SHA support on AMD Ryzen CPUs requires gcc version 5 or higher and
openssl 1.1.0e or higher. Add one of the following to CFLAGS for SHA
support depending on your CPU and compiler version:
openssl 1.1.0e or higher.
"-march=native" is always the best choice
znver1 and znver2 should be recognized on most recent version of GCC and
znver3 is expected with GCC 11. GCC 11 also includes rocketlake support.
In the meantime here are some suggestions to compile with new CPUs:
"-march=znver1" for Ryzen 1000 & 2000 series, znver2 for 3000.
"-march=native" is usually the best choice, used by build.sh.
"-msha" Add SHA to other tuning options
"-march=znver2 -mvaes" can be used for Ryzen 5000 if znver3 is not recongized.
"-mcascadelake -msha" or
"-mcometlake -mavx512 -msha" can be used for Rocket Lake.
Features can also be added individually:
"-msha" adds support for HW accelerated sha256.
"-mavx512" adds support for 512 bit vectors
"-mvaes" add support for parallel AES

Change Log
----------
v3.18.1
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.
v3.18.0
Complete rewrite of Scrypt code, optimized for large N factor (scryptn2):
- AVX512 & SHA support for SHA256, AVX512 has priority,
- AVX512 & SHA support for sha256, AVX512 has priority,
- up to 50% increase in hashrate,
- memory requirements reduced 30-60% depending on CPU architecture,
- memory usage displayed at startup,
