128-bit SVE
For each 32-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 32.
256-bit SVE
For each 32-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 32.
512-bit SVE
For each 32-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 32.
Larger sizes
1024-bit SVE
For each 32-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 32.
2048-bit SVE
For each 32-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 32.
