307 comment about the memset case.
309 2018-05-30 Bob Duff <duff@adacore.com>
311 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
312 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
313 We need to analyze it as part of analyzing the block, so that if the
314 call to Element that initializes Elmt_Decl returns on the secondary
315 stack, the block will ss_mark/ss_release. This block is inside the
316 loop; we don't want to leak memory until the loop exits. The purpose
317 of analyzing Elmt_Decl first was to catch the error of modifying it,
318 which is illegal because it's a loop parameter. The above causes us to
319 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
320 it on the Element entity, so we end up with an E_Variable node with the
322 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
323 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
324 parameter not allowed" error if Is_Loop_Parameter.
325 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
326 trigger the call to Diagnose_Non_Variable_Lhs.

340 2018-05-30 Ed Schonberg <schonberg@adacore.com>
342 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
343 a package body that is a compilation unit may contain blocks that
344 declare local subprograms. In Subprogram_Unnesting Mode such
345 subprograms must be handled as nested inside the (implicit) elaboration
346 procedure that executes that statement part. To handle properly uplevel
347 references we construct that subprogram explicitly, to contain blocks
348 and inner subprograms, The statement part of the compilation unit
349 becomes a call to this subprogram. This is only done if blocks are
350 present in the statement list of the body.
352 2018-05-30 Bob Duff <duff@adacore.com>

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

661 of actual have uplevel references.
663 2018-05-28 Ed Schonberg <schonberg@adacore.com>

686 value when converting a float value to a fixed-point value. This is
687 required for CCG because it handles fixed-point types by means of
688 unsigned integer type variables. The range check is now performed using
689 the integer value stored in this temporary.
691 2018-05-28 Yannick Moy <moy@adacore.com>

725 2018-05-28 Ed Schonberg <schonberg@adacore.com>
727 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
728 when bounds of fixed type are static, to remove some spuerfluous
729 implicit conversions and provide an accurate result when converting
730 back and forth between the fixed point type and a floating point type.
732 2018-05-28 Ed Schonberg <schonberg@adacore.com>

737 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
739 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
740 replaced, if any; all callers changed.
741 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
742 constant with private view so we take the address of that entity.
743 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
744 any; all callers changed. Handle N_Indexed_Component like
745 N_Attribute_Reference. Add N_Type_Conversion case.
746 (Visit_Node): Indexed references can be uplevel if the type isn't
748 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
749 been relocated, set first_named pointer in original node as well.
751 2018-05-28 Ed Schonberg <schonberg@adacore.com>
753 * exp_aggr.adb (Flatten): Copy tree of expression in a component
754 association with a range or a set of discrete choices, rather than
755 relocating the node. This avoids inconsistencies in the tree when
756 handling nested subprograms with uplevel references for LLVM.

822 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
823 includes a call to function to which it applies. This may mean an
824 omission of an attribute reference 'Result, in particular if the
825 function is pqrameterless.

841 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
842 end with the linker section, if any.
843 (List_Entities): Do not output the linker section for record types,
844 array types and variables.
845 (Print_Expr): Factor out common processing for unary operators and
846 special values. Adjust and reorder the various cases.

860 Expand range of type to match the address space of the target.

863 2018-05-25 Ed Schonberg <schonberg@adacore.com>
865 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
866 of a fixed point type and the parent is a multiplying operation,
867 resolve the operand with its own type because the context will impose a
868 resulting type on the result of the multiplication by means of
869 approriate conversion.
871 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
873 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
874 the in-place initialization aggregate created for pragmas
875 Initialize_Scalars or Normalize_Scalars is performed with checks
878 2018-05-25 Arnaud Charlet <charlet@adacore.com>
880 * exp_aggr.adb (Convert_To_Positional): Bump default for
881 Max_Others_Replicate to 32. Update comments.
882 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
883 (No_File_Info_Cache): Initialize separately.

904 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
905 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
906 into three distring cases rather than in one loop which attempts to
907 handle all three cases. This rewrite eliminates an issue where the last
908 frame of the stack cannot be freed, thus causing the memory range of a
909 new frame to approach the overflow point of the memory index type.
910 Since the overflow is logically treated as a
911 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
912 (SS_Allocate_Static): New routine. The routine factorizes the static
913 secondary stack-related code from the former SS_Allocate.
915 2018-05-25 Sergey Rybin <rybin@adacore.com>

922 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
923 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
924 is created when the proper body of the stub is analyzed.
925 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
926 is the proper body of a subunit, the cloned body must be inserted in
927 the declarative list that contains the stub.
929 2018-05-25 Justin Squirek <squirek@adacore.com>
931 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
932 generate code for 6.5(8-10) so that we don't get an assertion error
933 when dealing with an incomplete return type.
935 2018-05-25 Arnaud Charlet <charlet@adacore.com>

938 carrying very large strings.

964 2018-05-25 Ed Schonberg <schonberg@adacore.com>
966 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
967 Validate_Derived_Type_Instance, to verify that all interfaces
968 implemented by the formal type are also implemented by the actual. The
969 verification is complicated when an interface of the formal is declared
970 in a generic unit and the actual is declared in an instance of it.
971 There is currently no mechanism to relate an interface declared within
972 a generic to the corresponding interface in an instance, so we must
973 traverse the list of interfaces of the actual, looking for a name
974 match, and verifying that that interface is declared in an instance.
976 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
978 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
979 assertions; replace function versions of Next_Formal/Next_Actual with

2210 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2211 delegate the secondary stack management when there is no suitable
2212 transient context, and the transient scope was intended to manage the

2217 the comment on usage.
2218 (Find_Transient_Context): Change the initinte loop into a while loop.

2224 routine Find_Transient_Context.

