A library for atomic operations (development files)
Libatomic-ops implements a large collection of operations, each one of which is a combination of an (optional) atomic memory operation, and a memory barrier. It also implements associated feature-test macros that determine whether a particular operation is available on the current target hardware (either directly or by synthesis). Libatomic-ops attempts to replace various existing files with similar goals, since they usually do not handle differences in memory barrier styles with sufficient generality.
This package provides the header files and documentation needed by developers.
