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

IA-32, IntelŪ EM64T, IntelŪ ItaniumŪ architecture
| Linux and Mac OS: | -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 and Mac OS: -funroll-loops
Windows: /unroll:n
