WebOct 31, 2012 · a tree with a vertex order, verifies that the order is low-high and that the tree is the dominator tree of the flow graph. We present an algorithm that, given a flow graph and its dominator WebInitially, each node’s dominator set is set to the set of all nodes. We add the start node to our worklist. For each node on the worklist, we reevaluate its dominator set. If the set changes, the updated dominator set is used, and all the node’s successors are added to the worklist (so that the updated dominator set can be propagated). krishoba academy youtube channel https://mobecorporation.com
