92 N_Extended_Return_Statement by transforming the statements into a
93 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
94 It's too hard for Expand_Cleanup_Actions to operate directly on the
95 N_Extended_Return_Statement, because it has a different structure than
96 the other node kinds that Expand_Cleanup_Actions.
97 * exp_util.adb (Requires_Cleanup_Actions): Add support for
98 N_Extended_Return_Statement. Change "when others => return False;" to
99 "when others => raise ...;" so it's clear what nodes this function

352 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
353 assignment if it is part of an Iterated_Component_Association: the
354 analysis needs to take place once the loop structure is analyzed and
355 the loop parameter made visible, because references to it typically
356 appear in the corresponding expression. This is necessary if the
357 expression is an aggregate, because previous pre-analysis of the

1001 Warnings(Off), which does not work for CodePeer initialization
1002 messages, and given that here the possible read of an unitialized value
1003 depends on a proper use of parameters by the caller.
1004 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
1005 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.

1013 Save_Full_Analysis.
1014 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
1015 and restructure code to defend against previous errors, so that, in
1016 that case, control does not flow to the elsif condition which read an
1017 uninitialized Obj_Decl.
1018 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
1019 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
1020 which seem to be left uninitialized and possibly read in some cases.
1021 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
1022 precisely. This requires to exchange the test for exiting in case of
1023 too many positions and the increment to Position, inside the loop.
1024 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
1025 which cannot be read uninitialized, but the reasons for that are quite
1026 subtle.
1027 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
1028 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
1029 Spec_Id.
1030 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1031 and test for presence of non-null Opnd_Type before testing its scope,
1032 in a test which would read its value uninitialized, and is very rarely
1033 exercized (it depends on the presence of an extension of System).
1034 * sem_spark.ads: Update comment to fix name of main analysis procedure.
1035 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
1036 Test_Result.
1037 * set_targ.adb (FailN): Mark procedure with No_Return.
1038 * stylesw.adb (Save_Style_Check_Options): Delete useless code to
1039 initialize all array Options to white space, as there is already code
1040 doing the same for the remaining positions in Options at the end of the
1041 procedure.
1043 2017-11-09 Eric Botcazou <ebotcazou@adacore.com>
1045 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for
1046 generic instantiations either.
1048 2017-11-09 Piotr Trojanek <trojanek@adacore.com>
1050 * sem_prag.adb (Analyze_Part_Of): Reword error message.
1051 (Get_SPARK_Mode_Type): Do not raise Program_Error in case pragma
1052 SPARK_Mode appears with an illegal mode, treat this as a non-existent
1053 mode.

1057 * sem_ch4.adb (Analyze_Call): Reject a call to a function that returns

1060 another unit.

1064 * sem_ch8.adb (Analyze_Use_Package): Force installation of use_clauses
1065 when processing generic instances.
1067 2017-11-09 Bob Duff <duff@adacore.com>
1069 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1070 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1071 objects can have those special values. Valid_Name_Id could usefully be
1072 used all over the compiler front end, but that's too much trouble for
1073 now. If we did that, we might want to rename:
1074 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1075 For parameters of type Valid_Name_Id, remove some redundant tests,
1076 including the ones found by CodePeer. Use Is_Valid_Name instead of
1077 membership test when appropriate.
1078 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1079 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1080 "in Error_Name_Or_No_Name".
1081 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in
1082 Error_Name_Or_No_Name".
1084 2017-11-09 Arnaud Charlet <charlet@adacore.com>

1087 mode here unless -gnateC is specified.
1088 * switch-c.adb (Scan_Front_End_Switches): Do not suppress warnings with
1089 -gnatC here.

1142 * sem_res.adb (Resolve): If expression is an entity whose type has
1143 implicit dereference, generate reference to it, because no reference is
1144 generated for an overloaded entity during analysis, given that its

2480 forces the analysis of the expression before rewriting it as a body, so
2481 that freeze nodes can appear in the proper scope.

2831 (rather than relocating it) to avoid resolving a potentially malformed
2832 tree when the expression is resolved through an ASIS-specific call to
2833 Resolve_Aspect_Expressions. This manifests itself as a crash on a
2834 function with parameter associations.

2870 call that appears in a classwide precondition and that mentions an

2889 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression for aspect

3674 2017-09-08 Yannick Moy <moy@adacore.com>
3676 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3677 return the entity associated with the call.
3678 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3679 Replace the internal Get_Function_Id with the new
3680 Sem_Aux.Get_Called_Entity.
3681 (Iterate_Call_Parameters): New
3682 procedure to iterate on formals and actuals at the same time.
3683 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3684 Set SPARK_Mode from spec when set, for analysis
3685 of instance. Restore after analysis of instance.
3686 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3687 set, for analysis of body instance. Restored automatically at
3688 the end of the subprogram.
3689 * gnat1drv.adb (Adjust_Global_Switches): Set
3690 Check_Validity_Of_Parameters to False in GNATprove mode.
3691 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3692 set option.
3694 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3696 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3697 (New_Copy_Tree): ...there. Reset the hash tables only if they
3698 were used in the previous invocation.
3699 * s-htable.adb: Fix typo.
3701 2017-09-08 Bob Duff <duff@adacore.com>
3703 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3705 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3707 * sem_aggr.adb: minor style fix.
3709 2017-09-08 Bob Duff <duff@adacore.com>
3711 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3712 no current source file.
3713 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3714 Print something helpful in case N is invalid.
3715 * sprint.ads: Minor comment fix.
3717 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3719 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3720 access types.
3722 2017-09-08 Bob Duff <duff@adacore.com>
3724 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3725 Ada_2020, along the same lines as the other Ada version pragmas.
3727 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3729 * sem_ch12.adb: Minor typo fixes and reformatting.
3731 2017-09-08 Yannick Moy <moy@adacore.com>
3733 * sem_aggr.adb (Resolve_Record_Aggregate):
3734 Rewrite bounds of aggregate subexpressions which may depend on
3735 discriminants of the enclosing aggregate.
3737 2017-09-08 Yannick Moy <moy@adacore.com>
3739 * sem_ch5.adb: Prevent assertion failure on illegal code.
3741 2017-09-08 Yannick Moy <moy@adacore.com>
3743 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3744 calling Renamed_Entity on an entity which cannot be a renaming.
3746 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3748 * exp_aggr.adb: Add with & use clause for Urealp.
3749 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3750 elementary types instead of just discrete types.
3751 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3752 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3753 Be prepared for the FP zero value in the memset case. Add small
3754 guard.
3756 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3758 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3759 of loop.
3761 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3763 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3764 of New_Copy because the latter leaves the syntactic structure of
3765 the tree inconsistent (a child is accessible through two parents)
3766 and prevents proper replication of itypes by subsequent calls
3767 to New_Copy_Tree.
3768 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3769 New_Copy because the latter leaves the syntactic structure of the
3770 tree inconsistent (a child is accessible through two parents)
3771 and prevents proper replication of itypes by subsequent calls
3772 to New_Copy_Tree.
3773 * sem_util.adb (In_Subtree): New routine.
3774 (New_Copy_Tree): Reimplemented.
3775 * sem_util.ads (In_Subtree): New routine.
3776 (New_Copy_Tree): Reimplemented.
3778 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3780 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3781 for aspect Default_Value is a static scalar value, but it does
3782 not freeze the type. Yhis allows for subsequent representation
3783 clauses for the type.
3785 2017-09-08 Javier Miranda <miranda@adacore.com>
3787 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3788 not add entries into the undefined reference table when we are
3789 compiling with errors ignored.
3791 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3793 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3794 check if the instance is within an enclosing instance body. The
3795 formal package was legal in the enclosing generic, and is
3796 legal in the enclosing instantiation. This optimisation may be
3797 applicable elsewhere, and it also removes spurious errors that
3798 may arise with on-the-fly processing of instantiations that
3799 contain Inline_Always subprograms.
3801 2017-09-08 Vincent Celier <celier@adacore.com>
3803 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3805 2017-09-08 Justin Squirek <squirek@adacore.com>
3807 * checks.adb (Insert_Valid_Check): Manually decorate
3808 the generated temporary for range valdity checks.
3810 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3812 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3814 2017-09-08 Justin Squirek <squirek@adacore.com>
3816 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3817 case to handle underscore flags.
3818 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3819 new procedure to handle underscores.
3821 2017-09-08 Javier Miranda <miranda@adacore.com>
3823 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3824 divisions with fixed point results to avoid generating twice
3825 the runtime check on divide by zero.
3826 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3827 not evaluated twice (once for their runtime checks and once for
3828 their regular computation).
3830 2017-09-08 Yannick Moy <moy@adacore.com>
3832 * sem_prag.adb (Analyze_Part_Of): Add missing
3833 return statements after issuing errors. Add detection of
3834 out-of-order item and single concurrent type.

4228 a loop specification that is a subtype indication whose type mark
4229 is a type with a static predicate, inherit predicate function,
4230 used to build case statement for rewritten loop.
4232 2017-09-08 Justin Squirek <squirek@adacore.com>

4346 is necessary and can easily do it); also, do not expect protected
4347 types or protected objects as Context_Id (because no flow-related

4369 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4370 sem_prag.adb to make it available for GNATprove; for concurrent
4371 types replace custom scope climbing with Scope_Same_Or_Within; for
4372 single concurrent objects add scope climbing (with Scope_Within),
4373 which was not there (that's the primary semantic change of this
4374 commit); also, when comparing a single concurrent object with
4375 its corresponding concurrent type rely on equality of types,
4376 not of objects (because that's simpler to code).
4377 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4378 (Analyze_Global_Item): adjust special-casing of references to the
4379 current instance of a concurrent unit in the Global contracts
4380 of task types and single tasks objects; similar for references
4381 in the protected operations and entries of protected types and
4382 single protected objects (in all these cases the current instance
4383 behaves as an implicit parameter and must not be mentioned in
4384 the Global contract).

4456 an enclosing package.

4463 confusion.

4508 R declared in an inner package, and which is thus not a primitive
4509 of the dispatching type of O. In this case O is a new primitive

4532 previous instances. If a package IAP that is an instantiation is
4533 used as an actual in a subsequent instantiation SI in the same
4534 scope, and IAP has a body, IAP must be frozen before SI. If
4535 the generic parent of IAP is itself declared in a previous
4536 instantiation in the same scope, that instantiation must also
4537 be frozen before SI.

