怎样剥离一个解释器的执行部分？

想在资源受限的嵌入式设备上，只保留解释器的执行部分，把其他部分分离出去。
怎么样分析一个解释器，把它的执行部分整理出来？？

回复内容：

• jswrap开头的都是用于实现JavaScript标准库的，这些如果有用不到的可以删掉；
  
• 然后剩下的js开头的文件（例如jsdevice.[h|c]）主要都是跟操作嵌入式设备相关的，这些也可以看题主的需求裁剪。

As a Linux user Gordon was aware that whatever tools were used had to work reliably on multiple platforms without needing extra software, so building an interpreter into the microcontroller seemed the obvious way forwards. BASIC interpreters for microcontrollers have been around for a while (like the amazing Maximite), but until recently the amount of built-in RAM and Flash in microcontrollers has been a stumbling block for more complex languages. When Gordon saw the STM32F1 development boards with 128kb of Flash and 8kb of RAM he realised he could use the lessons learned from his TinyJS JavaScript interpreter (originally built for Morphyre) to produce something that would run within those limits - and so Espruino started!
