d3d10 requires that cube corners are filtered with accurate weights (that
is, the weight of the non-existing corner texel should be evenly distributed

This requires us to use different filtering code, since we need per-texel
weights which our 2d lerp doesn't (and can't) do. And of course the (now
per element) weights need to be adjusted too for it to work.
Invoke the new filtering code whenever there's an edge to keep things simpler,
as it will work for edges too not just corners but of course it's only needed
with corners.
More ugly code for not much gain but at least a hacked up cubemap demo
shows very nice corners now... Not sure yet if and how this should be
configurable...

match the source. The symbol list may change in the future and we won't
notice without manually running the tool again.
- Use objcopy --localize-hidden to automatically demote our symbols to
locals. This didn't work on i965 due to c++ weak symbols (which can't
be localized), but could work on i915. We could do it on i915 only, but
it does produce libtool warnings at link time due to libtool not knowing
if the resulting .o file is safe to link (stupid libtool). Plus you end
up with different symbols of the same name, which is confusing for
debugging too. On the other hand, no future symbol conflicts long term.
- Write our own libelf tool that handles c++ weak symbols like we want and
apply it to all drivers. All the downsides of above, but applies
uniformly across drivers.
- Edit the files to just rename all the i915 or i965 symbols that
conflict. There are on the order of 100 that have a prefix we used to
share, so it would take a bit of typing. Fewest downsides, but still
can have conflicts long term.
Ultimately, this is the least invasive change at the moment, and we can
see if the "more symbol conflicts appear later" thing is a real concern or
not.

in the i965 (gen4) PRM saying that instruction compression could not
be used in align16 mode. I couldn't find similar text in later
hardware docs, and I observed problems trying to use instruction
compression on align16 mode on Ivy Bridge, so I assumed that the
restriction still applied and the associated documentation had simply
been lost.
After consultation with the hardware engineers, it turns out this is
not the case. In point of fact, the restriction was dropped in gen5,
re-introduced in Ivy Bridge, and dropped again in Haswell. The reason
I didn't notice this is that in the Ivy Bridge documentation, the
restriction was in a different section, and described using different
language.
Now that we know that the restriction only applies to Gen4 and Ivy
Bridge, we can limit the unrolling to those platforms.

glsl: Simplify the interface to link_invalidate_variable_locations
The unit tests added in the previous commits prove some things about the
state of some internal data structures. The most important of these is
that all built-in input and output variables have explicit_location
set. This means that link_invalidate_variable_locations doesn't need to
know the range of non-generic shader inputs or outputs. It can simply
reset location state depending on whether explicit_location is set.
There are two additional assumptions that were already implicit in the
code that comments now document.
- ir_variable::is_unmatched_generic_inout is only used by the linker
when connecting outputs from one shader stage to inputs of another
shader stage.
- Any varying that has explicit_location set must be a built-in. This
will be true until GL_ARB_separate_shader_objects is supported.
As a result, the input_base and output_base parameters to
link_invalidate_variable_locations are no longer necessary, and the code
for resetting locations and setting is_unmatched_generic_inout can be
simplified.

glsl: When constructing a variable with an interface type, set interface_type
Ever since the addition of interface blocks with instance names, we have
had an implicit invariant:
var->type->is_interface() ==
(var->type == var->interface_type)
The odd use of == here is intentional because !var->type->is_interface()
implies var->type != var->interface_type.
Further, if var->type->is_array() is true, we have a related implicit
invariant:
var->type->fields.array->is_interface() ==
(var->type->fields.array == var->interface_type)
However, the ir_variable constructor doesn't maintain either invariant.
That seems kind of silly... and I tripped over it while writing some
other code. This patch makes the constructor do the right thing, and it
introduces some tests to verify that behavior.
v2: Add general-ir-test to .gitignore. Update the description of the

glsl/linker: Allow mixing of desktop GLSL versions.
Previously, Mesa followed the linkage rules outlined in the GLSL
1.20-1.40 specs, which (collectively) said that GLSL versions 1.10 and
1.20 could be linked together, but no other versions could be linked.
In GLSL 4.30, the linkage rules were relaxed so that any two desktop
GLSL versions can be linked together. This change was made because it
reflected the behaviour of nearly all existing implementations (see
Khronos bug 8463). Mesa was one of the few (perhaps the only)
exceptions to prohibit cross-linking of some GLSL versions.
Since the GLSL linkage rules were deliberately relaxed in order to
match the behaviour of existing implementations, it seems appropriate
to relax the rules in Mesa too (even though Mesa doesn't support GLSL
4.30 yet).
Note that linking ES and desktop shaders is still prohibited, as is
linking ES shaders having different GLSL versions.
