4fdbafb247 Changes to make -Ur work again.
* ldmain.c (add_to_set): Now takes reloc argument rather than
	bitsize.  Check config.build_constructors here.  If an new hash
	table entry is created, mark it as undefined.
	(constructor_callback): No longer takes bitsize argument.  Pass
	BFD_RELOC_CTOR to ldctor_add_set_entry, but first make sure the
	BFD backend supports it.
	(reloc_overflow): Handle a NULL abfd argument.
	(reloc_dangerous, unattached_reloc): Likewise.
	* ldctor.c: Include ldmain.h.
	(struct set_info): Change bitsize field to reloc.
	(ldctor_add_set_entry): Now takes reloc argument rather than
	bitsize.  Don't bother to check config.build_constructors here.
	(ldctor_build_sets): Get the size from the reloc howto.  If
	generating relocateable output, call lang_add_reloc rather than
	lang_add_data.
	* ldctor.h (ldctor_add_set_entry): Change declaration to use reloc
	instead of bitsize.
	* ldlang.h (statement_enum): Add lang_reloc_statement_enum.
	(lang_reloc_statement_type): New structure.
	(lang_statement_union_type): Add reloc_statement field.
	(lang_add_reloc): Declare new function.
	* ldlang.c (lang_for_each_statement_worker): Handle
	lang_reloc_statement_enum.
	(map_input_to_output_sections, print_statement): Likewise.
	(lang_size_sections, lang_do_assignments): Likewise.
	(print_reloc_statement): New function.
	(lang_add_reloc): New function.
	* ldwrite.c (build_link_order): Handle lang_reloc_statement_enum.

4a6afc88bb A major rewrite to move the bulk of the linker into BFD so that
more efficient backend code can be written for specific object
	files.
	* lderror.c, lderror.h, ldindr.c, ldindr.h, ldsym.c, ldsym.h,
	ldwarn.c, ldwarn.h, relax.c, relax.h: Removed.
	* ldctor.c, ldctor.h: Complete rewrite.
	* ldwrite.c, ldwrite.h: Complete rewrite.
	* ld.h (strip_symbols_type, strip_symbols): Removed.  Use
	link_info.strip instead.  Changed all uses.
	(discard_locals_type, discard_locals): Removed.  Use
	link_info.discard instead.  Changed all uses.
	(ld_config_type): Removed relocateable_output field; use
	link_info.relocateable instead; changed all uses.  Added stats
	field.

	set_loader_symbol): Removed.
	* ldexp.h (node_class): Added etree_rel.
	(etree_type): Added rel field.
	* ldexp.c (exp_print_token): Bracketed table initialization.
	(exp_relop): New function.
	(fold_name): Use linker hash table rather than ldsym functions.

	(exp_print_tree): Handle etree_rel.
	* ldgram.y (strip_symbols, discard_locals): Removed.
	(OPTION_stats, OPTION_no_keep_memory): New tokens.  Handle them.
	(REL): New token.  Does not appear in grammar, but needed for
	expression code.
	(file): Don't call lang_final; it's called by main anyhow.
	* ldlex.l: Accept -stats and -no-keep-memory options.
	* ldlang.h (fill_type): Make unsigned int, not unsigned short.
	* ldlang.c: Consistently use fill_type for fill argument.
	(lang_init_script_file, script_file): Removed.
	(create_object_symbols): Removed.  Use
	link_info.create_object_symbols_section instead.  Changed all
	uses.
	(lang_add_keepsyms_file): Removed.
	(lookup_name): Call bfd_link_add_symbols instead of
	ldmain_open_file_read_symbol.
	(wild): Don't iterate over script_file.
	(open_output): Create link hash table.
	(lang_place_undefineds): Rewrote.
	(lang_size_sections): Handle relaxing (doesn't work yet).

	(lang_process): Don't call lang_init_script_file.  Call
	ldctor_build_sets rather than find_constructors.  Don't call
	lang_relocate_globals.
	(lang_abs_symbol_at_beginning_of): Rewrote.
	(lang_abs_symbol_at_end_of): Rewrote.
	* ldmain.c (had_y): Removed.
	(lprefix, lprefix_len): Removed; use link_info fields instead.
	Changed all uses.
	(multiple_def_count, commons_pending, undefined_global_sym_count,
	total_symbols_seen, total_files_seen): Removed.
	(link_callbacks, link_info): New variables.
	(main): Initialize link_info.  Don't call init_bfd_error_vector or
	ldsym_init.  Don't set now unused variables.  Handle -stats.
	(get_emulation): Removed obsolete and nonfunctional GNU960 code.
	(add_ysym): Rewrote.

	hppa_look_for_stubs_in_section.
	* Makefile.in: Rebuilt dependencies.
	(CFILES): Removed lderror.c, ldindr.c, ldsym.c, ldwarn.c, and
	relax.c.
	(HFILES): Removed lderror.h, ldindr.h, ldsym.h, ldwarn.h, and
	relax.h.
	(EMULATION_OFILES): Depend on bfdlink.h, ldmain.h, ldexp.h,
	ldlang.h and ldctor.h.
