tree.h (fold_indirect_ref_1): Export from fold-const.c.
2005-06-01 Richard Guenther <rguenth@gcc.gnu.org>
* tree.h (fold_indirect_ref_1): Export from fold-const.c.
* fold-const.c (fold_indirect_ref_1): No longer static.
* tree-inline.c (copy_body_r): Use fold_indirect_ref_1 for
folding, if possible.
