# 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]. On PA-7100LC
# it processes one byte in 19.6 cycles, which is more than twice as
# fast as code generated by gcc 3.2. PA-RISC 2.0 loop is scheduled for
# 8 cycles, but measured performance on PA-8600 system is ~9 cycles per
# processed byte. This is ~2.2x faster than 64-bit code generated by
# vendor compiler (which used to be very hard to beat:-).
