Writing loop transformations on the right representation is more productive
...ncies and disabling the > pass may have side-effects. This applies literally to any pass. I think the problem of reusability is even worse for the current loop optimization passes. We have multiple, partially transformation-specific dependence analyses, such LoopAccessAnalysis, DependenceInfo, LoopInterchangeLegality, etc. Another one is currently in the works. https://xkcd.com/927/ actually does apply here, but I also think that pass-specific dependence analyses do not scale. > > I'd put loop optimizations earlier into the pipeline than vectorization. Where exactly is a phase ordering problem. I...
