491 comment about the memset case.
493 2018-05-30 Bob Duff <duff@adacore.com>
495 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
496 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
497 We need to analyze it as part of analyzing the block, so that if the
498 call to Element that initializes Elmt_Decl returns on the secondary
499 stack, the block will ss_mark/ss_release. This block is inside the
500 loop; we don't want to leak memory until the loop exits. The purpose
501 of analyzing Elmt_Decl first was to catch the error of modifying it,
502 which is illegal because it's a loop parameter. The above causes us to
503 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
504 it on the Element entity, so we end up with an E_Variable node with the
506 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
507 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
508 parameter not allowed" error if Is_Loop_Parameter.
509 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

526 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
527 a package body that is a compilation unit may contain blocks that
528 declare local subprograms. In Subprogram_Unnesting Mode such
529 subprograms must be handled as nested inside the (implicit) elaboration
530 procedure that executes that statement part. To handle properly uplevel
531 references we construct that subprogram explicitly, to contain blocks
532 and inner subprograms, The statement part of the compilation unit
533 becomes a call to this subprogram. This is only done if blocks are
534 present in the statement list of the body.

927 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
928 any; all callers changed. Handle N_Indexed_Component like
929 N_Attribute_Reference. Add N_Type_Conversion case.
930 (Visit_Node): Indexed references can be uplevel if the type isn't
932 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
933 been relocated, set first_named pointer in original node as well.

1086 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1088 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1089 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1090 into three distring cases rather than in one loop which attempts to
1091 handle all three cases. This rewrite eliminates an issue where the last
1092 frame of the stack cannot be freed, thus causing the memory range of a
1093 new frame to approach the overflow point of the memory index type.
1094 Since the overflow is logically treated as a
1095 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1096 (SS_Allocate_Static): New routine. The routine factorizes the static
1097 secondary stack-related code from the former SS_Allocate.

1109 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1110 is the proper body of a subunit, the cloned body must be inserted in
1111 the declarative list that contains the stub.

1150 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1151 Validate_Derived_Type_Instance, to verify that all interfaces
1152 implemented by the formal type are also implemented by the actual. The
1153 verification is complicated when an interface of the formal is declared
1154 in a generic unit and the actual is declared in an instance of it.
1155 There is currently no mechanism to relate an interface declared within
1156 a generic to the corresponding interface in an instance, so we must
1157 traverse the list of interfaces of the actual, looking for a name
1158 match, and verifying that that interface is declared in an instance.
1160 2018-05-25 Piotr Trojanek <trojanek@adacore.com>

2394 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2395 delegate the secondary stack management when there is no suitable
2396 transient context, and the transient scope was intended to manage the

2401 the comment on usage.

2536 either as an aspect specification or an explicit attribute
2537 specification clause, for the initialized object.
2538 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
2539 initial expressions in the case of a build-in-place call.
2541 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2543 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
2544 private (sub)type; refactor to avoid early return statement.
2545 (Not_Null_Range): Same as above.
2547 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2549 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
2550 concurrent, nor effectively volatile.
2551 * ghost.adb (Check_Ghost_Type): New routine.
2552 * ghost.ads (Check_Ghost_Type): New routine.
2553 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
2554 consider specific subsets of declarations.
2555 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
2556 replicated by Is_Declaration.
2557 * sem_util.ads (Is_Declaration): New parameter profile. Update the
2559 (Is_Declaration_Other_Than_Renaming): Removed.
2561 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2563 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
2564 as Part_Of consituents of single protected types are illegal when they
2565 take place inside a protected function.
2566 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
2568 (Is_Protected_Part_Of_Constituent): New routine.
2569 (Within_Function): New routine.
2571 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2573 Bump copyright notices to 2018.
2575 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2577 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
2580 2018-01-11 Justin Squirek <squirek@adacore.com>
2582 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2583 to make sure a given expression function is properly parenthesized.
2585 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2587 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2588 categorization of a subprogram body which does not complete a previous
2591 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2593 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2594 scope of package Ada is Standard.
2596 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2598 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2599 subcomponent of the current entity when building the body for a dynamic
2600 predicate function for a record with composite subcomponents.
2602 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

2610 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2611 Establish_Transient_Scope.
2612 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2613 management of the secondary stack to an enclosing scope if there is no
2614 suitable construct to wrap, and the transient scope was intended to
2615 manage the secondary stack.
2616 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2617 is a valid boundary for a transient expression which comes from the
2618 statements of the alternative, otherwise alternatives cannot be
2619 wrapped. Assignments of controlled objects which have controlled
2620 actions suppressed now stop the traversal as there is no point in
2621 looking for an enclosing construct. Add several N_xxx_Body choices to
2622 the termination conditions for completeness.
2623 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2624 and the associated comment on usage.
2625 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2626 Establish_Transient_Scope.
2627 (Add_Write_After): Update the call to Establish_Transient_Scope.
2628 * sem_res.adb (Check_Initialization_Call): Removed.
2629 (Resolve_Actuals): Account for additional cases where finalization
2630 actions are required by utilizing predicate Needs_Finalization rather
2632 (Resolve_Call): Type initialization procedures can now utilize
2633 transient scopes to manage the secondary stack, thus preventing leaks
2634 during initialization. Remove the previous kludgy algorithm which
2635 attempts to manage the secondary stack at the object creation site.
2637 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2639 * libgnat/g-soliop__qnx.ads: New.

