Ian Romanick 80a5d158ae brw/copy: Don't copy propagate through smaller entry dest size 
Copy propagation would incorrectly occur in this code

    mov(16) v4+2.0:UW, u0<0>:UW NoMask
    ...
    mov(8) v6+2.0:UD, v4+2.0:UD NoMask group0

to create

    mov(16) v4+2.0:UW, u0<0>:UW NoMask
    ...
    mov(8) v6+2.0:UD, u0<0>:UD NoMask group0

This has different behavior. I think I just made a mistake when I
changed this condition in e3f502e007.

It seems like this condition could be relaxed to cover cases like (note
the change of destination stride)

    mov(16) v4+2.0<2>:UW, u0<0>:UW NoMask
    ...
    mov(8) v6+2.0:UD, v4+2.0:UD NoMask group0

I'm not sure it's worth it.

No shader-db or fossil-db changes on any Intel platform. Even the code
for the test case mentioned in the original commit did not change.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library
======================================================


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://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.
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
