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

525 target compiler may provide a wider range.

532 2018-05-30 Ed Schonberg <schonberg@adacore.com>
534 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
535 a package body that is a compilation unit may contain blocks that
536 declare local subprograms. In Subprogram_Unnesting Mode such
537 subprograms must be handled as nested inside the (implicit) elaboration
538 procedure that executes that statement part. To handle properly uplevel
539 references we construct that subprogram explicitly, to contain blocks
540 and inner subprograms, The statement part of the compilation unit

853 of actual have uplevel references.
855 2018-05-28 Ed Schonberg <schonberg@adacore.com>

935 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
936 any; all callers changed. Handle N_Indexed_Component like
937 N_Attribute_Reference. Add N_Type_Conversion case.
938 (Visit_Node): Indexed references can be uplevel if the type isn't
940 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

1094 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1096 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1097 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1098 into three distring cases rather than in one loop which attempts to
1099 handle all three cases. This rewrite eliminates an issue where the last
1100 frame of the stack cannot be freed, thus causing the memory range of a
1101 new frame to approach the overflow point of the memory index type.
1102 Since the overflow is logically treated as a
1103 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1104 (SS_Allocate_Static): New routine. The routine factorizes the static
1105 secondary stack-related code from the former SS_Allocate.

1117 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1118 is the proper body of a subunit, the cloned body must be inserted in
1119 the declarative list that contains the stub.

1158 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1159 Validate_Derived_Type_Instance, to verify that all interfaces
1160 implemented by the formal type are also implemented by the actual. The
1161 verification is complicated when an interface of the formal is declared
1162 in a generic unit and the actual is declared in an instance of it.
1163 There is currently no mechanism to relate an interface declared within
1164 a generic to the corresponding interface in an instance, so we must
1165 traverse the list of interfaces of the actual, looking for a name
1166 match, and verifying that that interface is declared in an instance.

1736 iteration of an Ada2012 loop is performed to determine the type of the

2402 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2403 delegate the secondary stack management when there is no suitable

2536 result of Get_Simple_Init_Value and pass the source location of the
2537 object declaration's object_definition.
2539 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2541 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
2542 properly object declarations with initializations that are
2543 build-in-place function calls, when there is an address specification,
2544 either as an aspect specification or an explicit attribute
2545 specification clause, for the initialized object.
2546 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
2547 initial expressions in the case of a build-in-place call.
2549 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2551 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
2552 private (sub)type; refactor to avoid early return statement.
2553 (Not_Null_Range): Same as above.
2555 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2557 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
2558 concurrent, nor effectively volatile.
2559 * ghost.adb (Check_Ghost_Type): New routine.
2560 * ghost.ads (Check_Ghost_Type): New routine.
2561 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
2562 consider specific subsets of declarations.
2563 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
2564 replicated by Is_Declaration.
2565 * sem_util.ads (Is_Declaration): New parameter profile. Update the
2567 (Is_Declaration_Other_Than_Renaming): Removed.
2569 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2571 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
2572 as Part_Of consituents of single protected types are illegal when they
2573 take place inside a protected function.
2574 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
2576 (Is_Protected_Part_Of_Constituent): New routine.
2577 (Within_Function): New routine.

2581 Bump copyright notices to 2018.
2583 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2585 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
2588 2018-01-11 Justin Squirek <squirek@adacore.com>
2590 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2591 to make sure a given expression function is properly parenthesized.
2593 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2595 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2596 categorization of a subprogram body which does not complete a previous
2599 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2601 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2602 scope of package Ada is Standard.
2604 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2606 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2607 subcomponent of the current entity when building the body for a dynamic
2608 predicate function for a record with composite subcomponents.
2610 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

2618 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2619 Establish_Transient_Scope.
2620 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2621 management of the secondary stack to an enclosing scope if there is no
2622 suitable construct to wrap, and the transient scope was intended to
2623 manage the secondary stack.
2624 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2625 is a valid boundary for a transient expression which comes from the
2626 statements of the alternative, otherwise alternatives cannot be
2627 wrapped. Assignments of controlled objects which have controlled
2628 actions suppressed now stop the traversal as there is no point in
2629 looking for an enclosing construct. Add several N_xxx_Body choices to
2630 the termination conditions for completeness.
2631 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2632 and the associated comment on usage.
2633 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2634 Establish_Transient_Scope.
2635 (Add_Write_After): Update the call to Establish_Transient_Scope.
2636 * sem_res.adb (Check_Initialization_Call): Removed.
2637 (Resolve_Actuals): Account for additional cases where finalization
2638 actions are required by utilizing predicate Needs_Finalization rather
2640 (Resolve_Call): Type initialization procedures can now utilize
2641 transient scopes to manage the secondary stack, thus preventing leaks
2642 during initialization. Remove the previous kludgy algorithm which
2643 attempts to manage the secondary stack at the object creation site.
2645 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2647 * libgnat/g-soliop__qnx.ads: New.