4765 initialization of its dispatch tables. (Init_Secondary_Tags):
4766 Adding new formal (Init_Tags_List) and adjusting calls to
4767 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
4768 adjusting also calls to Ada.Tags.Register_Interface_Offset
4769 because the type of one of its formals has been changed.
4770 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4771 modified. Instead of receiving a pointer to an object this
4772 routine receives now a primary tag.
4773 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
4774 additional formal: the tag of the primary dispatch table.
4775 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
4776 * exp_disp.adb (Elab_Flag_Needed): New subprogram.
4777 (Make_Tags): Adding the declaration of the elaboration flag (if needed).
4778 * exp_aggr.adb (Build_Record_Aggr_Code): Adding actual of new
4779 formal in calls to Init_Secondary_Tags.
4781 2017-09-07 Javier Miranda <miranda@adacore.com>
4783 * ghost.adb (Mark_And_Set_Ghost_Instantiation.Check_Ghost_Actuals): New
4784 subprogram.
4785 * sem_prag.adb (Pragma_Ghost): Add missing support for ghost
4786 applied to generic subprograms.
4788 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4790 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
4791 (because it refers to the anonymous concurrent object, not its type);
4792 fix condition for emitting error message about task/protected type,
4794 2017-09-07 Bob Duff <duff@adacore.com>
4796 * binde.adb (Debug_Flag_Old): If both -do and -dp
4797 are specified, behave as if just -do was specified, rather than
4798 using a mixture.
4800 2017-09-07 Nicolas Roche <roche@adacore.com>
4802 * system-vxworks-sparcv9.ads, s-vxwork-m68k.ads, s-vxwork-mips.ads,
4803 system-vxworks-m68k.ads, system-vxworks-mips.ads: Removed.
4805 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4807 * sem_prag.adb (Find_Role): The Global_Seen flag
4808 is now consulted not only for abstract states and variables,
4809 but for all kinds of items.
4810 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4811 generic parameters, because unlike ordinary formal parameters,
4812 generic formals only act as input/ outputs if they are explicitly
4813 mentioned in a Global contract.
4815 2017-09-07 Yannick Moy <moy@adacore.com>
4817 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside
4818 predicate procedure. Check predicate pragma/aspect with Ghost entity.
4819 * exp_ch6.adb, par-ch6.adb, sem_ch13.adb, sem_prag.adb; Minor
4820 reformatting.
4822 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4824 * sem_aggr.adb: Move New_Copy_Tree_And_Dimensions to sem_dim
4825 (code cleanup);
4826 * sem_ch3.adb (Build_Derived_Record_Type):i Call
4827 Copy_Dimensions_Of_Components after creating the copy of the
4828 record declaration.
4829 * sem_dim.ads, sem_dim.adb (Copy_Dimensions_Of_Components): For a
4830 derived recor type, copy the dikensions if any of each component
4831 of the parent record to the corresponding component declarations
4832 of the derived record. These expressions are used among other
4833 things as default values in aggregates with box associations.
4834 * a-dirval-mingw.adb, g-cgi.adb, gnatcmd.adb, lib-xref.adb,
4835 repinfo.adb, sem_attr.adb, sem_ch10.adb, sem_ch6.adb, sem_prag.adb:
4836 Minor reformatting.
4838 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4840 * sem_util.adb: Remove extra space after THEN.
4842 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4844 * sem_ch7.adb (Has_Referencer): For a subprogram renaming,
4845 also mark the renamed subprogram as referenced.
4847 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4849 * par-ch6.adb (P_Subprogram): Improve error message on null
4850 procedure with misplaced aspect specification, which the parser
4851 first attempts to interpret as a malformed expression function.
4853 2017-09-07 Gary Dismukes <dismukes@adacore.com>
4855 * sem_attr.adb (Analyze_Attribute_Old_Result):
4856 Allow attributes Result and Old in the case of an expression
4857 function.
4859 2017-09-07 Justin Squirek <squirek@adacore.com>
4861 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Propagate
4862 Volatile to subcomponents.
4864 2017-09-07 Bob Duff <duff@adacore.com>
4866 * exp_ch7.adb (Find_Last_Init): Check for the
4867 case where a build-in-place function call has been replaced by a
4868 'Reference attribute reference.
4870 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4872 * sem_ch7.adb (Has_Referencer): Recurse on Actions of freeze
4873 nodes.
4875 2017-09-07 Bob Duff <duff@adacore.com>
4877 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration,
4878 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
4879 secondary stack for all functions that return limited tagged
4880 types -- just do it for dispatching calls. Misc cleanup.
4881 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
4882 remove qualifications and type conversions. Fix various bugs
4883 where only a single level of qualification or conversion was
4884 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
4885 instead of "X".
4886 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
4887 cleanup.
4889 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4891 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
4892 do not create actual subtypes that may generate further predicate
4893 functions.
4894 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
4895 of body is a predicate function as well.
4896 (Resolve_Aspect_Expressions, Resolve_Name): For a component
4897 association, only the expression needs resolution, not the name.
4898 (Resolve_Aspect_Expressions, case Predicates): Construct and
4899 analyze the predicate function declaration in the scope of the
4900 type, before making the type and its discriminants visible.
4902 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4904 * gcc-interface/decl.c (warn_on_field_placement): Issue the warning
4905 only if the record type itself comes from source.
4907 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4909 * sem_ch5.adb: Minor reformatting and a typo fix
4911 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4913 * sinput-l.ads: minor remove extra period at the end of comment
4915 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4917 * sem_prag.adb (Add_Item_To_Name_Buffer): remove support for
4918 E_Discriminant.
4919 (Find_Role): remove support for E_Discriminant.
4921 2017-09-06 Javier Miranda <miranda@adacore.com>
4923 * exp_ch6.adb (Expand_Simple_Function_Return):
4924 Add missing implicit type conversion to force displacement of the
4925 "this" pointer.
4927 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
4929 * sem_ch3.adb, sem_aux.adb, sem_res.adb: Minor reformatting.
4931 2017-09-06 Yannick Moy <moy@adacore.com>
4933 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
4934 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
4936 2017-09-06 Bob Duff <duff@adacore.com>
4938 * sem_ch8.adb: Change Assert to be consistent with
4939 other similar ones.
4941 2017-09-06 Bob Duff <duff@adacore.com>
4943 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
4944 requested. Previously, the -do switch meant "run Elab_New and
4945 Elab_Old and use the order chosen by Elab_Old, possibly with
4946 debugging printouts comparing the two orders." Now it means
4947 "do not run Elab_New." This is of use if there are bugs that
4948 cause Elab_New to crash.
4949 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
4950 type conversions.
4951 * ali.ads (Elab_Position): Change type to Nat, to avoid various
4952 type conversions.
4954 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4956 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
4957 reference to SPARK RM.
4959 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4961 * layout.adb: Use SSU short hand consistently throughout the file.
4963 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4965 * freeze.adb (Freeze_Record_Type)
4966 <Sized_Component_Total_Round_RM_Size>: New local variable to
4967 accumulate the rounded RM_Size of components. Update it for
4968 every component whose RM_Size is statically known. Add missing
4969 guard to check that bit packing is really required before issuing
4970 the error about packing. Swap condition for clarity's sake.
4971 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.
4973 2017-09-06 Fedor Rybin <frybin@adacore.com>

4990 project manager sources.
4992 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4994 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4995 entity of a mutable type and the right-hand side is a conditional
4996 expression, resolve the alternatives of the conditional using
4997 the base type of the target entity, because the alternatives
4998 may have distinct subtypes. This is particularly relevant if
4999 the alternatives are aggregates.
5001 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5003 * checks.adb (Apply_Predicate_Check): If the expression is an
5004 aggregate that is the RHS of an assignment, apply the check to
5005 the LHS after the assignment, rather than to the aggregate. This
5006 is more efficient than creating a temporary for the aggregate,
5007 and prevents back-end crashes when the aggregate includes a
5008 dynamic "others' association.
5010 2017-09-06 Yannick Moy <moy@adacore.com>
5012 * sem_ch12.adb (Analyze_Instance_And_Renamings):
5013 Set variable to ignore SPARK_Mode in instance before the analysis
5014 of the generated package declaration.
5016 2017-09-06 Yannick Moy <moy@adacore.com>
5018 * sem_res.adb (Resolve_Call): Do not issue a
5019 message for calls inside expression function, unless body was
5020 seen and is candidate for inlining.
5022 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5024 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
5025 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
5026 body. do not freeze the formals of the generic unit.
5028 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5030 * errout.adb (Error_Msg): Separate the
5031 treatment for warning vs. style messages in inlinings and
5032 instantiations. Prevents blowups on calls to Warn_Insertion for
5033 style messages, which should not be called in that case because
5034 Warning_Msg_Char is not set.
5036 2017-09-06 Justin Squirek <squirek@adacore.com>
5038 * sem_prag.adb (Check_VFA_Conflicts): Created
5039 to group all Volatile_Full_Access checks relating to other
5040 representation pragmas (Mark_Component_Or_Object): Created
5041 to centeralize the flagging of attributes for the record type
5042 component case, a pragma applied individually to a component, and
5043 the object case.
5044 (Process_Atomic_Independent_Shared_Volatile):
5045 Add propagation of certain pragmas to record components and move
5046 evaluation of VFA checks
5048 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5050 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
5051 Do not warn on conditions that are not obeyed for Inline_Always
5052 subprograms, when assertions are not enabled.
5054 2017-09-06 Arnaud Charlet <charlet@adacore.com>
5056 * sem_util.adb (Unique_Entity): For abstract states return their
5057 non-limited view.
5059 2017-09-06 Bob Duff <duff@adacore.com>
5061 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5062 that is a proper body corresponding to a stub, we defer the
5063 adjustment of the sloc until after the correct adjustment has
5064 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5065 the adjustment, because it will be outside the range in (the old,
5066 incorrect) S_Adjustment.
5067 * inline.adb: Use named notation for readability and uniformity.
5068 * sinput-l.adb: Minor improvements to debugging output printed
5069 for Debug_Flag_L.
5070 * sinput-l.ads (Create_Instantiation_Source): Minor comment
5071 correction.

