214 "execution" of the Phi operation requires "remembering" which block
215 control came from. The Phi operation takes on the value corresponding to
227 Phi nodes:
231 Phi node in this case.
237 can insert Phi nodes directly, if convenient. In this case, it is really
238 really easy to generate the Phi node, so we choose to do it directly.
292 * phi. We create a new name because one is used for the phi node, and the
305 issue is that when we create the Phi node in the merge block, we need to
306 set up the block/value pairs that indicate how the Phi will work.
307 Importantly, the Phi node expects to have an entry for each predecessor
314 value for code that will set up the Phi node.
