> Yeah, right. Even for SM6 the current code is likely to produce bad results, because AFAIU many signature elements can be merged in a single one using `register_count`. I think the appropriate action right now is to emit the signature only for SM4-5, and leave the rest to the future if the need will arise. I will submit a MR for that.
