9.6 Bit-fields [class.bit]
1 A member-declarator of the form
identifieropt : constant-expression
specifies a bit-field; its length is set off from the bit-field name by a colon. The bit-field attribute is not part
of the type of the class member. The constant-expression shall be an integral constant-expression with a
value greater than or equal to zero. The constant-expression may be larger than the number of bits in the
object representation (3.9) of the bit-field’s type; in such cases the extra bits are used as padding bits and do
not participate in the value representation (3.9) of the bit-field. Allocation of bit-fields within a class object
is implementation-defined. Alignment of bit-fields is implementation-defined. Bit-fields are packed into
some addressable allocation unit. [Note: bit-fields straddle allocation units on some machines and not on
others. Bit-fields are assigned right-to-left on some machines, left-to-right on others. ]
