PostHat and All That: Attaining Most-Precise Inductive Invariants
In abstract interpretation, the choice of an abstract domain fixes a limit on the precision of the inductive invariants that one can express; however, for a given abstract domain A, there is a most-precise (``strongest'', ...
An Abstract Domain for Bit-Vector Inequalities
(University of Wisconsin-Madison Department of Computer Sciences, 2013-04-16)
This paper advances the state of the art in abstract interpretation of machine code. It tackles two of the biggest challenges in machine-code analysis: (1) holding onto invariants about values in memory, and (2) identifying ...
