Function* NewFunc,
Function const* OldFunc,
Instruction const* StartingInst,

| Name | Description |
|---|---|
| NewFunc | Destination function that receives the pruned clone. |
| OldFunc | Source function to clone from. |
| StartingInst | First instruction of OldFunc to begin cloning at. |
| VMap | Mapping from old values to new ones; updated during cloning. |
| ModuleLevelChanges | Whether module-level value remapping is allowed. |
| Returns | Filled with return instructions from the cloned body. |
| NameSuffix | Suffix appended to cloned value names. |
| CodeInfo | Collector for statistics about the cloned code. |
