the
581 Cunit_Boolean_Restrictions subtype.
583 2017-09-08 Nicolas Roche <roche@adacore.com>
585 * a-taster.ads, a-taster.adb: Move to libgnarl
586 * gcc-interface/Makefile.in: Remove obsolete targets. Code cleanups.
587 Add support for files in libgnarl.

595 when the actual is a construct that involves a dereference of an
596 expression that includes a formal of the enclosing subprogram,
597 In such cases, the accessibility level of the actual is that of
598 the corresponding formal, which is passed in as an additional
599 actual in the outer call.
601 2017-09-08 Bob Duff <duff@adacore.com>
603 * exp_intr.adb (Add_Source_Info): Do not decode
604 file names; they were not encoded in the first place.
606 2017-09-08 Bob Duff <duff@adacore.com>
608 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
609 exceptions instead of crashes. Check for absurdly long strings
610 and empty strings. Empty strings cause trouble because they can
611 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
612 be empty, which causes an array index out of bounds.
613 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
616 2017-09-08 Arnaud Charlet <charlet@adacore.com>
618 * sem_util.adb (Is_CCT_Instance): allow use in

635 2017-09-08 Yannick Moy <moy@adacore.com>
637 * exp_attr.adb (Expand_Loop_Entry_Attribute): Do
638 not skip a loop coming from source which is rewritten into a loop.
640 2017-09-08 Ed Schonberg <schonberg@adacore.com>
642 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
643 wrapper has convention Ada, to prevent spurious warnings on
644 unconstrained array parameters.
646 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
648 * sem_prag.adb (Check_Variant): Use First_Non_Pragma/Next_Non_Pragma.

669 generating warning message.
671 2017-09-08 Ed Schonberg <schonberg@adacore.com>
673 * par-ch4.adb (P_Iterated_Component_Association): Place construct
674 under -gnat2020 flag, given that it is a future feature of
676 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
677 defining identifier as referenced to prevent spurious warnings:
678 corresponding loop is expanded into one or more loops whose
679 variable has the same name, and the expression uses those names
680 and not the original one.
682 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
684 * sem_elab.adb (Check_A_Call): Do not consider
685 references to internal variables for SPARK semantics.

704 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
706 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
707 Correction of the return type from access type to option type.
708 (Simple_HTable): Moving the Instance_Data to ads file.
710 2017-09-08 Yannick Moy <moy@adacore.com>

735 missing checks on the presence of Entity() before checking the
738 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
740 * sem_ch6.adb (Analyze_Expression_Function): Reorder some
741 statements, use local variable and remove unnecessary processing.

754 required for one of the new subprograms.
756 Invoke Make_Build_In_Place_Iface_Call_In_Anonymous_Context
757 (Expand_N_Extended_Return_Statement): Extend the
758 cases covered by an assertion on expected BIP object

761 Removing unused code; found working on this ticket.
762 (Make_Build_In_Place_Call_In_Object_Declaration): Move the code

772 subprogram Make_Build_In_Place_Iface_Call_In_Object_Declaration.
773 * exp_attr.adb (Expand_N_Attribute_Reference): Invoke the new
774 subprogram Make_Build_In_Place_Iface_Call_In_Anonymous_Context.

787 2017-09-08 Javier Miranda <miranda@adacore.com>
789 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
790 access to interface types. Remove also the accessibility check.
792 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
794 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
795 all the types that are referenced by the expression.
796 (Analyze_Expression_Function): Call Freeze_Expr_Types for
797 a completion instead of manually freezing the type of the
799 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
801 2017-09-08 Ed Schonberg <schonberg@adacore.com>
803 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
804 New procedure, auxiliary to Expand_Pragma_Check, to handle
805 references to the discriminants of a protected type within a
806 precondition of a protected operation. This is needed because
807 the original precondition has been analyzed in the context of
808 the protected declaration, but in the body of the operation
809 references to the discriminants have been replaved by references
810 to the discriminants of the target object, and these references
811 are only created when expanding the protected body.
813 2017-09-08 Yannick Moy <moy@adacore.com>
815 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
818 2017-09-08 Ed Schonberg <schonberg@adacore.com>
820 * exp_attr.adb (Build_Record_VS_Func): If the record is an
821 unchecked union, do not emit checks for its (non-existent)
822 discriminants, or for variant parts that depend on them.
824 2017-09-08 Justin Squirek <squirek@adacore.com>
826 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
827 Find_Comparison_Type.Try_One_Interp): Add check for generic
830 2017-09-08 Arnaud Charlet <charlet@adacore.com>
832 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
833 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
834 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
835 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
836 remaining references to AAMP_On_Target.
838 2017-09-08 Ed Schonberg <schonberg@adacore.com>

850 the underlying type to handle limited-withed types.
852 2017-09-08 Ed Schonberg <schonberg@adacore.com>
854 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
855 over a subtype of a type with a static predicate, taking into
856 account the predicate function of the parent type and the bounds
857 given in the loop specification.
858 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
859 a loop specification that is a subtype indication whose type mark
860 is a type with a static predicate, inherit predicate function,
861 used to build case statement for rewritten loop.
863 2017-09-08 Justin Squirek <squirek@adacore.com>
865 * lib-load.adb: Modify printing of error message to exclude file
868 2017-09-08 Arnaud Charlet <charlet@adacore.com>
870 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
871 don't inline subprograms declared in both visible and private
873 (In_Package_Spec): previously In_Package_Visible_Spec; now
874 detects subprograms declared both in visible and private parts
877 2017-09-08 Ed Schonberg <schonberg@adacore.com>
879 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
880 the type is an anonymous array in an object declaration, whose
881 component type has an invariant, use the object declaration
882 as the insertion point for the invariant procedure, given that
883 there is no explicit type declaration for an anonymous array type.
885 2017-09-08 Bob Duff <duff@adacore.com>
887 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

893 2017-09-08 Justin Squirek <squirek@adacore.com>
895 * lib-load.adb (Load_Main_Source): Add error output in the case a
896 source file is missing.
898 2017-09-08 Bob Duff <duff@adacore.com>
901 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
902 Default_WCEM by default (i.e. if the encoding is not specified
905 2017-09-08 Bob Duff <duff@adacore.com>
907 * s-trasym.ads (Hexa_Traceback): If
908 Suppress_Hex is True, print "..." instead of a hexadecimal
910 * s-trasym.adb: Ignore No_Hex in this version.
913 2017-09-08 Bob Duff <duff@adacore.com>
915 * debug.adb: Minor reformatting.
917 2017-09-08 Bob Duff <duff@adacore.com>
919 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the

924 * s-hibaen.ads: Remove obsolete file.
926 2017-09-08 Arnaud Charlet <charlet@adacore.com>

932 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
934 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
935 allow calls in the context of package spec (for pragma
936 Initializes) and bodies (for pragma Refined_State).
938 2017-09-08 Bob Duff <duff@adacore.com>
940 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
943 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
945 * debug.adb (dA): Adjust comment.
946 * gnat1drv.adb (Gnat1drv): Likewise.
947 * opt.ads (List_Representation_Info_Extended): New variable.
948 * repinfo.adb (List_Record_Info): Split implementation into...
949 (Compute_Max_Length): ...this. Recurse on records if requested.
950 (List_Record_Layout): Likewise.
951 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
952 statement, accept '0' and set List_Representation_Info_Extended
954 * usage.adb (Usage): Document new -gnatRe variant.
956 2017-09-08 Ed Schonberg <schonberg@adacore.com>
958 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
959 Do not save the given entity in the global variable Default_Pool
960 if the pragma appears within a generic unit.
962 2017-09-08 Bob Duff <duff@adacore.com>
964 * errout.adb (Delete_Warning): Do not
965 decrement Warnings_Treated_As_Errors. This is called before
966 Warnings_Treated_As_Errors has been incremented to account for
967 this warning. Decrementing it here can lead to negative values
968 of Warnings_Treated_As_Errors, raising Constraint_Error in
969 checks-on builds, and causing the compiler to return an error
970 code in checks-off builds.
972 2017-09-08 Arnaud Charlet <charlet@adacore.com>
974 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
975 entities of named concurrent types as Ref_Id and not of anonymous
976 concurrent objects (because callers already know when a conversion
977 is necessary and can easily do it); also, do not expect protected
978 types or protected objects as Context_Id (because no flow-related
979 SPARK pragmas are attached there); reflect these changes in a
980 more precise comment.
982 2017-09-08 Olivier Hainque <hainque@adacore.com>
984 * g-altive.ads: Add documentation.
986 2017-09-08 Bob Duff <duff@adacore.com>
988 * sem_util.ads, debug.adb: Minor comment fix.
989 * erroutc.ads: Comment fix.
991 2017-09-08 Ed Schonberg <schonberg@adacore.com>
993 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
994 for compatibility of component types of formal and actual in an
995 instantiation of a child unit, when the component type of the
996 formal is itself a formal of an enclosing generic.
998 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1000 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1001 sem_prag.adb to make it available for GNATprove; for concurrent
1002 types replace custom scope climbing with Scope_Same_Or_Within; for
1003 single concurrent objects add scope climbing (with Scope_Within),
1004 which was not there (that's the primary semantic change of this
1005 commit); also, when comparing a single concurrent object with
1006 its corresponding concurrent type rely on equality of types,
1007 not of objects (because that's simpler to code).
1008 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1009 (Analyze_Global_Item): adjust special-casing of references to the
1010 current instance of a concurrent unit in the Global contracts
1011 of task types and single tasks objects; similar for references
1012 in the protected operations and entries of protected types and
1013 single protected objects (in all these cases the current instance
1014 behaves as an implicit parameter and must not be mentioned in
1015 the Global contract).
1017 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1019 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1020 function calls returning a record within a subprogram call,
1023 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1025 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1026 name that designates the current instance of a child unit in its
1027 own body and appears as the prefix of a reference to an entity
1028 local to the child unit.
1029 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
1032 2017-09-08 Yannick Moy <moy@adacore.com>
1034 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that

