WebPartial-Redundancy Elimination Minimize the number of expression evaluations By moving around the places where an expression is evaluated and keeping the result in a temporary variable when necessary, we often can reduce the number of evaluations of this expression along many of the execution paths, while not increasing that number along any path … WebTrue partial redundancy: an expression is sometimes available, sometimes not. , u U P Convention Throughout, assume that neither argument of an expression x+y is modified …
WebPartial Redundancy Elimination (PRE) is a global, powerful optimization technique first developed by Morel and Renvoise and discussed in [27,6]. PRE generally results in removing partially redundant expressions, and hoisting loop-invariant expressions. Unlike many other optimization algorithms, PRE doesn't need to distinguish between global and ...
