tree-ssa-propagate.h (struct prop_value_d, [...]): Move ...
2010-08-04 Richard Guenther <rguenther@suse.de>
* tree-ssa-propagate.h (struct prop_value_d, prop_value_t): Move ...
* tree-ssa-ccp.c: ... here.
* tree-ssa-copy.c: ... and here.
* tree-ssa-propagate.h (enum value_range_type, struct value_range_d,
value_range_t): Move ...
* tree-vrp.c: ... here.
* tree-ssa-propagate.h (ssa_prop_get_value_fn): New typedef.
(substitute_and_fold): Adjust prototype.
* tree-ssa-propagate.c (replace_uses_in): Adjust.
(replace_phi_args_in): Likewise.
(substitute_and_fold): Take callback to query lattice instead
of pointer to lattice. Replace SSA name defs with lattice
values first.
* tree-ssa-ccp.c (ccp_finalize): Adjust.
* tree-ssa-copy.c (copy_prop_visit_phi_node): Adjust.
(get_value): New function.
(fini_copy_prop): Adjust.
* tree-vrp.c (vrp_finalize): Adjust.
* gcc.dg/tree-ssa/vrp35.c: Adjust.
* gcc.dg/tree-ssa/vrp36.c: Likewise.
* gcc.dg/tree-ssa/vrp50.c: Likewise.
* gcc.dg/tree-ssa/vrp52.c: Likewise.
