VINSERT

Operation

Replaces one indexed vector lane with an integer scalar value.

VECTOR

VINSERT interprets the scalar index as unsigned and replaces only that lane of Vd. The B, W, L, and Q forms use the corresponding low field of Rn. Every lane at another index retains its previous value.

An index at or above the selected vector element count raises VECTOR_LANE_INDEX_OUT_OF_RANGE. The faulting instruction commits no destination change.

The scalar value x replaces Vd lane i, and every other lane retains its old destination value.
