Variable prog: RTL.program.
Variable tprog: LTL.program.
Hypothesis TRANSF: match_prog prog tprog.
Let ge := Genv.globalenv prog.
Let tge := Genv.globalenv tprog.
Proof (Genv.find_symbol_match TRANSF).
Proof (Genv.senv_match TRANSF).

Lemma functions_translated:
forall (v: val) (f: RTL.fundef),
Genv.find_funct ge v = Some f ->
exists tf,
Genv.find_funct tge v = Some tf /\ transf_fundef f = OK tf.
