Error: Unrecognized opcode

[kim sook young]

hi,all

While compiling, Some weird messages occurred.
I  don't think rorw is available opcode on the ppc environment. do i?
I don't know why rorw opcodes are generated in assembly code.

----------------------------------------------------------------
Compiling smbd/oplock.c
/tmp/ccs9oFVa.s: Assembler messages:

the following is a part of the assembly code.

.L199:
        lis 9,global_oplock_port at ha
        la 9,global_oplock_port at l(9)
        lhz 0,10(1)
        rorw $8, 0
        sth 0,0(9)
        bl setup_kernel_oplock_pipe
        cmpwi 0,3,0
        bc 4,2,.L203
        li 3,0
        b .L205
----------------------------------------------------------------

I hope somebody would tip me off to the solution(?)

Thanks
regards
