4 exclusions to the comment.
6 2017-12-07 Martin Sebor <msebor@redhat.com>
9 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
10 new member of struct attribute_spec.
12 2017-12-06 Simon Wright <simon@pushface.org>
15 * bindgen.adb (Gen_AdaFinal): If the restriction No_Task_Termination is
16 set, generate a null body.

31 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
33 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
34 QNX. At startup, the first mutex created has a non-zero ceiling
35 priority whatever its actual policy. This makes some tests fail
36 (c940013 for example).
38 2017-12-05 Bob Duff <duff@adacore.com>
40 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
41 Expand_Cleanup_Actions for N_Extended_Return_Statement.
42 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
43 N_Extended_Return_Statement by transforming the statements into a
44 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
45 It's too hard for Expand_Cleanup_Actions to operate directly on the
46 N_Extended_Return_Statement, because it has a different structure than
47 the other node kinds that Expand_Cleanup_Actions.
48 * exp_util.adb (Requires_Cleanup_Actions): Add support for
49 N_Extended_Return_Statement. Change "when others => return False;" to
50 "when others => raise ...;" so it's clear what nodes this function
51 handles. Use named notation where appropriate.
52 * exp_util.ads: Mark incorrect comment with ???.
54 2017-12-05 Javier Miranda <miranda@adacore.com>

77 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
78 Ada.Calendar.Clock_Time).
80 2017-12-05 Ed Schonberg <schonberg@adacore.com>

83 subprogram is overloaded, scan the list of homonyms in the same
84 scope, to find the inherited operation that may be overridden

88 2017-12-05 Bob Duff <duff@adacore.com>
90 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
91 Init_Assignment is rewritten, we need to set Assignment_OK on the new
92 node. Otherwise, we will get spurious errors when initializing via

107 2017-12-05 Nicolas Setton <setton@adacore.com>
109 * terminals.c (__gnat_setup_child_communication): As documented,
110 __gnat_setup_child_communication should not terminate - it is intended
111 to be used as the child process of a call to fork(). However, execvp
112 might actually return in some cases, for instance when attempting to
113 run a 32-bit binary on a 64-bit Linux distribution when the
114 compatibility packages are not installed. In these cases, exit the
115 program to conform to the documentation.
117 2017-12-05 Olivier Hainque <hainque@adacore.com>

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

303 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
304 assignment if it is part of an Iterated_Component_Association: the
305 analysis needs to take place once the loop structure is analyzed and
306 the loop parameter made visible, because references to it typically
307 appear in the corresponding expression. This is necessary if the
308 expression is an aggregate, because previous pre-analysis of the
309 expression does not handle nested aggregates properly.
311 2017-12-05 Bob Duff <duff@adacore.com>
313 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an

324 retrieved load address to Init_Module.
325 * s-tsmona__linux.adb (Get): Honor the new interface.
326 * s-tsmona__mingw.adb (Get): Likewise.

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

342 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
343 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
344 other back-ends can also benefit from the front-end expansion. Remove
345 test for Modify_Tree_For_C in all callers to better share code.
346 * gnat1drv.adb (Adjust_Global_Switches): Set
347 Expand_Nonbinary_Modular_Ops when generating C code.
349 2017-12-05 Ed Schonberg <schonberg@adacore.com>
351 * exp_ch5.adb (Expand_Formal_Container_Loop): Ensure that the loop
352 parameter becomes invisible after analyzing the loop, which has been

362 * exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
363 instead of the full name.
364 * sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
365 in the case of an instance of a generic.
367 2017-12-05 Arnaud Charlet <charlet@adacore.com>
369 (Adjust_Global_Switches): Create an alias GNAT_Annotate to map to

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

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

880 2017-11-09 Jerome Lambourg <lambourg@adacore.com>
882 * init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
883 as such capability is not available on the OS.

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

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

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

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

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

1016 when processing generic instances.
1018 2017-11-09 Bob Duff <duff@adacore.com>
1020 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1021 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1022 objects can have those special values. Valid_Name_Id could usefully be
1023 used all over the compiler front end, but that's too much trouble for
1024 now. If we did that, we might want to rename:
1025 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1026 For parameters of type Valid_Name_Id, remove some redundant tests,
1027 including the ones found by CodePeer. Use Is_Valid_Name instead of
1028 membership test when appropriate.
1029 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1030 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1031 "in Error_Name_Or_No_Name".

2455 2017-10-09 Bob Duff <duff@adacore.com>
2457 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2458 code so if BIPAlloc is not passed in, it will likely raise
2459 Program_Error instead of cause miscellaneous chaos.

2461 as for the other Is_B-I-P... functions.
2462 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2463 aggregate whose ancestor part is a build-in-place call returning a
2464 nonlimited type, transform the assignment to the ancestor part to use a

2467 creating an Itype for a library unit entity.
2468 (Check_Initialization): Avoid spurious error message on
2469 internally-generated call.
2470 * sem_ch5.adb (Analyze_Assignment): Handle the case where the

2474 implies >= Ada 2005.

2515 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2516 limited. This is for the case of a function call that occurs as the
2517 default for a record component.
2518 (Expand_N_Object_Declaration): Deal with the case where expansion has
2519 created an object declaration initialized with something like

2525 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2526 the attribute is an object, but it may appear within a conversion. The
2527 object itself must be retrieved when generating the range test that

2552 * exp_ch6.adb (Expand_Call_Helper): Replace with code more similar to
2554 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous

2586 (Expand_Simple_Function_Return): Remove assumption that b-i-p implies

2589 (Is_Build_In_Place_Result_Type): New function to accompany
2590 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2591 sometimes we just have the type on our hands, not the function. For
2592 now, does the same thing as the old version, so build-in-place is
2593 disabled for nonlimited types, except that you can use -gnatd.9 to
2595 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2596 accompany Is_Build_In_Place_Function and

2601 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the

2604 determine whether "return (...agg...);" is returning from a
2605 build-in-place function.

2607 Remove assumption that b-i-p implies limited (initialization of
2608 In_Place_Expansion).
2609 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2610 an unchecked conversion. Add assertions.
2611 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2612 secondary stack here, just because the type needs finalization. That

2634 b-i-p implies >= Ada 2005.
2635 * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
2636 (Expr), in case Pool_Id is not set.
2637 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2638 qualified or converted.
2639 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2640 (Param)) = N_Identifier; that's all it could be.
2641 * sinfo.ads: Comment fixes.
2642 * snames.ads-tmpl: Comment fixes.

2675 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
2676 for types in expression if the function is within a generic unit.
2677 * sem_res.adb (Resolve): In a generic context do not freeze an
2678 expression, unless it is an entity. This exception is solely for the
2679 purpose of detecting illegal uses of deferred constants in generic

2754 redundant clauses. A new parameter has also been added to force

3625 2017-09-08 Yannick Moy <moy@adacore.com>
3627 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3628 return the entity associated with the call.
3629 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3630 Replace the internal Get_Function_Id with the new
3631 Sem_Aux.Get_Called_Entity.
3632 (Iterate_Call_Parameters): New
3633 procedure to iterate on formals and actuals at the same time.
3634 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3635 Set SPARK_Mode from spec when set, for analysis
3636 of instance. Restore after analysis of instance.
3637 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3638 set, for analysis of body instance. Restored automatically at
3639 the end of the subprogram.
3640 * gnat1drv.adb (Adjust_Global_Switches): Set
3641 Check_Validity_Of_Parameters to False in GNATprove mode.
3642 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3645 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3647 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3648 (New_Copy_Tree): ...there. Reset the hash tables only if they
3649 were used in the previous invocation.
3650 * s-htable.adb: Fix typo.
3652 2017-09-08 Bob Duff <duff@adacore.com>
3654 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3656 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3658 * sem_aggr.adb: minor style fix.
3660 2017-09-08 Bob Duff <duff@adacore.com>
3662 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3663 no current source file.
3664 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3665 Print something helpful in case N is invalid.
3666 * sprint.ads: Minor comment fix.
3668 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3670 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3673 2017-09-08 Bob Duff <duff@adacore.com>
3675 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3676 Ada_2020, along the same lines as the other Ada version pragmas.
3678 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3680 * sem_ch12.adb: Minor typo fixes and reformatting.
3682 2017-09-08 Yannick Moy <moy@adacore.com>
3684 * sem_aggr.adb (Resolve_Record_Aggregate):
3685 Rewrite bounds of aggregate subexpressions which may depend on
3686 discriminants of the enclosing aggregate.
3688 2017-09-08 Yannick Moy <moy@adacore.com>
3690 * sem_ch5.adb: Prevent assertion failure on illegal code.
3692 2017-09-08 Yannick Moy <moy@adacore.com>
3694 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3695 calling Renamed_Entity on an entity which cannot be a renaming.
3697 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3699 * exp_aggr.adb: Add with & use clause for Urealp.
3700 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3701 elementary types instead of just discrete types.
3702 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3703 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3704 Be prepared for the FP zero value in the memset case. Add small
3707 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3709 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3712 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3714 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3715 of New_Copy because the latter leaves the syntactic structure of
3716 the tree inconsistent (a child is accessible through two parents)
3717 and prevents proper replication of itypes by subsequent calls
3719 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3720 New_Copy because the latter leaves the syntactic structure of the
3721 tree inconsistent (a child is accessible through two parents)
3722 and prevents proper replication of itypes by subsequent calls
3724 * sem_util.adb (In_Subtree): New routine.

3729 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3731 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3732 for aspect Default_Value is a static scalar value, but it does
3733 not freeze the type. Yhis allows for subsequent representation
3734 clauses for the type.
3736 2017-09-08 Javier Miranda <miranda@adacore.com>
3738 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3739 not add entries into the undefined reference table when we are
3740 compiling with errors ignored.
3742 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3744 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3745 check if the instance is within an enclosing instance body. The
3746 formal package was legal in the enclosing generic, and is
3747 legal in the enclosing instantiation. This optimisation may be
3748 applicable elsewhere, and it also removes spurious errors that
3749 may arise with on-the-fly processing of instantiations that
3750 contain Inline_Always subprograms.
3752 2017-09-08 Vincent Celier <celier@adacore.com>
3754 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3756 2017-09-08 Justin Squirek <squirek@adacore.com>
3758 * checks.adb (Insert_Valid_Check): Manually decorate
3759 the generated temporary for range valdity checks.
3761 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3763 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3765 2017-09-08 Justin Squirek <squirek@adacore.com>
3767 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3768 case to handle underscore flags.
3769 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3770 new procedure to handle underscores.
3772 2017-09-08 Javier Miranda <miranda@adacore.com>
3774 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3775 divisions with fixed point results to avoid generating twice
3776 the runtime check on divide by zero.
3777 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3778 not evaluated twice (once for their runtime checks and once for
3779 their regular computation).
3781 2017-09-08 Yannick Moy <moy@adacore.com>
3783 * sem_prag.adb (Analyze_Part_Of): Add missing
3784 return statements after issuing errors. Add detection of
3785 out-of-order item and single concurrent type.

