Changes in 2.28:
* This version of binutils fixes a problem with PowerPC VLE 16A and 16D
relocations which were functionally swapped, for example,
R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D
performed like R_PPC_VLE_HA16A. This could have been fixed by
renumbering relocations, which would keep object files created by an
older version of gas compatible with a newer ld. However, that would
require an ABI update, affecting other assemblers and linkers that
create and process the relocations correctly. It is recommended that
all VLE object files be recompiled, but ld can modify the relocations
if --vle-reloc-fixup is passed to ld. If the new ld command line
option is not used, ld will ld warn on finding relocations inconsistent
with the instructions being relocated.
* The nm program has a new command line option (--with-version-strings)
which will display a symbol's version information, if any, after the
symbol's name.
* The ARC port of objdump now accepts a -M option to specify the extra
instruction class(es) that should be disassembled.
* The --remove-section option for objcopy and strip now accepts section
patterns starting with an exclamation point to indicate a non-matching
section. A non-matching section is removed from the set of sections
matched by an earlier --remove-section pattern.
* The --only-section option for objcopy now accepts section patterns
starting with an exclamation point to indicate a non-matching section.
A non-matching section is removed from the set of sections matched by
an earlier --only-section pattern.
objcopy/strip: Add option --remove-relocations=SECTIONPATTERN The objcopy and strip tools make use of the bfd library to manipulate the state of the input file (to produce an output file). Within the input file (for ELF at least), relocations are held within a section, and so, if the user wanted to remove the relocations, but keep the section to which the relocations would have been applied, it is tempting to think that specifying the name of a relocation section to objcopy's --remove-section option might do what you want, for example: objcopy --remove-section=.rela.text input.elf output.elf However, this does not work. The reason is that when the input file is loaded, relocations are not managed as sections, but are, instead, loaded as data associated with the section to which the relocations would be applied. In our example above the relocations in '.rela.text' are held as data on the section '.text' once 'input.elf' is loaded. One task that objcopy and strip do is copy the relocations from the input file to the output file if the section is also being copied from the input file to the output file. This commit adds a new command line option for objcopy and strip, --remove-relocations, which can be used to remove the relocations, while keeping the section that the relocations would have been applied to, for example: objcopy --remove-relocations=.text input.elf output.elf in this case the section '.text' will appear in both 'input.elf' and 'output.elf', but any relocations in 'input.elf' that apply to '.text' will not be present in 'output.elf'. I have also added a special case to the handling of --remove-section that spots if a user tries to remove a relocation section (currently this is done by spotting the '.rela.' or '.rel.' prefix) and forwards the request to --remove-relocations. As with --remove-section and --only-section the --remove-relocations option supports the '!' prefix on the section-patterns it takes to allow for sections to be specifically not matched. There are tests for all the new functionality. binutils/ChangeLog: * doc/binutils.texi (objcopy): Document 'remove-relocations'. (strip): Likewise. * objcopy.c (SECTION_CONTEXT_REMOVE_RELOCS): Define. (enum command_line_switch): Add 'OPTION_REMOVE_RELOCS'. (struct option strip_options): Add 'remove-relocations'.

2015-08-22 03:08:26 +08:00
* New --remove-relocations=SECTIONPATTERN option for objcopy and strip.
This option can be used to remove sections containing relocations.
The SECTIONPATTERN is the section to which the relocations apply, not
the relocation section itself.
Changes in 2.27:
Enable 64-bit archives in ar and ranlib Since existing ld and gold support the 64-bit (MIPS) ELF archives, we can use the 64-bit (MIPS) ELF archives as 64-bit archives. Since the plugin target is used to create archive in plugin-enabled ar, we need a way to enable 64-bit archives in the plugin target. This patch adds --enable-64-bit-archive to bfd to force 64-bit archives in ar and ranlib. Since both 64-bit MIPS and s390 ELF targets currently use 64-bit archives, 64-bit archives are enabled by default for them. 64-bit archive is generated automatically if the archive is too big. Tested on Linux/x86 and Linux/x86-64 with existing ld and gold. bfd/ PR binutils/14625 * archive.c (bfd_slurp_armap): Replace bfd_elf64_archive_slurp_armap with _bfd_archive_64_bit_slurp_armap.

