Do you think you can just write this :
 
void * memmove(void * s1, const void  * s2, size_t n)
{
return memmove(s1, s2, n);
}
 
in your library's source?

 
      .global memmove
memmove:
      MM     R2,R1,R3
      RET
 
sure !
 

Can R3 be a const, that causes issues for restartability, but branch
prediction is easier and the code is shorter.

Though I guess forwarding a const is probably a thing today to improve
branch prediction, which is normally HORRIBLE for short branch counts.
