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

471 2018-05-30 Ed Schonberg <schonberg@adacore.com>
473 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
474 a package body that is a compilation unit may contain blocks that
475 declare local subprograms. In Subprogram_Unnesting Mode such
476 subprograms must be handled as nested inside the (implicit) elaboration
477 procedure that executes that statement part. To handle properly uplevel
478 references we construct that subprogram explicitly, to contain blocks
479 and inner subprograms, The statement part of the compilation unit
480 becomes a call to this subprogram. This is only done if blocks are
481 present in the statement list of the body.

544 * exp_ch4.adb (Expand_N_Op_Eq, Expand_Composite_Equality): Use the new
545 subprogram Inherits_From_Tagged_Full_View to identify more reliably
546 untagged private types completed with a derivation of an untagged
547 private whose full view is a tagged type.
548 * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
550 (Collect_Primitive_Operations): Handle untagged private types completed
551 with a derivation of an untagged private type whose full view is a
552 tagged type. In such case, collecting the list of primitives we may
553 find two equality primitives: one associated with the untagged private
554 and another associated with the ultimate tagged type (and we must
555 remove from the returned list this latter one).

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

791 unconstrained array and the actual is constrained, check whether bounds
792 of actual have uplevel references.
794 2018-05-28 Ed Schonberg <schonberg@adacore.com>
796 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

817 value when converting a float value to a fixed-point value. This is
818 required for CCG because it handles fixed-point types by means of
819 unsigned integer type variables. The range check is now performed using
820 the integer value stored in this temporary.
822 2018-05-28 Yannick Moy <moy@adacore.com>

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

856 2018-05-28 Ed Schonberg <schonberg@adacore.com>
858 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
859 when bounds of fixed type are static, to remove some spuerfluous
860 implicit conversions and provide an accurate result when converting
861 back and forth between the fixed point type and a floating point type.

868 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
870 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
871 replaced, if any; all callers changed.
872 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
873 constant with private view so we take the address of that entity.
874 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
875 any; all callers changed. Handle N_Indexed_Component like
876 N_Attribute_Reference. Add N_Type_Conversion case.
877 (Visit_Node): Indexed references can be uplevel if the type isn't
879 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
880 been relocated, set first_named pointer in original node as well.
882 2018-05-28 Ed Schonberg <schonberg@adacore.com>
884 * exp_aggr.adb (Flatten): Copy tree of expression in a component
885 association with a range or a set of discrete choices, rather than
886 relocating the node. This avoids inconsistencies in the tree when
887 handling nested subprograms with uplevel references for LLVM.

953 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
954 includes a call to function to which it applies. This may mean an
955 omission of an attribute reference 'Result, in particular if the
956 function is pqrameterless.
958 2018-05-28 Justin Squirek <squirek@adacore.com>

985 that the result will be either -infinite or +infinite.

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

994 2018-05-25 Ed Schonberg <schonberg@adacore.com>
996 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
997 of a fixed point type and the parent is a multiplying operation,
998 resolve the operand with its own type because the context will impose a
999 resulting type on the result of the multiplication by means of
1000 approriate conversion.
1002 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1004 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1005 the in-place initialization aggregate created for pragmas
1006 Initialize_Scalars or Normalize_Scalars is performed with checks
1009 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1011 * exp_aggr.adb (Convert_To_Positional): Bump default for
1012 Max_Others_Replicate to 32. Update comments.
1013 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1014 (No_File_Info_Cache): Initialize separately.

1033 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1035 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1036 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1037 into three distring cases rather than in one loop which attempts to
1038 handle all three cases. This rewrite eliminates an issue where the last
1039 frame of the stack cannot be freed, thus causing the memory range of a
1040 new frame to approach the overflow point of the memory index type.
1041 Since the overflow is logically treated as a
1042 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1043 (SS_Allocate_Static): New routine. The routine factorizes the static
1044 secondary stack-related code from the former SS_Allocate.

1053 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1054 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1055 is created when the proper body of the stub is analyzed.

1097 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1098 Validate_Derived_Type_Instance, to verify that all interfaces
1099 implemented by the formal type are also implemented by the actual. The

1101 in a generic unit and the actual is declared in an instance of it.
1102 There is currently no mechanism to relate an interface declared within
1103 a generic to the corresponding interface in an instance, so we must
1104 traverse the list of interfaces of the actual, looking for a name
1105 match, and verifying that that interface is declared in an instance.

