0:0(0): error: no matching function for call to `texelFetch2DOffset(sampler2D, ivec2, int, ivec2)'

I was seeing these errors before, but I no longer am. Does it help if you launch Tropics something like:

force_glsl_extensions_warn=true disable_blend_func_extended=true ./1024x768_windowed.sh

(In reply to comment #3)

Tropics: SIInstrInfo.cpp:94: virtual void llvm::SIInstrInfo::copyPhysReg(llvm::MachineBasicBlock&, llvm::MachineBasicBlock::iterator, llvm::DebugLoc, unsigned int, unsigned int, bool) const: Assertion `AMDGPU::SReg_32RegClass.contains(SrcReg)' failed.

Tom's LLVM patch fixes this.