3905 * a-taster.ads, a-taster.adb: Move to libgnarl
3906 * gcc-interface/Makefile.in: Remove obsolete targets. Code cleanups.
3907 Add support for files in libgnarl.
3909 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3911 * exp_ch4.adb (Expand_N_Type_Conversion): Do not apply
3912 accessibility check to an interface conversion, whose purpose
3913 is to perform a pointer adjustment in a dispatching call.
3914 * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks
3915 when the actual is a construct that involves a dereference of an
3916 expression that includes a formal of the enclosing subprogram,
3917 In such cases, the accessibility level of the actual is that of
3918 the corresponding formal, which is passed in as an additional
3919 actual in the outer call.
3921 2017-09-08 Bob Duff <duff@adacore.com>
3923 * exp_intr.adb (Add_Source_Info): Do not decode
3924 file names; they were not encoded in the first place.
3926 2017-09-08 Bob Duff <duff@adacore.com>
3928 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
3929 exceptions instead of crashes. Check for absurdly long strings
3930 and empty strings. Empty strings cause trouble because they can
3931 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3932 be empty, which causes an array index out of bounds.
3933 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
3936 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3938 * sem_util.adb (Is_CCT_Instance): allow use in
3939 the context of protected types.
3941 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3957 * exp_attr.adb (Expand_Loop_Entry_Attribute): Do
3958 not skip a loop coming from source which is rewritten into a loop.
3960 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3962 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
3963 wrapper has convention Ada, to prevent spurious warnings on
3964 unconstrained array parameters.

3987 changes for Include_Subprogram_In_Messages.
3988 * sem_ch5.adb (Check_Unreachable_Code): Supply Node parameter when
3989 generating warning message.
3991 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3993 * par-ch4.adb (P_Iterated_Component_Association): Place construct
3994 under -gnat2020 flag, given that it is a future feature of
3996 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
3997 defining identifier as referenced to prevent spurious warnings:
3998 corresponding loop is expanded into one or more loops whose
3999 variable has the same name, and the expression uses those names
4000 and not the original one.
4002 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4004 * sem_elab.adb (Check_A_Call): Do not consider
4005 references to internal variables for SPARK semantics.

4022 always copy the representation aspects onto the subtype.
4024 2017-09-08 Georges-Alex Jaloyan <jaloyan@adacore.com>
4026 * g-dynhta.adb, g-dynhta.ads (Get_First_Key, Get_Next_key):
4027 Correction of the return type from access type to option type.
4028 (Simple_HTable): Moving the Instance_Data to ads file.

4049 functions to iterate over simple hastables.
4050 (Load_Factor_HTable): Remove obsolete and inefficient implementation.
4052 2017-09-08 Javier Miranda <miranda@adacore.com>
4054 * exp_ch6.adb (Unqual_BIP_Function_Call): Adding
4055 missing checks on the presence of Entity() before checking the
4058 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4060 * sem_ch6.adb (Analyze_Expression_Function): Reorder some
4061 statements, use local variable and remove unnecessary processing.

4071 * exp_ch6.adb (Replace_Renaming_Declaration_Id): New
4072 subprogram containing code that was previously inside
4073 Make_Build_In_Place_Call_In_Object_Declaration since it is also
4074 required for one of the new subprograms.

4082 (Make_Build_In_Place_Call_In_Object_Declaration): Move the code
4083 that replaces the internal name of the renaming declaration
4084 into the new subprogram Replace_Renaming_Declaration_Id.

4105 Make_Build_In_Place_Iface_Call_In_Anonymous_Context.
4107 2017-09-08 Javier Miranda <miranda@adacore.com>
4109 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
4110 access to interface types. Remove also the accessibility check.
4112 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4114 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4115 all the types that are referenced by the expression.
4116 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4117 a completion instead of manually freezing the type of the
4119 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4121 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4123 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4124 New procedure, auxiliary to Expand_Pragma_Check, to handle
4125 references to the discriminants of a protected type within a
4126 precondition of a protected operation. This is needed because
4127 the original precondition has been analyzed in the context of
4128 the protected declaration, but in the body of the operation
4129 references to the discriminants have been replaved by references
4130 to the discriminants of the target object, and these references
4131 are only created when expanding the protected body.
4133 2017-09-08 Yannick Moy <moy@adacore.com>
4135 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4138 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4140 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4141 unchecked union, do not emit checks for its (non-existent)
4142 discriminants, or for variant parts that depend on them.
4144 2017-09-08 Justin Squirek <squirek@adacore.com>
4146 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4147 Find_Comparison_Type.Try_One_Interp): Add check for generic
4150 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4152 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4153 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4154 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4155 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4156 remaining references to AAMP_On_Target.
4158 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4160 * style.adb: Fix typo.
4162 2017-09-08 Javier Miranda <miranda@adacore.com>
4164 * einfo.adb (Underlying_Type): Add missing support for class-wide
4165 types that come from the limited view.
4166 * exp_attr.adb (Attribute_Address): Check class-wide type
4167 interfaces using the underlying type to handle limited-withed
4169 (Attribute_Tag): Check class-wide type interfaces using
4170 the underlying type to handle limited-withed types.
4172 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4174 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4175 over a subtype of a type with a static predicate, taking into
4176 account the predicate function of the parent type and the bounds
4177 given in the loop specification.
4178 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4179 a loop specification that is a subtype indication whose type mark
4180 is a type with a static predicate, inherit predicate function,
4181 used to build case statement for rewritten loop.
4183 2017-09-08 Justin Squirek <squirek@adacore.com>
4185 * lib-load.adb: Modify printing of error message to exclude file
4188 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4190 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4191 don't inline subprograms declared in both visible and private
4193 (In_Package_Spec): previously In_Package_Visible_Spec; now
4194 detects subprograms declared both in visible and private parts
4197 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4199 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4200 the type is an anonymous array in an object declaration, whose
4201 component type has an invariant, use the object declaration
4202 as the insertion point for the invariant procedure, given that
4203 there is no explicit type declaration for an anonymous array type.
4205 2017-09-08 Bob Duff <duff@adacore.com>
4207 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
4209 2017-09-08 Bob Duff <duff@adacore.com>
4211 * a-strfix.adb (Trim): Compute Low and High only if needed.
4213 2017-09-08 Justin Squirek <squirek@adacore.com>
4215 * lib-load.adb (Load_Main_Source): Add error output in the case a
4216 source file is missing.
4218 2017-09-08 Bob Duff <duff@adacore.com>
4221 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4222 Default_WCEM by default (i.e. if the encoding is not specified
4223 by the Form string).
4225 2017-09-08 Bob Duff <duff@adacore.com>
4227 * s-trasym.ads (Hexa_Traceback): If
4228 Suppress_Hex is True, print "..." instead of a hexadecimal
4230 * s-trasym.adb: Ignore No_Hex in this version.
4233 2017-09-08 Bob Duff <duff@adacore.com>
4235 * debug.adb: Minor reformatting.
4237 2017-09-08 Bob Duff <duff@adacore.com>
4239 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4240 code so it doesn't trigger an "uninit var" warning.
4242 2017-09-08 Nicolas Roche <roche@adacore.com>
4244 * s-hibaen.ads: Remove obsolete file.
4246 2017-09-08 Arnaud Charlet <charlet@adacore.com>

4263 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4265 * debug.adb (dA): Adjust comment.
4266 * gnat1drv.adb (Gnat1drv): Likewise.
4267 * opt.ads (List_Representation_Info_Extended): New variable.
4268 * repinfo.adb (List_Record_Info): Split implementation into...
4269 (Compute_Max_Length): ...this. Recurse on records if requested.
4270 (List_Record_Layout): Likewise.
4271 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4272 statement, accept '0' and set List_Representation_Info_Extended
4274 * usage.adb (Usage): Document new -gnatRe variant.
4276 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4278 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4279 Do not save the given entity in the global variable Default_Pool
4280 if the pragma appears within a generic unit.
4282 2017-09-08 Bob Duff <duff@adacore.com>
4284 * errout.adb (Delete_Warning): Do not
4285 decrement Warnings_Treated_As_Errors. This is called before
4286 Warnings_Treated_As_Errors has been incremented to account for
4287 this warning. Decrementing it here can lead to negative values
4288 of Warnings_Treated_As_Errors, raising Constraint_Error in
4289 checks-on builds, and causing the compiler to return an error
4290 code in checks-off builds.
4292 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4294 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4295 entities of named concurrent types as Ref_Id and not of anonymous
4296 concurrent objects (because callers already know when a conversion
4297 is necessary and can easily do it); also, do not expect protected
4298 types or protected objects as Context_Id (because no flow-related
4299 SPARK pragmas are attached there); reflect these changes in a
4300 more precise comment.
4302 2017-09-08 Olivier Hainque <hainque@adacore.com>
4304 * g-altive.ads: Add documentation.
4306 2017-09-08 Bob Duff <duff@adacore.com>
4308 * sem_util.ads, debug.adb: Minor comment fix.
4309 * erroutc.ads: Comment fix.
4311 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4313 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4314 for compatibility of component types of formal and actual in an
4315 instantiation of a child unit, when the component type of the
4316 formal is itself a formal of an enclosing generic.
4318 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4320 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4321 sem_prag.adb to make it available for GNATprove; for concurrent
4322 types replace custom scope climbing with Scope_Same_Or_Within; for
4323 single concurrent objects add scope climbing (with Scope_Within),
4324 which was not there (that's the primary semantic change of this
4325 commit); also, when comparing a single concurrent object with
4326 its corresponding concurrent type rely on equality of types,
4327 not of objects (because that's simpler to code).
4328 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4329 (Analyze_Global_Item): adjust special-casing of references to the
4330 current instance of a concurrent unit in the Global contracts
4331 of task types and single tasks objects; similar for references
4332 in the protected operations and entries of protected types and
4333 single protected objects (in all these cases the current instance
4334 behaves as an implicit parameter and must not be mentioned in
4335 the Global contract).
4337 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4339 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4340 function calls returning a record within a subprogram call,
4343 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4345 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4346 name that designates the current instance of a child unit in its
4347 own body and appears as the prefix of a reference to an entity
4348 local to the child unit.
4349 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4352 2017-09-08 Yannick Moy <moy@adacore.com>
4354 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that

4359 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4360 warnings on internal units in configurable run time mode.
4362 2017-09-08 Bob Duff <duff@adacore.com>
4364 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4365 representation items from interfaces that the derived type
4366 implements, not just from the parent type.
4367 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4368 this to return an empty list when there are no interfaces.
4369 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4370 * sem_attr.adb: Minor comment fix.
4372 2017-09-08 Doug Rupp <rupp@adacore.com>
4374 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
4377 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4379 * exp_ch4.adb (Expand_N_Allocator): Generate a
4380 call to Allocate_Any_Controlled when the allocation does not
4381 require any initialization.
4383 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4385 * sem_util.adb (Copy_Node_With_Replacement):
4386 Update the Renamed_Object field of a replicated object renaming
4389 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4391 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4392 conversions and components of objects. Simplified the detection
4393 of the Count attribute by identifying the corresponding run-time
4396 2017-09-08 Yannick Moy <moy@adacore.com>
4398 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4399 sem_type.adb, sinfo.ads: Minor reformatting.
4401 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4403 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4404 of Freeze_Profile, used to inhibit the freezing of the profile
4405 of an expression function declared within a nested package, when
4406 some type in the profile depends on a private type declared in
4407 an enclosing package.
4409 2017-09-08 Bob Duff <duff@adacore.com>
4411 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4412 the subunit case. It's still OK to set it in the "missing subunits"
4413 case, because that won't cause the obsolete .ali files that cause
4416 2017-09-08 Bob Duff <duff@adacore.com>
4418 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4419 unclear why this didn't cause a warning.

