310 2017-09-08 Yannick Moy <moy@adacore.com>
312 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
313 return the entity associated with the call.
314 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
315 Replace the internal Get_Function_Id with the new
316 Sem_Aux.Get_Called_Entity.
317 (Iterate_Call_Parameters): New
318 procedure to iterate on formals and actuals at the same time.
319 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
320 Set SPARK_Mode from spec when set, for analysis
321 of instance. Restore after analysis of instance.
322 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
323 set, for analysis of body instance. Restored automatically at
324 the end of the subprogram.
325 * gnat1drv.adb (Adjust_Global_Switches): Set
326 Check_Validity_Of_Parameters to False in GNATprove mode.
327 * opt.ads (Check_Validity_Of_Parameters): Document switch to
330 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
332 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
333 (New_Copy_Tree): ...there. Reset the hash tables only if they
334 were used in the previous invocation.
335 * s-htable.adb: Fix typo.
337 2017-09-08 Bob Duff <duff@adacore.com>
339 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
341 2017-09-08 Arnaud Charlet <charlet@adacore.com>

345 2017-09-08 Bob Duff <duff@adacore.com>
347 * sprint.adb (Write_Corresponding_Source): Ignore if there is
348 no current source file.
349 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
350 Print something helpful in case N is invalid.
351 * sprint.ads: Minor comment fix.
353 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
355 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
358 2017-09-08 Bob Duff <duff@adacore.com>
360 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
361 Ada_2020, along the same lines as the other Ada version pragmas.
363 2017-09-08 Gary Dismukes <dismukes@adacore.com>
365 * sem_ch12.adb: Minor typo fixes and reformatting.
367 2017-09-08 Yannick Moy <moy@adacore.com>
369 * sem_aggr.adb (Resolve_Record_Aggregate):
370 Rewrite bounds of aggregate subexpressions which may depend on
371 discriminants of the enclosing aggregate.
373 2017-09-08 Yannick Moy <moy@adacore.com>
375 * sem_ch5.adb: Prevent assertion failure on illegal code.
377 2017-09-08 Yannick Moy <moy@adacore.com>
379 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
380 calling Renamed_Entity on an entity which cannot be a renaming.
382 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
384 * exp_aggr.adb: Add with & use clause for Urealp.
385 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
386 elementary types instead of just discrete types.
387 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
388 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
389 Be prepared for the FP zero value in the memset case. Add small
392 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
394 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
397 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
399 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
400 of New_Copy because the latter leaves the syntactic structure of
401 the tree inconsistent (a child is accessible through two parents)
402 and prevents proper replication of itypes by subsequent calls
404 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
405 New_Copy because the latter leaves the syntactic structure of the
406 tree inconsistent (a child is accessible through two parents)
407 and prevents proper replication of itypes by subsequent calls
409 * sem_util.adb (In_Subtree): New routine.
410 (New_Copy_Tree): Reimplemented.

414 2017-09-08 Ed Schonberg <schonberg@adacore.com>
416 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
417 for aspect Default_Value is a static scalar value, but it does
418 not freeze the type. Yhis allows for subsequent representation
419 clauses for the type.
421 2017-09-08 Javier Miranda <miranda@adacore.com>
423 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
424 not add entries into the undefined reference table when we are
425 compiling with errors ignored.
427 2017-09-08 Ed Schonberg <schonberg@adacore.com>
429 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
430 check if the instance is within an enclosing instance body. The
431 formal package was legal in the enclosing generic, and is
432 legal in the enclosing instantiation. This optimisation may be
433 applicable elsewhere, and it also removes spurious errors that
434 may arise with on-the-fly processing of instantiations that
435 contain Inline_Always subprograms.
437 2017-09-08 Vincent Celier <celier@adacore.com>
439 * gnatcmd.adb: Disregard empty argument of GNAT driver.
441 2017-09-08 Justin Squirek <squirek@adacore.com>
443 * checks.adb (Insert_Valid_Check): Manually decorate
444 the generated temporary for range valdity checks.
446 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
448 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
450 2017-09-08 Justin Squirek <squirek@adacore.com>
452 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
453 case to handle underscore flags.
454 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
455 new procedure to handle underscores.
457 2017-09-08 Javier Miranda <miranda@adacore.com>
459 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
460 divisions with fixed point results to avoid generating twice
461 the runtime check on divide by zero.
462 * checks.adb (Apply_Divide_Checks): Ensure that operands are
463 not evaluated twice (once for their runtime checks and once for
464 their regular computation).
466 2017-09-08 Yannick Moy <moy@adacore.com>
468 * sem_prag.adb (Analyze_Part_Of): Add missing
469 return statements after issuing errors. Add detection of
470 out-of-order item and single concurrent type.

571 s-objrea.adb, s-tsmona-linux.adb, s-tsmona-mingw.adb: New.
572 * gcc-interface/Makefile.in: Enable s-trasym-dwarf.adb on x86*linux.
574 2017-09-08 Bob Duff <duff@adacore.com>
576 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
577 New routine to read the Tag robustly.
578 * exp_attr.adb (Input): Change the expansion of 'Input,
579 in the class-wide case, to call String_Input_Tag instead of
582 2017-09-08 Arnaud Charlet <charlet@adacore.com>
584 * s-rident.ads (Restriction_Id): reorder enum
585 literals, so that Pure_Barriers is no longer in range of the
586 Cunit_Boolean_Restrictions subtype.
588 2017-09-08 Nicolas Roche <roche@adacore.com>
590 * a-taster.ads, a-taster.adb: Move to libgnarl
591 * gcc-interface/Makefile.in: Remove obsolete targets. Code cleanups.
592 Add support for files in libgnarl.

597 accessibility check to an interface conversion, whose purpose
598 is to perform a pointer adjustment in a dispatching call.
599 * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
600 when the actual is a construct that involves a dereference of an
601 expression that includes a formal of the enclosing subprogram,
602 In such cases, the accessibility level of the actual is that of
603 the corresponding formal, which is passed in as an additional
604 actual in the outer call.
606 2017-09-08 Bob Duff <duff@adacore.com>
608 * exp_intr.adb (Add_Source_Info): Do not decode
609 file names; they were not encoded in the first place.
611 2017-09-08 Bob Duff <duff@adacore.com>
613 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
614 exceptions instead of crashes. Check for absurdly long strings
615 and empty strings. Empty strings cause trouble because they can
616 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
617 be empty, which causes an array index out of bounds.
618 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
621 2017-09-08 Arnaud Charlet <charlet@adacore.com>
623 * sem_util.adb (Is_CCT_Instance): allow use in

643 not skip a loop coming from source which is rewritten into a loop.
645 2017-09-08 Ed Schonberg <schonberg@adacore.com>
647 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
648 wrapper has convention Ada, to prevent spurious warnings on
649 unconstrained array parameters.

674 generating warning message.
676 2017-09-08 Ed Schonberg <schonberg@adacore.com>
678 * par-ch4.adb (P_Iterated_Component_Association): Place construct
679 under -gnat2020 flag, given that it is a future feature of
681 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
682 defining identifier as referenced to prevent spurious warnings:
683 corresponding loop is expanded into one or more loops whose
684 variable has the same name, and the expression uses those names
685 and not the original one.
687 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

709 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
711 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
712 Correction of the return type from access type to option type.
713 (Simple_HTable): Moving the Instance_Data to ads file.
715 2017-09-08 Yannick Moy <moy@adacore.com>

757 subprogram containing code that was previously inside
758 Make_Build_In_Place_Call_In_Object_Declaration since it is also
759 required for one of the new subprograms.
761 Invoke Make_Build_In_Place_Iface_Call_In_Anonymous_Context
762 (Expand_N_Extended_Return_Statement): Extend the
763 cases covered by an assertion on expected BIP object

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

776 * exp_ch3.adb (Expand_N_Object_Declaration): Invoke the new
777 subprogram Make_Build_In_Place_Iface_Call_In_Object_Declaration.
778 * exp_attr.adb (Expand_N_Attribute_Reference): Invoke the new
779 subprogram Make_Build_In_Place_Iface_Call_In_Anonymous_Context.

