kingstom.chen 5d8b53beea radv/rt: only run move_rt_instructions() for CPS shaders
move_rt_instructions() only makes sense for CPS recursive shaders, where
later rt_trace_ray calls can overwrite the current shader's RT system
values.

Running it on the function-call path can hoist load_hit_attrib_amd
above merged intersection writes, which corrupts any-hit
hitAttributeEXT. Move the pass into the existing CPS-only
non-intersection branch before nir_lower_shader_calls().

Fixes: c5d796c902 ("radv/rt: Use function call structure in NIR lowering")
Closes: #15074

======================================================


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
