323 2017-09-08 Yannick Moy <moy@adacore.com>
325 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
326 return the entity associated with the call.
327 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
328 Replace the internal Get_Function_Id with the new
329 Sem_Aux.Get_Called_Entity.
330 (Iterate_Call_Parameters): New
331 procedure to iterate on formals and actuals at the same time.
332 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
333 Set SPARK_Mode from spec when set, for analysis
334 of instance. Restore after analysis of instance.
335 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
336 set, for analysis of body instance. Restored automatically at
337 the end of the subprogram.
338 * gnat1drv.adb (Adjust_Global_Switches): Set
339 Check_Validity_Of_Parameters to False in GNATprove mode.
340 * opt.ads (Check_Validity_Of_Parameters): Document switch to
343 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
345 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
346 (New_Copy_Tree): ...there. Reset the hash tables only if they
347 were used in the previous invocation.
348 * s-htable.adb: Fix typo.
350 2017-09-08 Bob Duff <duff@adacore.com>
352 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
354 2017-09-08 Arnaud Charlet <charlet@adacore.com>
356 * sem_aggr.adb: minor style fix.
358 2017-09-08 Bob Duff <duff@adacore.com>
360 * sprint.adb (Write_Corresponding_Source): Ignore if there is
361 no current source file.
362 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
363 Print something helpful in case N is invalid.
364 * sprint.ads: Minor comment fix.
366 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
368 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
371 2017-09-08 Bob Duff <duff@adacore.com>
373 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
374 Ada_2020, along the same lines as the other Ada version pragmas.
376 2017-09-08 Gary Dismukes <dismukes@adacore.com>
378 * sem_ch12.adb: Minor typo fixes and reformatting.
380 2017-09-08 Yannick Moy <moy@adacore.com>
382 * sem_aggr.adb (Resolve_Record_Aggregate):
383 Rewrite bounds of aggregate subexpressions which may depend on
384 discriminants of the enclosing aggregate.
386 2017-09-08 Yannick Moy <moy@adacore.com>
388 * sem_ch5.adb: Prevent assertion failure on illegal code.
390 2017-09-08 Yannick Moy <moy@adacore.com>
392 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
393 calling Renamed_Entity on an entity which cannot be a renaming.
395 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
397 * exp_aggr.adb: Add with & use clause for Urealp.
398 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
399 elementary types instead of just discrete types.
400 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
401 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
402 Be prepared for the FP zero value in the memset case. Add small
405 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
407 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
410 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
412 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
413 of New_Copy because the latter leaves the syntactic structure of
414 the tree inconsistent (a child is accessible through two parents)
415 and prevents proper replication of itypes by subsequent calls
417 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
418 New_Copy because the latter leaves the syntactic structure of the
419 tree inconsistent (a child is accessible through two parents)
420 and prevents proper replication of itypes by subsequent calls
422 * sem_util.adb (In_Subtree): New routine.
423 (New_Copy_Tree): Reimplemented.

427 2017-09-08 Ed Schonberg <schonberg@adacore.com>
429 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
430 for aspect Default_Value is a static scalar value, but it does
431 not freeze the type. Yhis allows for subsequent representation
432 clauses for the type.
434 2017-09-08 Javier Miranda <miranda@adacore.com>
436 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
437 not add entries into the undefined reference table when we are
438 compiling with errors ignored.
440 2017-09-08 Ed Schonberg <schonberg@adacore.com>
442 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
443 check if the instance is within an enclosing instance body. The
444 formal package was legal in the enclosing generic, and is
445 legal in the enclosing instantiation. This optimisation may be
446 applicable elsewhere, and it also removes spurious errors that
447 may arise with on-the-fly processing of instantiations that
448 contain Inline_Always subprograms.
450 2017-09-08 Vincent Celier <celier@adacore.com>
452 * gnatcmd.adb: Disregard empty argument of GNAT driver.
454 2017-09-08 Justin Squirek <squirek@adacore.com>
456 * checks.adb (Insert_Valid_Check): Manually decorate
457 the generated temporary for range valdity checks.
459 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
461 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
463 2017-09-08 Justin Squirek <squirek@adacore.com>
465 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
466 case to handle underscore flags.
467 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
468 new procedure to handle underscores.
470 2017-09-08 Javier Miranda <miranda@adacore.com>
472 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
473 divisions with fixed point results to avoid generating twice
474 the runtime check on divide by zero.
475 * checks.adb (Apply_Divide_Checks): Ensure that operands are
476 not evaluated twice (once for their runtime checks and once for
477 their regular computation).
479 2017-09-08 Yannick Moy <moy@adacore.com>
481 * sem_prag.adb (Analyze_Part_Of): Add missing
482 return statements after issuing errors. Add detection of
483 out-of-order item and single concurrent type.

587 2017-09-08 Bob Duff <duff@adacore.com>
589 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
590 New routine to read the Tag robustly.

592 in the class-wide case, to call String_Input_Tag instead of
595 2017-09-08 Arnaud Charlet <charlet@adacore.com>
597 * s-rident.ads (Restriction_Id): reorder enum
598 literals, so that Pure_Barriers is no longer in range of the
599 Cunit_Boolean_Restrictions subtype.
601 2017-09-08 Nicolas Roche <roche@adacore.com>

610 accessibility check to an interface conversion, whose purpose
611 is to perform a pointer adjustment in a dispatching call.

613 when the actual is a construct that involves a dereference of an
614 expression that includes a formal of the enclosing subprogram,
615 In such cases, the accessibility level of the actual is that of
616 the corresponding formal, which is passed in as an additional
617 actual in the outer call.
619 2017-09-08 Bob Duff <duff@adacore.com>
621 * exp_intr.adb (Add_Source_Info): Do not decode
622 file names; they were not encoded in the first place.
624 2017-09-08 Bob Duff <duff@adacore.com>
626 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
627 exceptions instead of crashes. Check for absurdly long strings
628 and empty strings. Empty strings cause trouble because they can
629 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
630 be empty, which causes an array index out of bounds.
631 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions

692 under -gnat2020 flag, given that it is a future feature of
694 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
695 defining identifier as referenced to prevent spurious warnings:
696 corresponding loop is expanded into one or more loops whose
697 variable has the same name, and the expression uses those names
698 and not the original one.

776 cases covered by an assertion on expected BIP object

808 access to interface types. Remove also the accessibility check.
810 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
812 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
813 all the types that are referenced by the expression.
814 (Analyze_Expression_Function): Call Freeze_Expr_Types for
815 a completion instead of manually freezing the type of the
817 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
819 2017-09-08 Ed Schonberg <schonberg@adacore.com>
821 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
822 New procedure, auxiliary to Expand_Pragma_Check, to handle
823 references to the discriminants of a protected type within a
824 precondition of a protected operation. This is needed because
825 the original precondition has been analyzed in the context of
826 the protected declaration, but in the body of the operation
827 references to the discriminants have been replaved by references
828 to the discriminants of the target object, and these references
829 are only created when expanding the protected body.
831 2017-09-08 Yannick Moy <moy@adacore.com>
833 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
836 2017-09-08 Ed Schonberg <schonberg@adacore.com>

839 unchecked union, do not emit checks for its (non-existent)
840 discriminants, or for variant parts that depend on them.
842 2017-09-08 Justin Squirek <squirek@adacore.com>
844 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
845 Find_Comparison_Type.Try_One_Interp): Add check for generic
848 2017-09-08 Arnaud Charlet <charlet@adacore.com>

851 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
852 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
853 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
854 remaining references to AAMP_On_Target.
856 2017-09-08 Ed Schonberg <schonberg@adacore.com>
858 * style.adb: Fix typo.

868 the underlying type to handle limited-withed types.
870 2017-09-08 Ed Schonberg <schonberg@adacore.com>
872 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
873 over a subtype of a type with a static predicate, taking into
874 account the predicate function of the parent type and the bounds
875 given in the loop specification.
876 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
877 a loop specification that is a subtype indication whose type mark
878 is a type with a static predicate, inherit predicate function,
879 used to build case statement for rewritten loop.
881 2017-09-08 Justin Squirek <squirek@adacore.com>
883 * lib-load.adb: Modify printing of error message to exclude file
886 2017-09-08 Arnaud Charlet <charlet@adacore.com>
888 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
889 don't inline subprograms declared in both visible and private
891 (In_Package_Spec): previously In_Package_Visible_Spec; now
892 detects subprograms declared both in visible and private parts
895 2017-09-08 Ed Schonberg <schonberg@adacore.com>
897 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
898 the type is an anonymous array in an object declaration, whose
899 component type has an invariant, use the object declaration
900 as the insertion point for the invariant procedure, given that
901 there is no explicit type declaration for an anonymous array type.
903 2017-09-08 Bob Duff <duff@adacore.com>
905 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

911 2017-09-08 Justin Squirek <squirek@adacore.com>
913 * lib-load.adb (Load_Main_Source): Add error output in the case a
914 source file is missing.
916 2017-09-08 Bob Duff <duff@adacore.com>
919 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
920 Default_WCEM by default (i.e. if the encoding is not specified
923 2017-09-08 Bob Duff <duff@adacore.com>
925 * s-trasym.ads (Hexa_Traceback): If
926 Suppress_Hex is True, print "..." instead of a hexadecimal
928 * s-trasym.adb: Ignore No_Hex in this version.
931 2017-09-08 Bob Duff <duff@adacore.com>
933 * debug.adb: Minor reformatting.
935 2017-09-08 Bob Duff <duff@adacore.com>
937 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
938 code so it doesn't trigger an "uninit var" warning.

