[PATCH v5 0/1] MR263: vkd3d-shader/spirv: Refactor the type system.

[Conor McCarthy (＠cmccarthy)]

Shader Model 6 introduces a 16-bit float (half) type, and 16-bit and 64-bit integer types. Storing extra info in the type enum simplifies checking if a type is any integer, floating point or numeric type, and the declaration of SPIR-V types. The benefits depend on using enum vkd3d_data_type in the backend instead of vkd3d_shader_component_type.

Patch 2 is difficult to split because types typically flow through to vkd3d_spirv_get_type_id(), so partial changes would require new calls to conversion functions which would be deleted again later.
