The paper studies some characteristics of post dominator trees. These results can form the basis for the development of a more efficient construction algorithm.
A program can be represented by a control flow graph, which consists of a set of nodes and a set of edges. Each node represents a block of statements.
The concepts of post dominators and post dominator trees are extensively used in code optimisation (J. Ferrante et al., 1987), program slicing (H. Agrawal ...
