+ * If dst and src are 4 byte aligned, copy 8 bytes at a time.
+ * If the src is 4, but not 8 byte aligned, we first read 4 bytes to get
+ * it 8 byte aligned.  Thus, we can do a little read-ahead, without
+ * dereferencing a cache line that we should not touch.
+ * Note that short and long instructions have been scheduled to avoid
+ * branch stalls.
+ * The beq_s to r3z could be made unaligned & long to avoid a stall
+ * there, but it is not likely to be taken often, and it would also be likely
+ * to cost an unaligned mispredict at the next call.
