Detailed Description
A direct call site.
Used to represent call sites where the address of the callee is fixed (e.g. a function call in C in which the call target is not a function pointer).
Definition at line 336 of file Function.h.
Constructor & Destructor Documentation
◆ DirectCallEdge()
|
inline |
Construct a call edge using a symbol name to identify the callee, and a return PC within the calling function to identify a specific call site.
Definition at line 340 of file Function.h.
References lazy_callee, and symbol_name.
Member Function Documentation
◆ GetCallee()
|
overridevirtual |
Get the callee's definition.
Note that this might lazily invoke the DWARF parser. A register context from the caller's activation is needed to find indirect call targets.
Implements lldb_private::CallEdge.
