335 2017-09-08 Yannick Moy <moy@adacore.com>
337 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
338 return the entity associated with the call.
339 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
340 Replace the internal Get_Function_Id with the new
341 Sem_Aux.Get_Called_Entity.
342 (Iterate_Call_Parameters): New
343 procedure to iterate on formals and actuals at the same time.
344 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
345 Set SPARK_Mode from spec when set, for analysis
346 of instance. Restore after analysis of instance.
347 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
348 set, for analysis of body instance. Restored automatically at
349 the end of the subprogram.
350 * gnat1drv.adb (Adjust_Global_Switches): Set
351 Check_Validity_Of_Parameters to False in GNATprove mode.
352 * opt.ads (Check_Validity_Of_Parameters): Document switch to
355 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
357 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
358 (New_Copy_Tree): ...there. Reset the hash tables only if they
359 were used in the previous invocation.
360 * s-htable.adb: Fix typo.
362 2017-09-08 Bob Duff <duff@adacore.com>
364 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
366 2017-09-08 Arnaud Charlet <charlet@adacore.com>
368 * sem_aggr.adb: minor style fix.
370 2017-09-08 Bob Duff <duff@adacore.com>
372 * sprint.adb (Write_Corresponding_Source): Ignore if there is
373 no current source file.
374 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
375 Print something helpful in case N is invalid.
376 * sprint.ads: Minor comment fix.
378 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
380 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
383 2017-09-08 Bob Duff <duff@adacore.com>
385 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
386 Ada_2020, along the same lines as the other Ada version pragmas.
388 2017-09-08 Gary Dismukes <dismukes@adacore.com>
390 * sem_ch12.adb: Minor typo fixes and reformatting.
392 2017-09-08 Yannick Moy <moy@adacore.com>
394 * sem_aggr.adb (Resolve_Record_Aggregate):
395 Rewrite bounds of aggregate subexpressions which may depend on
396 discriminants of the enclosing aggregate.
398 2017-09-08 Yannick Moy <moy@adacore.com>
400 * sem_ch5.adb: Prevent assertion failure on illegal code.
402 2017-09-08 Yannick Moy <moy@adacore.com>
404 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
405 calling Renamed_Entity on an entity which cannot be a renaming.
407 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
409 * exp_aggr.adb: Add with & use clause for Urealp.
410 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
411 elementary types instead of just discrete types.
412 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
413 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
414 Be prepared for the FP zero value in the memset case. Add small
417 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
419 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
422 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
424 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
425 of New_Copy because the latter leaves the syntactic structure of
426 the tree inconsistent (a child is accessible through two parents)
427 and prevents proper replication of itypes by subsequent calls
429 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
430 New_Copy because the latter leaves the syntactic structure of the
431 tree inconsistent (a child is accessible through two parents)
432 and prevents proper replication of itypes by subsequent calls
434 * sem_util.adb (In_Subtree): New routine.
435 (New_Copy_Tree): Reimplemented.

439 2017-09-08 Ed Schonberg <schonberg@adacore.com>
441 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
442 for aspect Default_Value is a static scalar value, but it does
443 not freeze the type. Yhis allows for subsequent representation
444 clauses for the type.
446 2017-09-08 Javier Miranda <miranda@adacore.com>
448 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
449 not add entries into the undefined reference table when we are
450 compiling with errors ignored.
452 2017-09-08 Ed Schonberg <schonberg@adacore.com>
454 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
455 check if the instance is within an enclosing instance body. The
456 formal package was legal in the enclosing generic, and is
457 legal in the enclosing instantiation. This optimisation may be
458 applicable elsewhere, and it also removes spurious errors that
459 may arise with on-the-fly processing of instantiations that
460 contain Inline_Always subprograms.
462 2017-09-08 Vincent Celier <celier@adacore.com>
464 * gnatcmd.adb: Disregard empty argument of GNAT driver.
466 2017-09-08 Justin Squirek <squirek@adacore.com>
468 * checks.adb (Insert_Valid_Check): Manually decorate
469 the generated temporary for range valdity checks.
471 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
473 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
475 2017-09-08 Justin Squirek <squirek@adacore.com>
477 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
478 case to handle underscore flags.
479 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
480 new procedure to handle underscores.
482 2017-09-08 Javier Miranda <miranda@adacore.com>
484 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
485 divisions with fixed point results to avoid generating twice
486 the runtime check on divide by zero.
487 * checks.adb (Apply_Divide_Checks): Ensure that operands are
488 not evaluated twice (once for their runtime checks and once for
489 their regular computation).
491 2017-09-08 Yannick Moy <moy@adacore.com>
493 * sem_prag.adb (Analyze_Part_Of): Add missing
494 return statements after issuing errors. Add detection of
495 out-of-order item and single concurrent type.

599 2017-09-08 Bob Duff <duff@adacore.com>
601 * s-ststop.ads, s-ststop.adb, rtsfind.ads (String_Input_Tag):
602 New routine to read the Tag robustly.

609 * s-rident.ads (Restriction_Id): reorder enum
610 literals, so that Pure_Barriers is no longer in range of the
611 Cunit_Boolean_Restrictions subtype.
613 2017-09-08 Nicolas Roche <roche@adacore.com>

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

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

820 access to interface types. Remove also the accessibility check.
822 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
824 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
825 all the types that are referenced by the expression.
826 (Analyze_Expression_Function): Call Freeze_Expr_Types for
827 a completion instead of manually freezing the type of the
829 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
831 2017-09-08 Ed Schonberg <schonberg@adacore.com>
833 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
834 New procedure, auxiliary to Expand_Pragma_Check, to handle
835 references to the discriminants of a protected type within a
836 precondition of a protected operation. This is needed because
837 the original precondition has been analyzed in the context of
838 the protected declaration, but in the body of the operation
839 references to the discriminants have been replaved by references
840 to the discriminants of the target object, and these references
841 are only created when expanding the protected body.
843 2017-09-08 Yannick Moy <moy@adacore.com>
845 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
848 2017-09-08 Ed Schonberg <schonberg@adacore.com>

851 unchecked union, do not emit checks for its (non-existent)
852 discriminants, or for variant parts that depend on them.
854 2017-09-08 Justin Squirek <squirek@adacore.com>
856 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
857 Find_Comparison_Type.Try_One_Interp): Add check for generic
860 2017-09-08 Arnaud Charlet <charlet@adacore.com>
862 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,

866 remaining references to AAMP_On_Target.
868 2017-09-08 Ed Schonberg <schonberg@adacore.com>

877 interfaces using the underlying type to handle limited-withed
879 (Attribute_Tag): Check class-wide type interfaces using
880 the underlying type to handle limited-withed types.
882 2017-09-08 Ed Schonberg <schonberg@adacore.com>
884 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
885 over a subtype of a type with a static predicate, taking into
886 account the predicate function of the parent type and the bounds
887 given in the loop specification.
888 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
889 a loop specification that is a subtype indication whose type mark
890 is a type with a static predicate, inherit predicate function,
891 used to build case statement for rewritten loop.
893 2017-09-08 Justin Squirek <squirek@adacore.com>
895 * lib-load.adb: Modify printing of error message to exclude file
898 2017-09-08 Arnaud Charlet <charlet@adacore.com>
900 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
901 don't inline subprograms declared in both visible and private
903 (In_Package_Spec): previously In_Package_Visible_Spec; now
904 detects subprograms declared both in visible and private parts
907 2017-09-08 Ed Schonberg <schonberg@adacore.com>
909 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
910 the type is an anonymous array in an object declaration, whose
911 component type has an invariant, use the object declaration
912 as the insertion point for the invariant procedure, given that
913 there is no explicit type declaration for an anonymous array type.
915 2017-09-08 Bob Duff <duff@adacore.com>
917 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
919 2017-09-08 Bob Duff <duff@adacore.com>
921 * a-strfix.adb (Trim): Compute Low and High only if needed.
923 2017-09-08 Justin Squirek <squirek@adacore.com>
925 * lib-load.adb (Load_Main_Source): Add error output in the case a
926 source file is missing.
928 2017-09-08 Bob Duff <duff@adacore.com>
931 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
932 Default_WCEM by default (i.e. if the encoding is not specified
935 2017-09-08 Bob Duff <duff@adacore.com>
937 * s-trasym.ads (Hexa_Traceback): If
938 Suppress_Hex is True, print "..." instead of a hexadecimal
940 * s-trasym.adb: Ignore No_Hex in this version.
943 2017-09-08 Bob Duff <duff@adacore.com>
945 * debug.adb: Minor reformatting.
947 2017-09-08 Bob Duff <duff@adacore.com>
949 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
950 code so it doesn't trigger an "uninit var" warning.

