1718 Fill in some fields in the space/subspace headers from the
1720 (som_bfd_copy_private_section_data): Only copy the stuff
1721 that we really need to make objcopy and strip work. Allocate

1748 * som.c (SOM_ALIGN): Define.
1749 (som_begin_writing): If writing an executable, initialize all
1750 fields in the exec header to zero. Update fields in the exec
1751 header as sizes of loadable subspaces are computed. Carefully
1752 preserve alignments when building executables. Actually write the
1753 exec after all the fields are filled in.
1755 * Better long-filename handling. Reads SOM ABI compliant extended
1756 names, but doesn't quite write compliant extended names yet.
1757 * som.c (som_slurp_extended_name_table): Delete function. The
1758 generic code will handle things correctly.
1759 (som_slurp_armap): Seek to the beginning of the next member.
1760 (normalize): New function.
1761 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1762 name table into account when computing the file offsets in the
1763 SOM dictionary. Make sure to align to an even boundary.
1764 (som_write_armap): Initialize the checksum to zero.
1765 (ar_maxchars): Fix. Opps.
1767 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1769 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1770 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1772 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1774 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1775 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1776 * bfd-in2.h: Regenerated.
1778 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1779 this was also named trad_unix_bfd_copy_private_bfd_data.
1781 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1783 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1784 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1785 returns NULL, it is not an error. It's possible that some of
1786 these checks are not necessary (because the size can never be
1787 zero), but putting in the checks is the conservative thing to do
1788 in light of the fact that some of these malloc calls replaced
1789 unchecked alloca calls, in which a zero argument would work fine.
1791 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1793 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1794 duplicate definition.

1797 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1798 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1799 failure indication, it merely means there are no relocs.
1801 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1802 after NAME, since SunOS /bin/cc can't handle it.
1804 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1806 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1807 From sukes@glue.umd.edu (Tasuki Hirata).
1809 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1811 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1812 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1813 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1815 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1817 * som.c (som_prep_for_fixups): Detect section symbols based
1818 on either the lack of private data or the symbol flags. Do not
1819 munge section symbol names anymore -- they no longer confuse GDB.
1820 (som_begin_writing): Leave space for an exec header if writing
1822 (som_slurp_symbol_table): Recognize both forms of section symbol
1823 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1824 section symbols to be the name of the section they represent.
1825 Debugging symbols begin with "L$0\001", not just "L$".
1827 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1829 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1831 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1832 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1833 and bfd_is_local_label.
1835 * targets.c: Add new entries to the bfd_target structure.
1837 * bfd.c (bfd_copy_private_bfd_data): New definition.

1848 the target vector which all point to bfd_false.
1850 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1851 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1852 Default new vectors for copying private backend data to bfd_true.
1853 Default new vector for determining if a symbol is a local label
1854 to bfd_generic_is_local_label.
1856 * som.c (som_bfd_copy_private_section_data): New function.
1857 (som_bfd_is_local_label): New function.
1858 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1860 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1862 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1864 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1866 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1869 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1870 Indent some of them to GNU standards.
1872 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1873 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1874 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1875 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1876 Update copyright years.
1878 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1880 * som.c (som_prep_for_fixups): A relocation involving the section
1881 symbol for the *ABS* section is really a relocation involving
1883 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1884 undefined symbols. Correctly distinguish between debugger symbols
1885 and section symbols.
1887 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1888 for spaces and subspaces.
1890 * som.c (som_bfd_count_ar_symbols): Fix typo.
1892 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1893 HAS_RELOC based on the object's magic number.
1894 (make_unique_section): Delete function. BFD and its users are
1895 prepared to handle multiple sections with the same name.
1896 (setup_sections): Allocate space on the BFD's obstack to hold
1897 section names. Use bfd_make_setion_anyway rather than the
1898 obsolete make_unique_section.
1899 (som_prep_headers): Choose the correct SOM magic number based
1901 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

1921 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1923 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1924 cruft (like the #pragma alloca for AIX).
1925 In addition to that problem, the C alloca calls xmalloc, which
1926 means checking for being out of memory can't work right. The
1927 following changes remove all uses of alloca from BFD.
1928 * hosts/solaris2.h: Remove alloca cruft.
1929 * som.c: Replace alloca with a fixed size auto array.

1942 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1944 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1945 Elf*_Off typedefs by their expansion, the typedefs have been
1946 removed from include/elf/internal.h.
1947 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1948 SHT_PROGBITS section.
1950 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1961 TRAD_CORE_STACK_OFFSET.
1962 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1963 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1965 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1967 * som.[ch]: Do not include libhppa.h in som.c, instead include
1970 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1971 include it in elf32-hppa.h.
1973 * som.c (log2): Return -1 on error rather than aborting.
1974 (setup_sections): Bubble up an error from log2.
1976 * Changes to make HP C compiler happy in both traditional
1978 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1980 (bfd_som_set_section_attributes): Use unsigned int rather than
1981 unsigned char to avoid GNU-C extensions.
1982 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1983 or failure rather than aborting on failure.
1985 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1987 (bfd_som_attach_aux_hdr): Add prototype.
1988 (hppa_som-gen_reloc_type): Likewise.

2026 Set reloc->sym_ptr_ptr appropriately.
2027 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2028 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2029 argument. Use the output symbols when canonicalizing the relocs,
2030 creating them if necessary.
2032 * linker.c (_bfd_generic_link_output_symbols): Do not
2033 rebuild/clobber the output symbols if they already exist.

2050 error code propogation working. Work on spacing and indention.
2051 Add FIXMEs for unresolved problems. Use enums rather than
2052 #defines for lots of things. Merge two functions which build
2053 linker stubs into a single function (so they can easily share a
2054 ton of common code).
2056 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2058 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2059 avoid depending upon right shifts of signed numbers, and to
2060 correct handling of src_mask with lower bits zero.

2092 (elf_hppa_final_processing): Add extern decl.
2094 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
2095 comments. PARAMize some static functions. Delete unused functions.

2098 in many places. Use default case when possible instead of listing
2099 each case separately. Abort for bad errors until we get error
2100 code propogation working. Work on spacing and indention problems.
2101 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2102 COMPLEX relocation support (it's never used anyway).
2103 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2104 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
2105 (elf_hppa_tc_make_sections): Likewise.

2146 * elfcode.h (alloca): Delete declaration.
2148 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
2149 number rather than HP9000S800_ID. Note som.c is careful
2150 to make sure CPU_PA_RISC1_0 is always defined.
2152 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
2154 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

2173 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
2174 and bss_size bfd_size_type instead of unsigned long. Make
2175 text_start and data_start bfd_vma instead of unsigned long.

2278 bother processing them.

2844 bfd_som_set_subsection_attributes): Change parameters from char
2845 to int. Following a prototype with an old-style function definition

2952 use get_value to get the symbol value and check for undefined
2954 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
2955 undefined, look it up in the linker hash table.
2957 * aoutx.h (translate_symbol_table): The string index 0 has a

2982 The sparc (and possibly other?) NLM format requires a different
2983 way to write exports, so add a write_export field to the backend
2984 data (and set it to NULL for everything but the sparc).
