2001-06-25 03:54:32 +00:00
Chris Lattner 3fe4504c28 Big changes. Interval*.h is now more or less finalized. IntervalPartition
is recoded to use IntervalIterators.  IntervalIterators can now maintain
their own memory or let an external entity do it.

Loop depth is a new user of IntervalPartition for calculating the loop
nesting depth of a basic block

TODO: add IntervalPartition capability to split intervals between the looping
portion and the "tail" portion.
