Bug ID: 89784
Summary: Complex shader compilation fails (spilling related?)
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: greg@chown.ath.cx

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.
