--- Comment #2 from Uroš Bizjak <ubizjak at gmail dot com> ---
On a related note, -march=i386 generates long sequences of rol insns, e.g.:

foo5:
        movl    4(%esp), %eax
        rolw    $8, %ax
        roll    $16, %eax
        rolw    $8, %ax
        movl    8(%esp), %edx
        rolw    $8, %dx
        roll    $16, %edx
        rolw    $8, %dx
        andl    %edx, %eax
        rolw    $8, %ax
        roll    $16, %eax
        rolw    $8, %ax
        ret

Please note that this arch doesn't have bswap insn, but this insn isn't
generated for optimized code anyway.
