-/* \brief Backwards compatibility wrapper for IntImm arguments
- *
- * In previous versions of TVM, IntImm was the default FFI type for
- * integer arguments, instead of runtime::Int.  For backwards
- * compatibility where the callee has been updated to expected a
- * runtime::Int, the caller has not been updated to provide a
- * runtime::Int (e.g. relay script parsing), and the auto-unboxing of
- * runtime::Int does not apply (e.g. making an `Array<runtime::Int>`),
- * allow the IntImm to be generated.
