description="
Implementations for atomic memory.

libatomic_ops provides implementations for atomic memory update
operations on a number of architectures.  This allows direct use of
these in reasonably portable code.  Unlike earlier similar packages,
this one explicitly considers memory barrier semantics, and allows
the construction of code that involves minimum overhead across a
variety of architectures.
