+ * vm_insnhelper.h (CI_SET_FASTPATH): add new parameter `enabled'.
+ If `enable' is 0 then CI_SET_FASTPATH() doesn't work.
+ And add new configuration option OPT_CALL_FASTPATH. If this macro
+ was defined by 0, then CI_SET_FASTPATH() doesn't work any more.
+
+ * vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter
+ of CI_SET_FASTPATH if this method is protected.
