[Bug tree-optimization/35468] LHS of assignment can be folded to a constant causing ICE

[rguenth at gcc dot gnu dot org]

------- Comment #1 from rguenth at gcc dot gnu dot org  2008-03-05 15:27 -------
This is done by several passes through the magics of fold_stmt_r:

    case ARRAY_REF:
      /* If we are not processing expressions found within an
         ADDR_EXPR, then we can fold constant array references.  */
      if (!*inside_addr_expr_p)
        t = fold_read_from_constant_string (expr);
      else
        t = NULL;
      break;

we should remember if we are visiting the LHS of an expression here.
