328 2017-09-08 Yannick Moy <moy@adacore.com>
330 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
331 return the entity associated with the call.
332 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
333 Replace the internal Get_Function_Id with the new
334 Sem_Aux.Get_Called_Entity.
335 (Iterate_Call_Parameters): New
336 procedure to iterate on formals and actuals at the same time.
337 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
338 Set SPARK_Mode from spec when set, for analysis
339 of instance. Restore after analysis of instance.
340 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
341 set, for analysis of body instance. Restored automatically at
342 the end of the subprogram.
343 * gnat1drv.adb (Adjust_Global_Switches): Set
344 Check_Validity_Of_Parameters to False in GNATprove mode.
345 * opt.ads (Check_Validity_Of_Parameters): Document switch to
348 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
350 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
351 (New_Copy_Tree): ...there. Reset the hash tables only if they
352 were used in the previous invocation.
353 * s-htable.adb: Fix typo.
355 2017-09-08 Bob Duff <duff@adacore.com>
357 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
359 2017-09-08 Arnaud Charlet <charlet@adacore.com>
361 * sem_aggr.adb: minor style fix.
363 2017-09-08 Bob Duff <duff@adacore.com>
365 * sprint.adb (Write_Corresponding_Source): Ignore if there is
366 no current source file.
367 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
368 Print something helpful in case N is invalid.
369 * sprint.ads: Minor comment fix.
371 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
373 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
376 2017-09-08 Bob Duff <duff@adacore.com>
378 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
379 Ada_2020, along the same lines as the other Ada version pragmas.
381 2017-09-08 Gary Dismukes <dismukes@adacore.com>
383 * sem_ch12.adb: Minor typo fixes and reformatting.
385 2017-09-08 Yannick Moy <moy@adacore.com>
387 * sem_aggr.adb (Resolve_Record_Aggregate):
388 Rewrite bounds of aggregate subexpressions which may depend on
389 discriminants of the enclosing aggregate.
391 2017-09-08 Yannick Moy <moy@adacore.com>
393 * sem_ch5.adb: Prevent assertion failure on illegal code.
395 2017-09-08 Yannick Moy <moy@adacore.com>
397 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
398 calling Renamed_Entity on an entity which cannot be a renaming.
400 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
402 * exp_aggr.adb: Add with & use clause for Urealp.
403 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
404 elementary types instead of just discrete types.
405 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
406 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
407 Be prepared for the FP zero value in the memset case. Add small
410 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
412 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
415 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
417 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
418 of New_Copy because the latter leaves the syntactic structure of
419 the tree inconsistent (a child is accessible through two parents)
420 and prevents proper replication of itypes by subsequent calls
422 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
423 New_Copy because the latter leaves the syntactic structure of the
424 tree inconsistent (a child is accessible through two parents)
425 and prevents proper replication of itypes by subsequent calls
427 * sem_util.adb (In_Subtree): New routine.
428 (New_Copy_Tree): Reimplemented.

432 2017-09-08 Ed Schonberg <schonberg@adacore.com>
434 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
435 for aspect Default_Value is a static scalar value, but it does
436 not freeze the type. Yhis allows for subsequent representation
437 clauses for the type.
439 2017-09-08 Javier Miranda <miranda@adacore.com>
441 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
442 not add entries into the undefined reference table when we are
443 compiling with errors ignored.
445 2017-09-08 Ed Schonberg <schonberg@adacore.com>
447 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
448 check if the instance is within an enclosing instance body. The
449 formal package was legal in the enclosing generic, and is
450 legal in the enclosing instantiation. This optimisation may be
451 applicable elsewhere, and it also removes spurious errors that
452 may arise with on-the-fly processing of instantiations that
453 contain Inline_Always subprograms.
455 2017-09-08 Vincent Celier <celier@adacore.com>
457 * gnatcmd.adb: Disregard empty argument of GNAT driver.
459 2017-09-08 Justin Squirek <squirek@adacore.com>
461 * checks.adb (Insert_Valid_Check): Manually decorate
462 the generated temporary for range valdity checks.
464 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
466 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
468 2017-09-08 Justin Squirek <squirek@adacore.com>
470 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
471 case to handle underscore flags.
472 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
473 new procedure to handle underscores.
475 2017-09-08 Javier Miranda <miranda@adacore.com>
477 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
478 divisions with fixed point results to avoid generating twice
479 the runtime check on divide by zero.
480 * checks.adb (Apply_Divide_Checks): Ensure that operands are
481 not evaluated twice (once for their runtime checks and once for
482 their regular computation).
484 2017-09-08 Yannick Moy <moy@adacore.com>
486 * sem_prag.adb (Analyze_Part_Of): Add missing
487 return statements after issuing errors. Add detection of
488 out-of-order item and single concurrent type.

603 literals, so that Pure_Barriers is no longer in range of the
604 Cunit_Boolean_Restrictions subtype.

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

700 defining identifier as referenced to prevent spurious warnings:
701 corresponding loop is expanded into one or more loops whose
702 variable has the same name, and the expression uses those names
703 and not the original one.

813 access to interface types. Remove also the accessibility check.
815 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
817 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
818 all the types that are referenced by the expression.
819 (Analyze_Expression_Function): Call Freeze_Expr_Types for
820 a completion instead of manually freezing the type of the
822 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
824 2017-09-08 Ed Schonberg <schonberg@adacore.com>
826 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
827 New procedure, auxiliary to Expand_Pragma_Check, to handle
828 references to the discriminants of a protected type within a
829 precondition of a protected operation. This is needed because
830 the original precondition has been analyzed in the context of
831 the protected declaration, but in the body of the operation
832 references to the discriminants have been replaved by references
833 to the discriminants of the target object, and these references
834 are only created when expanding the protected body.
836 2017-09-08 Yannick Moy <moy@adacore.com>
838 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
841 2017-09-08 Ed Schonberg <schonberg@adacore.com>

845 discriminants, or for variant parts that depend on them.
847 2017-09-08 Justin Squirek <squirek@adacore.com>
849 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
850 Find_Comparison_Type.Try_One_Interp): Add check for generic
853 2017-09-08 Arnaud Charlet <charlet@adacore.com>

873 the underlying type to handle limited-withed types.
875 2017-09-08 Ed Schonberg <schonberg@adacore.com>
877 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
878 over a subtype of a type with a static predicate, taking into
879 account the predicate function of the parent type and the bounds
880 given in the loop specification.
881 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
882 a loop specification that is a subtype indication whose type mark
883 is a type with a static predicate, inherit predicate function,
884 used to build case statement for rewritten loop.
886 2017-09-08 Justin Squirek <squirek@adacore.com>
888 * lib-load.adb: Modify printing of error message to exclude file
891 2017-09-08 Arnaud Charlet <charlet@adacore.com>
893 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
894 don't inline subprograms declared in both visible and private
896 (In_Package_Spec): previously In_Package_Visible_Spec; now
897 detects subprograms declared both in visible and private parts
900 2017-09-08 Ed Schonberg <schonberg@adacore.com>
902 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
903 the type is an anonymous array in an object declaration, whose
904 component type has an invariant, use the object declaration
905 as the insertion point for the invariant procedure, given that
906 there is no explicit type declaration for an anonymous array type.
908 2017-09-08 Bob Duff <duff@adacore.com>
910 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

919 source file is missing.
921 2017-09-08 Bob Duff <duff@adacore.com>
924 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
925 Default_WCEM by default (i.e. if the encoding is not specified
928 2017-09-08 Bob Duff <duff@adacore.com>
930 * s-trasym.ads (Hexa_Traceback): If
931 Suppress_Hex is True, print "..." instead of a hexadecimal
933 * s-trasym.adb: Ignore No_Hex in this version.
936 2017-09-08 Bob Duff <duff@adacore.com>
938 * debug.adb: Minor reformatting.
940 2017-09-08 Bob Duff <duff@adacore.com>
942 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
943 code so it doesn't trigger an "uninit var" warning.

