What are some common compiler optimization techniques?

What are some common compiler optimization techniques?

Common compiler optimization techniques include inlining, loop unrolling, constant folding, and dead code elimination.

Can you explain loop unrolling in more detail?

Loop unrolling is an optimization technique that reduces the overhead of loop control by increasing the number of operations performed within the loop body.

What are the benefits of using constant folding?

Constant folding improves performance by evaluating constant expressions at compile time rather than at runtime, reducing computation.

Are there any downsides to these optimizations?

Yes, some downsides include increased binary size and potential cache inefficiencies, which can affect performance negatively.

How do these techniques impact runtime performance?

These techniques can significantly improve runtime performance by reducing execution time and resource usage, but their effectiveness varies by context.
