11 # AES-NI-CTR+GHASH stitch.

13 # February 2013
14 #
15 # OpenSSL GCM implementation is organized in such way that its
16 # performance is rather close to the sum of its streamed components,
17 # in the context parallelized AES-NI CTR and modulo-scheduled
18 # PCLMULQDQ-enabled GHASH. Unfortunately, as no stitch implementation
19 # was observed to perform significantly better than the sum of the
20 # components on contemporary CPUs, the effort was deemed impossible to
21 # justify. This module is based on combination of Intel submissions,
22 # [1] and [2], with MOVBE twist suggested by Ilya Albrekht and Max
23 # Locktyukhin of Intel Corp. who verified that it reduces shuffles
24 # pressure with notable relative improvement, achieving 1.0 cycle per
25 # byte processed with 128-bit key on Haswell processor, and 0.74 -
26 # on Broadwell. [Mentioned results are raw profiled measurements for
27 # favourable packet size, one divisible by 96. Applications using the
28 # EVP interface will observe a few percent worse performance.]
