Platform-specific entry // points are defined in the platform-specific inner class. // // Class scheme: // // platform-independent platform-dependent // // stubRoutines.hpp <-- included -- stubRoutines_<arch>.hpp // ^ ^ // | | // implements implements // | | // | | // stubRoutines.cpp stubRoutines_<arch>.cpp // stubRoutines_<os_family>.cpp stubGenerator_<arch>.cpp // stubRoutines_<os_arch>.cpp // // Note 1: The important thing is a clean decoupling between stub // entry points (interfacing to the whole vm; i.e., 1-to-n // relationship) and stub generators (interfacing only to // the entry points implementation; i.e., 1-to-1 relationship). // This significantly simplifies changes in the generator // structure since the rest of the vm is not affected. // // Note 2: stubGenerator_<arch>.cpp contains a minimal portion of // machine-independent code; namely the generator calls of // the generator functions that are used platform-independently. // However, it comes with the advantage of having a 1-file // implementation of the generator. It should be fairly easy // to change, should it become a problem later. // // Scheme for adding a new entry point: // // 1. determine if it's a platform-dependent or independent entry point // a) if platform independent: make subsequent changes in the independent files // b) if platform dependent: make subsequent changes in the dependent files // 2. add a private instance variable holding the entry point address // 3. add a public accessor function to the instance variable // 4. implement the corresponding generator function in the platform-dependent // stubGenerator_<arch>.cpp file and call the function in generate_all() of that file class StubRoutines: AllStatic { public: enum platform_independent_constants { max_size_of_parameters = 256 // max. parameter size supported by megamorphic lookups };
