Evgenii	c68e38b943	Inline asm function in loop for AVX2 implementation Right now AVX2 implementation looses to C binding in speed. This is probably, because of 2 things: 1. Go does not inline `mulBitRightx2` in loop iteration. 2. `minmax` is loaded every time from memory. In this PR: 1. Unroll `mulBitRightx2` manually and use `mulByteRightx2` instead. 2. Generate `minmax` in place without `LOAD/LEA` instructions.	2019-07-19 16:11:06 +03:00

Inline asm function in loop for AVX2 implementation

Right now AVX2 implementation looses to C binding in speed.
This is probably, because of 2 things:
1. Go does not inline `mulBitRightx2` in loop iteration.
2. `minmax` is loaded every time from memory.

In this PR:
1. Unroll `mulBitRightx2` manually and use `mulByteRightx2` instead.
2. Generate `minmax` in place without `LOAD/LEA` instructions.
