Naturally, the more a target customizes codegen preparation, the less DAGCombine can be reused. Yes. That’s CodgeGenPrepare in a nutshell, really. I don’t think anyone claims CGP is a good thing, merely that with our existing infrastructure, it’s a necessary and effective thing. -Jim > > That said, if NSW can be added to SelectionDAG without too many issues, then it may be a moot point. > > -Andy >...
