Dan Gohman efb9fbfdab When forgetting SCEVs for loop PHIs, don't forget SCEVUnknown values. ... These values aren't analyzable, so they don't care if more information about the loop trip count can be had. Also, SCEVUnknown is used for a PHI while the PHI itself is being analyzed, so it needs to be left in the Scalars map. This fixes a variety of subtle issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71533 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-12 01:27:58 +00:00

Transforms	Teach LSR to optimize more loop exit compares, i.e. change them to use postinc iv value. Previously LSR would only optimize those which are in the loop latch block. However, if LSR can prove it is safe (and profitable), it's now possible to change those not in the latch blocks to use postinc values.	2009-05-11 22:33:01 +00:00
