In this paper, we present the first automated technique for differentially testing soundness and precision of program analyzers. ... Our technique detected soundness and precision issues in most analyzers, and we evaluated the implications of these issues to both designers and users of program analyzers. ... ACKNOWLEDGMENTS We are very grateful to the program-analysis designers that we contacted, Matthias Dangl, Arie Gurfinkel, Jorge Navas, and Zvonimir Rakamaric, for their prompt replies and fixes as well ...arXiv:1812.05033v2 fatcat:ygujkf4a3ba7jojh2d57gmmd7m

Static analyzers should be correct. We used the random Cprogram generator Csmith, initially intended to test C compilers, to test parts of the Frama-C static analysis platform. ... Several bugs were also found in Csmith, even though it had been extensively tested and had been used to find numerous bugs in compilers. ... The originality of our experiment is that differential testing does not apply directly to static analyzers. ...doi:10.1007/978-3-642-28891-3_12 fatcat:56wsztwsbnejdp26tm4olshw7a

We show that abstract interpretation-based static program analysis can be made efficient and precise enough to formally verify a class of properties for a family of large programs with few or no false ... This is achieved by refinement of a general purpose static analyzer and later adaptation to particular programs of the family by the end-user through parametrization. ... Then the loop invariant inter-val is computed iteratively with F F,F , which is simply less precise than with F F,F , but sound. The loop stabilization test is performed with F F,F which is sound. ...doi:10.1145/781131.781153 dblp:conf/pldi/BlanchetCCFMMMR03 fatcat:dyxxvk6urbfavmbg73pinpqxba
