Iago Toral Quiroga f512965b0b mesa/st: make sure we remove dead IO variables before handing NIR to backends 
Commit "1c2bf82d24a glsl: disable lower_fragdata_array() for NIR drivers"
disabled the GLSL IR lowering that turned gl_FragData from an array into a
collection of scalar outputs under the assumption that this was already being
handled properly elsewhere, however there are some corner cases where NIR
would fail to do this, leaving gl_FragData[] as an array variable. This can
break backends that assume that all their outputs will be scalar and use the
variable definitions from the shader to do their output setup, such as the
case of V3D.

At least one corner case was found in some Portal shaders from shader-db, where
NIR would optimize out the full body of a fragment shader. In this scenario,
the empty shader would keep the original array definition of gl_FragData[],
causing the backend to assert.

We need to do this late enough for it to be effective, since doing it in
st_nir_preprocess does not fix the original problem.

Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/2091
Fixes: 1c2bf82d ("glsl: disable lower_fragdata_array() for NIR drivers")

======================================================


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
-------

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>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
