14 # Add SSSE3 code path, 20-25% improvement [over original SSE2 code].

33 # (*) whichever best applicable.
34 # (**) x86_64 assembler performance is presented for reference
35 # purposes, the results are for integer-only code.
36 # (***) paddq is increadibly slow on Atom.
37 #
38 # IALU code-path is optimized for elder Pentiums. On vanilla Pentium
39 # performance improvement over compiler generated code reaches ~60%,
40 # while on PIII - ~35%. On newer ยต-archs improvement varies from 15%
41 # to 50%, but it's less important as they are expected to execute SSE2
42 # code-path, which is commonly ~2-3x faster [than compiler generated
43 # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even
44 # though it does not use 128-bit operations. The latter means that
45 # SSE2-aware kernel is no longer required to execute the code. Another
46 # difference is that new code optimizes amount of writes, but at the
47 # cost of increased data cache "footprint" by 1/2KB.
