Tree stability going into Version 3.0

[N. D. Culver]

I have a language front end which uses a private tree structure. The front
end currently regenerates C source and calls GCC to generate machine code.
Recently, I've been thinking about writing a 'private tree' to 'gcc tree' program
which incorporates the GCC back end. The new program would be GPLed.

Can I depend upon the Web documentation for the 'gcc tree' internals going
forward for the next couple of years?

Thanks,
Norman Culver
