SPIR-V 1.5 Testing

[bashbaug]

Here is a similar tracking issue for SPIR-V 1.5 testing.

I believe we only need to add two new test cases for SPIR-V 1.5, since SPIR-V 1.5 was primarily Vulkan-focused:

• New Behavior:
  • [ ] OpBitcast supports bitcasts between a pointer and an integer vector.
  • [ ] OpGroupNonUniformBroadcast supports a non-constant (but dynamically uniform) broadcast index.

[bashbaug]

In case it is helpful, here are my SPIR-V 1.5 notes:

Required Support

• OpBitcast supports bitcasts between a pointer and an integer vector.
• OpGroupNonUniformBroadcast supports a non-constant (but dynamically uniform) broadcast index.
  • OpGroupNonUniformQuadBroadcast does as well, but we do not currently support the GroupNonUniformQuad capability.

Deprecations

• OpLessOrGreater is deprecated, use OpFOrdNotEqual instead.

Possible Support

The following SPIR-V 1.5 capabilities do not directly imply 'Shader', but I recommend that we do not require them:

Operand kind Capability: VulkanMemoryModel
Operand kind Capability: VulkanMemoryModelDeviceScope

• VulkanMemoryModel (not supporting)
• VulkanMemoryModelDeviceScope (only relevant with VulkanMemoryModel)

Operand kind Capability: ShaderLayer
Operand kind Capability: ShaderViewportIndex

• ShaderLayer (only relevant for Vertex or Tessellation execution models)
• ShaderViewportIndex (only relevant for Vertex or Tessellation execution models)

Operand kind Capability: StorageBuffer8BitAccess
Operand kind Capability: UniformAndStorageBuffer8BitAccess
  Requires Capabilities: ['StorageBuffer8BitAccess']
Operand kind Capability: StoragePushConstant8

• StorageBuffer8BitAccess (requires StorageBuffer storage class -> Shader)
• UniformAndStorageBuffer8BitAccess (requires StorageBuffer8BitAccess)
• StoragePushConstant8 (requires PushConstant storage class -> Shader)

Operand kind Capability: UniformTexelBufferArrayDynamicIndexing
  Requires Capabilities: ['SampledBuffer']
Operand kind Capability: StorageTexelBufferArrayDynamicIndexing
  Requires Capabilities: ['ImageBuffer']

• UniformTexelBufferArrayDynamicIndexing (not supporting any forms of dynamic indexing)
• StorageTexelBufferArrayDynamicIndexing (requires ImageBuffer, which enables OpTypeImage with Sampled == 2)
