A data flow analysis algorithm for computing dominators
Nan Jiang

This entry formalises the fast iterative algorithm for computing dominators due
to Cooper, Harvey and Kennedy. It gives a specification of computing dominators
on a control flow graph where each node refers to its reverse post order number.
A semilattice of reversed-ordered list which represents dominators is built and
a Kildall-style algorithm on the semilattice is defined for computing
dominators. Finally the soundness and completeness of the algorithm are proved
w.r.t. the specification.
