This is a generic algebraic optimization. Use the generic algebraic optimizer. The only reason we can't rely on nir_opt_algebraic to do this is because we generate inot's late in order to optimize some comparisons. But we already have a pass to clean that up (midgard_nir_clean_inot), it just needs to be extended to handle more cases. shader-db is noise: total bundles in shared programs: 646941 -> 646942 (<.01%) bundles in affected programs: 100 -> 101 (1.00%) helped: 0 HURT: 1 total quadwords in shared programs: 1134727 -> 1134726 (<.01%) quadwords in affected programs: 318 -> 317 (-0.31%) helped: 2 HURT: 1 total registers in shared programs: 90619 -> 90618 (<.01%) registers in affected programs: 12 -> 11 (-8.33%) helped: 1 HURT: 0 Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Reviewed-by: Italo Nicola <italonicola@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/23769>
`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. 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.
