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

460 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
461 a package body that is a compilation unit may contain blocks that
462 declare local subprograms. In Subprogram_Unnesting Mode such
463 subprograms must be handled as nested inside the (implicit) elaboration
464 procedure that executes that statement part. To handle properly uplevel
465 references we construct that subprogram explicitly, to contain blocks
466 and inner subprograms, The statement part of the compilation unit
467 becomes a call to this subprogram. This is only done if blocks are
468 present in the statement list of the body.

539 tagged type. In such case, collecting the list of primitives we may
540 find two equality primitives: one associated with the untagged private
541 and another associated with the ultimate tagged type (and we must
542 remove from the returned list this latter one).

555 * exp_ch6.adb (Expand_N_Subprogram_Body): Do not generate push/pop for
556 exceptions if subprogram unnesting is in effect, because these branch
557 nodes are relevant only in the presence of nested subprograms.

579 carry no type. Such selected components appear in unit names that are
580 child units, both in the specification and possibly in an end label for
581 the unit, and they do not contain any relevant uplevel references.

601 * vx_crtbegin.inc: Use a consistent naming convention for the
602 registration/deregistration functions across RTP or kernel. Remove the
603 ctor/dtor attribute setting based on RTP/kernel, expect the optional
604 attribute extension to be provided by includers instead.
605 * vx_crtbegin.c: Mere inclusion of vx_crtbegin.inc with empty attribute

775 references, examine index expressions or associated expressions as well
776 to record uplevel references.

778 unconstrained array and the actual is constrained, check whether bounds
779 of actual have uplevel references.
781 2018-05-28 Ed Schonberg <schonberg@adacore.com>
783 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
784 they can appear as components of activation records.

803 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
804 value when converting a float value to a fixed-point value. This is
805 required for CCG because it handles fixed-point types by means of
806 unsigned integer type variables. The range check is now performed using
807 the integer value stored in this temporary.
809 2018-05-28 Yannick Moy <moy@adacore.com>
811 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
812 Length as valid non-interfering contexts for SPARK.

816 * sem_disp.ads, sem_disp.adb (Inheritance_Utilities): Package for
817 generic inheritance utilities.

838 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
839 access-to-subprogram types, to indicate that an indirect call through
840 such a type requires an activation record when compiling for LLVM.
841 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
843 2018-05-28 Ed Schonberg <schonberg@adacore.com>
845 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
846 when bounds of fixed type are static, to remove some spuerfluous
847 implicit conversions and provide an accurate result when converting
848 back and forth between the fixed point type and a floating point type.
850 2018-05-28 Ed Schonberg <schonberg@adacore.com>

855 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
857 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
858 replaced, if any; all callers changed.
859 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
860 constant with private view so we take the address of that entity.
861 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
862 any; all callers changed. Handle N_Indexed_Component like
863 N_Attribute_Reference. Add N_Type_Conversion case.
864 (Visit_Node): Indexed references can be uplevel if the type isn't
866 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
867 been relocated, set first_named pointer in original node as well.
869 2018-05-28 Ed Schonberg <schonberg@adacore.com>
871 * exp_aggr.adb (Flatten): Copy tree of expression in a component
872 association with a range or a set of discrete choices, rather than
873 relocating the node. This avoids inconsistencies in the tree when
874 handling nested subprograms with uplevel references for LLVM.

888 unnecessary use of 'Unrestricted_Access.

940 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
941 includes a call to function to which it applies. This may mean an
942 omission of an attribute reference 'Result, in particular if the
943 function is pqrameterless.
945 2018-05-28 Justin Squirek <squirek@adacore.com>

959 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
960 end with the linker section, if any.
961 (List_Entities): Do not output the linker section for record types,
962 array types and variables.
963 (Print_Expr): Factor out common processing for unary operators and
964 special values. Adjust and reorder the various cases.
965 (List_Object_Info): End with the linker section, if any.
966 (List_Record_Info): Likewise.

972 that the result will be either -infinite or +infinite.
974 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
976 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
977 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
978 Expand range of type to match the address space of the target.
979 (Task_Storage_Size): Remove unused type.
981 2018-05-25 Ed Schonberg <schonberg@adacore.com>
983 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
984 of a fixed point type and the parent is a multiplying operation,
985 resolve the operand with its own type because the context will impose a
986 resulting type on the result of the multiplication by means of
987 approriate conversion.
989 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
991 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
992 the in-place initialization aggregate created for pragmas
993 Initialize_Scalars or Normalize_Scalars is performed with checks
996 2018-05-25 Arnaud Charlet <charlet@adacore.com>
998 * exp_aggr.adb (Convert_To_Positional): Bump default for
999 Max_Others_Replicate to 32. Update comments.
1000 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1001 (No_File_Info_Cache): Initialize separately.

