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). In particular, note that vnum is scaled by the vector length, VL, which is not known at compile time.
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.
