[Frama-c-discuss] Weakest precondition calculation

Hi
What about if you pack your formula into an ACSL requires clause, and then ask the WP for generating the associated proof-obligation(s) ?
You can access those features programmatically via the WP’s API, available online ( API Documentation <http://frama-c.com/download/frama-c-Sulfur-20171101_api.tar.gz> ).
To starts with, consider using, from module Wp.VC :

type t 
elementary proof obligation
val generate_ip : ?model:string -> Property.t -> t <file:///Users/correnson/Downloads/frama-c-api/wp/Wp.VC.html#TYPEt> Bag.t <file:///Users/correnson/doc/code/html/Bag.html#TYPEt>
val get_formula : t <file:///Users/correnson/Downloads/frama-c-api/wp/Wp.VC.html#TYPEt> -> Wp.Lang.F.pred <file:///Users/correnson/Downloads/frama-c-api/wp/Wp.Lang.F.html#TYPEpred>

Regards,
	L.