1039 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
1040 warnings on internal units in configurable run time mode.
1042 2017-09-08 Bob Duff <duff@adacore.com>
1044 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
1045 representation items from interfaces that the derived type
1046 implements, not just from the parent type.
1047 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
1048 this to return an empty list when there are no interfaces.
1049 * einfo.ads, sem_ch13.adb: Minor comment fixes.
1050 * sem_attr.adb: Minor comment fix.
1052 2017-09-08 Doug Rupp <rupp@adacore.com>
1054 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
1057 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1059 * exp_ch4.adb (Expand_N_Allocator): Generate a
1060 call to Allocate_Any_Controlled when the allocation does not

1439 is now consulted not only for abstract states and variables,
1440 but for all kinds of items.
1441 (Collect_Subprogram_Inputs_Outputs): Do not process formal

1576 Elab_Old and use the order chosen by Elab_Old, possibly with
1577 debugging printouts comparing the two orders." Now it means
1578 "do not run Elab_New." This is of use if there are bugs that

1587 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
1588 reference to SPARK RM.
1590 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1592 * layout.adb: Use SSU short hand consistently throughout the file.

1596 * freeze.adb (Freeze_Record_Type)
1597 <Sized_Component_Total_Round_RM_Size>: New local variable to
1598 accumulate the rounded RM_Size of components. Update it for
1599 every component whose RM_Size is statically known. Add missing
1600 guard to check that bit packing is really required before issuing
1601 the error about packing. Swap condition for clarity's sake.
1602 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

1621 project manager sources.
1623 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1625 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1626 entity of a mutable type and the right-hand side is a conditional
1627 expression, resolve the alternatives of the conditional using
1628 the base type of the target entity, because the alternatives
1629 may have distinct subtypes. This is particularly relevant if
1630 the alternatives are aggregates.
1632 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1634 * checks.adb (Apply_Predicate_Check): If the expression is an
1635 aggregate that is the RHS of an assignment, apply the check to
1636 the LHS after the assignment, rather than to the aggregate. This
1637 is more efficient than creating a temporary for the aggregate,
1638 and prevents back-end crashes when the aggregate includes a
1639 dynamic "others' association.
1641 2017-09-06 Yannick Moy <moy@adacore.com>
1643 * sem_ch12.adb (Analyze_Instance_And_Renamings):

1645 of the generated package declaration.
1647 2017-09-06 Yannick Moy <moy@adacore.com>
1649 * sem_res.adb (Resolve_Call): Do not issue a
1650 message for calls inside expression function, unless body was
1651 seen and is candidate for inlining.
1653 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1655 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
1656 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
1657 body. do not freeze the formals of the generic unit.
1659 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1661 * errout.adb (Error_Msg): Separate the
1662 treatment for warning vs. style messages in inlinings and
1663 instantiations. Prevents blowups on calls to Warn_Insertion for
1664 style messages, which should not be called in that case because
1665 Warning_Msg_Char is not set.
1667 2017-09-06 Justin Squirek <squirek@adacore.com>
1669 * sem_prag.adb (Check_VFA_Conflicts): Created
1670 to group all Volatile_Full_Access checks relating to other
1671 representation pragmas (Mark_Component_Or_Object): Created
1672 to centeralize the flagging of attributes for the record type
1673 component case, a pragma applied individually to a component, and
1675 (Process_Atomic_Independent_Shared_Volatile):
1676 Add propagation of certain pragmas to record components and move
1677 evaluation of VFA checks

1690 2017-09-06 Bob Duff <duff@adacore.com>
1692 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1693 that is a proper body corresponding to a stub, we defer the
1694 adjustment of the sloc until after the correct adjustment has
1695 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1696 the adjustment, because it will be outside the range in (the old,
1697 incorrect) S_Adjustment.
1698 * inline.adb: Use named notation for readability and uniformity.
1699 * sinput-l.adb: Minor improvements to debugging output printed
1701 * sinput-l.ads (Create_Instantiation_Source): Minor comment
1704 2017-09-06 Vincent Celier <celier@adacore.com>

1708 2017-09-06 Sylvain Dailler <dailler@adacore.com>
1710 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a

1716 2017-09-06 Justin Squirek <squirek@adacore.com>
1718 * einfo.adb (Set_Linker_Section_Pragma): Modify
1719 Set_Linker_Section_Pragma to be consistant with the "getter"
1720 Linker_Section_Pragma.
1721 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1722 checking for container loops so that the index cursor is not
1723 directly changable by the user with the use of E_Loop_Parameter.
1724 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

1768 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
1769 Generate a freeze node for the actual of a formal package, if
1770 the actual is declared in the same unit and has a corresponding
1771 body, to prevent the current instance from being frozen before

1796 missing case of controlled generalized indexing.
1797 (Is_Source_Object): Use routine Strip to remove indirections.
1798 (Strip): New routine.
1800 2017-09-06 Bob Duff <duff@adacore.com>
1802 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1803 we include the proper header. Otherwise, we just declare the necessary
1804 things from the capabilities library. This is so we can build on
1805 machines without that library, while still enabling that library.
1806 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1807 simply return 0 if the library is not present, or not included

1823 has no parameter specification and no entry index, use the entry name
1824 as the end of the generated SCO statement.
1826 2017-09-06 Steve Baird <baird@adacore.com>
1828 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1829 uses of 'Image and related attributes as having side effects in
1830 order to avoid replicating such uses.
1831 * pprint.ads (Expression_Image) Add new generic formal flag
1832 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1833 (eventually) override the default.
1834 * pprint.adb (Expression_Image) If the new flag is set, then
1835 suppress the ".all" suffix when displaying a dereference whose
1836 prefix is a use of a value-capturing compiler temp of the sort
1837 generated by Expr_Util.Remove_Side_Effects .

1853 so that applies to any entity.
1855 2017-09-06 Yannick Moy <moy@adacore.com>
1857 * sem_ch3.adb (Derived_Type_Declaration): Use
1858 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1860 2017-09-06 Javier Miranda <miranda@adacore.com>
1862 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1865 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1867 * sem_dim.adb (Analyze_Dimension): In an instance, a type

1870 (Dimensions_Of_Operand): Ditto.
1872 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1874 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

1886 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
1887 Universal_Real and the context is a floating-point type, resolve

1895 2017-09-06 Yannick Moy <moy@adacore.com>
1897 * freeze.adb (Check_Inherited_Conditions): Rewriting
1898 of inherited preconditions and postconditions should only occur
1899 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1900 be confused with SPARK_Mode being On.
1902 2017-09-06 Yannick Moy <moy@adacore.com>

1916 * sem_ch7.adb: Add with clause for GNAT.HTable.
1917 (Entity_Table_Size): New constant.
1918 (Entity_Hash): New function.
1919 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1920 (Is_Subprogram_Ref): Rename into...
1921 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1922 the table instead of bailing out on them. Scan the value of constants
1923 if it is not known at compile time.
1924 (Contains_Subprograms_Refs): Rename into...
1925 (Scan_Subprogram_Refs): ...this.
1926 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1927 Is_Public flag on subprograms if they are not actually referenced.
1928 (Hide_Public_Entities): Beef up comment on the algorithm.
1929 Reset the table of subprograms on entry.
1931 2017-09-06 Yannick Moy <moy@adacore.com>

