Hi, I am trying to add Hazard scheduling nodes after buildSchedGraph(), with a scheduler derived from ScheduleDAGInstrs. I get weird errors, so I wonder what I am doing wrong? What I am doing right now is: I have a created MI with opcode HAZARD that does not have parent, and I greate a SUnit(HazardMI). I use this one HazardMI for all hazard nodes. I remove all edges using removePred. I insert edges between Node -> hazardNode -> pred. What is there to think about in this approach? I must be missing some detail... Any help is appreciated, Jonas Paulsson -------------- next part --------...
