Hi,

boost:atomic<int>::is_lock_free() returns false on iPad 4 (armv7s) but returns true on iPad 3 (armv7). Is this expected or did I build boost incorrectly?

Most of Boost.Atomic code is header-only, so the problem is not related to building Boost. I suppose, noone added detection for the armv7s target because noone knows how to detect it at compile time. If you could provide a compiler predefined macro that can be used for this purpose, we could add the support.
