@aeubanks An interesting idea.  I'll give it some thought... it should be doable by combining this with the logic in the change printers but I'd be concerned that the detection of the changes would become a hotspot itself.  Perhaps a double run, the first to determine which passes make changes and then a recompile to time those passes that are then known to make changes.
