LLVM assembly of shader
The attached shader (LLVM assembly, dumped with R600_DEBUG=ps) fails to compile
with latest LLVM trunk. AFAIR it worked at some point with some combination of
Mesa and LLVM, but I couldn't reproduce this.
Compile with
> llc -march=amdgcn -mcpu=SI -mattr=+vgpr-spilling -verify-machineinstrs < bug.ll
to reproduce. It looks like it is spilling related.
