protected int doOpcode(int pos, byte[] code) throws BadBytecode Does abstract interpretation on the given bytecode instruction. It records whether or not a local variable (i.e. register) is accessed. If the instruction requires that a local variable or a stack element has a more specific type, this method updates the type of it. Parameters pos:int the position of the instruction. Returns:int the size of the instruction at POS.
