I started Pascal backend for a while now. Have a look at: http://sparcs.kaist.ac.kr/~tinuviel/pypy/

Resulting Pascal source can be compiled with FPC(Free Pascal Compiler), available from http://www.freepascal.org/

What do you think? Also, if I understood correctly, translation part is undergoing much change in the branch. What do I need to change?

There is not too much to change. Mostly, back-ends must now work directly with graphs instead of manipulating Python function objects. I take it that you know that the current approach for back-ends is to use the output of the RTyper, not just the annotations? It's particularly useful for a back-end like Pascal. You would get flow graphs that contain "low-level" operations. For integer manipulation it is not such a big difference, but for any more complicated kind of objects it is essential because it allows you to care only about the "lltypes", i.e. structures (Pascal records), arrays and pointers.