4458 the placement of a primitive operation O that renames an operation
4459 R declared in an inner package, and which is thus not a primitive

4760 but for all kinds of items.
4761 (Collect_Subprogram_Inputs_Outputs): Do not process formal

4896 Elab_Old and use the order chosen by Elab_Old, possibly with
4897 debugging printouts comparing the two orders." Now it means
4898 "do not run Elab_New." This is of use if there are bugs that

4943 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4945 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4946 entity of a mutable type and the right-hand side is a conditional
4947 expression, resolve the alternatives of the conditional using
4948 the base type of the target entity, because the alternatives
4949 may have distinct subtypes. This is particularly relevant if
4950 the alternatives are aggregates.
4952 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4954 * checks.adb (Apply_Predicate_Check): If the expression is an
4955 aggregate that is the RHS of an assignment, apply the check to
4956 the LHS after the assignment, rather than to the aggregate. This
4957 is more efficient than creating a temporary for the aggregate,
4958 and prevents back-end crashes when the aggregate includes a
4959 dynamic "others' association.
4961 2017-09-06 Yannick Moy <moy@adacore.com>
4963 * sem_ch12.adb (Analyze_Instance_And_Renamings):
4964 Set variable to ignore SPARK_Mode in instance before the analysis
4965 of the generated package declaration.
4967 2017-09-06 Yannick Moy <moy@adacore.com>
4969 * sem_res.adb (Resolve_Call): Do not issue a
4970 message for calls inside expression function, unless body was
4971 seen and is candidate for inlining.
4973 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4975 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
4976 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
4977 body. do not freeze the formals of the generic unit.
4979 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4981 * errout.adb (Error_Msg): Separate the
4982 treatment for warning vs. style messages in inlinings and
4983 instantiations. Prevents blowups on calls to Warn_Insertion for
4984 style messages, which should not be called in that case because
4985 Warning_Msg_Char is not set.
4987 2017-09-06 Justin Squirek <squirek@adacore.com>
4989 * sem_prag.adb (Check_VFA_Conflicts): Created
4990 to group all Volatile_Full_Access checks relating to other
4991 representation pragmas (Mark_Component_Or_Object): Created
4992 to centeralize the flagging of attributes for the record type
4993 component case, a pragma applied individually to a component, and
4995 (Process_Atomic_Independent_Shared_Volatile):
4996 Add propagation of certain pragmas to record components and move
4997 evaluation of VFA checks
4999 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5001 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
5002 Do not warn on conditions that are not obeyed for Inline_Always
5003 subprograms, when assertions are not enabled.
5005 2017-09-06 Arnaud Charlet <charlet@adacore.com>
5007 * sem_util.adb (Unique_Entity): For abstract states return their
5010 2017-09-06 Bob Duff <duff@adacore.com>
5012 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5013 that is a proper body corresponding to a stub, we defer the
5014 adjustment of the sloc until after the correct adjustment has
5015 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5016 the adjustment, because it will be outside the range in (the old,
5017 incorrect) S_Adjustment.
5018 * inline.adb: Use named notation for readability and uniformity.
5019 * sinput-l.adb: Minor improvements to debugging output printed
5021 * sinput-l.ads (Create_Instantiation_Source): Minor comment
5024 2017-09-06 Vincent Celier <celier@adacore.com>
5026 * make.adb: Do not invoke gprbuild for -bargs -P.
5028 2017-09-06 Sylvain Dailler <dailler@adacore.com>
5030 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
5031 case when Op is of kind N_Qualified_Expression. In this case,
5032 the function is called recursively on the subexpression like in
5034 * make.adb: Minor reformatting
5036 2017-09-06 Justin Squirek <squirek@adacore.com>
5038 * einfo.adb (Set_Linker_Section_Pragma): Modify
5039 Set_Linker_Section_Pragma to be consistant with the "getter"
5040 Linker_Section_Pragma.
5041 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5042 checking for container loops so that the index cursor is not
5043 directly changable by the user with the use of E_Loop_Parameter.
5044 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
5045 * sem_warn.adb (Check_References): Revert previous change.
5047 2017-09-06 Bob Duff <duff@adacore.com>

5054 * sem_prag.adb (Analyze_Depends_Global): Reinforce test on object
5055 declarations to only consider valid uses of Global/Depends those on
5056 single concurrent objects.

5078 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
5079 gnatname.adb: Remove the Project Manager from the GNAT tools.
5080 * gcc-interface/Makefile.in: ditto.
5082 2017-09-06 Bob Duff <duff@adacore.com>
5084 * sem_util.ads: Minor comment fix.
5086 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5088 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5089 Generate a freeze node for the actual of a formal package, if
5090 the actual is declared in the same unit and has a corresponding
5091 body, to prevent the current instance from being frozen before
5094 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5096 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.
5098 2017-09-06 Yannick Moy <moy@adacore.com>

5116 missing case of controlled generalized indexing.
5117 (Is_Source_Object): Use routine Strip to remove indirections.
5118 (Strip): New routine.
5120 2017-09-06 Bob Duff <duff@adacore.com>
5122 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5123 we include the proper header. Otherwise, we just declare the necessary
5124 things from the capabilities library. This is so we can build on
5125 machines without that library, while still enabling that library.
5126 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5127 simply return 0 if the library is not present, or not included
5130 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5132 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

5143 has no parameter specification and no entry index, use the entry name
5144 as the end of the generated SCO statement.
5146 2017-09-06 Steve Baird <baird@adacore.com>
5148 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5149 uses of 'Image and related attributes as having side effects in
5150 order to avoid replicating such uses.
5151 * pprint.ads (Expression_Image) Add new generic formal flag
5152 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5153 (eventually) override the default.
5154 * pprint.adb (Expression_Image) If the new flag is set, then
5155 suppress the ".all" suffix when displaying a dereference whose
5156 prefix is a use of a value-capturing compiler temp of the sort
5157 generated by Expr_Util.Remove_Side_Effects .
5158 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

5172 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
5173 so that applies to any entity.
5175 2017-09-06 Yannick Moy <moy@adacore.com>
5177 * sem_ch3.adb (Derived_Type_Declaration): Use
5178 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5180 2017-09-06 Javier Miranda <miranda@adacore.com>
5182 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5185 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5187 * sem_dim.adb (Analyze_Dimension): In an instance, a type

5190 (Dimensions_Of_Operand): Ditto.
5192 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5194 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
5195 null procedures when GNAT coverage is used, so that their (empty)
5196 bodies are properly covered.

5206 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
5207 Universal_Real and the context is a floating-point type, resolve

5215 2017-09-06 Yannick Moy <moy@adacore.com>
5217 * freeze.adb (Check_Inherited_Conditions): Rewriting
5218 of inherited preconditions and postconditions should only occur
5219 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5220 be confused with SPARK_Mode being On.
5222 2017-09-06 Yannick Moy <moy@adacore.com>

5235 on the procedure created to encapsulate the body.
5236 * sem_ch7.adb: Add with clause for GNAT.HTable.
5237 (Entity_Table_Size): New constant.
5238 (Entity_Hash): New function.
5239 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5240 (Is_Subprogram_Ref): Rename into...
5241 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5242 the table instead of bailing out on them. Scan the value of constants
5243 if it is not known at compile time.
5244 (Contains_Subprograms_Refs): Rename into...
5245 (Scan_Subprogram_Refs): ...this.
5246 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5247 Is_Public flag on subprograms if they are not actually referenced.
5248 (Hide_Public_Entities): Beef up comment on the algorithm.
5249 Reset the table of subprograms on entry.
5251 2017-09-06 Yannick Moy <moy@adacore.com>

5305 2017-09-06 Bob Duff <duff@adacore.com>
5307 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
5308 check back to the body, because SPARK is not yet ready for

5336 * sem_type.adb (Interface_Present_In_Ancestor): Within an
5337 expression function, or within a spec expression (default value,
5338 etc) a reference to an incomplete type is legal: legality of

5340 object or subprogram) is frozen.
5342 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5344 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

5358 Move Ada.Command_Line.Response_File to System.Response_File,
5359 and make Ada.Command_Line.Response_File into a rename of
5360 System.Response_File. This is to avoid having gnatbind depend
5361 Ada.Command_Line, which would damage the bootstrap process now
5362 that Ada.Command_Line contains modern Ada (the raise expression).
5363 * gnatbind.adb: Avoid dependence on
5364 Ada.Command_Line. Depend on System.Response_File instead
5365 of Ada.Command_Line.Response_File. Change one call to
5366 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5367 to Ada.Command_Line.Argument_Count to use Arg_Count.
5368 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5370 2017-09-06 Bob Duff <duff@adacore.com>

5378 "Assert(False)" with "return Iter", because if an iterable

5380 overriding or inherited default iterator.
5382 2017-09-06 Yannick Moy <moy@adacore.com>
5384 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

5393 (Write_Field15_Name): Update the output for
5394 Status_Flag_Or_Transient_Decl.
5395 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
5396 to loop parameters. Update the documentation of the attribute
5397 and the E_Loop_Parameter entity.
5398 * exp_ch7.adb (Process_Declarations): Remove the bogus guard
5399 which assumes that cursors can never be controlled.
5400 * exp_util.adb (Requires_Cleanup_Actions): Remove the bogus
5401 guard which assumes that cursors can never be controlled.

