Agree with you, however as find_duplicates operates BB by BB, it would require introduction of some kind of dependencies (e.g. you can merge BB1 with BB2, if BBx would be merged with BBy). I can write it on my TODO list after we'll transform tail-merge to IPA ICF infrastructure. Does it work for you? Martin > > Thanks, > Richard. > >> Martin
