public abstract class MaxMunchCG
extends CodeGen

MaxMunchCG is a MaximalMunchCGG specific extension of CodeGen. Its purpose is to incorporate functionality common to all target architectures but specific to the particular code generation strategy employed by the CGG. Other CodeGeneratorGenerator implementations should add their own extensions of CodeGen.
