Frama-C API - `Defs`

Interface for the Scope plugin.

val get_defs : Frama_c_kernel.Kernel_function.t -> Frama_c_kernel.Cil_types.stmt -> Frama_c_kernel.Cil_types.lval -> (Frama_c_kernel.Cil_datatype.Stmt.Hptset.t * Frama_c_kernel.Locations.Zone.t option) option

returns
the set of statements that define lval before stmt in kf. Also returns the zone that is possibly not defined. Can return None when the information is not available (Pdg missing).

val get_defs_with_type : Frama_c_kernel.Kernel_function.t -> Frama_c_kernel.Cil_types.stmt -> Frama_c_kernel.Cil_types.lval -> ((bool * bool) Frama_c_kernel.Cil_datatype.Stmt.Map.t * Frama_c_kernel.Locations.Zone.t option) option

returns
a map from the statements that define lval before stmt in kf. The first boolean indicates the possibility of a direct modification at this statement, ie. lval = ... or lval = f(). The second boolean indicates a possible indirect modification through a call. Also returns the zone that is possibly not defined. Can return None when the information is not available (Pdg missing).

val compute_with_def_type_zone : Frama_c_kernel.Cil_types.kernel_function -> Frama_c_kernel.Cil_types.stmt -> Frama_c_kernel.Locations.Zone.t -> ((bool * bool) Frama_c_kernel.Cil_datatype.Stmt.Map.t * Frama_c_kernel.Locations.Zone.t option) option
