Hmm if a segment had a list of its //child// segments, then couldn't layout be done recursively on each child segment? Would this not be more straight forward?
I think what I currently have should move more in the direction you are suggesting. I have a concern with my current implementation, its if I should use the original program headers or the updated ones. It's possible to change a segments vaddr, although you have mentioned unlikely. This would be problematic to use `sectionInSegment` after changing the program headers because then it would be obviously wrong. So right now I use the original program headers. Also something to look out for, I use parent segments as indexes not pointers and those are `ssize_t` not `size_t` because the alternative of using one past the last segment like an end iterator was too ugly than using -1 to denote no parent. I could also use size_t's max I suppose.
