Datomic_bitops.txt5 While our bitmap_{}() functions are non-atomic, we have a number of operations
12 The single bit operations are:
18 RMW atomic operations without return value:
23 RMW atomic operations with return value:
33 All RMW atomic operations have a '__' prefixed variant which is non-atomic.
47 The test_and_{}_bit() operations return the original value of the bit.
55 - non-RMW operations are unordered;
57 - RMW operations that have no return value are unordered;
59 - RMW operations that have a return value are fully ordered.
