-# ====================================================================
-# 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 two code paths: code suitable
-# for any x86_64 CPU and PCLMULQDQ one suitable for Westmere and
-# later. Improvement varies from one benchmark and µ-arch to another.
-# Vanilla code path is at most 20% faster than compiler-generated code
-# [not very impressive], while PCLMULQDQ - whole 85%-160% better on
-# 163- and 571-bit ECDH benchmarks on Intel CPUs. Keep in mind that
-# these coefficients are not ones for bn_GF2m_mul_2x2 itself, as not
-# all CPU time is burnt in it...
