-# SHA256/512 for ARMv8.
-#
-# Performance in cycles per processed byte and improvement coefficient
-# over code generated with "default" compiler:
-#
-# SHA256-hw SHA256(*) SHA512
-# Apple A7 1.97 10.5 (+33%) 6.73 (-1%(**))
-# Cortex-A5x n/a n/a n/a
-#
-# (*) Software SHA256 results are of lesser relevance, presented
-# mostly for informational purposes.
-# (**) The result is a trade-off: it's possible to improve it by
-# 10%, but at the cost of 20% loss on Cortex-A5x.
