1770 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1772 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
1773 reloc, used in embedded PIC code.
1774 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1782 add_symbls entry point.
1784 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1785 counting relocs. Set SEC_RELOC flag for any section which has

1791 generic_link_add_symbols.
1792 (_bfd_generic_link_add_symbols_collect): New function, like
1793 _bfd_generic_link_add_symbols but also collect constructors and
1794 destructors by name as collect2 does.
1795 (generic_link_add_symbols): New function, like old
1796 _bfd_generic_link_add_symbols but with collect argument.
1797 (generic_link_add_object_symbols): Take collect argument.

1809 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1810 for first character in an extended name.
1811 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1812 "//" as the name of the special archive member holding the
1813 extended name table.
1815 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1817 Support for link_order types which generate relocs in order to
1818 support -Ur in the linker.
1819 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1820 from call to _bfd_generic_link_add_one_symbol.
1821 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1822 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1823 instead of bitsize to add_to_set call back.
1824 (_bfd_generic_final_link): Account for link_order relocs when
1825 allocating space for relocations. Handle them in link_order loop.
1826 (_bfd_generic_reloc_link_order): New function.

1842 call to _bfd_generic_link_add_one_symbol.
1843 (ecoff_bfd_final_link): Account for link_order relocs when
1844 allocating space for relocations. Handle them in link_order loop.
1845 (ecoff_link_write_external): Set the storage class of a defined
1846 linker created symbol based on the section it is in. Correct
1847 bfd_link_hash_weak case to use .sc rather than .st.
1848 (ecoff_reloc_link_order): New function.
1849 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

