Could you try to run failing tblgen invocation via gdb and see what signal it gets hit with?
I just reproduced it on Ryzen 3700x, with march=goldmont-plus + emerge --buildpkgonly llvm. @mgorny, can you try to reproduce it locally?
No, I'm taking some time off from hard work.
Same issue on a Intel Pentium N3700 (Airmont architecture) luigi
I faced the same issue with llvm-11.0.0 ciao luigi
