Reachability for Smoke Tests
type
reachability
control flow graph dedicated to smoke tests
val is_predicate : bool -> Cil_types.predicate -> bool
If returns true
the predicate has always the given boolean value.
val is_dead_annot : Cil_types.code_annotation -> bool
False assertions and loop invariant. Hence, also includes completely unrolled loop.
val is_dead_code : Cil_types.stmt -> bool
Checks whether the stmt has a dead-code annotation.
val reachability : Kernel_function.t -> reachability
memoized reached cfg for function
val smoking : reachability -> 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.
