414 comment about the memset case.
416 2018-05-30 Bob Duff <duff@adacore.com>
418 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
419 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
420 We need to analyze it as part of analyzing the block, so that if the
421 call to Element that initializes Elmt_Decl returns on the secondary
422 stack, the block will ss_mark/ss_release. This block is inside the
423 loop; we don't want to leak memory until the loop exits. The purpose
424 of analyzing Elmt_Decl first was to catch the error of modifying it,
425 which is illegal because it's a loop parameter. The above causes us to
426 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
427 it on the Element entity, so we end up with an E_Variable node with the
429 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
430 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
431 parameter not allowed" error if Is_Loop_Parameter.
432 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

447 2018-05-30 Ed Schonberg <schonberg@adacore.com>
449 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
450 a package body that is a compilation unit may contain blocks that
451 declare local subprograms. In Subprogram_Unnesting Mode such
452 subprograms must be handled as nested inside the (implicit) elaboration
453 procedure that executes that statement part. To handle properly uplevel
454 references we construct that subprogram explicitly, to contain blocks
455 and inner subprograms, The statement part of the compilation unit
456 becomes a call to this subprogram. This is only done if blocks are
457 present in the statement list of the body.

569 child units, both in the specification and possibly in an end label for
570 the unit, and they do not contain any relevant uplevel references.

590 * vx_crtbegin.inc: Use a consistent naming convention for the
591 registration/deregistration functions across RTP or kernel. Remove the
592 ctor/dtor attribute setting based on RTP/kernel, expect the optional
593 attribute extension to be provided by includers instead.

767 unconstrained array and the actual is constrained, check whether bounds
768 of actual have uplevel references.
770 2018-05-28 Ed Schonberg <schonberg@adacore.com>
772 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

793 value when converting a float value to a fixed-point value. This is
794 required for CCG because it handles fixed-point types by means of
795 unsigned integer type variables. The range check is now performed using
796 the integer value stored in this temporary.
798 2018-05-28 Yannick Moy <moy@adacore.com>
800 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
801 Length as valid non-interfering contexts for SPARK.

827 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
828 access-to-subprogram types, to indicate that an indirect call through
829 such a type requires an activation record when compiling for LLVM.
830 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
832 2018-05-28 Ed Schonberg <schonberg@adacore.com>
834 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
835 when bounds of fixed type are static, to remove some spuerfluous
836 implicit conversions and provide an accurate result when converting
837 back and forth between the fixed point type and a floating point type.
839 2018-05-28 Ed Schonberg <schonberg@adacore.com>

844 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
846 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
847 replaced, if any; all callers changed.
848 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
849 constant with private view so we take the address of that entity.
850 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
851 any; all callers changed. Handle N_Indexed_Component like
852 N_Attribute_Reference. Add N_Type_Conversion case.
853 (Visit_Node): Indexed references can be uplevel if the type isn't
855 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
856 been relocated, set first_named pointer in original node as well.
858 2018-05-28 Ed Schonberg <schonberg@adacore.com>
860 * exp_aggr.adb (Flatten): Copy tree of expression in a component
861 association with a range or a set of discrete choices, rather than
862 relocating the node. This avoids inconsistencies in the tree when
863 handling nested subprograms with uplevel references for LLVM.

929 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
930 includes a call to function to which it applies. This may mean an
931 omission of an attribute reference 'Result, in particular if the
932 function is pqrameterless.
934 2018-05-28 Justin Squirek <squirek@adacore.com>

948 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
949 end with the linker section, if any.
950 (List_Entities): Do not output the linker section for record types,
951 array types and variables.

953 special values. Adjust and reorder the various cases.
954 (List_Object_Info): End with the linker section, if any.
955 (List_Record_Info): Likewise.

961 that the result will be either -infinite or +infinite.
963 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
965 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
966 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
967 Expand range of type to match the address space of the target.
968 (Task_Storage_Size): Remove unused type.
970 2018-05-25 Ed Schonberg <schonberg@adacore.com>
972 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
973 of a fixed point type and the parent is a multiplying operation,
974 resolve the operand with its own type because the context will impose a
975 resulting type on the result of the multiplication by means of
976 approriate conversion.
978 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
980 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
981 the in-place initialization aggregate created for pragmas
982 Initialize_Scalars or Normalize_Scalars is performed with checks
985 2018-05-25 Arnaud Charlet <charlet@adacore.com>
987 * exp_aggr.adb (Convert_To_Positional): Bump default for
988 Max_Others_Replicate to 32. Update comments.
989 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
990 (No_File_Info_Cache): Initialize separately.