2676 * gnat_rm.texi: Regenerate.
2678 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2680 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2681 formsl type corresponding to the actual fixed point type is private,
2682 because in this case there can be no suspicious arithmetic operations
2683 in the generic unless they reference a formal subprogram. Clarify
2686 2018-01-11 Javier Miranda <miranda@adacore.com>
2688 * exp_util.adb (Remove_Side_Effects): No action done for functions
2689 returning class-wide types since it requires generating code using
2690 'reference and the CCG target has no secondary stack.
2691 * gnat1drv.adb: Disable building static dispatch tables when generating

2702 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2704 2018-01-11 Bob Duff <duff@adacore.com>
2706 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2707 to match what the Libadalang-based version does.
2708 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2710 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2712 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2713 if it contains at least one component declaration employing a function
2714 call returning on the secondary stack.
2716 2018-01-11 Yannick Moy <moy@adacore.com>

2731 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2733 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2734 has a delayed aspect which must be processed at the point the type is
2735 frozen. This mimics what is done when the predicate is provided by a

2751 Default_Sec_Stack_Size.
2752 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2753 limit check so that the integer index does not overflow. Check the
2754 dynamic stack allocation does not cause the secondary stack pointer to
2756 (SS_Info): Align colons.
2757 (SS_Init): Cover the case when bootstraping with an old compiler that
2758 does not set Default_SS_Size.
2760 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2762 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2763 legality of an inherited operation that may require overriding, ignore
2764 primitive_wrappers that correspond to explicit operations that override
2765 an interface primitive.
2766 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2767 operation to which the class-wide expression applies is a protected op.
2768 with a primitive_wrapper, verify that the updated inherited expression
2769 does not contain an internal call to a protected function. This
2770 completes the implementation of AI12-0166.
2772 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2774 * ali.adb: Document the remaining letters available for ALI lines.
2775 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2776 * ali.ads: Update type With_Record. Field
2777 Implicit_With_From_Instantiation is no longer in use. Add field
2779 * csinfo.adb (CSinfo): Remove the setup for attribute
2780 Implicit_With_From_Instantiation.
2781 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2782 either implicitly or explicitly withed.
2783 (Is_Implicit_With_Clause): New routine.
2784 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2785 confusion with the with clause attribute by the same name.
2786 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2787 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2788 * sem_ch8.adb (Present_System_Aux): Code cleanup.

2791 (Implicit_With_On_Parent): Mark the with clause as generated for a
2793 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2794 instantiation are no longer marked as Implicit_With_From_Instantiation
2795 because they are already marked as implicit.
2796 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2797 which marks implicit with clauses as related to an instantiation.
2798 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2799 (Parent_With): New routine.
2800 (Set_Implicit_With_From_Instantiation): Removed.
2801 (Set_Parent_With): New routine.
2802 * sinfo.ads: Update the documentation of attribute Implicit_With.

2814 entity when the enclosing construct is a body.
2816 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2818 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2819 Secondary_Stack_Size handling as a pragma is now generated for the
2820 corresponding aspect instead of an attribute. Pragma expression is
2821 relocated instead of evaluated. Discriminant of the corresponding
2822 record type is referenced rather than the type discriminant.
2823 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2824 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2825 * sem_ch13.adb (Analyze_One_Aspect): Transform
2826 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2827 because the attribute does not have visibility on a task type's

2829 (Analyze_Attribute_Definition_Clause): Remove handling of
2830 Attribute_Secondary_Stack_Size.
2831 * snames.adb-tmpl, snames.ads-tmpl: Remove
2832 Attribute_Secondary_Stack_Size, no longer used.

2840 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2841 individual action because the action may denote a complex expression,
2842 such as a case statement, which in turn may contain additional
2845 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2847 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2848 analysis on a copy of the expression with a copy of the index variable,
2849 because full expansion will rewrite construct into a loop with the
2850 original loop variable.
2851 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2852 expression is an iterated component association. Full analysis takes
2853 place when construct is rewritten as a loop.
2854 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2855 is not safe for in-place assignment.
2856 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2857 entity with no homonym and no other entity in the scope.
2859 2018-01-11 Justin Squirek <squirek@adacore.com>
2861 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2862 message to be printed on the pragma argument identifier.

2866 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2867 entity of the generated invariant procedure in order to construct a
2868 proper entity chain.

2877 * einfo.ads, einfo.adb (Activation_Record_Component,
2878 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2879 Allow E_Discriminant.
2881 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2883 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2884 for atomic access once the component size is taken into account and
2885 also do it if the component type is Atomic or Volatile_Full_Access.
2887 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
