Charge! - A Framework for Higher-Order Separation Logic in Coq

We present a comprehensive set of tactics for working with a shallow embedding of a higher-order separation logic for a subset of Java in Coq. The tactics make it possible to reason at a level of abstraction similar to pen-and-paper separation-logic proof outlines. In particular, the tactics allow the user to reason in the embedded logic rather than in the concrete model, where the stacks and heaps are exposed. The development is generic in the choice of heap model, and most of the development is also independent of the choice of programming language.
