    14891489SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler.
    14901490The first address register holds the Z-compare value.</p>
     1491<h4>IMAGE_SAMPLE_C_B</h4>
     1492<p>Opcode: 45 (0x2d)<br />
     1493Syntax: IMAGE_SAMPLE_C_B VDATA(1:4), VADDR(3:6), SRSRC(4,8), SSAMP(4)<br />
     1494Description: Get sampled pixel value from SRSRC image at address VADDR by using
     1495SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler.
     1496The first address register holds the Z-compare value.
     1497Next address register holds the LOD bias value.</p>
     1498<h4>IMAGE_SAMPLE_C_B_CL</h4>
     1499<p>Opcode: 46 (0x2e)<br />
     1500Syntax: IMAGE_SAMPLE_C_B_CL VDATA(1:4), VADDR(4:7), SRSRC(4,8), SSAMP(4)<br />
     1501Description: Get sampled pixel value from SRSRC image at address VADDR by using
     1502SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler.
     1503The first address register holds the Z-compare value. Next address register holds the
     1504LOD bias value. The last address register holds the clamp value.</p>

    14921506<p>Opcode: 41 (0x29)<br />
    … …  
    15171531The first address register holds the Z-compare value. The last address register holds
    15181532the LOD value.</p>

     1534<p>Opcode: 47 (0x2f)<br />
     1535Syntax: IMAGE_SAMPLE_C_LZ VDATA(1:4), VADDR(2:5), SRSRC(4,8), SSAMP(4)<br />
     1536Description: Get sampled pixel value from SRSRC image at address VADDR by using
     1537SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler.
     1538The first address register holds the Z-compare value. Force use of mipmap level 0 (???).</p>
