454 comment about the memset case.
456 2018-05-30 Bob Duff <duff@adacore.com>
458 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
459 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
460 We need to analyze it as part of analyzing the block, so that if the
461 call to Element that initializes Elmt_Decl returns on the secondary
462 stack, the block will ss_mark/ss_release. This block is inside the
463 loop; we don't want to leak memory until the loop exits. The purpose
464 of analyzing Elmt_Decl first was to catch the error of modifying it,
465 which is illegal because it's a loop parameter. The above causes us to
466 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
467 it on the Element entity, so we end up with an E_Variable node with the
469 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
470 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
471 parameter not allowed" error if Is_Loop_Parameter.
472 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
473 trigger the call to Diagnose_Non_Variable_Lhs.

489 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
490 a package body that is a compilation unit may contain blocks that
491 declare local subprograms. In Subprogram_Unnesting Mode such
492 subprograms must be handled as nested inside the (implicit) elaboration
493 procedure that executes that statement part. To handle properly uplevel
494 references we construct that subprogram explicitly, to contain blocks
495 and inner subprograms, The statement part of the compilation unit
496 becomes a call to this subprogram. This is only done if blocks are
497 present in the statement list of the body.

558 2018-05-29 Javier Miranda <miranda@adacore.com>
560 * exp_ch4.adb (Expand_N_Op_Eq, Expand_Composite_Equality): Use the new
561 subprogram Inherits_From_Tagged_Full_View to identify more reliably
562 untagged private types completed with a derivation of an untagged
563 private whose full view is a tagged type.
564 * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
566 (Collect_Primitive_Operations): Handle untagged private types completed
567 with a derivation of an untagged private type whose full view is a
568 tagged type. In such case, collecting the list of primitives we may
569 find two equality primitives: one associated with the untagged private
570 and another associated with the ultimate tagged type (and we must
571 remove from the returned list this latter one).

630 * vx_crtbegin.inc: Use a consistent naming convention for the
631 registration/deregistration functions across RTP or kernel. Remove the
632 ctor/dtor attribute setting based on RTP/kernel, expect the optional

807 unconstrained array and the actual is constrained, check whether bounds
808 of actual have uplevel references.
810 2018-05-28 Ed Schonberg <schonberg@adacore.com>
812 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

833 value when converting a float value to a fixed-point value. This is
834 required for CCG because it handles fixed-point types by means of
835 unsigned integer type variables. The range check is now performed using
836 the integer value stored in this temporary.
838 2018-05-28 Yannick Moy <moy@adacore.com>
840 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
841 Length as valid non-interfering contexts for SPARK.

867 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
868 access-to-subprogram types, to indicate that an indirect call through
869 such a type requires an activation record when compiling for LLVM.
870 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
872 2018-05-28 Ed Schonberg <schonberg@adacore.com>
874 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
875 when bounds of fixed type are static, to remove some spuerfluous
876 implicit conversions and provide an accurate result when converting
877 back and forth between the fixed point type and a floating point type.
879 2018-05-28 Ed Schonberg <schonberg@adacore.com>

886 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
887 replaced, if any; all callers changed.
888 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
889 constant with private view so we take the address of that entity.
890 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
891 any; all callers changed. Handle N_Indexed_Component like
892 N_Attribute_Reference. Add N_Type_Conversion case.
893 (Visit_Node): Indexed references can be uplevel if the type isn't
895 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
896 been relocated, set first_named pointer in original node as well.

900 * exp_aggr.adb (Flatten): Copy tree of expression in a component
901 association with a range or a set of discrete choices, rather than
902 relocating the node. This avoids inconsistencies in the tree when
903 handling nested subprograms with uplevel references for LLVM.

969 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
970 includes a call to function to which it applies. This may mean an
971 omission of an attribute reference 'Result, in particular if the
972 function is pqrameterless.
974 2018-05-28 Justin Squirek <squirek@adacore.com>

1001 that the result will be either -infinite or +infinite.

1010 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1012 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1013 of a fixed point type and the parent is a multiplying operation,
1014 resolve the operand with its own type because the context will impose a
1015 resulting type on the result of the multiplication by means of
1016 approriate conversion.
1018 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1020 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1021 the in-place initialization aggregate created for pragmas
1022 Initialize_Scalars or Normalize_Scalars is performed with checks
1025 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1027 * exp_aggr.adb (Convert_To_Positional): Bump default for
1028 Max_Others_Replicate to 32. Update comments.
1029 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.

1049 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1051 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1052 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1053 into three distring cases rather than in one loop which attempts to
1054 handle all three cases. This rewrite eliminates an issue where the last
1055 frame of the stack cannot be freed, thus causing the memory range of a
1056 new frame to approach the overflow point of the memory index type.
1057 Since the overflow is logically treated as a

1117 in a generic unit and the actual is declared in an instance of it.
1118 There is currently no mechanism to relate an interface declared within
1119 a generic to the corresponding interface in an instance, so we must
1120 traverse the list of interfaces of the actual, looking for a name
1121 match, and verifying that that interface is declared in an instance.

1567 a constrained array component.
1568 * einfo.adb: Subprograms for Predicated_Parent.
1569 (Predicate_Function): Use new attribute.
1570 * exp_util.adb (Make_Predicate_Call): If the predicate function is not
1571 available for a subtype, retrieve it from the base type, which may have

1690 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
1691 iteration of an Ada2012 loop is performed to determine the type of the
1692 domain, but full analysis is performed once the loop is rewritten as a
1693 while-loop during expansion. The pre-analysis suppresses expansion; it
1694 must also suppress the generation of freeze nodes, which may otherwise
1695 appear in the wrong scope before rewritting.

