If the current calling convection CurCC is not equal to Target calling 
convection ToCC and current calling convention (CurCC) is equal to the 
default calling convention (DefaultCC), that means DefaultCC can not be 
equal to ToCC so the right part of the expression DefaultCC == ToCC is 
not needed.

revelant code -

  if (CurCC == ToCC)
    return;
  if (CurCC != DefaultCC || DefaultCC == ToCC)
    return;