1551 a constrained array component.
1552 * einfo.adb: Subprograms for Predicated_Parent.
1553 (Predicate_Function): Use new attribute.
1554 * exp_util.adb (Make_Predicate_Call): If the predicate function is not

1674 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
1675 iteration of an Ada2012 loop is performed to determine the type of the
1676 domain, but full analysis is performed once the loop is rewritten as a

1678 must also suppress the generation of freeze nodes, which may otherwise
1679 appear in the wrong scope before rewritting.

2532 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2534 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2535 categorization of a subprogram body which does not complete a previous
2538 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2540 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2541 scope of package Ada is Standard.
2543 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2545 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2546 subcomponent of the current entity when building the body for a dynamic
2547 predicate function for a record with composite subcomponents.
2549 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2551 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
2552 Establish_Transient_Scope.
2553 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
2554 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
2555 * exp_ch6.adb (Expand_Call_Helper): Update the call to
2556 Establish_Transient_Scope.
2557 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2558 Establish_Transient_Scope.
2559 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2560 management of the secondary stack to an enclosing scope if there is no
2561 suitable construct to wrap, and the transient scope was intended to
2562 manage the secondary stack.
2563 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2564 is a valid boundary for a transient expression which comes from the
2565 statements of the alternative, otherwise alternatives cannot be
2566 wrapped. Assignments of controlled objects which have controlled
2567 actions suppressed now stop the traversal as there is no point in
2568 looking for an enclosing construct. Add several N_xxx_Body choices to
2569 the termination conditions for completeness.
2570 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2571 and the associated comment on usage.
2572 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2573 Establish_Transient_Scope.
2574 (Add_Write_After): Update the call to Establish_Transient_Scope.
2575 * sem_res.adb (Check_Initialization_Call): Removed.
2576 (Resolve_Actuals): Account for additional cases where finalization
2577 actions are required by utilizing predicate Needs_Finalization rather
2579 (Resolve_Call): Type initialization procedures can now utilize
2580 transient scopes to manage the secondary stack, thus preventing leaks
2581 during initialization. Remove the previous kludgy algorithm which
2582 attempts to manage the secondary stack at the object creation site.
2584 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2586 * libgnat/g-soliop__qnx.ads: New.
2587 * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update

2593 a null procedure occurs in a protected definition.
2595 2018-01-11 Bob Duff <duff@adacore.com>
2597 * binderr.ads, namet.ads: Minor reformatting.

2617 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
2619 2018-01-11 Ben Brosgol <brosgol@adacore.com>
2621 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
2623 * gnat_rm.texi: Regenerate.
2625 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2627 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2628 formsl type corresponding to the actual fixed point type is private,
2629 because in this case there can be no suspicious arithmetic operations
2630 in the generic unless they reference a formal subprogram. Clarify
2633 2018-01-11 Javier Miranda <miranda@adacore.com>
2635 * exp_util.adb (Remove_Side_Effects): No action done for functions
2636 returning class-wide types since it requires generating code using
2637 'reference and the CCG target has no secondary stack.
2638 * gnat1drv.adb: Disable building static dispatch tables when generating
2641 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2643 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
2644 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
2645 (File_Type): Add Default_Initial_Condition aspect.
2647 2018-01-11 Pascal Obry <obry@adacore.com>
2649 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2651 2018-01-11 Bob Duff <duff@adacore.com>
2653 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2654 to match what the Libadalang-based version does.
2655 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2657 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2659 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2660 if it contains at least one component declaration employing a function
2661 call returning on the secondary stack.
2663 2018-01-11 Yannick Moy <moy@adacore.com>
2665 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2666 Update description of restriction SPARK_05 with SPARK 2014.
2667 * gnat_rm.texi: Regenerate.
2669 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>

