Faith Ekstrand ddad2d3af1 nir/trivialize: Trivialize cross-block loads
In order for a register load to be trivial, it cannot be used in any
block other than the one in which it is loaded.  We're not currently
explicitly doing anything to ensure this invariant holds.  It may be
that it holds regardless but I couldn't find any documented reason why
it should so let's explicitly handle that case.  Worst case, the newly
added code does nothing.

Fixes: d313eba94e ("nir: Add pass for trivializing register access")

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
-------

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
