vec_ternarylogic

Purpose

Performs one of the 256 logical operations on three input vectors to produce the output vector.

Note: This built-in function is valid only when the -mcpu option is set to target Power10 processors.

Syntax

d=vec_ternarylogic(a,b,c,e)

Result and argument types

The following table describes the types of the returned value and the function arguments.

Table 1. Result and argument types
d	a	b	c	e
vector unsigned char	vector unsigned char	vector unsigned char	vector unsigned char	const unsigned int
vector unsigned short	vector unsigned short	vector unsigned short	vector unsigned short	const unsigned int
vector unsigned int	vector unsigned int	vector unsigned int	vector unsigned int	const unsigned int
vector unsigned long long	vector unsigned long long	vector unsigned long long	vector unsigned long long	const unsigned int

Note: e must have a value between 0 and 255, inclusive.

Result value

For each integer value i from 0 to 127, let j be the value of the concatenation of the contents of bit i of a, b, and c. The value of bit j of the 8-bit value in e is placed into bit i of d.
