------- Comment #1 from pinskia at gcc dot gnu dot org  2006-07-13 05:37 -------
Note a related testcase is:
#define vector __attribute__((vector_size(16)))
float f(vector float t)
{
  return *(float*)(&t);
}

Which is only mentioned here in get_alias_set in the GCC sources as being not
violating aliasing rules (see also
http://gcc.gnu.org/ml/gcc/2006-07/msg00250.html).