1009 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1011 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1012 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1013 into three distring cases rather than in one loop which attempts to
1014 handle all three cases. This rewrite eliminates an issue where the last
1015 frame of the stack cannot be freed, thus causing the memory range of a
1016 new frame to approach the overflow point of the memory index type.
1017 Since the overflow is logically treated as a
1018 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1019 (SS_Allocate_Static): New routine. The routine factorizes the static
1020 secondary stack-related code from the former SS_Allocate.
1022 2018-05-25 Sergey Rybin <rybin@adacore.com>
1024 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

1029 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1030 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1031 is created when the proper body of the stub is analyzed.
1032 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1033 is the proper body of a subunit, the cloned body must be inserted in
1034 the declarative list that contains the stub.
1036 2018-05-25 Justin Squirek <squirek@adacore.com>
1038 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1039 generate code for 6.5(8-10) so that we don't get an assertion error
1040 when dealing with an incomplete return type.
1042 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1073 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1074 Validate_Derived_Type_Instance, to verify that all interfaces
1075 implemented by the formal type are also implemented by the actual. The
1076 verification is complicated when an interface of the formal is declared
1077 in a generic unit and the actual is declared in an instance of it.
1078 There is currently no mechanism to relate an interface declared within
1079 a generic to the corresponding interface in an instance, so we must
1080 traverse the list of interfaces of the actual, looking for a name
1081 match, and verifying that that interface is declared in an instance.

2531 * exp_ch6.adb (Expand_Call_Helper): Update the call to
2532 Establish_Transient_Scope.
2533 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2534 Establish_Transient_Scope.
2535 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2536 management of the secondary stack to an enclosing scope if there is no
2537 suitable construct to wrap, and the transient scope was intended to
2538 manage the secondary stack.
2539 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2540 is a valid boundary for a transient expression which comes from the
2541 statements of the alternative, otherwise alternatives cannot be
2542 wrapped. Assignments of controlled objects which have controlled
2543 actions suppressed now stop the traversal as there is no point in
2544 looking for an enclosing construct. Add several N_xxx_Body choices to
2545 the termination conditions for completeness.
2546 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2547 and the associated comment on usage.
2548 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2549 Establish_Transient_Scope.
2550 (Add_Write_After): Update the call to Establish_Transient_Scope.
2551 * sem_res.adb (Check_Initialization_Call): Removed.
2552 (Resolve_Actuals): Account for additional cases where finalization
2553 actions are required by utilizing predicate Needs_Finalization rather
2555 (Resolve_Call): Type initialization procedures can now utilize
2556 transient scopes to manage the secondary stack, thus preventing leaks
2557 during initialization. Remove the previous kludgy algorithm which
2558 attempts to manage the secondary stack at the object creation site.
2560 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2562 * libgnat/g-soliop__qnx.ads: New.

2599 * gnat_rm.texi: Regenerate.
2601 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2603 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2604 formsl type corresponding to the actual fixed point type is private,
2605 because in this case there can be no suspicious arithmetic operations
2606 in the generic unless they reference a formal subprogram. Clarify
2609 2018-01-11 Javier Miranda <miranda@adacore.com>
2611 * exp_util.adb (Remove_Side_Effects): No action done for functions
2612 returning class-wide types since it requires generating code using
2613 'reference and the CCG target has no secondary stack.
2614 * gnat1drv.adb: Disable building static dispatch tables when generating
2617 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

2621 (File_Type): Add Default_Initial_Condition aspect.
2623 2018-01-11 Pascal Obry <obry@adacore.com>
2625 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2627 2018-01-11 Bob Duff <duff@adacore.com>
2629 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2630 to match what the Libadalang-based version does.
2631 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2633 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2635 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2636 if it contains at least one component declaration employing a function
2637 call returning on the secondary stack.
2639 2018-01-11 Yannick Moy <moy@adacore.com>
2641 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2642 Update description of restriction SPARK_05 with SPARK 2014.

