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