As in a graph colouring register allocator, I take it.
gcc doesn't use a graph colouring register allocator.

But gcc does build an interference graph. In gcc 4.3 the code is in
ra-conflict.c.
But gcc's code is full of details, and is not a good general example.
You would do much better to look at a textbook.
