Hello, 2013/9/3 David MENTRE <dmentre at linux-france.org>: > 2013/9/3 Rovedy Aparecida Busquim e Silva <rovedy at ig.com.br>: >> We are using the Carbon version. > > Your Inic2 contract is fully proved by WP with Frama-C Fluorine (June) > and Alt-Ergo 0.95.1. You'd better upgrade your Frama-C version. > It'd be indeed a good idea to upgrade, as Carbon is showing its age, but be careful that by default WP computes on reals (see WP manual, section 1.5). With the following command line: frama-c -wp -pp-annot float.c -wp-model +float alt-ergo does not prove any ensures. On the other hand, with frama-c -wp -pp-annot float.c -wp-model +float -wp-proof why3:gappa gappa succeeds in discharging all 3 ensures. Best regards, -- E tutto per oggi, a la prossima volta Virgile