5416 * sem_attr.adb: Comment correction.
5418 2017-09-06 Gary Dismukes <dismukes@adacore.com>

5507 not retrievable as selected components.
5509 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5511 * sem_util.adb (Needs_One_Formal): The first formal of such a

5551 not visible in the object.
5552 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5553 side may be derived from that of the left-hand side (as in the
5554 case of an assignment with a change of representation) so the
5555 discriminant to be used in the retrieval of the value of the
5556 component must be the entity in the type of the right-hand side.

6131 * exp_ch6.adb (Expand_Call_Helper): When locating the
6132 accessibility entity created for an access parameter, handle
6133 properly a reference to a formal of an enclosing subprogram. if
6134 the reference appears in an inherited class-wide condition, it
6135 is the rewriting of the reference in the ancestor expression,
6136 but the accessibility entity must be that of the current formal.
6138 2017-05-02 Javier Miranda <miranda@adacore.com>
6140 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6175 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6176 procedure body for a local (sub)type declaration within a
6177 predicate function. Invariant checks do not apply to these, and
6178 the expansion of the procedure will happen in the wrong scope,
6179 leading to misplaced freeze nodes.
6181 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6183 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6184 to analyze generated actions. If the main unit is a body,

6189 * einfo.adb (Declaration_Node): flip branches of
6190 an IF statement to avoid repeated negations in its condition;

6220 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6221 Refine predicate for the case where the primitive operation
6222 is a renaming of equality. An overriding operation that is
6223 a user-defined renaming of predefined equality inherits its
6224 slot from the overridden operation. Otherwise it is treated
6225 as a predefined op and occupies the same predefined slot as
6226 equality. A call to it is transformed into a call to its alias,
6227 which is the predefined equality. A dispatching call thus uses
6228 the proper slot if operation is further inherited and called
6229 with class-wide arguments.
6231 2017-05-02 Justin Squirek <squirek@adacore.com>
6233 * errout.adb (Set_Msg_Text): Add a case to switch the message

6237 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6238 to handle new warning mode

6266 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6267 statement if the initialization call is a null procedure, as
6268 can happen with a controlled type with no explicit Initialize
6269 procedure, or an array of such.

6271 controlled components that has a trivial Initialize procedure,
6272 insert declaration for finalization counter after object

6275 finalization block and attendant declarations if component has
6276 a trivial Initialize procedure.
6277 (Make_Init_Call): Do not generate a call if controlled type has
6278 a trivial Initialize procedure.

6308 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6310 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6311 parameter Array_Comp to indicate the case of an array object
6312 with null-excluding components.
6313 * checks.adb (Null_Exclusion_Static_Checks):
6314 Call Compile_Time_Constraint_Error instead of
6315 Apply_Compile_Time_Constraint_Error in the component case. Also
6316 call that when Array_Comp is True, with an appropriate warning for
6317 the array component case. Only create an explicit initialization
6318 by null in the case of an object of a null-excluding access type
6319 (and no longer do that in the component case).
6320 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6321 Array_Comp defaulted to False. Pass Empty for the Comp
6322 actual when calling Null_Exclusion_Static_Checks in the case
6323 where Comp_Decl matches Object_Decl, because we don't have a
6324 component in that case. In the case of an object or component
6325 of an array type, pass True for Array_Comp on the recursive call

6330 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6331 compute the linux priority from the Ada priority. Call this everywhere
6332 required. In particular, the previous version was not doing this
6333 computation when setting the ceiling priority in various places. It
6334 was just converting to C.int, which results in a ceiling that is off
6337 2017-05-02 Ed Schonberg <schonberg@adacore.com>

6356 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6357 here from exp_ch9, to recognize objects whose creation requires

6426 operator /= into negation of operator = when needed.
6427 (Expand_SPARK): Call new
6428 function to expand operator /=.
6430 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6432 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6433 Simplify the expression for a fixed-fixed division to remove
6434 divisions by constants whenever possible, as an optimization
6435 for restricted targets.

6439 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6441 2017-05-02 Bob Duff <duff@adacore.com>
6443 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6444 to find primitive ops, instead of using an Identifier that will
6445 later be looked up. This is necessary because these ops are not
6446 necessarily visible at all places where we need to call them.
6447 * exp_util.ads: Minor comment fix.
6449 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6451 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6452 references are fully conformant if they are both expansions
6453 of the discriminant of a protected type, within one of the
6454 protected operations. One occurrence may be expanded into a
6455 constant declaration while the other is an input parameter to
6456 the corresponding generated subprogram.

6460 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6461 recursivly searching composite-types for null-excluding access
6462 types and verifying them.
6463 (Analyze_Object_Declaration): Add a
6464 call to Check_Null_Excluding_Components for static verification
6465 of non-initialized objects.
6466 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6467 a parameter for a composite-type's component and an extra case
6468 for printing component information.
6470 2017-05-02 Yannick Moy <moy@adacore.com>
6472 * sem_ch10.adb (Analyze_Subunit): Take
6473 configuration pragma into account when restoring appropriate
6474 pragma for analysis of subunit.

6486 array components specially.
6488 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6490 * sem_ch8.adb (Premature_Usage): If the premature usage of
6491 an entity is as the expression in its own object decaration,
6492 rewrite the reference as Any_Id to prevent cascaded errors or
6493 compiler loops when such an entity is used in an address clause.
6495 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6497 * gcc-interface/decl.c (components_to_record): Add missing guard.

6502 Put back pending fields onto the regular list if the misalignment
6503 happens to cancel itself.
6505 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6507 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6508 controlling actual in a prefixed call, preserve the original node
6509 information if the prefix itself has been rewritten, for ASIS use.
6511 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6513 * exp_ch6.adb (Insert_Post_Call_Actions):
6514 Code clean up. Insert the post-call actions after an enclosing
6515 procedure call when N denotes a function call and appears as an
6516 actual parameter in the procedure call.
6518 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6520 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6521 for the component, also reject the attribute if the component
6522 doesn't end on a byte boundary and its scalar storage order is
6523 different from that of the enclosing record type.
6525 2017-04-28 Javier Miranda <miranda@adacore.com>
6527 * atree.ads (Info_Messages): Removed.
6528 (Warning_Info_Messages): New counter.

6557 2017-04-28 Bob Duff <duff@adacore.com>
6559 * sem_util.ads, sem_util.adb (Might_Raise): New function
6560 that replaces Is_Exception_Safe, but has the opposite
6561 sense. Is_Exception_Safe was missing various cases -- calls inside
6562 a pragma Debug, calls inside an 'if' or assignment statement,
6563 etc. Might_Raise now walks the entire subtree looking for things
6565 * exp_ch9.adb (Is_Exception_Safe): Remove.
6566 (Build_Protected_Subprogram_Body): Replace call to
6567 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6568 constants where possible).
6569 * exp_ch7.adb: Rename Is_Protected_Body -->
6570 Is_Protected_Subp_Body. A protected_body is something different
6573 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

6599 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6600 Interrupt_Handler and Attach_Handler): Generate reference
6601 to protected operation to prevent spurious warnings about
6602 unreferenced entities. Previous scheme failed with style checks
6605 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6607 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6608 that follows an expression function must not be relocated to
6609 the generated body, because it applies to the code that follows.
6611 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6613 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6614 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6615 code that might violate the more stringent checking for 'Access
6616 introduced in Ada 2005.
6618 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6620 * a-cforse.adb: minor style fix in comment.
6622 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6624 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6625 initialize Block_Decls variable.
6626 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6627 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

6636 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6638 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6640 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6641 node between access types, freeze the designated type as well,
6642 so that dispatch table pointers are created in the proper scope,
6643 and not in the constructed body of the expression function.
6645 2017-04-28 Bob Duff <duff@adacore.com>
6647 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6648 value makes large compilations faster, but small compilations slower.
6650 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6652 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6654 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6656 * erroutc.adb (Compilation_Errors): Do not consider info messages
6657 as suitable warnings when warnings must be treated as errors.
6658 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6659 internally-generated packages when outputting completion
6661 * errout.adb (Output_Messages): Do not consider info messages as

6664 suitable warnings when warnings must be treated as errors.
6666 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6668 * warnsw.ads: Minor fix for incorrect wording in comment.
6670 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6672 * sem_res.adb (In_Instance_Code): New predicate in
6673 Valid_Conversion, to determine whether a type conversion appears
6674 as (or within) an actual for a formal object. Type conversions
6675 in instances are not rechecked in Valid_Conversion because
6676 visibility changes between generic location andi instance may
6677 lead to spurious errors, but conversions within an actual must be
6678 fully checked, and they are not fully resolved when pre-analyzing
6681 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6683 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6684 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6685 of the relocated node will have mangled Parent pointers.
6686 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6687 tables used in conjunction with entity and itype replication.
6688 (Visit_Entity): Rewrite the restriction on which entities

6723 (Restore_Warnings): Likewise.
6724 (Save_Warnings): Likewise.
6725 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6726 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6727 components_to_record.
6728 (gnu_field_to_gnat): New function.
6729 (warn_on_field_placement): Likewise.
6730 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6731 parameters. Rename local variables and adjust recursive call.
6732 Rework final scan of the field list and implement warnings on the
6733 problematic placement of specific sorts of fields.
6735 2017-04-27 Bob Duff <duff@adacore.com>
6737 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6742 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6743 For efficiency, cache results of Is_Internal_File_Name and
6744 Is_Predefined_File_Name in the Units table. This avoids a lot
6745 of repeated text processing.
6747 2017-04-27 Emmanuel Briot <briot@adacore.com>
6749 * g-comlin.adb (Sort_Sections): remove useless test.
6751 2017-04-27 Claire Dross <dross@adacore.com>
6753 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6754 allow the use of regular equality over elements in contracts.
6755 (Formal_Model): Ghost package containing model functions that are
6756 used in subprogram contracts.
6757 (Current_To_Last): Removed, model functions should be used instead.
6758 (First_To_Previous): Removed, model functions should be used instead.
6759 (Strict_Equal): Removed, model functions should be used instead.
6760 (No_Overlap): Removed, model functions should be used instead.
6761 (Equivalent_Keys): Functions over cursors are removed. They were
6762 awkward with explicit container parameters.
6763 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6764 allow the use of regular equality over elements in contracts.
6765 (Formal_Model): Ghost package containing model functions that

6774 * gnat1drv.adb: Code cleanup.
6776 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6778 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6779 attribute reference in a post- condition is the subprogram to
6780 which the condition applies. If the condition is inherited
6781 by a type extension, the prefix becomes a reference to the
6782 inherited operation, but there is no need to create a wrapper
6783 for this operation, because 'Result is expanded independently
6784 when elaborating the postconditions.
6786 2017-04-27 Bob Duff <duff@adacore.com>
6788 * sinput.adb: Minor code cleanup.
6789 * namet.adb (Append): Create faster versions of
6790 Append(String) and Append(Name_Id) by using slice assignment
6792 * sem_util.adb (In_Instance): Speed this up by removing
6793 unnecessary tests; Is_Generic_Instance is defined for all
6795 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6796 Remove unused function.
6797 * alloc.ads (Nodes_Initial): Use a much larger value, because
6798 the compiler was spending a lot of time copying the nodes table
6799 when it grows. This number was chosen in 1996, so is rather out
6800 of date with current memory sizes. Anyway, it's virtual memory.
6801 Get rid of Orig_Nodes_...; use Node_... instead.
6802 * atree.adb (Lock): Do not release the Nodes tables; it's a
6804 Orig_Nodes_ ==> Nodes_
6805 * nlists.adb: Orig_Nodes_ ==> Nodes_
6806 * g-table.adb: Remove unused "with" clause.
6807 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6808 not be used by clients.
6809 * g-dyntab.adb (Last_Allocated): New function
6810 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
6812 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6814 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
6816 (Subtypes_Statically_Match): Remove duplicate check.

