4 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
5 new member of struct attribute_spec.
7 2017-12-06 Simon Wright <simon@pushface.org>
10 * bindgen.adb (Gen_AdaFinal): If the restriction No_Task_Termination is
11 set, generate a null body.
13 2017-12-05 Piotr Trojanek <trojanek@adacore.com>

26 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
28 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
29 QNX. At startup, the first mutex created has a non-zero ceiling
30 priority whatever its actual policy. This makes some tests fail
31 (c940013 for example).
33 2017-12-05 Bob Duff <duff@adacore.com>
35 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
36 Expand_Cleanup_Actions for N_Extended_Return_Statement.
37 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
38 N_Extended_Return_Statement by transforming the statements into a
39 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
40 It's too hard for Expand_Cleanup_Actions to operate directly on the
41 N_Extended_Return_Statement, because it has a different structure than
42 the other node kinds that Expand_Cleanup_Actions.
43 * exp_util.adb (Requires_Cleanup_Actions): Add support for
44 N_Extended_Return_Statement. Change "when others => return False;" to
45 "when others => raise ...;" so it's clear what nodes this function
46 handles. Use named notation where appropriate.
47 * exp_util.ads: Mark incorrect comment with ???.
49 2017-12-05 Javier Miranda <miranda@adacore.com>

77 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
78 subprogram is overloaded, scan the list of homonyms in the same
79 scope, to find the inherited operation that may be overridden
81 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
83 2017-12-05 Bob Duff <duff@adacore.com>
85 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
86 Init_Assignment is rewritten, we need to set Assignment_OK on the new
87 node. Otherwise, we will get spurious errors when initializing via
90 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>

102 2017-12-05 Nicolas Setton <setton@adacore.com>
104 * terminals.c (__gnat_setup_child_communication): As documented,
105 __gnat_setup_child_communication should not terminate - it is intended
106 to be used as the child process of a call to fork(). However, execvp
107 might actually return in some cases, for instance when attempting to
108 run a 32-bit binary on a 64-bit Linux distribution when the
109 compatibility packages are not installed. In these cases, exit the
110 program to conform to the documentation.
112 2017-12-05 Olivier Hainque <hainque@adacore.com>

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

277 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
279 2017-12-05 Javier Miranda <miranda@adacore.com>
281 * checks.adb (Generate_Range_Check): Force evaluation of the node in
282 more cases. This patch was written to improve the code generated by
283 the CCG compiler but it is enabled for all targets since double
284 evaluation is always a potential source of inefficiency.

298 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
299 assignment if it is part of an Iterated_Component_Association: the
300 analysis needs to take place once the loop structure is analyzed and
301 the loop parameter made visible, because references to it typically
302 appear in the corresponding expression. This is necessary if the
303 expression is an aggregate, because previous pre-analysis of the
304 expression does not handle nested aggregates properly.
306 2017-12-05 Bob Duff <duff@adacore.com>
308 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an

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

326 Do not alter the module Low and High (relative) addresses.
327 (Is_Inside): Improve documentation regarding the kinds of addresses
328 at hand and correct the test.
329 (Symbolic_Traceback): Use separate variables with explicit names
330 for the address in traceback (run-time value) and the address to
331 lookup within the shared object (module-relative). Adjust the
332 computation of address passed to Symbolic_Address for symbolization.

337 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
338 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
339 other back-ends can also benefit from the front-end expansion. Remove
340 test for Modify_Tree_For_C in all callers to better share code.
341 * gnat1drv.adb (Adjust_Global_Switches): Set
342 Expand_Nonbinary_Modular_Ops when generating C code.

347 parameter becomes invisible after analyzing the loop, which has been
348 rewritten as a while-loop.

357 * exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
358 instead of the full name.
359 * sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
360 in the case of an instance of a generic.
362 2017-12-05 Arnaud Charlet <charlet@adacore.com>
364 (Adjust_Global_Switches): Create an alias GNAT_Annotate to map to

837 2017-11-09 Pascal Obry <obry@adacore.com>
839 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
840 only for foreign threads. We initialize the thread handle only if not
841 yet initialized. This happens in Enter_Task for foreign threads only.
842 But for native threads (Ada tasking) we do want to keep the real
843 handle (from Create_Task) to be able to free the corresponding
844 resources in Finalize_TCB (CloseHandle).

858 (Make_DT): Declare constant the Interface_Table object associated with
859 an statically built dispatch table. For this purpose the Offset_To_Top
860 value of each interface is computed using the dummy object.
861 * exp_ch3.adb (Build_Init_Procedure): Do not generate code initializing
862 the Offset_To_Top field of secondary dispatch tables when the dispatch
863 table is statically built.

873 to avoid a dormant bug.
875 2017-11-09 Jerome Lambourg <lambourg@adacore.com>
877 * init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
878 as such capability is not available on the OS.

880 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
881 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
882 in particular a workaround with locks priority ceiling where a higher
883 priority task is allowed to lock a lower ceiling priority lock. This
884 also fixes the scheduling of FIFO tasks when the priority of a task is
886 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
888 2017-11-09 Yannick Moy <moy@adacore.com>

892 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
894 * namet.adb (Copy_One_Character): Add assumption for static analysis,
895 as knowledge that Hex(2) is in the range 0..255 is too complex for
897 (Finalize): Add assumption for static analysis, as the fact that there
898 are symbols in the table depends on a global invariant at this point in
900 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
901 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
904 2017-11-09 Javier Miranda <miranda@adacore.com>
906 * libgnat/s-rident.ads (Static_Dispatch_Tables): New restriction name.
907 * exp_disp.adb (Building_Static_DT): Check restriction.

944 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
945 * freeze.adb (Check_Component_Storage_Order): Default initialize
946 Comp_Byte_Aligned rather than silencing messages with pragma
947 Warnings(Off), which does not work for CodePeer initialization
948 messages, and given that here the possible read of an unitialized value
949 depends on a proper use of parameters by the caller.
950 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
951 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
952 * sem_ch3.adb (Build_Derived_Array_Type): Default initialize

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

991 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

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

1003 * sem_ch4.adb (Analyze_Call): Reject a call to a function that returns
1004 a limited view of a type T declared in unit U1, when the function is
1005 declared in another unit U2 and the call appears in a procedure within

1010 * sem_ch8.adb (Analyze_Use_Package): Force installation of use_clauses
1011 when processing generic instances.
1013 2017-11-09 Bob Duff <duff@adacore.com>
1015 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1016 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1017 objects can have those special values. Valid_Name_Id could usefully be
1018 used all over the compiler front end, but that's too much trouble for
1019 now. If we did that, we might want to rename:
1020 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1021 For parameters of type Valid_Name_Id, remove some redundant tests,
1022 including the ones found by CodePeer. Use Is_Valid_Name instead of
1023 membership test when appropriate.
1024 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1025 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1026 "in Error_Name_Or_No_Name".
1027 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in
1028 Error_Name_Or_No_Name".

1037 2017-11-09 Piotr Trojanek <trojanek@adacore.com>
1039 * lib-writ.adb (Write_ALI): Remove processing of the frontend xrefs as
1040 part of the ALI writing; they are now processed directly from memory

2450 2017-10-09 Bob Duff <duff@adacore.com>
2452 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2453 code so if BIPAlloc is not passed in, it will likely raise
2454 Program_Error instead of cause miscellaneous chaos.

2456 as for the other Is_B-I-P... functions.
2457 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2458 aggregate whose ancestor part is a build-in-place call returning a
2459 nonlimited type, transform the assignment to the ancestor part to use a

2462 creating an Itype for a library unit entity.
2463 (Check_Initialization): Avoid spurious error message on
2464 internally-generated call.
2465 * sem_ch5.adb (Analyze_Assignment): Handle the case where the

2469 implies >= Ada 2005.

2510 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2511 limited. This is for the case of a function call that occurs as the
2512 default for a record component.
2513 (Expand_N_Object_Declaration): Deal with the case where expansion has
2514 created an object declaration initialized with something like

2549 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous

2581 (Expand_Simple_Function_Return): Remove assumption that b-i-p implies

2584 (Is_Build_In_Place_Result_Type): New function to accompany
2585 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2586 sometimes we just have the type on our hands, not the function. For
2587 now, does the same thing as the old version, so build-in-place is
2588 disabled for nonlimited types, except that you can use -gnatd.9 to
2590 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2591 accompany Is_Build_In_Place_Function and

2602 Remove assumption that b-i-p implies limited (initialization of
2603 In_Place_Expansion).
2604 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2605 an unchecked conversion. Add assertions.
2606 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2607 secondary stack here, just because the type needs finalization. That

2632 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2633 qualified or converted.
2634 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2635 (Param)) = N_Identifier; that's all it could be.
2636 * sinfo.ads: Comment fixes.
2637 * snames.ads-tmpl: Comment fixes.

2670 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
2671 for types in expression if the function is within a generic unit.
2672 * sem_res.adb (Resolve): In a generic context do not freeze an
2673 expression, unless it is an entity. This exception is solely for the
2674 purpose of detecting illegal uses of deferred constants in generic

3620 2017-09-08 Yannick Moy <moy@adacore.com>
3622 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3623 return the entity associated with the call.
3624 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3625 Replace the internal Get_Function_Id with the new
3626 Sem_Aux.Get_Called_Entity.
3627 (Iterate_Call_Parameters): New
3628 procedure to iterate on formals and actuals at the same time.
3629 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3630 Set SPARK_Mode from spec when set, for analysis
3631 of instance. Restore after analysis of instance.
3632 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3633 set, for analysis of body instance. Restored automatically at
3634 the end of the subprogram.
3635 * gnat1drv.adb (Adjust_Global_Switches): Set
3636 Check_Validity_Of_Parameters to False in GNATprove mode.
3637 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3640 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3642 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3643 (New_Copy_Tree): ...there. Reset the hash tables only if they
3644 were used in the previous invocation.
3645 * s-htable.adb: Fix typo.
3647 2017-09-08 Bob Duff <duff@adacore.com>
3649 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3651 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3653 * sem_aggr.adb: minor style fix.
3655 2017-09-08 Bob Duff <duff@adacore.com>
3657 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3658 no current source file.
3659 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3660 Print something helpful in case N is invalid.
3661 * sprint.ads: Minor comment fix.
3663 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3665 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3668 2017-09-08 Bob Duff <duff@adacore.com>
3670 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3671 Ada_2020, along the same lines as the other Ada version pragmas.
3673 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3675 * sem_ch12.adb: Minor typo fixes and reformatting.
3677 2017-09-08 Yannick Moy <moy@adacore.com>
3679 * sem_aggr.adb (Resolve_Record_Aggregate):
3680 Rewrite bounds of aggregate subexpressions which may depend on
3681 discriminants of the enclosing aggregate.
3683 2017-09-08 Yannick Moy <moy@adacore.com>
3685 * sem_ch5.adb: Prevent assertion failure on illegal code.
3687 2017-09-08 Yannick Moy <moy@adacore.com>
3689 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3690 calling Renamed_Entity on an entity which cannot be a renaming.
3692 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3694 * exp_aggr.adb: Add with & use clause for Urealp.
3695 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3696 elementary types instead of just discrete types.
3697 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3698 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3699 Be prepared for the FP zero value in the memset case. Add small
3702 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3704 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3707 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3709 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3710 of New_Copy because the latter leaves the syntactic structure of
3711 the tree inconsistent (a child is accessible through two parents)
3712 and prevents proper replication of itypes by subsequent calls
3714 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3715 New_Copy because the latter leaves the syntactic structure of the
3716 tree inconsistent (a child is accessible through two parents)
3717 and prevents proper replication of itypes by subsequent calls
3719 * sem_util.adb (In_Subtree): New routine.

