There are some cases where the scheduler can get itself into impossible
situations, by scheduling the wrong write to pred or addr register
first. (Ie. it could end up being unable to schedule any instruction if
some instruction which depends on the current addr/reg value also
depends on another addr/reg value.)
To solve this we'd need to be able to insert extra mov instructions
(which would also help when register assignment gets into impossible
situations). To do that, we'd need to move the nop padding from sched
into legalize.
But to start with, just detect when we get into an impossible situation
and bail, rather than sitting forever in an infinite loop. This way it
will at least fall back to the old compiler, which might even work if
you are lucky.

All of the GL image enums fit in 16-bits.
Also move the fields from the anonymous "image" structucture to the next
higher structure. This will enable packing the bits with the other
bitfield.

I actually screwed that up in 754319490f,
mistakenly thinking the code actually wanted the non-nan result before.
So, introduce that missing nan behavior case and use that instead.
For sse, there's no actual change in the resulting code at all, the fallback
code wouldn't have done the right thing though.
Of course, the actual issue I saw with pow() was completely unrelated...

Pretty trivial, just fill in the offsets and such. The implementation
is near 100% copy and paste from llvmpipe. Should be useful for debugging.
No piglit change when not using SOFTPIPE_USE_LLVM=1.
Now that it can do the same tests with and without using llvm for vs/gs,
with llvm more pass, the only things failing only with llvm seems to be
edgeflags tests and vs/gs-pow-float-float (and for the latter I'm not
convinced the zero tolerance it requires is somehow mandated by glsl).

Pretty easy, just make sure that all paths testing for PIPE_TEXTURE_CUBE
also recognize PIPE_TEXTURE_CUBE_ARRAY, and add the layer * 6 calculation
to the calculated face.
Also handle it for texture size query, looks like OpenGL wants the number
of cubes, not layers (so need division by 6).
No piglit regressions.
v2: fix up adding cube layer to face for seamless filtering (needs to happen
after calculating per-sample face). Undetected by piglit unfortunately.

Not sure why it was there but it is definitely not an error if gs outputs are
infs/nans. Besides, the outputs can be ints, in which case any small negative
number asserted.
This fixes piglit's texelFetch gs isamplerXX crashes with softpipe (down from

piglit tex-miplevel-selection nowadays doesn't use repeat wrap mode due to
sampler objects any longer, however at the time of the clear the wrap mode
is still illegal and at this point we get to verify the state, including
samplers (even though they won't get used), and because mesa doesn't treat
it as an incomplete texture as the spec says it should, we hit the assertion.
Just warn about this for now instead.
Gets crashes down from 44 to 14 in a piglit run (all were in various tests of
tex-miplevel-selection with texture rectangles). Though just about all
tex-miplevel-selection tests fail anyway for other reasons.

Just handle as ordinary 2d / 2d array resources. Prevents an assertion failure

softpipe being broken).

This was meant for softpipe to not crash at some point if vertex texturing
was used. It is, however, fishy because it uses values from
draw_set_samplers/draw_set_sampler_views and not from the shader key. Albeit
we should still in all cases actually generate a new shader if this changes
(because the samplers and views themselves are in the key) I don't want to
think again wondering if that's really correct in the future.
Besides, at least today, it does not actually work for softpipe, as this was
relying on softpipe not actually calling draw_set_samplers/sampler_views at
all - I've verified it crashes regardless (if there were a tex instruction in
the vs, which normally should not happen anyway). For drivers which do indeed
not call these functions because they don't support vertex texturing at all
(r300), this should still not crash because the static texture data is all
zero, which causes the sampling functions to take an early out (same as is done
if no texture is bound at the slot used for sampling - verified with hacked up
softpipe).

mesa was creating a cube map array texture with just one layer, which is
not legal. This caused an assertion failure when using that texture later
in llvmpipe (when enabling cube map arrays) since it verifies the number
of layers in the view is divisible by 6 (the sampling code might well crash
randomly otherwise) with piglit glsl-resource-not-bound CubeArray -fbo -auto.
v2: use appropriately sized texel array...

This reverts commit 6a19bb56e0.
The above commit disabled the default build of xvmc as the xvmc tests
were failing. As pointed out by Ilia, the tests are "broken by design"

installed and setup on the workstation.
With previous commit we moved the programs from the 'make check' to
