llvm::CallGraphNode

Name

Description

CallRecord

A pair of the calling instruction (a call or invoke) and the call graph node being called. Call graph node may have two types of call records which represent an edge in the call graph ‐ reference or a call edge. Reference edges are not associated with any call instruction and are created with the first field set to None, while real call edges have instruction address in this field. Therefore, all real call edges are expected to have a value in the first field and it is not supposed to be nullptr. Reference edges, for example, are used for connecting broker function caller to the callback function for callback call sites.
