This delays the waitcnt for has_attr_ring_wait_bug by a few instructions. fossil-db (gfx1201): Totals from 9 (0.00% of 208640) affected shaders: Instrs: 19352 -> 19506 (+0.80%) CodeSize: 101180 -> 101716 (+0.53%) Latency: 660221 -> 678782 (+2.81%); split: -0.00%, +2.81% InvThroughput: 95106 -> 97398 (+2.41%) fossil-db (navi33): Totals from 58834 (28.20% of 208626) affected shaders: Instrs: 22424304 -> 22424571 (+0.00%) CodeSize: 110198112 -> 110199184 (+0.00%) Latency: 115894319 -> 126491124 (+9.14%); split: -0.00%, +9.14% InvThroughput: 19424631 -> 19754358 (+1.70%); split: -0.00%, +1.70% I don't think the stats are very accurate. This seems to often move the s_waitcnt down into a divergent branch, but the wait still happens later if the branch isn't taken, so the wait is counted twice.

`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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