942 * s-hibaen.ads: Remove obsolete file.
944 2017-09-08 Arnaud Charlet <charlet@adacore.com>

952 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
953 allow calls in the context of package spec (for pragma
954 Initializes) and bodies (for pragma Refined_State).
956 2017-09-08 Bob Duff <duff@adacore.com>

961 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
963 * debug.adb (dA): Adjust comment.
964 * gnat1drv.adb (Gnat1drv): Likewise.
965 * opt.ads (List_Representation_Info_Extended): New variable.
966 * repinfo.adb (List_Record_Info): Split implementation into...
967 (Compute_Max_Length): ...this. Recurse on records if requested.
968 (List_Record_Layout): Likewise.
969 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
970 statement, accept '0' and set List_Representation_Info_Extended
972 * usage.adb (Usage): Document new -gnatRe variant.
974 2017-09-08 Ed Schonberg <schonberg@adacore.com>
976 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
977 Do not save the given entity in the global variable Default_Pool
978 if the pragma appears within a generic unit.
980 2017-09-08 Bob Duff <duff@adacore.com>
982 * errout.adb (Delete_Warning): Do not
983 decrement Warnings_Treated_As_Errors. This is called before
984 Warnings_Treated_As_Errors has been incremented to account for
985 this warning. Decrementing it here can lead to negative values
986 of Warnings_Treated_As_Errors, raising Constraint_Error in
987 checks-on builds, and causing the compiler to return an error
988 code in checks-off builds.
990 2017-09-08 Arnaud Charlet <charlet@adacore.com>
992 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
993 entities of named concurrent types as Ref_Id and not of anonymous
994 concurrent objects (because callers already know when a conversion
995 is necessary and can easily do it); also, do not expect protected
996 types or protected objects as Context_Id (because no flow-related
997 SPARK pragmas are attached there); reflect these changes in a
998 more precise comment.
1000 2017-09-08 Olivier Hainque <hainque@adacore.com>
1002 * g-altive.ads: Add documentation.
1004 2017-09-08 Bob Duff <duff@adacore.com>
1006 * sem_util.ads, debug.adb: Minor comment fix.
1007 * erroutc.ads: Comment fix.
1009 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1011 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
1012 for compatibility of component types of formal and actual in an
1013 instantiation of a child unit, when the component type of the
1014 formal is itself a formal of an enclosing generic.
1016 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1018 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1019 sem_prag.adb to make it available for GNATprove; for concurrent
1020 types replace custom scope climbing with Scope_Same_Or_Within; for
1021 single concurrent objects add scope climbing (with Scope_Within),
1022 which was not there (that's the primary semantic change of this
1023 commit); also, when comparing a single concurrent object with
1024 its corresponding concurrent type rely on equality of types,
1025 not of objects (because that's simpler to code).
1026 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1027 (Analyze_Global_Item): adjust special-casing of references to the
1028 current instance of a concurrent unit in the Global contracts
1029 of task types and single tasks objects; similar for references
1030 in the protected operations and entries of protected types and
1031 single protected objects (in all these cases the current instance
1032 behaves as an implicit parameter and must not be mentioned in
1033 the Global contract).
1035 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1037 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1038 function calls returning a record within a subprogram call,
1041 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1043 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1044 name that designates the current instance of a child unit in its
1045 own body and appears as the prefix of a reference to an entity
1046 local to the child unit.
1047 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
1050 2017-09-08 Yannick Moy <moy@adacore.com>
1052 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
1055 2017-09-08 Tristan Gingold <gingold@adacore.com>

1580 2017-09-06 Yannick Moy <moy@adacore.com>
1582 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
1583 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
1585 2017-09-06 Bob Duff <duff@adacore.com>
1587 * sem_ch8.adb: Change Assert to be consistent with
1590 2017-09-06 Bob Duff <duff@adacore.com>
1592 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1593 requested. Previously, the -do switch meant "run Elab_New and
1594 Elab_Old and use the order chosen by Elab_Old, possibly with
1595 debugging printouts comparing the two orders." Now it means
1596 "do not run Elab_New." This is of use if there are bugs that
1597 cause Elab_New to crash.
1598 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1600 * ali.ads (Elab_Position): Change type to Nat, to avoid various
1603 2017-09-06 Arnaud Charlet <charlet@adacore.com>
1605 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
1606 reference to SPARK RM.
1608 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1610 * layout.adb: Use SSU short hand consistently throughout the file.
1612 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1614 * freeze.adb (Freeze_Record_Type)
1615 <Sized_Component_Total_Round_RM_Size>: New local variable to
1616 accumulate the rounded RM_Size of components. Update it for
1617 every component whose RM_Size is statically known. Add missing
1618 guard to check that bit packing is really required before issuing
1619 the error about packing. Swap condition for clarity's sake.
1620 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.
1622 2017-09-06 Fedor Rybin <frybin@adacore.com>

1639 project manager sources.
1641 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1643 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1644 entity of a mutable type and the right-hand side is a conditional
1645 expression, resolve the alternatives of the conditional using
1646 the base type of the target entity, because the alternatives
1647 may have distinct subtypes. This is particularly relevant if
1648 the alternatives are aggregates.
1650 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1652 * checks.adb (Apply_Predicate_Check): If the expression is an
1653 aggregate that is the RHS of an assignment, apply the check to
1654 the LHS after the assignment, rather than to the aggregate. This
1655 is more efficient than creating a temporary for the aggregate,
1656 and prevents back-end crashes when the aggregate includes a
1657 dynamic "others' association.
1659 2017-09-06 Yannick Moy <moy@adacore.com>
1661 * sem_ch12.adb (Analyze_Instance_And_Renamings):
1662 Set variable to ignore SPARK_Mode in instance before the analysis
1663 of the generated package declaration.
1665 2017-09-06 Yannick Moy <moy@adacore.com>
1667 * sem_res.adb (Resolve_Call): Do not issue a
1668 message for calls inside expression function, unless body was
1669 seen and is candidate for inlining.
1671 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1673 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
1674 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
1675 body. do not freeze the formals of the generic unit.
1677 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1679 * errout.adb (Error_Msg): Separate the
1680 treatment for warning vs. style messages in inlinings and
1681 instantiations. Prevents blowups on calls to Warn_Insertion for
1682 style messages, which should not be called in that case because
1683 Warning_Msg_Char is not set.
1685 2017-09-06 Justin Squirek <squirek@adacore.com>
1687 * sem_prag.adb (Check_VFA_Conflicts): Created
1688 to group all Volatile_Full_Access checks relating to other
1689 representation pragmas (Mark_Component_Or_Object): Created
1690 to centeralize the flagging of attributes for the record type
1691 component case, a pragma applied individually to a component, and
1693 (Process_Atomic_Independent_Shared_Volatile):
1694 Add propagation of certain pragmas to record components and move
1695 evaluation of VFA checks
1697 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1699 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
1700 Do not warn on conditions that are not obeyed for Inline_Always
1701 subprograms, when assertions are not enabled.
1703 2017-09-06 Arnaud Charlet <charlet@adacore.com>
1705 * sem_util.adb (Unique_Entity): For abstract states return their
1708 2017-09-06 Bob Duff <duff@adacore.com>
1710 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1711 that is a proper body corresponding to a stub, we defer the
1712 adjustment of the sloc until after the correct adjustment has
1713 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1714 the adjustment, because it will be outside the range in (the old,
1715 incorrect) S_Adjustment.
1716 * inline.adb: Use named notation for readability and uniformity.
1717 * sinput-l.adb: Minor improvements to debugging output printed
1719 * sinput-l.ads (Create_Instantiation_Source): Minor comment
1722 2017-09-06 Vincent Celier <celier@adacore.com>
1724 * make.adb: Do not invoke gprbuild for -bargs -P.
1726 2017-09-06 Sylvain Dailler <dailler@adacore.com>
1728 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
1729 case when Op is of kind N_Qualified_Expression. In this case,
1730 the function is called recursively on the subexpression like in
1732 * make.adb: Minor reformatting
1734 2017-09-06 Justin Squirek <squirek@adacore.com>
1736 * einfo.adb (Set_Linker_Section_Pragma): Modify
1737 Set_Linker_Section_Pragma to be consistant with the "getter"
1738 Linker_Section_Pragma.
1739 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1740 checking for container loops so that the index cursor is not
1741 directly changable by the user with the use of E_Loop_Parameter.
1742 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
1743 * sem_warn.adb (Check_References): Revert previous change.
1745 2017-09-06 Bob Duff <duff@adacore.com>

1753 declarations to only consider valid uses of Global/Depends those on
1754 single concurrent objects.

1776 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
1777 gnatname.adb: Remove the Project Manager from the GNAT tools.
1778 * gcc-interface/Makefile.in: ditto.
1780 2017-09-06 Bob Duff <duff@adacore.com>
1782 * sem_util.ads: Minor comment fix.
1784 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1786 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
1787 Generate a freeze node for the actual of a formal package, if
1788 the actual is declared in the same unit and has a corresponding
1789 body, to prevent the current instance from being frozen before
1792 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1794 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.