954 * s-hibaen.ads: Remove obsolete file.
956 2017-09-08 Arnaud Charlet <charlet@adacore.com>

960 2017-09-08 Arnaud Charlet <charlet@adacore.com>
962 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
964 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
965 allow calls in the context of package spec (for pragma
966 Initializes) and bodies (for pragma Refined_State).
968 2017-09-08 Bob Duff <duff@adacore.com>

973 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
975 * debug.adb (dA): Adjust comment.
976 * gnat1drv.adb (Gnat1drv): Likewise.
977 * opt.ads (List_Representation_Info_Extended): New variable.
978 * repinfo.adb (List_Record_Info): Split implementation into...
979 (Compute_Max_Length): ...this. Recurse on records if requested.
980 (List_Record_Layout): Likewise.
981 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
982 statement, accept '0' and set List_Representation_Info_Extended
984 * usage.adb (Usage): Document new -gnatRe variant.
986 2017-09-08 Ed Schonberg <schonberg@adacore.com>
988 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
989 Do not save the given entity in the global variable Default_Pool
990 if the pragma appears within a generic unit.
992 2017-09-08 Bob Duff <duff@adacore.com>
994 * errout.adb (Delete_Warning): Do not
995 decrement Warnings_Treated_As_Errors. This is called before
996 Warnings_Treated_As_Errors has been incremented to account for
997 this warning. Decrementing it here can lead to negative values
998 of Warnings_Treated_As_Errors, raising Constraint_Error in
999 checks-on builds, and causing the compiler to return an error
1000 code in checks-off builds.
1002 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1004 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
1005 entities of named concurrent types as Ref_Id and not of anonymous
1006 concurrent objects (because callers already know when a conversion
1007 is necessary and can easily do it); also, do not expect protected
1008 types or protected objects as Context_Id (because no flow-related
1009 SPARK pragmas are attached there); reflect these changes in a
1010 more precise comment.
1012 2017-09-08 Olivier Hainque <hainque@adacore.com>
1014 * g-altive.ads: Add documentation.
1016 2017-09-08 Bob Duff <duff@adacore.com>
1018 * sem_util.ads, debug.adb: Minor comment fix.
1019 * erroutc.ads: Comment fix.
1021 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1023 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
1024 for compatibility of component types of formal and actual in an
1025 instantiation of a child unit, when the component type of the
1026 formal is itself a formal of an enclosing generic.
1028 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1030 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1031 sem_prag.adb to make it available for GNATprove; for concurrent
1032 types replace custom scope climbing with Scope_Same_Or_Within; for
1033 single concurrent objects add scope climbing (with Scope_Within),
1034 which was not there (that's the primary semantic change of this
1035 commit); also, when comparing a single concurrent object with
1036 its corresponding concurrent type rely on equality of types,
1037 not of objects (because that's simpler to code).
1038 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1039 (Analyze_Global_Item): adjust special-casing of references to the
1040 current instance of a concurrent unit in the Global contracts
1041 of task types and single tasks objects; similar for references
1042 in the protected operations and entries of protected types and
1043 single protected objects (in all these cases the current instance
1044 behaves as an implicit parameter and must not be mentioned in
1045 the Global contract).
1047 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1049 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1050 function calls returning a record within a subprogram call,
1053 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1055 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded

1585 Add missing implicit type conversion to force displacement of the
1588 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
1590 * sem_ch3.adb, sem_aux.adb, sem_res.adb: Minor reformatting.
1592 2017-09-06 Yannick Moy <moy@adacore.com>
1594 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
1595 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
1597 2017-09-06 Bob Duff <duff@adacore.com>
1599 * sem_ch8.adb: Change Assert to be consistent with
1602 2017-09-06 Bob Duff <duff@adacore.com>
1604 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1605 requested. Previously, the -do switch meant "run Elab_New and
1606 Elab_Old and use the order chosen by Elab_Old, possibly with
1607 debugging printouts comparing the two orders." Now it means
1608 "do not run Elab_New." This is of use if there are bugs that
1609 cause Elab_New to crash.
1610 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1612 * ali.ads (Elab_Position): Change type to Nat, to avoid various
1615 2017-09-06 Arnaud Charlet <charlet@adacore.com>
1617 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
1618 reference to SPARK RM.
1620 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1622 * layout.adb: Use SSU short hand consistently throughout the file.
1624 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1626 * freeze.adb (Freeze_Record_Type)
1627 <Sized_Component_Total_Round_RM_Size>: New local variable to
1628 accumulate the rounded RM_Size of components. Update it for
1629 every component whose RM_Size is statically known. Add missing
1630 guard to check that bit packing is really required before issuing
1631 the error about packing. Swap condition for clarity's sake.
1632 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

1651 project manager sources.
1653 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1655 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1656 entity of a mutable type and the right-hand side is a conditional
1657 expression, resolve the alternatives of the conditional using
1658 the base type of the target entity, because the alternatives
1659 may have distinct subtypes. This is particularly relevant if
1660 the alternatives are aggregates.
1662 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1664 * checks.adb (Apply_Predicate_Check): If the expression is an
1665 aggregate that is the RHS of an assignment, apply the check to
1666 the LHS after the assignment, rather than to the aggregate. This
1667 is more efficient than creating a temporary for the aggregate,
1668 and prevents back-end crashes when the aggregate includes a
1669 dynamic "others' association.
1671 2017-09-06 Yannick Moy <moy@adacore.com>
1673 * sem_ch12.adb (Analyze_Instance_And_Renamings):

1681 seen and is candidate for inlining.

1685 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

1687 body. do not freeze the formals of the generic unit.
1689 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1691 * errout.adb (Error_Msg): Separate the
1692 treatment for warning vs. style messages in inlinings and
1693 instantiations. Prevents blowups on calls to Warn_Insertion for
1694 style messages, which should not be called in that case because
1695 Warning_Msg_Char is not set.
1697 2017-09-06 Justin Squirek <squirek@adacore.com>
1699 * sem_prag.adb (Check_VFA_Conflicts): Created
1700 to group all Volatile_Full_Access checks relating to other
1701 representation pragmas (Mark_Component_Or_Object): Created
1702 to centeralize the flagging of attributes for the record type
1703 component case, a pragma applied individually to a component, and
1705 (Process_Atomic_Independent_Shared_Volatile):
1706 Add propagation of certain pragmas to record components and move

1720 2017-09-06 Bob Duff <duff@adacore.com>
1722 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1723 that is a proper body corresponding to a stub, we defer the
1724 adjustment of the sloc until after the correct adjustment has
1725 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1726 the adjustment, because it will be outside the range in (the old,
1727 incorrect) S_Adjustment.
1728 * inline.adb: Use named notation for readability and uniformity.

1800 the actual is declared in the same unit and has a corresponding
1801 body, to prevent the current instance from being frozen before

1826 missing case of controlled generalized indexing.
1827 (Is_Source_Object): Use routine Strip to remove indirections.
1828 (Strip): New routine.
1830 2017-09-06 Bob Duff <duff@adacore.com>
1832 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1833 we include the proper header. Otherwise, we just declare the necessary
1834 things from the capabilities library. This is so we can build on
1835 machines without that library, while still enabling that library.
1836 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1837 simply return 0 if the library is not present, or not included

1853 has no parameter specification and no entry index, use the entry name
1854 as the end of the generated SCO statement.
1856 2017-09-06 Steve Baird <baird@adacore.com>
1858 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1859 uses of 'Image and related attributes as having side effects in
1860 order to avoid replicating such uses.
1861 * pprint.ads (Expression_Image) Add new generic formal flag
1862 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1863 (eventually) override the default.
1864 * pprint.adb (Expression_Image) If the new flag is set, then
1865 suppress the ".all" suffix when displaying a dereference whose
1866 prefix is a use of a value-capturing compiler temp of the sort
1867 generated by Expr_Util.Remove_Side_Effects .

1883 so that applies to any entity.
1885 2017-09-06 Yannick Moy <moy@adacore.com>
1887 * sem_ch3.adb (Derived_Type_Declaration): Use
1888 Incomplete_Or_Partial_View rather than local Find_Partial_View.
1890 2017-09-06 Javier Miranda <miranda@adacore.com>
1892 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
1895 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1897 * sem_dim.adb (Analyze_Dimension): In an instance, a type

1900 (Dimensions_Of_Operand): Ditto.
1902 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1904 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

1925 2017-09-06 Yannick Moy <moy@adacore.com>
1927 * freeze.adb (Check_Inherited_Conditions): Rewriting
1928 of inherited preconditions and postconditions should only occur
1929 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1930 be confused with SPARK_Mode being On.

1947 (Entity_Table_Size): New constant.
1948 (Entity_Hash): New function.
1949 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1950 (Is_Subprogram_Ref): Rename into...
1951 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1952 the table instead of bailing out on them. Scan the value of constants
1953 if it is not known at compile time.
1954 (Contains_Subprograms_Refs): Rename into...
1955 (Scan_Subprogram_Refs): ...this.
1956 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1957 Is_Public flag on subprograms if they are not actually referenced.
1958 (Hide_Public_Entities): Beef up comment on the algorithm.
1959 Reset the table of subprograms on entry.

