1734 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1736 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1738 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1740 * som.c (bfd_section_from_som_symbol): Only to do the value
1741 comparison for function symbols within executables.
1743 * som.c (bfd_section_from_som_symbol): Renamed from
1744 som_section_from_subspace_index. Pass in a native SOM symbol.
1745 For executables, iterate through the sections to find out
1746 which contains the symbol's address rather than using the
1747 symbol_info field. (symbol_info has a different meaning for
1748 dynamicly linked executables.)
1750 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1753 * som.c (som_begin_writing): Fix braino (one call to align
1754 space/subspace data was done unconditionally rather than
1755 just for executables.)
1757 * som.c (som_begin_writing): Align text in all executables to
1758 make HPUX kernel happy. Fixes strip/objcopy for shared
1761 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1763 * som.c (som_begin_writing): Account for alignment needs of
1764 subspaces too when writing executables. Never request a negative
1765 bss size. Fixes some problems with demand paged executables,
1766 still having problems with pure executables and shared executables.
1768 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1770 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1771 bfd_zalloc for rawptr, because later on we may call free, not
1774 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1775 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1776 * cisco-core.c: New file.
1777 * Makefile.in: Change accordingly.
1778 * configure.in: Recognize cisco_core_vec.
1779 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1780 * targets.c: Add cisco_core_vec.
1781 * bfd-in2.h: Rebuilt.
1783 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1785 * som.h (som_copyable_section_data_struct): New structure
1786 containing all the private section information which needs
1787 to be copied from input section to output section during
1789 (som_section_data_struct): Remove several fields now in
1790 som_copyable_section_data_struct. Make the space and
1791 subspace dictionaries be pointers (to save space when
1792 only reading objects).
1794 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1795 some references changed. Allocate a copyable data stucture if
1796 none exists. Store info into the copyable data structure.
1797 (bfd_som_set_subsection_attributes): Likewise.
1798 (som_is_space, som_is_subspace, som_is_container): New functions.
1799 Use these instead of directly accessing private data.
1800 (som_prep_headers): Allocate space and subspace headers here.
1801 Fill in some fields in the space/subspace headers from the
1803 (som_bfd_copy_private_section_data): Only copy the stuff
1804 that we really need to make objcopy and strip work. Allocate
1805 the copy_data structure for the output bfd before copying.
1807 * som.h (struct som_exec_data): New structure to hold exec
1808 info that must be preserved when running objcopy/strip.
1809 (struct somdata): Add new "exec_data" field and accessor
1810 macro. Add some comments on how the various fields are used.
1811 (som_section_data_struct): Make is_space and is_subspace bitfields.
1812 Delete unused subspace_index. All references now use the
1813 target_index field within the section structure itself.
1815 * som.c (make_unique_section): Delete unused declaration.
1816 (som_bfd_copy_private_bfd_data): New function.
1817 (som_object_setup): Allocate space for and save exec information
1818 that needs to be copied during objcopy/strip.
1819 (som_mkobject): Do not allocate space for a file header here.
1820 It is not used when only reading SOM objects.
1821 (som_prep_headers): Allocate space for and attach a file header
1822 to the output bfd. For executables, use the saved system_id
1823 value rather than trying to guess the right value. Do not abort
1824 wwhen setting file_hdr->entry* for executables.
1825 (som_begin_writing): For executables, set the exec_entry and
1827 (som_copy_private_backend_section_data): Always return a value.
1829 * libhppa.h (PA_PAGESIZE): Define.
1831 * som.c (SOM_ALIGN): Define.
1832 (som_begin_writing): If writing an executable, initialize all
1833 fields in the exec header to zero. Update fields in the exec
1834 header as sizes of loadable subspaces are computed. Carefully
1835 preserve alignments when building executables. Actually write the
1836 exec after all the fields are filled in.
1838 * Better long-filename handling. Reads SOM ABI compliant extended
1839 names, but doesn't quite write compliant extended names yet.
1840 * som.c (som_slurp_extended_name_table): Delete function. The
1841 generic code will handle things correctly.
1842 (som_slurp_armap): Seek to the beginning of the next member.
1843 (normalize): New function.
1844 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1845 name table into account when computing the file offsets in the
1846 SOM dictionary. Make sure to align to an even boundary.
1847 (som_write_armap): Initialize the checksum to zero.
1848 (ar_maxchars): Fix. Opps.
1850 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1852 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1853 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1855 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1857 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1858 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1859 * bfd-in2.h: Regenerated.
1861 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1862 this was also named trad_unix_bfd_copy_private_bfd_data.
1864 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1866 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1867 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1868 returns NULL, it is not an error. It's possible that some of
1869 these checks are not necessary (because the size can never be
1870 zero), but putting in the checks is the conservative thing to do
1871 in light of the fact that some of these malloc calls replaced
1872 unchecked alloca calls, in which a zero argument would work fine.
1874 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1876 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1877 duplicate definition.
1878 (osf_core_bfd_is_local_label): Define.
1880 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1881 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1882 failure indication, it merely means there are no relocs.
1884 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1885 after NAME, since SunOS /bin/cc can't handle it.
1887 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1889 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1890 From sukes@glue.umd.edu (Tasuki Hirata).