1811 * exp_util.adb (Is_Controlled_Indexing): New routine.
1812 (Is_Displace_Call): Use routine Strip to remove indirections.
1813 (Is_Displacement_Of_Object_Or_Function_Result): Code clean up. Add a
1814 missing case of controlled generalized indexing.
1815 (Is_Source_Object): Use routine Strip to remove indirections.
1816 (Strip): New routine.
1818 2017-09-06 Bob Duff <duff@adacore.com>
1820 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1821 we include the proper header. Otherwise, we just declare the necessary
1822 things from the capabilities library. This is so we can build on
1823 machines without that library, while still enabling that library.
1824 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1825 simply return 0 if the library is not present, or not included
1828 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
1830 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

1841 has no parameter specification and no entry index, use the entry name
1842 as the end of the generated SCO statement.
1844 2017-09-06 Steve Baird <baird@adacore.com>
1846 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1847 uses of 'Image and related attributes as having side effects in
1848 order to avoid replicating such uses.
1849 * pprint.ads (Expression_Image) Add new generic formal flag
1850 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1851 (eventually) override the default.
1852 * pprint.adb (Expression_Image) If the new flag is set, then
1853 suppress the ".all" suffix when displaying a dereference whose
1854 prefix is a use of a value-capturing compiler temp of the sort
1855 generated by Expr_Util.Remove_Side_Effects .
1856 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

1870 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
1871 so that applies to any entity.
1873 2017-09-06 Yannick Moy <moy@adacore.com>
1875 * sem_ch3.adb (Derived_Type_Declaration): Use
1876 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1878 2017-09-06 Javier Miranda <miranda@adacore.com>
1880 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1883 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1885 * sem_dim.adb (Analyze_Dimension): In an instance, a type
1886 conversion takes its dimensions from the expression, not from
1888 (Dimensions_Of_Operand): Ditto.
1890 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1892 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
1893 null procedures when GNAT coverage is used, so that their (empty)
1894 bodies are properly covered.
1896 2017-09-06 Bob Duff <duff@adacore.com>
1898 * sem_ch13.adb (Resolve_Aspect_Expressions): If
1899 the entity is a type with discriminants, make the discriminants
1900 directly visible in aspect clauses.

1904 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
1905 Universal_Real and the context is a floating-point type, resolve
1906 both operands to the target type.

1913 2017-09-06 Yannick Moy <moy@adacore.com>
1915 * freeze.adb (Check_Inherited_Conditions): Rewriting
1916 of inherited preconditions and postconditions should only occur
1917 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1918 be confused with SPARK_Mode being On.
1920 2017-09-06 Yannick Moy <moy@adacore.com>

1933 on the procedure created to encapsulate the body.
1934 * sem_ch7.adb: Add with clause for GNAT.HTable.
1935 (Entity_Table_Size): New constant.
1936 (Entity_Hash): New function.
1937 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1938 (Is_Subprogram_Ref): Rename into...
1939 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1940 the table instead of bailing out on them. Scan the value of constants
1941 if it is not known at compile time.
1942 (Contains_Subprograms_Refs): Rename into...
1943 (Scan_Subprogram_Refs): ...this.
1944 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1945 Is_Public flag on subprograms if they are not actually referenced.
1946 (Hide_Public_Entities): Beef up comment on the algorithm.
1947 Reset the table of subprograms on entry.
1949 2017-09-06 Yannick Moy <moy@adacore.com>

1990 of protected subprograms and entries.
1991 * sem_util.adb, sem_util.ads (Is_Subp_Or_Entry_Inside_Protected):
1992 New function to detect when a subprogram of entry is defined
1993 inside a protected object.

2003 2017-09-06 Bob Duff <duff@adacore.com>
2005 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
2006 check back to the body, because SPARK is not yet ready for
2007 "or else raise Constraint_Error".

2034 * sem_type.adb (Interface_Present_In_Ancestor): Within an
2035 expression function, or within a spec expression (default value,
2036 etc) a reference to an incomplete type is legal: legality of

2038 object or subprogram) is frozen.
2040 2017-09-06 Gary Dismukes <dismukes@adacore.com>
2042 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

2053 * a-comlin.ads, a-comlin.adb (Argument): Simplify the code, now that
2054 we can use modern Ada in this package.
2055 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2056 Move Ada.Command_Line.Response_File to System.Response_File,
2057 and make Ada.Command_Line.Response_File into a rename of
2058 System.Response_File. This is to avoid having gnatbind depend
2059 Ada.Command_Line, which would damage the bootstrap process now
2060 that Ada.Command_Line contains modern Ada (the raise expression).
2061 * gnatbind.adb: Avoid dependence on
2062 Ada.Command_Line. Depend on System.Response_File instead
2063 of Ada.Command_Line.Response_File. Change one call to
2064 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2065 to Ada.Command_Line.Argument_Count to use Arg_Count.
2066 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
2068 2017-09-06 Bob Duff <duff@adacore.com>
2070 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

2202 (except for those that are renamings of parent discriminants)
2203 to produce additional assignments for the discriminants of the
2204 left-hand side, which are invisible in the righ-hand side and
2205 not retrievable as selected components.
2207 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2209 * sem_util.adb (Needs_One_Formal): The first formal of such a

2248 constraint for it, given that the constrained discriminants are
2249 not visible in the object.
2250 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2251 side may be derived from that of the left-hand side (as in the
2252 case of an assignment with a change of representation) so the
2253 discriminant to be used in the retrieval of the value of the
2254 component must be the entity in the type of the right-hand side.

2283 in a set membership is an overloaded enumeration literal, and
2284 the type of the alternative is resolved from a previous one,
2285 replace the entity of the alternative as well as the type,
2286 to prevent inconsistencies between the entity and the type.

2829 * exp_ch6.adb (Expand_Call_Helper): When locating the
2830 accessibility entity created for an access parameter, handle
2831 properly a reference to a formal of an enclosing subprogram. if
2832 the reference appears in an inherited class-wide condition, it
2833 is the rewriting of the reference in the ancestor expression,
2834 but the accessibility entity must be that of the current formal.
2836 2017-05-02 Javier Miranda <miranda@adacore.com>
2838 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.
2839 (Expand_N_Op_Add, Expand_N_Op_Divide, Expand_N_Op_Minus,

2873 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
2874 procedure body for a local (sub)type declaration within a
2875 predicate function. Invariant checks do not apply to these, and
2876 the expansion of the procedure will happen in the wrong scope,
2877 leading to misplaced freeze nodes.
2879 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2881 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2882 to analyze generated actions. If the main unit is a body,

2887 * einfo.adb (Declaration_Node): flip branches of
2888 an IF statement to avoid repeated negations in its condition;

2918 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2919 Refine predicate for the case where the primitive operation
2920 is a renaming of equality. An overriding operation that is
2921 a user-defined renaming of predefined equality inherits its
2922 slot from the overridden operation. Otherwise it is treated
2923 as a predefined op and occupies the same predefined slot as
2924 equality. A call to it is transformed into a call to its alias,
2925 which is the predefined equality. A dispatching call thus uses
2926 the proper slot if operation is further inherited and called
2927 with class-wide arguments.
2929 2017-05-02 Justin Squirek <squirek@adacore.com>
2931 * errout.adb (Set_Msg_Text): Add a case to switch the message
2932 type when the character '[' is detected signifying a warning
2933 about a run-time exception.
2934 * opt.ads Add a new Warning_Mode value for new switch
2935 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
2936 to handle new warning mode

2940 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2942 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
2943 declaration that operates on some fixed point type.

2962 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2964 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2965 statement if the initialization call is a null procedure, as
2966 can happen with a controlled type with no explicit Initialize
2967 procedure, or an array of such.
2968 * exp_ch7.adb (Process_Object_Declaration): For a type with
2969 controlled components that has a trivial Initialize procedure,
2970 insert declaration for finalization counter after object

2973 finalization block and attendant declarations if component has
2974 a trivial Initialize procedure.
2975 (Make_Init_Call): Do not generate a call if controlled type has
2976 a trivial Initialize procedure.
2978 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
2980 * g-forstr.ads (Data): Move Format component last.
2981 * g-forstr.adb ("+"): Adjust for above change.

3004 * einfo.ads (Is_Class_Wide_Clone): Likewise.
3006 2017-05-02 Gary Dismukes <dismukes@adacore.com>
3008 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
3009 parameter Array_Comp to indicate the case of an array object
3010 with null-excluding components.
3011 * checks.adb (Null_Exclusion_Static_Checks):
3012 Call Compile_Time_Constraint_Error instead of
3013 Apply_Compile_Time_Constraint_Error in the component case. Also
3014 call that when Array_Comp is True, with an appropriate warning for
3015 the array component case. Only create an explicit initialization
3016 by null in the case of an object of a null-excluding access type
3017 (and no longer do that in the component case).
3018 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3019 Array_Comp defaulted to False. Pass Empty for the Comp
3020 actual when calling Null_Exclusion_Static_Checks in the case
3021 where Comp_Decl matches Object_Decl, because we don't have a
3022 component in that case. In the case of an object or component
3023 of an array type, pass True for Array_Comp on the recursive call

3028 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3029 compute the linux priority from the Ada priority. Call this everywhere
3030 required. In particular, the previous version was not doing this
3031 computation when setting the ceiling priority in various places. It
3032 was just converting to C.int, which results in a ceiling that is off
3035 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3037 * sem_ch3.adb: Comment predicate inheritance.
3039 2017-05-02 Tristan Gingold <gingold@adacore.com>

3054 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3055 here from exp_ch9, to recognize objects whose creation requires
3056 dynamic allocation, so that the proper warning can be emitted
3057 when restriction No_Implicit_Heap_Allocation is in effect.
3058 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size

3066 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3068 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
3069 visibility rules for equality operators that apply within an
3070 instantiation apply within an inlined body.
3071 * sem_type.adb (Add_One_Interp): ditto.
3073 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>

3081 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
3082 Name_No_Tagged_Streams): Move to regular pragmas. Add
3083 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
3084 and Secondary_Stack_Size.

3086 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
3087 Pragma_No_Tagged_Streams to second part.

