In commit 800610f (i965/fs: Improve accuracy of dFdy() to match
dFdx()) I unrolled the high-accuracy dFdy() computation from a single
SIMD16 instruction to two SIMD8 instructions because of text I found
in the i965 (gen4) PRM saying that instruction compression could not

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

10 years agoglsl: When constructing a variable with an interface type, set interface_type
Ian Romanick [Wed, 2 Oct 2013 23:19:59 +0000 (16:19 -0700)]
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
ir_variable invariant for arrays in the commit message.  Both suggested

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.

gallivm: implement seamless cube filtering

For seamless cube filtering it is necessary to determine new faces and new

to happen is very "asymmetric" wrt face, x/y under/overflow), further
complicated by the fact that if the 4 samples are in a corner (meaning we
only have actually 3 samples, and all 3 are on different faces) then
falling off the edge is happening _both_ on x and y axis simultaneously.
There was a noticeable performance hit in mesa's cubemap demo when seamless
filtering was forced on (just below 10 percent or so in a debug build, when
disabling all filtering hacks, otherwise it would probably be a bit more) and
when always doing the logic, hence use a branch which it only does it if any
of the pixels in a quad (or in two quads) actually hit this. With that there
was no measurable performance hit in the cubemap demo (neither in a debug nor
release buidl), but this will vary (cubemap demo very rarely hits edges).
Might also be different on other cpus, as this forces SoA sampling path which
potentially can be quite a bit slower.
Note that as for corners, this code gets all the 3 samples which actually
exist right, and the 4th texel will simply be the same as one of the others,
meaning that filter weights will be a bit wrong. This however should be
enough for full OpenGL (but not d3d10) compliance.
