...Rather than reserving the union of the registers live-out of the predecessors. This avoids reserving registers that are killed along a control flow edge (where the predecessor has another successor that does use the register). glmark2 subset of shaderdb: total instructions in shared programs: 6442 -> 6440 (-0.03%) instructions in affected programs: 42 -> 40 (-4.76%) helped: 1 HURT: 0 total bytes in shared programs: 42186 -> 42174 (-0.03%) bytes in affected programs: 270 -> 258 (-4.44%) helped: 1 HURT: 0 total halfregs in shared programs: 1769 -> 1757 (-0.68%) halfregs in affected programs: 75 -> 63 (-16.00%) helped: 3 HURT: 0 helped stats (abs) min: 4.0 max: 4.0 x̄: 4.00 x̃: 4 helped stats (rel) min: 16.00% max: 16.00% x̄: 16.00% x̃: 16.00% Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/18804> |

`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>`_). 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.