6833 for qualified expressions, type conversions, and unchecked
6835 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
6836 processing for Ada 83 and instances.
6837 (Object_Access_Level): Merge the processing for indexed components
6838 and selected components.
6839 * uname.adb (Add_Node_Name): Merge the processing for stubs.

6849 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
6850 of Expand_Dispatching_Call. If the denoted subprogram has a
6851 class-wide precondition, this is the only precondition that
6852 applies to the call, rather that the class-wide preconditions
6853 that may apply to the body that is executed. (This is specified
6856 2017-04-27 Yannick Moy <moy@adacore.com>
6858 * gnat1drv.adb (Adjust_Global_Switches): Issue
6859 a warning in GNATprove mode if the runtime library does not
6860 support IEEE-754 floats.
6862 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6864 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6865 is itself inherited it does not carry any contract information,
6866 so examine its parent operation which is its Alias.
6868 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6870 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6871 prefix can be an object reference in which case Obj'Image (X)
6872 can only be interpreted as an indexing of the parameterless
6873 version of the attribute.
6874 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6875 an indexing or a slice operation if the attribute does not require
6876 parameters. In Ada2012 'Image also belongs in this category,
6877 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6879 2017-04-27 Yannick Moy <moy@adacore.com>
6881 * exp_ch4.adb: Minor reformatting.
6882 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
6883 disable the CodePeer and C generation modes. Similar to the
6884 opposite actions done in CodePeer mode.

6906 2017-04-27 Bob Duff <duff@adacore.com>
6908 * g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.

7423 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
7424 in gnat1 and gnatbind.
7425 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
7426 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

7434 modifications in functional containers.
7435 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7436 to improve readablity. Subprograms are separated between basic
7437 operations, constructors and properties. Universally quantified
7438 formulas in contracts are factorized in independant functions
7439 with a name and a comment. Names of parameters are improved.
7441 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7443 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7445 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7447 * sem_res.adb (Resolve_Type_Conversion): Do not
7448 install a predicate check here since this is already done during
7449 the expansion phase. Verify whether the operand satisfies the
7450 static predicate (if any) of the target type.
7451 * sem_ch3.adb (Analyze_Object_Declaration): Do
7452 not install a predicate check if the object is initialized by
7453 means of a type conversion because the conversion is subjected
7456 2017-04-27 Tristan Gingold <gingold@adacore.com>
7458 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be

7473 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7475 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7476 the loop which detects potential enclosing transient scopes. The
7477 loop now terminates much earlier as transient scopes are bounded
7478 by packages and subprograms.
7480 2017-04-27 Claire Dross <dross@adacore.com>
7482 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7483 allow the use of regular equality over elements in contracts.
7484 (Cursor): Type is now public so that it can be used in
7486 (Formal_Model): Ghost package containing
7487 model functions that are used in subprogram contracts.
7488 (Current_To_Last): Removed, model functions should be used
7490 (First_To_Previous): Removed, model functions should
7492 (Strict_Equal): Removed, model functions
7493 should be used instead.
7494 (Append): Default parameter value
7495 replaced by new wrapper to allow more precise contracts.

7499 value replaced by new wrapper to allow more precise contracts.
7500 (Prepend): Default parameter value replaced by new wrapper to
7501 allow more precise contracts.
7502 (Delete_First): Default parameter
7503 value replaced by new wrapper to allow more precise contracts.
7504 (Delete_Last): Default parameter value replaced by new wrapper

7513 Default_Initial_Condition procedure of a type under the SPARK
7514 elaboration checks umbrella.
7516 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

7525 * adaint.c (__gnat_get_current_dir): Return 0 in length if
7527 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7528 exception if getcwd failed.

7537 * debug.adb Change the documentation of switch -gnatd.s.
7538 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7539 to manage the secondary stack when an enclosing scope already
7540 performs this functionality (aka relaxed management). Switch
7541 -gnatd.s may be used to force strict management in which case
7542 the block will manage the secondary stack unconditionally. Add
7543 a guard to stop the traversal when encountering a package or a
7546 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7548 * sem_res.adb (Resolve_Call): Refine further the handling of
7549 limited views of return types in function calls. If the function
7550 that returns a limited view appears in the current unit,
7551 we do not replace its type by the non-limited view because
7552 this transformation is performed int the back-end. However,
7553 the type of the call itself must be the non-limited view, to
7554 prevent spurious resolution errors.
7556 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7558 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7559 Removed, proposed implementation using generics for class-wide
7560 preconditions proved impractical.
7561 (Class_Wide_Clone): New attribute of subprogram. Designates
7562 subprogram created for primitive operations with class-wide
7563 pre/postconditions that contain calls to other primitives. The
7564 clone holds the body of the original primitive, but the
7565 pre/postonditions do not apply to it. The original body is
7566 rewritten as a wrapper for a call to the clone.
7567 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7568 the flag is set, no code for the corresponding pre/postconditions
7569 is inserted into its body.
7571 2017-04-27 Bob Duff <duff@adacore.com>
7573 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
7574 Scalar_Storage_Order if -gnatI is given.
7575 * sem_prag.adb (Analyze_Pragma): Ignore

7617 private child of Ada.Containers used to implement all functional
7619 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7620 child of Ada.Containers. It provides functional indefinite unbounded
7621 maps which can be used as high level models for specification
7623 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7624 child of Ada.Containers. It provides functional indefinite unbounded
7625 sets which can be used as high level models for specification
7627 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7628 child of Ada.Containers. It provides functional indefinite unbounded
7629 vectors which can be used as high level models for specification
7631 * Makefile.rtl: Add new packages.
7632 * impunit.adb: Add new packages.
7634 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7636 * sem_ch4.adb: Minor reformatting.
7638 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7640 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7641 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7642 point type actual that has user-defined arithmetic primitives,
7643 when there is a previous actual for a formal package that defines
7644 a fixed-point type with the parent user-defined operator.
7646 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7648 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7649 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7650 the component type allows range checks.
7652 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7654 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7655 corresponding declaration, because formal derived types are
7656 rewritten as private extensions.
7658 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7660 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7661 dimensions of operands if node has been analyzed already, because
7662 previous analysis and dimension checking will have removed the
7663 dimension information from the operands.
7665 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7667 * debug.adb: Document the use of switch -gnatd.s.
7668 * einfo.ads Update the documentation on attribute
7669 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7670 the uses of these attributes from certain entities.

7672 which determines whether the block should continue to manage
7673 the secondary stack.

7727 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7728 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7729 Ada_2012 instead of Ada_2005 to be compatible with the above
7731 * bindgen.adb: Silence new warning on pragma Ada_95.
7733 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7735 * checks.adb (Generate_Range_Check): Revert part of previous change.

7746 Fix spelling mistakes.
7748 2017-04-25 Bob Duff <duff@adacore.com>
7750 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7751 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7752 for source buffers. Fix misc obscure bugs.
7753 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7754 checking, for source buffers. Modify representation clause for
7755 Source_File_Record as appropriate. Move Source_File_Index_Table
7756 from spec to body, because it is not used outside the body.
7757 Move Set_Source_File_Index_Table into the private part, because
7758 it is used only in the body and in children. Use trickery to
7759 modify the dope in the generic instantiation case. It's ugly,
7760 but not as ugly as the previous method. Fix documentation.
7761 Remove obsolete code.

7777 expander is not active or when index/range checks are suppressed
7779 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7780 Remove variants that include a Supress parameter. These routines
7781 are never used, and were introduced before the current scope-based
7782 check suppression method.
7784 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

7804 is now carried out by Null_Status.
7805 (Null_Status): New routine.

7812 error on the return type of an expression function that is a
7813 completion, if the type is derived from a generic formal type.
7815 2017-04-25 Ed Schonberg <schonberg@adacore.com>

7833 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7834 the Internal_Source buffer. This removes the incorrect call to "="
7835 the customer noticed.
7836 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7837 eventually need to eliminate them altogether. Or else get rid
7838 of zero-origin addressing.

8122 further expansion for the unchecked union.
8123 (Expand_Attribute_Reference, case 'Write): If the type is
8124 an unchecked_union, check whether enclosing scope is a Write
8125 subprogram. Replace attribute with a Raise_Program_Error if the
8126 discriminants of the unchecked_union type have not default values
8127 because such a use is erroneous..

