if (m_stop_info_stop_id != process_stop_id) {
       }
     }
 
     // The stop info can be manually set by calling Thread::SetStopInfo() prior
     // to this function ever getting called, so we can't rely on
     // "m_stop_info_stop_id != process_stop_id" as the condition for the if
     // statement below, we must also check the stop info to see if we need to
     // override it. See the header documentation in
-    // Process::GetStopInfoOverrideCallback() for more information on the stop
+    // Architecture::OverrideStopInfo() for more information on the stop
     // info override callback.

       m_stop_info_override_stop_id = process_stop_id;

         if (const Architecture *arch =
                 process_sp->GetTarget().GetArchitecturePlugin())
           arch->OverrideStopInfo(*this);
