--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
fwprop already calculates dominance info and frees it as well. It invalidates
it via calling purge_dead_edges. It also calls cleanup_cfg twice for no good
reason (in fwprop_done and after it).
As dominance calculation does a verify-dominance info dom info should be
up-to-date there. freeing it before fwprop can't fix anything.
