What exactly are a "basic" and "general" induction variables? I see a lot
of references to them on the list and in the code, but not in any
literature that I've found.

these guys are going to make short work of switching to GNU/Linux

Literature:
Principles of Compiler Design
Alfred V. Aho and Jeffrey D. Ullman
Addison - Wesley, 1977
Chapter 13 More about loop optimization.
Paragraph 13.5 Induction variable elimination.
[ it helps to consult a book old enough to forego the one-dimensionality
of C "arrays". ]
