128-bit SVE
For each signed 64-bit integer set the odd 32-bit elements of (2) to (1) >> const, truncating with signed saturation to 0x7FFFFFFF or −0x80000000, preserving even elements. The shift amount is limited to 1 ≤ const ≤ 32.
256-bit SVE
For each signed 64-bit integer set the odd 32-bit elements of (2) to (1) >> const, truncating with signed saturation to 0x7FFFFFFF or −0x80000000, preserving even elements. The shift amount is limited to 1 ≤ const ≤ 32.
512-bit SVE
For each signed 64-bit integer set the odd 32-bit elements of (2) to (1) >> const, truncating with signed saturation to 0x7FFFFFFF or −0x80000000, preserving even elements. The shift amount is limited to 1 ≤ const ≤ 32.
