Ubo0 is tricky. It exists if there were any uniforms when lower_uniforms_to_ubo was run. If we try to run that ourselves, it might be too late and DCE/remove_dead_variables might've been run, which removed the uniforms and their accesses, without decrementing num_uniforms. So we have no good way of knowing whether to declare ubos from [0, N] or [1, N]. In practice this probably doesn't make much of a difference but the logic is there so ¯\_(ツ)_/¯ If we use the nir option, then dead code isn't run, and num_uniforms is a true indicator of whether ubo0 exists or not. Note that this means we are no longer running this pass for internal shaders that don't come from the GLSL compiler, so various places are updated to query the nir info bit that's set by running this pass.

`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.
