GCC doesn't implement a multiple entry-points strategy. I wish it did :-) Instead we used cloned functions with slightly different calling sequences. I can see no reason why either the multiple entry-points or cloning approach would have a problem with recursion, though. > I think people have raised this before but some targets will never > support multiple entry points.