5077 2017-09-06 Sylvain Dailler <dailler@adacore.com>
5079 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
5080 case when Op is of kind N_Qualified_Expression. In this case,
5081 the function is called recursively on the subexpression like in
5082 other cases.
5083 * make.adb: Minor reformatting
5085 2017-09-06 Justin Squirek <squirek@adacore.com>
5087 * einfo.adb (Set_Linker_Section_Pragma): Modify
5088 Set_Linker_Section_Pragma to be consistant with the "getter"
5089 Linker_Section_Pragma.
5090 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5091 checking for container loops so that the index cursor is not
5092 directly changable by the user with the use of E_Loop_Parameter.
5093 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
5094 * sem_warn.adb (Check_References): Revert previous change.
5096 2017-09-06 Bob Duff <duff@adacore.com>

5103 * sem_prag.adb (Analyze_Depends_Global): Reinforce test on object
5104 declarations to only consider valid uses of Global/Depends those on
5105 single concurrent objects.
5107 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5109 * sem_ch13.adb (Check_Record_Representation_Clause): Give an
5110 error as soon as one of the specified components overlaps the
5111 parent field.
5113 2017-09-06 Arnaud Charlet <charlet@adacore.com>
5115 * sem_prag.ads: minor fix typo in comment.
5117 2017-09-06 Justin Squirek <squirek@adacore.com>
5119 * sem_ch5.adb (Analyze_Block_Statement): Verify a block comes
5120 from source before checking source references.
5121 * sem_warn.adb (Check_References): Add check for internal block
5122 before recursing.
5124 2017-09-06 Vincent Celier <celier@adacore.com>

5127 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
5128 gnatname.adb: Remove the Project Manager from the GNAT tools.
5129 * gcc-interface/Makefile.in: ditto.
5131 2017-09-06 Bob Duff <duff@adacore.com>
5133 * sem_util.ads: Minor comment fix.
5135 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5137 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5138 Generate a freeze node for the actual of a formal package, if
5139 the actual is declared in the same unit and has a corresponding
5140 body, to prevent the current instance from being frozen before
5141 the actual is.
5143 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5145 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.

5149 * sem_warn.adb: Minor refactoring.
5151 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5153 * einfo.ads, einfo.adb (Get_Classwwide_Pragma): New utility,
5154 to retrieve the inherited classwide precondition/postcondition
5155 of a subprogram.
5156 * freeze.adb (Freeze_Entity): Use Get_Classwide_Pragma when
5157 freezing a subprogram, to complete the generation of the
5158 corresponding checking code.
5160 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5162 * exp_util.adb (Is_Controlled_Indexing): New routine.
5163 (Is_Displace_Call): Use routine Strip to remove indirections.
5164 (Is_Displacement_Of_Object_Or_Function_Result): Code clean up. Add a
5165 missing case of controlled generalized indexing.
5166 (Is_Source_Object): Use routine Strip to remove indirections.
5167 (Strip): New routine.
5169 2017-09-06 Bob Duff <duff@adacore.com>
5171 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5172 we include the proper header. Otherwise, we just declare the necessary
5173 things from the capabilities library. This is so we can build on
5174 machines without that library, while still enabling that library.
5175 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5176 simply return 0 if the library is not present, or not included
5177 in the link.
5179 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5181 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding
5182 for renamings that involve function calls in prefix form.
5184 2017-09-06 Bob Duff <duff@adacore.com>
5186 * sem_ch3.adb (Analyze_Subtype_Declaration):
5187 Set Has_Delayed_Freeze on a subtype of an incomplete type.
5189 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5191 * par_sco.adb (Extend_Statement_Sequence): When the accept statement
5192 has no parameter specification and no entry index, use the entry name
5193 as the end of the generated SCO statement.
5195 2017-09-06 Steve Baird <baird@adacore.com>
5197 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5198 uses of 'Image and related attributes as having side effects in
5199 order to avoid replicating such uses.
5200 * pprint.ads (Expression_Image) Add new generic formal flag
5201 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5202 (eventually) override the default.
5203 * pprint.adb (Expression_Image) If the new flag is set, then
5204 suppress the ".all" suffix when displaying a dereference whose
5205 prefix is a use of a value-capturing compiler temp of the sort
5206 generated by Expr_Util.Remove_Side_Effects .
5207 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

5219 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode): Use new function.
5220 * sem_util.adb, sem_util.ads (Within_Protected_Type): Renaming
5221 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
5222 so that applies to any entity.
5224 2017-09-06 Yannick Moy <moy@adacore.com>
5226 * sem_ch3.adb (Derived_Type_Declaration): Use
5227 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5229 2017-09-06 Javier Miranda <miranda@adacore.com>
5231 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5232 following ISO-8861.
5234 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5236 * sem_dim.adb (Analyze_Dimension): In an instance, a type
5237 conversion takes its dimensions from the expression, not from
5238 the context type.
5239 (Dimensions_Of_Operand): Ditto.
5241 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5243 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
5244 null procedures when GNAT coverage is used, so that their (empty)
5245 bodies are properly covered.
5247 2017-09-06 Bob Duff <duff@adacore.com>

5601 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5602 side may be derived from that of the left-hand side (as in the

5604 discriminant to be used in the retrieval of the value of the
5605 component must be the entity in the type of the right-hand side.

5634 in a set membership is an overloaded enumeration literal, and
5635 the type of the alternative is resolved from a previous one,
5636 replace the entity of the alternative as well as the type,
5637 to prevent inconsistencies between the entity and the type.

6217 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6219 * sem_ch3.adb (Build_Derived_Record_Type): Fix a few typos and
6220 pastos in part #3 of the head comment.
6222 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6224 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6225 procedure body for a local (sub)type declaration within a
6226 predicate function. Invariant checks do not apply to these, and
6227 the expansion of the procedure will happen in the wrong scope,
6228 leading to misplaced freeze nodes.
6230 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6232 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6233 to analyze generated actions. If the main unit is a body,
6234 the required scope is that of the corresponding unit declaration.
6236 2017-05-02 Arnaud Charlet <charlet@adacore.com>
6238 * einfo.adb (Declaration_Node): flip branches of
6239 an IF statement to avoid repeated negations in its condition;
6240 no change in semantics, only to improve readability.
6242 2017-05-02 Arnaud Charlet <charlet@adacore.com>
6244 * sem_case.adb: Remove extra spaces in parameter declarations.
6246 2017-05-02 Justin Squirek <squirek@adacore.com>
6248 * usage.adb: Replace space with hyphen ("run time" -> "run-time")
6249 in usage line for new -gnatwE switch.
6251 2017-05-02 Claire Dross <dross@adacore.com>
6253 * a-cofuve.ads (Remove): Remove unnecessary
6254 conditions in precondition.
6256 2017-05-02 Vasiliy Fofanov <fofanov@adacore.com>
6258 * a-stream.ads, exp_imgv.adb, sem_ch10.adb,
6259 sem_attr.adb, s-finmas.ads, osint.adb: Minor typo fix.
6261 2017-05-02 Justin Squirek <squirek@adacore.com>
6263 * sem_ch4.adb (Analyze_Case_Expression): Add check for valid
6264 alternative expression.
6265 * sem_res.adb (Resolve_Case_Expression): Ditto.
6267 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6269 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6270 Refine predicate for the case where the primitive operation
6271 is a renaming of equality. An overriding operation that is
6272 a user-defined renaming of predefined equality inherits its
6273 slot from the overridden operation. Otherwise it is treated
6274 as a predefined op and occupies the same predefined slot as
6275 equality. A call to it is transformed into a call to its alias,
6276 which is the predefined equality. A dispatching call thus uses
6277 the proper slot if operation is further inherited and called
6278 with class-wide arguments.
6280 2017-05-02 Justin Squirek <squirek@adacore.com>
6282 * errout.adb (Set_Msg_Text): Add a case to switch the message
6283 type when the character '[' is detected signifying a warning
6284 about a run-time exception.
6285 * opt.ads Add a new Warning_Mode value for new switch
6286 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6287 to handle new warning mode
6288 * usage.adb (Usage): Add usage entry for -gnatwE
6289 * warnsw.adb (Set_Warning_Switch): Add case for the new switch
6291 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6293 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6294 declaration that operates on some fixed point type.
6296 2017-05-02 Justin Squirek <squirek@adacore.com>
6298 * a-crbtgo.adb, s-taasde.adb: Remove unused use-type clauses.
6300 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6302 * sem_ch6.adb (Analyze_Null_Procedure): Revert previous change.
6304 2017-05-02 Justin Squirek <squirek@adacore.com>
6306 * sem_ch4.adb (Analyze_Case_Expression): Add check for valid
6307 expression (Analyze_If_Expression): Add check for valid condition
6308 * sem_eval.adb (Eval_Case_Expression): Add check for error posted
6309 on case-expression
6310 * sem_res.adb (Resolve_If_Expression): Add check for valid
6311 condition and then-expression.
6313 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6315 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6316 statement if the initialization call is a null procedure, as
6317 can happen with a controlled type with no explicit Initialize
6318 procedure, or an array of such.
6319 * exp_ch7.adb (Process_Object_Declaration): For a type with
6320 controlled components that has a trivial Initialize procedure,
6321 insert declaration for finalization counter after object
6322 declaration itself.
6323 (Make_Deep_Array_Body, Build_Initialize_statements): Do not create
6324 finalization block and attendant declarations if component has
6325 a trivial Initialize procedure.
6326 (Make_Init_Call): Do not generate a call if controlled type has
6327 a trivial Initialize procedure.
6329 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6331 * g-forstr.ads (Data): Move Format component last.
6332 * g-forstr.adb ("+"): Adjust for above change.
6333 * g-rewdat.ads (Buffer): Move Buffer, Current, Pattern and Value last.
6334 * g-sechas.ads (Context): Move Key last.
6335 * g-socket.ads (Service_Entry_Type): Move Aliases last.
6336 * s-fileio.adb (Temp_File_Record): Move Name last.
6337 * s-regexp.adb (Regexp_Value): Move Case_Sensitive last.
6338 * xr_tabls.ads (Project_File): Move Src_Dir and Obj_Dir last.
6340 2017-05-02 Jerome Lambourg <lambourg@adacore.com>
6342 * bindusg.adb, bindgen.adb, gnatbind.adb, opt.ads: Remove the -nognarl
6343 switch introduced recently. finally not needed.
6345 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6347 * sem_ch6.adb (Analyze_Null_Procedure): Set the
6348 Corresponding_Body link for a null procedure declaration.
6350 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6352 * atree.h (Flag290): Add missing terminating parenthesis.
6353 * einfo.adb (Is_Class_Wide_Clone): Use Flag290.
6354 (Set_Is_Class_Wide_Clone): Likewise.
6355 * einfo.ads (Is_Class_Wide_Clone): Likewise.
6357 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6359 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6360 parameter Array_Comp to indicate the case of an array object
6361 with null-excluding components.
6362 * checks.adb (Null_Exclusion_Static_Checks):
6363 Call Compile_Time_Constraint_Error instead of
6364 Apply_Compile_Time_Constraint_Error in the component case. Also
6365 call that when Array_Comp is True, with an appropriate warning for
6366 the array component case. Only create an explicit initialization
6367 by null in the case of an object of a null-excluding access type
6368 (and no longer do that in the component case).
6369 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6370 Array_Comp defaulted to False. Pass Empty for the Comp
6371 actual when calling Null_Exclusion_Static_Checks in the case
6372 where Comp_Decl matches Object_Decl, because we don't have a
6373 component in that case. In the case of an object or component
6374 of an array type, pass True for Array_Comp on the recursive call
6375 to Check_Component.
6377 2017-05-02 Bob Duff <duff@adacore.com>
6379 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6380 compute the linux priority from the Ada priority. Call this everywhere
6381 required. In particular, the previous version was not doing this
6382 computation when setting the ceiling priority in various places. It
6383 was just converting to C.int, which results in a ceiling that is off
6384 by 1.
6386 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6388 * sem_ch3.adb: Comment predicate inheritance.
6390 2017-05-02 Tristan Gingold <gingold@adacore.com>
6392 * s-trasym.ads: Add comment.
6394 2017-05-02 Bob Duff <duff@adacore.com>
6396 * sem_elab.adb, sem_elab.ads: Minor comment fixes.
6397 * sem_ch4.adb: Minor reformatting.
6398 * s-taprop-linux.adb, s-taspri-posix.ads: Code refactoring.
6399 * s-taspri-posix-noaltstack.ads: Minor refactoring.
6400 * sinput.ads: Minor typo fix.
6402 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6404 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
6405 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6406 here from exp_ch9, to recognize objects whose creation requires
6407 dynamic allocation, so that the proper warning can be emitted
6408 when restriction No_Implicit_Heap_Allocation is in effect.
6409 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6410 to emit proper warning when an object that requires dynamic
6411 allocation is declared.
6413 2017-05-02 Tristan Gingold <gingold@adacore.com>
6415 * s-trasym.ads, s-trasym.adb (Enable_Cache): New.
6417 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6419 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
6420 visibility rules for equality operators that apply within an
6421 instantiation apply within an inlined body.
6422 * sem_type.adb (Add_One_Interp): ditto.
6424 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6426 * sem_prag.adb (Analyze_Pragma): Forbid pragma Contract_Cases on null
6427 procedures.
6429 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6431 * snames.ads-tmpl
6432 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
6433 Name_No_Tagged_Streams): Move to regular pragmas. Add
6434 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
6435 and Secondary_Stack_Size.
6436 (Pragma_Id): Move Pragma_Assume,
6437 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
6438 Pragma_No_Tagged_Streams to second part.
6440 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6442 * exp_attr.adb: Minor reformatting.
6444 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6446 * sem_ch4.adb (Analyze_Selected_Component): Improve error
6447 detection for illegal references to private components or
6448 operations of a protected type in the body of the type.
6450 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6452 * opt.ads: Add missing GNAT markers in comments.
6453 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
6454 settings of Optimize_Alignment at the end.
6456 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6458 * checks.adb (Apply_Constraint_Check): Do not apply
6459 a discriminant check when the associated type is a constrained
6460 subtype created for an unconstrained nominal type.
6461 * exp_attr.adb: Minor reformatting.
6463 2017-05-02 Bob Duff <duff@adacore.com>
6465 * sem_ch3.adb (OK_For_Limited_Init_In_05): Handle correctly
6466 the N_Raise_Expression case.
6467 * sem_ch6.adb (Check_Limited_Return): Minor: clarify comment,
6468 and add assertions.
6470 2017-05-02 Yannick Moy <moy@adacore.com>
6472 * exp_ch4.adb (Expand_N_Op_Ne): Do not bump parenthese level and
6473 optimize length comparison in GNATprove mode.
6474 * exp_spark.adb (Expand_SPARK_Op_Ne): New function to rewrite
6475 operator /= into negation of operator = when needed.
6476 (Expand_SPARK): Call new
6477 function to expand operator /=.
6479 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6481 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6482 Simplify the expression for a fixed-fixed division to remove
6483 divisions by constants whenever possible, as an optimization
6484 for restricted targets.
6486 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6488 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6490 2017-05-02 Bob Duff <duff@adacore.com>
6492 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6493 to find primitive ops, instead of using an Identifier that will
6494 later be looked up. This is necessary because these ops are not
6495 necessarily visible at all places where we need to call them.
6496 * exp_util.ads: Minor comment fix.
6498 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6500 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6501 references are fully conformant if they are both expansions
6502 of the discriminant of a protected type, within one of the
6503 protected operations. One occurrence may be expanded into a
6504 constant declaration while the other is an input parameter to
6505 the corresponding generated subprogram.
6507 2017-05-02 Justin Squirek <squirek@adacore.com>
6509 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6510 recursivly searching composite-types for null-excluding access
6511 types and verifying them.
6512 (Analyze_Object_Declaration): Add a
6513 call to Check_Null_Excluding_Components for static verification
6514 of non-initialized objects.
6515 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6516 a parameter for a composite-type's component and an extra case
6517 for printing component information.
6519 2017-05-02 Yannick Moy <moy@adacore.com>
6521 * sem_ch10.adb (Analyze_Subunit): Take
6522 configuration pragma into account when restoring appropriate
6523 pragma for analysis of subunit.
6525 2017-05-02 Justin Squirek <squirek@adacore.com>
6527 * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
6528 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
6529 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
6530 clauses from the runtime.
6532 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6534 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
6535 array components specially.
6537 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6539 * sem_ch8.adb (Premature_Usage): If the premature usage of
6540 an entity is as the expression in its own object decaration,
6541 rewrite the reference as Any_Id to prevent cascaded errors or
6542 compiler loops when such an entity is used in an address clause.
6544 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6546 * gcc-interface/decl.c (components_to_record): Add missing guard.
6548 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6550 * gcc-interface/decl.c (components_to_record): Add more comments.
6551 Put back pending fields onto the regular list if the misalignment
6552 happens to cancel itself.
6554 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6556 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6557 controlling actual in a prefixed call, preserve the original node
6558 information if the prefix itself has been rewritten, for ASIS use.
6560 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6562 * exp_ch6.adb (Insert_Post_Call_Actions):
6563 Code clean up. Insert the post-call actions after an enclosing
6564 procedure call when N denotes a function call and appears as an
6565 actual parameter in the procedure call.
6567 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6569 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6570 for the component, also reject the attribute if the component
6571 doesn't end on a byte boundary and its scalar storage order is
6572 different from that of the enclosing record type.
6574 2017-04-28 Javier Miranda <miranda@adacore.com>
6576 * atree.ads (Info_Messages): Removed.
6577 (Warning_Info_Messages): New counter.
6578 (Report_Info_Messages): New counter.
6579 * err_vars.ads Update documentation.
6580 * errout.adb (Delete_Warning_And_Continuations): Update
6581 Info_Message occurrences.

