Automata-based Verification of Programs with Tree Updates

Popis výsledku v původním jazyce

This paper, which is an extended version of a paper originally published at TACAS'06, describes an effective verification procedure for imperative programs that handle (balanced) tree-like data structures. Since the verification problem considered is undecidable, we appeal to a classical semi-algorithmic approach in which the user has to provide manually the loop invariants in order to check the validity of Hoare triples of the form {P}C{Q}, where P, Q are the sets of states corresponding to the pre- and post-conditions, and C is the program to be verified. We specify the sets of states (representing tree-like memory configurations) using&nbsp; a special class of tree automata named Tree Automata with Size Constraints (TASC). The main advantage of using TASC in program specifications is that they recognize non-regular sets of tree languages such as the <i>AVL trees</i>, the&nbsp; <i>red-black trees</i>, and in general, specifications involving arithmetic reasoning about the lengths (de
