[Bug middle-end/33617] New: ICE for nonconstant callee-copied constructor arguments

["rsandifo at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following code:

---------------------------------------------------------------------------
typedef float V8SF __attribute__ ((vector_size (32)));
void test0 (V8SF);
void
foo (float x)
{
  test ((V8SF) { x, x, x, x, x, x, x, x });
}
---------------------------------------------------------------------------

causes an ICE on targets for which the vector argument is callee-copied:

---------------------------------------------------------------------------
/tmp/foo.c: In function 'foo':
/tmp/foo.c:6: internal compiler error: in copy_constant, at varasm.c:3067
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
---------------------------------------------------------------------------

We try to take the address of the original CONSTRUCTOR (rather than
a temporary as in the caller-copied case) and expand_expr_addr_expr_1
assumes that all constructors are constant.