1020 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1022 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1023 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1024 into three distring cases rather than in one loop which attempts to
1025 handle all three cases. This rewrite eliminates an issue where the last
1026 frame of the stack cannot be freed, thus causing the memory range of a
1027 new frame to approach the overflow point of the memory index type.
1028 Since the overflow is logically treated as a
1029 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1030 (SS_Allocate_Static): New routine. The routine factorizes the static
1031 secondary stack-related code from the former SS_Allocate.
1033 2018-05-25 Sergey Rybin <rybin@adacore.com>
1035 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1036 option for gnatelim.

1040 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1041 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1042 is created when the proper body of the stub is analyzed.
1043 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1044 is the proper body of a subunit, the cloned body must be inserted in
1045 the declarative list that contains the stub.
1047 2018-05-25 Justin Squirek <squirek@adacore.com>
1049 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1050 generate code for 6.5(8-10) so that we don't get an assertion error
1051 when dealing with an incomplete return type.
1053 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1084 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1085 Validate_Derived_Type_Instance, to verify that all interfaces
1086 implemented by the formal type are also implemented by the actual. The

1088 in a generic unit and the actual is declared in an instance of it.
1089 There is currently no mechanism to relate an interface declared within
1090 a generic to the corresponding interface in an instance, so we must
1091 traverse the list of interfaces of the actual, looking for a name
1092 match, and verifying that that interface is declared in an instance.

1661 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
1662 iteration of an Ada2012 loop is performed to determine the type of the
1663 domain, but full analysis is performed once the loop is rewritten as a

1665 must also suppress the generation of freeze nodes, which may otherwise
1666 appear in the wrong scope before rewritting.

2328 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2329 delegate the secondary stack management when there is no suitable

2536 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2538 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
2539 Establish_Transient_Scope.
2540 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
2541 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
2542 * exp_ch6.adb (Expand_Call_Helper): Update the call to
2543 Establish_Transient_Scope.
2544 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2545 Establish_Transient_Scope.
2546 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2547 management of the secondary stack to an enclosing scope if there is no
2548 suitable construct to wrap, and the transient scope was intended to
2549 manage the secondary stack.
2550 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2551 is a valid boundary for a transient expression which comes from the
2552 statements of the alternative, otherwise alternatives cannot be
2553 wrapped. Assignments of controlled objects which have controlled
2554 actions suppressed now stop the traversal as there is no point in
2555 looking for an enclosing construct. Add several N_xxx_Body choices to
2556 the termination conditions for completeness.
2557 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2558 and the associated comment on usage.
2559 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2560 Establish_Transient_Scope.
2561 (Add_Write_After): Update the call to Establish_Transient_Scope.
2562 * sem_res.adb (Check_Initialization_Call): Removed.
2563 (Resolve_Actuals): Account for additional cases where finalization
2564 actions are required by utilizing predicate Needs_Finalization rather
2566 (Resolve_Call): Type initialization procedures can now utilize
2567 transient scopes to manage the secondary stack, thus preventing leaks
2568 during initialization. Remove the previous kludgy algorithm which
2569 attempts to manage the secondary stack at the object creation site.
2571 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2573 * libgnat/g-soliop__qnx.ads: New.

2604 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
2606 2018-01-11 Ben Brosgol <brosgol@adacore.com>
2608 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
2610 * gnat_rm.texi: Regenerate.
2612 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2614 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2615 formsl type corresponding to the actual fixed point type is private,
2616 because in this case there can be no suspicious arithmetic operations
2617 in the generic unless they reference a formal subprogram. Clarify
2620 2018-01-11 Javier Miranda <miranda@adacore.com>
2622 * exp_util.adb (Remove_Side_Effects): No action done for functions
2623 returning class-wide types since it requires generating code using
2624 'reference and the CCG target has no secondary stack.
2625 * gnat1drv.adb: Disable building static dispatch tables when generating
2628 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2630 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
2631 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
2632 (File_Type): Add Default_Initial_Condition aspect.
2634 2018-01-11 Pascal Obry <obry@adacore.com>
2636 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2638 2018-01-11 Bob Duff <duff@adacore.com>
2640 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2641 to match what the Libadalang-based version does.
2642 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2644 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2646 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2647 if it contains at least one component declaration employing a function
2648 call returning on the secondary stack.
2650 2018-01-11 Yannick Moy <moy@adacore.com>
2652 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2653 Update description of restriction SPARK_05 with SPARK 2014.

