Very nice. I would strongly encourage you to create a sub-branch. The
patch is massive and it is very difficult to get an idea of what it does
by just staring at it.
tree-chrec.c could use a bit more documentation. Several functions have
no documentation at all. The routines seem mostly self-explanatory, but
still.
The high-level overview in tree-data-ref.c and tree-scalar-evolution.c
is helpful. Thanks. Any reason you chose Allen and Kennedy's book? I
haven't read it. Is it worth getting?
What's the idea behind tree-fold.[ch]? Are you trying to replace
fold-const.c or are these functions specific for data dependency?
They look like generic folders to me.

Yes, that's a good idea.
Diego.
