The application supplied [start, end] range is merely a conservative
hint of the ranges of index values inside the index buffer. There is no
requirement that all vertices in the range [start, end] be referenced.
Passing an 'end' value larger than the maximum legal index is perfectly
acceptible; applications can legally pass 0xffffffff when they don't
have a tighter bound readily available.
Thus, the warning doesn't indicate a correctness issue; it could only
indicate a performance issue. However, it does not even do that.
glDrawRangeElements is designed to optimize non-VBO vertex data uploads
by providing an upper bound on the size of buffers a driver would need
to allocate. With VBOs, the data is already in an uploaded buffer, so
the range doesn't help.
The clincher is: we only know _MaxElement for VBOs. For user-space
arrays, we just set it to 2,000,000,000 (see mesa/main/varray.h:63.)
So we can only check this in the case where it is not useful.
Many applications, including the Unigine demos, currently trigger this
warning, which suggests the applications are buggy when they're actually
fine. Eliminating the warning should confuse users less while not
actually losing any benefit to application developers.

Avoid unrollong loops that are either nested loops or
where the loop body times the unroll count is huge.
The change is far from being perfect but it extends the
loop unrolling decision heuristic by some additional
safeguard. In particular this cuts down compilation of
a shader precomputing atmospheric scattering integral
tables containing two nesting levels in a loop from
something way beyond some minutes (I never waited for
it to finish) to some fractions of a second.

From 965 B-spec http://intellinuxgraphics.org/VOL_1_graphics_core.pdf at
page 135:
All of the LOD=0 q-planes are stacked vertically, then below that,
the LOD=1 qplanes are stacked two-wide, then the LOD=2 qplanes are
stacked four-wide below that, and so on.
Thus we should always inrease pack_x_nr, which results to the pitch of LODn
may greater than the pitch of LOD0. So we should refactor mt->total_width
when needed.

There's a serious trap for drivers: RenderTexture() does not indicate
that the texture is currently bound to the draw buffer, despite
FinishRenderTexture() signaling that the texture is just now being
unbound from the draw buffer.
We were acting as if RenderTexture() *was* the start of rendering and
that we could make texturing incoherent with the current contents of
the renderbuffer. This caused intel oglconform sRGB
Mipmap.1D_textures to fail, because we got a call to TexImage() and
thus RenderTexture() on a texture bound to a framebuffer that wasn't
the draw buffer, so we skipped validating the new image into the
texture object used for rendering.
We can't (easily) make RenderTexture() indicate the start of drawing,
because both our driver and gallium are using it as the moment to set
up the renderbuffer wrapper used for things like MapRenderbuffer().
Instead, postpone the setup of the workaround render target miptree
until update_renderbuffer time, so that we no longer need to skip
validation of miptrees used as render targets. As a bonus, this
should make GL_NV_texture_barrier possible.
(This also fixes a regression in the gen4 small-mipmap rendering since
3b38b33c16, which switched
set_draw_offset from image->mt to irb->mt but didn't move the irb->mt
replacement up before set_draw_offset).

NOTE: This is a candidate for the 8.0 branch.
From the GLSL 1.30 spec:
The discard keyword is only allowed within fragment shaders. It
can be used within a fragment shader to abandon the operation on
the current fragment. This keyword causes the fragment to be
discarded and no updates to any buffers will occur. Control flow
exits the shader, and subsequent implicit or explicit derivatives
are undefined when this control flow is non-uniform (meaning
different fragments within the primitive take different control
paths).

A little analysis shows that the worst-case value for "nr" is 17:
- base_mrf = 2 ... 2
- header present (say gen == 5) ... 4
- aa_dest_stencil_reg (stencil test) ... 5
- SIMD16 mode: += 4 * reg_width ... 13
- source_depth_to_render_target ... 15
- dest_depth_reg ... 17
This resulted in us setting base_mrf to 2 and mlen to 15. In other
words, we'd try to use m2..m16. But m16 doesn't exist pre-Gen6. Also,
the instruction scheduler data structures use arrays of size 16, so this
would cause us to access them out of bounds.
While the debugger system routine may need m0 and m1, we don't use it
today, so the simplest solution is just to move base_mrf back to 1.
That way, our worst case message fits in m1..m15, which is legal.
An alternative would be to fail on SIMD16 in this case, but that seems
a bit unfortunate if there's no real need to reserve m0 and m1.

When SPRITE_POINT_ENABLE bit is set, the texture coord would be
replaced, and this is only needed when we called something like
glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE).
And more, we currently handle varying inputs as texture coord,
we would be careful when setting this bit and set it just when
needed, or you will find the value of varying input is not right
and changed.
Thus we do set SPRITE_POINT_ENABLE bit only when all enabled tex
coord units need do CoordReplace. Or fallback is needed to make
sure the rendering is right.
With handling the bit setup at i915_update_sprite_point_enable(),
we don't need the relative code at i915Enable then.
