Hi,
I have a proposal to add new constants to the memory_order enum:
memory_order_hle = 16, memory_order_hle_acquire = memory_order_hle | memory_order_acquire, memory_order_hle_release = memory_order_hle | memory_order_release
These constants can be used to support Intel HLE (Hardware Lock Elision) [1] in Boost.Atomic and then reused by Boost.Sync. [...]
I have no objections. If you make a pull request I'll merge it.
BTW, maybe Boost.Atomic is a better place for memory_order.hpp?
It is. It was intended to go there. Problem was, when Boost.Atomic finally landed, I didn't want to make shared_ptr depend on it. It now however occurs to me that shared_ptr doesn't actually use the memory order argument. So I can just make the functions take "int" and avoid the #include. We can then move <boost/memory_order.hpp> to Boost.Atomic.
