7127706: G1: re-enable survivors during the initial-mark pause
Summary: Re-enable survivors during the initial-mark pause. Afterwards, the concurrent marking threads have to scan them and mark everything reachable from them. The next GC will have to wait for the survivors to be scanned.

51 // compiled code and the run-time system. Platform-specific entry | |
52 // points are defined in the platform-specific inner class. | |

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