64-bit format when creating an archive symbol index.
Properly implement STT_COMMON The BFD configure option, --enable-elf-stt-common, can't be to used to verify STT_COMMON implementation with the normal binutils build. Instead, this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF assembler/objcopy and adds -z common/-z nocommon to ld. A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default. Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF common symbols. bfd/ PR ld/19645 * bfd.c (bfd): Change flags to 20 bits. (BFD_CONVERT_ELF_COMMON): New.

the -u / --unwind option.
* Add --dyn-syms to readelf to dump dynamic symbol table.
2010-01-11 20:40:45 +08:00
* A new tool - elfedit - has been added to directly manipulate ELF format
binaries.
* Add to dlltool .def file feature of aliasing PE internal symbol name by
'== <ID>' option.

address before function name or source filename.
* Add a new command line option -p / --pretty-print to addr2line to have
a more human readable output.
* The hppa/som targets can now be compiled on any host.
Changes in 2.20:
* Add support for delay importing to dlltool. Use the --output-delaylib <file>
switch to create a delay-import library. The resulting app will load the dll
as soon as the first function is called. It will link to __delayLoadHelper2()
from the static delayimp library, which will import LoadLibraryA and
GetProcAddress from kernel32.
* Add a new command line option, --insn-width=WIDTH, to objdump to specify
number of bytes to be displayed on a single line when disassembling
instructions.
* Readelf can now display the relocated contents of a section as a sequence
of bytes via the --relocated-dump=<name|number> command line option.
* The gprof program has been given a new command line option:
--external-symbols-table=<filename> which reads in symbols from a specified
file.
* The plugin target has been added to bfd. It can load the same shared objects
used by gold and uses them to provide basic support for new file formats.
* The verilog memory hex dump file format is now supported as an output format
for objcopy.

* Add --file-alignment, --heap, --image-base, --section-alignment,
--stack and --subsystem command line options to objcopy, which will
set PE optional header.
* Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w.
* --as-needed now links in a dynamic library if it satisfies undefined
symbols in regular objects, or in other dynamic libraries. In the
latter case the library is not linked if it is found in a DT_NEEDED
entry of one of the libraries already linked.
* Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to
add absolute paths for -S.
* Add new option --use-nul-prefixed-import-tables to dlltool to allow fall-
back to old import table generation with null element prefix.
2015-08-12 19:42:37 +08:00
* Added --identify-strict switch to cause --identify <implib> to

