[Bug tree-optimization/33614] New: ICE on semi-constant vector CONSTRUCTORs

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

The following code:

-----------------------------------------------------------------------
typedef float V2SF __attribute__ ((vector_size (8)));

V2SF
foo (int x, V2SF a)
{
  while (x--)
    a += (V2SF) {1.0f/0.0f - 1.0f/0.0f, 1.0f/0.0f - 1.0f/0.0f};
  return a;
}
-----------------------------------------------------------------------

produces an ICE when optimisation is enabled:

-----------------------------------------------------------------------
/tmp/foo.c: In function 'foo':
/tmp/foo.c:9: error: invalid reference prefix
{1.0e+0 / 0.0 + 1.0e+0 / -0.0, 1.0e+0 / 0.0 + 1.0e+0 / -0.0}

/tmp/foo.c:9: error: invalid reference prefix
{1.0e+0 / 0.0 + 1.0e+0 / -0.0, 1.0e+0 / 0.0 + 1.0e+0 / -0.0}
