Evgenii Stratonikov	d891a9c591	Restructure code layout ... Provide default implementations in gf127 package and all optimizations in subpackages. This way it will be easier to use from a client.	2019-10-15 13:22:31 +03:00

Evgenii	6c75cc0871	Add pure Go hash implementation	2019-07-19 18:59:43 +03:00
Evgenii	c3cfe63e64	Add possibility to use different implementations in cli ... Also make API smaller and more consistent and fix typos in documentation.	2019-07-19 18:24:30 +03:00
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
