1212
1213 Changes to support linker relaxing of embedded MIPS PIC code to

1220 the debugging information if it has already been read.
1221 (ecoff_indirect_link_order): Handle _cooked_size being different
1222 from _raw_size. Don't reread the contents or the relocs if they
1223 have already been read in.

1231 required by expansions. Set s and unset h when converting a reloc
1232 from undefined to section. Change handling of PC relative relocs:
1233 if against a section, they are correct in the object file, if
1234 against an external symbol they are pcrel_offset.

1326
1327 * elf32-mips.c (mips_elf_final_link): Account for link_order
1328 relocs when allocating space for relocations. Set SEC_RELOC flag
1329 for any section which has relocs. Handle link_order relocs in
1330 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1331 add_symbls entry point.
1332
1333 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before

1336
1337 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
1338
1339 * linker.c (_bfd_generic_link_add_symbols): Just call
1340 generic_link_add_symbols.
1341 (_bfd_generic_link_add_symbols_collect): New function, like
1342 _bfd_generic_link_add_symbols but also collect constructors and
1343 destructors by name as collect2 does.

1345 _bfd_generic_link_add_symbols but with collect argument.
1346 (generic_link_add_object_symbols): Take collect argument.

1355
1356 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1357
1358 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1359 for first character in an extended name.

1361 "//" as the name of the special archive member holding the
1362 extended name table.
1363
1364 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

1369 from call to _bfd_generic_link_add_one_symbol.
1370 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

1372 instead of bitsize to add_to_set call back.
1373 (_bfd_generic_final_link): Account for link_order relocs when
1374 allocating space for relocations. Handle them in link_order loop.
1375 (_bfd_generic_reloc_link_order): New function.
1376 (_bfd_default_link_order): If a reloc_link_order is seen here,
1377 abort.

1385 call to _bfd_generic_link_add_one_symbol.
1386 (NAME(aout,final_link)): Account for link_order relocs when
1387 allocating space for relocations. Handle them after handling all
1388 input BFDs.
1389 (aout_link_reloc_link_order): New function.
1390 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
1391 call to _bfd_generic_link_add_one_symbol.

1398 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1399 BFD_RELOC_CTOR.

