1582 (elf_link_create_dynamic_sections): If dynamic sections were
1583 already created, don't do anything. If dynobj is already set, use
1584 it; otherwise, set it to the bfd argument. Don't initialize

1601 (elf_i386_check_relocs): Just call elf_i386_create_got_section if
1602 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.

1606 (elf_i386_adjust_dynamic_symbol): Rework initial assertion to
1607 permit ELF_LINK_HASH_NEEDS_PLT non dynamic symbols. Create a

1640 seen, skip most of this function, and force the size of the
1641 .rela.got section to zero. Strip empty reloc sections, and strip
1642 an empty .plt section.
1643 (elf32_sparc_relocate_section): For a GOT reloc against a global
1644 symbol when no dynamic object was seen, initialize the contents of
1645 the .got section. For a GOT reloc against a local symbol, only
1646 create a R_SPARC_RELATIVE reloc when generating a shared object.
1647 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1648 create a PLT entry as a R_SPARC_WDISP30 reloc.
1649 (elf32_sparc_finish_dynamic_sections): Only fiddle with the

1665 storage class slightly more verbose. It's not clear how many
1666 characters I can justify using up, but before this change they
1667 both were abbreviated "sc" which is (IMHO) clearly unacceptable.

5220 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5222 Support for link_order types which generate relocs in order to
5223 support -Ur in the linker.
5224 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5225 from call to _bfd_generic_link_add_one_symbol.
5226 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5227 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5228 instead of bitsize to add_to_set call back.
5229 (_bfd_generic_final_link): Account for link_order relocs when
5230 allocating space for relocations. Handle them in link_order loop.
5231 (_bfd_generic_reloc_link_order): New function.
5232 (_bfd_default_link_order): If a reloc_link_order is seen here,
5234 (_bfd_count_link_order_relocs): New function.
5235 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5236 argument from declaration.
5237 (_bfd_generic_reloc_link_order): Declare.
5238 (_bfd_count_link_order_relocs): Declare.
5239 * libbfd.h: Rebuilt.
5240 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5241 call to _bfd_generic_link_add_one_symbol.
5242 (NAME(aout,final_link)): Account for link_order relocs when
5243 allocating space for relocations. Handle them after handling all
5245 (aout_link_reloc_link_order): New function.
5246 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
5247 call to _bfd_generic_link_add_one_symbol.
5248 (ecoff_bfd_final_link): Account for link_order relocs when
5249 allocating space for relocations. Handle them in link_order loop.
5250 (ecoff_link_write_external): Set the storage class of a defined
5251 linker created symbol based on the section it is in. Correct
5252 bfd_link_hash_weak case to use .sc rather than .st.
5253 (ecoff_reloc_link_order): New function.
5254 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5256 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5258 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5261 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5262 bfd_zmalloc. Free a pointer, not a union.
5263 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5265 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5267 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5269 * som.c (bfd_section_from_som_symbol): Only to do the value
5270 comparison for function symbols within executables.
5272 * som.c (bfd_section_from_som_symbol): Renamed from
5273 som_section_from_subspace_index. Pass in a native SOM symbol.
5274 For executables, iterate through the sections to find out
5275 which contains the symbol's address rather than using the
5276 symbol_info field. (symbol_info has a different meaning for
5277 dynamicly linked executables.)
5279 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5282 * som.c (som_begin_writing): Fix braino (one call to align
5283 space/subspace data was done unconditionally rather than
5284 just for executables.)
5286 * som.c (som_begin_writing): Align text in all executables to
5287 make HPUX kernel happy. Fixes strip/objcopy for shared
5290 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5292 * som.c (som_begin_writing): Account for alignment needs of
5293 subspaces too when writing executables. Never request a negative
5294 bss size. Fixes some problems with demand paged executables,
5295 still having problems with pure executables and shared executables.
5297 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5299 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5300 bfd_zalloc for rawptr, because later on we may call free, not
5303 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5304 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5305 * cisco-core.c: New file.
5306 * Makefile.in: Change accordingly.
5307 * configure.in: Recognize cisco_core_vec.
5308 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5309 * targets.c: Add cisco_core_vec.
5310 * bfd-in2.h: Rebuilt.
5312 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5314 * som.h (som_copyable_section_data_struct): New structure
5315 containing all the private section information which needs
5316 to be copied from input section to output section during
5318 (som_section_data_struct): Remove several fields now in
5319 som_copyable_section_data_struct. Make the space and
5320 subspace dictionaries be pointers (to save space when
5321 only reading objects).
5323 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5324 some references changed. Allocate a copyable data stucture if
5325 none exists. Store info into the copyable data structure.
5326 (bfd_som_set_subsection_attributes): Likewise.
5327 (som_is_space, som_is_subspace, som_is_container): New functions.
5328 Use these instead of directly accessing private data.
5329 (som_prep_headers): Allocate space and subspace headers here.
5330 Fill in some fields in the space/subspace headers from the
5332 (som_bfd_copy_private_section_data): Only copy the stuff
5333 that we really need to make objcopy and strip work. Allocate
5334 the copy_data structure for the output bfd before copying.
5336 * som.h (struct som_exec_data): New structure to hold exec
5337 info that must be preserved when running objcopy/strip.
5338 (struct somdata): Add new "exec_data" field and accessor
5339 macro. Add some comments on how the various fields are used.
5340 (som_section_data_struct): Make is_space and is_subspace bitfields.
5341 Delete unused subspace_index. All references now use the
5342 target_index field within the section structure itself.
5344 * som.c (make_unique_section): Delete unused declaration.
5345 (som_bfd_copy_private_bfd_data): New function.
