128-bit SVE
For each signed 32-bit integer set (4) to ( ( (3) << 31 ) − (1) * (2) + 0x40000000 ) >> 31, with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the value used from (1) is specified by imm.
256-bit SVE
For each signed 32-bit integer set (4) to ( ( (3) << 31 ) − (1) * (2) + 0x40000000 ) >> 31, with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the value used from (1) is specified by imm.
512-bit SVE
For each signed 32-bit integer set (4) to ( ( (3) << 31 ) − (1) * (2) + 0x40000000 ) >> 31, with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the value used from (1) is specified by imm.
