        PR middle-end/34856
        * tree-cfg.c (verify_expr): Allow all invariant expressions
        instead of just constant class ones as reference argument.
        * tree-ssa-loop-im.c (for_each_index): Handle CONSTRUCTOR
        like any other constant.
        * tree-ssa-sccvn.c (copy_reference_ops_from_ref): Likewise.

        * gcc.c-torture/compile/pr34856.c: New testcase.
