Jason Ekstrand 34a39e91ba spirv/nir: Don't increment coord_components for array lod queries
For lod query instructions, we really don't care whether or not the sampler
is an array type because that doesn't factor into the LOD.

Jason Ekstrand 7c7acf53b2 spirv/nir: Add support for shadow samplers that return vec4
While SPIR-V technically doesn't support "old style" shadow, the
shadow-compare gather instruction does return a vec4 so we need to be able
to set the old_style_shadow bit in NIR.

Jason Ekstrand 2ddefd03b7 spirv/nir: Fix some texture opcode asserts
We can't get an lod with txf_ms and SPIR-V considers textureGrad to be an
explicit-LOD texturing instruction.

Kenneth Graunke ac1181ffbe compiler: Rename INTERP_QUALIFIER_* to INTERP_MODE_*.
Likewise, rename the enum type to glsl_interp_mode.

Beyond the GLSL front-end, talking about "interpolation modes" seems
more natural than "interpolation qualifiers" - in the IR, we're removed
from how exactly the source language specifies how to interpolate an
input.  Also, SPIR-V calls these "decorations" rather than "qualifiers".

Generated by:
$ find . -regextype egrep -regex '.*\.(c|cpp|h)' -type f -exec sed -i \
  -e 's/INTERP_QUALIFIER_/INTERP_MODE_/g' \
  -e 's/glsl_interp_qualifier/glsl_interp_mode/g' {} \;

Giuseppe Bilotta 60a27ad122 Remove wrongly repeated words in comments
Clean up misrepetitions ('if if', 'the the' etc) found throughout the
comments. This has been done manually, after grepping
case-insensitively for duplicate if, is, the, then, do, for, an,
plus a few other typos corrected in fly-by

v2:
    * proper commit message and non-joke title;
    * replace two 'as is' followed by 'is' to 'as-is'.
v3:
    * 'a integer' => 'an integer' and similar (originally spotted by
      Jason Ekstrand, I fixed a few other similar ones while at it)

Jason Ekstrand 526a8de22d nir/spirv: Make a decoration switch complete
Getting rid of the default case makes the compiler warn if we are missing
cases.  While we're here, we also add the one missing case.

Jason Ekstrand 62c6e94bd6 nir/spirv: Make unhandled decorations and capabilities non-fatal
glslang frequently throw bogus decorations into shaders.  While we are free
to assert-fail, it's a bit nicer to the application to just warn.

Jason Ekstrand 5a1e56f344 nir/spirv: Complete the list of capabilities
Previously we supported a subset of capabilities and just left a default
case for the others.  It's time to stop being lazy and actually audit the
capabilities.  This should bring them up-to-date with reality.

Jason Ekstrand 961369d597 nir/spirv: Add explicit handling for all decorations
From time to time we have had cases where glslang has added a decoration we
don't handle and it has caused problems.  This audit ensures that, for
every decoration, we either handle it or hit an unreachable() with an
accurate description of why we don't have to.

Kenneth Graunke de45da6a8c spirv: Handle the PixelCenterInteger execution mode.
This isn't allowed by Vulkan, but might be useful someday for
SPIR-V in OpenGL (if that ever becomes a thing).  It's easy enough
to hook up, and as precedent, we already do so for OriginLowerLeft.

Matt Turner b1e6d069da spirv: Properly size the src[] array.
Operations like nir_op_bitfield_insert have four arguments, and Coverity
isn't privy to the fact that 4-argument operations aren't possible here,
so it thinks this can lead to memory corruption. Just increase the size
of the array to quell any fears.
