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

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

540 untagged private types completed with a derivation of an untagged
541 private whose full view is a tagged type.
542 * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
544 (Collect_Primitive_Operations): Handle untagged private types completed
545 with a derivation of an untagged private type whose full view is a
546 tagged type. In such case, collecting the list of primitives we may
547 find two equality primitives: one associated with the untagged private
548 and another associated with the ultimate tagged type (and we must
549 remove from the returned list this latter one).

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

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

785 unconstrained array and the actual is constrained, check whether bounds
786 of actual have uplevel references.
788 2018-05-28 Ed Schonberg <schonberg@adacore.com>
790 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

811 value when converting a float value to a fixed-point value. This is
812 required for CCG because it handles fixed-point types by means of
813 unsigned integer type variables. The range check is now performed using
814 the integer value stored in this temporary.
816 2018-05-28 Yannick Moy <moy@adacore.com>
818 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
819 Length as valid non-interfering contexts for SPARK.

845 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
846 access-to-subprogram types, to indicate that an indirect call through
847 such a type requires an activation record when compiling for LLVM.

850 2018-05-28 Ed Schonberg <schonberg@adacore.com>
852 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
853 when bounds of fixed type are static, to remove some spuerfluous
854 implicit conversions and provide an accurate result when converting
855 back and forth between the fixed point type and a floating point type.
857 2018-05-28 Ed Schonberg <schonberg@adacore.com>

862 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
864 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
865 replaced, if any; all callers changed.
866 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
867 constant with private view so we take the address of that entity.
868 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
869 any; all callers changed. Handle N_Indexed_Component like
870 N_Attribute_Reference. Add N_Type_Conversion case.
871 (Visit_Node): Indexed references can be uplevel if the type isn't
873 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
874 been relocated, set first_named pointer in original node as well.
876 2018-05-28 Ed Schonberg <schonberg@adacore.com>
878 * exp_aggr.adb (Flatten): Copy tree of expression in a component
879 association with a range or a set of discrete choices, rather than
880 relocating the node. This avoids inconsistencies in the tree when
881 handling nested subprograms with uplevel references for LLVM.

947 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
948 includes a call to function to which it applies. This may mean an
949 omission of an attribute reference 'Result, in particular if the
950 function is pqrameterless.
952 2018-05-28 Justin Squirek <squirek@adacore.com>

979 that the result will be either -infinite or +infinite.
981 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
983 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

985 Expand range of type to match the address space of the target.

988 2018-05-25 Ed Schonberg <schonberg@adacore.com>
990 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
991 of a fixed point type and the parent is a multiplying operation,
992 resolve the operand with its own type because the context will impose a
993 resulting type on the result of the multiplication by means of
994 approriate conversion.
996 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
998 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
999 the in-place initialization aggregate created for pragmas
1000 Initialize_Scalars or Normalize_Scalars is performed with checks
1003 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1005 * exp_aggr.adb (Convert_To_Positional): Bump default for
1006 Max_Others_Replicate to 32. Update comments.
1007 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1008 (No_File_Info_Cache): Initialize separately.

1027 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1029 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1030 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1031 into three distring cases rather than in one loop which attempts to
1032 handle all three cases. This rewrite eliminates an issue where the last
1033 frame of the stack cannot be freed, thus causing the memory range of a
1034 new frame to approach the overflow point of the memory index type.
1035 Since the overflow is logically treated as a
1036 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1037 (SS_Allocate_Static): New routine. The routine factorizes the static
1038 secondary stack-related code from the former SS_Allocate.
1040 2018-05-25 Sergey Rybin <rybin@adacore.com>
1042 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

1047 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1048 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1049 is created when the proper body of the stub is analyzed.
1050 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1051 is the proper body of a subunit, the cloned body must be inserted in
1052 the declarative list that contains the stub.

1091 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1092 Validate_Derived_Type_Instance, to verify that all interfaces
1093 implemented by the formal type are also implemented by the actual. The
1094 verification is complicated when an interface of the formal is declared
1095 in a generic unit and the actual is declared in an instance of it.
1096 There is currently no mechanism to relate an interface declared within
1097 a generic to the corresponding interface in an instance, so we must
1098 traverse the list of interfaces of the actual, looking for a name
1099 match, and verifying that that interface is declared in an instance.

