* Can only be used with Vulkan memory model
* Can only be used with atomics
* Bit setting must match for compare exchange opcodes
* Updated memory semantics checks to allow constant instructions
generally with CooperativeMatrixNV
Recent change to the spec restricted the valid values for Memory
Semantics in OpAtomics* in the WebGPU env. Implementing enforcing
these changes.
Fixes#2499
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.
