In the past, such problems were sometimes caused by llvm snafu. Can you set GALLIVM_DEBUG="nopt" and try again?

Failure fixed. Patches sent upstream.
Patches are now upstream: https://gitlab.freedesktop.org/mesa/mesa/compare/1f6b92b47652e7f48f03ef6a4228a19537022d23...70a7ece035785978167fe0019b6ff603415b1f3b I think it's borderline whether they should be backported to 18.3.x. Not sure. They'll be in 19.0.0 regardless.
Did I understand that right that very likely this also helps with tiled rendering performance on top of Aarch64 for freedreno and the likes? Regarding backporting - I would prefer if the next stable target wouldn't fail tests, but I can try my best to ignore this particular test failure for one more stable cycle.

That's what I thought, but I think I was wrong after looking at the code again. > Regarding backporting - I would prefer if the next stable target wouldn't > fail tests, but I can try my best to ignore this particular test failure for > one more stable cycle. I know it'll be a burden...
Should be fixed in the 19.0.0 rcs. Not planning to do anything else here.
