Lower texture projection in ppir using nir_lower_tex and nir_lower_tex. This will insert a mul with the coordinate division before the load varying. Even though the lima pp supports projection in the load varying instruction while loading the coordinates (from a register or a varying), it requires that both the coordinates and projector be components in a single register. nir currently handles them in separate ssa, and attempting to merge them manually may end up in worse code than just doing the coordinate division manually. So for now let's just lower the projection to add support for it in lima. In the future, an optimization pass may be implemented in lima to ensure that both coords and projector come in the same register, then this lowering may be disabled and in this case lima may use the built-in projection and save the mul instruction from lowering.

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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.
