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