3 * gcc-interface/decl.c (gnat_to_gnu_entity): Robustify test for types
4 descendant of System.Address.
5 (gnat_to_gnu_subprog_type): Likewise.
7 2017-12-08 Jakub Jelinek <jakub@redhat.com>
9 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
10 exclusions to the comment.
12 2017-12-07 Martin Sebor <msebor@redhat.com>

37 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
39 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
40 QNX. At startup, the first mutex created has a non-zero ceiling
41 priority whatever its actual policy. This makes some tests fail
42 (c940013 for example).
44 2017-12-05 Bob Duff <duff@adacore.com>
46 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
47 Expand_Cleanup_Actions for N_Extended_Return_Statement.
48 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
49 N_Extended_Return_Statement by transforming the statements into a
50 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
51 It's too hard for Expand_Cleanup_Actions to operate directly on the
52 N_Extended_Return_Statement, because it has a different structure than
53 the other node kinds that Expand_Cleanup_Actions.
54 * exp_util.adb (Requires_Cleanup_Actions): Add support for
55 N_Extended_Return_Statement. Change "when others => return False;" to
56 "when others => raise ...;" so it's clear what nodes this function
57 handles. Use named notation where appropriate.
58 * exp_util.ads: Mark incorrect comment with ???.
60 2017-12-05 Javier Miranda <miranda@adacore.com>

80 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
82 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
83 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
84 Ada.Calendar.Clock_Time).
86 2017-12-05 Ed Schonberg <schonberg@adacore.com>
88 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
89 subprogram is overloaded, scan the list of homonyms in the same
90 scope, to find the inherited operation that may be overridden
92 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
94 2017-12-05 Bob Duff <duff@adacore.com>
96 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
97 Init_Assignment is rewritten, we need to set Assignment_OK on the new
98 node. Otherwise, we will get spurious errors when initializing via
101 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>

113 2017-12-05 Nicolas Setton <setton@adacore.com>
115 * terminals.c (__gnat_setup_child_communication): As documented,
116 __gnat_setup_child_communication should not terminate - it is intended
117 to be used as the child process of a call to fork(). However, execvp
118 might actually return in some cases, for instance when attempting to
119 run a 32-bit binary on a 64-bit Linux distribution when the
120 compatibility packages are not installed. In these cases, exit the
121 program to conform to the documentation.
123 2017-12-05 Olivier Hainque <hainque@adacore.com>

215 (Is_Potential_Scenario): Stop the traversal of a task body when
216 reaching an accept or select statement, and debug switch d_a is in

286 2017-12-05 Doug Rupp <rupp@adacore.com>
288 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
290 2017-12-05 Javier Miranda <miranda@adacore.com>
292 * checks.adb (Generate_Range_Check): Force evaluation of the node in
293 more cases. This patch was written to improve the code generated by
294 the CCG compiler but it is enabled for all targets since double
295 evaluation is always a potential source of inefficiency.

309 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
310 assignment if it is part of an Iterated_Component_Association: the
311 analysis needs to take place once the loop structure is analyzed and
312 the loop parameter made visible, because references to it typically
313 appear in the corresponding expression. This is necessary if the
314 expression is an aggregate, because previous pre-analysis of the
315 expression does not handle nested aggregates properly.
317 2017-12-05 Bob Duff <duff@adacore.com>
319 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an
320 allocator that is the expansion of a build-in-place function call.

330 retrieved load address to Init_Module.
331 * s-tsmona__linux.adb (Get): Honor the new interface.

335 offsetted by the module load address.
336 * s-dwalin.adb (Set_Load_Address): Simply set C.Load_Slide.
337 Do not alter the module Low and High (relative) addresses.
338 (Is_Inside): Improve documentation regarding the kinds of addresses
339 at hand and correct the test.
340 (Symbolic_Traceback): Use separate variables with explicit names
341 for the address in traceback (run-time value) and the address to
342 lookup within the shared object (module-relative). Adjust the
343 computation of address passed to Symbolic_Address for symbolization.

347 * opt.ads (Expand_Nonbinary_Modular_Ops): New flag.
348 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
349 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
350 other back-ends can also benefit from the front-end expansion. Remove
351 test for Modify_Tree_For_C in all callers to better share code.
352 * gnat1drv.adb (Adjust_Global_Switches): Set
353 Expand_Nonbinary_Modular_Ops when generating C code.
355 2017-12-05 Ed Schonberg <schonberg@adacore.com>
357 * exp_ch5.adb (Expand_Formal_Container_Loop): Ensure that the loop
358 parameter becomes invisible after analyzing the loop, which has been
359 rewritten as a while-loop.

364 and update for 64bit ports.
366 2017-12-05 Bob Duff <duff@adacore.com>
368 * exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
369 instead of the full name.
370 * sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
371 in the case of an instance of a generic.
373 2017-12-05 Arnaud Charlet <charlet@adacore.com>
375 (Adjust_Global_Switches): Create an alias GNAT_Annotate to map to

848 2017-11-09 Pascal Obry <obry@adacore.com>
850 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
851 only for foreign threads. We initialize the thread handle only if not
852 yet initialized. This happens in Enter_Task for foreign threads only.
853 But for native threads (Ada tasking) we do want to keep the real
854 handle (from Create_Task) to be able to free the corresponding
855 resources in Finalize_TCB (CloseHandle).

868 dispatch table is statically built.
869 (Make_DT): Declare constant the Interface_Table object associated with
870 an statically built dispatch table. For this purpose the Offset_To_Top
871 value of each interface is computed using the dummy object.
872 * exp_ch3.adb (Build_Init_Procedure): Do not generate code initializing
873 the Offset_To_Top field of secondary dispatch tables when the dispatch
874 table is statically built.

886 2017-11-09 Jerome Lambourg <lambourg@adacore.com>
888 * init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
889 as such capability is not available on the OS.

891 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
892 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
893 in particular a workaround with locks priority ceiling where a higher
894 priority task is allowed to lock a lower ceiling priority lock. This
895 also fixes the scheduling of FIFO tasks when the priority of a task is
897 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
899 2017-11-09 Yannick Moy <moy@adacore.com>

903 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
905 * namet.adb (Copy_One_Character): Add assumption for static analysis,
906 as knowledge that Hex(2) is in the range 0..255 is too complex for
908 (Finalize): Add assumption for static analysis, as the fact that there
909 are symbols in the table depends on a global invariant at this point in
911 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
912 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
915 2017-11-09 Javier Miranda <miranda@adacore.com>
917 * libgnat/s-rident.ads (Static_Dispatch_Tables): New restriction name.

955 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
956 * freeze.adb (Check_Component_Storage_Order): Default initialize
957 Comp_Byte_Aligned rather than silencing messages with pragma
958 Warnings(Off), which does not work for CodePeer initialization
959 messages, and given that here the possible read of an unitialized value
960 depends on a proper use of parameters by the caller.
961 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
962 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
963 * sem_ch3.adb (Build_Derived_Array_Type): Default initialize

967 (Analyze_Case_Expression): Rescope checking block within branch where
968 Others_Present is set by the call to Check_Choices.
969 * sem_ch5.adb (Analyze_Assignment): Default initialize
971 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
972 and restructure code to defend against previous errors, so that, in
973 that case, control does not flow to the elsif condition which read an
974 uninitialized Obj_Decl.
975 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
976 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
977 which seem to be left uninitialized and possibly read in some cases.
978 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
979 precisely. This requires to exchange the test for exiting in case of
980 too many positions and the increment to Position, inside the loop.
981 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
982 which cannot be read uninitialized, but the reasons for that are quite
984 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
985 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
987 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
988 and test for presence of non-null Opnd_Type before testing its scope,
989 in a test which would read its value uninitialized, and is very rarely
990 exercized (it depends on the presence of an extension of System).
991 * sem_spark.ads: Update comment to fix name of main analysis procedure.
992 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
994 * set_targ.adb (FailN): Mark procedure with No_Return.

1000 2017-11-09 Eric Botcazou <ebotcazou@adacore.com>
1002 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

1007 * sem_prag.adb (Analyze_Part_Of): Reword error message.
1008 (Get_SPARK_Mode_Type): Do not raise Program_Error in case pragma
1009 SPARK_Mode appears with an illegal mode, treat this as a non-existent

1014 * sem_ch4.adb (Analyze_Call): Reject a call to a function that returns

1022 when processing generic instances.
1024 2017-11-09 Bob Duff <duff@adacore.com>
1026 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1027 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1028 objects can have those special values. Valid_Name_Id could usefully be
1029 used all over the compiler front end, but that's too much trouble for
1030 now. If we did that, we might want to rename:
1031 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1032 For parameters of type Valid_Name_Id, remove some redundant tests,
1033 including the ones found by CodePeer. Use Is_Valid_Name instead of
1034 membership test when appropriate.
1035 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1036 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1037 "in Error_Name_Or_No_Name".
1038 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in

2461 2017-10-09 Bob Duff <duff@adacore.com>
2463 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2464 code so if BIPAlloc is not passed in, it will likely raise
2465 Program_Error instead of cause miscellaneous chaos.

2467 as for the other Is_B-I-P... functions.
2468 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2469 aggregate whose ancestor part is a build-in-place call returning a

2473 creating an Itype for a library unit entity.
2474 (Check_Initialization): Avoid spurious error message on
2475 internally-generated call.
2476 * sem_ch5.adb (Analyze_Assignment): Handle the case where the

2480 implies >= Ada 2005.

2520 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2521 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2522 limited. This is for the case of a function call that occurs as the
2523 default for a record component.
2524 (Expand_N_Object_Declaration): Deal with the case where expansion has
2525 created an object declaration initialized with something like

2531 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2532 the attribute is an object, but it may appear within a conversion. The
2533 object itself must be retrieved when generating the range test that
2534 implements the validity check on a scalar type.

2560 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous

2595 (Is_Build_In_Place_Result_Type): New function to accompany
2596 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2597 sometimes we just have the type on our hands, not the function. For
2598 now, does the same thing as the old version, so build-in-place is
2599 disabled for nonlimited types, except that you can use -gnatd.9 to
2601 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2602 accompany Is_Build_In_Place_Function and

2607 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the

2610 determine whether "return (...agg...);" is returning from a
2611 build-in-place function.

2613 Remove assumption that b-i-p implies limited (initialization of
2614 In_Place_Expansion).
2615 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2616 an unchecked conversion. Add assertions.
2617 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2618 secondary stack here, just because the type needs finalization. That

2640 b-i-p implies >= Ada 2005.
2641 * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
2642 (Expr), in case Pool_Id is not set.
2643 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2644 qualified or converted.
2645 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2646 (Param)) = N_Identifier; that's all it could be.
2647 * sinfo.ads: Comment fixes.
2648 * snames.ads-tmpl: Comment fixes.

