1597 for Dynix. Remove inclusion of dynix3.h, Dynix bfd is now handled by
1598 i386dynix.c
1599
1600 Mon Mar 28 12:53:27 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

1614
1615 * som.c (som_begin_writing): New approach at dealing with holes
1616 in executables left by the HP linker. Does not rely on subspace
1617 alignments as subspaces are *NOT* guaranteed to be properly
1618 aligned in an executable (can you believe that!).
1619
1620 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1621
1622 * som.c (som_get_section_contents): New function. Do not try

1627 read. (bfd_error_system_call or bfd_error_file_truncated).
1628
1629 * som.c: Do not blindly set bfd_error_system_call after a
1630 failing bfd_read, bfd_write, or bfd_seek. In a few places

1669 from undefined to section. Change handling of PC relative relocs:
1670 if against a section, they are correct in the object file, if
1671 against an external symbol they are pcrel_offset.

1765 relocs when allocating space for relocations. Set SEC_RELOC flag
1766 for any section which has relocs. Handle link_order relocs in
1767 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1768 add_symbls entry point.
1769
1770 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before

1799 extended name table.
1800
1801 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1802

1806 from call to _bfd_generic_link_add_one_symbol.
1807 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

1809 instead of bitsize to add_to_set call back.
1810 (_bfd_generic_final_link): Account for link_order relocs when
1811 allocating space for relocations. Handle them in link_order loop.
1812 (_bfd_generic_reloc_link_order): New function.

1825 input BFDs.
1826 (aout_link_reloc_link_order): New function.

1845
1846 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1847
1848 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1849
1850 * som.c (bfd_section_from_som_symbol): Only to do the value
1851 comparison for function symbols within executables.
1852
1853 * som.c (bfd_section_from_som_symbol): Renamed from
1854 som_section_from_subspace_index. Pass in a native SOM symbol.
1855 For executables, iterate through the sections to find out
1856 which contains the symbol's address rather than using the
1857 symbol_info field. (symbol_info has a different meaning for
1858 dynamicly linked executables.)
1859
1860 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1861 bfd_zmalloc.
1862
1863 * som.c (som_begin_writing): Fix braino (one call to align
1864 space/subspace data was done unconditionally rather than
1865 just for executables.)
1866
1867 * som.c (som_begin_writing): Align text in all executables to
1868 make HPUX kernel happy. Fixes strip/objcopy for shared
1869 executables.
1870
1871 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1872
1873 * som.c (som_begin_writing): Account for alignment needs of
1874 subspaces too when writing executables. Never request a negative
1875 bss size. Fixes some problems with demand paged executables,
1876 still having problems with pure executables and shared executables.
1877
1878 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1879
1880 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1881 bfd_zalloc for rawptr, because later on we may call free, not
1882 bfd_release, on it.
1883
1884 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1885 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1886 * cisco-core.c: New file.
1887 * Makefile.in: Change accordingly.
1888 * configure.in: Recognize cisco_core_vec.

1890 * targets.c: Add cisco_core_vec.
1891 * bfd-in2.h: Rebuilt.
1892
1893 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1894
1895 * som.h (som_copyable_section_data_struct): New structure
1896 containing all the private section information which needs
1897 to be copied from input section to output section during
1898 objcopy or strip.
1899 (som_section_data_struct): Remove several fields now in
1900 som_copyable_section_data_struct. Make the space and
1901 subspace dictionaries be pointers (to save space when
1902 only reading objects).
1903
1904 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1905 some references changed. Allocate a copyable data stucture if
1906 none exists. Store info into the copyable data structure.
1907 (bfd_som_set_subsection_attributes): Likewise.
1908 (som_is_space, som_is_subspace, som_is_container): New functions.
1909 Use these instead of directly accessing private data.
1910 (som_prep_headers): Allocate space and subspace headers here.
1911 Fill in some fields in the space/subspace headers from the
1912 copyable data.
1913 (som_bfd_copy_private_section_data): Only copy the stuff
1914 that we really need to make objcopy and strip work. Allocate
1915 the copy_data structure for the output bfd before copying.
1916
1917 * som.h (struct som_exec_data): New structure to hold exec
1918 info that must be preserved when running objcopy/strip.
1919 (struct somdata): Add new "exec_data" field and accessor
1920 macro. Add some comments on how the various fields are used.
1921 (som_section_data_struct): Make is_space and is_subspace bitfields.
1922 Delete unused subspace_index. All references now use the
1923 target_index field within the section structure itself.
1924
1925 * som.c (make_unique_section): Delete unused declaration.
1926 (som_bfd_copy_private_bfd_data): New function.
1927 (som_object_setup): Allocate space for and save exec information
1928 that needs to be copied during objcopy/strip.
1929 (som_mkobject): Do not allocate space for a file header here.
1930 It is not used when only reading SOM objects.
1931 (som_prep_headers): Allocate space for and attach a file header
1932 to the output bfd. For executables, use the saved system_id
1933 value rather than trying to guess the right value. Do not abort
1934 wwhen setting file_hdr->entry* for executables.
1935 (som_begin_writing): For executables, set the exec_entry and
1936 exec_flags fields.
1937 (som_copy_private_backend_section_data): Always return a value.
1938
1939 * libhppa.h (PA_PAGESIZE): Define.
1940
1941 * som.c (SOM_ALIGN): Define.
1942 (som_begin_writing): If writing an executable, initialize all
1943 fields in the exec header to zero. Update fields in the exec
1944 header as sizes of loadable subspaces are computed. Carefully
1945 preserve alignments when building executables. Actually write the
1946 exec after all the fields are filled in.
1947
1948 * Better long-filename handling. Reads SOM ABI compliant extended
1949 names, but doesn't quite write compliant extended names yet.
1950 * som.c (som_slurp_extended_name_table): Delete function. The
1951 generic code will handle things correctly.
1952 (som_slurp_armap): Seek to the beginning of the next member.
1953 (normalize): New function.
1954 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1955 name table into account when computing the file offsets in the
1956 SOM dictionary. Make sure to align to an even boundary.
1957 (som_write_armap): Initialize the checksum to zero.
1958 (ar_maxchars): Fix. Opps.
1959
1960 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1961
1962 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1963 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1964
1965 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1966
1967 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1968 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1969 * bfd-in2.h: Regenerated.
1970
1971 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1972 this was also named trad_unix_bfd_copy_private_bfd_data.
1973
1974 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1975
1976 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1977 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1978 returns NULL, it is not an error. It's possible that some of
1979 these checks are not necessary (because the size can never be
1980 zero), but putting in the checks is the conservative thing to do
1981 in light of the fact that some of these malloc calls replaced
1982 unchecked alloca calls, in which a zero argument would work fine.
1983
1984 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1985
1986 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1987 duplicate definition.
1988 (osf_core_bfd_is_local_label): Define.
1989
1990 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1991 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1992 failure indication, it merely means there are no relocs.
1993
1994 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1995 after NAME, since SunOS /bin/cc can't handle it.
1996

