Question

What are the two major types of branchless logic code emitted by popular compilers?

a.

Arithmetic-based and conditional-based

b.

Loop-based and array-based

c.

Register-based and memory-based

d.

Stack-based and queue-based

Posted under Reverse Engineering

Answer: (a).Arithmetic-based and conditional-based Explanation:The two major types of branchless logic code emitted by popular compilers are arithmetic-based and conditional-based. The arithmetic-based approach converts logic into a purely arithmetic sequence that provides the same end result as the original high-level language logic. The conditional-based approach employs special conditional instructions (when available on the target CPU) to eliminate or reduce the number of jumps required in order to implement logic.
