--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- Hmm. We return signed offset because the maximum object size is half of the address space. So I think the code is OK and just invalid C input will produce undefined output here. Otherwise we'd need one bit more in precision and sacrifice speed of compilation quite a bit for this hot function.
