We abstract a denotational trace semantics for an imperative language into a compositional and focussed watchpoint semantics. Every abstraction of its computational domain induces an abstract, still compositional and focussed watchpoint semantics. We describe its implementation and instantiation with a domain of signs. It shows that its space and time costs are proportional to the number of watchpoints and that abstract compilation reduces those costs significantly.

Abstract
We abstract a denotational trace semantics for an imperative language into a compositional and focussed watchpoint semantics. Every abstraction of its computational domain induces an abstract, still compositional and focussed watchpoint semantics. We describe its implementation and instantiation with a domain of signs. It shows that its space and time costs are proportional to the number of watchpoints and that abstract compilation reduces those costs significantly.