3724 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3726 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3727 for aspect Default_Value is a static scalar value, but it does
3728 not freeze the type. Yhis allows for subsequent representation
3729 clauses for the type.
3731 2017-09-08 Javier Miranda <miranda@adacore.com>
3733 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3734 not add entries into the undefined reference table when we are
3735 compiling with errors ignored.
3737 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3739 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3740 check if the instance is within an enclosing instance body. The
3741 formal package was legal in the enclosing generic, and is
3742 legal in the enclosing instantiation. This optimisation may be
3743 applicable elsewhere, and it also removes spurious errors that
3744 may arise with on-the-fly processing of instantiations that
3745 contain Inline_Always subprograms.
3747 2017-09-08 Vincent Celier <celier@adacore.com>
3749 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3751 2017-09-08 Justin Squirek <squirek@adacore.com>
3753 * checks.adb (Insert_Valid_Check): Manually decorate
3754 the generated temporary for range valdity checks.
3756 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3758 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3760 2017-09-08 Justin Squirek <squirek@adacore.com>
3762 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3763 case to handle underscore flags.
3764 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3765 new procedure to handle underscores.
3767 2017-09-08 Javier Miranda <miranda@adacore.com>
3769 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3770 divisions with fixed point results to avoid generating twice
3771 the runtime check on divide by zero.
3772 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3773 not evaluated twice (once for their runtime checks and once for
3774 their regular computation).
3776 2017-09-08 Yannick Moy <moy@adacore.com>
3778 * sem_prag.adb (Analyze_Part_Of): Add missing
3779 return statements after issuing errors. Add detection of
3780 out-of-order item and single concurrent type.

3902 Add support for files in libgnarl.
3904 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3906 * exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
3907 accessibility check to an interface conversion, whose purpose
3908 is to perform a pointer adjustment in a dispatching call.
3909 * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
3910 when the actual is a construct that involves a dereference of an
3911 expression that includes a formal of the enclosing subprogram,
3912 In such cases, the accessibility level of the actual is that of
3913 the corresponding formal, which is passed in as an additional
3914 actual in the outer call.
3916 2017-09-08 Bob Duff <duff@adacore.com>
3918 * exp_intr.adb (Add_Source_Info): Do not decode
3919 file names; they were not encoded in the first place.
3921 2017-09-08 Bob Duff <duff@adacore.com>
3923 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
3924 exceptions instead of crashes. Check for absurdly long strings
3925 and empty strings. Empty strings cause trouble because they can
3926 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3927 be empty, which causes an array index out of bounds.
3928 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
3931 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3933 * sem_util.adb (Is_CCT_Instance): allow use in
3934 the context of protected types.
3936 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3952 * exp_attr.adb (Expand_Loop_Entry_Attribute): Do
3953 not skip a loop coming from source which is rewritten into a loop.
3955 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3957 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
3958 wrapper has convention Ada, to prevent spurious warnings on
3959 unconstrained array parameters.

3982 changes for Include_Subprogram_In_Messages.
3983 * sem_ch5.adb (Check_Unreachable_Code): Supply Node parameter when
3984 generating warning message.
3986 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3988 * par-ch4.adb (P_Iterated_Component_Association): Place construct
3989 under -gnat2020 flag, given that it is a future feature of
3991 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
3992 defining identifier as referenced to prevent spurious warnings:
3993 corresponding loop is expanded into one or more loops whose
3994 variable has the same name, and the expression uses those names
3995 and not the original one.
3997 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3999 * sem_elab.adb (Check_A_Call): Do not consider
4000 references to internal variables for SPARK semantics.

4017 always copy the representation aspects onto the subtype.
4019 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
4021 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
4022 Correction of the return type from access type to option type.

4047 2017-09-08 Javier Miranda <miranda@adacore.com>
4049 * exp_ch6.adb (Unqual_BIP_Function_Call): Adding
4050 missing checks on the presence of Entity() before checking the
4053 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4055 * sem_ch6.adb (Analyze_Expression_Function): Reorder some
4056 statements, use local variable and remove unnecessary processing.

4066 * exp_ch6.adb (Replace_Renaming_Declaration_Id): New
4067 subprogram containing code that was previously inside
4068 Make_Build_In_Place_Call_In_Object_Declaration since it is also

4100 Make_Build_In_Place_Iface_Call_In_Anonymous_Context.
4102 2017-09-08 Javier Miranda <miranda@adacore.com>
4104 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
4105 access to interface types. Remove also the accessibility check.
4107 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4109 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4110 all the types that are referenced by the expression.
4111 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4112 a completion instead of manually freezing the type of the
4114 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4116 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4118 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4119 New procedure, auxiliary to Expand_Pragma_Check, to handle
4120 references to the discriminants of a protected type within a
4121 precondition of a protected operation. This is needed because
4122 the original precondition has been analyzed in the context of
4123 the protected declaration, but in the body of the operation
4124 references to the discriminants have been replaved by references
4125 to the discriminants of the target object, and these references
4126 are only created when expanding the protected body.
4128 2017-09-08 Yannick Moy <moy@adacore.com>
4130 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4133 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4135 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4136 unchecked union, do not emit checks for its (non-existent)
4137 discriminants, or for variant parts that depend on them.
4139 2017-09-08 Justin Squirek <squirek@adacore.com>
4141 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4142 Find_Comparison_Type.Try_One_Interp): Add check for generic
4145 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4147 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4148 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4149 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4150 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4151 remaining references to AAMP_On_Target.
4153 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4155 * style.adb: Fix typo.
4157 2017-09-08 Javier Miranda <miranda@adacore.com>
4159 * einfo.adb (Underlying_Type): Add missing support for class-wide
4160 types that come from the limited view.
4161 * exp_attr.adb (Attribute_Address): Check class-wide type
4162 interfaces using the underlying type to handle limited-withed
4164 (Attribute_Tag): Check class-wide type interfaces using
4165 the underlying type to handle limited-withed types.
4167 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4169 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4170 over a subtype of a type with a static predicate, taking into
4171 account the predicate function of the parent type and the bounds
4172 given in the loop specification.
4173 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4174 a loop specification that is a subtype indication whose type mark
4175 is a type with a static predicate, inherit predicate function,
4176 used to build case statement for rewritten loop.
4178 2017-09-08 Justin Squirek <squirek@adacore.com>
4180 * lib-load.adb: Modify printing of error message to exclude file
4183 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4185 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4186 don't inline subprograms declared in both visible and private
4188 (In_Package_Spec): previously In_Package_Visible_Spec; now
4189 detects subprograms declared both in visible and private parts
4192 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4194 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4195 the type is an anonymous array in an object declaration, whose
4196 component type has an invariant, use the object declaration
4197 as the insertion point for the invariant procedure, given that
4198 there is no explicit type declaration for an anonymous array type.
4200 2017-09-08 Bob Duff <duff@adacore.com>
4202 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
4204 2017-09-08 Bob Duff <duff@adacore.com>
4206 * a-strfix.adb (Trim): Compute Low and High only if needed.
4208 2017-09-08 Justin Squirek <squirek@adacore.com>
4210 * lib-load.adb (Load_Main_Source): Add error output in the case a
4211 source file is missing.
4213 2017-09-08 Bob Duff <duff@adacore.com>
4216 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4217 Default_WCEM by default (i.e. if the encoding is not specified
4218 by the Form string).
4220 2017-09-08 Bob Duff <duff@adacore.com>
4222 * s-trasym.ads (Hexa_Traceback): If
4223 Suppress_Hex is True, print "..." instead of a hexadecimal
4225 * s-trasym.adb: Ignore No_Hex in this version.
4228 2017-09-08 Bob Duff <duff@adacore.com>
4230 * debug.adb: Minor reformatting.
4232 2017-09-08 Bob Duff <duff@adacore.com>
4234 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4235 code so it doesn't trigger an "uninit var" warning.
4237 2017-09-08 Nicolas Roche <roche@adacore.com>
4239 * s-hibaen.ads: Remove obsolete file.
4241 2017-09-08 Arnaud Charlet <charlet@adacore.com>

4258 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4260 * debug.adb (dA): Adjust comment.
4261 * gnat1drv.adb (Gnat1drv): Likewise.
4262 * opt.ads (List_Representation_Info_Extended): New variable.
4263 * repinfo.adb (List_Record_Info): Split implementation into...
4264 (Compute_Max_Length): ...this. Recurse on records if requested.
4265 (List_Record_Layout): Likewise.
4266 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4267 statement, accept '0' and set List_Representation_Info_Extended
4269 * usage.adb (Usage): Document new -gnatRe variant.
4271 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4273 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4274 Do not save the given entity in the global variable Default_Pool
4275 if the pragma appears within a generic unit.
4277 2017-09-08 Bob Duff <duff@adacore.com>
4279 * errout.adb (Delete_Warning): Do not
4280 decrement Warnings_Treated_As_Errors. This is called before
4281 Warnings_Treated_As_Errors has been incremented to account for
4282 this warning. Decrementing it here can lead to negative values
4283 of Warnings_Treated_As_Errors, raising Constraint_Error in
4284 checks-on builds, and causing the compiler to return an error
4285 code in checks-off builds.
4287 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4289 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4290 entities of named concurrent types as Ref_Id and not of anonymous
4291 concurrent objects (because callers already know when a conversion
4292 is necessary and can easily do it); also, do not expect protected
4293 types or protected objects as Context_Id (because no flow-related
4294 SPARK pragmas are attached there); reflect these changes in a
4295 more precise comment.
4297 2017-09-08 Olivier Hainque <hainque@adacore.com>
4299 * g-altive.ads: Add documentation.
4301 2017-09-08 Bob Duff <duff@adacore.com>
4303 * sem_util.ads, debug.adb: Minor comment fix.
4304 * erroutc.ads: Comment fix.
4306 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4308 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4309 for compatibility of component types of formal and actual in an
4310 instantiation of a child unit, when the component type of the
4311 formal is itself a formal of an enclosing generic.
4313 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4315 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4316 sem_prag.adb to make it available for GNATprove; for concurrent
4317 types replace custom scope climbing with Scope_Same_Or_Within; for
4318 single concurrent objects add scope climbing (with Scope_Within),
4319 which was not there (that's the primary semantic change of this
4320 commit); also, when comparing a single concurrent object with
4321 its corresponding concurrent type rely on equality of types,
4322 not of objects (because that's simpler to code).
4323 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4324 (Analyze_Global_Item): adjust special-casing of references to the
4325 current instance of a concurrent unit in the Global contracts
4326 of task types and single tasks objects; similar for references
4327 in the protected operations and entries of protected types and
4328 single protected objects (in all these cases the current instance
4329 behaves as an implicit parameter and must not be mentioned in
4330 the Global contract).
4332 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4334 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4335 function calls returning a record within a subprogram call,
4338 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4340 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4341 name that designates the current instance of a child unit in its
4342 own body and appears as the prefix of a reference to an entity
4343 local to the child unit.
4344 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4347 2017-09-08 Yannick Moy <moy@adacore.com>

