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.

The sse4 and avx2 options cut CPU by 4x and 8x respectively for merkle root computations. avx512 would be 16x.
