324 comment about the memset case.
326 2018-05-30 Bob Duff <duff@adacore.com>
328 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
329 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
330 We need to analyze it as part of analyzing the block, so that if the
331 call to Element that initializes Elmt_Decl returns on the secondary
332 stack, the block will ss_mark/ss_release. This block is inside the
333 loop; we don't want to leak memory until the loop exits. The purpose
334 of analyzing Elmt_Decl first was to catch the error of modifying it,
335 which is illegal because it's a loop parameter. The above causes us to
336 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
337 it on the Element entity, so we end up with an E_Variable node with the
339 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
340 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
341 parameter not allowed" error if Is_Loop_Parameter.
342 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
343 trigger the call to Diagnose_Non_Variable_Lhs.

357 2018-05-30 Ed Schonberg <schonberg@adacore.com>
359 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
360 a package body that is a compilation unit may contain blocks that
361 declare local subprograms. In Subprogram_Unnesting Mode such
362 subprograms must be handled as nested inside the (implicit) elaboration
363 procedure that executes that statement part. To handle properly uplevel
364 references we construct that subprogram explicitly, to contain blocks
365 and inner subprograms, The statement part of the compilation unit
366 becomes a call to this subprogram. This is only done if blocks are
367 present in the statement list of the body.
369 2018-05-30 Bob Duff <duff@adacore.com>

379 for subprogram instantiations to enter callable entity into Subp table.

703 value when converting a float value to a fixed-point value. This is
704 required for CCG because it handles fixed-point types by means of

742 2018-05-28 Ed Schonberg <schonberg@adacore.com>
744 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
745 when bounds of fixed type are static, to remove some spuerfluous
746 implicit conversions and provide an accurate result when converting
747 back and forth between the fixed point type and a floating point type.

754 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
756 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
757 replaced, if any; all callers changed.
758 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
759 constant with private view so we take the address of that entity.
760 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
761 any; all callers changed. Handle N_Indexed_Component like
762 N_Attribute_Reference. Add N_Type_Conversion case.
763 (Visit_Node): Indexed references can be uplevel if the type isn't
765 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
766 been relocated, set first_named pointer in original node as well.
768 2018-05-28 Ed Schonberg <schonberg@adacore.com>
770 * exp_aggr.adb (Flatten): Copy tree of expression in a component
771 association with a range or a set of discrete choices, rather than
772 relocating the node. This avoids inconsistencies in the tree when
773 handling nested subprograms with uplevel references for LLVM.

860 (List_Entities): Do not output the linker section for record types,
861 array types and variables.

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

880 2018-05-25 Ed Schonberg <schonberg@adacore.com>
882 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
883 of a fixed point type and the parent is a multiplying operation,
884 resolve the operand with its own type because the context will impose a
885 resulting type on the result of the multiplication by means of
886 approriate conversion.
888 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
890 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of

892 Initialize_Scalars or Normalize_Scalars is performed with checks

897 * exp_aggr.adb (Convert_To_Positional): Bump default for
898 Max_Others_Replicate to 32. Update comments.

921 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
922 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
923 into three distring cases rather than in one loop which attempts to
924 handle all three cases. This rewrite eliminates an issue where the last
925 frame of the stack cannot be freed, thus causing the memory range of a
926 new frame to approach the overflow point of the memory index type.
927 Since the overflow is logically treated as a
928 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
929 (SS_Allocate_Static): New routine. The routine factorizes the static
930 secondary stack-related code from the former SS_Allocate.
932 2018-05-25 Sergey Rybin <rybin@adacore.com>

939 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
940 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
941 is created when the proper body of the stub is analyzed.
942 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
943 is the proper body of a subunit, the cloned body must be inserted in
944 the declarative list that contains the stub.
946 2018-05-25 Justin Squirek <squirek@adacore.com>
948 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
949 generate code for 6.5(8-10) so that we don't get an assertion error
950 when dealing with an incomplete return type.
952 2018-05-25 Arnaud Charlet <charlet@adacore.com>

983 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
984 Validate_Derived_Type_Instance, to verify that all interfaces
985 implemented by the formal type are also implemented by the actual. The
986 verification is complicated when an interface of the formal is declared
987 in a generic unit and the actual is declared in an instance of it.
988 There is currently no mechanism to relate an interface declared within
989 a generic to the corresponding interface in an instance, so we must
990 traverse the list of interfaces of the actual, looking for a name
991 match, and verifying that that interface is declared in an instance.
993 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
995 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

2227 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2228 delegate the secondary stack management when there is no suitable
2229 transient context, and the transient scope was intended to manage the

2234 the comment on usage.
2235 (Find_Transient_Context): Change the initinte loop into a while loop.

2467 during initialization. Remove the previous kludgy algorithm which

2529 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
2530 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
2531 (File_Type): Add Default_Initial_Condition aspect.
2533 2018-01-11 Pascal Obry <obry@adacore.com>
2535 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2537 2018-01-11 Bob Duff <duff@adacore.com>
2539 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2540 to match what the Libadalang-based version does.
2541 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2543 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2545 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2546 if it contains at least one component declaration employing a function
2547 call returning on the secondary stack.
2549 2018-01-11 Yannick Moy <moy@adacore.com>
2551 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2552 Update description of restriction SPARK_05 with SPARK 2014.

