Rob Clark b1465c382b freedreno/ir3/ra: assign vreg names to all array elements
We shouldn't divide-by-two for half-reg arrays.  We set the proper node
interference class, based on `arr->half`.

Fixes a RA fail with 16b arrays:

  src/freedreno/ir3/ir3_ra.c:633: name_to_array: Assertion `!"invalid array name"' failed.

Caused by use/def iterators returning `arr->length` vreg namess, but
only assigning the array half that many names.

Also, since we are assigning unique vreg names to each array element,
there is no need to try and convert from half-reg to it's conflicting
full reg when pre-coloring the array elements.  Getting us closer to
having half-arrays work sanely with split-register-file (a5xx and
earlier).

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


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


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
