Thanks for confirming. Btw is it the case that you want to perform bulk copies with byte-swapping for arbitrary sizes? E.g. you want to swap bytes for entire structs? I guess I'm not super sure of what is your real use case (e.g. the reason as to why just copying bytes from one segment to another is not enough). For instance, if you want to bulk copy arbitrary structs, adjusting for endianness is not simple at all - as you would have to swap each field individually.
