   Clever architects put the byte swap it in the load and store   
   instructions, where the byte-swapping is just an addition to the   
   handling of misaligned loads and stores, which itself is an addition   
   to the handling of smaller-than-transfer-width accesses.  PowerPC has   
   such instructions.
