</h3>



<div>



<p>The PTX back-end has been replaced by the NVPTX back-end, which is based on

   the LLVM back-end used by NVIDIA in their CUDA (nvcc) and OpenCL compiler.

   Some highlights include:</p>

<ul>

  <li>Compatibility with PTX 3.1 and SM 3.5</li>

  <li>Support for NVVM intrinsics as defined in the NVIDIA Compiler SDK</li>

  <li>Full compatibility with old PTX back-end, with much greater coverage of

      LLVM IR</li>

</ul>



<p>Please submit any back-end bugs to the LLVM Bugzilla site.</p>
