I don't know the current codebase at all (unfortunately). I think it
is useful to get yourself familiarized
with it even if you start from scratch as it will get you to learn
something about GIMPLE and about
writing a frontend.
Note that LTO support already is able to output everything needed to
re-create GIMPLE thus from
there you can also learn what is required to populate a GIMPLE
representation. And LTO support
might be used to create output that can be read by the GIMPLE frontend
- the whole project
feels like finding a textual form of the LTO bytecode (in some way).
Note that it's always useful to ask such questions on the mailing list
as there may be other people
who can give useful input. Thus, CCed.
