svuint16_t svclz[_u16]_m(svuint16_t inactive, svbool_t pg, svuint16_t op)
128-bit SVE
For each 16-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 16.
256-bit SVE
For each 16-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 16.
512-bit SVE
For each 16-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 16.
Larger sizes
1024-bit SVE
For each 16-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 16.
2048-bit SVE
For each 16-bit integer set (2) to the number of leading zero bits in (1). If (1) is zero, the result is 16.
