Mesa compiles GLSL code with its own compiler. It produces an IR which is then translated into several different instructions sets depending on the driver. LLVM is not involved in this. For OSMesa, the IR is translated into Mesa internal GPU-like instruction set which is executed with a simple interpreter. -Brian
