Abstract

ESBMC implements many state-of-the-art techniques that combine abstract interpretation and model checking. Here, we report on new and improved features that allow us to obtain verification results for previously unsupported programs and properties. ESBMC now employs a new static interval analysis of expressions in programs to increase verification performance. This includes interval-based reasoning over booleans and integers, and forward-backward contractors. Other relevant improvements concern the verification of concurrent programs, as well as several operational models, internal ones, and also those of libraries such as pthread and the C mathematics library. An extended memory safety analysis now allows tracking of memory leaks that are considered still reachable.