1985 2017-09-06 Bob Duff <duff@adacore.com>
1987 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
1988 check back to the body, because SPARK is not yet ready for

2016 * sem_type.adb (Interface_Present_In_Ancestor): Within an
2017 expression function, or within a spec expression (default value,
2018 etc) a reference to an incomplete type is legal: legality of

2022 2017-09-06 Gary Dismukes <dismukes@adacore.com>
2024 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

2036 we can use modern Ada in this package.
2037 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2038 Move Ada.Command_Line.Response_File to System.Response_File,
2039 and make Ada.Command_Line.Response_File into a rename of
2040 System.Response_File. This is to avoid having gnatbind depend
2041 Ada.Command_Line, which would damage the bootstrap process now
2042 that Ada.Command_Line contains modern Ada (the raise expression).
2043 * gnatbind.adb: Avoid dependence on
2044 Ada.Command_Line. Depend on System.Response_File instead
2045 of Ada.Command_Line.Response_File. Change one call to
2046 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2047 to Ada.Command_Line.Argument_Count to use Arg_Count.
2048 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
2050 2017-09-06 Bob Duff <duff@adacore.com>

2058 "Assert(False)" with "return Iter", because if an iterable

2060 overriding or inherited default iterator.
2062 2017-09-06 Yannick Moy <moy@adacore.com>
2064 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

2070 allowed on loop parameters.
2071 (Set_Status_Flag_Or_Transient_Decl): The attribute is now allowed
2073 (Write_Field15_Name): Update the output for
2074 Status_Flag_Or_Transient_Decl.
2075 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
2076 to loop parameters. Update the documentation of the attribute
2077 and the E_Loop_Parameter entity.

2187 not retrievable as selected components.
2189 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2191 * sem_util.adb (Needs_One_Formal): The first formal of such a

2231 not visible in the object.
2232 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2233 side may be derived from that of the left-hand side (as in the
2234 case of an assignment with a change of representation) so the
2235 discriminant to be used in the retrieval of the value of the
2236 component must be the entity in the type of the right-hand side.

2811 * exp_ch6.adb (Expand_Call_Helper): When locating the
2812 accessibility entity created for an access parameter, handle
2813 properly a reference to a formal of an enclosing subprogram. if
2814 the reference appears in an inherited class-wide condition, it
2815 is the rewriting of the reference in the ancestor expression,
2816 but the accessibility entity must be that of the current formal.
2818 2017-05-02 Javier Miranda <miranda@adacore.com>
2820 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

2856 procedure body for a local (sub)type declaration within a
2857 predicate function. Invariant checks do not apply to these, and
2858 the expansion of the procedure will happen in the wrong scope,
2859 leading to misplaced freeze nodes.
2861 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2863 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2864 to analyze generated actions. If the main unit is a body,

2869 * einfo.adb (Declaration_Node): flip branches of

2900 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2901 Refine predicate for the case where the primitive operation
2902 is a renaming of equality. An overriding operation that is
2903 a user-defined renaming of predefined equality inherits its
2904 slot from the overridden operation. Otherwise it is treated
2905 as a predefined op and occupies the same predefined slot as
2906 equality. A call to it is transformed into a call to its alias,
2907 which is the predefined equality. A dispatching call thus uses
2908 the proper slot if operation is further inherited and called
2909 with class-wide arguments.
2911 2017-05-02 Justin Squirek <squirek@adacore.com>
2913 * errout.adb (Set_Msg_Text): Add a case to switch the message

2946 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2947 statement if the initialization call is a null procedure, as
2948 can happen with a controlled type with no explicit Initialize
2949 procedure, or an array of such.

2951 controlled components that has a trivial Initialize procedure,
2952 insert declaration for finalization counter after object

2955 finalization block and attendant declarations if component has
2956 a trivial Initialize procedure.

2958 a trivial Initialize procedure.

2988 2017-05-02 Gary Dismukes <dismukes@adacore.com>
2990 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
2991 parameter Array_Comp to indicate the case of an array object
2992 with null-excluding components.
2993 * checks.adb (Null_Exclusion_Static_Checks):
2994 Call Compile_Time_Constraint_Error instead of
2995 Apply_Compile_Time_Constraint_Error in the component case. Also
2996 call that when Array_Comp is True, with an appropriate warning for
2997 the array component case. Only create an explicit initialization
2998 by null in the case of an object of a null-excluding access type
2999 (and no longer do that in the component case).
3000 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3001 Array_Comp defaulted to False. Pass Empty for the Comp
3002 actual when calling Null_Exclusion_Static_Checks in the case
3003 where Comp_Decl matches Object_Decl, because we don't have a
3004 component in that case. In the case of an object or component
3005 of an array type, pass True for Array_Comp on the recursive call

3010 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3011 compute the linux priority from the Ada priority. Call this everywhere
3012 required. In particular, the previous version was not doing this
3013 computation when setting the ceiling priority in various places. It
3014 was just converting to C.int, which results in a ceiling that is off
3017 2017-05-02 Ed Schonberg <schonberg@adacore.com>

3036 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3037 here from exp_ch9, to recognize objects whose creation requires
3038 dynamic allocation, so that the proper warning can be emitted
3039 when restriction No_Implicit_Heap_Allocation is in effect.

3090 a discriminant check when the associated type is a constrained
3091 subtype created for an unconstrained nominal type.
3092 * exp_attr.adb: Minor reformatting.
3094 2017-05-02 Bob Duff <duff@adacore.com>

3106 operator /= into negation of operator = when needed.
3107 (Expand_SPARK): Call new
3108 function to expand operator /=.
3110 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3112 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3113 Simplify the expression for a fixed-fixed division to remove
3114 divisions by constants whenever possible, as an optimization
3115 for restricted targets.
3117 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3119 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3121 2017-05-02 Bob Duff <duff@adacore.com>
3123 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3124 to find primitive ops, instead of using an Identifier that will
3125 later be looked up. This is necessary because these ops are not
3126 necessarily visible at all places where we need to call them.
3127 * exp_util.ads: Minor comment fix.
3129 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3131 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3132 references are fully conformant if they are both expansions
3133 of the discriminant of a protected type, within one of the
3134 protected operations. One occurrence may be expanded into a
3135 constant declaration while the other is an input parameter to
3136 the corresponding generated subprogram.

3140 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3141 recursivly searching composite-types for null-excluding access
3142 types and verifying them.
3143 (Analyze_Object_Declaration): Add a
3144 call to Check_Null_Excluding_Components for static verification
3145 of non-initialized objects.
3146 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3147 a parameter for a composite-type's component and an extra case
3148 for printing component information.

3152 * sem_ch10.adb (Analyze_Subunit): Take
3153 configuration pragma into account when restoring appropriate
3154 pragma for analysis of subunit.

3166 array components specially.
3168 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3170 * sem_ch8.adb (Premature_Usage): If the premature usage of
3171 an entity is as the expression in its own object decaration,
3172 rewrite the reference as Any_Id to prevent cascaded errors or
3173 compiler loops when such an entity is used in an address clause.
3175 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3177 * gcc-interface/decl.c (components_to_record): Add missing guard.

3182 Put back pending fields onto the regular list if the misalignment
3183 happens to cancel itself.
3185 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3187 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3188 controlling actual in a prefixed call, preserve the original node
3189 information if the prefix itself has been rewritten, for ASIS use.
3191 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3193 * exp_ch6.adb (Insert_Post_Call_Actions):
3194 Code clean up. Insert the post-call actions after an enclosing
3195 procedure call when N denotes a function call and appears as an
3196 actual parameter in the procedure call.
3198 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3200 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3201 for the component, also reject the attribute if the component
3202 doesn't end on a byte boundary and its scalar storage order is
3203 different from that of the enclosing record type.
3205 2017-04-28 Javier Miranda <miranda@adacore.com>
3207 * atree.ads (Info_Messages): Removed.

