Previous condition checks already guaranteen that expDiff != 0 and !(expDiff > 0), so expDiff < 0 is the only option left. 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: 815491 -> 812590 (-0.36%) instructions in affected programs: 753668 -> 750767 (-0.38%) helped: 74 HURT: 0 helped stats (abs) min: 3 max: 281 x̄: 39.20 x̃: 25 helped stats (rel) min: 0.29% max: 0.73% x̄: 0.42% x̃: 0.40% 95% mean confidence interval for instructions value: -48.50 -29.91 95% mean confidence interval for instructions %-change: -0.45% -0.40% Instructions are helped. total cycles in shared programs: 6813681 -> 6798039 (-0.23%) cycles in affected programs: 6381699 -> 6366057 (-0.25%) helped: 74 HURT: 0 helped stats (abs) min: 24 max: 1488 x̄: 211.38 x̃: 149 helped stats (rel) min: 0.20% max: 0.44% x̄: 0.26% x̃: 0.25% 95% mean confidence interval for cycles value: -261.68 -161.08 95% mean confidence interval for cycles %-change: -0.28% -0.25% 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.
