inline VisualC++

I remember having read somewhere that VisualC++ does not inline a funtion as soon as a loop is in there or an if statement.
But i cant find the documentation about that anymore, anybody knows these rules or where to find them?

That's not true.
It inlines this just fine:

Code:

#include <iostream>

void test()
{
    for (int i = 0; i < 10; i++)
        std::cout << "Hello World!\n";
}


int main ()
{
    test();
}

No doubt the decision as to whether to inline or not depends on many factors.

To mention a couple which Elysia's example does not show:
- a loop where the number of iterations is not known at compile time might not be inlined.
- a loop body consisting of many statements might not be inlined.

Inlining works best when the cost of calling the function becomes significant in the total amount of work done. So a simple function performing an assignment would be ideal. Inlining an entire sort function is unlikely to make much of a difference (except to bloat the code).

I don't think it's a simple rule as to whether to inline or not. The following is still inlined:

Code:

#include <iostream>

void test(int n)
{
    for (int i = 0; i < n; i++)
        std::cout << "Hello World!\n";
}


int main ()
{
    int n;
    std::cout << "Enter num loops: ";
    std::cin >> n;
    test(n);
}

Compilers are probably smarter than this.

it seems the documentation I was looking for is outdated now and that VisualC++ has cost/benefit analyzing code now that decides if something is inlined.
