Allow inputs/outputs to be vecN (ie. whatever their actual size is), and use split to get scalar components of inputs, and collect to gather up scalar components of outputs. The main motivation is to simplify RA, by only having to consider split/ collect to figure out where values need to land in consecutive scalar registers, rather than having to also deal with left/right neighbors. Because of varying packing, and the resulting fractional location (location_frac), to implement load_input/store_output, it is still convenient to have a table of scalar inputs/outputs. We move this to the compile ctx (since it is only needed for nir->ir3). Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Kristian H.

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.
