Tomb Raider's crash is caused by the following error:
"LLVM ERROR: branch size exceeds simm16"

Reverting relevant LLVM commit [1] workarounds this issue, however running Tomb
Raider at Ultra settings completely hangs the GPU. Other settings works fine.

Another issue is the following warning which appear when running any GL app:
"Warning: LLVM emitted unknown config register: 0x4"

So yes, as Michel said, mesa-12.0 doesn't fully support llvm-3.9.
