How to uninstall this compiler?

[YigaoFan]

Hello! I have installed this compiler on macOS 10.14.1. But after this installation, I found I made a wrong installation. It doesn't work on 64-bit platform normally. Then I used Docker to do the book's work. It works well. So I want to know how to uninstall this software(on macOS or other platforms) safely. Then I checked the Readme file, it doesn't contain this content. So I setup this issue. Maybe other people also want to know this in some situations.

Thanks for reading and answer!
