* vm_method.c (rb_unlink_method_entry, rb_sweep_method_entry):
added. Unlinked method entries are collected to vm->unlinked_method_entry_list. On the GC timing, mark all method entries which are on all living threads. Only non-marked method entries are collected. This hack prevents releasing living method entry. [Performance Consideration] Since this Method Entry GC (MEGC) doesn't occuer frequently, MEGC will not be a performance bottleneck. However, to traverse living method entries, every control frame push needs to clear cfp->me field. This will be a performance issue (because pushing control frame is occurred frequently). Bug #2777 [ruby-dev:40457] * cont.c (fiber_init): init cfp->me. * gc.c (garbage_collect): kick rb_sweep_method_entry(). * method.h (rb_method_entry_t): add a mark field. * vm.c (invoke_block_from_c): set passed me. * vm.c (rb_thread_mark): mark cfp->me. * vm_core.h (rb_thread_t): add a field passed_me. * vm_core.h (rb_vm_t): add a field unlinked_method_entry_list. * vm_insnhelper.c (vm_push_frame): clear cfp->me at all times. * vm_insnhelper.c (vm_call_bmethod): pass me. * bootstraptest/test_method.rb: add a test. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
