val select_func_calls_to : set -> spare:bool -> Cil_types.kernel_function -> set

val select_stmt_internal : Cil_types.kernel_function ->
?select:t -> Cil_types.stmt -> Api.Mark.t -> t
Internally used to select a statement :
is_ctrl_mark m
,
propagate ctrl_mark on ctrl dependencies of the statementis_addr_mark m
,
propagate addr_mark on addr dependencies of the statementis_data_mark m
,
propagate data_mark on data dependencies of the statement
Marks the node with a spare_mark and propagate so that the dependencies
that were not selected yet will be marked spare.
When the statement is a call, its functional inputs/outputs are also
selected (The call is still selected even it has no output).
When the statement is a composed one (block, if, etc...),
all the sub-statements are selected.SlicingTypes.NoPdg
when the Pdg cannot be computed.val select_label_internal : Cil_types.kernel_function ->
?select:t -> Cil_types.logic_label -> Api.Mark.t -> t
val select_min_call_internal : Cil_types.kernel_function ->
?select:t -> Cil_types.stmt -> Api.Mark.t -> t
Internally used to select a statement call without its
inputs/outputs so that it doesn't select the statements computing the
inputs of the called function as select_stmt_internal
would do.
Raise Invalid_argument
when the stmt
isn't a call.
SlicingTypes.NoPdg
when the Pdg cannot be computed.val select_stmt_zone_internal : Cil_types.kernel_function ->
?select:t ->
Cil_types.stmt ->
before:bool -> Locations.Zone.t -> Api.Mark.t -> t
Internally used to select a zone value at a program point.
SlicingTypes.NoPdg
when the Pdg cannot be computed.val select_zone_at_entry_point_internal : Cil_types.kernel_function ->
?select:t -> Locations.Zone.t -> Api.Mark.t -> t
Internally used to select a zone value at the beginning of a function.
For a defined function, it is similar to select_stmt_zone_internal
with the initial statement, but it can also be used for undefined
functions.
SlicingTypes.NoPdg
when the Pdg cannot be computed.val select_zone_at_end_internal : Cil_types.kernel_function ->
?select:t -> Locations.Zone.t -> Api.Mark.t -> t
Internally used to select a zone value at the end of a function.
For a defined function, it is similar to select_stmt_zone_internal
with the return statement, but it can also be used for undefined
functions.
SlicingTypes.NoPdg
when the Pdg cannot be computed.val select_modified_output_zone_internal : Cil_types.kernel_function ->
?select:t -> Locations.Zone.t -> Api.Mark.t -> t
Internally used to select the statements that modify the given zone considered as in output. Be careful that it is NOT the same as selecting the zone at the end! The 'undef' zone is not propagated...
SlicingTypes.NoPdg
when the Pdg cannot be computed.val select_stmt_ctrl_internal : Cil_types.kernel_function ->
?select:t -> Cil_types.stmt -> t
Internally used to select a statement reachability : Only propagate a ctrl_mark on the statement control dependencies.

Internally used to select PDG nodes :

,
propagate ctrl_mark on ctrl dependencies of the statementis_addr_mark m
,
propagate addr_mark on addr dependencies of the statementis_data_mark m
,
propagate data_mark on data dependencies of the statement
Marks the node with a spare_mark and propagate so that
the dependencies that were not selected yet will be marked spare.val pretty : Stdlib.Format.formatter -> t -> unit
