foad added a comment.
Makes sense to me, but I don't understand what the implications might be. For example, this pass will now unconditionally run a LoopSimplify pass. Previously could it have relied on an earlier LoopSimplify run, if all the intervening passes "preserved" LoopSimplify?
To put it another way: does this patch slow down the compiler? And/or does it add more passes to the list reported by -debug-pass=Structure, for a typical compile?
