14 // This file illustrates how padding is handled: alignment
15 // requirements can lead to the introduction of padding, either before
16 // fields or at the end of the structure as a whole.
18 // It avoids using u64/i64 because on some targets that is only 4-byte
19 // aligned (while on most it is 8-byte aligned) and so the resulting
20 // padding and overall computed sizes can be quite different.
