1336 add_symbls entry point.
1338 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1339 counting relocs. Set SEC_RELOC flag for any section which has

1345 generic_link_add_symbols.
1346 (_bfd_generic_link_add_symbols_collect): New function, like
1347 _bfd_generic_link_add_symbols but also collect constructors and
1348 destructors by name as collect2 does.
1349 (generic_link_add_symbols): New function, like old
1350 _bfd_generic_link_add_symbols but with collect argument.
1351 (generic_link_add_object_symbols): Take collect argument.

1363 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1364 for first character in an extended name.
1365 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1366 "//" as the name of the special archive member holding the
1367 extended name table.
1369 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1371 Support for link_order types which generate relocs in order to
1372 support -Ur in the linker.
1373 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1374 from call to _bfd_generic_link_add_one_symbol.
1375 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1376 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1377 instead of bitsize to add_to_set call back.
1378 (_bfd_generic_final_link): Account for link_order relocs when
1379 allocating space for relocations. Handle them in link_order loop.
1380 (_bfd_generic_reloc_link_order): New function.

1383 (_bfd_count_link_order_relocs): New function.
1384 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
1385 argument from declaration.
1386 (_bfd_generic_reloc_link_order): Declare.
1387 (_bfd_count_link_order_relocs): Declare.

1389 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
1390 call to _bfd_generic_link_add_one_symbol.

1396 call to _bfd_generic_link_add_one_symbol.
1397 (ecoff_bfd_final_link): Account for link_order relocs when
1398 allocating space for relocations. Handle them in link_order loop.
1399 (ecoff_link_write_external): Set the storage class of a defined
1400 linker created symbol based on the section it is in. Correct
1401 bfd_link_hash_weak case to use .sc rather than .st.
1402 (ecoff_reloc_link_order): New function.
1403 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1405 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1414 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1416 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1418 * som.c (bfd_section_from_som_symbol): Only to do the value
1419 comparison for function symbols within executables.
1421 * som.c (bfd_section_from_som_symbol): Renamed from
1422 som_section_from_subspace_index. Pass in a native SOM symbol.
1423 For executables, iterate through the sections to find out
1424 which contains the symbol's address rather than using the
1425 symbol_info field. (symbol_info has a different meaning for
1426 dynamicly linked executables.)
1428 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1431 * som.c (som_begin_writing): Fix braino (one call to align
1432 space/subspace data was done unconditionally rather than
1433 just for executables.)
1435 * som.c (som_begin_writing): Align text in all executables to
1436 make HPUX kernel happy. Fixes strip/objcopy for shared
1439 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1441 * som.c (som_begin_writing): Account for alignment needs of
1442 subspaces too when writing executables. Never request a negative
1443 bss size. Fixes some problems with demand paged executables,
1444 still having problems with pure executables and shared executables.
1446 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1448 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1449 bfd_zalloc for rawptr, because later on we may call free, not
1452 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1453 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1454 * cisco-core.c: New file.
1455 * Makefile.in: Change accordingly.
1456 * configure.in: Recognize cisco_core_vec.
1457 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1458 * targets.c: Add cisco_core_vec.
1459 * bfd-in2.h: Rebuilt.
1461 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1463 * som.h (som_copyable_section_data_struct): New structure
1464 containing all the private section information which needs
1465 to be copied from input section to output section during
1467 (som_section_data_struct): Remove several fields now in
1468 som_copyable_section_data_struct. Make the space and
1469 subspace dictionaries be pointers (to save space when
1470 only reading objects).
1472 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1473 some references changed. Allocate a copyable data stucture if
1474 none exists. Store info into the copyable data structure.
1475 (bfd_som_set_subsection_attributes): Likewise.
1476 (som_is_space, som_is_subspace, som_is_container): New functions.
1477 Use these instead of directly accessing private data.
1478 (som_prep_headers): Allocate space and subspace headers here.
1479 Fill in some fields in the space/subspace headers from the
1481 (som_bfd_copy_private_section_data): Only copy the stuff
1482 that we really need to make objcopy and strip work. Allocate
1483 the copy_data structure for the output bfd before copying.
1485 * som.h (struct som_exec_data): New structure to hold exec
1486 info that must be preserved when running objcopy/strip.
1487 (struct somdata): Add new "exec_data" field and accessor
1488 macro. Add some comments on how the various fields are used.
1489 (som_section_data_struct): Make is_space and is_subspace bitfields.
1490 Delete unused subspace_index. All references now use the
1491 target_index field within the section structure itself.
1493 * som.c (make_unique_section): Delete unused declaration.
1494 (som_bfd_copy_private_bfd_data): New function.
1495 (som_object_setup): Allocate space for and save exec information
1496 that needs to be copied during objcopy/strip.
1497 (som_mkobject): Do not allocate space for a file header here.
1498 It is not used when only reading SOM objects.
1499 (som_prep_headers): Allocate space for and attach a file header
1500 to the output bfd. For executables, use the saved system_id
1501 value rather than trying to guess the right value. Do not abort
1502 wwhen setting file_hdr->entry* for executables.
1503 (som_begin_writing): For executables, set the exec_entry and
1505 (som_copy_private_backend_section_data): Always return a value.
1507 * libhppa.h (PA_PAGESIZE): Define.
1509 * som.c (SOM_ALIGN): Define.
1510 (som_begin_writing): If writing an executable, initialize all
1511 fields in the exec header to zero. Update fields in the exec
1512 header as sizes of loadable subspaces are computed. Carefully
1513 preserve alignments when building executables. Actually write the
1514 exec after all the fields are filled in.
1516 * Better long-filename handling. Reads SOM ABI compliant extended
1517 names, but doesn't quite write compliant extended names yet.
1518 * som.c (som_slurp_extended_name_table): Delete function. The
1519 generic code will handle things correctly.
1520 (som_slurp_armap): Seek to the beginning of the next member.
1521 (normalize): New function.
1522 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1523 name table into account when computing the file offsets in the
1524 SOM dictionary. Make sure to align to an even boundary.
1525 (som_write_armap): Initialize the checksum to zero.
1526 (ar_maxchars): Fix. Opps.
1528 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1530 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1531 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1533 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1535 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1536 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1537 * bfd-in2.h: Regenerated.
1539 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1540 this was also named trad_unix_bfd_copy_private_bfd_data.
1542 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1544 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1545 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1546 returns NULL, it is not an error. It's possible that some of
1547 these checks are not necessary (because the size can never be
1548 zero), but putting in the checks is the conservative thing to do
1549 in light of the fact that some of these malloc calls replaced
1550 unchecked alloca calls, in which a zero argument would work fine.
1552 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1554 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1555 duplicate definition.
1556 (osf_core_bfd_is_local_label): Define.
1558 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1559 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1560 failure indication, it merely means there are no relocs.
1562 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1563 after NAME, since SunOS /bin/cc can't handle it.
1565 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1567 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1568 From sukes@glue.umd.edu (Tasuki Hirata).
1570 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1572 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1573 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1574 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1576 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1578 * som.c (som_prep_for_fixups): Detect section symbols based
1579 on either the lack of private data or the symbol flags. Do not
1580 munge section symbol names anymore -- they no longer confuse GDB.
1581 (som_begin_writing): Leave space for an exec header if writing
1583 (som_slurp_symbol_table): Recognize both forms of section symbol
1584 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1585 section symbols to be the name of the section they represent.
1586 Debugging symbols begin with "L$0\001", not just "L$".
1588 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1590 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1592 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1593 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1594 and bfd_is_local_label.
1596 * targets.c: Add new entries to the bfd_target structure.
1598 * bfd.c (bfd_copy_private_bfd_data): New definition.

