That was the usual side-effect - I wonder if we want to emit extra diagnostic when one of the obsolete options is given but -g is not enabled in the end or whether we want to preserve the debug info enablement effect? > > > > Please followup with a gcc-13/changes.html entry. > > Sure. > > > > > I notice we have VMS_DEBUGGING_INFO left.

Well, VMS debugging would go, just like STABS. With "free-form" I mean that frontend code could call into the dwarf2out API directly, creating DWARF DIEs for language specific info (we probably want to export more and/or nicer APIs for such use).