1408
1409 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1410
1411 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1412
1413 * som.c (bfd_section_from_som_symbol): Only to do the value
1414 comparison for function symbols within executables.
1415
1416 * som.c (bfd_section_from_som_symbol): Renamed from
1417 som_section_from_subspace_index. Pass in a native SOM symbol.
1418 For executables, iterate through the sections to find out
1419 which contains the symbol's address rather than using the
1420 symbol_info field. (symbol_info has a different meaning for
1421 dynamicly linked executables.)
1422
1423 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1424 bfd_zmalloc.
1425
1426 * som.c (som_begin_writing): Fix braino (one call to align
1427 space/subspace data was done unconditionally rather than
1428 just for executables.)
1429
1430 * som.c (som_begin_writing): Align text in all executables to
1431 make HPUX kernel happy. Fixes strip/objcopy for shared
1432 executables.
1433
1434 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1435
1436 * som.c (som_begin_writing): Account for alignment needs of
1437 subspaces too when writing executables. Never request a negative
1438 bss size. Fixes some problems with demand paged executables,
1439 still having problems with pure executables and shared executables.
1440
1441 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1442
1443 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1444 bfd_zalloc for rawptr, because later on we may call free, not
1445 bfd_release, on it.
1446
1447 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1448 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1449 * cisco-core.c: New file.
1450 * Makefile.in: Change accordingly.
1451 * configure.in: Recognize cisco_core_vec.
1452 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1453 * targets.c: Add cisco_core_vec.
1454 * bfd-in2.h: Rebuilt.
1455
1456 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1457
1458 * som.h (som_copyable_section_data_struct): New structure
1459 containing all the private section information which needs
1460 to be copied from input section to output section during
1461 objcopy or strip.
1462 (som_section_data_struct): Remove several fields now in
1463 som_copyable_section_data_struct. Make the space and
1464 subspace dictionaries be pointers (to save space when
1465 only reading objects).
1466
1467 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1468 some references changed. Allocate a copyable data stucture if
1469 none exists. Store info into the copyable data structure.
1470 (bfd_som_set_subsection_attributes): Likewise.
1471 (som_is_space, som_is_subspace, som_is_container): New functions.
1472 Use these instead of directly accessing private data.
1473 (som_prep_headers): Allocate space and subspace headers here.
1474 Fill in some fields in the space/subspace headers from the
1475 copyable data.
1476 (som_bfd_copy_private_section_data): Only copy the stuff
1477 that we really need to make objcopy and strip work. Allocate
1478 the copy_data structure for the output bfd before copying.
1479
1480 * som.h (struct som_exec_data): New structure to hold exec
1481 info that must be preserved when running objcopy/strip.
1482 (struct somdata): Add new "exec_data" field and accessor
1483 macro. Add some comments on how the various fields are used.
1484 (som_section_data_struct): Make is_space and is_subspace bitfields.
1485 Delete unused subspace_index. All references now use the
1486 target_index field within the section structure itself.
1487
1488 * som.c (make_unique_section): Delete unused declaration.
1489 (som_bfd_copy_private_bfd_data): New function.
1490 (som_object_setup): Allocate space for and save exec information
1491 that needs to be copied during objcopy/strip.
1492 (som_mkobject): Do not allocate space for a file header here.
1493 It is not used when only reading SOM objects.
1494 (som_prep_headers): Allocate space for and attach a file header
1495 to the output bfd. For executables, use the saved system_id
1496 value rather than trying to guess the right value. Do not abort
1497 wwhen setting file_hdr->entry* for executables.
1498 (som_begin_writing): For executables, set the exec_entry and
1499 exec_flags fields.
1500 (som_copy_private_backend_section_data): Always return a value.
1501
1502 * libhppa.h (PA_PAGESIZE): Define.
1503
1504 * som.c (SOM_ALIGN): Define.
1505 (som_begin_writing): If writing an executable, initialize all
1506 fields in the exec header to zero. Update fields in the exec
1507 header as sizes of loadable subspaces are computed. Carefully
1508 preserve alignments when building executables. Actually write the
1509 exec after all the fields are filled in.
1510
1511 * Better long-filename handling. Reads SOM ABI compliant extended
1512 names, but doesn't quite write compliant extended names yet.
1513 * som.c (som_slurp_extended_name_table): Delete function. The
1514 generic code will handle things correctly.
1515 (som_slurp_armap): Seek to the beginning of the next member.
1516 (normalize): New function.
1517 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1518 name table into account when computing the file offsets in the
1519 SOM dictionary. Make sure to align to an even boundary.
1520 (som_write_armap): Initialize the checksum to zero.
1521 (ar_maxchars): Fix. Opps.
1522
1523 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1524
1525 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1526 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1527
1528 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1529
1530 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1531 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1532 * bfd-in2.h: Regenerated.
1533
1534 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1535 this was also named trad_unix_bfd_copy_private_bfd_data.
1536
1537 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1538
1539 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1540 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1541 returns NULL, it is not an error. It's possible that some of
1542 these checks are not necessary (because the size can never be
1543 zero), but putting in the checks is the conservative thing to do
1544 in light of the fact that some of these malloc calls replaced
1545 unchecked alloca calls, in which a zero argument would work fine.
1546
1547 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1548
1549 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1550 duplicate definition.
1551 (osf_core_bfd_is_local_label): Define.
1552
1553 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1554 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1555 failure indication, it merely means there are no relocs.
1556
1557 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1558 after NAME, since SunOS /bin/cc can't handle it.
1559
1560 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1561
1562 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1563 From sukes@glue.umd.edu (Tasuki Hirata).
1564
1565 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1566
1567 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1568 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1569 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1570
1571 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1572
1573 * som.c (som_prep_for_fixups): Detect section symbols based
1574 on either the lack of private data or the symbol flags. Do not
1575 munge section symbol names anymore -- they no longer confuse GDB.
1576 (som_begin_writing): Leave space for an exec header if writing
1577 an executable.
1578 (som_slurp_symbol_table): Recognize both forms of section symbol
1579 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1580 section symbols to be the name of the section they represent.
1581 Debugging symbols begin with "L$0\001", not just "L$".
1582
1583 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1584
1585 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1586
1587 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1588 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1589 and bfd_is_local_label.
1590
1591 * targets.c: Add new entries to the bfd_target structure.
1592
1593 * bfd.c (bfd_copy_private_bfd_data): New definition.

1596
1597 * syms.c (bfd_is_local_label): New definition.
1598
1599 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1600
1601 * libbfd.c (bfd_generic_is_local_label): New function.
1602
1603 * *-core.c: Provide default definitions for new functions in
1604 the target vector which all point to bfd_false.
1605
1606 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1607 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1608 Default new vectors for copying private backend data to bfd_true.
1609 Default new vector for determining if a symbol is a local label
1610 to bfd_generic_is_local_label.

