## 128-bit SVE

Set each predicate bit in (3) corresponding to a 64-bit elements, from low to high, while (1) + *n* ≤ (2), with *n* starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.

(1), (2), and offsets computed from (1) are signed 32-bit integers.

## 256-bit SVE

Set each predicate bit in (3) corresponding to a 64-bit elements, from low to high, while (1) + *n* ≤ (2), with *n* starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.

(1), (2), and offsets computed from (1) are signed 32-bit integers.

## 512-bit SVE

Set each predicate bit in (3) corresponding to a 64-bit elements, from low to high, while (1) + *n* ≤ (2), with *n* starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.

(1), (2), and offsets computed from (1) are signed 32-bit integers.

## 1024-bit SVE

Set each predicate bit in (3) corresponding to a 64-bit elements, from low to high, while (1) + *n* ≤ (2), with *n* starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.

(1), (2), and offsets computed from (1) are signed 32-bit integers.

## 2048-bit SVE

Set each predicate bit in (3) corresponding to a 64-bit elements, from low to high, while (1) + *n* ≤ (2), with *n* starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.

(1), (2), and offsets computed from (1) are signed 32-bit integers.
