Not clang related but inquiry sent since this seems to require knowledge of the architecture/hardware: https://lore.kernel.org/linuxppc-dev/20200413201034.GA18373@ubuntu-s3-xlarge-x86/

This has not been fixed but given that it is not a clang specific issue, it has never resurfaced from 0day, and the maintainer indicated that these are pretty old files, I am going to close this up.

$ curl -L https://groups.google.com/group/clang-built-linux/attach/180fe4e504b92/.config.gz\?part\=0.1 | gunzip > .config
$ ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- make CC=clang -j71 olddefconfig
$ ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- make CC=clang -j71 arch/powerpc/platforms/embedded6xx/mvme5100.o

still reproducible.

I am going to close this up.
