1739 required by expansions. Set s and unset h when converting a reloc
1740 from undefined to section. Change handling of PC relative relocs:
1741 if against a section, they are correct in the object file, if
1742 against an external symbol they are pcrel_offset.

1874 Support for link_order types which generate relocs in order to
1875 support -Ur in the linker.
1876 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1877 from call to _bfd_generic_link_add_one_symbol.
1878 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1879 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1880 instead of bitsize to add_to_set call back.
1881 (_bfd_generic_final_link): Account for link_order relocs when
1882 allocating space for relocations. Handle them in link_order loop.

1901 allocating space for relocations. Handle them in link_order loop.
1902 (ecoff_link_write_external): Set the storage class of a defined
1903 linker created symbol based on the section it is in. Correct
1904 bfd_link_hash_weak case to use .sc rather than .st.
1905 (ecoff_reloc_link_order): New function.
1906 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

1922 comparison for function symbols within executables.
1924 * som.c (bfd_section_from_som_symbol): Renamed from
1925 som_section_from_subspace_index. Pass in a native SOM symbol.
1926 For executables, iterate through the sections to find out
1927 which contains the symbol's address rather than using the
1928 symbol_info field. (symbol_info has a different meaning for
1929 dynamicly linked executables.)
1931 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1934 * som.c (som_begin_writing): Fix braino (one call to align
1935 space/subspace data was done unconditionally rather than
1936 just for executables.)
1938 * som.c (som_begin_writing): Align text in all executables to
1939 make HPUX kernel happy. Fixes strip/objcopy for shared
1942 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1944 * som.c (som_begin_writing): Account for alignment needs of
1945 subspaces too when writing executables. Never request a negative
1946 bss size. Fixes some problems with demand paged executables,
1947 still having problems with pure executables and shared executables.
1949 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1951 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1952 bfd_zalloc for rawptr, because later on we may call free, not
1955 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1956 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1957 * cisco-core.c: New file.

1966 * som.h (som_copyable_section_data_struct): New structure
1967 containing all the private section information which needs
1968 to be copied from input section to output section during
1970 (som_section_data_struct): Remove several fields now in
1971 som_copyable_section_data_struct. Make the space and
1972 subspace dictionaries be pointers (to save space when
1973 only reading objects).
1975 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1976 some references changed. Allocate a copyable data stucture if
1977 none exists. Store info into the copyable data structure.
1978 (bfd_som_set_subsection_attributes): Likewise.
1979 (som_is_space, som_is_subspace, som_is_container): New functions.
1980 Use these instead of directly accessing private data.
1981 (som_prep_headers): Allocate space and subspace headers here.
1982 Fill in some fields in the space/subspace headers from the
1984 (som_bfd_copy_private_section_data): Only copy the stuff
1985 that we really need to make objcopy and strip work. Allocate
1986 the copy_data structure for the output bfd before copying.
1988 * som.h (struct som_exec_data): New structure to hold exec
1989 info that must be preserved when running objcopy/strip.
1990 (struct somdata): Add new "exec_data" field and accessor
1991 macro. Add some comments on how the various fields are used.
1992 (som_section_data_struct): Make is_space and is_subspace bitfields.
1993 Delete unused subspace_index. All references now use the
1994 target_index field within the section structure itself.
1996 * som.c (make_unique_section): Delete unused declaration.
1997 (som_bfd_copy_private_bfd_data): New function.
1998 (som_object_setup): Allocate space for and save exec information
1999 that needs to be copied during objcopy/strip.
2000 (som_mkobject): Do not allocate space for a file header here.
2001 It is not used when only reading SOM objects.
2002 (som_prep_headers): Allocate space for and attach a file header
2003 to the output bfd. For executables, use the saved system_id
2004 value rather than trying to guess the right value. Do not abort
2005 wwhen setting file_hdr->entry* for executables.
2006 (som_begin_writing): For executables, set the exec_entry and
2008 (som_copy_private_backend_section_data): Always return a value.
2010 * libhppa.h (PA_PAGESIZE): Define.
2012 * som.c (SOM_ALIGN): Define.
2013 (som_begin_writing): If writing an executable, initialize all
2014 fields in the exec header to zero. Update fields in the exec
2015 header as sizes of loadable subspaces are computed. Carefully
2016 preserve alignments when building executables. Actually write the
2017 exec after all the fields are filled in.
2019 * Better long-filename handling. Reads SOM ABI compliant extended
2020 names, but doesn't quite write compliant extended names yet.
2021 * som.c (som_slurp_extended_name_table): Delete function. The
2022 generic code will handle things correctly.
2023 (som_slurp_armap): Seek to the beginning of the next member.
2024 (normalize): New function.
2025 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2026 name table into account when computing the file offsets in the
2027 SOM dictionary. Make sure to align to an even boundary.
2028 (som_write_armap): Initialize the checksum to zero.
2029 (ar_maxchars): Fix. Opps.

