Yes! Try ./autogen.sh -yaksa-depth=2. You can try -yaksa-depth=1 if 2 is still too slow.

Subject: [mpich-devel] is there a way to speedup build related to yaksuri?

Is there a configure option that would allow me to avoid the compilation bottleneck in `src/backend/seq/pup/yaksuri_seqi_pup*`? I want to rebuild MPICH frequently for development purposes, and I do not care about datatype performance in this context.

Some of the yaksuri objects take seconds to compile with GCC 11 at -O2 on Tiger Lake core, and there are hundreds of them.

Thanks,

Jeff
