On scalar ISAs, nir_lower_io_to_scalar_early enables significant optimizations. However, on vector ISAs, it is counterproductive and impedes optimal codegen. This patch only calls nir_lower_io_to_scalar_early for scalar ISAs. It appears that at present there are no upstreamed drivers using Gallium, NIR, and a vector ISA, so for existing code, this should be a no-op. However, this patch is necessary for the upcoming Panfrost (Midgard) and Lima (Utgard) compilers, which are vector. With this patch, Panfrost is able to consume NIR directly, rather than TGSI with the TGSI->NIR conversion. For how this affects Lima, see https://www.mail-archive.com/mesa-dev@lists.freedesktop.org/msg189216.html Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Reviewed-by: Timothy Arceri <tarceri@itsqueeze.com> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com> |

$ 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
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_
