Chris Lattner a5682853b9 Revamp the "CSEMap" datastructure used in the SelectionDAG class. This ... eliminates a bunch of std::map's in the SelectionDAG, replacing them with a home-grown hashtable. This is still a work in progress: not all the maps have been moved over and the hashtable never resizes. That said, this still speeds up llc 20% on kimwitu++ with -fast -regalloc=local using a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29550 91177308-0d34-0410-b5e6-96231b3b80d8		2006-08-07 23:03:03 +00:00
