Connor Abbott 613eaac7b5 ir3: Initial support for spilling non-shared registers
Support for spilling shared registers to normal registers is still TODO.
There are also several improvements to be made, like rematerialization.

Note, there is one behavior change to register pressure accounting: we
now include half registers in the current full pressure directly in
mergedregs mode, rather than adding the max half pressure to the max
full pressure afterwards, which might result in lower calculated max
pressure in some cases with half registers. This is needed for spilling,
since we need to make sure the total pressure including half registers
is below the maximum at each instruction. Because the entire pass is
rewritten, including the register pressure calculating parts, it didn't
seem worth it to separate out this change.

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 `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.