794 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
795 access to interface types. Remove also the accessibility check.
797 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
799 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
800 all the types that are referenced by the expression.
801 (Analyze_Expression_Function): Call Freeze_Expr_Types for
802 a completion instead of manually freezing the type of the
804 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
806 2017-09-08 Ed Schonberg <schonberg@adacore.com>
808 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
809 New procedure, auxiliary to Expand_Pragma_Check, to handle
810 references to the discriminants of a protected type within a
811 precondition of a protected operation. This is needed because
812 the original precondition has been analyzed in the context of
813 the protected declaration, but in the body of the operation
814 references to the discriminants have been replaved by references
815 to the discriminants of the target object, and these references
816 are only created when expanding the protected body.
818 2017-09-08 Yannick Moy <moy@adacore.com>
820 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
823 2017-09-08 Ed Schonberg <schonberg@adacore.com>
825 * exp_attr.adb (Build_Record_VS_Func): If the record is an
826 unchecked union, do not emit checks for its (non-existent)
827 discriminants, or for variant parts that depend on them.
829 2017-09-08 Justin Squirek <squirek@adacore.com>
831 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
832 Find_Comparison_Type.Try_One_Interp): Add check for generic
835 2017-09-08 Arnaud Charlet <charlet@adacore.com>

839 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
840 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
841 remaining references to AAMP_On_Target.
843 2017-09-08 Ed Schonberg <schonberg@adacore.com>

852 interfaces using the underlying type to handle limited-withed
854 (Attribute_Tag): Check class-wide type interfaces using
855 the underlying type to handle limited-withed types.
857 2017-09-08 Ed Schonberg <schonberg@adacore.com>
859 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
860 over a subtype of a type with a static predicate, taking into
861 account the predicate function of the parent type and the bounds
862 given in the loop specification.
863 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
864 a loop specification that is a subtype indication whose type mark
865 is a type with a static predicate, inherit predicate function,
866 used to build case statement for rewritten loop.
868 2017-09-08 Justin Squirek <squirek@adacore.com>
870 * lib-load.adb: Modify printing of error message to exclude file
873 2017-09-08 Arnaud Charlet <charlet@adacore.com>
875 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
876 don't inline subprograms declared in both visible and private
878 (In_Package_Spec): previously In_Package_Visible_Spec; now
879 detects subprograms declared both in visible and private parts
882 2017-09-08 Ed Schonberg <schonberg@adacore.com>
884 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
885 the type is an anonymous array in an object declaration, whose
886 component type has an invariant, use the object declaration
887 as the insertion point for the invariant procedure, given that
888 there is no explicit type declaration for an anonymous array type.
890 2017-09-08 Bob Duff <duff@adacore.com>
892 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

898 2017-09-08 Justin Squirek <squirek@adacore.com>
900 * lib-load.adb (Load_Main_Source): Add error output in the case a
901 source file is missing.
903 2017-09-08 Bob Duff <duff@adacore.com>
906 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
907 Default_WCEM by default (i.e. if the encoding is not specified
910 2017-09-08 Bob Duff <duff@adacore.com>
912 * s-trasym.ads (Hexa_Traceback): If
913 Suppress_Hex is True, print "..." instead of a hexadecimal
915 * s-trasym.adb: Ignore No_Hex in this version.
918 2017-09-08 Bob Duff <duff@adacore.com>
920 * debug.adb: Minor reformatting.
922 2017-09-08 Bob Duff <duff@adacore.com>
924 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
925 code so it doesn't trigger an "uninit var" warning.

929 * s-hibaen.ads: Remove obsolete file.
931 2017-09-08 Arnaud Charlet <charlet@adacore.com>

937 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
939 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
940 allow calls in the context of package spec (for pragma
941 Initializes) and bodies (for pragma Refined_State).
943 2017-09-08 Bob Duff <duff@adacore.com>

948 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
950 * debug.adb (dA): Adjust comment.
951 * gnat1drv.adb (Gnat1drv): Likewise.
952 * opt.ads (List_Representation_Info_Extended): New variable.
953 * repinfo.adb (List_Record_Info): Split implementation into...
954 (Compute_Max_Length): ...this. Recurse on records if requested.
955 (List_Record_Layout): Likewise.
956 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
957 statement, accept '0' and set List_Representation_Info_Extended
959 * usage.adb (Usage): Document new -gnatRe variant.
961 2017-09-08 Ed Schonberg <schonberg@adacore.com>
963 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
964 Do not save the given entity in the global variable Default_Pool
965 if the pragma appears within a generic unit.
967 2017-09-08 Bob Duff <duff@adacore.com>
969 * errout.adb (Delete_Warning): Do not
970 decrement Warnings_Treated_As_Errors. This is called before
971 Warnings_Treated_As_Errors has been incremented to account for
972 this warning. Decrementing it here can lead to negative values
973 of Warnings_Treated_As_Errors, raising Constraint_Error in
974 checks-on builds, and causing the compiler to return an error
975 code in checks-off builds.
977 2017-09-08 Arnaud Charlet <charlet@adacore.com>
979 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
980 entities of named concurrent types as Ref_Id and not of anonymous
981 concurrent objects (because callers already know when a conversion
982 is necessary and can easily do it); also, do not expect protected
983 types or protected objects as Context_Id (because no flow-related
984 SPARK pragmas are attached there); reflect these changes in a
985 more precise comment.
987 2017-09-08 Olivier Hainque <hainque@adacore.com>
989 * g-altive.ads: Add documentation.
991 2017-09-08 Bob Duff <duff@adacore.com>
993 * sem_util.ads, debug.adb: Minor comment fix.
994 * erroutc.ads: Comment fix.
996 2017-09-08 Ed Schonberg <schonberg@adacore.com>
998 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
999 for compatibility of component types of formal and actual in an
1000 instantiation of a child unit, when the component type of the
1001 formal is itself a formal of an enclosing generic.
1003 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1005 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1006 sem_prag.adb to make it available for GNATprove; for concurrent
1007 types replace custom scope climbing with Scope_Same_Or_Within; for
1008 single concurrent objects add scope climbing (with Scope_Within),
1009 which was not there (that's the primary semantic change of this
1010 commit); also, when comparing a single concurrent object with
1011 its corresponding concurrent type rely on equality of types,
1012 not of objects (because that's simpler to code).
1013 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1014 (Analyze_Global_Item): adjust special-casing of references to the
1015 current instance of a concurrent unit in the Global contracts
1016 of task types and single tasks objects; similar for references
1017 in the protected operations and entries of protected types and
1018 single protected objects (in all these cases the current instance
1019 behaves as an implicit parameter and must not be mentioned in
1020 the Global contract).
1022 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1024 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1025 function calls returning a record within a subprogram call,
1028 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1030 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1031 name that designates the current instance of a child unit in its
1032 own body and appears as the prefix of a reference to an entity
1033 local to the child unit.
1034 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
1037 2017-09-08 Yannick Moy <moy@adacore.com>

1044 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
1045 warnings on internal units in configurable run time mode.
1047 2017-09-08 Bob Duff <duff@adacore.com>
1049 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
1050 representation items from interfaces that the derived type
1051 implements, not just from the parent type.
1052 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
1053 this to return an empty list when there are no interfaces.
1054 * einfo.ads, sem_ch13.adb: Minor comment fixes.
1055 * sem_attr.adb: Minor comment fix.

1582 debugging printouts comparing the two orders." Now it means
1583 "do not run Elab_New." This is of use if there are bugs that
1584 cause Elab_New to crash.
1585 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1587 * ali.ads (Elab_Position): Change type to Nat, to avoid various

1593 reference to SPARK RM.
1595 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1597 * layout.adb: Use SSU short hand consistently throughout the file.

1601 * freeze.adb (Freeze_Record_Type)
1602 <Sized_Component_Total_Round_RM_Size>: New local variable to
1603 accumulate the rounded RM_Size of components. Update it for
1604 every component whose RM_Size is statically known. Add missing
1605 guard to check that bit packing is really required before issuing
1606 the error about packing. Swap condition for clarity's sake.
1607 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

1628 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1630 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1631 entity of a mutable type and the right-hand side is a conditional
1632 expression, resolve the alternatives of the conditional using
1633 the base type of the target entity, because the alternatives
1634 may have distinct subtypes. This is particularly relevant if
1635 the alternatives are aggregates.
1637 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1639 * checks.adb (Apply_Predicate_Check): If the expression is an
1640 aggregate that is the RHS of an assignment, apply the check to
1641 the LHS after the assignment, rather than to the aggregate. This
1642 is more efficient than creating a temporary for the aggregate,
1643 and prevents back-end crashes when the aggregate includes a
1644 dynamic "others' association.
1646 2017-09-06 Yannick Moy <moy@adacore.com>
1648 * sem_ch12.adb (Analyze_Instance_And_Renamings):

1655 message for calls inside expression function, unless body was
1656 seen and is candidate for inlining.

1662 body. do not freeze the formals of the generic unit.
1664 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1666 * errout.adb (Error_Msg): Separate the
1667 treatment for warning vs. style messages in inlinings and
1668 instantiations. Prevents blowups on calls to Warn_Insertion for
1669 style messages, which should not be called in that case because
1670 Warning_Msg_Char is not set.
1672 2017-09-06 Justin Squirek <squirek@adacore.com>
1674 * sem_prag.adb (Check_VFA_Conflicts): Created
1675 to group all Volatile_Full_Access checks relating to other
1676 representation pragmas (Mark_Component_Or_Object): Created
1677 to centeralize the flagging of attributes for the record type
1678 component case, a pragma applied individually to a component, and
1680 (Process_Atomic_Independent_Shared_Volatile):
1681 Add propagation of certain pragmas to record components and move
1682 evaluation of VFA checks

1695 2017-09-06 Bob Duff <duff@adacore.com>
1697 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1698 that is a proper body corresponding to a stub, we defer the
1699 adjustment of the sloc until after the correct adjustment has
1700 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1701 the adjustment, because it will be outside the range in (the old,
1702 incorrect) S_Adjustment.
1703 * inline.adb: Use named notation for readability and uniformity.
1704 * sinput-l.adb: Minor improvements to debugging output printed

1726 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1727 checking for container loops so that the index cursor is not
1728 directly changable by the user with the use of E_Loop_Parameter.

