I think that I can help since I am having the same problem :) The best references that I can give you is the GCC Frontend HOWTO at http://www.tldp.org/HOWTO/GCC-Frontend-HOWTO.html. It is based on a old gcc, but most of the tree structure still applies. Two colleges and I are working on a minimal "hello world" front end for gcc. You can find a alpha version at http://ltc08.ic.unicamp.br/svn/scheme/branches/hello-world I also recommend that you take a look at treelang. It is quite simpler than the others frontends in gcc. I hope this helps, Rafael Ávila de Espíndola
