;   Updated align attritue from 16 to 8 to keep swap instructions tests.
;   Changes have been made on little-endian to use lvx and stvx
;   instructions instead of lxvd2x/xxswapd and xxswapd/stxvd2x for
;   aligned vectors with elements up to 4 bytes

; This test was generated from the following source:
;
; #define N 4096
; int ca[N] __attribute__((aligned(16)));
; int cb[N] __attribute__((aligned(16)));
; int cc[N] __attribute__((aligned(16)));
; int cd[N] __attribute__((aligned(16)));
;
; void foo ()
; {
;   int i;
;   for (i = 0; i < N; i++) {
;     ca[i] = (cb[i] + cc[i]) * cd[i];
;   }
; }

@cb = common global [4096 x i32] zeroinitializer, align 8
@cc = common global [4096 x i32] zeroinitializer, align 8
@cd = common global [4096 x i32] zeroinitializer, align 8
@ca = common global [4096 x i32] zeroinitializer, align 8
