Switch to register intrinsics, using the helpers. Since our backend copyprop chokes on non-SSA moves, we get better coalescing with this approach, hence the small improvements to instruction count / cycle count in shader-db. Changes to register pressure seem to be noise from iteration order. I'm not too worried. total instructions in shared programs: 1508444 -> 1508193 (-0.02%) instructions in affected programs: 42581 -> 42330 (-0.59%) helped: 482 HURT: 41 Inconclusive result (value mean confidence interval includes 0). total bundles in shared programs: 643023 -> 643136 (0.02%) bundles in affected programs: 16318 -> 16431 (0.69%) helped: 230 HURT: 85 Inconclusive result (value mean confidence interval includes 0). total quadwords in shared programs: 1125992 -> 1125600 (-0.03%) quadwords in affected programs: 125366 -> 124974 (-0.31%) helped: 507 HURT: 351 Quadwords are helped. total registers in shared programs: 90632 -> 90554 (-0.09%) registers in affected programs: 669 -> 591 (-11.66%) helped: 114 HURT: 31 Registers are helped. total threads in shared programs: 55607 -> 55600 (-0.01%) threads in affected programs: 20 -> 13 (-35.00%) helped: 1 HURT: 7 Inconclusive result (value mean confidence interval includes 0). total spills in shared programs: 1371 -> 1437 (4.81%) spills in affected programs: 44 -> 110 (150.00%) helped: 0 HURT: 2 total fills in shared programs: 5133 -> 5273 (2.73%) fills in affected programs: 84 -> 224 (166.67%) helped: 0 HURT: 2 Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Reviewed-by: Faith Ekstrand <faith.ekstrand@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/23089>

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.
