--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
it looks better overall but the key difference is:

-       movzwl  8(%ebp), %edi
+       movzwl  8(%ebp), %eax
+       movw    %ax, 30(%esp)
...
-       vmovd   %edi, %xmm1
+       vpbroadcastw    30(%esp), %xmm2
+       vpbroadcastw    30(%esp), %ymm0
...
-       vmovd   %edi, %xmm0
...
-       vpbroadcastw    %xmm1, %xmm1
-       vpbroadcastw    %xmm0, %ymm0

I wonder whether optimal would be

        vpbroadcasstw 8(%ebp), %xmm2
        vpbroadcasstw 8(%ebp), %ymm0

though.=
