On v11+, all small integers instruction variants are gone, however we can now use widen on src0 just fine. That mean we can get ride of mid conversion by relying on swizzle instead while respecting signess of the inner instruction. This helps a little bit on clpeak with panvk+clvk, shader-db is also happy: Totals: Instrs: 109541 -> 109354 (-0.17%) CodeSize: 1110528 -> 1108864 (-0.15%) Estimated normalized CVT cycles: 667.609375 -> 664.5625 (-0.46%) Totals from 17 (2.12% of 803) affected shaders: Instrs: 13637 -> 13450 (-1.37%) CodeSize: 112256 -> 110592 (-1.48%) Estimated normalized CVT cycles: 100.203125 -> 97.15625 (-3.04%) Signed-off-by: Mary Guillemard <mary.guillemard@collabora.com> Reviewed-by: Eric R.

`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>`_).
