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?
