Image data to load by an image_gather4 instruction.
Size: 4 data elements by default. Each data element occupies either 32 bits or 16 bits depending on :ref:`d16<amdgpu_synid_d16>`.
:ref:`d16<amdgpu_synid_d16>` and :ref:`tfe<amdgpu_synid_tfe>` affect operand size as follows:
- :ref:`d16<amdgpu_synid_d16>` specifies that data elements in registers are packed; each value occupies 16 bits.
- :ref:`tfe<amdgpu_synid_tfe>` adds one dword if specified.
Operands: :ref:`v<amdgpu_synid_v>`