947 * s-hibaen.ads: Remove obsolete file.
949 2017-09-08 Arnaud Charlet <charlet@adacore.com>

959 Initializes) and bodies (for pragma Refined_State).
961 2017-09-08 Bob Duff <duff@adacore.com>

966 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
968 * debug.adb (dA): Adjust comment.
969 * gnat1drv.adb (Gnat1drv): Likewise.
970 * opt.ads (List_Representation_Info_Extended): New variable.
971 * repinfo.adb (List_Record_Info): Split implementation into...
972 (Compute_Max_Length): ...this. Recurse on records if requested.
973 (List_Record_Layout): Likewise.
974 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
975 statement, accept '0' and set List_Representation_Info_Extended
977 * usage.adb (Usage): Document new -gnatRe variant.
979 2017-09-08 Ed Schonberg <schonberg@adacore.com>
981 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
982 Do not save the given entity in the global variable Default_Pool
983 if the pragma appears within a generic unit.
985 2017-09-08 Bob Duff <duff@adacore.com>
987 * errout.adb (Delete_Warning): Do not
988 decrement Warnings_Treated_As_Errors. This is called before
989 Warnings_Treated_As_Errors has been incremented to account for
990 this warning. Decrementing it here can lead to negative values
991 of Warnings_Treated_As_Errors, raising Constraint_Error in
992 checks-on builds, and causing the compiler to return an error
993 code in checks-off builds.
995 2017-09-08 Arnaud Charlet <charlet@adacore.com>
997 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
998 entities of named concurrent types as Ref_Id and not of anonymous
999 concurrent objects (because callers already know when a conversion
1000 is necessary and can easily do it); also, do not expect protected
1001 types or protected objects as Context_Id (because no flow-related
1002 SPARK pragmas are attached there); reflect these changes in a
1003 more precise comment.
1005 2017-09-08 Olivier Hainque <hainque@adacore.com>
1007 * g-altive.ads: Add documentation.
1009 2017-09-08 Bob Duff <duff@adacore.com>

1012 * erroutc.ads: Comment fix.
1014 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1016 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
1017 for compatibility of component types of formal and actual in an
1018 instantiation of a child unit, when the component type of the
1019 formal is itself a formal of an enclosing generic.
1021 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1023 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1024 sem_prag.adb to make it available for GNATprove; for concurrent
1025 types replace custom scope climbing with Scope_Same_Or_Within; for
1026 single concurrent objects add scope climbing (with Scope_Within),
1027 which was not there (that's the primary semantic change of this
1028 commit); also, when comparing a single concurrent object with
1029 its corresponding concurrent type rely on equality of types,
1030 not of objects (because that's simpler to code).
1031 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1032 (Analyze_Global_Item): adjust special-casing of references to the
1033 current instance of a concurrent unit in the Global contracts
1034 of task types and single tasks objects; similar for references
1035 in the protected operations and entries of protected types and
1036 single protected objects (in all these cases the current instance
1037 behaves as an implicit parameter and must not be mentioned in
1038 the Global contract).
1040 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1042 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1043 function calls returning a record within a subprogram call,
1046 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1048 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1049 name that designates the current instance of a child unit in its
1050 own body and appears as the prefix of a reference to an entity
1051 local to the child unit.
1052 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:

1578 Add missing implicit type conversion to force displacement of the
1581 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
1583 * sem_ch3.adb, sem_aux.adb, sem_res.adb: Minor reformatting.
1585 2017-09-06 Yannick Moy <moy@adacore.com>
1587 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
1588 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
1590 2017-09-06 Bob Duff <duff@adacore.com>
1592 * sem_ch8.adb: Change Assert to be consistent with
1595 2017-09-06 Bob Duff <duff@adacore.com>
1597 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1598 requested. Previously, the -do switch meant "run Elab_New and
1599 Elab_Old and use the order chosen by Elab_Old, possibly with
1600 debugging printouts comparing the two orders." Now it means
1601 "do not run Elab_New." This is of use if there are bugs that
1602 cause Elab_New to crash.
1603 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1605 * ali.ads (Elab_Position): Change type to Nat, to avoid various
1608 2017-09-06 Arnaud Charlet <charlet@adacore.com>
1610 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
1611 reference to SPARK RM.
1613 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1615 * layout.adb: Use SSU short hand consistently throughout the file.
1617 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1619 * freeze.adb (Freeze_Record_Type)
1620 <Sized_Component_Total_Round_RM_Size>: New local variable to
1621 accumulate the rounded RM_Size of components. Update it for
1622 every component whose RM_Size is statically known. Add missing
1623 guard to check that bit packing is really required before issuing
1624 the error about packing. Swap condition for clarity's sake.
1625 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

1644 project manager sources.
1646 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1648 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1649 entity of a mutable type and the right-hand side is a conditional
1650 expression, resolve the alternatives of the conditional using
1651 the base type of the target entity, because the alternatives
1652 may have distinct subtypes. This is particularly relevant if
1653 the alternatives are aggregates.
1655 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1657 * checks.adb (Apply_Predicate_Check): If the expression is an
1658 aggregate that is the RHS of an assignment, apply the check to
1659 the LHS after the assignment, rather than to the aggregate. This
1660 is more efficient than creating a temporary for the aggregate,
1661 and prevents back-end crashes when the aggregate includes a
1662 dynamic "others' association.
1664 2017-09-06 Yannick Moy <moy@adacore.com>
1666 * sem_ch12.adb (Analyze_Instance_And_Renamings):

1668 of the generated package declaration.
1670 2017-09-06 Yannick Moy <moy@adacore.com>
1672 * sem_res.adb (Resolve_Call): Do not issue a
1673 message for calls inside expression function, unless body was
1674 seen and is candidate for inlining.
1676 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1678 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
1679 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
1680 body. do not freeze the formals of the generic unit.
1682 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1684 * errout.adb (Error_Msg): Separate the
1685 treatment for warning vs. style messages in inlinings and
1686 instantiations. Prevents blowups on calls to Warn_Insertion for
1687 style messages, which should not be called in that case because
1688 Warning_Msg_Char is not set.
1690 2017-09-06 Justin Squirek <squirek@adacore.com>
1692 * sem_prag.adb (Check_VFA_Conflicts): Created
1693 to group all Volatile_Full_Access checks relating to other
1694 representation pragmas (Mark_Component_Or_Object): Created
1695 to centeralize the flagging of attributes for the record type
1696 component case, a pragma applied individually to a component, and
1698 (Process_Atomic_Independent_Shared_Volatile):
1699 Add propagation of certain pragmas to record components and move
1700 evaluation of VFA checks
1702 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1704 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):

1713 2017-09-06 Bob Duff <duff@adacore.com>
1715 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1716 that is a proper body corresponding to a stub, we defer the
1717 adjustment of the sloc until after the correct adjustment has
1718 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1719 the adjustment, because it will be outside the range in (the old,
1720 incorrect) S_Adjustment.
1721 * inline.adb: Use named notation for readability and uniformity.
1722 * sinput-l.adb: Minor improvements to debugging output printed
1724 * sinput-l.ads (Create_Instantiation_Source): Minor comment
1727 2017-09-06 Vincent Celier <celier@adacore.com>

1733 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a

1739 2017-09-06 Justin Squirek <squirek@adacore.com>
1741 * einfo.adb (Set_Linker_Section_Pragma): Modify
1742 Set_Linker_Section_Pragma to be consistant with the "getter"
1743 Linker_Section_Pragma.
1744 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1745 checking for container loops so that the index cursor is not
1746 directly changable by the user with the use of E_Loop_Parameter.
1747 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

1791 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
1792 Generate a freeze node for the actual of a formal package, if
1793 the actual is declared in the same unit and has a corresponding
1794 body, to prevent the current instance from being frozen before
1797 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

1819 missing case of controlled generalized indexing.
1820 (Is_Source_Object): Use routine Strip to remove indirections.
1821 (Strip): New routine.
1823 2017-09-06 Bob Duff <duff@adacore.com>
1825 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1826 we include the proper header. Otherwise, we just declare the necessary
1827 things from the capabilities library. This is so we can build on
1828 machines without that library, while still enabling that library.
1829 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1830 simply return 0 if the library is not present, or not included
1833 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
1835 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

1846 has no parameter specification and no entry index, use the entry name
1847 as the end of the generated SCO statement.
1849 2017-09-06 Steve Baird <baird@adacore.com>
1851 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1852 uses of 'Image and related attributes as having side effects in
1853 order to avoid replicating such uses.
1854 * pprint.ads (Expression_Image) Add new generic formal flag
1855 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1856 (eventually) override the default.
1857 * pprint.adb (Expression_Image) If the new flag is set, then
1858 suppress the ".all" suffix when displaying a dereference whose
1859 prefix is a use of a value-capturing compiler temp of the sort
1860 generated by Expr_Util.Remove_Side_Effects .

