Variable prog: Csyntax.program.
Variable tprog: Clight.program.
Hypothesis TRANSL: match_prog prog tprog.
Let ge := Csem.globalenv prog.
Let tge := Clight.globalenv tprog.
(** Invariance properties. *)
Proof (Genv.find_symbol_match (proj1 TRANSL)).
Proof (Genv.senv_match (proj1 TRANSL)).

Lemma function_ptr_translated:

Genv.find_funct_ptr ge b = Some f ->
exists tf,
Genv.find_funct_ptr tge b = Some tf /\ tr_fundef f tf.
