There is inconsistencies between the different specs about whether or
not this capability is required/allowed, so tooling like glslang
currently ignores it. Once this is resolved the check and test can be
re-enabled.
* Only check for binding and descriptor set on variables that are
statically used by an entry point
* updated tests and added a couple new ones
* new method for collecting entry points that statically reference an
id
* Validate OpForwardPointer
The validator does not have a a check that OpForwardPointer is giving
a forward reference to a pointer type. We add that check.
https://crbug.com/910852
* Remove more specialized check.
There was a check that the forward pointer is actually a poiner type,
but it was only done if it was used in a struct. This was too specific.
Remove it in favour of the more general check that was added.
* Format
* Check the storage type in OpTypeForwardPointer
* Fix typo is test case epxected results.
Fixes#2147
* Checks that device scope is not used for availability and visibility
operations unless VulkanMemoryModelDeviceScopeKHR capability is present
* implemented for atomics, barriers and memory instructions currently
This CL changes the id/name output from the validator to always use a
consistent id[%name] style. This removes the need for getIdOrName. The
name lookup is changed to use the NameMapper so the output is consistent
with what the disassembler will produce.
Fixes#2137
* Validate uses of ids defined in unreachable blocks.
For some reason we do not make sure the uses of ids that are defined
in unreachable blocks are dominated by their def. This is causing
invalid code to pass the validator.
Fixes#2143
* Add test for unreachable code after a return.
We want to allow code like:
```
void foo() {
a = ...;
...
return; // for debugging
<use of a>;
...
}
```
I added a test to make sure that something like this is still accepted
by the validator.
* Add test for unreachable def used in phi.
Fixes#2104
* Checks the rules for logical addressing and variable pointers
* Has an out for relaxed logical pointers
* Updated PassFixture to expose validator options
* enabled relaxed logical pointers for some tests
* New validator tests
Restrict capabilities to WebGPU spec
This covers whitelisting Matrix, Shader, Sampled1D, Image1D,
DerivativeControl, and ImageQuery. These are the allowed capabilities
that don't require an extension. Whitelisting VulkanMemoryModelKHR
will be handled by whitelisting its extension in a seperate patch.
Fixes#2101
Fixes https://crbug.com/906669
* Don't free diagnostics in spvBinaryParse
* When invoking the parser we wish to ignore the error messages from,
instead create a hijacked context and replace the message consumer with
a null consumer
Make sure that initialized variable have correct storage class
For WebGPU and Vulkan environments, variables must have the storage
class; Output, Private, or Function, if they have an initializer.
Fixes#2071
Adding validation that the addressing declared by OpMemoryModel is
Logical and the memory model declared is VulkanKHR. Updating a bunch
of tests that were broken by this.
Fixes#2060
Check forbidden Annotation instructions for WebGPU env
From the WebGPU SPIR-V Execution Enviroment spec:
OpDecorationGroup, OpGroupDecorate, OpGroupMemberDecorate are not
allowed.
Fixes#2062
Validate that debugging instructions are not present for WebGPU
For WebGPU execution environments, check that all of the debug
instructions have already been stripped before validation.
Fixes#2063
Ban sequentially consistent with VulkanKHR
* Added validation check that SequentiallyConsistent memory semantics
are not used if the memory model is VulkanKHR
* Added tests
* Fixed a bug in evaluating constant 32-bit integers and updated some
handling to avoid inferring a value from a spec constant default
Remaining memory semantics validation
* Adds checks that OutputMemoryKHR, MakeAvailableKHR and MakeVisibleKHR
are only used if the VulkanMemoryModelKHR capabailty is present
* Added checks that MakeAvailableKHR requires release semantics
* Added checks that MakeVisibleKHR requires acquire semantics
* Added checks that MakeAvailableKHR and MakeVisibleKHR require a
storage class
Adds validator option to specify scalar block layout rules.
Both VK_KHR_relax_block_layout and VK_EXT_scalar_block_layout can be
enabled at the same time. But scalar block layout is as permissive
as relax block layout.
Also, scalar block layout does not require padding at the end of a
struct.
Add test for scalar layout testing ArrayStride 12 on array of vec3s
Cleanup: The internal getSize method does not need a round-up argument,
so remove it.
These are bookend passes designed to help preserve line information
across passes which delete, move and clone instructions. The propagation
pass attaches a debug line instruction to every instruction based on
SPIR-V line propagation rules. It should be performed before optimization.
The redundant line elimination pass eliminates all line instructions
which match the previous line instruction. This pass should be performed
at the end of optimization to reduce physical SPIR-V file size.
Fixes#2027.
From the Vulkan 1.1 spec 14.5.2:
Variables identified with the Uniform storage class are used to access
transparent buffer backed resources. Such variables must be typed as
OpTypeStruct, or an array of this type.
Fixes#1949
Validate variable types for UniformConstant storage in Vulkan (#2008)
From the Vulkan 1.1 spec 14.5.2:
Variables identified with the UniformConstant storage class are used
only as handles to refer to opaque resources. Such variables must be
typed as OpTypeImage, OpTypeSampler, OpTypeSampledImage, or an array
of one of these types.
Fixes#2008
