|0002371||Frama-C||Plug-in > wp||public||2018-03-22 12:35||2018-03-26 09:39|
|Platform||Sulfur-20171101||OS||OS Version||Ubuntu 17.10|
|Product Version||Frama-C 16 Sulfur|
|Target Version||Fixed in Version|
|Summary||0002371: suggest to provide results of commandl-line "-wp-prop" evaluation in a file in the wp-out directory|
|Description||I ran |
"frama-c -wp -wp-out without_lemma -wp-gen -wp-prover why3 -wp-prop=-@lemma aaa.c"
"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. 0002285).
|Tags||No tags attached.|
|Attached Files||aaa.c [^] (198 bytes) 2018-03-22 12:35 [Show Content]|
Such features will be, indeed, implemented as part of the new generation engine we are working on.
More precisely, we are planning to integrate more closely Frama-C/WP and Why3 session. Hence,
the data (and dependencies) you are asking for will be directly implemented in terms of Why3 tasks.