1775 the actual is declared in the same unit and has a corresponding
1776 body, to prevent the current instance from being frozen before

1801 missing case of controlled generalized indexing.
1802 (Is_Source_Object): Use routine Strip to remove indirections.
1803 (Strip): New routine.
1805 2017-09-06 Bob Duff <duff@adacore.com>
1807 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1808 we include the proper header. Otherwise, we just declare the necessary
1809 things from the capabilities library. This is so we can build on
1810 machines without that library, while still enabling that library.
1811 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1812 simply return 0 if the library is not present, or not included

1828 has no parameter specification and no entry index, use the entry name
1829 as the end of the generated SCO statement.
1831 2017-09-06 Steve Baird <baird@adacore.com>
1833 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1834 uses of 'Image and related attributes as having side effects in
1835 order to avoid replicating such uses.
1836 * pprint.ads (Expression_Image) Add new generic formal flag
1837 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1838 (eventually) override the default.
1839 * pprint.adb (Expression_Image) If the new flag is set, then
1840 suppress the ".all" suffix when displaying a dereference whose
1841 prefix is a use of a value-capturing compiler temp of the sort
1842 generated by Expr_Util.Remove_Side_Effects .

1860 2017-09-06 Yannick Moy <moy@adacore.com>
1862 * sem_ch3.adb (Derived_Type_Declaration): Use
1863 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1865 2017-09-06 Javier Miranda <miranda@adacore.com>
1867 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1870 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1872 * sem_dim.adb (Analyze_Dimension): In an instance, a type

1879 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

1900 2017-09-06 Yannick Moy <moy@adacore.com>
1902 * freeze.adb (Check_Inherited_Conditions): Rewriting
1903 of inherited preconditions and postconditions should only occur
1904 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1905 be confused with SPARK_Mode being On.
1907 2017-09-06 Yannick Moy <moy@adacore.com>

1922 (Entity_Table_Size): New constant.
1923 (Entity_Hash): New function.
1924 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1925 (Is_Subprogram_Ref): Rename into...
1926 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1927 the table instead of bailing out on them. Scan the value of constants
1928 if it is not known at compile time.
1929 (Contains_Subprograms_Refs): Rename into...
1930 (Scan_Subprogram_Refs): ...this.
1931 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1932 Is_Public flag on subprograms if they are not actually referenced.
1933 (Hide_Public_Entities): Beef up comment on the algorithm.
1934 Reset the table of subprograms on entry.
1936 2017-09-06 Yannick Moy <moy@adacore.com>

1990 2017-09-06 Bob Duff <duff@adacore.com>
1992 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint

2021 * sem_type.adb (Interface_Present_In_Ancestor): Within an
2022 expression function, or within a spec expression (default value,
2023 etc) a reference to an incomplete type is legal: legality of

2025 object or subprogram) is frozen.
2027 2017-09-06 Gary Dismukes <dismukes@adacore.com>
2029 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

2041 we can use modern Ada in this package.
2042 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2043 Move Ada.Command_Line.Response_File to System.Response_File,
2044 and make Ada.Command_Line.Response_File into a rename of
2045 System.Response_File. This is to avoid having gnatbind depend
2046 Ada.Command_Line, which would damage the bootstrap process now
2047 that Ada.Command_Line contains modern Ada (the raise expression).
2048 * gnatbind.adb: Avoid dependence on
2049 Ada.Command_Line. Depend on System.Response_File instead
2050 of Ada.Command_Line.Response_File. Change one call to
2051 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2052 to Ada.Command_Line.Argument_Count to use Arg_Count.

2063 "Assert(False)" with "return Iter", because if an iterable

2065 overriding or inherited default iterator.
2067 2017-09-06 Yannick Moy <moy@adacore.com>
2069 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

2078 (Write_Field15_Name): Update the output for

2192 not retrievable as selected components.
2194 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2196 * sem_util.adb (Needs_One_Formal): The first formal of such a

2236 not visible in the object.
2237 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2238 side may be derived from that of the left-hand side (as in the
2239 case of an assignment with a change of representation) so the
2240 discriminant to be used in the retrieval of the value of the
2241 component must be the entity in the type of the right-hand side.

2816 * exp_ch6.adb (Expand_Call_Helper): When locating the
2817 accessibility entity created for an access parameter, handle
2818 properly a reference to a formal of an enclosing subprogram. if
2819 the reference appears in an inherited class-wide condition, it
2820 is the rewriting of the reference in the ancestor expression,
2821 but the accessibility entity must be that of the current formal.
2823 2017-05-02 Javier Miranda <miranda@adacore.com>
2825 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

2861 procedure body for a local (sub)type declaration within a
2862 predicate function. Invariant checks do not apply to these, and
2863 the expansion of the procedure will happen in the wrong scope,
2864 leading to misplaced freeze nodes.
2866 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2868 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2869 to analyze generated actions. If the main unit is a body,

2874 * einfo.adb (Declaration_Node): flip branches of

2905 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2906 Refine predicate for the case where the primitive operation
2907 is a renaming of equality. An overriding operation that is
2908 a user-defined renaming of predefined equality inherits its
2909 slot from the overridden operation. Otherwise it is treated
2910 as a predefined op and occupies the same predefined slot as
2911 equality. A call to it is transformed into a call to its alias,
2912 which is the predefined equality. A dispatching call thus uses
2913 the proper slot if operation is further inherited and called
2914 with class-wide arguments.
2916 2017-05-02 Justin Squirek <squirek@adacore.com>
2918 * errout.adb (Set_Msg_Text): Add a case to switch the message

2951 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2952 statement if the initialization call is a null procedure, as
2953 can happen with a controlled type with no explicit Initialize
2954 procedure, or an array of such.

2956 controlled components that has a trivial Initialize procedure,
2957 insert declaration for finalization counter after object

2960 finalization block and attendant declarations if component has
2961 a trivial Initialize procedure.

2993 2017-05-02 Gary Dismukes <dismukes@adacore.com>
2995 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
2996 parameter Array_Comp to indicate the case of an array object
2997 with null-excluding components.
2998 * checks.adb (Null_Exclusion_Static_Checks):
2999 Call Compile_Time_Constraint_Error instead of
3000 Apply_Compile_Time_Constraint_Error in the component case. Also
3001 call that when Array_Comp is True, with an appropriate warning for
3002 the array component case. Only create an explicit initialization
3003 by null in the case of an object of a null-excluding access type
3004 (and no longer do that in the component case).
3005 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3006 Array_Comp defaulted to False. Pass Empty for the Comp
3007 actual when calling Null_Exclusion_Static_Checks in the case
3008 where Comp_Decl matches Object_Decl, because we don't have a
3009 component in that case. In the case of an object or component
3010 of an array type, pass True for Array_Comp on the recursive call

3015 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3016 compute the linux priority from the Ada priority. Call this everywhere
3017 required. In particular, the previous version was not doing this
3018 computation when setting the ceiling priority in various places. It
3019 was just converting to C.int, which results in a ceiling that is off
3022 2017-05-02 Ed Schonberg <schonberg@adacore.com>

3041 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3042 here from exp_ch9, to recognize objects whose creation requires
3043 dynamic allocation, so that the proper warning can be emitted
3044 when restriction No_Implicit_Heap_Allocation is in effect.
3045 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
3046 to emit proper warning when an object that requires dynamic

3112 (Expand_SPARK): Call new
3113 function to expand operator /=.
3115 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3117 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3118 Simplify the expression for a fixed-fixed division to remove
3119 divisions by constants whenever possible, as an optimization
3120 for restricted targets.

3124 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3126 2017-05-02 Bob Duff <duff@adacore.com>
3128 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3129 to find primitive ops, instead of using an Identifier that will
3130 later be looked up. This is necessary because these ops are not
3131 necessarily visible at all places where we need to call them.
3132 * exp_util.ads: Minor comment fix.
3134 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3136 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3137 references are fully conformant if they are both expansions
3138 of the discriminant of a protected type, within one of the
3139 protected operations. One occurrence may be expanded into a
3140 constant declaration while the other is an input parameter to
3141 the corresponding generated subprogram.

3145 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3146 recursivly searching composite-types for null-excluding access
3147 types and verifying them.
3148 (Analyze_Object_Declaration): Add a
3149 call to Check_Null_Excluding_Components for static verification
3150 of non-initialized objects.
3151 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3152 a parameter for a composite-type's component and an extra case
3153 for printing component information.

