ABSTRACT:
An arrangement is provided for improving the performance of a dynamic compiler, specifically for dynamically optimizing integer division operations. When a compiler receives an integer division code at runtime, the compiler dynamically profiles a divisor of the division code. The integer division code is then optimized based on the characteristics of the divisor, which are determined at runtime.