4354 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4355 warnings on internal units in configurable run time mode.
4357 2017-09-08 Bob Duff <duff@adacore.com>
4359 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4360 representation items from interfaces that the derived type
4361 implements, not just from the parent type.
4362 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4363 this to return an empty list when there are no interfaces.
4364 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4365 * sem_attr.adb: Minor comment fix.
4367 2017-09-08 Doug Rupp <rupp@adacore.com>
4369 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
4372 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4374 * exp_ch4.adb (Expand_N_Allocator): Generate a
4375 call to Allocate_Any_Controlled when the allocation does not
4376 require any initialization.
4378 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4380 * sem_util.adb (Copy_Node_With_Replacement):
4381 Update the Renamed_Object field of a replicated object renaming
4384 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4386 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4387 conversions and components of objects. Simplified the detection
4388 of the Count attribute by identifying the corresponding run-time
4391 2017-09-08 Yannick Moy <moy@adacore.com>
4393 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4394 sem_type.adb, sinfo.ads: Minor reformatting.
4396 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4398 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4399 of Freeze_Profile, used to inhibit the freezing of the profile
4400 of an expression function declared within a nested package, when
4401 some type in the profile depends on a private type declared in
4402 an enclosing package.
4404 2017-09-08 Bob Duff <duff@adacore.com>
4406 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4407 the subunit case. It's still OK to set it in the "missing subunits"
4408 case, because that won't cause the obsolete .ali files that cause
4411 2017-09-08 Bob Duff <duff@adacore.com>
4413 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4414 unclear why this didn't cause a warning.
4415 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4416 pragmas. It's unclear why this didn't cause an error.

4453 the placement of a primitive operation O that renames an operation
4454 R declared in an inner package, and which is thus not a primitive

4755 but for all kinds of items.
4756 (Collect_Subprogram_Inputs_Outputs): Do not process formal

4891 Elab_Old and use the order chosen by Elab_Old, possibly with
4892 debugging printouts comparing the two orders." Now it means
4893 "do not run Elab_New." This is of use if there are bugs that

4938 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4940 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4941 entity of a mutable type and the right-hand side is a conditional
4942 expression, resolve the alternatives of the conditional using
4943 the base type of the target entity, because the alternatives
4944 may have distinct subtypes. This is particularly relevant if
4945 the alternatives are aggregates.
4947 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4949 * checks.adb (Apply_Predicate_Check): If the expression is an
4950 aggregate that is the RHS of an assignment, apply the check to
4951 the LHS after the assignment, rather than to the aggregate. This
4952 is more efficient than creating a temporary for the aggregate,
4953 and prevents back-end crashes when the aggregate includes a
4954 dynamic "others' association.
4956 2017-09-06 Yannick Moy <moy@adacore.com>
4958 * sem_ch12.adb (Analyze_Instance_And_Renamings):
4959 Set variable to ignore SPARK_Mode in instance before the analysis
4960 of the generated package declaration.
4962 2017-09-06 Yannick Moy <moy@adacore.com>
4964 * sem_res.adb (Resolve_Call): Do not issue a
4965 message for calls inside expression function, unless body was
4966 seen and is candidate for inlining.
4968 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4970 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
4971 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
4972 body. do not freeze the formals of the generic unit.
4974 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4976 * errout.adb (Error_Msg): Separate the
4977 treatment for warning vs. style messages in inlinings and
4978 instantiations. Prevents blowups on calls to Warn_Insertion for
4979 style messages, which should not be called in that case because
4980 Warning_Msg_Char is not set.
4982 2017-09-06 Justin Squirek <squirek@adacore.com>
4984 * sem_prag.adb (Check_VFA_Conflicts): Created
4985 to group all Volatile_Full_Access checks relating to other
4986 representation pragmas (Mark_Component_Or_Object): Created
4987 to centeralize the flagging of attributes for the record type
4988 component case, a pragma applied individually to a component, and
4990 (Process_Atomic_Independent_Shared_Volatile):
4991 Add propagation of certain pragmas to record components and move
4992 evaluation of VFA checks
4994 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4996 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
4997 Do not warn on conditions that are not obeyed for Inline_Always
4998 subprograms, when assertions are not enabled.
5000 2017-09-06 Arnaud Charlet <charlet@adacore.com>
5002 * sem_util.adb (Unique_Entity): For abstract states return their
5005 2017-09-06 Bob Duff <duff@adacore.com>
5007 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5008 that is a proper body corresponding to a stub, we defer the
5009 adjustment of the sloc until after the correct adjustment has
5010 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5011 the adjustment, because it will be outside the range in (the old,
5012 incorrect) S_Adjustment.
5013 * inline.adb: Use named notation for readability and uniformity.
5014 * sinput-l.adb: Minor improvements to debugging output printed
5016 * sinput-l.ads (Create_Instantiation_Source): Minor comment
5019 2017-09-06 Vincent Celier <celier@adacore.com>
5021 * make.adb: Do not invoke gprbuild for -bargs -P.
5023 2017-09-06 Sylvain Dailler <dailler@adacore.com>
5025 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
5026 case when Op is of kind N_Qualified_Expression. In this case,
5027 the function is called recursively on the subexpression like in
5029 * make.adb: Minor reformatting
5031 2017-09-06 Justin Squirek <squirek@adacore.com>
5033 * einfo.adb (Set_Linker_Section_Pragma): Modify
5034 Set_Linker_Section_Pragma to be consistant with the "getter"
5035 Linker_Section_Pragma.
5036 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5037 checking for container loops so that the index cursor is not
5038 directly changable by the user with the use of E_Loop_Parameter.
5039 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
5040 * sem_warn.adb (Check_References): Revert previous change.
5042 2017-09-06 Bob Duff <duff@adacore.com>

5050 declarations to only consider valid uses of Global/Depends those on
5051 single concurrent objects.

5073 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
5074 gnatname.adb: Remove the Project Manager from the GNAT tools.
5075 * gcc-interface/Makefile.in: ditto.
5077 2017-09-06 Bob Duff <duff@adacore.com>
5079 * sem_util.ads: Minor comment fix.
5081 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5083 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5084 Generate a freeze node for the actual of a formal package, if
5085 the actual is declared in the same unit and has a corresponding
5086 body, to prevent the current instance from being frozen before
5089 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5091 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.
5093 2017-09-06 Yannick Moy <moy@adacore.com>

5111 missing case of controlled generalized indexing.
5112 (Is_Source_Object): Use routine Strip to remove indirections.
5113 (Strip): New routine.
5115 2017-09-06 Bob Duff <duff@adacore.com>
5117 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5118 we include the proper header. Otherwise, we just declare the necessary
5119 things from the capabilities library. This is so we can build on
5120 machines without that library, while still enabling that library.
5121 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5122 simply return 0 if the library is not present, or not included
5125 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5127 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

5138 has no parameter specification and no entry index, use the entry name
5139 as the end of the generated SCO statement.
5141 2017-09-06 Steve Baird <baird@adacore.com>
5143 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5144 uses of 'Image and related attributes as having side effects in
5145 order to avoid replicating such uses.
5146 * pprint.ads (Expression_Image) Add new generic formal flag
5147 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5148 (eventually) override the default.
5149 * pprint.adb (Expression_Image) If the new flag is set, then
5150 suppress the ".all" suffix when displaying a dereference whose
5151 prefix is a use of a value-capturing compiler temp of the sort
5152 generated by Expr_Util.Remove_Side_Effects .
5153 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

5168 so that applies to any entity.
5170 2017-09-06 Yannick Moy <moy@adacore.com>
5172 * sem_ch3.adb (Derived_Type_Declaration): Use
5173 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5175 2017-09-06 Javier Miranda <miranda@adacore.com>
5177 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5180 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5182 * sem_dim.adb (Analyze_Dimension): In an instance, a type

5185 (Dimensions_Of_Operand): Ditto.
5187 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5189 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
5190 null procedures when GNAT coverage is used, so that their (empty)
5191 bodies are properly covered.

5201 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
5202 Universal_Real and the context is a floating-point type, resolve

5210 2017-09-06 Yannick Moy <moy@adacore.com>
5212 * freeze.adb (Check_Inherited_Conditions): Rewriting
5213 of inherited preconditions and postconditions should only occur
5214 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5215 be confused with SPARK_Mode being On.
5217 2017-09-06 Yannick Moy <moy@adacore.com>

5231 * sem_ch7.adb: Add with clause for GNAT.HTable.
5232 (Entity_Table_Size): New constant.
5233 (Entity_Hash): New function.
5234 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5235 (Is_Subprogram_Ref): Rename into...
5236 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5237 the table instead of bailing out on them. Scan the value of constants
5238 if it is not known at compile time.
5239 (Contains_Subprograms_Refs): Rename into...
5240 (Scan_Subprogram_Refs): ...this.
5241 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5242 Is_Public flag on subprograms if they are not actually referenced.
5243 (Hide_Public_Entities): Beef up comment on the algorithm.
5244 Reset the table of subprograms on entry.
5246 2017-09-06 Yannick Moy <moy@adacore.com>

5300 2017-09-06 Bob Duff <duff@adacore.com>
5302 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
5303 check back to the body, because SPARK is not yet ready for

5331 * sem_type.adb (Interface_Present_In_Ancestor): Within an
5332 expression function, or within a spec expression (default value,
5333 etc) a reference to an incomplete type is legal: legality of

5351 we can use modern Ada in this package.
5352 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
5353 Move Ada.Command_Line.Response_File to System.Response_File,
5354 and make Ada.Command_Line.Response_File into a rename of
5355 System.Response_File. This is to avoid having gnatbind depend
5356 Ada.Command_Line, which would damage the bootstrap process now
5357 that Ada.Command_Line contains modern Ada (the raise expression).
5358 * gnatbind.adb: Avoid dependence on
5359 Ada.Command_Line. Depend on System.Response_File instead
5360 of Ada.Command_Line.Response_File. Change one call to
5361 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5362 to Ada.Command_Line.Argument_Count to use Arg_Count.
5363 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5365 2017-09-06 Bob Duff <duff@adacore.com>

5373 "Assert(False)" with "return Iter", because if an iterable

5375 overriding or inherited default iterator.
5377 2017-09-06 Yannick Moy <moy@adacore.com>
5379 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

5388 (Write_Field15_Name): Update the output for
5389 Status_Flag_Or_Transient_Decl.
5390 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
5391 to loop parameters. Update the documentation of the attribute
5392 and the E_Loop_Parameter entity.
5393 * exp_ch7.adb (Process_Declarations): Remove the bogus guard
5394 which assumes that cursors can never be controlled.
5395 * exp_util.adb (Requires_Cleanup_Actions): Remove the bogus
5396 guard which assumes that cursors can never be controlled.

