Fixes#2488
* Validator doesn't identify back-edge of the loop, so the merge is
never set
* Construct::blocks() has safe uses of `merge` so the assert can be
removed
* Added a test
Changing the stored value for a sampled image consumer to be the
instruction instead of result ID, since not all instructions have
result IDs. Using result IDs led to a potential crash when using
OpReturnValue, which doesn't have a result ID. OpReturnValue is not a
legal consumer, but the validator needs to look at the instruction to
determine this, thus storing the pointer to the instruction, instead
of trying to fetch the pointer using the instruction.
Issue #1528 covers fixing the check.
Fixes#2463
If relax-logical-pointer is enabled, this commit makes Validator
accept function param even when its Storage Class is different from
the expected one.
Related to #2423, #2430
In WebGPU all blocks are required to be reachable, unless they are one of two
specific degenerate cases for merge-block or continue-target. This PR adds in
checking for these conditions.
Fixes#2068
In relaxed addressing mode, we want to accept non memory objects
because this is a very natural translation of hlsl. It should be fixed
by legalization by inlining the calls.
* Remove use of deprecated googletest macro
INSTANTIATE_TEST_CASE_P has been deprecated. We need to use
INSTANTIATE_TEST_SUITE_P instead.
* Remove extra commas from test suites.
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
In a recent PR, we allowed a forward reference for the element type in
an array declaration. However, we do not have other check to make sure
the forward reference is a pointer type first reference in
OpTypeForawrdPointer. We add that check.

Broader check for ids that require a type
Fixes https://crbug.com/911700
* Adds a broader check for when id operands require a type
* updated a few tests
* added a test to catch the original issue
* Added additional changes for the new AccelerationStructureNV type.
* Added NVIDIA ray tracing storage classes for checking in ValidateVariable.
* For NVIDIA ray tracing storage classes added test to load bool type (allowed) in new storage class.
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
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
We had a test that checks that a spirv binary where the depth of the
deepest nested construct is just below the default limit. This test
would take a long time causing a timeout in some builds. We are
questioning the value of the test since we already have a test that can
tell us if we are within a custom limit. We will remove the test.
Add tests for matrix type data rule validation
This covers the data rules for matrix types specified in the SPIR-V
spec, section 2.16.1, and the WebGPU SPIR-V Execution Environment
spec.