6590 (Initialize): Update Info_Message occurrences.
6591 * erroutc.adb (Delete_Msg): Update Info_Message occurrences.
6592 (Compilation_Errors): Update Info_Message_Occurences.
6594 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6596 * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.

6606 2017-04-28 Bob Duff <duff@adacore.com>
6608 * sem_util.ads, sem_util.adb (Might_Raise): New function
6609 that replaces Is_Exception_Safe, but has the opposite
6610 sense. Is_Exception_Safe was missing various cases -- calls inside
6611 a pragma Debug, calls inside an 'if' or assignment statement,
6612 etc. Might_Raise now walks the entire subtree looking for things
6613 that can raise.
6614 * exp_ch9.adb (Is_Exception_Safe): Remove.
6615 (Build_Protected_Subprogram_Body): Replace call to
6616 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6617 constants where possible).
6618 * exp_ch7.adb: Rename Is_Protected_Body -->
6619 Is_Protected_Subp_Body. A protected_body is something different
6620 in the grammar.
6622 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6624 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.

6635 (Analyze_Iterator_Specification): Initialize Bas variable.
6636 * sem_ch9.adb (Allows_Lock_Free_Implementation): Initialize
6637 Error_Count (Satisfies_Lock_Free_Requirements): Likewise.
6638 (Analyze_Accept_Statement): Initialize Task_Nam.
6640 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6642 * checks.adb (Install_Primitive_Elaboration_Check):
6643 Do not generate an elaboration check if all checks have been
6644 suppressed.
6646 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6648 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6649 Interrupt_Handler and Attach_Handler): Generate reference
6650 to protected operation to prevent spurious warnings about
6651 unreferenced entities. Previous scheme failed with style checks
6652 enabled.
6654 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6656 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6657 that follows an expression function must not be relocated to
6658 the generated body, because it applies to the code that follows.
6660 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6662 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6663 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6664 code that might violate the more stringent checking for 'Access
6665 introduced in Ada 2005.
6667 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6669 * a-cforse.adb: minor style fix in comment.
6671 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6673 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6674 initialize Block_Decls variable.
6675 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6676 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
6677 * exp_disp.adb (Expand_Interface_Actuals): Initialize
6678 Formal_DDT and Actual_DDT variables.

6684 (Build_To_Any_Function): Initialize Cstr_Formal.
6685 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6687 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6689 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6690 node between access types, freeze the designated type as well,
6691 so that dispatch table pointers are created in the proper scope,
6692 and not in the constructed body of the expression function.
6694 2017-04-28 Bob Duff <duff@adacore.com>
6696 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6697 value makes large compilations faster, but small compilations slower.
6699 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6701 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6703 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6705 * erroutc.adb (Compilation_Errors): Do not consider info messages
6706 as suitable warnings when warnings must be treated as errors.
6707 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6708 internally-generated packages when outputting completion
6709 information.
6710 * errout.adb (Output_Messages): Do not consider info messages as
6711 suitable warnings when warnings must be treated as errors.
6712 * errutil.adb (Finalize): Do not consider info messages as
6713 suitable warnings when warnings must be treated as errors.
6715 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6717 * warnsw.ads: Minor fix for incorrect wording in comment.
6719 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6721 * sem_res.adb (In_Instance_Code): New predicate in
6722 Valid_Conversion, to determine whether a type conversion appears
6723 as (or within) an actual for a formal object. Type conversions
6724 in instances are not rechecked in Valid_Conversion because
6725 visibility changes between generic location andi instance may
6726 lead to spurious errors, but conversions within an actual must be
6727 fully checked, and they are not fully resolved when pre-analyzing
6728 the actuals.
6730 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6732 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6733 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6734 of the relocated node will have mangled Parent pointers.
6735 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6736 tables used in conjunction with entity and itype replication.
6737 (Visit_Entity): Rewrite the restriction on which entities
6738 require duplication. The restriction now includes all types.

6772 (Restore_Warnings): Likewise.
6773 (Save_Warnings): Likewise.
6774 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.

