摘要： A computer implemented program analysis method employing a set of new abstract domains applicable to non-convex invarients. The method analyzes programs statically using abstract interpretation while advantageously considering non-convex structures and in particular those situations in which an internal region of an unreachable state exists within a larger region of reachable states. The method employs a new set of non-convex domains (donut domains) based upon the notion of an outer convex region of reachable states (Domain D1) and an inner region of unreachable states (Domain D2) which advantageously permits capture of non-convex properties by using convex regions and operations.

摘要： Systems and methods are disclosed for performing error diagnosis of software errors in a program by from one or more error traces, building a repair program containing one or more modified program semantics corresponding to fixes to observed errors; encoding the repair program with constraints, biases and priortization into a constraint weighted problem; and solving the constraint weighted problem to generate one or more repair solutions, wherein the encoding includes at least one of: a) constraining one or more repairs choices guided by automatically inferring one or more partial specifications of intended program behaviors and program structure; b) biasing one or more repair choices guided by typical programming mistakes; and c) prioritizing the repair solutions based on error locations and possible changes in program semantics.
