我想解析 lld 映射文件。有解释或文档吗？我检查了clang 文档和lld 文档，但没有找到有用的信息。这是我的地图文件的示例

这个源文件的标题有一个模糊的格式轮廓，它是我最好的：

https://github.com/llvm/llvm-project/blob/main/lld/COFF/MapFile.cpp

它描述的格式与link.exe 相同。其中一些描述如下：

https://www.codeproject.com/Articles/3472/Finding-Crash-Information-Using-the-MAP-File

我希望我能提供更多帮助，因为我还需要更多信息。
