--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Mon Jan 15 08:57:28 2018 New Revision: 256685 URL: https://gcc.gnu.org/viewcvs?rev=256685&root=gcc&view=rev Log: 2018-01-15 Richard Biener <rguent...@suse.de> PR lto/83804 * tree.c (free_lang_data_in_type): Always unlink TYPE_DECLs from TYPE_FIELDS. Free TYPE_BINFO if not used by devirtualization. Reset type names to their identifier if their TYPE_DECL doesn't have linkage (and thus is used for ODR and devirt). (save_debug_info_for_decl): Remove. (save_debug_info_for_type): Likewise. (add_tree_to_fld_list): Adjust. * tree-pretty-print.c (dump_generic_node): Make dumping of type names more robust.
