Correctly Compiling Proofs About Programs Without Proving Compilers Correct

Authors: Audrey Seo, Christopher Lam, Dan Grossman, and Talia Ringer

Published in: LIPIcs, Volume 309, 15th International Conference on Interactive Theorem Proving (ITP 2024)

Abstract
Guaranteeing correct compilation is nearly synonymous with compiler verification. However, the correctness guarantees for certified compilers and translation validation can be stronger than we need. While many compilers do have incorrect behavior, even when a compiler bug occurs it may not change the program’s behavior meaningfully with respect to its specification. Many real-world specifications are necessarily partial in that they do not completely specify all of a program’s behavior. While compiler verification and formal methods have had great success for safety-critical systems, there are magnitudes more code, such as math libraries, compiled with incorrect compilers, that would benefit from a guarantee of its partial specification. This paper explores a technique to get guarantees about compiled programs even in the presence of an unverified, or even incorrect, compiler. Our workflow compiles programs, specifications, and proof objects, from an embedded source language and logic to an embedded target language and logic. We implement two simple imperative languages, each with its own Hoare-style program logic, and a system for instantiating proof compilers out of compilers between these two languages that fulfill certain equational conditions in Coq. We instantiate our system on four compilers: one that is incomplete, two that are incorrect, and one that is correct but unverified. We use these instances to compile Hoare proofs for several programs, and we are able to leverage compiled proofs to assist in proofs of larger programs. Our proof compiler system is formally proven sound in Coq. We demonstrate how our approach enables strong target program guarantees even in the presence of incorrect compilation, opening up new options for which proof burdens one might shoulder instead of, or in addition to, compiler correctness.

08061 Abstracts Collection – Types, Logics and Semantics for State

Authors: Amal Ahmed, Nick Benton, Martin Hofmann, and Greg Morrisett

Published in: Dagstuhl Seminar Proceedings, Volume 8061, Types, Logics and Semantics for State (2008)

Abstract
From 3 February to 8 February 2008, the Dagstuhl Seminar 08061 ``Types, Logics and Semantics for State'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

A Unified Framework for Verification Techniques for Object Invariants

Authors: Sophia Drossopoulou, Adrian Francalanza, P. Müller, and Alexander J. Summers

Published in: Dagstuhl Seminar Proceedings, Volume 8061, Types, Logics and Semantics for State (2008)

Abstract
Object invariants define the consistency of objects. They have subtle semantics, mainly because of call-backs, multi-object invariants, and subclassing. Several verification techniques for object invariants have been proposed. It is difficult to compare these techniques, and to ascertain their soundness, because of their differences in restrictions on programs and invariants, in the use of advanced type systems (e.g., ownership types), in the meaning of invariants, and in proof obligations. We develop a unified framework for such techniques. We distil seven parameters that characterise a verification technique, and identify sufficient conditions on these parameters which guarantee soundness. We instantiate our framework with three verification techniques from the literature, and use it to assess soundness and compare expressiveness.
