Otherwise LLVM does not see the pointers as allowing speculative loads. The pipeline-db results are pretty wild, but mostly what is to be expected from allowing more code movement in LLVM: Totals from affected shaders: SGPRS: 157728 -> 168336 (6.73 %) VGPRS: 158628 -> 158664 (0.02 %) Spilled SGPRs: 10845 -> 24753 (128.24 %) Spilled VGPRs: 13 -> 13 (0.00 %) Private memory VGPRs: 0 -> 0 (0.00 %) Scratch size: 8 -> 8 (0.00 %) dwords per thread Code Size: 17189180 -> 17313712 (0.72 %) bytes LDS: 204 -> 204 (0.00 %) blocks Max Waves: 5700 -> 5687 (-0.23 %) Wait states: 0 -> 0 (0.00 %) This gives some boosts for shaders we can move a descriptor load outside a loop.

`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.
