Hi!, I'm working on a compiler plugin in backend IR where I'm in need to move some statements from a user generated function to a plugin generated one. When I move the statements using IrElement.deepCopyWithSymbol I can properly clone the entire tree I need but this tree comes with proper offsets that I need to reset to UNDEFINED_OFFSET . I tried recursively walking the tree and mutating it but offsets are declared as a val and passed as arguments to most methods in irFactory .

Is there a way to change the offsets of an existing IR Tree?
Is there a way to clone a tree without the offsets?

Thanks!

deepCopyWithSymbols accepts createCopier as the last parameter. By default, it creates DeepCopyIrTreeWithSymbols, but in your case, you should implement your own copier, which will be similar to DeepCopyIrTreeWithSymbols, but resetting offsets.

Thanks @Ilmir Usmanov [JB], I worked around it by not transferring the statements and making a delegated call to the original function containing the statements, but I will use that next time I'm in need of this. :)
