I assume they update LLVM alongside Mesa. Ubuntu 18.10 is likely to ship LLVM 6, but around the same timeframe I plan to drop LLVM 6 support. We'll have to bump the LLVM version for future chips anyway. Right now, any change around SGPR pointers requires 4 piglit runs to check for regressions: (VI + GFX9) * (LLVM6 + LLVM7). The chance that some of those will get broken horribly is very high.
