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_asymbol_chain, get_asymbol_chain, get_loader_symbol, 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_fold_tree): Likewise. Also, handle etree_rel case. (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_relocate_globals): Removed. (lang_finish): Use link hash table rather than ldsym functions. (lang_common): Rewrote. (lang_one_common): New function. (ldlang_add_file): Add file to link_info.input_bfds list. Set usrdata. (create_symbol): Removed. (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. (read_entry_symbols, refize, enter_global_ref, enter_file_symbols, search_library, gnu960_check_format, decode_library_subfile, linear_library, symdef_library, clear_syms, subfile_wanted_p): Removed. (add_keepsyms_file, add_archive_element, multiple_definition, multiple_common, add_to_set, warning_callback, undefined_symbol, reloc_overflow, reloc_dangerous, unattached_reloc, notice_ysym): New functions. * ldmisc.c (vfinfo): Accept a string for %T, not a symbol. Don't require symbols for %C; look them up instead. * emultempl/hppaosf.em: Pass link_info to 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. * Makefile.in (ldlex.c): Don't depend on ldgram.h. Remove declarations of free and malloc from flex output. Change malloc to ldmalloc in flex output.

* ldfile.c (ldfile_open_command): Don't try .ld extension. It wasn't documented (or likely used) and wastes time. (try_open): If EXTEN is empty, don't try it. * ldctor.c, lderror.c, ldexp.c, ldfile.c, ldindr.c, ldlang.c, ldlex.l, ldmain.c, ldmisc.c, ldsym.c, ldver.c, ldwarn.c, ldwrite.c, lexsup.c, mri.c, relax.c: Replace DEFUN macro calls with normal function declarations. * Move *.em to emultempl/*.em. Move *.sh to emulparams/*.sh. Move *.sc-sh to scripttempl/*.sc. * {emultempl,emulparams,scripttempl}/README: New files. * sh.em, st2000.em, z8ksim.em, h8300hms.em, h8500hms.em: Files removed, replaced with generic.em. * h8300.sh, h8500.sh, h8300.sc, h8500.sc: Renamed from h8[35]00hms.s[ch]. Change their contents to omit the "hms". * *.em (*_get_script): Return script name instead of script contents. * ldlang.c (lang_process): Change caller. * ldlex.l, ldgram.y: Recognize -m option. Check for input files after *all* options in grammar. * ldmain.c (main): Check for -m options. Add default directory for -m. * mkscript.c: File removed. * genscripts.sh: Take two more parameters, tooldirlib and libdir, to add to the default LIB_PATH. Look for input files in the new subdirectories. Create the scripts in emulations subdirectory and don't filter them through mkscript. * configure.in: Make the emulations subdirectory. * Makefile.in: Account for all of the above changes. Remove unused .SUFFIXES. Get libgcc.a path with gcc -print-libgcc-file-name instead of $(libdir)/libgcc.a. Put CFLAGS last in the compilation rules. Add -I../bfd to INCLUDES so sysdep.h is found. * ldfile.c (try_open): If opening without the extension fails, try with the extension even if -v or -V was given. had_script is imported (from ldgram.y), not exported.
