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
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
