/* A YACC grammer to parse a superset of the AT&T linker scripting languaue.
|
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_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.

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.

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.
