--- Comment #40 from Daniel Scharrer <daniel at constexpr.org> ---
It's still reproducible in Painkiller H&D with LLVM r202464 (ie. current
trunk).

While some previously broken PP effects now work, dynamic lighting is still
messed up and there's plenty of this in the log:

LLVM triggered Diagnostic Handler: SIInstrInfo::storeRegToStackSlot - Can't
spill VGPR!
LLVM triggered Diagnostic Handler: SIInstrInfo::loadRegToStackSlot - Can't
retrieve spilled VGPR!
