Optimize vpermtiw/b to vpunpcklqdq for certain cases.
Assembly Optimization like:
- vmovq %xmm0, %xmm2
- vmovdqa .LC0(%rip), %xmm0
vmovq %xmm1, %xmm1
- vpermi2w %xmm1, %xmm2, %xmm0
+ vmovq %xmm0, %xmm0
+ vpunpcklqdq %xmm1, %xmm0, %xmm0
...
-.LC0:
- .value 0
- .value 1
- .value 2
- .value 3
- .value 8
- .value 9
- .value 10
- .value 11
