-/* Return: the result of the comparison

-   Inputs:
-        in0:    dest (aka s1)
-        in1:    src  (aka s2)
-        in2:    byte count
-
-   In this form, it assumes little endian mode.  For big endian mode,
-   the two shifts in .l2 must be inverted:
-
-	shl   	tmp1[0] = r[1 + MEMLAT], sh1   // tmp1 = w0 << sh1
-	shr.u   tmp2[0] = r[0 + MEMLAT], sh2   // tmp2 = w1 >> sh2
