### §Safety

- `pointer::offset` safety constraints must be met for the address calculation for each active element (governed by `pg`, the first-fault register (`FFR`) and first-faulting behaviour).
- This dereferences and accesses the calculated address for each active element (governed by `pg`, the first-fault register (`FFR`) and first-faulting behaviour).
- Result lanes corresponding to inactive FFR lanes (either before or as a result of this intrinsic) have “CONSTRAINED UNPREDICTABLE” values, irrespective of predication. Refer to architectural documentation for details.