3237 2017-04-28 Bob Duff <duff@adacore.com>
3239 * sem_util.ads, sem_util.adb (Might_Raise): New function
3240 that replaces Is_Exception_Safe, but has the opposite
3241 sense. Is_Exception_Safe was missing various cases -- calls inside
3242 a pragma Debug, calls inside an 'if' or assignment statement,
3243 etc. Might_Raise now walks the entire subtree looking for things
3245 * exp_ch9.adb (Is_Exception_Safe): Remove.
3246 (Build_Protected_Subprogram_Body): Replace call to
3247 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3248 constants where possible).
3249 * exp_ch7.adb: Rename Is_Protected_Body -->
3250 Is_Protected_Subp_Body. A protected_body is something different
3253 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

3279 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3280 Interrupt_Handler and Attach_Handler): Generate reference
3281 to protected operation to prevent spurious warnings about
3282 unreferenced entities. Previous scheme failed with style checks
3285 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3287 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3288 that follows an expression function must not be relocated to
3289 the generated body, because it applies to the code that follows.
3291 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3293 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3294 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3295 code that might violate the more stringent checking for 'Access
3296 introduced in Ada 2005.
3298 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3300 * a-cforse.adb: minor style fix in comment.
3302 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3304 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3305 initialize Block_Decls variable.
3306 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3307 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

3316 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3318 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3320 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3321 node between access types, freeze the designated type as well,
3322 so that dispatch table pointers are created in the proper scope,
3323 and not in the constructed body of the expression function.
3325 2017-04-28 Bob Duff <duff@adacore.com>
3327 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3328 value makes large compilations faster, but small compilations slower.
3330 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3332 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3334 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3336 * erroutc.adb (Compilation_Errors): Do not consider info messages
3337 as suitable warnings when warnings must be treated as errors.
3338 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3339 internally-generated packages when outputting completion
3341 * errout.adb (Output_Messages): Do not consider info messages as

3344 suitable warnings when warnings must be treated as errors.
3346 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3348 * warnsw.ads: Minor fix for incorrect wording in comment.
3350 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3352 * sem_res.adb (In_Instance_Code): New predicate in
3353 Valid_Conversion, to determine whether a type conversion appears
3354 as (or within) an actual for a formal object. Type conversions
3355 in instances are not rechecked in Valid_Conversion because
3356 visibility changes between generic location andi instance may
3357 lead to spurious errors, but conversions within an actual must be
3358 fully checked, and they are not fully resolved when pre-analyzing
3361 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3363 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3364 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3365 of the relocated node will have mangled Parent pointers.
3366 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3367 tables used in conjunction with entity and itype replication.
3368 (Visit_Entity): Rewrite the restriction on which entities
3369 require duplication. The restriction now includes all types.

3403 (Restore_Warnings): Likewise.
3404 (Save_Warnings): Likewise.
3405 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3406 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3407 components_to_record.
3408 (gnu_field_to_gnat): New function.
3409 (warn_on_field_placement): Likewise.
3410 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3411 parameters. Rename local variables and adjust recursive call.
3412 Rework final scan of the field list and implement warnings on the
3413 problematic placement of specific sorts of fields.
3415 2017-04-27 Bob Duff <duff@adacore.com>
3417 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

3422 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3423 For efficiency, cache results of Is_Internal_File_Name and
3424 Is_Predefined_File_Name in the Units table. This avoids a lot
3425 of repeated text processing.
3427 2017-04-27 Emmanuel Briot <briot@adacore.com>
3429 * g-comlin.adb (Sort_Sections): remove useless test.
3431 2017-04-27 Claire Dross <dross@adacore.com>
3433 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3434 allow the use of regular equality over elements in contracts.
3435 (Formal_Model): Ghost package containing model functions that are
3436 used in subprogram contracts.
3437 (Current_To_Last): Removed, model functions should be used instead.
3438 (First_To_Previous): Removed, model functions should be used instead.
3439 (Strict_Equal): Removed, model functions should be used instead.
3440 (No_Overlap): Removed, model functions should be used instead.
3441 (Equivalent_Keys): Functions over cursors are removed. They were
3442 awkward with explicit container parameters.
3443 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3444 allow the use of regular equality over elements in contracts.
3445 (Formal_Model): Ghost package containing model functions that

3454 * gnat1drv.adb: Code cleanup.
3456 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3458 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3459 attribute reference in a post- condition is the subprogram to
3460 which the condition applies. If the condition is inherited
3461 by a type extension, the prefix becomes a reference to the
3462 inherited operation, but there is no need to create a wrapper
3463 for this operation, because 'Result is expanded independently
3464 when elaborating the postconditions.
3466 2017-04-27 Bob Duff <duff@adacore.com>
3468 * sinput.adb: Minor code cleanup.
3469 * namet.adb (Append): Create faster versions of
3470 Append(String) and Append(Name_Id) by using slice assignment
3472 * sem_util.adb (In_Instance): Speed this up by removing
3473 unnecessary tests; Is_Generic_Instance is defined for all
3475 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3476 Remove unused function.
3477 * alloc.ads (Nodes_Initial): Use a much larger value, because
3478 the compiler was spending a lot of time copying the nodes table
3479 when it grows. This number was chosen in 1996, so is rather out
3480 of date with current memory sizes. Anyway, it's virtual memory.
3481 Get rid of Orig_Nodes_...; use Node_... instead.
3482 * atree.adb (Lock): Do not release the Nodes tables; it's a
3484 Orig_Nodes_ ==> Nodes_
3485 * nlists.adb: Orig_Nodes_ ==> Nodes_
3486 * g-table.adb: Remove unused "with" clause.
3487 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3488 not be used by clients.
3489 * g-dyntab.adb (Last_Allocated): New function
3490 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3492 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3494 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3496 (Subtypes_Statically_Match): Remove duplicate check.

3513 for qualified expressions, type conversions, and unchecked
3515 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
3516 processing for Ada 83 and instances.
3517 (Object_Access_Level): Merge the processing for indexed components
3518 and selected components.
3519 * uname.adb (Add_Node_Name): Merge the processing for stubs.

3529 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
3530 of Expand_Dispatching_Call. If the denoted subprogram has a
3531 class-wide precondition, this is the only precondition that
3532 applies to the call, rather that the class-wide preconditions
3533 that may apply to the body that is executed. (This is specified
3536 2017-04-27 Yannick Moy <moy@adacore.com>
3538 * gnat1drv.adb (Adjust_Global_Switches): Issue
3539 a warning in GNATprove mode if the runtime library does not
3540 support IEEE-754 floats.
3542 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3544 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
3545 is itself inherited it does not carry any contract information,
3546 so examine its parent operation which is its Alias.
3548 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3550 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3551 prefix can be an object reference in which case Obj'Image (X)
3552 can only be interpreted as an indexing of the parameterless
3553 version of the attribute.
3554 * par-ch4.adb (P_Name): An attribute reference can be the prefix of

4063 operations, constructors and properties. Universally quantified
4064 formulas in contracts are factorized in independant functions
4065 with a name and a comment. Names of parameters are improved.
4067 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4069 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4071 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4073 * sem_res.adb (Resolve_Type_Conversion): Do not
4074 install a predicate check here since this is already done during
4075 the expansion phase. Verify whether the operand satisfies the
4076 static predicate (if any) of the target type.
4077 * sem_ch3.adb (Analyze_Object_Declaration): Do
4078 not install a predicate check if the object is initialized by
4079 means of a type conversion because the conversion is subjected

4103 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
4104 in gnat1 and gnatbind.
4105 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4106 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4114 modifications in functional containers.
4115 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4116 to improve readablity. Subprograms are separated between basic
4117 operations, constructors and properties. Universally quantified
4118 formulas in contracts are factorized in independant functions
4119 with a name and a comment. Names of parameters are improved.
4121 2017-04-27 Gary Dismukes <dismukes@adacore.com>

4145 a-cofuma.ads, a-cofuba.adb, a-cofuba.ads: Minor reformatting.
4147 2017-04-27 Tristan Gingold <gingold@adacore.com>
4149 * s-excmac-gcc.ads, s-excmac-gcc.adb,
4150 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
4153 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4155 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4156 the loop which detects potential enclosing transient scopes. The
4157 loop now terminates much earlier as transient scopes are bounded
4158 by packages and subprograms.
4160 2017-04-27 Claire Dross <dross@adacore.com>
4162 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4163 allow the use of regular equality over elements in contracts.
4164 (Cursor): Type is now public so that it can be used in
4166 (Formal_Model): Ghost package containing
4167 model functions that are used in subprogram contracts.
4168 (Current_To_Last): Removed, model functions should be used
4170 (First_To_Previous): Removed, model functions should
4172 (Strict_Equal): Removed, model functions
4173 should be used instead.
4174 (Append): Default parameter value
4175 replaced by new wrapper to allow more precise contracts.

4189 * exp_spark.adb (Expand_SPARK): Perform specialized expansion
4190 for object declarations.
4191 (Expand_SPARK_N_Object_Declaration): New routine.

4193 Default_Initial_Condition procedure of a type under the SPARK
4194 elaboration checks umbrella.
4196 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4198 * sem.adb (Analyze): Diagnose an illegal iterated component
4200 * sem_util.ads, sem_util.adb

4205 * adaint.c (__gnat_get_current_dir): Return 0 in length if
4207 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4208 exception if getcwd failed.

