tree-ssa-sccvn.c (vn_reference_op_eq): Use types_compatible_p instead of pointer equality.
2008-10-04 Richard Guenther <rguenther@suse.de>
* tree-ssa-sccvn.c (vn_reference_op_eq): Use types_compatible_p
instead of pointer equality.
(vn_nary_op_eq): Likewise.
* gcc.dg/tree-ssa/ssa-pre-21.c: New testcase.
