128-bit SVE
For each signed 64-bit integer set the even 32-bit elements of (2) to (1) >> const, with unsigned saturation to 0 (if (1) is negative) or 0xFFFFFFFF, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 32.
256-bit SVE
For each signed 64-bit integer set the even 32-bit elements of (2) to (1) >> const, with unsigned saturation to 0 (if (1) is negative) or 0xFFFFFFFF, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 32.
512-bit SVE
For each signed 64-bit integer set the even 32-bit elements of (2) to (1) >> const, with unsigned saturation to 0 (if (1) is negative) or 0xFFFFFFFF, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 32.
