Safety

• pointer::offset safety constraints must be met for the address calculation for each active element (governed by pg).
• This dereferences and accesses the calculated address for each active element (governed by pg).
• Non-temporal accesses have special memory ordering rules, and explicit barriers may be required for some applications.