1635
1636 * som.c (som_prep_for_fixups): A relocation involving the section

1680
1681 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1682 cruft (like the #pragma alloca for AIX).
1683 In addition to that problem, the C alloca calls xmalloc, which
1684 means checking for being out of memory can't work right. The
1685 following changes remove all uses of alloca from BFD.
1686 * hosts/solaris2.h: Remove alloca cruft.

1780 unused symbols argument.
1781
1782 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

1808 error code propogation working. Work on spacing and indention.
1809 Add FIXMEs for unresolved problems. Use enums rather than
1810 #defines for lots of things. Merge two functions which build
1811 linker stubs into a single function (so they can easily share a

1857 each case separately. Abort for bad errors until we get error
1858 code propogation working. Work on spacing and indention problems.
1859 Add FIXMEs for some unresolved problems. Delete hopelessly broken
1860 COMPLEX relocation support (it's never used anyway).

1905
1906 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

2024
2025 * section.c (bfd_get_section_contents): Since this function reads
2026 unrelocated contents, the section's raw size is always the one to
2027 use for bounds checking.
2028
2029 * linker.c (default_indirect_link_order): In assertion, compare
2030 link_order size field against cooked size, not raw size, of input
2031 section.

2036 current offset in the section plus the number of bytes of padding
2037 that will actually be retained.
2038 (b_out_relax_section): If a section contains no relocations, don't
2039 bother processing them.
2040 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2044 that reloc->addend falls between the current source offset and the
2045 raw size of the input section.
2046
2047 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
2048 bout. Default with no version number is still bout. Support
2049 explicit i960-coff target too.

2066 have any symbols.
2067
2068 * Finish basic read-write support for SOM archive libraries. Bugs
2069 surely remain as this hasn't been tested all that much.

2452
2453 * srec.c (srec_write_record): Put CONST keyword for "src" before
2454 "unsigned", some compilers don't like it after "unsigned".
2455 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
2456 "val" in prototype declaration because some compilers don't like
2457 arguments whose names are the same as types.
2458
2459 Sat Feb 5 01:14:38 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2460
2461 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

2464
2465 Fri Feb 4 23:55:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2466
2467 Add basic support for writing RS/6000 XCOFF files.

2478 fields to bitfields. Added fields fix_value and fix_scnlen.
2479 (sec_to_styp_flags): If STYP_DEBUG is defined, use it rather than
2480 STYP_INFO for the type of a section named .debug.
2481 (coff_add_missing_symbols): Don't define if RS6000COFF_C.
2482 (coff_write_object_contents): If RS6000COFF_C, don't call
2483 coff_add_missing_symbols.
2484 (coff_slurp_symbol_table): If RS6000COFF_C, then if the last aux
2485 entry has type STY_LD change the x_scnlen into a pointer to a
2486 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
2487 value into a pointer to a symbol and set fix_value.
2488 * libcoff.h: Rebuilt.
2489 * coffgen.c (coff_mangle_symbols): Reindent. If fix_value is set,
2490 get the symbol offset. Likewise for fix_scnlen.
2491 (string_size): Change type to bfd_size_type.
2492 (debug_string_size, debug_string_section): New static variables.
2493 (coff_fix_symbol_name): If bfd_coff_symname_in_debug returns true,
2494 write the symbol name into the .debug section; assume that the
2495 section has already been created with the right size.
2496 (coff_write_symbols): Initialize debug_string_size to 0. If
2497 bfd_coff_symname_in_debug returns true, don't put symbol name in
2498 usual string table. After writing out all symbols, if
2499 debug_string_size is not 0, check that it matches the size of the
2500 .debug section.
2501 (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen
2502 fields. If the string offset is 0, always use an empty string as
2503 the name.
2504 (coff_make_empty_symbol): Zero out the symbol structure.
2505 * reloc.c (bfd_perform_relocation): Work around one gross hack

2523 symbol has a value in the ECOFF symbol but not in the BFD symbol,
2524 keep the value in the ECOFF symbol. This helps gas.
2525
2526 * linker.c (_bfd_generic_link_output_symbols,
2527 _bfd_generic_link_write_global_symbol): Don't require that all
2528 references to a common symbol be themselves common symbols.

2541 and size correctly.
2542 (coff_swap_aux_in): If RS6000COFF_C, change x_csect.x_scnlen to
2543 x_csect.x_scnlen.l to match change in coff/internal.h.
2544 (coff_swap_aux_out): Likewise.
2545
2546 * coff-mips.c (mips_ecoff_backend_data), coff-alpha.c
2547 (alpha_ecoff_backend_data): Change casts of aux_in and aux_out
2548 fields to match yesterday's changes.
2549
2550 * coffcode.h (coff_write_relocs): If SELECT_RELOC is defined, pass
2551 in the internal_reloc itself, not the type.
2552 * coff-apollo.c, coff-h8300.c, coff-h8500.c, coff-i386.c,

2562 accordingly.
2563 * libcoff.h: Rebuilt.
2564 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new
2565 arguments. If RS6000COFF_C, only treat C_EXT and C_HIDEXT
2566 specially if this is the last aux entry.