6778 (warn_on_field_placement): Likewise.
6779 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6780 parameters. Rename local variables and adjust recursive call.
6781 Rework final scan of the field list and implement warnings on the
6782 problematic placement of specific sorts of fields.
6784 2017-04-27 Bob Duff <duff@adacore.com>

6791 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6792 For efficiency, cache results of Is_Internal_File_Name and
6793 Is_Predefined_File_Name in the Units table. This avoids a lot
6794 of repeated text processing.
6796 2017-04-27 Emmanuel Briot <briot@adacore.com>
6798 * g-comlin.adb (Sort_Sections): remove useless test.
6800 2017-04-27 Claire Dross <dross@adacore.com>
6802 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6803 allow the use of regular equality over elements in contracts.
6804 (Formal_Model): Ghost package containing model functions that are
6805 used in subprogram contracts.
6806 (Current_To_Last): Removed, model functions should be used instead.
6807 (First_To_Previous): Removed, model functions should be used instead.
6808 (Strict_Equal): Removed, model functions should be used instead.
6809 (No_Overlap): Removed, model functions should be used instead.
6810 (Equivalent_Keys): Functions over cursors are removed. They were
6811 awkward with explicit container parameters.
6812 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6813 allow the use of regular equality over elements in contracts.
6814 (Formal_Model): Ghost package containing model functions that

6821 2017-04-27 Yannick Moy <moy@adacore.com>
6823 * gnat1drv.adb: Code cleanup.
6825 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6827 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6828 attribute reference in a post- condition is the subprogram to
6829 which the condition applies. If the condition is inherited
6830 by a type extension, the prefix becomes a reference to the
6831 inherited operation, but there is no need to create a wrapper
6832 for this operation, because 'Result is expanded independently
6833 when elaborating the postconditions.
6835 2017-04-27 Bob Duff <duff@adacore.com>
6837 * sinput.adb: Minor code cleanup.
6838 * namet.adb (Append): Create faster versions of
6839 Append(String) and Append(Name_Id) by using slice assignment
6840 instead of loops.
6841 * sem_util.adb (In_Instance): Speed this up by removing
6842 unnecessary tests; Is_Generic_Instance is defined for all
6843 entities.
6844 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6845 Remove unused function.
6846 * alloc.ads (Nodes_Initial): Use a much larger value, because
6847 the compiler was spending a lot of time copying the nodes table
6848 when it grows. This number was chosen in 1996, so is rather out
6849 of date with current memory sizes. Anyway, it's virtual memory.
6850 Get rid of Orig_Nodes_...; use Node_... instead.
6851 * atree.adb (Lock): Do not release the Nodes tables; it's a
6852 waste of time.
6853 Orig_Nodes_ ==> Nodes_
6854 * nlists.adb: Orig_Nodes_ ==> Nodes_
6855 * g-table.adb: Remove unused "with" clause.
6856 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6857 not be used by clients.
6858 * g-dyntab.adb (Last_Allocated): New function
6859 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
6861 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

6875 qualified expressions, type conversions, and unchecked type
6876 conversions.
6877 * g-comlin.adb (Is_In_Config): Merge the processing for No_Space
6878 and Optional.
6879 * par-ch3.adb (P_Declarative_Items): Merge the processing for
6880 tokens function, not, overriding, and procedure.
6881 * sem_ch6.adb (Fully_Conformant_Expressions): Merge the processing
6882 for qualified expressions, type conversions, and unchecked
6883 type conversions.
6884 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
6885 processing for Ada 83 and instances.
6886 (Object_Access_Level): Merge the processing for indexed components
6887 and selected components.
6888 * uname.adb (Add_Node_Name): Merge the processing for stubs.

6892 * checks.adb (Install_Primitive_Elaboration_Check):
6893 Do not generate the check when restriction No_Elaboration_Code
6894 is in effect.
6896 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6898 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
6899 of Expand_Dispatching_Call. If the denoted subprogram has a
6900 class-wide precondition, this is the only precondition that
6901 applies to the call, rather that the class-wide preconditions
6902 that may apply to the body that is executed. (This is specified
6903 in AI12-0195).
6905 2017-04-27 Yannick Moy <moy@adacore.com>
6907 * gnat1drv.adb (Adjust_Global_Switches): Issue
6908 a warning in GNATprove mode if the runtime library does not
6909 support IEEE-754 floats.
6911 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6913 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6914 is itself inherited it does not carry any contract information,
6915 so examine its parent operation which is its Alias.
6917 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6919 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6920 prefix can be an object reference in which case Obj'Image (X)
6921 can only be interpreted as an indexing of the parameterless
6922 version of the attribute.
6923 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6924 an indexing or a slice operation if the attribute does not require
6925 parameters. In Ada2012 'Image also belongs in this category,
6926 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6928 2017-04-27 Yannick Moy <moy@adacore.com>
6930 * exp_ch4.adb: Minor reformatting.
6931 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
6932 disable the CodePeer and C generation modes. Similar to the
6933 opposite actions done in CodePeer mode.

6953 elaboration check.
6955 2017-04-27 Bob Duff <duff@adacore.com>
6957 * g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.
6958 If the table grows and then shrinks back to empty, we won't necessarily
6959 point back to the empty array. Code cleanups.
6960 * sinput.ads: Add 'Base to Size clause to match the declared
6961 component subtypes.
6963 2017-04-27 Claire Dross <dross@adacore.com>

6986 of equivalence on functional maps.
6987 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model.P) Disable handling
6988 of equivalence on functional maps.

6992 * exp_ch9.adb (Expand_Entry_Barrier): Code
6993 cleanup. Do not perform the optimization which removes the
6994 declarations of the discriminant and component renamings when

7008 null pointer dereference.
7010 2017-04-27 Bob Duff <duff@adacore.com>
7012 * g-dyntab.ads, g-dyntab.adb: Default for Table_Low_Bound.
7013 Rename Empty --> Empty_Table_Ptr, and don't duplicate code for it.
7014 Free renames Init, since they do the same thing.
7015 * g-table.ads: Default for Table_Low_Bound.
7016 * table.ads: Default for Table_Low_Bound, Table_Initial, and
7017 Table_Increment.

7059 * g-dyntab.ads, g-dyntab.adb: Misc cleanup. Rename
7060 Table_Count_Type --> Table_Last_Type, because the name
7061 was confusing (a "count" usually starts at zero). Add
7062 functionality supported or needed by other tables packages
7063 (Move, Release_Threshold).
7064 * g-table.ads, g-table.adb: This is now just a thin wrapper
7065 around g-dyntab.ads/g-dyntab.adb. Add functionality supported
7066 or needed by other tables packages (Save, Restore).
7067 * table.ads, table.adb: This is now just a thin wrapper around
7068 * g-table.ads/g-table.adb.
7069 * namet.h, scos.h, uintp.h: These files are reaching into the
7070 private data of some instances of g-table, whose names changed,
7071 so the above change requires some adjustment here. It now uses
7072 public interfaces.
7074 2017-04-27 Bob Duff <duff@adacore.com>
7076 * namet.adb, namet.ads: Minor: remove unused procedures.

7100 (Strict_Equal): Removed, model functions should be used instead.
7101 (No_Overlap): Removed, model functions should be used instead.

7116 * freeze.adb (Build_Inherited_Condition_Pragmas): New procedure,
7117 subsidiary of Check_Inherited_Conditions, to build pragmas for an
7118 operation whose ancestor has classwide pre/postconditions. This
7119 is used both to check the legality of the inheritance in Ada
7120 and in SPARK, and to determine whether a wrapper is needed for
7121 an inherited operation.
7122 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity):
7123 Improve placement of error message for inherited classwide
7124 conditions that become illegal on type derivation.

7146 * exp_ch9.adb (Expand_N_Asynchronous_Select): Initialize the Cancel
7147 flag when it is declared in order to avoid confusing CodePeer about
7148 the possibility of an uninitialized variable read.
7150 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7152 * sem_dim.adb (Analyze_Dimension_Object_Declaration): There is
7153 no dimensionality error if the subtype of the expression is
7154 identical to the nominal subtype in the declaration, even though
7155 the expression itself may have been constant-folded and lack a
7156 dimension vector.
7157 * sem_dim.ads: Add comments on setting of dimension vectors and
7158 its interaction with node rewritings and side-effect removal.

7270 Build body of subprogram that has a class-wide condition that
7271 contains calls to other primitives.
7272 (Build_Class_Wide_Clone_Call); Build a call to the common
7273 class-wide clone of a subprogram with classwide conditions. The
7274 body of the subprogram becomes a wrapper for a call to the
7275 clone. The inherited operation becomes a similar wrapper to which
7276 modified conditions apply, and the call to the clone includes
7277 the proper conversion in a call the parent operation.
7278 (Build_Class_Wide_Clone_Decl (Spec_Id : Entity_Id): For a
7279 subprogram that has a classwide condition that contains calls to
7280 other primitives, build an internal subprogram that is invoked
7281 through a type-specific wrapper for all inherited subprograms
7282 that may have a modified condition.

7284 condition, create entity for corresponding clone, to be invoked
7285 through wrapper subprograns.

7287 message about placement if pragma isi internally generated.
7288 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): If subprogram has
7289 a classwide clone, build body of clone as copy of original body,
7290 and rewrite original body as a wrapper as a wrapper for a call to
7291 the clone, so that it incorporates the original pre/postconditions
7292 of the subprogram.
7293 * freeze.adb (Check_Inherited_Conditions): For an inherited
7294 subprogram that inherits a classwide condition, build spec and
7295 body of corresponding wrapper so that call to inherited operation
7296 gets the modified conditions.
7297 * contracts.adb (Analyze_Contracts): If analysis of classwide
7298 condition has created a clone for a primitive operation, analyze
7299 declaration of clone.

7324 * exp_util.ads, exp_util.adb (Evaluate_Name): Force evaluation
7325 of expression being qualified, when not an object name, or else
7326 evaluate the underlying name.

7344 a use-visible entity is defined within a nested scope of an
7345 instance when giving priority to entities which were visible in
7346 the original generic.

7357 Propagate Has_Pragma_Unreferenced_Objects to the built subtype.
7359 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7361 * sem_prag.adb (Analyze_Global_Item):
7362 Do not consider discriminants because they are not "entire
7363 objects". Remove the discriminant-related checks because they are
7364 obsolete.
7365 (Analyze_Input_Output): Do not consider discriminants
7366 because they are not "entire objects".
7368 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7370 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Do not
7371 perform check if the current scope does not come from source,
7372 as is the case for a rewritten task body, because check has
7373 been performed already, and may not be doable because of changed
7374 visibility.
7376 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7378 * a-cofuse.adb, a-cfdlli.adb, a-cofuse.ads, a-cfdlli.ads, a-cofuve.adb,

7384 * sem_ch4.adb (Analyze_Call): If the return type of a function
7385 is incomplete in an context in which the full view is available,
7386 replace the type of the call by the full view, to prevent spurious
7387 type errors.
7388 * exp_disp.adb (Check_Premature_Freezing): Disable check on an
7389 abstract subprogram so that compiler does not reject a parameter
7390 of a primitive operation of a tagged type being frozen, when
7391 the untagged type of that parameter cannot be frozen.

