It is still a work in progress at this point, but it produces working and reasonably well-optimized code. Originally based on ir_to_mesa and st_mesa_to_tgsi, but does not directly use Mesa IR instructions in TGSI generation, instead generating TGSI from the intermediate class glsl_to_tgsi_instruction. It also has new optimization passes to replace _mesa_optimize_program.
