1738 (_bfd_generic_final_link): Likewise.
1739 (_bfd_generic_link_output_symbols): Likewise.

1742 in asymbol udata field.
1744 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1746 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
1747 reloc, used in embedded PIC code.

1755 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1756 add_symbls entry point.
1758 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1759 counting relocs. Set SEC_RELOC flag for any section which has

1764 * linker.c (_bfd_generic_link_add_symbols): Just call
1765 generic_link_add_symbols.
1766 (_bfd_generic_link_add_symbols_collect): New function, like
1767 _bfd_generic_link_add_symbols but also collect constructors and
1768 destructors by name as collect2 does.
1769 (generic_link_add_symbols): New function, like old
1770 _bfd_generic_link_add_symbols but with collect argument.
1771 (generic_link_add_object_symbols): Take collect argument.

1783 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1784 for first character in an extended name.
1785 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1786 "//" as the name of the special archive member holding the
1787 extended name table.
1789 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1791 Support for link_order types which generate relocs in order to
1792 support -Ur in the linker.
1793 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1794 from call to _bfd_generic_link_add_one_symbol.
1795 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1796 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1797 instead of bitsize to add_to_set call back.
1798 (_bfd_generic_final_link): Account for link_order relocs when
1799 allocating space for relocations. Handle them in link_order loop.
1800 (_bfd_generic_reloc_link_order): New function.
1801 (_bfd_default_link_order): If a reloc_link_order is seen here,
1803 (_bfd_count_link_order_relocs): New function.
1804 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
1805 argument from declaration.
1806 (_bfd_generic_reloc_link_order): Declare.
1807 (_bfd_count_link_order_relocs): Declare.
1808 * libbfd.h: Rebuilt.
1809 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
1810 call to _bfd_generic_link_add_one_symbol.
1811 (NAME(aout,final_link)): Account for link_order relocs when

