Alyssa Rosenzweig 042adf3cc5 nir/opt_algebraic: optimize signed pow in Control
used in a post-processing shader which goes 896 instrs -> 749 instrs.

In my Control fossil:

   Totals from 2 (0.63% of 319) affected shaders:
   Instrs: 2078 -> 1841 (-11.41%)
   CodeSize: 14540 -> 12800 (-11.97%)

   FSCIB: 1779 -> 1626 (-8.60%)
   Uniforms: 370 -> 372 (+0.54%)

In radv_fossils, there are affected shaders in Dredge.

   Totals from 4 (0.01% of 54019) affected shaders:
   Instrs: 2306 -> 2294 (-0.52%)

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://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ 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
