[Mesa-dev] [PATCH v4 00/10] Initial gl_spirv support in Mesa and i965

[Alejandro Piñeiro]

Hi,

This is the 4rd version of the series adding initial support for
ARB_gl_spirv. This series is equal to v3 we sent one month ago [1],
but rebased against today master.

As with v3, 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 still 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
and 07.

As usual, a git tree containing this series can be found at
<https://github.com/Igalia/mesa/tree/arb_gl_spirv-series1-v4> and the
larger, work-in-progress, often force-pushed series at
<https://github.com/Igalia/mesa/tree/wip/igalia/arb_gl_spirv>.

Thanks for reviewing
