I wholeheartly applaude this effort. At TAMU, we have been developing similar high level compiler-neutral data structures for program representations as part of a larger framework. An overview was presented recently at LCPC05

I deeply regret we did not have time to finish and make a first release in time for consideration -- the truth is, it really is a full time job working on C++, let alone developing supporting tool and other academic considerations.

I'm delighted to see GCC moving forward to more advanced internal infrastructure. We would most certainly give feedbacks based on our own experience so far.