2015 2017-09-06 Bob Duff <duff@adacore.com>
2017 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
2018 check back to the body, because SPARK is not yet ready for

2046 * sem_type.adb (Interface_Present_In_Ancestor): Within an
2047 expression function, or within a spec expression (default value,
2048 etc) a reference to an incomplete type is legal: legality of
2049 the operation will be checked when some related entity (type,
2050 object or subprogram) is frozen.
2052 2017-09-06 Gary Dismukes <dismukes@adacore.com>
2054 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

2065 * a-comlin.ads, a-comlin.adb (Argument): Simplify the code, now that
2066 we can use modern Ada in this package.
2067 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2068 Move Ada.Command_Line.Response_File to System.Response_File,
2069 and make Ada.Command_Line.Response_File into a rename of
2070 System.Response_File. This is to avoid having gnatbind depend
2071 Ada.Command_Line, which would damage the bootstrap process now
2072 that Ada.Command_Line contains modern Ada (the raise expression).
2073 * gnatbind.adb: Avoid dependence on
2074 Ada.Command_Line. Depend on System.Response_File instead

2213 of the right-hand side has stored constraint, use its values
2214 (except for those that are renamings of parent discriminants)
2215 to produce additional assignments for the discriminants of the
2216 left-hand side, which are invisible in the righ-hand side and
2217 not retrievable as selected components.
2219 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2221 * sem_util.adb (Needs_One_Formal): The first formal of such a

2260 constraint for it, given that the constrained discriminants are
2261 not visible in the object.
2262 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2263 side may be derived from that of the left-hand side (as in the
2264 case of an assignment with a change of representation) so the
2265 discriminant to be used in the retrieval of the value of the
2266 component must be the entity in the type of the right-hand side.

2295 in a set membership is an overloaded enumeration literal, and
2296 the type of the alternative is resolved from a previous one,
2297 replace the entity of the alternative as well as the type,
2298 to prevent inconsistencies between the entity and the type.

2841 * exp_ch6.adb (Expand_Call_Helper): When locating the
2842 accessibility entity created for an access parameter, handle
2843 properly a reference to a formal of an enclosing subprogram. if
2844 the reference appears in an inherited class-wide condition, it
2845 is the rewriting of the reference in the ancestor expression,
2846 but the accessibility entity must be that of the current formal.

2886 procedure body for a local (sub)type declaration within a
2887 predicate function. Invariant checks do not apply to these, and
2888 the expansion of the procedure will happen in the wrong scope,
2889 leading to misplaced freeze nodes.
2891 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2893 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2894 to analyze generated actions. If the main unit is a body,

2930 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2931 Refine predicate for the case where the primitive operation
2932 is a renaming of equality. An overriding operation that is
2933 a user-defined renaming of predefined equality inherits its
2934 slot from the overridden operation. Otherwise it is treated
2935 as a predefined op and occupies the same predefined slot as
2936 equality. A call to it is transformed into a call to its alias,
2937 which is the predefined equality. A dispatching call thus uses
2938 the proper slot if operation is further inherited and called
2939 with class-wide arguments.

2943 * errout.adb (Set_Msg_Text): Add a case to switch the message

2976 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2977 statement if the initialization call is a null procedure, as
2978 can happen with a controlled type with no explicit Initialize
2979 procedure, or an array of such.

2981 controlled components that has a trivial Initialize procedure,
2982 insert declaration for finalization counter after object

3018 2017-05-02 Gary Dismukes <dismukes@adacore.com>
3020 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
3021 parameter Array_Comp to indicate the case of an array object
3022 with null-excluding components.
3023 * checks.adb (Null_Exclusion_Static_Checks):
3024 Call Compile_Time_Constraint_Error instead of
3025 Apply_Compile_Time_Constraint_Error in the component case. Also
3026 call that when Array_Comp is True, with an appropriate warning for
3027 the array component case. Only create an explicit initialization
3028 by null in the case of an object of a null-excluding access type
3029 (and no longer do that in the component case).
3030 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3031 Array_Comp defaulted to False. Pass Empty for the Comp
3032 actual when calling Null_Exclusion_Static_Checks in the case
3033 where Comp_Decl matches Object_Decl, because we don't have a
3034 component in that case. In the case of an object or component
3035 of an array type, pass True for Array_Comp on the recursive call

3040 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3041 compute the linux priority from the Ada priority. Call this everywhere
3042 required. In particular, the previous version was not doing this
3043 computation when setting the ceiling priority in various places. It
3044 was just converting to C.int, which results in a ceiling that is off
3047 2017-05-02 Ed Schonberg <schonberg@adacore.com>

3065 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
3066 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3067 here from exp_ch9, to recognize objects whose creation requires
3068 dynamic allocation, so that the proper warning can be emitted
3069 when restriction No_Implicit_Heap_Allocation is in effect.
3070 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
3071 to emit proper warning when an object that requires dynamic
3072 allocation is declared.
3074 2017-05-02 Tristan Gingold <gingold@adacore.com>
3076 * s-trasym.ads, s-trasym.adb (Enable_Cache): New.
3078 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3080 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
3081 visibility rules for equality operators that apply within an
3082 instantiation apply within an inlined body.
3083 * sem_type.adb (Add_One_Interp): ditto.
3085 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3087 * sem_prag.adb (Analyze_Pragma): Forbid pragma Contract_Cases on null
3090 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3093 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
3094 Name_No_Tagged_Streams): Move to regular pragmas. Add
3095 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
3096 and Secondary_Stack_Size.
3097 (Pragma_Id): Move Pragma_Assume,
3098 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
3099 Pragma_No_Tagged_Streams to second part.

3108 detection for illegal references to private components or
3109 operations of a protected type in the body of the type.
3111 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3113 * opt.ads: Add missing GNAT markers in comments.
3114 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
3115 settings of Optimize_Alignment at the end.
3117 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3119 * checks.adb (Apply_Constraint_Check): Do not apply
3120 a discriminant check when the associated type is a constrained
3121 subtype created for an unconstrained nominal type.
3122 * exp_attr.adb: Minor reformatting.
3124 2017-05-02 Bob Duff <duff@adacore.com>

3136 operator /= into negation of operator = when needed.
3137 (Expand_SPARK): Call new
3138 function to expand operator /=.
3140 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3142 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3143 Simplify the expression for a fixed-fixed division to remove
3144 divisions by constants whenever possible, as an optimization
3145 for restricted targets.
3147 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3149 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3151 2017-05-02 Bob Duff <duff@adacore.com>
3153 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3154 to find primitive ops, instead of using an Identifier that will
3155 later be looked up. This is necessary because these ops are not
3156 necessarily visible at all places where we need to call them.
3157 * exp_util.ads: Minor comment fix.
3159 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3161 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3162 references are fully conformant if they are both expansions
3163 of the discriminant of a protected type, within one of the
3164 protected operations. One occurrence may be expanded into a
3165 constant declaration while the other is an input parameter to
3166 the corresponding generated subprogram.
3168 2017-05-02 Justin Squirek <squirek@adacore.com>
3170 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3171 recursivly searching composite-types for null-excluding access
3172 types and verifying them.
3173 (Analyze_Object_Declaration): Add a
3174 call to Check_Null_Excluding_Components for static verification
3175 of non-initialized objects.
3176 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3177 a parameter for a composite-type's component and an extra case
3178 for printing component information.
3180 2017-05-02 Yannick Moy <moy@adacore.com>
3182 * sem_ch10.adb (Analyze_Subunit): Take
3183 configuration pragma into account when restoring appropriate
3184 pragma for analysis of subunit.
3186 2017-05-02 Justin Squirek <squirek@adacore.com>
3188 * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
3189 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
3190 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
3191 clauses from the runtime.
3193 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3195 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
3196 array components specially.
3198 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3200 * sem_ch8.adb (Premature_Usage): If the premature usage of
3201 an entity is as the expression in its own object decaration,
3202 rewrite the reference as Any_Id to prevent cascaded errors or
3203 compiler loops when such an entity is used in an address clause.
3205 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3207 * gcc-interface/decl.c (components_to_record): Add missing guard.
3209 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3211 * gcc-interface/decl.c (components_to_record): Add more comments.
3212 Put back pending fields onto the regular list if the misalignment
3213 happens to cancel itself.
3215 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3217 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3218 controlling actual in a prefixed call, preserve the original node
3219 information if the prefix itself has been rewritten, for ASIS use.
3221 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3223 * exp_ch6.adb (Insert_Post_Call_Actions):
3224 Code clean up. Insert the post-call actions after an enclosing
3225 procedure call when N denotes a function call and appears as an
3226 actual parameter in the procedure call.
3228 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3230 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3231 for the component, also reject the attribute if the component
3232 doesn't end on a byte boundary and its scalar storage order is
3233 different from that of the enclosing record type.
3235 2017-04-28 Javier Miranda <miranda@adacore.com>
3237 * atree.ads (Info_Messages): Removed.
3238 (Warning_Info_Messages): New counter.
3239 (Report_Info_Messages): New counter.

3255 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3257 * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.

3267 2017-04-28 Bob Duff <duff@adacore.com>
3269 * sem_util.ads, sem_util.adb (Might_Raise): New function
3270 that replaces Is_Exception_Safe, but has the opposite
3271 sense. Is_Exception_Safe was missing various cases -- calls inside
3272 a pragma Debug, calls inside an 'if' or assignment statement,
3273 etc. Might_Raise now walks the entire subtree looking for things
3275 * exp_ch9.adb (Is_Exception_Safe): Remove.
3276 (Build_Protected_Subprogram_Body): Replace call to
3277 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3278 constants where possible).
3279 * exp_ch7.adb: Rename Is_Protected_Body -->
3280 Is_Protected_Subp_Body. A protected_body is something different
3283 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3285 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.
3286 * par-ch3.adb (P_Component_Items): Initialize Decl_Node variable.

