Thanks for the report. This is a known issue that we have been tracking
and it is now resolved in LLVM 14:
https://github.com/ClangBuiltLinux/linux/issues/1438
Nick said he should have a kernel patch to work around this in the
kernel for older versions of LLVM soon.
By the way, can you use our new mailing list and my kernel.org address
for future reports (llvm@lists.linux.devi, nathan@kernel.org)? It will
make it easier to find these reports in the archives in the future and
my filters will catch this better.
Cheers,
Nathan