2555 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
2557 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
2559 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2561 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2562 sem_res.adb, sem_util.adb: Minor reformatting.
2564 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2566 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2567 has a delayed aspect which must be processed at the point the type is
2568 frozen. This mimics what is done when the predicate is provided by a
2571 2018-01-11 Doug Rupp <rupp@adacore.com>
2573 * init.c (vxworks): Add macro checks for __aarch64__.
2575 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2577 * exp_util.adb (Add_Failure_Expression): New routine.
2578 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2579 * sem_util.adb (Is_Current_Instance): Code cleanup.
2581 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2583 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2584 Default_Sec_Stack_Size.
2585 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2586 limit check so that the integer index does not overflow. Check the
2587 dynamic stack allocation does not cause the secondary stack pointer to
2589 (SS_Info): Align colons.
2590 (SS_Init): Cover the case when bootstraping with an old compiler that
2591 does not set Default_SS_Size.
2593 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2595 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2596 legality of an inherited operation that may require overriding, ignore
2597 primitive_wrappers that correspond to explicit operations that override
2598 an interface primitive.
2599 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2600 operation to which the class-wide expression applies is a protected op.
2601 with a primitive_wrapper, verify that the updated inherited expression
2602 does not contain an internal call to a protected function. This
2603 completes the implementation of AI12-0166.
2605 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2607 * ali.adb: Document the remaining letters available for ALI lines.
2608 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2609 * ali.ads: Update type With_Record. Field
2610 Implicit_With_From_Instantiation is no longer in use. Add field
2612 * csinfo.adb (CSinfo): Remove the setup for attribute
2613 Implicit_With_From_Instantiation.
2614 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2615 either implicitly or explicitly withed.
2616 (Is_Implicit_With_Clause): New routine.
2617 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2618 confusion with the with clause attribute by the same name.
2619 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2620 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2621 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2622 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2624 (Implicit_With_On_Parent): Mark the with clause as generated for a
2626 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2627 instantiation are no longer marked as Implicit_With_From_Instantiation
2628 because they are already marked as implicit.
2629 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2630 which marks implicit with clauses as related to an instantiation.
2631 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2632 (Parent_With): New routine.
2633 (Set_Implicit_With_From_Instantiation): Removed.
2634 (Set_Parent_With): New routine.
2635 * sinfo.ads: Update the documentation of attribute Implicit_With.
2636 Remove attribute Implicit_With_From_Instantiation along with
2637 occurrences in nodes. Add attribute Parent_With along with occurrences
2639 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2640 (Parent_With): New routine along with pragma Inline.
2641 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2642 (Set_Parent_With): New routine along with pragma Inline.
2644 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2646 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2647 entity when the enclosing construct is a body.
2649 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2651 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2652 Secondary_Stack_Size handling as a pragma is now generated for the
2653 corresponding aspect instead of an attribute. Pragma expression is
2654 relocated instead of evaluated. Discriminant of the corresponding
2655 record type is referenced rather than the type discriminant.
2656 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2657 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2658 * sem_ch13.adb (Analyze_One_Aspect): Transform
2659 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2660 because the attribute does not have visibility on a task type's
2661 discriminants when the type's definition is expanded.
2662 (Analyze_Attribute_Definition_Clause): Remove handling of
2663 Attribute_Secondary_Stack_Size.
2664 * snames.adb-tmpl, snames.ads-tmpl: Remove
2665 Attribute_Secondary_Stack_Size, no longer used.
2667 2018-01-11 Justin Squirek <squirek@adacore.com>
2669 * sem_ch8.adb: Minor comment fix.
2671 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2673 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2674 individual action because the action may denote a complex expression,
2675 such as a case statement, which in turn may contain additional
2678 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2680 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2681 analysis on a copy of the expression with a copy of the index variable,
2682 because full expansion will rewrite construct into a loop with the
2683 original loop variable.
2684 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2685 expression is an iterated component association. Full analysis takes
2686 place when construct is rewritten as a loop.
2687 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2688 is not safe for in-place assignment.
2689 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2690 entity with no homonym and no other entity in the scope.
2692 2018-01-11 Justin Squirek <squirek@adacore.com>
2694 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2695 message to be printed on the pragma argument identifier.
2697 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2699 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2700 entity of the generated invariant procedure in order to construct a
2701 proper entity chain.
2703 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2705 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2708 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2710 * einfo.ads, einfo.adb (Activation_Record_Component,
2711 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2712 Allow E_Discriminant.
2714 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2716 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2717 for atomic access once the component size is taken into account and
2718 also do it if the component type is Atomic or Volatile_Full_Access.
2720 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2722 * gnatvsn.ads: Bump copyright year.

2725 Alan Hayward <alan.hayward@arm.com>
2726 David Sherwood <david.sherwood@arm.com>

2739 Alan Hayward <alan.hayward@arm.com>
2740 David Sherwood <david.sherwood@arm.com>
2742 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2743 polynomial TYPE_VECTOR_SUBPARTS.
2745 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2746 Alan Hayward <alan.hayward@arm.com>
2747 David Sherwood <david.sherwood@arm.com>

2752 2018-01-03 Jakub Jelinek <jakub@redhat.com>
2754 Update copyright years.
2756 * gnat_ugn.texi: Bump @copying's copyright year.
