Oh come on, it's at the top of the page: "A lot of people frequently have questions about debugging GCC. In particular, how to debug the compiler itself, instead of the driver. Here is a quick rundown: Assuming you've produced preprocessed source (see the bug reporting directions for how to do this), and have a debuggable compiler built somewhere, you can simply do gdb --args <location of cc1, cc1plus, or whatever compiler for the language the preprocessed source file is in> <flags passed to compiler> This will enable you to debug the compiler itself, instead of the driver."
