Well, it doesn't.  It has some support for driver (i.e. kernel) developers,
but none for application developers.  And even the driver interfaces
include delightful statements like:

    there are no guarantees that this function will not be reordered on non
    x86 architectures, so if you are writing portable code, make sure not
    to rely on its reordering guarantees.
