In this paper, we report on a follow-up case study that explores the methodology from the perspective of three research questions: (a) can proof artefacts be used across verification tools; (b) are there bugs in verified code; and (c) can specifications be improved. To study these questions, we port the verification tasks for aws-c-common library to SeaHorn, SMACK and KLEE. We show the benefits of using compiler semantics and cross-checking specifications with different verification techniques, and call for standardizing proof library extensions to increase specification reuse. The verification tasks discussed are publicly available online. 收起
