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

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

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

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

772 unconstrained array and the actual is constrained, check whether bounds
773 of actual have uplevel references.
775 2018-05-28 Ed Schonberg <schonberg@adacore.com>
777 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

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

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

837 2018-05-28 Ed Schonberg <schonberg@adacore.com>
839 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
840 when bounds of fixed type are static, to remove some spuerfluous
841 implicit conversions and provide an accurate result when converting
842 back and forth between the fixed point type and a floating point type.
844 2018-05-28 Ed Schonberg <schonberg@adacore.com>

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

882 unnecessary use of 'Unrestricted_Access.

934 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
935 includes a call to function to which it applies. This may mean an
936 omission of an attribute reference 'Result, in particular if the
937 function is pqrameterless.
939 2018-05-28 Justin Squirek <squirek@adacore.com>

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

966 that the result will be either -infinite or +infinite.
968 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
970 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
971 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
972 Expand range of type to match the address space of the target.
973 (Task_Storage_Size): Remove unused type.
975 2018-05-25 Ed Schonberg <schonberg@adacore.com>
977 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
978 of a fixed point type and the parent is a multiplying operation,
979 resolve the operand with its own type because the context will impose a
980 resulting type on the result of the multiplication by means of
981 approriate conversion.
983 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
985 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
986 the in-place initialization aggregate created for pragmas
987 Initialize_Scalars or Normalize_Scalars is performed with checks
990 2018-05-25 Arnaud Charlet <charlet@adacore.com>
992 * exp_aggr.adb (Convert_To_Positional): Bump default for
993 Max_Others_Replicate to 32. Update comments.
994 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
995 (No_File_Info_Cache): Initialize separately.

1014 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1016 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1017 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1018 into three distring cases rather than in one loop which attempts to
1019 handle all three cases. This rewrite eliminates an issue where the last
1020 frame of the stack cannot be freed, thus causing the memory range of a
1021 new frame to approach the overflow point of the memory index type.
1022 Since the overflow is logically treated as a
1023 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1024 (SS_Allocate_Static): New routine. The routine factorizes the static
1025 secondary stack-related code from the former SS_Allocate.
1027 2018-05-25 Sergey Rybin <rybin@adacore.com>
1029 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

1034 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1035 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1036 is created when the proper body of the stub is analyzed.
1037 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1038 is the proper body of a subunit, the cloned body must be inserted in
1039 the declarative list that contains the stub.
1041 2018-05-25 Justin Squirek <squirek@adacore.com>
1043 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1044 generate code for 6.5(8-10) so that we don't get an assertion error
1045 when dealing with an incomplete return type.
1047 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1050 carrying very large strings.

1078 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1079 Validate_Derived_Type_Instance, to verify that all interfaces
1080 implemented by the formal type are also implemented by the actual. The
1081 verification is complicated when an interface of the formal is declared
1082 in a generic unit and the actual is declared in an instance of it.
1083 There is currently no mechanism to relate an interface declared within
1084 a generic to the corresponding interface in an instance, so we must
1085 traverse the list of interfaces of the actual, looking for a name
1086 match, and verifying that that interface is declared in an instance.

2536 * exp_ch6.adb (Expand_Call_Helper): Update the call to
2537 Establish_Transient_Scope.
2538 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2539 Establish_Transient_Scope.
2540 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2541 management of the secondary stack to an enclosing scope if there is no
2542 suitable construct to wrap, and the transient scope was intended to
2543 manage the secondary stack.
2544 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2545 is a valid boundary for a transient expression which comes from the
2546 statements of the alternative, otherwise alternatives cannot be
2547 wrapped. Assignments of controlled objects which have controlled
2548 actions suppressed now stop the traversal as there is no point in
2549 looking for an enclosing construct. Add several N_xxx_Body choices to
2550 the termination conditions for completeness.
2551 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2552 and the associated comment on usage.
2553 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2554 Establish_Transient_Scope.
2555 (Add_Write_After): Update the call to Establish_Transient_Scope.
2556 * sem_res.adb (Check_Initialization_Call): Removed.
2557 (Resolve_Actuals): Account for additional cases where finalization
2558 actions are required by utilizing predicate Needs_Finalization rather
2560 (Resolve_Call): Type initialization procedures can now utilize
2561 transient scopes to manage the secondary stack, thus preventing leaks
2562 during initialization. Remove the previous kludgy algorithm which
2563 attempts to manage the secondary stack at the object creation site.
2565 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2567 * libgnat/g-soliop__qnx.ads: New.

