val mem_project : (Project_skeleton.t -> bool) -> t -> bool

mem_project f x must return true iff there is a value p of type Project.t in x such that f p returns true.

val copy : t -> t

Deep copy: no possible sharing between x and copy x.

val join : froms -> froms -> froms

val top : froms

val pretty_with_type : Cil_types.typ -> froms Pretty_utils.formatter

Display dependencies of a function, using the function's type to improve readability

val pretty_with_type_indirect : Cil_types.typ -> froms Pretty_utils.formatter

Display dependencies of a function, using the function's type to improve readability, separating direct and indirect dependencies

val outputs : froms -> Locations.Zone.t

Extract the left part of a from result, ie. the zones that are written

val inputs : ?include_self:bool -> froms -> Locations.Zone.t

Extract the right part of a from result, ie. the zones on which the written zones depend. If include_self is true, and the from is of the form x FROM y (and SELF), x is added to the result; default value is false.