2662 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2663 sem_res.adb, sem_util.adb: Minor reformatting.
2665 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2667 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2668 has a delayed aspect which must be processed at the point the type is
2669 frozen. This mimics what is done when the predicate is provided by a
2672 2018-01-11 Doug Rupp <rupp@adacore.com>
2674 * init.c (vxworks): Add macro checks for __aarch64__.
2676 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2678 * exp_util.adb (Add_Failure_Expression): New routine.
2679 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2680 * sem_util.adb (Is_Current_Instance): Code cleanup.
2682 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2684 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2685 Default_Sec_Stack_Size.
2686 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2687 limit check so that the integer index does not overflow. Check the
2688 dynamic stack allocation does not cause the secondary stack pointer to
2690 (SS_Info): Align colons.
2691 (SS_Init): Cover the case when bootstraping with an old compiler that
2692 does not set Default_SS_Size.
2694 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2696 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2697 legality of an inherited operation that may require overriding, ignore
2698 primitive_wrappers that correspond to explicit operations that override
2699 an interface primitive.
2700 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2701 operation to which the class-wide expression applies is a protected op.
2702 with a primitive_wrapper, verify that the updated inherited expression
2703 does not contain an internal call to a protected function. This
2704 completes the implementation of AI12-0166.
2706 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2708 * ali.adb: Document the remaining letters available for ALI lines.
2709 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2710 * ali.ads: Update type With_Record. Field
2711 Implicit_With_From_Instantiation is no longer in use. Add field
2713 * csinfo.adb (CSinfo): Remove the setup for attribute
2714 Implicit_With_From_Instantiation.
2715 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2716 either implicitly or explicitly withed.
2717 (Is_Implicit_With_Clause): New routine.
2718 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2719 confusion with the with clause attribute by the same name.
2720 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2721 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2722 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2723 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2725 (Implicit_With_On_Parent): Mark the with clause as generated for a
2727 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2728 instantiation are no longer marked as Implicit_With_From_Instantiation
2729 because they are already marked as implicit.
2730 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2731 which marks implicit with clauses as related to an instantiation.
2732 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2733 (Parent_With): New routine.
2734 (Set_Implicit_With_From_Instantiation): Removed.
2735 (Set_Parent_With): New routine.
2736 * sinfo.ads: Update the documentation of attribute Implicit_With.
2737 Remove attribute Implicit_With_From_Instantiation along with
2738 occurrences in nodes. Add attribute Parent_With along with occurrences

2745 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2747 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2748 entity when the enclosing construct is a body.
2750 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2752 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2753 Secondary_Stack_Size handling as a pragma is now generated for the
2754 corresponding aspect instead of an attribute. Pragma expression is
2755 relocated instead of evaluated. Discriminant of the corresponding
2756 record type is referenced rather than the type discriminant.
2757 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2758 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2759 * sem_ch13.adb (Analyze_One_Aspect): Transform
2760 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2761 because the attribute does not have visibility on a task type's

2763 (Analyze_Attribute_Definition_Clause): Remove handling of
2764 Attribute_Secondary_Stack_Size.
2765 * snames.adb-tmpl, snames.ads-tmpl: Remove
2766 Attribute_Secondary_Stack_Size, no longer used.
2768 2018-01-11 Justin Squirek <squirek@adacore.com>

2772 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2774 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2775 individual action because the action may denote a complex expression,
2776 such as a case statement, which in turn may contain additional
2779 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2781 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2782 analysis on a copy of the expression with a copy of the index variable,
2783 because full expansion will rewrite construct into a loop with the
2784 original loop variable.
2785 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2786 expression is an iterated component association. Full analysis takes
2787 place when construct is rewritten as a loop.
2788 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2789 is not safe for in-place assignment.
2790 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2791 entity with no homonym and no other entity in the scope.
2793 2018-01-11 Justin Squirek <squirek@adacore.com>
2795 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2796 message to be printed on the pragma argument identifier.
2798 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2800 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2801 entity of the generated invariant procedure in order to construct a
2802 proper entity chain.
2804 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2806 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in

2811 * einfo.ads, einfo.adb (Activation_Record_Component,
2812 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2813 Allow E_Discriminant.
2815 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2817 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2818 for atomic access once the component size is taken into account and
2819 also do it if the component type is Atomic or Volatile_Full_Access.
2821 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2823 * gnatvsn.ads: Bump copyright year.
