-# The code was revised to minimize code size and to maximize

-# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
-# is to offload message schedule denoted by Wt in NIST specification,
-# or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module
-# for background and implementation details. The only difference from
-# 32-bit code is that 64-bit code doesn't have to spill @X[] elements