3171 array components specially.
3173 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3175 * sem_ch8.adb (Premature_Usage): If the premature usage of
3176 an entity is as the expression in its own object decaration,
3177 rewrite the reference as Any_Id to prevent cascaded errors or
3178 compiler loops when such an entity is used in an address clause.
3180 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3182 * gcc-interface/decl.c (components_to_record): Add missing guard.

3187 Put back pending fields onto the regular list if the misalignment
3188 happens to cancel itself.
3190 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3192 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3193 controlling actual in a prefixed call, preserve the original node
3194 information if the prefix itself has been rewritten, for ASIS use.
3196 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3198 * exp_ch6.adb (Insert_Post_Call_Actions):
3199 Code clean up. Insert the post-call actions after an enclosing
3200 procedure call when N denotes a function call and appears as an
3201 actual parameter in the procedure call.
3203 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3205 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3206 for the component, also reject the attribute if the component
3207 doesn't end on a byte boundary and its scalar storage order is
3208 different from that of the enclosing record type.
3210 2017-04-28 Javier Miranda <miranda@adacore.com>
3212 * atree.ads (Info_Messages): Removed.

3242 2017-04-28 Bob Duff <duff@adacore.com>
3244 * sem_util.ads, sem_util.adb (Might_Raise): New function
3245 that replaces Is_Exception_Safe, but has the opposite
3246 sense. Is_Exception_Safe was missing various cases -- calls inside
3247 a pragma Debug, calls inside an 'if' or assignment statement,
3248 etc. Might_Raise now walks the entire subtree looking for things
3250 * exp_ch9.adb (Is_Exception_Safe): Remove.
3251 (Build_Protected_Subprogram_Body): Replace call to
3252 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3253 constants where possible).
3254 * exp_ch7.adb: Rename Is_Protected_Body -->
3255 Is_Protected_Subp_Body. A protected_body is something different
3258 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

3284 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3285 Interrupt_Handler and Attach_Handler): Generate reference
3286 to protected operation to prevent spurious warnings about
3287 unreferenced entities. Previous scheme failed with style checks
3290 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3292 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3293 that follows an expression function must not be relocated to
3294 the generated body, because it applies to the code that follows.
3296 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3298 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3299 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3300 code that might violate the more stringent checking for 'Access
3301 introduced in Ada 2005.
3303 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3305 * a-cforse.adb: minor style fix in comment.
3307 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3309 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3310 initialize Block_Decls variable.
3311 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3312 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

3321 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3323 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3325 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3326 node between access types, freeze the designated type as well,
3327 so that dispatch table pointers are created in the proper scope,
3328 and not in the constructed body of the expression function.
3330 2017-04-28 Bob Duff <duff@adacore.com>
3332 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3333 value makes large compilations faster, but small compilations slower.
3335 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3337 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3339 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3341 * erroutc.adb (Compilation_Errors): Do not consider info messages

3349 suitable warnings when warnings must be treated as errors.
3351 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3353 * warnsw.ads: Minor fix for incorrect wording in comment.
3355 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3357 * sem_res.adb (In_Instance_Code): New predicate in
3358 Valid_Conversion, to determine whether a type conversion appears
3359 as (or within) an actual for a formal object. Type conversions
3360 in instances are not rechecked in Valid_Conversion because
3361 visibility changes between generic location andi instance may
3362 lead to spurious errors, but conversions within an actual must be
3363 fully checked, and they are not fully resolved when pre-analyzing
3366 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3368 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3369 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3370 of the relocated node will have mangled Parent pointers.
3371 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3372 tables used in conjunction with entity and itype replication.
3373 (Visit_Entity): Rewrite the restriction on which entities
3374 require duplication. The restriction now includes all types.

3408 (Restore_Warnings): Likewise.
3409 (Save_Warnings): Likewise.
3410 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3411 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3412 components_to_record.
3413 (gnu_field_to_gnat): New function.
3414 (warn_on_field_placement): Likewise.
3415 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3416 parameters. Rename local variables and adjust recursive call.
3417 Rework final scan of the field list and implement warnings on the
3418 problematic placement of specific sorts of fields.
3420 2017-04-27 Bob Duff <duff@adacore.com>
3422 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

3427 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3428 For efficiency, cache results of Is_Internal_File_Name and
3429 Is_Predefined_File_Name in the Units table. This avoids a lot
3430 of repeated text processing.
3432 2017-04-27 Emmanuel Briot <briot@adacore.com>
3434 * g-comlin.adb (Sort_Sections): remove useless test.
3436 2017-04-27 Claire Dross <dross@adacore.com>
3438 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3439 allow the use of regular equality over elements in contracts.
3440 (Formal_Model): Ghost package containing model functions that are
3441 used in subprogram contracts.
3442 (Current_To_Last): Removed, model functions should be used instead.
3443 (First_To_Previous): Removed, model functions should be used instead.
3444 (Strict_Equal): Removed, model functions should be used instead.
3445 (No_Overlap): Removed, model functions should be used instead.
3446 (Equivalent_Keys): Functions over cursors are removed. They were
3447 awkward with explicit container parameters.
3448 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3449 allow the use of regular equality over elements in contracts.
3450 (Formal_Model): Ghost package containing model functions that

3459 * gnat1drv.adb: Code cleanup.
3461 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3463 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3464 attribute reference in a post- condition is the subprogram to
3465 which the condition applies. If the condition is inherited
3466 by a type extension, the prefix becomes a reference to the
3467 inherited operation, but there is no need to create a wrapper
3468 for this operation, because 'Result is expanded independently
3469 when elaborating the postconditions.
3471 2017-04-27 Bob Duff <duff@adacore.com>
3473 * sinput.adb: Minor code cleanup.
3474 * namet.adb (Append): Create faster versions of
3475 Append(String) and Append(Name_Id) by using slice assignment
3477 * sem_util.adb (In_Instance): Speed this up by removing
3478 unnecessary tests; Is_Generic_Instance is defined for all
3480 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3481 Remove unused function.
3482 * alloc.ads (Nodes_Initial): Use a much larger value, because
3483 the compiler was spending a lot of time copying the nodes table
3484 when it grows. This number was chosen in 1996, so is rather out
3485 of date with current memory sizes. Anyway, it's virtual memory.
3486 Get rid of Orig_Nodes_...; use Node_... instead.
3487 * atree.adb (Lock): Do not release the Nodes tables; it's a
3489 Orig_Nodes_ ==> Nodes_
3490 * nlists.adb: Orig_Nodes_ ==> Nodes_
3491 * g-table.adb: Remove unused "with" clause.
3492 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3493 not be used by clients.
3494 * g-dyntab.adb (Last_Allocated): New function
3495 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3497 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3499 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3501 (Subtypes_Statically_Match): Remove duplicate check.

3521 processing for Ada 83 and instances.
3522 (Object_Access_Level): Merge the processing for indexed components
3523 and selected components.
3524 * uname.adb (Add_Node_Name): Merge the processing for stubs.

3535 of Expand_Dispatching_Call. If the denoted subprogram has a
3536 class-wide precondition, this is the only precondition that
3537 applies to the call, rather that the class-wide preconditions
3538 that may apply to the body that is executed. (This is specified
3541 2017-04-27 Yannick Moy <moy@adacore.com>
3543 * gnat1drv.adb (Adjust_Global_Switches): Issue
3544 a warning in GNATprove mode if the runtime library does not
3545 support IEEE-754 floats.
3547 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3549 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
3550 is itself inherited it does not carry any contract information,
3551 so examine its parent operation which is its Alias.
3553 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3555 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3556 prefix can be an object reference in which case Obj'Image (X)

4066 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4067 to improve readablity. Subprograms are separated between basic
4068 operations, constructors and properties. Universally quantified
4069 formulas in contracts are factorized in independant functions
4070 with a name and a comment. Names of parameters are improved.
4072 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4074 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4076 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4078 * sem_res.adb (Resolve_Type_Conversion): Do not
4079 install a predicate check here since this is already done during
4080 the expansion phase. Verify whether the operand satisfies the
4081 static predicate (if any) of the target type.
4082 * sem_ch3.adb (Analyze_Object_Declaration): Do
4083 not install a predicate check if the object is initialized by
4084 means of a type conversion because the conversion is subjected

4108 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
4109 in gnat1 and gnatbind.
4110 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4111 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4119 modifications in functional containers.
4120 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4121 to improve readablity. Subprograms are separated between basic
4122 operations, constructors and properties. Universally quantified
4123 formulas in contracts are factorized in independant functions
4124 with a name and a comment. Names of parameters are improved.
4126 2017-04-27 Gary Dismukes <dismukes@adacore.com>

4152 2017-04-27 Tristan Gingold <gingold@adacore.com>
4154 * s-excmac-gcc.ads, s-excmac-gcc.adb,
4155 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
4158 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4160 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4161 the loop which detects potential enclosing transient scopes. The
4162 loop now terminates much earlier as transient scopes are bounded
4163 by packages and subprograms.
4165 2017-04-27 Claire Dross <dross@adacore.com>
4167 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4168 allow the use of regular equality over elements in contracts.
4169 (Cursor): Type is now public so that it can be used in
4171 (Formal_Model): Ghost package containing
4172 model functions that are used in subprogram contracts.
4173 (Current_To_Last): Removed, model functions should be used
4175 (First_To_Previous): Removed, model functions should
4177 (Strict_Equal): Removed, model functions
4178 should be used instead.
4179 (Append): Default parameter value
4180 replaced by new wrapper to allow more precise contracts.

