Have a look at the tree-ssa branch: the file you look for is gcc/tree-cfg.c
For more information on this branch and how to get it see

my dear friend:
   I am very appreciated for you help.
   Before I download the tree-ssa branch,I want to know another thing 
clearly.For program slicing,the control flow graph is based on the original 
statement, while not the modified statement.What's the concrete format of 
control flow graph in the tree-ssa branch ? Another thing is that can you 
mail me the file gcc/tree-cfg.c ? Because for me ,the whole tree-ssa branch 
is too huge, and our network charge is based on network flux.And for me the 
expected format of cfg is shown in the accessory .
