However, there exists a hack that can allow you to take advantage of Why3's own session mechanism. Given the necessary steps, I'm afraid this is not exactly robust, but you might nevertheless be interested in the approach. This uses the GUI, but it might be possible to write a quick and dirty script that performs the file operations in batch mode. 1) generate POs without launching provers: frama-c-gui [your options] -wp-prover none file.c 2) in the WP proofs panel of the GUI, launch Why3 on a PO: this should give you a Why3 session with all the PO attached to a given function. 3) Use whatever provers and strategies you want in Why3 and save the Why3 session before quitting Why3 and Frama-C 4) copy the why3session.xml in ~/.frama-c-wp/project-session into somewhere safe 5) redo step 1 6) copy why3session.xml into ~/.frama-c-wp/project-session from the place where you stored it. 7) redo step 2: Why3 should read why3session.xml and reuse the proofs of the PO whose statement has not changed since step 3.
