Hi,
I have a question regarding how gcc optimize a program.

First, what are the objects when gcc do the optimiztion, RTL structures?
if true, which means gcc optimize closed with the target machines, 
right?                 

Second, is there anyway I can pull the data flow information from the 
gcc, which is a graph description of the program.  Long time ago,
someone told me that the start point to interface with gcc is tree.*.

But what I am interested is the optimized control and data flow graph,
is this possible?

thanks for your help.
