The main purpose of this commit is to prepare for "soft-fp64/fadd: Move common code out of both branches of an if-statement". Results on the 308 shaders extracted from the fp64 portion of the OpenGL CTS: Tiger Lake and Ice Lake had similar results. (Tiger Lake shown) total instructions in shared programs: 812590 -> 812094 (-0.06%) instructions in affected programs: 672135 -> 671639 (-0.07%) helped: 57 HURT: 0 helped stats (abs) min: 1 max: 32 x̄: 8.70 x̃: 7 helped stats (rel) min: <.01% max: 0.49% x̄: 0.12% x̃: 0.09% 95% mean confidence interval for instructions value: -10.46 -6.94 95% mean confidence interval for instructions %-change: -0.15% -0.09% Instructions are helped. total cycles in shared programs: 6798039 -> 6797157 (-0.01%) cycles in affected programs: 5810059 -> 5809177 (-0.02%) helped: 54 HURT: 2 helped stats (abs) min: 2 max: 68 x̄: 16.44 x̃: 12 helped stats (rel) min: <.01% max: 0.12% x̄: 0.03% x̃: 0.02% HURT stats (abs) min: 2 max: 4 x̄: 3.00 x̃: 3 HURT stats (rel) min: <.01% max: <.01% x̄: <.01% x̃: <.01% 95% mean confidence interval for cycles value: -19.50 -12.00 95% mean confidence interval for cycles %-change: -0.03% -0.02% Cycles 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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
