--- Comment #1 from Jim Wilson <wilson at gcc dot gnu.org> ---
Most glibc targets already have an assembly language memcpy.S implementation. 
RISC-V should also.  This is likely the most effective solution to the problem. 
 We should fix the optimizer problem if possible of course.  It is just that
the glibc solution is likely easier than the gcc solution.
