Your question is Compiler Optimization Levels Impact. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the impact of compiler optimization levels on your code. Compare common levels like -O0, -O1, -O2, -O3, and -Os, and discuss the trade-offs for performance, memory, and debugging in embedded systems.
