Dan Gohman fef8bb24de Instead of eagerly creating new SCEVs to replace all SCEVs that are ... affected after a PHI node has been analyzed, just remove affected SCEVs from the Scalars map, so that they'll be (lazily) recreated as needed. This avoids creating SCEV objects that aren't actually needed. Also, rewrite the associated def-use walking code to be non-recursive and to continue traversing past Instructions that don't have an entry in the Scalars map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77032 91177308-0d34-0410-b5e6-96231b3b80d8		2009-07-25 01:13:03 +00:00
