1331 add_symbls entry point.
1333 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1334 counting relocs. Set SEC_RELOC flag for any section which has

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.
1344 (generic_link_add_symbols): New function, like old
1345 _bfd_generic_link_add_symbols but with collect argument.
1346 (generic_link_add_object_symbols): Take collect argument.

1358 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1359 for first character in an extended name.
1360 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1361 "//" as the name of the special archive member holding the
1362 extended name table.
1364 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1366 Support for link_order types which generate relocs in order to
1367 support -Ur in the linker.
1368 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1369 from call to _bfd_generic_link_add_one_symbol.
1370 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1371 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
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,
1378 (_bfd_count_link_order_relocs): New function.
1379 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
1380 argument from declaration.
1381 (_bfd_generic_reloc_link_order): Declare.
1382 (_bfd_count_link_order_relocs): Declare.
1383 * libbfd.h: Rebuilt.
1384 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
1385 call to _bfd_generic_link_add_one_symbol.
1386 (NAME(aout,final_link)): Account for link_order relocs when

1391 call to _bfd_generic_link_add_one_symbol.
1392 (ecoff_bfd_final_link): Account for link_order relocs when
1393 allocating space for relocations. Handle them in link_order loop.
1394 (ecoff_link_write_external): Set the storage class of a defined
1395 linker created symbol based on the section it is in. Correct
1396 bfd_link_hash_weak case to use .sc rather than .st.
1397 (ecoff_reloc_link_order): New function.
1398 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1400 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1405 * cisco-core.c (cisco_core_file_p): Only pass one argument to
1406 bfd_zmalloc. Free a pointer, not a union.
1407 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1409 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1411 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1413 * som.c (bfd_section_from_som_symbol): Only to do the value
1414 comparison for function symbols within executables.
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.)
1423 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
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.)
1430 * som.c (som_begin_writing): Align text in all executables to
1431 make HPUX kernel happy. Fixes strip/objcopy for shared
1434 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
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.
1441 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
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
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.
1456 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
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
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).
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
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.
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.
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
1500 (som_copy_private_backend_section_data): Always return a value.
1502 * libhppa.h (PA_PAGESIZE): Define.
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.
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.
1523 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
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.
1528 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
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.
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.
1537 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
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.
1547 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1549 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1550 duplicate definition.
1551 (osf_core_bfd_is_local_label): Define.
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.
1557 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1558 after NAME, since SunOS /bin/cc can't handle it.
1560 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1562 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1563 From sukes@glue.umd.edu (Tasuki Hirata).
1565 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
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).
1571 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
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
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$0\001", not just "L$".
1583 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1585 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
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.
1591 * targets.c: Add new entries to the bfd_target structure.
1593 * bfd.c (bfd_copy_private_bfd_data): New definition.
1595 * section.c (bfd_copy_private_section_data): New definition.
1597 * syms.c (bfd_is_local_label): New definition.
1599 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1601 * libbfd.c (bfd_generic_is_local_label): New function.
1603 * *-core.c: Provide default definitions for new functions in
1604 the target vector which all point to bfd_false.
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.
1612 * som.c (som_bfd_copy_private_section_data): New function.
1613 (som_bfd_is_local_label): New function.
1614 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1616 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1618 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1620 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1622 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1625 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1626 Indent some of them to GNU standards.
1628 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1629 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1630 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1631 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1632 Update copyright years.
1634 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1636 * som.c (som_prep_for_fixups): A relocation involving the section
1637 symbol for the *ABS* section is really a relocation involving
1639 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1640 undefined symbols. Correctly distinguish between debugger symbols
1641 and section symbols.
1643 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1644 for spaces and subspaces.
1646 * som.c (som_bfd_count_ar_symbols): Fix typo.
1648 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1649 HAS_RELOC based on the object's magic number.
1650 (make_unique_section): Delete function. BFD and its users are
1651 prepared to handle multiple sections with the same name.
1652 (setup_sections): Allocate space on the BFD's obstack to hold
1653 section names. Use bfd_make_setion_anyway rather than the
1654 obsolete make_unique_section.
1655 (som_prep_headers): Choose the correct SOM magic number based
1657 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1659 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

1673 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1674 is always located at the start of the data section to allow
1675 recovery of the dynamic info from a stripped executable.
1676 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1679 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
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.
1687 * som.c: Replace alloca with a fixed size auto array.

1692 * linker.c: Replace alloca with obstack_alloc.
1693 * libbfd.h: Rebuilt.
1695 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1697 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1700 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1702 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1703 Elf*_Off typedefs by their expansion, the typedefs have been
1704 removed from include/elf/internal.h.
1705 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1706 SHT_PROGBITS section.
1708 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1710 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1714 * configure.host: Recognize i[34]86-sequent-*.
1716 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1717 return from bfd_seek indicates an error.
1718 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1719 TRAD_CORE_STACK_OFFSET.
1720 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1721 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1723 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1725 * som.[ch]: Do not include libhppa.h in som.c, instead include
1728 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1729 include it in elf32-hppa.h.
1731 * som.c (log2): Return -1 on error rather than aborting.
1732 (setup_sections): Bubble up an error from log2.
1734 * Changes to make HP C compiler happy in both traditional
1736 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1738 (bfd_som_set_section_attributes): Use unsigned int rather than
1739 unsigned char to avoid GNU-C extensions.
1740 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1741 or failure rather than aborting on failure.
1743 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1745 (bfd_som_attach_aux_hdr): Add prototype.
1746 (hppa_som-gen_reloc_type): Likewise.

1749 (hppa_look_for_stubs_in_section): Do not return false on failure
1750 until rest of code is ready to handle it. Abort for now.
1752 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1754 * bfd-in2.h: Rebuilt.
1756 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

1762 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
1764 * config.bfd : Add i386-os9k.

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

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).

4030 expanded within JUMP_TABLE, and ANSI compilers don't expand
4032 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
4033 MY_reloc_howto_type_lookup, and don't define in terms of MY.
