Question

What is the main goal of branchless logic optimization?

a.

To reduce the number of conditional jumps required for implementing a given logical statement.

b.

To increase the number of conditional jumps required for implementing a given logical statement.

c.

To make the code more readable and maintainable.

d.

To eliminate the need for arithmetic instructions.

Posted under Reverse Engineering

Answer: (a).To reduce the number of conditional jumps required for implementing a given logical statement. Explanation:The main goal of branchless logic optimization is to eliminate or at least reduce the number of conditional jumps required for implementing a given logical statement. This is done to improve the performance of the code by minimizing the number of times the processor has to refill its pipeline due to incorrect branch predictions.
