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

§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.
