--- Comment #6 from Nicolai Hähnle nhaehnle@gmail.com --- Hi John, that precise LLVM revision doesn't exist (or rather, it's not a change in LLVM itself), and the commits around it don't look obviously related. Did you arrive there by a bisect?
You could help by providing the output when running with R600_DEBUG=ps,vs,tcs,tes,gs.
