Does Swift's ARC Utilize Objective-C ARC Intrinsics in LLVM?

In the LLVM Language Reference Manual, there is a section on Objective-C ARC Runtime Intrinsics. It seems to exist to handle ARC-related logic in LLVM IR.

I’m curious whether Swift’s ARC is also processed using these OBJC ARC Intrinsics, or if there is a separate one for Swift.

Does anyone know about this?
