--- Comment #7 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
Is also not optimized on PowerPC:

f:
        .quad   .L.f,.TOC.@tocbase,0
.L.f:
        xor 4,3,4
        or 3,3,5
        xor 3,4,3
        extsw 3,3
        blr

and on aarch64:

f:
        eor     w1, w0, w1
        orr     w0, w0, w2
        eor     w0, w1, w0
        ret
