vec_xl

Purpose

Loads a 16-byte vector from the memory address specified by the displacement a and the pointer b.

Syntax

d=vec_xl(a, b)

Result and argument types

The following tables describe the types of the function returned value and the function arguments in different bit modes.

Table 1. Data type of function returned value and arguments (in 32-bit mode)
d	a	b
vector signed char	int	const signed char *
vector unsigned char		const unsigned char *
vector signed short		const signed short *
vector unsigned short		const unsigned short *
vector signed int		const signed int *
vector unsigned int		const unsigned int *
vector signed long long		const signed long long *
vector unsigned long long		const unsigned long long *
vector float		const float *
vector double		const double *

Table 2. Data type of function returned value and arguments (in 64-bit mode)
d	a	b
vector signed char	long	const signed char *
vector unsigned char		const unsigned char *
vector signed short		const signed short *
vector unsigned short		const unsigned short *
vector signed int		const signed int *
vector unsigned int		const unsigned int *
vector signed long long		const signed long long *
vector unsigned long long		const unsigned long long *
vector float		const float *
vector double		const double *

Result value

vec_xl adds the displacement provided by a to the address provided by b to obtain the effective address for the load operation. It does not truncate the effective address to a multiple of 16 bytes.

The order of elements in the function result is different on little endian systems.
