Symbolic decision trees are not the only way to correlate the relationship between flags and numeric variables. Boolean formulae can also represent such relationships where the integer variables are modelled with bit-vectors of propositional variables. Boolean formulae can be composed to express the semantics of a block and program state, but they are hardly tractable, hence the need to compute their abstractions. This paper shows how incremental SAT can be applied to derive range and set abstractions for bit-vectors that are constrained by Boolean formulae.
