1336 required by expansions. Set s and unset h when converting a reloc
1337 from undefined to section. Change handling of PC relative relocs:
1338 if against a section, they are correct in the object file, if
1339 against an external symbol they are pcrel_offset.
1340 (mips_relax_section): New function.
1341 (mips_relax_pcrel16): New function.

1427 reloc, used in embedded PIC code.
1428 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1436 add_symbls entry point.
1438 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1439 counting relocs. Set SEC_RELOC flag for any section which has

1467 extended name table.
1469 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1471 Support for link_order types which generate relocs in order to
1472 support -Ur in the linker.
1473 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1474 from call to _bfd_generic_link_add_one_symbol.
1475 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1476 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1477 instead of bitsize to add_to_set call back.
1478 (_bfd_generic_final_link): Account for link_order relocs when
1479 allocating space for relocations. Handle them in link_order loop.
1480 (_bfd_generic_reloc_link_order): New function.

1497 (ecoff_bfd_final_link): Account for link_order relocs when
1498 allocating space for relocations. Handle them in link_order loop.
1499 (ecoff_link_write_external): Set the storage class of a defined
1500 linker created symbol based on the section it is in. Correct
1501 bfd_link_hash_weak case to use .sc rather than .st.
1502 (ecoff_reloc_link_order): New function.
1503 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1505 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1510 * cisco-core.c (cisco_core_file_p): Only pass one argument to
1511 bfd_zmalloc. Free a pointer, not a union.
1512 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1514 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1516 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1518 * som.c (bfd_section_from_som_symbol): Only to do the value
1519 comparison for function symbols within executables.
1521 * som.c (bfd_section_from_som_symbol): Renamed from
1522 som_section_from_subspace_index. Pass in a native SOM symbol.
1523 For executables, iterate through the sections to find out
1524 which contains the symbol's address rather than using the
1525 symbol_info field. (symbol_info has a different meaning for
1526 dynamicly linked executables.)
1528 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1531 * som.c (som_begin_writing): Fix braino (one call to align
1532 space/subspace data was done unconditionally rather than
1533 just for executables.)
1535 * som.c (som_begin_writing): Align text in all executables to
1536 make HPUX kernel happy. Fixes strip/objcopy for shared
1539 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1541 * som.c (som_begin_writing): Account for alignment needs of
1542 subspaces too when writing executables. Never request a negative
1543 bss size. Fixes some problems with demand paged executables,
1544 still having problems with pure executables and shared executables.
1546 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1548 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1549 bfd_zalloc for rawptr, because later on we may call free, not
1552 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1553 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1554 * cisco-core.c: New file.
1555 * Makefile.in: Change accordingly.
1556 * configure.in: Recognize cisco_core_vec.
1557 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1558 * targets.c: Add cisco_core_vec.
1559 * bfd-in2.h: Rebuilt.
1561 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1563 * som.h (som_copyable_section_data_struct): New structure
1564 containing all the private section information which needs
1565 to be copied from input section to output section during
1567 (som_section_data_struct): Remove several fields now in
1568 som_copyable_section_data_struct. Make the space and
1569 subspace dictionaries be pointers (to save space when
1570 only reading objects).
1572 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1573 some references changed. Allocate a copyable data stucture if
1574 none exists. Store info into the copyable data structure.
1575 (bfd_som_set_subsection_attributes): Likewise.
1576 (som_is_space, som_is_subspace, som_is_container): New functions.
1577 Use these instead of directly accessing private data.
1578 (som_prep_headers): Allocate space and subspace headers here.
1579 Fill in some fields in the space/subspace headers from the
1581 (som_bfd_copy_private_section_data): Only copy the stuff
1582 that we really need to make objcopy and strip work. Allocate
1583 the copy_data structure for the output bfd before copying.
1585 * som.h (struct som_exec_data): New structure to hold exec
1586 info that must be preserved when running objcopy/strip.
1587 (struct somdata): Add new "exec_data" field and accessor
1588 macro. Add some comments on how the various fields are used.
1589 (som_section_data_struct): Make is_space and is_subspace bitfields.
1590 Delete unused subspace_index. All references now use the
1591 target_index field within the section structure itself.
1593 * som.c (make_unique_section): Delete unused declaration.
1594 (som_bfd_copy_private_bfd_data): New function.
1595 (som_object_setup): Allocate space for and save exec information
1596 that needs to be copied during objcopy/strip.
1597 (som_mkobject): Do not allocate space for a file header here.
1598 It is not used when only reading SOM objects.
1599 (som_prep_headers): Allocate space for and attach a file header
1600 to the output bfd. For executables, use the saved system_id
1601 value rather than trying to guess the right value. Do not abort
1602 wwhen setting file_hdr->entry* for executables.
1603 (som_begin_writing): For executables, set the exec_entry and
1605 (som_copy_private_backend_section_data): Always return a value.
1607 * libhppa.h (PA_PAGESIZE): Define.
1609 * som.c (SOM_ALIGN): Define.
1610 (som_begin_writing): If writing an executable, initialize all
1611 fields in the exec header to zero. Update fields in the exec
1612 header as sizes of loadable subspaces are computed. Carefully
1613 preserve alignments when building executables. Actually write the
1614 exec after all the fields are filled in.
1616 * Better long-filename handling. Reads SOM ABI compliant extended
1617 names, but doesn't quite write compliant extended names yet.
1618 * som.c (som_slurp_extended_name_table): Delete function. The
1619 generic code will handle things correctly.
1620 (som_slurp_armap): Seek to the beginning of the next member.
1621 (normalize): New function.
1622 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1623 name table into account when computing the file offsets in the
1624 SOM dictionary. Make sure to align to an even boundary.
1625 (som_write_armap): Initialize the checksum to zero.
1626 (ar_maxchars): Fix. Opps.
1628 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1630 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1631 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1633 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1635 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1636 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1637 * bfd-in2.h: Regenerated.
1639 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1640 this was also named trad_unix_bfd_copy_private_bfd_data.
1642 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1644 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1645 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1646 returns NULL, it is not an error. It's possible that some of
1647 these checks are not necessary (because the size can never be
1648 zero), but putting in the checks is the conservative thing to do
1649 in light of the fact that some of these malloc calls replaced
1650 unchecked alloca calls, in which a zero argument would work fine.
1652 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1654 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1655 duplicate definition.
1656 (osf_core_bfd_is_local_label): Define.
1658 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1659 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1660 failure indication, it merely means there are no relocs.
1662 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1663 after NAME, since SunOS /bin/cc can't handle it.
1665 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1667 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1668 From sukes@glue.umd.edu (Tasuki Hirata).
1670 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1672 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1673 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1674 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1676 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1678 * som.c (som_prep_for_fixups): Detect section symbols based
1679 on either the lack of private data or the symbol flags. Do not
1680 munge section symbol names anymore -- they no longer confuse GDB.
1681 (som_begin_writing): Leave space for an exec header if writing
1683 (som_slurp_symbol_table): Recognize both forms of section symbol
1684 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1685 section symbols to be the name of the section they represent.
1686 Debugging symbols begin with "L$0\001", not just "L$".
1688 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1690 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1692 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1693 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1694 and bfd_is_local_label.
1696 * targets.c: Add new entries to the bfd_target structure.

