What are some common compiler optimizations in C programming?
Common compiler optimizations in C include inlining functions, loop unrolling, constant folding, and dead code elimination.
How does loop unrolling improve performance?
Loop unrolling reduces the overhead of loop control by executing multiple iterations in a single loop pass, enhancing performance.
Are there any downsides to using aggressive optimizations?
Yes, aggressive optimizations can lead to increased binary size and may complicate debugging due to altered code structure.
Can I control optimizations in my C code?
Yes, you can control optimizations using compiler flags, such as -O1
, -O2
, or -O3
for different levels of optimization.
