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: 817327 -> 815717 (-0.20%) instructions in affected programs: 755504 -> 753894 (-0.21%) helped: 73 HURT: 1 helped stats (abs) min: 1 max: 159 x̄: 22.12 x̃: 14 helped stats (rel) min: 0.05% max: 0.40% x̄: 0.22% x̃: 0.23% HURT stats (abs) min: 5 max: 5 x̄: 5.00 x̃: 5 HURT stats (rel) min: 0.07% max: 0.07% x̄: 0.07% x̃: 0.07% 95% mean confidence interval for instructions value: -27.27 -16.24 95% mean confidence interval for instructions %-change: -0.24% -0.20% Instructions are helped. total cycles in shared programs: 6822826 -> 6820707 (-0.03%) cycles in affected programs: 6390844 -> 6388725 (-0.03%) helped: 71 HURT: 3 helped stats (abs) min: 2 max: 537 x̄: 30.72 x̃: 18 helped stats (rel) min: <.01% max: 0.08% x̄: 0.03% x̃: 0.03% HURT stats (abs) min: 10 max: 32 x̄: 20.67 x̃: 20 HURT stats (rel) min: 0.01% max: 0.02% x̄: 0.02% x̃: 0.02% 95% mean confidence interval for cycles value: -43.41 -13.86 95% mean confidence interval for cycles %-change: -0.04% -0.03% 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>`_).
