not enabled.
Fix uglygep.ll to not be x86-specific.

When determining a canonical insert position, don't climb deeper2010-04-09T22:07:05ZDan Gohmangohman@apple.com2010-04-09T22:07:05Zurn:sha1:e5f76877aee6f33964de105893f0ef338661ecad

dominated by the loop latch of any loop in the post-inc set which
has a latch.

Generalize IVUsers to track arbitrary expressions rather than expressions2010-04-07T22:27:08ZDan Gohmangohman@apple.com2010-04-07T22:27:08Zurn:sha1:448db1cdef5872713ef77beffacf502ae3450cd7
explicitly split into stride-and-offset pairs. Also, add the
ability to track multiple post-increment loops on the same expression.
This refines the concept of "normalizing" SCEV expressions used for
to post-increment uses, and introduces a dedicated utility routine for
normalizing and denormalizing expressions.
This fixes the expansion of expressions which are post-increment users
of more than one loop at a time. More broadly, this takes LSR another
step closer to being able to reason about more than one loop at a time.

reflects this. This fixes PR6453.
