We don't necessarily want to split up MOVs for 64-bit addresses into 2x 32-bit MOVs right away, as this makes things like copy propagating the whole address around harder. We should do this late, once, while still doing other algebraic optimizations earlier. fossil-db results for Alchemist show tiny improvements: Totals: Instrs: 161310502 -> 161310436 (-0.00%); split: -0.00%, +0.00% Cycles: 14370605606 -> 14370605159 (-0.00%); split: -0.00%, +0.00% Totals from 33 (0.01% of 652298) affected shaders: Instrs: 15053 -> 14987 (-0.44%); split: -0.64%, +0.20% Cycles: 196947 -> 196500 (-0.23%); split: -0.25%, +0.02% Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/28286>
`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. 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>`_).
