    gcc/
    * tree-ssa-math-opts.c (find_bswap_or_nop): Zero out bytes in cmpxchg
    and cmpnop in two steps: first the ones not accessed in original gimple
    expression in a endian independent way and then the ones not accessed
    in the final result in an endian-specific way.
    (bswap_replace): Stop doing big endian adjustment.
