strcpy implementations

[Cesar Quiroz]

Are there any implementations that don't copy left-to-right?  I
would expect the IBM version to do block moves (mvcl?) and I think
the amd29000-in-word-mode version has also been discussed in this
forum.  These methods don't follow the byte-at-a-time idiom
                            *p++ = *q++
but still keep some semblance of left-to-rightness.
Does anyone know of a widely used implementation that goes
right-to-left?
