 | ==== | 
 |  | 
 | Data to copy to export buffers. This is an optional operand. Must be specified as :ref:`off<amdgpu_synid_off>` if not used. | 
 |  | 
 | The :ref:`compr<amdgpu_synid_compr>` modifier indicates the use of compressed (16-bit) data, thus decreasing the number of source operands from 4 to 2: | 
 |  | 
 | * src0 and src1 must specify the first register (or :ref:`off<amdgpu_synid_off>`). | 
 | * src2 and src3 must specify the second register (or :ref:`off<amdgpu_synid_off>`). |
