        * gcc-interface/ada-tree.h (TYPE_REPRESENTATIVE_ARRAY): New language
        specific node.  Representative array type for VECTOR_TYPE entities.
        * gcc-interface/utils.c (handle_vector_type_attribute): New handler.
        Turn an ARRAY_TYPE entity into a VECTOR_TYPE.
        (gnat_types_compatible_p): Handle VECTOR_TYPEs.
        (convert): Likewise.  Arrange to produce VECTOR_CST out of constant
        array aggregates for VECTOR_TYPE entities.
        (unchecked_convert): Likewise.
        (maybe_vector_array): New function. If EXP has VECTOR_TYPE, return EXP
        converted to the associated TYPE_REPRESENTATIVE_ARRAY.
        (handle_pure_attribute, handle_sentinel_attribute,
        handle_noreturn_attribute, handle_malloc_attribute,
        handle_vector_size_attribute): Replace uses of qE format by qs.
        Remove GCC_DIAG_STYLE definition.
        * gcc-interface/trans.c (gnat_to_gnu) <N_Indexed_Component>: Convert
        vector input to representative array type on entry.
        <N_Op_Eq, etc>: Likewise.
        * gcc-interface/gigi.h (maybe_vector_array): Declare.
        (VECTOR_TYPE_P): New predicate.
        * gcc-interface/misc.c (gnat_print_type): Handle VECTOR_TYPE.

        testsuite/
