//META: purpose=A uniform `uint` plus the literal `1u` lowers to a runtime `add(%a, 1 : UInt)` instruction; lowering does not pre-compute the sum because one operand is non-constant.
//META: intent=boundary
//META: pipeline_stage=lower
//META: warning=Auto-generated. May drift from source. Do not edit by hand.

// Boundary: integer-arithmetic at the uint MAX + 1 edge, runtime
// form. Because `%a` is a uniform (not a compile-time literal), the
// IRBuilder cannot constant-fold `a + 1u` and emits an `add`
// instruction whose RHS is the literal `1 : UInt`.