5346 (som_object_setup): Allocate space for and save exec information
5347 that needs to be copied during objcopy/strip.
5348 (som_mkobject): Do not allocate space for a file header here.
5349 It is not used when only reading SOM objects.
5350 (som_prep_headers): Allocate space for and attach a file header
5351 to the output bfd. For executables, use the saved system_id
5352 value rather than trying to guess the right value. Do not abort
5353 wwhen setting file_hdr->entry* for executables.
5354 (som_begin_writing): For executables, set the exec_entry and
5356 (som_copy_private_backend_section_data): Always return a value.
5358 * libhppa.h (PA_PAGESIZE): Define.
5360 * som.c (SOM_ALIGN): Define.
5361 (som_begin_writing): If writing an executable, initialize all
5362 fields in the exec header to zero. Update fields in the exec
5363 header as sizes of loadable subspaces are computed. Carefully
5364 preserve alignments when building executables. Actually write the
5365 exec after all the fields are filled in.
5367 * Better long-filename handling. Reads SOM ABI compliant extended
5368 names, but doesn't quite write compliant extended names yet.
5369 * som.c (som_slurp_extended_name_table): Delete function. The
5370 generic code will handle things correctly.
5371 (som_slurp_armap): Seek to the beginning of the next member.
5372 (normalize): New function.
5373 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5374 name table into account when computing the file offsets in the
5375 SOM dictionary. Make sure to align to an even boundary.
5376 (som_write_armap): Initialize the checksum to zero.
5377 (ar_maxchars): Fix. Opps.
5379 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5381 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5382 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5384 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5386 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5387 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5388 * bfd-in2.h: Regenerated.
5390 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5391 this was also named trad_unix_bfd_copy_private_bfd_data.
5393 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5395 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5396 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5397 returns NULL, it is not an error. It's possible that some of
5398 these checks are not necessary (because the size can never be
5399 zero), but putting in the checks is the conservative thing to do
5400 in light of the fact that some of these malloc calls replaced
5401 unchecked alloca calls, in which a zero argument would work fine.
5403 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5405 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5406 duplicate definition.
5407 (osf_core_bfd_is_local_label): Define.
5409 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5410 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5411 failure indication, it merely means there are no relocs.
5413 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5414 after NAME, since SunOS /bin/cc can't handle it.
5416 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5418 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5419 From sukes@glue.umd.edu (Tasuki Hirata).
5421 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5423 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5424 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5425 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5427 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5429 * som.c (som_prep_for_fixups): Detect section symbols based
5430 on either the lack of private data or the symbol flags. Do not
5431 munge section symbol names anymore -- they no longer confuse GDB.
5432 (som_begin_writing): Leave space for an exec header if writing
5434 (som_slurp_symbol_table): Recognize both forms of section symbol
5435 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5436 section symbols to be the name of the section they represent.
5437 Debugging symbols begin with "L$0\001", not just "L$".
5439 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5441 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5443 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5444 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5445 and bfd_is_local_label.
5447 * targets.c: Add new entries to the bfd_target structure.
5449 * bfd.c (bfd_copy_private_bfd_data): New definition.
5451 * section.c (bfd_copy_private_section_data): New definition.
5453 * syms.c (bfd_is_local_label): New definition.
5455 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5457 * libbfd.c (bfd_generic_is_local_label): New function.
5459 * *-core.c: Provide default definitions for new functions in
5460 the target vector which all point to bfd_false.
5462 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5463 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5464 Default new vectors for copying private backend data to bfd_true.
5465 Default new vector for determining if a symbol is a local label
5466 to bfd_generic_is_local_label.
5468 * som.c (som_bfd_copy_private_section_data): New function.
5469 (som_bfd_is_local_label): New function.
5470 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5472 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5474 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5476 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5478 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5481 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5482 Indent some of them to GNU standards.
5484 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5485 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5486 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5487 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5488 Update copyright years.
5490 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5492 * som.c (som_prep_for_fixups): A relocation involving the section
5493 symbol for the *ABS* section is really a relocation involving
5495 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5496 undefined symbols. Correctly distinguish between debugger symbols
5497 and section symbols.
5499 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5500 for spaces and subspaces.
5502 * som.c (som_bfd_count_ar_symbols): Fix typo.
5504 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5505 HAS_RELOC based on the object's magic number.
5506 (make_unique_section): Delete function. BFD and its users are
5507 prepared to handle multiple sections with the same name.
5508 (setup_sections): Allocate space on the BFD's obstack to hold
5509 section names. Use bfd_make_setion_anyway rather than the
5510 obsolete make_unique_section.
5511 (som_prep_headers): Choose the correct SOM magic number based
