--- Comment #7 from Jeffrey A. Law <law at redhat dot com> --- But replacement with the most dominating name (presumably a default def dominates everything) isn't going to help here. In many ways we'd be better off if we didn't propagate from those equality comparisons -- unless they allowed some other later simplification. But we don't have a good way to make that determination. Which ultimately let to the uncprop pass which we run very late to try and put things back the way they were. I wonder if running uncprop between DOM1 & the late unroller would be worth the extra pass. And if so, where does it make the most sense.