2681 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
2682 for types in expression if the function is within a generic unit.
2683 * sem_res.adb (Resolve): In a generic context do not freeze an
2684 expression, unless it is an entity. This exception is solely for the
2685 purpose of detecting illegal uses of deferred constants in generic

2760 redundant clauses. A new parameter has also been added to force

3631 2017-09-08 Yannick Moy <moy@adacore.com>
3633 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3634 return the entity associated with the call.
3635 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3636 Replace the internal Get_Function_Id with the new
3637 Sem_Aux.Get_Called_Entity.
3638 (Iterate_Call_Parameters): New
3639 procedure to iterate on formals and actuals at the same time.
3640 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3641 Set SPARK_Mode from spec when set, for analysis
3642 of instance. Restore after analysis of instance.
3643 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3644 set, for analysis of body instance. Restored automatically at
3645 the end of the subprogram.
3646 * gnat1drv.adb (Adjust_Global_Switches): Set
3647 Check_Validity_Of_Parameters to False in GNATprove mode.
3648 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3651 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3653 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3654 (New_Copy_Tree): ...there. Reset the hash tables only if they
3655 were used in the previous invocation.
3656 * s-htable.adb: Fix typo.
3658 2017-09-08 Bob Duff <duff@adacore.com>
3660 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3662 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3664 * sem_aggr.adb: minor style fix.
3666 2017-09-08 Bob Duff <duff@adacore.com>
3668 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3669 no current source file.
3670 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3671 Print something helpful in case N is invalid.
3672 * sprint.ads: Minor comment fix.
3674 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3676 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3679 2017-09-08 Bob Duff <duff@adacore.com>
3681 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3682 Ada_2020, along the same lines as the other Ada version pragmas.
3684 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3686 * sem_ch12.adb: Minor typo fixes and reformatting.
3688 2017-09-08 Yannick Moy <moy@adacore.com>
3690 * sem_aggr.adb (Resolve_Record_Aggregate):
3691 Rewrite bounds of aggregate subexpressions which may depend on
3692 discriminants of the enclosing aggregate.
3694 2017-09-08 Yannick Moy <moy@adacore.com>
3696 * sem_ch5.adb: Prevent assertion failure on illegal code.
3698 2017-09-08 Yannick Moy <moy@adacore.com>
3700 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3701 calling Renamed_Entity on an entity which cannot be a renaming.
3703 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3705 * exp_aggr.adb: Add with & use clause for Urealp.
3706 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3707 elementary types instead of just discrete types.
3708 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3709 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3710 Be prepared for the FP zero value in the memset case. Add small
3713 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3715 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3718 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3720 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3721 of New_Copy because the latter leaves the syntactic structure of
3722 the tree inconsistent (a child is accessible through two parents)
3723 and prevents proper replication of itypes by subsequent calls
3725 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3726 New_Copy because the latter leaves the syntactic structure of the
3727 tree inconsistent (a child is accessible through two parents)
3728 and prevents proper replication of itypes by subsequent calls
3730 * sem_util.adb (In_Subtree): New routine.

3735 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3737 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3738 for aspect Default_Value is a static scalar value, but it does
3739 not freeze the type. Yhis allows for subsequent representation
3740 clauses for the type.
3742 2017-09-08 Javier Miranda <miranda@adacore.com>
3744 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3745 not add entries into the undefined reference table when we are
3746 compiling with errors ignored.
3748 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3750 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3751 check if the instance is within an enclosing instance body. The
3752 formal package was legal in the enclosing generic, and is
3753 legal in the enclosing instantiation. This optimisation may be
3754 applicable elsewhere, and it also removes spurious errors that
3755 may arise with on-the-fly processing of instantiations that
3756 contain Inline_Always subprograms.
3758 2017-09-08 Vincent Celier <celier@adacore.com>
3760 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3762 2017-09-08 Justin Squirek <squirek@adacore.com>
3764 * checks.adb (Insert_Valid_Check): Manually decorate
3765 the generated temporary for range valdity checks.
3767 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3769 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3771 2017-09-08 Justin Squirek <squirek@adacore.com>
3773 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3774 case to handle underscore flags.
3775 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3776 new procedure to handle underscores.
3778 2017-09-08 Javier Miranda <miranda@adacore.com>
3780 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3781 divisions with fixed point results to avoid generating twice
3782 the runtime check on divide by zero.
3783 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3784 not evaluated twice (once for their runtime checks and once for
3785 their regular computation).
3787 2017-09-08 Yannick Moy <moy@adacore.com>
3789 * sem_prag.adb (Analyze_Part_Of): Add missing
3790 return statements after issuing errors. Add detection of
3791 out-of-order item and single concurrent type.

3906 literals, so that Pure_Barriers is no longer in range of the
3907 Cunit_Boolean_Restrictions subtype.
3909 2017-09-08 Nicolas Roche <roche@adacore.com>
3911 * a-taster.ads, a-taster.adb: Move to libgnarl
3912 * gcc-interface/Makefile.in: Remove obsolete targets. Code cleanups.
3913 Add support for files in libgnarl.
3915 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3917 * exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
3918 accessibility check to an interface conversion, whose purpose
3919 is to perform a pointer adjustment in a dispatching call.
3920 * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
3921 when the actual is a construct that involves a dereference of an
3922 expression that includes a formal of the enclosing subprogram,
3923 In such cases, the accessibility level of the actual is that of
3924 the corresponding formal, which is passed in as an additional
3925 actual in the outer call.
3927 2017-09-08 Bob Duff <duff@adacore.com>
3929 * exp_intr.adb (Add_Source_Info): Do not decode
3930 file names; they were not encoded in the first place.
3932 2017-09-08 Bob Duff <duff@adacore.com>
3934 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
3935 exceptions instead of crashes. Check for absurdly long strings
3936 and empty strings. Empty strings cause trouble because they can
3937 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3938 be empty, which causes an array index out of bounds.
3939 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
3942 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3944 * sem_util.adb (Is_CCT_Instance): allow use in
3945 the context of protected types.
3947 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3964 not skip a loop coming from source which is rewritten into a loop.
3966 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3968 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
3969 wrapper has convention Ada, to prevent spurious warnings on
3970 unconstrained array parameters.

3993 changes for Include_Subprogram_In_Messages.
3994 * sem_ch5.adb (Check_Unreachable_Code): Supply Node parameter when
3995 generating warning message.
3997 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3999 * par-ch4.adb (P_Iterated_Component_Association): Place construct
4000 under -gnat2020 flag, given that it is a future feature of
4002 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
4003 defining identifier as referenced to prevent spurious warnings:
4004 corresponding loop is expanded into one or more loops whose
4005 variable has the same name, and the expression uses those names
4006 and not the original one.
4008 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4010 * sem_elab.adb (Check_A_Call): Do not consider
4011 references to internal variables for SPARK semantics.

4028 always copy the representation aspects onto the subtype.
4030 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
4032 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
4033 Correction of the return type from access type to option type.
4034 (Simple_HTable): Moving the Instance_Data to ads file.

4058 2017-09-08 Javier Miranda <miranda@adacore.com>
4060 * exp_ch6.adb (Unqual_BIP_Function_Call): Adding
4061 missing checks on the presence of Entity() before checking the
4064 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4066 * sem_ch6.adb (Analyze_Expression_Function): Reorder some
4067 statements, use local variable and remove unnecessary processing.

4077 * exp_ch6.adb (Replace_Renaming_Declaration_Id): New
4078 subprogram containing code that was previously inside
4079 Make_Build_In_Place_Call_In_Object_Declaration since it is also

4115 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
4116 access to interface types. Remove also the accessibility check.
4118 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4120 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4121 all the types that are referenced by the expression.
4122 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4123 a completion instead of manually freezing the type of the
4125 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4127 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4129 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4130 New procedure, auxiliary to Expand_Pragma_Check, to handle
4131 references to the discriminants of a protected type within a
4132 precondition of a protected operation. This is needed because
4133 the original precondition has been analyzed in the context of
4134 the protected declaration, but in the body of the operation
4135 references to the discriminants have been replaved by references
4136 to the discriminants of the target object, and these references
4137 are only created when expanding the protected body.
4139 2017-09-08 Yannick Moy <moy@adacore.com>
4141 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4144 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4146 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4147 unchecked union, do not emit checks for its (non-existent)
4148 discriminants, or for variant parts that depend on them.
4150 2017-09-08 Justin Squirek <squirek@adacore.com>
4152 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4153 Find_Comparison_Type.Try_One_Interp): Add check for generic
4156 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4158 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4159 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4160 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4161 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4162 remaining references to AAMP_On_Target.
4164 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4166 * style.adb: Fix typo.
4168 2017-09-08 Javier Miranda <miranda@adacore.com>
4170 * einfo.adb (Underlying_Type): Add missing support for class-wide
4171 types that come from the limited view.
4172 * exp_attr.adb (Attribute_Address): Check class-wide type
4173 interfaces using the underlying type to handle limited-withed
4175 (Attribute_Tag): Check class-wide type interfaces using
4176 the underlying type to handle limited-withed types.
4178 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4180 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4181 over a subtype of a type with a static predicate, taking into
4182 account the predicate function of the parent type and the bounds
4183 given in the loop specification.
4184 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4185 a loop specification that is a subtype indication whose type mark
4186 is a type with a static predicate, inherit predicate function,
4187 used to build case statement for rewritten loop.
4189 2017-09-08 Justin Squirek <squirek@adacore.com>
4191 * lib-load.adb: Modify printing of error message to exclude file
4194 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4196 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4197 don't inline subprograms declared in both visible and private
4199 (In_Package_Spec): previously In_Package_Visible_Spec; now
4200 detects subprograms declared both in visible and private parts
4203 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4205 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4206 the type is an anonymous array in an object declaration, whose
4207 component type has an invariant, use the object declaration
4208 as the insertion point for the invariant procedure, given that
4209 there is no explicit type declaration for an anonymous array type.
4211 2017-09-08 Bob Duff <duff@adacore.com>
4213 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
4215 2017-09-08 Bob Duff <duff@adacore.com>
4217 * a-strfix.adb (Trim): Compute Low and High only if needed.
4219 2017-09-08 Justin Squirek <squirek@adacore.com>

4222 source file is missing.
4224 2017-09-08 Bob Duff <duff@adacore.com>
4227 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4228 Default_WCEM by default (i.e. if the encoding is not specified
4229 by the Form string).
4231 2017-09-08 Bob Duff <duff@adacore.com>
4233 * s-trasym.ads (Hexa_Traceback): If
4234 Suppress_Hex is True, print "..." instead of a hexadecimal
4236 * s-trasym.adb: Ignore No_Hex in this version.
4239 2017-09-08 Bob Duff <duff@adacore.com>
4241 * debug.adb: Minor reformatting.
4243 2017-09-08 Bob Duff <duff@adacore.com>
4245 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4246 code so it doesn't trigger an "uninit var" warning.
4248 2017-09-08 Nicolas Roche <roche@adacore.com>
4250 * s-hibaen.ads: Remove obsolete file.
4252 2017-09-08 Arnaud Charlet <charlet@adacore.com>

