Vulkan has the concept of separate image and sampler objects in the SPIR-V code whereas GL conflates them into one. nir_lower_samplers contains an assert to verify that sampler operand is not being set on the nir instruction. However when the code comes from spirv_to_nir the sampler operand is always set. GL_arb_gl_spirv explicitly states that OpTypeSampler is not supported so it retains the GL behaviour of not being able to seperate them. Therefore the sampler will always be the same as the texture. This GL version of the lowering code ignores instr->sampler and sets instr->sampler_index to the same value as instr->texture_index. Some other places in the code (such as in nir_print) assume that once the instruction is lowered then both instr->texture and instr->sampler will be NULL, so to keep this behaviour we now set instr->sampler to NULL after ignoring it to fill in instr->sampler_index.

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.
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
