Hey, I've been working on the hashing asm, as I said before, by removing redundancies of functions and register moves, using logic to modify source and destinations to take advantage of processor hardware optimizations and doing some of the easy math myself so the processor doesn't have to.  Here's what I've done so far.  It's not much, but it works.  Don't go changing the github source just yet though.  For now, copy-paste this to replace your existing sha256_sse4_amd64.asm file.  For those of you without SSE4.1 (such as AMD users), copy paste this into you sse2_amd64 file instead and search-replace all uses of movntdqa with movdqa so the quick memory moves aren't used.


I'll be attacking the LAB_LOOP next.
