I guess that's true for the middle-end in non-LTO mode at this point. But then the new approach shouldn't be make correctness depend on its setting in the front-ends, that's too error-prone IMO. > I propose to add semantics for it. Fine with me, as long as it's centralized somewhere in the middle-end. -- Eric Botcazou
