public class FinalUnitOptimize
extends Object

Final agressive filter optimization before code emission. Unroller, Propagate, BlockFlattener, ArrayDestroyer (locals), VarDeclRaiser on each method. ArrayDestroyer (fields, if option set), DeadCodeElimination on the code unit as a whole. Refactored out of cluster, raw, spacedynamic, spacetime backends. Also existed in rstream backend but commented out.
