Timothy Arceri e19a8fe033 radv: call constant folding before opt algebraic
The pattern of calling opt algebraic first seems to have originated
in i965. The order in OpenGL drivers generally doesn't matter
because the GLSL IR optimisations do constant folding before
opt algebraic.

However in Vulkan drivers calling opt algebraic first can result
in missed constant folding opportunities.

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

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.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.