5407 are not elementary types.
5409 2017-09-06 Justin Squirek <squirek@adacore.com>
5411 * sem_attr.adb: Comment correction.
5413 2017-09-06 Gary Dismukes <dismukes@adacore.com>

5427 * sem_ch6.adb (Check_Returns): Clean up warnings coming from
5428 generated bodies for renamings that are completions, when renamed
5429 procedure is No_Return.
5430 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality

5502 not retrievable as selected components.
5504 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5506 * sem_util.adb (Needs_One_Formal): The first formal of such a

5545 constraint for it, given that the constrained discriminants are
5546 not visible in the object.
5547 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5548 side may be derived from that of the left-hand side (as in the
5549 case of an assignment with a change of representation) so the
5550 discriminant to be used in the retrieval of the value of the
5551 component must be the entity in the type of the right-hand side.

6126 * exp_ch6.adb (Expand_Call_Helper): When locating the
6127 accessibility entity created for an access parameter, handle
6128 properly a reference to a formal of an enclosing subprogram. if
6129 the reference appears in an inherited class-wide condition, it
6130 is the rewriting of the reference in the ancestor expression,
6131 but the accessibility entity must be that of the current formal.
6133 2017-05-02 Javier Miranda <miranda@adacore.com>
6135 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6170 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6171 procedure body for a local (sub)type declaration within a
6172 predicate function. Invariant checks do not apply to these, and
6173 the expansion of the procedure will happen in the wrong scope,
6174 leading to misplaced freeze nodes.
6176 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6178 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6179 to analyze generated actions. If the main unit is a body,

6184 * einfo.adb (Declaration_Node): flip branches of
6185 an IF statement to avoid repeated negations in its condition;

6215 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6216 Refine predicate for the case where the primitive operation
6217 is a renaming of equality. An overriding operation that is
6218 a user-defined renaming of predefined equality inherits its
6219 slot from the overridden operation. Otherwise it is treated
6220 as a predefined op and occupies the same predefined slot as
6221 equality. A call to it is transformed into a call to its alias,
6222 which is the predefined equality. A dispatching call thus uses
6223 the proper slot if operation is further inherited and called
6224 with class-wide arguments.
6226 2017-05-02 Justin Squirek <squirek@adacore.com>
6228 * errout.adb (Set_Msg_Text): Add a case to switch the message

6232 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6233 to handle new warning mode

6237 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6239 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6240 declaration that operates on some fixed point type.

6257 condition and then-expression.
6259 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6261 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6262 statement if the initialization call is a null procedure, as
6263 can happen with a controlled type with no explicit Initialize
6264 procedure, or an array of such.
6265 * exp_ch7.adb (Process_Object_Declaration): For a type with
6266 controlled components that has a trivial Initialize procedure,
6267 insert declaration for finalization counter after object

6270 finalization block and attendant declarations if component has
6271 a trivial Initialize procedure.
6272 (Make_Init_Call): Do not generate a call if controlled type has
6273 a trivial Initialize procedure.

6303 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6305 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6306 parameter Array_Comp to indicate the case of an array object
6307 with null-excluding components.
6308 * checks.adb (Null_Exclusion_Static_Checks):
6309 Call Compile_Time_Constraint_Error instead of
6310 Apply_Compile_Time_Constraint_Error in the component case. Also
6311 call that when Array_Comp is True, with an appropriate warning for
6312 the array component case. Only create an explicit initialization
6313 by null in the case of an object of a null-excluding access type
6314 (and no longer do that in the component case).
6315 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6316 Array_Comp defaulted to False. Pass Empty for the Comp
6317 actual when calling Null_Exclusion_Static_Checks in the case
6318 where Comp_Decl matches Object_Decl, because we don't have a
6319 component in that case. In the case of an object or component
6320 of an array type, pass True for Array_Comp on the recursive call

6325 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6326 compute the linux priority from the Ada priority. Call this everywhere
6327 required. In particular, the previous version was not doing this
6328 computation when setting the ceiling priority in various places. It
6329 was just converting to C.int, which results in a ceiling that is off
6332 2017-05-02 Ed Schonberg <schonberg@adacore.com>

6351 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6352 here from exp_ch9, to recognize objects whose creation requires
6353 dynamic allocation, so that the proper warning can be emitted
6354 when restriction No_Implicit_Heap_Allocation is in effect.
6355 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6356 to emit proper warning when an object that requires dynamic

6423 function to expand operator /=.
6425 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6427 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6428 Simplify the expression for a fixed-fixed division to remove
6429 divisions by constants whenever possible, as an optimization
6430 for restricted targets.

6434 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6436 2017-05-02 Bob Duff <duff@adacore.com>
6438 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6439 to find primitive ops, instead of using an Identifier that will
6440 later be looked up. This is necessary because these ops are not
6441 necessarily visible at all places where we need to call them.
6442 * exp_util.ads: Minor comment fix.
6444 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6446 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6447 references are fully conformant if they are both expansions
6448 of the discriminant of a protected type, within one of the
6449 protected operations. One occurrence may be expanded into a
6450 constant declaration while the other is an input parameter to
6451 the corresponding generated subprogram.

6455 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6456 recursivly searching composite-types for null-excluding access
6457 types and verifying them.
6458 (Analyze_Object_Declaration): Add a
6459 call to Check_Null_Excluding_Components for static verification
6460 of non-initialized objects.
6461 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6462 a parameter for a composite-type's component and an extra case
6463 for printing component information.

6481 array components specially.
6483 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6485 * sem_ch8.adb (Premature_Usage): If the premature usage of
6486 an entity is as the expression in its own object decaration,
6487 rewrite the reference as Any_Id to prevent cascaded errors or
6488 compiler loops when such an entity is used in an address clause.
6490 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6492 * gcc-interface/decl.c (components_to_record): Add missing guard.

6497 Put back pending fields onto the regular list if the misalignment
6498 happens to cancel itself.
6500 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6502 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6503 controlling actual in a prefixed call, preserve the original node
6504 information if the prefix itself has been rewritten, for ASIS use.
6506 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6508 * exp_ch6.adb (Insert_Post_Call_Actions):
6509 Code clean up. Insert the post-call actions after an enclosing
6510 procedure call when N denotes a function call and appears as an
6511 actual parameter in the procedure call.
6513 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6515 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6516 for the component, also reject the attribute if the component
6517 doesn't end on a byte boundary and its scalar storage order is
6518 different from that of the enclosing record type.
6520 2017-04-28 Javier Miranda <miranda@adacore.com>
6522 * atree.ads (Info_Messages): Removed.

6552 2017-04-28 Bob Duff <duff@adacore.com>
6554 * sem_util.ads, sem_util.adb (Might_Raise): New function
6555 that replaces Is_Exception_Safe, but has the opposite
6556 sense. Is_Exception_Safe was missing various cases -- calls inside
6557 a pragma Debug, calls inside an 'if' or assignment statement,
6558 etc. Might_Raise now walks the entire subtree looking for things
6560 * exp_ch9.adb (Is_Exception_Safe): Remove.
6561 (Build_Protected_Subprogram_Body): Replace call to
6562 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6563 constants where possible).
6564 * exp_ch7.adb: Rename Is_Protected_Body -->
6565 Is_Protected_Subp_Body. A protected_body is something different

6594 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6595 Interrupt_Handler and Attach_Handler): Generate reference
6596 to protected operation to prevent spurious warnings about
6597 unreferenced entities. Previous scheme failed with style checks
6600 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6602 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6603 that follows an expression function must not be relocated to
6604 the generated body, because it applies to the code that follows.
6606 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6608 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6609 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6610 code that might violate the more stringent checking for 'Access
6611 introduced in Ada 2005.
6613 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6615 * a-cforse.adb: minor style fix in comment.
6617 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6619 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6620 initialize Block_Decls variable.
6621 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6622 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

6631 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6633 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6635 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6636 node between access types, freeze the designated type as well,
6637 so that dispatch table pointers are created in the proper scope,
6638 and not in the constructed body of the expression function.
6640 2017-04-28 Bob Duff <duff@adacore.com>
6642 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6643 value makes large compilations faster, but small compilations slower.
6645 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6647 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6649 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6651 * erroutc.adb (Compilation_Errors): Do not consider info messages
6652 as suitable warnings when warnings must be treated as errors.
6653 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6654 internally-generated packages when outputting completion
6656 * errout.adb (Output_Messages): Do not consider info messages as

6659 suitable warnings when warnings must be treated as errors.
6661 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6663 * warnsw.ads: Minor fix for incorrect wording in comment.
6665 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6667 * sem_res.adb (In_Instance_Code): New predicate in
6668 Valid_Conversion, to determine whether a type conversion appears
6669 as (or within) an actual for a formal object. Type conversions
6670 in instances are not rechecked in Valid_Conversion because
6671 visibility changes between generic location andi instance may
6672 lead to spurious errors, but conversions within an actual must be
6673 fully checked, and they are not fully resolved when pre-analyzing
6676 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6678 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6679 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6680 of the relocated node will have mangled Parent pointers.
6681 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6682 tables used in conjunction with entity and itype replication.
6683 (Visit_Entity): Rewrite the restriction on which entities

6718 (Restore_Warnings): Likewise.
6719 (Save_Warnings): Likewise.
6720 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6721 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6722 components_to_record.
6723 (gnu_field_to_gnat): New function.
6724 (warn_on_field_placement): Likewise.
6725 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6726 parameters. Rename local variables and adjust recursive call.
6727 Rework final scan of the field list and implement warnings on the
6728 problematic placement of specific sorts of fields.
6730 2017-04-27 Bob Duff <duff@adacore.com>
6732 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6737 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6738 For efficiency, cache results of Is_Internal_File_Name and
6739 Is_Predefined_File_Name in the Units table. This avoids a lot
6740 of repeated text processing.
6742 2017-04-27 Emmanuel Briot <briot@adacore.com>
6744 * g-comlin.adb (Sort_Sections): remove useless test.
6746 2017-04-27 Claire Dross <dross@adacore.com>
6748 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6749 allow the use of regular equality over elements in contracts.
6750 (Formal_Model): Ghost package containing model functions that are
6751 used in subprogram contracts.
6752 (Current_To_Last): Removed, model functions should be used instead.
6753 (First_To_Previous): Removed, model functions should be used instead.
6754 (Strict_Equal): Removed, model functions should be used instead.
6755 (No_Overlap): Removed, model functions should be used instead.
6756 (Equivalent_Keys): Functions over cursors are removed. They were
6757 awkward with explicit container parameters.
6758 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6759 allow the use of regular equality over elements in contracts.
6760 (Formal_Model): Ghost package containing model functions that

