    The language version a shader is written to is specified by

        #version number profile opt

    where number must be a version of the language, following the same
    convention as __VERSION__ above.

The same section also says:

    __VERSION__ will substitute a decimal integer reflecting the version
    number of the OpenGL shading language.

Use a separate flag to track whether or not the #version line has been
encountered.  Any possible sentinel (0 is currently used) could be
specified in a #version directive.  This would lead to trying to
(internally) redefine __VERSION__.  Since there is no parser location
for this addition, NULL is passed.  This eventually results in a NULL
dereference and a segfault.

Attempts to use -1 as the sentinel would also fail if '#version

Revert "wayland: Block for the frame callback in get_back_bo not dri2_swap_buffers"

This reverts commit 25cc889004aad6d1cab9edd76db898658e347b97, though
since the code has changed, it was applied manually.

The intent of moving blocking from SwapBuffers to get_back_bo, was to
avoid unnecessary triple-buffering by ensuring that the compositor had
fully processed the previous frame before we started rendering. This
means that the only time we would have to resort to triple-buffering
would be when the buffer is directly scanned out, thus saving an extra
buffer for composition anyway.

The 'repaint window' changes introduced in Weston since then, however,
have narrowed the window of time between the frame event being sent and
the repaint loop needing to conclude, to 7ms by default, in order to
reduce latency. This means however that blocking in get_back_bo gives a
maximum of 7ms for the entire GL submission to begin and complete.

Not only this, but if a client is using buffer_age to avoid full
repaints, the buffer-age request will stall in get_back_bo until the
frame callback completes, meaning that the client cannot even calculate
the repaint area before the 7ms window.

The combination of the two meant that WebKit-GTK+ was failing to
achieve full framerate on a Minnowboard, due to spending a great deal of
its time attempting to query the age of the next buffer before redraw.

Revert to the previous behaviour of allowing rendering to begin but
delaying SwapBuffers, unless and until we can find a more gentle
behaviour.

glsl: validate output blocks against input blocks

Until now were validating in/out blocks by listing the inputs in the
consumer stage and then, for each output of the producer, we checked that
it was a match if it was consumed. This method does not catch the case
where the consumer has an input that is not present as an output in the
producer stage, because it only generates link errors for outputs present
in the producer stage that don't match the inputs in the consumer stage.
The current method does catch the case were an output from the producer
stage is not consumed, which is irrelevant and is ignored.

By reversing the way we do this, we can detect this situation, so this
patch lists the outputs of the producer stage and then validates inputs
of the consumer stage against them. If we see an input in the consumer
for which there is no associated output in the producer, we produce a
link error.

The only exception to this is the special built-in input block gl_in[],
since this is implicitly generated for geometry and tessellation stages,
but we don't generate it if the producer stage does not write to any of
the pre-defined outputs (for example, if the vertex shader does not write
to gl_Position, etc). Since writing to these is not mandatory, do not
produce a link error in that case. There is a CTS tessellation test
(GL45-CTS.tessellation_shader.program_object_properties) that has an
empty vertex shader (so it does not produce gl_in[]) and would fail to
link if we don't do this.

the shader, despite QIR and QPU scheduling both trying to delay scoreboard
locking for as long as possible.

The problem was that when trying to pair up QPU instructions, at some
point the passthrough tlb_z would be the last one available and it would
get paired, even if the other half would open up other instructions to be
scheduled and we could have paired tlb_z with something later in the
program.  Also, since passthrough z is just a mov, it pairs up really
easily.

The proper fix would probably be to flip the order of scheduling
instructions so we went from bottom to top (also relevant for branch delay
slot scheduling).

However, we can do a quick fix here to just not schedule a TLB lock until

I have diagnosed the failures, but I'm not sure whether we or the
tests are wrong.  After optimizations are applied, all of the tests
are of the form:

    buffer X {
        float f;
    } x;

    void main()
    {
        x.f = x.f;
    }

The test then queries that x is referenced by that shader stage.  We
eliminate the assignment of x.f to itself, and that removes the last
reference to x.  We report that x is not referenced, and the test fails.
I do not know whether or not we are allowed to eliminate that assignment
of x.f to itself.

After discussions with the OpenGL ES group in Khronos, we believe that
Mesa's behavior is correct.  I will provide patches to the CTS tests
to Khronos.

anv: Move relocation handling from EndCommandBuffer to QueueSubmit

Ever since the early days of the Vulkan driver, we've been setting up the
lists of relocations at EndCommandBuffer time.  The idea behind this was to
move some of the CPU load out of QueueSubmit which the client is required
to lock around and into command buffer building which could be done in
parallel.  Then QueueSubmit basically just becomes a bunch of execbuf2
calls.

Technically, this works.  However, when you start to do more in QueueSubmit
than just execbuf2, you start to run into problems.  In particular, if a
block pool is resized between EndCommandBuffer and QueueSubmit, the list of
anv_bo's and the execbuf2 object list can get out of sync.  This can cause
problems if, for instance, you wanted to do relocations in userspace.
