+// This file defines the generic ProfileInfo interface, which is used as the
+// common interface used by all clients of profiling information, and
+// implemented either by making static guestimations, or by actually reading in
+// profiling information gathered by running the program.
+//
+// Note that to be useful, all profile-based optimizations should preserve
+// ProfileInfo, which requires that they notify it when changes to the CFG are
+// made.
