480 comment about the memset case.
482 2018-05-30 Bob Duff <duff@adacore.com>
484 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
485 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
486 We need to analyze it as part of analyzing the block, so that if the
487 call to Element that initializes Elmt_Decl returns on the secondary
488 stack, the block will ss_mark/ss_release. This block is inside the
489 loop; we don't want to leak memory until the loop exits. The purpose
490 of analyzing Elmt_Decl first was to catch the error of modifying it,
491 which is illegal because it's a loop parameter. The above causes us to
492 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
493 it on the Element entity, so we end up with an E_Variable node with the
495 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
496 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
497 parameter not allowed" error if Is_Loop_Parameter.
498 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

515 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
516 a package body that is a compilation unit may contain blocks that
517 declare local subprograms. In Subprogram_Unnesting Mode such
518 subprograms must be handled as nested inside the (implicit) elaboration
519 procedure that executes that statement part. To handle properly uplevel
520 references we construct that subprogram explicitly, to contain blocks
521 and inner subprograms, The statement part of the compilation unit
522 becomes a call to this subprogram. This is only done if blocks are
523 present in the statement list of the body.

834 of actual have uplevel references.
836 2018-05-28 Ed Schonberg <schonberg@adacore.com>

915 constant with private view so we take the address of that entity.
916 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
917 any; all callers changed. Handle N_Indexed_Component like
918 N_Attribute_Reference. Add N_Type_Conversion case.
919 (Visit_Node): Indexed references can be uplevel if the type isn't
921 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
922 been relocated, set first_named pointer in original node as well.

926 * exp_aggr.adb (Flatten): Copy tree of expression in a component
927 association with a range or a set of discrete choices, rather than

1075 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1077 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1078 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1079 into three distring cases rather than in one loop which attempts to
1080 handle all three cases. This rewrite eliminates an issue where the last
1081 frame of the stack cannot be freed, thus causing the memory range of a
1082 new frame to approach the overflow point of the memory index type.
1083 Since the overflow is logically treated as a
1084 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1085 (SS_Allocate_Static): New routine. The routine factorizes the static
1086 secondary stack-related code from the former SS_Allocate.

1096 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1097 is created when the proper body of the stub is analyzed.
1098 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1099 is the proper body of a subunit, the cloned body must be inserted in
1100 the declarative list that contains the stub.

1139 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1140 Validate_Derived_Type_Instance, to verify that all interfaces
1141 implemented by the formal type are also implemented by the actual. The
1142 verification is complicated when an interface of the formal is declared
1143 in a generic unit and the actual is declared in an instance of it.
1144 There is currently no mechanism to relate an interface declared within
1145 a generic to the corresponding interface in an instance, so we must
1146 traverse the list of interfaces of the actual, looking for a name
1147 match, and verifying that that interface is declared in an instance.

2383 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2384 delegate the secondary stack management when there is no suitable

2538 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
2539 concurrent, nor effectively volatile.
2540 * ghost.adb (Check_Ghost_Type): New routine.
2541 * ghost.ads (Check_Ghost_Type): New routine.
2542 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
2543 consider specific subsets of declarations.
2544 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
2545 replicated by Is_Declaration.
2546 * sem_util.ads (Is_Declaration): New parameter profile. Update the
2548 (Is_Declaration_Other_Than_Renaming): Removed.
2550 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2552 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
2553 as Part_Of consituents of single protected types are illegal when they
2554 take place inside a protected function.
2555 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
2557 (Is_Protected_Part_Of_Constituent): New routine.
2558 (Within_Function): New routine.

2562 Bump copyright notices to 2018.
2564 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2566 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
2569 2018-01-11 Justin Squirek <squirek@adacore.com>
2571 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2572 to make sure a given expression function is properly parenthesized.
2574 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2576 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2577 categorization of a subprogram body which does not complete a previous
2580 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2582 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2583 scope of package Ada is Standard.
2585 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2587 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2588 subcomponent of the current entity when building the body for a dynamic
2589 predicate function for a record with composite subcomponents.
2591 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

2599 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2600 Establish_Transient_Scope.
2601 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2602 management of the secondary stack to an enclosing scope if there is no
2603 suitable construct to wrap, and the transient scope was intended to
2604 manage the secondary stack.
2605 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2606 is a valid boundary for a transient expression which comes from the
2607 statements of the alternative, otherwise alternatives cannot be
2608 wrapped. Assignments of controlled objects which have controlled
2609 actions suppressed now stop the traversal as there is no point in
2610 looking for an enclosing construct. Add several N_xxx_Body choices to
2611 the termination conditions for completeness.
2612 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2613 and the associated comment on usage.
2614 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2615 Establish_Transient_Scope.
2616 (Add_Write_After): Update the call to Establish_Transient_Scope.
2617 * sem_res.adb (Check_Initialization_Call): Removed.
2618 (Resolve_Actuals): Account for additional cases where finalization
2619 actions are required by utilizing predicate Needs_Finalization rather
2621 (Resolve_Call): Type initialization procedures can now utilize
2622 transient scopes to manage the secondary stack, thus preventing leaks
2623 during initialization. Remove the previous kludgy algorithm which
2624 attempts to manage the secondary stack at the object creation site.
2626 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2628 * libgnat/g-soliop__qnx.ads: New.