2684 * gnat_rm.texi: Regenerate.
2686 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2688 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2689 formsl type corresponding to the actual fixed point type is private,
2690 because in this case there can be no suspicious arithmetic operations
2691 in the generic unless they reference a formal subprogram. Clarify
2694 2018-01-11 Javier Miranda <miranda@adacore.com>
2696 * exp_util.adb (Remove_Side_Effects): No action done for functions
2697 returning class-wide types since it requires generating code using
2698 'reference and the CCG target has no secondary stack.
2699 * gnat1drv.adb: Disable building static dispatch tables when generating

2712 2018-01-11 Bob Duff <duff@adacore.com>
2714 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2715 to match what the Libadalang-based version does.
2716 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2718 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2720 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2721 if it contains at least one component declaration employing a function
2722 call returning on the secondary stack.
2724 2018-01-11 Yannick Moy <moy@adacore.com>

2741 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2742 has a delayed aspect which must be processed at the point the type is
2743 frozen. This mimics what is done when the predicate is provided by a

2759 Default_Sec_Stack_Size.
2760 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2761 limit check so that the integer index does not overflow. Check the
2762 dynamic stack allocation does not cause the secondary stack pointer to
2764 (SS_Info): Align colons.
2765 (SS_Init): Cover the case when bootstraping with an old compiler that
2766 does not set Default_SS_Size.
2768 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2770 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2771 legality of an inherited operation that may require overriding, ignore
2772 primitive_wrappers that correspond to explicit operations that override
2773 an interface primitive.
2774 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2775 operation to which the class-wide expression applies is a protected op.
2776 with a primitive_wrapper, verify that the updated inherited expression
2777 does not contain an internal call to a protected function. This
2778 completes the implementation of AI12-0166.
2780 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2782 * ali.adb: Document the remaining letters available for ALI lines.
2783 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2784 * ali.ads: Update type With_Record. Field
2785 Implicit_With_From_Instantiation is no longer in use. Add field
2787 * csinfo.adb (CSinfo): Remove the setup for attribute
2788 Implicit_With_From_Instantiation.
2789 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2790 either implicitly or explicitly withed.
2791 (Is_Implicit_With_Clause): New routine.
2792 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2793 confusion with the with clause attribute by the same name.
2794 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2795 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2796 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2797 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2799 (Implicit_With_On_Parent): Mark the with clause as generated for a
2801 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2802 instantiation are no longer marked as Implicit_With_From_Instantiation
2803 because they are already marked as implicit.
2804 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2805 which marks implicit with clauses as related to an instantiation.
2806 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2807 (Parent_With): New routine.
2808 (Set_Implicit_With_From_Instantiation): Removed.
2809 (Set_Parent_With): New routine.
2810 * sinfo.ads: Update the documentation of attribute Implicit_With.

2822 entity when the enclosing construct is a body.
2824 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2826 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2827 Secondary_Stack_Size handling as a pragma is now generated for the
2828 corresponding aspect instead of an attribute. Pragma expression is
2829 relocated instead of evaluated. Discriminant of the corresponding
2830 record type is referenced rather than the type discriminant.
2831 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2832 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2833 * sem_ch13.adb (Analyze_One_Aspect): Transform
2834 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2835 because the attribute does not have visibility on a task type's
2836 discriminants when the type's definition is expanded.
2837 (Analyze_Attribute_Definition_Clause): Remove handling of
2838 Attribute_Secondary_Stack_Size.
2839 * snames.adb-tmpl, snames.ads-tmpl: Remove

2848 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2849 individual action because the action may denote a complex expression,
2850 such as a case statement, which in turn may contain additional
2853 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2855 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2856 analysis on a copy of the expression with a copy of the index variable,
2857 because full expansion will rewrite construct into a loop with the
2858 original loop variable.
2859 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2860 expression is an iterated component association. Full analysis takes
2861 place when construct is rewritten as a loop.
2862 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2863 is not safe for in-place assignment.
2864 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2865 entity with no homonym and no other entity in the scope.
2867 2018-01-11 Justin Squirek <squirek@adacore.com>

2875 entity of the generated invariant procedure in order to construct a
2876 proper entity chain.

2887 Allow E_Discriminant.
2889 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2891 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2892 for atomic access once the component size is taken into account and
2893 also do it if the component type is Atomic or Volatile_Full_Access.
2895 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
