Method for improving irreducible region commoning compile speed

摘要

A method for improving compile speed in irreducible code regions within a computer program is disclosed. The method comprises determining which of a plurality of code regions within a computer program is irreducible, determining an influence of the irreducible code on blocks within code regions, determining a direction of processing based on the influence of the irreducible code on adjacent blocks and performing a processing based on a current direction of processing and the determined direction of processing.