8214 When resolving against any fixed type, set the type of the
8215 operand as universal real when the operand is a multiplication
8216 or a division where both operands are of any fixed type.
8217 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the
8218 placement of an error message by pointing to the operand of a
8219 type conversion rather than the conversion itself.
8221 2017-04-25 Thomas Quinot <quinot@adacore.com>
8223 * sem_ch13.adb (Build_Predicate_Function_Declaration): Set

8289 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
8290 overlap if the two formals have different types, because formally
8291 the corresponding actuals cannot designate the same objects.
8293 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8295 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
8296 dimensions are present from context, use them. b) If operand is
8297 a static constant rewritten as a literal, obtain the dimensions

8326 2017-04-25 Justin Squirek <squirek@adacore.com>
8328 * exp_ch3.adb (Freeze_Type): Add condition to always treat
8329 interface types as a partial view of a private type for the
8330 generation of invariant procedure bodies.
8331 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
8332 Add a condition to get the Corresponding_Record_Type for
8333 concurrent types, add condition to return in the absence of a

8335 and add call to Replace_References.
8336 (Add_Interface_Invariatns),
8337 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
8338 to including the working type T.
8339 (Add_Own_Invariants): Remove
8340 legacy condition for separate units, remove dispatching for ASIS
8341 and save a copy of the expression in the pragma expression.
8342 (Build_Invariant_Procedure_Body): Default initalize vars,
8343 remove return condition on interfaces, always use the
8344 private type for interfaces, and move the processing of types
8345 until after the processing of invariants for the full view.
8346 (Build_Invariant_Procedure_Declaration): Remove condition
8347 to return if an interface type is encountered and add
8348 condition to convert the formal parameter to its class-wide
8349 counterpart if Work_Typ is abstract.
8350 (Replace_Type): Add call to Remove_Controlling_Arguments.
8351 (Replace_Type_Ref): Remove class-wide dispatching for the current
8352 instance of the type.
8353 (Replace_Type_References): Remove parameter "Derived"
8354 (Remove_Controlling_Arguments): Created in order to removing
8355 the controlliong argument from calls to primitives in the case
8356 of the formal parameter being an class-wide abstract type.
8357 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
8358 to the change made to Freeze_Type in exp_ch3. Add a condition
8359 to treat interface types as a partial view.
8360 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
8361 to Build_Invariant_Procedure_Declaration to properly generate a
8362 "partial" invariant procedure when Typ is an interface.

8366 * a-numeri.ads: Go back to using brackets encoding for the Greek
8369 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8371 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8372 (10-15): if derived type T with progenitors is abstract,
8373 and primitive P of this type inherits non-trivial classwide
8374 preconditions from both a parent operation and from an interface
8375 operation, then the inherited operation is abstract if the parent
8376 operation is not null.
8377 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8378 with Covered_Interface_Op to yield the actual interface operation
8379 that is implemented by a given inherited operation.

8406 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8407 dereference is introduced for the object, and the object is
8408 overloaded, do not check whether it is aliased, because it may
8409 include an implicit dereference.
8410 * sem_type.adb (Disambiguate): If two interpretations are access
8411 attribute types with the same designated type keep either of
8412 them and do not report an ambiguity. A true ambiguity will be
8415 2017-04-25 Bob Duff <duff@adacore.com>
8417 * a-numeri.ads: Change the encoding of Greek letter Pi from
8418 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8419 to indicate the encoding. We considered using a byte order mark
8420 (BOM), but that causes various trouble (misc software eats the
8421 BOM, if you have a patch with a BOM, then it's not at the start
8422 of the patch, so it's not a BOM, the BOM affects with-ing files,

8466 enforce legality rule on classwide preconditions inherited from
8467 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8468 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8469 subprogram need not be dispatching if it appears in a precondition
8470 for an abstract or null subprogram.
8472 2017-04-25 Gary Dismukes <dismukes@adacore.com>

8484 (Is_Predefined_File_Name): Likewise. Adjust comment.
8486 2017-04-25 Bob Duff <duff@adacore.com>
8488 * exp_aggr.adb (Component_Count): Protect the
8489 arithmetic from attempting to convert a value >= 2**31 to Int,
8490 which would otherwise raise Constraint_Error.
8492 2017-04-25 Bob Duff <duff@adacore.com>
8494 * opt.ads (Locking_Policy): Fix incorrect documentation. The

8521 the corresponding spec or the body must ignore all SPARK_Mode
8522 pragmas found within.
8523 (Analyze_Subprogram_Declaration): Mark
8524 the spec when it needs to ignore all SPARK_Mode pragmas found
8525 within to allow the body to infer this property in case it is
8526 instantiated or inlined later.
8527 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8528 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8529 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8530 when the corresponding spec also ignored all SPARK_Mode pragmas
8532 (Analyze_Package_Declaration): Mark the spec when

8588 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8589 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8590 variable and set it to True whenever the main hash table is
8591 populated. Short- circuit the Assoc function if it is false
8592 and add associated guards.
8594 2017-04-25 Olivier Hainque <hainque@adacore.com>
8596 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8597 specs without elaboration code that have an elaboration counter
8598 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8599 * sem_ch10.adb (Analyze_Compilation_Unit):
8600 Set_Elaboration_Entity_Required when requested to preserve
8601 control flow, to ensure the unit elaboration is materialized at
8602 bind time, resulting in the inclusion of the unit object file
8603 in the executable closure at link time.
8605 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8607 * exp_dbug.adb: In Debug_Renaming_Declaration,
8608 when dealing with indexed component, accept to produce a renaming
8609 symbol when the index is an IN parameter or when it is a name
8610 defined in an outer scope.
8612 2017-04-25 Yannick Moy <moy@adacore.com>
8614 * errout.adb (Error_Msg): Adapt continuation
8615 message in instantiations and inlined bodies for info messages.
8617 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8619 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8620 Use direct 4-character slice comparisons.
8622 pragma Inline. (Has_Suffix): Delete.
8623 (Is_Internal_File_Name):
8624 Test Is_Predefined_File_Name first.

8629 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8631 * checks.adb (Insert_Valid_Check): Code cleanup.
8632 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8633 (Expand_Actuals): Generate proper copy-back for a validation
8634 variable when it acts as the argument of a type conversion.
8635 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8636 predicate to operate on type qualifications.
8638 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8640 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8643 2017-04-25 Bob Duff <duff@adacore.com>
8645 * sem_prag.adb (No_Return): Give an error if the pragma applies
8646 to a body. Specialize the error for the specless body case,
8647 as is done for (e.g.) pragma Convention.
8648 * debug.adb: Add switch -gnatd.J to disable the above legality
8649 checks. This is mainly for use in our test suite, to avoid
8650 rewriting a lot of illegal (but working) code. It might also
8651 be useful to customers. Under this switch, if a pragma No_Return
8652 applies to a body, and the procedure raises an exception (as it
8653 should), the pragma has no effect. If the procedure does return,
8654 execution is erroneous.
8656 2017-04-25 Bob Duff <duff@adacore.com>
8658 * exp_ch6.adb (Expand_Actuals): This is the
8659 root of the problem. It took N as an 'in out' parameter, and in
8660 some cases, rewrote N, but then set N to Original_Node(N). So
8661 the node returned in N had no Parent. The caller continued
8662 processing of this orphaned node. In some cases that caused a
8663 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8664 and trips over the Empty Parent). The solution is to make N an
8665 'in' parameter. Instead of rewriting it, return the list of
8666 post-call actions, so the caller can do the rewriting later,
8667 after N has been fully processed.
8668 (Expand_Call_Helper): Move most of Expand_Call here. It has
8669 too many premature 'return' statements, and we want to do the
8670 rewriting on return.
8671 (Insert_Post_Call_Actions): New procedure to insert the post-call
8672 actions in the appropriate place. In the problematic case,
8673 that involves rewriting N as an Expression_With_Actions.
8674 (Expand_Call): Call the new procedures Expand_Call_Helper and
8675 Insert_Post_Call_Actions.
8677 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8679 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8680 properly type derived from generic formal types, to handle
8681 properly modified version of ACATS 4.1B B611017.
8683 2017-04-25 Javier Miranda <miranda@adacore.com>
8685 * exp_unst.adb (Subp_Index): Adding missing
8686 support for renamings and functions that return a constrained
8687 array type (i.e. functions for which the frontend built a
8688 procedure with an extra out parameter).
8690 2017-04-25 Pascal Obry <obry@adacore.com>
8692 * s-string.adb: Minor code clean-up.
8694 2017-04-25 Bob Duff <duff@adacore.com>

8701 2017-04-25 Bob Duff <duff@adacore.com>
8703 * prep.adb (Preprocess): Remove incorrect
8704 Assert. Current character can be ASCII.CR.
8706 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8708 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8709 convention Stdcall, which has a number of exceptions. Convention
8710 is legal on a component declaration whose type is an anonymous
8711 access to subprogram.
8713 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8715 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8716 (Try_One_Prefix_Interpretation): Use the base type when dealing
8717 with a subtype created for purposes of constraining a private
8718 type with discriminants.
8720 2017-04-25 Javier Miranda <miranda@adacore.com>

8724 dispatching primitives (Restore_Warnings): Restore warning on
8725 late dispatching primitives (Save_Warnings): Save warning on late
8726 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8727 to enable/disable this warning.
8728 (WA_Warnings): Set warning on late dispatching primitives.
8729 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8730 that its parent type has a private extension.
8731 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8733 * usage.adb: Document -gnatw.j and -gnatw.J.
8735 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8737 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8740 2017-04-25 Bob Duff <duff@adacore.com>
8742 * binde.adb (Validate): Do not pass dynamic strings
8743 to pragma Assert, because older compilers do not support that.
8745 2017-04-25 Bob Duff <duff@adacore.com>
8747 * s-fileio.adb (Close): When a temp file is
8748 closed, delete it and clean up its Temp_File_Record immediately,
8749 rather than waiting until later.
8750 (Temp_File_Record): Add File
8751 component, so Close can know which Temp_File_Record corresponds
8752 to the file being closed.
8753 (Delete): Don't delete temp files,
8754 because they are deleted by Close.
8755 (Open): Set the File component
8756 of Temp_File_Record. This requires moving the creation of the
8757 Temp_File_Record to the end, after the AFCB has been created.
8759 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8761 * checks.adb (Insert_Valid_Check): Do not generate
8762 a validity check when inside a generic.

8776 concerning inheritance of class-wide preconditions do not apply
8779 2017-04-25 Bob Duff <duff@adacore.com>
8781 * s-ficobl.ads: Minor comment fix.
8783 2017-04-25 Yannick Moy <moy@adacore.com>
8785 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8786 conversions from float to integer in GNATprove mode.
8787 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8788 to call Apply_Type_Conversion_Checks, so that range checks
8789 are properly positioned when needed on conversions, including
8790 when converting from float to integer. (Determine_Range): In
8791 GNATprove mode, take into account the possibility of conversion
8792 from float to integer.
8793 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8794 check on conversions from fixed-point to integer, not anymore
8795 on conversions from floating-point to integer, when in GNATprove
8798 2017-04-25 Yannick Moy <moy@adacore.com>
8800 * checks.adb (Determine_Range_R): Special case type conversions
8801 from integer to float in order to get bounds in that case too.
8802 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8803 mode, for computations involved in interval checking.

