QDataStream: inline floatingPointPrecision()
There is a 2-byte padding in all architectures between the noswap member
and byteorder, because the latter requires a 32-bit alignment. So we can
use this space to store this little-used field and avoid one more reason
for QDataStreamPrivate.
Now:
class QScopedPointer<QDataStreamPrivate> d; /* 0 8 */
class QIODevice * dev; /* 8 8 */
bool owndev; /* 16 1 */
bool noswap; /* 17 1 */
quint8 fpPrecision; /* 18 1 */
/* XXX 1 byte hole, try to pack */
enum ByteOrder byteorder; /* 20 4 */
int ver; /* 24 4 */
enum Status q_status; /* 28 4 */
/* size: 32, cachelines: 1, members: 9 */
