Author: jakub Date: Wed Nov 18 09:53:52 2009 New Revision: 154284 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=154284 Log: PR c++/3187 * cgraph.h (struct cgraph_node): Add same_body and same_body_alias fields. (cgraph_same_body_alias, cgraph_remove_same_body_alias): New prototypes. * cgraphunit.c (cgraph_expand_function, cgraph_emit_thunks, cgraph_materialize_all_clones): Handle same_body aliases. * cgraph.c (cgraph_allocate_node): New function. (cgraph_create_node): Use it. (cgraph_node_for_decl, cgraph_node, cgraph_get_node, cgraph_node_for_asm, cgraph_remove_node): Handle same_body aliases. (cgraph_same_body_alias, cgraph_remove_same_body_alias): New functions. * lto-cgraph.c (lto_output_node): Stream out same_body aliases. (input_node): Stream in same_body aliases. * lto-symtab.c (lto_cgraph_replace_node): Clear node pointers for same_body aliases. (lto_symtab_merge_cgraph_nodes_1): Handle same_body aliases. * cp-tree.h (expand_or_defer_fn_1): New prototype. * decl2.c (cp_write_global_declarations): Mark as !DECL_EXTERNAL also all same_body aliases. * semantics.c (expand_or_defer_fn): Move most of the function except registering with cgraph to ... (expand_or_defer_fn_1): ... here. New function. * optimize.c: Include cgraph.h. (maybe_clone_body): If in charge parm is not used and both base and complete clones are created and are not comdat, tell cgraph they have the same body. * Make-lang.in (cp/optimize.o): Depend on $(CGRAPH_H). * g++.dg/abi/mangle26.C: Also match *C2* definition. * g++.dg/abi/mangle27.C: Likewise. * g++.dg/abi/mangle28.C: Likewise. * g++.dg/abi/mangle29.C: Likewise.
