Not sure I understand the question (sorry I missed this comment when it was made). The suggestion is that for our target, clang sets explicit alignment, so LLVM should not need to know where optsize came from. LLVM's handling of optsize will not reset an alignment that is already set. Is there a situation where the wrong thing still happens?
