In order to deprecate the rte_atomic and rte_smp barrier APIs [1], prevent the patches from using these APIs and __sync builtins in new code. Please use __atomic builtins instead of __sync builtins, rte_atomicNN_xxx and rte_smp_[r/w]mb APIs. On x86 the __atomic_thread_fence(__ATOMIC_SEQ_CST) is quite expensive for SMP case. Flag the new code which use __atomic_thread_fence API. Please use rte_thread_fence API instead of __atomic_thread_fence builtins. 1: Refer to the locks-and-atomic-operations section in https://doc.dpdk.org/guides/prog_guide/writing_efficient_code.html Signed-off-by: Phil Yang <phil.yang@arm.com> Reviewed-by: Ruifeng Wang <ruifeng.wang@arm.com>
