Hi, This is far from being a trivial task, since *the* weakest precondition is not something uniquely defined. In Frama/C/Jessie/Why tool chain, or in Caduceus/Why toolchain, the WP is computed with respect to some memory model for C, which might not be to one you expect. You can have a look at the other Frama-C plugin called "WP", which performs wp computation directly at the C level, and is parameterized by several possible memory models. - Claude Mauro Baluda wrote: > I'm looking for a tool able to calculate weakest preconditions for c > statements given a postcondition > I think Why does this internally (src/wp.ml), is it possible to > interact with the precondition calculator programmatically or using > the command line? > > thanks, > Mauro > > _______________________________________________ > Why-discuss mailing list > Why-discuss at lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/why-discuss -- Claude March? | tel: +33 1 72 92 59 69 INRIA Saclay - ?le-de-France | mobile: +33 6 33 14 57 93 Parc Orsay Universit? | fax: +33 1 74 85 42 29 4, rue Jacques Monod - B?timent N | http://www.lri.fr/~marche/ F-91893 ORSAY Cedex |
