-	// 16-bit signed division. Most of the special cases are dealt
-	// with by the 15-bit signed division library (e.g., division by
-	// zero, division by 1, and so on). This wrapper simply inverts	
-	// any negative inputs, calls the 15-bit library, and flips any
-	// results as necessary.  The
-	// only special cases to be handled here are where either the 
-	// divisor or the dividend are the maximum negative values.
-
-	// Encode r5 with a bit pattern which indicates whether the
-	// outputs of the division must be negated. The MSB will be set
-	// to the sign of the dividend (which controls the remainder's
-	// sign), while the LSB will store the XOR of the two signs,
-	// which indicates the quotient's sign. R5 is not modified by the
-	// 15-bit divmod routine.