3303 * checks.adb (Install_Primitive_Elaboration_Check):
3304 Do not generate an elaboration check if all checks have been
3307 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3309 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3310 Interrupt_Handler and Attach_Handler): Generate reference
3311 to protected operation to prevent spurious warnings about
3312 unreferenced entities. Previous scheme failed with style checks
3315 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3317 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3318 that follows an expression function must not be relocated to
3319 the generated body, because it applies to the code that follows.
3321 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3323 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3324 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3325 code that might violate the more stringent checking for 'Access
3326 introduced in Ada 2005.
3328 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3330 * a-cforse.adb: minor style fix in comment.
3332 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3334 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3335 initialize Block_Decls variable.
3336 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3337 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
3338 * exp_disp.adb (Expand_Interface_Actuals): Initialize
3339 Formal_DDT and Actual_DDT variables.
3340 (Expand_Interface_Thunk): Initialize Iface_Formal.
3341 (Make_DT): Initialize Size_Comp.
3342 (Make_Select_Specific_Data_Table): Initialize Decls.

3346 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3348 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3350 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3351 node between access types, freeze the designated type as well,
3352 so that dispatch table pointers are created in the proper scope,
3353 and not in the constructed body of the expression function.
3355 2017-04-28 Bob Duff <duff@adacore.com>
3357 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3358 value makes large compilations faster, but small compilations slower.
3360 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3362 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3364 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3366 * erroutc.adb (Compilation_Errors): Do not consider info messages
3367 as suitable warnings when warnings must be treated as errors.
3368 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3369 internally-generated packages when outputting completion
3371 * errout.adb (Output_Messages): Do not consider info messages as
3372 suitable warnings when warnings must be treated as errors.

3374 suitable warnings when warnings must be treated as errors.
3376 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3378 * warnsw.ads: Minor fix for incorrect wording in comment.
3380 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3382 * sem_res.adb (In_Instance_Code): New predicate in
3383 Valid_Conversion, to determine whether a type conversion appears
3384 as (or within) an actual for a formal object. Type conversions
3385 in instances are not rechecked in Valid_Conversion because
3386 visibility changes between generic location andi instance may
3387 lead to spurious errors, but conversions within an actual must be
3388 fully checked, and they are not fully resolved when pre-analyzing
3391 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3393 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3394 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3395 of the relocated node will have mangled Parent pointers.
3396 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3397 tables used in conjunction with entity and itype replication.
3398 (Visit_Entity): Rewrite the restriction on which entities
3399 require duplication. The restriction now includes all types.
3401 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3403 * a-cofuse.ads, a-cfdlli.ads, a-cfhase.adb, a-cfhase.ads, a-cfinve.adb,

3417 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3419 * sem_ch4.adb: Fix copy/pasto.
3421 2017-04-27 Tristan Gingold <gingold@adacore.com>
3423 * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
3424 raise-gcc.c. Fix include search path for raise-gcc.c
3426 2017-04-27 Eric Botcazou <ebotcazou@adacore.com>
3428 * fe.h (Warn_On_Questionable_Layout): Declare.
3429 * warnsw.ads (Warn_On_Record_Holes): Move down.
3430 (Warn_On_Questionable_Layout): New boolean variable.
3431 (Warning_Record): Add Warn_On_Questionable_Layout field.
3432 * warnsw.adb (All_Warnings): Set Warn_On_Questionable_Layout.
3433 (Restore_Warnings): Likewise.
3434 (Save_Warnings): Likewise.
3435 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3436 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3437 components_to_record.
3438 (gnu_field_to_gnat): New function.
3439 (warn_on_field_placement): Likewise.
3440 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3441 parameters. Rename local variables and adjust recursive call.
3442 Rework final scan of the field list and implement warnings on the
3443 problematic placement of specific sorts of fields.
3445 2017-04-27 Bob Duff <duff@adacore.com>
3447 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,
3448 * fname.ads, freeze.adb, inline.adb, lib.adb, lib.ads, lib-list.adb,
3449 * lib-load.adb, lib-writ.adb, par.adb, restrict.adb, rtsfind.adb,

3451 * sem_ch4.adb, sem_ch6.adb, sem_ch8.adb, sem_ch9.adb, sem_elab.adb,
3452 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3453 For efficiency, cache results of Is_Internal_File_Name and
3454 Is_Predefined_File_Name in the Units table. This avoids a lot
3455 of repeated text processing.
3457 2017-04-27 Emmanuel Briot <briot@adacore.com>
3459 * g-comlin.adb (Sort_Sections): remove useless test.
3461 2017-04-27 Claire Dross <dross@adacore.com>
3463 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3464 allow the use of regular equality over elements in contracts.
3465 (Formal_Model): Ghost package containing model functions that are
3466 used in subprogram contracts.
3467 (Current_To_Last): Removed, model functions should be used instead.
3468 (First_To_Previous): Removed, model functions should be used instead.
3469 (Strict_Equal): Removed, model functions should be used instead.
3470 (No_Overlap): Removed, model functions should be used instead.
3471 (Equivalent_Keys): Functions over cursors are removed. They were
3472 awkward with explicit container parameters.
3473 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3474 allow the use of regular equality over elements in contracts.
3475 (Formal_Model): Ghost package containing model functions that
3476 are used in subprogram contracts.
3477 (Current_To_Last): Removed, model functions should be used instead.
3478 (First_To_Previous): Removed, model functions should be used instead.
3479 (Strict_Equal): Removed, model functions should be used instead.
3480 (No_Overlap): Removed, model functions should be used instead.
3482 2017-04-27 Yannick Moy <moy@adacore.com>
3484 * gnat1drv.adb: Code cleanup.
3486 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3488 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3489 attribute reference in a post- condition is the subprogram to
3490 which the condition applies. If the condition is inherited
3491 by a type extension, the prefix becomes a reference to the
3492 inherited operation, but there is no need to create a wrapper
3493 for this operation, because 'Result is expanded independently
3494 when elaborating the postconditions.
3496 2017-04-27 Bob Duff <duff@adacore.com>
3498 * sinput.adb: Minor code cleanup.
3499 * namet.adb (Append): Create faster versions of
3500 Append(String) and Append(Name_Id) by using slice assignment
3502 * sem_util.adb (In_Instance): Speed this up by removing
3503 unnecessary tests; Is_Generic_Instance is defined for all
3505 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3506 Remove unused function.
3507 * alloc.ads (Nodes_Initial): Use a much larger value, because
3508 the compiler was spending a lot of time copying the nodes table
3509 when it grows. This number was chosen in 1996, so is rather out
3510 of date with current memory sizes. Anyway, it's virtual memory.
3511 Get rid of Orig_Nodes_...; use Node_... instead.
3512 * atree.adb (Lock): Do not release the Nodes tables; it's a
3514 Orig_Nodes_ ==> Nodes_
3515 * nlists.adb: Orig_Nodes_ ==> Nodes_
3516 * g-table.adb: Remove unused "with" clause.
3517 * g-table.ads, table.ads: Remove Big_Table_Type, which should
3518 not be used by clients.
3519 * g-dyntab.adb (Last_Allocated): New function
3520 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
3522 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3524 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
3526 (Subtypes_Statically_Match): Remove duplicate check.
3527 * sem_prag.adb (Check_Arg_Is_External_Name): Remove duplicate check.
3529 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3531 * exp_aggr.adb (Replace_Type): Remove the special processing
3532 for selected components.
3533 * exp_attr.adb (Expand_N_Attribute_Reference): Merge the
3534 processing for attributes Fixed_Value and Integer_Value.
3535 * exp_util.adb (Side_Effect_Free): Merge the processing for

3541 tokens function, not, overriding, and procedure.
3542 * sem_ch6.adb (Fully_Conformant_Expressions): Merge the processing
3543 for qualified expressions, type conversions, and unchecked
3545 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
3546 processing for Ada 83 and instances.
3547 (Object_Access_Level): Merge the processing for indexed components
3548 and selected components.

4090 modifications in functional containers.
4091 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4092 to improve readablity. Subprograms are separated between basic
4093 operations, constructors and properties. Universally quantified
4094 formulas in contracts are factorized in independant functions
4095 with a name and a comment. Names of parameters are improved.
4097 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4099 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
4101 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4103 * sem_res.adb (Resolve_Type_Conversion): Do not
4104 install a predicate check here since this is already done during
4105 the expansion phase. Verify whether the operand satisfies the
4106 static predicate (if any) of the target type.
4107 * sem_ch3.adb (Analyze_Object_Declaration): Do
4108 not install a predicate check if the object is initialized by
4109 means of a type conversion because the conversion is subjected

4134 in gnat1 and gnatbind.
4135 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
4136 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

4144 modifications in functional containers.
4145 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4146 to improve readablity. Subprograms are separated between basic
4147 operations, constructors and properties. Universally quantified
4148 formulas in contracts are factorized in independant functions
4149 with a name and a comment. Names of parameters are improved.
4151 2017-04-27 Gary Dismukes <dismukes@adacore.com>

4183 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4185 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4186 the loop which detects potential enclosing transient scopes. The
4187 loop now terminates much earlier as transient scopes are bounded
4188 by packages and subprograms.
4190 2017-04-27 Claire Dross <dross@adacore.com>
4192 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4193 allow the use of regular equality over elements in contracts.
4194 (Cursor): Type is now public so that it can be used in
4196 (Formal_Model): Ghost package containing
4197 model functions that are used in subprogram contracts.
4198 (Current_To_Last): Removed, model functions should be used
4200 (First_To_Previous): Removed, model functions should
4202 (Strict_Equal): Removed, model functions
4203 should be used instead.
4204 (Append): Default parameter value
4205 replaced by new wrapper to allow more precise contracts.