4198 Default_Initial_Condition procedure of a type under the SPARK
4199 elaboration checks umbrella.
4201 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

4210 * adaint.c (__gnat_get_current_dir): Return 0 in length if
4212 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4213 exception if getcwd failed.

4218 entities with special prefix.
4220 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4222 * debug.adb Change the documentation of switch -gnatd.s.
4223 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4224 to manage the secondary stack when an enclosing scope already
4225 performs this functionality (aka relaxed management). Switch
4226 -gnatd.s may be used to force strict management in which case
4227 the block will manage the secondary stack unconditionally. Add
4228 a guard to stop the traversal when encountering a package or a
4231 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4233 * sem_res.adb (Resolve_Call): Refine further the handling of
4234 limited views of return types in function calls. If the function
4235 that returns a limited view appears in the current unit,
4236 we do not replace its type by the non-limited view because
4237 this transformation is performed int the back-end. However,
4238 the type of the call itself must be the non-limited view, to
4239 prevent spurious resolution errors.
4241 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4243 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4244 Removed, proposed implementation using generics for class-wide
4245 preconditions proved impractical.
4246 (Class_Wide_Clone): New attribute of subprogram. Designates
4247 subprogram created for primitive operations with class-wide
4248 pre/postconditions that contain calls to other primitives. The
4249 clone holds the body of the original primitive, but the
4250 pre/postonditions do not apply to it. The original body is
4251 rewritten as a wrapper for a call to the clone.
4252 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4253 the flag is set, no code for the corresponding pre/postconditions
4254 is inserted into its body.
4256 2017-04-27 Bob Duff <duff@adacore.com>
4258 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

4269 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
4270 (Remove): New function that removes an element from a set.
4271 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
4272 (Remove): New function that removes an element from a sequence.
4273 (Insert): New function that adds anywhere in a sequence.

4286 of attribute 'Result is not considered a violation of pragma
4289 2017-04-27 Justin Squirek <squirek@adacore.com>
4291 * cstand.adb (Create_Standard): Correctly set
4292 Directly_Designated_Type for Any_Access.

4302 private child of Ada.Containers used to implement all functional
4304 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4305 child of Ada.Containers. It provides functional indefinite unbounded
4306 maps which can be used as high level models for specification
4308 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4309 child of Ada.Containers. It provides functional indefinite unbounded
4310 sets which can be used as high level models for specification
4312 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4313 child of Ada.Containers. It provides functional indefinite unbounded
4314 vectors which can be used as high level models for specification
4316 * Makefile.rtl: Add new packages.
4317 * impunit.adb: Add new packages.
4319 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4321 * sem_ch4.adb: Minor reformatting.
4323 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4325 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4326 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4327 point type actual that has user-defined arithmetic primitives,
4328 when there is a previous actual for a formal package that defines
4329 a fixed-point type with the parent user-defined operator.
4331 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4333 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4334 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4335 the component type allows range checks.
4337 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4339 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4340 corresponding declaration, because formal derived types are
4341 rewritten as private extensions.
4343 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4345 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4346 dimensions of operands if node has been analyzed already, because
4347 previous analysis and dimension checking will have removed the
4348 dimension information from the operands.
4350 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4352 * debug.adb: Document the use of switch -gnatd.s.
4353 * einfo.ads Update the documentation on attribute
4354 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4355 the uses of these attributes from certain entities.
4356 * exp_ch7.adb (Make_Transient_Block): Reimplement the circuitry
4357 which determines whether the block should continue to manage
4358 the secondary stack.

4407 generating C code on complex case expressions.
4409 2017-04-25 Arnaud Charlet <charlet@adacore.com>
4411 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
4412 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4413 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4414 Ada_2012 instead of Ada_2005 to be compatible with the above
4416 * bindgen.adb: Silence new warning on pragma Ada_95.
4418 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4420 * checks.adb (Generate_Range_Check): Revert part of previous change.

4426 parameter association in a procedure call.
4428 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
4430 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4431 Fix spelling mistakes.
4433 2017-04-25 Bob Duff <duff@adacore.com>
4435 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4436 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4437 for source buffers. Fix misc obscure bugs.
4438 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4439 checking, for source buffers. Modify representation clause for
4440 Source_File_Record as appropriate. Move Source_File_Index_Table
4441 from spec to body, because it is not used outside the body.
4442 Move Set_Source_File_Index_Table into the private part, because
4443 it is used only in the body and in children. Use trickery to
4444 modify the dope in the generic instantiation case. It's ugly,
4445 but not as ugly as the previous method. Fix documentation.
4446 Remove obsolete code.
4447 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
4448 indexing in source buffers.

4462 expander is not active or when index/range checks are suppressed
4464 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4465 Remove variants that include a Supress parameter. These routines
4466 are never used, and were introduced before the current scope-based
4467 check suppression method.
4469 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>
4471 * prj-part.adb, cstreams.c, osint.adb, osint.ads: Remove VMS specific

4484 (Known_Null): Moved to Sem_Util.
4485 * sem_util.adb Add new enumeration type Null_Status_Kind.
4486 (Known_Non_Null): Moved from Exp_Util. Most of the logic in
4487 this routine is now carried out by Null_Status.
4488 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
4489 is now carried out by Null_Status.
4490 (Null_Status): New routine.

4496 * sem_ch6.adb (Analyze_Expression_Function): Do not report an
4497 error on the return type of an expression function that is a
4498 completion, if the type is derived from a generic formal type.
4500 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4518 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4519 the Internal_Source buffer. This removes the incorrect call to "="
4520 the customer noticed.
4521 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4522 eventually need to eliminate them altogether. Or else get rid
4523 of zero-origin addressing.

5032 to return if an interface type is encountered and add
5033 condition to convert the formal parameter to its class-wide

5091 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5092 dereference is introduced for the object, and the object is
5093 overloaded, do not check whether it is aliased, because it may
5094 include an implicit dereference.
5095 * sem_type.adb (Disambiguate): If two interpretations are access
5096 attribute types with the same designated type keep either of
5097 them and do not report an ambiguity. A true ambiguity will be
5100 2017-04-25 Bob Duff <duff@adacore.com>
5102 * a-numeri.ads: Change the encoding of Greek letter Pi from
5103 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5104 to indicate the encoding. We considered using a byte order mark
5105 (BOM), but that causes various trouble (misc software eats the
5106 BOM, if you have a patch with a BOM, then it's not at the start
5107 of the patch, so it's not a BOM, the BOM affects with-ing files,

5151 enforce legality rule on classwide preconditions inherited from
5152 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5153 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5154 subprogram need not be dispatching if it appears in a precondition
5155 for an abstract or null subprogram.
5157 2017-04-25 Gary Dismukes <dismukes@adacore.com>

5169 (Is_Predefined_File_Name): Likewise. Adjust comment.
5171 2017-04-25 Bob Duff <duff@adacore.com>
5173 * exp_aggr.adb (Component_Count): Protect the
5174 arithmetic from attempting to convert a value >= 2**31 to Int,
5175 which would otherwise raise Constraint_Error.
5177 2017-04-25 Bob Duff <duff@adacore.com>
5179 * opt.ads (Locking_Policy): Fix incorrect documentation. The

5203 Save and restore the value of global flag
5204 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

5206 the corresponding spec or the body must ignore all SPARK_Mode
5207 pragmas found within.
5208 (Analyze_Subprogram_Declaration): Mark
5209 the spec when it needs to ignore all SPARK_Mode pragmas found
5210 within to allow the body to infer this property in case it is
5211 instantiated or inlined later.
5212 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5213 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5214 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5215 when the corresponding spec also ignored all SPARK_Mode pragmas
5217 (Analyze_Package_Declaration): Mark the spec when

