I have some sympathy for going in Alexandre's direction, in that it would be nice to have a mode that provided optimization as well as accurate debugging. However, since preserving accurate debug information has a cost, I think it would be better to turn -O1, not -O2, into the mode that Alexandre wants, where debug information is preserved. Trying to rework all optimizations to keep perfect debug information is going to take forever and make the compiler worse.
