Hi, I know when a pass needs other passes, it will use something like this: "AU.addRequired<LoopInfo>();". But this is usually used for the analysis passes. When a pass needs another transform pass, can it call it automatically? For example: Some loop optimizations may need loop-simplify, I need add -loop-simplify before calling these passes manually, or they can call the pass
