) Also, for lightly contended locks which can be utilized by unique threads, RTM can lower false cache line sharing, generally known as cache line ping-pong. This occurs when a number of threads from diverse processors are accessing unique methods, however the assets share the identical cache line. As a result, the processors continuously invalidate the cache lines of other processors, which forces them to study from major memory in lieu of their cache.
This use ends in conduct which mimics the behaviour of a final variable reference in Java. Against this, when applying const to your referenced details only, as in const SomeClass * ptr, the contents can't be modified (without having casting), however the reference itself can.
