------- Comment #100 from bonzini at gnu dot org 2009-06-15 16:22 ------- Just as a reminder for after the fwprop patches are committed, the problem in CFG cleanup is that the iterative fixing of dominators in remove_edge_and_dominated_blocks is very expensive. Probably we should make sure no dominators are there in some key cfgcleanup passes.
