Hi Yakov,
For cases 2) and 3) - CallInst is bound to the underlying function
type, to my knowledge. So you cannot modify the function type, but
instead you can create another CallInst with different function type
and replace original one with it. If you do not change the return
type, replaceAllUsesWith method would work. In attached code example
CallInst replacement logic is in lines 223-285.
HTH,
