4// This tests that combined texture sampler objects which have D3D style register assignments, but no vk::binding,
5// show an appropriate warning.
6// The warning should appear even if the user used -fvk-xxx-shift options, because those options do not serve to map
7// two register assignments of different types into a single vulkan binding.
