I don't recall which alpha I've tested it last on, but I'm pretty sure it used to work (against LLVM 16). I'm getting the same result on main as of7c87ce7.
This is Gentoo Linux amd64.
I've reproduced by doing (in git repo):
export PATH=/usr/lib/llvm/18/bin:${PATH}./configure --enable-experimental-jitmakeResulting log (70k):python-log.txt
CPython versions tested on:
3.13, CPython main branch