5248 Ignore_Pragma_SPARK_Mode.
5249 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5250 all SPARK_Mode pragmas defined within yields mode "off".
5252 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5271 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5273 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5274 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5275 variable and set it to True whenever the main hash table is
5276 populated. Short- circuit the Assoc function if it is false
5277 and add associated guards.
5279 2017-04-25 Olivier Hainque <hainque@adacore.com>
5281 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5282 specs without elaboration code that have an elaboration counter
5283 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5284 * sem_ch10.adb (Analyze_Compilation_Unit):
5285 Set_Elaboration_Entity_Required when requested to preserve
5286 control flow, to ensure the unit elaboration is materialized at
5287 bind time, resulting in the inclusion of the unit object file
5288 in the executable closure at link time.
5290 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5292 * exp_dbug.adb: In Debug_Renaming_Declaration,
5293 when dealing with indexed component, accept to produce a renaming
5294 symbol when the index is an IN parameter or when it is a name
5295 defined in an outer scope.
5297 2017-04-25 Yannick Moy <moy@adacore.com>
5299 * errout.adb (Error_Msg): Adapt continuation
5300 message in instantiations and inlined bodies for info messages.
5302 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5304 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5305 Use direct 4-character slice comparisons.
5307 pragma Inline. (Has_Suffix): Delete.
5308 (Is_Internal_File_Name):
5309 Test Is_Predefined_File_Name first.
5310 (Is_Predefined_File_Name):

5314 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5316 * checks.adb (Insert_Valid_Check): Code cleanup.
5317 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5318 (Expand_Actuals): Generate proper copy-back for a validation
5319 variable when it acts as the argument of a type conversion.
5320 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5321 predicate to operate on type qualifications.
5323 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5325 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5328 2017-04-25 Bob Duff <duff@adacore.com>
5330 * sem_prag.adb (No_Return): Give an error if the pragma applies
5331 to a body. Specialize the error for the specless body case,
5332 as is done for (e.g.) pragma Convention.
5333 * debug.adb: Add switch -gnatd.J to disable the above legality
5334 checks. This is mainly for use in our test suite, to avoid
5335 rewriting a lot of illegal (but working) code. It might also
5336 be useful to customers. Under this switch, if a pragma No_Return
5337 applies to a body, and the procedure raises an exception (as it
5338 should), the pragma has no effect. If the procedure does return,
5339 execution is erroneous.
5341 2017-04-25 Bob Duff <duff@adacore.com>
5343 * exp_ch6.adb (Expand_Actuals): This is the
5344 root of the problem. It took N as an 'in out' parameter, and in
5345 some cases, rewrote N, but then set N to Original_Node(N). So
5346 the node returned in N had no Parent. The caller continued
5347 processing of this orphaned node. In some cases that caused a
5348 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5349 and trips over the Empty Parent). The solution is to make N an
5350 'in' parameter. Instead of rewriting it, return the list of
5351 post-call actions, so the caller can do the rewriting later,
5352 after N has been fully processed.
5353 (Expand_Call_Helper): Move most of Expand_Call here. It has
5354 too many premature 'return' statements, and we want to do the
5355 rewriting on return.
5356 (Insert_Post_Call_Actions): New procedure to insert the post-call
5357 actions in the appropriate place. In the problematic case,
5358 that involves rewriting N as an Expression_With_Actions.
5359 (Expand_Call): Call the new procedures Expand_Call_Helper and
5360 Insert_Post_Call_Actions.
5362 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5364 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5365 properly type derived from generic formal types, to handle
5366 properly modified version of ACATS 4.1B B611017.
5368 2017-04-25 Javier Miranda <miranda@adacore.com>
5370 * exp_unst.adb (Subp_Index): Adding missing
5371 support for renamings and functions that return a constrained
5372 array type (i.e. functions for which the frontend built a
5373 procedure with an extra out parameter).
5375 2017-04-25 Pascal Obry <obry@adacore.com>
5377 * s-string.adb: Minor code clean-up.
5379 2017-04-25 Bob Duff <duff@adacore.com>

5384 function for Non_Blocking_Wait_Process.
5386 2017-04-25 Bob Duff <duff@adacore.com>
5388 * prep.adb (Preprocess): Remove incorrect
5389 Assert. Current character can be ASCII.CR.
5391 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5393 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5394 convention Stdcall, which has a number of exceptions. Convention
5395 is legal on a component declaration whose type is an anonymous
5396 access to subprogram.
5398 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5400 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5401 (Try_One_Prefix_Interpretation): Use the base type when dealing
5402 with a subtype created for purposes of constraining a private
5403 type with discriminants.
5405 2017-04-25 Javier Miranda <miranda@adacore.com>
5407 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

5409 dispatching primitives (Restore_Warnings): Restore warning on
5410 late dispatching primitives (Save_Warnings): Save warning on late
5411 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5412 to enable/disable this warning.
5413 (WA_Warnings): Set warning on late dispatching primitives.
5414 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5415 that its parent type has a private extension.
5416 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5418 * usage.adb: Document -gnatw.j and -gnatw.J.
5420 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5422 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5425 2017-04-25 Bob Duff <duff@adacore.com>
5427 * binde.adb (Validate): Do not pass dynamic strings
5428 to pragma Assert, because older compilers do not support that.
5430 2017-04-25 Bob Duff <duff@adacore.com>
5432 * s-fileio.adb (Close): When a temp file is
5433 closed, delete it and clean up its Temp_File_Record immediately,
5434 rather than waiting until later.
5435 (Temp_File_Record): Add File
5436 component, so Close can know which Temp_File_Record corresponds
5437 to the file being closed.
5438 (Delete): Don't delete temp files,
5439 because they are deleted by Close.
5440 (Open): Set the File component
5441 of Temp_File_Record. This requires moving the creation of the
5442 Temp_File_Record to the end, after the AFCB has been created.
5444 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5446 * checks.adb (Insert_Valid_Check): Do not generate
5447 a validity check when inside a generic.

5461 concerning inheritance of class-wide preconditions do not apply
5464 2017-04-25 Bob Duff <duff@adacore.com>
5466 * s-ficobl.ads: Minor comment fix.
5468 2017-04-25 Yannick Moy <moy@adacore.com>
5470 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5471 conversions from float to integer in GNATprove mode.
5472 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5473 to call Apply_Type_Conversion_Checks, so that range checks
5474 are properly positioned when needed on conversions, including
5475 when converting from float to integer. (Determine_Range): In
5476 GNATprove mode, take into account the possibility of conversion
5477 from float to integer.
5478 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5479 check on conversions from fixed-point to integer, not anymore
5480 on conversions from floating-point to integer, when in GNATprove
5483 2017-04-25 Yannick Moy <moy@adacore.com>
5485 * checks.adb (Determine_Range_R): Special case type conversions
5486 from integer to float in order to get bounds in that case too.
5487 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5488 mode, for computations involved in interval checking.

5502 * exp_attr.adb (Make_Range_Test): Add processing for validation
5503 variables to avoid extra reads and copies of the prefix.
5504 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5505 variables in order to reflect any changes done in the variable
5506 back into the original object.
5507 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5508 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5516 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5518 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5519 Analyze_Pre_Post_Condition, to implement the legality checks
5520 mandated by AI12-0131: Pre'Class shall not be specified for an
5521 overriding primitive subprogram of a tagged type T unless the
5522 Pre'Class aspect is specified for the corresponding primitive
5523 subprogram of some ancestor of T.
5525 2017-04-25 Bob Duff <duff@adacore.com>
5527 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5528 is redundant, set its Used_Operations to empty. This is only
5529 necessary for use clauses that appear in the parent of a generic
5530 child unit, because those use clauses get reanalyzed when we
5531 instantiate the generic, and we don't want the Used_Operations
5532 carried over from the original context (where it was probably
5535 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5537 * exp_ch6.adb: Minor reformatting.

5550 * sem_ch8.adb (Find_Type): For an attribute reference
5551 'Class, if prefix type is synchronized and previous errors
5552 have suppressed the creation of the corresponding record type,
5553 create a spurious class-wide for the synchonized type itself,
5554 to catch other misuses of the attribute

5562 if CodePeer_Mode is True, then don't generate the
5563 tag checks for the result of call to an instance of
5564 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5565 descendant of" check and the accessibility check).
5567 2017-04-25 Ed Schonberg <schonberg@adacore.com>

5576 (Expand_Concatenate): When optimization is enabled, also expand
5577 the operation out-of-line if the concatenation is present within
5578 the expression of the declaration of a library-level object and
5579 not only if it is the expression of the declaration.
5581 2017-04-25 Bob Duff <duff@adacore.com>
5583 * freeze.adb (Freeze_Object_Declaration): Do
5584 not Remove_Side_Effects if there is a pragma Linker_Section,
5585 because in that case we want static initialization in the
5586 appropriate section.
5588 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5590 * exp_dbug.adb: Minor rewording and reformatting.
5592 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5594 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5595 handle the proposed changes to rules concerning potentially
5596 unevaluated expressions, to include selected components that
5597 do not depend on discriminants, and indexed components with
5599 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5600 predicate in quantified expression, and fix bugs in the handling

5608 explaining why we don't need to walk all the chunks in order to
5609 compute the total size.
5611 2017-04-25 Bob Duff <duff@adacore.com>
5613 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length

5619 renaming entity for debug information, mark the entity as needing debug
5620 info if it comes from sources.
5622 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5624 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
5625 restriction converning the use of 'Address where the prefix is

5628 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5630 * exp_dbug.adb: In Debug_Renaming_Declaration,
5631 skip slices that are made redundant by an indexed component

5643 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5644 internal calls that appear in preconditions of protected
5645 operations, in default values for same, and in contract guards
5646 for contract cases in SPARK.
5648 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5650 * a-numaux.ads: Fix description of a-numaux-darwin
5652 (Double): Define to Long_Float.
5653 * a-numaux-vxworks.ads (Double): Likewise.
5654 * a-numaux-darwin.ads

5657 * a-numaux-x86.ads: Fix package description.
5658 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5659 (Reduce): Adjust and complete description. Call Is_Nan instead of
5660 testing manually. Use an integer temporary to hold rounded value.
5661 * a-numaux-darwin.adb (Reduce): Likewise.
5662 (Is_Nan): New function.
5664 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5666 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5667 on analysis of prefix whose type is a current instance of a
5668 synchronized type, but where the prefix itself is an entity that
5671 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5673 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5674 the identity of callable entities therein, because they have been
5675 properly resolved, and prefixed calls may have been rewritten
5678 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5680 * exp_ch3.adb (Build_Init_Statements): Convert
5681 the expression of the pragma/aspect Secondary_Stack_Size to
5682 internal type System.Parameters.Size_Type before assigning
5683 it to the Secondary_Stack_Size component of the task type's
5684 corresponding record.

