--- Comment #7 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
While the statements after a RETURN are still there in the dump file *.007t.eh,
they are removed at *.008t.cfg

...
Removing basic block 3
;; basic block 3, loop depth 0
;;  pred:      
undefined ();
...

So I am convinced that this PR should be marked as a duplicate of pr46476. If
for "good" reason (I don't understand) you want a special warning for procedure
removal, I think this should be asked in pr46476.
