Subjective Concurrent Separation Logic
From Owicki-Gries’ resource invariants and Jones’ rely/guarantee to modern variants based on separation logic, axiomatic program logics for concurrency have a limited form of compositionality. Proving non-trivial properties usually requires the use of auxiliary state, which is “objective” in the sense that each thread’s auxiliary state is given a globally-unique name. Since auxiliary state expo...
متن کاملCertificates and Separation Logic
Modular and local reasoning about object-oriented programs has been widely studied for programing languages such as C# and Java. Once source programs have been proven, the next verification challenge is to ensure that the code produced by the compiler is correct. Since verifying a compiler can be extremely complex, this paper uses proof-transforming compilation, an alternative approach which au...
متن کاملFictional Separation Logic
Separation logic formalizes the idea of local reasoning for heap-manipulating programs via the frame rule and the separating conjunction P ∗ Q, which describes states that can be split into separate parts, with one satisfying P and the other satisfying Q. In standard separation logic, separation means physical separation. In this paper, we introduce fictional separation logic, which includes mo...
متن کاملSeparation Logic Modulo Theories
Logical reasoning about program behaviours often requires dealing with heap structures as well as scalar data types. Advances in Satisfiability Modulo Theories (SMT) offer efficient procedures for dealing with scalar values, yet they lack expressive support for dealing with heap structures. In this paper, we present an approach that integrates separation logic—a prominent logic for reasoning ab...
متن کاملQuantitative Separation Logic
We present quantitative separation logic (QSL). In contrast to classical separation logic, QSL employs quantities which evaluate to real numbers instead of predicates which evaluate to boolean values. The connectives of classical separation logic, separating conjunction (⋆) and separating implication (−−⋆ ), are both lifted from predicates to quantities. This extension is conservative: Both con...