4224 elaboration checks umbrella.
4226 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

4247 * debug.adb Change the documentation of switch -gnatd.s.
4248 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4249 to manage the secondary stack when an enclosing scope already
4250 performs this functionality (aka relaxed management). Switch
4251 -gnatd.s may be used to force strict management in which case
4252 the block will manage the secondary stack unconditionally. Add
4253 a guard to stop the traversal when encountering a package or a
4256 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4258 * sem_res.adb (Resolve_Call): Refine further the handling of
4259 limited views of return types in function calls. If the function
4260 that returns a limited view appears in the current unit,
4261 we do not replace its type by the non-limited view because
4262 this transformation is performed int the back-end. However,
4263 the type of the call itself must be the non-limited view, to
4264 prevent spurious resolution errors.
4266 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4268 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4269 Removed, proposed implementation using generics for class-wide
4270 preconditions proved impractical.
4271 (Class_Wide_Clone): New attribute of subprogram. Designates
4272 subprogram created for primitive operations with class-wide
4273 pre/postconditions that contain calls to other primitives. The
4274 clone holds the body of the original primitive, but the
4275 pre/postonditions do not apply to it. The original body is
4276 rewritten as a wrapper for a call to the clone.
4277 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4278 the flag is set, no code for the corresponding pre/postconditions
4279 is inserted into its body.
4281 2017-04-27 Bob Duff <duff@adacore.com>
4283 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

4294 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
4295 (Remove): New function that removes an element from a set.
4296 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
4297 (Remove): New function that removes an element from a sequence.
4298 (Insert): New function that adds anywhere in a sequence.

4311 of attribute 'Result is not considered a violation of pragma
4314 2017-04-27 Justin Squirek <squirek@adacore.com>
4316 * cstand.adb (Create_Standard): Correctly set

4327 private child of Ada.Containers used to implement all functional
4329 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4330 child of Ada.Containers. It provides functional indefinite unbounded
4331 maps which can be used as high level models for specification
4333 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4334 child of Ada.Containers. It provides functional indefinite unbounded
4335 sets which can be used as high level models for specification
4337 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4338 child of Ada.Containers. It provides functional indefinite unbounded
4339 vectors which can be used as high level models for specification
4341 * Makefile.rtl: Add new packages.
4342 * impunit.adb: Add new packages.
4344 2017-04-27 Gary Dismukes <dismukes@adacore.com>

4348 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4350 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4351 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4352 point type actual that has user-defined arithmetic primitives,
4353 when there is a previous actual for a formal package that defines
4354 a fixed-point type with the parent user-defined operator.
4356 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4358 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4359 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4360 the component type allows range checks.
4362 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4364 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4365 corresponding declaration, because formal derived types are
4366 rewritten as private extensions.
4368 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4370 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4371 dimensions of operands if node has been analyzed already, because
4372 previous analysis and dimension checking will have removed the
4373 dimension information from the operands.
4375 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4377 * debug.adb: Document the use of switch -gnatd.s.
4378 * einfo.ads Update the documentation on attribute
4379 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4380 the uses of these attributes from certain entities.

4382 which determines whether the block should continue to manage
4383 the secondary stack.

4439 Ada_2012 instead of Ada_2005 to be compatible with the above
4441 * bindgen.adb: Silence new warning on pragma Ada_95.
4443 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4445 * checks.adb (Generate_Range_Check): Revert part of previous change.

4451 parameter association in a procedure call.
4453 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
4455 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
4456 Fix spelling mistakes.
4458 2017-04-25 Bob Duff <duff@adacore.com>
4460 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4461 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4462 for source buffers. Fix misc obscure bugs.
4463 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4464 checking, for source buffers. Modify representation clause for
4465 Source_File_Record as appropriate. Move Source_File_Index_Table
4466 from spec to body, because it is not used outside the body.
4467 Move Set_Source_File_Index_Table into the private part, because
4468 it is used only in the body and in children. Use trickery to
4469 modify the dope in the generic instantiation case. It's ugly,
4470 but not as ugly as the previous method. Fix documentation.
4471 Remove obsolete code.
4472 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
4473 indexing in source buffers.

4487 expander is not active or when index/range checks are suppressed
4489 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4490 Remove variants that include a Supress parameter. These routines
4491 are never used, and were introduced before the current scope-based
4492 check suppression method.
4494 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

4513 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
4514 is now carried out by Null_Status.
4515 (Null_Status): New routine.

4522 error on the return type of an expression function that is a
4523 completion, if the type is derived from a generic formal type.
4525 2017-04-25 Ed Schonberg <schonberg@adacore.com>

4542 errout.adb, sinput.adb, sinput.ads, cstand.adb, scn.adb,
4543 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
4544 the Internal_Source buffer. This removes the incorrect call to "="
4545 the customer noticed.
4546 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4547 eventually need to eliminate them altogether. Or else get rid
4548 of zero-origin addressing.
4550 2017-04-25 Claire Dross <dross@adacore.com>
4552 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New

5068 to the change made to Freeze_Type in exp_ch3. Add a condition
5069 to treat interface types as a partial view.
5070 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
5071 to Build_Invariant_Procedure_Declaration to properly generate a
5072 "partial" invariant procedure when Typ is an interface.
5074 2017-04-25 Bob Duff <duff@adacore.com>
5076 * a-numeri.ads: Go back to using brackets encoding for the Greek
5079 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5081 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5082 (10-15): if derived type T with progenitors is abstract,
5083 and primitive P of this type inherits non-trivial classwide
5084 preconditions from both a parent operation and from an interface
5085 operation, then the inherited operation is abstract if the parent
5086 operation is not null.
5087 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5088 with Covered_Interface_Op to yield the actual interface operation
5089 that is implemented by a given inherited operation.
5091 2017-04-25 Javier Miranda <miranda@adacore.com>
5093 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
5094 and right operands after performing the validity checks. Required
5095 because validity checks may remove side effects from the operands.
5097 2017-04-25 Javier Miranda <miranda@adacore.com>
5099 * exp_attr.adb (Attribute_Unrestricted_Access):
5100 Do not disable implicit type conversion. Required to generate
5101 code that displaces the pointer to reference the secondary

5112 values, and comparing them must use Expr_Value_S.
5114 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5116 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5117 dereference is introduced for the object, and the object is
5118 overloaded, do not check whether it is aliased, because it may
5119 include an implicit dereference.
5120 * sem_type.adb (Disambiguate): If two interpretations are access
5121 attribute types with the same designated type keep either of
5122 them and do not report an ambiguity. A true ambiguity will be
5125 2017-04-25 Bob Duff <duff@adacore.com>
5127 * a-numeri.ads: Change the encoding of Greek letter Pi from
5128 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5129 to indicate the encoding. We considered using a byte order mark
5130 (BOM), but that causes various trouble (misc software eats the
5131 BOM, if you have a patch with a BOM, then it's not at the start
5132 of the patch, so it's not a BOM, the BOM affects with-ing files,
5134 * scng.adb, s-wchcnv.adb: Minor.

