1314 for any section which has relocs. Handle link_order relocs in
1315 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1316 add_symbls entry point.
1318 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1319 counting relocs. Set SEC_RELOC flag for any section which has
1322 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
1324 * linker.c (_bfd_generic_link_add_symbols): Just call
1325 generic_link_add_symbols.
1326 (_bfd_generic_link_add_symbols_collect): New function, like
1327 _bfd_generic_link_add_symbols but also collect constructors and
1328 destructors by name as collect2 does.
1329 (generic_link_add_symbols): New function, like old
1330 _bfd_generic_link_add_symbols but with collect argument.
1331 (generic_link_add_object_symbols): Take collect argument.

1343 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1344 for first character in an extended name.
1345 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1346 "//" as the name of the special archive member holding the
1347 extended name table.
1349 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1351 Support for link_order types which generate relocs in order to
1352 support -Ur in the linker.
1353 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1354 from call to _bfd_generic_link_add_one_symbol.
1355 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1356 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1357 instead of bitsize to add_to_set call back.
1358 (_bfd_generic_final_link): Account for link_order relocs when
1359 allocating space for relocations. Handle them in link_order loop.
1360 (_bfd_generic_reloc_link_order): New function.
1361 (_bfd_default_link_order): If a reloc_link_order is seen here,
1363 (_bfd_count_link_order_relocs): New function.
1364 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
1365 argument from declaration.
1366 (_bfd_generic_reloc_link_order): Declare.
1367 (_bfd_count_link_order_relocs): Declare.
1368 * libbfd.h: Rebuilt.
1369 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
1370 call to _bfd_generic_link_add_one_symbol.
1371 (NAME(aout,final_link)): Account for link_order relocs when

