+; The case will do aggressive interleave on PowerPC, resulting in a lot of memory checks.
+; (On the A2, always unroll aggressively. In fact, if aggressive interleaving is enabled,
+; similar issues may occur on other targets).
+; Interleaving should also be restricted by the threshold of memory checks similar to VF.
+; (e.g., runtime-memory-check-threshold, default 8).
