I think a function to tell whether an arbitrary graph node is part of a cycle could be useful in a variety of circumstances; is there another header file where it would be more appropriate? --Patrick

Hi, I've been using scc_iterator, and I added the templates necessary to make it work with inverse graphs. I also added a "bb_reachable" function to tell whether an arbitrary graph node is part of cycle. Might this be useful to others? (Sorry for the double post; previous patch didn't compile.) --Patrick --- include/llvm/ADT/SCCIterator.h (revision 76093) +++
