Examples for atomic - RMW functions that do not imply are memory barrier are e.g. add, + RMW functions that do not imply a memory barrier are e.g. add, subtract, (failed) conditional operations, _relaxed functions, but not atomic_read or atomic_set. A common example where a memory barrier may be required is when atomic ops are used for reference |
