Is there a way that I can dump the output of viewGraph() in a file and run dot over it offline and then copy the final pictures to my windows machine to have some idea about the SelectionDAG.<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal>Also, can someone please point me to a location in source code where selectionDAG is traversed.
