Resulting asm is quite different w/ current mainline:



_Z4testU8__vectorxS_S_:

vmovdqa%xmm2, -24(%rsp)

vpsrlq$32, %xmm0, %xmm3

vpmuldq%xmm1, %xmm0, %xmm2

vpmuldq%xmm1, %xmm3, %xmm1

vpand.LC0(%rip), %xmm1, %xmm1

vpsrlq$32, %xmm2, %xmm2

vmovd-24(%rsp), %xmm4

vpor%xmm1, %xmm2, %xmm1

vpaddd%xmm0, %xmm1, %xmm1

vpsrad$31, %xmm0, %xmm0

vpsrad%xmm4, %xmm1, %xmm1

vpsubd%xmm0, %xmm1, %xmm0

ret
