* toplev.h (flag_delete_null_pointer_checks): Move from here to...
* flags.h (flag_delete_null_pointer_checks): Here.
* tree-flow.h (cprop_into_successor_phis): Add argument to prototype.
* tree-phinodes.c (resize_phi_node): Initialize PHI_ARG_NONZERO.
(add_phi_arg, remove_phi_arg_num): Similarly.
* tree-ssa-copy.c (cprop_into_successor_phis): Propagate nonzero
property into PHI nodes.
* tree-ssa-dom.c: Remove redundant inclusion of flags.h.
(record_equivalences_from_phis): If all PHI arguments are known to be
nonzero, then the result must be nonzero as well.
(cprop_into_phis): Pass nonzero_vars bitmap to cprop_into_successor_phis (record_equivalences_from_stmt): Check flag_delete_null_pointer_checks
appropriately. Walk the USE-DEF chains and propagate nonzero property
as appropriate.
* tree.h (PHI_ARG_NONZERO): Define.
(phi_arg_d): Add nonzero flag.