1376 call to _bfd_generic_link_add_one_symbol.
1377 (ecoff_bfd_final_link): Account for link_order relocs when
1378 allocating space for relocations. Handle them in link_order loop.
1379 (ecoff_link_write_external): Set the storage class of a defined
1380 linker created symbol based on the section it is in. Correct
1381 bfd_link_hash_weak case to use .sc rather than .st.
1382 (ecoff_reloc_link_order): New function.
1383 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1385 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
1387 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
1390 * cisco-core.c (cisco_core_file_p): Only pass one argument to
1391 bfd_zmalloc. Free a pointer, not a union.
1392 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1394 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1396 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1398 * som.c (bfd_section_from_som_symbol): Only to do the value
1399 comparison for function symbols within executables.
1401 * som.c (bfd_section_from_som_symbol): Renamed from
1402 som_section_from_subspace_index. Pass in a native SOM symbol.
1403 For executables, iterate through the sections to find out
1404 which contains the symbol's address rather than using the
1405 symbol_info field. (symbol_info has a different meaning for
1406 dynamicly linked executables.)
1408 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1411 * som.c (som_begin_writing): Fix braino (one call to align
1412 space/subspace data was done unconditionally rather than
1413 just for executables.)
1415 * som.c (som_begin_writing): Align text in all executables to
1416 make HPUX kernel happy. Fixes strip/objcopy for shared
1419 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1421 * som.c (som_begin_writing): Account for alignment needs of
1422 subspaces too when writing executables. Never request a negative
1423 bss size. Fixes some problems with demand paged executables,
1424 still having problems with pure executables and shared executables.
1426 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1428 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1429 bfd_zalloc for rawptr, because later on we may call free, not
1432 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1433 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1434 * cisco-core.c: New file.
1435 * Makefile.in: Change accordingly.
1436 * configure.in: Recognize cisco_core_vec.
1437 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1438 * targets.c: Add cisco_core_vec.
1439 * bfd-in2.h: Rebuilt.
1441 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1443 * som.h (som_copyable_section_data_struct): New structure
1444 containing all the private section information which needs
1445 to be copied from input section to output section during
1447 (som_section_data_struct): Remove several fields now in
1448 som_copyable_section_data_struct. Make the space and
1449 subspace dictionaries be pointers (to save space when
1450 only reading objects).
1452 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1453 some references changed. Allocate a copyable data stucture if
1454 none exists. Store info into the copyable data structure.
1455 (bfd_som_set_subsection_attributes): Likewise.
1456 (som_is_space, som_is_subspace, som_is_container): New functions.
1457 Use these instead of directly accessing private data.
1458 (som_prep_headers): Allocate space and subspace headers here.
1459 Fill in some fields in the space/subspace headers from the
1461 (som_bfd_copy_private_section_data): Only copy the stuff
1462 that we really need to make objcopy and strip work. Allocate
1463 the copy_data structure for the output bfd before copying.
1465 * som.h (struct som_exec_data): New structure to hold exec
1466 info that must be preserved when running objcopy/strip.
1467 (struct somdata): Add new "exec_data" field and accessor
1468 macro. Add some comments on how the various fields are used.
1469 (som_section_data_struct): Make is_space and is_subspace bitfields.
1470 Delete unused subspace_index. All references now use the
1471 target_index field within the section structure itself.
1473 * som.c (make_unique_section): Delete unused declaration.
1474 (som_bfd_copy_private_bfd_data): New function.
1475 (som_object_setup): Allocate space for and save exec information
1476 that needs to be copied during objcopy/strip.
1477 (som_mkobject): Do not allocate space for a file header here.
1478 It is not used when only reading SOM objects.
1479 (som_prep_headers): Allocate space for and attach a file header
1480 to the output bfd. For executables, use the saved system_id
1481 value rather than trying to guess the right value. Do not abort
1482 wwhen setting file_hdr->entry* for executables.
1483 (som_begin_writing): For executables, set the exec_entry and
1485 (som_copy_private_backend_section_data): Always return a value.
1487 * libhppa.h (PA_PAGESIZE): Define.
1489 * som.c (SOM_ALIGN): Define.
1490 (som_begin_writing): If writing an executable, initialize all
1491 fields in the exec header to zero. Update fields in the exec
1492 header as sizes of loadable subspaces are computed. Carefully
1493 preserve alignments when building executables. Actually write the
1494 exec after all the fields are filled in.
1496 * Better long-filename handling. Reads SOM ABI compliant extended
1497 names, but doesn't quite write compliant extended names yet.
1498 * som.c (som_slurp_extended_name_table): Delete function. The
1499 generic code will handle things correctly.
1500 (som_slurp_armap): Seek to the beginning of the next member.
1501 (normalize): New function.
1502 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1503 name table into account when computing the file offsets in the
1504 SOM dictionary. Make sure to align to an even boundary.
1505 (som_write_armap): Initialize the checksum to zero.
1506 (ar_maxchars): Fix. Opps.
1508 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1510 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1511 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1513 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1515 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1516 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1517 * bfd-in2.h: Regenerated.
1519 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1520 this was also named trad_unix_bfd_copy_private_bfd_data.
1522 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1524 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1525 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1526 returns NULL, it is not an error. It's possible that some of
1527 these checks are not necessary (because the size can never be
1528 zero), but putting in the checks is the conservative thing to do
1529 in light of the fact that some of these malloc calls replaced
1530 unchecked alloca calls, in which a zero argument would work fine.
1532 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1534 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1535 duplicate definition.
1536 (osf_core_bfd_is_local_label): Define.
1538 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1539 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1540 failure indication, it merely means there are no relocs.
1542 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1543 after NAME, since SunOS /bin/cc can't handle it.
1545 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1547 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1548 From sukes@glue.umd.edu (Tasuki Hirata).
1550 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1552 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1553 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1554 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1556 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1558 * som.c (som_prep_for_fixups): Detect section symbols based
1559 on either the lack of private data or the symbol flags. Do not
1560 munge section symbol names anymore -- they no longer confuse GDB.
1561 (som_begin_writing): Leave space for an exec header if writing
1563 (som_slurp_symbol_table): Recognize both forms of section symbol
1564 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1565 section symbols to be the name of the section they represent.
1566 Debugging symbols begin with "L$0\001", not just "L$".
1568 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1570 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1572 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1573 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1574 and bfd_is_local_label.
1576 * targets.c: Add new entries to the bfd_target structure.
1578 * bfd.c (bfd_copy_private_bfd_data): New definition.
1580 * section.c (bfd_copy_private_section_data): New definition.
1582 * syms.c (bfd_is_local_label): New definition.
1584 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1586 * libbfd.c (bfd_generic_is_local_label): New function.
1588 * *-core.c: Provide default definitions for new functions in
1589 the target vector which all point to bfd_false.
1591 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1592 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1593 Default new vectors for copying private backend data to bfd_true.
1594 Default new vector for determining if a symbol is a local label
1595 to bfd_generic_is_local_label.
1597 * som.c (som_bfd_copy_private_section_data): New function.
1598 (som_bfd_is_local_label): New function.
1599 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1601 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1603 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1605 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1607 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1610 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1611 Indent some of them to GNU standards.
1613 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1614 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1615 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1616 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1617 Update copyright years.
1619 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1621 * som.c (som_prep_for_fixups): A relocation involving the section
1622 symbol for the *ABS* section is really a relocation involving
1624 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1625 undefined symbols. Correctly distinguish between debugger symbols
1626 and section symbols.
1628 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1629 for spaces and subspaces.
1631 * som.c (som_bfd_count_ar_symbols): Fix typo.
1633 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1634 HAS_RELOC based on the object's magic number.
1635 (make_unique_section): Delete function. BFD and its users are
1636 prepared to handle multiple sections with the same name.
1637 (setup_sections): Allocate space on the BFD's obstack to hold
1638 section names. Use bfd_make_setion_anyway rather than the
1639 obsolete make_unique_section.
1640 (som_prep_headers): Choose the correct SOM magic number based
1642 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1644 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

