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

+# AES-NI-CTR+GHASH stitch.
+#
+# February 2013
+#
+# OpenSSL GCM implementation is organized in such way that its
+# performance is rather close to the sum of its streamed components,
+# in the context parallelized AES-NI CTR and modulo-scheduled
+# PCLMULQDQ-enabled GHASH. Unfortunately, as no stitch implementation
+# was observed to perform significantly better than the sum of the
+# components on contemporary CPUs, the effort was deemed impossible to
+# justify. This module is based on combination of Intel submissions,
+# [1] and [2], with MOVBE twist suggested by Ilya Albrekht and Max
+# Locktyukhin of Intel Corp. who verified that it reduces shuffles
+# pressure with notable relative improvement, achieving 1.0 cycle per
+# byte processed with 128-bit key on Haswell processor, and 0.74 -
+# on Broadwell. [Mentioned results are raw profiled measurements for
+# favourable packet size, one divisible by 96. Applications using the
+# EVP interface will observe a few percent worse performance.]
