Abstract
Optimizing program code in a static compiler by determining the live ranges of variables and determining which live ranges are candidates for moving code from the use site to the definition site of source code. Live ranges for variables in a flow graph are determined. Selected live ranges are determined as candidates in which code will be moved from a use site within the source code to a definition site within the source code. Optimization opportunities within the source code are identified based on the code motion.
