programs with dynamic linked data structures, programs with pointers, low-level
pointer operations, static analysis, shape analysis, separation logic,
bi-abduction
The paper proposes a new static analysis designed to handle open programs, i.e.,
fragments of programs, with dynamic pointer-linked data structures in particular,
various kinds of lists that employ advanced low-level pointer operations. The
goal is to allow such programs be analysed without a need of writing analysis
harnesses that would first initialise the structures being handled. The approach
builds on a special flavour of separation logic and the approach of
bi-abduction. The code of interest is analyzed along the call tree, starting from
its leaves, with each function analysed just once without any call context,
leading to a set of contracts summarizing the behaviour of the analysed
functions. In order to handle the considered programs, methods of abduction
existing in the literature are significantly modified and extended in the paper.
The proposed approach has been implemented in a tool prototype and successfully
evaluated on not large but complex programs.
