-# Fixed length (n=6), unrolled PPC Montgomery Multiplication
-#
-
-# 2021
-#
-# Although this is a generic implementation for unrolling Montgomery
-# Multiplication for arbitrary values of n, this is currently only
-# used for n = 6 to improve the performance of ECC p384.
-#
-# Unrolling allows intermediate results to be stored in registers,
-# rather than on the stack, improving performance by ~7% compared to
-# the existing PPC assembly code.
-#
-# The ISA 3.0 implementation uses combination multiply/add
-# instructions (maddld, maddhdu) to improve performance by an
-# additional ~10% on Power 9.
-#
-# Finally, saving non-volatile registers into volatile vector
-# registers instead of onto the stack saves a little more.
-#
-# On a Power 9 machine we see an overall improvement of ~18%.
