------- Comment #12 from jakub at gcc dot gnu dot org 2010-01-28 15:11 ------- So not call df_set_bb_dirty in df_insn_rescan if DEBUG_INSN_P (insn), or not mark dirty only certain problems? I believe DEBUG_INSNs aren't meant to extend lifetime of pseudos, so perhaps lr/live problems don't need to be marked dirty, what about others?
