Besides -1.0*x being 1 dword smaller than x^0x80000000, this commit also improves generated code when the application requires that denormals are flushed. Future versions of DXVK will require that 32-bit denormals are flushed. fossil-db (GFX8): Totals from 21021 (14.22% of 147787) affected shaders: SGPRs: 1288960 -> 1288944 (-0.00%); split: -0.01%, +0.01% VGPRs: 792672 -> 792848 (+0.02%); split: -0.01%, +0.03% CodeSize: 62439228 -> 62403552 (-0.06%); split: -0.11%, +0.05% MaxWaves: 136182 -> 136181 (-0.00%); split: +0.00%, -0.00% Instrs: 12230882 -> 12239927 (+0.07%); split: -0.01%, +0.08% fossil-db (GFX10.3): Totals from 20191 (13.80% of 146267) affected shaders: VGPRs: 799992 -> 800032 (+0.01%) CodeSize: 59763656 -> 59715484 (-0.08%); split: -0.12%, +0.03% MaxWaves: 525378 -> 525376 (-0.00%) Instrs: 11511082 -> 11517419 (+0.06%); split: -0.00%, +0.06% fossil-db (GFX8, d3d float controls): Totals from 87160 (58.98% of 147787) affected shaders: SGPRs: 5395072 -> 5408480 (+0.25%); split: -0.06%, +0.31% VGPRs: 3596716 -> 3581592 (-0.42%); split: -0.55%, +0.13% CodeSize: 271347396 -> 266814460 (-1.67%); split: -1.67%, +0.00% MaxWaves: 539669 -> 540400 (+0.14%); split: +0.15%, -0.02% Instrs: 53395194 -> 52257505 (-2.13%); split: -2.13%, +0.00% fossil-db (GFX10.3, d3d float controls): Totals from 82306 (56.27% of 146267) affected shaders: VGPRs: 3572312 -> 3558848 (-0.38%); split: -0.44%, +0.06% CodeSize: 273494748 -> 269648968 (-1.41%); split: -1.41%, +0.00% MaxWaves: 2007156 -> 2009950 (+0.14%); split: +0.15%, -0.01% Instrs: 52251568 -> 51356424 (-1.71%); split: -1.71%, +0.00% Signed-off-by: Rhys Perry <pendingchaos02@gmail.com> Reviewed-by: Daniel Schürmann <daniel@schuermann.dev> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9079> |

`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 `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.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.
