# March 2010
#
# The module implements "4-bit" GCM GHASH function and underlying
# single multiplication operation in GF(2^128). "4-bit" means that it
# uses 256 bytes per-key table [+128 bytes shared table]. Performance
# results are for streamed GHASH subroutine on UltraSPARC pre-Tx CPU
# and are expressed in cycles per processed byte, less is better:
#
# gcc 3.3.x cc 5.2 this assembler
#
# 32-bit build 81.4 43.3 12.6 (+546%/+244%)
# 64-bit build 20.2 21.2 12.6 (+60%/+68%)
#
# Here is data collected on UltraSPARC T1 system running Linux:
#
# gcc 4.4.1 this assembler
#
# 32-bit build 566 50 (+1000%)
# 64-bit build 56 50 (+12%)
#
# I don't quite understand why difference between 32-bit and 64-bit
# compiler-generated code is so big. Compilers *were* instructed to
# generate code for UltraSPARC and should have used 64-bit registers
# for Z vector (see C code) even in 32-bit build... Oh well, it only
# means more impressive improvement coefficients for this assembler
# module;-) Loops are aggressively modulo-scheduled in respect to
# references to input data and Z.hi updates to achieve 12 cycles
# timing. To anchor to something else, sha1-sparcv9.pl spends 11.6
# cycles to process one byte on UltraSPARC pre-Tx CPU and ~24 on T1.
#
# October 2012
#
# Add VIS3 lookup-table-free implementation using polynomial
# multiplication xmulx[hi] and extended addition addxc[cc]
# instructions. 4.52/7.63x improvement on T3/T4 or in absolute
# terms 7.90/2.14 cycles per byte. On T4 multi-process benchmark
# saturates at ~15.5x single-process result on 8-core processor,
# or ~20.5GBps per 2.85GHz socket.
