Technical parameters
Symbiotic 8 je pokročilý nástroj pro analýzu a verifikaci programů napsaných v jazyce C. Nástroj kombinuje různé statické analýzy, instrumentaci, prořezávání a symbolickou exekuci. Symbiotic 8 dokáže využívá i další nástroje pro analýzu kódu, zejména Predator pro statickou analýzu zaměřenou na práci s pamětí, knihovnu DG pro pointer analýzu a prořezávání programu a symbolické exekutory Klee a Slowbeast.

Abstract
V originále
Symbiotic 8 extends the traditional combination of static analyses, instrumentation, program slicing, and symbolic execution with one substantial novelty, namely a technique mixing symbolic execution with k-induction. This technique can prove the correctness of programs with possibly unbounded loops, which cannot be done by classic symbolic execution. Symbiotic 8 delivers also several other improvements. In particular, we have modified our fork of the symbolic executor Klee to support the comparison of symbolic pointers. Further, we have tuned the shape analysis tool Predator to perform better on llvm bitcode. We have also developed a light-weight analysis of relations between variables that can prove the absence of out-of-bound accesses to arrays.
