While using SPIR-V shaders (ARB_gl_spirv), layout data is not implicit
to a specific value (std140, std430, etc) but explicitly included on
the type (explicit values for offset, stride and row_major).
So this method is equivalent to the existing std140_size and
std430_size, but using such explicit values.
Note that the value returned by this method is only valid if such data
is set, so when dealing with SPIR-V shaders.
v2: (all changes suggested by Jason Ekstrand)
* Iterate through all struct members, instead of assume that fields
are ordered by offset
* Use else if
* Take into account the case that explicit_stride > elem_size, to
fine graine the final size on arrays and matrices
* Handle different bit-sizes in general, not just 32 and 64.
v3: (change suggested by Caio Marcelo de Oliveira Filho)
* fix up explicit_size() to consider interface types

`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.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 <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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses email mailing-lists for patches submission, review and discussions.
