Hi the Clang nightly builds are failing on PowerPC with the ppc64e_defconfig. They started failing on Sept 11. Clang is failing on PowerPC in both linux-next and stable so it seems like something changed in Clang and not the kernel.

Unfortunately I don't have ready access to the /tmp/vgetrandom-fef220.c file that was generated, but hopefully these logs are enough to reproduce the issue.

Indeed, thanks a lot for the report. I was able to reproduce this locally, bisect LLVM to find the problematic commit, and report it upstream:

https://github.com/llvm/llvm-project/pull/157206#issuecomment-3313700961

Hopefully it can be resolved quickly.

Cheers, Nathan
