ALU only. Intended to clean up the lowerings used with complex texturings. Ex: if a shader reads two cube maps at the same coordinates, this deduplicates the cube map transformation. This needs to happen in the backend since we do the cube map transformation with the backend builder, rather than special NIR ops. This is a tradeoff. Pass based on ir3's, which in turn is inspired by NIR's. total instructions in shared programs: 148799 -> 147348 (-0.98%) instructions in affected programs: 20509 -> 19058 (-7.07%) helped: 145 HURT: 0 helped stats (abs) min: 4.0 max: 30.0 x̄: 10.01 x̃: 8 helped stats (rel) min: 1.92% max: 54.55% x̄: 10.87% x̃: 7.41% 95% mean confidence interval for instructions value: -10.73 -9.28 95% mean confidence interval for instructions %-change: -12.81% -8.94% Instructions are helped. total tuples in shared programs: 129992 -> 128908 (-0.83%) tuples in affected programs: 17624 -> 16540 (-6.15%) helped: 145 HURT: 0 helped stats (abs) min: 2.0 max: 25.0 x̄: 7.48 x̃: 7 helped stats (rel) min: 0.74% max: 42.86% x̄: 9.16% x̃: 7.22% 95% mean confidence interval for tuples value: -7.96 -6.99 95% mean confidence interval for tuples %-change: -10.52% -7.79% Tuples are helped. total clauses in shared programs: 27632 -> 27582 (-0.18%) clauses in affected programs: 1077 -> 1027 (-4.64%) helped: 44 HURT: 0 helped stats (abs) min: 1.0 max: 3.0 x̄: 1.14 x̃: 1 helped stats (rel) min: 2.50% max: 16.67% x̄: 4.99% x̃: 4.45% 95% mean confidence interval for clauses value: -1.26 -1.01 95% mean confidence interval for clauses %-change: -5.70% -4.27% Clauses are helped. total cycles in shared programs: 12323 -> 12285.63 (-0.30%) cycles in affected programs: 618.25 -> 580.88 (-6.05%) helped: 120 HURT: 0 helped stats (abs) min: 0.08333299999999966 max: 0.5416680000000014 x̄: 0.31 x̃: 0 helped stats (rel) min: 0.77% max: 66.67% x̄: 7.60% x̃: 7.37% 95% mean confidence interval for cycles value: -0.33 -0.29 95% mean confidence interval for cycles %-change: -8.73% -6.47% Cycles are helped. total arith in shared programs: 4916.75 -> 4866.88 (-1.01%) arith in affected programs: 677.79 -> 627.92 (-7.36%) helped: 145 HURT: 0 helped stats (abs) min: 0.08333299999999966 max: 1.0833329999999997 x̄: 0.34 x̃: 0 helped stats (rel) min: 0.77% max: 66.67% x̄: 12.81% x̃: 7.87% 95% mean confidence interval for arith value: -0.37 -0.32 95% mean confidence interval for arith %-change: -15.33% -10.29% Arith are helped. total quadwords in shared programs: 118117 -> 117262 (-0.72%) quadwords in affected programs: 15283 -> 14428 (-5.59%) helped: 143 HURT: 0 helped stats (abs) min: 1.0 max: 23.0 x̄: 5.98 x̃: 5 helped stats (rel) min: 0.44% max: 25.71% x̄: 7.56% x̃: 5.56% 95% mean confidence interval for quadwords value: -6.46 -5.50 95% mean confidence interval for quadwords %-change: -8.59% -6.53% Quadwords are helped.

`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. 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.
