Abstract
A fast and efficient way of performing global value numbering beyond basic blocks and extended basic blocks on a complete topological ordering of basic blocks in a program. Global value numbering makes use of an unknown value number and iterative processing of a worklist containing expressions assigned an unknown value number. A hash table is used to reduce storage and processing time.
