There were tests related to propagating conditional modifiers from a MOV to an instruction with a .SAT modifier for a very long time, but they were #if'ed out. There are restrictions later in the function that limit the kinds of MOV instructions that can propagate. This avoids the dangers of type-converting MOVs that may generate flags in different ways. v2: Update the added comment to look more like the existing comment. That makes the small differences between the two cases more obvious. Noticed by Marcin. All Intel platforms had similar results. (Ice Lake shown) total instructions in shared programs: 19827127 -> 19826924 (<.01%) instructions in affected programs: 62024 -> 61821 (-0.33%) helped: 201 HURT: 0 helped stats (abs) min: 1 max: 2 x̄: 1.01 x̃: 1 helped stats (rel) min: 0.13% max: 0.60% x̄: 0.35% x̃: 0.36% 95% mean confidence interval for instructions value: -1.02 -1.00 95% mean confidence interval for instructions %-change: -0.36% -0.34% Instructions are helped. total cycles in shared programs: 954655879 -> 954655356 (<.01%) cycles in affected programs: 1212877 -> 1212354 (-0.04%) helped: 155 HURT: 6 helped stats (abs) min: 1 max: 6 x̄: 3.65 x̃: 4 helped stats (rel) min: <.01% max: 0.17% x̄: 0.07% x̃: 0.07% HURT stats (abs) min: 2 max: 12 x̄: 7.00 x̃: 8 HURT stats (rel) min: 0.04% max: 0.23% x̄: 0.14% x̃: 0.15% 95% mean confidence interval for cycles value: -3.60 -2.90 95% mean confidence interval for cycles %-change: -0.07% -0.05% Cycles are helped.

`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.
