Sviatoslav Peleshko 6b0bfdfa9e nir: Use alu source components count in nir_alu_srcs_negative_equal
When we use source from ALU instruction directly, the default swizzle array
should be populated with the same amount of components as the src has.

Otherwise, if we use nir_ssa_alu_instr_src_components, it can return
the destination components count that is lower than component index
actually used in that source. This can lead to false equality
between 0 (uninitialized) and 0 (.x) in swizzle comparison below.

Fixes: c6ee46a7 ("nir: Add nir_alu_srcs_negative_equal")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/8704

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

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
