|
* Extracts a call to `target` inside the function identified by `labels`. Special parameters (`dispatch` and `extension`) are also handled.
|
|
*
|
|
* Examples are:
|
|
* ```
|
|
* this.<dispatchReceiver>.fn(this.<extensionReceiver>, param1, param2, param3, ...)
|
|
* param1.fn(this.<extensionReceiver>, param2, ...)
|
|
* param1.fn(param2, param3, ...)
|
|
* fn(this.<extensionReceiver>, param1, param2, ...)
|
|
* fn(param1, param2, ...)
|
|
* new MyType(param1, param2, ...)
|
|
* ```
|
|
*
|
|
* The parameters with default argument values cover special cases:
|
|
* - dispatchReceiverIdx is usually -1, except if a constructor is referenced
|
|
* - big arity function references need to call `invoke` with arguments received in an object array: `fn(param1[0] as T0, param1[1] as T1, ...)`
