//META: purpose=`rwbuf.Load(idx)` on a `RWStructuredBuffer<float4>` produces `rwstructuredBufferLoad(%buf, %idx)` with a vector result type, demonstrating the variadic-min-2 operand shape.
//META: intent=functional
//META: pipeline_stage=lower
//META: warning=Auto-generated. May drift from source. Do not edit by hand.

// The doc lists `rwstructuredBufferLoad` as variadic with `min=2`
// (buffer + index); the result type matches the buffer's element
// type. Exercise the vector-element form.
