How likely is it that a compiler can make use of string copy
instructions?  NEC's re-targeting of the portable C compiler to the 
V60 architecture frequently takes advantage of one of the V60's string 
copy instructions.  It uses a string copy for  structure assignments!  

Of course, these instructions are also used in the library routines.   
Another use that comes to mind is when loader zeros out a BSS area...
