This is hard to do with perl’s extended regular expressions, which are considerably more powerful than anything in C++. I suggest a different tack: First get rid of the things that don’t look like functions such as data (look for the D designator). Stuff like virtual thunk to this, virtual table for that, etc., will … Read more
