                Torbjorn Granlund and I will present
``Division by Invariant Integers using Multiplication'' at PLDI '94.
We give rules on how to compile expressions such as x/1994,
where x may be unsigned or signed and (in the signed case)
rounding may be towards zero or towards -infinity.


                One reviewer asks ``How common is division''?
Does anyone have recent statistics (static or dynamic)
about the frequency of integer division (quotient and/or remainder)?
How often is the divisor a constant? A power of 2?
