 There's also, somewhat separately, the possibility to lower ``ATOMIC_FENCE`` to
 ``__sync_synchronize()``. This may happen or not happen independent of all the
 above, controlled purely by ``setOperationAction(ISD::ATOMIC_FENCE, ...)``.
+
+On AArch64, a variant of the __sync_* routines is used which contain the memory
+order as part of the function name. These routines may determine at runtime
+whether the single-instruction atomic operations which were introduced as part
+of AArch64 Large System Extensions "LSE" instruction set are available, or if
+it needs to fall back to an LL/SC loop. The following helper functions are
+implemented in both ``compiler-rt`` and ``libgcc`` libraries
+(``N`` is one of 1, 2, 4, 8, and ``M`` is one of 1, 2, 4, 8 and 16, and
+``ORDER`` is one of 'relax', 'acq', 'rel', 'acq_rel')::
+
+  iM __aarch64_casM_ORDER(iM expected, iM desired, iM *ptr)
+  iN __aarch64_swpN_ORDER(iN val, iN *ptr)
+  iN __aarch64_ldaddN_ORDER(iN val, iN *ptr)
+  iN __aarch64_ldclrN_ORDER(iN val, iN *ptr)
+  iN __aarch64_ldeorN_ORDER(iN val, iN *ptr)
+  iN __aarch64_ldsetN_ORDER(iN val, iN *ptr)
+
+Please note, if LSE instruction set is specified for AArch64 target then
+out-of-line atomics calls are not generated and single-instruction atomic
+operations are used in place.
