[PATCH] D87957: [LoopReroll][NewPM] Port -loop-reroll to NPM

[Alina Sbirlea via Phabricator via llvm-commits]

asbirlea added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/LoopRerollPass.cpp:1726
+  return LoopReroll(&AR.AA, &AR.LI, &AR.SE, &AR.TLI, &AR.DT, true).runOnLoop(&L)
+             ? PreservedAnalyses::none()
+             : PreservedAnalyses::all();
----------------
Isn't anything preserved? LCSSA and AA perhaps?
AFAICT, getLoopPassPreservedAnalyses() does not apply; DT, LI and ScEv are not preserved.
