1792 in asymbol udata field.
1794 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1796 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
1797 reloc, used in embedded PIC code.

1817 _bfd_generic_link_add_symbols but also collect constructors and
1818 destructors by name as collect2 does.

1837 extended name table.
1839 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1841 Support for link_order types which generate relocs in order to
1842 support -Ur in the linker.
1843 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1844 from call to _bfd_generic_link_add_one_symbol.
1845 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1846 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1847 instead of bitsize to add_to_set call back.
1848 (_bfd_generic_final_link): Account for link_order relocs when
1849 allocating space for relocations. Handle them in link_order loop.
1850 (_bfd_generic_reloc_link_order): New function.

1868 allocating space for relocations. Handle them in link_order loop.
1869 (ecoff_link_write_external): Set the storage class of a defined
1870 linker created symbol based on the section it is in. Correct
1871 bfd_link_hash_weak case to use .sc rather than .st.

1889 comparison for function symbols within executables.
1891 * som.c (bfd_section_from_som_symbol): Renamed from
1892 som_section_from_subspace_index. Pass in a native SOM symbol.
1893 For executables, iterate through the sections to find out
1894 which contains the symbol's address rather than using the
1895 symbol_info field. (symbol_info has a different meaning for
1896 dynamicly linked executables.)
1898 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1901 * som.c (som_begin_writing): Fix braino (one call to align
1902 space/subspace data was done unconditionally rather than
1903 just for executables.)
1905 * som.c (som_begin_writing): Align text in all executables to
1906 make HPUX kernel happy. Fixes strip/objcopy for shared
1909 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1911 * som.c (som_begin_writing): Account for alignment needs of
1912 subspaces too when writing executables. Never request a negative
1913 bss size. Fixes some problems with demand paged executables,
1914 still having problems with pure executables and shared executables.
1916 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1918 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1919 bfd_zalloc for rawptr, because later on we may call free, not
1922 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1923 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1924 * cisco-core.c: New file.
1925 * Makefile.in: Change accordingly.
1926 * configure.in: Recognize cisco_core_vec.
1927 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1928 * targets.c: Add cisco_core_vec.

