In other words, this + optimization delays frame building. + However, to delay the frame building, we need additional overheads: + (1) Store the last call information. + (2) Check the delayed frame buidling before the frame is needed. + (3) Overhead to build a delayed frame. + rb_thread_t::passed_ci is storage of delayed cfunc call information. + (1) is lightweight because it is only 1 assignment to `passed_ci'. + To achieve (2), we modify GET_THREAD() to check `passed_ci' every + time. It causes 10% overhead on my envrionment. + This optimization only works for cfunc methods which do not need + their `frame'. + After evaluation on my environment, this optimization does not + effective every time. Because of this evaluation results, this + optimization is disabled at default. + + * vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour + of VM internals. I will extend this feature. + + * vm_method.c, method.h: change parameters of the `invoker' function. + Receive `func' pointer as the first parameter. + Tue Oct 23 06:21:05 2012 Aaron Patterson <aaron@tenderlovemaking.com> * ext/psych/parser.c: just get the constant defined in Ruby. @@ -49,7 +49,7 @@ struct rb_call_info_struct;
