- * Contemporary compilers implement lock-free atomic memory access
- * primitives that facilitate writing "thread-opportunistic" or even real
- * multi-threading low-overhead code. "Thread-opportunistic" is when
- * exact result is not required, e.g. some statistics, or execution flow
- * doesn't have to be unambiguous. Simplest example is lazy "constant"
- * initialization when one can synchronize on variable itself, e.g.
- *
- * if (var == NOT_YET_INITIALIZED)
- *     var = function_returning_same_value();
- *
- * This does work provided that loads and stores are single-instruction
- * operations (and integer ones are on *all* supported platforms), but
- * it upsets Thread Sanitizer. Suggested solution is
- *
- * if (tsan_load(&var) == NOT_YET_INITIALIZED)
- *     tsan_store(&var, function_returning_same_value());
- *
- * Production machine code would be the same, so one can wonder why
- * bother. Having Thread Sanitizer accept "thread-opportunistic" code
- * allows to move on trouble-shooting real bugs.
- *
- * Resolving Thread Sanitizer nits was the initial purpose for this module,
- * but it was later extended with more nuanced primitives that are useful
- * even in "non-opportunistic" scenarios. Most notably verifying if a shared
- * structure is fully initialized and bypassing the initialization lock.
- * It's suggested to view macros defined in this module as "annotations" for
- * thread-safe lock-free code, "Thread-Safe ANnotations"...
- *
- * It's assumed that ATOMIC_{LONG|INT}_LOCK_FREE are assigned same value as
- * ATOMIC_POINTER_LOCK_FREE. And check for >= 2 ensures that corresponding
- * code is inlined. It should be noted that statistics counters become
- * accurate in such case.
- *
- * Special note about TSAN_QUALIFIER. It might be undesired to use it in
- * a shared header. Because whether operation on specific variable or member
- * is atomic or not might be irrelevant in other modules. In such case one
- * can use TSAN_QUALIFIER in cast specifically when it has to count.

- * There is subtle dependency on /volatile:<iso|ms> command-line option.
- * "ms" implies same semantic as memory_order_acquire for loads and
- * memory_order_release for stores, while "iso" - memory_order_relaxed for
- * either. Real complication is that defaults are different on x86 and ARM.
- * There is explanation for that, "ms" is backward compatible with earlier
