Variable f: Linear.function.
Let b := function_bounds f.
Let fe := make_env b.
Variable tf: Mach.function.
Hypothesis TRANSF_F: transf_function f = OK tf.

Lemma unfold_transf_function:
tf = Mach.mkfunction
f.(Linear.fn_sig)
(transl_body f fe)
fe.(fe_size)
(Ptrofs.repr fe.(fe_ofs_link))
(Ptrofs.repr fe.(fe_ofs_retaddr)).
