Multiplication Overflow of Size

Subtraction Underflow of Size

Could detect violations of this recommendation by flagging any comparison expression involving addition that could potentially overflow. For example, instead of comparing a + b < c (where b and c are compile-time constants) and b > c, the code should compare a < c - b. (This assumes a, b, c are unsigned ints. Usually b is small and c is an upper bound such as INT_MAX.)
