For example, dwordx3->dwordx4 or ubyte3->dwordx2. Global loads don't have the bounds checking that buffer loads have that makes this safe. The alignment checks are added to global_load_callback() in case byte_align_loads=false, align=1 and bytes_needed=3. Without them, the callback will create a dword load. fossil-db (Sienna Cichlid): Totals from 267 (0.20% of 134621) affected shaders: CodeSize: 1603352 -> 1606568 (+0.20%) Instrs: 294946 -> 295482 (+0.18%); split: -0.00%, +0.18% Latency: 2997003 -> 2997052 (+0.00%); split: -0.02%, +0.02% InvThroughput: 526645 -> 526659 (+0.00%) SClause: 9179 -> 9185 (+0.07%); split: -0.02%, +0.09% Copies: 25363 -> 25375 (+0.05%); split: -0.08%, +0.13% Branches: 8298 -> 8299 (+0.01%) fossil-db (Polaris10): Totals from 267 (0.20% of 135668) affected shaders: CodeSize: 1636672 -> 1638756 (+0.13%); split: -0.00%, +0.13% Instrs: 308484 -> 308733 (+0.08%); split: -0.01%, +0.09% Latency: 3446045 -> 3446904 (+0.02%); split: -0.00%, +0.03% InvThroughput: 1206722 -> 1206828 (+0.01%); split: -0.00%, +0.01% SClause: 9308 -> 9311 (+0.03%); split: -0.08%, +0.11% Copies: 36933 -> 36921 (-0.03%); split: -0.08%, +0.05% fossil-db (Pitcairn): Totals from 275 (0.20% of 135668) affected shaders: SGPRs: 17616 -> 17520 (-0.54%); split: -0.64%, +0.09% VGPRs: 15428 -> 15540 (+0.73%); split: -0.23%, +0.96% CodeSize: 1885792 -> 1929120 (+2.30%); split: -0.00%, +2.30% MaxWaves: 1284 -> 1285 (+0.08%) Instrs: 368963 -> 376095 (+1.93%); split: -0.00%, +1.94% Latency: 5122922 -> 5168398 (+0.89%); split: -0.01%, +0.90% InvThroughput: 2562866 -> 2604279 (+1.62%) VClause: 9268 -> 9296 (+0.30%); split: -0.13%, +0.43% SClause: 10702 -> 10705 (+0.03%); split: -0.05%, +0.07% Copies: 48620 -> 50629 (+4.13%); split: -0.08%, +4.21% Signed-off-by: Rhys Perry <pendingchaos02@gmail.com> Reviewed-by: Timur Kristóf <timur.kristof@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14124>
`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 `OFTC's #dri-devel <irc://irc.oftc.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.