1709 the target vector which all point to bfd_false.
1711 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1712 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1713 Default new vectors for copying private backend data to bfd_true.
1714 Default new vector for determining if a symbol is a local label
1715 to bfd_generic_is_local_label.
1717 * som.c (som_bfd_copy_private_section_data): New function.
1718 (som_bfd_is_local_label): New function.
1719 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1721 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1723 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1725 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1727 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1730 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1731 Indent some of them to GNU standards.
1733 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1734 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1735 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1736 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1737 Update copyright years.
1739 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1741 * som.c (som_prep_for_fixups): A relocation involving the section
1742 symbol for the *ABS* section is really a relocation involving
1744 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1745 undefined symbols. Correctly distinguish between debugger symbols
1746 and section symbols.
1748 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1749 for spaces and subspaces.
1751 * som.c (som_bfd_count_ar_symbols): Fix typo.
1753 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1754 HAS_RELOC based on the object's magic number.

1785 cruft (like the #pragma alloca for AIX).
1786 In addition to that problem, the C alloca calls xmalloc, which

2672 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
2673 (only testing for m68k and vax at the moment); do verify that the
2674 preprocessor didn't trash the arch name inside the string version.
2675 Don't print out "pagesize =" line that prevents output from
2676 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
2678 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

2705 bfd_som_set_subsection_attributes): Change parameters from char
2706 to int. Following a prototype with an old-style function definition

2810 (get_value): If the symbol is undefined, look it up in the linker
2812 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
2813 use get_value to get the symbol value and check for undefined
2815 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
2816 undefined, look it up in the linker hash table.
2818 * aoutx.h (translate_symbol_table): The string index 0 has a

2843 The sparc (and possibly other?) NLM format requires a different
2844 way to write exports, so add a write_export field to the backend
2845 data (and set it to NULL for everything but the sparc).

3006 * ecofflink.c: Extensive changes to compress and merge debugging
3007 information, and to write some of out directly rather than saving

3011 sym_filepos as well.
3012 (ecoff_get_extr): Use ifdmap instead of ifdbase.

3078 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
3079 count it as a wrong format error, not a system call error, since
3080 the object file might simply be too small.
3082 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
3084 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

3087 * configure.in (nlm32_alpha_vec): Set target64 to true.
3089 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are

3981 * elfcode.h (elf_object_p): Rather than looking through an array
3982 of architectures, get the ELF EM_xxx code from the backend
