#
# Add AVX code path. See sha1-586.pl for further information.
# May 2013.
#
# Add AVX2+BMI code path. Initial attempt (utilizing BMI instructions
# and loading pair of consecutive blocks to 256-bit %ymm registers)
# did not provide impressive performance improvement till a crucial
# hint regarding the number of Xupdate iterations to pre-compute in
# advance was provided by Ilya Albrekht of Intel Corp.
