I'm using both
delegatecall within an assembly block and i've noticed that when issuing a
call I need to provide 4 bytes (sig) + any arguments, whereas for
delegatecall I need to provide 4 bytes (sig) + 32 bytes of zeros and then my arguments.
Does anyone know why this is the case? Does it have something to do with using
delegatecall for libraries which expect the contract state to be the first argument?
