-	We can discard the first three lines marked "X" since we produce
-	only a 64 bit result.  So, we need ten 16-bit multiplies.
-
-	Individual mul-acc results:
-[E1]	 =  R1.h * R2.l + R3.h * R0.l + R1.l * R2.h + R3.l * R0.h
-[E2]	 =  R1.l * R2.l + R3.l * R0.l + R0.h * R2.h
-[E3]	 =  R0.l * R2.h + R2.l * R0.h
-[E4]	 =  R0.l * R2.l
-
-	We also need to add high parts from lower-level results to higher ones:
-	E[n]c = E[n] + (E[n+1]c >> 16), where E4c := E4
-
-	One interesting property is that all parts of the result that depend
-	on the sign of the multiplication are discarded.  Those would be the
-	multiplications involving R1.h and R3.h, but only the top 16 bit of
-	the 32 bit result depend on the sign, and since R1.h and R3.h only
-	occur in E1, the top half of these results is cut off.
-	So, we can just use FU mode for all of the 16-bit multiplies, and
-	ignore questions of when to use mixed mode.  */
