Parameters
[in]CheckDWOIf this is false then only search for address matches in the current context's DIEs. If this is true, then each DWARFUnit that has a DWO file will have the debug info in the DWO file searched as well. This allows for lookups to succeed by searching the split DWARF debug info when using the main executable's debug info.
