--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Even with AVX we still have an extra move:
.L2:
        vpslldq $4, %xmm1, %xmm0
        vpaddd  %xmm1, %xmm0, %xmm0
        vpslldq $8, %xmm0, %xmm1
        vpaddd  %xmm1, %xmm0, %xmm0
        vmovdqa %xmm0, %xmm1
        subl    $1, %eax
        jne     .L2
