vec_slv
Purpose
Left shifts the elements of a given vector by a given number of bits.
Note: This built-in function
is valid only when the -mcpu option is set to target POWER9 processors
or higher.
Syntax
d=vec_slv(a, b)Result and argument types
The result and arguments are all of the vector unsigned char type.
Result value
Suppose the following information. Element i of the result vector contains the
same bit string as bit Si - bit Si+7 of
Xi.
- Si (0<=i<=15) denotes the value in the three
least-significant bits of element i of
b. - Xi (0<=i<=14) denotes the halfword formed by concatenating
elements i and i+1 of
a. - X15 denotes the halfword formed by concatenating element 15 of
aand a zero byte.
