// 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.