1860 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1862 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1864 * som.c (bfd_section_from_som_symbol): Only to do the value
1865 comparison for function symbols within executables.
1867 * som.c (bfd_section_from_som_symbol): Renamed from
1868 som_section_from_subspace_index. Pass in a native SOM symbol.
1869 For executables, iterate through the sections to find out
1870 which contains the symbol's address rather than using the
1871 symbol_info field. (symbol_info has a different meaning for
1872 dynamicly linked executables.)
1874 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1877 * som.c (som_begin_writing): Fix braino (one call to align
1878 space/subspace data was done unconditionally rather than
1879 just for executables.)
1881 * som.c (som_begin_writing): Align text in all executables to
1882 make HPUX kernel happy. Fixes strip/objcopy for shared
1885 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1887 * som.c (som_begin_writing): Account for alignment needs of
1888 subspaces too when writing executables. Never request a negative
1889 bss size. Fixes some problems with demand paged executables,
1890 still having problems with pure executables and shared executables.
1892 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1894 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1895 bfd_zalloc for rawptr, because later on we may call free, not
1898 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1899 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1900 * cisco-core.c: New file.
1901 * Makefile.in: Change accordingly.
1902 * configure.in: Recognize cisco_core_vec.
1903 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1904 * targets.c: Add cisco_core_vec.
1905 * bfd-in2.h: Rebuilt.
1907 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1909 * som.h (som_copyable_section_data_struct): New structure
1910 containing all the private section information which needs
1911 to be copied from input section to output section during
1913 (som_section_data_struct): Remove several fields now in
1914 som_copyable_section_data_struct. Make the space and
1915 subspace dictionaries be pointers (to save space when
1916 only reading objects).
1918 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1919 some references changed. Allocate a copyable data stucture if
1920 none exists. Store info into the copyable data structure.
1921 (bfd_som_set_subsection_attributes): Likewise.
1922 (som_is_space, som_is_subspace, som_is_container): New functions.
1923 Use these instead of directly accessing private data.
1924 (som_prep_headers): Allocate space and subspace headers here.
1925 Fill in some fields in the space/subspace headers from the
1927 (som_bfd_copy_private_section_data): Only copy the stuff
1928 that we really need to make objcopy and strip work. Allocate
1929 the copy_data structure for the output bfd before copying.
1931 * som.h (struct som_exec_data): New structure to hold exec
1932 info that must be preserved when running objcopy/strip.
1933 (struct somdata): Add new "exec_data" field and accessor
1934 macro. Add some comments on how the various fields are used.
1935 (som_section_data_struct): Make is_space and is_subspace bitfields.
1936 Delete unused subspace_index. All references now use the
1937 target_index field within the section structure itself.
1939 * som.c (make_unique_section): Delete unused declaration.
1940 (som_bfd_copy_private_bfd_data): New function.
1941 (som_object_setup): Allocate space for and save exec information
1942 that needs to be copied during objcopy/strip.
1943 (som_mkobject): Do not allocate space for a file header here.
1944 It is not used when only reading SOM objects.
1945 (som_prep_headers): Allocate space for and attach a file header
1946 to the output bfd. For executables, use the saved system_id
1947 value rather than trying to guess the right value. Do not abort
1948 wwhen setting file_hdr->entry* for executables.
1949 (som_begin_writing): For executables, set the exec_entry and
1951 (som_copy_private_backend_section_data): Always return a value.
1953 * libhppa.h (PA_PAGESIZE): Define.
1955 * som.c (SOM_ALIGN): Define.
1956 (som_begin_writing): If writing an executable, initialize all
1957 fields in the exec header to zero. Update fields in the exec
1958 header as sizes of loadable subspaces are computed. Carefully
1959 preserve alignments when building executables. Actually write the
1960 exec after all the fields are filled in.
1962 * Better long-filename handling. Reads SOM ABI compliant extended
1963 names, but doesn't quite write compliant extended names yet.
1964 * som.c (som_slurp_extended_name_table): Delete function. The
1965 generic code will handle things correctly.
1966 (som_slurp_armap): Seek to the beginning of the next member.
1967 (normalize): New function.
1968 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1969 name table into account when computing the file offsets in the
1970 SOM dictionary. Make sure to align to an even boundary.
1971 (som_write_armap): Initialize the checksum to zero.
1972 (ar_maxchars): Fix. Opps.
1974 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1976 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1977 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1979 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1981 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1982 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1983 * bfd-in2.h: Regenerated.
1985 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1986 this was also named trad_unix_bfd_copy_private_bfd_data.
1988 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1990 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1991 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1992 returns NULL, it is not an error. It's possible that some of
1993 these checks are not necessary (because the size can never be
1994 zero), but putting in the checks is the conservative thing to do
1995 in light of the fact that some of these malloc calls replaced
1996 unchecked alloca calls, in which a zero argument would work fine.
1998 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2000 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2001 duplicate definition.
2002 (osf_core_bfd_is_local_label): Define.
2004 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2005 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2006 failure indication, it merely means there are no relocs.
2008 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2009 after NAME, since SunOS /bin/cc can't handle it.
2011 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2013 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2014 From sukes@glue.umd.edu (Tasuki Hirata).
2016 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2018 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2019 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2020 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2022 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2024 * som.c (som_prep_for_fixups): Detect section symbols based
2025 on either the lack of private data or the symbol flags. Do not
2026 munge section symbol names anymore -- they no longer confuse GDB.
2027 (som_begin_writing): Leave space for an exec header if writing
2029 (som_slurp_symbol_table): Recognize both forms of section symbol
2030 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2031 section symbols to be the name of the section they represent.
2032 Debugging symbols begin with "L$0\001", not just "L$".
2034 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2036 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2038 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2039 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2040 and bfd_is_local_label.
2042 * targets.c: Add new entries to the bfd_target structure.
2044 * bfd.c (bfd_copy_private_bfd_data): New definition.
2046 * section.c (bfd_copy_private_section_data): New definition.
2048 * syms.c (bfd_is_local_label): New definition.
2050 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2052 * libbfd.c (bfd_generic_is_local_label): New function.
2054 * *-core.c: Provide default definitions for new functions in
2055 the target vector which all point to bfd_false.
2057 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2058 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2059 Default new vectors for copying private backend data to bfd_true.
2060 Default new vector for determining if a symbol is a local label
2061 to bfd_generic_is_local_label.
2063 * som.c (som_bfd_copy_private_section_data): New function.
2064 (som_bfd_is_local_label): New function.
2065 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2067 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2069 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2071 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2073 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2076 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2077 Indent some of them to GNU standards.
2079 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2080 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2081 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2082 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2083 Update copyright years.
2085 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2087 * som.c (som_prep_for_fixups): A relocation involving the section
2088 symbol for the *ABS* section is really a relocation involving
2090 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2091 undefined symbols. Correctly distinguish between debugger symbols
2092 and section symbols.
2094 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2095 for spaces and subspaces.
2097 * som.c (som_bfd_count_ar_symbols): Fix typo.
2099 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2100 HAS_RELOC based on the object's magic number.
2101 (make_unique_section): Delete function. BFD and its users are
2102 prepared to handle multiple sections with the same name.
2103 (setup_sections): Allocate space on the BFD's obstack to hold
2104 section names. Use bfd_make_setion_anyway rather than the
2105 obsolete make_unique_section.
2106 (som_prep_headers): Choose the correct SOM magic number based
2108 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2110 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2112 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2122 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2123 is always located at the start of the data section to allow
2124 recovery of the dynamic info from a stripped executable.
2125 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2128 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2130 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2131 cruft (like the #pragma alloca for AIX).
2132 In addition to that problem, the C alloca calls xmalloc, which
2133 means checking for being out of memory can't work right. The
2134 following changes remove all uses of alloca from BFD.
2135 * hosts/solaris2.h: Remove alloca cruft.
2136 * som.c: Replace alloca with a fixed size auto array.

2141 * linker.c: Replace alloca with obstack_alloc.
2142 * libbfd.h: Rebuilt.
2144 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2146 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2149 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2151 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2152 Elf*_Off typedefs by their expansion, the typedefs have been
2153 removed from include/elf/internal.h.
2154 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2155 SHT_PROGBITS section.
2157 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2159 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2163 * configure.host: Recognize i[34]86-sequent-*.
2165 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2166 return from bfd_seek indicates an error.
2167 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2168 TRAD_CORE_STACK_OFFSET.
2169 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2170 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2172 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2174 * som.[ch]: Do not include libhppa.h in som.c, instead include
2177 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2178 include it in elf32-hppa.h.
2180 * som.c (log2): Return -1 on error rather than aborting.

2484 (b_out_relax_section): If a section contains no relocations, don't
2485 bother processing them.
2486 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3189 The sparc (and possibly other?) NLM format requires a different
3190 way to write exports, so add a write_export field to the backend
3191 data (and set it to NULL for everything but the sparc).
