We follow the recipe of the
Decidable
instance for bitvectors and create aDecidableRelation
instance,This was motivated by a case-bash that was used to prove a
sdiv
lemma at width 1. However, due to file ordering constraints, we cannot use theDecidableRel
machinery to implement the lemmasdiv_eq_and
.Regardless, we upstream the
DecidableRel
machinery for future use.
