# Add NEON implementation featuring polynomial multiplication, i.e. no
# lookup tables involved. On Cortex A8 it was measured to process one
# byte in 15 cycles or 55% faster than integer-only code.
-#
-# April 2014
-#
-# Switch to multiplication algorithm suggested in paper referred
-# below and combine it with reduction algorithm from x86 module.
-# Performance improvement over previous version varies from 65% on
-# Snapdragon S4 to 110% on Cortex A9. In absolute terms Cortex A8
-# processes one byte in 8.45 cycles, A9 - in 10.2, Snapdragon S4 -
-# in 9.33.
