Unbounded Lazy-CSeq: a lazy sequentialization tool for C programs with unbounded context switches (competition contribution)
At 21st International Conference on Tools and Algorithms for the Construction and Analysis of Systems (TACAS), United Kingdom.
11 - 18 Apr 2015.
We describe a new CSeq module for the verification of multi-threaded C programs with dynamic thread creation. This module implements a variation of the lazy sequentialization algorithm implemented in Lazy-CSeq. The main novelty is that we now support an unbounded number of context switches and allow unbounded loops, while the number of allowed threads still remains bounded. This is achieved by a modified sequentialization transformation and the use of the CPAChecker as sequential verification backend.
