      fix issue #188 · 22ab5177
      MARCHE Claude authored
      the beginner transformation `split_vc` is now using `introduce_premises`
      followed by `subst_all`, instead of `simplify_trivial_quantification`
      followed by `introduce_premises`.
      
      following Andrei's suggestion, instead of `subst_all` we instead substitute
      only the symbols that (1) were introduced earlier and (2) do not have
      any attributes `[@model...]` so as to keep symbols present in the initial
      code.

      new VC to prove well-foundedness of user-provided variants · 4af9081d
      Jean-Christophe Filliatre authored
      fixes issue #57
      
      a new theory relations.WellFounded is introduced for this purpose
      (and must be imported whenever one wants to make use of a custom
      relation for a variant)
      
      it defines, inductively, a notion of accessibility for a given
      predicate R (x is accessible whenever all elements smaller than x for R
      are alreay accessible)
      
      whenever one has to prove that a variant decreases, a new VC is also
      generated, to show that the old value of the variant is accessible
      for the order relation
      
      note: accessibility being defined inductively, proving well-foundedness
      is out of reach of SMT solvers; but at least this is sound now
