This moves some conversions to NIR that may get eliminated, and also distinguishes gl_FragCoord.z/w loads at the shader info level so we don't need to flag uses_src_depth/uses_src_w when only gl_FragCoord.xy get used (as is typical). This reduces thread payload setup on many shaders. Also, interestingly, blorp shaders stop reserving space for z/w despite not putting them in the payload (since PS_EXTRA isn't filled out for z/w).

`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.
