[Frama-c-discuss] wp calculus



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.
