| 62 // Note 1: The important thing is a clean decoupling between stub | |
| 63 // entry points (interfacing to the whole vm; i.e., 1-to-n | |
| 64 // relationship) and stub generators (interfacing only to | |
| 65 // the entry points implementation; i.e., 1-to-1 relationship). | |
| 66 // This significantly simplifies changes in the generator | |
| 67 // structure since the rest of the vm is not affected. | |
| 68 // | |
| 69 // Note 2: stubGenerator_<arch>.cpp contains a minimal portion of | |
| 70 // machine-independent code; namely the generator calls of | |
| 71 // the generator functions that are used platform-independently. | |
| 72 // However, it comes with the advantage of having a 1-file | |
| 73 // implementation of the generator. It should be fairly easy | |
| 74 // to change, should it become a problem later. | |
| 75 // | |
| 76 // Scheme for adding a new entry point: | |
| 77 // | |
| 78 // 1. determine if it's a platform-dependent or independent entry point | |
| 79 // a) if platform independent: make subsequent changes in the independent files | |
| 80 // b) if platform dependent: make subsequent changes in the dependent files | |
| 81 // 2. add a private instance variable holding the entry point address | |
| 82 // 3. add a public accessor function to the instance variable | |
| 83 // 4. implement the corresponding generator function in the platform-dependent | |
| 84 // stubGenerator_<arch>.cpp file and call the function in generate_all() of that file | |
