vec_cntlz
Purpose
Computes the count of leading zero bits of each element of the input.
Syntax
d=vec_cntlz(a)Result and argument types
The following table describes the types of the returned value and the function arguments.
| d | a |
|---|---|
| vector unsigned char | vector unsigned char |
| vector unsigned char | vector signed char |
| vector unsigned short | vector unsigned short |
| vector unsigned short | vector signed short |
| vector unsigned int | vector unsigned int |
| vector unsigned int | vector signed int |
| vector unsigned long long | vector unsigned long long |
| vector unsigned long long | vector signed long long |
Result value
Each element of the result is set to the number of leading zeros of the corresponding element of a.
