Predator: a tool for verification of low-level list manipulation. (Competition contribution) Predator is a tool for automated formal verification of sequential C programs operating with pointers and linked lists. The core algorithms of Predator were originally inspired by works on separation logic with higher-order list predicates, but they are now purely graph-based and significantly extended to support various forms of low-level memory manipulation used in system-level code. This paper briefly introduces Predator and describes its participation in the Software Verification Competition SV-COMP’13 held at TACAS’13.
