...incoming values from inside the region, while subsequent PHI nodes have inputs from outside? Is that possible? 2. Oddly, later in the code, it creates a corresponding new PHI node in the newBB for each PHI in the old header block. And then it adds the old PHI node as an incoming value to the newPHI node. This is Okay for the first PHI node of original header as it's been proved to have multiple inputs from outside the region earlier. But it does not make sense for subsequent PHI nodes since they may contain only incoming values from inside. Then what's the point of adding it a...
