I have a function with a loop that I would get the extended development of the loop in c++ code. Also I have a recursive function that I wanted to get the same.
An example of I need:
for (i = 0; i <4; i++)
{
printf ("%d", "example");
}
should result that i need
printf ("%d", "example");
printf ("%d", "example");
printf ("%d", "example");
printf ("%d", "example");
this is a simple example. But I would need to do this for more complex functions.
For what it's worth I use visual c++
.
I do not know if there is a build option for this.
Visual C++ does not have an explicit option for loop unrolling. However, if you turn optimisations on, then the optimiser loop unrolls based on heuristic. Loop unrolling is a trade-off - it may or may not result in improved performance.
Here is a discussion on loop unrolling in Visual C++.