4269 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4271 * debug.adb (dA): Adjust comment.
4272 * gnat1drv.adb (Gnat1drv): Likewise.
4273 * opt.ads (List_Representation_Info_Extended): New variable.
4274 * repinfo.adb (List_Record_Info): Split implementation into...
4275 (Compute_Max_Length): ...this. Recurse on records if requested.
4276 (List_Record_Layout): Likewise.
4277 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4278 statement, accept '0' and set List_Representation_Info_Extended
4280 * usage.adb (Usage): Document new -gnatRe variant.
4282 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4284 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4285 Do not save the given entity in the global variable Default_Pool
4286 if the pragma appears within a generic unit.
4288 2017-09-08 Bob Duff <duff@adacore.com>
4290 * errout.adb (Delete_Warning): Do not
4291 decrement Warnings_Treated_As_Errors. This is called before
4292 Warnings_Treated_As_Errors has been incremented to account for
4293 this warning. Decrementing it here can lead to negative values
4294 of Warnings_Treated_As_Errors, raising Constraint_Error in
4295 checks-on builds, and causing the compiler to return an error
4296 code in checks-off builds.
4298 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4300 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4301 entities of named concurrent types as Ref_Id and not of anonymous
4302 concurrent objects (because callers already know when a conversion
4303 is necessary and can easily do it); also, do not expect protected
4304 types or protected objects as Context_Id (because no flow-related
4305 SPARK pragmas are attached there); reflect these changes in a
4306 more precise comment.
4308 2017-09-08 Olivier Hainque <hainque@adacore.com>
4310 * g-altive.ads: Add documentation.
4312 2017-09-08 Bob Duff <duff@adacore.com>
4314 * sem_util.ads, debug.adb: Minor comment fix.
4315 * erroutc.ads: Comment fix.
4317 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4319 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4320 for compatibility of component types of formal and actual in an
4321 instantiation of a child unit, when the component type of the
4322 formal is itself a formal of an enclosing generic.
4324 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4326 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4327 sem_prag.adb to make it available for GNATprove; for concurrent
4328 types replace custom scope climbing with Scope_Same_Or_Within; for
4329 single concurrent objects add scope climbing (with Scope_Within),
4330 which was not there (that's the primary semantic change of this
4331 commit); also, when comparing a single concurrent object with
4332 its corresponding concurrent type rely on equality of types,
4333 not of objects (because that's simpler to code).
4334 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4335 (Analyze_Global_Item): adjust special-casing of references to the
4336 current instance of a concurrent unit in the Global contracts
4337 of task types and single tasks objects; similar for references
4338 in the protected operations and entries of protected types and
4339 single protected objects (in all these cases the current instance
4340 behaves as an implicit parameter and must not be mentioned in
4341 the Global contract).
4343 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4345 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4346 function calls returning a record within a subprogram call,
4349 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4351 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4352 name that designates the current instance of a child unit in its
4353 own body and appears as the prefix of a reference to an entity
4354 local to the child unit.
4355 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4358 2017-09-08 Yannick Moy <moy@adacore.com>
4360 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that

4365 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4366 warnings on internal units in configurable run time mode.
4368 2017-09-08 Bob Duff <duff@adacore.com>
4370 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4371 representation items from interfaces that the derived type
4372 implements, not just from the parent type.
4373 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4374 this to return an empty list when there are no interfaces.
4375 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4376 * sem_attr.adb: Minor comment fix.
4378 2017-09-08 Doug Rupp <rupp@adacore.com>
4380 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
4383 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4385 * exp_ch4.adb (Expand_N_Allocator): Generate a
4386 call to Allocate_Any_Controlled when the allocation does not
4387 require any initialization.
4389 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4391 * sem_util.adb (Copy_Node_With_Replacement):
4392 Update the Renamed_Object field of a replicated object renaming
4395 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4397 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4398 conversions and components of objects. Simplified the detection
4399 of the Count attribute by identifying the corresponding run-time
4402 2017-09-08 Yannick Moy <moy@adacore.com>
4404 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4405 sem_type.adb, sinfo.ads: Minor reformatting.
4407 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4409 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4410 of Freeze_Profile, used to inhibit the freezing of the profile
4411 of an expression function declared within a nested package, when
4412 some type in the profile depends on a private type declared in
4413 an enclosing package.
4415 2017-09-08 Bob Duff <duff@adacore.com>
4417 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4418 the subunit case. It's still OK to set it in the "missing subunits"
4419 case, because that won't cause the obsolete .ali files that cause
4422 2017-09-08 Bob Duff <duff@adacore.com>

4464 the placement of a primitive operation O that renames an operation
4465 R declared in an inner package, and which is thus not a primitive

4903 debugging printouts comparing the two orders." Now it means
4904 "do not run Elab_New." This is of use if there are bugs that

4949 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4951 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4952 entity of a mutable type and the right-hand side is a conditional
4953 expression, resolve the alternatives of the conditional using
4954 the base type of the target entity, because the alternatives
4955 may have distinct subtypes. This is particularly relevant if
4956 the alternatives are aggregates.
4958 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4960 * checks.adb (Apply_Predicate_Check): If the expression is an
4961 aggregate that is the RHS of an assignment, apply the check to
4962 the LHS after the assignment, rather than to the aggregate. This
4963 is more efficient than creating a temporary for the aggregate,
4964 and prevents back-end crashes when the aggregate includes a
4965 dynamic "others' association.
4967 2017-09-06 Yannick Moy <moy@adacore.com>
4969 * sem_ch12.adb (Analyze_Instance_And_Renamings):
4970 Set variable to ignore SPARK_Mode in instance before the analysis
4971 of the generated package declaration.
4973 2017-09-06 Yannick Moy <moy@adacore.com>
4975 * sem_res.adb (Resolve_Call): Do not issue a
4976 message for calls inside expression function, unless body was
4977 seen and is candidate for inlining.
4979 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4981 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
4982 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
4983 body. do not freeze the formals of the generic unit.
4985 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4987 * errout.adb (Error_Msg): Separate the
4988 treatment for warning vs. style messages in inlinings and
4989 instantiations. Prevents blowups on calls to Warn_Insertion for
4990 style messages, which should not be called in that case because
4991 Warning_Msg_Char is not set.
4993 2017-09-06 Justin Squirek <squirek@adacore.com>
4995 * sem_prag.adb (Check_VFA_Conflicts): Created
4996 to group all Volatile_Full_Access checks relating to other
4997 representation pragmas (Mark_Component_Or_Object): Created
4998 to centeralize the flagging of attributes for the record type
4999 component case, a pragma applied individually to a component, and
5001 (Process_Atomic_Independent_Shared_Volatile):
5002 Add propagation of certain pragmas to record components and move
5003 evaluation of VFA checks
5005 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5007 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
5008 Do not warn on conditions that are not obeyed for Inline_Always
5009 subprograms, when assertions are not enabled.
5011 2017-09-06 Arnaud Charlet <charlet@adacore.com>
5013 * sem_util.adb (Unique_Entity): For abstract states return their
5016 2017-09-06 Bob Duff <duff@adacore.com>
5018 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5019 that is a proper body corresponding to a stub, we defer the
5020 adjustment of the sloc until after the correct adjustment has
5021 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5022 the adjustment, because it will be outside the range in (the old,
5023 incorrect) S_Adjustment.
5024 * inline.adb: Use named notation for readability and uniformity.
5025 * sinput-l.adb: Minor improvements to debugging output printed
5027 * sinput-l.ads (Create_Instantiation_Source): Minor comment
5030 2017-09-06 Vincent Celier <celier@adacore.com>
5032 * make.adb: Do not invoke gprbuild for -bargs -P.
5034 2017-09-06 Sylvain Dailler <dailler@adacore.com>
5036 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
5037 case when Op is of kind N_Qualified_Expression. In this case,
5038 the function is called recursively on the subexpression like in
5040 * make.adb: Minor reformatting
5042 2017-09-06 Justin Squirek <squirek@adacore.com>
5044 * einfo.adb (Set_Linker_Section_Pragma): Modify
5045 Set_Linker_Section_Pragma to be consistant with the "getter"
5046 Linker_Section_Pragma.
5047 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5048 checking for container loops so that the index cursor is not
5049 directly changable by the user with the use of E_Loop_Parameter.
5050 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
5051 * sem_warn.adb (Check_References): Revert previous change.
5053 2017-09-06 Bob Duff <duff@adacore.com>

5060 * sem_prag.adb (Analyze_Depends_Global): Reinforce test on object
5061 declarations to only consider valid uses of Global/Depends those on
5062 single concurrent objects.

5084 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
5085 gnatname.adb: Remove the Project Manager from the GNAT tools.
5086 * gcc-interface/Makefile.in: ditto.
5088 2017-09-06 Bob Duff <duff@adacore.com>
5090 * sem_util.ads: Minor comment fix.
5092 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5094 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5095 Generate a freeze node for the actual of a formal package, if
5096 the actual is declared in the same unit and has a corresponding
5097 body, to prevent the current instance from being frozen before
5100 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5102 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.
5104 2017-09-06 Yannick Moy <moy@adacore.com>

5122 missing case of controlled generalized indexing.
5123 (Is_Source_Object): Use routine Strip to remove indirections.
5124 (Strip): New routine.
5126 2017-09-06 Bob Duff <duff@adacore.com>
5128 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5129 we include the proper header. Otherwise, we just declare the necessary
5130 things from the capabilities library. This is so we can build on
5131 machines without that library, while still enabling that library.
5132 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5133 simply return 0 if the library is not present, or not included
5136 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5138 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

5149 has no parameter specification and no entry index, use the entry name
5150 as the end of the generated SCO statement.
5152 2017-09-06 Steve Baird <baird@adacore.com>
5154 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5155 uses of 'Image and related attributes as having side effects in
5156 order to avoid replicating such uses.
5157 * pprint.ads (Expression_Image) Add new generic formal flag
5158 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5159 (eventually) override the default.
5160 * pprint.adb (Expression_Image) If the new flag is set, then
5161 suppress the ".all" suffix when displaying a dereference whose
5162 prefix is a use of a value-capturing compiler temp of the sort
5163 generated by Expr_Util.Remove_Side_Effects .
5164 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

5178 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
5179 so that applies to any entity.
5181 2017-09-06 Yannick Moy <moy@adacore.com>
5183 * sem_ch3.adb (Derived_Type_Declaration): Use
5184 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5186 2017-09-06 Javier Miranda <miranda@adacore.com>
5188 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5191 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5193 * sem_dim.adb (Analyze_Dimension): In an instance, a type

5196 (Dimensions_Of_Operand): Ditto.
5198 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5200 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
5201 null procedures when GNAT coverage is used, so that their (empty)
5202 bodies are properly covered.