2665 * gnat_rm.texi: Regenerate.
2667 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2669 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2670 formsl type corresponding to the actual fixed point type is private,
2671 because in this case there can be no suspicious arithmetic operations
2672 in the generic unless they reference a formal subprogram. Clarify
2675 2018-01-11 Javier Miranda <miranda@adacore.com>
2677 * exp_util.adb (Remove_Side_Effects): No action done for functions
2678 returning class-wide types since it requires generating code using
2679 'reference and the CCG target has no secondary stack.
2680 * gnat1drv.adb: Disable building static dispatch tables when generating

2691 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2693 2018-01-11 Bob Duff <duff@adacore.com>
2695 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2696 to match what the Libadalang-based version does.
2697 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2699 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2701 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2702 if it contains at least one component declaration employing a function
2703 call returning on the secondary stack.
2705 2018-01-11 Yannick Moy <moy@adacore.com>

2718 sem_res.adb, sem_util.adb: Minor reformatting.
2720 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2722 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2723 has a delayed aspect which must be processed at the point the type is
2724 frozen. This mimics what is done when the predicate is provided by a

2740 Default_Sec_Stack_Size.
2741 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2742 limit check so that the integer index does not overflow. Check the
2743 dynamic stack allocation does not cause the secondary stack pointer to
2745 (SS_Info): Align colons.
2746 (SS_Init): Cover the case when bootstraping with an old compiler that
2747 does not set Default_SS_Size.
2749 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2751 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2752 legality of an inherited operation that may require overriding, ignore
2753 primitive_wrappers that correspond to explicit operations that override
2754 an interface primitive.
2755 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2756 operation to which the class-wide expression applies is a protected op.
2757 with a primitive_wrapper, verify that the updated inherited expression
2758 does not contain an internal call to a protected function. This
2759 completes the implementation of AI12-0166.
2761 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2763 * ali.adb: Document the remaining letters available for ALI lines.
2764 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2765 * ali.ads: Update type With_Record. Field
2766 Implicit_With_From_Instantiation is no longer in use. Add field
2768 * csinfo.adb (CSinfo): Remove the setup for attribute
2769 Implicit_With_From_Instantiation.
2770 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2771 either implicitly or explicitly withed.
2772 (Is_Implicit_With_Clause): New routine.
2773 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2774 confusion with the with clause attribute by the same name.
2775 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2776 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2777 * sem_ch8.adb (Present_System_Aux): Code cleanup.

2780 (Implicit_With_On_Parent): Mark the with clause as generated for a
2782 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2783 instantiation are no longer marked as Implicit_With_From_Instantiation
2784 because they are already marked as implicit.
2785 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2786 which marks implicit with clauses as related to an instantiation.
2787 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2788 (Parent_With): New routine.
2789 (Set_Implicit_With_From_Instantiation): Removed.
2790 (Set_Parent_With): New routine.
2791 * sinfo.ads: Update the documentation of attribute Implicit_With.

2802 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2803 entity when the enclosing construct is a body.
2805 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2807 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2808 Secondary_Stack_Size handling as a pragma is now generated for the
2809 corresponding aspect instead of an attribute. Pragma expression is
2810 relocated instead of evaluated. Discriminant of the corresponding
2811 record type is referenced rather than the type discriminant.
2812 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2813 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2814 * sem_ch13.adb (Analyze_One_Aspect): Transform
2815 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2816 because the attribute does not have visibility on a task type's

2819 Attribute_Secondary_Stack_Size.
2820 * snames.adb-tmpl, snames.ads-tmpl: Remove
2821 Attribute_Secondary_Stack_Size, no longer used.

2829 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2830 individual action because the action may denote a complex expression,
2831 such as a case statement, which in turn may contain additional
2834 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2836 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2837 analysis on a copy of the expression with a copy of the index variable,
2838 because full expansion will rewrite construct into a loop with the
2839 original loop variable.
2840 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2841 expression is an iterated component association. Full analysis takes
2842 place when construct is rewritten as a loop.
2843 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2844 is not safe for in-place assignment.
2845 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2846 entity with no homonym and no other entity in the scope.
2848 2018-01-11 Justin Squirek <squirek@adacore.com>
2850 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2851 message to be printed on the pragma argument identifier.
2853 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2855 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2856 entity of the generated invariant procedure in order to construct a
2857 proper entity chain.

2866 * einfo.ads, einfo.adb (Activation_Record_Component,
2867 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2868 Allow E_Discriminant.
2870 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2872 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2873 for atomic access once the component size is taken into account and
2874 also do it if the component type is Atomic or Volatile_Full_Access.
2876 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