1876 so that applies to any entity.
1878 2017-09-06 Yannick Moy <moy@adacore.com>
1880 * sem_ch3.adb (Derived_Type_Declaration): Use
1881 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1883 2017-09-06 Javier Miranda <miranda@adacore.com>
1885 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1888 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1890 * sem_dim.adb (Analyze_Dimension): In an instance, a type
1891 conversion takes its dimensions from the expression, not from
1893 (Dimensions_Of_Operand): Ditto.
1895 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1897 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
1898 null procedures when GNAT coverage is used, so that their (empty)
1899 bodies are properly covered.

1903 * sem_ch13.adb (Resolve_Aspect_Expressions): If
1904 the entity is a type with discriminants, make the discriminants

1909 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
1910 Universal_Real and the context is a floating-point type, resolve
1911 both operands to the target type.

1918 2017-09-06 Yannick Moy <moy@adacore.com>
1920 * freeze.adb (Check_Inherited_Conditions): Rewriting
1921 of inherited preconditions and postconditions should only occur
1922 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1923 be confused with SPARK_Mode being On.
1925 2017-09-06 Yannick Moy <moy@adacore.com>

1938 on the procedure created to encapsulate the body.
1939 * sem_ch7.adb: Add with clause for GNAT.HTable.
1940 (Entity_Table_Size): New constant.
1941 (Entity_Hash): New function.
1942 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1943 (Is_Subprogram_Ref): Rename into...
1944 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1945 the table instead of bailing out on them. Scan the value of constants
1946 if it is not known at compile time.
1947 (Contains_Subprograms_Refs): Rename into...
1948 (Scan_Subprogram_Refs): ...this.
1949 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1950 Is_Public flag on subprograms if they are not actually referenced.
1951 (Hide_Public_Entities): Beef up comment on the algorithm.
1952 Reset the table of subprograms on entry.
1954 2017-09-06 Yannick Moy <moy@adacore.com>

2008 2017-09-06 Bob Duff <duff@adacore.com>
2010 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
2011 check back to the body, because SPARK is not yet ready for
2012 "or else raise Constraint_Error".

2039 * sem_type.adb (Interface_Present_In_Ancestor): Within an
2040 expression function, or within a spec expression (default value,
2041 etc) a reference to an incomplete type is legal: legality of
2042 the operation will be checked when some related entity (type,
2043 object or subprogram) is frozen.
2045 2017-09-06 Gary Dismukes <dismukes@adacore.com>
2047 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

2059 we can use modern Ada in this package.
2060 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2061 Move Ada.Command_Line.Response_File to System.Response_File,
2062 and make Ada.Command_Line.Response_File into a rename of
2063 System.Response_File. This is to avoid having gnatbind depend
2064 Ada.Command_Line, which would damage the bootstrap process now
2065 that Ada.Command_Line contains modern Ada (the raise expression).
2066 * gnatbind.adb: Avoid dependence on
2067 Ada.Command_Line. Depend on System.Response_File instead
2068 of Ada.Command_Line.Response_File. Change one call to
2069 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2070 to Ada.Command_Line.Argument_Count to use Arg_Count.

2142 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
2144 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

2206 of the right-hand side has stored constraint, use its values
2207 (except for those that are renamings of parent discriminants)
2208 to produce additional assignments for the discriminants of the
2209 left-hand side, which are invisible in the righ-hand side and
2210 not retrievable as selected components.
2212 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2214 * sem_util.adb (Needs_One_Formal): The first formal of such a

2253 constraint for it, given that the constrained discriminants are
2254 not visible in the object.
2255 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2256 side may be derived from that of the left-hand side (as in the
2257 case of an assignment with a change of representation) so the
2258 discriminant to be used in the retrieval of the value of the
2259 component must be the entity in the type of the right-hand side.

2288 in a set membership is an overloaded enumeration literal, and
2289 the type of the alternative is resolved from a previous one,
2290 replace the entity of the alternative as well as the type,
2291 to prevent inconsistencies between the entity and the type.

2834 * exp_ch6.adb (Expand_Call_Helper): When locating the
2835 accessibility entity created for an access parameter, handle
2836 properly a reference to a formal of an enclosing subprogram. if
2837 the reference appears in an inherited class-wide condition, it
2838 is the rewriting of the reference in the ancestor expression,
2839 but the accessibility entity must be that of the current formal.
2841 2017-05-02 Javier Miranda <miranda@adacore.com>
2843 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

2879 procedure body for a local (sub)type declaration within a
2880 predicate function. Invariant checks do not apply to these, and
2881 the expansion of the procedure will happen in the wrong scope,
2882 leading to misplaced freeze nodes.
2884 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2886 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2887 to analyze generated actions. If the main unit is a body,

2892 * einfo.adb (Declaration_Node): flip branches of

2923 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2924 Refine predicate for the case where the primitive operation
2925 is a renaming of equality. An overriding operation that is
2926 a user-defined renaming of predefined equality inherits its
2927 slot from the overridden operation. Otherwise it is treated
2928 as a predefined op and occupies the same predefined slot as
2929 equality. A call to it is transformed into a call to its alias,
2930 which is the predefined equality. A dispatching call thus uses
2931 the proper slot if operation is further inherited and called
2932 with class-wide arguments.
2934 2017-05-02 Justin Squirek <squirek@adacore.com>
2936 * errout.adb (Set_Msg_Text): Add a case to switch the message

2969 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2970 statement if the initialization call is a null procedure, as
2971 can happen with a controlled type with no explicit Initialize
2972 procedure, or an array of such.

2974 controlled components that has a trivial Initialize procedure,
2975 insert declaration for finalization counter after object

2978 finalization block and attendant declarations if component has
2979 a trivial Initialize procedure.

2981 a trivial Initialize procedure.

3011 2017-05-02 Gary Dismukes <dismukes@adacore.com>
3013 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
3014 parameter Array_Comp to indicate the case of an array object
3015 with null-excluding components.
3016 * checks.adb (Null_Exclusion_Static_Checks):
3017 Call Compile_Time_Constraint_Error instead of
3018 Apply_Compile_Time_Constraint_Error in the component case. Also
3019 call that when Array_Comp is True, with an appropriate warning for
3020 the array component case. Only create an explicit initialization
3021 by null in the case of an object of a null-excluding access type
3022 (and no longer do that in the component case).
3023 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3024 Array_Comp defaulted to False. Pass Empty for the Comp
3025 actual when calling Null_Exclusion_Static_Checks in the case
3026 where Comp_Decl matches Object_Decl, because we don't have a
3027 component in that case. In the case of an object or component
3028 of an array type, pass True for Array_Comp on the recursive call

3033 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3034 compute the linux priority from the Ada priority. Call this everywhere
3035 required. In particular, the previous version was not doing this
3036 computation when setting the ceiling priority in various places. It
3037 was just converting to C.int, which results in a ceiling that is off
3040 2017-05-02 Ed Schonberg <schonberg@adacore.com>

3059 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3060 here from exp_ch9, to recognize objects whose creation requires

3074 visibility rules for equality operators that apply within an
3075 instantiation apply within an inlined body.