5212 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
5213 Universal_Real and the context is a floating-point type, resolve

5221 2017-09-06 Yannick Moy <moy@adacore.com>
5223 * freeze.adb (Check_Inherited_Conditions): Rewriting
5224 of inherited preconditions and postconditions should only occur
5225 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5226 be confused with SPARK_Mode being On.
5228 2017-09-06 Yannick Moy <moy@adacore.com>

5242 * sem_ch7.adb: Add with clause for GNAT.HTable.
5243 (Entity_Table_Size): New constant.
5244 (Entity_Hash): New function.
5245 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5246 (Is_Subprogram_Ref): Rename into...
5247 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5248 the table instead of bailing out on them. Scan the value of constants
5249 if it is not known at compile time.
5250 (Contains_Subprograms_Refs): Rename into...
5251 (Scan_Subprogram_Refs): ...this.
5252 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5253 Is_Public flag on subprograms if they are not actually referenced.
5254 (Hide_Public_Entities): Beef up comment on the algorithm.
5255 Reset the table of subprograms on entry.
5257 2017-09-06 Yannick Moy <moy@adacore.com>

5311 2017-09-06 Bob Duff <duff@adacore.com>
5313 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint

5342 * sem_type.adb (Interface_Present_In_Ancestor): Within an
5343 expression function, or within a spec expression (default value,

5364 Move Ada.Command_Line.Response_File to System.Response_File,
5365 and make Ada.Command_Line.Response_File into a rename of
5366 System.Response_File. This is to avoid having gnatbind depend
5367 Ada.Command_Line, which would damage the bootstrap process now
5368 that Ada.Command_Line contains modern Ada (the raise expression).
5369 * gnatbind.adb: Avoid dependence on
5370 Ada.Command_Line. Depend on System.Response_File instead
5371 of Ada.Command_Line.Response_File. Change one call to
5372 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5373 to Ada.Command_Line.Argument_Count to use Arg_Count.
5374 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5376 2017-09-06 Bob Duff <duff@adacore.com>

5384 "Assert(False)" with "return Iter", because if an iterable

5386 overriding or inherited default iterator.
5388 2017-09-06 Yannick Moy <moy@adacore.com>
5390 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

5399 (Write_Field15_Name): Update the output for
5400 Status_Flag_Or_Transient_Decl.
5401 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
5402 to loop parameters. Update the documentation of the attribute
5403 and the E_Loop_Parameter entity.
5404 * exp_ch7.adb (Process_Declarations): Remove the bogus guard
5405 which assumes that cursors can never be controlled.
5406 * exp_util.adb (Requires_Cleanup_Actions): Remove the bogus
5407 guard which assumes that cursors can never be controlled.

5422 * sem_attr.adb: Comment correction.
5424 2017-09-06 Gary Dismukes <dismukes@adacore.com>

5513 not retrievable as selected components.
5515 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5517 * sem_util.adb (Needs_One_Formal): The first formal of such a

5557 not visible in the object.
5558 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5559 side may be derived from that of the left-hand side (as in the
5560 case of an assignment with a change of representation) so the
5561 discriminant to be used in the retrieval of the value of the
5562 component must be the entity in the type of the right-hand side.

6137 * exp_ch6.adb (Expand_Call_Helper): When locating the
6138 accessibility entity created for an access parameter, handle
6139 properly a reference to a formal of an enclosing subprogram. if
6140 the reference appears in an inherited class-wide condition, it
6141 is the rewriting of the reference in the ancestor expression,
6142 but the accessibility entity must be that of the current formal.
6144 2017-05-02 Javier Miranda <miranda@adacore.com>
6146 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6181 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6182 procedure body for a local (sub)type declaration within a
6183 predicate function. Invariant checks do not apply to these, and
6184 the expansion of the procedure will happen in the wrong scope,
6185 leading to misplaced freeze nodes.
6187 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6189 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6190 to analyze generated actions. If the main unit is a body,

6195 * einfo.adb (Declaration_Node): flip branches of
6196 an IF statement to avoid repeated negations in its condition;

6226 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6227 Refine predicate for the case where the primitive operation
6228 is a renaming of equality. An overriding operation that is
6229 a user-defined renaming of predefined equality inherits its
6230 slot from the overridden operation. Otherwise it is treated
6231 as a predefined op and occupies the same predefined slot as
6232 equality. A call to it is transformed into a call to its alias,
6233 which is the predefined equality. A dispatching call thus uses
6234 the proper slot if operation is further inherited and called
6235 with class-wide arguments.
6237 2017-05-02 Justin Squirek <squirek@adacore.com>
6239 * errout.adb (Set_Msg_Text): Add a case to switch the message

6241 about a run-time exception.
6242 * opt.ads Add a new Warning_Mode value for new switch
6243 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6244 to handle new warning mode

6248 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6250 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6251 declaration that operates on some fixed point type.

6270 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6272 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6273 statement if the initialization call is a null procedure, as
6274 can happen with a controlled type with no explicit Initialize
6275 procedure, or an array of such.
6276 * exp_ch7.adb (Process_Object_Declaration): For a type with
6277 controlled components that has a trivial Initialize procedure,
6278 insert declaration for finalization counter after object

6281 finalization block and attendant declarations if component has
6282 a trivial Initialize procedure.
6283 (Make_Init_Call): Do not generate a call if controlled type has
6284 a trivial Initialize procedure.

6314 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6316 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6317 parameter Array_Comp to indicate the case of an array object
6318 with null-excluding components.
6319 * checks.adb (Null_Exclusion_Static_Checks):
6320 Call Compile_Time_Constraint_Error instead of
6321 Apply_Compile_Time_Constraint_Error in the component case. Also
6322 call that when Array_Comp is True, with an appropriate warning for
6323 the array component case. Only create an explicit initialization
6324 by null in the case of an object of a null-excluding access type
6325 (and no longer do that in the component case).
6326 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6327 Array_Comp defaulted to False. Pass Empty for the Comp
6328 actual when calling Null_Exclusion_Static_Checks in the case
6329 where Comp_Decl matches Object_Decl, because we don't have a
6330 component in that case. In the case of an object or component
6331 of an array type, pass True for Array_Comp on the recursive call

6336 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6337 compute the linux priority from the Ada priority. Call this everywhere
6338 required. In particular, the previous version was not doing this
6339 computation when setting the ceiling priority in various places. It
6340 was just converting to C.int, which results in a ceiling that is off
6343 2017-05-02 Ed Schonberg <schonberg@adacore.com>

6362 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6363 here from exp_ch9, to recognize objects whose creation requires
6364 dynamic allocation, so that the proper warning can be emitted
6365 when restriction No_Implicit_Heap_Allocation is in effect.
6366 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6367 to emit proper warning when an object that requires dynamic

6432 operator /= into negation of operator = when needed.
6433 (Expand_SPARK): Call new
6434 function to expand operator /=.
6436 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6438 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6439 Simplify the expression for a fixed-fixed division to remove
6440 divisions by constants whenever possible, as an optimization
6441 for restricted targets.

6445 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6447 2017-05-02 Bob Duff <duff@adacore.com>
6449 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6450 to find primitive ops, instead of using an Identifier that will
6451 later be looked up. This is necessary because these ops are not
6452 necessarily visible at all places where we need to call them.
6453 * exp_util.ads: Minor comment fix.
6455 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6457 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6458 references are fully conformant if they are both expansions
6459 of the discriminant of a protected type, within one of the
6460 protected operations. One occurrence may be expanded into a
6461 constant declaration while the other is an input parameter to
6462 the corresponding generated subprogram.

6466 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6467 recursivly searching composite-types for null-excluding access
6468 types and verifying them.
6469 (Analyze_Object_Declaration): Add a
6470 call to Check_Null_Excluding_Components for static verification
6471 of non-initialized objects.
6472 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6473 a parameter for a composite-type's component and an extra case
6474 for printing component information.
6476 2017-05-02 Yannick Moy <moy@adacore.com>
6478 * sem_ch10.adb (Analyze_Subunit): Take

6492 array components specially.
6494 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6496 * sem_ch8.adb (Premature_Usage): If the premature usage of
6497 an entity is as the expression in its own object decaration,
6498 rewrite the reference as Any_Id to prevent cascaded errors or
6499 compiler loops when such an entity is used in an address clause.
6501 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6503 * gcc-interface/decl.c (components_to_record): Add missing guard.

6508 Put back pending fields onto the regular list if the misalignment
6509 happens to cancel itself.
6511 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6513 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6514 controlling actual in a prefixed call, preserve the original node
6515 information if the prefix itself has been rewritten, for ASIS use.
6517 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6519 * exp_ch6.adb (Insert_Post_Call_Actions):
6520 Code clean up. Insert the post-call actions after an enclosing
6521 procedure call when N denotes a function call and appears as an
6522 actual parameter in the procedure call.
6524 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6526 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6527 for the component, also reject the attribute if the component
6528 doesn't end on a byte boundary and its scalar storage order is
6529 different from that of the enclosing record type.
6531 2017-04-28 Javier Miranda <miranda@adacore.com>
6533 * atree.ads (Info_Messages): Removed.

6563 2017-04-28 Bob Duff <duff@adacore.com>
6565 * sem_util.ads, sem_util.adb (Might_Raise): New function
6566 that replaces Is_Exception_Safe, but has the opposite
6567 sense. Is_Exception_Safe was missing various cases -- calls inside
6568 a pragma Debug, calls inside an 'if' or assignment statement,
6569 etc. Might_Raise now walks the entire subtree looking for things
6571 * exp_ch9.adb (Is_Exception_Safe): Remove.
6572 (Build_Protected_Subprogram_Body): Replace call to
6573 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6574 constants where possible).
6575 * exp_ch7.adb: Rename Is_Protected_Body -->
6576 Is_Protected_Subp_Body. A protected_body is something different

6605 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6606 Interrupt_Handler and Attach_Handler): Generate reference
6607 to protected operation to prevent spurious warnings about
6608 unreferenced entities. Previous scheme failed with style checks
6611 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6613 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6614 that follows an expression function must not be relocated to
6615 the generated body, because it applies to the code that follows.
6617 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6619 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6620 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6621 code that might violate the more stringent checking for 'Access
6622 introduced in Ada 2005.
6624 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6626 * a-cforse.adb: minor style fix in comment.
6628 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6630 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6631 initialize Block_Decls variable.
6632 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6633 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

6642 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6644 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6646 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6647 node between access types, freeze the designated type as well,
6648 so that dispatch table pointers are created in the proper scope,
6649 and not in the constructed body of the expression function.
6651 2017-04-28 Bob Duff <duff@adacore.com>
6653 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6654 value makes large compilations faster, but small compilations slower.
6656 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6658 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6660 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6662 * erroutc.adb (Compilation_Errors): Do not consider info messages
6663 as suitable warnings when warnings must be treated as errors.
6664 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6665 internally-generated packages when outputting completion
6667 * errout.adb (Output_Messages): Do not consider info messages as

6670 suitable warnings when warnings must be treated as errors.
6672 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6674 * warnsw.ads: Minor fix for incorrect wording in comment.
6676 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6678 * sem_res.adb (In_Instance_Code): New predicate in
6679 Valid_Conversion, to determine whether a type conversion appears
6680 as (or within) an actual for a formal object. Type conversions
6681 in instances are not rechecked in Valid_Conversion because
6682 visibility changes between generic location andi instance may
6683 lead to spurious errors, but conversions within an actual must be
6684 fully checked, and they are not fully resolved when pre-analyzing
6687 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6689 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6690 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6691 of the relocated node will have mangled Parent pointers.
6692 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6693 tables used in conjunction with entity and itype replication.
6694 (Visit_Entity): Rewrite the restriction on which entities

