Dan Gohman f27e33baa7 Optimize DAGCombiner's worklist processing. Previously it started ... its work by putting all nodes in the worklist, requiring a big dynamic allocation. Now, DAGCombiner just iterates over the AllNodes list and maintains a worklist for nodes that are newly created or need to be revisited. This allows the worklist to stay small in most cases, so it can be a SmallVector. This has the side effect of making DAGCombine not miss a folding opportunity in alloca-align-rounding.ll. llvm-svn: 55498		2008-08-28 21:01:56 +00:00
