Abstract: Separation logic is a popular specification language for imperative programs where the heap can only be mentioned through points-to assertions. However, separation logic's take on assertions does not match well with the classical view of assertions as boolean, side effect-free, potentially heap-dependent expressions from the host programming language familiar to many developers.

In this paper, we propose a variant of separation logic where side effect-free expressions from the host programming language, such as pointer dereferences and invocations of pure methods, can be used in assertions. We modify the symbolic execution-based verification algorithm used in Smallfoot to support mechanized checking of our variant of separation logic. We have implemented this algorithm in a tool and used the tool to verify some interesting programming patterns.
