We split the dominance tree by removing the immediate dominator - edges from BBS, creating a forrest F. We form a graph G whose vertices + edges from BBS, creating a forest F. We form a graph G whose vertices are BBS and ENTRY and X -> Y is an edge of G if there exists an edge - X' -> Y in CFG such that X' belongs to the tree of the dominance forrest + X' -> Y in CFG such that X' belongs to the tree of the dominance forest whose root is X. We then determine dominance tree of G. Note that for X, Y in BBS, X dominates Y in CFG if and only if X dominates Y in G. In this step, we can use arbitrary algorithm to determine dominators. |
