![]() When a non constant memory model is passed to __atomic_* gcc falls back to seq_cst. This drops any HLE acquire or release bits. This can happen when <atomic> is used with -O0 as the member functions are not always inlined then and the memory argument passed in ends up being non-constant. v2: Use _GLIBCXX_ALWAYS_INLINE libstdc++-v3/: 2013-05-08 Andi Kleen <ak@linux.intel.com> PR target/55947 * libstdc++-v3/include/bits/atomic_base.h (_GLIBCXX_ALWAYS_INLINE): Add new macro.
