val get_data_scope_at_stmt : Kernel_function.t ->
       Cil_types.stmt ->
       Cil_types.lval ->
       Cil_datatype.Stmt.Hptset.t *
       (Cil_datatype.Stmt.Hptset.t * Cil_datatype.Stmt.Hptset.t)

Raises Kernel_function.No_Definition if kf has no definition.
Returns 3 statement sets related to the value of lval before stmt :
- the forward selection,
- the both way selection,
- the backward selection.

val get_prop_scope_at_stmt : Cil_types.kernel_function ->
       Cil_types.stmt ->
       Cil_types.code_annotation ->
       Cil_datatype.Stmt.Hptset.t * Cil_types.code_annotation list

compute the set of statements where the given annotation has the same value as before the given stmt. Also returns the eventual code annotations that are implied by the one given as argument.

val check_asserts : unit -> Cil_types.code_annotation list

Print how many assertions could be removed based on the previous analysis (get_prop_scope_at_stmt) and return the annotations that can be removed.

val rm_asserts : unit -> unit

Same analysis than check_asserts but mark the assertions as proven.
