If it is free software, how about putting it directly into g++?

If it is not free software... I'm afraid you are looking at the wrong
compiler.

Really you're talking about the compiler IR.  There's some
documentation, e.g., c-tree.texi.  This stuff isn't really kept in one
place, it is spread out all over; which makes sense since this is the
major thing that a front end computes.

Search through the archives, I think there are several threads about
this.  IIRC in the past there were some political difficulties in this
area; but these days perhaps (I hope) the situation may be changing.
It is hard to know.

Perhaps I'm misunderstanding you... any C-like language is going to
have multiple scopes whose natural representation is a tree.  For C++
the situation is going to be even more complicated.
