Sorry for following up on this old e-mail but it just occured to me that the (unfinished) GIMPLE frontend would be a great place to bootstrap the new and shiny GIMPLE data structures. Of course for it to work you need to translate that back to fat-and-old GIMPLE and eventually finish the textual format dumping as well - not sure what the state of the gimple frontend branch is.