5146 moved here from sem_ch3.
5147 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
5148 check given in RM 6.1.1 (17) concerning renamings of overriding
5149 operations that inherits class-wide preconditions from ancestor

5170 restrictions when the handler is internally generated and the
5173 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5175 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
5176 enforce legality rule on classwide preconditions inherited from
5177 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5178 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5179 subprogram need not be dispatching if it appears in a precondition
5180 for an abstract or null subprogram.
5182 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5184 * sem_ch10.adb: Minor typo fix.
5186 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5188 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
5190 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5192 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
5193 have a length which is a power of 2.
5194 (Is_Predefined_File_Name): Likewise. Adjust comment.
5196 2017-04-25 Bob Duff <duff@adacore.com>
5198 * exp_aggr.adb (Component_Count): Protect the
5199 arithmetic from attempting to convert a value >= 2**31 to Int,
5200 which would otherwise raise Constraint_Error.
5202 2017-04-25 Bob Duff <duff@adacore.com>
5204 * opt.ads (Locking_Policy): Fix incorrect documentation. The
5205 first character of the policy name is not unique.
5207 2017-04-25 Bob Duff <duff@adacore.com>
5209 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
5210 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment

5228 Save and restore the value of global flag
5229 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

5231 the corresponding spec or the body must ignore all SPARK_Mode
5232 pragmas found within.
5233 (Analyze_Subprogram_Declaration): Mark
5234 the spec when it needs to ignore all SPARK_Mode pragmas found
5235 within to allow the body to infer this property in case it is
5236 instantiated or inlined later.
5237 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5238 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5239 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5240 when the corresponding spec also ignored all SPARK_Mode pragmas
5242 (Analyze_Package_Declaration): Mark the spec when
5243 it needs to ignore all SPARK_Mode pragmas found within to allow
5244 the body to infer this property in case it is instantiated or
5246 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
5247 Save and restore the value of flag
5248 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5249 formal spec when it needs to ignore all SPARK_Mode
5250 pragmas found within to allow the body to infer this
5251 property in case it is instantiated or inlined later.
5252 (Analyze_Package_Instantiation): Save and restore the value
5253 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
5254 the instance spec when it needs to ignore all SPARK_Mode

5258 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5259 instance spec and anonymous package when they need to ignore
5260 all SPARK_Mode pragmas found within to allow the body to infer

5273 Ignore_Pragma_SPARK_Mode.
5274 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5275 all SPARK_Mode pragmas defined within yields mode "off".
5277 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5279 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

5296 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5298 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5299 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5300 variable and set it to True whenever the main hash table is
5301 populated. Short- circuit the Assoc function if it is false
5302 and add associated guards.
5304 2017-04-25 Olivier Hainque <hainque@adacore.com>
5306 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5307 specs without elaboration code that have an elaboration counter
5308 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5309 * sem_ch10.adb (Analyze_Compilation_Unit):
5310 Set_Elaboration_Entity_Required when requested to preserve
5311 control flow, to ensure the unit elaboration is materialized at
5312 bind time, resulting in the inclusion of the unit object file
5313 in the executable closure at link time.
5315 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5317 * exp_dbug.adb: In Debug_Renaming_Declaration,
5318 when dealing with indexed component, accept to produce a renaming
5319 symbol when the index is an IN parameter or when it is a name
5320 defined in an outer scope.
5322 2017-04-25 Yannick Moy <moy@adacore.com>
5324 * errout.adb (Error_Msg): Adapt continuation
5325 message in instantiations and inlined bodies for info messages.
5327 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5329 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5330 Use direct 4-character slice comparisons.
5332 pragma Inline. (Has_Suffix): Delete.
5333 (Is_Internal_File_Name):
5334 Test Is_Predefined_File_Name first.
5335 (Is_Predefined_File_Name):

5339 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5341 * checks.adb (Insert_Valid_Check): Code cleanup.
5342 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5343 (Expand_Actuals): Generate proper copy-back for a validation
5344 variable when it acts as the argument of a type conversion.
5345 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5346 predicate to operate on type qualifications.
5348 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5350 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5353 2017-04-25 Bob Duff <duff@adacore.com>
5355 * sem_prag.adb (No_Return): Give an error if the pragma applies
5356 to a body. Specialize the error for the specless body case,
5357 as is done for (e.g.) pragma Convention.
5358 * debug.adb: Add switch -gnatd.J to disable the above legality
5359 checks. This is mainly for use in our test suite, to avoid
5360 rewriting a lot of illegal (but working) code. It might also
5361 be useful to customers. Under this switch, if a pragma No_Return
5362 applies to a body, and the procedure raises an exception (as it
5363 should), the pragma has no effect. If the procedure does return,
5364 execution is erroneous.
5366 2017-04-25 Bob Duff <duff@adacore.com>
5368 * exp_ch6.adb (Expand_Actuals): This is the
5369 root of the problem. It took N as an 'in out' parameter, and in
5370 some cases, rewrote N, but then set N to Original_Node(N). So
5371 the node returned in N had no Parent. The caller continued
5372 processing of this orphaned node. In some cases that caused a
5373 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5374 and trips over the Empty Parent). The solution is to make N an
5375 'in' parameter. Instead of rewriting it, return the list of
5376 post-call actions, so the caller can do the rewriting later,
5377 after N has been fully processed.
5378 (Expand_Call_Helper): Move most of Expand_Call here. It has
5379 too many premature 'return' statements, and we want to do the
5380 rewriting on return.
5381 (Insert_Post_Call_Actions): New procedure to insert the post-call
5382 actions in the appropriate place. In the problematic case,
5383 that involves rewriting N as an Expression_With_Actions.
5384 (Expand_Call): Call the new procedures Expand_Call_Helper and
5385 Insert_Post_Call_Actions.
5387 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5389 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5390 properly type derived from generic formal types, to handle
5391 properly modified version of ACATS 4.1B B611017.
5393 2017-04-25 Javier Miranda <miranda@adacore.com>
5395 * exp_unst.adb (Subp_Index): Adding missing
5396 support for renamings and functions that return a constrained
5397 array type (i.e. functions for which the frontend built a
5398 procedure with an extra out parameter).
5400 2017-04-25 Pascal Obry <obry@adacore.com>
5402 * s-string.adb: Minor code clean-up.
5404 2017-04-25 Bob Duff <duff@adacore.com>

5411 2017-04-25 Bob Duff <duff@adacore.com>
5413 * prep.adb (Preprocess): Remove incorrect
5414 Assert. Current character can be ASCII.CR.
5416 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5418 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5419 convention Stdcall, which has a number of exceptions. Convention
5420 is legal on a component declaration whose type is an anonymous
5421 access to subprogram.
5423 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5425 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5426 (Try_One_Prefix_Interpretation): Use the base type when dealing
5427 with a subtype created for purposes of constraining a private
5428 type with discriminants.
5430 2017-04-25 Javier Miranda <miranda@adacore.com>
5432 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

5434 dispatching primitives (Restore_Warnings): Restore warning on
5435 late dispatching primitives (Save_Warnings): Save warning on late
5436 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5437 to enable/disable this warning.
5438 (WA_Warnings): Set warning on late dispatching primitives.
5439 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5440 that its parent type has a private extension.
5441 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5443 * usage.adb: Document -gnatw.j and -gnatw.J.
5445 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5447 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5450 2017-04-25 Bob Duff <duff@adacore.com>
5452 * binde.adb (Validate): Do not pass dynamic strings
5453 to pragma Assert, because older compilers do not support that.
5455 2017-04-25 Bob Duff <duff@adacore.com>
5457 * s-fileio.adb (Close): When a temp file is
5458 closed, delete it and clean up its Temp_File_Record immediately,
5459 rather than waiting until later.
5460 (Temp_File_Record): Add File
5461 component, so Close can know which Temp_File_Record corresponds
5462 to the file being closed.
5463 (Delete): Don't delete temp files,
5464 because they are deleted by Close.
5465 (Open): Set the File component
5466 of Temp_File_Record. This requires moving the creation of the
5467 Temp_File_Record to the end, after the AFCB has been created.
5469 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5471 * checks.adb (Insert_Valid_Check): Do not generate
5472 a validity check when inside a generic.

5486 concerning inheritance of class-wide preconditions do not apply
5489 2017-04-25 Bob Duff <duff@adacore.com>
5491 * s-ficobl.ads: Minor comment fix.
5493 2017-04-25 Yannick Moy <moy@adacore.com>
5495 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5496 conversions from float to integer in GNATprove mode.
5497 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5498 to call Apply_Type_Conversion_Checks, so that range checks
5499 are properly positioned when needed on conversions, including
5500 when converting from float to integer. (Determine_Range): In
5501 GNATprove mode, take into account the possibility of conversion
5502 from float to integer.
5503 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5504 check on conversions from fixed-point to integer, not anymore
5505 on conversions from floating-point to integer, when in GNATprove
5508 2017-04-25 Yannick Moy <moy@adacore.com>
5510 * checks.adb (Determine_Range_R): Special case type conversions
5511 from integer to float in order to get bounds in that case too.
5512 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5513 mode, for computations involved in interval checking.

5527 * exp_attr.adb (Make_Range_Test): Add processing for validation
5528 variables to avoid extra reads and copies of the prefix.
5529 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
5530 variables in order to reflect any changes done in the variable
5531 back into the original object.
5532 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
5533 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

5539 generate Finalize_Address routines for CodePeer.
5541 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5543 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
5544 Analyze_Pre_Post_Condition, to implement the legality checks
5545 mandated by AI12-0131: Pre'Class shall not be specified for an
5546 overriding primitive subprogram of a tagged type T unless the
5547 Pre'Class aspect is specified for the corresponding primitive
5548 subprogram of some ancestor of T.
5550 2017-04-25 Bob Duff <duff@adacore.com>
5552 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5553 is redundant, set its Used_Operations to empty. This is only
5554 necessary for use clauses that appear in the parent of a generic
5555 child unit, because those use clauses get reanalyzed when we
5556 instantiate the generic, and we don't want the Used_Operations
5557 carried over from the original context (where it was probably
5560 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5575 * sem_ch8.adb (Find_Type): For an attribute reference
5576 'Class, if prefix type is synchronized and previous errors

5583 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5584 is True, then don't generate the accessibility check for the
5585 tag of a tagged result.
5586 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
5587 if CodePeer_Mode is True, then don't generate the
5588 tag checks for the result of call to an instance of
5589 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5590 descendant of" check and the accessibility check).

