For define_insn you can use the -da option, and scan the debug files for the matched insn names. For define_expand you can reliably use profiling information to look for calls to gen_NAME. This approach won't tell you whether you are testing all alternatives of all define_insns. I don't know of a reasonable way to do that. Ian
