* cp-tree.h (BV_USE_VCALL_INDEX_P): New macro. (BV_GENERATE_THUNK_WITH_VTABLE_P): Likewise. (lang_decl_flags): Add generate_with_vtable_p. Make vcall_offset a tree, not an int. (THUNK_GENERATE_WITH_VTABLE_P): New macro. (make_thunk): Change prototype. (emit_thunk): Rename to use_thunk. (mangle_thunk): Change prototype. * class.c (get_derived_offset): Simplify. (copy_virtuals): Clear BV_USE_VCALL_INDEX_P and BV_GENERATE_THUNK_WITH_VTABLE_P. (build_primary_vtable): Simplify. (add_virtual_function): Use BV_FN, rather than TREE_VALUE. (dfs_find_base): Remove. (update_vtable_entry_for_fn): Correct bug in finding the base where a virtual function was first declared. Figure out whether or not to emit a vcall-thunk with the vtables in which it appears. Correct logic for deciding whether to use an ordinary thunk, or a vcall thunk. (finish_struct_1): Remove unnecssary code. (build_vtbl_initializer): Use ssize_int for the running counter of negative indices. (build_vtbl_initializer): Only use vcall thunks where necessary. Mark thunks as needing to be emitted with their vtables, or not. (build_vbase_offset_vtbl_entries): Adjust for use of ssize_int in indices. Use size_binop. (dfs_build_vcall_offset_vtbl_entries): Don't rely on BINFO_PRIMARY_MARKED_P here. Use BV_FN consistently. Use size_binop. (build_rtti_vtbl_entries): Adjust call to build_vtable_entry. (build_vtable_entry): Mark thunks as needing to be emitted with their vtables, or not. * decl.c (lang_mark_tree): Mark the vcall_offset in a thunk. * decl2.c (mark_vtable_entries): Use use_thunk instead of emit_thunk. * dump.c (dequeue_and_dump): Remove dead code. Dump new thunk information. * error.c (dump_expr): Use BV_FN. * mangle.c (mangle_thunk): Adjust now that vcall_offset is a tree, not an int. * method.c (make_thunk): Likewise. (emit_thunk): Rename to use_thunk. Allow callers to decide whether or not to actually emit the thunk. Adjust for changes in representation of vcall offsets. * search.c (dfs_get_pure_virtuals): Use BV_FN. * semantics.c (emit_associated_thunks): New function. (expand_body): Use it. * ir.texi: Adjust decriptions of thunks. From-SVN: r34656 |