5600 * exp_ch4.adb (Library_Level_Target): New function.
5601 (Expand_Concatenate): When optimization is enabled, also expand
5602 the operation out-of-line if the concatenation is present within
5603 the expression of the declaration of a library-level object and
5604 not only if it is the expression of the declaration.
5606 2017-04-25 Bob Duff <duff@adacore.com>
5608 * freeze.adb (Freeze_Object_Declaration): Do
5609 not Remove_Side_Effects if there is a pragma Linker_Section,
5610 because in that case we want static initialization in the
5611 appropriate section.
5613 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5615 * exp_dbug.adb: Minor rewording and reformatting.
5617 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5619 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5620 handle the proposed changes to rules concerning potentially
5621 unevaluated expressions, to include selected components that
5622 do not depend on discriminants, and indexed components with
5624 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5625 predicate in quantified expression, and fix bugs in the handling
5626 of case expressions and membership test.

5630 2017-04-25 Bob Duff <duff@adacore.com>
5632 * s-secsta.adb (SS_Info): Add a comment
5633 explaining why we don't need to walk all the chunks in order to
5634 compute the total size.
5636 2017-04-25 Bob Duff <duff@adacore.com>
5638 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length

5644 renaming entity for debug information, mark the entity as needing debug
5645 info if it comes from sources.
5647 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5649 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
5650 restriction converning the use of 'Address where the prefix is
5651 of a controlled type.
5653 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5655 * exp_dbug.adb: In Debug_Renaming_Declaration,
5656 skip slices that are made redundant by an indexed component

5664 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5666 * sem_ch3.adb (Check_Entry_Contract): Call
5667 Preanalyze_Spec_Expression so that resolution takes place as well.
5668 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5669 internal calls that appear in preconditions of protected
5670 operations, in default values for same, and in contract guards
5671 for contract cases in SPARK.
5673 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5675 * a-numaux.ads: Fix description of a-numaux-darwin
5677 (Double): Define to Long_Float.
5678 * a-numaux-vxworks.ads (Double): Likewise.
5679 * a-numaux-darwin.ads
5681 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
5682 * a-numaux-x86.ads: Fix package description.
5683 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5684 (Reduce): Adjust and complete description. Call Is_Nan instead of
5685 testing manually. Use an integer temporary to hold rounded value.
5686 * a-numaux-darwin.adb (Reduce): Likewise.
5687 (Is_Nan): New function.
5689 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5691 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5692 on analysis of prefix whose type is a current instance of a
5693 synchronized type, but where the prefix itself is an entity that
5696 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5698 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5699 the identity of callable entities therein, because they have been
5700 properly resolved, and prefixed calls may have been rewritten
5703 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5705 * exp_ch3.adb (Build_Init_Statements): Convert
5706 the expression of the pragma/aspect Secondary_Stack_Size to
5707 internal type System.Parameters.Size_Type before assigning
5708 it to the Secondary_Stack_Size component of the task type's
5709 corresponding record.
5711 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5713 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
5714 (etc) optimizations when the type is modular and the offsets
5717 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5719 * s-osinte-freebsd.ads: Minor comment tweaks
5721 2017-04-25 Javier Miranda <miranda@adacore.com>
5723 * urealp.adb (UR_Write): Reverse previous patch
5724 adding documentation on why we generate multiplications instead
5725 of divisions (needed to avoid expressions whose computation with
5726 large numbers may cause division by 0).
5728 2017-04-25 Bob Duff <duff@adacore.com>
5730 * erroutc.adb (Set_Specific_Warning_Off,
5731 Set_Warnings_Mode_Off): Use the correct source file for
5732 Stop. Was using Current_Source_File, which is only valid during
5733 parsing. Current_Source_File will have a leftover value from
5734 whatever file happened to be parsed last, because of a with_clause
5737 2017-04-25 Bob Duff <duff@adacore.com>
5739 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5740 to In_Predefined_Unit, but including GNAT units.
5741 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5742 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5743 because Should_Ignore_Pragma was not working reliably outside
5744 the parser, because Current_Source_File is not valid.
5745 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5746 * par-prag.adb: Call Should_Ignore_Pragma_Par.
5748 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
5750 * gnat1drv.adb (Gnat1Drv): Disable Generate_Processed_File in

5776 attempt evaluation of relational operations inside assertions.
5778 2017-04-25 Justin Squirek <squirek@adacore.com>
5780 * exp_util.adb (Add_Interface_Invariants):
5781 Restored, code moved back from Build_Invariant_Procedure_Body.
5782 (Add_Parent_Invariants): Restored, code moved back from
5783 Build_Invariant_Procedure_Body.
5784 (Build_Invariant_Procedure_Body):
5785 Remove refactored calls and integrated code from
5786 Add_Parent_Invariants and Add_Interface_Invariants.
5788 2017-04-25 Johannes Kanig <kanig@adacore.com>
5790 * errout.adb (Output_Messages): Adjust computation of total
5792 * erroutc.adb (Error_Msg): In statistics counts, deal
5793 correctly with informational messages that are not warnings.
5794 * errutil.adb (Finalize): adjust computation of total errors.
5796 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

5805 2017-04-25 Justin Squirek <squirek@adacore.com>
5807 * sem_ch3.adb (Analyze_Declarations): Minor
5808 correction to comments, move out large conditional and scope
5809 traversal into a predicate.
5810 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5813 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5815 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5816 of prefix whose type is a current instance of a synchronized
5817 type. If the prefix is an object this is an external call (or
5818 requeue) that can only access public operations of the object. The
5819 previous predicate was too restrictive, and did not allow public
5820 protected operations, only task entries.
5822 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5824 * sem_ch5.adb, fname.adb: Minor reformatting.
5826 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5828 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5829 * einfo.ads Update the placement of
5830 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5832 (Is_Anonymous_Access_Type): New routine.
5833 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5834 master for an access type subject to pragma No_Heap_Finalization.
5835 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5836 allocated or deallocated does not finalization actions if the
5837 associated access type is subject to pragma No_Heap_Finalization.
5838 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5839 * par-prag.adb Pragma No_Heap_Finalization does not need special
5840 processing from the parser.
5841 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5842 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5843 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5844 No_Heap_Finalization.
5845 (Analyze_Pragma): Add processing for
5846 pragma No_Heap_Finalization. Update various error messages to
5847 use Duplication_Error.
5848 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5849 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5850 and corresponding pragma id.
5852 2017-04-25 Bob Duff <duff@adacore.com>
5854 * freeze.adb (Freeze_Record_Type): Use the
5855 underlying type of the component type to determine whether it's
5856 elementary. For representation clause purposes, a private type
5857 should behave the same as its full type.
5858 * fname.ads, fname.adb (Is_Predefined_File_Name):
5859 Make sure things like "system.ali" are recognized as predefined.
5861 2017-04-25 Javier Miranda <miranda@adacore.com>
5863 * debug.adb: Update documentation of -gnatd.6.
5865 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5867 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5868 element iterator when the name is an overloaded function call,
5869 one of whose interpretations yields an array.
5871 2017-04-25 Bob Duff <duff@adacore.com>
5873 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5874 Is_Internal_Unit_Name): New functions for operating on unit
5875 names, as opposed to file names. There's some duplicated code
5876 with fname.adb, which is unfortunate, but it seems like we don't
5877 want to add dependencies here.
5878 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5879 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5880 is not a file name at all.
5881 * fname.ads, fname.adb: Document the fact that
5882 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5883 for ALI files, and fix the code so it works properly for ALI
5884 files. E.g. these should return True for "system.ali".
5886 2017-04-25 Justin Squirek <squirek@adacore.com>
5888 * exp_util.adb (Add_Invariant): Removed,
5889 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5890 and Add_Own_Invariant. (Add_Invariant_Check): Used
5891 for adding runtime checks from any kind of invariant.
5892 (Add_Inherited_Invariant): Generates invariant checks for
5893 class-wide invariants (Add_Interface_Invariants): Removed, code
5894 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5895 Create a types own invariant procedure (Add_Parent_Invariants):
5896 Removed, code moved to Build_Invariant_Procedure_Body
5897 (Build_Invariant_Procedure_Body): Add refactored calls
5898 and integrated code from Add_Parent_Invariants and
5899 Add_Interface_Invariants.
5900 (Process_Type): Removed, the
5901 relavant code was inlined into both Add_Own_Invariant and
5902 Add_Inherited_Invariant.
5904 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5906 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5923 and Build_Invariant_Procedure_Declaration.
5924 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5925 and Build_Invariant_Procedure_Declaration from exp_ch7
5926 and break-out Is_Untagged_Private_Derivation from
5927 Build_Invariant_Procedure_Body.
5928 (Replace_Type_References):
5929 Append an extra parameter to allow for dispatching replacements
5930 and add the corrasponding logic.
5931 (Type_Invariant): Remove
5932 Replace_Typ_Refs and replace its references with calls to
5933 Replace_Type_References.
5934 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5936 2017-04-25 Bob Duff <duff@adacore.com>
5938 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5939 that returns True when appropriate.
5940 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5941 when compiling predefined files.
5942 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5943 "gnat.adc" should not be considered a predefined file name.
5944 That required (or at least encouraged) a lot of cleanup of global
5945 variable usage. We shouldn't be communicating information via
5946 the global name buffer.
5947 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5948 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5953 * osint.adb (Find_File): Handle properly a request for a
5954 configuration file whose name is a directory.

