----------------
According to OpenCL 2.0 (page 46 of https://www.khronos.org/registry/cl/specs/opencl-2.0-openclc.pdf):

The sampler-less read image and write image built-ins can be used with image declared with the __read_write (or read_write) qualifier. Calls to built-ins that read from an image using a sampler for images declared with the __read_write (or read_write) qualifier will be a compilation error.