6729 (Restore_Warnings): Likewise.
6730 (Save_Warnings): Likewise.
6731 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6732 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6733 components_to_record.
6734 (gnu_field_to_gnat): New function.
6735 (warn_on_field_placement): Likewise.
6736 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6737 parameters. Rename local variables and adjust recursive call.
6738 Rework final scan of the field list and implement warnings on the
6739 problematic placement of specific sorts of fields.
6741 2017-04-27 Bob Duff <duff@adacore.com>
6743 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6748 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6749 For efficiency, cache results of Is_Internal_File_Name and
6750 Is_Predefined_File_Name in the Units table. This avoids a lot
6751 of repeated text processing.
6753 2017-04-27 Emmanuel Briot <briot@adacore.com>
6755 * g-comlin.adb (Sort_Sections): remove useless test.
6757 2017-04-27 Claire Dross <dross@adacore.com>
6759 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6760 allow the use of regular equality over elements in contracts.
6761 (Formal_Model): Ghost package containing model functions that are
6762 used in subprogram contracts.
6763 (Current_To_Last): Removed, model functions should be used instead.
6764 (First_To_Previous): Removed, model functions should be used instead.
6765 (Strict_Equal): Removed, model functions should be used instead.
6766 (No_Overlap): Removed, model functions should be used instead.
6767 (Equivalent_Keys): Functions over cursors are removed. They were
6768 awkward with explicit container parameters.
6769 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6770 allow the use of regular equality over elements in contracts.
6771 (Formal_Model): Ghost package containing model functions that

6780 * gnat1drv.adb: Code cleanup.
6782 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6784 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6785 attribute reference in a post- condition is the subprogram to
6786 which the condition applies. If the condition is inherited
6787 by a type extension, the prefix becomes a reference to the
6788 inherited operation, but there is no need to create a wrapper
6789 for this operation, because 'Result is expanded independently
6790 when elaborating the postconditions.
6792 2017-04-27 Bob Duff <duff@adacore.com>
6794 * sinput.adb: Minor code cleanup.
6795 * namet.adb (Append): Create faster versions of
6796 Append(String) and Append(Name_Id) by using slice assignment
6798 * sem_util.adb (In_Instance): Speed this up by removing
6799 unnecessary tests; Is_Generic_Instance is defined for all
6801 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6802 Remove unused function.
6803 * alloc.ads (Nodes_Initial): Use a much larger value, because
6804 the compiler was spending a lot of time copying the nodes table
6805 when it grows. This number was chosen in 1996, so is rather out
6806 of date with current memory sizes. Anyway, it's virtual memory.
6807 Get rid of Orig_Nodes_...; use Node_... instead.
6808 * atree.adb (Lock): Do not release the Nodes tables; it's a
6810 Orig_Nodes_ ==> Nodes_
6811 * nlists.adb: Orig_Nodes_ ==> Nodes_
6812 * g-table.adb: Remove unused "with" clause.
6813 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6814 not be used by clients.
6815 * g-dyntab.adb (Last_Allocated): New function
6816 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
6818 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6820 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
6822 (Subtypes_Statically_Match): Remove duplicate check.

6842 processing for Ada 83 and instances.
6843 (Object_Access_Level): Merge the processing for indexed components
6844 and selected components.

6856 of Expand_Dispatching_Call. If the denoted subprogram has a
6857 class-wide precondition, this is the only precondition that
6858 applies to the call, rather that the class-wide preconditions
6859 that may apply to the body that is executed. (This is specified
6862 2017-04-27 Yannick Moy <moy@adacore.com>
6864 * gnat1drv.adb (Adjust_Global_Switches): Issue
6865 a warning in GNATprove mode if the runtime library does not
6866 support IEEE-754 floats.

6870 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6871 is itself inherited it does not carry any contract information,
6872 so examine its parent operation which is its Alias.
6874 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6876 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6877 prefix can be an object reference in which case Obj'Image (X)
6878 can only be interpreted as an indexing of the parameterless
6879 version of the attribute.
6880 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6881 an indexing or a slice operation if the attribute does not require
6882 parameters. In Ada2012 'Image also belongs in this category,
6883 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6885 2017-04-27 Yannick Moy <moy@adacore.com>
6887 * exp_ch4.adb: Minor reformatting.
6888 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
6889 disable the CodePeer and C generation modes. Similar to the
6890 opposite actions done in CodePeer mode.

7429 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
7430 in gnat1 and gnatbind.
7431 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
7432 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

7440 modifications in functional containers.
7441 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7442 to improve readablity. Subprograms are separated between basic
7443 operations, constructors and properties. Universally quantified
7444 formulas in contracts are factorized in independant functions
7445 with a name and a comment. Names of parameters are improved.
7447 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7449 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7451 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7453 * sem_res.adb (Resolve_Type_Conversion): Do not
7454 install a predicate check here since this is already done during
7455 the expansion phase. Verify whether the operand satisfies the
7456 static predicate (if any) of the target type.
7457 * sem_ch3.adb (Analyze_Object_Declaration): Do
7458 not install a predicate check if the object is initialized by
7459 means of a type conversion because the conversion is subjected
7462 2017-04-27 Tristan Gingold <gingold@adacore.com>
7464 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
7465 replaced by their variants).

7476 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
7479 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7481 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7482 the loop which detects potential enclosing transient scopes. The
7483 loop now terminates much earlier as transient scopes are bounded
7484 by packages and subprograms.
7486 2017-04-27 Claire Dross <dross@adacore.com>
7488 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7489 allow the use of regular equality over elements in contracts.
7490 (Cursor): Type is now public so that it can be used in
7492 (Formal_Model): Ghost package containing
7493 model functions that are used in subprogram contracts.
7494 (Current_To_Last): Removed, model functions should be used
7496 (First_To_Previous): Removed, model functions should
7498 (Strict_Equal): Removed, model functions
7499 should be used instead.
7500 (Append): Default parameter value
7501 replaced by new wrapper to allow more precise contracts.
7502 (Insert): Default parameter value replaced by new wrapper to
7503 allow more precise contracts.

7505 value replaced by new wrapper to allow more precise contracts.
7506 (Prepend): Default parameter value replaced by new wrapper to
7507 allow more precise contracts.
7508 (Delete_First): Default parameter
7509 value replaced by new wrapper to allow more precise contracts.
7510 (Delete_Last): Default parameter value replaced by new wrapper

7519 Default_Initial_Condition procedure of a type under the SPARK
7520 elaboration checks umbrella.
7522 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7524 * sem.adb (Analyze): Diagnose an illegal iterated component
7526 * sem_util.ads, sem_util.adb

7531 * adaint.c (__gnat_get_current_dir): Return 0 in length if
7533 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7534 exception if getcwd failed.
7536 2017-04-27 Yannick Moy <moy@adacore.com>

7539 entities with special prefix.
7541 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7543 * debug.adb Change the documentation of switch -gnatd.s.
7544 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7545 to manage the secondary stack when an enclosing scope already
7546 performs this functionality (aka relaxed management). Switch
7547 -gnatd.s may be used to force strict management in which case
7548 the block will manage the secondary stack unconditionally. Add
7549 a guard to stop the traversal when encountering a package or a
7552 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7554 * sem_res.adb (Resolve_Call): Refine further the handling of
7555 limited views of return types in function calls. If the function
7556 that returns a limited view appears in the current unit,
7557 we do not replace its type by the non-limited view because
7558 this transformation is performed int the back-end. However,
7559 the type of the call itself must be the non-limited view, to
7560 prevent spurious resolution errors.
7562 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7564 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7565 Removed, proposed implementation using generics for class-wide
7566 preconditions proved impractical.
7567 (Class_Wide_Clone): New attribute of subprogram. Designates
7568 subprogram created for primitive operations with class-wide
7569 pre/postconditions that contain calls to other primitives. The
7570 clone holds the body of the original primitive, but the
7571 pre/postonditions do not apply to it. The original body is
7572 rewritten as a wrapper for a call to the clone.
7573 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7574 the flag is set, no code for the corresponding pre/postconditions
7575 is inserted into its body.
7577 2017-04-27 Bob Duff <duff@adacore.com>
7579 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
7580 Scalar_Storage_Order if -gnatI is given.
7581 * sem_prag.adb (Analyze_Pragma): Ignore
7582 Default_Scalar_Storage_Order if -gnatI is given.

7591 (Remove): New function that removes an element from a set.
7592 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
7593 (Remove): New function that removes an element from a sequence.
7594 (Insert): New function that adds anywhere in a sequence.

7607 of attribute 'Result is not considered a violation of pragma
7610 2017-04-27 Justin Squirek <squirek@adacore.com>
7612 * cstand.adb (Create_Standard): Correctly set

7623 private child of Ada.Containers used to implement all functional
7625 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7626 child of Ada.Containers. It provides functional indefinite unbounded
7627 maps which can be used as high level models for specification
7629 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7630 child of Ada.Containers. It provides functional indefinite unbounded
7631 sets which can be used as high level models for specification
7633 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7634 child of Ada.Containers. It provides functional indefinite unbounded
7635 vectors which can be used as high level models for specification
7637 * Makefile.rtl: Add new packages.
7638 * impunit.adb: Add new packages.
7640 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7642 * sem_ch4.adb: Minor reformatting.
7644 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7646 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7647 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7648 point type actual that has user-defined arithmetic primitives,
7649 when there is a previous actual for a formal package that defines
7650 a fixed-point type with the parent user-defined operator.
7652 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7654 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7655 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7656 the component type allows range checks.
7658 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7660 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7661 corresponding declaration, because formal derived types are
7662 rewritten as private extensions.
7664 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7666 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7667 dimensions of operands if node has been analyzed already, because
7668 previous analysis and dimension checking will have removed the
7669 dimension information from the operands.
7671 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7673 * debug.adb: Document the use of switch -gnatd.s.
7674 * einfo.ads Update the documentation on attribute
7675 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7676 the uses of these attributes from certain entities.

7678 which determines whether the block should continue to manage
7679 the secondary stack.

7733 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7734 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7735 Ada_2012 instead of Ada_2005 to be compatible with the above
7737 * bindgen.adb: Silence new warning on pragma Ada_95.
7739 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7752 Fix spelling mistakes.
7754 2017-04-25 Bob Duff <duff@adacore.com>
7756 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7757 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7758 for source buffers. Fix misc obscure bugs.
7759 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7760 checking, for source buffers. Modify representation clause for
7761 Source_File_Record as appropriate. Move Source_File_Index_Table
7762 from spec to body, because it is not used outside the body.
7763 Move Set_Source_File_Index_Table into the private part, because
7764 it is used only in the body and in children. Use trickery to
7765 modify the dope in the generic instantiation case. It's ugly,
7766 but not as ugly as the previous method. Fix documentation.
7767 Remove obsolete code.

