Question

In the context of code optimization, "Loop Invariant Code Motion" refers to:

• A. Removing loops that never execute.
• B. Moving computations that yield the same result regardless of the loop iteration outside the loop.
• C. Replacing expensive operations with cheaper ones inside a loop.
• D. Combining two loops into a single loop.

Hint:

To safely move a computation outside a loop, the compiler must ensure that the statement is not inside a conditional branch that might skip it, and that the variables involved are not modified anywhere within the loop body.

Answer 1

The Correct Option is B
