-# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
-# project. The module is, however, dual licensed under OpenSSL and
-# CRYPTOGAMS licenses depending on where you obtain it. For further
-# details see http://www.openssl.org/~appro/cryptogams/.

-# May 2011
-#
-# The module implements bn_GF2m_mul_2x2 polynomial multiplication used
-# in bn_gf2m.c. It's kind of low-hanging mechanical port from C for
-# the time being... Except that it has three code paths: pure integer
-# code suitable for any x86 CPU, MMX code suitable for PIII and later
-# and PCLMULQDQ suitable for Westmere and later. Improvement varies
-# from one benchmark and µ-arch to another. Below are interval values
-# for 163- and 571-bit ECDH benchmarks relative to compiler-generated
-# code:
-#
-# PIII 16%-30%
-# P4 12%-12%
-# Opteron 18%-40%
-# Core2 19%-44%
-# Atom 38%-64%
-# Westmere 53%-121%(PCLMULQDQ)/20%-32%(MMX)
-# Sandy Bridge 72%-127%(PCLMULQDQ)/27%-23%(MMX)
-#
-# Note that above improvement coefficients are not coefficients for
-# bn_GF2m_mul_2x2 itself. For example 120% ECDH improvement is result
-# of bn_GF2m_mul_2x2 being >4x faster. As it gets faster, benchmark
-# is more and more dominated by other subroutines, most notably by
-# BN_GF2m_mod[_mul]_arr...
