Given that our fcsels are on float-bools, we can emit the LRP directly and save the backend having to emit a SLT to turn the CMP src[0] into a bool. This required passing a codegen flags struct for nir-to-tgsi. I think this is a good way forward for it, as the alternative I think has mostly been adding flags to nir_shader_compiler_options (since adding PIPE_SHADER_CAPs is an unreasonable amount of pain). r300 shader-db: total instructions in shared programs: 1484320 -> 1472463 (-0.80%) instructions in affected programs: 243588 -> 231731 (-4.87%) total temps in shared programs: 212485 -> 212143 (-0.16%) temps in affected programs: 3845 -> 3503 (-8.89%) Acked-by: Pavel Ondračka <pavel.ondracka@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14886>

Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