3108 a discriminant check when the associated type is a constrained
3109 subtype created for an unconstrained nominal type.
3110 * exp_attr.adb: Minor reformatting.
3112 2017-05-02 Bob Duff <duff@adacore.com>

3125 (Expand_SPARK): Call new
3126 function to expand operator /=.
3128 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3130 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3131 Simplify the expression for a fixed-fixed division to remove
3132 divisions by constants whenever possible, as an optimization
3133 for restricted targets.

3137 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3139 2017-05-02 Bob Duff <duff@adacore.com>
3141 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3142 to find primitive ops, instead of using an Identifier that will
3143 later be looked up. This is necessary because these ops are not
3144 necessarily visible at all places where we need to call them.
3145 * exp_util.ads: Minor comment fix.
3147 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3149 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3150 references are fully conformant if they are both expansions
3151 of the discriminant of a protected type, within one of the
3152 protected operations. One occurrence may be expanded into a
3153 constant declaration while the other is an input parameter to
3154 the corresponding generated subprogram.

3158 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3159 recursivly searching composite-types for null-excluding access
3160 types and verifying them.
3161 (Analyze_Object_Declaration): Add a
3162 call to Check_Null_Excluding_Components for static verification
3163 of non-initialized objects.
3164 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3165 a parameter for a composite-type's component and an extra case
3166 for printing component information.

3177 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
3178 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
3179 clauses from the runtime.
3181 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3183 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
3184 array components specially.
3186 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3188 * sem_ch8.adb (Premature_Usage): If the premature usage of
3189 an entity is as the expression in its own object decaration,
3190 rewrite the reference as Any_Id to prevent cascaded errors or
3191 compiler loops when such an entity is used in an address clause.
3193 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3195 * gcc-interface/decl.c (components_to_record): Add missing guard.

3200 Put back pending fields onto the regular list if the misalignment
3201 happens to cancel itself.
3203 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3205 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3206 controlling actual in a prefixed call, preserve the original node
3207 information if the prefix itself has been rewritten, for ASIS use.
3209 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3211 * exp_ch6.adb (Insert_Post_Call_Actions):
3212 Code clean up. Insert the post-call actions after an enclosing
3213 procedure call when N denotes a function call and appears as an
3214 actual parameter in the procedure call.
3216 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3218 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3219 for the component, also reject the attribute if the component
3220 doesn't end on a byte boundary and its scalar storage order is
3221 different from that of the enclosing record type.
3223 2017-04-28 Javier Miranda <miranda@adacore.com>
3225 * atree.ads (Info_Messages): Removed.
3226 (Warning_Info_Messages): New counter.

3255 2017-04-28 Bob Duff <duff@adacore.com>
3257 * sem_util.ads, sem_util.adb (Might_Raise): New function
3258 that replaces Is_Exception_Safe, but has the opposite
3259 sense. Is_Exception_Safe was missing various cases -- calls inside
3260 a pragma Debug, calls inside an 'if' or assignment statement,
3261 etc. Might_Raise now walks the entire subtree looking for things
3263 * exp_ch9.adb (Is_Exception_Safe): Remove.
3264 (Build_Protected_Subprogram_Body): Replace call to
3265 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3266 constants where possible).
3267 * exp_ch7.adb: Rename Is_Protected_Body -->
3268 Is_Protected_Subp_Body. A protected_body is something different
3271 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3273 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.

3295 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3297 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3298 Interrupt_Handler and Attach_Handler): Generate reference
3299 to protected operation to prevent spurious warnings about
3300 unreferenced entities. Previous scheme failed with style checks
3303 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3305 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3306 that follows an expression function must not be relocated to
3307 the generated body, because it applies to the code that follows.
3309 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3311 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3312 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3313 code that might violate the more stringent checking for 'Access
3314 introduced in Ada 2005.
3316 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3318 * a-cforse.adb: minor style fix in comment.
3320 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3322 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3323 initialize Block_Decls variable.
3324 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3325 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
3326 * exp_disp.adb (Expand_Interface_Actuals): Initialize
3327 Formal_DDT and Actual_DDT variables.

3334 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3336 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3338 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3339 node between access types, freeze the designated type as well,
3340 so that dispatch table pointers are created in the proper scope,
3341 and not in the constructed body of the expression function.
3343 2017-04-28 Bob Duff <duff@adacore.com>
3345 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3346 value makes large compilations faster, but small compilations slower.
3348 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3350 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3352 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3354 * erroutc.adb (Compilation_Errors): Do not consider info messages
3355 as suitable warnings when warnings must be treated as errors.
3356 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3357 internally-generated packages when outputting completion
3359 * errout.adb (Output_Messages): Do not consider info messages as

3362 suitable warnings when warnings must be treated as errors.
3364 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3366 * warnsw.ads: Minor fix for incorrect wording in comment.
3368 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3370 * sem_res.adb (In_Instance_Code): New predicate in
3371 Valid_Conversion, to determine whether a type conversion appears
3372 as (or within) an actual for a formal object. Type conversions
3373 in instances are not rechecked in Valid_Conversion because
3374 visibility changes between generic location andi instance may
3375 lead to spurious errors, but conversions within an actual must be
3376 fully checked, and they are not fully resolved when pre-analyzing
3379 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3381 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3382 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3383 of the relocated node will have mangled Parent pointers.
3384 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3385 tables used in conjunction with entity and itype replication.
3386 (Visit_Entity): Rewrite the restriction on which entities
3387 require duplication. The restriction now includes all types.
3389 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3391 * a-cofuse.ads, a-cfdlli.ads, a-cfhase.adb, a-cfhase.ads, a-cfinve.adb,

3405 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3407 * sem_ch4.adb: Fix copy/pasto.
3409 2017-04-27 Tristan Gingold <gingold@adacore.com>
3411 * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
3412 raise-gcc.c. Fix include search path for raise-gcc.c
3414 2017-04-27 Eric Botcazou <ebotcazou@adacore.com>
3416 * fe.h (Warn_On_Questionable_Layout): Declare.
3417 * warnsw.ads (Warn_On_Record_Holes): Move down.

3419 (Warning_Record): Add Warn_On_Questionable_Layout field.
3420 * warnsw.adb (All_Warnings): Set Warn_On_Questionable_Layout.
3421 (Restore_Warnings): Likewise.
3422 (Save_Warnings): Likewise.
3423 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3424 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3425 components_to_record.
3426 (gnu_field_to_gnat): New function.
3427 (warn_on_field_placement): Likewise.
3428 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3429 parameters. Rename local variables and adjust recursive call.
3430 Rework final scan of the field list and implement warnings on the
3431 problematic placement of specific sorts of fields.
3433 2017-04-27 Bob Duff <duff@adacore.com>
3435 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

3439 * sem_ch4.adb, sem_ch6.adb, sem_ch8.adb, sem_ch9.adb, sem_elab.adb,
3440 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3441 For efficiency, cache results of Is_Internal_File_Name and
3442 Is_Predefined_File_Name in the Units table. This avoids a lot
3443 of repeated text processing.
3445 2017-04-27 Emmanuel Briot <briot@adacore.com>
3447 * g-comlin.adb (Sort_Sections): remove useless test.
3449 2017-04-27 Claire Dross <dross@adacore.com>
3451 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3452 allow the use of regular equality over elements in contracts.
3453 (Formal_Model): Ghost package containing model functions that are
3454 used in subprogram contracts.
3455 (Current_To_Last): Removed, model functions should be used instead.
3456 (First_To_Previous): Removed, model functions should be used instead.
3457 (Strict_Equal): Removed, model functions should be used instead.
3458 (No_Overlap): Removed, model functions should be used instead.
3459 (Equivalent_Keys): Functions over cursors are removed. They were
3460 awkward with explicit container parameters.
3461 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3462 allow the use of regular equality over elements in contracts.
3463 (Formal_Model): Ghost package containing model functions that
3464 are used in subprogram contracts.
3465 (Current_To_Last): Removed, model functions should be used instead.
3466 (First_To_Previous): Removed, model functions should be used instead.
3467 (Strict_Equal): Removed, model functions should be used instead.
3468 (No_Overlap): Removed, model functions should be used instead.
3470 2017-04-27 Yannick Moy <moy@adacore.com>
3472 * gnat1drv.adb: Code cleanup.
3474 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3476 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3477 attribute reference in a post- condition is the subprogram to
3478 which the condition applies. If the condition is inherited
3479 by a type extension, the prefix becomes a reference to the
3480 inherited operation, but there is no need to create a wrapper
3481 for this operation, because 'Result is expanded independently
3482 when elaborating the postconditions.
3484 2017-04-27 Bob Duff <duff@adacore.com>
3486 * sinput.adb: Minor code cleanup.
3487 * namet.adb (Append): Create faster versions of
3488 Append(String) and Append(Name_Id) by using slice assignment
3490 * sem_util.adb (In_Instance): Speed this up by removing
3491 unnecessary tests; Is_Generic_Instance is defined for all
3493 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3494 Remove unused function.
3495 * alloc.ads (Nodes_Initial): Use a much larger value, because
3496 the compiler was spending a lot of time copying the nodes table
3497 when it grows. This number was chosen in 1996, so is rather out
3498 of date with current memory sizes. Anyway, it's virtual memory.
3499 Get rid of Orig_Nodes_...; use Node_... instead.
3500 * atree.adb (Lock): Do not release the Nodes tables; it's a
3502 Orig_Nodes_ ==> Nodes_
3503 * nlists.adb: Orig_Nodes_ ==> Nodes_
3504 * g-table.adb: Remove unused "with" clause.
3505 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3506 not be used by clients.
3507 * g-dyntab.adb (Last_Allocated): New function
3508 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3510 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3512 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3514 (Subtypes_Statically_Match): Remove duplicate check.
3515 * sem_prag.adb (Check_Arg_Is_External_Name): Remove duplicate check.
3517 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3519 * exp_aggr.adb (Replace_Type): Remove the special processing
3520 for selected components.

