Lingva: generating and proving program properties using symbol elimination. We describe the Lingva tool for generating and proving complex program properties using the recently introduced symbol elimination method. We present implementation details and report on a large number of experiments using academic benchmarks and open-source software programs. Our experiments show that Lingva can automatically generate quantified invariants, possibly with alternation of quantifiers, over integers and arrays. Moreover, Lingva can be used to prove program properties expressing the intended behavior of programs.