1545 a constrained array component.
1546 * einfo.adb: Subprograms for Predicated_Parent.
1547 (Predicate_Function): Use new attribute.
1548 * exp_util.adb (Make_Predicate_Call): If the predicate function is not
1549 available for a subtype, retrieve it from the base type, which may have

1668 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
1669 iteration of an Ada2012 loop is performed to determine the type of the
1670 domain, but full analysis is performed once the loop is rewritten as a
1671 while-loop during expansion. The pre-analysis suppresses expansion; it
1672 must also suppress the generation of freeze nodes, which may otherwise
1673 appear in the wrong scope before rewritting.

2534 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2535 scope of package Ada is Standard.
2537 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2539 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2540 subcomponent of the current entity when building the body for a dynamic
2541 predicate function for a record with composite subcomponents.
2543 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2545 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
2546 Establish_Transient_Scope.
2547 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
2548 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
2549 * exp_ch6.adb (Expand_Call_Helper): Update the call to
2550 Establish_Transient_Scope.
2551 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2552 Establish_Transient_Scope.
2553 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2554 management of the secondary stack to an enclosing scope if there is no
2555 suitable construct to wrap, and the transient scope was intended to
2556 manage the secondary stack.
2557 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2558 is a valid boundary for a transient expression which comes from the
2559 statements of the alternative, otherwise alternatives cannot be
2560 wrapped. Assignments of controlled objects which have controlled
2561 actions suppressed now stop the traversal as there is no point in
2562 looking for an enclosing construct. Add several N_xxx_Body choices to
2563 the termination conditions for completeness.
2564 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2565 and the associated comment on usage.
2566 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2567 Establish_Transient_Scope.
2568 (Add_Write_After): Update the call to Establish_Transient_Scope.
2569 * sem_res.adb (Check_Initialization_Call): Removed.
2570 (Resolve_Actuals): Account for additional cases where finalization
2571 actions are required by utilizing predicate Needs_Finalization rather
2573 (Resolve_Call): Type initialization procedures can now utilize
2574 transient scopes to manage the secondary stack, thus preventing leaks
2575 during initialization. Remove the previous kludgy algorithm which
2576 attempts to manage the secondary stack at the object creation site.
2578 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2580 * libgnat/g-soliop__qnx.ads: New.
2581 * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update
2584 2018-01-11 Bob Duff <duff@adacore.com>

2587 a null procedure occurs in a protected definition.
2589 2018-01-11 Bob Duff <duff@adacore.com>
2591 * binderr.ads, namet.ads: Minor reformatting.