3133 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3135 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3136 Simplify the expression for a fixed-fixed division to remove

3142 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3144 2017-05-02 Bob Duff <duff@adacore.com>
3146 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3147 to find primitive ops, instead of using an Identifier that will
3148 later be looked up. This is necessary because these ops are not
3149 necessarily visible at all places where we need to call them.
3150 * exp_util.ads: Minor comment fix.
3152 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3154 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3155 references are fully conformant if they are both expansions
3156 of the discriminant of a protected type, within one of the
3157 protected operations. One occurrence may be expanded into a
3158 constant declaration while the other is an input parameter to
3159 the corresponding generated subprogram.

3163 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3164 recursivly searching composite-types for null-excluding access
3165 types and verifying them.
3166 (Analyze_Object_Declaration): Add a
3167 call to Check_Null_Excluding_Components for static verification
3168 of non-initialized objects.
3169 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added

3189 array components specially.
3191 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3193 * sem_ch8.adb (Premature_Usage): If the premature usage of
3194 an entity is as the expression in its own object decaration,
3195 rewrite the reference as Any_Id to prevent cascaded errors or
3196 compiler loops when such an entity is used in an address clause.
3198 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3200 * gcc-interface/decl.c (components_to_record): Add missing guard.

3205 Put back pending fields onto the regular list if the misalignment
3206 happens to cancel itself.
3208 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3210 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3211 controlling actual in a prefixed call, preserve the original node
3212 information if the prefix itself has been rewritten, for ASIS use.
3214 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3216 * exp_ch6.adb (Insert_Post_Call_Actions):
3217 Code clean up. Insert the post-call actions after an enclosing
3218 procedure call when N denotes a function call and appears as an
3219 actual parameter in the procedure call.
3221 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3223 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3224 for the component, also reject the attribute if the component
3225 doesn't end on a byte boundary and its scalar storage order is
3226 different from that of the enclosing record type.
3228 2017-04-28 Javier Miranda <miranda@adacore.com>
3230 * atree.ads (Info_Messages): Removed.

3260 2017-04-28 Bob Duff <duff@adacore.com>
3262 * sem_util.ads, sem_util.adb (Might_Raise): New function
3263 that replaces Is_Exception_Safe, but has the opposite
3264 sense. Is_Exception_Safe was missing various cases -- calls inside
3265 a pragma Debug, calls inside an 'if' or assignment statement,
3266 etc. Might_Raise now walks the entire subtree looking for things
3268 * exp_ch9.adb (Is_Exception_Safe): Remove.
3269 (Build_Protected_Subprogram_Body): Replace call to
3270 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3271 constants where possible).
3272 * exp_ch7.adb: Rename Is_Protected_Body -->
3273 Is_Protected_Subp_Body. A protected_body is something different
3276 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

3302 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3303 Interrupt_Handler and Attach_Handler): Generate reference
3304 to protected operation to prevent spurious warnings about
3305 unreferenced entities. Previous scheme failed with style checks
3308 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3310 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3311 that follows an expression function must not be relocated to
3312 the generated body, because it applies to the code that follows.
3314 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3316 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3317 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3318 code that might violate the more stringent checking for 'Access
3319 introduced in Ada 2005.
3321 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3323 * a-cforse.adb: minor style fix in comment.
3325 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3327 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3328 initialize Block_Decls variable.
3329 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3330 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

3339 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3341 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3343 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3344 node between access types, freeze the designated type as well,
3345 so that dispatch table pointers are created in the proper scope,
3346 and not in the constructed body of the expression function.
3348 2017-04-28 Bob Duff <duff@adacore.com>
3350 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3351 value makes large compilations faster, but small compilations slower.
3353 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3355 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3357 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3359 * erroutc.adb (Compilation_Errors): Do not consider info messages
3360 as suitable warnings when warnings must be treated as errors.
3361 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3362 internally-generated packages when outputting completion
3364 * errout.adb (Output_Messages): Do not consider info messages as

3367 suitable warnings when warnings must be treated as errors.
3369 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3371 * warnsw.ads: Minor fix for incorrect wording in comment.
3373 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3375 * sem_res.adb (In_Instance_Code): New predicate in
3376 Valid_Conversion, to determine whether a type conversion appears
3377 as (or within) an actual for a formal object. Type conversions
3378 in instances are not rechecked in Valid_Conversion because
3379 visibility changes between generic location andi instance may
3380 lead to spurious errors, but conversions within an actual must be
3381 fully checked, and they are not fully resolved when pre-analyzing
3384 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3386 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3387 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3388 of the relocated node will have mangled Parent pointers.
3389 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3390 tables used in conjunction with entity and itype replication.
3391 (Visit_Entity): Rewrite the restriction on which entities
3392 require duplication. The restriction now includes all types.
3394 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>

3426 (Restore_Warnings): Likewise.
3427 (Save_Warnings): Likewise.
3428 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3429 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3430 components_to_record.
3431 (gnu_field_to_gnat): New function.
3432 (warn_on_field_placement): Likewise.
3433 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3434 parameters. Rename local variables and adjust recursive call.
3435 Rework final scan of the field list and implement warnings on the
3436 problematic placement of specific sorts of fields.
3438 2017-04-27 Bob Duff <duff@adacore.com>
3440 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

3445 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3446 For efficiency, cache results of Is_Internal_File_Name and
3447 Is_Predefined_File_Name in the Units table. This avoids a lot
3448 of repeated text processing.
3450 2017-04-27 Emmanuel Briot <briot@adacore.com>
3452 * g-comlin.adb (Sort_Sections): remove useless test.
3454 2017-04-27 Claire Dross <dross@adacore.com>
3456 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3457 allow the use of regular equality over elements in contracts.
3458 (Formal_Model): Ghost package containing model functions that are
3459 used in subprogram contracts.
3460 (Current_To_Last): Removed, model functions should be used instead.
3461 (First_To_Previous): Removed, model functions should be used instead.
3462 (Strict_Equal): Removed, model functions should be used instead.
3463 (No_Overlap): Removed, model functions should be used instead.
3464 (Equivalent_Keys): Functions over cursors are removed. They were
3465 awkward with explicit container parameters.
3466 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3467 allow the use of regular equality over elements in contracts.
3468 (Formal_Model): Ghost package containing model functions that

3475 2017-04-27 Yannick Moy <moy@adacore.com>
3477 * gnat1drv.adb: Code cleanup.
3479 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3481 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3482 attribute reference in a post- condition is the subprogram to
3483 which the condition applies. If the condition is inherited
3484 by a type extension, the prefix becomes a reference to the
3485 inherited operation, but there is no need to create a wrapper
3486 for this operation, because 'Result is expanded independently
3487 when elaborating the postconditions.
3489 2017-04-27 Bob Duff <duff@adacore.com>
3491 * sinput.adb: Minor code cleanup.
3492 * namet.adb (Append): Create faster versions of
3493 Append(String) and Append(Name_Id) by using slice assignment
3495 * sem_util.adb (In_Instance): Speed this up by removing
3496 unnecessary tests; Is_Generic_Instance is defined for all
3498 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3499 Remove unused function.
3500 * alloc.ads (Nodes_Initial): Use a much larger value, because
3501 the compiler was spending a lot of time copying the nodes table
3502 when it grows. This number was chosen in 1996, so is rather out
3503 of date with current memory sizes. Anyway, it's virtual memory.
3504 Get rid of Orig_Nodes_...; use Node_... instead.
3505 * atree.adb (Lock): Do not release the Nodes tables; it's a
3507 Orig_Nodes_ ==> Nodes_
3508 * nlists.adb: Orig_Nodes_ ==> Nodes_
3509 * g-table.adb: Remove unused "with" clause.
3510 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3511 not be used by clients.
3512 * g-dyntab.adb (Last_Allocated): New function
3513 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3515 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3517 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3519 (Subtypes_Statically_Match): Remove duplicate check.

3541 and selected components.

4083 modifications in functional containers.
4084 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4085 to improve readablity. Subprograms are separated between basic
4086 operations, constructors and properties. Universally quantified
4087 formulas in contracts are factorized in independant functions
4088 with a name and a comment. Names of parameters are improved.
4090 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4092 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.

