  47          Allows turn on optimalized library function (memcpy and memmove).
  48          They are optimized by using word alignment. This will work
  49          fine if both source and destination are aligned on the same
  50          boundary. However, if they are aligned on different boundaries
  51          shifts will be necessary. This might result in bad performance
  52          on MicroBlaze systems without a barrel shifter.
