Orders both loads, and stores. No + * load or store is allowed to be reordered over the + * barrier. + * - ERTS_THR_WRITE_MEMORY_BARRIER + * Write barrier. Orders *only* stores.

Function prototypes are listed below. + * + * Each function implementing an atomic operation exist with the following + * implied memory barrier semantics. Not all combinations are useful, but + * all of them exist for simplicity. <B> is suffix in function name: + * + * - <B> - Description + * + * - mb - Full memory barrier. Orders both loads, and + * stores before, and after the atomic operation. + * No load or store is allowed to be reordered + * over the atomic operation. + * - relb - Release barrier. Orders both loads, and + * stores appearing *before* the atomic + * operation. These are not allowed to be + * reordered over the atomic operation. + * - acqb - Acquire barrier. Orders both loads, and stores + * appearing *after* the atomic operation. These + * are not allowed to be reordered over the + * atomic operation. + * - wb - Write barrier. Orders *only* stores. These are + * not allowed to be reordered over the barrier. + * Store in atomic operation is ordered *after* + * the barrier. + * - rb - Read barrier. Orders *only* loads. These are + * not allowed to be reordered over the barrier. + * Load in atomic operation is ordered *before* + * the barrier. + * - ddrb - Data dependency read barrier. Orders *only* + * loads according to data dependency across the + * barrier. Load in atomic operation is ordered + * before the barrier. + * + * If thread support has been disabled, these functions are mapped to + * functions that performs the same operation, but aren't atomic + * and don't imply any memory barriers. + * + * If the atomic operations are prefixed with erts_smp_ instead of only + * erts_ the atomic operations will only be atomic in the SMP enabled + * runtime system, and will be mapped to non-atomic operations without + * memory barriers in the runtime system without SMP support.
