SPIR-V 1.6 Testing

[bashbaug]

Here is one more issue to track SPIR-V 1.6 testing.

• New Behavior:

  • Adds a new Nontemporal image operand.
  • The FP Fast Math Mode can apply to many more instructions:
    • OpFNegate
    • Comparison instructions such as OpOrdered, OpUnordered, OpFOrdEqual, etc.
    • Extended instructions - TBD, which ones?
  • Adds the UniformDecoration capability, and Uniform and UniformId decorations.
  • DotProduct and associated instructions may now be available without SPV_KHR_integer_dot_product.
  • "NonSemantic" extended instruction sets are available. Not defining a task for this, because it should probably be tested as part of the non-semantic instruction set itself.

• Restrictions (informational):

  • OpTypeSampledImage and OpSampledImage do not work on Buffer images.
  • OpBranchConditional cannot have the same id for the True Lable and False Label.
