public class TracedStack
extends Stack
```
This Stack saves additional information with stack elements, to keep track of their origins.
The stack stores a given producer Value along with each Value it stores. It then generalizes a given collected Value with the producer Value of each Value it loads. The producer Value and the initial collected Value can be set. The generalized collected Value can be retrieved, either taking into account dup/swap instructions as proper instructions or ignoring them.
