I see this has been resolved based on my understanding of the rest of
the comments in this thread but I figured I would comment on this bit.
You generally do not need a version of LLVM from main (i.e., 20 right
now) to reproduce these reports, it just happens to be the version that
the robot used to flag this issue. I maintain precompiled versions of
stable LLVM releases on kernel.org, which would show this issue with
that same configuration, no building needed :)

https://mirrors.edge.kernel.org/pub/tools/llvm/

If you try the latest version and the problem does not show up, feel
free to comment on the report (which should have llvm@lists.linux.dev in
CC) to let us know and we can see if it is an LLVM main problem (and
bisect it to get it reported and fixed upstream at that point).

Cheers,
Nathan
