In presence of NaNs, "!(flt(a, b) && flt(c, d))" is NOT EQUAL to "fge(a, b) || fge(c, d)". These optimizations are unsafe for apps that rely on NaN behaviour. pipeline-db (GFX9/LLVM): Totals from affected shaders: SGPRS: 3176 -> 3136 (-1.26 %) VGPRS: 2188 -> 2144 (-2.01 %) Spilled SGPRs: 227 -> 169 (-25.55 %) Code Size: 150572 -> 151800 (0.82 %) bytes Max Waves: 307 -> 310 (0.98 %) pipeline-db (GFX9/ACO): Totals from affected shaders: SGPRS: 18744 -> 18744 (0.00 %) VGPRS: 15576 -> 15580 (0.03 %) Spilled SGPRs: 164 -> 164 (0.00 %) Code Size: 1573012 -> 1576492 (0.22 %) bytes Max Waves: 1534 -> 1532 (-0.13 %) Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/2127 Fixes: |

`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.
