[PATCH v11 0/5] MR225: vkd3d-shader/tpf: Read complete swizzle/mask info from parameter tokens.
-- v11: vkd3d-shader/tpf: Handle the swizzle type bitfield in dst param tokens. vkd3d-shader/tpf: Handle the dimension bitfield in dst param tokens. vkd3d-shader/tpf: Use the default vec4 swizzle if a src param contains a mask. vkd3d-shader/tpf: Handle the dimension bitfield in src param tokens. vkd3d-shader/spirv: Emit an error if a case value is not a constant.

Should it have been validated earlier though? I.e., can a valid shader cause us to get here, or is this necessarily the result of invalid vsir produced from invalid tpf or d3dbc?
