-# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL

-# CRYPTOGAMS licenses depending on where you obtain it. For further

-# April 2007.

-# Performance improvement over vanilla C code varies from 85% to 45%
-# depending on key length and benchmark. Unfortunately in this context
-# these are not very impressive results [for code that utilizes "wide"
-# 64x64=128-bit multiplication, which is not commonly available to C
-# programmers], at least hand-coded bn_asm.c replacement is known to
-# provide 30-40% better results for longest keys. Well, on a second
-# thought it's not very surprising, because z-CPUs are single-issue
-# and _strictly_ in-order execution, while bn_mul_mont is more or less
-# dependent on CPU ability to pipe-line instructions and have several
-# of them "in-flight" at the same time. I mean while other methods,
-# for example Karatsuba, aim to minimize amount of multiplications at
-# the cost of other operations increase, bn_mul_mont aim to neatly
-# "overlap" multiplications and the other operations [and on most
-# platforms even minimize the amount of the other operations, in
-# particular references to memory]. But it's possible to improve this
-# module performance by implementing dedicated squaring code-path and
-# possibly by unrolling loops...
-
-# January 2009.
-#
-# Reschedule to minimize/avoid Address Generation Interlock hazard,
-# make inner loops counter-based.
