How can rustc_plugin be used to analyze the code of rustc?

[cicilzx]

Hi, thank you for open-sourcing rustc_plugin, it has been very helpful for my research.

However, I want to analyze the source code of rustc or the std library, and in this case, I cannot use cargo build for compilation, so I can't directly use commands like cargo tool. Do you have any good suggestions? Thank you so much!

rustc_plugin should be able to run on individual crates in the Rust compiler. I've used Flowistry to analyze rustc source code before. What specific issue are you running into?