2651 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2652 sem_res.adb, sem_util.adb: Minor reformatting.
2654 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2656 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2657 has a delayed aspect which must be processed at the point the type is
2658 frozen. This mimics what is done when the predicate is provided by a
2661 2018-01-11 Doug Rupp <rupp@adacore.com>
2663 * init.c (vxworks): Add macro checks for __aarch64__.
2665 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2667 * exp_util.adb (Add_Failure_Expression): New routine.

2669 * sem_util.adb (Is_Current_Instance): Code cleanup.
2671 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2673 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2674 Default_Sec_Stack_Size.
2675 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2676 limit check so that the integer index does not overflow. Check the
2677 dynamic stack allocation does not cause the secondary stack pointer to
2679 (SS_Info): Align colons.
2680 (SS_Init): Cover the case when bootstraping with an old compiler that
2681 does not set Default_SS_Size.
2683 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2685 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2686 legality of an inherited operation that may require overriding, ignore
2687 primitive_wrappers that correspond to explicit operations that override
2688 an interface primitive.
2689 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2690 operation to which the class-wide expression applies is a protected op.
2691 with a primitive_wrapper, verify that the updated inherited expression
2692 does not contain an internal call to a protected function. This
2693 completes the implementation of AI12-0166.
2695 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2697 * ali.adb: Document the remaining letters available for ALI lines.
2698 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2699 * ali.ads: Update type With_Record. Field
2700 Implicit_With_From_Instantiation is no longer in use. Add field
2702 * csinfo.adb (CSinfo): Remove the setup for attribute
2703 Implicit_With_From_Instantiation.
2704 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2705 either implicitly or explicitly withed.
2706 (Is_Implicit_With_Clause): New routine.
2707 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2708 confusion with the with clause attribute by the same name.
2709 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2710 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2711 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2712 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2714 (Implicit_With_On_Parent): Mark the with clause as generated for a
2716 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2717 instantiation are no longer marked as Implicit_With_From_Instantiation
2718 because they are already marked as implicit.
2719 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2720 which marks implicit with clauses as related to an instantiation.
2721 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2722 (Parent_With): New routine.
2723 (Set_Implicit_With_From_Instantiation): Removed.
2724 (Set_Parent_With): New routine.
2725 * sinfo.ads: Update the documentation of attribute Implicit_With.
2726 Remove attribute Implicit_With_From_Instantiation along with
2727 occurrences in nodes. Add attribute Parent_With along with occurrences

2730 (Parent_With): New routine along with pragma Inline.
2731 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2732 (Set_Parent_With): New routine along with pragma Inline.
2734 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2736 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2737 entity when the enclosing construct is a body.
2739 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2741 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2742 Secondary_Stack_Size handling as a pragma is now generated for the
2743 corresponding aspect instead of an attribute. Pragma expression is
2744 relocated instead of evaluated. Discriminant of the corresponding
2745 record type is referenced rather than the type discriminant.
2746 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2747 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2748 * sem_ch13.adb (Analyze_One_Aspect): Transform
2749 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2750 because the attribute does not have visibility on a task type's
2751 discriminants when the type's definition is expanded.
2752 (Analyze_Attribute_Definition_Clause): Remove handling of
2753 Attribute_Secondary_Stack_Size.
2754 * snames.adb-tmpl, snames.ads-tmpl: Remove
2755 Attribute_Secondary_Stack_Size, no longer used.

2761 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2763 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2764 individual action because the action may denote a complex expression,
2765 such as a case statement, which in turn may contain additional
2768 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2770 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2771 analysis on a copy of the expression with a copy of the index variable,
2772 because full expansion will rewrite construct into a loop with the
2773 original loop variable.
2774 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2775 expression is an iterated component association. Full analysis takes
2776 place when construct is rewritten as a loop.
2777 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2778 is not safe for in-place assignment.
2779 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2780 entity with no homonym and no other entity in the scope.
2782 2018-01-11 Justin Squirek <squirek@adacore.com>
2784 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2785 message to be printed on the pragma argument identifier.
2787 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2789 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2790 entity of the generated invariant procedure in order to construct a
2791 proper entity chain.
2793 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2795 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2798 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2800 * einfo.ads, einfo.adb (Activation_Record_Component,
2801 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2802 Allow E_Discriminant.
2804 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2806 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2807 for atomic access once the component size is taken into account and
2808 also do it if the component type is Atomic or Volatile_Full_Access.
2810 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2812 * gnatvsn.ads: Bump copyright year.
