D15134: decrease StateData space by more than 50% and half the number of needed mallocs

[Christoph Cullmann]

cullmann added a comment.


  Proposed solution that is "safe": We use a weak reference to check for state validity.
  This is bit more expensive than the raw-pointer but even save if e.g. by accident a new definition gets allocated to the same address as an old one.
  I added shortcut to check for pointer equality for shared states.
