Subject: [PATCH] 2003-09-03  Dave Brolley  <brolley@redhat.com>

        * frv.opc (parse_A, parse_A0, parse_A1): New parse handlers.
        * frv.cpu (UNIT): Add IALL, FMALL, FMLOW, STORE, SCAN, DCPL, MDUALACC,
        MCLRACC-1.
        (A): Removed operand.
        (A0,A1): New operands replace operand A.
        (mnop): Now a real insn
        (mclracc): Removed insn.
        (mclracc-0, mclracc-1): New insns replace mclracc.
        (all insns): Use new UNIT attributes.
