/*
 * Description: The ethread atomics API
 * Author: Rickard Green
 */

/*
 * This file maps native atomic implementations to ethread
 * API atomics. If no native atomic implementation
 * is available, a less efficient fallback is used instead.
 * The API consists of 32-bit size, word size (pointer size),
 * and double word size atomics.
 *
 * The following atomic operations are implemented for
 * 32-bit size, and word size atomics:
 * - cmpxchg
 * - xchg
 * - set
 * - init
 * - add_read
 * - read
 * - inc_read
 * - dec_read
 * - add
 * - inc
 * - dec
 * - read_band
 * - read_bor
 *
 * The following atomic operations are implemented for
 * double word size atomics:
 * - cmpxchg
 * - set
 * - read
 * - init
 *
 * Appart from a function implementing the atomic operation
 * with unspecified memory barrier semantics, there are
 * functions implementing each operation with the following
 * memory barrier semantics:
 * - rb (read barrier)
 * - wb (write barrier)
 * - acqb (acquire barrier)
 * - relb (release barrier)
 * - mb (full memory barrier)
 *
 * We implement all of these operation/barrier
 * combinations, regardless of whether they are useful
 * or not (some of them are useless).
 *
 * Double word size atomic functions are on the followning
 * form:
 *   ethr_dw_atomic_<OP>[_<BARRIER>]
 *
 * Word size atomic functions are on the followning
 * form:
 *   ethr_atomic_<OP>[_<BARRIER>]
 *
 * 32-bit size atomic functions are on the followning
 * form:
 *   ethr_atomic32_<OP>[_<BARRIER>]
 *
 * Apart from the operation/barrier functions
 * described above also 'addr' functions are implemented
 * which return the actual memory address used of the
 * atomic variable. The 'addr' functions have no barrier
 * versions.
 *
 * The native atomic implementation does not need to
 * implement all operation/barrier combinations.
 * Functions that have no native implementation will be
 * constructed from existing native functionality. These
 * functions will perform the wanted operation and will
 * produce sufficient memory barriers, but may
 * in some cases be less efficient than pure native
 * versions.
 *
 * When we create ethread API operation/barrier functions by
 * adding barriers before and after native operations it is
 * assumed that:
 * - A native read operation begins, and ends with a load.
 * - A native set operation begins, and ends with a store.
 * - An init operation begins with either a load, or a store,
 *   and ends with either a load, or a store.
 * - All other operations begins with a load, and ends with
 *   either a load, or a store.
 *
 * This is the minimum functionality that a native
 * implementation needs to provide:
 *
 * - Functions that need to be implemented:
 *
 *   - ethr_native_[dw_|su_dw_]atomic[BITS]_addr
 *   - ethr_native_[dw_|su_dw_]atomic[BITS]_cmpxchg[_<BARRIER>]
 *     (at least one cmpxchg of optional barrier)
 *
 * - Macros that needs to be defined:
 *
 *   A macro informing about the presence of the native
 *   implementation:
 *
 *   - ETHR_HAVE_NATIVE_[DW_|SU_DW_]ATOMIC[BITS]
 *
 *   A macro naming (a string constant) the implementation:
 *
 *   - ETHR_NATIVE_[DW_]ATOMIC[BITS]_IMPL
 *
 *   Each implemented native atomic function has to
 *   be accompanied by a defined macro on the following
 *   form informing about its presence:
 *
 *   - ETHR_HAVE_ETHR_NATIVE_[DW_|SU_DW_]ATOMIC[BITS]_<OP>[_<BARRIER>]
 *
 *   A (sparc-v9 style) membar macro:
 *
 *   - ETHR_MEMBAR(B)
 *
 *     Which takes a combination of the following macros
 *     or:ed (using |) together:
 *
 *     - ETHR_LoadLoad
 *     - ETHR_LoadStore
 *     - ETHR_StoreLoad
 *     - ETHR_StoreStore
 *
