[Frama-c-discuss] Why wp plugin failed to prove such naive properties?

CEA has a plug-in that allows to put annotations in a file separated
from the code (I don't know to which extent, i.e. would it allow to
add loop invariant?). Unfortunately this plug-in is proprietary.

That's said, I am wondering if open source project would not accept
patches for annotations. After all, Frama-C is open source (so anybody
can replay the verification) and annotations are in comments (so no
impact on binary). If it brings additional guarantees on the code, a
reasonable maintainer should accept such annotations. Have you tried
to send annotations upstream?

Best regards,
david
