-//===- PrintSCC.cpp - Enumerate SCCs in some key graphs -------------------===//

-//
-// This file provides passes to print out SCCs in a CFG or a CallGraph.
-// Normally, you would not use these passes; instead, you would use the
-// scc_iterator directly to enumerate SCCs and process them in some way.  These
-// passes serve three purposes:
-//
-// (1) As a reference for how to use the scc_iterator.
-// (2) To print out the SCCs for a CFG or a CallGraph:
-//       analyze -cfgscc            to print the SCCs in each CFG of a module.
-//       analyze -cfgscc -stats     to print the #SCCs and the maximum SCC size.
-//       analyze -cfgscc -debug > /dev/null to watch the algorithm in action.
-//
-//     and similarly:
-//       analyze -callscc [-stats] [-debug] to print SCCs in the CallGraph
-//
-// (3) To test the scc_iterator.
