* 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
* 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>
in 3943 the new tests should have failed, but didn't due to the AnyVUID
check not handling case with trailing whitespace. Added trimming to handle
it as easily might happen again in future
If enabled the following targets will be created:
* `${SPIRV_TOOLS}-static` - `STATIC` library. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
* `${SPIRV_TOOLS}` - will alias to one of above, based on BUILD_SHARED_LIBS.
If disabled the following targets will be created:
* `${SPIRV_TOOLS}` - either `STATIC` or `SHARED` based on the new `SPIRV_TOOLS_LIBRARY_TYPE` flag. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
Defaults to `ON`, matching existing build behavior.
This flag can be used by package maintainers to ensure that all libraries are built as shared objects.
* 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
Currently the validator, when checking an instruction is in the correct
section, always advances the current section. This means if we have an
instruction from a previous section we'll end up reporting it as invalid
in a function definition. This error is confusing.
This CL updates the validator to check if the given opcode is from a
previous layout section before advancing the current section. If it is
from a previous layout section an error is emitted.
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
Some OpenCL.DebugInfo.100 instructions such as DebugGlobalVariable
and DebugLocalVariable have the Type operand. This commit allows them to
use DebugTypeTemplate for the Type operand.
The updated OpenCL.DebugInfo.100 spec says that we can use
variable for "Component Count" operand of DebugTypeArray i.e.,
DebugLocalVariable or DebugGlobalVariable. This commit updates spirv-val
based on the spec update.
* Generate ext inst table for reflection
* Change build to use grammar files from SPIRV-Headers instead of
SPIRV-Tools
* Add enum for clspv reflection extended instruction set
* count it as non-semantic
* validate clspv reflection extended instruction set
* Remove local extended inst sets
* update headers deps
* Update nbuilds to use grammars from SPIRV-Headers instead of
local duplicates
Rename the `${SPIRV_TOOLS}` target to `${SPIRV_TOOLS}-static` and alias `${SPIRV_TOOLS}` to either `${SPIRV_TOOLS}-static` or `${SPIRV_TOOLS}-shared` depending on `BUILD_SHARED_LIBS`.
Re-point all internal uses of `${SPIRV_TOOLS}` to `${SPIRV_TOOLS}-static`.
`${SPIRV_TOOLS}-static` is explicitly renamed to just `${SPIRV_TOOLS}` to ensure the name does not change from current behavior.
Build the `SPIRV-Tools-*` libraries as static, as this is what they always were.
Force the external targets `gmock` and `effcee` to be built statically. These either do not support being built as shared libraries, or require special flags.
Issue: #3482
* spirv-val: Pipes are no longer required for OpenCL 1.2 EP
This was removed from the OpenCL SPIR-V Environment Specification via
https://github.com/KhronosGroup/OpenCL-Docs/pull/56.
* spirv-val: Sort headers according to clang-format
* spirv-val: Groups capability is required since OpenCL 2.0
Now that WebGPU ingests WGSL instead of SPIR-V,
there is no need to be so strict about the memory model.
Allow any memory model that is already allowed by Vulkan 1.0,
either directly or via an existing.
Fixes#3529
* Make BasicBlock::reachable() only consider static reachability
* Fix reachability calculation to be independent of block order
* add tests
* Add validation that input/output locations are assigned correctly
* Account for component assignment
* Account for 4 components per location and track the combined
coordinate
* Account for multiple output indexes
* handle specifically arrayed variables
* Arrayed variables that specify a component get locations determined
per index of the array for the sub type
* Added tests that check locations and components can be assigned
to interleave an array's locations and components
* Fix up which interfaces are allowed to be arrayed for various shader
stages based on glslang
ImageGatherBiasLodAMD makes it possible to use the Bias and Lod image
operands with OpImageGather and OpImageSparseGather. This commit makes
sure the validator checks for that capability before reporting errors
and adds a few positive tests.
According to SPV_AMD_shader_image_load_store_lod spec, Lod operand is
valid with OpImageRead, OpImageWrite, or OpImageSparseRead if the
extension is enabled.
Fixes#3139
* If the header of the construct is also a merge block, jump to the
associated header instead of the immediate dominator
* prevents spurious failures from unrelated constructs
* new tests
* Allow OpExtInst for DebugInfo between secion 9 and 10
Fixes#3086
* Handle spirv-opt errors on DebugInfo Ext
* Add IR Loader test
* Fix ir loader bug
* Handle DebugFunction/DebugTypeMember forward reference
* Add test cases (forward reference to function)
* Support old DebugInfo extension
