GB-128 33.5 [atomic] Add minimum and maximum atomic operations #450

Closed wg21bot closed 1 year ago

wg21bot commented 1 year ago

Atomic minimum and maximum operations have widespread support in hardware and yet are missing from the C++ standard. A proposal to add them was approved by Library Evolution for C++23 in 2021, however since it has been consistently deprioritized in the Library Working Group due to other, more urgent work.

Adopt P0493 which adds fetch_min / fetch_max atomic operations.
