Class virtual Cumulative_analysis.cumulative_visitor

class virtual ['a] cumulative_visitor : object .. end

Frama-C visitor for cumulative analyses: we add a few useful methods. The method compute_kf must be used to add the effects of a call to the given kernel function to the pool of results

Inherits
method specialize_state_on_call : Cil_types.kernel_function -> Db.Value.state

If the current statement is a call to the given function, enrich the superposed memory state at this statement with the formal arguments of this function. Useful to do an analysis with a limited amount of context

method virtual compute_kf : Cil_types.kernel_function -> 'a

Virtual function to use when one needs to compute the effect of a function call. This function carries implicitly a context: thus calling self#compute_kf k1; self#compute_kf k2 is different from calling one within the other
