svuint64_t svsbclb[_u64](svuint64_t op1, svuint64_t op2, svuint64_t op3)

## 128-bit SVE

Subtract-with-carry each pair of 64-bit integers from (2) and (3), using the carry bit from (1). Store the result, and the zero extended output carry bit, in (4).

## 256-bit SVE

Subtract-with-carry each pair of 64-bit integers from (2) and (3), using the carry bit from (1). Store the result, and the zero extended output carry bit, in (4).

## 512-bit SVE

Subtract-with-carry each pair of 64-bit integers from (2) and (3), using the carry bit from (1). Store the result, and the zero extended output carry bit, in (4).

## Larger sizes

## 1024-bit SVE

Subtract-with-carry each pair of 64-bit integers from (2) and (3), using the carry bit from (1). Store the result, and the zero extended output carry bit, in (4).

## 2048-bit SVE

Subtract-with-carry each pair of 64-bit integers from (2) and (3), using the carry bit from (1). Store the result, and the zero extended output carry bit, in (4).
