Created attachment 114655 [details] 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.
