What about "mcount" (i.e. no underscore)?
I don't think it works since such regex doesn't match to "CALL26 _mcount".
What I meant was, do you need to match "mcount" as well? However, after speaking to our GCC guys, they say they only support "_mcount" (preferred) and "__mcount" (which GCC itself doesn't emit) so you can leave this regex as-is.
