1b313eedb5 glsl: Silence warnings in the uniform initializer test about 16-bit types
They should probably get unit tests implemented, but this cleans up a
bunch of warnings in my build for now.

f32b01ca43 glsl/linker: remove ubo explicit binding handling
This is already handled at link_uniform_blocks, specifically at
process_block_array_leaf.

Additionally, this code was not handling correctly arrays of
arrays. When creating the name of the block to set the binding, it
only took into account the first level, so any attempt to set a
explicit binding on a array of array ubo would trigger an assertion.

Next patch will allow disk_cache instance to be created without

This reduces SGPRs spilling in MadMax, and it also reduces
number of SGPRs in DOW3 and F12017. The number of waves slightly
decreases in F1 but I don't see any performance changes after
benchmarking it. Talos and Serious Sam are not affected because
they don't use any push constants.

ef439a4fdc spirv: split constant initializers on in/out structs
The SPIR-V parser splits in/out struct variables and creates
a separate variable for each first-level member of the struct.
When the struct variable has an initializer this means that we also
need to split the initializer.

4195eed961 glsl/linker: check same name is not used in block and outside
According with OpenGL GLSL 3.20 spec, section 4.3.9:

  "It is a link-time error if any particular shader interface
   contains:
     - two different blocks, each having no instance name, and each
       having a member of the same name, or
     - a variable outside a block, and a block with no instance name,
       where the variable has the same name as a member in the block."

This fixes a previous commit 9b894c8 ("glsl/linker: link-error using the
same name in unnamed block and outside") that covered this case, but
did not take in account that precision qualifiers are ignored when
comparing blocks with no instance name.

With this commit, the original tests
KHR-GL*.shaders.uniform_block.common.name_matching keep fixed, and also
dEQP-GLES31.functional.shaders.linkage.uniform.block.differing_precision
regression is fixed, which was broken by previous commit.

186f03cfb0 mesa: Put materials at the end of the generic block.
The materials are now moved to the end of the
generic attributes block to the range 4-15.

Before, the way the position and generic 0 attribute
is handled was dependent on the presence and kind of
the currently attached vertex program. With this
change the way the position attribute and the generic 0
attribute is treated only depends on the enabled
flag of those two arrays.
This will later help to untangle the update dependencies
between enabled arrays and shader inputs.

If both comparisons are used as sources for instructions other than the
iand, this transformation is detrimental.  If the non-identical value in
both compares is constant, the fmin or fmax will be constant-folded
away, so the transformation is always a win.

3941cba0f7 nir: Be more conservative about rearranging or-compounded compares
If both comparisons are used as sources for instructions other than the
ior, this transformation is detrimental.  If the non-identical value in
both compares is constant, the fmin or fmax will be constant-folded
away, so the transformation is always a win.

09cd484d61 nir: partially revert c2acf97fcc
c2acf97fcc changed the use of double_inputs_read to be
inconsitent with its previous meaning. Here we re-enable the
gather info code that was removed as the modified code from
c2acf97fcc now uses the double_inputs member rather than
double_inputs_read.

This change allows us to use double_inputs_read with gallium
drivers without impacting double_inputs which is used by i965.

We also make use of the compiler option vs_inputs_dual_locations
to allow for the difference in behaviour between drivers that handle
vs inputs as taking up two locations for doubles, versus those that
treat them as taking a single location.

5b8de4bdff nir: add vs_inputs_dual_locations compiler option
Allows nir drivers to either use a single or dual locations for

i965 uses dual locations for both OpenGL and Vulkan drivers, for
now gallium OpenGL drivers only use a single location.

The following patch will also make use of this option when

f63e05ae9e compiler: tidy up double_inputs_read uses
First we move double_inputs_read into a vs struct in the union,
double_inputs_read is only used for vs inputs so this will
save space and also allows us to add a new double_inputs field.

We add the new field because c2acf97fcc changed the behaviour
of double_inputs_read, and while it's no longer used to track
actual reads in i965 we do still want to track this for gallium
drivers.

9b894c88a6 glsl/linker: link-error using the same name in unnamed block and outside
According with OpenGL GLSL 4.20 spec, section 4.3.9, page 57:

   "It is a link-time error if any particular shader interface
    contains:
      - two different blocks, each having no instance name, and each
        having a member of the same name, or
      - a variable outside a block, and a block with no instance name,
        where the variable has the same name as a member in the block."

This means that it is a link error if for example we have a vertex
shader with the following definition.

  "layout(location=0) uniform Data { float a; float b; };"

and a fragment shader with:

  "uniform float a;"

As in both cases we refer to both uniforms as "a", and thus using
glGetUniformLocation() wouldn't know which one we mean.

This fixes KHR-GL*.shaders.uniform_block.common.name_matching.

2083a14179 meson: Use dependencies for nir
This creates two new internal dependencies, idep_nir_headers and
idep_nir. The former encapsulates the generation of nir_opcodes.h and
nir_builder_opcodes.h and adding src/compiler/nir as an include path.
This ensures that any target that needs nir headers will have the
includes and that the generated headers will be generated before the
target is build. The second, idep_nir, includes the first and
additionally links to libnir.

This is intended to make it easier to avoid race conditions in the build
when using nir, since the number of consumers for libnir and it's
headers are quite high.
