target/ppc: Fix lxvw4x, lxvh8x and lxvb16x
During the conversion these instructions were incorrectly treated as stores. We need to use set_cpu_vsr* and not get_cpu_vsr*. Fixes: 8b3b2d75c7c0 ("introduce get_cpu_vsr{l,h}() and set_cpu_vsr{l,h}() helpers for VSR register access") Signed-off-by: Anton Blanchard <anton@ozlabs.org> Reviewed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Tested-by: Greg Kurz <groug@kaod.org> Reviewed-by: Greg Kurz <groug@kaod.org> Message-Id: <20190524065345.25591-1-mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
