        <div>
        <pre>extern int x;
  void f1(int i) {
    i = x;
  }

This has no location for 'i' (the store from 'x' was dead, so it was removed).
It'd be nice to have a location for 'i' on entry to the function, even if it's
immediately clobbered once the first instruction of the function is executed.</pre>