7428 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
7429 modifications in functional containers.
7430 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7431 to improve readablity. Subprograms are separated between basic
7432 operations, constructors and properties. Universally quantified
7433 formulas in contracts are factorized in independant functions
7434 with a name and a comment. Names of parameters are improved.
7436 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7438 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7440 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7442 * sem_res.adb (Resolve_Type_Conversion): Do not
7443 install a predicate check here since this is already done during
7444 the expansion phase. Verify whether the operand satisfies the
7445 static predicate (if any) of the target type.
7446 * sem_ch3.adb (Analyze_Object_Declaration): Do
7447 not install a predicate check if the object is initialized by
7448 means of a type conversion because the conversion is subjected
7449 to the same check.
7451 2017-04-27 Tristan Gingold <gingold@adacore.com>
7453 * raise.c (__gnat_builtin_longjmp): Remove.
7454 (__gnat_bracktrace):
7455 Add a dummy definition for the compiler (__gnat_eh_personality,

7471 a-except.ad[sb].
7472 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
7473 in gnat1 and gnatbind.
7474 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,

7487 formulas in contracts are factorized in independant functions
7488 with a name and a comment. Names of parameters are improved.
7490 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7492 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7494 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7496 * sem_res.adb (Resolve_Type_Conversion): Do not

7498 the expansion phase. Verify whether the operand satisfies the
7499 static predicate (if any) of the target type.
7500 * sem_ch3.adb (Analyze_Object_Declaration): Do
7501 not install a predicate check if the object is initialized by

7520 Ada95.
7522 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7524 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7525 the loop which detects potential enclosing transient scopes. The
7526 loop now terminates much earlier as transient scopes are bounded
7527 by packages and subprograms.
7529 2017-04-27 Claire Dross <dross@adacore.com>
7531 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7532 allow the use of regular equality over elements in contracts.
7533 (Cursor): Type is now public so that it can be used in
7534 model functions.
7535 (Formal_Model): Ghost package containing
7536 model functions that are used in subprogram contracts.
7537 (Current_To_Last): Removed, model functions should be used
7538 instead.
7539 (First_To_Previous): Removed, model functions should
7540 be used instead.

7562 Default_Initial_Condition procedure of a type under the SPARK
7563 elaboration checks umbrella.
7565 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7567 * sem.adb (Analyze): Diagnose an illegal iterated component
7568 association.

7575 getcwd fails.
7576 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7577 exception if getcwd failed.
7579 2017-04-27 Yannick Moy <moy@adacore.com>

7582 entities with special prefix.
7584 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7586 * debug.adb Change the documentation of switch -gnatd.s.
7587 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7588 to manage the secondary stack when an enclosing scope already
7589 performs this functionality (aka relaxed management). Switch
7590 -gnatd.s may be used to force strict management in which case
7591 the block will manage the secondary stack unconditionally. Add
7592 a guard to stop the traversal when encountering a package or a
7593 subprogram scope.
7595 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7597 * sem_res.adb (Resolve_Call): Refine further the handling of
7598 limited views of return types in function calls. If the function
7599 that returns a limited view appears in the current unit,
7600 we do not replace its type by the non-limited view because
7601 this transformation is performed int the back-end. However,
7602 the type of the call itself must be the non-limited view, to
7603 prevent spurious resolution errors.
7605 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7607 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7608 Removed, proposed implementation using generics for class-wide
7609 preconditions proved impractical.
7610 (Class_Wide_Clone): New attribute of subprogram. Designates
7611 subprogram created for primitive operations with class-wide
7612 pre/postconditions that contain calls to other primitives. The
7613 clone holds the body of the original primitive, but the
7614 pre/postonditions do not apply to it. The original body is
7615 rewritten as a wrapper for a call to the clone.
7616 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7617 the flag is set, no code for the corresponding pre/postconditions
7618 is inserted into its body.
7620 2017-04-27 Bob Duff <duff@adacore.com>
7622 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

7633 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
7634 (Remove): New function that removes an element from a set.
7635 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
7636 (Remove): New function that removes an element from a sequence.
7637 (Insert): New function that adds anywhere in a sequence.

7649 * lib-xref.adb (Generate_Reference): The use
7650 of attribute 'Result is not considered a violation of pragma
7651 Unreferenced.
7653 2017-04-27 Justin Squirek <squirek@adacore.com>
7655 * cstand.adb (Create_Standard): Correctly set

7666 private child of Ada.Containers used to implement all functional
7667 containers.

7805 from spec to body, because it is not used outside the body.
7806 Move Set_Source_File_Index_Table into the private part, because
7807 it is used only in the body and in children. Use trickery to
7808 modify the dope in the generic instantiation case. It's ugly,

7827 on the target type.
7828 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7829 Remove variants that include a Supress parameter. These routines

7882 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7883 the Internal_Source buffer. This removes the incorrect call to "="
7884 the customer noticed.
7885 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7886 eventually need to eliminate them altogether. Or else get rid
7887 of zero-origin addressing.

8166 * exp_attr.adb (Expand_Attribute_Reference, case 'Read):
8167 If the type is an unchecked_union, replace the attribute with
8168 a Raise_Program_Error (rather than inserting such before the
8169 attribute reference) to handle properly the case where we are
8170 processing a component of a larger record, and we need to prevent
8171 further expansion for the unchecked union.
8172 (Expand_Attribute_Reference, case 'Write): If the type is
8173 an unchecked_union, check whether enclosing scope is a Write
8174 subprogram. Replace attribute with a Raise_Program_Error if the
8175 discriminants of the unchecked_union type have not default values
8176 because such a use is erroneous..

8393 private type for interfaces, and move the processing of types
8394 until after the processing of invariants for the full view.
8395 (Build_Invariant_Procedure_Declaration): Remove condition
8396 to return if an interface type is encountered and add
8397 condition to convert the formal parameter to its class-wide
8398 counterpart if Work_Typ is abstract.

8421 (10-15): if derived type T with progenitors is abstract,
8422 and primitive P of this type inherits non-trivial classwide
8423 preconditions from both a parent operation and from an interface
8424 operation, then the inherited operation is abstract if the parent
8425 operation is not null.
8426 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8427 with Covered_Interface_Op to yield the actual interface operation
8428 that is implemented by a given inherited operation.

8458 include an implicit dereference.
8459 * sem_type.adb (Disambiguate): If two interpretations are access
8460 attribute types with the same designated type keep either of
8461 them and do not report an ambiguity. A true ambiguity will be
8462 reported elsewhere.
8464 2017-04-25 Bob Duff <duff@adacore.com>
8466 * a-numeri.ads: Change the encoding of Greek letter Pi from
8467 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8468 to indicate the encoding. We considered using a byte order mark
8469 (BOM), but that causes various trouble (misc software eats the
8470 BOM, if you have a patch with a BOM, then it's not at the start
8471 of the patch, so it's not a BOM, the BOM affects with-ing files,
8472 etc.).

