So far we have been using CL_INVOCATION_COUNT to resolve this query but this
is no good with streams, as only stream 0 reaches the clipping stage.
From ARB_transform_feedback3:
"When a generated primitive query for a vertex stream is active, the
primitives-generated count is incremented every time a primitive emitted to
that stream reaches the Discarding Rasterization stage (see Section 3.x)
right before rasterization. This counter is incremented whether or not
transform feedback is active."
Unfortunately, we don't have any registers that provide the number of primitives
written to a specific stream other than the ones that track the number of
primitives written to transform feedback in the SOL stage, so we can't
implement this exactly as specified.
In the past we implemented this feature by activating the SOL unit even if
transform feeback was disabled, but making it so that all buffers were
disabled and it only recorded statistics, which gave us the right semantics
(see 3178d2474a). Unfortunately, this came with
a significant performance impact and had to be reverted.
This new take does not intend to implement the exact semantics required by
the spec, but improves what we have now, since now we return the primitive
count for stream 0 in all cases. With this patch we use
GEN7_SO_PRIM_STORAGE_NEEDED to resolve GL_PRIMITIVES_GENERATED queries
for non-zero streams. This would return the number of primitives written
to transform feedback for each stream instead. Since non-zero streams are
only useful in combination with transform feedback this should not be too
bad, and the only case that I think we would not be supporting would be
the one in which we want to use both GL_PRIMITIVES_GENERATED and
GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN on the same non-zero stream to
detect buffer overflow.
This patch also fixes the following piglit test:
arb_gpu_shader5-xfb-streams-without-invocations
This test uses both GL_PRIMITIVES_GENERATED and
GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN queries on non-zero streams, but it
does never hit the overflow case, so both queries are always expected to return
the same value.

Apparently guardband clipping doesn't work like we thought: objects
entirely outside fthe guardband are trivially rejected, regardless of
their relation to the viewport. Normally, the guardband is larger than
the viewport, so this is not a problem. However, when the viewport is
larger than the guardband, this means that we would discard primitives
which were wholly outside of the guardband, but still visible.
We always program the guardband to 8K x 8K to enforce the restriction
that the screenspace bounding box of a single triangle must be no more
than 8K x 8K. So, if the viewport is larger than that, we need to
disable guardband clipping.

Now that we have the data available, we need to expose it to the
shaders. We can reuse the same vertex element that we use for
gl_VertexID, but we need to back it by an actual vertex buffer.
A hardware restriction requires that vertex attributes coming from a
buffer (STORE_SRC) must come before any other types (i.e. STORE_0).
So, we have to make gl_BaseVertex be the .x component of the vertex
attribute. This means moving gl_VertexID to a different component.
I chose to move gl_VertexID and gl_InstanceID to the .z and .w
components, respectively, to make room for gl_BaseInstance in the .y
component (which would also come from a buffer, and therefore be
STORE_SRC).
