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

502 2018-05-30 Ed Schonberg <schonberg@adacore.com>
504 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
505 a package body that is a compilation unit may contain blocks that
506 declare local subprograms. In Subprogram_Unnesting Mode such
507 subprograms must be handled as nested inside the (implicit) elaboration
508 procedure that executes that statement part. To handle properly uplevel
509 references we construct that subprogram explicitly, to contain blocks
510 and inner subprograms, The statement part of the compilation unit
511 becomes a call to this subprogram. This is only done if blocks are
512 present in the statement list of the body.

823 of actual have uplevel references.
825 2018-05-28 Ed Schonberg <schonberg@adacore.com>

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

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

1064 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1066 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1067 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1068 into three distring cases rather than in one loop which attempts to
1069 handle all three cases. This rewrite eliminates an issue where the last
1070 frame of the stack cannot be freed, thus causing the memory range of a
1071 new frame to approach the overflow point of the memory index type.
1072 Since the overflow is logically treated as a
1073 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1074 (SS_Allocate_Static): New routine. The routine factorizes the static
1075 secondary stack-related code from the former SS_Allocate.

1087 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1088 is the proper body of a subunit, the cloned body must be inserted in
1089 the declarative list that contains the stub.

1128 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1129 Validate_Derived_Type_Instance, to verify that all interfaces
1130 implemented by the formal type are also implemented by the actual. The
1131 verification is complicated when an interface of the formal is declared
1132 in a generic unit and the actual is declared in an instance of it.
1133 There is currently no mechanism to relate an interface declared within
1134 a generic to the corresponding interface in an instance, so we must
1135 traverse the list of interfaces of the actual, looking for a name
1136 match, and verifying that that interface is declared in an instance.

2372 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2373 delegate the secondary stack management when there is no suitable

2534 replicated by Is_Declaration.
2535 * sem_util.ads (Is_Declaration): New parameter profile. Update the
2537 (Is_Declaration_Other_Than_Renaming): Removed.
2539 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2541 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
2542 as Part_Of consituents of single protected types are illegal when they
2543 take place inside a protected function.
2544 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
2546 (Is_Protected_Part_Of_Constituent): New routine.
2547 (Within_Function): New routine.

2551 Bump copyright notices to 2018.
2553 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2555 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
2558 2018-01-11 Justin Squirek <squirek@adacore.com>
2560 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2561 to make sure a given expression function is properly parenthesized.
2563 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2565 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2566 categorization of a subprogram body which does not complete a previous
2569 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2571 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2572 scope of package Ada is Standard.
2574 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2576 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2577 subcomponent of the current entity when building the body for a dynamic
2578 predicate function for a record with composite subcomponents.
2580 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2582 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
2583 Establish_Transient_Scope.

2588 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2589 Establish_Transient_Scope.
2590 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2591 management of the secondary stack to an enclosing scope if there is no
2592 suitable construct to wrap, and the transient scope was intended to
2593 manage the secondary stack.
2594 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2595 is a valid boundary for a transient expression which comes from the
2596 statements of the alternative, otherwise alternatives cannot be
2597 wrapped. Assignments of controlled objects which have controlled
2598 actions suppressed now stop the traversal as there is no point in
2599 looking for an enclosing construct. Add several N_xxx_Body choices to
2600 the termination conditions for completeness.
2601 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2602 and the associated comment on usage.
2603 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2604 Establish_Transient_Scope.
2605 (Add_Write_After): Update the call to Establish_Transient_Scope.
2606 * sem_res.adb (Check_Initialization_Call): Removed.
2607 (Resolve_Actuals): Account for additional cases where finalization
2608 actions are required by utilizing predicate Needs_Finalization rather
2610 (Resolve_Call): Type initialization procedures can now utilize
2611 transient scopes to manage the secondary stack, thus preventing leaks
2612 during initialization. Remove the previous kludgy algorithm which
2613 attempts to manage the secondary stack at the object creation site.
2615 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2617 * libgnat/g-soliop__qnx.ads: New.