4213 entities with special prefix.
4215 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4217 * debug.adb Change the documentation of switch -gnatd.s.
4218 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4219 to manage the secondary stack when an enclosing scope already
4220 performs this functionality (aka relaxed management). Switch
4221 -gnatd.s may be used to force strict management in which case
4222 the block will manage the secondary stack unconditionally. Add
4223 a guard to stop the traversal when encountering a package or a
4226 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4228 * sem_res.adb (Resolve_Call): Refine further the handling of
4229 limited views of return types in function calls. If the function
4230 that returns a limited view appears in the current unit,
4231 we do not replace its type by the non-limited view because
4232 this transformation is performed int the back-end. However,
4233 the type of the call itself must be the non-limited view, to
4234 prevent spurious resolution errors.
4236 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4238 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4239 Removed, proposed implementation using generics for class-wide
4240 preconditions proved impractical.
4241 (Class_Wide_Clone): New attribute of subprogram. Designates
4242 subprogram created for primitive operations with class-wide
4243 pre/postconditions that contain calls to other primitives. The
4244 clone holds the body of the original primitive, but the
4245 pre/postonditions do not apply to it. The original body is
4246 rewritten as a wrapper for a call to the clone.
4247 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4248 the flag is set, no code for the corresponding pre/postconditions
4249 is inserted into its body.
4251 2017-04-27 Bob Duff <duff@adacore.com>
4253 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
4254 Scalar_Storage_Order if -gnatI is given.
4255 * sem_prag.adb (Analyze_Pragma): Ignore

4264 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
4265 (Remove): New function that removes an element from a set.
4266 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
4267 (Remove): New function that removes an element from a sequence.
4268 (Insert): New function that adds anywhere in a sequence.

4281 of attribute 'Result is not considered a violation of pragma
4284 2017-04-27 Justin Squirek <squirek@adacore.com>
4286 * cstand.adb (Create_Standard): Correctly set
4287 Directly_Designated_Type for Any_Access.

4297 private child of Ada.Containers used to implement all functional
4299 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4300 child of Ada.Containers. It provides functional indefinite unbounded
4301 maps which can be used as high level models for specification
4303 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4304 child of Ada.Containers. It provides functional indefinite unbounded
4305 sets which can be used as high level models for specification
4307 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4308 child of Ada.Containers. It provides functional indefinite unbounded
4309 vectors which can be used as high level models for specification
4311 * Makefile.rtl: Add new packages.
4312 * impunit.adb: Add new packages.
4314 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4316 * sem_ch4.adb: Minor reformatting.
4318 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4320 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4321 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4322 point type actual that has user-defined arithmetic primitives,
4323 when there is a previous actual for a formal package that defines
4324 a fixed-point type with the parent user-defined operator.
4326 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4328 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4329 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4330 the component type allows range checks.
4332 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4334 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4335 corresponding declaration, because formal derived types are
4336 rewritten as private extensions.
4338 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4340 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4341 dimensions of operands if node has been analyzed already, because
4342 previous analysis and dimension checking will have removed the
4343 dimension information from the operands.
4345 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4347 * debug.adb: Document the use of switch -gnatd.s.
4348 * einfo.ads Update the documentation on attribute
4349 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4350 the uses of these attributes from certain entities.

4352 which determines whether the block should continue to manage
4353 the secondary stack.

4401 * exp_ch4.adb (Expand_N_Case_Expression): Emit error message when
4402 generating C code on complex case expressions.
4404 2017-04-25 Arnaud Charlet <charlet@adacore.com>
4406 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
4407 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4408 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4409 Ada_2012 instead of Ada_2005 to be compatible with the above
4411 * bindgen.adb: Silence new warning on pragma Ada_95.
4413 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4415 * checks.adb (Generate_Range_Check): Revert part of previous change.

4421 parameter association in a procedure call.
4423 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
4425 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4426 Fix spelling mistakes.
4428 2017-04-25 Bob Duff <duff@adacore.com>
4430 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4431 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4432 for source buffers. Fix misc obscure bugs.
4433 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4434 checking, for source buffers. Modify representation clause for
4435 Source_File_Record as appropriate. Move Source_File_Index_Table
4436 from spec to body, because it is not used outside the body.
4437 Move Set_Source_File_Index_Table into the private part, because
4438 it is used only in the body and in children. Use trickery to
4439 modify the dope in the generic instantiation case. It's ugly,
4440 but not as ugly as the previous method. Fix documentation.
4441 Remove obsolete code.
4442 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
4443 indexing in source buffers.

4457 expander is not active or when index/range checks are suppressed
4459 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4460 Remove variants that include a Supress parameter. These routines
4461 are never used, and were introduced before the current scope-based
4462 check suppression method.
4464 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>
4466 * prj-part.adb, cstreams.c, osint.adb, osint.ads: Remove VMS specific

4479 (Known_Null): Moved to Sem_Util.
4480 * sem_util.adb Add new enumeration type Null_Status_Kind.
4481 (Known_Non_Null): Moved from Exp_Util. Most of the logic in
4482 this routine is now carried out by Null_Status.
4483 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
4484 is now carried out by Null_Status.
4485 (Null_Status): New routine.

4491 * sem_ch6.adb (Analyze_Expression_Function): Do not report an
4492 error on the return type of an expression function that is a
4493 completion, if the type is derived from a generic formal type.
4495 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4497 * sem_dim.adb (Dimensions_Of_Operand): The dimensions of a type
4498 conversion are those of the target type.

4512 errout.adb, sinput.adb, sinput.ads, cstand.adb, scn.adb,
4513 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4514 the Internal_Source buffer. This removes the incorrect call to "="
4515 the customer noticed.
4516 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4517 eventually need to eliminate them altogether. Or else get rid
4518 of zero-origin addressing.
4520 2017-04-25 Claire Dross <dross@adacore.com>
4522 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New

5086 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5087 dereference is introduced for the object, and the object is
5088 overloaded, do not check whether it is aliased, because it may
5089 include an implicit dereference.
5090 * sem_type.adb (Disambiguate): If two interpretations are access
5091 attribute types with the same designated type keep either of
5092 them and do not report an ambiguity. A true ambiguity will be
5095 2017-04-25 Bob Duff <duff@adacore.com>
5097 * a-numeri.ads: Change the encoding of Greek letter Pi from
5098 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5099 to indicate the encoding. We considered using a byte order mark
5100 (BOM), but that causes various trouble (misc software eats the
5101 BOM, if you have a patch with a BOM, then it's not at the start
5102 of the patch, so it's not a BOM, the BOM affects with-ing files,

5146 enforce legality rule on classwide preconditions inherited from
5147 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5148 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5149 subprogram need not be dispatching if it appears in a precondition
5150 for an abstract or null subprogram.
5152 2017-04-25 Gary Dismukes <dismukes@adacore.com>

5163 have a length which is a power of 2.
5164 (Is_Predefined_File_Name): Likewise. Adjust comment.
5166 2017-04-25 Bob Duff <duff@adacore.com>
5168 * exp_aggr.adb (Component_Count): Protect the
5169 arithmetic from attempting to convert a value >= 2**31 to Int,
5170 which would otherwise raise Constraint_Error.
5172 2017-04-25 Bob Duff <duff@adacore.com>
5174 * opt.ads (Locking_Policy): Fix incorrect documentation. The

5198 Save and restore the value of global flag
5199 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

5201 the corresponding spec or the body must ignore all SPARK_Mode
5202 pragmas found within.
5203 (Analyze_Subprogram_Declaration): Mark
5204 the spec when it needs to ignore all SPARK_Mode pragmas found
5205 within to allow the body to infer this property in case it is
5206 instantiated or inlined later.
5207 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5208 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5209 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5210 when the corresponding spec also ignored all SPARK_Mode pragmas
5212 (Analyze_Package_Declaration): Mark the spec when
5213 it needs to ignore all SPARK_Mode pragmas found within to allow

5217 Save and restore the value of flag
5218 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5219 formal spec when it needs to ignore all SPARK_Mode

5221 property in case it is instantiated or inlined later.
5222 (Analyze_Package_Instantiation): Save and restore the value
5223 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark

5243 Ignore_Pragma_SPARK_Mode.
5244 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5245 all SPARK_Mode pragmas defined within yields mode "off".
5247 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5249 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

