It can be useful for compare-and-swap of values (typically pointers), for cas2 (double cas) function implementation which can be used in lock-free code.

It is implemented, but is missing from the list in the spec. Also cmpxchg8b is incorrectly written as cmpxch8b.

Spec bugs are 'websites' component
