You can reproduce it e.g. with

  .../piglit/bin/depth-tex-modes-glsl -auto -fbo

Set the environment variable `AMD_DEBUG=ps,preoptir,nonir,checkir,mono` to get the LLVM IR on stderr (may need to replace `ps` according to the affected shader type, run with `AMD_DEBUG=help` for a list of all supported debugging options).