8641 and add associated guards.
8643 2017-04-25 Olivier Hainque <hainque@adacore.com>
8645 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8646 specs without elaboration code that have an elaboration counter
8647 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8648 * sem_ch10.adb (Analyze_Compilation_Unit):
8649 Set_Elaboration_Entity_Required when requested to preserve
8650 control flow, to ensure the unit elaboration is materialized at
8651 bind time, resulting in the inclusion of the unit object file
8652 in the executable closure at link time.
8654 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8656 * exp_dbug.adb: In Debug_Renaming_Declaration,
8657 when dealing with indexed component, accept to produce a renaming
8658 symbol when the index is an IN parameter or when it is a name
8659 defined in an outer scope.
8661 2017-04-25 Yannick Moy <moy@adacore.com>
8663 * errout.adb (Error_Msg): Adapt continuation
8664 message in instantiations and inlined bodies for info messages.
8666 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8668 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8669 Use direct 4-character slice comparisons.
8670 (Has_Prefix): Add
8671 pragma Inline. (Has_Suffix): Delete.
8672 (Is_Internal_File_Name):
8673 Test Is_Predefined_File_Name first.
8674 (Is_Predefined_File_Name):
8675 Use direct slice comparisons as much as possible and limit all
8676 comparisons to at most 8 characters.
8678 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8680 * checks.adb (Insert_Valid_Check): Code cleanup.
8681 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8682 (Expand_Actuals): Generate proper copy-back for a validation
8683 variable when it acts as the argument of a type conversion.
8684 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8685 predicate to operate on type qualifications.
8687 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8689 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8690 Minor reformatting.
8692 2017-04-25 Bob Duff <duff@adacore.com>
8694 * sem_prag.adb (No_Return): Give an error if the pragma applies
8695 to a body. Specialize the error for the specless body case,
8696 as is done for (e.g.) pragma Convention.
8697 * debug.adb: Add switch -gnatd.J to disable the above legality
8698 checks. This is mainly for use in our test suite, to avoid
8699 rewriting a lot of illegal (but working) code. It might also
8700 be useful to customers. Under this switch, if a pragma No_Return
8701 applies to a body, and the procedure raises an exception (as it
8702 should), the pragma has no effect. If the procedure does return,
8703 execution is erroneous.
8705 2017-04-25 Bob Duff <duff@adacore.com>
8707 * exp_ch6.adb (Expand_Actuals): This is the
8708 root of the problem. It took N as an 'in out' parameter, and in
8709 some cases, rewrote N, but then set N to Original_Node(N). So
8710 the node returned in N had no Parent. The caller continued
8711 processing of this orphaned node. In some cases that caused a
8712 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8713 and trips over the Empty Parent). The solution is to make N an
8714 'in' parameter. Instead of rewriting it, return the list of
8715 post-call actions, so the caller can do the rewriting later,
8716 after N has been fully processed.
8717 (Expand_Call_Helper): Move most of Expand_Call here. It has
8718 too many premature 'return' statements, and we want to do the
8719 rewriting on return.
8720 (Insert_Post_Call_Actions): New procedure to insert the post-call
8721 actions in the appropriate place. In the problematic case,
8722 that involves rewriting N as an Expression_With_Actions.
8723 (Expand_Call): Call the new procedures Expand_Call_Helper and
8724 Insert_Post_Call_Actions.
8726 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8728 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8729 properly type derived from generic formal types, to handle
8730 properly modified version of ACATS 4.1B B611017.
8732 2017-04-25 Javier Miranda <miranda@adacore.com>
8734 * exp_unst.adb (Subp_Index): Adding missing
8735 support for renamings and functions that return a constrained
8736 array type (i.e. functions for which the frontend built a
8737 procedure with an extra out parameter).
8739 2017-04-25 Pascal Obry <obry@adacore.com>
8741 * s-string.adb: Minor code clean-up.
8743 2017-04-25 Bob Duff <duff@adacore.com>
8745 * s-os_lib.ads, s-os_lib.adb (Non_Blocking_Wait_Process): New
8746 procedure.
8747 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
8748 function for Non_Blocking_Wait_Process.
8750 2017-04-25 Bob Duff <duff@adacore.com>
8752 * prep.adb (Preprocess): Remove incorrect
8753 Assert. Current character can be ASCII.CR.
8755 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8757 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8758 convention Stdcall, which has a number of exceptions. Convention
8759 is legal on a component declaration whose type is an anonymous
8760 access to subprogram.
8762 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8764 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8765 (Try_One_Prefix_Interpretation): Use the base type when dealing
8766 with a subtype created for purposes of constraining a private
8767 type with discriminants.
8769 2017-04-25 Javier Miranda <miranda@adacore.com>
8771 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
8772 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
8773 dispatching primitives (Restore_Warnings): Restore warning on
8774 late dispatching primitives (Save_Warnings): Save warning on late
8775 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8776 to enable/disable this warning.
8777 (WA_Warnings): Set warning on late dispatching primitives.
8778 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8779 that its parent type has a private extension.
8780 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8781 New subprogram.
8782 * usage.adb: Document -gnatw.j and -gnatw.J.
8784 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8786 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8787 reformatting.
8789 2017-04-25 Bob Duff <duff@adacore.com>
8791 * binde.adb (Validate): Do not pass dynamic strings
8792 to pragma Assert, because older compilers do not support that.
8794 2017-04-25 Bob Duff <duff@adacore.com>
8796 * s-fileio.adb (Close): When a temp file is
8797 closed, delete it and clean up its Temp_File_Record immediately,
8798 rather than waiting until later.
8799 (Temp_File_Record): Add File
8800 component, so Close can know which Temp_File_Record corresponds
8801 to the file being closed.
8802 (Delete): Don't delete temp files,
8803 because they are deleted by Close.
8804 (Open): Set the File component
8805 of Temp_File_Record. This requires moving the creation of the
8806 Temp_File_Record to the end, after the AFCB has been created.
8808 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8810 * checks.adb (Insert_Valid_Check): Do not generate
8811 a validity check when inside a generic.
8813 2017-04-25 Yannick Moy <moy@adacore.com>
8815 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
8817 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8819 * snames.ads-tmpl (Snames): More names for detecting predefined
8820 potentially blocking subprograms.
8822 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8824 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
8825 concerning inheritance of class-wide preconditions do not apply
8826 to postconditions.
8828 2017-04-25 Bob Duff <duff@adacore.com>
8830 * s-ficobl.ads: Minor comment fix.
8832 2017-04-25 Yannick Moy <moy@adacore.com>
8834 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8835 conversions from float to integer in GNATprove mode.
8836 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8837 to call Apply_Type_Conversion_Checks, so that range checks
8838 are properly positioned when needed on conversions, including
8839 when converting from float to integer. (Determine_Range): In
8840 GNATprove mode, take into account the possibility of conversion
8841 from float to integer.
8842 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8843 check on conversions from fixed-point to integer, not anymore
8844 on conversions from floating-point to integer, when in GNATprove
8845 mode.
8847 2017-04-25 Yannick Moy <moy@adacore.com>
8849 * checks.adb (Determine_Range_R): Special case type conversions
8850 from integer to float in order to get bounds in that case too.
8851 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8852 mode, for computations involved in interval checking.
8854 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8856 * checks.adb (Insert_Valid_Check): Partially reimplement validity
8857 checks.
8858 * einfo.adb Node36 is now used as Validated_Object.
8859 (Validated_Object): New routine.
8860 (Set_Validated_Object): New routine.
8861 (Write_Field36_Name): Add an entry for Validated_Object.
8862 * einfo.ads Add new attribute Validated_Object along with
8863 usage in entities.
8864 (Validated_Object): New routine along with pragma Inline.
8865 (Set_Validated_Object): New routine along with pragma Inline.
8866 * exp_attr.adb (Make_Range_Test): Add processing for validation
8867 variables to avoid extra reads and copies of the prefix.
8868 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8869 variables in order to reflect any changes done in the variable
8870 back into the original object.
8871 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8872 * sem_util.ads (Is_Validation_Variable_Reference): New routine.
8874 2017-04-25 Steve Baird <baird@adacore.com>
8876 * exp_ch7.adb (Build_Array_Deep_Procs,
8877 Build_Record_Deep_Procs, Make_Finalize_Address_Body): Don't
8878 generate Finalize_Address routines for CodePeer.
8880 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8882 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8883 Analyze_Pre_Post_Condition, to implement the legality checks
8884 mandated by AI12-0131: Pre'Class shall not be specified for an
8885 overriding primitive subprogram of a tagged type T unless the
8886 Pre'Class aspect is specified for the corresponding primitive
8887 subprogram of some ancestor of T.
8889 2017-04-25 Bob Duff <duff@adacore.com>
8891 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8892 is redundant, set its Used_Operations to empty. This is only
8893 necessary for use clauses that appear in the parent of a generic
8894 child unit, because those use clauses get reanalyzed when we
8895 instantiate the generic, and we don't want the Used_Operations
8896 carried over from the original context (where it was probably
8897 not redundant).
8899 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8901 * exp_ch6.adb: Minor reformatting.
8903 2017-04-25 Bob Duff <duff@adacore.com>
8905 * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings):
8906 Use Source_Index (Current_Sem_Unit) to find the correct casing.
8907 * exp_prag.adb (Expand_Pragma_Check): Use Source_Index
8908 (Current_Sem_Unit) to find the correct casing.
8909 * par.adb (Par): Null out Current_Source_File, to ensure that
8910 the above bugs won't rear their ugly heads again.
8912 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8914 * sem_ch8.adb (Find_Type): For an attribute reference
8915 'Class, if prefix type is synchronized and previous errors
8916 have suppressed the creation of the corresponding record type,
8917 create a spurious class-wide for the synchonized type itself,
8918 to catch other misuses of the attribute
8920 2017-04-25 Steve Baird <baird@adacore.com>
8922 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
8923 is True, then don't generate the accessibility check for the
8924 tag of a tagged result.
8925 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
8926 if CodePeer_Mode is True, then don't generate the
8927 tag checks for the result of call to an instance of
8928 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8929 descendant of" check and the accessibility check).
8931 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8933 * sem_ch13.adb: Code cleanups.
8934 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.
8935 * sem_ch8.ads: Minor comment fix.
8937 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8939 * exp_ch4.adb (Library_Level_Target): New function.
8940 (Expand_Concatenate): When optimization is enabled, also expand
8941 the operation out-of-line if the concatenation is present within
8942 the expression of the declaration of a library-level object and
8943 not only if it is the expression of the declaration.
8945 2017-04-25 Bob Duff <duff@adacore.com>
8947 * freeze.adb (Freeze_Object_Declaration): Do
8948 not Remove_Side_Effects if there is a pragma Linker_Section,
8949 because in that case we want static initialization in the
8950 appropriate section.
8952 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8954 * exp_dbug.adb: Minor rewording and reformatting.
8956 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8958 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8959 handle the proposed changes to rules concerning potentially
8960 unevaluated expressions, to include selected components that
8961 do not depend on discriminants, and indexed components with
8962 static indices.
8963 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8964 predicate in quantified expression, and fix bugs in the handling
8965 of case expressions and membership test.
8966 (Analyze_Attribute_Old_Result): use new predicate.
8967 (Analyze_Attribute, case Loop_Entry): ditto.
8969 2017-04-25 Bob Duff <duff@adacore.com>
8971 * s-secsta.adb (SS_Info): Add a comment
8972 explaining why we don't need to walk all the chunks in order to
8973 compute the total size.
8975 2017-04-25 Bob Duff <duff@adacore.com>
8977 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
8978 of the global name buffer to 4*Max_Line_Length.
8980 2017-04-25 Javier Miranda <miranda@adacore.com>
8982 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
8983 renaming entity for debug information, mark the entity as needing debug
8984 info if it comes from sources.
8986 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8988 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8989 restriction converning the use of 'Address where the prefix is
8990 of a controlled type.
8992 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8994 * exp_dbug.adb: In Debug_Renaming_Declaration,
8995 skip slices that are made redundant by an indexed component
8996 access.
8997 * atree.h: New definition for Original_Node.
8999 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

9006 Preanalyze_Spec_Expression so that resolution takes place as well.
9007 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
9008 internal calls that appear in preconditions of protected
9009 operations, in default values for same, and in contract guards
9010 for contract cases in SPARK.
9012 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
9014 * a-numaux.ads: Fix description of a-numaux-darwin
9015 and a-numaux-x86.
9016 (Double): Define to Long_Float.
9017 * a-numaux-vxworks.ads (Double): Likewise.
9018 * a-numaux-darwin.ads
9019 (Double): Likewise.
9020 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
9021 * a-numaux-x86.ads: Fix package description.
9022 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9023 (Reduce): Adjust and complete description. Call Is_Nan instead of
9024 testing manually. Use an integer temporary to hold rounded value.
9025 * a-numaux-darwin.adb (Reduce): Likewise.
9026 (Is_Nan): New function.
9028 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9030 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9031 on analysis of prefix whose type is a current instance of a
9032 synchronized type, but where the prefix itself is an entity that
9033 is an object.
9035 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9037 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9038 the identity of callable entities therein, because they have been
9039 properly resolved, and prefixed calls may have been rewritten
9040 as normal calls.
9042 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9044 * exp_ch3.adb (Build_Init_Statements): Convert
9045 the expression of the pragma/aspect Secondary_Stack_Size to
9046 internal type System.Parameters.Size_Type before assigning
9047 it to the Secondary_Stack_Size component of the task type's
9048 corresponding record.
9050 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
9052 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
9053 (etc) optimizations when the type is modular and the offsets
9054 are equal.
9056 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
9058 * s-osinte-freebsd.ads: Minor comment tweaks
9060 2017-04-25 Javier Miranda <miranda@adacore.com>
9062 * urealp.adb (UR_Write): Reverse previous patch
9063 adding documentation on why we generate multiplications instead
9064 of divisions (needed to avoid expressions whose computation with
9065 large numbers may cause division by 0).
9067 2017-04-25 Bob Duff <duff@adacore.com>
9069 * erroutc.adb (Set_Specific_Warning_Off,
9070 Set_Warnings_Mode_Off): Use the correct source file for
9071 Stop. Was using Current_Source_File, which is only valid during
9072 parsing. Current_Source_File will have a leftover value from
9073 whatever file happened to be parsed last, because of a with_clause
9074 or something.
9076 2017-04-25 Bob Duff <duff@adacore.com>
9078 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9079 to In_Predefined_Unit, but including GNAT units.
9080 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9081 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9082 because Should_Ignore_Pragma was not working reliably outside
9083 the parser, because Current_Source_File is not valid.
9084 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9085 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9089 * gnat1drv.adb (Gnat1Drv): Disable Generate_Processed_File in
9090 codepeer mode.
9092 2017-04-25 Javier Miranda <miranda@adacore.com>
9094 * urealp.adb (UR_Write): Fix output of constants with a base other
9095 that 10.
9097 2017-04-25 Justin Squirek <squirek@adacore.com>
9099 * sem_ch13.adb (Get_Interfacing_Aspects): Moved to sem_util.adb.
9100 * sem_prag.adb (Analyze_Pragma, Process_Import_Or_Interface):
9101 Add extra parameter for Process_Interface_Name.

