I have to say the problem is not obvious to me here, so maybe saveIP/restoreIP should be changed (or eliminated in favor of always using InsertPointGuard). I'm not seeing a lot of places where saveIP/restoreIP are used.
Yeah, not too many. I'm not seeing any real reason not to just switch Clang over to always use InsertPointGuard. (Yaxun, you don't need to do this; I'm just making a note to myself.)