2450 during initialization. Remove the previous kludgy algorithm which
2451 attempts to manage the secondary stack at the object creation site.

2532 2018-01-11 Yannick Moy <moy@adacore.com>
2534 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2535 Update description of restriction SPARK_05 with SPARK 2014.
2536 * gnat_rm.texi: Regenerate.
2538 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
2540 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
2542 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2544 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2545 sem_res.adb, sem_util.adb: Minor reformatting.
2547 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2549 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2550 has a delayed aspect which must be processed at the point the type is
2551 frozen. This mimics what is done when the predicate is provided by a
2554 2018-01-11 Doug Rupp <rupp@adacore.com>
2556 * init.c (vxworks): Add macro checks for __aarch64__.
2558 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2560 * exp_util.adb (Add_Failure_Expression): New routine.
2561 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2562 * sem_util.adb (Is_Current_Instance): Code cleanup.
2564 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2566 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2567 Default_Sec_Stack_Size.
2568 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2569 limit check so that the integer index does not overflow. Check the
2570 dynamic stack allocation does not cause the secondary stack pointer to
2572 (SS_Info): Align colons.
2573 (SS_Init): Cover the case when bootstraping with an old compiler that
2574 does not set Default_SS_Size.
2576 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2578 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2579 legality of an inherited operation that may require overriding, ignore
2580 primitive_wrappers that correspond to explicit operations that override
2581 an interface primitive.
2582 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2583 operation to which the class-wide expression applies is a protected op.
2584 with a primitive_wrapper, verify that the updated inherited expression
2585 does not contain an internal call to a protected function. This
2586 completes the implementation of AI12-0166.
2588 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2590 * ali.adb: Document the remaining letters available for ALI lines.
2591 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2592 * ali.ads: Update type With_Record. Field
2593 Implicit_With_From_Instantiation is no longer in use. Add field
2595 * csinfo.adb (CSinfo): Remove the setup for attribute
2596 Implicit_With_From_Instantiation.
2597 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2598 either implicitly or explicitly withed.
2599 (Is_Implicit_With_Clause): New routine.
2600 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2601 confusion with the with clause attribute by the same name.
2602 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2603 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2604 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2605 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2607 (Implicit_With_On_Parent): Mark the with clause as generated for a
2609 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2610 instantiation are no longer marked as Implicit_With_From_Instantiation
2611 because they are already marked as implicit.
2612 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2613 which marks implicit with clauses as related to an instantiation.
2614 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2615 (Parent_With): New routine.
2616 (Set_Implicit_With_From_Instantiation): Removed.
2617 (Set_Parent_With): New routine.
2618 * sinfo.ads: Update the documentation of attribute Implicit_With.
2619 Remove attribute Implicit_With_From_Instantiation along with
2620 occurrences in nodes. Add attribute Parent_With along with occurrences
2622 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2623 (Parent_With): New routine along with pragma Inline.
2624 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2625 (Set_Parent_With): New routine along with pragma Inline.
2627 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2629 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2630 entity when the enclosing construct is a body.
2632 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2634 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2635 Secondary_Stack_Size handling as a pragma is now generated for the
2636 corresponding aspect instead of an attribute. Pragma expression is
2637 relocated instead of evaluated. Discriminant of the corresponding
2638 record type is referenced rather than the type discriminant.
2639 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2640 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2641 * sem_ch13.adb (Analyze_One_Aspect): Transform
2642 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2643 because the attribute does not have visibility on a task type's
2644 discriminants when the type's definition is expanded.
2645 (Analyze_Attribute_Definition_Clause): Remove handling of
2646 Attribute_Secondary_Stack_Size.
2647 * snames.adb-tmpl, snames.ads-tmpl: Remove
2648 Attribute_Secondary_Stack_Size, no longer used.
2650 2018-01-11 Justin Squirek <squirek@adacore.com>
2652 * sem_ch8.adb: Minor comment fix.
2654 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2656 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2657 individual action because the action may denote a complex expression,
2658 such as a case statement, which in turn may contain additional
2661 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2663 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2664 analysis on a copy of the expression with a copy of the index variable,
2665 because full expansion will rewrite construct into a loop with the
2666 original loop variable.
2667 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2668 expression is an iterated component association. Full analysis takes
2669 place when construct is rewritten as a loop.
2670 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2671 is not safe for in-place assignment.
2672 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2673 entity with no homonym and no other entity in the scope.
2675 2018-01-11 Justin Squirek <squirek@adacore.com>
2677 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2678 message to be printed on the pragma argument identifier.
2680 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2682 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2683 entity of the generated invariant procedure in order to construct a
2684 proper entity chain.
2686 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2688 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2691 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2693 * einfo.ads, einfo.adb (Activation_Record_Component,
2694 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2695 Allow E_Discriminant.
2697 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2699 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2700 for atomic access once the component size is taken into account and
2701 also do it if the component type is Atomic or Volatile_Full_Access.
2703 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2705 * gnatvsn.ads: Bump copyright year.
2707 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2708 Alan Hayward <alan.hayward@arm.com>
2709 David Sherwood <david.sherwood@arm.com>

2715 Alan Hayward <alan.hayward@arm.com>
2716 David Sherwood <david.sherwood@arm.com>

2722 Alan Hayward <alan.hayward@arm.com>
2723 David Sherwood <david.sherwood@arm.com>
2725 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2726 polynomial TYPE_VECTOR_SUBPARTS.
2728 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2729 Alan Hayward <alan.hayward@arm.com>
2730 David Sherwood <david.sherwood@arm.com>
2732 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
2735 2018-01-03 Jakub Jelinek <jakub@redhat.com>
2737 Update copyright years.
2739 * gnat_ugn.texi: Bump @copying's copyright year.
