[Bug tree-optimization/28952] [4.2 regression] tree check: expected class 'expression', have 'exceptional' (ssa_name) in vectorizable_condition, at tree-vect-transform.c:2122

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-09-04 19:15 -------
Confirmed, we have:
  D.1539_10 = pplayer_4->spaceship.structure[j_11];
  iftmp.1_2 = D.1539_10 ? 49 : 48;

Which is valid.
It is caued by:
  /* We do not handle two different vector types for the condition
     and the values.  */
  if (TREE_TYPE (TREE_OPERAND (cond_expr, 0)) != TREE_TYPE (vectype))
    return false;

Which was added by:

        PR tree-optimization/27151
        * tree-vect-transform.c (vectorizable_condition): Punt on
        values that have a different type than the condition.

I also bet this is a latent (or even ICE only when checking) bug on the 4.1
branch too.
