How does GCC4 transform GIMPLE IR to SSA?

Hi all:

I'm trying to understand GCC 4 as part of my research,especially the
SSA form in this compiler.I have read some literatures about SSA
form,and get the ouput in the form of SSA from GCC.

But for more details,I need to know the exact procedures how GIMPLE
form is transformed into SSA.Thus, I wonder that if someone could show
me the transformation flow or something related.

Thanks in advance.
