I ran "frama-c -wp -wp-out without_lemma -wp-gen -wp-prover why3 -wp-prop=-@lemma aaa.c" and then "frama-c -wp -wp-out with_lemma -wp-gen -wp-prover why3 aaa.c" on the attached file. After that, "diff -r without_lemma with_lemma" reports no difference between both generated directories.
It is clear that Frama-C needs to generate why3 code for the lemma in both cases, since it might be used in some proof.
However, as a consequence, there is no information in the generated directories about which lemmas should be proven. It would be nice if in the long run such information could be provided, e.g. in a separate file.
Additional Information :
Our application scenario is the following:
We run (one of) the above command(s) on a local computer to generate why3 files; then we transfer them to a more powerful remote computer, and run the provers there. On the remote computer, we would like to have the list of lemmas-to-be-proven available.
Note that arbitrarily complex combinations of "-wp-prop" could exclude some lemmas from being proven and include others. Therefore, we don't want to perform the evaluation of command-line args "-wp-prop=..." ourselves again (this is difficult, anyway, cf. #2285).
