        * xsnamest.adb (XSnamesT): Remove special casing of Name_Error
        to give <Error>.  Not clear why this was there, but the compiler
        sources do not reference Name_Error, and this interfered with
        the circuits for pragma Unevaluated_Use_Of_Old.

2014-07-29  Hristian Kirtchev  <kirtchev@adacore.com>

        * sem_prag.adb (Process_Atomic_Shared_Volatile): Allow volatile

        * inline.ads, inline.adb: Package now contains subprograms that
        implement front-end inlining.  No functional changes, no test
        needed.

2014-07-29  Robert Dewar  <dewar@adacore.com>

        * exp_dbug.adb, g-expect.adb, sem_elab.adb: Minor typo fix.

        * sem_ch6.adb (Analyze_Return_Type): Reject a return type that
        is a limited view when the context is a package body, because
        there is no subsequent place at which the non-limited view may
        become visible.

        * sinfo.ads, par-ch3.adb: Minor reformatting.

2014-07-29  Jerome Lambourg  <lambourg@adacore.com>

        * expect.c (__gnat_expect_poll): New parameter dead_process
        used to return the dead process among the array of file
        descriptors. The Windows, VMS and HPUX implementations now
        properly report the dead process via this parameter. Other unixes
        don't need it.
        * g-expect.adb (Poll): Adapt to the C profile.
        (Expect_Internal): Use the new parameter to properly close the
        File Descriptor.  This then can be properly reported by the

        * sem_ch13.adb: Minor addition of ??? comment.
        (Rep_Item_Too_Late): Warn on case that is legal but could cause an
        expensive implicit conversion.
        * sem_ch3.adb (Build_Derived_Type): Set Derived_Type_Link if needed.

2014-07-29  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch3.adb (Build_Init_Procedure): Renamed Local_DF_Id
        to DF_Id. Add new local variable DF_Call. Do not perform any
        elaboration-related checks on the call to the partial finalization
        routine within an init proc to avoid generating bogus elaboration
        warnings on expansion-related code.
        * sem_elab.adb (Check_A_Call): Move constant Access_Case to
        the top level of the routine.  Ensure that Output_Calls takes
        into account flags -gnatel and -gnatwl when emitting warnings
        or info messages.
        (Check_Internal_Call_Continue): Update the call to Output_Calls.
        (Elab_Warning): Moved to the top level of routine Check_A_Call.
        (Emit): New routines.
        (Output_Calls): Add new formal parameter Check_Elab_Flag along with a
        comment on usage. Output all warnings or info messages only when the
        caller context demands it and the proper elaboration flag is set.

        * sem_ch6.adb (Check_Return_Subtype_Indication): Reject a return
        subtype indication in an extended return statement when the
        return value is an ancestor of the return type of the function,
        and that return type is a null record extension.

2014-07-29  Thomas Quinot  <quinot@adacore.com>

        * sem_ch13.adb (Rep_Item_Too_Late): Specialize/clarify error
        message produced for the case of a type-related representation

        in an access type definition can carry a null_exclusion indicator.
        * sem_ch3.adb (Access_Type_Declaration): If the subtype indication
        carries a null_exclusion indicator, verify that the subtype
        indication denotes an access type, and create a null-excluding
        subtype for it.
        * sinfo.ads, sinfo.adb: New attribute Null_Excluding_Subtype,
        defined on N_Access_To_Object_Definition to indicate that the
        subtype indication carries a null_exclusion indicator.

        * exp_ch6.adb (Add_Extra_Actual): Do not construct
        the extra actual by name, generate a reference instead.

2014-07-29  Arnaud Charlet  <charlet@adacore.com>

        * sem_ch4.adb (Complete_Object_Operation): If the type of the
        candidate subprogram is a limited view, use non-limited view

        * types.ads: Minor correction to range given for Mechanism_Type.
        * exp_ch6.adb (Add_Invariant_And_Predicate_Checks): Do not
        check predicate on way out for OUT or IN OUT parameters.
        * par-ch3.adb (P_Constraint_Opt): Handle missing RANGE keyword