4096 * sem_res.adb (Resolve_Type_Conversion): Do not
4097 install a predicate check here since this is already done during
4098 the expansion phase. Verify whether the operand satisfies the
4099 static predicate (if any) of the target type.
4100 * sem_ch3.adb (Analyze_Object_Declaration): Do
4101 not install a predicate check if the object is initialized by
4102 means of a type conversion because the conversion is subjected

4127 in gnat1 and gnatbind.
4128 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4129 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4176 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4178 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4179 the loop which detects potential enclosing transient scopes. The
4180 loop now terminates much earlier as transient scopes are bounded
4181 by packages and subprograms.
4183 2017-04-27 Claire Dross <dross@adacore.com>
4185 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4186 allow the use of regular equality over elements in contracts.
4187 (Cursor): Type is now public so that it can be used in
4189 (Formal_Model): Ghost package containing
4190 model functions that are used in subprogram contracts.
4191 (Current_To_Last): Removed, model functions should be used
4193 (First_To_Previous): Removed, model functions should
4195 (Strict_Equal): Removed, model functions
4196 should be used instead.
4197 (Append): Default parameter value
4198 replaced by new wrapper to allow more precise contracts.

4240 * debug.adb Change the documentation of switch -gnatd.s.
4241 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4242 to manage the secondary stack when an enclosing scope already
4243 performs this functionality (aka relaxed management). Switch
4244 -gnatd.s may be used to force strict management in which case
4245 the block will manage the secondary stack unconditionally. Add
4246 a guard to stop the traversal when encountering a package or a
4249 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4251 * sem_res.adb (Resolve_Call): Refine further the handling of
4252 limited views of return types in function calls. If the function
4253 that returns a limited view appears in the current unit,
4254 we do not replace its type by the non-limited view because
4255 this transformation is performed int the back-end. However,
4256 the type of the call itself must be the non-limited view, to
4257 prevent spurious resolution errors.
4259 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4261 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4262 Removed, proposed implementation using generics for class-wide
4263 preconditions proved impractical.
4264 (Class_Wide_Clone): New attribute of subprogram. Designates
4265 subprogram created for primitive operations with class-wide
4266 pre/postconditions that contain calls to other primitives. The
4267 clone holds the body of the original primitive, but the
4268 pre/postonditions do not apply to it. The original body is
4269 rewritten as a wrapper for a call to the clone.
4270 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4271 the flag is set, no code for the corresponding pre/postconditions
4272 is inserted into its body.
4274 2017-04-27 Bob Duff <duff@adacore.com>
4276 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

4287 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
4288 (Remove): New function that removes an element from a set.
4289 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
4290 (Remove): New function that removes an element from a sequence.
4291 (Insert): New function that adds anywhere in a sequence.

4304 of attribute 'Result is not considered a violation of pragma
4307 2017-04-27 Justin Squirek <squirek@adacore.com>
4309 * cstand.adb (Create_Standard): Correctly set

4320 private child of Ada.Containers used to implement all functional
4322 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4323 child of Ada.Containers. It provides functional indefinite unbounded
4324 maps which can be used as high level models for specification
4326 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4327 child of Ada.Containers. It provides functional indefinite unbounded
4328 sets which can be used as high level models for specification
4330 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4331 child of Ada.Containers. It provides functional indefinite unbounded
4332 vectors which can be used as high level models for specification
4334 * Makefile.rtl: Add new packages.
4335 * impunit.adb: Add new packages.
4337 2017-04-27 Gary Dismukes <dismukes@adacore.com>

4341 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4343 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4344 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4345 point type actual that has user-defined arithmetic primitives,
4346 when there is a previous actual for a formal package that defines
4347 a fixed-point type with the parent user-defined operator.
4349 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4351 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4352 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4353 the component type allows range checks.
4355 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4357 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4358 corresponding declaration, because formal derived types are
4359 rewritten as private extensions.
4361 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4363 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4364 dimensions of operands if node has been analyzed already, because
4365 previous analysis and dimension checking will have removed the
4366 dimension information from the operands.
4368 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4370 * debug.adb: Document the use of switch -gnatd.s.
4371 * einfo.ads Update the documentation on attribute
4372 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4373 the uses of these attributes from certain entities.

4375 which determines whether the block should continue to manage
4376 the secondary stack.

4430 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4431 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4432 Ada_2012 instead of Ada_2005 to be compatible with the above
4434 * bindgen.adb: Silence new warning on pragma Ada_95.
4436 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

4448 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4449 Fix spelling mistakes.
4451 2017-04-25 Bob Duff <duff@adacore.com>
4453 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4454 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4455 for source buffers. Fix misc obscure bugs.
4456 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4457 checking, for source buffers. Modify representation clause for
4458 Source_File_Record as appropriate. Move Source_File_Index_Table
4459 from spec to body, because it is not used outside the body.
4460 Move Set_Source_File_Index_Table into the private part, because
4461 it is used only in the body and in children. Use trickery to
4462 modify the dope in the generic instantiation case. It's ugly,
4463 but not as ugly as the previous method. Fix documentation.
4464 Remove obsolete code.
4465 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
4466 indexing in source buffers.

4480 expander is not active or when index/range checks are suppressed
4482 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4483 Remove variants that include a Supress parameter. These routines
4484 are never used, and were introduced before the current scope-based
4485 check suppression method.
4487 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

4506 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
4507 is now carried out by Null_Status.
4508 (Null_Status): New routine.

4516 completion, if the type is derived from a generic formal type.
4518 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4537 the Internal_Source buffer. This removes the incorrect call to "="
4538 the customer noticed.
4539 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4540 eventually need to eliminate them altogether. Or else get rid
4541 of zero-origin addressing.

5069 * a-numeri.ads: Go back to using brackets encoding for the Greek
5072 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5074 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5075 (10-15): if derived type T with progenitors is abstract,
5076 and primitive P of this type inherits non-trivial classwide
5077 preconditions from both a parent operation and from an interface
5078 operation, then the inherited operation is abstract if the parent
5079 operation is not null.
5080 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5081 with Covered_Interface_Op to yield the actual interface operation
5082 that is implemented by a given inherited operation.
5084 2017-04-25 Javier Miranda <miranda@adacore.com>
5086 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
5087 and right operands after performing the validity checks. Required
5088 because validity checks may remove side effects from the operands.
5090 2017-04-25 Javier Miranda <miranda@adacore.com>
5092 * exp_attr.adb (Attribute_Unrestricted_Access):
5093 Do not disable implicit type conversion. Required to generate
5094 code that displaces the pointer to reference the secondary

5105 values, and comparing them must use Expr_Value_S.
5107 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5109 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5110 dereference is introduced for the object, and the object is
5111 overloaded, do not check whether it is aliased, because it may
5112 include an implicit dereference.
5113 * sem_type.adb (Disambiguate): If two interpretations are access
5114 attribute types with the same designated type keep either of
5115 them and do not report an ambiguity. A true ambiguity will be
5118 2017-04-25 Bob Duff <duff@adacore.com>
5120 * a-numeri.ads: Change the encoding of Greek letter Pi from
5121 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5122 to indicate the encoding. We considered using a byte order mark
5123 (BOM), but that causes various trouble (misc software eats the
5124 BOM, if you have a patch with a BOM, then it's not at the start
5125 of the patch, so it's not a BOM, the BOM affects with-ing files,
5127 * scng.adb, s-wchcnv.adb: Minor.

5168 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
5169 enforce legality rule on classwide preconditions inherited from
5170 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5171 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5172 subprogram need not be dispatching if it appears in a precondition
5173 for an abstract or null subprogram.
5175 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5177 * sem_ch10.adb: Minor typo fix.

