Thanks for writting this down ;) note that the CFG infrastructure also existed in reg-stack.c and flow.c, not only in Haifa. The original idea behind CFG code was to unify those implementations into something more generally useful and one developed by Rth for liveness was taken a as the winner to rule them all. http://www.ucw.cz/~hubicka/papers/proj.pdf has some more historical notes, too ;) Honza > > Ciao! > Steven
