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
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
