vec_rl

Purpose

Rotates each element of a vector left by a given number of bits.

Syntax

d=vec_rl(a, b)

Result and argument types

The following tables describe the types of the returned value and the function arguments.

Table 1. Result and argument types
d	a	b
The same type as argument `a`	vector signed char	vector unsigned char
	vector unsigned char	vector unsigned char
	vector signed short	vector unsigned short
	vector unsigned short	vector unsigned short
	vector signed int	vector unsigned int
	vector unsigned int	vector unsigned int

Note: The following types are valid when the -mcpu option is set to target POWER8 processors, or higher.

Table 2. Result and argument types
d	a	b
The same type as argument `a`	vector signed long long	vector unsigned long long
The same type as argument `a`	vector unsigned long long	vector unsigned long long

Result value

Each element of the result is obtained by rotating the corresponding element of a left by the number of bits specified by the corresponding element of b.