9120 Restored, code moved back from Build_Invariant_Procedure_Body.
9121 (Add_Parent_Invariants): Restored, code moved back from
9122 Build_Invariant_Procedure_Body.
9123 (Build_Invariant_Procedure_Body):
9124 Remove refactored calls and integrated code from
9125 Add_Parent_Invariants and Add_Interface_Invariants.
9127 2017-04-25 Johannes Kanig <kanig@adacore.com>
9129 * errout.adb (Output_Messages): Adjust computation of total
9130 errors
9131 * erroutc.adb (Error_Msg): In statistics counts, deal
9132 correctly with informational messages that are not warnings.
9133 * errutil.adb (Finalize): adjust computation of total errors.

9150 logic.
9152 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9154 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9155 of prefix whose type is a current instance of a synchronized
9156 type. If the prefix is an object this is an external call (or
9157 requeue) that can only access public operations of the object. The
9158 previous predicate was too restrictive, and did not allow public
9159 protected operations, only task entries.
9161 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9163 * sem_ch5.adb, fname.adb: Minor reformatting.
9165 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

9168 * einfo.ads Update the placement of
9169 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9170 mention the ekind.
9171 (Is_Anonymous_Access_Type): New routine.
9172 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9173 master for an access type subject to pragma No_Heap_Finalization.
9174 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9175 allocated or deallocated does not finalization actions if the
9176 associated access type is subject to pragma No_Heap_Finalization.
9177 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9178 * par-prag.adb Pragma No_Heap_Finalization does not need special
9179 processing from the parser.
9180 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9181 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9182 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9183 No_Heap_Finalization.
9184 (Analyze_Pragma): Add processing for
9185 pragma No_Heap_Finalization. Update various error messages to
9186 use Duplication_Error.

9193 * freeze.adb (Freeze_Record_Type): Use the
9194 underlying type of the component type to determine whether it's
9195 elementary. For representation clause purposes, a private type
9196 should behave the same as its full type.
9197 * fname.ads, fname.adb (Is_Predefined_File_Name):
9198 Make sure things like "system.ali" are recognized as predefined.
9200 2017-04-25 Javier Miranda <miranda@adacore.com>

9206 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9207 element iterator when the name is an overloaded function call,
9208 one of whose interpretations yields an array.
9210 2017-04-25 Bob Duff <duff@adacore.com>
9212 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9213 Is_Internal_Unit_Name): New functions for operating on unit
9214 names, as opposed to file names. There's some duplicated code
9215 with fname.adb, which is unfortunate, but it seems like we don't
9216 want to add dependencies here.
9217 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9218 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9219 is not a file name at all.
9220 * fname.ads, fname.adb: Document the fact that
9221 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9222 for ALI files, and fix the code so it works properly for ALI
9223 files. E.g. these should return True for "system.ali".
9225 2017-04-25 Justin Squirek <squirek@adacore.com>
9227 * exp_util.adb (Add_Invariant): Removed,
9228 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9229 and Add_Own_Invariant. (Add_Invariant_Check): Used
9230 for adding runtime checks from any kind of invariant.
9231 (Add_Inherited_Invariant): Generates invariant checks for

9237 and integrated code from Add_Parent_Invariants and
9238 Add_Interface_Invariants.
9239 (Process_Type): Removed, the
9240 relavant code was inlined into both Add_Own_Invariant and
9241 Add_Inherited_Invariant.

9264 and Build_Invariant_Procedure_Declaration from exp_ch7
9265 and break-out Is_Untagged_Private_Derivation from
9266 Build_Invariant_Procedure_Body.
9267 (Replace_Type_References):
9268 Append an extra parameter to allow for dispatching replacements
9269 and add the corrasponding logic.
9270 (Type_Invariant): Remove
9271 Replace_Typ_Refs and replace its references with calls to
9272 Replace_Type_References.
9273 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9275 2017-04-25 Bob Duff <duff@adacore.com>

9278 that returns True when appropriate.
9279 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9280 when compiling predefined files.
9281 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9282 "gnat.adc" should not be considered a predefined file name.
9283 That required (or at least encouraged) a lot of cleanup of global
9284 variable usage. We shouldn't be communicating information via
9285 the global name buffer.
9286 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9287 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9346 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9347 the first pass over an assignment statement with target names,
9348 to prevent the generation of subtypes (such as discriminated
9349 record components)that may carry the target name outside of the

9351 the assignment is reanalyzed in full.
9352 (Analyze_Target_Name): Handle properly class-wide types.

9387 DIC pragma is placed at the top of a declarative region.
9389 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

9397 the error message when the attribute reference is an actual in
9398 a call to a subprogram inherited from a generic formal type with
9399 unknown discriminants, which makes the subprogram and its formal
9400 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9402 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9404 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9409 * sem_attr.adb (Type_Key): Add code in the
9410 recursive Compute_Type_Key to protect against fetching the source
9411 code for Standard, in case a component of the type is declared

9434 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
9435 context is a package declaration.

10122 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10123 report on spurious overlaps between values involving a subtype
10124 with a static predicate, because the expansion of such a subtype
10125 into individual ranges in inhibited in ASIS mode.
10127 2017-01-23 Justin Squirek <squirek@adacore.com>
10129 * sem_ch3.adb (Analyze_Declarations): Add detection

10155 * exp_spark.adb (Expand_SPARK_Attribute_Reference): For
10156 attributes which return Universal_Integer, introduce a conversion
10157 to the expected type with the appropriate check flags set.
10158 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10159 base type if the range is null. It may still be invalid if it

10176 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10177 an object declaration for an array type with a modular index type
10178 with the size of Long_Long_Integer. Special processing is needed
10179 in this case to compute reliably the size of the object, and
10180 eventually to raise Storage_Error, when wrap-around arithmetic
10181 might compute a meangingless size for the object.
10183 2017-01-23 Justin Squirek <squirek@adacore.com>
10185 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10190 * sem_res.adb (Resolve_Call): In the part of the code where
10191 it is deciding whether to turn the call into an indexed
10192 component, avoid doing so if the call is to an instance of
10193 Unchecked_Conversion. Otherwise, the compiler turns it into an
10194 indexed component, and resolution of that turns it back into a
10195 function call, and so on, resulting in infinite recursion.
10196 * sem_util.adb (Needs_One_Actual): If the first formal has a
10197 default, then return False.

10244 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10245 must be treated as delayed aspect even if the expression is
10246 a literal, because the aspect affects the freezing and the
10247 elaboration of the object to which it applies.
10249 2017-01-20 Tristan Gingold <gingold@adacore.com>
10251 * s-osinte-vxworks.ads (Interrup_Range): New subtype.

10299 returns a limited view of a type and at the point of the call the
10300 function is not declared in the extended main unit then replace
10301 it with the non-limited view, which must be available. If the
10302 called function is in the extended main unit then no action is
10303 needed since the back-end handles this case.

10321 anomalies in gigi.
10323 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
10325 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10326 When inheriting the SPARK_Mode of a prior expression function,

10417 * sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
10418 aspect Implicit_Dereference can be inherited by a full view if

10588 * lib-xref-spark_specific.adb
10589 (Add_SPARK_Xrefs): Simplify iteration over dereferences.
10591 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10593 * exp_ch4.adb (Expand_Concatenate): Do no enable overflow
10594 checks on the expression for the high bound of concatenation
10595 when checks are disabled, to suppress warnings about potential
10596 constraint errors in restricted runtimes.

10607 2017-01-19 Javier Miranda <miranda@adacore.com>
10609 * exp_ch6.adb (Expand_Call): Remove side effects on
10610 actuals that are allocators with qualified expression since the
10611 initialization of the object is performed by means of individual
10612 statements (and hence it must be done before the call).
10614 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10616 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10617 (Build_Derived_Enumeration_Type): If the derived type inherits a
10618 dynamic predicate from its parent, the bounds of the type must
10619 freeze because an explicit constraint is constructed for the
10620 type and the corresponding range is elaborated now.

10652 an Inlined_body, recognize a call that uses object notation
10653 and has not been rewritten as a regular call because regular
10654 expansion has not taken place.
10656 2017-01-19 Bob Duff <duff@adacore.com>
10658 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10659 in case of generic formal discrete types, because it causes crashes in

10672 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10673 these variables to be of subtype Nat instead of Int, because
10674 they should never be negative.

10707 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10708 selected component has a prefix that might be interpreted
10709 as a parameterless function call, but none of the candidate
10710 interpretations is parameterless, and there is a hidden homonym
10711 of the prefix that is a package.
10712 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10713 interpreted as a parameterless function call and its analysis
10714 fails, do not call Analyze_Selected_Component.
10716 2017-01-19 Steve Baird <baird@adacore.com>

10728 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10729 from repeated code of Traverse_Compilation_Unit.
10730 (Traverse_Declaration_Or_Statement): fixed detection of
10731 generic subprograms and packages; also, iteration over case
10732 statement alternatives rewritten to avoid testing if the first
10733 alternative is present (since it must be present due to Ada
10734 syntax restrictions).

10873 * binde.adb (Elab_New): New elaboration order algorithm
10874 that is expected to cause fewer ABE issues. This is a work in
10875 progress. The new algorithm is currently disabled, and can be
10876 enable by the -dp switch, or by modifying the Do_Old and Do_New
10877 etc. flags and rebuilding. Experimental code is included to
10878 compare the results of the old and new algorithms.
10879 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10880 can have multiple of these tables, so the old and new algorithms
10881 can coexist.
10882 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10883 parameter of type array. This avoids the global variable, and
10884 allows bounds checking (which is normally defeated by the tables
10885 packages). It also ensures that the Elab_Order is read-only
10886 to Bindgen.
10887 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all

11016 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11017 Loop_Actions and Box_Present are attributes of
11018 N_Iterated_Component_Association nodes. Box_Present is always
11019 False in this case.
11020 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11021 has a Discrete_Choices list, as specified in the RM. A
11022 Component_Association for aggregate uses instead a Choices list.
11023 We have to live with this small inconsistency because the new

11037 Analyze_Declarations, to analyze and resolve the expressions of
11038 aspect specifications in the current declarative list, so that
11039 the expressions have proper entity and type info. This is needed
11040 for ASIS when there is no subsequent expansion to generate this
11041 semantic information.
11042 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11043 original expression, to suppress cascaded errors when expression
11044 has been constant-folded.
11045 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11046 ASIS mode, because there is no subsequent expansion to decorate
