Jason Ekstrand 25c180b509 intel: Don't cross DWORD boundaries with byte scratch load/store
The back-end swizzles dwords so that our indirect scratch messages match
the memory layout of spill/fill messages for better cache coherency.
The swizzle happens at a DWORD granularity.  If a read or write crosses
a DWORD boundary, the first bit will get correctly swizzled but whatever
piece lands in the next dword will not because the scatter instructions
assume sequential addresses for all bytes.  For DWORD writes, this is
handled naturally as part of scalarizing.  For smaller writes, we need
to be sure that a single write never escapes a dword.

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 `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
