Question

How is the OR operator implemented in assembly language by some compilers like GCC?

a.

By using a single conditional jump for each condition.

b.

By using a conditional jump for the first condition and a non-conditional jump for the second condition.

c.

By using a conditional jump for the second condition and a non-conditional jump for the first condition.

d.

By using a conditional jump for each condition and adding a final jump that skips the conditional code block if neither conditions are met.

Answer: (d).By using a conditional jump for each condition and adding a final jump that skips the conditional code block if neither conditions are met. Explanation:The OR operator is implemented in assembly language by using a conditional jump for each condition and adding a final jump that skips the conditional code block if neither conditions are met. This approach is employed by GCC and several other compilers.
