I suspected a problem in how volatile with non-present output args could
be different, but this seems not to be the case.

I would contact llvm/clang mailing list and ask. Maybe there is a
problem? It seems kind of strange to me...

+1

Do you really think this is a compiler issue?

If clang/LLVM advertises "GCC compatibility", then this would
certainly be a different behavior.

As you wish. I will contact the clang folks. As the proposed fix is not super
urgend, I think we can leave it until I got word from clang.

Okay, that would be good, please let us know.

I believe there's certainly effort in the direction of an official
kernel clang/LLVM support, but not officially supported yet. If we
could get some clarification on the issue, even better.