1816 call to _bfd_generic_link_add_one_symbol.
1817 (ecoff_bfd_final_link): Account for link_order relocs when
1818 allocating space for relocations. Handle them in link_order loop.
1819 (ecoff_link_write_external): Set the storage class of a defined
1820 linker created symbol based on the section it is in. Correct
1821 bfd_link_hash_weak case to use .sc rather than .st.
1822 (ecoff_reloc_link_order): New function.
1823 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1825 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1834 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1836 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1838 * som.c (bfd_section_from_som_symbol): Only to do the value
1839 comparison for function symbols within executables.
1841 * som.c (bfd_section_from_som_symbol): Renamed from
1842 som_section_from_subspace_index. Pass in a native SOM symbol.
1843 For executables, iterate through the sections to find out
1844 which contains the symbol's address rather than using the
1845 symbol_info field. (symbol_info has a different meaning for
1846 dynamicly linked executables.)
1848 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1851 * som.c (som_begin_writing): Fix braino (one call to align
1852 space/subspace data was done unconditionally rather than
1853 just for executables.)
1855 * som.c (som_begin_writing): Align text in all executables to
1856 make HPUX kernel happy. Fixes strip/objcopy for shared
1859 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1861 * som.c (som_begin_writing): Account for alignment needs of
1862 subspaces too when writing executables. Never request a negative
1863 bss size. Fixes some problems with demand paged executables,
1864 still having problems with pure executables and shared executables.
1866 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1868 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1869 bfd_zalloc for rawptr, because later on we may call free, not
1872 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1873 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1874 * cisco-core.c: New file.
1875 * Makefile.in: Change accordingly.
1876 * configure.in: Recognize cisco_core_vec.
1877 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1878 * targets.c: Add cisco_core_vec.
1879 * bfd-in2.h: Rebuilt.
1881 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1883 * som.h (som_copyable_section_data_struct): New structure
1884 containing all the private section information which needs
1885 to be copied from input section to output section during
1887 (som_section_data_struct): Remove several fields now in
1888 som_copyable_section_data_struct. Make the space and
1889 subspace dictionaries be pointers (to save space when
1890 only reading objects).
1892 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1893 some references changed. Allocate a copyable data stucture if
1894 none exists. Store info into the copyable data structure.
1895 (bfd_som_set_subsection_attributes): Likewise.
1896 (som_is_space, som_is_subspace, som_is_container): New functions.
1897 Use these instead of directly accessing private data.
1898 (som_prep_headers): Allocate space and subspace headers here.
1899 Fill in some fields in the space/subspace headers from the
1901 (som_bfd_copy_private_section_data): Only copy the stuff
1902 that we really need to make objcopy and strip work. Allocate
1903 the copy_data structure for the output bfd before copying.
1905 * som.h (struct som_exec_data): New structure to hold exec
1906 info that must be preserved when running objcopy/strip.
1907 (struct somdata): Add new "exec_data" field and accessor
1908 macro. Add some comments on how the various fields are used.
1909 (som_section_data_struct): Make is_space and is_subspace bitfields.
1910 Delete unused subspace_index. All references now use the
1911 target_index field within the section structure itself.
1913 * som.c (make_unique_section): Delete unused declaration.
1914 (som_bfd_copy_private_bfd_data): New function.
1915 (som_object_setup): Allocate space for and save exec information
1916 that needs to be copied during objcopy/strip.
1917 (som_mkobject): Do not allocate space for a file header here.
1918 It is not used when only reading SOM objects.
1919 (som_prep_headers): Allocate space for and attach a file header
1920 to the output bfd. For executables, use the saved system_id
1921 value rather than trying to guess the right value. Do not abort
1922 wwhen setting file_hdr->entry* for executables.
1923 (som_begin_writing): For executables, set the exec_entry and
1925 (som_copy_private_backend_section_data): Always return a value.
1927 * libhppa.h (PA_PAGESIZE): Define.
1929 * som.c (SOM_ALIGN): Define.
1930 (som_begin_writing): If writing an executable, initialize all
1931 fields in the exec header to zero. Update fields in the exec
1932 header as sizes of loadable subspaces are computed. Carefully
1933 preserve alignments when building executables. Actually write the
1934 exec after all the fields are filled in.
1936 * Better long-filename handling. Reads SOM ABI compliant extended
1937 names, but doesn't quite write compliant extended names yet.
1938 * som.c (som_slurp_extended_name_table): Delete function. The
1939 generic code will handle things correctly.
1940 (som_slurp_armap): Seek to the beginning of the next member.
1941 (normalize): New function.
1942 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1943 name table into account when computing the file offsets in the
1944 SOM dictionary. Make sure to align to an even boundary.
1945 (som_write_armap): Initialize the checksum to zero.
1946 (ar_maxchars): Fix. Opps.
1948 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1950 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1951 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

1955 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1956 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1957 * bfd-in2.h: Regenerated.
1959 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1960 this was also named trad_unix_bfd_copy_private_bfd_data.
1962 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1964 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1965 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1966 returns NULL, it is not an error. It's possible that some of
1967 these checks are not necessary (because the size can never be
1968 zero), but putting in the checks is the conservative thing to do
1969 in light of the fact that some of these malloc calls replaced
1970 unchecked alloca calls, in which a zero argument would work fine.
1972 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1974 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1975 duplicate definition.
1976 (osf_core_bfd_is_local_label): Define.
1978 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1979 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1980 failure indication, it merely means there are no relocs.
1982 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1983 after NAME, since SunOS /bin/cc can't handle it.
1985 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1987 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1988 From sukes@glue.umd.edu (Tasuki Hirata).
1990 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1992 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1993 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1994 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1996 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1998 * som.c (som_prep_for_fixups): Detect section symbols based
1999 on either the lack of private data or the symbol flags. Do not
2000 munge section symbol names anymore -- they no longer confuse GDB.
2001 (som_begin_writing): Leave space for an exec header if writing
2003 (som_slurp_symbol_table): Recognize both forms of section symbol
2004 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2005 section symbols to be the name of the section they represent.
2006 Debugging symbols begin with "L$0\001", not just "L$".
2008 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2010 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2012 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2013 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2014 and bfd_is_local_label.
2016 * targets.c: Add new entries to the bfd_target structure.
2018 * bfd.c (bfd_copy_private_bfd_data): New definition.
2020 * section.c (bfd_copy_private_section_data): New definition.
2022 * syms.c (bfd_is_local_label): New definition.

