The lack of understanding may eventually come back to bite you later. FWIW i did some tests and I don't see noclone affecting frame pointer with gcc 8. The only thing I saw was that empty functions ended up without frame pointer. I suspect you'll need to fix up the other users of noclone too. -Andi
