Ted Kremenek f357afb404 Modified node creation of ImutAVLTree to do a hash lookup for an existing ... node in the FoldingSet of nodes held by the Factory object. If we we find a node with a matching hash, we do a full structural comparison. Nodes are also now inserted into the FoldingSet only when we mark them Immutable, as their children can change during intermediate-rebalancing. The 'Profile' method for ImutAVLTree is no longer used when looking up existing ImutAVLTrees with a given set of contents; instead the Profile method is used by other clients that wish to insert such a tree into a folding set. This means that we are not using FoldingSet in ImutAVLTreeFactory in the way it was intended, but instead are using it as an opaque hashtable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46717 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-04 21:15:24 +00:00
