1723 Fill in some fields in the space/subspace headers from the
1725 (som_bfd_copy_private_section_data): Only copy the stuff
1726 that we really need to make objcopy and strip work. Allocate

1743 (som_prep_headers): Allocate space for and attach a file header
1744 to the output bfd. For executables, use the saved system_id
1745 value rather than trying to guess the right value. Do not abort
1746 wwhen setting file_hdr->entry* for executables.
1747 (som_begin_writing): For executables, set the exec_entry and
1749 (som_copy_private_backend_section_data): Always return a value.
1751 * libhppa.h (PA_PAGESIZE): Define.
1753 * som.c (SOM_ALIGN): Define.
1754 (som_begin_writing): If writing an executable, initialize all
1755 fields in the exec header to zero. Update fields in the exec
1756 header as sizes of loadable subspaces are computed. Carefully
1757 preserve alignments when building executables. Actually write the
1758 exec after all the fields are filled in.
1760 * Better long-filename handling. Reads SOM ABI compliant extended
1761 names, but doesn't quite write compliant extended names yet.
1762 * som.c (som_slurp_extended_name_table): Delete function. The
1763 generic code will handle things correctly.
1764 (som_slurp_armap): Seek to the beginning of the next member.
1765 (normalize): New function.
1766 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1767 name table into account when computing the file offsets in the
1768 SOM dictionary. Make sure to align to an even boundary.
1769 (som_write_armap): Initialize the checksum to zero.
1770 (ar_maxchars): Fix. Opps.
1772 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1774 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1775 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1777 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1779 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1780 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1781 * bfd-in2.h: Regenerated.
1783 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1784 this was also named trad_unix_bfd_copy_private_bfd_data.
1786 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1788 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1789 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1790 returns NULL, it is not an error. It's possible that some of
1791 these checks are not necessary (because the size can never be
1792 zero), but putting in the checks is the conservative thing to do
1793 in light of the fact that some of these malloc calls replaced
1794 unchecked alloca calls, in which a zero argument would work fine.
1796 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1798 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1799 duplicate definition.
1800 (osf_core_bfd_is_local_label): Define.
1802 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1803 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1804 failure indication, it merely means there are no relocs.
1806 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1807 after NAME, since SunOS /bin/cc can't handle it.
1809 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1811 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1812 From sukes@glue.umd.edu (Tasuki Hirata).
1814 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1816 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1817 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1818 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1820 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1822 * som.c (som_prep_for_fixups): Detect section symbols based
1823 on either the lack of private data or the symbol flags. Do not
1824 munge section symbol names anymore -- they no longer confuse GDB.
1825 (som_begin_writing): Leave space for an exec header if writing
1827 (som_slurp_symbol_table): Recognize both forms of section symbol
1828 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1829 section symbols to be the name of the section they represent.
1830 Debugging symbols begin with "L$0\001", not just "L$".
1832 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1834 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1836 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1837 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1838 and bfd_is_local_label.
1840 * targets.c: Add new entries to the bfd_target structure.
1842 * bfd.c (bfd_copy_private_bfd_data): New definition.

1853 the target vector which all point to bfd_false.
1855 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1856 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1857 Default new vectors for copying private backend data to bfd_true.
1858 Default new vector for determining if a symbol is a local label
1859 to bfd_generic_is_local_label.
1861 * som.c (som_bfd_copy_private_section_data): New function.
1862 (som_bfd_is_local_label): New function.
1863 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1865 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1867 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1869 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1871 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1874 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1875 Indent some of them to GNU standards.
1877 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1878 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1879 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1880 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1881 Update copyright years.
1883 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1885 * som.c (som_prep_for_fixups): A relocation involving the section
1886 symbol for the *ABS* section is really a relocation involving
1888 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1889 undefined symbols. Correctly distinguish between debugger symbols
1890 and section symbols.
1892 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1893 for spaces and subspaces.
1895 * som.c (som_bfd_count_ar_symbols): Fix typo.
1897 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1898 HAS_RELOC based on the object's magic number.
1899 (make_unique_section): Delete function. BFD and its users are
1900 prepared to handle multiple sections with the same name.
1901 (setup_sections): Allocate space on the BFD's obstack to hold
1902 section names. Use bfd_make_setion_anyway rather than the
1903 obsolete make_unique_section.
1904 (som_prep_headers): Choose the correct SOM magic number based
1906 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

