ABSTRACT
This article presents a new numerical abstract domain for static analysis by abstract interpretation. It extends our previously proposed DBM-based numerical abstract domain and allows us to represent invariants of the form (\pm x \pm y lleq c), where x and y are program variables and c is a real constant.We focus on giving an efficient representation based on Difference-Bound Matrices - O(n^2) memory cost, where n is the number of variables - and graph-based algorithms for all common abstract operators - O(n^3) time cost. This includes a normal form algorithm to test equivalence of representation and a widening operator to compute least fixpoint approximations.
