00a182d66e mesa: fix issues with texture border and array textures
For a 1D texture array, the border only applies to the width.  For a 2D
texture array the border applies to the width and height but not the depth.
Sucha cases were  not handled correctly in _mesa_init_teximage_fields().

Note: This is a candidate for stable branches

d342246e2b i965: Make the dummy fragment shader work in SIMD16 mode.
If you're resorting to the dummy shader, you've probably already turned
off SIMD16 mode.  But if you didn't, it would die in a fire.

We could either fail to compile in SIMD16 mode...or just fix it.

eb2eb97baf vbo: Rework checking of 'end' against _MaxElement.
This failed to take basevertex into account:

If basevertex < 0:
   (end + basevertex) might actually be in-bounds while 'end' is not.
   We would have clamped in this case when we probably shouldn't.
   This could break application drawing.

If basevertex > 0:
   'end' might be in-bounds while (end + basevertex) might not.
   We would have failed to clamp in this place.  There's a comment
   indicating the TNL module depends on max_index being in-bounds;
   if so, it would likely break horribly.

Rather than trying to clamp correctly in the face of basevertex, simply
delete the clamping code and indicate that we don't have a valid range.
This causes _tnl_vbo_draw_prims to use vbo_get_minmax_indices() to
compute the actual bounds, which is much safer.

7032a56c85 vbo: Ignore invalid element ranges which are outside VBO bounds.
Some applications, such as Regnum Online, appear to pass invalid
start/end values to glDrawRangeElements.  In particular, the 'start'
index sometimes exceeds the maximum array element.  This is clearly
invalid behavior, and although the spec isn't clear, seems to result
in undefined, implementation-specific behavior.

This patch takes the conservative approach and simply ignores the range,
while issuing a warning indicating that the application is broken and
should be fixed.

NOTE: This is a candidate for release branches.

3aaf3c85e4 vbo: Remove pedantic warning about 'end' beind out of bounds.
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.

8a7cb5d21c glsl: Avoid excessive loop unrolling.
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.

fa68a8bae3 i965: fix wrong cube/3D texture layout
Fix wrong cube/3D texture layout for the tailing levels whose width or

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.

This would fix the following webgl test case on all gen4 platforms:

93e94cbb48 intel: Fix rendering from textures after RenderTexture().
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).

     The discard keyword is only allowed within fragment shaders. It
     can be used within a fragment shader to abandon the operation on

     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).

C still treats array arguments exactly like pointer arguments.
By sheer coincidence, this still worked fine on 64-bit
machines where 2 * sizeof(float) == sizeof(void*), but not
on 32-bit.

Noticed by clang:

text.c:76:51: warning: sizeof on array function parameter will
return size of 'const VGfloat *' (aka 'const float *') instead of
'const VGfloat [2]' [-Wsizeof-array-argument]
   memcpy(glyph->glyph_origin, glyphOrigin, sizeof(glyphOrigin));

NOTE: This is a candidate for the 8.0 branch.

108d544cae util: fix uninitialized table
Most of the 256 values in the 'generic_to_slot' table were supposed to
be initialized with the default value 0xff, but were left at zero
(from CALLOC_STRUCT()) instead.

Noticed by clang:

u_linkage.h:60:31: warning: argument to 'sizeof' in 'memset' call is the same expression as the destination;
      did you mean to provide an explicit length? [-Wsizeof-pointer-memaccess]
   memset(table, 0xff, sizeof(table));
          ~~~~~               ^~~~~

Also fix a signed/unsigned comparison and a comment typo here.

546abd2503 util: fix undefined behavior
container_of() can legally return anything, even invalid addresses
that cause segfaults, when 'sample' is an uninitialized pointer.

Bug exposed by clang.
