Adam Nemet b4690e3fd1 [SelectionDAG] Force cycle detection in AssignTopologicalOrder before aborting ... DAG cycle detection is only enabled with ENABLE_EXPENSIVE_CHECKS. However we can run it just before we would crash in order to provide more informative diagnostics. Now in addition to the "Overran sorted position" message we also get the Node printed if a cycle was detected. Tested by building several configs: Debug+Assert, Debug+Assert+Check (this is ENABLE_EXPENSIVE_CHECKS), Release+Assert and Release. Also tried that the AssignTopologicalOrder assert produces the expected results. llvm-svn: 209977		2014-05-31 16:23:20 +00:00
