These days, we have two sampler lowering passes. The newer one, gl_nir_lower_samplers_as_deref, is used by radeonsi. It rewrites variables to drop structures out of sampler deref chains, to make life simpler. It then sets var->data.binding for non-bindless sampler and image variables based on the GL uniform storage's opaque index values. The older one converts sampler deref chains (nir_tex_src_texture_deref) to a numerical offset (nir_tex_src_texture_offset). It also stores the constant-valued portion of that number in tex->texture_index, making life really simple for drivers that don't support indirects. It too pokes at GL uniform storage's opaque index values. Logically, we can do the first pass (simplify derefs, set bindings) then the second (turn derefs to offsets, set texture_index). This patch does exactly that, eliminating some redundancy (only one pass has to poke at GL uniform storage), and gaining proper var->data.binding values for drivers using the full lowering.

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

.. 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 `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.
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>`_