2026 * libbfd.c (bfd_generic_is_local_label): New function.
2028 * *-core.c: Provide default definitions for new functions in
2029 the target vector which all point to bfd_false.
2031 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2032 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2033 Default new vectors for copying private backend data to bfd_true.
2034 Default new vector for determining if a symbol is a local label
2035 to bfd_generic_is_local_label.
2037 * som.c (som_bfd_copy_private_section_data): New function.
2038 (som_bfd_is_local_label): New function.
2039 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2041 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2043 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2045 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2047 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2050 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2051 Indent some of them to GNU standards.
2053 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2054 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2055 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2056 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2057 Update copyright years.
2059 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2061 * som.c (som_prep_for_fixups): A relocation involving the section
2062 symbol for the *ABS* section is really a relocation involving
2064 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2065 undefined symbols. Correctly distinguish between debugger symbols
2066 and section symbols.
2068 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2069 for spaces and subspaces.
2071 * som.c (som_bfd_count_ar_symbols): Fix typo.
2073 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2074 HAS_RELOC based on the object's magic number.
2075 (make_unique_section): Delete function. BFD and its users are
2076 prepared to handle multiple sections with the same name.
2077 (setup_sections): Allocate space on the BFD's obstack to hold
2078 section names. Use bfd_make_setion_anyway rather than the
2079 obsolete make_unique_section.
2080 (som_prep_headers): Choose the correct SOM magic number based
2082 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2084 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

2096 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2097 is always located at the start of the data section to allow
2098 recovery of the dynamic info from a stripped executable.
2099 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2102 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2104 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2105 cruft (like the #pragma alloca for AIX).
2106 In addition to that problem, the C alloca calls xmalloc, which
2107 means checking for being out of memory can't work right. The
2108 following changes remove all uses of alloca from BFD.
2109 * hosts/solaris2.h: Remove alloca cruft.
2110 * som.c: Replace alloca with a fixed size auto array.

2116 * libbfd.h: Rebuilt.
2118 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2120 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2123 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2125 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2126 Elf*_Off typedefs by their expansion, the typedefs have been
2127 removed from include/elf/internal.h.
2128 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2129 SHT_PROGBITS section.
2131 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2133 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2137 * configure.host: Recognize i[34]86-sequent-*.
2139 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2140 return from bfd_seek indicates an error.
2141 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2142 TRAD_CORE_STACK_OFFSET.
2143 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2144 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2146 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2148 * som.[ch]: Do not include libhppa.h in som.c, instead include
2151 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2152 include it in elf32-hppa.h.
2154 * som.c (log2): Return -1 on error rather than aborting.
2155 (setup_sections): Bubble up an error from log2.
2157 * Changes to make HP C compiler happy in both traditional
2159 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2161 (bfd_som_set_section_attributes): Use unsigned int rather than
2162 unsigned char to avoid GNU-C extensions.
2163 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2164 or failure rather than aborting on failure.
2166 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2168 (bfd_som_attach_aux_hdr): Add prototype.
2169 (hppa_som-gen_reloc_type): Likewise.
2171 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2172 (hppa_look_for_stubs_in_section): Do not return false on failure
2173 until rest of code is ready to handle it. Abort for now.
2175 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2177 * bfd-in2.h: Rebuilt.
2179 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
2181 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

2283 COMPLEX relocation support (it's never used anyway).
2284 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

2458 (b_out_relax_section): If a section contains no relocations, don't
2459 bother processing them.
2460 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3163 The sparc (and possibly other?) NLM format requires a different
3164 way to write exports, so add a write_export field to the backend
3165 data (and set it to NULL for everything but the sparc).
