Loop* L,

True if any induction-variable users were simplified.
| Name | Description |
|---|---|
| L | Loop whose induction-variable users may be simplified. |
| SE | ScalarEvolution used to analyze IV recurrences. |
| DT | Dominator tree used by simplification. |
| LI | Loop info for the function containing L. |
| TTI | Target transform info used for profitability checks. |
| Dead | Receives instructions that become dead and may be deleted. |
