The problem of finding dominators in a flowgraph arises in many kinds of global code optimization and other settings. In 1979 Lengauer and Tarjan gave an almost-linear-time algorithm to find dominators. In 1985 Harel claimed a linear-time algorithm, but this algorithm was incomplete; Alstrup et al. [1999] gave a complete and “simpler ” linear-time algorithm on a random-access machine. In 1998, Buchsbaum et al. claimed a “new, simpler ” linear-time algorithm with implementations both on a random access machine and on a pointer machine. In this paper, we begin by noting that the key lemma of Buchsbaum et al. does not in fact apply to their algorithm, and their algorithm does not run in linear time. Then we provide a complete, correct, simpler...
