| * the same as the locals in the previous frame, except that additional |
| * locals are defined (<code>nLocal</code> is 1, 2 or 3 and |

| * <li>{@link Opcodes#F_CHOP} representing frame with current locals are the |
| * same as the locals in the previous frame, except that the last 1-3 locals |
| * are absent and with the empty stack (<code>nLocals</code> is 1, 2 or 3).</li> |