6769 * gnat1drv.adb: Code cleanup.
6771 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6773 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6774 attribute reference in a post- condition is the subprogram to
6775 which the condition applies. If the condition is inherited
6776 by a type extension, the prefix becomes a reference to the
6777 inherited operation, but there is no need to create a wrapper
6778 for this operation, because 'Result is expanded independently
6779 when elaborating the postconditions.
6781 2017-04-27 Bob Duff <duff@adacore.com>
6783 * sinput.adb: Minor code cleanup.
6784 * namet.adb (Append): Create faster versions of
6785 Append(String) and Append(Name_Id) by using slice assignment
6787 * sem_util.adb (In_Instance): Speed this up by removing
6788 unnecessary tests; Is_Generic_Instance is defined for all
6790 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6791 Remove unused function.
6792 * alloc.ads (Nodes_Initial): Use a much larger value, because
6793 the compiler was spending a lot of time copying the nodes table
6794 when it grows. This number was chosen in 1996, so is rather out
6795 of date with current memory sizes. Anyway, it's virtual memory.
6796 Get rid of Orig_Nodes_...; use Node_... instead.
6797 * atree.adb (Lock): Do not release the Nodes tables; it's a
6799 Orig_Nodes_ ==> Nodes_
6800 * nlists.adb: Orig_Nodes_ ==> Nodes_
6801 * g-table.adb: Remove unused "with" clause.
6802 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6803 not be used by clients.
6804 * g-dyntab.adb (Last_Allocated): New function
6805 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
6807 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6809 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
6811 (Subtypes_Statically_Match): Remove duplicate check.

6831 processing for Ada 83 and instances.
6832 (Object_Access_Level): Merge the processing for indexed components
6833 and selected components.
6834 * uname.adb (Add_Node_Name): Merge the processing for stubs.

6845 of Expand_Dispatching_Call. If the denoted subprogram has a
6846 class-wide precondition, this is the only precondition that
6847 applies to the call, rather that the class-wide preconditions
6848 that may apply to the body that is executed. (This is specified
6851 2017-04-27 Yannick Moy <moy@adacore.com>
6853 * gnat1drv.adb (Adjust_Global_Switches): Issue
6854 a warning in GNATprove mode if the runtime library does not
6855 support IEEE-754 floats.
6857 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6859 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6860 is itself inherited it does not carry any contract information,
6861 so examine its parent operation which is its Alias.
6863 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6865 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6866 prefix can be an object reference in which case Obj'Image (X)
6867 can only be interpreted as an indexing of the parameterless
6868 version of the attribute.
6869 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6870 an indexing or a slice operation if the attribute does not require
6871 parameters. In Ada2012 'Image also belongs in this category,
6872 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6874 2017-04-27 Yannick Moy <moy@adacore.com>
6876 * exp_ch4.adb: Minor reformatting.
6877 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
6878 disable the CodePeer and C generation modes. Similar to the
6879 opposite actions done in CodePeer mode.

6901 2017-04-27 Bob Duff <duff@adacore.com>
6903 * g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.
6904 If the table grows and then shrinks back to empty, we won't necessarily

7418 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
7419 in gnat1 and gnatbind.
7420 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
7421 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o
7422 * s-excmac.ads, s-excmac.adb: Copy of variants.

7429 modifications in functional containers.
7430 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7431 to improve readablity. Subprograms are separated between basic
7432 operations, constructors and properties. Universally quantified
7433 formulas in contracts are factorized in independant functions
7434 with a name and a comment. Names of parameters are improved.
7436 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7438 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7440 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7442 * sem_res.adb (Resolve_Type_Conversion): Do not
7443 install a predicate check here since this is already done during
7444 the expansion phase. Verify whether the operand satisfies the
7445 static predicate (if any) of the target type.
7446 * sem_ch3.adb (Analyze_Object_Declaration): Do
7447 not install a predicate check if the object is initialized by
7448 means of a type conversion because the conversion is subjected
7451 2017-04-27 Tristan Gingold <gingold@adacore.com>
7453 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
7454 replaced by their variants).
7456 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

7460 a-cofuma.ads, a-cofuba.adb, a-cofuba.ads: Minor reformatting.
7462 2017-04-27 Tristan Gingold <gingold@adacore.com>
7464 * s-excmac-gcc.ads, s-excmac-gcc.adb,
7465 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
7468 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7470 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7471 the loop which detects potential enclosing transient scopes. The
7472 loop now terminates much earlier as transient scopes are bounded
7473 by packages and subprograms.
7475 2017-04-27 Claire Dross <dross@adacore.com>
7477 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7478 allow the use of regular equality over elements in contracts.
7479 (Cursor): Type is now public so that it can be used in
7481 (Formal_Model): Ghost package containing
7482 model functions that are used in subprogram contracts.
7483 (Current_To_Last): Removed, model functions should be used
7485 (First_To_Previous): Removed, model functions should
7487 (Strict_Equal): Removed, model functions
7488 should be used instead.
7489 (Append): Default parameter value
7490 replaced by new wrapper to allow more precise contracts.
7491 (Insert): Default parameter value replaced by new wrapper to
7492 allow more precise contracts.

7494 value replaced by new wrapper to allow more precise contracts.
7495 (Prepend): Default parameter value replaced by new wrapper to
7496 allow more precise contracts.
7497 (Delete_First): Default parameter
7498 value replaced by new wrapper to allow more precise contracts.
7499 (Delete_Last): Default parameter value replaced by new wrapper

7504 * exp_spark.adb (Expand_SPARK): Perform specialized expansion
7505 for object declarations.
7506 (Expand_SPARK_N_Object_Declaration): New routine.

7508 Default_Initial_Condition procedure of a type under the SPARK
7509 elaboration checks umbrella.
7511 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7513 * sem.adb (Analyze): Diagnose an illegal iterated component
7515 * sem_util.ads, sem_util.adb

7518 2017-04-27 Bob Duff <duff@adacore.com>
7520 * adaint.c (__gnat_get_current_dir): Return 0 in length if
7522 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7523 exception if getcwd failed.
7525 2017-04-27 Yannick Moy <moy@adacore.com>

7528 entities with special prefix.
7530 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7532 * debug.adb Change the documentation of switch -gnatd.s.
7533 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7534 to manage the secondary stack when an enclosing scope already
7535 performs this functionality (aka relaxed management). Switch
7536 -gnatd.s may be used to force strict management in which case
7537 the block will manage the secondary stack unconditionally. Add
7538 a guard to stop the traversal when encountering a package or a
7541 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7543 * sem_res.adb (Resolve_Call): Refine further the handling of
7544 limited views of return types in function calls. If the function
7545 that returns a limited view appears in the current unit,
7546 we do not replace its type by the non-limited view because
7547 this transformation is performed int the back-end. However,
7548 the type of the call itself must be the non-limited view, to
7549 prevent spurious resolution errors.
7551 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7553 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7554 Removed, proposed implementation using generics for class-wide
7555 preconditions proved impractical.
7556 (Class_Wide_Clone): New attribute of subprogram. Designates
7557 subprogram created for primitive operations with class-wide
7558 pre/postconditions that contain calls to other primitives. The
7559 clone holds the body of the original primitive, but the
7560 pre/postonditions do not apply to it. The original body is
7561 rewritten as a wrapper for a call to the clone.
7562 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7563 the flag is set, no code for the corresponding pre/postconditions
7564 is inserted into its body.
7566 2017-04-27 Bob Duff <duff@adacore.com>
7568 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
7569 Scalar_Storage_Order if -gnatI is given.
7570 * sem_prag.adb (Analyze_Pragma): Ignore
7571 Default_Scalar_Storage_Order if -gnatI is given.

7579 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
7580 (Remove): New function that removes an element from a set.
7581 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
7582 (Remove): New function that removes an element from a sequence.
7583 (Insert): New function that adds anywhere in a sequence.

7596 of attribute 'Result is not considered a violation of pragma
7599 2017-04-27 Justin Squirek <squirek@adacore.com>
7601 * cstand.adb (Create_Standard): Correctly set
7602 Directly_Designated_Type for Any_Access.

7612 private child of Ada.Containers used to implement all functional
7614 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7615 child of Ada.Containers. It provides functional indefinite unbounded
7616 maps which can be used as high level models for specification
7618 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7619 child of Ada.Containers. It provides functional indefinite unbounded
7620 sets which can be used as high level models for specification
7622 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7623 child of Ada.Containers. It provides functional indefinite unbounded
7624 vectors which can be used as high level models for specification
7626 * Makefile.rtl: Add new packages.
7627 * impunit.adb: Add new packages.
7629 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7631 * sem_ch4.adb: Minor reformatting.
7633 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7635 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7636 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7637 point type actual that has user-defined arithmetic primitives,
7638 when there is a previous actual for a formal package that defines
7639 a fixed-point type with the parent user-defined operator.
7641 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7643 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7644 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7645 the component type allows range checks.
7647 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7649 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7650 corresponding declaration, because formal derived types are
7651 rewritten as private extensions.
7653 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7655 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7656 dimensions of operands if node has been analyzed already, because
7657 previous analysis and dimension checking will have removed the
7658 dimension information from the operands.
7660 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7662 * debug.adb: Document the use of switch -gnatd.s.
7663 * einfo.ads Update the documentation on attribute
7664 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7665 the uses of these attributes from certain entities.
7666 * exp_ch7.adb (Make_Transient_Block): Reimplement the circuitry
7667 which determines whether the block should continue to manage
7668 the secondary stack.

7722 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7723 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7724 Ada_2012 instead of Ada_2005 to be compatible with the above
7726 * bindgen.adb: Silence new warning on pragma Ada_95.
7728 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7741 Fix spelling mistakes.
7743 2017-04-25 Bob Duff <duff@adacore.com>
7745 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7746 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7747 for source buffers. Fix misc obscure bugs.
7748 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7749 checking, for source buffers. Modify representation clause for
7750 Source_File_Record as appropriate. Move Source_File_Index_Table
7751 from spec to body, because it is not used outside the body.
7752 Move Set_Source_File_Index_Table into the private part, because
7753 it is used only in the body and in children. Use trickery to
7754 modify the dope in the generic instantiation case. It's ugly,
7755 but not as ugly as the previous method. Fix documentation.
7756 Remove obsolete code.

7772 expander is not active or when index/range checks are suppressed
7774 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7775 Remove variants that include a Supress parameter. These routines
7776 are never used, and were introduced before the current scope-based
7777 check suppression method.
7779 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

7807 error on the return type of an expression function that is a
7808 completion, if the type is derived from a generic formal type.
7810 2017-04-25 Ed Schonberg <schonberg@adacore.com>

7828 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7829 the Internal_Source buffer. This removes the incorrect call to "="
7830 the customer noticed.
7831 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7832 eventually need to eliminate them altogether. Or else get rid
7833 of zero-origin addressing.

