Jan Hubicka <hubicka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hubicka at gcc dot gnu.org --- Comment #15 from Jan Hubicka <hubicka at gcc dot gnu.org> --- loop splitting gives up here because it only handles test i < val or i > val Not i = val. It could easily work out that i == 0 is same as i < 1 from vlaue range of i.
