 ## Development tools
 
-* [pydump](chore/_xtool/pydump): It's the first program compiled by `llgo` (NOT `go`) in a production environment. It outputs symbol information (functions, variables, and constants) from a Python library in JSON format, preparing for the generation of corresponding packages in `llgo`.
+* [pydump](_xtool/pydump): It's the first program compiled by `llgo` (NOT `go`) in a production environment. It outputs symbol information (functions, variables, and constants) from a Python library in JSON format, preparing for the generation of corresponding packages in `llgo`.
 * [pysigfetch](https://github.com/goplus/hdq/tree/main/chore/pysigfetch): It generates symbol information by extracting information from Python's documentation site. This tool is not part of the `llgo` project, but we depend on it.
-* [llpyg](chore/llpyg): It is used to automatically convert Python libraries into Go packages that `llgo` can import. It depends on `pydump` and `pysigfetch` to accomplish the task.
-* [llgen](chore/llgen): It is used to compile Go packages into LLVM IR files (*.ll).
-* [ssadump](chore/ssadump): It is a Go SSA builder and interpreter.
+* [llpyg](compiler/chore/llpyg): It is used to automatically convert Python libraries into Go packages that `llgo` can import. It depends on `pydump` and `pysigfetch` to accomplish the task.
+* [llgen](compiler/chore/llgen): It is used to compile Go packages into LLVM IR files (*.ll).

 How do I generate these tools?
