To vectorize to vec8/16 or vec4 (without vec3), we can't incrementally add components to a load/store. This patch loops vectorization so that two new vec2/4/8 operations can be combined into a larger operation. fossil-db (GFX10.3): Totals from 22 (0.02% of 139391) affected shaders: SpillVGPRs: 1749 -> 1771 (+1.26%) CodeSize: 901212 -> 892532 (-0.96%); split: -1.19%, +0.22% Scratch: 178176 -> 184320 (+3.45%) Instrs: 159358 -> 158027 (-0.84%); split: -0.99%, +0.16% Cycles: 37046772 -> 36738544 (-0.83%); split: -1.00%, +0.17% Signed-off-by: Rhys Perry <pendingchaos02@gmail.com> Reviewed-by: Eric Anholt <eric@anholt.net> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10384> |

`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 `Freenode's #dri-devel <irc://chat.freenode.net#dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