5689 (etc) optimizations when the type is modular and the offsets
5692 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5694 * s-osinte-freebsd.ads: Minor comment tweaks
5696 2017-04-25 Javier Miranda <miranda@adacore.com>
5698 * urealp.adb (UR_Write): Reverse previous patch
5699 adding documentation on why we generate multiplications instead
5700 of divisions (needed to avoid expressions whose computation with
5701 large numbers may cause division by 0).
5703 2017-04-25 Bob Duff <duff@adacore.com>
5705 * erroutc.adb (Set_Specific_Warning_Off,
5706 Set_Warnings_Mode_Off): Use the correct source file for
5707 Stop. Was using Current_Source_File, which is only valid during
5708 parsing. Current_Source_File will have a leftover value from
5709 whatever file happened to be parsed last, because of a with_clause
5712 2017-04-25 Bob Duff <duff@adacore.com>
5714 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5715 to In_Predefined_Unit, but including GNAT units.
5716 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5717 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5718 because Should_Ignore_Pragma was not working reliably outside
5719 the parser, because Current_Source_File is not valid.
5720 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5721 * par-prag.adb: Call Should_Ignore_Pragma_Par.
5723 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

5753 2017-04-25 Justin Squirek <squirek@adacore.com>
5755 * exp_util.adb (Add_Interface_Invariants):
5756 Restored, code moved back from Build_Invariant_Procedure_Body.
5757 (Add_Parent_Invariants): Restored, code moved back from
5758 Build_Invariant_Procedure_Body.
5759 (Build_Invariant_Procedure_Body):
5760 Remove refactored calls and integrated code from
5761 Add_Parent_Invariants and Add_Interface_Invariants.
5763 2017-04-25 Johannes Kanig <kanig@adacore.com>
5765 * errout.adb (Output_Messages): Adjust computation of total
5767 * erroutc.adb (Error_Msg): In statistics counts, deal
5768 correctly with informational messages that are not warnings.
5769 * errutil.adb (Finalize): adjust computation of total errors.
5771 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

5780 2017-04-25 Justin Squirek <squirek@adacore.com>
5782 * sem_ch3.adb (Analyze_Declarations): Minor
5783 correction to comments, move out large conditional and scope
5784 traversal into a predicate.
5785 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5788 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5790 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5791 of prefix whose type is a current instance of a synchronized
5792 type. If the prefix is an object this is an external call (or
5793 requeue) that can only access public operations of the object. The
5794 previous predicate was too restrictive, and did not allow public
5795 protected operations, only task entries.
5797 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5799 * sem_ch5.adb, fname.adb: Minor reformatting.
5801 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5803 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5804 * einfo.ads Update the placement of
5805 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5807 (Is_Anonymous_Access_Type): New routine.
5808 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5809 master for an access type subject to pragma No_Heap_Finalization.
5810 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5811 allocated or deallocated does not finalization actions if the
5812 associated access type is subject to pragma No_Heap_Finalization.
5813 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5814 * par-prag.adb Pragma No_Heap_Finalization does not need special
5815 processing from the parser.
5816 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5817 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5818 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5819 No_Heap_Finalization.
5820 (Analyze_Pragma): Add processing for
5821 pragma No_Heap_Finalization. Update various error messages to
5822 use Duplication_Error.
5823 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5824 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5825 and corresponding pragma id.
5827 2017-04-25 Bob Duff <duff@adacore.com>
5829 * freeze.adb (Freeze_Record_Type): Use the
5830 underlying type of the component type to determine whether it's
5831 elementary. For representation clause purposes, a private type
5832 should behave the same as its full type.
5833 * fname.ads, fname.adb (Is_Predefined_File_Name):
5834 Make sure things like "system.ali" are recognized as predefined.
5836 2017-04-25 Javier Miranda <miranda@adacore.com>

5842 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5843 element iterator when the name is an overloaded function call,
5844 one of whose interpretations yields an array.
5846 2017-04-25 Bob Duff <duff@adacore.com>
5848 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5849 Is_Internal_Unit_Name): New functions for operating on unit
5850 names, as opposed to file names. There's some duplicated code
5851 with fname.adb, which is unfortunate, but it seems like we don't
5852 want to add dependencies here.
5853 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5854 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5855 is not a file name at all.
5856 * fname.ads, fname.adb: Document the fact that
5857 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5858 for ALI files, and fix the code so it works properly for ALI
5859 files. E.g. these should return True for "system.ali".
5861 2017-04-25 Justin Squirek <squirek@adacore.com>
5863 * exp_util.adb (Add_Invariant): Removed,
5864 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5865 and Add_Own_Invariant. (Add_Invariant_Check): Used
5866 for adding runtime checks from any kind of invariant.
5867 (Add_Inherited_Invariant): Generates invariant checks for
5868 class-wide invariants (Add_Interface_Invariants): Removed, code
5869 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

5871 Removed, code moved to Build_Invariant_Procedure_Body
5872 (Build_Invariant_Procedure_Body): Add refactored calls
5873 and integrated code from Add_Parent_Invariants and
5874 Add_Interface_Invariants.
5875 (Process_Type): Removed, the
5876 relavant code was inlined into both Add_Own_Invariant and
5877 Add_Inherited_Invariant.
5879 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5881 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5898 and Build_Invariant_Procedure_Declaration.
5899 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5900 and Build_Invariant_Procedure_Declaration from exp_ch7
5901 and break-out Is_Untagged_Private_Derivation from
5902 Build_Invariant_Procedure_Body.
5903 (Replace_Type_References):
5904 Append an extra parameter to allow for dispatching replacements
5905 and add the corrasponding logic.
5906 (Type_Invariant): Remove
5907 Replace_Typ_Refs and replace its references with calls to
5908 Replace_Type_References.
5909 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5911 2017-04-25 Bob Duff <duff@adacore.com>
5913 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5914 that returns True when appropriate.
5915 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5916 when compiling predefined files.
5917 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5918 "gnat.adc" should not be considered a predefined file name.
5919 That required (or at least encouraged) a lot of cleanup of global
5920 variable usage. We shouldn't be communicating information via
5921 the global name buffer.
5922 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5923 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5926 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5928 * osint.adb (Find_File): Handle properly a request for a
5929 configuration file whose name is a directory.

5943 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5944 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5945 Add String_To_Name with no side effects.
5947 2017-04-25 Justin Squirek <squirek@adacore.com>
5949 * sem_ch3.adb (Analyze_Declarations): Add
5950 additional condition for edge case.

5954 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5955 reserved words inside pragmas. This is necessary to allow the
5956 pragma name Interface to be used in pragma Ignore_Pragma.
5957 * par.adb: Minor comment fix.
5959 2017-04-25 Javier Miranda <miranda@adacore.com>
5961 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

5982 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
5983 the first pass over an assignment statement with target names,
5984 to prevent the generation of subtypes (such as discriminated
5985 record components)that may carry the target name outside of the
5986 tree for the assignment. The subtypes will be generated when
5987 the assignment is reanalyzed in full.
5988 (Analyze_Target_Name): Handle properly class-wide types.

5998 and resolve the triaged expression because all substitutions
5999 refer to the proper entities. Update the replacement of
6001 (Build_DIC_Procedure_Body): Add formal parameter
6002 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6003 are now only processed when freezing occurs. Build a body only

6020 properties of the private type to the full view in case the full
6021 view derives from a parent type and inherits a DIC pragma.
6022 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6023 DIC pragma is placed at the top of a declarative region.
6025 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6027 * a-tasatt.adb: Complete previous change and use an unsigned
6028 int to avoid overflow checks.
6030 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6032 * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
6033 the error message when the attribute reference is an actual in
6034 a call to a subprogram inherited from a generic formal type with
6035 unknown discriminants, which makes the subprogram and its formal
6036 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6038 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6040 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6043 2017-04-25 Bob Duff <duff@adacore.com>
6045 * sem_attr.adb (Type_Key): Add code in the
6046 recursive Compute_Type_Key to protect against fetching the source
6047 code for Standard, in case a component of the type is declared
6048 in Standard. There was already code to do this for the original
6049 type, but not for its components.
6051 2017-04-25 Javier Miranda <miranda@adacore.com>
6053 * exp_ch3.adb (Build_Initialization_Call): Handle
6054 subtypes of private types when searching for the underlying full
6055 view of a private type.

