// This code uses cpp cl opt size to generate smaller code #includeint main() { std::cout << "Hello World!\n"; return 0; }
// This code uses cpp cl opt size and loop unrolling to generate smaller code #includeIn this example, we use the cpp cl opt size switch in conjunction with loop unrolling to generate smaller code. Loop unrolling is a technique where the loop body is duplicated multiple times to reduce the overhead of the loop control. The resulting executable file will be smaller than if we did not use these optimizations. Package/library: Microsoft Visual C++ Overall, the cpp cl opt size switch is a useful tool for optimizing code size in Microsoft Visual C++. It is particularly useful for embedded systems or when the code needs to be downloaded over slow networks.int main() { const int n = 10; int sum = 0; #pragma unroll for (int i = 0; i < n; ++i) { sum += i; } std::cout << "Sum is " << sum << "\n"; return 0; }