2604 * gnat_rm.texi: Regenerate.
2606 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2608 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2609 formsl type corresponding to the actual fixed point type is private,
2610 because in this case there can be no suspicious arithmetic operations
2611 in the generic unless they reference a formal subprogram. Clarify
2614 2018-01-11 Javier Miranda <miranda@adacore.com>
2616 * exp_util.adb (Remove_Side_Effects): No action done for functions
2617 returning class-wide types since it requires generating code using
2618 'reference and the CCG target has no secondary stack.
2619 * gnat1drv.adb: Disable building static dispatch tables when generating
2622 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

2626 (File_Type): Add Default_Initial_Condition aspect.
2628 2018-01-11 Pascal Obry <obry@adacore.com>
2630 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2632 2018-01-11 Bob Duff <duff@adacore.com>
2634 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2635 to match what the Libadalang-based version does.
2636 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2638 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2640 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2641 if it contains at least one component declaration employing a function
2642 call returning on the secondary stack.
2644 2018-01-11 Yannick Moy <moy@adacore.com>
2646 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2647 Update description of restriction SPARK_05 with SPARK 2014.

2656 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2657 sem_res.adb, sem_util.adb: Minor reformatting.
2659 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2661 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2662 has a delayed aspect which must be processed at the point the type is
2663 frozen. This mimics what is done when the predicate is provided by a
2666 2018-01-11 Doug Rupp <rupp@adacore.com>
2668 * init.c (vxworks): Add macro checks for __aarch64__.
2670 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2672 * exp_util.adb (Add_Failure_Expression): New routine.

2674 * sem_util.adb (Is_Current_Instance): Code cleanup.
2676 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2678 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2679 Default_Sec_Stack_Size.
2680 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2681 limit check so that the integer index does not overflow. Check the
2682 dynamic stack allocation does not cause the secondary stack pointer to
2684 (SS_Info): Align colons.
2685 (SS_Init): Cover the case when bootstraping with an old compiler that
2686 does not set Default_SS_Size.
2688 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2690 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2691 legality of an inherited operation that may require overriding, ignore
2692 primitive_wrappers that correspond to explicit operations that override
2693 an interface primitive.
2694 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2695 operation to which the class-wide expression applies is a protected op.
2696 with a primitive_wrapper, verify that the updated inherited expression
2697 does not contain an internal call to a protected function. This
2698 completes the implementation of AI12-0166.
2700 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2702 * ali.adb: Document the remaining letters available for ALI lines.
2703 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2704 * ali.ads: Update type With_Record. Field
2705 Implicit_With_From_Instantiation is no longer in use. Add field
2707 * csinfo.adb (CSinfo): Remove the setup for attribute
2708 Implicit_With_From_Instantiation.
2709 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2710 either implicitly or explicitly withed.
2711 (Is_Implicit_With_Clause): New routine.
2712 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2713 confusion with the with clause attribute by the same name.
2714 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2715 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2716 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2717 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2719 (Implicit_With_On_Parent): Mark the with clause as generated for a
2721 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2722 instantiation are no longer marked as Implicit_With_From_Instantiation
2723 because they are already marked as implicit.
2724 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2725 which marks implicit with clauses as related to an instantiation.
2726 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2727 (Parent_With): New routine.
2728 (Set_Implicit_With_From_Instantiation): Removed.
2729 (Set_Parent_With): New routine.
2730 * sinfo.ads: Update the documentation of attribute Implicit_With.
2731 Remove attribute Implicit_With_From_Instantiation along with
2732 occurrences in nodes. Add attribute Parent_With along with occurrences

2739 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2741 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2742 entity when the enclosing construct is a body.
2744 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2746 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2747 Secondary_Stack_Size handling as a pragma is now generated for the
2748 corresponding aspect instead of an attribute. Pragma expression is
2749 relocated instead of evaluated. Discriminant of the corresponding
2750 record type is referenced rather than the type discriminant.
2751 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2752 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2753 * sem_ch13.adb (Analyze_One_Aspect): Transform
2754 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2755 because the attribute does not have visibility on a task type's
2756 discriminants when the type's definition is expanded.
2757 (Analyze_Attribute_Definition_Clause): Remove handling of
2758 Attribute_Secondary_Stack_Size.
2759 * snames.adb-tmpl, snames.ads-tmpl: Remove
2760 Attribute_Secondary_Stack_Size, no longer used.

2766 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2768 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2769 individual action because the action may denote a complex expression,
2770 such as a case statement, which in turn may contain additional
2773 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2775 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2776 analysis on a copy of the expression with a copy of the index variable,
2777 because full expansion will rewrite construct into a loop with the
2778 original loop variable.
2779 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2780 expression is an iterated component association. Full analysis takes
2781 place when construct is rewritten as a loop.
2782 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2783 is not safe for in-place assignment.
2784 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2785 entity with no homonym and no other entity in the scope.
2787 2018-01-11 Justin Squirek <squirek@adacore.com>
2789 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2790 message to be printed on the pragma argument identifier.
2792 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2794 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2795 entity of the generated invariant procedure in order to construct a
2796 proper entity chain.
2798 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2800 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in

2805 * einfo.ads, einfo.adb (Activation_Record_Component,
2806 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2807 Allow E_Discriminant.
2809 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2811 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2812 for atomic access once the component size is taken into account and
2813 also do it if the component type is Atomic or Volatile_Full_Access.
2815 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2817 * gnatvsn.ads: Bump copyright year.