2654 * gnat_rm.texi: Regenerate.
2656 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2658 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2659 formsl type corresponding to the actual fixed point type is private,
2660 because in this case there can be no suspicious arithmetic operations
2661 in the generic unless they reference a formal subprogram. Clarify
2664 2018-01-11 Javier Miranda <miranda@adacore.com>
2666 * exp_util.adb (Remove_Side_Effects): No action done for functions
2667 returning class-wide types since it requires generating code using
2668 'reference and the CCG target has no secondary stack.
2669 * gnat1drv.adb: Disable building static dispatch tables when generating

2680 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2682 2018-01-11 Bob Duff <duff@adacore.com>
2684 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2685 to match what the Libadalang-based version does.
2686 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2688 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2690 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2691 if it contains at least one component declaration employing a function
2692 call returning on the secondary stack.
2694 2018-01-11 Yannick Moy <moy@adacore.com>
2696 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

2707 sem_res.adb, sem_util.adb: Minor reformatting.
2709 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2711 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2712 has a delayed aspect which must be processed at the point the type is
2713 frozen. This mimics what is done when the predicate is provided by a

2729 Default_Sec_Stack_Size.
2730 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2731 limit check so that the integer index does not overflow. Check the
2732 dynamic stack allocation does not cause the secondary stack pointer to
2734 (SS_Info): Align colons.
2735 (SS_Init): Cover the case when bootstraping with an old compiler that
2736 does not set Default_SS_Size.
2738 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2740 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2741 legality of an inherited operation that may require overriding, ignore
2742 primitive_wrappers that correspond to explicit operations that override
2743 an interface primitive.
2744 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2745 operation to which the class-wide expression applies is a protected op.
2746 with a primitive_wrapper, verify that the updated inherited expression
2747 does not contain an internal call to a protected function. This
2748 completes the implementation of AI12-0166.
2750 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2752 * ali.adb: Document the remaining letters available for ALI lines.
2753 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2754 * ali.ads: Update type With_Record. Field
2755 Implicit_With_From_Instantiation is no longer in use. Add field
2757 * csinfo.adb (CSinfo): Remove the setup for attribute
2758 Implicit_With_From_Instantiation.
2759 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2760 either implicitly or explicitly withed.
2761 (Is_Implicit_With_Clause): New routine.
2762 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2763 confusion with the with clause attribute by the same name.
2764 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2765 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2766 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2767 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2769 (Implicit_With_On_Parent): Mark the with clause as generated for a
2771 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2772 instantiation are no longer marked as Implicit_With_From_Instantiation
2773 because they are already marked as implicit.
2774 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2775 which marks implicit with clauses as related to an instantiation.
2776 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2777 (Parent_With): New routine.
2778 (Set_Implicit_With_From_Instantiation): Removed.
2779 (Set_Parent_With): New routine.
2780 * sinfo.ads: Update the documentation of attribute Implicit_With.
2781 Remove attribute Implicit_With_From_Instantiation along with

2792 entity when the enclosing construct is a body.
2794 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2796 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2797 Secondary_Stack_Size handling as a pragma is now generated for the
2798 corresponding aspect instead of an attribute. Pragma expression is
2799 relocated instead of evaluated. Discriminant of the corresponding
2800 record type is referenced rather than the type discriminant.
2801 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2802 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2803 * sem_ch13.adb (Analyze_One_Aspect): Transform
2804 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2805 because the attribute does not have visibility on a task type's
2806 discriminants when the type's definition is expanded.
2807 (Analyze_Attribute_Definition_Clause): Remove handling of
2808 Attribute_Secondary_Stack_Size.
2809 * snames.adb-tmpl, snames.ads-tmpl: Remove
2810 Attribute_Secondary_Stack_Size, no longer used.

2818 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2819 individual action because the action may denote a complex expression,
2820 such as a case statement, which in turn may contain additional
2823 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2825 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2826 analysis on a copy of the expression with a copy of the index variable,
2827 because full expansion will rewrite construct into a loop with the
2828 original loop variable.
2829 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2830 expression is an iterated component association. Full analysis takes
2831 place when construct is rewritten as a loop.
2832 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2833 is not safe for in-place assignment.
2834 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2835 entity with no homonym and no other entity in the scope.
2837 2018-01-11 Justin Squirek <squirek@adacore.com>
2839 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2840 message to be printed on the pragma argument identifier.
2842 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2844 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2845 entity of the generated invariant procedure in order to construct a
2846 proper entity chain.

2855 * einfo.ads, einfo.adb (Activation_Record_Component,
2856 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2857 Allow E_Discriminant.
2859 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2861 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2862 for atomic access once the component size is taken into account and
2863 also do it if the component type is Atomic or Volatile_Full_Access.
2865 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
