I don't know why the float_saturate_l_mov test was #if'ed out, but it
passes... so this commit enables it.
No shader-db or fossil-db changes.
In a previous iteration of this MR, this commit helped ~200 shaders in
shader-db. Now all of those same shaders are helped by "intel/fs: cmod
propagate from MOV with any condition". All of these shaders come from
Mad Max. After initial translation from NIR to assembly, these shader
contain patterns like:
mul(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
...
mov.sat(8) g90<1>F g90<8,8,1>F
...
cmp.nz.f0(8) null<1>F g90<8,8,1>F 0 /* 0F */
An initial pass of cmod propagation converts this to
mul(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
...
mov.sat.XX.f0(8) g90<1>F g90<8,8,1>F
Without this commit, XX is G. With this commit, XX is NZ. Saturate
propagation moves the saturate:
mul.sat(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
...
mov.XX.f0(8) g90<1>F g90<8,8,1>F
Without this commit (but with "intel/fs: cmod propagate from MOV with
any condition"), the G gets propagated:
mul.sat.g.f0(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
With this commit (with or without "intel/fs: cmod propagate from MOV
with any condition"), the NZ gets propagated:
mul.sat.nz.f0(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */

`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.