5266 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5268 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5269 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5270 variable and set it to True whenever the main hash table is
5271 populated. Short- circuit the Assoc function if it is false
5272 and add associated guards.
5274 2017-04-25 Olivier Hainque <hainque@adacore.com>
5276 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5277 specs without elaboration code that have an elaboration counter
5278 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5279 * sem_ch10.adb (Analyze_Compilation_Unit):
5280 Set_Elaboration_Entity_Required when requested to preserve
5281 control flow, to ensure the unit elaboration is materialized at
5282 bind time, resulting in the inclusion of the unit object file
5283 in the executable closure at link time.
5285 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5287 * exp_dbug.adb: In Debug_Renaming_Declaration,
5288 when dealing with indexed component, accept to produce a renaming
5289 symbol when the index is an IN parameter or when it is a name
5290 defined in an outer scope.
5292 2017-04-25 Yannick Moy <moy@adacore.com>
5294 * errout.adb (Error_Msg): Adapt continuation
5295 message in instantiations and inlined bodies for info messages.
5297 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5299 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5300 Use direct 4-character slice comparisons.
5302 pragma Inline. (Has_Suffix): Delete.
5303 (Is_Internal_File_Name):
5304 Test Is_Predefined_File_Name first.
5305 (Is_Predefined_File_Name):

5309 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5311 * checks.adb (Insert_Valid_Check): Code cleanup.
5312 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5313 (Expand_Actuals): Generate proper copy-back for a validation
5314 variable when it acts as the argument of a type conversion.
5315 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5316 predicate to operate on type qualifications.
5318 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5320 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5323 2017-04-25 Bob Duff <duff@adacore.com>
5325 * sem_prag.adb (No_Return): Give an error if the pragma applies
5326 to a body. Specialize the error for the specless body case,
5327 as is done for (e.g.) pragma Convention.
5328 * debug.adb: Add switch -gnatd.J to disable the above legality
5329 checks. This is mainly for use in our test suite, to avoid
5330 rewriting a lot of illegal (but working) code. It might also
5331 be useful to customers. Under this switch, if a pragma No_Return
5332 applies to a body, and the procedure raises an exception (as it
5333 should), the pragma has no effect. If the procedure does return,
5334 execution is erroneous.
5336 2017-04-25 Bob Duff <duff@adacore.com>
5338 * exp_ch6.adb (Expand_Actuals): This is the
5339 root of the problem. It took N as an 'in out' parameter, and in
5340 some cases, rewrote N, but then set N to Original_Node(N). So
5341 the node returned in N had no Parent. The caller continued
5342 processing of this orphaned node. In some cases that caused a
5343 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5344 and trips over the Empty Parent). The solution is to make N an
5345 'in' parameter. Instead of rewriting it, return the list of
5346 post-call actions, so the caller can do the rewriting later,
5347 after N has been fully processed.
5348 (Expand_Call_Helper): Move most of Expand_Call here. It has
5349 too many premature 'return' statements, and we want to do the
5350 rewriting on return.
5351 (Insert_Post_Call_Actions): New procedure to insert the post-call
5352 actions in the appropriate place. In the problematic case,
5353 that involves rewriting N as an Expression_With_Actions.
5354 (Expand_Call): Call the new procedures Expand_Call_Helper and
5355 Insert_Post_Call_Actions.
5357 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5359 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5360 properly type derived from generic formal types, to handle
5361 properly modified version of ACATS 4.1B B611017.
5363 2017-04-25 Javier Miranda <miranda@adacore.com>
5365 * exp_unst.adb (Subp_Index): Adding missing
5366 support for renamings and functions that return a constrained
5367 array type (i.e. functions for which the frontend built a
5368 procedure with an extra out parameter).
5370 2017-04-25 Pascal Obry <obry@adacore.com>
5372 * s-string.adb: Minor code clean-up.
5374 2017-04-25 Bob Duff <duff@adacore.com>

5381 2017-04-25 Bob Duff <duff@adacore.com>
5383 * prep.adb (Preprocess): Remove incorrect
5384 Assert. Current character can be ASCII.CR.
5386 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5388 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5389 convention Stdcall, which has a number of exceptions. Convention
5390 is legal on a component declaration whose type is an anonymous
5391 access to subprogram.
5393 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5395 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5396 (Try_One_Prefix_Interpretation): Use the base type when dealing
5397 with a subtype created for purposes of constraining a private
5398 type with discriminants.
5400 2017-04-25 Javier Miranda <miranda@adacore.com>

5406 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5407 to enable/disable this warning.
5408 (WA_Warnings): Set warning on late dispatching primitives.
5409 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5410 that its parent type has a private extension.
5411 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5413 * usage.adb: Document -gnatw.j and -gnatw.J.
5415 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5420 2017-04-25 Bob Duff <duff@adacore.com>
5422 * binde.adb (Validate): Do not pass dynamic strings
5423 to pragma Assert, because older compilers do not support that.
5425 2017-04-25 Bob Duff <duff@adacore.com>
5427 * s-fileio.adb (Close): When a temp file is
5428 closed, delete it and clean up its Temp_File_Record immediately,
5429 rather than waiting until later.
5430 (Temp_File_Record): Add File
5431 component, so Close can know which Temp_File_Record corresponds
5432 to the file being closed.
5433 (Delete): Don't delete temp files,
5434 because they are deleted by Close.
5435 (Open): Set the File component
5436 of Temp_File_Record. This requires moving the creation of the
5437 Temp_File_Record to the end, after the AFCB has been created.
5439 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5441 * checks.adb (Insert_Valid_Check): Do not generate
5442 a validity check when inside a generic.

5463 2017-04-25 Yannick Moy <moy@adacore.com>
5465 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5466 conversions from float to integer in GNATprove mode.
5467 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5468 to call Apply_Type_Conversion_Checks, so that range checks
5469 are properly positioned when needed on conversions, including
5470 when converting from float to integer. (Determine_Range): In
5471 GNATprove mode, take into account the possibility of conversion
5472 from float to integer.
5473 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5474 check on conversions from fixed-point to integer, not anymore
5475 on conversions from floating-point to integer, when in GNATprove
5478 2017-04-25 Yannick Moy <moy@adacore.com>
5480 * checks.adb (Determine_Range_R): Special case type conversions
5481 from integer to float in order to get bounds in that case too.
5482 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5483 mode, for computations involved in interval checking.

5498 variables to avoid extra reads and copies of the prefix.
5499 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5500 variables in order to reflect any changes done in the variable
5501 back into the original object.
5502 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5503 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5511 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5513 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5514 Analyze_Pre_Post_Condition, to implement the legality checks
5515 mandated by AI12-0131: Pre'Class shall not be specified for an
5516 overriding primitive subprogram of a tagged type T unless the
5517 Pre'Class aspect is specified for the corresponding primitive
5518 subprogram of some ancestor of T.
5520 2017-04-25 Bob Duff <duff@adacore.com>
5522 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5523 is redundant, set its Used_Operations to empty. This is only
5524 necessary for use clauses that appear in the parent of a generic
5525 child unit, because those use clauses get reanalyzed when we
5526 instantiate the generic, and we don't want the Used_Operations
5527 carried over from the original context (where it was probably
5530 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5532 * exp_ch6.adb: Minor reformatting.

5545 * sem_ch8.adb (Find_Type): For an attribute reference
5546 'Class, if prefix type is synchronized and previous errors
5547 have suppressed the creation of the corresponding record type,
5548 create a spurious class-wide for the synchonized type itself,
5549 to catch other misuses of the attribute

5558 tag checks for the result of call to an instance of
5559 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5560 descendant of" check and the accessibility check).

5572 the operation out-of-line if the concatenation is present within
5573 the expression of the declaration of a library-level object and
5574 not only if it is the expression of the declaration.
5576 2017-04-25 Bob Duff <duff@adacore.com>
5578 * freeze.adb (Freeze_Object_Declaration): Do
5579 not Remove_Side_Effects if there is a pragma Linker_Section,
5580 because in that case we want static initialization in the
5581 appropriate section.
5583 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5585 * exp_dbug.adb: Minor rewording and reformatting.
5587 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5589 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5590 handle the proposed changes to rules concerning potentially
5591 unevaluated expressions, to include selected components that
5592 do not depend on discriminants, and indexed components with
5594 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5595 predicate in quantified expression, and fix bugs in the handling
5596 of case expressions and membership test.

