They went through several places where arithmetic overflow could conceivably happen, deciding on a case-by-case basis whether the external constraints on the data would justify omitting the check. They did this in order to free up processor cycles to get the duty cycle velow a prescribed maximum. You may look at that through Ada- colored glasses if you like and call it still leaving it to the compiler.
