Abstract
We also present an incremental checking framework, called iChecker, that leverages iWatcher to provide an iChecker library for efficient, incremental, run-time consistency checks of mutable data structures in C programs. The basic idea of iChecker is to perform a consistency check with a local check (on the parts that need to be checked due to the modifications since the last consistency check) instead of with a global check. The evaluation using four case studies shows that iChecker reduces the checking overhead by 1.1-155 times (23.3 on average) over global checks for large data structures. The required code modifications for iChecker are 25-108 lines (including the global checkers), which are 10-56 lines more than the modifications for traditional global checks.
