Reconciling -save-temps intermediate file with cfg

[0xd@tutamail.com]

I am attempting to reconcile the preprocessed C file with the cfg produced from -fdump-tree-cfg-blocks-lineno. The resulting cfg identifies the line numbers of basic blocks as they relate to the original source file, however I am trying to correlate the bb's to the intermediate file (which is what I'm ultimately parsing). Is there a way to do this?

Thank you in advance for any help.
