Tells the compiler the maximum number of times to unroll loops.

| Linux: | -unroll[n] |
| Windows: | /Qunroll[:n] |
| n | Is the maximum number of times a loop can be unrolled.
To disable loop enrolling, specify 0. On ItaniumŪ-based processors, you can only specify a value of 0. |
| -unroll or /Qunroll |
The compiler uses default heuristics when unrolling loops. |
This option tells the compiler the maximum number of times to unroll loops.
If you do not specify n, the optimizer determines how many times loops can be unrolled.
Linux: -funroll-loops
Windows: /unroll:n