1926 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1928 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1929 cruft (like the #pragma alloca for AIX).
1930 In addition to that problem, the C alloca calls xmalloc, which
1931 means checking for being out of memory can't work right. The
1932 following changes remove all uses of alloca from BFD.
1933 * hosts/solaris2.h: Remove alloca cruft.
1934 * som.c: Replace alloca with a fixed size auto array.

1939 * linker.c: Replace alloca with obstack_alloc.
1940 * libbfd.h: Rebuilt.
1942 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)

1947 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1949 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1950 Elf*_Off typedefs by their expansion, the typedefs have been
1951 removed from include/elf/internal.h.
1952 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1953 SHT_PROGBITS section.
1955 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1957 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1963 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1964 return from bfd_seek indicates an error.
1965 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1966 TRAD_CORE_STACK_OFFSET.
1967 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1968 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1970 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1972 * som.[ch]: Do not include libhppa.h in som.c, instead include
1975 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1976 include it in elf32-hppa.h.
1978 * som.c (log2): Return -1 on error rather than aborting.
1979 (setup_sections): Bubble up an error from log2.
1981 * Changes to make HP C compiler happy in both traditional
1983 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1985 (bfd_som_set_section_attributes): Use unsigned int rather than
1986 unsigned char to avoid GNU-C extensions.
1987 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1988 or failure rather than aborting on failure.
1990 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1992 (bfd_som_attach_aux_hdr): Add prototype.
1993 (hppa_som-gen_reloc_type): Likewise.

2032 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2033 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2034 argument. Use the output symbols when canonicalizing the relocs,
2035 creating them if necessary.
2037 * linker.c (_bfd_generic_link_output_symbols): Do not
2038 rebuild/clobber the output symbols if they already exist.

2055 error code propogation working. Work on spacing and indention.
2056 Add FIXMEs for unresolved problems. Use enums rather than
2057 #defines for lots of things. Merge two functions which build
2058 linker stubs into a single function (so they can easily share a
2059 ton of common code).
2061 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2063 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2064 avoid depending upon right shifts of signed numbers, and to
2065 correct handling of src_mask with lower bits zero.

2097 (elf_hppa_final_processing): Add extern decl.
2099 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
2100 comments. PARAMize some static functions. Delete unused functions.

2104 each case separately. Abort for bad errors until we get error
2105 code propogation working. Work on spacing and indention problems.

2107 COMPLEX relocation support (it's never used anyway).
2108 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2109 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).

2151 * elfcode.h (alloca): Delete declaration.
2153 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
2154 number rather than HP9000S800_ID. Note som.c is careful
2155 to make sure CPU_PA_RISC1_0 is always defined.
2157 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
2159 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

2178 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
2179 and bss_size bfd_size_type instead of unsigned long. Make
2180 text_start and data_start bfd_vma instead of unsigned long.

2697 * srec.c (srec_write_record): Put CONST keyword for "src" before
2698 "unsigned", some compilers don't like it after "unsigned".
2699 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

2849 bfd_som_set_subsection_attributes): Change parameters from char
2850 to int. Following a prototype with an old-style function definition

2957 use get_value to get the symbol value and check for undefined
2959 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
2960 undefined, look it up in the linker hash table.
2962 * aoutx.h (translate_symbol_table): The string index 0 has a

2987 The sparc (and possibly other?) NLM format requires a different
2988 way to write exports, so add a write_export field to the backend
2989 data (and set it to NULL for everything but the sparc).

3039 read_dynamic_relocs fields.
3040 * aout-target.h (MY(backend_data)): Initialize
