Question

Why do optimizers convert pretested loops to posttested loops?

a.

To make them more efficient

b.

To make them easier to understand

c.

To make them smaller in size

d.

To make them faster to execute

Posted under Reverse Engineering

Answer: (a).To make them more efficient Explanation:Optimizers convert pretested loops to posttested loops to make them more efficient. Pretested loops require an extra unconditional jump at the end of the loop's body, which makes them less efficient than posttested loops.
