Zan Dobersek b8cc891e6e ir3: allow asm roundtrip testing of compiled shader variants
The `asmroundtrip` IR3_SHADER_DEBUG option enables roundtrip testing of
ir3 asm facilities by generating disassembly for each compiled shader
variant, parsing that disassembly back into ir3 and assembling back into
binary, with the expectation that the initial binary and the post-roundtrip
binary are identical.

This should give some guarantee that any shader that ir3 can produce can
also be constructed through assembly and fed back into ir3.

When enabled, each shader variant has a parallel roundtrip variant created.
At the moment this variant is discarded after validation, but it could
replace the initial variant in the future to also test behavior of such
roundtrip-generated binary and accompanying metadata.

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
