-#
-# March, June 2010
-#
-# The module implements "4-bit" GCM GHASH function and underlying
-# single multiplication operation in GF(2^128). "4-bit" means that
-# it uses 256 bytes per-key table [+128 bytes shared table]. GHASH
-# function features so called "528B" variant utilizing additional
-# 256+16 bytes of per-key storage [+512 bytes shared table].
-# Performance results are for this streamed GHASH subroutine and are
-# expressed in cycles per processed byte, less is better:
-#
-#		gcc 3.4.x(*)	assembler
-#
-# P4		28.6		14.0		+100%
-# Opteron	19.3		7.7		+150%
-# Core2		17.8		8.1(**)		+120%
-# Atom		31.6		16.8		+88%
-# VIA Nano	21.8		10.1		+115%
-#
-# (*)	comparison is not completely fair, because C results are
-#	for vanilla "256B" implementation, while assembler results
-#	are for "528B";-)
-# (**)	it's mystery [to me] why Core2 result is not same as for
-#	Opteron;
-
-# May 2010
-#
-# Add PCLMULQDQ version performing at 2.02 cycles per processed byte.
-# See ghash-x86.pl for background information and details about coding
-# techniques.
-#
-# Special thanks to David Woodhouse for providing access to a
-# Westmere-based system on behalf of Intel Open Source Technology Centre.
-
-# December 2012
-#
-# Overhaul: aggregate Karatsuba post-processing, improve ILP in
-# reduction_alg9, increase reduction aggregate factor to 4x. As for
-# the latter. ghash-x86.pl discusses that it makes lesser sense to
-# increase aggregate factor. Then why increase here? Critical path
-# consists of 3 independent pclmulqdq instructions, Karatsuba post-
-# processing and reduction. "On top" of this we lay down aggregated
-# multiplication operations, triplets of independent pclmulqdq's. As
-# issue rate for pclmulqdq is limited, it makes lesser sense to
-# aggregate more multiplications than it takes to perform remaining
-# non-multiplication operations. 2x is near-optimal coefficient for
-# contemporary Intel CPUs (therefore modest improvement coefficient),
-# but not for Bulldozer. Latter is because logical SIMD operations
-# are twice as slow in comparison to Intel, so that critical path is
-# longer. A CPU with higher pclmulqdq issue rate would also benefit
-# from higher aggregate factor...
-#
-# Westmere	1.78(+13%)
-# Sandy Bridge	1.80(+8%)
-# Ivy Bridge	1.80(+7%)
-# Haswell	0.55(+93%) (if system doesn't support AVX)
-# Broadwell	0.45(+110%)(if system doesn't support AVX)
-# Skylake	0.44(+110%)(if system doesn't support AVX)
-# Bulldozer	1.49(+27%)
-# Silvermont	2.88(+13%)
-# Knights L	2.12(-)    (if system doesn't support AVX)
-# Goldmont	1.08(+24%)
-
-# March 2013
-#
-# ... 8x aggregate factor AVX code path is using reduction algorithm
-# suggested by Shay Gueron[1]. Even though contemporary AVX-capable
-# CPUs such as Sandy and Ivy Bridge can execute it, the code performs
-# sub-optimally in comparison to above mentioned version. But thanks
-# to Ilya Albrekht and Max Locktyukhin of Intel Corp. we knew that
-# it performs in 0.41 cycles per byte on Haswell processor, in
-# 0.29 on Broadwell, and in 0.36 on Skylake.
-#
-# Knights Landing achieves 1.09 cpb.
