WpReached (frama-c-wp.Wp.WpReached)

type reachability

control flow graph dedicated to smoke tests

val is_predicate : bool -> Frama_c_kernel.Cil_types.predicate -> bool

If returns true the predicate has always the given boolean value.

val is_dead_annot : Frama_c_kernel.Cil_types.code_annotation -> bool

False assertions and loop invariant. Hence, also includes completely unrolled loop.

val is_dead_code : Frama_c_kernel.Cil_types.stmt -> bool

Checks whether the stmt has a dead-code annotation.

val reachability : Frama_c_kernel.Kernel_function.t -> reachability

memoized reached cfg for function

val smoking : reachability -> Frama_c_kernel.Cil_types.stmt -> bool

Returns whether a stmt need a smoke tests to avoid being unreachable. This is restricted to assignments, returns and calls not dominated another smoking statement.
