## 128-bit SVE

For each signed 32-bit integer, set (4) as shown, given f(x,y) = ((x << 31) + y + 0x40000000) >> 31, with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the pair of values used from (1) is specified by `imm`

.

## 256-bit SVE

For each signed 32-bit integer, set (4) as shown, given f(x,y) = ((x << 31) + y + 0x40000000) >> 31, with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the pair of values used from (1) is specified by `imm`

.

## 512-bit SVE

For each signed 32-bit integer, set (4) as shown, given f(x,y) = ((x << 31) + y + 0x40000000) >> 31, with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the pair of values used from (1) is specified by `imm`
