| // 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. |