3531 for qualified expressions, type conversions, and unchecked
3533 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
3534 processing for Ada 83 and instances.
3535 (Object_Access_Level): Merge the processing for indexed components
3536 and selected components.
3537 * uname.adb (Add_Node_Name): Merge the processing for stubs.
3539 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3541 * checks.adb (Install_Primitive_Elaboration_Check):

3545 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3547 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
3548 of Expand_Dispatching_Call. If the denoted subprogram has a
3549 class-wide precondition, this is the only precondition that

4065 * exp_ch4.adb (Insert_Dereference_Action):
4066 Do not adjust the address of a controlled object when the
4067 associated access type is subject to pragma No_Heap_Finalization.
4070 2017-04-27 Pierre-Marie de Rodat <derodat@adacore.com>

4073 TYPE_ARTIFICIAL on created types.
4075 2017-04-27 Claire Dross <dross@adacore.com>
4077 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
4078 modifications in functional containers.
4079 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4080 to improve readablity. Subprograms are separated between basic
4081 operations, constructors and properties. Universally quantified
4082 formulas in contracts are factorized in independant functions
4083 with a name and a comment. Names of parameters are improved.
4085 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4087 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4089 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4091 * sem_res.adb (Resolve_Type_Conversion): Do not
4092 install a predicate check here since this is already done during
4093 the expansion phase. Verify whether the operand satisfies the
4094 static predicate (if any) of the target type.
4095 * sem_ch3.adb (Analyze_Object_Declaration): Do
4096 not install a predicate check if the object is initialized by
4097 means of a type conversion because the conversion is subjected

4121 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
4122 in gnat1 and gnatbind.
4123 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4124 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4132 modifications in functional containers.
4133 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4134 to improve readablity. Subprograms are separated between basic
4135 operations, constructors and properties. Universally quantified
4136 formulas in contracts are factorized in independant functions
4137 with a name and a comment. Names of parameters are improved.

4168 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
4171 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4173 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4174 the loop which detects potential enclosing transient scopes. The
4175 loop now terminates much earlier as transient scopes are bounded
4176 by packages and subprograms.
4178 2017-04-27 Claire Dross <dross@adacore.com>
4180 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4181 allow the use of regular equality over elements in contracts.
4182 (Cursor): Type is now public so that it can be used in
4184 (Formal_Model): Ghost package containing
4185 model functions that are used in subprogram contracts.
4186 (Current_To_Last): Removed, model functions should be used
4188 (First_To_Previous): Removed, model functions should
4190 (Strict_Equal): Removed, model functions
4191 should be used instead.
4192 (Append): Default parameter value
4193 replaced by new wrapper to allow more precise contracts.
4194 (Insert): Default parameter value replaced by new wrapper to
4195 allow more precise contracts.
4196 (Delete): Default parameter
4197 value replaced by new wrapper to allow more precise contracts.
4198 (Prepend): Default parameter value replaced by new wrapper to
4199 allow more precise contracts.

4211 Default_Initial_Condition procedure of a type under the SPARK
4212 elaboration checks umbrella.
4214 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

4223 * adaint.c (__gnat_get_current_dir): Return 0 in length if
4225 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
4226 exception if getcwd failed.

4231 entities with special prefix.
4233 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4235 * debug.adb Change the documentation of switch -gnatd.s.
4236 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4237 to manage the secondary stack when an enclosing scope already
4238 performs this functionality (aka relaxed management). Switch
4239 -gnatd.s may be used to force strict management in which case
4240 the block will manage the secondary stack unconditionally. Add
4241 a guard to stop the traversal when encountering a package or a
4244 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4246 * sem_res.adb (Resolve_Call): Refine further the handling of
4247 limited views of return types in function calls. If the function
4248 that returns a limited view appears in the current unit,
4249 we do not replace its type by the non-limited view because
4250 this transformation is performed int the back-end. However,
4251 the type of the call itself must be the non-limited view, to
4252 prevent spurious resolution errors.
4254 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4256 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4257 Removed, proposed implementation using generics for class-wide
4258 preconditions proved impractical.
4259 (Class_Wide_Clone): New attribute of subprogram. Designates
4260 subprogram created for primitive operations with class-wide
4261 pre/postconditions that contain calls to other primitives. The
4262 clone holds the body of the original primitive, but the
4263 pre/postonditions do not apply to it. The original body is
4264 rewritten as a wrapper for a call to the clone.
4265 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4266 the flag is set, no code for the corresponding pre/postconditions
4267 is inserted into its body.
4269 2017-04-27 Bob Duff <duff@adacore.com>
4271 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
4272 Scalar_Storage_Order if -gnatI is given.
4273 * sem_prag.adb (Analyze_Pragma): Ignore
4274 Default_Scalar_Storage_Order if -gnatI is given.

4279 the position where the element should be inserted.
4280 (Remove): New function that removes an element from the container.
4281 * a-cofuma.ads (Add): Adapt to the new API of Base.Add.
4282 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
4283 (Remove): New function that removes an element from a set.
4284 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
4285 (Remove): New function that removes an element from a sequence.
4286 (Insert): New function that adds anywhere in a sequence.

4296 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4298 * lib-xref.adb (Generate_Reference): The use
4299 of attribute 'Result is not considered a violation of pragma
4302 2017-04-27 Justin Squirek <squirek@adacore.com>
4304 * cstand.adb (Create_Standard): Correctly set
4305 Directly_Designated_Type for Any_Access.
4306 * sem_type.adb (Covers): Minor grammar fixes.
4308 2017-04-27 Bob Duff <duff@adacore.com>

4315 private child of Ada.Containers used to implement all functional
4317 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4318 child of Ada.Containers. It provides functional indefinite unbounded
4319 maps which can be used as high level models for specification
4321 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4322 child of Ada.Containers. It provides functional indefinite unbounded
4323 sets which can be used as high level models for specification
4325 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4326 child of Ada.Containers. It provides functional indefinite unbounded
4327 vectors which can be used as high level models for specification
4329 * Makefile.rtl: Add new packages.
4330 * impunit.adb: Add new packages.
4332 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4334 * sem_ch4.adb: Minor reformatting.
4336 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4338 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4339 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4340 point type actual that has user-defined arithmetic primitives,
4341 when there is a previous actual for a formal package that defines
4342 a fixed-point type with the parent user-defined operator.
4344 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4346 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4347 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4348 the component type allows range checks.
4350 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4352 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4353 corresponding declaration, because formal derived types are
4354 rewritten as private extensions.
4356 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4358 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4359 dimensions of operands if node has been analyzed already, because
4360 previous analysis and dimension checking will have removed the
4361 dimension information from the operands.
4363 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4365 * debug.adb: Document the use of switch -gnatd.s.
4366 * einfo.ads Update the documentation on attribute
4367 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4368 the uses of these attributes from certain entities.
4369 * exp_ch7.adb (Make_Transient_Block): Reimplement the circuitry
4370 which determines whether the block should continue to manage
4371 the secondary stack.
4372 (Manages_Sec_Stack): New routine.
4374 2017-04-27 Bob Duff <duff@adacore.com>

4381 a section on SPARK mode. Update the placement of section on
4382 expression functions.
4384 2017-04-27 Bob Duff <duff@adacore.com>
4386 * sinput.adb (Get_Source_File_Index): Don't

4420 generating C code on complex case expressions.
4422 2017-04-25 Arnaud Charlet <charlet@adacore.com>
4424 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
4425 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4426 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4427 Ada_2012 instead of Ada_2005 to be compatible with the above
4429 * bindgen.adb: Silence new warning on pragma Ada_95.
4431 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4433 * checks.adb (Generate_Range_Check): Revert part of previous change.
4435 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4439 parameter association in a procedure call.
4441 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
4443 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4444 Fix spelling mistakes.
4446 2017-04-25 Bob Duff <duff@adacore.com>
4448 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4449 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4450 for source buffers. Fix misc obscure bugs.
4451 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4452 checking, for source buffers. Modify representation clause for
4453 Source_File_Record as appropriate. Move Source_File_Index_Table
4454 from spec to body, because it is not used outside the body.
4455 Move Set_Source_File_Index_Table into the private part, because
4456 it is used only in the body and in children. Use trickery to
4457 modify the dope in the generic instantiation case. It's ugly,
4458 but not as ugly as the previous method. Fix documentation.
4459 Remove obsolete code.
4460 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
4461 indexing in source buffers.

4475 expander is not active or when index/range checks are suppressed
4477 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4478 Remove variants that include a Supress parameter. These routines
4479 are never used, and were introduced before the current scope-based
4480 check suppression method.
4482 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

4499 (Known_Non_Null): Moved from Exp_Util. Most of the logic in
4500 this routine is now carried out by Null_Status.
4501 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
4502 is now carried out by Null_Status.
4503 (Null_Status): New routine.

