This method is similar to VM_METHOD_TYPE_CFUNC methods, but called cfunc without building new frame (does not push new control frame). If error is occured in cfunc, the backtrace only shows caller frame and upper. This kind of methods can be added by rb_define_method_fast(). This feature is similar to specialized instructions (opt_plus, etc), but more flexible (but a bit slower). * class.c (rb_define_method_fast): added. Maybe it will be renamed soon. * vm_insnhelper.c (vm_call_method): support method type VM_METHOD_TYPE_CFUNC_FAST. * proc.c (rb_method_entry_arity): catch up new method type. * vm_method.c (rb_add_method_cfunc_fast): added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37198 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
