编译器是如何编译代码的？

我已经安装了MPLAX V.3.60并编译了现有的项目。当编程PIC时，我看到了一个新的消息，我以前从未在以前的MPLAX版本中看到过。我在以前版本的MPLAB X中使用了这个项目：消息摘要：程序空间使用7FF8H字节（34.5%）的2C18H（11288）的数据空间，使用了1H 2H（498）的400字节（48.6%）配置位，使用3H（3）的3H字（100%）数据堆栈空间，使用了0H（0）的200字节（0%）BUI。LD成功（总时间：5s）加载代码从D:/xToNoDaIKiN/xSt/Dist/Deult/NuthOnalac x.Engult.HEX…警告：D:/MPLABXPix/InStEndoAKIN／NUSTONALACI.X/Dista/DeFult/Studio/NuthOnalCal.x.Engultudi.HEX包含位于地址T的代码。帽子不存在于PIC18F25J10上。代码不完全加载。加载完成连接到程序员…编程目标…编程完成DRunungTarget……我怀疑它是否是MPLAB X的一个新特性，它检测到这个问题，还是一个bug？如果HEX文件的代码位于PIC中不存在的地址，为什么只有警告？编译器是如何编译代码的？编译器是XC8 V.1.41。这个项目似乎运作良好。



      以下为原文

    I have installed MPLAB X v.3.60 and compiled existing project.
When programming the PIC I saw a new message, then I never saw in previous MPLAB X versions before. I used this project in the previous versions of MPLAB X.
The message is:

Memory Summary:
    Program space used 2C18h ( 11288) of 7FF8h bytes ( 34.5%)
    Data space used 1F2h ( 498) of 400h bytes ( 48.6%)
    Configuration bits used 3h ( 3) of 3h words (100.0%)
    Data stack space used 0h ( 0) of 200h bytes ( 0.0%)

I wonder whether it is a new feature of MPLAB X that detected this problem, or is it a bug? If the hex file has the code located at addresses that do not exist in the PIC, why is it only a warning? How did compiler compiled the code? The compiler is XC8 v.1.41. The program seems to be working fine.
