[PATCH] D99249: [PassManager] Run additional LICM before LoopRotate

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added inline comments.


================
Comment at: llvm/lib/Passes/PassBuilder.cpp:579
   // TODO: Investigate promotion cap for O1.
   LPM1.addPass(LICMPass(PTO.LicmMssaOptCap, PTO.LicmMssaNoAccForPromotionCap));
   LPM1.addPass(SimpleLoopUnswitchPass());
----------------
Theroretically LICM should move all invariants out of loop, and loop rotation should not create any new invariants. Do we really need this again?
