Hi, I noticed that the dead instructions collected when build vplan are invariant to different ranges of VFs since the original loop is not changed. Maybe DeadInstructions should be treated as a data member of LoopVectorizationPlanner and initialized by collectTriviallyDeadInstructions() in plan()?