5614 renaming entity for debug information, mark the entity as needing debug
5615 info if it comes from sources.
5617 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5619 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

5625 * exp_dbug.adb: In Debug_Renaming_Declaration,
5626 skip slices that are made redundant by an indexed component

5638 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5639 internal calls that appear in preconditions of protected
5640 operations, in default values for same, and in contract guards
5641 for contract cases in SPARK.
5643 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5645 * a-numaux.ads: Fix description of a-numaux-darwin

5652 * a-numaux-x86.ads: Fix package description.
5653 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5654 (Reduce): Adjust and complete description. Call Is_Nan instead of
5655 testing manually. Use an integer temporary to hold rounded value.
5656 * a-numaux-darwin.adb (Reduce): Likewise.
5657 (Is_Nan): New function.
5659 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5661 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5662 on analysis of prefix whose type is a current instance of a
5663 synchronized type, but where the prefix itself is an entity that
5666 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5668 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5669 the identity of callable entities therein, because they have been
5670 properly resolved, and prefixed calls may have been rewritten
5673 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5675 * exp_ch3.adb (Build_Init_Statements): Convert
5676 the expression of the pragma/aspect Secondary_Stack_Size to
5677 internal type System.Parameters.Size_Type before assigning
5678 it to the Secondary_Stack_Size component of the task type's
5679 corresponding record.

5683 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
5684 (etc) optimizations when the type is modular and the offsets
5687 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5689 * s-osinte-freebsd.ads: Minor comment tweaks
5691 2017-04-25 Javier Miranda <miranda@adacore.com>
5693 * urealp.adb (UR_Write): Reverse previous patch
5694 adding documentation on why we generate multiplications instead
5695 of divisions (needed to avoid expressions whose computation with
5696 large numbers may cause division by 0).
5698 2017-04-25 Bob Duff <duff@adacore.com>
5700 * erroutc.adb (Set_Specific_Warning_Off,
5701 Set_Warnings_Mode_Off): Use the correct source file for
5702 Stop. Was using Current_Source_File, which is only valid during
5703 parsing. Current_Source_File will have a leftover value from
5704 whatever file happened to be parsed last, because of a with_clause
5707 2017-04-25 Bob Duff <duff@adacore.com>
5709 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5710 to In_Predefined_Unit, but including GNAT units.
5711 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5712 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5713 because Should_Ignore_Pragma was not working reliably outside
5714 the parser, because Current_Source_File is not valid.
5715 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5716 * par-prag.adb: Call Should_Ignore_Pragma_Par.
5718 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

5753 Build_Invariant_Procedure_Body.
5754 (Build_Invariant_Procedure_Body):
5755 Remove refactored calls and integrated code from
5756 Add_Parent_Invariants and Add_Interface_Invariants.
5758 2017-04-25 Johannes Kanig <kanig@adacore.com>
5760 * errout.adb (Output_Messages): Adjust computation of total
5762 * erroutc.adb (Error_Msg): In statistics counts, deal
5763 correctly with informational messages that are not warnings.
5764 * errutil.adb (Finalize): adjust computation of total errors.
5766 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

5775 2017-04-25 Justin Squirek <squirek@adacore.com>
5777 * sem_ch3.adb (Analyze_Declarations): Minor
5778 correction to comments, move out large conditional and scope
5779 traversal into a predicate.
5780 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5783 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5785 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5786 of prefix whose type is a current instance of a synchronized
5787 type. If the prefix is an object this is an external call (or
5788 requeue) that can only access public operations of the object. The
5789 previous predicate was too restrictive, and did not allow public
5790 protected operations, only task entries.
5792 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5794 * sem_ch5.adb, fname.adb: Minor reformatting.
5796 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5798 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5799 * einfo.ads Update the placement of
5800 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5802 (Is_Anonymous_Access_Type): New routine.
5803 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5804 master for an access type subject to pragma No_Heap_Finalization.
5805 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5806 allocated or deallocated does not finalization actions if the
5807 associated access type is subject to pragma No_Heap_Finalization.
5808 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5809 * par-prag.adb Pragma No_Heap_Finalization does not need special
5810 processing from the parser.
5811 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5812 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5813 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5814 No_Heap_Finalization.
5815 (Analyze_Pragma): Add processing for
5816 pragma No_Heap_Finalization. Update various error messages to
5817 use Duplication_Error.
5818 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5819 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5820 and corresponding pragma id.
5822 2017-04-25 Bob Duff <duff@adacore.com>
5824 * freeze.adb (Freeze_Record_Type): Use the
5825 underlying type of the component type to determine whether it's
5826 elementary. For representation clause purposes, a private type
5827 should behave the same as its full type.
5828 * fname.ads, fname.adb (Is_Predefined_File_Name):
5829 Make sure things like "system.ali" are recognized as predefined.
5831 2017-04-25 Javier Miranda <miranda@adacore.com>
5833 * debug.adb: Update documentation of -gnatd.6.

5837 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5838 element iterator when the name is an overloaded function call,
5839 one of whose interpretations yields an array.
5841 2017-04-25 Bob Duff <duff@adacore.com>
5843 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5844 Is_Internal_Unit_Name): New functions for operating on unit
5845 names, as opposed to file names. There's some duplicated code
5846 with fname.adb, which is unfortunate, but it seems like we don't
5847 want to add dependencies here.
5848 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5849 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5850 is not a file name at all.
5851 * fname.ads, fname.adb: Document the fact that
5852 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5853 for ALI files, and fix the code so it works properly for ALI
5854 files. E.g. these should return True for "system.ali".
5856 2017-04-25 Justin Squirek <squirek@adacore.com>
5858 * exp_util.adb (Add_Invariant): Removed,
5859 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5860 and Add_Own_Invariant. (Add_Invariant_Check): Used
5861 for adding runtime checks from any kind of invariant.
5862 (Add_Inherited_Invariant): Generates invariant checks for
5863 class-wide invariants (Add_Interface_Invariants): Removed, code
5864 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

5866 Removed, code moved to Build_Invariant_Procedure_Body
5867 (Build_Invariant_Procedure_Body): Add refactored calls
5868 and integrated code from Add_Parent_Invariants and
5869 Add_Interface_Invariants.
5870 (Process_Type): Removed, the
5871 relavant code was inlined into both Add_Own_Invariant and
5872 Add_Inherited_Invariant.
5874 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5876 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5893 and Build_Invariant_Procedure_Declaration.
5894 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5895 and Build_Invariant_Procedure_Declaration from exp_ch7
5896 and break-out Is_Untagged_Private_Derivation from
5897 Build_Invariant_Procedure_Body.
5898 (Replace_Type_References):
5899 Append an extra parameter to allow for dispatching replacements
5900 and add the corrasponding logic.
5901 (Type_Invariant): Remove
5902 Replace_Typ_Refs and replace its references with calls to
5903 Replace_Type_References.
5904 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5906 2017-04-25 Bob Duff <duff@adacore.com>
5908 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5909 that returns True when appropriate.
5910 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5911 when compiling predefined files.
5912 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5913 "gnat.adc" should not be considered a predefined file name.
5914 That required (or at least encouraged) a lot of cleanup of global
5915 variable usage. We shouldn't be communicating information via
5916 the global name buffer.
5917 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5918 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5923 * osint.adb (Find_File): Handle properly a request for a
5924 configuration file whose name is a directory.

5938 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5939 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5940 Add String_To_Name with no side effects.
5942 2017-04-25 Justin Squirek <squirek@adacore.com>
5944 * sem_ch3.adb (Analyze_Declarations): Add
5945 additional condition for edge case.

5949 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5950 reserved words inside pragmas. This is necessary to allow the
5951 pragma name Interface to be used in pragma Ignore_Pragma.

5954 2017-04-25 Javier Miranda <miranda@adacore.com>
5956 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

5977 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
5978 the first pass over an assignment statement with target names,
5979 to prevent the generation of subtypes (such as discriminated
5980 record components)that may carry the target name outside of the
5981 tree for the assignment. The subtypes will be generated when
5982 the assignment is reanalyzed in full.
5983 (Analyze_Target_Name): Handle properly class-wide types.

6015 properties of the private type to the full view in case the full
6016 view derives from a parent type and inherits a DIC pragma.
6017 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6018 DIC pragma is placed at the top of a declarative region.
6020 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6022 * a-tasatt.adb: Complete previous change and use an unsigned
6023 int to avoid overflow checks.
6025 2017-04-25 Ed Schonberg <schonberg@adacore.com>

6028 the error message when the attribute reference is an actual in
6029 a call to a subprogram inherited from a generic formal type with
6030 unknown discriminants, which makes the subprogram and its formal
6031 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6033 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6035 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6038 2017-04-25 Bob Duff <duff@adacore.com>
6040 * sem_attr.adb (Type_Key): Add code in the
6041 recursive Compute_Type_Key to protect against fetching the source
6042 code for Standard, in case a component of the type is declared
6043 in Standard. There was already code to do this for the original
6044 type, but not for its components.
6046 2017-04-25 Javier Miranda <miranda@adacore.com>
6048 * exp_ch3.adb (Build_Initialization_Call): Handle
6049 subtypes of private types when searching for the underlying full
6050 view of a private type.

