The goal is to replace glsl_to_tgsi.cpp and its supporting code (~10k LOC). This code ends up being smaller because NIR has many lowering passes that help it map better to TGSI than GLSL IR does. As a benefit, this brings NIR optimizations to TGSI-only drivers. Many of the softpipe shaders I've looked at end up being significantly shorter. Some potentially relevant changes to TGSI consumers: - All immediates are now UINT typed. This means they're less legible in printouts, but means that they get deduplicated better (no more multiple copies of 0x0!) - Sampler views are not currently declared. - nir_registers don't have their live ranges tracked, so TGSI temp usage may go up with a lot of control flow. - nir_lower_vec_to_mov naively inserts movs instead of trying to coalesce the movs with the generators of the ssa values, sometimes increasing instruction count.

`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 `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. 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.
