Lang Hames 9e52663aa4 Add functions 'hasPredecessor' and 'hasPredecessorHelper' to SDNode. The ... hasPredecessorHelper function allows predecessors to be cached to speed up repeated invocations. This fixes PR10186. X.isPredecessorOf(Y) now just calls Y.hasPredecessor(X) Y.hasPredecessor(X) calls Y.hasPredecessorHelper(X, Visited, Worklist) with empty Visited and Worklist sets (i.e. no caching over invocations). Y.hasPredecessorHelper(X, Visited, Worklist) caches search state in Visited and Worklist to speed up repeated calls. The Visited set is searched for X before going to the worklist to further search the DAG if necessary. llvm-svn: 134592		2011-07-07 04:31:51 +00:00
