duke@435	67	//
duke@435	68	// Note 1: The important thing is a clean decoupling between stub
duke@435	69	// entry points (interfacing to the whole vm; i.e., 1-to-n
duke@435	70	// relationship) and stub generators (interfacing only to
duke@435	71	// the entry points implementation; i.e., 1-to-1 relationship).
duke@435	72	// This significantly simplifies changes in the generator
duke@435	73	// structure since the rest of the vm is not affected.
duke@435	74	//
duke@435	75	// Note 2: stubGenerator_<arch>.cpp contains a minimal portion of
duke@435	76	// machine-independent code; namely the generator calls of
duke@435	77	// the generator functions that are used platform-independently.
duke@435	78	// However, it comes with the advantage of having a 1-file
duke@435	79	// implementation of the generator. It should be fairly easy
duke@435	80	// to change, should it become a problem later.
duke@435	81	//
duke@435	82	// Scheme for adding a new entry point:
duke@435	83	//
duke@435	84	// 1. determine if it's a platform-dependent or independent entry point
duke@435	85	// a) if platform independent: make subsequent changes in the independent files
duke@435	86	// b) if platform dependent: make subsequent changes in the dependent files
duke@435	87	// 2. add a private instance variable holding the entry point address
duke@435	88	// 3. add a public accessor function to the instance variable
duke@435	89	// 4. implement the corresponding generator function in the platform-dependent
duke@435	90	// stubGenerator_<arch>.cpp file and call the function in generate_all() of that file
