Fixes#4469
* Checks that decorations only usable with structure members are not
used by OpDecorate or OpDecorateId
* Checks that decorations not allowed on structure members are not used
with OpMemberDecorate
* Checks decoration targets for most core decorations
* Performs some Vulkan specific validation on deorations
* 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
* 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

MeshShadingNV: enables PrimitiveId, Layer, and ViewportIndex
Co-authored-by: Daniel Koch <dkoch@nvidia.com>
Don't pass a constructed string as an argument to
ValidateNotCalledwithExecutionModel. That method is captured via
std::bind and it ends up using lots of stack space.
Instead, pass in:
- a Vulkan validation unique ID as an integer instead,
(with -1 meaning no VUID), and
- the const char* for the explanator text.
* spirv-val: Allow the ViewportIndex and Layer built-ins when their corresponding SPIR-V 1.5 capabilities are present
* Added tests for OpCapability ShaderViewportIndex and OpCapability ShaderLayer
The Vulkan 1.2.152 headers/spec now include Valid Usage IDs (VUID)
for every BuiltIn. This change adds labeling to help aid tracking
the coverage gap in Vulkan targeted validation. This is done with
a script in the Validation Layers that parses the source for VUID
strings, both that there is an implementation and a test for it.
There are 2 main changes:
1. A VUID string is added where applicable. It is wrapped in a function
that at runtimes checks if Vulkan is the target so that other targets
will not be effected as the output error only changes for Vulkan and
the overhead only occurs if there is an error at all.
2. For unit test, a new parameter value was added to allow make sure
that for each VUID there is a matching test. There are cases where the
same unit test checks multiple VUs via the parameter feature of gtest.
For this, I added a custom gMock Matcher to simply loop over a list
of VUID strings
Also add a Builtin test generator variant that takes
capabilities and extensions.
Tests
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
accepted as Inputs in Vertex, Fragment, TessControl, TessEval, Geometry,
and Compute.
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
accepted as Inputs in MeshNV and TaskNV shaders.
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
accepted as Inputs in the 6 ray tracing stages
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
NOT accepted as Outputs.
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
NOT accepted as non-scalar integers (f32, uvec3)
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
NOT accepted as non-32-bit integers (u64)
This CL adds in the specific checks required for WebGPU, enables
running the builtin checks for WebGPU, and refactors the existing
testing infrastructure to support testing the new checks.
This PR is part of resolving #2276
The Vulkan specification does not permit use of the VertexId and
InstanceId BuiltIn decorations, so add a check to ensure they are not
being used when the target environment is Vulkan.
This commit will change the message for unknown extensions from an error
to a warning.
Code was added to limit the number of warning messages so that consummer
of the messages are not overwhelmed. This is standard practice in
compilers.
Many other issues were found at while looking into this. They have been
documented in #1950.
Fixes http://crbug.com/875547.
This CL moves the various validate files into the val/ directory with
the rest of the validation infrastructure. This matches how opt/ is
setup with the passes with the infrastructure.
