Also, there is a command line option on bn that allows you to see what your compiler supports (without the need to compile with the option of course)... platform zero means not available, compiled zero means you didn't compile for it.

$ bn -c f:/bn.cfg --hardware
Intrinsics...
arm..... platform:0.
intel... platform:1.
avx512.. platform:0 compiled:0.
avx2.... platform:1 compiled:1.
sse41... platform:1 compiled:1.
shani... platform:0 compiled:0.
neon.... platform:0 compiled:0.

FYI in a recent -system change I removed all of the runtime conditionality, so the builds are not portable but are maximally benefit from hash vectorization. The conditionality is only used now to provide bn command line feedback on the availability of the optimizations.
