Hi GCC developers,

	I am learning GCC. But the GCC code is hard to understand.
	I'm reading the c compiler of GCC. It seems the understanding of AST/GENERIC representation is very important.

	Is there a tool can visualize the AST/GENERIC representation?

	Do you have some advice for GCC beginner? Is there some documentations can help in the learning of GCC?

Thanks,
Flint