5181 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
5183 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5185 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
5186 have a length which is a power of 2.
5187 (Is_Predefined_File_Name): Likewise. Adjust comment.
5189 2017-04-25 Bob Duff <duff@adacore.com>
5191 * exp_aggr.adb (Component_Count): Protect the
5192 arithmetic from attempting to convert a value >= 2**31 to Int,
5193 which would otherwise raise Constraint_Error.
5195 2017-04-25 Bob Duff <duff@adacore.com>
5197 * opt.ads (Locking_Policy): Fix incorrect documentation. The
5198 first character of the policy name is not unique.
5200 2017-04-25 Bob Duff <duff@adacore.com>
5202 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
5203 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment

5221 Save and restore the value of global flag
5222 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

5224 the corresponding spec or the body must ignore all SPARK_Mode
5225 pragmas found within.
5226 (Analyze_Subprogram_Declaration): Mark
5227 the spec when it needs to ignore all SPARK_Mode pragmas found
5228 within to allow the body to infer this property in case it is
5229 instantiated or inlined later.
5230 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5231 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5232 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5233 when the corresponding spec also ignored all SPARK_Mode pragmas
5235 (Analyze_Package_Declaration): Mark the spec when
5236 it needs to ignore all SPARK_Mode pragmas found within to allow
5237 the body to infer this property in case it is instantiated or
5239 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
5240 Save and restore the value of flag
5241 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5242 formal 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.
5245 (Analyze_Package_Instantiation): Save and restore the value
5246 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
5247 the instance spec when it needs to ignore all SPARK_Mode

5266 Ignore_Pragma_SPARK_Mode.
5267 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5268 all SPARK_Mode pragmas defined within yields mode "off".
5270 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5272 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

5289 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5291 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5292 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5293 variable and set it to True whenever the main hash table is
5294 populated. Short- circuit the Assoc function if it is false
5295 and add associated guards.
5297 2017-04-25 Olivier Hainque <hainque@adacore.com>
5299 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5300 specs without elaboration code that have an elaboration counter
5301 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5302 * sem_ch10.adb (Analyze_Compilation_Unit):
5303 Set_Elaboration_Entity_Required when requested to preserve
5304 control flow, to ensure the unit elaboration is materialized at
5305 bind time, resulting in the inclusion of the unit object file
5306 in the executable closure at link time.
5308 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5310 * exp_dbug.adb: In Debug_Renaming_Declaration,
5311 when dealing with indexed component, accept to produce a renaming
5312 symbol when the index is an IN parameter or when it is a name
5313 defined in an outer scope.
5315 2017-04-25 Yannick Moy <moy@adacore.com>
5317 * errout.adb (Error_Msg): Adapt continuation
5318 message in instantiations and inlined bodies for info messages.
5320 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5322 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5323 Use direct 4-character slice comparisons.
5325 pragma Inline. (Has_Suffix): Delete.
5326 (Is_Internal_File_Name):
5327 Test Is_Predefined_File_Name first.
5328 (Is_Predefined_File_Name):
5329 Use direct slice comparisons as much as possible and limit all
5330 comparisons to at most 8 characters.
5332 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5334 * checks.adb (Insert_Valid_Check): Code cleanup.
5335 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5336 (Expand_Actuals): Generate proper copy-back for a validation
5337 variable when it acts as the argument of a type conversion.
5338 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5339 predicate to operate on type qualifications.
5341 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5343 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5346 2017-04-25 Bob Duff <duff@adacore.com>
5348 * sem_prag.adb (No_Return): Give an error if the pragma applies
5349 to a body. Specialize the error for the specless body case,
5350 as is done for (e.g.) pragma Convention.
5351 * debug.adb: Add switch -gnatd.J to disable the above legality
5352 checks. This is mainly for use in our test suite, to avoid
5353 rewriting a lot of illegal (but working) code. It might also
5354 be useful to customers. Under this switch, if a pragma No_Return
5355 applies to a body, and the procedure raises an exception (as it
5356 should), the pragma has no effect. If the procedure does return,
5357 execution is erroneous.
5359 2017-04-25 Bob Duff <duff@adacore.com>
5361 * exp_ch6.adb (Expand_Actuals): This is the
5362 root of the problem. It took N as an 'in out' parameter, and in
5363 some cases, rewrote N, but then set N to Original_Node(N). So
5364 the node returned in N had no Parent. The caller continued
5365 processing of this orphaned node. In some cases that caused a
5366 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5367 and trips over the Empty Parent). The solution is to make N an
5368 'in' parameter. Instead of rewriting it, return the list of
5369 post-call actions, so the caller can do the rewriting later,
5370 after N has been fully processed.
5371 (Expand_Call_Helper): Move most of Expand_Call here. It has
5372 too many premature 'return' statements, and we want to do the
5373 rewriting on return.
5374 (Insert_Post_Call_Actions): New procedure to insert the post-call
5375 actions in the appropriate place. In the problematic case,
5376 that involves rewriting N as an Expression_With_Actions.
5377 (Expand_Call): Call the new procedures Expand_Call_Helper and
5378 Insert_Post_Call_Actions.
5380 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5382 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5383 properly type derived from generic formal types, to handle
5384 properly modified version of ACATS 4.1B B611017.
5386 2017-04-25 Javier Miranda <miranda@adacore.com>
5388 * exp_unst.adb (Subp_Index): Adding missing
5389 support for renamings and functions that return a constrained
5390 array type (i.e. functions for which the frontend built a
5391 procedure with an extra out parameter).
5393 2017-04-25 Pascal Obry <obry@adacore.com>
5395 * s-string.adb: Minor code clean-up.
5397 2017-04-25 Bob Duff <duff@adacore.com>

5402 function for Non_Blocking_Wait_Process.
5404 2017-04-25 Bob Duff <duff@adacore.com>
5406 * prep.adb (Preprocess): Remove incorrect
5407 Assert. Current character can be ASCII.CR.
5409 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5411 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5412 convention Stdcall, which has a number of exceptions. Convention
5413 is legal on a component declaration whose type is an anonymous
5414 access to subprogram.
5416 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5418 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5419 (Try_One_Prefix_Interpretation): Use the base type when dealing
5420 with a subtype created for purposes of constraining a private
5421 type with discriminants.
5423 2017-04-25 Javier Miranda <miranda@adacore.com>
5425 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

5427 dispatching primitives (Restore_Warnings): Restore warning on
5428 late dispatching primitives (Save_Warnings): Save warning on late
5429 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5430 to enable/disable this warning.
5431 (WA_Warnings): Set warning on late dispatching primitives.
5432 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5433 that its parent type has a private extension.
5434 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5436 * usage.adb: Document -gnatw.j and -gnatw.J.
5438 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5440 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5443 2017-04-25 Bob Duff <duff@adacore.com>
5445 * binde.adb (Validate): Do not pass dynamic strings
5446 to pragma Assert, because older compilers do not support that.
5448 2017-04-25 Bob Duff <duff@adacore.com>
5450 * s-fileio.adb (Close): When a temp file is
5451 closed, delete it and clean up its Temp_File_Record immediately,
5452 rather than waiting until later.
5453 (Temp_File_Record): Add File
5454 component, so Close can know which Temp_File_Record corresponds
5455 to the file being closed.
5456 (Delete): Don't delete temp files,
5457 because they are deleted by Close.
5458 (Open): Set the File component
5459 of Temp_File_Record. This requires moving the creation of the
5460 Temp_File_Record to the end, after the AFCB has been created.
5462 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5464 * checks.adb (Insert_Valid_Check): Do not generate
5465 a validity check when inside a generic.

5479 concerning inheritance of class-wide preconditions do not apply
5482 2017-04-25 Bob Duff <duff@adacore.com>
5484 * s-ficobl.ads: Minor comment fix.
5486 2017-04-25 Yannick Moy <moy@adacore.com>
5488 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5489 conversions from float to integer in GNATprove mode.
5490 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5491 to call Apply_Type_Conversion_Checks, so that range checks
5492 are properly positioned when needed on conversions, including
5493 when converting from float to integer. (Determine_Range): In
5494 GNATprove mode, take into account the possibility of conversion
5495 from float to integer.
5496 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5497 check on conversions from fixed-point to integer, not anymore
5498 on conversions from floating-point to integer, when in GNATprove
5501 2017-04-25 Yannick Moy <moy@adacore.com>
5503 * checks.adb (Determine_Range_R): Special case type conversions
5504 from integer to float in order to get bounds in that case too.
5505 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5506 mode, for computations involved in interval checking.

