But, the way the ABI works requires a reference from each unit which may cause unwinding. Even if you lose the personality routine, you will still have the exception tables, which themselves are a significant cost. If you don't want to pay for exceptions, you really have to compile with -fno-exceptions. In that case, certainly, we should be able to avoid pulling in the personality routine.
I think that we are actually in agreement, for the most part. The routines which need unwinding should have a reference to the personality module. Routines which don't need unwinding shouldn't have a superfluous reference to it. There is a check in doing_eh() in except.c which checks that -fexceptions is set if any exception-specific functions are used. It seems that this would be the place to generate the reference to __gxx_personality_v0. -- Michael Eager [EMAIL PROTECTED] 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
