+# ====================================================================
+# 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...
