This avoids undefined behaviour in the shader, which will fail validation added later in the series. shader-db results are neglible -- the extra moves required in a few cases are cancelled out by the extra moves eliminated by allowing register allocation to work properly. total instructions in shared programs: 146903 -> 146907 (<.01%) instructions in affected programs: 33 -> 37 (12.12%) helped: 0 HURT: 1 total tuples in shared programs: 123616 -> 123613 (<.01%) tuples in affected programs: 764 -> 761 (-0.39%) helped: 6 HURT: 4 helped stats (abs) min: 1.0 max: 4.0 x̄: 1.67 x̃: 1 helped stats (rel) min: 0.54% max: 5.88% x̄: 2.64% x̃: 1.86% HURT stats (abs) min: 1.0 max: 2.0 x̄: 1.75 x̃: 2 HURT stats (rel) min: 4.55% max: 13.33% x̄: 8.57% x̃: 8.19% 95% mean confidence interval for tuples value: -1.73 1.13 95% mean confidence interval for tuples %-change: -2.72% 6.41% Inconclusive result (value mean confidence interval includes 0). total clauses in shared programs: 25656 -> 25654 (<.01%) clauses in affected programs: 43 -> 41 (-4.65%) helped: 2 HURT: 1 helped stats (abs) min: 1.0 max: 2.0 x̄: 1.50 x̃: 1 helped stats (rel) min: 6.25% max: 12.50% x̄: 9.38% x̃: 9.38% HURT stats (abs) min: 1.0 max: 1.0 x̄: 1.00 x̃: 1 HURT stats (rel) min: 33.33% max: 33.33% x̄: 33.33% x̃: 33.33% total cycles in shared programs: 12114.21 -> 12114.12 (<.01%) cycles in affected programs: 27.42 -> 27.33 (-0.30%) helped: 4 HURT: 3 helped stats (abs) min: 0.04166700000000034 max: 0.08333299999999966 x̄: 0.06 x̃: 0 helped stats (rel) min: 0.57% max: 1.59% x̄: 1.02% x̃: 0.96% HURT stats (abs) min: 0.0416669999999999 max: 0.08333299999999999 x̄: 0.06 x̃: 0 HURT stats (rel) min: 4.17% max: 16.67% x̄: 8.80% x̃: 5.56% 95% mean confidence interval for cycles value: -0.07 0.05 95% mean confidence interval for cycles %-change: -2.90% 9.27% Inconclusive result (value mean confidence interval includes 0). total arith in shared programs: 4601.08 -> 4601.04 (<.01%) arith in affected programs: 29 -> 28.96 (-0.14%) helped: 6 HURT: 4 helped stats (abs) min: 0.04166700000000001 max: 0.08333299999999966 x̄: 0.06 x̃: 0 helped stats (rel) min: 0.57% max: 10.00% x̄: 3.63% x̃: 1.39% HURT stats (abs) min: 0.04166700000000001 max: 0.08333399999999991 x̄: 0.07 x̃: 0 HURT stats (rel) min: 5.56% max: 16.67% x̄: 10.85% x̃: 10.60% 95% mean confidence interval for arith value: -0.05 0.05 95% mean confidence interval for arith %-change: -3.95% 8.28% Inconclusive result (value mean confidence interval includes 0). total quadwords in shared programs: 110008 -> 110002 (<.01%) quadwords in affected programs: 1090 -> 1084 (-0.55%) helped: 11 HURT: 8 helped stats (abs) min: 1.0 max: 7.0 x̄: 2.18 x̃: 1 helped stats (rel) min: 0.61% max: 13.16% x̄: 4.07% x̃: 1.82% HURT stats (abs) min: 1.0 max: 6.0 x̄: 2.25 x̃: 1 HURT stats (rel) min: 3.70% max: 42.86% x̄: 12.55% x̃: 7.50% 95% mean confidence interval for quadwords value: -1.76 1.13 95% mean confidence interval for quadwords %-change: -2.95% 8.81% Inconclusive result (value mean confidence interval includes 0).

`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.
