The primary takeaway from this experiment is that contemporary CPUs have direct guidance for atomic integer functions, for instance the LOCK prefix in x86, and std::atomic essentially exists as a transportable interface to People intructions: Exactly what does the "lock" instruction necessarily mean in x86 assembly? In aarch64, LDADD might be applied.
So to be able to apply the above mentioned three Directions within an atomic manner, we should always to start with get unique entry to the cacheline which is made up of the expected benefit. At the time we get exceptional accessibility, we should not relinquish exceptional accessibility on this cacheline until the "retail store" operation is done.
