pub fn prefetch_bit4_rows(rows: &[Bit4Row<'_>])Expand description
Prefetches caller-selected packed rows into L1 for a later gather group.
Traversal can call this only for degrees where M0 found a benefit (R >= 32), leaving small-degree scoring unchanged. Every validated row handle supplies a live readable address. This is a no-op on non-AArch64 targets.
