Brian noticed there was an uninitialized var for the 8-wide case and 128 bit blocks, which made it always crash. Likewise, the 64bit block case had another crash bug due to type mismatch. Color decode (used for all s3tc formats) also had a bogus shuffle for this case, leading to decode artifacts. Fix these all up, which makes the code actually work 8-wide. Note that it's still not used - I've verified it works, and the generated assembly does look quite a bit simpler actually (20-30% less instructions for the s3tc decode part with avx2), however in practice it still seems to be sligthly slower for some unknown reason (tested with openarena) on my haswell box, so for now continue to split things into 4-wide vectors before decoding.

`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. 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.html <https://mesa3d.org/bugs.html>`_).
