================
Comment at: lib/Transforms/Utils/SimplifyIndVar.cpp:553
+  // If I is the LCSSA phi, L will not contain UserL, skip I in this case
+  if (!L->contains(UserL))
+    return false;
----------------
Maybe we should not push IV users in pushIVUsers at all if IV users do not in the IV loop (e.g. LCSSA phi)
