10 // a RecursiveASTVisitor to look at each declaration and populate the info
11 // into the internal representation. Each seen declaration is serialized to
12 // to bitcode and written out to the ExecutionContext as a KV pair where the
13 // key is the declaration's USR and the value is the serialized bitcode.
