SwapSwapPosted Apr 2, 2013 20:31 UTC (Tue) by wahern (subscriber, #37304)In reply to: Swap by proski Parent article: A look at C++14: Papers Part 2
Are there any architectures where there exists an atomic, wait-free swap between two memory locations?
I suspect that they're uncommon if not non-existent.
In any event, presumably such an operation was left out of the stdatomic.h libraries for C11 and C++11 for a reason.