2603 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2605 * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
2606 controlling argument of a dispatching call. freeze the corresponding
2609 2018-01-11 Ben Brosgol <brosgol@adacore.com>
2611 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
2613 2018-01-11 Ben Brosgol <brosgol@adacore.com>
2615 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
2617 * gnat_rm.texi: Regenerate.
2619 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2621 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2622 formsl type corresponding to the actual fixed point type is private,
2623 because in this case there can be no suspicious arithmetic operations
2624 in the generic unless they reference a formal subprogram. Clarify
2627 2018-01-11 Javier Miranda <miranda@adacore.com>
2629 * exp_util.adb (Remove_Side_Effects): No action done for functions
2630 returning class-wide types since it requires generating code using
2631 'reference and the CCG target has no secondary stack.
2632 * gnat1drv.adb: Disable building static dispatch tables when generating
2635 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2637 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
2638 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
2639 (File_Type): Add Default_Initial_Condition aspect.
2641 2018-01-11 Pascal Obry <obry@adacore.com>
2643 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2645 2018-01-11 Bob Duff <duff@adacore.com>
2647 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2648 to match what the Libadalang-based version does.
2649 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2651 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2653 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2654 if it contains at least one component declaration employing a function
2655 call returning on the secondary stack.
2657 2018-01-11 Yannick Moy <moy@adacore.com>
2659 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2660 Update description of restriction SPARK_05 with SPARK 2014.
2661 * gnat_rm.texi: Regenerate.
2663 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
2665 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
2667 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2669 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2670 sem_res.adb, sem_util.adb: Minor reformatting.
2672 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2674 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2675 has a delayed aspect which must be processed at the point the type is
2676 frozen. This mimics what is done when the predicate is provided by a
2679 2018-01-11 Doug Rupp <rupp@adacore.com>
2681 * init.c (vxworks): Add macro checks for __aarch64__.
2683 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2685 * exp_util.adb (Add_Failure_Expression): New routine.
2686 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2687 * sem_util.adb (Is_Current_Instance): Code cleanup.
2689 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2691 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2692 Default_Sec_Stack_Size.
2693 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2694 limit check so that the integer index does not overflow. Check the
2695 dynamic stack allocation does not cause the secondary stack pointer to
2697 (SS_Info): Align colons.
2698 (SS_Init): Cover the case when bootstraping with an old compiler that
2699 does not set Default_SS_Size.
2701 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2703 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2704 legality of an inherited operation that may require overriding, ignore
2705 primitive_wrappers that correspond to explicit operations that override
2706 an interface primitive.
2707 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2708 operation to which the class-wide expression applies is a protected op.
2709 with a primitive_wrapper, verify that the updated inherited expression
2710 does not contain an internal call to a protected function. This
2711 completes the implementation of AI12-0166.
2713 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2715 * ali.adb: Document the remaining letters available for ALI lines.
2716 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2717 * ali.ads: Update type With_Record. Field
2718 Implicit_With_From_Instantiation is no longer in use. Add field
2720 * csinfo.adb (CSinfo): Remove the setup for attribute
2721 Implicit_With_From_Instantiation.
2722 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2723 either implicitly or explicitly withed.
2724 (Is_Implicit_With_Clause): New routine.
2725 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2726 confusion with the with clause attribute by the same name.
2727 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2728 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2729 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2730 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2732 (Implicit_With_On_Parent): Mark the with clause as generated for a
2734 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2735 instantiation are no longer marked as Implicit_With_From_Instantiation
2736 because they are already marked as implicit.
2737 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2738 which marks implicit with clauses as related to an instantiation.
2739 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2740 (Parent_With): New routine.
2741 (Set_Implicit_With_From_Instantiation): Removed.
2742 (Set_Parent_With): New routine.
2743 * sinfo.ads: Update the documentation of attribute Implicit_With.
2744 Remove attribute Implicit_With_From_Instantiation along with
2745 occurrences in nodes. Add attribute Parent_With along with occurrences
2747 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2748 (Parent_With): New routine along with pragma Inline.
2749 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2750 (Set_Parent_With): New routine along with pragma Inline.
2752 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2754 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2755 entity when the enclosing construct is a body.
2757 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2759 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2760 Secondary_Stack_Size handling as a pragma is now generated for the
2761 corresponding aspect instead of an attribute. Pragma expression is
2762 relocated instead of evaluated. Discriminant of the corresponding
2763 record type is referenced rather than the type discriminant.
2764 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2765 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2766 * sem_ch13.adb (Analyze_One_Aspect): Transform
2767 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2768 because the attribute does not have visibility on a task type's
2769 discriminants when the type's definition is expanded.
2770 (Analyze_Attribute_Definition_Clause): Remove handling of
2771 Attribute_Secondary_Stack_Size.
2772 * snames.adb-tmpl, snames.ads-tmpl: Remove
2773 Attribute_Secondary_Stack_Size, no longer used.
2775 2018-01-11 Justin Squirek <squirek@adacore.com>
2777 * sem_ch8.adb: Minor comment fix.
2779 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2781 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2782 individual action because the action may denote a complex expression,
2783 such as a case statement, which in turn may contain additional
2786 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2788 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2789 analysis on a copy of the expression with a copy of the index variable,
2790 because full expansion will rewrite construct into a loop with the
2791 original loop variable.
2792 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2793 expression is an iterated component association. Full analysis takes
2794 place when construct is rewritten as a loop.
2795 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2796 is not safe for in-place assignment.
2797 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2798 entity with no homonym and no other entity in the scope.
2800 2018-01-11 Justin Squirek <squirek@adacore.com>
2802 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2803 message to be printed on the pragma argument identifier.
2805 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2807 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2808 entity of the generated invariant procedure in order to construct a
2809 proper entity chain.
2811 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2813 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2816 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2818 * einfo.ads, einfo.adb (Activation_Record_Component,
2819 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2820 Allow E_Discriminant.
2822 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2824 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2825 for atomic access once the component size is taken into account and
2826 also do it if the component type is Atomic or Volatile_Full_Access.
2828 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2830 * gnatvsn.ads: Bump copyright year.