8117 further expansion for the unchecked union.
8118 (Expand_Attribute_Reference, case 'Write): If the type is
8119 an unchecked_union, check whether enclosing scope is a Write
8120 subprogram. Replace attribute with a Raise_Program_Error if the
8121 discriminants of the unchecked_union type have not default values
8122 because such a use is erroneous..

8209 When resolving against any fixed type, set the type of the
8210 operand as universal real when the operand is a multiplication
8211 or a division where both operands are of any fixed type.
8212 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the
8213 placement of an error message by pointing to the operand of a
8214 type conversion rather than the conversion itself.
8216 2017-04-25 Thomas Quinot <quinot@adacore.com>

8284 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
8285 overlap if the two formals have different types, because formally
8286 the corresponding actuals cannot designate the same objects.
8288 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8290 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
8291 dimensions are present from context, use them. b) If operand is
8292 a static constant rewritten as a literal, obtain the dimensions

8321 2017-04-25 Justin Squirek <squirek@adacore.com>
8323 * exp_ch3.adb (Freeze_Type): Add condition to always treat
8324 interface types as a partial view of a private type for the
8325 generation of invariant procedure bodies.
8326 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
8327 Add a condition to get the Corresponding_Record_Type for

8331 (Add_Interface_Invariatns),
8332 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
8333 to including the working type T.
8334 (Add_Own_Invariants): Remove
8335 legacy condition for separate units, remove dispatching for ASIS
8336 and save a copy of the expression in the pragma expression.
8337 (Build_Invariant_Procedure_Body): Default initalize vars,
8338 remove return condition on interfaces, always use the
8339 private type for interfaces, and move the processing of types
8340 until after the processing of invariants for the full view.
8341 (Build_Invariant_Procedure_Declaration): Remove condition
8342 to return if an interface type is encountered and add
8343 condition to convert the formal parameter to its class-wide
8344 counterpart if Work_Typ is abstract.
8345 (Replace_Type): Add call to Remove_Controlling_Arguments.
8346 (Replace_Type_Ref): Remove class-wide dispatching for the current
8347 instance of the type.

8352 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
8353 to the change made to Freeze_Type in exp_ch3. Add a condition
8354 to treat interface types as a partial view.
8355 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
8356 to Build_Invariant_Procedure_Declaration to properly generate a
8357 "partial" invariant procedure when Typ is an interface.

8361 * a-numeri.ads: Go back to using brackets encoding for the Greek
8364 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8366 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8367 (10-15): if derived type T with progenitors is abstract,
8368 and primitive P of this type inherits non-trivial classwide
8369 preconditions from both a parent operation and from an interface
8370 operation, then the inherited operation is abstract if the parent
8371 operation is not null.
8372 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8373 with Covered_Interface_Op to yield the actual interface operation
8374 that is implemented by a given inherited operation.

8401 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8402 dereference is introduced for the object, and the object is
8403 overloaded, do not check whether it is aliased, because it may
8404 include an implicit dereference.
8405 * sem_type.adb (Disambiguate): If two interpretations are access
8406 attribute types with the same designated type keep either of
8407 them and do not report an ambiguity. A true ambiguity will be
8410 2017-04-25 Bob Duff <duff@adacore.com>
8412 * a-numeri.ads: Change the encoding of Greek letter Pi from
8413 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8414 to indicate the encoding. We considered using a byte order mark
8415 (BOM), but that causes various trouble (misc software eats the
8416 BOM, if you have a patch with a BOM, then it's not at the start
8417 of the patch, so it's not a BOM, the BOM affects with-ing files,

8461 enforce legality rule on classwide preconditions inherited from
8462 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8463 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8464 subprogram need not be dispatching if it appears in a precondition
8465 for an abstract or null subprogram.
8467 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8469 * sem_ch10.adb: Minor typo fix.

8478 have a length which is a power of 2.
8479 (Is_Predefined_File_Name): Likewise. Adjust comment.
8481 2017-04-25 Bob Duff <duff@adacore.com>
8483 * exp_aggr.adb (Component_Count): Protect the
8484 arithmetic from attempting to convert a value >= 2**31 to Int,
8485 which would otherwise raise Constraint_Error.
8487 2017-04-25 Bob Duff <duff@adacore.com>
8489 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8490 first character of the policy name is not unique.

8513 Save and restore the value of global flag
8514 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

8516 the corresponding spec or the body must ignore all SPARK_Mode
8517 pragmas found within.
8518 (Analyze_Subprogram_Declaration): Mark
8519 the spec when it needs to ignore all SPARK_Mode pragmas found
8520 within to allow the body to infer this property in case it is
8521 instantiated or inlined later.
8522 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8523 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8524 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8525 when the corresponding spec also ignored all SPARK_Mode pragmas
8527 (Analyze_Package_Declaration): Mark the spec when
8528 it needs to ignore all SPARK_Mode pragmas found within to allow

8532 Save and restore the value of flag
8533 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8534 formal spec when it needs to ignore all SPARK_Mode

8536 property in case it is instantiated or inlined later.
8537 (Analyze_Package_Instantiation): Save and restore the value
8538 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8539 the instance spec when it needs to ignore all SPARK_Mode

8583 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8584 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8585 variable and set it to True whenever the main hash table is
8586 populated. Short- circuit the Assoc function if it is false
8587 and add associated guards.
8589 2017-04-25 Olivier Hainque <hainque@adacore.com>
8591 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8592 specs without elaboration code that have an elaboration counter
8593 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8594 * sem_ch10.adb (Analyze_Compilation_Unit):
8595 Set_Elaboration_Entity_Required when requested to preserve
8596 control flow, to ensure the unit elaboration is materialized at
8597 bind time, resulting in the inclusion of the unit object file
8598 in the executable closure at link time.
8600 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8602 * exp_dbug.adb: In Debug_Renaming_Declaration,
8603 when dealing with indexed component, accept to produce a renaming
8604 symbol when the index is an IN parameter or when it is a name
8605 defined in an outer scope.
8607 2017-04-25 Yannick Moy <moy@adacore.com>
8609 * errout.adb (Error_Msg): Adapt continuation
8610 message in instantiations and inlined bodies for info messages.
8612 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8614 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8615 Use direct 4-character slice comparisons.
8617 pragma Inline. (Has_Suffix): Delete.
8618 (Is_Internal_File_Name):
8619 Test Is_Predefined_File_Name first.
8620 (Is_Predefined_File_Name):

8624 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8626 * checks.adb (Insert_Valid_Check): Code cleanup.
8627 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8628 (Expand_Actuals): Generate proper copy-back for a validation
8629 variable when it acts as the argument of a type conversion.
8630 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8631 predicate to operate on type qualifications.
8633 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8635 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8638 2017-04-25 Bob Duff <duff@adacore.com>
8640 * sem_prag.adb (No_Return): Give an error if the pragma applies
8641 to a body. Specialize the error for the specless body case,
8642 as is done for (e.g.) pragma Convention.
8643 * debug.adb: Add switch -gnatd.J to disable the above legality
8644 checks. This is mainly for use in our test suite, to avoid
8645 rewriting a lot of illegal (but working) code. It might also
8646 be useful to customers. Under this switch, if a pragma No_Return
8647 applies to a body, and the procedure raises an exception (as it
8648 should), the pragma has no effect. If the procedure does return,
8649 execution is erroneous.
8651 2017-04-25 Bob Duff <duff@adacore.com>
8653 * exp_ch6.adb (Expand_Actuals): This is the
8654 root of the problem. It took N as an 'in out' parameter, and in
8655 some cases, rewrote N, but then set N to Original_Node(N). So
8656 the node returned in N had no Parent. The caller continued
8657 processing of this orphaned node. In some cases that caused a
8658 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8659 and trips over the Empty Parent). The solution is to make N an
8660 'in' parameter. Instead of rewriting it, return the list of
8661 post-call actions, so the caller can do the rewriting later,
8662 after N has been fully processed.
8663 (Expand_Call_Helper): Move most of Expand_Call here. It has
8664 too many premature 'return' statements, and we want to do the
8665 rewriting on return.
8666 (Insert_Post_Call_Actions): New procedure to insert the post-call
8667 actions in the appropriate place. In the problematic case,
8668 that involves rewriting N as an Expression_With_Actions.
8669 (Expand_Call): Call the new procedures Expand_Call_Helper and
8670 Insert_Post_Call_Actions.
8672 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8674 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8675 properly type derived from generic formal types, to handle
8676 properly modified version of ACATS 4.1B B611017.
8678 2017-04-25 Javier Miranda <miranda@adacore.com>
8680 * exp_unst.adb (Subp_Index): Adding missing
8681 support for renamings and functions that return a constrained
8682 array type (i.e. functions for which the frontend built a
8683 procedure with an extra out parameter).
8685 2017-04-25 Pascal Obry <obry@adacore.com>
8687 * s-string.adb: Minor code clean-up.
8689 2017-04-25 Bob Duff <duff@adacore.com>

8696 2017-04-25 Bob Duff <duff@adacore.com>
8698 * prep.adb (Preprocess): Remove incorrect
8699 Assert. Current character can be ASCII.CR.
8701 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8703 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8704 convention Stdcall, which has a number of exceptions. Convention
8705 is legal on a component declaration whose type is an anonymous
8706 access to subprogram.
8708 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8710 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8711 (Try_One_Prefix_Interpretation): Use the base type when dealing
8712 with a subtype created for purposes of constraining a private
8713 type with discriminants.
8715 2017-04-25 Javier Miranda <miranda@adacore.com>
8717 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

8719 dispatching primitives (Restore_Warnings): Restore warning on
8720 late dispatching primitives (Save_Warnings): Save warning on late
8721 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8722 to enable/disable this warning.
8723 (WA_Warnings): Set warning on late dispatching primitives.
8724 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8725 that its parent type has a private extension.
8726 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8728 * usage.adb: Document -gnatw.j and -gnatw.J.
8730 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8732 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8735 2017-04-25 Bob Duff <duff@adacore.com>
8737 * binde.adb (Validate): Do not pass dynamic strings
8738 to pragma Assert, because older compilers do not support that.
8740 2017-04-25 Bob Duff <duff@adacore.com>
8742 * s-fileio.adb (Close): When a temp file is
8743 closed, delete it and clean up its Temp_File_Record immediately,
8744 rather than waiting until later.
8745 (Temp_File_Record): Add File
8746 component, so Close can know which Temp_File_Record corresponds
8747 to the file being closed.
8748 (Delete): Don't delete temp files,
8749 because they are deleted by Close.
8750 (Open): Set the File component
8751 of Temp_File_Record. This requires moving the creation of the
8752 Temp_File_Record to the end, after the AFCB has been created.
8754 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8756 * checks.adb (Insert_Valid_Check): Do not generate
8757 a validity check when inside a generic.
8759 2017-04-25 Yannick Moy <moy@adacore.com>
8761 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.

