llvm dev - Feb 2020 - Can I delete a function argument and its corresponding code from a file

I have a following sample function in a file which contains only function
definitions like this.

void mul(int x, int y, int& out, *int* arr*) {
 * arr[0] = 2;*
*  arr[1] = 1;*
  out = x * y;
}

I want to convert it to
void mul(int x, int y, int& out) {
  out = x * y;
}

file contains only above function definitions.

Thanks & Regards
Jeevan

Hi Jeevan,

the function is externally visible, you cannot modify the signature.
If it has internal or private linkage you can, assuming you adjust all
the uses (call sites and other uses).

Cheers,
  Johannes

Thank you for the clarification.
