tree-ssa-propagate.h (ssa_prop_visit_stmt_fn): Remove typedef.
* tree-ssa-propagate.h (ssa_prop_visit_stmt_fn): Remove typedef. (ssa_prop_visit_phi_fn): Likewise. (class ssa_propagation_engine): New class to provide an interface into ssa_propagate. * tree-ssa-propagate.c (ssa_prop_visit_stmt): Remove file scoped variable. (ssa_prop_visit_phi): Likewise. (ssa_propagation_engine::simulate_stmt): Moved into class. Call visit_phi/visit_stmt from the class rather than via file scoped static variables. (ssa_propagation_engine::simulate_block): Moved into class. (ssa_propagation_engine::process_ssa_edge_worklist): Similarly. (ssa_propagation_engine::ssa_propagate): Similarly. No longer set file scoped statics for the visit_stmt/visit_phi callbacks. * tree-complex.c (complex_propagate): New class derived from ssa_propagation_engine. (complex_propagate::visit_stmt): Renamed from complex_visit_stmt. (complex_propagate::visit_phi): Renamed from complex_visit_phi. (tree_lower_complex): Call ssa_propagate via the complex_propagate class. * tree-ssa-ccp.c: (ccp_propagate): New class derived from ssa_propagation_engine. (ccp_propagate::visit_phi): Renamed from ccp_visit_phi_node. (ccp_propagate::visit_stmt): Renamed from ccp_visit_stmt. (do_ssa_ccp): Call ssa_propagate from the ccp_propagate class. * tree-ssa-copy.c (copy_prop): New class derived from ssa_propagation_engine. (copy_prop::visit_stmt): Renamed from copy_prop_visit_stmt. (copy_prop::visit_phi): Renamed from copy_prop_visit_phi_node. (execute_copy_prop): Call ssa_propagate from the copy_prop class. * tree-vrp.c (vrp_prop): New class derived from ssa_propagation_engine. (vrp_prop::visit_stmt): Renamed from vrp_visit_stmt. (vrp_prop::visit_phi): Renamed from vrp_visit_phi_node. (execute_vrp): Call ssa_propagate from the vrp_prop class. From-SVN: r254329
