# instruction and the 'lea' instruction itself, which is essential
|
||||
# for Intel Atom core.
|
||||
|
||||
# October 2010.
|
||||
#
|
||||
# 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
|
||||
# to free temporary registers.
|
||||
|
||||
# April 2011.
|
||||
#
|
||||
# Add AVX code path. See sha1-586.pl for further information.