2675 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2676 sem_res.adb, sem_util.adb: Minor reformatting.
2678 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2680 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2681 has a delayed aspect which must be processed at the point the type is
2682 frozen. This mimics what is done when the predicate is provided by a
2685 2018-01-11 Doug Rupp <rupp@adacore.com>
2687 * init.c (vxworks): Add macro checks for __aarch64__.
2689 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2691 * exp_util.adb (Add_Failure_Expression): New routine.
2692 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2693 * sem_util.adb (Is_Current_Instance): Code cleanup.
2695 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2697 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2698 Default_Sec_Stack_Size.
2699 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2700 limit check so that the integer index does not overflow. Check the
2701 dynamic stack allocation does not cause the secondary stack pointer to
2703 (SS_Info): Align colons.
2704 (SS_Init): Cover the case when bootstraping with an old compiler that
2705 does not set Default_SS_Size.
2707 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2709 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2710 legality of an inherited operation that may require overriding, ignore
2711 primitive_wrappers that correspond to explicit operations that override
2712 an interface primitive.
2713 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2714 operation to which the class-wide expression applies is a protected op.
2715 with a primitive_wrapper, verify that the updated inherited expression
2716 does not contain an internal call to a protected function. This
2717 completes the implementation of AI12-0166.
2719 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2721 * ali.adb: Document the remaining letters available for ALI lines.
2722 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2723 * ali.ads: Update type With_Record. Field
2724 Implicit_With_From_Instantiation is no longer in use. Add field
2726 * csinfo.adb (CSinfo): Remove the setup for attribute
2727 Implicit_With_From_Instantiation.
2728 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2729 either implicitly or explicitly withed.
2730 (Is_Implicit_With_Clause): New routine.
2731 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2732 confusion with the with clause attribute by the same name.
2733 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2734 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2735 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2736 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2738 (Implicit_With_On_Parent): Mark the with clause as generated for a
2740 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2741 instantiation are no longer marked as Implicit_With_From_Instantiation
2742 because they are already marked as implicit.
2743 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2744 which marks implicit with clauses as related to an instantiation.
2745 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2746 (Parent_With): New routine.
2747 (Set_Implicit_With_From_Instantiation): Removed.
2748 (Set_Parent_With): New routine.
2749 * sinfo.ads: Update the documentation of attribute Implicit_With.
2750 Remove attribute Implicit_With_From_Instantiation along with
2751 occurrences in nodes. Add attribute Parent_With along with occurrences

2754 (Parent_With): New routine along with pragma Inline.
2755 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2756 (Set_Parent_With): New routine along with pragma Inline.
2758 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2760 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2761 entity when the enclosing construct is a body.
2763 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2765 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2766 Secondary_Stack_Size handling as a pragma is now generated for the
2767 corresponding aspect instead of an attribute. Pragma expression is
2768 relocated instead of evaluated. Discriminant of the corresponding
2769 record type is referenced rather than the type discriminant.
2770 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2771 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2772 * sem_ch13.adb (Analyze_One_Aspect): Transform
2773 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2774 because the attribute does not have visibility on a task type's
2775 discriminants when the type's definition is expanded.
2776 (Analyze_Attribute_Definition_Clause): Remove handling of
2777 Attribute_Secondary_Stack_Size.
2778 * snames.adb-tmpl, snames.ads-tmpl: Remove
2779 Attribute_Secondary_Stack_Size, no longer used.
2781 2018-01-11 Justin Squirek <squirek@adacore.com>

2785 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2787 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2788 individual action because the action may denote a complex expression,
2789 such as a case statement, which in turn may contain additional
2792 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2794 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2795 analysis on a copy of the expression with a copy of the index variable,
2796 because full expansion will rewrite construct into a loop with the
2797 original loop variable.
2798 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2799 expression is an iterated component association. Full analysis takes
2800 place when construct is rewritten as a loop.
2801 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2802 is not safe for in-place assignment.
2803 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2804 entity with no homonym and no other entity in the scope.
2806 2018-01-11 Justin Squirek <squirek@adacore.com>
2808 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2809 message to be printed on the pragma argument identifier.
2811 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2813 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2814 entity of the generated invariant procedure in order to construct a
2815 proper entity chain.
2817 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2819 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2822 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2824 * einfo.ads, einfo.adb (Activation_Record_Component,
2825 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2826 Allow E_Discriminant.
2828 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2830 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2831 for atomic access once the component size is taken into account and
2832 also do it if the component type is Atomic or Volatile_Full_Access.
2834 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2836 * gnatvsn.ads: Bump copyright year.