7783 expander is not active or when index/range checks are suppressed
7785 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7786 Remove variants that include a Supress parameter. These routines
7787 are never used, and were introduced before the current scope-based
7788 check suppression method.

7818 error on the return type of an expression function that is a
7819 completion, if the type is derived from a generic formal type.
7821 2017-04-25 Ed Schonberg <schonberg@adacore.com>

7839 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7840 the Internal_Source buffer. This removes the incorrect call to "="
7841 the customer noticed.
7842 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7843 eventually need to eliminate them altogether. Or else get rid
7844 of zero-origin addressing.

8123 * exp_attr.adb (Expand_Attribute_Reference, case 'Read):
8124 If the type is an unchecked_union, replace the attribute with

8128 further expansion for the unchecked union.
8129 (Expand_Attribute_Reference, case 'Write): If the type is
8130 an unchecked_union, check whether enclosing scope is a Write
8131 subprogram. Replace attribute with a Raise_Program_Error if the
8132 discriminants of the unchecked_union type have not default values
8133 because such a use is erroneous..

8220 When resolving against any fixed type, set the type of the
8221 operand as universal real when the operand is a multiplication
8222 or a division where both operands are of any fixed type.
8223 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the
8224 placement of an error message by pointing to the operand of a
8225 type conversion rather than the conversion itself.
8227 2017-04-25 Thomas Quinot <quinot@adacore.com>
8229 * sem_ch13.adb (Build_Predicate_Function_Declaration): Set

8295 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
8296 overlap if the two formals have different types, because formally
8297 the corresponding actuals cannot designate the same objects.
8299 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8301 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
8302 dimensions are present from context, use them. b) If operand is
8303 a static constant rewritten as a literal, obtain the dimensions

8330 * exp_util.adb: Minor reformatting.
8332 2017-04-25 Justin Squirek <squirek@adacore.com>
8334 * exp_ch3.adb (Freeze_Type): Add condition to always treat
8335 interface types as a partial view of a private type for the
8336 generation of invariant procedure bodies.
8337 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
8338 Add a condition to get the Corresponding_Record_Type for
8339 concurrent types, add condition to return in the absence of a

8341 and add call to Replace_References.
8342 (Add_Interface_Invariatns),
8343 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
8344 to including the working type T.
8345 (Add_Own_Invariants): Remove
8346 legacy condition for separate units, remove dispatching for ASIS
8347 and save a copy of the expression in the pragma expression.
8348 (Build_Invariant_Procedure_Body): Default initalize vars,
8349 remove return condition on interfaces, always use the
8350 private type for interfaces, and move the processing of types
8351 until after the processing of invariants for the full view.
8352 (Build_Invariant_Procedure_Declaration): Remove condition
8353 to return if an interface type is encountered and add
8354 condition to convert the formal parameter to its class-wide
8355 counterpart if Work_Typ is abstract.
8356 (Replace_Type): Add call to Remove_Controlling_Arguments.
8357 (Replace_Type_Ref): Remove class-wide dispatching for the current
8358 instance of the type.
8359 (Replace_Type_References): Remove parameter "Derived"
8360 (Remove_Controlling_Arguments): Created in order to removing
8361 the controlliong argument from calls to primitives in the case
8362 of the formal parameter being an class-wide abstract type.
8363 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
8364 to the change made to Freeze_Type in exp_ch3. Add a condition
8365 to treat interface types as a partial view.
8366 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
8367 to Build_Invariant_Procedure_Declaration to properly generate a
8368 "partial" invariant procedure when Typ is an interface.

8372 * a-numeri.ads: Go back to using brackets encoding for the Greek
8375 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8377 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8378 (10-15): if derived type T with progenitors is abstract,
8379 and primitive P of this type inherits non-trivial classwide
8380 preconditions from both a parent operation and from an interface
8381 operation, then the inherited operation is abstract if the parent
8382 operation is not null.
8383 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8384 with Covered_Interface_Op to yield the actual interface operation
8385 that is implemented by a given inherited operation.

8412 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8413 dereference is introduced for the object, and the object is
8414 overloaded, do not check whether it is aliased, because it may
8415 include an implicit dereference.
8416 * sem_type.adb (Disambiguate): If two interpretations are access
8417 attribute types with the same designated type keep either of
8418 them and do not report an ambiguity. A true ambiguity will be
8421 2017-04-25 Bob Duff <duff@adacore.com>
8423 * a-numeri.ads: Change the encoding of Greek letter Pi from
8424 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8425 to indicate the encoding. We considered using a byte order mark
8426 (BOM), but that causes various trouble (misc software eats the
8427 BOM, if you have a patch with a BOM, then it's not at the start

8472 enforce legality rule on classwide preconditions inherited from
8473 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8474 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8475 subprogram need not be dispatching if it appears in a precondition
8476 for an abstract or null subprogram.
8478 2017-04-25 Gary Dismukes <dismukes@adacore.com>

8484 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
8486 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8488 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
8489 have a length which is a power of 2.
8490 (Is_Predefined_File_Name): Likewise. Adjust comment.
8492 2017-04-25 Bob Duff <duff@adacore.com>
8494 * exp_aggr.adb (Component_Count): Protect the
8495 arithmetic from attempting to convert a value >= 2**31 to Int,
8496 which would otherwise raise Constraint_Error.
8498 2017-04-25 Bob Duff <duff@adacore.com>
8500 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8501 first character of the policy name is not unique.

8524 Save and restore the value of global flag
8525 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
8526 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
8527 the corresponding spec or the body must ignore all SPARK_Mode
8528 pragmas found within.
8529 (Analyze_Subprogram_Declaration): Mark
8530 the spec when it needs to ignore all SPARK_Mode pragmas found
8531 within to allow the body to infer this property in case it is
8532 instantiated or inlined later.
8533 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8534 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8535 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8536 when the corresponding spec also ignored all SPARK_Mode pragmas
8538 (Analyze_Package_Declaration): Mark the spec when
8539 it needs to ignore all SPARK_Mode pragmas found within to allow

8547 property in case it is instantiated or inlined later.
8548 (Analyze_Package_Instantiation): Save and restore the value
8549 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8550 the instance spec when it needs to ignore all SPARK_Mode

8569 Ignore_Pragma_SPARK_Mode.
8570 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8571 all SPARK_Mode pragmas defined within yields mode "off".
8573 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

8592 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8594 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8595 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8596 variable and set it to True whenever the main hash table is
8597 populated. Short- circuit the Assoc function if it is false
8598 and add associated guards.
8600 2017-04-25 Olivier Hainque <hainque@adacore.com>
8602 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8603 specs without elaboration code that have an elaboration counter
8604 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8605 * sem_ch10.adb (Analyze_Compilation_Unit):
8606 Set_Elaboration_Entity_Required when requested to preserve
8607 control flow, to ensure the unit elaboration is materialized at
8608 bind time, resulting in the inclusion of the unit object file
8609 in the executable closure at link time.
8611 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8613 * exp_dbug.adb: In Debug_Renaming_Declaration,
8614 when dealing with indexed component, accept to produce a renaming
8615 symbol when the index is an IN parameter or when it is a name
8616 defined in an outer scope.
8618 2017-04-25 Yannick Moy <moy@adacore.com>
8620 * errout.adb (Error_Msg): Adapt continuation
8621 message in instantiations and inlined bodies for info messages.
8623 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8625 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8626 Use direct 4-character slice comparisons.
8628 pragma Inline. (Has_Suffix): Delete.
8629 (Is_Internal_File_Name):
8630 Test Is_Predefined_File_Name first.
8631 (Is_Predefined_File_Name):

8635 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8637 * checks.adb (Insert_Valid_Check): Code cleanup.
8638 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8639 (Expand_Actuals): Generate proper copy-back for a validation
8640 variable when it acts as the argument of a type conversion.
8641 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8642 predicate to operate on type qualifications.
8644 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8646 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8649 2017-04-25 Bob Duff <duff@adacore.com>
8651 * sem_prag.adb (No_Return): Give an error if the pragma applies
8652 to a body. Specialize the error for the specless body case,
8653 as is done for (e.g.) pragma Convention.
8654 * debug.adb: Add switch -gnatd.J to disable the above legality
8655 checks. This is mainly for use in our test suite, to avoid
8656 rewriting a lot of illegal (but working) code. It might also
8657 be useful to customers. Under this switch, if a pragma No_Return
8658 applies to a body, and the procedure raises an exception (as it
8659 should), the pragma has no effect. If the procedure does return,
8660 execution is erroneous.
8662 2017-04-25 Bob Duff <duff@adacore.com>
8664 * exp_ch6.adb (Expand_Actuals): This is the
8665 root of the problem. It took N as an 'in out' parameter, and in
8666 some cases, rewrote N, but then set N to Original_Node(N). So
8667 the node returned in N had no Parent. The caller continued
8668 processing of this orphaned node. In some cases that caused a
8669 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8670 and trips over the Empty Parent). The solution is to make N an
8671 'in' parameter. Instead of rewriting it, return the list of
8672 post-call actions, so the caller can do the rewriting later,
8673 after N has been fully processed.
8674 (Expand_Call_Helper): Move most of Expand_Call here. It has
8675 too many premature 'return' statements, and we want to do the
8676 rewriting on return.
8677 (Insert_Post_Call_Actions): New procedure to insert the post-call
8678 actions in the appropriate place. In the problematic case,
8679 that involves rewriting N as an Expression_With_Actions.
8680 (Expand_Call): Call the new procedures Expand_Call_Helper and
8681 Insert_Post_Call_Actions.
8683 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8685 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8686 properly type derived from generic formal types, to handle
8687 properly modified version of ACATS 4.1B B611017.
8689 2017-04-25 Javier Miranda <miranda@adacore.com>
8691 * exp_unst.adb (Subp_Index): Adding missing
8692 support for renamings and functions that return a constrained
8693 array type (i.e. functions for which the frontend built a
8694 procedure with an extra out parameter).
8696 2017-04-25 Pascal Obry <obry@adacore.com>
8698 * s-string.adb: Minor code clean-up.
8700 2017-04-25 Bob Duff <duff@adacore.com>

