# higher coefficients are observed on VIA Nano and Bulldozer has more
# to do with specifics of their architecture [which is topic for
# separate discussion].
#
# November 2012.
#
# Add AVX2 code path. Two consecutive input blocks are loaded to
# 256-bit %ymm registers, with data from first block to least
# significant 128-bit halves and data from second to most significant.
# The data is then processed with same SIMD instruction sequence as
# for AVX, but with %ymm as operands. Side effect is increased stack
# frame, 448 additional bytes in SHA256 and 1152 in SHA512.
