//META: purpose=Boundary probe of the documented arithmetic family at its 1-operand member: unary `-a` produces a `neg(%a)` IR instruction.

// The doc lists `add`/`sub`/`mul`/`div` as the representative
// arithmetic family. Unary negation has a single-operand member,
// `neg`, in the same family — observable in the IR dump.
