METHOD AND APPARATUS FOR MANAGING VARIABLE ASSIGNMENTS IN A PROGRAM

摘要

The illustrative embodiments described herein provide a computer-implemented method, apparatus, and computer program product for managing variable assignments in a program. The process identifies a set of variable assignments that is live on a portion of paths to form a set of identified variable assignments. Each of the set of identified variable assignments assign a value to at least one variable of a set of variables. The process determines a set of program points at which the set of identified variable assignments is live on all paths. The process also moves the set of identified variable assignments to the set of program points in response to determining that the set of identified variable assignments is movable to the set of program points.
