What are some common optimization techniques used in C++ compilers?
Common optimization techniques include inlining, loop unrolling, constant folding, and dead code elimination.
Can you explain how loop unrolling works?
Loop unrolling is a technique where the loop's iterations are expanded to reduce the overhead of the loop control.
What impact does inlining have on performance?
Inlining can reduce function call overhead and enable further optimizations, but it may increase code size.
Are there any downsides to compiler optimizations?
Yes, aggressive optimizations can lead to longer compile times and may introduce bugs if not carefully managed.
