Hmm, AFAICT the same seems to happen on powerpc64le:

        lbz 9,0(3)                      # Load zero
        ori 9,9,0x20                    # ors in 32
        rlwinm 9,9,0,0xff               # zero extend value AFAICT
        cmpwi 7,9,116


So far tested:

good: mipsel, x86_64, armhf (thumb2)
bad: aarch64, powerpc64le
