--- Comment #5 from vekumar at gcc dot gnu.org ---
On bdver4 when we enable -march=bdver4 and -mno-prefer-avx128 vectorizes using
YMM
Otherwise uses vprotq instruction.

.L13:
        vmovdqa (%r8,%r9), %ymm0
        incq    %rax
        vpsrlq  $32, %ymm0, %ymm1
        vpsllq  $32, %ymm0, %ymm0
        vpor    %ymm0, %ymm1, %ymm0
        vmovdqa %ymm0, (%rdx,%r9)
        addq    $32, %r9
        cmpq    %rax, %r10
        ja      .L13
