// Defines a set of atomic integer operations that can be used as lightweight
// synchronization or as building blocks for heavier synchronization
// primitives. Their use is very subtle and requires detailed understanding of
// the behavior of supported architectures, so their direct use is not
// recommended except when rigorously deemed absolutely necessary for
// performance reasons.

// This file contains Starboard implementations for synchronization primitives
// used in ICU.
