SPLICE: Splice two vectors under predicate control

128-bit SVE

Take the contiguous 8-bit lanes from (2), between the first and last corresponding set predicate bits in (1) (inclusive), and move them to the low lanes of (4). Any remaining high lanes in (4) are filled with the low elements from (3).

256-bit SVE

Take the contiguous 8-bit lanes from (2), between the first and last corresponding set predicate bits in (1) (inclusive), and move them to the low lanes of (4). Any remaining high lanes in (4) are filled with the low elements from (3).

512-bit SVE

Take the contiguous 8-bit lanes from (2), between the first and last corresponding set predicate bits in (1) (inclusive), and move them to the low lanes of (4). Any remaining high lanes in (4) are filled with the low elements from (3).

Larger sizes

1024-bit SVE

Take the contiguous 8-bit lanes from (2), between the first and last corresponding set predicate bits in (1) (inclusive), and move them to the low lanes of (4). Any remaining high lanes in (4) are filled with the low elements from (3).

2048-bit SVE

Take the contiguous 8-bit lanes from (2), between the first and last corresponding set predicate bits in (1) (inclusive), and move them to the low lanes of (4). Any remaining high lanes in (4) are filled with the low elements from (3).
