--- Comment #7 from Alex Deucher agd5f@yahoo.com --- There are some asic specific shader instruction behaviors for r6xx/r7xx chips that need to be ported to the LLVM backend. A couple that come to mind: - Trig functions (see tgsi_setup_trig() in r600_shader.c) - AR register handling (see load_ar() in r600_asm.c)
