Not really.  GENERIC trees are generated by removing most/all language
dependent features from the original parse trees.  To get the original
parse trees, you have to look before the genericize pass.

You'll find a brief intro to GENERIC and GIMPLE in

Jason will present a much more detailed description next month at the
GCC summit.