2571
2572 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
2573 (only testing for m68k and vax at the moment); do verify that the
2574 preprocessor didn't trash the arch name inside the string version.
2575 Don't print out "pagesize =" line that prevents output from
2576 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
2577 results.
2578 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

2585 object file symbol.
2586
2587 Fri Jan 28 18:34:05 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2588
2589 * hosts/vaxbsd.h (HOST_STACK_END_ADDR): Vax BSD doesn't define
2590 KERNBASE, so hard-code 0x80000000 instead.

2603
2604 * som.c, som.h (bfd_som_set_section_attributes,
2605 bfd_som_set_subsection_attributes): Change parameters from char
2606 to int. Following a prototype with an old-style function definition
2607 in the presence of widened parameters is a GCC-ism not supported
2608 by the HP compiler in ANSI mode.

2615 before writing out the relocs, so that the right symbol indices
2616 are used.
2617
2618 * archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
2619 try to overlay the internal carsyms on the external symdefs. That
2620 can not work if the size of a host pointer is larger than 4 bytes.
2621
2622 * format.c (bfd_check_format_matches): Cast result of
2623 bfd_xmalloc_by_size_t.
2624 * opncls.c (_bfd_new_bfd): Avoid ANSI C prototype.

2666 .pdata section based on lnnoptr field, not section header.
2667 (alpha_relocate_section): Don't bother to check if r_symndx >= 0,

2670 coff_object_p.
2671 * ecoff.c (ecoff_new_section_hook): Set alignment_power field of
2672 .pdata section to 3.
2673 (ecoff_compute_section_file_positions): Save the size of the

2691 get the index of a common section, rather than always using
2692 SHN_COMMON (MIPS has multiple common sections).
2693
2694 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).
2695

2716 undefined, look it up in the linker hash table.
2717
2718 * aoutx.h (translate_symbol_table): The string index 0 has a
2719 special meaning for normal symbols, but not for dynamic symbols.

2736 containing the error decls that were in bfd-in.h.
2737 Remove DEFUNs.
2738 * bfd-in2.h: Regenerated.

2743 The sparc (and possibly other?) NLM format requires a different
2744 way to write exports, so add a write_export field to the backend
2745 data (and set it to NULL for everything but the sparc).
2746
2747 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2748
2749 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,

2761 to be unused.
2762 * bfd-in2.h: Regenerated.
2763

2788 (NAME(aout,get_reloc_upper_bound)): Include dynamic reloc count in
2789 return value.
2790 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
2791 out dynamic symbols or relocs against reloc symbols, since they
2792 are already in the .text section and we wouldn't know where to
2793 write them anyhow.
2794 (sunos4_aout_backend): Initialize read_dynamic_symbols and
2795 read_dynamic_relocs fields.
2796 * aout-target.h (MY(backend_data)): Initialize
2797 read_dynamic_symbols and read_dynamic_relocs fields.

2800
2801 * hosts/alphaosf.h (uint64e_type, uint64_type, int64_type): Delete

2987 * configure.in (nlm32_alpha_vec): Set target64 to true.
2988
2989 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are

4001
4002 * config.bfd: Use bigmips for mips*-*-bsd*.
4003
4004 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4005
4006 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
4007 Handle symbol number of zero.
4008
4009 * reloc.c (enum bfd_reloc_code_real): Added
4010 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
4011 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
4012 * bfd-in2.h: Rebuilt.
4013 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
4014 BFD_RELOC_MIPS_LITERAL.
4015 * elf32-mips.c (mips_reloc_map): Handle new relocs.
4016 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
4017 checks slightly.
4018
4019 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
4020 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
4021 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
4022 MY_bfd_seclet_link): Define.
4023 (MY_bfd_reloc_type_lookup): Rename from
4024 MY_reloc_howto_type_lookup.
4025 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
4026 (MY(vec)): Use JUMP_TABLE rather than listing functions.
4027 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
4028 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
4029 terms of MY, because that causes a recusive invocation of CAT when
4030 expanded within JUMP_TABLE, and ANSI compilers don't expand
4031 recursive macros.
4032 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
4033 MY_reloc_howto_type_lookup, and don't define in terms of MY.
4034 (MY_canonicalize_reloc): Don't define in terms of MY.
4035 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
4036 than listing functions.
