Inadvertently, because of a sequence of changes elsewhere, this pass ended up not having any effect: - Before Gfx5 the optimization is not applicable. - On Gfx5-6 it doesn't apply because it sampler operations don't currently use LOAD_PAYLOAD, but write the MOVs directly. Not clear to me whether they ever did. - On Gfx7+ it doesn't apply anymore because now the logical sampler operations are now lowered directly to SENDs, and the is_tex() check would skip them. Since the LOAD_PAYLOAD implementation applies for Gfx7+ only, rework the pass to work again by handling SEND instructions. To make the pass easier, the optimization will happen before opt_split_sends() so only one LOAD_PAYLOAD needs to be cared for. Update the code to accept BAD_FILE sources in addition to zeros, these are added in some cases as padding and effectively are don't care values, so we can assume them zeros.

`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.
