        * exp_util.adb (Build_Allocate_Deallocate_Proc): Rewrite
        the logic that generates a runtime check to determine the
        controlled status of the object about to be allocated or
        deallocated. Class-wide types now always use a runtime check
        even if they appear as generic actuals.
        (Find_Object): Detect
        a special case that involves interface class-wide types because
        the object appears as a complex expression.

        a generic declaration, or inside a generic.

2014-01-31  Yannick Moy  <moy@adacore.com>

        * 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.

        entity already declared, and then the name is modified to reflect
        the original one. the modification of the name must preserve
        the source location of the original, to prevent spurious errors
        when compiling with style checks if the declaration involves
        more than one entity.

        subprograms by alias for renamings, not for inherited primitive
        operations.
        * exp_util.adb (Expand_Subtype_From_Expr): Apply the expansion
        in GNATprove mode.
        (Remove_Side_Effects): Apply the removal in
        GNATprove mode, for the full analysis of expressions.

        GNATprove mode.
        * gnat1drv.adb (Adjust_Global_Switches): Set operating

        * 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.

        * 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.

        obsolete code for type_annotate_only mode, simplify code and slightly
        improve wording of comments.
