A Simple Algorithm for Partial Redundancy Elimination

Paleri, VK, Srikant YN, Shankar P.  1998.  A Simple Algorithm for Partial Redundancy Elimination. SIGPLAN Notices. 33:35-43., Number 12


The paper proposes a new algorithm for partial redundancy elimination based on the new concepts of safe partial availability and safe partial anticipability. These new concepts are derived by the integration of the notion of safety into the definitions of partial availability and partial anticipability. It is both computationally and lifetime optimal and requires four unidirectional analyses. The most important feature of the algorithm is its simplicity; the algorithm evolves naturally from the new concept of safe partial availability.