6064 or inlining purposes, the body of U1 needs to be compiled as well.
6065 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
6066 context is a package declaration.
6067 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
6068 Analyze_Generic_Package_Declaration): ditto.

6742 (Check_Dependency_Clause): Properly detect a match between two
6743 'Result attributes. Update the various post-match cases to use

6807 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6808 an object declaration for an array type with a modular index type
6809 with the size of Long_Long_Integer. Special processing is needed
6810 in this case to compute reliably the size of the object, and
6811 eventually to raise Storage_Error, when wrap-around arithmetic
6812 might compute a meangingless size for the object.
6814 2017-01-23 Justin Squirek <squirek@adacore.com>

6821 * sem_res.adb (Resolve_Call): In the part of the code where
6822 it is deciding whether to turn the call into an indexed
6823 component, avoid doing so if the call is to an instance of
6824 Unchecked_Conversion. Otherwise, the compiler turns it into an
6825 indexed component, and resolution of that turns it back into a
6826 function call, and so on, resulting in infinite recursion.
6827 * sem_util.adb (Needs_One_Actual): If the first formal has a
6828 default, then return False.

6875 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6876 must be treated as delayed aspect even if the expression is

6930 returns a limited view of a type and at the point of the call the
6931 function is not declared in the extended main unit then replace
6932 it with the non-limited view, which must be available. If the
6933 called function is in the extended main unit then no action is
6934 needed since the back-end handles this case.

6948 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6949 base type differs from that of the completion and the private
6950 subtype is an itype (created for a constraint on an access

7159 so that the procedure can be used to check the array type
7161 (Freeze_Record_Type): In GNATprove mode, do
7162 not add the component invariants to the record type invariant
7163 procedure so that the procedure can be used to check the record

7186 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
7187 type, ie. a type whose component is a character type, and the
7188 aggregate is positional, do not convert into a string literal
7189 if the index type is not an integer type, because the original
7190 type may be required in an enclosing operation.
7192 2017-01-19 Bob Duff <duff@adacore.com>
7194 * binde.adb, debug.adb: Enable new elaboration order algorithm
7195 by default. -dp switch reverts to the old algorithm.

7240 * exp_ch6.adb (Expand_Call): Remove side effects on
7241 actuals that are allocators with qualified expression since the
7242 initialization of the object is performed by means of individual
7243 statements (and hence it must be done before the call).
7245 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7247 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7248 (Build_Derived_Enumeration_Type): If the derived type inherits a
7249 dynamic predicate from its parent, the bounds of the type must
7250 freeze because an explicit constraint is constructed for the
7251 type and the corresponding range is elaborated now.

7302 wrong since we just issued a warning message.
7303 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
7304 these variables to be of subtype Nat instead of Int, because
7305 they should never be negative.

7332 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
7334 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
7336 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7338 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7339 selected component has a prefix that might be interpreted
7340 as a parameterless function call, but none of the candidate
7341 interpretations is parameterless, and there is a hidden homonym
7342 of the prefix that is a package.
7343 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7344 interpreted as a parameterless function call and its analysis
7345 fails, do not call Analyze_Selected_Component.

7349 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7351 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7352 calls to a newly-defined Scalar_Range_Of_Right_View function.
7354 2017-01-19 Arnaud Charlet <charlet@adacore.com>

7359 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7360 from repeated code of Traverse_Compilation_Unit.
7361 (Traverse_Declaration_Or_Statement): fixed detection of
7362 generic subprograms and packages; also, iteration over case
7363 statement alternatives rewritten to avoid testing if the first
7364 alternative is present (since it must be present due to Ada
7365 syntax restrictions).
7367 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7369 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
7370 returning by reference not just for subprogram body stubs,

7380 identifier nodes that do not come from source, to handle properly
7381 dimensionality check within an inlined body which inclddes both
7382 original operands and rewritten operands. This removes spurious
7383 dimensionality errors in the presence of front-end inlining,
7384 as well as in SPARK mode.
7386 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7425 * scil_ll.adb: Minor style fix in comment.
7426 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
7427 even if entity is already set, because the node may be renalyzed
7428 after inlining transformations.

7457 * sem_ch6.adb (Cloned_Expression): New subprogram.
7458 (Freeze_Expr_Types): Complete previous patch since the expression
7459 of an expression-function may have iterators and loops with
7460 defining identifiers which, as part of the preanalysis of the
7461 expression, may be left decorated with itypes that will not be
7462 available in the tree passed to the backend.
7464 2017-01-13 Ed Schonberg <schonberg@adacore.com>

7482 Ensure that the input body is a subprogram body before trying to
7483 determine whether it denoted an expression function. Note that
7484 subprogram body stubs cannot denote expression functions.

7502 2017-01-13 Bob Duff <duff@adacore.com>
7504 * binde.adb (Elab_New): New elaboration order algorithm
7505 that is expected to cause fewer ABE issues. This is a work in
7506 progress. The new algorithm is currently disabled, and can be
7507 enable by the -dp switch, or by modifying the Do_Old and Do_New
7508 etc. flags and rebuilding. Experimental code is included to
7509 compare the results of the old and new algorithms.
7510 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7511 can have multiple of these tables, so the old and new algorithms
7513 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7514 parameter of type array. This avoids the global variable, and
7515 allows bounds checking (which is normally defeated by the tables
7516 packages). It also ensures that the Elab_Order is read-only
7518 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7519 subprograms that need it, as above.
7520 * debug.adb: Document new -dp switch. Modify doc of old -do
7522 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7523 and Bindgen. Move writing of closure (-R and -Ra switches)

7526 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7528 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7529 function is a completion, all entities referenced in the
7530 expression are frozen. As a consequence, a reference to an
7531 uncompleted private type from an enclosing scope is illegal.
7533 2017-01-13 Javier Miranda <miranda@adacore.com>
7535 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7536 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7537 expression function declaration that is a completion, its
7538 expression causes freezing (AI12-0103).
7540 2017-01-13 Vadim Godunko <godunko@adacore.com>
7542 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7588 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7590 * sem_util.ads, sem_util.adb (Choice_List): Move function here
7591 from sem_aggr.adb, for use elsewhere.
7592 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
7593 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
7594 Iterated_Component_Present.

7596 Iterated_Component_Associations.
7597 (Gen_Loop): Generate proper loop for an
7598 Iterated_Component_Association: loop variable has the identifier
7599 of the original association. Generate a loop even for a single
7600 component choice, in order to make loop parameter visible in
7602 (Flatten): An Iterated_Component_Association is not static.
7604 2017-01-13 Yannick Moy <moy@adacore.com>
7606 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7607 float exponentiation for statically known small negative values
7608 is the reciprocal of the exponentiation for the opposite value
7610 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):

7621 expression in delay statement as OK for volatile context.
7623 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7625 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7626 mode a choice that is a subtype with a static predicate is
7627 replaced by the values it covers. This transformation must not
7628 be performed in ASIS mode, to preserve the source for analysis.
7630 2017-01-13 Justin Squirek <squirek@adacore.com>
7632 * nlists.ads: Correct minor typo.
7634 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7644 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7645 and resolve the discrete choices and the expression of the
7647 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7648 Loop_Actions and Box_Present are attributes of
7649 N_Iterated_Component_Association nodes. Box_Present is always
7651 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7652 has a Discrete_Choices list, as specified in the RM. A
7653 Component_Association for aggregate uses instead a Choices list.
7654 We have to live with this small inconsistency because the new
7655 construct also has a defining identifier, and there is no way
7656 to merge the two node structures.
7658 2017-01-13 Yannick Moy <moy@adacore.com>
7660 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
7661 list of pragmas to remove. Remove pragmas from the list of

7665 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7667 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
7668 Analyze_Declarations, to analyze and resolve the expressions of
7669 aspect specifications in the current declarative list, so that
7670 the expressions have proper entity and type info. This is needed
7671 for ASIS when there is no subsequent expansion to generate this
7672 semantic information.
7673 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7674 original expression, to suppress cascaded errors when expression
7675 has been constant-folded.
7676 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7677 ASIS mode, because there is no subsequent expansion to decorate
7680 2017-01-13 Yannick Moy <moy@adacore.com>

7683 New function to detect when a call may be inlined or not in
7685 (Expand_Inlined_Call): Ensure that a temporary
7686 is always created in the cases where a type conversion may be
7687 needed on an input parameter in GNATprove mode, so that GNATprove
7688 sees the check to perform.
7689 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7690 when not applicable due to actual requiring type conversion
7691 with possible check but no temporary value can be copied for
7692 GNATprove to see the check.
