//META: purpose=RWTexture2D<uint4> emits OpTypeImage with sampled type %uint and image format Rgba32ui (resolveTextureFormat sets the format from the Slang element type).
//META: intent=expansion
//META: pipeline_stage=ir-pass
//META: warning=Auto-generated. May drift from source. Do not edit by hand.

// Expansion: the sampled-type axis of OpTypeImage. Switching the
// Slang element type from float4 to uint4 flips the SPIR-V sampled
// type from %float to %uint AND populates the Image Format field
// (Rgba32ui) instead of Unknown. resolveTextureFormat (Phase C
// pass #2) is what fills that format slot for storage images.
