This tutorial provides a programmer's introduction to the Satisfiability Modulo Theories
Solver Z3. It describes how to use Z3 through scripts, provided in the Python scripting …

This paper presents Siro, a new program transformation framework that translates between
different versions of Intermediate Representations (IR), aiming to better address the issue of …

Smart contracts are programs deployed on a blockchain. They are executed for a monetary
fee paid in gas—a clear optimization target for smart contract compilers. Because smart …

Python is an interpreted programming language that has been widely used in many fields.
The successful execution of a Python program depends on both the correctness of Python …

We propose a new static software analysis principle called Abstract Execution, generalizing
Symbolic Execution: While the latter analyzes all possible execution paths of a specific …

Abstract is a workbench for modeling statement-level transformation rules on programs with
the aim to formally verify their correctness. It is based on Abstract Execution, a verification …

We propose an abstract completion procedure for logically constrained term rewrite systems
(LCTRSs). This procedure can be instantiated to both standard Knuth-Bendix completion …

Abstract programs contain schematic placeholders representing potentially infinitely many
concrete programs. They naturally occur in multiple areas of computer science concerned …

Just-in-time (JIT) compilers make JavaScript run efficiently by replacing slow JavaScript
interpreter code with fast machine code. However, this efficiency comes at a cost: bugs in JIT …

The efficiency and the security of smart contracts are their two fundamental properties, but
might come at odds: the use of optimizers to enhance efficiency may introduce bugs and …
