cpuminer-opt-3.18.1
More speed for scrypt:
- additional scryptn2 optimizations for all CPU architectures,
- AVX2 is now used by default on CPUS with SHA but not AVX512,
- scrypt:1024 performance lost in v3.18.0 is restored,
- AVX512 & AVX2 improvements to scrypt:1024.
Big speedup for SwiFFTx AVX2 & SSE4.1: x22i +55%, x25x +22%.
Issue #337: fixed a problem that could display negative stats values in the first summary report if the
report was forced prematurely due to a stratum diff change. The stats will still be invalid but should
display zeros.
