Memory Barriers Are Like Source Control Operations

用 VCS 来类比四种 memory fence

Acquire and Release Semantics

C++ provides acquire and release semantics, which are in fact founded on barriers.

acquire semantcis: #LoadLoad and #LoadStore; apply to read operations.

Acquire semantics prevent memory reordering of the read-acquire with any read or write operation that follows it in program order.

release sematncis: #StoreStore and #LoadStore; apply to write operations.

Release semantics prevent memory reordering of the write-release with any read or write operation that precedes it in program order.
