--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That doesn't look correct, that will not clear done on any basic block that has
abnormal successor with ABNORMAL_DISPATCHER, which is a lot of basic blocks. 
If the algorithm isn't supposed to follow abnormal edges, then it shouldn't
follow them, not have some hack for the abnormal dispatcher.
