--- Comment #5 from Ilya Enkovich <ienkovich at gcc dot gnu.org> --- (In reply to Richard Biener from comment #3) > fwprop_init calcuates dominator info so it's likely df that runs cfg-cleanup > and doesn't expect it to wreck dominator info. > > Probably rightfully so. So should we improve cse_cfg_altered computation taking cfg_cleanup calls into account or free dominance info in cfg_cleanup instead?
