Hi!

Graph printing is actually done as part of the -analyze option, and by
default will print the globals graph as well as each function's graph.

If you're interested in only particular functions' graphs, use the
-dsa-only-print option (in addition to -analyze) to specify which
function(s) to limit printing to.  The globals graph is emitted at all
times regardless.

Hope this helps, and let me know if you have any further questions or issues :)
