Expand description

Load 32-bit data and sign-extend, first-faulting Arm’s documentation

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.
Addresses passed in bases lack provenance, so this is similar to using a usize as ptr cast (or core::ptr::with_exposed_provenance) on each lane before using it.
