Evgenii Stratonikov 3de3046074 tz: optimize AVX2 implementation ... 1. Perform masking with 2 instructions instead of 3 (use arithmetic shift). 2. Broadcast data byte in one instruction at the start of byte-processing 3. Reorder instructions to reduce the amount of data hazards and resources contention. ``` name old time/op new time/op delta Sum/AVX2_digest-8 1.39ms ± 0% 1.22ms ± 0% -12.18% (p=0.000 n=9+7) name old speed new speed delta Sum/AVX2_digest-8 71.7MB/s ± 0% 81.7MB/s ± 0% +13.87% (p=0.000 n=9+7) ``` Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>		2022-03-22 12:25:13 +03:00