2543 2018-01-11 Justin Squirek <squirek@adacore.com>
2545 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2546 to make sure a given expression function is properly parenthesized.
2548 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2550 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2551 categorization of a subprogram body which does not complete a previous

2561 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2562 subcomponent of the current entity when building the body for a dynamic
2563 predicate function for a record with composite subcomponents.
2565 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2567 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
2568 Establish_Transient_Scope.
2569 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.

2573 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2574 Establish_Transient_Scope.
2575 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2576 management of the secondary stack to an enclosing scope if there is no
2577 suitable construct to wrap, and the transient scope was intended to
2578 manage the secondary stack.
2579 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2580 is a valid boundary for a transient expression which comes from the
2581 statements of the alternative, otherwise alternatives cannot be
2582 wrapped. Assignments of controlled objects which have controlled
2583 actions suppressed now stop the traversal as there is no point in
2584 looking for an enclosing construct. Add several N_xxx_Body choices to
2585 the termination conditions for completeness.
2586 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2587 and the associated comment on usage.
2588 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2589 Establish_Transient_Scope.
2590 (Add_Write_After): Update the call to Establish_Transient_Scope.

2592 (Resolve_Actuals): Account for additional cases where finalization
2593 actions are required by utilizing predicate Needs_Finalization rather
2595 (Resolve_Call): Type initialization procedures can now utilize
2596 transient scopes to manage the secondary stack, thus preventing leaks
2597 during initialization. Remove the previous kludgy algorithm which
2598 attempts to manage the secondary stack at the object creation site.
2600 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

2643 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2644 formsl type corresponding to the actual fixed point type is private,
2645 because in this case there can be no suspicious arithmetic operations
2646 in the generic unless they reference a formal subprogram. Clarify
2649 2018-01-11 Javier Miranda <miranda@adacore.com>
2651 * exp_util.adb (Remove_Side_Effects): No action done for functions
2652 returning class-wide types since it requires generating code using
2653 'reference and the CCG target has no secondary stack.

2714 Default_Sec_Stack_Size.
2715 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2716 limit check so that the integer index does not overflow. Check the
2717 dynamic stack allocation does not cause the secondary stack pointer to
2719 (SS_Info): Align colons.
2720 (SS_Init): Cover the case when bootstraping with an old compiler that
2721 does not set Default_SS_Size.
2723 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2725 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2726 legality of an inherited operation that may require overriding, ignore
2727 primitive_wrappers that correspond to explicit operations that override
2728 an interface primitive.
2729 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2730 operation to which the class-wide expression applies is a protected op.
2731 with a primitive_wrapper, verify that the updated inherited expression
2732 does not contain an internal call to a protected function. This
2733 completes the implementation of AI12-0166.
2735 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2737 * ali.adb: Document the remaining letters available for ALI lines.
2738 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2739 * ali.ads: Update type With_Record. Field
2740 Implicit_With_From_Instantiation is no longer in use. Add field
2742 * csinfo.adb (CSinfo): Remove the setup for attribute
2743 Implicit_With_From_Instantiation.
2744 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2745 either implicitly or explicitly withed.
2746 (Is_Implicit_With_Clause): New routine.
2747 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2748 confusion with the with clause attribute by the same name.
2749 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2750 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2751 * sem_ch8.adb (Present_System_Aux): Code cleanup.

2754 (Implicit_With_On_Parent): Mark the with clause as generated for a
2756 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2757 instantiation are no longer marked as Implicit_With_From_Instantiation
2758 because they are already marked as implicit.
2759 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2760 which marks implicit with clauses as related to an instantiation.
2761 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2762 (Parent_With): New routine.
2763 (Set_Implicit_With_From_Instantiation): Removed.
2764 (Set_Parent_With): New routine.
2765 * sinfo.ads: Update the documentation of attribute Implicit_With.

2777 entity when the enclosing construct is a body.
2779 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2781 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2782 Secondary_Stack_Size handling as a pragma is now generated for the
2783 corresponding aspect instead of an attribute. Pragma expression is
2784 relocated instead of evaluated. Discriminant of the corresponding
2785 record type is referenced rather than the type discriminant.
2786 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2787 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2788 * sem_ch13.adb (Analyze_One_Aspect): Transform
2789 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2790 because the attribute does not have visibility on a task type's
2791 discriminants when the type's definition is expanded.
2792 (Analyze_Attribute_Definition_Clause): Remove handling of
2793 Attribute_Secondary_Stack_Size.
2794 * snames.adb-tmpl, snames.ads-tmpl: Remove
2795 Attribute_Secondary_Stack_Size, no longer used.

2803 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2804 individual action because the action may denote a complex expression,
2805 such as a case statement, which in turn may contain additional
2808 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2810 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2811 analysis on a copy of the expression with a copy of the index variable,
2812 because full expansion will rewrite construct into a loop with the
2813 original loop variable.
2814 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2815 expression is an iterated component association. Full analysis takes
2816 place when construct is rewritten as a loop.
2817 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2818 is not safe for in-place assignment.
2819 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2820 entity with no homonym and no other entity in the scope.
2822 2018-01-11 Justin Squirek <squirek@adacore.com>
2824 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2825 message to be printed on the pragma argument identifier.
2827 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2829 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2830 entity of the generated invariant procedure in order to construct a
2831 proper entity chain.

2842 Allow E_Discriminant.
2844 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2846 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2847 for atomic access once the component size is taken into account and
2848 also do it if the component type is Atomic or Volatile_Full_Access.
2850 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
