CLZ Zd.B, Pg/Z, Zn.B (SVE2.2 (SME2.2
128-bit SVE
For each 8-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 8.
256-bit SVE
For each 8-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 8.
512-bit SVE
For each 8-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 8.