8704 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
8705 function for Non_Blocking_Wait_Process.
8707 2017-04-25 Bob Duff <duff@adacore.com>
8709 * prep.adb (Preprocess): Remove incorrect
8710 Assert. Current character can be ASCII.CR.
8712 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8714 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8715 convention Stdcall, which has a number of exceptions. Convention
8716 is legal on a component declaration whose type is an anonymous
8717 access to subprogram.
8719 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8721 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8722 (Try_One_Prefix_Interpretation): Use the base type when dealing
8723 with a subtype created for purposes of constraining a private
8724 type with discriminants.
8726 2017-04-25 Javier Miranda <miranda@adacore.com>
8728 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
8729 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
8730 dispatching primitives (Restore_Warnings): Restore warning on
8731 late dispatching primitives (Save_Warnings): Save warning on late
8732 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8733 to enable/disable this warning.
8734 (WA_Warnings): Set warning on late dispatching primitives.
8735 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8736 that its parent type has a private extension.
8737 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8739 * usage.adb: Document -gnatw.j and -gnatw.J.
8741 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8743 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8746 2017-04-25 Bob Duff <duff@adacore.com>
8748 * binde.adb (Validate): Do not pass dynamic strings
8749 to pragma Assert, because older compilers do not support that.
8751 2017-04-25 Bob Duff <duff@adacore.com>
8753 * s-fileio.adb (Close): When a temp file is
8754 closed, delete it and clean up its Temp_File_Record immediately,
8755 rather than waiting until later.
8756 (Temp_File_Record): Add File
8757 component, so Close can know which Temp_File_Record corresponds
8758 to the file being closed.
8759 (Delete): Don't delete temp files,
8760 because they are deleted by Close.
8761 (Open): Set the File component
8762 of Temp_File_Record. This requires moving the creation of the
8763 Temp_File_Record to the end, after the AFCB has been created.
8765 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8767 * checks.adb (Insert_Valid_Check): Do not generate
8768 a validity check when inside a generic.
8770 2017-04-25 Yannick Moy <moy@adacore.com>
8772 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
8774 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8776 * snames.ads-tmpl (Snames): More names for detecting predefined
8777 potentially blocking subprograms.
8779 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8781 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
8782 concerning inheritance of class-wide preconditions do not apply
8785 2017-04-25 Bob Duff <duff@adacore.com>
8787 * s-ficobl.ads: Minor comment fix.
8789 2017-04-25 Yannick Moy <moy@adacore.com>
8791 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8792 conversions from float to integer in GNATprove mode.
8793 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8794 to call Apply_Type_Conversion_Checks, so that range checks
8795 are properly positioned when needed on conversions, including
8796 when converting from float to integer. (Determine_Range): In
8797 GNATprove mode, take into account the possibility of conversion
8798 from float to integer.
8799 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8800 check on conversions from fixed-point to integer, not anymore
8801 on conversions from floating-point to integer, when in GNATprove
8804 2017-04-25 Yannick Moy <moy@adacore.com>
8806 * checks.adb (Determine_Range_R): Special case type conversions
8807 from integer to float in order to get bounds in that case too.
8808 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8809 mode, for computations involved in interval checking.

8821 (Validated_Object): New routine along with pragma Inline.
8822 (Set_Validated_Object): New routine along with pragma Inline.
8823 * exp_attr.adb (Make_Range_Test): Add processing for validation
8824 variables to avoid extra reads and copies of the prefix.
8825 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8826 variables in order to reflect any changes done in the variable
8827 back into the original object.
8828 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8829 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8835 generate Finalize_Address routines for CodePeer.
8837 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8839 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8840 Analyze_Pre_Post_Condition, to implement the legality checks
8841 mandated by AI12-0131: Pre'Class shall not be specified for an
8842 overriding primitive subprogram of a tagged type T unless the
8843 Pre'Class aspect is specified for the corresponding primitive
8844 subprogram of some ancestor of T.
8846 2017-04-25 Bob Duff <duff@adacore.com>
8848 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8849 is redundant, set its Used_Operations to empty. This is only
8850 necessary for use clauses that appear in the parent of a generic
8851 child unit, because those use clauses get reanalyzed when we
8852 instantiate the generic, and we don't want the Used_Operations
8853 carried over from the original context (where it was probably
8856 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8858 * exp_ch6.adb: Minor reformatting.

8866 * par.adb (Par): Null out Current_Source_File, to ensure that
8867 the above bugs won't rear their ugly heads again.
8869 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8871 * sem_ch8.adb (Find_Type): For an attribute reference
8872 'Class, if prefix type is synchronized and previous errors
8873 have suppressed the creation of the corresponding record type,
8874 create a spurious class-wide for the synchonized type itself,
8875 to catch other misuses of the attribute
8877 2017-04-25 Steve Baird <baird@adacore.com>
8879 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
8880 is True, then don't generate the accessibility check for the
8881 tag of a tagged result.
8882 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
8883 if CodePeer_Mode is True, then don't generate the
8884 tag checks for the result of call to an instance of
8885 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8886 descendant of" check and the accessibility check).
8888 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8890 * sem_ch13.adb: Code cleanups.
8891 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

8896 * exp_ch4.adb (Library_Level_Target): New function.
8897 (Expand_Concatenate): When optimization is enabled, also expand
8898 the operation out-of-line if the concatenation is present within
8899 the expression of the declaration of a library-level object and
8900 not only if it is the expression of the declaration.
8902 2017-04-25 Bob Duff <duff@adacore.com>
8904 * freeze.adb (Freeze_Object_Declaration): Do
8905 not Remove_Side_Effects if there is a pragma Linker_Section,
8906 because in that case we want static initialization in the
8907 appropriate section.
8909 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8911 * exp_dbug.adb: Minor rewording and reformatting.
8913 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8915 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8916 handle the proposed changes to rules concerning potentially
8917 unevaluated expressions, to include selected components that
8918 do not depend on discriminants, and indexed components with
8920 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8921 predicate in quantified expression, and fix bugs in the handling
8922 of case expressions and membership test.
8923 (Analyze_Attribute_Old_Result): use new predicate.
8924 (Analyze_Attribute, case Loop_Entry): ditto.
8926 2017-04-25 Bob Duff <duff@adacore.com>
8928 * s-secsta.adb (SS_Info): Add a comment

8965 internal calls that appear in preconditions of protected
8966 operations, in default values for same, and in contract guards
8967 for contract cases in SPARK.

8979 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8980 (Reduce): Adjust and complete description. Call Is_Nan instead of
8981 testing manually. Use an integer temporary to hold rounded value.
8982 * a-numaux-darwin.adb (Reduce): Likewise.
8983 (Is_Nan): New function.
8985 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8987 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8988 on analysis of prefix whose type is a current instance of a

8994 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8995 the identity of callable entities therein, because they have been
8996 properly resolved, and prefixed calls may have been rewritten
8999 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9001 * exp_ch3.adb (Build_Init_Statements): Convert
9002 the expression of the pragma/aspect Secondary_Stack_Size to

9017 2017-04-25 Javier Miranda <miranda@adacore.com>
9019 * urealp.adb (UR_Write): Reverse previous patch
9020 adding documentation on why we generate multiplications instead
9021 of divisions (needed to avoid expressions whose computation with
9022 large numbers may cause division by 0).
9024 2017-04-25 Bob Duff <duff@adacore.com>
9026 * erroutc.adb (Set_Specific_Warning_Off,
9027 Set_Warnings_Mode_Off): Use the correct source file for
9028 Stop. Was using Current_Source_File, which is only valid during
9029 parsing. Current_Source_File will have a leftover value from
9030 whatever file happened to be parsed last, because of a with_clause
9033 2017-04-25 Bob Duff <duff@adacore.com>
9035 * lib.ads, lib.adb (In_Internal_Unit): New functions similar

9037 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9038 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9039 because Should_Ignore_Pragma was not working reliably outside
9040 the parser, because Current_Source_File is not valid.
9041 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9042 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9106 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9109 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9111 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9112 of prefix whose type is a current instance of a synchronized
9113 type. If the prefix is an object this is an external call (or
9114 requeue) that can only access public operations of the object. The
9115 previous predicate was too restrictive, and did not allow public
9116 protected operations, only task entries.
9118 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9120 * sem_ch5.adb, fname.adb: Minor reformatting.
9122 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9124 * einfo.adb (Is_Anonymous_Access_Type): New routine.
9125 * einfo.ads Update the placement of
9126 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9128 (Is_Anonymous_Access_Type): New routine.
9129 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9130 master for an access type subject to pragma No_Heap_Finalization.
9131 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9132 allocated or deallocated does not finalization actions if the
9133 associated access type is subject to pragma No_Heap_Finalization.
9134 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9135 * par-prag.adb Pragma No_Heap_Finalization does not need special
9136 processing from the parser.
9137 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9138 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9139 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9140 No_Heap_Finalization.
9141 (Analyze_Pragma): Add processing for
9142 pragma No_Heap_Finalization. Update various error messages to
9143 use Duplication_Error.
9144 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9145 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9146 and corresponding pragma id.

9150 * freeze.adb (Freeze_Record_Type): Use the
9151 underlying type of the component type to determine whether it's
9152 elementary. For representation clause purposes, a private type
9153 should behave the same as its full type.
9154 * fname.ads, fname.adb (Is_Predefined_File_Name):
9155 Make sure things like "system.ali" are recognized as predefined.
9157 2017-04-25 Javier Miranda <miranda@adacore.com>

9163 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9164 element iterator when the name is an overloaded function call,
9165 one of whose interpretations yields an array.
9167 2017-04-25 Bob Duff <duff@adacore.com>
9169 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9170 Is_Internal_Unit_Name): New functions for operating on unit
9171 names, as opposed to file names. There's some duplicated code
9172 with fname.adb, which is unfortunate, but it seems like we don't
9173 want to add dependencies here.
9174 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9175 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9176 is not a file name at all.
9177 * fname.ads, fname.adb: Document the fact that
9178 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9179 for ALI files, and fix the code so it works properly for ALI
9180 files. E.g. these should return True for "system.ali".
9182 2017-04-25 Justin Squirek <squirek@adacore.com>
9184 * exp_util.adb (Add_Invariant): Removed,
9185 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9186 and Add_Own_Invariant. (Add_Invariant_Check): Used
9187 for adding runtime checks from any kind of invariant.
9188 (Add_Inherited_Invariant): Generates invariant checks for
9189 class-wide invariants (Add_Interface_Invariants): Removed, code
9190 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

9193 (Build_Invariant_Procedure_Body): Add refactored calls
9194 and integrated code from Add_Parent_Invariants and
9195 Add_Interface_Invariants.
9196 (Process_Type): Removed, the
9197 relavant code was inlined into both Add_Own_Invariant and
9198 Add_Inherited_Invariant.

9219 and Build_Invariant_Procedure_Declaration.
9220 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9221 and Build_Invariant_Procedure_Declaration from exp_ch7
9222 and break-out Is_Untagged_Private_Derivation from
9223 Build_Invariant_Procedure_Body.
9224 (Replace_Type_References):
9225 Append an extra parameter to allow for dispatching replacements
9226 and add the corrasponding logic.
9227 (Type_Invariant): Remove
9228 Replace_Typ_Refs and replace its references with calls to
9229 Replace_Type_References.
9230 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9232 2017-04-25 Bob Duff <duff@adacore.com>
9234 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9235 that returns True when appropriate.
9236 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9237 when compiling predefined files.
9238 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9239 "gnat.adc" should not be considered a predefined file name.
9240 That required (or at least encouraged) a lot of cleanup of global
9241 variable usage. We shouldn't be communicating information via
9242 the global name buffer.
9243 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9244 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9264 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
9265 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
9266 Add String_To_Name with no side effects.
9268 2017-04-25 Justin Squirek <squirek@adacore.com>
9270 * sem_ch3.adb (Analyze_Declarations): Add
9271 additional condition for edge case.

