I've checked, and LoopInfo is always available in pipeline positions where GVN runs, so this effectively has no impact. I've made it a required analysis for the NewPM as well in https://github.com/llvm/llvm-project/commit/fa5884770ab240139f33a8b2be801673ca21b9c0. https://github.com/llvm/llvm-project/pull/65729 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
