[Frama-c-discuss] Frama-C/WP and CVC4 (version 1.5)

Hi Jens,

WP can generate PO in coq, altergo (default) or why3 formats.
The translation into "smtlib2 format" should be done using why3 (as it 
is done when using -wp-prover why3:cvc4).
May be you have to select a prover managed by why3 using the option 
"-wp-prover why3:cvc4" in addition to "-wp-gen"

Nothing to do with your question, but notice that Alt-Ergo can be used 
directly (-wp-prover alt-ergo) or through why3 (-wp-prover 
why3:alt-ergo). The POs given to Alt-Ergo are not the same.

The best way to keep the temporary files sent to the provers is to use 
the option: -wp-out <dir>.

Hope it helps,
Patrick.
