 > [!NOTE]
 > The alignment is usually the same for a given bit width. However, on some targets such as 32-bit x86, 64-bit atomic types such as [`AtomicI64`][core::sync::atomic::AtomicI64] have an alignment of 8 bytes while `i64` is only aligned to 4 bytes. In this situation, `target_has_atomic_primitive_alignment = "64"` is not set.
