There is certainly C&P involved for the three variations (div, mod,
div/mod) as they all share the same core algorithm with minor
variations. I can't say anything about the working state of the idiv
path as I don't have any hardware for that. I remember asking for
testers of that. The code was carefully tested for the non-idiv
branches.