9275 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
9276 reserved words inside pragmas. This is necessary to allow the
9277 pragma name Interface to be used in pragma Ignore_Pragma.

9303 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9304 the first pass over an assignment statement with target names,
9305 to prevent the generation of subtypes (such as discriminated
9306 record components)that may carry the target name outside of the

9308 the assignment is reanalyzed in full.
9309 (Analyze_Target_Name): Handle properly class-wide types.

9341 properties of the private type to the full view in case the full
9342 view derives from a parent type and inherits a DIC pragma.
9343 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9344 DIC pragma is placed at the top of a declarative region.
9346 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
9348 * a-tasatt.adb: Complete previous change and use an unsigned
9349 int to avoid overflow checks.

9354 the error message when the attribute reference is an actual in
9355 a call to a subprogram inherited from a generic formal type with
9356 unknown discriminants, which makes the subprogram and its formal
9357 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9359 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9361 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9366 * sem_attr.adb (Type_Key): Add code in the
9367 recursive Compute_Type_Key to protect against fetching the source
9368 code for Standard, in case a component of the type is declared
9369 in Standard. There was already code to do this for the original
9370 type, but not for its components.
9372 2017-04-25 Javier Miranda <miranda@adacore.com>
9374 * exp_ch3.adb (Build_Initialization_Call): Handle
9375 subtypes of private types when searching for the underlying full

9391 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
9392 context is a package declaration.
9393 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,

10067 remove certain classes of clauses which are considered noise.
10068 (Check_Dependency_Clause): Properly detect a match between two
10069 'Result attributes. Update the various post-match cases to use

10073 (Remove_Extra_Clauses): New routine.
10074 (Report_Extra_Clauses): Remove the detection of ... => null
10075 clauses as this is now done in Remove_Extra_Clauses.
10077 2017-01-23 Ed Schonberg <schonberg@adacore.com>
10079 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10080 report on spurious overlaps between values involving a subtype
10081 with a static predicate, because the expansion of such a subtype
10082 into individual ranges in inhibited in ASIS mode.

10114 to the expected type with the appropriate check flags set.
10115 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10116 base type if the range is null. It may still be invalid if it
10117 is higher than the lower bound. This is checked later in the

10133 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10134 an object declaration for an array type with a modular index type
10135 with the size of Long_Long_Integer. Special processing is needed
10136 in this case to compute reliably the size of the object, and
10137 eventually to raise Storage_Error, when wrap-around arithmetic
10138 might compute a meangingless size for the object.
10140 2017-01-23 Justin Squirek <squirek@adacore.com>
10142 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10147 * sem_res.adb (Resolve_Call): In the part of the code where
10148 it is deciding whether to turn the call into an indexed
10149 component, avoid doing so if the call is to an instance of
10150 Unchecked_Conversion. Otherwise, the compiler turns it into an
10151 indexed component, and resolution of that turns it back into a
10152 function call, and so on, resulting in infinite recursion.
10153 * sem_util.adb (Needs_One_Actual): If the first formal has a
10154 default, then return False.
10156 2017-01-21 Eric Botcazou <ebotcazou@adacore.com>

10199 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10201 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10202 must be treated as delayed aspect even if the expression is
10203 a literal, because the aspect affects the freezing and the
10204 elaboration of the object to which it applies.

10253 2017-01-20 Javier Miranda <miranda@adacore.com>
10255 * sem_res.adb (Resolve_Call): If a function call
10256 returns a limited view of a type and at the point of the call the
10257 function is not declared in the extended main unit then replace
10258 it with the non-limited view, which must be available. If the
10259 called function is in the extended main unit then no action is
10260 needed since the back-end handles this case.

10282 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10283 When inheriting the SPARK_Mode of a prior expression function,

10374 * sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
10375 aspect Implicit_Dereference can be inherited by a full view if
10376 the partial view has no discriminants, because there is no way
10377 to apply the aspect to the partial view.
10378 (Build_Derived_Record_Type): If derived type renames discriminants

10470 * sem_prag.adb (Analyze_Pragma): Check for ignored pragmas first,
10471 before checking for unrecognized pragmas.

10488 not add the component invariants to the record type invariant
10489 procedure so that the procedure can be used to check the record
10490 type invariants if any.

10512 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
10513 type, ie. a type whose component is a character type, and the
10514 aggregate is positional, do not convert into a string literal
10515 if the index type is not an integer type, because the original
10516 type may be required in an enclosing operation.
10518 2017-01-19 Bob Duff <duff@adacore.com>
10520 * binde.adb, debug.adb: Enable new elaboration order algorithm

10566 * exp_ch6.adb (Expand_Call): Remove side effects on
10567 actuals that are allocators with qualified expression since the
10568 initialization of the object is performed by means of individual
10569 statements (and hence it must be done before the call).
10571 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10573 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10574 (Build_Derived_Enumeration_Type): If the derived type inherits a
10575 dynamic predicate from its parent, the bounds of the type must
10576 freeze because an explicit constraint is constructed for the
10577 type and the corresponding range is elaborated now.
10579 2017-01-19 Arnaud Charlet <charlet@adacore.com>

10615 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10616 in case of generic formal discrete types, because it causes crashes in

10628 wrong since we just issued a warning message.
10629 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10630 these variables to be of subtype Nat instead of Int, because
10631 they should never be negative.

10662 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10664 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10665 selected component has a prefix that might be interpreted
10666 as a parameterless function call, but none of the candidate
10667 interpretations is parameterless, and there is a hidden homonym
10668 of the prefix that is a package.
10669 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10670 interpreted as a parameterless function call and its analysis
10671 fails, do not call Analyze_Selected_Component.
10673 2017-01-19 Steve Baird <baird@adacore.com>
10675 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10677 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with

10682 * gnat1drv.adb: minor fix of unbalanced parens in comment
10683 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10684 to visible part of the package to allow re-use in GNATprove.
10685 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10686 from repeated code of Traverse_Compilation_Unit.
10687 (Traverse_Declaration_Or_Statement): fixed detection of
10688 generic subprograms and packages; also, iteration over case
10689 statement alternatives rewritten to avoid testing if the first
10690 alternative is present (since it must be present due to Ada
10691 syntax restrictions).
10693 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10695 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
10696 returning by reference not just for subprogram body stubs,
10697 but for all subprogram cases.
10698 * sem_util.adb: Code reformatting.
10699 (Requires_Transient_Scope): Update the call to Results_Differ.

10705 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10706 identifier nodes that do not come from source, to handle properly
10707 dimensionality check within an inlined body which inclddes both
10708 original operands and rewritten operands. This removes spurious
10709 dimensionality errors in the presence of front-end inlining,
10710 as well as in SPARK mode.
10712 2017-01-16 Jakub Jelinek <jakub@redhat.com>

10751 * scil_ll.adb: Minor style fix in comment.
10752 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10753 even if entity is already set, because the node may be renalyzed
10754 after inlining transformations.
10756 2017-01-13 Javier Miranda <miranda@adacore.com>
10758 * sem_res.adb (Resolve_Call): Do not establish a transient scope
10759 for a call to inlinable expression function (since the call will

10784 (Freeze_Expr_Types): Complete previous patch since the expression
10785 of an expression-function may have iterators and loops with
10786 defining identifiers which, as part of the preanalysis of the
10787 expression, may be left decorated with itypes that will not be

10830 * binde.adb (Elab_New): New elaboration order algorithm
10831 that is expected to cause fewer ABE issues. This is a work in
10832 progress. The new algorithm is currently disabled, and can be
10833 enable by the -dp switch, or by modifying the Do_Old and Do_New
10834 etc. flags and rebuilding. Experimental code is included to
10835 compare the results of the old and new algorithms.
10836 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10837 can have multiple of these tables, so the old and new algorithms
10839 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10840 parameter of type array. This avoids the global variable, and
10841 allows bounds checking (which is normally defeated by the tables
10842 packages). It also ensures that the Elab_Order is read-only
10844 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10845 subprograms that need it, as above.
10846 * debug.adb: Document new -dp switch. Modify doc of old -do
10848 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10849 and Bindgen. Move writing of closure (-R and -Ra switches)

10852 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10854 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10855 function is a completion, all entities referenced in the
10856 expression are frozen. As a consequence, a reference to an
10857 uncompleted private type from an enclosing scope is illegal.
10859 2017-01-13 Javier Miranda <miranda@adacore.com>
10861 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10862 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10863 expression function declaration that is a completion, its
10864 expression causes freezing (AI12-0103).
10866 2017-01-13 Vadim Godunko <godunko@adacore.com>

10881 restriction No_Tasking is in effect.
10882 (Build_Master_Renaming): Do not rename a master when restriction
10883 No_Tasking is in effect.

10892 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
10893 Iterated_Component_Association is not static.
10895 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>

10921 * exp_aggr.adb: Use Choice_List throughout, to handle
10922 Iterated_Component_Associations.
10923 (Gen_Loop): Generate proper loop for an
10924 Iterated_Component_Association: loop variable has the identifier
10925 of the original association. Generate a loop even for a single
10926 component choice, in order to make loop parameter visible in
10928 (Flatten): An Iterated_Component_Association is not static.
10930 2017-01-13 Yannick Moy <moy@adacore.com>
10932 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10933 float exponentiation for statically known small negative values
10934 is the reciprocal of the exponentiation for the opposite value
10936 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10937 Ensure that the value of float exponentiation for negative values

10949 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10951 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10952 mode a choice that is a subtype with a static predicate is
10953 replaced by the values it covers. This transformation must not
10954 be performed in ASIS mode, to preserve the source for analysis.
10956 2017-01-13 Justin Squirek <squirek@adacore.com>
10958 * nlists.ads: Correct minor typo.

10970 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10971 and resolve the discrete choices and the expression of the
10973 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10974 Loop_Actions and Box_Present are attributes of
10975 N_Iterated_Component_Association nodes. Box_Present is always
10976 False in this case.
10977 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10978 has a Discrete_Choices list, as specified in the RM. A
10979 Component_Association for aggregate uses instead a Choices list.
10980 We have to live with this small inconsistency because the new
10981 construct also has a defining identifier, and there is no way
10982 to merge the two node structures.

10994 Analyze_Declarations, to analyze and resolve the expressions of
10995 aspect specifications in the current declarative list, so that
10996 the expressions have proper entity and type info. This is needed
10997 for ASIS when there is no subsequent expansion to generate this
10998 semantic information.
10999 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11000 original expression, to suppress cascaded errors when expression
11001 has been constant-folded.
11002 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11003 ASIS mode, because there is no subsequent expansion to decorate
11006 2017-01-13 Yannick Moy <moy@adacore.com>
11008 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11009 New function to detect when a call may be inlined or not in
11011 (Expand_Inlined_Call): Ensure that a temporary
11012 is always created in the cases where a type conversion may be
11013 needed on an input parameter in GNATprove mode, so that GNATprove
11014 sees the check to perform.
11015 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11016 when not applicable due to actual requiring type conversion
11017 with possible check but no temporary value can be copied for
11018 GNATprove to see the check.
