Class LoadedFieldSet

public class LoadedFieldSet extends Object

Object which stores which fields are loaded and stored by the instructions in a method (including through inner-class access methods), and also which fields are loaded/stored by the overall method. The main purpose is for doing redundant load elimination and forward substitution more efficiently, but it might be useful in other situations.
