J.3.5 Integers
Any extended integer types that exist in the implementation (6.2.5).
Whether signed integer types are represented using sign and magnitude, two’s complement, or ones’ complement, and whether the extraordinary value is a trap representation or an ordinary value (6.2.6.2).
The rank of any extended integer type relative to another extended integer type with the same precision (6.3.1.1).
The result of, or the signal raised by, converting an integer to a signed integer type when the value cannot be represented in an object of that type (6.3.1.3).
The results of some bitwise operations on signed integers (6.5).