4510 error on the return type of an expression function that is a
4511 completion, if the type is derived from a generic formal type.
4513 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4530 errout.adb, sinput.adb, sinput.ads, cstand.adb, scn.adb,
4531 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4532 the Internal_Source buffer. This removes the incorrect call to "="
4533 the customer noticed.
4534 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4535 eventually need to eliminate them altogether. Or else get rid
4536 of zero-origin addressing.
4538 2017-04-25 Claire Dross <dross@adacore.com>
4540 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New

5069 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5070 (10-15): if derived type T with progenitors is abstract,
5071 and primitive P of this type inherits non-trivial classwide
5072 preconditions from both a parent operation and from an interface
5073 operation, then the inherited operation is abstract if the parent
5074 operation is not null.
5075 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5076 with Covered_Interface_Op to yield the actual interface operation
5077 that is implemented by a given inherited operation.
5079 2017-04-25 Javier Miranda <miranda@adacore.com>
5081 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
5082 and right operands after performing the validity checks. Required
5083 because validity checks may remove side effects from the operands.
5085 2017-04-25 Javier Miranda <miranda@adacore.com>
5087 * exp_attr.adb (Attribute_Unrestricted_Access):
5088 Do not disable implicit type conversion. Required to generate
5089 code that displaces the pointer to reference the secondary

5100 values, and comparing them must use Expr_Value_S.
5102 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5104 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5105 dereference is introduced for the object, and the object is
5106 overloaded, do not check whether it is aliased, because it may
5107 include an implicit dereference.
5108 * sem_type.adb (Disambiguate): If two interpretations are access
5109 attribute types with the same designated type keep either of
5110 them and do not report an ambiguity. A true ambiguity will be
5113 2017-04-25 Bob Duff <duff@adacore.com>
5115 * a-numeri.ads: Change the encoding of Greek letter Pi from
5116 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5117 to indicate the encoding. We considered using a byte order mark
5118 (BOM), but that causes various trouble (misc software eats the
5119 BOM, if you have a patch with a BOM, then it's not at the start
5120 of the patch, so it's not a BOM, the BOM affects with-ing files,
5122 * scng.adb, s-wchcnv.adb: Minor.

5158 restrictions when the handler is internally generated and the
5161 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5163 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
5164 enforce legality rule on classwide preconditions inherited from
5165 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5166 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5167 subprogram need not be dispatching if it appears in a precondition
5168 for an abstract or null subprogram.
5170 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5172 * sem_ch10.adb: Minor typo fix.
5174 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5176 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
5178 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5180 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
5181 have a length which is a power of 2.
5182 (Is_Predefined_File_Name): Likewise. Adjust comment.
5184 2017-04-25 Bob Duff <duff@adacore.com>
5186 * exp_aggr.adb (Component_Count): Protect the
5187 arithmetic from attempting to convert a value >= 2**31 to Int,
5188 which would otherwise raise Constraint_Error.
5190 2017-04-25 Bob Duff <duff@adacore.com>
5192 * opt.ads (Locking_Policy): Fix incorrect documentation. The
5193 first character of the policy name is not unique.
5195 2017-04-25 Bob Duff <duff@adacore.com>
5197 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
5198 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
5199 about this flag not being used. It was already used, and it is

5216 Save and restore the value of global flag
5217 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
5218 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
5219 the corresponding spec or the body must ignore all SPARK_Mode
5220 pragmas found within.
5221 (Analyze_Subprogram_Declaration): Mark
5222 the spec when it needs to ignore all SPARK_Mode pragmas found
5223 within to allow the body to infer this property in case it is
5224 instantiated or inlined later.
5225 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5226 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5227 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5228 when the corresponding spec also ignored all SPARK_Mode pragmas
5230 (Analyze_Package_Declaration): Mark the spec when
5231 it needs to ignore all SPARK_Mode pragmas found within to allow
5232 the body to infer this property in case it is instantiated or
5234 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
5235 Save and restore the value of flag
5236 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5237 formal spec when it needs to ignore all SPARK_Mode
5238 pragmas found within to allow the body to infer this
5239 property in case it is instantiated or inlined later.
5240 (Analyze_Package_Instantiation): Save and restore the value
5241 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
5242 the instance spec when it needs to ignore all SPARK_Mode
5243 pragmas found within to allow the body to infer this
5244 property in case it is instantiated or inlined later.

5246 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5247 instance spec and anonymous package when they need to ignore
5248 all SPARK_Mode pragmas found within to allow the body to infer
5249 this property in case it is instantiated or inlined later.
5250 (Instantiate_Package_Body): Save and restore the value of global
5251 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

5260 * sem_prag.adb (Analyze_Pragma): Update the reference to
5261 Ignore_Pragma_SPARK_Mode.
5262 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5263 all SPARK_Mode pragmas defined within yields mode "off".
5265 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5267 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

5284 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5286 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5287 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5288 variable and set it to True whenever the main hash table is
5289 populated. Short- circuit the Assoc function if it is false
5290 and add associated guards.
5292 2017-04-25 Olivier Hainque <hainque@adacore.com>
5294 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5295 specs without elaboration code that have an elaboration counter
5296 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5297 * sem_ch10.adb (Analyze_Compilation_Unit):
5298 Set_Elaboration_Entity_Required when requested to preserve
5299 control flow, to ensure the unit elaboration is materialized at
5300 bind time, resulting in the inclusion of the unit object file
5301 in the executable closure at link time.
5303 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5305 * exp_dbug.adb: In Debug_Renaming_Declaration,
5306 when dealing with indexed component, accept to produce a renaming
5307 symbol when the index is an IN parameter or when it is a name
5308 defined in an outer scope.
5310 2017-04-25 Yannick Moy <moy@adacore.com>
5312 * errout.adb (Error_Msg): Adapt continuation
5313 message in instantiations and inlined bodies for info messages.
5315 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5317 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5318 Use direct 4-character slice comparisons.
5320 pragma Inline. (Has_Suffix): Delete.
5321 (Is_Internal_File_Name):
5322 Test Is_Predefined_File_Name first.
5323 (Is_Predefined_File_Name):
5324 Use direct slice comparisons as much as possible and limit all
5325 comparisons to at most 8 characters.
5327 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5329 * checks.adb (Insert_Valid_Check): Code cleanup.
5330 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5331 (Expand_Actuals): Generate proper copy-back for a validation
5332 variable when it acts as the argument of a type conversion.
5333 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5334 predicate to operate on type qualifications.
5336 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5338 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5341 2017-04-25 Bob Duff <duff@adacore.com>
5343 * sem_prag.adb (No_Return): Give an error if the pragma applies
5344 to a body. Specialize the error for the specless body case,
5345 as is done for (e.g.) pragma Convention.
5346 * debug.adb: Add switch -gnatd.J to disable the above legality
5347 checks. This is mainly for use in our test suite, to avoid
5348 rewriting a lot of illegal (but working) code. It might also
5349 be useful to customers. Under this switch, if a pragma No_Return
5350 applies to a body, and the procedure raises an exception (as it
5351 should), the pragma has no effect. If the procedure does return,
5352 execution is erroneous.
5354 2017-04-25 Bob Duff <duff@adacore.com>
5356 * exp_ch6.adb (Expand_Actuals): This is the
5357 root of the problem. It took N as an 'in out' parameter, and in
5358 some cases, rewrote N, but then set N to Original_Node(N). So
5359 the node returned in N had no Parent. The caller continued
5360 processing of this orphaned node. In some cases that caused a
5361 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5362 and trips over the Empty Parent). The solution is to make N an
5363 'in' parameter. Instead of rewriting it, return the list of
5364 post-call actions, so the caller can do the rewriting later,
5365 after N has been fully processed.
5366 (Expand_Call_Helper): Move most of Expand_Call here. It has
5367 too many premature 'return' statements, and we want to do the
5368 rewriting on return.
5369 (Insert_Post_Call_Actions): New procedure to insert the post-call
5370 actions in the appropriate place. In the problematic case,
5371 that involves rewriting N as an Expression_With_Actions.
5372 (Expand_Call): Call the new procedures Expand_Call_Helper and
5373 Insert_Post_Call_Actions.
5375 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5377 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5378 properly type derived from generic formal types, to handle
5379 properly modified version of ACATS 4.1B B611017.
5381 2017-04-25 Javier Miranda <miranda@adacore.com>
5383 * exp_unst.adb (Subp_Index): Adding missing
5384 support for renamings and functions that return a constrained
5385 array type (i.e. functions for which the frontend built a
5386 procedure with an extra out parameter).
5388 2017-04-25 Pascal Obry <obry@adacore.com>
5390 * s-string.adb: Minor code clean-up.
5392 2017-04-25 Bob Duff <duff@adacore.com>

5397 function for Non_Blocking_Wait_Process.
5399 2017-04-25 Bob Duff <duff@adacore.com>
5401 * prep.adb (Preprocess): Remove incorrect
5402 Assert. Current character can be ASCII.CR.
5404 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5406 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5407 convention Stdcall, which has a number of exceptions. Convention
5408 is legal on a component declaration whose type is an anonymous
5409 access to subprogram.
5411 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5413 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5414 (Try_One_Prefix_Interpretation): Use the base type when dealing
5415 with a subtype created for purposes of constraining a private
5416 type with discriminants.
5418 2017-04-25 Javier Miranda <miranda@adacore.com>
5420 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
5421 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
5422 dispatching primitives (Restore_Warnings): Restore warning on
5423 late dispatching primitives (Save_Warnings): Save warning on late
5424 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5425 to enable/disable this warning.
5426 (WA_Warnings): Set warning on late dispatching primitives.
5427 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5428 that its parent type has a private extension.
5429 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5431 * usage.adb: Document -gnatw.j and -gnatw.J.
5433 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5435 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5438 2017-04-25 Bob Duff <duff@adacore.com>
5440 * binde.adb (Validate): Do not pass dynamic strings
5441 to pragma Assert, because older compilers do not support that.
5443 2017-04-25 Bob Duff <duff@adacore.com>
5445 * s-fileio.adb (Close): When a temp file is
5446 closed, delete it and clean up its Temp_File_Record immediately,
5447 rather than waiting until later.
5448 (Temp_File_Record): Add File
5449 component, so Close can know which Temp_File_Record corresponds
5450 to the file being closed.
5451 (Delete): Don't delete temp files,
5452 because they are deleted by Close.
5453 (Open): Set the File component
5454 of Temp_File_Record. This requires moving the creation of the
5455 Temp_File_Record to the end, after the AFCB has been created.
5457 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5459 * checks.adb (Insert_Valid_Check): Do not generate
5460 a validity check when inside a generic.

