128-bit SVE
For each odd signed 32-bit integer set the double-width (3) to (1) * (2) << 1, with signed saturation to 0x7FFFFFFFFFFFFFFF. Within each 128-bit segment, the value used from (1) is specified by imm.
256-bit SVE
For each odd signed 32-bit integer set the double-width (3) to (1) * (2) << 1, with signed saturation to 0x7FFFFFFFFFFFFFFF. Within each 128-bit segment, the value used from (1) is specified by imm.
512-bit SVE
For each odd signed 32-bit integer set the double-width (3) to (1) * (2) << 1, with signed saturation to 0x7FFFFFFFFFFFFFFF. Within each 128-bit segment, the value used from (1) is specified by imm.
