        sub-procedure Declared_In_Actual to handle properly the visibility
        of actuals in actual packages, that are themselves actuals to a
        actual package of the current instance. This mimics properly the
        visibility of formals of formal packages declared with a box,
        within the corresponding generic unit.

        defined in the current scope.

        * exp_util.adb (Insert_Actions): When inserting actions on a
        short circuit operator that has already been analyzed, do not park
        actions in node; instead introduce an N_Expression_With_Actions
        and insert actions immediately.
        Add guard for unexpected case of climbing up through statement

        * exp_ch3.adb (Expand_N_Object_Declaration): When a class-wide
        object is declared, it is rewritten as a renaming of an dynamic
        expression that wraps the initial value.  The renaming declaration
        is first given an internal name, to prevent collisions with the
        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.

2014-01-21  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_spark.adb, exp_spark.ads (Expand_SPARK_Call): Only replace
        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.
        * expander.adb (Expand): Call the light SPARK expansion in GNATprove
        mode.
        (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.

        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.
        (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.

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