    Note that this bug is the same with both gas and AS=clang, which also
    indicates that clang implemented the undocumented .rep directive
    for compatibility.

    Overall I think we are at the point where building the kernel with clang-8
    is mature enough that we should work around bugs like this where it is
    easy enough rather than waiting for clang-9.
