Previously the code was taking any location decoration on the block
and using that to calculate the member locations for all of the
members. I think this was assuming that there would only be one
location decoration for the entire block. According to the Vulkan spec
it is possible to add location decorations to individual members:
“If the structure type is a Block but without a Location, then each
of its members must have a Location decoration. If it is a Block
with a Location decoration, then its members are assigned
consecutive locations in declaration order, starting from the
first member which is initially the Block. Any member with its own
Location decoration is assigned that location. Each remaining
member is assigned the location after the immediately preceding
member in declaration order.”
This patch makes it instead keep track of which members have been
assigned an explicit location. It also has a space to store the
location for the struct as a whole. Once all the decorations have been
processed it iterates over each member to fill in the missing
locations using the rules described above.
So, this commit is needed to get working a case like this, on both
Vulkan and OpenGL using SPIR-V (ARB_gl_spirv):
out block {
layout(location = 2) vec4 c;
layout(location = 3) vec4 d;
layout(location = 0) vec4 a;
layout(location = 1) vec4 b;
} name;

`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 status ------------ Travis: .. image:: https://travis-ci.org/mesa3d/mesa.svg?branch=master :target: https://travis-ci.org/mesa3d/mesa Appveyor: .. image:: https://img.shields.io/appveyor/ci/mesa3d/mesa.svg :target: https://ci.appveyor.com/project/mesa3d/mesa Coverity: .. image:: https://scan.coverity.com/projects/139/badge.svg?flat=1 :target: https://scan.coverity.com/projects/mesa 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.