8771 concerning inheritance of class-wide preconditions do not apply
8774 2017-04-25 Bob Duff <duff@adacore.com>
8776 * s-ficobl.ads: Minor comment fix.
8778 2017-04-25 Yannick Moy <moy@adacore.com>
8780 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8781 conversions from float to integer in GNATprove mode.
8782 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8783 to call Apply_Type_Conversion_Checks, so that range checks
8784 are properly positioned when needed on conversions, including
8785 when converting from float to integer. (Determine_Range): In
8786 GNATprove mode, take into account the possibility of conversion
8787 from float to integer.
8788 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8789 check on conversions from fixed-point to integer, not anymore
8790 on conversions from floating-point to integer, when in GNATprove
8793 2017-04-25 Yannick Moy <moy@adacore.com>
8795 * checks.adb (Determine_Range_R): Special case type conversions
8796 from integer to float in order to get bounds in that case too.
8797 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8798 mode, for computations involved in interval checking.

8812 * exp_attr.adb (Make_Range_Test): Add processing for validation
8813 variables to avoid extra reads and copies of the prefix.
8814 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8815 variables in order to reflect any changes done in the variable
8816 back into the original object.
8817 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8818 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8826 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8828 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8829 Analyze_Pre_Post_Condition, to implement the legality checks
8830 mandated by AI12-0131: Pre'Class shall not be specified for an
8831 overriding primitive subprogram of a tagged type T unless the
8832 Pre'Class aspect is specified for the corresponding primitive
8833 subprogram of some ancestor of T.
8835 2017-04-25 Bob Duff <duff@adacore.com>
8837 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8838 is redundant, set its Used_Operations to empty. This is only
8839 necessary for use clauses that appear in the parent of a generic
8840 child unit, because those use clauses get reanalyzed when we
8841 instantiate the generic, and we don't want the Used_Operations
8842 carried over from the original context (where it was probably
8845 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8847 * exp_ch6.adb: Minor reformatting.

8855 * par.adb (Par): Null out Current_Source_File, to ensure that
8856 the above bugs won't rear their ugly heads again.
8858 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8860 * sem_ch8.adb (Find_Type): For an attribute reference
8861 'Class, if prefix type is synchronized and previous errors
8862 have suppressed the creation of the corresponding record type,
8863 create a spurious class-wide for the synchonized type itself,
8864 to catch other misuses of the attribute
8866 2017-04-25 Steve Baird <baird@adacore.com>
8868 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode

8872 if CodePeer_Mode is True, then don't generate the
8873 tag checks for the result of call to an instance of
8874 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8875 descendant of" check and the accessibility check).
8877 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8879 * sem_ch13.adb: Code cleanups.
8880 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

8885 * exp_ch4.adb (Library_Level_Target): New function.
8886 (Expand_Concatenate): When optimization is enabled, also expand
8887 the operation out-of-line if the concatenation is present within
8888 the expression of the declaration of a library-level object and
8889 not only if it is the expression of the declaration.
8891 2017-04-25 Bob Duff <duff@adacore.com>
8893 * freeze.adb (Freeze_Object_Declaration): Do
8894 not Remove_Side_Effects if there is a pragma Linker_Section,
8895 because in that case we want static initialization in the
8896 appropriate section.
8898 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8900 * exp_dbug.adb: Minor rewording and reformatting.
8902 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8904 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8905 handle the proposed changes to rules concerning potentially
8906 unevaluated expressions, to include selected components that
8907 do not depend on discriminants, and indexed components with
8909 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8910 predicate in quantified expression, and fix bugs in the handling
8911 of case expressions and membership test.
8912 (Analyze_Attribute_Old_Result): use new predicate.
8913 (Analyze_Attribute, case Loop_Entry): ditto.
8915 2017-04-25 Bob Duff <duff@adacore.com>
8917 * s-secsta.adb (SS_Info): Add a comment
8918 explaining why we don't need to walk all the chunks in order to
8919 compute the total size.
8921 2017-04-25 Bob Duff <duff@adacore.com>

8953 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8954 internal calls that appear in preconditions of protected
8955 operations, in default values for same, and in contract guards
8956 for contract cases in SPARK.

8967 * a-numaux-x86.ads: Fix package description.
8968 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8969 (Reduce): Adjust and complete description. Call Is_Nan instead of
8970 testing manually. Use an integer temporary to hold rounded value.
8971 * a-numaux-darwin.adb (Reduce): Likewise.
8972 (Is_Nan): New function.
8974 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8976 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8977 on analysis of prefix whose type is a current instance of a

8983 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8984 the identity of callable entities therein, because they have been
8985 properly resolved, and prefixed calls may have been rewritten
8988 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8990 * exp_ch3.adb (Build_Init_Statements): Convert
8991 the expression of the pragma/aspect Secondary_Stack_Size to

9004 * s-osinte-freebsd.ads: Minor comment tweaks
9006 2017-04-25 Javier Miranda <miranda@adacore.com>
9008 * urealp.adb (UR_Write): Reverse previous patch
9009 adding documentation on why we generate multiplications instead
9010 of divisions (needed to avoid expressions whose computation with
9011 large numbers may cause division by 0).
9013 2017-04-25 Bob Duff <duff@adacore.com>
9015 * erroutc.adb (Set_Specific_Warning_Off,
9016 Set_Warnings_Mode_Off): Use the correct source file for
9017 Stop. Was using Current_Source_File, which is only valid during
9018 parsing. Current_Source_File will have a leftover value from
9019 whatever file happened to be parsed last, because of a with_clause
9022 2017-04-25 Bob Duff <duff@adacore.com>
9024 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9025 to In_Predefined_Unit, but including GNAT units.
9026 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9027 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9028 because Should_Ignore_Pragma was not working reliably outside
9029 the parser, because Current_Source_File is not valid.
9030 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9031 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9070 Remove refactored calls and integrated code from
9071 Add_Parent_Invariants and Add_Interface_Invariants.
9073 2017-04-25 Johannes Kanig <kanig@adacore.com>
9075 * errout.adb (Output_Messages): Adjust computation of total
9077 * erroutc.adb (Error_Msg): In statistics counts, deal
9078 correctly with informational messages that are not warnings.

9095 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9098 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9100 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9101 of prefix whose type is a current instance of a synchronized
9102 type. If the prefix is an object this is an external call (or
9103 requeue) that can only access public operations of the object. The
9104 previous predicate was too restrictive, and did not allow public
9105 protected operations, only task entries.
9107 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9109 * sem_ch5.adb, fname.adb: Minor reformatting.
9111 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9113 * einfo.adb (Is_Anonymous_Access_Type): New routine.
9114 * einfo.ads Update the placement of
9115 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9117 (Is_Anonymous_Access_Type): New routine.
9118 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9119 master for an access type subject to pragma No_Heap_Finalization.
9120 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9121 allocated or deallocated does not finalization actions if the
9122 associated access type is subject to pragma No_Heap_Finalization.
9123 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9124 * par-prag.adb Pragma No_Heap_Finalization does not need special
9125 processing from the parser.
9126 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9127 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9128 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9129 No_Heap_Finalization.
9130 (Analyze_Pragma): Add processing for
9131 pragma No_Heap_Finalization. Update various error messages to
9132 use Duplication_Error.
9133 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9134 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9135 and corresponding pragma id.
9137 2017-04-25 Bob Duff <duff@adacore.com>
9139 * freeze.adb (Freeze_Record_Type): Use the
9140 underlying type of the component type to determine whether it's
9141 elementary. For representation clause purposes, a private type
9142 should behave the same as its full type.
9143 * fname.ads, fname.adb (Is_Predefined_File_Name):
9144 Make sure things like "system.ali" are recognized as predefined.
9146 2017-04-25 Javier Miranda <miranda@adacore.com>

9152 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9153 element iterator when the name is an overloaded function call,
9154 one of whose interpretations yields an array.
9156 2017-04-25 Bob Duff <duff@adacore.com>
9158 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9159 Is_Internal_Unit_Name): New functions for operating on unit
9160 names, as opposed to file names. There's some duplicated code
9161 with fname.adb, which is unfortunate, but it seems like we don't
9162 want to add dependencies here.
9163 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9164 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9165 is not a file name at all.
9166 * fname.ads, fname.adb: Document the fact that
9167 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9168 for ALI files, and fix the code so it works properly for ALI
9169 files. E.g. these should return True for "system.ali".
9171 2017-04-25 Justin Squirek <squirek@adacore.com>
9173 * exp_util.adb (Add_Invariant): Removed,
9174 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9175 and Add_Own_Invariant. (Add_Invariant_Check): Used
9176 for adding runtime checks from any kind of invariant.
9177 (Add_Inherited_Invariant): Generates invariant checks for
9178 class-wide invariants (Add_Interface_Invariants): Removed, code
9179 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

9181 Removed, code moved to Build_Invariant_Procedure_Body
9182 (Build_Invariant_Procedure_Body): Add refactored calls
9183 and integrated code from Add_Parent_Invariants and
9184 Add_Interface_Invariants.
9185 (Process_Type): Removed, the
9186 relavant code was inlined into both Add_Own_Invariant and
9187 Add_Inherited_Invariant.
9189 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9191 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9208 and Build_Invariant_Procedure_Declaration.
9209 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9210 and Build_Invariant_Procedure_Declaration from exp_ch7
9211 and break-out Is_Untagged_Private_Derivation from
9212 Build_Invariant_Procedure_Body.
9213 (Replace_Type_References):
9214 Append an extra parameter to allow for dispatching replacements
9215 and add the corrasponding logic.
9216 (Type_Invariant): Remove
9217 Replace_Typ_Refs and replace its references with calls to
9218 Replace_Type_References.
9219 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9221 2017-04-25 Bob Duff <duff@adacore.com>
9223 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9224 that returns True when appropriate.
9225 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9226 when compiling predefined files.
9227 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9228 "gnat.adc" should not be considered a predefined file name.
9229 That required (or at least encouraged) a lot of cleanup of global
9230 variable usage. We shouldn't be communicating information via
9231 the global name buffer.
9232 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9233 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9253 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
9254 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
9255 Add String_To_Name with no side effects.
9257 2017-04-25 Justin Squirek <squirek@adacore.com>
9259 * sem_ch3.adb (Analyze_Declarations): Add
9260 additional condition for edge case.

9264 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
9265 reserved words inside pragmas. This is necessary to allow the
9266 pragma name Interface to be used in pragma Ignore_Pragma.

9292 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9293 the first pass over an assignment statement with target names,
9294 to prevent the generation of subtypes (such as discriminated
9295 record components)that may carry the target name outside of the

9297 the assignment is reanalyzed in full.
9298 (Analyze_Target_Name): Handle properly class-wide types.

9312 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
9313 are now only processed when freezing occurs. Build a body only

9330 properties of the private type to the full view in case the full
9331 view derives from a parent type and inherits a DIC pragma.
9332 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9333 DIC pragma is placed at the top of a declarative region.
9335 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
9337 * a-tasatt.adb: Complete previous change and use an unsigned
9338 int to avoid overflow checks.

