[Mesa-dev] [PATCH 00/11] Initial gl_spirv support in Mesa and i965

[Alejandro Piñeiro]

Hi,

This is the 5rd version of the series adding initial support for
ARB_gl_spirv. Although the development branch is bigger (more that 80
patches), as mentioned, we prefer to send small, self-contained
series, to make the review process easier.

This series is mostly equal to v4 except:

 * New version of patch "nir/spirv: add gl_spirv_validation method"
   after Jason feedback.

 * New patch: "spirv: add vtn_builder_create". On v4 this code was
   part of the previous patch. This changes the patches numbering.

 * Rebased against today master. There were minor rebase changes. So
   minor that are not mentioned on the commit itself.

As with v4, we are splitting the series, so after this series we will
send one for ARB_spirv_extensions.

Notice also that some patches from version 2 were merged in
master. These were already reviewed favorably and were fairly
independent from the rest of the series.

There are already 5 patches in this new series with a Reviewed-by tag
that we didn't merge yet because we consider they should go in with
the rest of the series. The patches missing review are 01, 02, 03, 04,
05 and 08.