8817 * exp_attr.adb (Make_Range_Test): Add processing for validation
8818 variables to avoid extra reads and copies of the prefix.
8819 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8820 variables in order to reflect any changes done in the variable
8821 back into the original object.
8822 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8823 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8829 generate Finalize_Address routines for CodePeer.
8831 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8833 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8834 Analyze_Pre_Post_Condition, to implement the legality checks
8835 mandated by AI12-0131: Pre'Class shall not be specified for an
8836 overriding primitive subprogram of a tagged type T unless the
8837 Pre'Class aspect is specified for the corresponding primitive
8838 subprogram of some ancestor of T.
8840 2017-04-25 Bob Duff <duff@adacore.com>
8842 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8843 is redundant, set its Used_Operations to empty. This is only
8844 necessary for use clauses that appear in the parent of a generic
8845 child unit, because those use clauses get reanalyzed when we
8846 instantiate the generic, and we don't want the Used_Operations
8847 carried over from the original context (where it was probably
8850 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8852 * exp_ch6.adb: Minor reformatting.

8863 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8865 * sem_ch8.adb (Find_Type): For an attribute reference
8866 'Class, if prefix type is synchronized and previous errors
8867 have suppressed the creation of the corresponding record type,
8868 create a spurious class-wide for the synchonized type itself,
8869 to catch other misuses of the attribute
8871 2017-04-25 Steve Baird <baird@adacore.com>
8873 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode

8877 if CodePeer_Mode is True, then don't generate the
8878 tag checks for the result of call to an instance of
8879 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8880 descendant of" check and the accessibility check).
8882 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8884 * sem_ch13.adb: Code cleanups.
8885 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

8890 * exp_ch4.adb (Library_Level_Target): New function.
8891 (Expand_Concatenate): When optimization is enabled, also expand
8892 the operation out-of-line if the concatenation is present within
8893 the expression of the declaration of a library-level object and
8894 not only if it is the expression of the declaration.
8896 2017-04-25 Bob Duff <duff@adacore.com>
8898 * freeze.adb (Freeze_Object_Declaration): Do
8899 not Remove_Side_Effects if there is a pragma Linker_Section,
8900 because in that case we want static initialization in the
8901 appropriate section.
8903 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8905 * exp_dbug.adb: Minor rewording and reformatting.

8910 handle the proposed changes to rules concerning potentially
8911 unevaluated expressions, to include selected components that
8912 do not depend on discriminants, and indexed components with
8914 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8915 predicate in quantified expression, and fix bugs in the handling
8916 of case expressions and membership test.
8917 (Analyze_Attribute_Old_Result): use new predicate.
8918 (Analyze_Attribute, case Loop_Entry): ditto.
8920 2017-04-25 Bob Duff <duff@adacore.com>
8922 * s-secsta.adb (SS_Info): Add a comment
8923 explaining why we don't need to walk all the chunks in order to

8958 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8959 internal calls that appear in preconditions of protected
8960 operations, in default values for same, and in contract guards
8961 for contract cases in SPARK.
8963 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8965 * a-numaux.ads: Fix description of a-numaux-darwin

8972 * a-numaux-x86.ads: Fix package description.
8973 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8974 (Reduce): Adjust and complete description. Call Is_Nan instead of
8975 testing manually. Use an integer temporary to hold rounded value.
8976 * a-numaux-darwin.adb (Reduce): Likewise.
8977 (Is_Nan): New function.
8979 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8981 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8982 on analysis of prefix whose type is a current instance of a

8988 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8989 the identity of callable entities therein, because they have been
8990 properly resolved, and prefixed calls may have been rewritten
8993 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8995 * exp_ch3.adb (Build_Init_Statements): Convert
8996 the expression of the pragma/aspect Secondary_Stack_Size to

9009 * s-osinte-freebsd.ads: Minor comment tweaks
9011 2017-04-25 Javier Miranda <miranda@adacore.com>
9013 * urealp.adb (UR_Write): Reverse previous patch
9014 adding documentation on why we generate multiplications instead
9015 of divisions (needed to avoid expressions whose computation with
9016 large numbers may cause division by 0).
9018 2017-04-25 Bob Duff <duff@adacore.com>
9020 * erroutc.adb (Set_Specific_Warning_Off,
9021 Set_Warnings_Mode_Off): Use the correct source file for
9022 Stop. Was using Current_Source_File, which is only valid during
9023 parsing. Current_Source_File will have a leftover value from
9024 whatever file happened to be parsed last, because of a with_clause
9027 2017-04-25 Bob Duff <duff@adacore.com>
9029 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9030 to In_Predefined_Unit, but including GNAT units.
9031 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9032 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9033 because Should_Ignore_Pragma was not working reliably outside
9034 the parser, because Current_Source_File is not valid.
9035 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9036 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9100 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9103 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9105 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9106 of prefix whose type is a current instance of a synchronized
9107 type. If the prefix is an object this is an external call (or
9108 requeue) that can only access public operations of the object. The
9109 previous predicate was too restrictive, and did not allow public
9110 protected operations, only task entries.
9112 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9114 * sem_ch5.adb, fname.adb: Minor reformatting.
9116 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9118 * einfo.adb (Is_Anonymous_Access_Type): New routine.
9119 * einfo.ads Update the placement of
9120 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9122 (Is_Anonymous_Access_Type): New routine.
9123 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9124 master for an access type subject to pragma No_Heap_Finalization.
9125 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9126 allocated or deallocated does not finalization actions if the
9127 associated access type is subject to pragma No_Heap_Finalization.
9128 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9129 * par-prag.adb Pragma No_Heap_Finalization does not need special
9130 processing from the parser.
9131 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9132 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9133 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9134 No_Heap_Finalization.
9135 (Analyze_Pragma): Add processing for
9136 pragma No_Heap_Finalization. Update various error messages to
9137 use Duplication_Error.
9138 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9139 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9140 and corresponding pragma id.
9142 2017-04-25 Bob Duff <duff@adacore.com>
9144 * freeze.adb (Freeze_Record_Type): Use the
9145 underlying type of the component type to determine whether it's
9146 elementary. For representation clause purposes, a private type
9147 should behave the same as its full type.
9148 * fname.ads, fname.adb (Is_Predefined_File_Name):
9149 Make sure things like "system.ali" are recognized as predefined.
9151 2017-04-25 Javier Miranda <miranda@adacore.com>

9157 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9158 element iterator when the name is an overloaded function call,
9159 one of whose interpretations yields an array.
9161 2017-04-25 Bob Duff <duff@adacore.com>
9163 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9164 Is_Internal_Unit_Name): New functions for operating on unit
9165 names, as opposed to file names. There's some duplicated code
9166 with fname.adb, which is unfortunate, but it seems like we don't
9167 want to add dependencies here.
9168 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9169 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9170 is not a file name at all.
9171 * fname.ads, fname.adb: Document the fact that
9172 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9173 for ALI files, and fix the code so it works properly for ALI
9174 files. E.g. these should return True for "system.ali".
9176 2017-04-25 Justin Squirek <squirek@adacore.com>
9178 * exp_util.adb (Add_Invariant): Removed,
9179 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9180 and Add_Own_Invariant. (Add_Invariant_Check): Used
9181 for adding runtime checks from any kind of invariant.
9182 (Add_Inherited_Invariant): Generates invariant checks for
9183 class-wide invariants (Add_Interface_Invariants): Removed, code
9184 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

9187 (Build_Invariant_Procedure_Body): Add refactored calls
9188 and integrated code from Add_Parent_Invariants and
9189 Add_Interface_Invariants.
9190 (Process_Type): Removed, the
9191 relavant code was inlined into both Add_Own_Invariant and
9192 Add_Inherited_Invariant.
9194 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9196 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9213 and Build_Invariant_Procedure_Declaration.
9214 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9215 and Build_Invariant_Procedure_Declaration from exp_ch7
9216 and break-out Is_Untagged_Private_Derivation from
9217 Build_Invariant_Procedure_Body.
9218 (Replace_Type_References):
9219 Append an extra parameter to allow for dispatching replacements
9220 and add the corrasponding logic.
9221 (Type_Invariant): Remove
9222 Replace_Typ_Refs and replace its references with calls to
9223 Replace_Type_References.
9224 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9226 2017-04-25 Bob Duff <duff@adacore.com>
9228 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9229 that returns True when appropriate.
9230 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9231 when compiling predefined files.
9232 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9233 "gnat.adc" should not be considered a predefined file name.
9234 That required (or at least encouraged) a lot of cleanup of global
9235 variable usage. We shouldn't be communicating information via
9236 the global name buffer.
9237 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9238 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9258 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
9259 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
9260 Add String_To_Name with no side effects.
9262 2017-04-25 Justin Squirek <squirek@adacore.com>
9264 * sem_ch3.adb (Analyze_Declarations): Add
9265 additional condition for edge case.

9269 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
9270 reserved words inside pragmas. This is necessary to allow the
9271 pragma name Interface to be used in pragma Ignore_Pragma.

9297 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9298 the first pass over an assignment statement with target names,
9299 to prevent the generation of subtypes (such as discriminated
9300 record components)that may carry the target name outside of the

9302 the assignment is reanalyzed in full.
9303 (Analyze_Target_Name): Handle properly class-wide types.

9335 properties of the private type to the full view in case the full
9336 view derives from a parent type and inherits a DIC pragma.
9337 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9338 DIC pragma is placed at the top of a declarative region.
9340 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
9342 * a-tasatt.adb: Complete previous change and use an unsigned
9343 int to avoid overflow checks.
9345 2017-04-25 Ed Schonberg <schonberg@adacore.com>

9348 the error message when the attribute reference is an actual in
9349 a call to a subprogram inherited from a generic formal type with
9350 unknown discriminants, which makes the subprogram and its formal
9351 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9353 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9355 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9360 * sem_attr.adb (Type_Key): Add code in the
9361 recursive Compute_Type_Key to protect against fetching the source
9362 code for Standard, in case a component of the type is declared
9363 in Standard. There was already code to do this for the original
9364 type, but not for its components.
9366 2017-04-25 Javier Miranda <miranda@adacore.com>
9368 * exp_ch3.adb (Build_Initialization_Call): Handle
9369 subtypes of private types when searching for the underlying full
9370 view of a private type.

9385 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
9386 context is a package declaration.
9387 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
9388 Analyze_Generic_Package_Declaration): ditto.

10062 (Check_Dependency_Clause): Properly detect a match between two
10063 'Result attributes. Update the various post-match cases to use

10067 (Remove_Extra_Clauses): New routine.
10068 (Report_Extra_Clauses): Remove the detection of ... => null
10069 clauses as this is now done in Remove_Extra_Clauses.
10071 2017-01-23 Ed Schonberg <schonberg@adacore.com>
10073 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10074 report on spurious overlaps between values involving a subtype
10075 with a static predicate, because the expansion of such a subtype
10076 into individual ranges in inhibited in ASIS mode.

