Verified heap theorem prover by paramodulation

Abstract

We present VeriStar, a verified theorem prover for a decidable subset of separation logic. Together with VeriSmall [3], a proved-sound Smallfoot-style program analysis for C minor, VeriStar demonstrates that fully machine-checked static analyses equipped with efficient theorem provers are now within the reach of formal methods. As a pair, VeriStar and VeriSmall represent the first application of the Verified Software Toolchain [4], a tightly integrated collection of machine-verified program logics and compilers giving foundational correctness guarantees.