9343 the error message when the attribute reference is an actual in
9344 a call to a subprogram inherited from a generic formal type with
9345 unknown discriminants, which makes the subprogram and its formal
9346 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9348 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9350 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9355 * sem_attr.adb (Type_Key): Add code in the
9356 recursive Compute_Type_Key to protect against fetching the source
9357 code for Standard, in case a component of the type is declared
9358 in Standard. There was already code to do this for the original
9359 type, but not for its components.
9361 2017-04-25 Javier Miranda <miranda@adacore.com>
9363 * exp_ch3.adb (Build_Initialization_Call): Handle
9364 subtypes of private types when searching for the underlying full
9365 view of a private type.

9380 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
9381 context is a package declaration.
9382 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
9383 Analyze_Generic_Package_Declaration): ditto.

10062 (Remove_Extra_Clauses): New routine.
10063 (Report_Extra_Clauses): Remove the detection of ... => null
10064 clauses as this is now done in Remove_Extra_Clauses.
10066 2017-01-23 Ed Schonberg <schonberg@adacore.com>
10068 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10069 report on spurious overlaps between values involving a subtype
10070 with a static predicate, because the expansion of such a subtype
10071 into individual ranges in inhibited in ASIS mode.

10103 to the expected type with the appropriate check flags set.
10104 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10105 base type if the range is null. It may still be invalid if it
10106 is higher than the lower bound. This is checked later in the

10122 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10123 an object declaration for an array type with a modular index type
10124 with the size of Long_Long_Integer. Special processing is needed
10125 in this case to compute reliably the size of the object, and
10126 eventually to raise Storage_Error, when wrap-around arithmetic
10127 might compute a meangingless size for the object.
10129 2017-01-23 Justin Squirek <squirek@adacore.com>
10131 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10136 * sem_res.adb (Resolve_Call): In the part of the code where
10137 it is deciding whether to turn the call into an indexed
10138 component, avoid doing so if the call is to an instance of
10139 Unchecked_Conversion. Otherwise, the compiler turns it into an
10140 indexed component, and resolution of that turns it back into a
10141 function call, and so on, resulting in infinite recursion.
10142 * sem_util.adb (Needs_One_Actual): If the first formal has a
10143 default, then return False.
10145 2017-01-21 Eric Botcazou <ebotcazou@adacore.com>

10188 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10190 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10191 must be treated as delayed aspect even if the expression is
10192 a literal, because the aspect affects the freezing and the
10193 elaboration of the object to which it applies.

10245 returns a limited view of a type and at the point of the call the
10246 function is not declared in the extended main unit then replace
10247 it with the non-limited view, which must be available. If the
10248 called function is in the extended main unit then no action is
10249 needed since the back-end handles this case.

10271 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10272 When inheriting the SPARK_Mode of a prior expression function,

10363 * sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
10364 aspect Implicit_Dereference can be inherited by a full view if
10365 the partial view has no discriminants, because there is no way
10366 to apply the aspect to the partial view.
10367 (Build_Derived_Record_Type): If derived type renames discriminants

10459 * sem_prag.adb (Analyze_Pragma): Check for ignored pragmas first,
10460 before checking for unrecognized pragmas.

10470 declaration into the tree for GNATprove by setting its Parent
10472 * freeze.adb (Freeze_Arry_Type):In GNATprove mode, do not add

10476 (Freeze_Record_Type): In GNATprove mode, do
10477 not add the component invariants to the record type invariant
10478 procedure so that the procedure can be used to check the record
10479 type invariants if any.

10501 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
10502 type, ie. a type whose component is a character type, and the
10503 aggregate is positional, do not convert into a string literal
10504 if the index type is not an integer type, because the original
10505 type may be required in an enclosing operation.
10507 2017-01-19 Bob Duff <duff@adacore.com>
10509 * binde.adb, debug.adb: Enable new elaboration order algorithm

10518 * sem_ch7.adb Remove the with and use clauses for Exp_Ch7
10520 (Analyze_Package_Specification): Remove the

10522 now done by Analyze_Declarations.
10523 * sem_disp.adb (Check_Dispatching_Operation): DIC and Invariant
10524 procedures are never treated as primitives.
10526 2017-01-19 Yannick Moy <moy@adacore.com>

10539 * exp_ch4.adb (Expand_Concatenate): Do no enable overflow
10540 checks on the expression for the high bound of concatenation

10555 * exp_ch6.adb (Expand_Call): Remove side effects on
10556 actuals that are allocators with qualified expression since the
10557 initialization of the object is performed by means of individual
10558 statements (and hence it must be done before the call).
10560 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10562 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10563 (Build_Derived_Enumeration_Type): If the derived type inherits a
10564 dynamic predicate from its parent, the bounds of the type must
10565 freeze because an explicit constraint is constructed for the
10566 type and the corresponding range is elaborated now.
10568 2017-01-19 Arnaud Charlet <charlet@adacore.com>

10599 and has not been rewritten as a regular call because regular
10600 expansion has not taken place.
10602 2017-01-19 Bob Duff <duff@adacore.com>
10604 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10605 in case of generic formal discrete types, because it causes crashes in

10615 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
10616 Increment Warnings_Detected. It was decrementing, which is
10617 wrong since we just issued a warning message.
10618 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10619 these variables to be of subtype Nat instead of Int, because
10620 they should never be negative.

10651 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10653 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10654 selected component has a prefix that might be interpreted
10655 as a parameterless function call, but none of the candidate
10656 interpretations is parameterless, and there is a hidden homonym
10657 of the prefix that is a package.
10658 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10659 interpreted as a parameterless function call and its analysis
10660 fails, do not call Analyze_Selected_Component.
10662 2017-01-19 Steve Baird <baird@adacore.com>
10664 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10666 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with

10671 * gnat1drv.adb: minor fix of unbalanced parens in comment
10672 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10673 to visible part of the package to allow re-use in GNATprove.
10674 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10675 from repeated code of Traverse_Compilation_Unit.
10676 (Traverse_Declaration_Or_Statement): fixed detection of
10677 generic subprograms and packages; also, iteration over case
10678 statement alternatives rewritten to avoid testing if the first
10679 alternative is present (since it must be present due to Ada
10680 syntax restrictions).
10682 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10684 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
10685 returning by reference not just for subprogram body stubs,
10686 but for all subprogram cases.
10687 * sem_util.adb: Code reformatting.
10688 (Requires_Transient_Scope): Update the call to Results_Differ.

10694 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10695 identifier nodes that do not come from source, to handle properly
10696 dimensionality check within an inlined body which inclddes both
10697 original operands and rewritten operands. This removes spurious
10698 dimensionality errors in the presence of front-end inlining,
10699 as well as in SPARK mode.
10701 2017-01-16 Jakub Jelinek <jakub@redhat.com>

10741 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10742 even if entity is already set, because the node may be renalyzed
10743 after inlining transformations.

10773 (Freeze_Expr_Types): Complete previous patch since the expression
10774 of an expression-function may have iterators and loops with
10775 defining identifiers which, as part of the preanalysis of the
10776 expression, may be left decorated with itypes that will not be

10819 * binde.adb (Elab_New): New elaboration order algorithm
10820 that is expected to cause fewer ABE issues. This is a work in
10821 progress. The new algorithm is currently disabled, and can be
10822 enable by the -dp switch, or by modifying the Do_Old and Do_New
10823 etc. flags and rebuilding. Experimental code is included to
10824 compare the results of the old and new algorithms.
10825 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10826 can have multiple of these tables, so the old and new algorithms
10828 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10829 parameter of type array. This avoids the global variable, and
10830 allows bounds checking (which is normally defeated by the tables
10831 packages). It also ensures that the Elab_Order is read-only
10833 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10834 subprograms that need it, as above.
10835 * debug.adb: Document new -dp switch. Modify doc of old -do
10837 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde

10841 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10843 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10844 function is a completion, all entities referenced in the
10845 expression are frozen. As a consequence, a reference to an
10846 uncompleted private type from an enclosing scope is illegal.
10848 2017-01-13 Javier Miranda <miranda@adacore.com>
10850 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10851 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10852 expression function declaration that is a completion, its
10853 expression causes freezing (AI12-0103).
10855 2017-01-13 Vadim Godunko <godunko@adacore.com>

10908 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
10909 Iterated_Component_Present.
10910 * exp_aggr.adb: Use Choice_List throughout, to handle
10911 Iterated_Component_Associations.
10912 (Gen_Loop): Generate proper loop for an
10913 Iterated_Component_Association: loop variable has the identifier
10914 of the original association. Generate a loop even for a single
10915 component choice, in order to make loop parameter visible in
10917 (Flatten): An Iterated_Component_Association is not static.
10919 2017-01-13 Yannick Moy <moy@adacore.com>
10921 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10922 float exponentiation for statically known small negative values
10923 is the reciprocal of the exponentiation for the opposite value
10925 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10926 Ensure that the value of float exponentiation for negative values
10927 is the reciprocal of the exponentiation for the opposite value

10936 expression in delay statement as OK for volatile context.
10938 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10940 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10941 mode a choice that is a subtype with a static predicate is
10942 replaced by the values it covers. This transformation must not
10943 be performed in ASIS mode, to preserve the source for analysis.
10945 2017-01-13 Justin Squirek <squirek@adacore.com>
10947 * nlists.ads: Correct minor typo.
10949 2017-01-13 Gary Dismukes <dismukes@adacore.com>

10956 Iterated_Component_Association is a named association in an
10958 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
10959 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10960 and resolve the discrete choices and the expression of the
10962 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10963 Loop_Actions and Box_Present are attributes of
10964 N_Iterated_Component_Association nodes. Box_Present is always
10965 False in this case.
10966 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10967 has a Discrete_Choices list, as specified in the RM. A
10968 Component_Association for aggregate uses instead a Choices list.
10969 We have to live with this small inconsistency because the new
10970 construct also has a defining identifier, and there is no way
10971 to merge the two node structures.
10973 2017-01-13 Yannick Moy <moy@adacore.com>
10975 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

10983 Analyze_Declarations, to analyze and resolve the expressions of
10984 aspect specifications in the current declarative list, so that
10985 the expressions have proper entity and type info. This is needed
10986 for ASIS when there is no subsequent expansion to generate this
10987 semantic information.
10988 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10989 original expression, to suppress cascaded errors when expression
10990 has been constant-folded.
10991 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10992 ASIS mode, because there is no subsequent expansion to decorate
10995 2017-01-13 Yannick Moy <moy@adacore.com>
10997 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
10998 New function to detect when a call may be inlined or not in
11000 (Expand_Inlined_Call): Ensure that a temporary
11001 is always created in the cases where a type conversion may be
11002 needed on an input parameter in GNATprove mode, so that GNATprove
11003 sees the check to perform.
11004 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11005 when not applicable due to actual requiring type conversion
11006 with possible check but no temporary value can be copied for
11007 GNATprove to see the check.