1892 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1894 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1895 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1896 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1898 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1900 * som.c (som_prep_for_fixups): Detect section symbols based
1901 on either the lack of private data or the symbol flags. Do not
1902 munge section symbol names anymore -- they no longer confuse GDB.
1903 (som_begin_writing): Leave space for an exec header if writing
1905 (som_slurp_symbol_table): Recognize both forms of section symbol
1906 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1907 section symbols to be the name of the section they represent.
1908 Debugging symbols begin with "L$0\001", not just "L$".
1910 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1912 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1914 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1915 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1916 and bfd_is_local_label.
1918 * targets.c: Add new entries to the bfd_target structure.
1920 * bfd.c (bfd_copy_private_bfd_data): New definition.
1922 * section.c (bfd_copy_private_section_data): New definition.
1924 * syms.c (bfd_is_local_label): New definition.
1926 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1928 * libbfd.c (bfd_generic_is_local_label): New function.
1930 * *-core.c: Provide default definitions for new functions in
1931 the target vector which all point to bfd_false.
1933 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1934 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1935 Default new vectors for copying private backend data to bfd_true.
1936 Default new vector for determining if a symbol is a local label
1937 to bfd_generic_is_local_label.
1939 * som.c (som_bfd_copy_private_section_data): New function.
1940 (som_bfd_is_local_label): New function.
1941 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1943 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1945 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1947 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1949 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1952 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1953 Indent some of them to GNU standards.
1955 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1956 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1957 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1958 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1959 Update copyright years.
1961 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1963 * som.c (som_prep_for_fixups): A relocation involving the section
1964 symbol for the *ABS* section is really a relocation involving
1966 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1967 undefined symbols. Correctly distinguish between debugger symbols
1968 and section symbols.
1970 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1971 for spaces and subspaces.
1973 * som.c (som_bfd_count_ar_symbols): Fix typo.
1975 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1976 HAS_RELOC based on the object's magic number.
1977 (make_unique_section): Delete function. BFD and its users are
1978 prepared to handle multiple sections with the same name.
1979 (setup_sections): Allocate space on the BFD's obstack to hold
1980 section names. Use bfd_make_setion_anyway rather than the
1981 obsolete make_unique_section.
1982 (som_prep_headers): Choose the correct SOM magic number based
1984 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1986 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1988 * elf32-ppc.c: Renamed from elf32-powerpc.c.
1989 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
1990 * Makefile.in, configure.in: Corresponding changes.
1992 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1994 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
1996 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1998 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1999 is always located at the start of the data section to allow
2000 recovery of the dynamic info from a stripped executable.
2001 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2004 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2006 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2007 cruft (like the #pragma alloca for AIX).
2008 In addition to that problem, the C alloca calls xmalloc, which
2009 means checking for being out of memory can't work right. The
2010 following changes remove all uses of alloca from BFD.
2011 * hosts/solaris2.h: Remove alloca cruft.
2012 * som.c: Replace alloca with a fixed size auto array.
2013 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2014 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2015 sunos.c: Replace alloca with malloc and appropriate error checking and
2017 * linker.c: Replace alloca with obstack_alloc.
2018 * libbfd.h: Rebuilt.
2020 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2022 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2025 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2027 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2028 Elf*_Off typedefs by their expansion, the typedefs have been
2029 removed from include/elf/internal.h.
2030 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2031 SHT_PROGBITS section.
2033 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2035 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2039 * configure.host: Recognize i[34]86-sequent-*.
2041 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2042 return from bfd_seek indicates an error.
2043 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2044 TRAD_CORE_STACK_OFFSET.
2045 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2046 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2048 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2050 * som.[ch]: Do not include libhppa.h in som.c, instead include
2053 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2054 include it in elf32-hppa.h.
2056 * som.c (log2): Return -1 on error rather than aborting.
2057 (setup_sections): Bubble up an error from log2.
2059 * Changes to make HP C compiler happy in both traditional
2061 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2063 (bfd_som_set_section_attributes): Use unsigned int rather than
2064 unsigned char to avoid GNU-C extensions.
2065 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2066 or failure rather than aborting on failure.
2068 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2070 (bfd_som_attach_aux_hdr): Add prototype.
2071 (hppa_som-gen_reloc_type): Likewise.
2073 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2074 (hppa_look_for_stubs_in_section): Do not return false on failure
2075 until rest of code is ready to handle it. Abort for now.

