I hope you've reported that bug the the LLVM people ? Can you please
add a comment in the code and reference the respective bug report
(either commit message or inline is fine).

Please add the following tag so that we get this for stable.
Cc: "12.0 13.0 17.0" <mesa-stable at lists.freedesktop.org>

Thanks !
