This patch supports new Intel extensions added via
https://github.com/KhronosGroup/SPIRV-Headers/pull/176
SPV_INTEL_fooat_controls2 requires extra support to add
two new operand types:
SPV_OPERAND_TYPE_FPDENORM_MODE
SPV_OPERAND_TYPE_FPOPERATION_MODE
* Work around GCC-9 warning treated as error
```
../source/opt/instruction.h:101:23: error: '*((void*)& operand +32)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
101 | uint64_t result = uint64_t(words[0]);
```
* Migrate all Kokoro build scripts over to use the docker VM image
Required updating the NDK SDK and build scripts, as well as the check_copyright for handling 2021.
Propagating the OpLine/OpNoLine to preserve the debug information
through transformations results in integrity check failures because of
the extra line instructions. This commit lets spirv-opt skip the
integrity check when the code contains OpLine or OpNoLine.
* tools/linker: Error out on unrecognized options
Fixes#4083.
* tools/linker: Use early returns when parsing options
This was already the case for some linker options, and other tools were
doing so for all of their options.
* tools/linker: Rework the usage output
* The new formatting for long options taking a value makes it explicit
that there is no equal sign between the option name and the value.
* The options are sorted by lexicographical order.
* Change the option formatting from 90 columns to 80, to match the other
tools.
* tools/linker: Change the default environment to spv1.5
* tools/linker: Change the default output to spv.out
Instead of writing to the standard output when the "-o" option is not
specified, the resulting linked SPIR-V binary will be written to
"spv.out".
One can still have the output sent to the standard output by specifying
"-o -".
* tools/linker: Update the reported target for --version
Running `spirv-link --version` will now report the currently selected
environment.
* tools/linker: Sort header includes
* linker: Improve module-related error messages
* Use 1-based indexing of modules;
* Say which module could not be built;
* Use the correct total number of input modules in the error message
when one fails to build.
When there is an array of strutured buffers, desc sroa will only split
the array, but not a struct type in the structured buffer. However,
the calcualtion of the number of binding a struct requires does not take
this into consideration. This commit will fix that.
Avoid generating OpPhi on void types, and allow the transformation to
take place on regions that produce pointer and sampled image result
ids if such ids are not used after the region.
Fixes#3787.
* validation: tighter validation of multisampled images
- if MS=1, then Sample image operand is required
- Sampling operations are not permitted when MS=1
Fixes#4057, #4058
* Fail early for multisampled image for sampling, dref, gather
* validate StorageImageMultisampled capability
The StorageImageMultisampled capability is required when declaring
an image type with with Multisampled==1 and it's a storage image (Sampled == 2)
Fixes#4061
* Allow SubpassData with Multisampled and Sampled==2
Similar to [1] DCE should be ran when this extension is enabled to
prevent unused bindings from showing up (in particular atomic counters
attached to buffers).

The eliminate dead member pass is written assuming that the index to an
OpAccessChain will be a 32-bit integer or 64-bit integer. That is
changed to work for any width 64-bits or less.

* Add validation for ray tracing builtins
- Remove existing InstanceId testing that was combined with VertexId in awkward ways.
- Rather than adding a new set of functions for each ray tracing builtin, add
an error table that maps the builtin ID to the 3 common VUIDs for each builtin
(I could see this being extended for other builtins in the future).
- add F32 matrix validation function
- augment existing PrimitiveId validation to verify Input storage class for the
RT stages this is accepted in, and correct the list of stages that it is actually
accepted in (only Intersection / Any Hit / Closest Hit)
* add testing for ray tracing builtins
- remove exising InstanceId testing as it was tangled in with VertexId in now weird ways
and combine it with the new tests
- add testing for ray tracing builtins
- builtins accepted in the same stages and of the same types are combined into test functions
- add some new matrix types to the code generator so they can be used for testing
This instruments ImageRead, ImageWrite and ImageFetch when applied to
texel buffers.
Also add new (but not yet generated) buffer OOB error codes differentiated
for VUID classification.
* BuildModule: optionally avoid adding new OpLine instructions
Fixes#4029 for my use case
* Fix formatting
* Create last_line_inst_ only if doing extra line tracking
* Update to final ray tracing extensions
Drop Provisional from ray tracing enums
sed -ie 's/RayQueryProvisionalKHR/RayQueryKHR/g' **/*
sed -ie 's/RayTracingProvisionalKHR/RayTracingKHR/g' **/*
Add terminator support for SpvOpIgnoreIntersectionKHR and SpvOpTerminateRayKHR
Update deps for SPIRV-Headers
* Update capability dependencies for MeshShadingNV
