--- 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
