duke@435 | 52 | // points are defined in the platform-specific inner class. |
duke@435 | 53 | // |
duke@435 | 54 | // Class scheme: |
duke@435 | 55 | // |
duke@435 | 56 | // platform-independent platform-dependent |
duke@435 | 57 | // |
duke@435 | 58 | // stubRoutines.hpp <-- included -- stubRoutines_<arch>.hpp |
duke@435 | 59 | // ^ ^ |
duke@435 | 60 | // | | |

duke@435 | 66 | // stubRoutines_<os_arch>.cpp |
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 |
