Move the calculation to nir_lower_vars_to_explicit_types(). This consolidates the check of shader_info::shared_memory_explicit_layout in a single place instead of in all drivers. This is motivated by SPV_KHR_untyped_pointers. Before that extension we had essentially two modes for shared memory variables - No layout decorations in the SPIR-V, and both internal layout and driver location was _given by the driver_. - Explicitly laid out, i.e. they are blocks, and decorated with Aliased. Because they all alias, we could assign them driver location directly to the start of the shared memory. With the untyped pointers extension, there's a third option, to be added by a later commit - Explicitly laid out, i.e. they are blocks, and NOT decorated with Aliased. Driver location is _given by the driver_. Blocks with and without Aliased can be mixed. The driver location of multiple blocks that don't alias depend on alignment that is driver-specific, which we can more easily do from the nir_lower_vars_to_explicit_types() that already has access to a function to obtain such value.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== 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 mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