        * g-debpoo.adb
        (Default_Alignment): Rename as Storage_Alignment. This is not
        a "default" that can be overriden. Augment comment to clarify
        intent and document why we need to manage alignment padding.
        (Header_Offset): Set to Header'Object_Size instead of 'Size
        rounded up to Storage_Alignment. Storage_Alignment on the
        allocation header is not required by our internals so was
        overkill. 'Object_Size is enough to ensure proper alignment
        of the header address when substracted from a storage address
        aligned on Storage_Alignment.
        (Minimum_Allocation): Rename as Extra_Allocation, conveying that
        this is always added on top of the incoming allocation requests.
        (Align): New function, to perform alignment rounding operations.
        (Allocate): Add comments on the Storage_Address computation
        scheme and adjust so that the alignment padding applies to that
        (Storage_Address) only.

        loop declarations as well.
        * exp_ch5.adb (Expand_Loop_Statement): Apply Qualify_Entity_Names
        to an iterator loop, because it may contain local renaming

        indexed_components that are instances of Ada 2012 container
        indexing operations. Analysis and resolution of such nodes

        Generalized_Indexing attribute when appropriate.

        Generalized_Indexing.

        * sem_prag.adb (Analyze_Pragma/Pragma_SPARK_Mode):
        Issue an error when the pragma is applied to a generic unit,
        a generic declaration, or inside a generic.

        * s-taskin.ads: Minor comment fix.
        * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
        just direct dependents. If this is actually an abort, each task
        will take care of aborting its dependents, so all dependents will
        get aborted, as before. However, when this is called the second
        time from Vulnerable_Complete_Master "for convenience" (i.e. to
        kill off tasks waiting at terminate alternatives), aborting
        indirect dependents is wrong, because it causes some unrelated
        tasks to get aborted.

        the original one. the modification of the name must preserve
        the source location of the original, to prevent spurious errors

        of the  construct whose value is indeterminate because of a
        call to a function with in-out parameter in another component,
        when there is no mandated order of execution between the two

        (Expander_Mode_Restore, Expander_Mode_Save_And_Set): Ignore
        save/restore actions for Expander_Active flag in GNATprove mode,
        similar to what is done in ASIS mode.
        * frontend.adb (Frontend): Generic bodies are instantiated in
        GNATprove mode.
        * gnat1drv.adb (Adjust_Global_Switches): Set operating
        mode to Check_Semantics in GNATprove mode, although a light
        expansion is still performed.
        (Gnat1drv): Set Back_End_Mode to
        Declarations_Only in GNATprove mode, and later on special case
        the GNATprove mode to continue analysis anyway.
        * lib-writ.adb (Write_ALI): Always generate ALI files in
        GNATprove mode.
        * opt.adb, opt.ads (Full_Expander_Active): Make it equivalent to
        Expander_Active.
        (SPARK_Mode): Renamed as GNATprove_Mode.
        * sem_aggr.adb (Aggregate_Constraint_Checks): Add checks in the
        tree in GNATprove_Mode.
        * sem_ch12.adb (Analyze_Package_Instantiation): Always instantiate
        body in GNATprove mode.
        (Need_Subprogram_Instance_Body): Always instantiate body in GNATprove
        mode.
        * sem_ch3.adb (Constrain_Index, Process_Range_Expr_In_Decl):
        Make sure side effects are removed in GNATprove mode.

        * gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Robustify tests
        for aliased objects with an unconstrained nominal subtype.
        * gcc-interface/trans.c (Call_to_gnu): Likewise.
        (gnat_to_gnu) <case N_Op_Not>: Robustify test for private type.
        <case N_Op_Minus>: Remove useless code.
        (Exception_Handler_to_gnu_zcx): Minor tweaks.

        * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Record_Subtype>:
        Tidy up.  For a subtype with discriminants and variant part, if a
        variant is statically selected and the fields all have a constant
        position, put them in order of increasing position.  Likewise if
        no variant part but representation clause is present.
        * gcc-interface/utils.c (make_packable_type): Robustify.
        (maybe_pad_type): Use local variable and tidy up condition.  If no
        alignment is specified, use the original one.
        (create_type_stub_decl): Minor tweak.
        (convert) <case VECTOR_CST>: Fix typo.
        <case CONSTRUCTOR>: Deal with padding types around the same type.
        Do not punt on missing fields.
        (unchecked_convert): Call finish_record_type to lay out the special
        record types made for conversions from/to problematic integer types.
        Bump the alignment of CONSTRUCTORs before converting them to a more
        aligned type.

        * gcc-interface/decl.c (gnat_to_gnu_entity) <case E_Component>: Remove
        obsolete code for type_annotate_only mode, simplify code and slightly
        improve wording of comments.
