I looked at the back-end changes too but I will note that we have a
generic vector issue with mangling anyways and really should be fixing
that issue generically.  Try this generic code with any version of GCC
post 3.3:

typedef __attribute__((vector_size(8) )) int v8i;
typedef __attribute__((vector_size(16) )) int v16i;

template <typename t> void f(t ) {}

void g(void)
{
  v8i a;
  v16i b;
  f(a);
  f(b);
}


And the implementation above only works for the builtin types that the
ARM back-end provides and not the attribute vector_size based ones.

So even you cannot intermix the generic vectors with the builtin types
which seems wrong.

Thanks,
