[Mesa-dev] [PATCH] radv: setup llvm target data layout
From: Dave Airlie Ported from radeonsi, pointed out by Tom. "This prevents LLVM from using sext instructions for local memory offsets and allows the backend to fold immediate offsets into the instruction. This also prevents some incorrect code generation for ptrtoint and inttoptr instructions."