1608 * *-core.c: Provide default definitions for new functions in
1609 the target vector which all point to bfd_false.

1612 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1613 Default new vectors for copying private backend data to bfd_true.
1614 Default new vector for determining if a symbol is a local label
1615 to bfd_generic_is_local_label.
1617 * som.c (som_bfd_copy_private_section_data): New function.
1618 (som_bfd_is_local_label): New function.
1619 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1621 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1623 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1625 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1627 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1630 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1631 Indent some of them to GNU standards.
1633 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1634 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1635 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1636 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1637 Update copyright years.
1639 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1641 * som.c (som_prep_for_fixups): A relocation involving the section
1642 symbol for the *ABS* section is really a relocation involving
1644 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1645 undefined symbols. Correctly distinguish between debugger symbols
1646 and section symbols.
1648 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1649 for spaces and subspaces.
1651 * som.c (som_bfd_count_ar_symbols): Fix typo.
1653 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1654 HAS_RELOC based on the object's magic number.
1655 (make_unique_section): Delete function. BFD and its users are
1656 prepared to handle multiple sections with the same name.
1657 (setup_sections): Allocate space on the BFD's obstack to hold
1658 section names. Use bfd_make_setion_anyway rather than the
1659 obsolete make_unique_section.
1660 (som_prep_headers): Choose the correct SOM magic number based
1662 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1664 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1666 * elf32-ppc.c: Renamed from elf32-powerpc.c.

1678 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1679 is always located at the start of the data section to allow
1680 recovery of the dynamic info from a stripped executable.
1681 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1684 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1686 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1687 cruft (like the #pragma alloca for AIX).
1688 In addition to that problem, the C alloca calls xmalloc, which
1689 means checking for being out of memory can't work right. The
1690 following changes remove all uses of alloca from BFD.
1691 * hosts/solaris2.h: Remove alloca cruft.
1692 * som.c: Replace alloca with a fixed size auto array.

1697 * linker.c: Replace alloca with obstack_alloc.
1698 * libbfd.h: Rebuilt.
1700 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1702 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1705 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1707 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1708 Elf*_Off typedefs by their expansion, the typedefs have been
1709 removed from include/elf/internal.h.
1710 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1711 SHT_PROGBITS section.
1713 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1715 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1719 * configure.host: Recognize i[34]86-sequent-*.
1721 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1722 return from bfd_seek indicates an error.
1723 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1724 TRAD_CORE_STACK_OFFSET.
1725 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1726 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1728 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1730 * som.[ch]: Do not include libhppa.h in som.c, instead include
1733 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1734 include it in elf32-hppa.h.
1736 * som.c (log2): Return -1 on error rather than aborting.
1737 (setup_sections): Bubble up an error from log2.
1739 * Changes to make HP C compiler happy in both traditional
1741 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1743 (bfd_som_set_section_attributes): Use unsigned int rather than
1744 unsigned char to avoid GNU-C extensions.
1745 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1746 or failure rather than aborting on failure.
1748 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1750 (bfd_som_attach_aux_hdr): Add prototype.
1751 (hppa_som-gen_reloc_type): Likewise.

1754 (hppa_look_for_stubs_in_section): Do not return false on failure
1755 until rest of code is ready to handle it. Abort for now.
1757 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1759 * bfd-in2.h: Rebuilt.
1761 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

2042 that will actually be retained.
2043 (b_out_relax_section): If a section contains no relocations, don't
2044 bother processing them.
2045 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2748 The sparc (and possibly other?) NLM format requires a different
2749 way to write exports, so add a write_export field to the backend
2750 data (and set it to NULL for everything but the sparc).
