#include "xmmintrin.h"
typedef struct {
__m128 x;
} SS_struct_mi128;
typedef union {
__m128 x;
} SS_union_mi128;
SS_union_mi128 un;
SS_struct_mi128 st;
test()
{
bar(un);
foo(st);
}
For the given program the Union and Struct have the same fields. gcc passes
the struct according to document but does not do the right thing for Union.
See output from gcc below
