This commit enables the I/O vectorization pass that was originally
written for ACO for Intel drivers. We enable it for UBOs, SSBOs, global
memory, and SLM. We only enable vectorization for the scalar back-end
because it vec4 makes certain alignment assumptions.

GAINED: 2
Most of the helped shaders were in the following titles:
- Doom
- Deus Ex: Mankind Divided
- Aztec Ruins
- Shadow of Mordor
- DiRT Showdown
- Tomb Raider (Rise, I think)
Five of the lost programs are SIMD16 shaders we lost from dirt showdown.
The other two are compute shaders in Aztec Ruins which switched from
SIMD8 to SIMD16.
Vulkan pipeline-db stats on ICL:
Instructions in all programs: 296780486 -> 293493363 (-1.1%)
Loops in all programs: 149669 -> 149669 (+0.0%)
Cycles in all programs: 90999206722 -> 88513844563 (-2.7%)
Spills in all programs: 1710217 -> 1730691 (+1.2%)
Fills in all programs: 1931235 -> 1958138 (+1.4%)
By far the most help was in the Tomb Raider games. A couple of Batman
games with DXVK were also helped. In Shadow of the Tomb Raider:
Instructions in all programs: 41614336 -> 39408023 (-5.3%)
Loops in all programs: 32200 -> 32200 (+0.0%)
Cycles in all programs: 1875498485 -> 1667034831 (-11.1%)
Spills in all programs: 196307 -> 214945 (+9.5%)
Fills in all programs: 282736 -> 307113 (+8.6%)
Benchmarks of real games I've done on this patch:
- Rise of the Tomb Raider: +3%
- Shadow of the Tomb Raider: +10%

`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>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