6059 * sem_res.adb (Set_Mixed_Mode_Operand): A universal
6060 real conditional expression can appear in a fixed-type context

6068 appears in the context of a unit U2 compiled for instantiation
6069 or inlining purposes, the body of U1 needs to be compiled as well.
6070 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
6071 context is a package declaration.
6072 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
6073 Analyze_Generic_Package_Declaration): ditto.

6747 (Check_Dependency_Clause): Properly detect a match between two
6748 'Result attributes. Update the various post-match cases to use

6812 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6813 an object declaration for an array type with a modular index type
6814 with the size of Long_Long_Integer. Special processing is needed
6815 in this case to compute reliably the size of the object, and
6816 eventually to raise Storage_Error, when wrap-around arithmetic
6817 might compute a meangingless size for the object.
6819 2017-01-23 Justin Squirek <squirek@adacore.com>

6826 * sem_res.adb (Resolve_Call): In the part of the code where
6827 it is deciding whether to turn the call into an indexed
6828 component, avoid doing so if the call is to an instance of
6829 Unchecked_Conversion. Otherwise, the compiler turns it into an
6830 indexed component, and resolution of that turns it back into a
6831 function call, and so on, resulting in infinite recursion.
6832 * sem_util.adb (Needs_One_Actual): If the first formal has a
6833 default, then return False.

6880 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6881 must be treated as delayed aspect even if the expression is

6935 returns a limited view of a type and at the point of the call the
6936 function is not declared in the extended main unit then replace
6937 it with the non-limited view, which must be available. If the
6938 called function is in the extended main unit then no action is
6939 needed since the back-end handles this case.

7164 so that the procedure can be used to check the array type
7166 (Freeze_Record_Type): In GNATprove mode, do
7167 not add the component invariants to the record type invariant
7168 procedure so that the procedure can be used to check the record

7191 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
7192 type, ie. a type whose component is a character type, and the

7195 type may be required in an enclosing operation.
7197 2017-01-19 Bob Duff <duff@adacore.com>
7199 * binde.adb, debug.adb: Enable new elaboration order algorithm
7200 by default. -dp switch reverts to the old algorithm.

7245 * exp_ch6.adb (Expand_Call): Remove side effects on
7246 actuals that are allocators with qualified expression since the
7247 initialization of the object is performed by means of individual
7248 statements (and hence it must be done before the call).

7252 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7253 (Build_Derived_Enumeration_Type): If the derived type inherits a
7254 dynamic predicate from its parent, the bounds of the type must
7255 freeze because an explicit constraint is constructed for the
7256 type and the corresponding range is elaborated now.

7307 wrong since we just issued a warning message.
7308 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
7309 these variables to be of subtype Nat instead of Int, because
7310 they should never be negative.

7341 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7343 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7344 selected component has a prefix that might be interpreted
7345 as a parameterless function call, but none of the candidate
7346 interpretations is parameterless, and there is a hidden homonym
7347 of the prefix that is a package.
7348 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7349 interpreted as a parameterless function call and its analysis
7350 fails, do not call Analyze_Selected_Component.

7354 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7356 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7357 calls to a newly-defined Scalar_Range_Of_Right_View function.
7359 2017-01-19 Arnaud Charlet <charlet@adacore.com>

7364 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7365 from repeated code of Traverse_Compilation_Unit.
7366 (Traverse_Declaration_Or_Statement): fixed detection of
7367 generic subprograms and packages; also, iteration over case
7368 statement alternatives rewritten to avoid testing if the first
7369 alternative is present (since it must be present due to Ada
7370 syntax restrictions).
7372 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7374 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
7375 returning by reference not just for subprogram body stubs,

7385 identifier nodes that do not come from source, to handle properly
7386 dimensionality check within an inlined body which inclddes both
7387 original operands and rewritten operands. This removes spurious
7388 dimensionality errors in the presence of front-end inlining,
7389 as well as in SPARK mode.
7391 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7430 * scil_ll.adb: Minor style fix in comment.
7431 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis

7462 * sem_ch6.adb (Cloned_Expression): New subprogram.
7463 (Freeze_Expr_Types): Complete previous patch since the expression
7464 of an expression-function may have iterators and loops with
7465 defining identifiers which, as part of the preanalysis of the
7466 expression, may be left decorated with itypes that will not be
7467 available in the tree passed to the backend.
7469 2017-01-13 Ed Schonberg <schonberg@adacore.com>

7487 Ensure that the input body is a subprogram body before trying to
7488 determine whether it denoted an expression function. Note that
7489 subprogram body stubs cannot denote expression functions.

7507 2017-01-13 Bob Duff <duff@adacore.com>
7509 * binde.adb (Elab_New): New elaboration order algorithm
7510 that is expected to cause fewer ABE issues. This is a work in
7511 progress. The new algorithm is currently disabled, and can be
7512 enable by the -dp switch, or by modifying the Do_Old and Do_New
7513 etc. flags and rebuilding. Experimental code is included to
7514 compare the results of the old and new algorithms.
7515 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7516 can have multiple of these tables, so the old and new algorithms
7518 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7519 parameter of type array. This avoids the global variable, and
7520 allows bounds checking (which is normally defeated by the tables
7521 packages). It also ensures that the Elab_Order is read-only
7523 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7524 subprograms that need it, as above.
7525 * debug.adb: Document new -dp switch. Modify doc of old -do
7527 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7528 and Bindgen. Move writing of closure (-R and -Ra switches)

7533 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7534 function is a completion, all entities referenced in the
7535 expression are frozen. As a consequence, a reference to an
7536 uncompleted private type from an enclosing scope is illegal.
7538 2017-01-13 Javier Miranda <miranda@adacore.com>
7540 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7541 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7542 expression function declaration that is a completion, its
7543 expression causes freezing (AI12-0103).
7545 2017-01-13 Vadim Godunko <godunko@adacore.com>
7547 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7593 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7595 * sem_util.ads, sem_util.adb (Choice_List): Move function here
7596 from sem_aggr.adb, for use elsewhere.

7601 Iterated_Component_Associations.
7602 (Gen_Loop): Generate proper loop for an
7603 Iterated_Component_Association: loop variable has the identifier
7604 of the original association. Generate a loop even for a single
7605 component choice, in order to make loop parameter visible in
7607 (Flatten): An Iterated_Component_Association is not static.
7609 2017-01-13 Yannick Moy <moy@adacore.com>
7611 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7612 float exponentiation for statically known small negative values
7613 is the reciprocal of the exponentiation for the opposite value
7615 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):

7626 expression in delay statement as OK for volatile context.
7628 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7630 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7631 mode a choice that is a subtype with a static predicate is
7632 replaced by the values it covers. This transformation must not
7633 be performed in ASIS mode, to preserve the source for analysis.
7635 2017-01-13 Justin Squirek <squirek@adacore.com>
7637 * nlists.ads: Correct minor typo.
7639 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7649 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7650 and resolve the discrete choices and the expression of the
7652 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7653 Loop_Actions and Box_Present are attributes of
7654 N_Iterated_Component_Association nodes. Box_Present is always
7656 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7657 has a Discrete_Choices list, as specified in the RM. A
7658 Component_Association for aggregate uses instead a Choices list.
7659 We have to live with this small inconsistency because the new
7660 construct also has a defining identifier, and there is no way
7661 to merge the two node structures.
7663 2017-01-13 Yannick Moy <moy@adacore.com>
7665 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
7666 list of pragmas to remove. Remove pragmas from the list of

7673 Analyze_Declarations, to analyze and resolve the expressions of
7674 aspect specifications in the current declarative list, so that
7675 the expressions have proper entity and type info. This is needed
7676 for ASIS when there is no subsequent expansion to generate this
7677 semantic information.
7678 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7679 original expression, to suppress cascaded errors when expression
7680 has been constant-folded.
7681 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7682 ASIS mode, because there is no subsequent expansion to decorate
7685 2017-01-13 Yannick Moy <moy@adacore.com>
7687 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
7688 New function to detect when a call may be inlined or not in
7690 (Expand_Inlined_Call): Ensure that a temporary
7691 is always created in the cases where a type conversion may be
7692 needed on an input parameter in GNATprove mode, so that GNATprove
7693 sees the check to perform.
7694 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7695 when not applicable due to actual requiring type conversion
7696 with possible check but no temporary value can be copied for
7697 GNATprove to see the check.
