Python is an increasingly popular dynamic programming language, particularly used in the
scientific community and well-known for its powerful and permissive high-level syntax. Our …

We discuss the design of Mopsa, an ongoing effort to design a novel semantic static
analyzer by abstract interpretation. Mopsa strives to achieve a high degree of modularity and …

Once deployed in blockchain, smart contracts become immutable: attackers can exploit bugs
and vulnerabilities in their code, that cannot be replaced with a bug-free version. For this …

We present a static analysis of endian portability for C programs. Our analysis can infer that
a given program, or two syntactically close versions thereof, compute the same outputs …

Smart contracts are immutable code deployed in a blockchain, whose execution modifies its
global state. Code im-mutability leads to immutable bugs. To prevent such bugs, static …

This paper introduces Tezla, an intermediate representation of Michelson smart contracts
that eases the design of static smart contract analysers. This intermediate representation …

To put sound program analysis at the fingertips of the software developer, we propose a
framework for interactive abstract interpretation of multithreaded C code. Abstract …

We present an abstract domain able to infer invariants on programs manipulating trees.
Trees considered in the article are defined over a finite alphabet and can contain …

To put static program analysis at the fingertips of the software developer, we propose a
framework for interactive abstract interpretation. While providing sound analysis results …

Ensuring the scalability of static analyzers defined by abstract interpretation poses
difficulties. A classical technique known to speed up analyses is the discovery and reuse of …
