Optimizing compiling of object oriented source code

摘要

A method address storage table information, a class information and a function reference information are extracted from an intermediate code and analyzed. When any method determined in execution is not overridden in one of classes by the other class, method address storage tables of the respective classes are deleted and a method address storage table that can be commonly used in the both classes is generated. Then, method address storage table pointers of the both classes are renewed to a leading address value of the generated method address storage table that can be commonly used in the both classes. As described, the method address storage tables redundantly generated in the different classes are deleted so that an object code size can be reduced.
