Class DeadCode

java.lang.Object
  harpoon.Analysis.Quads.DeadCode

public abstract class DeadCode
extends Object

DeadCode removes dead code (unused definitions/useless jmps/one-argument phi functions/all moves) from a method. The analysis is optimistic; that is, it assumes that all code is unused and seeks to prove otherwise. Also works on LowQuads.