5474 concerning inheritance of class-wide preconditions do not apply
5477 2017-04-25 Bob Duff <duff@adacore.com>
5479 * s-ficobl.ads: Minor comment fix.
5481 2017-04-25 Yannick Moy <moy@adacore.com>
5483 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5484 conversions from float to integer in GNATprove mode.
5485 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5486 to call Apply_Type_Conversion_Checks, so that range checks
5487 are properly positioned when needed on conversions, including
5488 when converting from float to integer. (Determine_Range): In
5489 GNATprove mode, take into account the possibility of conversion
5490 from float to integer.
5491 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5492 check on conversions from fixed-point to integer, not anymore
5493 on conversions from floating-point to integer, when in GNATprove
5496 2017-04-25 Yannick Moy <moy@adacore.com>
5498 * checks.adb (Determine_Range_R): Special case type conversions
5499 from integer to float in order to get bounds in that case too.
5500 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5501 mode, for computations involved in interval checking.

5515 * exp_attr.adb (Make_Range_Test): Add processing for validation
5516 variables to avoid extra reads and copies of the prefix.
5517 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5518 variables in order to reflect any changes done in the variable
5519 back into the original object.
5520 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5521 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5527 generate Finalize_Address routines for CodePeer.
5529 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5531 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5532 Analyze_Pre_Post_Condition, to implement the legality checks
5533 mandated by AI12-0131: Pre'Class shall not be specified for an
5534 overriding primitive subprogram of a tagged type T unless the
5535 Pre'Class aspect is specified for the corresponding primitive
5536 subprogram of some ancestor of T.
5538 2017-04-25 Bob Duff <duff@adacore.com>
5540 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5541 is redundant, set its Used_Operations to empty. This is only
5542 necessary for use clauses that appear in the parent of a generic
5543 child unit, because those use clauses get reanalyzed when we
5544 instantiate the generic, and we don't want the Used_Operations
5545 carried over from the original context (where it was probably
5548 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5550 * exp_ch6.adb: Minor reformatting.

5561 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5563 * sem_ch8.adb (Find_Type): For an attribute reference
5564 'Class, if prefix type is synchronized and previous errors
5565 have suppressed the creation of the corresponding record type,

5571 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5572 is True, then don't generate the accessibility check for the
5573 tag of a tagged result.
5574 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
5575 if CodePeer_Mode is True, then don't generate the
5576 tag checks for the result of call to an instance of
5577 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5578 descendant of" check and the accessibility check).

5588 * exp_ch4.adb (Library_Level_Target): New function.
5589 (Expand_Concatenate): When optimization is enabled, also expand
5590 the operation out-of-line if the concatenation is present within
5591 the expression of the declaration of a library-level object and
5592 not only if it is the expression of the declaration.
5594 2017-04-25 Bob Duff <duff@adacore.com>
5596 * freeze.adb (Freeze_Object_Declaration): Do
5597 not Remove_Side_Effects if there is a pragma Linker_Section,
5598 because in that case we want static initialization in the
5599 appropriate section.
5601 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5603 * exp_dbug.adb: Minor rewording and reformatting.
5605 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5607 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5608 handle the proposed changes to rules concerning potentially
5609 unevaluated expressions, to include selected components that
5610 do not depend on discriminants, and indexed components with
5612 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5613 predicate in quantified expression, and fix bugs in the handling
5614 of case expressions and membership test.

5618 2017-04-25 Bob Duff <duff@adacore.com>
5620 * s-secsta.adb (SS_Info): Add a comment
5621 explaining why we don't need to walk all the chunks in order to
5622 compute the total size.
5624 2017-04-25 Bob Duff <duff@adacore.com>
5626 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length

5632 renaming entity for debug information, mark the entity as needing debug
5633 info if it comes from sources.
5635 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5637 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
5638 restriction converning the use of 'Address where the prefix is
5639 of a controlled type.
5641 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5643 * exp_dbug.adb: In Debug_Renaming_Declaration,
5644 skip slices that are made redundant by an indexed component

5652 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5654 * sem_ch3.adb (Check_Entry_Contract): Call
5655 Preanalyze_Spec_Expression so that resolution takes place as well.
5656 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5657 internal calls that appear in preconditions of protected
5658 operations, in default values for same, and in contract guards
5659 for contract cases in SPARK.
5661 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5663 * a-numaux.ads: Fix description of a-numaux-darwin
5665 (Double): Define to Long_Float.
5666 * a-numaux-vxworks.ads (Double): Likewise.
5667 * a-numaux-darwin.ads
5669 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
5670 * a-numaux-x86.ads: Fix package description.
5671 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5672 (Reduce): Adjust and complete description. Call Is_Nan instead of
5673 testing manually. Use an integer temporary to hold rounded value.
5674 * a-numaux-darwin.adb (Reduce): Likewise.
5675 (Is_Nan): New function.
5677 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5679 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5680 on analysis of prefix whose type is a current instance of a
5681 synchronized type, but where the prefix itself is an entity that
5684 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5686 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5687 the identity of callable entities therein, because they have been
5688 properly resolved, and prefixed calls may have been rewritten
5691 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5693 * exp_ch3.adb (Build_Init_Statements): Convert
5694 the expression of the pragma/aspect Secondary_Stack_Size to
5695 internal type System.Parameters.Size_Type before assigning
5696 it to the Secondary_Stack_Size component of the task type's
5697 corresponding record.

5707 * s-osinte-freebsd.ads: Minor comment tweaks
5709 2017-04-25 Javier Miranda <miranda@adacore.com>
5711 * urealp.adb (UR_Write): Reverse previous patch
5712 adding documentation on why we generate multiplications instead
5713 of divisions (needed to avoid expressions whose computation with
5714 large numbers may cause division by 0).
5716 2017-04-25 Bob Duff <duff@adacore.com>
5718 * erroutc.adb (Set_Specific_Warning_Off,
5719 Set_Warnings_Mode_Off): Use the correct source file for
5720 Stop. Was using Current_Source_File, which is only valid during
5721 parsing. Current_Source_File will have a leftover value from
5722 whatever file happened to be parsed last, because of a with_clause
5725 2017-04-25 Bob Duff <duff@adacore.com>
5727 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5728 to In_Predefined_Unit, but including GNAT units.
5729 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5730 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5731 because Should_Ignore_Pragma was not working reliably outside
5732 the parser, because Current_Source_File is not valid.
5733 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5734 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5771 Build_Invariant_Procedure_Body.
5772 (Build_Invariant_Procedure_Body):
5773 Remove refactored calls and integrated code from
5774 Add_Parent_Invariants and Add_Interface_Invariants.
5776 2017-04-25 Johannes Kanig <kanig@adacore.com>
5778 * errout.adb (Output_Messages): Adjust computation of total
5780 * erroutc.adb (Error_Msg): In statistics counts, deal
5781 correctly with informational messages that are not warnings.

5793 2017-04-25 Justin Squirek <squirek@adacore.com>
5795 * sem_ch3.adb (Analyze_Declarations): Minor
5796 correction to comments, move out large conditional and scope
5797 traversal into a predicate.
5798 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5801 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5803 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5804 of prefix whose type is a current instance of a synchronized
5805 type. If the prefix is an object this is an external call (or
5806 requeue) that can only access public operations of the object. The
5807 previous predicate was too restrictive, and did not allow public
5808 protected operations, only task entries.
5810 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5812 * sem_ch5.adb, fname.adb: Minor reformatting.
5814 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5816 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5817 * einfo.ads Update the placement of
5818 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5820 (Is_Anonymous_Access_Type): New routine.
5821 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5822 master for an access type subject to pragma No_Heap_Finalization.
5823 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5824 allocated or deallocated does not finalization actions if the
5825 associated access type is subject to pragma No_Heap_Finalization.
5826 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5827 * par-prag.adb Pragma No_Heap_Finalization does not need special
5828 processing from the parser.
5829 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5830 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5831 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5832 No_Heap_Finalization.
5833 (Analyze_Pragma): Add processing for
5834 pragma No_Heap_Finalization. Update various error messages to
5835 use Duplication_Error.
5836 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5837 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5838 and corresponding pragma id.
5840 2017-04-25 Bob Duff <duff@adacore.com>
5842 * freeze.adb (Freeze_Record_Type): Use the
5843 underlying type of the component type to determine whether it's
5844 elementary. For representation clause purposes, a private type
5845 should behave the same as its full type.
5846 * fname.ads, fname.adb (Is_Predefined_File_Name):
5847 Make sure things like "system.ali" are recognized as predefined.
5849 2017-04-25 Javier Miranda <miranda@adacore.com>
5851 * debug.adb: Update documentation of -gnatd.6.

