unroll, Qunroll

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

Syntax

Linux and macOS:

-unroll[=n]

Windows:

/Qunroll[:n]

`n`	Is the maximum number of times a loop can be unrolled. To disable loop enrolling, specify 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.

Visual Studio: Optimization > Loop Unroll Count

Eclipse: None
