        * combine.c (try_combine): Explicitly check whether GET_CODE is
        a SET or a CLOBBER, instead on checking that it isn't a USE.

        2006-11-22  Peter Bergner  <bergner@vnet.ibm.com>
        * config/rs6000/rs6000.c (get_store_dest): New.
        (adjacent_mem_locations): Use get_store_dest() to get
        the rtl of the store destination.