5855 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5856 element iterator when the name is an overloaded function call,
5857 one of whose interpretations yields an array.
5859 2017-04-25 Bob Duff <duff@adacore.com>
5861 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5862 Is_Internal_Unit_Name): New functions for operating on unit
5863 names, as opposed to file names. There's some duplicated code
5864 with fname.adb, which is unfortunate, but it seems like we don't
5865 want to add dependencies here.
5866 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5867 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5868 is not a file name at all.
5869 * fname.ads, fname.adb: Document the fact that
5870 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5871 for ALI files, and fix the code so it works properly for ALI
5872 files. E.g. these should return True for "system.ali".
5874 2017-04-25 Justin Squirek <squirek@adacore.com>
5876 * exp_util.adb (Add_Invariant): Removed,
5877 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5878 and Add_Own_Invariant. (Add_Invariant_Check): Used
5879 for adding runtime checks from any kind of invariant.
5880 (Add_Inherited_Invariant): Generates invariant checks for
5881 class-wide invariants (Add_Interface_Invariants): Removed, code
5882 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5883 Create a types own invariant procedure (Add_Parent_Invariants):
5884 Removed, code moved to Build_Invariant_Procedure_Body
5885 (Build_Invariant_Procedure_Body): Add refactored calls
5886 and integrated code from Add_Parent_Invariants and
5887 Add_Interface_Invariants.
5888 (Process_Type): Removed, the
5889 relavant code was inlined into both Add_Own_Invariant and
5890 Add_Inherited_Invariant.
5892 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5894 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5911 and Build_Invariant_Procedure_Declaration.
5912 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5913 and Build_Invariant_Procedure_Declaration from exp_ch7
5914 and break-out Is_Untagged_Private_Derivation from
5915 Build_Invariant_Procedure_Body.
5916 (Replace_Type_References):
5917 Append an extra parameter to allow for dispatching replacements
5918 and add the corrasponding logic.
5919 (Type_Invariant): Remove
5920 Replace_Typ_Refs and replace its references with calls to
5921 Replace_Type_References.
5922 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5924 2017-04-25 Bob Duff <duff@adacore.com>
5926 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5927 that returns True when appropriate.
5928 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5929 when compiling predefined files.
5930 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5931 "gnat.adc" should not be considered a predefined file name.
5932 That required (or at least encouraged) a lot of cleanup of global
5933 variable usage. We shouldn't be communicating information via
5934 the global name buffer.
5935 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5936 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5939 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5941 * osint.adb (Find_File): Handle properly a request for a
5942 configuration file whose name is a directory.

5955 * sem_prag.adb: Remove suspicious uses of Name_Buf.
5956 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5957 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5958 Add String_To_Name with no side effects.
5960 2017-04-25 Justin Squirek <squirek@adacore.com>
5962 * sem_ch3.adb (Analyze_Declarations): Add
5963 additional condition for edge case.

5967 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5968 reserved words inside pragmas. This is necessary to allow the
5969 pragma name Interface to be used in pragma Ignore_Pragma.
5970 * par.adb: Minor comment fix.
5972 2017-04-25 Javier Miranda <miranda@adacore.com>
5974 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

5995 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
5996 the first pass over an assignment statement with target names,
5997 to prevent the generation of subtypes (such as discriminated
5998 record components)that may carry the target name outside of the
5999 tree for the assignment. The subtypes will be generated when
6000 the assignment is reanalyzed in full.
6001 (Analyze_Target_Name): Handle properly class-wide types.
6003 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

6011 and resolve the triaged expression because all substitutions
6012 refer to the proper entities. Update the replacement of

6015 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6016 are now only processed when freezing occurs. Build a body only

6033 properties of the private type to the full view in case the full
6034 view derives from a parent type and inherits a DIC pragma.
6035 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6036 DIC pragma is placed at the top of a declarative region.
6038 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6040 * a-tasatt.adb: Complete previous change and use an unsigned
6041 int to avoid overflow checks.
6043 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6045 * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
6046 the error message when the attribute reference is an actual in
6047 a call to a subprogram inherited from a generic formal type with
6048 unknown discriminants, which makes the subprogram and its formal
6049 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6051 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6053 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6056 2017-04-25 Bob Duff <duff@adacore.com>
6058 * sem_attr.adb (Type_Key): Add code in the
6059 recursive Compute_Type_Key to protect against fetching the source
6060 code for Standard, in case a component of the type is declared
6061 in Standard. There was already code to do this for the original
6062 type, but not for its components.
6064 2017-04-25 Javier Miranda <miranda@adacore.com>
6066 * exp_ch3.adb (Build_Initialization_Call): Handle
6067 subtypes of private types when searching for the underlying full
6068 view of a private type.
6070 2017-04-25 Javier Miranda <miranda@adacore.com>
6072 * sem_res.adb (Set_Mixed_Mode_Operand): A universal
6073 real conditional expression can appear in a fixed-type context

6760 (Check_Dependency_Clause): Properly detect a match between two
6761 'Result attributes. Update the various post-match cases to use

6825 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6826 an object declaration for an array type with a modular index type
6827 with the size of Long_Long_Integer. Special processing is needed
6828 in this case to compute reliably the size of the object, and
6829 eventually to raise Storage_Error, when wrap-around arithmetic
6830 might compute a meangingless size for the object.
6832 2017-01-23 Justin Squirek <squirek@adacore.com>

6839 * sem_res.adb (Resolve_Call): In the part of the code where
6840 it is deciding whether to turn the call into an indexed
6841 component, avoid doing so if the call is to an instance of
6842 Unchecked_Conversion. Otherwise, the compiler turns it into an
6843 indexed component, and resolution of that turns it back into a
6844 function call, and so on, resulting in infinite recursion.
6845 * sem_util.adb (Needs_One_Actual): If the first formal has a
6846 default, then return False.

6893 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6894 must be treated as delayed aspect even if the expression is

6948 returns a limited view of a type and at the point of the call the
6949 function is not declared in the extended main unit then replace
6950 it with the non-limited view, which must be available. If the
6951 called function is in the extended main unit then no action is
6952 needed since the back-end handles this case.

6966 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6967 base type differs from that of the completion and the private
6968 subtype is an itype (created for a constraint on an access

7258 * exp_ch6.adb (Expand_Call): Remove side effects on
7259 actuals that are allocators with qualified expression since the
7260 initialization of the object is performed by means of individual

7265 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7266 (Build_Derived_Enumeration_Type): If the derived type inherits a
7267 dynamic predicate from its parent, the bounds of the type must
7268 freeze because an explicit constraint is constructed for the

7354 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7356 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7357 selected component has a prefix that might be interpreted
7358 as a parameterless function call, but none of the candidate
7359 interpretations is parameterless, and there is a hidden homonym
7360 of the prefix that is a package.
7361 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7362 interpreted as a parameterless function call and its analysis
7363 fails, do not call Analyze_Selected_Component.

7367 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7369 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7370 calls to a newly-defined Scalar_Range_Of_Right_View function.

7377 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7378 from repeated code of Traverse_Compilation_Unit.
7379 (Traverse_Declaration_Or_Statement): fixed detection of
7380 generic subprograms and packages; also, iteration over case
7381 statement alternatives rewritten to avoid testing if the first
7382 alternative is present (since it must be present due to Ada
7383 syntax restrictions).
7385 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7387 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as

7398 identifier nodes that do not come from source, to handle properly
7399 dimensionality check within an inlined body which inclddes both
7400 original operands and rewritten operands. This removes spurious
7401 dimensionality errors in the presence of front-end inlining,
7402 as well as in SPARK mode.
7404 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7477 of an expression-function may have iterators and loops with
7478 defining identifiers which, as part of the preanalysis of the
7479 expression, may be left decorated with itypes that will not be
7480 available in the tree passed to the backend.
7482 2017-01-13 Ed Schonberg <schonberg@adacore.com>

7520 2017-01-13 Bob Duff <duff@adacore.com>
7522 * binde.adb (Elab_New): New elaboration order algorithm
7523 that is expected to cause fewer ABE issues. This is a work in
7524 progress. The new algorithm is currently disabled, and can be
7525 enable by the -dp switch, or by modifying the Do_Old and Do_New
7526 etc. flags and rebuilding. Experimental code is included to
7527 compare the results of the old and new algorithms.
7528 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7529 can have multiple of these tables, so the old and new algorithms
7531 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7532 parameter of type array. This avoids the global variable, and
7533 allows bounds checking (which is normally defeated by the tables
7534 packages). It also ensures that the Elab_Order is read-only
7536 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7537 subprograms that need it, as above.
7538 * debug.adb: Document new -dp switch. Modify doc of old -do
7540 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7541 and Bindgen. Move writing of closure (-R and -Ra switches)

7546 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7547 function is a completion, all entities referenced in the
7548 expression are frozen. As a consequence, a reference to an
7549 uncompleted private type from an enclosing scope is illegal.
7551 2017-01-13 Javier Miranda <miranda@adacore.com>
7553 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7554 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7555 expression function declaration that is a completion, its
7556 expression causes freezing (AI12-0103).
7558 2017-01-13 Vadim Godunko <godunko@adacore.com>
7560 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7572 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7573 restriction No_Tasking is in effect.
7574 (Build_Master_Renaming): Do not rename a master when restriction
7575 No_Tasking is in effect.

7616 Iterated_Component_Association: loop variable has the identifier
7617 of the original association. Generate a loop even for a single
7618 component choice, in order to make loop parameter visible in
7620 (Flatten): An Iterated_Component_Association is not static.

7644 mode a choice that is a subtype with a static predicate is
7645 replaced by the values it covers. This transformation must not

7670 has a Discrete_Choices list, as specified in the RM. A
7671 Component_Association for aggregate uses instead a Choices list.

7708 when not applicable due to actual requiring type conversion
7709 with possible check but no temporary value can be copied for
7710 GNATprove to see the check.
