Marko Mäkelä	386f168ab3	MDEV-22456 after-merge fix: introduce Atomic_relaxed ... In the merge 9e6e43551f we made Atomic_counter a more generic wrapper of std::atomic so that dict_index_t would support the implicit assignment operator. It is better to revert the changes to Atomic_counter and instead introduce Atomic_relaxed as a generic wrapper to std::atomic. Unlike Atomic_counter, we will not define operator++, operator+= or similar, because we want to make the operations more explicit in the users of Atomic_wrapper, because unlike loads and stores, atomic read-modify-write operations always incur some overhead.	2020-05-18 15:02:55 +03:00
Marko Mäkelä	9e6e43551f	Merge 10.3 into 10.4 ... We will expose some more std::atomic internals in Atomic_counter, so that dict_index_t::lock will support the default assignment operator.	2020-05-16 07:39:15 +03:00