5513 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5515 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5517 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5518 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5519 * Makefile.in, configure.in: Corresponding changes.
5521 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5523 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5525 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5527 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5528 is always located at the start of the data section to allow
5529 recovery of the dynamic info from a stripped executable.
5530 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5533 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5535 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5536 cruft (like the #pragma alloca for AIX).
5537 In addition to that problem, the C alloca calls xmalloc, which
5538 means checking for being out of memory can't work right. The
5539 following changes remove all uses of alloca from BFD.
5540 * hosts/solaris2.h: Remove alloca cruft.
5541 * som.c: Replace alloca with a fixed size auto array.
5542 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
5543 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
5544 sunos.c: Replace alloca with malloc and appropriate error checking and
5546 * linker.c: Replace alloca with obstack_alloc.
5547 * libbfd.h: Rebuilt.
5549 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5551 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5554 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5556 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5557 Elf*_Off typedefs by their expansion, the typedefs have been
5558 removed from include/elf/internal.h.
5559 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5560 SHT_PROGBITS section.
5562 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5564 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
5566 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5568 * configure.host: Recognize i[34]86-sequent-*.
5570 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5571 return from bfd_seek indicates an error.
5572 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5573 TRAD_CORE_STACK_OFFSET.
5574 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5575 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5577 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5579 * som.[ch]: Do not include libhppa.h in som.c, instead include
5582 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5583 include it in elf32-hppa.h.
5585 * som.c (log2): Return -1 on error rather than aborting.
5586 (setup_sections): Bubble up an error from log2.
5588 * Changes to make HP C compiler happy in both traditional
5590 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5592 (bfd_som_set_section_attributes): Use unsigned int rather than
5593 unsigned char to avoid GNU-C extensions.
5594 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5595 or failure rather than aborting on failure.
5597 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5599 (bfd_som_attach_aux_hdr): Add prototype.
5600 (hppa_som-gen_reloc_type): Likewise.
5602 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5603 (hppa_look_for_stubs_in_section): Do not return false on failure
5604 until rest of code is ready to handle it. Abort for now.
5606 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5608 * bfd-in2.h: Rebuilt.
5610 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
5612 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
5613 * Makefile.in: delete an extra blank.
5614 * configure.in : Add i396os9k_vec.
5616 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
5618 * config.bfd : Add i386-os9k.
5619 * config/i386-os9k.mt : Newly add os9k target makefile.
5621 * i386os9k.c : new file to handle os9k format bfd.
5622 * Makefile.in : Handle new file i386os9k.c
5623 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
5624 * cache.c : Initialize cache_sentinel to 0.
5626 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5628 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
5629 action in case where caller specified no argument relocation.
5630 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5631 right in the original relocation and the stub's relocation.
5633 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
5634 unused symbols argument.
5636 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
5637 than asymbol * for original target symbol. All callers changed.
5638 Set reloc->sym_ptr_ptr appropriately.
5639 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5640 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5641 argument. Use the output symbols when canonicalizing the relocs,
5642 creating them if necessary.
5644 * linker.c (_bfd_generic_link_output_symbols): Do not
5645 rebuild/clobber the output symbols if they already exist.
5647 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5649 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
5650 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
5651 * bfd-in2.h: Rebuilt.
5653 * srec.c (hex_value): Always set to a size of 256 bytes.
5654 (srec_init): Cosmetic changes.
5656 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5658 * elf32-hppa.c: Second half of major cleanup. More comments,
5659 PARAMize and staticize rest of functions. Delete unused
5660 functions. Delete unused/unnecessary arguments to some functions.
5661 Group static vars together. Abort for bad errors until we have
5662 error code propogation working. Work on spacing and indention.
5663 Add FIXMEs for unresolved problems. Use enums rather than
5664 #defines for lots of things. Merge two functions which build
5665 linker stubs into a single function (so they can easily share a
5666 ton of common code).
5668 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5670 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5671 avoid depending upon right shifts of signed numbers, and to

5890 bother processing them.

7872 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
7873 MY_bfd_seclet_link): Define.
7874 (MY_bfd_reloc_type_lookup): Rename from
7875 MY_reloc_howto_type_lookup.
7876 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
7877 (MY(vec)): Use JUMP_TABLE rather than listing functions.
7878 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
7879 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
7880 terms of MY, because that causes a recusive invocation of CAT when
7881 expanded within JUMP_TABLE, and ANSI compilers don't expand
7883 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7884 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7885 (MY_canonicalize_reloc): Don't define in terms of MY.
7886 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7887 than listing functions.
