128-bit SVE
For each 16-bit integer set (3) to ( (2) << const ) | ( (1) & ~( 0xFFFF << const ) ). This preserves the const least-significant bits from (1), while inserting the ( 16 − const ) least-significant bits from (2) into the most-significant bits of (3). The shift amount is limited to 0 ≤ const ≤ 15.
256-bit SVE
For each 16-bit integer set (3) to ( (2) << const ) | ( (1) & ~( 0xFFFF << const ) ). This preserves the const least-significant bits from (1), while inserting the ( 16 − const ) least-significant bits from (2) into the most-significant bits of (3). The shift amount is limited to 0 ≤ const ≤ 15.
512-bit SVE
For each 16-bit integer set (3) to ( (2) << const ) | ( (1) & ~( 0xFFFF << const ) ). This preserves the const least-significant bits from (1), while inserting the ( 16 − const ) least-significant bits from (2) into the most-significant bits of (3). The shift amount is limited to 0 ≤ const ≤ 15.

1024-bit SVE
For each 16-bit integer set (3) to ( (2) << const ) | ( (1) & ~( 0xFFFF << const ) ). This preserves the const least-significant bits from (1), while inserting the ( 16 − const ) least-significant bits from (2) into the most-significant bits of (3). The shift amount is limited to 0 ≤ const ≤ 15.
2048-bit SVE
For each 16-bit integer set (3) to ( (2) << const ) | ( (1) & ~( 0xFFFF << const ) ). This preserves the const least-significant bits from (1), while inserting the ( 16 − const ) least-significant bits from (2) into the most-significant bits of (3). The shift amount is limited to 0 ≤ const ≤ 15.
