This series of patches add the powerpc64 assembly for modp/redc functions for elliptic curves P192, P224, P256, P384, P521, X25519 and X448. It results in 15-30% performance improvements as measured on POWER9 system using hogweed-benchmark.
Nice. For testing these functions, I recommend running
while NETTLE_TEST_SEED=0 ./testsuite/ecc-mod-test ; do : ; done
and
while NETTLE_TEST_SEED=0 ./testsuite/ecc-redc-test ; do : ; done
for a few hours.
