--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-01-18 13:49:18 UTC --- cleanup_all_empty_eh is called just once per ehcleanup pass, doesn't iterate. If we don't want to iterate on the new pads, we could just use len = VEC_length too, but IMHO some iteration is helpful, as we don't recurse on them, and we probably want to handle cases like moving pads across two empty bbs and with a resx in the third bb or something similar.
