      Q817-011 proof - integrate float enabled cvc4 · 2ff5ad5f
      Sylvain Dailler authored
      Generic BV cleanup.
      
      BitVector theory:
      * Express to_int in terms of to_uint and a new predicate
        is_signed_positive. I can't use sge directly because it has not been
        introduced yet, and it can't be re-ordered as it uses to_int.
      
      * Add new axiom to link the two.
      
      Generic BitVector driver:
      * Re-ordering of the BV driver to match the theory.
      * Remove to_uint_of_int axiom.
      * Remove the new axiom linking is_signed_positive and sge.
      
      Z3:
      * Refactor Z3 specific BV driver, similar to what is done with CVC4. Make
        a note that explains Z3's bv2int is actually bv2nat despite
        the name.
      
      CVC4:
      * Simplify its BV driver slightly by moving to_uint printer into bv_gen.

      * declare range types and float types,
      * use integer (resp. real) literals for those types through casting,
      * specify how to print them in drivers.
      
      Change in syntax
      * use
      
        type t = < range 1 2 >   (* integers from 1 to 2 *)
        type t' = < float 4 12 > (* float with 4 bits in exponent and 12 in mantissa *)
      
        the two projections :
        t'int
        t''real
      
        and the predicate :
        t''isFinite
      
      * Restrict the use of "'" in whyml:
        Users are not allowed to introduce names where a quote symbol
        is followed by a letter. Thus, the following identifiers are
        valid:
      
        t'
        toto'0''
        toto'_phi
      
        whereas toto'phi is not.
      
      Note: we do not yet support negative numbers in range declaration
      and casting of a literal.
