tree-cfg.c (verify_expr): Recurse again for invariant addresses.
2008-03-22 Richard Guenther <rguenther@suse.de>
* tree-cfg.c (verify_expr): Recurse again for invariant addresses.
For PHI nodes verify the address is invariant.
* tree-ssa-ccp.c (ccp_decl_initial_min_invariant): Remove.
(get_symbol_constant_value): Use is_gimple_min_invariant.
(maybe_fold_stmt_indirect): Likewise.