1931 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1933 * som.h (som_copyable_section_data_struct): New structure
1934 containing all the private section information which needs
1935 to be copied from input section to output section during
1937 (som_section_data_struct): Remove several fields now in
1938 som_copyable_section_data_struct. Make the space and
1939 subspace dictionaries be pointers (to save space when
1940 only reading objects).
1942 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1943 some references changed. Allocate a copyable data stucture if
1944 none exists. Store info into the copyable data structure.
1945 (bfd_som_set_subsection_attributes): Likewise.
1946 (som_is_space, som_is_subspace, som_is_container): New functions.
1947 Use these instead of directly accessing private data.
1948 (som_prep_headers): Allocate space and subspace headers here.
1949 Fill in some fields in the space/subspace headers from the
1951 (som_bfd_copy_private_section_data): Only copy the stuff
1952 that we really need to make objcopy and strip work. Allocate
1953 the copy_data structure for the output bfd before copying.
1955 * som.h (struct som_exec_data): New structure to hold exec
1956 info that must be preserved when running objcopy/strip.
1957 (struct somdata): Add new "exec_data" field and accessor
1958 macro. Add some comments on how the various fields are used.
1959 (som_section_data_struct): Make is_space and is_subspace bitfields.
1960 Delete unused subspace_index. All references now use the
1961 target_index field within the section structure itself.
1963 * som.c (make_unique_section): Delete unused declaration.
1964 (som_bfd_copy_private_bfd_data): New function.
1965 (som_object_setup): Allocate space for and save exec information
1966 that needs to be copied during objcopy/strip.
1967 (som_mkobject): Do not allocate space for a file header here.
1968 It is not used when only reading SOM objects.
1969 (som_prep_headers): Allocate space for and attach a file header
1970 to the output bfd. For executables, use the saved system_id
1971 value rather than trying to guess the right value. Do not abort
1972 wwhen setting file_hdr->entry* for executables.
1973 (som_begin_writing): For executables, set the exec_entry and
1975 (som_copy_private_backend_section_data): Always return a value.
1977 * libhppa.h (PA_PAGESIZE): Define.
1979 * som.c (SOM_ALIGN): Define.
1980 (som_begin_writing): If writing an executable, initialize all
1981 fields in the exec header to zero. Update fields in the exec
1982 header as sizes of loadable subspaces are computed. Carefully
1983 preserve alignments when building executables. Actually write the
1984 exec after all the fields are filled in.
1986 * Better long-filename handling. Reads SOM ABI compliant extended
1987 names, but doesn't quite write compliant extended names yet.
1988 * som.c (som_slurp_extended_name_table): Delete function. The
1989 generic code will handle things correctly.
1990 (som_slurp_armap): Seek to the beginning of the next member.
1991 (normalize): New function.
1992 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1993 name table into account when computing the file offsets in the
1994 SOM dictionary. Make sure to align to an even boundary.
1995 (som_write_armap): Initialize the checksum to zero.
1996 (ar_maxchars): Fix. Opps.
1998 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2000 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2001 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2003 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2005 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2006 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2007 * bfd-in2.h: Regenerated.
2009 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2010 this was also named trad_unix_bfd_copy_private_bfd_data.
2012 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2014 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2015 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2016 returns NULL, it is not an error. It's possible that some of
2017 these checks are not necessary (because the size can never be
2018 zero), but putting in the checks is the conservative thing to do
2019 in light of the fact that some of these malloc calls replaced
2020 unchecked alloca calls, in which a zero argument would work fine.
2022 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2024 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2025 duplicate definition.
2026 (osf_core_bfd_is_local_label): Define.
2028 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2029 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2030 failure indication, it merely means there are no relocs.
2032 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2033 after NAME, since SunOS /bin/cc can't handle it.
2035 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2037 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2038 From sukes@glue.umd.edu (Tasuki Hirata).
2040 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2042 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2043 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2044 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2046 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2048 * som.c (som_prep_for_fixups): Detect section symbols based
2049 on either the lack of private data or the symbol flags. Do not
2050 munge section symbol names anymore -- they no longer confuse GDB.
2051 (som_begin_writing): Leave space for an exec header if writing
2053 (som_slurp_symbol_table): Recognize both forms of section symbol
2054 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2055 section symbols to be the name of the section they represent.
2056 Debugging symbols begin with "L$0\001", not just "L$".
2058 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2060 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2062 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2063 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2064 and bfd_is_local_label.
2066 * targets.c: Add new entries to the bfd_target structure.
2068 * bfd.c (bfd_copy_private_bfd_data): New definition.
2070 * section.c (bfd_copy_private_section_data): New definition.
2072 * syms.c (bfd_is_local_label): New definition.
2074 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2076 * libbfd.c (bfd_generic_is_local_label): New function.
2078 * *-core.c: Provide default definitions for new functions in
2079 the target vector which all point to bfd_false.
2081 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2082 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2083 Default new vectors for copying private backend data to bfd_true.
2084 Default new vector for determining if a symbol is a local label
2085 to bfd_generic_is_local_label.
2087 * som.c (som_bfd_copy_private_section_data): New function.
2088 (som_bfd_is_local_label): New function.
2089 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2091 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2093 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2095 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2097 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2100 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2101 Indent some of them to GNU standards.
2103 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2104 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2105 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2106 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2107 Update copyright years.
2109 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2111 * som.c (som_prep_for_fixups): A relocation involving the section
2112 symbol for the *ABS* section is really a relocation involving
2114 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2115 undefined symbols. Correctly distinguish between debugger symbols
2116 and section symbols.
2118 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2119 for spaces and subspaces.
2121 * som.c (som_bfd_count_ar_symbols): Fix typo.
2123 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2124 HAS_RELOC based on the object's magic number.
2125 (make_unique_section): Delete function. BFD and its users are
2126 prepared to handle multiple sections with the same name.
2127 (setup_sections): Allocate space on the BFD's obstack to hold
2128 section names. Use bfd_make_setion_anyway rather than the
2129 obsolete make_unique_section.
2130 (som_prep_headers): Choose the correct SOM magic number based
2132 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2134 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2136 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2146 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2147 is always located at the start of the data section to allow
2148 recovery of the dynamic info from a stripped executable.
2149 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2152 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2154 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2155 cruft (like the #pragma alloca for AIX).
2156 In addition to that problem, the C alloca calls xmalloc, which
2157 means checking for being out of memory can't work right. The
2158 following changes remove all uses of alloca from BFD.
2159 * hosts/solaris2.h: Remove alloca cruft.
2160 * som.c: Replace alloca with a fixed size auto array.

2165 * linker.c: Replace alloca with obstack_alloc.
2166 * libbfd.h: Rebuilt.
2168 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2170 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2173 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2175 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2176 Elf*_Off typedefs by their expansion, the typedefs have been
2177 removed from include/elf/internal.h.
2178 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like

2509 bother processing them.
2510 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3213 The sparc (and possibly other?) NLM format requires a different
3214 way to write exports, so add a write_export field to the backend
3215 data (and set it to NULL for everything but the sparc).

3459 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
3460 different, so there is no point to providing a generic one.
