+# This is AESNI-CBC+SHA256 stitch implementation. The idea, as spelled
+# in http://download.intel.com/design/intarch/papers/323686.pdf, is
+# that since AESNI-CBC encrypt exhibit *very* low instruction-level
+# parallelism, interleaving it with another algorithm would allow to
+# utilize processor resources better and achieve better performance.
+# SHA256 instruction sequences(*) are taken from sha512-x86_64.pl and
+# AESNI code is weaved into it. As SHA256 dominates execution time,
+# stitch performance does not depend on AES key length. Below are
+# performance numbers in cycles per processed byte, less is better,
+# for standalone AESNI-CBC encrypt, standalone SHA256, and stitched
+# subroutine:
+#
+# AES-128/-192/-256+SHA256 this(**)gain
+# Sandy Bridge 5.05/6.05/7.05+11.6 13.0 +28%/36%/43%
+# Ivy Bridge 5.05/6.05/7.05+10.3 11.6 +32%/41%/50%
+# Haswell 4.43/5.29/6.19+7.80 8.79 +39%/49%/59%
+# Bulldozer 5.77/6.89/8.00+13.7 13.7 +42%/50%/58%
+#
+# (*) there are XOP, AVX1 and AVX2 code pathes, meaning that
+# Westmere is omitted from loop, this is because gain was not
+# estimated high enough to justify the effort;
+# (**) these are EVP-free results, results obtained with 'speed
+# -evp aes-256-cbc-hmac-sha256' will vary by percent or two;

+# ====================================================================
+#
+# This module implements support for AES instructions as per PowerISA
+# specification version 2.07, first implemented by POWER8 processor.
+# The module is endian-agnostic in sense that it supports both big-
+# and little-endian cases. Data alignment in parallelizable modes is
+# handled with VSX loads and stores, which implies MSR.VSX flag being
+# set. It should also be noted that ISA specification doesn't prohibit
+# alignment exceptions for these instructions on page boundaries.
+# Initially alignment was handled in pure AltiVec/VMX way [when data
+# is aligned programmatically, which in turn guarantees exception-
+# free execution], but it turned to hamper performance when vcipher
+# instructions are interleaved. It's reckoned that eventual
+# misalignment penalties at page boundaries are in average lower
+# than additional overhead in pure AltiVec approach.

+# AES for SPARC T4.
+#
+# AES round instructions complete in 3 cycles and can be issued every
+# cycle. It means that round calculations should take 4*rounds cycles,
+# because any given round instruction depends on result of *both*
+# previous instructions:
+#
+# |0 |1 |2 |3 |4
+# |01|01|01|
+# |23|23|23|
+# |01|01|...
+# |23|...
+#
+# Provided that fxor [with IV] takes 3 cycles to complete, critical
+# path length for CBC encrypt would be 3+4*rounds, or in other words
+# it should process one byte in at least (3+4*rounds)/16 cycles. This
+# estimate doesn't account for "collateral" instructions, such as
+# fetching input from memory, xor-ing it with zero-round key and
+# storing the result. Yet, *measured* performance [for data aligned
+# at 64-bit boundary!] deviates from this equation by less than 0.5%:
+#
+# 128-bit key 192- 256-
+# CBC encrypt 2.70/2.90(*) 3.20/3.40 3.70/3.90
+# (*) numbers after slash are for
+# misaligned data.
+#
+# Out-of-order execution logic managed to fully overlap "collateral"
+# instructions with those on critical path. Amazing!
+#
+# As with Intel AES-NI, question is if it's possible to improve
+# performance of parallelizeable modes by interleaving round
+# instructions. Provided round instruction latency and throughput
+# optimal interleave factor is 2. But can we expect 2x performance
+# improvement? Well, as round instructions can be issued one per
+# cycle, they don't saturate the 2-way issue pipeline and therefore
+# there is room for "collateral" calculations... Yet, 2x speed-up
+# over CBC encrypt remains unattaintable:
+#
+# 128-bit key 192- 256-
+# CBC decrypt 1.64/2.11 1.89/2.37 2.23/2.61
+# CTR 1.64/2.08(*) 1.89/2.33 2.23/2.61
+# (*) numbers after slash are for
+# misaligned data.
+#
+# Estimates based on amount of instructions under assumption that
+# round instructions are not pairable with any other instruction
+# suggest that latter is the actual case and pipeline runs
+# underutilized. It should be noted that T4 out-of-order execution
+# logic is so capable that performance gain from 2x interleave is
+# not even impressive, ~7-13% over non-interleaved code, largest
+# for 256-bit keys.
+
+# To anchor to something else, software implementation processes
+# one byte in 29 cycles with 128-bit key on same processor. Intel
+# Sandy Bridge encrypts byte in 5.07 cycles in CBC mode and decrypts
+# in 0.93, naturally with AES-NI.

+# ====================================================================
+# 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/.
+# ====================================================================
+#
+# This module implements support for ARMv8 AES instructions. The
+# module is endian-agnostic in sense that it supports both big- and
+# little-endian cases. As does it support both 32- and 64-bit modes
+# of operation. Latter is achieved by limiting amount of utilized
+# registers to 16, which implies additional NEON load and integer
+# instructions. This has no effect on mighty Apple A7, where results
+# are literally equal to the theoretical estimates based on AES
+# instruction latencies and issue rates. On Cortex-A53, an in-order
+# execution core, this costs up to 10-15%, which is partially
+# compensated by implementing dedicated code path for 128-bit
+# CBC encrypt case. On Cortex-A57 parallelizable mode performance
+# seems to be limited by sheer amount of NEON instructions...
+#
+# Performance in cycles per byte processed with 128-bit key:
+#
+# CBC enc CBC dec CTR

+
+# Bit-sliced AES for ARM NEON
+#
+# February 2012.
+#
+# This implementation is direct adaptation of bsaes-x86_64 module for
+# ARM NEON. Except that this module is endian-neutral [in sense that
+# it can be compiled for either endianness] by courtesy of vld1.8's
+# neutrality. Initial version doesn't implement interface to OpenSSL,
+# only low-level primitives and unsupported entry points, just enough
+# to collect performance results, which for Cortex-A8 core are:
+#
+# encrypt 19.5 cycles per byte processed with 128-bit key
+# decrypt 22.1 cycles per byte processed with 128-bit key
+# key conv. 440 cycles per 128-bit key/0.18 of 8x block
+#
+# Snapdragon S4 encrypts byte in 17.6 cycles and decrypts in 19.7,
+# which is [much] worse than anticipated (for further details see
+# http://www.openssl.org/~appro/Snapdragon-S4.html).
+#
+# Cortex-A15 manages in 14.2/16.1 cycles [when integer-only code
+# manages in 20.0 cycles].
+#
+# When comparing to x86_64 results keep in mind that NEON unit is
+# [mostly] single-issue and thus can't [fully] benefit from
+# instruction-level parallelism. And when comparing to aes-armv4
+# results keep in mind key schedule conversion overhead (see
+# bsaes-x86_64.pl for further details)...
+#
+# <appro@openssl.org>

+# (*) This is ~10% worse than reported in paper. The reason is
