(* A simple control flow analysis for C statements.
Main purpose: emit warnings for _Noreturn functions. *)
val function_returns: Env.t -> C.stmt -> bool * bool

- the first says whether the function can return
- the second says whether the function can return by falling through
the end of its body.
Both are over-approximations. *)
