Job Noorman 9b6bca52d5 ir3: optimize alias register allocation by reusing GPRs
Allocate alias registers for an alias group while trying to minimize the
number of needed aliases. That is, if the allocated GPRs for the group
are (partially) consecutive, only allocate aliases to fill-in the gaps.
For example:
   sam ..., @{r1.x, r5.z, r1.z}, ...
only needs a single alias:
   alias.tex.b32.0 r1.y, r5.z
   sam ..., r1.x, ...

Also, try to reuse allocations of previous groups. For example, this is
relatively common:
   sam ..., @{r2.z, 0}, @{0}
Reusing the allocation of the first group for the second one gives this:
   alias.tex.b32.0 r2.w, 0
   sam ..., r2.z, r2.w

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://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ 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.
