 	* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):
-	  add a new otpimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
+	  add a new optimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
 	  This optimization makes all cfunc method calls `frameless', which
-	  is fster than ordinal cfunc method call.
+	  is faster than ordinal cfunc method call.
 	  If `frame' is needed (for example, it calls another method with
 	  `rb_funcall()'), then build a frame. 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.
+	    (2) Check the delayed frame building 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

 	  This optimization only works for cfunc methods which do not need
 	  their `frame'.
 	  After evaluation on my environment, this optimization does not