2004 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2005 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2006 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

2009
2010 * som.c (som_prep_for_fixups): Detect section symbols based
2011 on either the lack of private data or the symbol flags. Do not
2012 munge section symbol names anymore -- they no longer confuse GDB.

2014 an executable.
2015 (som_slurp_symbol_table): Recognize both forms of section symbol
2016 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2017 section symbols to be the name of the section they represent.
2018 Debugging symbols begin with "L$0\001", not just "L$".
2019

2070
2071 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2072
2073 * som.c (som_prep_for_fixups): A relocation involving the section
2074 symbol for the *ABS* section is really a relocation involving
2075 no symbol.

2077 undefined symbols. Correctly distinguish between debugger symbols
2078 and section symbols.

2088 prepared to handle multiple sections with the same name.
2089 (setup_sections): Allocate space on the BFD's obstack to hold
2090 section names. Use bfd_make_setion_anyway rather than the

2115
2116 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2117 cruft (like the #pragma alloca for AIX).
2118 In addition to that problem, the C alloca calls xmalloc, which
2119 means checking for being out of memory can't work right. The
2120 following changes remove all uses of alloca from BFD.
2121 * hosts/solaris2.h: Remove alloca cruft.
2122 * som.c: Replace alloca with a fixed size auto array.

2215 unused symbols argument.
2216
2217 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

2220 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2221 (hppa_elf_look_for_stubs_in_section): No longer need symbols

2243 error code propogation working. Work on spacing and indention.
2244 Add FIXMEs for unresolved problems. Use enums rather than
2245 #defines for lots of things. Merge two functions which build
2246 linker stubs into a single function (so they can easily share a
2247 ton of common code).

2292 each case separately. Abort for bad errors until we get error
2293 code propogation working. Work on spacing and indention problems.
2294 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2295 COMPLEX relocation support (it's never used anyway).

2340
2341 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

2884
2885 * srec.c (srec_write_record): Put CONST keyword for "src" before
2886 "unsigned", some compilers don't like it after "unsigned".
2887 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

2917 entry has type STY_LD change the x_scnlen into a pointer to a
2918 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
2919 value into a pointer to a symbol and set fix_value.
2920 * libcoff.h: Rebuilt.

2932 .debug section.
2933 (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen

2994 accordingly.
2995 * libcoff.h: Rebuilt.
2996 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new
2997 arguments. If RS6000COFF_C, only treat C_EXT and C_HIDEXT

3003
3004 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
3005 (only testing for m68k and vax at the moment); do verify that the
3006 preprocessor didn't trash the arch name inside the string version.
3007 Don't print out "pagesize =" line that prevents output from
3008 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
3009 results.

3020
3021 * hosts/vaxbsd.h (HOST_STACK_END_ADDR): Vax BSD doesn't define

3035
3036 * som.c, som.h (bfd_som_set_section_attributes,
3037 bfd_som_set_subsection_attributes): Change parameters from char

3049
3050 * archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
3051 try to overlay the internal carsyms on the external symdefs. That
3052 can not work if the size of a host pointer is larger than 4 bytes.

3126 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).
3127

3148 undefined, look it up in the linker hash table.
3149
3150 * aoutx.h (translate_symbol_table): The string index 0 has a
3151 special meaning for normal symbols, but not for dynamic symbols.

3175 The sparc (and possibly other?) NLM format requires a different
3176 way to write exports, so add a write_export field to the backend
3177 data (and set it to NULL for everything but the sparc).
3178
3179 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3180
3181 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,

3419 * configure.in (nlm32_alpha_vec): Set target64 to true.
3420
3421 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
