Summary: Separation logic is an extension of Hoare’s logic for reasoning about programs that manipulate pointers. It is based on the separating conjunction \(P \ast Q\), which asserts that \(P\) and \(Q\) hold for separate portions of computer memory.
This tutorial on separation logic has three parts.
1. Basics: Concentrating on highlights from the early work.
2. Model Theory: The model theory of separation logic evolved from the general resource models of bunched logic and includes an account of program dynamics in terms of their interaction with resource.
3. Proof Theory: I describe the aspects of proof theory, in particular new entailment questions (frame and anti-frame inference), which are important for applications in mechanized program verification.
