Compared to the current version in master branch, this version definitely improves the performance of the reduction code.
On POWER9, the reduction code shows 7% speed up when tested separately.
The improvement in P256 sign/verify is marginal. Here are the numbers from hogweed-benchmark on POWER9.
name size sign/ms verify/ms ecdsa 256 11.1013 3.5713 (master) ecdsa 256 11.1527 3.6011 (this patch)
Thanks for testing. Committed to the master branch now.