10108 to the expected type with the appropriate check flags set.
10109 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10110 base type if the range is null. It may still be invalid if it
10111 is higher than the lower bound. This is checked later in the

10127 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10128 an object declaration for an array type with a modular index type
10129 with the size of Long_Long_Integer. Special processing is needed
10130 in this case to compute reliably the size of the object, and
10131 eventually to raise Storage_Error, when wrap-around arithmetic
10132 might compute a meangingless size for the object.
10134 2017-01-23 Justin Squirek <squirek@adacore.com>
10136 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10141 * sem_res.adb (Resolve_Call): In the part of the code where
10142 it is deciding whether to turn the call into an indexed
10143 component, avoid doing so if the call is to an instance of
10144 Unchecked_Conversion. Otherwise, the compiler turns it into an
10145 indexed component, and resolution of that turns it back into a
10146 function call, and so on, resulting in infinite recursion.
10147 * sem_util.adb (Needs_One_Actual): If the first formal has a
10148 default, then return False.
10150 2017-01-21 Eric Botcazou <ebotcazou@adacore.com>

10193 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10195 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10196 must be treated as delayed aspect even if the expression is
10197 a literal, because the aspect affects the freezing and the
10198 elaboration of the object to which it applies.

10250 returns a limited view of a type and at the point of the call the
10251 function is not declared in the extended main unit then replace
10252 it with the non-limited view, which must be available. If the
10253 called function is in the extended main unit then no action is
10254 needed since the back-end handles this case.

10268 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
10269 base type differs from that of the completion and the private

10276 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10277 When inheriting the SPARK_Mode of a prior expression function,

10368 * sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
10369 aspect Implicit_Dereference can be inherited by a full view if
10370 the partial view has no discriminants, because there is no way
10371 to apply the aspect to the partial view.
10372 (Build_Derived_Record_Type): If derived type renames discriminants

10464 * sem_prag.adb (Analyze_Pragma): Check for ignored pragmas first,
10465 before checking for unrecognized pragmas.

10470 * exp_ch7.adb (Build_Invariant_Procedure_Body): Semi-insert the
10471 body into the tree for GNATprove by setting its Parent field. The

10473 the composite type's invariant procedure in GNATprove mode.
10474 (Build_Invariant_Procedure_Declaration): Semi-insert the
10475 declaration into the tree for GNATprove by setting its Parent
10477 * freeze.adb (Freeze_Arry_Type):In GNATprove mode, do not add

10479 so that the procedure can be used to check the array type
10481 (Freeze_Record_Type): In GNATprove mode, do
10482 not add the component invariants to the record type invariant
10483 procedure so that the procedure can be used to check the record
10484 type invariants if any.

10506 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
10507 type, ie. a type whose component is a character type, and the
10508 aggregate is positional, do not convert into a string literal
10509 if the index type is not an integer type, because the original
10510 type may be required in an enclosing operation.
10512 2017-01-19 Bob Duff <duff@adacore.com>
10514 * binde.adb, debug.adb: Enable new elaboration order algorithm
10515 by default. -dp switch reverts to the old algorithm.

10523 * sem_ch7.adb Remove the with and use clauses for Exp_Ch7
10525 (Analyze_Package_Specification): Remove the

10528 * sem_disp.adb (Check_Dispatching_Operation): DIC and Invariant
10529 procedures are never treated as primitives.
10531 2017-01-19 Yannick Moy <moy@adacore.com>

10544 * exp_ch4.adb (Expand_Concatenate): Do no enable overflow
10545 checks on the expression for the high bound of concatenation

10560 * exp_ch6.adb (Expand_Call): Remove side effects on
10561 actuals that are allocators with qualified expression since the
10562 initialization of the object is performed by means of individual
10563 statements (and hence it must be done before the call).
10565 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10567 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10568 (Build_Derived_Enumeration_Type): If the derived type inherits a
10569 dynamic predicate from its parent, the bounds of the type must
10570 freeze because an explicit constraint is constructed for the
10571 type and the corresponding range is elaborated now.
10573 2017-01-19 Arnaud Charlet <charlet@adacore.com>

10604 and has not been rewritten as a regular call because regular
10605 expansion has not taken place.
10607 2017-01-19 Bob Duff <duff@adacore.com>
10609 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10610 in case of generic formal discrete types, because it causes crashes in

10620 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
10621 Increment Warnings_Detected. It was decrementing, which is
10622 wrong since we just issued a warning message.
10623 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10624 these variables to be of subtype Nat instead of Int, because
10625 they should never be negative.

10656 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10658 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10659 selected component has a prefix that might be interpreted
10660 as a parameterless function call, but none of the candidate
10661 interpretations is parameterless, and there is a hidden homonym
10662 of the prefix that is a package.
10663 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10664 interpreted as a parameterless function call and its analysis
10665 fails, do not call Analyze_Selected_Component.
10667 2017-01-19 Steve Baird <baird@adacore.com>
10669 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10671 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with

10676 * gnat1drv.adb: minor fix of unbalanced parens in comment
10677 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10678 to visible part of the package to allow re-use in GNATprove.
10679 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10680 from repeated code of Traverse_Compilation_Unit.
10681 (Traverse_Declaration_Or_Statement): fixed detection of
10682 generic subprograms and packages; also, iteration over case
10683 statement alternatives rewritten to avoid testing if the first
10684 alternative is present (since it must be present due to Ada
10685 syntax restrictions).
10687 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10689 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
10690 returning by reference not just for subprogram body stubs,
10691 but for all subprogram cases.
10692 * sem_util.adb: Code reformatting.
10693 (Requires_Transient_Scope): Update the call to Results_Differ.

10699 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10700 identifier nodes that do not come from source, to handle properly
10701 dimensionality check within an inlined body which inclddes both
10702 original operands and rewritten operands. This removes spurious
10703 dimensionality errors in the presence of front-end inlining,
10704 as well as in SPARK mode.
10706 2017-01-16 Jakub Jelinek <jakub@redhat.com>
10709 * gcc-interface/lang.opt (gant, gnatO, gnat): Add Driver flag.

10745 * scil_ll.adb: Minor style fix in comment.
10746 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10747 even if entity is already set, because the node may be renalyzed
10748 after inlining transformations.
10750 2017-01-13 Javier Miranda <miranda@adacore.com>
10752 * sem_res.adb (Resolve_Call): Do not establish a transient scope
10753 for a call to inlinable expression function (since the call will
10754 be replaced by its returned object).

10777 * sem_ch6.adb (Cloned_Expression): New subprogram.
10778 (Freeze_Expr_Types): Complete previous patch since the expression
10779 of an expression-function may have iterators and loops with
10780 defining identifiers which, as part of the preanalysis of the
10781 expression, may be left decorated with itypes that will not be
10782 available in the tree passed to the backend.
10784 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10822 2017-01-13 Bob Duff <duff@adacore.com>
10824 * binde.adb (Elab_New): New elaboration order algorithm
10825 that is expected to cause fewer ABE issues. This is a work in
10826 progress. The new algorithm is currently disabled, and can be
10827 enable by the -dp switch, or by modifying the Do_Old and Do_New
10828 etc. flags and rebuilding. Experimental code is included to
10829 compare the results of the old and new algorithms.
10830 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10831 can have multiple of these tables, so the old and new algorithms
10833 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10834 parameter of type array. This avoids the global variable, and
10835 allows bounds checking (which is normally defeated by the tables
10836 packages). It also ensures that the Elab_Order is read-only
10838 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10839 subprograms that need it, as above.
10840 * debug.adb: Document new -dp switch. Modify doc of old -do
10842 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10843 and Bindgen. Move writing of closure (-R and -Ra switches)

10846 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10848 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10849 function is a completion, all entities referenced in the
10850 expression are frozen. As a consequence, a reference to an
10851 uncompleted private type from an enclosing scope is illegal.
10853 2017-01-13 Javier Miranda <miranda@adacore.com>
10855 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10856 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10857 expression function declaration that is a completion, its
10858 expression causes freezing (AI12-0103).
10860 2017-01-13 Vadim Godunko <godunko@adacore.com>

10875 restriction No_Tasking is in effect.
10876 (Build_Master_Renaming): Do not rename a master when restriction
10877 No_Tasking is in effect.

10886 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
10887 Iterated_Component_Association is not static.
10889 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>

10913 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
10914 Iterated_Component_Present.
10915 * exp_aggr.adb: Use Choice_List throughout, to handle
10916 Iterated_Component_Associations.
10917 (Gen_Loop): Generate proper loop for an
10918 Iterated_Component_Association: loop variable has the identifier
10919 of the original association. Generate a loop even for a single
10920 component choice, in order to make loop parameter visible in
10922 (Flatten): An Iterated_Component_Association is not static.
10924 2017-01-13 Yannick Moy <moy@adacore.com>
10926 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10927 float exponentiation for statically known small negative values
10928 is the reciprocal of the exponentiation for the opposite value
10930 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10931 Ensure that the value of float exponentiation for negative values
10932 is the reciprocal of the exponentiation for the opposite value

10943 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10945 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10946 mode a choice that is a subtype with a static predicate is
10947 replaced by the values it covers. This transformation must not
10948 be performed in ASIS mode, to preserve the source for analysis.
10950 2017-01-13 Justin Squirek <squirek@adacore.com>

10964 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10965 and resolve the discrete choices and the expression of the
10967 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10968 Loop_Actions and Box_Present are attributes of
10969 N_Iterated_Component_Association nodes. Box_Present is always
10970 False in this case.
10971 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10972 has a Discrete_Choices list, as specified in the RM. A
10973 Component_Association for aggregate uses instead a Choices list.
10974 We have to live with this small inconsistency because the new
10975 construct also has a defining identifier, and there is no way
10976 to merge the two node structures.

10988 Analyze_Declarations, to analyze and resolve the expressions of
10989 aspect specifications in the current declarative list, so that
10990 the expressions have proper entity and type info. This is needed
10991 for ASIS when there is no subsequent expansion to generate this
10992 semantic information.
10993 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10994 original expression, to suppress cascaded errors when expression
10995 has been constant-folded.
10996 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10997 ASIS mode, because there is no subsequent expansion to decorate

11002 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11003 New function to detect when a call may be inlined or not in
11005 (Expand_Inlined_Call): Ensure that a temporary
11006 is always created in the cases where a type conversion may be
11007 needed on an input parameter in GNATprove mode, so that GNATprove
11008 sees the check to perform.
11009 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11010 when not applicable due to actual requiring type conversion
11011 with possible check but no temporary value can be copied for
11012 GNATprove to see the check.
