- // 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.
