Class Optimization

java.lang.Object
  ic.opt.Optimization

public abstract class Optimization
extends Object

To create an optimization, simply subclass this class and define optimize(md) to compute any dataflow information necessary to perform the optimization on md and then modify the method's TAC list. You can either provide methods in your TACList class to modify an existing list, or you can construct a new list to replace the old one. The methods return true to indicate that the optimization changed the TAC in some way. While not required, you can provide a -iter command-line option that iterative applies all optimizations over and over again until no additional changes happen.

Method Detail

optimize

public boolean optimize(ic.ast.Program p)

Apply the optimization to each Method in p. Return true if the TAC for any of them changed.

public abstract boolean optimize(ic.ast.MethodDecl md)

Apply the optimization to the method md. Return true if the TAC for the method changes at all.
