Compiling the following with -m64 -O1 -maltivec -mabi=no-altivec
results in misaligned lvx data accesses in bar.
-m32 -O1 -maltivec -mabi=no-altivec results in misaligned stvx data accesses in f.
#define vector __attribute__ ((vector_size (16)))
vector int v1;
extern void bar (int, vector int, vector int, vector int,
vector int, vector int);
void f (void)
{
bar (2, v1, v1, v1, v1, v1);
}
void bar (int a, vector int b, vector int c, vector int d,
vector int e, vector int f)
{
v1 = b + c + d + e + f;
}
