Extensive changes to move the bulk of the linker into BFD so that
more efficient backend code can be written for specific object
files. Only existing efficient backend is a.out.
* seclet.c, seclet.h: Removed.
* hash.c, linker.c, genlink.h: New files.
* bfd-in.h: Removed bfd_error_vector. Declared hash table
structures and functions.
(JUMP_TABLE): Removed bfd_seclet_link, added
bfd_link_hash_table_create, bfd_link_add_symbols and
bfd_final_link.
* All backends: Changed accordingly.
* bfd-in2.h: Rebuilt.
* bfd.c (struct _bfd): Added link_next and archive_pass fields.
Removed ld_symbols field.
(bfd_nonrepresentable_section, bfd_undefined_symbol,
bfd_reloc_value_truncated, bfd_reloc_is_dangerous,
bfd_error_vector): Removed.
(bfd_default_error_trap, bfd_error_trap,
bfd_error_nonrepresentabltrap): Removed.
(bfd_get_relocated_section_contents): Pass link_info. Pass
link_order instead of seclet. Pass symbols.
(bfd_relax_section): Pass link_info.
(bfd_seclet_link): Removed.
(bfd_link_hash_table_create, bfd_link_add_symbols,
bfd_final_link): New macros.
* libbfd-in.h: If __GNUC__ is defined and alloca is not, define
alloca as __builtin_alloca. Declare internal linking functions.
* libbfd.h: Rebuilt.
* libbfd.c (bfd_seek): Comment out fseek assertion. It's worked
for months.
* reloc.c (reloc_howto_type): Added error_message argument to
special_function field. Changed all callers and all definitions.
(bfd_get_reloc_size): Make argument a const pointer.
(bfd_perform_relocation): Add error_message argument to hold
string set if return value if bfd_reloc_dangerous. Changed all
callers.
(_bfd_final_link_relocate, _bfd_relocate_contents): New functions.
* section.c (asection): Renamed seclets_head and seclets_tail to
link_order_head and link_order_tail.
* targets.c (bfd_target): Replaced seclet argument with link_info
and link_order and symbols arguments in
bfd_get_relocated_section_contents. Added symbols argument to
bfd_relax_section. Removed bfd_seclet_link. Added
bfd_link_hash_table_create, bfd_link_add_symbols and
bfd_final_link.
* libaout.h (struct aoutdata): Added external_syms,
external_sym_count, external_strings, sym_hashes fields.
(obj_aout_external_syms, obj_aout_external_sym_count,
obj_aout_external_strings, obj_aout_sym_hashes): New accessor
macros.
(WRITE_HEADERS): Only output symbols if outsymbols is not NULL.
* aoutx.h: Wrote new back end linker routines.
(translate_to_native_sym_flags): Return boolean value. Don't use
bfd_error_vector.
(NAME(aout,write_syms)): Return boolean value. Check return value
of translate_to_native_sym_flags and bfd_write.
* aout-target.h (final_link_callback): New function.
(MY_bfd_final_link): New function.
* aout-adobe.c (aout_adobe_write_object_contents): Check return
value of aout_32_write_syms.
* hp300hpux.c (MY(write_object_contents)): Likewise.
* i386lynx.c (WRITE_HEADERS): Likewise.
* libaout.h (WRITE_HEADERS): Likewise.
* bout.c: Changed functions to use link_info->callbacks rather
than bfd_error_vector, and link_orders rather than seclets.
* coff-alpha.c: Likewise.
* coff-h8300.c: Likewise.
* coff-h8500.c: Likewise.
* coff-sh.c: Likewise.
* coff-z8k.c: Likewise.
* elf32-hppa.c: Likewise.
* reloc16.c: Likewise.
* coff-alpha.c (alpha_ecoff_get_relocated_section_contents): Look
up _gp in the hash table rather than in outsymbols.
* coff-a29k.c (a29k_reloc): Pass errors back in new error_message
argument rather than printing them.
* coffcode.h (bfd_coff_reloc16_extra_cases): Take link_info and
link_order arguments rather than seclet. Changed all uses and
definitions.
(bfd_coff_reloc16_estimate): Pass link_info arguments. Changed
all uses and definitions.
* libcoff.h: Rebuilt.
* ecoff.c (ecoff_get_extr): If symbol is defined by linker, but
not by ECOFF, make it scAbs.
(ecoff_bfd_final_link): Renamed from ecoff_bfd_seclet_link and
rewritten.
* elf32-mips.c (mips_elf_final_link): Renamed from
mips_elf_seclet_link and rewritten.
* elf32-hppa.c (elf32_hppa_stub_description): Added link_info
field.
(new_stub, add_stub_by_name, hppa_elf_build_arg_reloc_stub,
hppa_elf_build_long_branch_stub, hppa_look_for_stubs_in_section):
Added link_info arguments. Changed all callers.
* elfcode.h (elf_slurp_symbol_table): Don't quit if outsymbols is
not NULL.
* oasys.c (oasys_write_sections): Return boolean value rather than
using bfd_error_vector.
(oasys_write_object_contents): Check return value of
oasys_write_sections.
* hosts/std-host.h: Don't declare qsort or strtol.
