------- Comment #3 from pinskia at gcc dot gnu dot org 2008-03-28 23:11 -------
We actually accept this code now but reject the following code now:
#define __vector __attribute__((vector_size(16)))
template <class A>
void f(A, __vector A, int);
void g(void)
{
__vector int a;
f<int>(1, a, 2);
}
Even though we have the attribute here and don't reject it any more, it gets
lost when instantiating the template.
The testcase in comment #1 works fully correct and we don't lose the attribute
as shown by:
#define __vector __attribute__((vector_size(256)))
template <class A>
struct b
{
__vector A t;
};
typedef int g[sizeof(b<int>) == sizeof(__vector int) ? 1 : -1 ];
CCing Jason since he implemented late attribute handling for 4.3.0.
