🔬This is a nightly-only experimental API. (core_intrinsics)

This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).

Lowers in MIR to Rvalue::Aggregate with AggregateKind::RawPtr.

This is used to implement functions like slice::from_raw_parts_mut and ptr::from_raw_parts in a way compatible with the compiler being able to change the possible layouts of pointers.