5520 * exp_attr.adb (Make_Range_Test): Add processing for validation
5521 variables to avoid extra reads and copies of the prefix.
5522 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5523 variables in order to reflect any changes done in the variable
5524 back into the original object.
5525 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5526 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5534 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5536 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5537 Analyze_Pre_Post_Condition, to implement the legality checks
5538 mandated by AI12-0131: Pre'Class shall not be specified for an
5539 overriding primitive subprogram of a tagged type T unless the
5540 Pre'Class aspect is specified for the corresponding primitive
5541 subprogram of some ancestor of T.
5543 2017-04-25 Bob Duff <duff@adacore.com>
5545 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5546 is redundant, set its Used_Operations to empty. This is only
5547 necessary for use clauses that appear in the parent of a generic
5548 child unit, because those use clauses get reanalyzed when we
5549 instantiate the generic, and we don't want the Used_Operations
5550 carried over from the original context (where it was probably
5553 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5576 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5577 is True, then don't generate the accessibility check for the
5578 tag of a tagged result.
5579 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
5580 if CodePeer_Mode is True, then don't generate the
5581 tag checks for the result of call to an instance of
5582 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5583 descendant of" check and the accessibility check).

5594 (Expand_Concatenate): When optimization is enabled, also expand
5595 the operation out-of-line if the concatenation is present within
5596 the expression of the declaration of a library-level object and
5597 not only if it is the expression of the declaration.
5599 2017-04-25 Bob Duff <duff@adacore.com>
5601 * freeze.adb (Freeze_Object_Declaration): Do
5602 not Remove_Side_Effects if there is a pragma Linker_Section,
5603 because in that case we want static initialization in the
5604 appropriate section.
5606 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5608 * exp_dbug.adb: Minor rewording and reformatting.
5610 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5612 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5613 handle the proposed changes to rules concerning potentially

5637 renaming entity for debug information, mark the entity as needing debug
5638 info if it comes from sources.
5640 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5642 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

5661 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5662 internal calls that appear in preconditions of protected
5663 operations, in default values for same, and in contract guards
5664 for contract cases in SPARK.

5675 * a-numaux-x86.ads: Fix package description.
5676 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5677 (Reduce): Adjust and complete description. Call Is_Nan instead of
5678 testing manually. Use an integer temporary to hold rounded value.
5679 * a-numaux-darwin.adb (Reduce): Likewise.
5680 (Is_Nan): New function.
5682 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5684 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5685 on analysis of prefix whose type is a current instance of a
5686 synchronized type, but where the prefix itself is an entity that
5689 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5691 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5692 the identity of callable entities therein, because they have been
5693 properly resolved, and prefixed calls may have been rewritten
5696 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5698 * exp_ch3.adb (Build_Init_Statements): Convert
5699 the expression of the pragma/aspect Secondary_Stack_Size to

5712 * s-osinte-freebsd.ads: Minor comment tweaks
5714 2017-04-25 Javier Miranda <miranda@adacore.com>
5716 * urealp.adb (UR_Write): Reverse previous patch
5717 adding documentation on why we generate multiplications instead
5718 of divisions (needed to avoid expressions whose computation with
5719 large numbers may cause division by 0).
5721 2017-04-25 Bob Duff <duff@adacore.com>
5723 * erroutc.adb (Set_Specific_Warning_Off,
5724 Set_Warnings_Mode_Off): Use the correct source file for
5725 Stop. Was using Current_Source_File, which is only valid during
5726 parsing. Current_Source_File will have a leftover value from
5727 whatever file happened to be parsed last, because of a with_clause
5730 2017-04-25 Bob Duff <duff@adacore.com>
5732 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5733 to In_Predefined_Unit, but including GNAT units.
5734 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5735 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5736 because Should_Ignore_Pragma was not working reliably outside
5737 the parser, because Current_Source_File is not valid.
5738 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5739 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5776 Build_Invariant_Procedure_Body.
5777 (Build_Invariant_Procedure_Body):
5778 Remove refactored calls and integrated code from
5779 Add_Parent_Invariants and Add_Interface_Invariants.
5781 2017-04-25 Johannes Kanig <kanig@adacore.com>
5783 * errout.adb (Output_Messages): Adjust computation of total
5785 * erroutc.adb (Error_Msg): In statistics counts, deal
5786 correctly with informational messages that are not warnings.

5803 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5806 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5808 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5809 of prefix whose type is a current instance of a synchronized
5810 type. If the prefix is an object this is an external call (or
5811 requeue) that can only access public operations of the object. The
5812 previous predicate was too restrictive, and did not allow public
5813 protected operations, only task entries.
5815 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5817 * sem_ch5.adb, fname.adb: Minor reformatting.
5819 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5821 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5822 * einfo.ads Update the placement of
5823 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5825 (Is_Anonymous_Access_Type): New routine.
5826 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5827 master for an access type subject to pragma No_Heap_Finalization.
5828 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5829 allocated or deallocated does not finalization actions if the
5830 associated access type is subject to pragma No_Heap_Finalization.
5831 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5832 * par-prag.adb Pragma No_Heap_Finalization does not need special
5833 processing from the parser.
5834 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5835 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5836 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5837 No_Heap_Finalization.
5838 (Analyze_Pragma): Add processing for
5839 pragma No_Heap_Finalization. Update various error messages to
5840 use Duplication_Error.
5841 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5842 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5843 and corresponding pragma id.
5845 2017-04-25 Bob Duff <duff@adacore.com>
5847 * freeze.adb (Freeze_Record_Type): Use the
5848 underlying type of the component type to determine whether it's
5849 elementary. For representation clause purposes, a private type
5850 should behave the same as its full type.
5851 * fname.ads, fname.adb (Is_Predefined_File_Name):
5852 Make sure things like "system.ali" are recognized as predefined.
5854 2017-04-25 Javier Miranda <miranda@adacore.com>

5860 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5861 element iterator when the name is an overloaded function call,
5862 one of whose interpretations yields an array.
5864 2017-04-25 Bob Duff <duff@adacore.com>
5866 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5867 Is_Internal_Unit_Name): New functions for operating on unit
5868 names, as opposed to file names. There's some duplicated code
5869 with fname.adb, which is unfortunate, but it seems like we don't
5870 want to add dependencies here.
5871 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5872 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5873 is not a file name at all.
5874 * fname.ads, fname.adb: Document the fact that
5875 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5876 for ALI files, and fix the code so it works properly for ALI
5877 files. E.g. these should return True for "system.ali".
5879 2017-04-25 Justin Squirek <squirek@adacore.com>
5881 * exp_util.adb (Add_Invariant): Removed,
5882 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5883 and Add_Own_Invariant. (Add_Invariant_Check): Used
5884 for adding runtime checks from any kind of invariant.
5885 (Add_Inherited_Invariant): Generates invariant checks for
5886 class-wide invariants (Add_Interface_Invariants): Removed, code
5887 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5888 Create a types own invariant procedure (Add_Parent_Invariants):
5889 Removed, code moved to Build_Invariant_Procedure_Body
5890 (Build_Invariant_Procedure_Body): Add refactored calls
5891 and integrated code from Add_Parent_Invariants and
5892 Add_Interface_Invariants.
5893 (Process_Type): Removed, the
5894 relavant code was inlined into both Add_Own_Invariant and
5895 Add_Inherited_Invariant.
5897 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5899 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5916 and Build_Invariant_Procedure_Declaration.
5917 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5918 and Build_Invariant_Procedure_Declaration from exp_ch7
5919 and break-out Is_Untagged_Private_Derivation from
5920 Build_Invariant_Procedure_Body.
5921 (Replace_Type_References):
5922 Append an extra parameter to allow for dispatching replacements
5923 and add the corrasponding logic.
5924 (Type_Invariant): Remove
5925 Replace_Typ_Refs and replace its references with calls to
5926 Replace_Type_References.
5927 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5929 2017-04-25 Bob Duff <duff@adacore.com>
5931 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5932 that returns True when appropriate.
5933 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5934 when compiling predefined files.
5935 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5936 "gnat.adc" should not be considered a predefined file name.
5937 That required (or at least encouraged) a lot of cleanup of global
5938 variable usage. We shouldn't be communicating information via
5939 the global name buffer.
5940 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5941 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5961 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5962 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5963 Add String_To_Name with no side effects.
5965 2017-04-25 Justin Squirek <squirek@adacore.com>
5967 * sem_ch3.adb (Analyze_Declarations): Add
5968 additional condition for edge case.

