// RUN: %dxc -E main -T ps_6_0 -Vd -validator-version 0.0 %s | %D3DReflect %s | FileCheck %s

// -Vd -validator-version 0.0 is used to keep the reflection information
// in the actual module containing the cbuffer/tbuffer usage info.
// This is only necessary for test path at the moment because of the way
// the IR gets into D3DReflect by way of module disassembly and reassembly.
// Otherwise the separate reflection blob would correctly contain the usage information,
// since the metadata there is not gated on the shader target.
