+// This file implements a transformation that attaches !callees metadata to
+// indirect call sites. For a given call site, the metadata, if present,
+// indicates the set of functions the call site could possibly target at
+// run-time. This metadata is added to indirect call sites when the set of
+// possible targets can be determined by analysis and is known to be small. The
+// analysis driving the transformation is similar to constant propagation and
+// makes uses of the generic sparse propagation solver.
