Bounded Model Checking is one the most successful techniques for finding bugs in program. However, for programs with loops iterating over largesized arrays, bounded model checkers often exceed the limit of resources available to them. We present a transformation that enables bounded model checkers to verify a certain class of array properties. Our technique transforms an array-manipulating program in ANSI-C to an array-free and loop-free program. The transformed program can efficiently be verified by an off-the-shelf bounded model checker. Though the transformed program is, in general, an abstraction of the original program, we formally characterize the properties for which the transformation is precise. We demonstrate the applicability and usefulness of our technique on both industry code as well as academic benchmarks.
In REF , a technique to scale bounded model-checking by transforming a program with arrays and possibly unbounded loops to an array-free and loop-free program is presented.
