Alejandro Piñeiro e594e4cefd v3d: adds an extra MOV for any sig.ld*
Specifically when we are in non-uniform control flow, as we would need
to set the condition for the last instruction. If (for example) a
image atomic load stores directly their value on a NIR register,
last_inst would be a nop, and would fail when set the condition.

Fixes piglit test:
spec/glsl-es-3.10/execution/cs-ssbo-atomic-if-else-2.shader_test

Fixes: 6281f26f06 ("v3d: Add support for shader_image_load_store.")

v2: (Changes suggested by Eric Anholt)
   * Cover all sig.ld* signals, not just ldunif and ldtmu, as all of
     them have the same restriction.
   * Update comment explaining why we add a MOV in that case
   * Tweak commit message.

v3:
   * Drop extra set of parens (Eric)
   * Add missing ld signal to is_ld_signal to fix shader-db regression.

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.html
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.html <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 `Freenode's #dri-devel
<irc://chat.freenode.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.
