(** The offsets of [Outgoing] arguments are below [size_arguments s]. *)
Remark fold_max_outgoing_above:
forall l n, fold_left max_outgoing_2 l n >= n.

Lemma loc_arguments_bounded:
forall (s: signature) (ofs: Z) (ty: typ),
In (S Outgoing ofs ty) (regs_of_rpairs (loc_arguments s)) ->
ofs + typesize ty <= size_arguments s.
