+## Constant-time SSSE3 AES core implementation.

+######################################################################
+# Adapted from the original x86_64 version and <appro@openssl.org>'s ARMv8
+# version.
+#
+# armv7, aarch64, and x86_64 differ in several ways:
+#
+# * x86_64 SSSE3 instructions are two-address (destination operand is also a
+#   source), while NEON is three-address (destination operand is separate from
+#   two sources).
+#
+# * aarch64 has 32 SIMD registers available, while x86_64 and armv7 have 16.
+#
+# * x86_64 instructions can take memory references, while ARM is a load/store
+#   architecture. This means we sometimes need a spare register.
+#
+# * aarch64 and x86_64 have 128-bit byte shuffle instructions (tbl and pshufb),
+#   while armv7 only has a 64-bit byte shuffle (vtbl).
+#
+# This means this armv7 version must be a mix of both aarch64 and x86_64
+# implementations. armv7 and aarch64 have analogous SIMD instructions, so we
+# base the instructions on aarch64. However, we cannot use aarch64's register
+# allocation. x86_64's register count matches, but x86_64 is two-address.
+# vpaes-armv8.pl already accounts for this in the comments, which use
+# three-address AVX instructions instead of the original SSSE3 ones. We base
+# register usage on these comments, which are preserved in this file.
+#
+# This means we do not use separate input and output registers as in aarch64 and
+# cannot pin as many constants in the preheat functions. However, the load/store
+# architecture means we must still deviate from x86_64 in places.
+#
+# Next, we account for the byte shuffle instructions. vtbl takes 64-bit source
+# and destination and 128-bit table. Fortunately, armv7 also allows addressing
+# upper and lower halves of each 128-bit register. The lower half of q{N} is
+# d{2*N}. The upper half is d{2*N+1}. Instead of the following non-existent
+# instruction,
+#
+#     vtbl.8 q0, q1, q2   @ Index each of q2's 16 bytes into q1. Store in q0.
+#
+# we write:
+#
+#     vtbl.8 d0, q1, d4   @ Index each of d4's 8 bytes into q1. Store in d0.
+#     vtbl.8 d1, q1, d5   @ Index each of d5's 8 bytes into q1. Store in d1.
+#
+# For readability, we write d0 and d1 as q0#lo and q0#hi, respectively and
+# post-process before outputting. (This is adapted from ghash-armv4.pl.) Note,
+# however, that destination (q0) and table (q1) registers may no longer match.
+# We adjust the register usage from x86_64 to avoid this. (Unfortunately, the
+# two-address pshufb always matched these operands, so this is common.)
+#
+# This file also runs against the limit of ARMv7's ADR pseudo-instruction. ADR
+# expands to an ADD or SUB of the pc register to find an address. That immediate
+# must fit in ARM's encoding scheme: 8 bits of constant and 4 bits of rotation.
+# This means larger values must be more aligned.
+#
+# ARM additionally has two encodings, ARM and Thumb mode. Our assembly files may
+# use either encoding (do we actually need to support this?). In ARM mode, the
+# distances get large enough to require 16-byte alignment. Moving constants
+# closer to their use resolves most of this, but common constants in
+# _vpaes_consts are used by the whole file. Affected ADR instructions must be
+# placed at 8 mod 16 (the pc register is 8 ahead). Instructions with this
+# constraint have been commented.
+#
+# For details on ARM's immediate value encoding scheme, see
+# https://alisdair.mcdiarmid.org/arm-immediate-value-encoding/
+#
+# Finally, a summary of armv7 and aarch64 SIMD syntax differences:
+#
+# * armv7 prefixes SIMD instructions with 'v', while aarch64 does not.
+#
+# * armv7 SIMD registers are named like q0 (and d0 for the half-width ones).
+#   aarch64 names registers like v0, and denotes half-width operations in an
+#   instruction suffix (see below).
+#
+# * aarch64 embeds size and lane information in register suffixes. v0.16b is
+#   16 bytes, v0.8h is eight u16s, v0.4s is four u32s, and v0.2d is two u64s.
+#   armv7 embeds the total size in the register name (see above) and the size of
+#   each element in an instruction suffix, which may look like vmov.i8,
+#   vshr.u8, or vtbl.8, depending on instruction.

+
+# This file was adapted to AArch64 from the 32-bit version in ghash-armv4.pl. It
+# implements the multiplication algorithm described in:
+#
+# Câmara, D.; Gouvêa, C. P. L.; López, J. & Dahab, R.: Fast Software
+# Polynomial Multiplication on ARM Processors using the NEON Engine.
+#
+# http://conradoplg.cryptoland.net/files/2010/12/mocrysen13.pdf
+#
+# The main distinction to keep in mind between 32-bit NEON and AArch64 SIMD is
+# AArch64 cannot compute over the upper halves of SIMD registers. In 32-bit
+# NEON, the low and high halves of the 128-bit register q0 are accessible as
+# 64-bit registers d0 and d1, respectively. In AArch64, dN is the lower half of
+# vN. Where the 32-bit version would use the upper half, this file must keep
+# halves in separate registers.
+#
+# The other distinction is in syntax. 32-bit NEON embeds lane information in the
+# instruction name, while AArch64 uses suffixes on the registers. For instance,
+# left-shifting 64-bit lanes of a SIMD register in 32-bit would be written:
+#
+#     vshl.i64 q0, q0, #1
+#
+# in 64-bit, it would be written:
+#
+#     shl v0.2d, v0.2d, #1
+#
+# See Programmer's Guide for ARMv8-A, section 7 for details.
+# http://infocenter.arm.com/help/topic/com.arm.doc.den0024a/DEN0024A_v8_architecture_PG.pdf
+#
+# Finally, note the 8-bit and 64-bit polynomial multipliers in AArch64 differ
+# only by suffix. pmull vR.8h, vA.8b, vB.8b multiplies eight 8-bit polynomials
+# and is always available. pmull vR.1q, vA.1d, vB.1d multiplies a 64-bit
+# polynomial and is conditioned on the PMULL extension. This file emulates the
+# latter with the former.
