Hi Andrii,

Downloaded tarball for kernel release 5.5.4, and I cannot compile
tools/testing/selftests/bpf/ with latest LLVM release version 9.  

Is this something that recently broke?  If so, what commit caused it?

Digging through, it seems several commits.

'git bisect' is your friend here, can you please use it?

And has llvm 9 always worked here?

Yes, llvm-9 used to work for tools/testing/selftests/bpf/.

As of when?

thanks,
