text {*
The operations @{text div} and @{text mod} are built-in in Boogie, but
without a particular semantics due to different interpretations in
programming languages. We assume that each application comes with a
proper axiomatization.

axiomatization
  boogie_div :: "int \<Rightarrow> int \<Rightarrow> int" (infixl "div'_b" 70) and
  boogie_mod :: "int \<Rightarrow> int \<Rightarrow> int" (infixl "mod'_b" 70)
