Ted Kremenek ebc5500e50 Previously GraphWriter assumed operator*() for node_iterator always ... returned a reference type. This patch allows operator*() to return a non-reference type while still maintaining the old behavior when it does return a reference type. This patch was motivated when I tried to use "df_iterator" (see llvm/ADT/DepthFirstIterator.h) as a "node_iterator", as df_iterator does not return a reference type and thus we would get a compilation error when trying to take the address of a temporary. llvm-svn: 42151		2007-09-19 21:26:49 +00:00
