vec_xstw4

Purpose

Puts a 16-byte vector a to four 4-byte elements at the memory address specified by the displacement b and the pointer c.

This built-in function is valid only when -qarch is set to target POWER7 processors or higher.

Syntax

d=vec_xstw4(a, b, c)

Result value

This function adds the displacement and the pointer R-value to obtain the address for the store operation. It does not truncate the effective address to a multiple of 16 bytes.
