Also, here is r388 with AVX512 enabled code. I've folded my AVX-ECM implementation into this latest version, which is 1.5x to 2.5x higher throughput than gmp-ecm (so ecm_ext can be set to something like 11000000 again). And SIQS is about 25% faster than the SSE41 version for larger inputs.

Having the same problems with system() calls with this mingw build though, so unfortunately NFS won't work. Let me know if other problems emerge.

I've attached a build of the most recent version with only SSE4.1 activated in yafu. The underlying gmp and ecm builds I believe used -march=k8 and msieve had no special -march
With those caveats, hopefully this works.
I got this:
"The program can't start because msys-2.0.dll is missing..."

It must be something that mingw uses? Not familiar with it.

I put a copy of the version I have in the YAFU mirror.