5965 2017-04-25 Bob Duff <duff@adacore.com>
5967 * sem_prag.adb: Remove suspicious uses of Name_Buf.
5968 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5969 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5970 Add String_To_Name with no side effects.
5972 2017-04-25 Justin Squirek <squirek@adacore.com>
5974 * sem_ch3.adb (Analyze_Declarations): Add
5975 additional condition for edge case.
5977 2017-04-25 Bob Duff <duff@adacore.com>
5979 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5980 reserved words inside pragmas. This is necessary to allow the
5981 pragma name Interface to be used in pragma Ignore_Pragma.
5982 * par.adb: Minor comment fix.
5984 2017-04-25 Javier Miranda <miranda@adacore.com>
5986 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.
5987 * rtsfind.ads (RE_Type_Is_Abstract): Renamed as Is_Abstract.

6007 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
6008 the first pass over an assignment statement with target names,
6009 to prevent the generation of subtypes (such as discriminated
6010 record components)that may carry the target name outside of the
6011 tree for the assignment. The subtypes will be generated when
6012 the assignment is reanalyzed in full.
6013 (Analyze_Target_Name): Handle properly class-wide types.
6015 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

6023 and resolve the triaged expression because all substitutions
6024 refer to the proper entities. Update the replacement of
6026 (Build_DIC_Procedure_Body): Add formal parameter
6027 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6028 are now only processed when freezing occurs. Build a body only

6032 (Replace_Object_And_Primitive_References): Removed.
6033 (Replace_References): New routine.

6045 properties of the private type to the full view in case the full
6046 view derives from a parent type and inherits a DIC pragma.
6047 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6048 DIC pragma is placed at the top of a declarative region.
6050 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
6052 * a-tasatt.adb: Complete previous change and use an unsigned
6053 int to avoid overflow checks.
6055 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6057 * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
6058 the error message when the attribute reference is an actual in
6059 a call to a subprogram inherited from a generic formal type with
6060 unknown discriminants, which makes the subprogram and its formal
6061 parameters intrinsic (see RM 6.3.1 (8) and (13)).
6063 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6065 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6068 2017-04-25 Bob Duff <duff@adacore.com>
6070 * sem_attr.adb (Type_Key): Add code in the
6071 recursive Compute_Type_Key to protect against fetching the source
6072 code for Standard, in case a component of the type is declared

6772 (Check_Dependency_Clause): Properly detect a match between two
6773 'Result attributes. Update the various post-match cases to use

6777 (Remove_Extra_Clauses): New routine.
6778 (Report_Extra_Clauses): Remove the detection of ... => null

6837 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6838 an object declaration for an array type with a modular index type
6839 with the size of Long_Long_Integer. Special processing is needed
6840 in this case to compute reliably the size of the object, and
6841 eventually to raise Storage_Error, when wrap-around arithmetic
6842 might compute a meangingless size for the object.
6844 2017-01-23 Justin Squirek <squirek@adacore.com>

6851 * sem_res.adb (Resolve_Call): In the part of the code where
6852 it is deciding whether to turn the call into an indexed
6853 component, avoid doing so if the call is to an instance of
6854 Unchecked_Conversion. Otherwise, the compiler turns it into an
6855 indexed component, and resolution of that turns it back into a
6856 function call, and so on, resulting in infinite recursion.
6857 * sem_util.adb (Needs_One_Actual): If the first formal has a
6858 default, then return False.

6903 2017-01-20 Ed Schonberg <schonberg@adacore.com>
6905 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6906 must be treated as delayed aspect even if the expression is

6929 the prefix is not null) when the prefix denotes an object of an
6930 access type; that is, when there is an implicit dereference.

6960 returns a limited view of a type and at the point of the call the
6961 function is not declared in the extended main unit then replace
6962 it with the non-limited view, which must be available. If the
6963 called function is in the extended main unit then no action is
6964 needed since the back-end handles this case.

6978 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6979 base type differs from that of the completion and the private
6980 subtype is an itype (created for a constraint on an access

7220 type may be required in an enclosing operation.
7222 2017-01-19 Bob Duff <duff@adacore.com>
7224 * binde.adb, debug.adb: Enable new elaboration order algorithm
7225 by default. -dp switch reverts to the old algorithm.

7270 * exp_ch6.adb (Expand_Call): Remove side effects on
7271 actuals that are allocators with qualified expression since the
7272 initialization of the object is performed by means of individual
7273 statements (and hence it must be done before the call).

7277 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
7278 (Build_Derived_Enumeration_Type): If the derived type inherits a
7279 dynamic predicate from its parent, the bounds of the type must
7280 freeze because an explicit constraint is constructed for the
7281 type and the corresponding range is elaborated now.

7334 these variables to be of subtype Nat instead of Int, because
7335 they should never be negative.

7366 2017-01-19 Ed Schonberg <schonberg@adacore.com>
7368 * sem_ch4.adb (Diagnose_Call): Improve error message when a
7369 selected component has a prefix that might be interpreted
7370 as a parameterless function call, but none of the candidate
7371 interpretations is parameterless, and there is a hidden homonym
7372 of the prefix that is a package.
7373 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
7374 interpreted as a parameterless function call and its analysis
7375 fails, do not call Analyze_Selected_Component.
7377 2017-01-19 Steve Baird <baird@adacore.com>
7379 * sem_util.ads: Add new Use_Full_View Boolean parameter to
7381 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
7382 calls to a newly-defined Scalar_Range_Of_Right_View function.

7389 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
7390 from repeated code of Traverse_Compilation_Unit.
7391 (Traverse_Declaration_Or_Statement): fixed detection of
7392 generic subprograms and packages; also, iteration over case
7393 statement alternatives rewritten to avoid testing if the first
7394 alternative is present (since it must be present due to Ada
7395 syntax restrictions).
7397 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
7399 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as

7410 identifier nodes that do not come from source, to handle properly
7411 dimensionality check within an inlined body which inclddes both
7412 original operands and rewritten operands. This removes spurious
7413 dimensionality errors in the presence of front-end inlining,
7414 as well as in SPARK mode.
7416 2017-01-16 Jakub Jelinek <jakub@redhat.com>

7455 * scil_ll.adb: Minor style fix in comment.
7456 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
7457 even if entity is already set, because the node may be renalyzed
7458 after inlining transformations.
7460 2017-01-13 Javier Miranda <miranda@adacore.com>
7462 * sem_res.adb (Resolve_Call): Do not establish a transient scope

7487 * sem_ch6.adb (Cloned_Expression): New subprogram.
7488 (Freeze_Expr_Types): Complete previous patch since the expression
7489 of an expression-function may have iterators and loops with
7490 defining identifiers which, as part of the preanalysis of the
7491 expression, may be left decorated with itypes that will not be
7492 available in the tree passed to the backend.
7494 2017-01-13 Ed Schonberg <schonberg@adacore.com>

7497 conversion to Integer of an expression that is an attribute
7498 reference 'Pos on an enumeration type.

7509 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
7511 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
7512 Ensure that the input body is a subprogram body before trying to
7513 determine whether it denoted an expression function. Note that
7514 subprogram body stubs cannot denote expression functions.
7516 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7532 2017-01-13 Bob Duff <duff@adacore.com>
7534 * binde.adb (Elab_New): New elaboration order algorithm
7535 that is expected to cause fewer ABE issues. This is a work in
7536 progress. The new algorithm is currently disabled, and can be
7537 enable by the -dp switch, or by modifying the Do_Old and Do_New
7538 etc. flags and rebuilding. Experimental code is included to
7539 compare the results of the old and new algorithms.
7540 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7541 can have multiple of these tables, so the old and new algorithms
7543 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7544 parameter of type array. This avoids the global variable, and
7545 allows bounds checking (which is normally defeated by the tables
7546 packages). It also ensures that the Elab_Order is read-only
7548 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7549 subprograms that need it, as above.
7550 * debug.adb: Document new -dp switch. Modify doc of old -do
7552 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7553 and Bindgen. Move writing of closure (-R and -Ra switches)
7554 to Binde; that's more convenient.
7556 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7558 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7559 function is a completion, all entities referenced in the
7560 expression are frozen. As a consequence, a reference to an
7561 uncompleted private type from an enclosing scope is illegal.
7563 2017-01-13 Javier Miranda <miranda@adacore.com>
7565 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7566 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7567 expression function declaration that is a completion, its
7568 expression causes freezing (AI12-0103).
7570 2017-01-13 Vadim Godunko <godunko@adacore.com>
7572 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7656 mode a choice that is a subtype with a static predicate is
7657 replaced by the values it covers. This transformation must not
7658 be performed in ASIS mode, to preserve the source for analysis.

7682 has a Discrete_Choices list, as specified in the RM. A
7683 Component_Association for aggregate uses instead a Choices list.
