<laugh> I was just teasing.

I am all for a good documentation of the GENERIC tree codes and their
semantics.  Right now it is not even clear which tree codes will
eventually make up GENERIC.  I discussed this shortly with Diego, a few
weeks ago.  I had started documenting GENERIC, but that is on hold a bit
now because it really isn't quite clear to me (or anybody, apparently)
what trees we really need to make GENERIC generic enough.

It is an interesting idea to define GENERIC as "an IR capable of
representing CIL + GNU C/C++ extensions" and build the IR from there.  I
think it is a bad idea to re-invent the wheel.

But in the end, no IR is OK for Fortran if it cannot represent array
assignments.  I had a dream... :-)

You pick a lot of hay on that fork of yours.  You should try to get
payed for hacking on GCC ;-)
(Or is all this a voluntary effort?  Maaaan, way cooool, duuude :-D )
