This optimizes v_add(c, s_lshl(a, b)) to v_mad_u32_u24(a, 1<<b, c) if 'b' is a constant (less than or equal to 6 to avoid creating literals) and 'a' known to be a 16-bit or a 24-bit value. On GFX9+, this is already optimized to v_lshl_add_u32. fossils-db (Polaris10): Totals from 1916 (1.36% of 140385) affected shaders: SGPRs: 88322 -> 87780 (-0.61%); split: -0.66%, +0.05% CodeSize: 7852668 -> 7851800 (-0.01%); split: -0.01%, +0.00% Instrs: 1533965 -> 1530459 (-0.23%); split: -0.23%, +0.00% Cycles: 57001852 -> 56983244 (-0.03%); split: -0.03%, +0.00% VMEM: 372561 -> 371733 (-0.22%); split: +0.03%, -0.25% SMEM: 108859 -> 103711 (-4.73%); split: +0.23%, -4.96% VClause: 37231 -> 37204 (-0.07%) SClause: 58116 -> 58086 (-0.05%); split: -0.06%, +0.01% Copies: 199953 -> 199931 (-0.01%); split: -0.03%, +0.02% Branches: 63478 -> 63477 (-0.00%) PreSGPRs: 61818 -> 61816 (-0.00%) Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Rhys Perry <pendingchaos02@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/7673> |

`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.
