vec_srl

Purpose

Right shifts a vector by a given number of bits.

Syntax

d=vec_srl(a,b)

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	b¹
The same type as argument `a`	vector bool char	Any of the following types: vector unsigned char vector unsigned short vector unsigned int
	vector signed char
	vector unsigned char
	vector bool short
	vector signed short
	vector unsigned short
	vector bool int
	vector signed int
	vector unsigned int
	vector pixel
	vector signed long long
	vector unsigned long long

Note:

The least significant three bits of all byte elements in b must be the same.

Result value

The result is produced by shifting the contents of a right by the number of bits specified by the last three bits of the last element of b. The bits that are shifted out are replaced by zeroes.
