This is missing the tracking code which should look like this (you may need to move the function definition to SandboxIR.cpp)
```
  auto &Tracker = getTracker();
  if (Tracker.isTracking())
    Tracker.track(Change: std::make_unique<SetVolatile>(cast<lnstruction>(this)), Tracker));
  cast<llvm::LoadInst>(Val)->setVolatile(V);
```
