Hi,

In the new release of Why 2.35, the support for use of the former why VC
generator and the former graphical interface gwhy is completely dropped
out. In particular the former executables "why" and "gwhy" are not
compiled and not installed anymore.

It's true that the behavior of option -jessie-atp should be have been
changed too, sorry about that. Fortunately there is a workaround, as
described below.

First, let me say that the recommended way to prove a C program with
Jessie is:

1) first, discharge VCs using Why3 proof transformations and as many
provers as possible, using the GUI:

frama-c -jessie f.c

2) To replay the former proofs in batch mode, use

frama-c -jessie -jessie-atp=why3replay f.c

If for some reason you want to run a single prover on generated VCs,
then there is a workaround: you can somehow abuse the jessie options as
follows

frama-c -jessie -jessie-atp=why3ml -jessie-why3-opt="prove -P alt-ergo" f.c

This will not do the same as the former use of -jessie-atp, because Why3
does automatically split the conjunctions in the goal, so one should do
instead:

frama-c -jessie -jessie-atp=why3ml -jessie-why3-opt="prove -P alt-ergo
-a split_goal_wp" f.c

As you can guess, option -jessie-why3-opt allows you to pass any of the
options supported by Why3. For more advanced use, you should then look
at the description of all options in Why3's manual.

Finally, note that this "abuse" is not limited to the use of Why3's
"prove" subcommand. For example, one may produce an HTML dump of the
session by

frama-c -jessie -jessie-atp=why3ml -jessie-why3-opt="session html" f.c

The dump will be produced in file f.jessie/f/why3session.html

Hope this helps,

- Claude
