Well, what about For each available function FOR_EACH_BB_FN (function). At least that was my plan. You are probably going to do other things to the functions than just walking the CFG (looking into variables/SSA names etc) and thus way you won't get crash either. But I don't have strong feeling here, both alternatives seems OK for me.