5972 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5973 reserved words inside pragmas. This is necessary to allow the
5974 pragma name Interface to be used in pragma Ignore_Pragma.
5975 * par.adb: Minor comment fix.
5977 2017-04-25 Javier Miranda <miranda@adacore.com>
5979 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

6000 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
6001 the first pass over an assignment statement with target names,
6002 to prevent the generation of subtypes (such as discriminated
6003 record components)that may carry the target name outside of the
6004 tree for the assignment. The subtypes will be generated when
6005 the assignment is reanalyzed in full.
6006 (Analyze_Target_Name): Handle properly class-wide types.

6016 and resolve the triaged expression because all substitutions
6017 refer to the proper entities. Update the replacement of

6020 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6021 are now only processed when freezing occurs. Build a body only

6038 properties of the private type to the full view in case the full
6039 view derives from a parent type and inherits a DIC pragma.
6040 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6041 DIC pragma is placed at the top of a declarative region.
6043 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6045 * a-tasatt.adb: Complete previous change and use an unsigned
6046 int to avoid overflow checks.
6048 2017-04-25 Ed Schonberg <schonberg@adacore.com>

6051 the error message when the attribute reference is an actual in
6052 a call to a subprogram inherited from a generic formal type with
6053 unknown discriminants, which makes the subprogram and its formal
6054 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6056 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6058 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6063 * sem_attr.adb (Type_Key): Add code in the
6064 recursive Compute_Type_Key to protect against fetching the source
6065 code for Standard, in case a component of the type is declared
6066 in Standard. There was already code to do this for the original
6067 type, but not for its components.
6069 2017-04-25 Javier Miranda <miranda@adacore.com>
6071 * exp_ch3.adb (Build_Initialization_Call): Handle
6072 subtypes of private types when searching for the underlying full

6765 (Check_Dependency_Clause): Properly detect a match between two
6766 'Result attributes. Update the various post-match cases to use

6770 (Remove_Extra_Clauses): New routine.
6771 (Report_Extra_Clauses): Remove the detection of ... => null

6830 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6831 an object declaration for an array type with a modular index type
6832 with the size of Long_Long_Integer. Special processing is needed
6833 in this case to compute reliably the size of the object, and
6834 eventually to raise Storage_Error, when wrap-around arithmetic
6835 might compute a meangingless size for the object.
6837 2017-01-23 Justin Squirek <squirek@adacore.com>

6844 * sem_res.adb (Resolve_Call): In the part of the code where
6845 it is deciding whether to turn the call into an indexed
6846 component, avoid doing so if the call is to an instance of
6847 Unchecked_Conversion. Otherwise, the compiler turns it into an
6848 indexed component, and resolution of that turns it back into a
6849 function call, and so on, resulting in infinite recursion.
6850 * sem_util.adb (Needs_One_Actual): If the first formal has a
6851 default, then return False.

6898 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6899 must be treated as delayed aspect even if the expression is

6953 returns a limited view of a type and at the point of the call the
6954 function is not declared in the extended main unit then replace
6955 it with the non-limited view, which must be available. If the
6956 called function is in the extended main unit then no action is
6957 needed since the back-end handles this case.

6971 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6972 base type differs from that of the completion and the private
6973 subtype is an itype (created for a constraint on an access

7215 2017-01-19 Bob Duff <duff@adacore.com>
7217 * binde.adb, debug.adb: Enable new elaboration order algorithm
7218 by default. -dp switch reverts to the old algorithm.

7263 * exp_ch6.adb (Expand_Call): Remove side effects on
7264 actuals that are allocators with qualified expression since the
7265 initialization of the object is performed by means of individual
7266 statements (and hence it must be done before the call).

7270 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7271 (Build_Derived_Enumeration_Type): If the derived type inherits a
7272 dynamic predicate from its parent, the bounds of the type must
7273 freeze because an explicit constraint is constructed for the
7274 type and the corresponding range is elaborated now.

7327 these variables to be of subtype Nat instead of Int, because
7328 they should never be negative.

7359 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7361 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7362 selected component has a prefix that might be interpreted
7363 as a parameterless function call, but none of the candidate
7364 interpretations is parameterless, and there is a hidden homonym
7365 of the prefix that is a package.
7366 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7367 interpreted as a parameterless function call and its analysis
7368 fails, do not call Analyze_Selected_Component.
7370 2017-01-19 Steve Baird <baird@adacore.com>
7372 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7374 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7375 calls to a newly-defined Scalar_Range_Of_Right_View function.

7382 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7383 from repeated code of Traverse_Compilation_Unit.
7384 (Traverse_Declaration_Or_Statement): fixed detection of
7385 generic subprograms and packages; also, iteration over case
7386 statement alternatives rewritten to avoid testing if the first
7387 alternative is present (since it must be present due to Ada
7388 syntax restrictions).
7390 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7392 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as

7402 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
7403 identifier nodes that do not come from source, to handle properly
7404 dimensionality check within an inlined body which inclddes both
7405 original operands and rewritten operands. This removes spurious
7406 dimensionality errors in the presence of front-end inlining,
7407 as well as in SPARK mode.
7409 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7480 * sem_ch6.adb (Cloned_Expression): New subprogram.
7481 (Freeze_Expr_Types): Complete previous patch since the expression
7482 of an expression-function may have iterators and loops with
7483 defining identifiers which, as part of the preanalysis of the
7484 expression, may be left decorated with itypes that will not be
7485 available in the tree passed to the backend.
7487 2017-01-13 Ed Schonberg <schonberg@adacore.com>

7505 Ensure that the input body is a subprogram body before trying to
7506 determine whether it denoted an expression function. Note that
7507 subprogram body stubs cannot denote expression functions.
7509 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7525 2017-01-13 Bob Duff <duff@adacore.com>
7527 * binde.adb (Elab_New): New elaboration order algorithm
7528 that is expected to cause fewer ABE issues. This is a work in
7529 progress. The new algorithm is currently disabled, and can be
7530 enable by the -dp switch, or by modifying the Do_Old and Do_New
7531 etc. flags and rebuilding. Experimental code is included to
7532 compare the results of the old and new algorithms.
7533 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7534 can have multiple of these tables, so the old and new algorithms
7536 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7537 parameter of type array. This avoids the global variable, and
7538 allows bounds checking (which is normally defeated by the tables
7539 packages). It also ensures that the Elab_Order is read-only
7541 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7542 subprograms that need it, as above.
7543 * debug.adb: Document new -dp switch. Modify doc of old -do
7545 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7546 and Bindgen. Move writing of closure (-R and -Ra switches)

7551 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7552 function is a completion, all entities referenced in the
7553 expression are frozen. As a consequence, a reference to an
7554 uncompleted private type from an enclosing scope is illegal.
7556 2017-01-13 Javier Miranda <miranda@adacore.com>
7558 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7559 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7560 expression function declaration that is a completion, its
7561 expression causes freezing (AI12-0103).
7563 2017-01-13 Vadim Godunko <godunko@adacore.com>
7565 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7577 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7578 restriction No_Tasking is in effect.

7622 of the original association. Generate a loop even for a single
7623 component choice, in order to make loop parameter visible in
7625 (Flatten): An Iterated_Component_Association is not static.

7649 mode a choice that is a subtype with a static predicate is
7650 replaced by the values it covers. This transformation must not

7675 has a Discrete_Choices list, as specified in the RM. A
7676 Component_Association for aggregate uses instead a Choices list.
