--- Comment #16 from Nicholas Piggin <npiggin at gmail dot com> ---
gcc-11 -O2 -mcpu=3Dpower10 now generates identical code that Bill listed for
trunk:

.L2:
        lwz 4,4(9)
        lwz 5,12(9)
        lwz 6,8(9)
        lwzu 8,16(9)
        add 10,4,10
        add 10,10,5
        add 7,6,7
        add 7,7,8
        bdnz .L2

Thanks all.=