2079 * bfd-in2.h: Rebuilt.
2081 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
2083 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

2087 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
2089 * config.bfd : Add i386-os9k.
2090 * config/i386-os9k.mt : Newly add os9k target makefile.
2092 * i386os9k.c : new file to handle os9k format bfd.
2093 * Makefile.in : Handle new file i386os9k.c
2094 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2095 * cache.c : Initialize cache_sentinel to 0.

2099 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2100 action in case where caller specified no argument relocation.
2101 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2102 right in the original relocation and the stub's relocation.
2104 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2105 unused symbols argument.
2107 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2108 than asymbol * for original target symbol. All callers changed.
2109 Set reloc->sym_ptr_ptr appropriately.
2110 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2111 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2112 argument. Use the output symbols when canonicalizing the relocs,
2113 creating them if necessary.
2115 * linker.c (_bfd_generic_link_output_symbols): Do not
2116 rebuild/clobber the output symbols if they already exist.
2118 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2120 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2121 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2122 * bfd-in2.h: Rebuilt.
2124 * srec.c (hex_value): Always set to a size of 256 bytes.
2125 (srec_init): Cosmetic changes.
2127 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2129 * elf32-hppa.c: Second half of major cleanup. More comments,
2130 PARAMize and staticize rest of functions. Delete unused
2131 functions. Delete unused/unnecessary arguments to some functions.
2132 Group static vars together. Abort for bad errors until we have
2133 error code propogation working. Work on spacing and indention.
2134 Add FIXMEs for unresolved problems. Use enums rather than
2135 #defines for lots of things. Merge two functions which build
2136 linker stubs into a single function (so they can easily share a
2137 ton of common code).
2139 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2141 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2142 avoid depending upon right shifts of signed numbers, and to
2143 correct handling of src_mask with lower bits zero.
2145 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2146 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

2153 (write_shdrs_and_ehdr): Make count unsigned.
2154 (assign_file_positions_for_relocs): Make i unsigned.
2155 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
2156 (section_from_elf_index): Make index argument unsigned.
2158 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
2160 * elfcode.h: Don't include assert.h.
2161 (swap_out_syms): Use BFD_ASSERT rather than assert.

2166 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
2169 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2171 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
2173 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
2174 (elf_hppa_tc_make_sections): Likewise.
2175 (elf_hppa_final_processing): Add extern decl.
2177 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
2178 comments. PARAMize some static functions. Delete unused functions.
2179 Delete unused/unnecessary arguments to many functions. Group
2180 static vars together. Collapse common case statements together
2181 in many places. Use default case when possible instead of listing
2182 each case separately. Abort for bad errors until we get error
2183 code propogation working. Work on spacing and indention problems.
2184 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2185 COMPLEX relocation support (it's never used anyway).
2186 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2187 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
2188 (elf_hppa_tc_make_sections): Likewise.

3032 (get_value): If the symbol is undefined, look it up in the linker
3034 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
3035 use get_value to get the symbol value and check for undefined
3037 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3038 undefined, look it up in the linker hash table.
3040 * aoutx.h (translate_symbol_table): The string index 0 has a

3065 The sparc (and possibly other?) NLM format requires a different
3066 way to write exports, so add a write_export field to the backend
3067 data (and set it to NULL for everything but the sparc).