1658 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1659 is always located at the start of the data section to allow
1660 recovery of the dynamic info from a stripped executable.
1661 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1664 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1666 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1667 cruft (like the #pragma alloca for AIX).
1668 In addition to that problem, the C alloca calls xmalloc, which
1669 means checking for being out of memory can't work right. The
1670 following changes remove all uses of alloca from BFD.
1671 * hosts/solaris2.h: Remove alloca cruft.
1672 * som.c: Replace alloca with a fixed size auto array.

1685 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1687 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1688 Elf*_Off typedefs by their expansion, the typedefs have been
1689 removed from include/elf/internal.h.
1690 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1691 SHT_PROGBITS section.

1701 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1702 return from bfd_seek indicates an error.
1703 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1704 TRAD_CORE_STACK_OFFSET.
1705 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1706 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1708 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1710 * som.[ch]: Do not include libhppa.h in som.c, instead include
1713 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1714 include it in elf32-hppa.h.
1716 * som.c (log2): Return -1 on error rather than aborting.
1717 (setup_sections): Bubble up an error from log2.
1719 * Changes to make HP C compiler happy in both traditional
1721 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1723 (bfd_som_set_section_attributes): Use unsigned int rather than
1724 unsigned char to avoid GNU-C extensions.
1725 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1726 or failure rather than aborting on failure.
1728 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1730 (bfd_som_attach_aux_hdr): Add prototype.
1731 (hppa_som-gen_reloc_type): Likewise.

1760 action in case where caller specified no argument relocation.
1761 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
1762 right in the original relocation and the stub's relocation.
1764 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
1765 unused symbols argument.

1770 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
1771 (hppa_elf_look_for_stubs_in_section): No longer need symbols
1772 argument. Use the output symbols when canonicalizing the relocs,
1773 creating them if necessary.

1794 Add FIXMEs for unresolved problems. Use enums rather than
1795 #defines for lots of things. Merge two functions which build
1796 linker stubs into a single function (so they can easily share a

1845 COMPLEX relocation support (it's never used anyway).
1846 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

2022 that will actually be retained.
2023 (b_out_relax_section): If a section contains no relocations, don't
2024 bother processing them.
2025 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2037 fixed some comments, removed some "#if 1" lines.

3967 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
3968 in last change. Always rebuild symbol extension section the first
3969 time though if output sections exist (fixes ld -r problems).
3971 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)
3973 * Makefile.in: Add .PHONY for check and installcheck rules.
3975 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
3977 * libbfd-in.h (artdata): Use long, not time_t for portability, at
3978 least to HPUX. File below is a derived file.
3980 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
3982 * libbfd.h (artdata): Use long, not time_t for portability, at
3985 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
3987 * config.bfd: Use bigmips for mips*-*-bsd*.
3989 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3991 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
3992 Handle symbol number of zero.
3994 * reloc.c (enum bfd_reloc_code_real): Added
3995 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
3996 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
3997 * bfd-in2.h: Rebuilt.
3998 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
3999 BFD_RELOC_MIPS_LITERAL.
4000 * elf32-mips.c (mips_reloc_map): Handle new relocs.
4001 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
4004 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
4005 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
4006 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
4007 MY_bfd_seclet_link): Define.
4008 (MY_bfd_reloc_type_lookup): Rename from
4009 MY_reloc_howto_type_lookup.
4010 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
4011 (MY(vec)): Use JUMP_TABLE rather than listing functions.
4012 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
4013 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
4014 terms of MY, because that causes a recusive invocation of CAT when
4015 expanded within JUMP_TABLE, and ANSI compilers don't expand
4017 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
4018 MY_reloc_howto_type_lookup, and don't define in terms of MY.
4019 (MY_canonicalize_reloc): Don't define in terms of MY.
4020 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
4021 than listing functions.
