USE_BMI2=1 did solve the compilation issue, so thank you for that!
I am also encountering the issue when running tune() with the second siqs number: Code:

One has to admit that this naming scheme was not very evident; the one for Intel Core i is much more understandable (excluding some oddities like recent mobile CPUs etc.).

Problem in tune() fixed.
Also fixed an issue in microecm when compiling with gcc (verified it works now with gcc11.1.0). Rebuilt and reuploaded the windows executables.

New build of regular version completed tune fine on my i38100, and it's still running on my i73930K.
I do notice that the 3930K is embarrassingly slow in some cases, perhaps there's a fallback codepath due to lack of hardware features. For example, SIQS on c90 42735....7841 ran at 1135 rel/s on my i3, and is currently running at 3.26 on my 3930K. That's 350x slower, is that sane and/or expected?

GNFS also runs with one thread. Even with lathreads=8

As far as I know, YAFU has no GPU capability.
