Abstract
A method of analyzing and optimizing programs by predicting branches and redirecting control flow. A program to be analyzed and optimized is inspected to find branches that might be predictable. A set of assertions is generated, analyzed by a dataflow solver and then used to predict the effects of branches. Control flow in the program is redirected to skip over predictable branches. The dataflow solver is capable of analyzing assertions involving lvalues such as variables, pointer expressions, or components of aggregate lvalues.