2038 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2039 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2040 * bfd-in2.h: Regenerated.
2042 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2043 this was also named trad_unix_bfd_copy_private_bfd_data.
2045 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2047 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2048 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2049 returns NULL, it is not an error. It's possible that some of
2050 these checks are not necessary (because the size can never be
2051 zero), but putting in the checks is the conservative thing to do
2052 in light of the fact that some of these malloc calls replaced
2053 unchecked alloca calls, in which a zero argument would work fine.
2055 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2057 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2058 duplicate definition.
2059 (osf_core_bfd_is_local_label): Define.
2061 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2062 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2063 failure indication, it merely means there are no relocs.
2065 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2066 after NAME, since SunOS /bin/cc can't handle it.
2068 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2070 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2071 From sukes@glue.umd.edu (Tasuki Hirata).
2073 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2075 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2076 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2077 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2079 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2081 * som.c (som_prep_for_fixups): Detect section symbols based
2082 on either the lack of private data or the symbol flags. Do not
2083 munge section symbol names anymore -- they no longer confuse GDB.
2084 (som_begin_writing): Leave space for an exec header if writing
2086 (som_slurp_symbol_table): Recognize both forms of section symbol
2087 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2088 section symbols to be the name of the section they represent.
2089 Debugging symbols begin with "L$0\001", not just "L$".
2091 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2093 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2095 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2096 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2097 and bfd_is_local_label.

2115 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2116 Default new vectors for copying private backend data to bfd_true.
2117 Default new vector for determining if a symbol is a local label
2118 to bfd_generic_is_local_label.
2120 * som.c (som_bfd_copy_private_section_data): New function.
2121 (som_bfd_is_local_label): New function.
2122 (som_bfd_copy_private_bfd_data): For now default to bfd_true.

2126 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2128 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2130 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2133 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2134 Indent some of them to GNU standards.
2136 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2137 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2139 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2140 Update copyright years.
2142 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2144 * som.c (som_prep_for_fixups): A relocation involving the section
2145 symbol for the *ABS* section is really a relocation involving
2147 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2148 undefined symbols. Correctly distinguish between debugger symbols
2149 and section symbols.
2151 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2152 for spaces and subspaces.
2154 * som.c (som_bfd_count_ar_symbols): Fix typo.
2156 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2157 HAS_RELOC based on the object's magic number.
2158 (make_unique_section): Delete function. BFD and its users are
2159 prepared to handle multiple sections with the same name.
2160 (setup_sections): Allocate space on the BFD's obstack to hold
2161 section names. Use bfd_make_setion_anyway rather than the
2162 obsolete make_unique_section.
2163 (som_prep_headers): Choose the correct SOM magic number based
2165 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

2188 cruft (like the #pragma alloca for AIX).
2189 In addition to that problem, the C alloca calls xmalloc, which
2190 means checking for being out of memory can't work right. The
2191 following changes remove all uses of alloca from BFD.

2540 that will actually be retained.
2541 (b_out_relax_section): If a section contains no relocations, don't
2542 bother processing them.
2543 (b_out_get_relocated_section_contents): Set reloc_done. Assert
2544 that bfd_get_section_contents returns true. Check that relocs are

2547 that reloc->addend falls between the current source offset and the
2548 raw size of the input section.

2627 Make all callers of malloc or realloc (including via obstacks)
2628 check the result for NULL. Most set bfd_error to no_memory and
2629 return in that case; a few are harder to fix, and are marked

3076 (only testing for m68k and vax at the moment); do verify that the
3077 preprocessor didn't trash the arch name inside the string version.

3219 undefined, look it up in the linker hash table.
3221 * aoutx.h (translate_symbol_table): The string index 0 has a

3246 The sparc (and possibly other?) NLM format requires a different
3247 way to write exports, so add a write_export field to the backend
3248 data (and set it to NULL for everything but the sparc).

3409 * ecofflink.c: Extensive changes to compress and merge debugging
3410 information, and to write some of out directly rather than saving

3414 sym_filepos as well.
3415 (ecoff_get_extr): Use ifdmap instead of ifdbase.

3485 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
3487 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

3490 * configure.in (nlm32_alpha_vec): Set target64 to true.
3492 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
3493 different, so there is no point to providing a generic one.
3494 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
3495 in the backend accessor macros; that should no longer be possible.
3496 * targets.c (target_vector): Removed nlm32_big_generic_vec,
3497 nlm64_big_generic_vec, nlm64_little_generic_vec.

4385 of architectures, get the ELF EM_xxx code from the backend
4386 information. Let the generic ELF target match any EM_xxx code not
4387 matched by another ELF target. Call elf_backend_object_p to let
4388 the backend do more checks and set global information.
4389 * libelf.h (struct elf_backend_data): Added elf_machine_code and
4390 elf_backend_object_p fields.
4391 (struct bfd_elf_arch_map): Removed.

4393 * elf32-target.h, elf64-target.h: Initialize elf_machine_code
4394 field with ELF_MACHINE_CODE. Initialize elf_backend_object_p
4395 field with elf_backend_object_p (if it is defined).

4412 * elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
4413 for R_MIPS_26. Correct overflow detection requires matching the
4414 upper four bits of the destination against the PC. From Ted Lemon
4415 <mellon@pepper.ncd.com>.
4417 * bout.c (b_out_reloc_type_lookup): Return type should point to
4419 * coff-i960.c (coff_i960_reloc_type_lookup): Likewise.
4420 * elf32-hppa.c (elf_hppa_reloc_type_lookup): Likewise.

4427 field. Removed unused write_relocs field.
4428 * elf32-target.h: Adjusted elf_backend_data initialization
4430 * elf64-target.h: Corrected elf_backend_data initialization to
4431 fill in all fields and to set elf_64_p to 1.
4433 Mon Nov 8 18:13:14 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