2008-03-28 14:49:44 +08:00
* Added support for "thin" archives which contain pathnames pointing to
object files rather than the files themselves and which contain a
flattened symbol index for all objects, and archives, which have been
added to the archive.
2015-08-12 19:42:37 +08:00
* Added -F switch to objdump to include file offsets in the disassembly.
* Added -c switch to readelf to allow string dumps of archive symbol index.
2007-09-15 02:21:09 +08:00
* Support for SSE5 has been added to the i386 port.
* Added -p switch to readelf to allow string dumps of sections.
Changes in 2.18:
2007-08-28 19:56:08 +08:00
* Resolved 37 coding problems in bfd including static array overruns, null
pointer dereferences and use of a malloc buffer after it has been freed, as
revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com).
2002-07-18 19:11:13 +08:00
2007-07-06 00:54:46 +08:00
* The binutils sources are now released under version 3 of the GNU General
Public License.
* A new tool "windmc" has been added for some targets. This is a message
compiler which attempts to be compatible with the MS version.
* Add codepage support to the windres tool. It now supports many new
resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation
for binary files is done now via bfd itself. The endianess problems
for different hosts are solved. Dumps of .res files can now be
re-compiled by windres without lossing resources or compilation errors.
Some problems on dialog resource translations are corrected.
* Add --extract-symbol command line option to objcopy, which will
strip everything out of an ordinary object file or executable except
for its symbol table. Files containing just symbols can be useful
to some OSes.
2007-07-06 00:54:46 +08:00
Changes in 2.17:
* Add "-x NAME" to readelf in addition to "-x NUMBER".
* Add -i and -t switches to cxxfilt. -i disables the display of implementation
specific extra demangling information (if any) and -t disables the demangling
of types.
* Add support for the "@<file>" syntax to the command lines of all tools, so
that extra switches can be read from <file>.
* Add "-W/--dwarf" to objdump to display the contents of the DWARF
debug sections.
* Add "-t/--section-details" to readelf to display section details.
"-N/--full-section-name" is deprecated.
* powerpc-linux ld now supports a variant form of PLT and GOT for the security
conscious. This form will automatically be chosen when ld detects that all
code in regular object files was generated by gcc -msecure-plt. The old PLT
and GOT may be forced by a new ld option, --bss-plt.
* Add "-i/--inlines" to addr2line to print enclosing scope information
for inlined function chains, back to first non-inlined function.
* Add "-N/--full-section-name" to readelf to display full section name.
* Add "-M entry:<addr>" switch to objdump to specify a function entry address
when disassembling VAX binaries.
* Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches
to objcopy to convert local symbols into global symbols.
2015-08-12 19:42:37 +08:00
* gprof now allows input files to have histogram records for
2015-08-12 19:42:37 +08:00
several memory ranges, provided those ranges are disjoint.
Changes in 2.16:
* Add "-g/--section-groups" to readelf to display section groups.
* objcopy recognizes two new options --strip-unneeded-symbol and
--strip-unneeded-symbols, namely for use together with the wildcard
matching the original --strip-symbol/--strip-symbols provided, but
retaining any symbols matching but needed by relocations.
* readelf can now display address ranges from .debug_range sections. This
happens automatically when a DW_AT_range attribute is encountered. The
command line switch --debug-dump=Ranges (or -wR) can also be used to display
the contents of the .debug_range section.
* nm and objdump now have a switch "--special-syms" to enable the displaying of
symbols which the target considers to be special. By default these symbols
are no longer displayed. Currently the only special symbols are the Mapping
symbols used by the ARM port to mark transitions between text and data and
between ARM and THUMB code.
* dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional
import and export symbols with <preifx> prepended to them.
Changes in 2.15:
* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the
2005-01-20 07:43:00 +08:00
disassembler to print the "raw" mips instruction mnemonic instead of some
pseudo instruction name. I.E. print "daddu" or "or" instead of "move",
"sll" instead of "nop", etc.
* objcopy and strip can now take wildcard patterns in symbol names specified on
the command line provided that the --wildcard switch is used to enable them.
* readelf can now parse archives.
* objdump now accepts --debugging-tags to print the debug information in a
format compatible with ctags tool.
2003-06-26 16:14:10 +08:00
* objcopy and strip now accept --only-keep-debug to create a file containing
those sections that would be stripped out by --strip-debug. The idea is that
this can be used in conjunction with the --add-gnu-debuglink switch to create
a two part program distribution - one a stripped executable and the other the
debugging info.
* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink
section into a (presumably stripped) executable. This allows the debug
information for the file to be held in a separate file.
2015-08-12 19:42:37 +08:00
* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX
single-character representation. This can be checked by running nm
with the -a switch.
Changes in 2.14:
2003-03-25 00:11:46 +08:00
* Added --info switch to objcopy and strip.
* Support for Vitesse IQ2000 added by Red Hat.
* Added 'S' encoding to strings to allow the display of 8-bit characters.
* Added --prefix-symbols=<text>, --prefix-sections=<text> and
--prefix-alloc-sections=<text> to objcopy.
* readelf can handle the extensions to the DWARF2 spec used by the Unified
Parallel C compiler.
* BFD no longer declares a "boolean" type, to avoid clashes with other
headers that declare the same. Users of BFD should replace boolean,
false and true, with int, 0 and 1, or define their own boolean type.
2002-07-18 19:11:13 +08:00
* Support for IP2K added by Denis Chertykov.
2002-07-16 15:58:34 +08:00
Changes in 2.13:
* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
and FR500 included.
1999-05-03 15:29:11 +08:00
2002-02-20 18:46:54 +08:00
Changes in version 2.12:
2002-02-15 12:04:03 +08:00
* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
2002-01-25 23:37:04 +08:00
* size: Add --totals to display summary of sizes (Berkeley format only).
* readelf: Add --wide option to not break section header or segment listing
lines to fit into 80 columns.
* strings: Add --encoding to display wide character strings. By Markus Kuhn.
2001-07-31 21:49:39 +08:00
* objcopy: Add --rename-section to change section names.
* readelf: Support added for DWARF 2.1 extensions. Support added for
displaying the contents of .debug.macinfo sections.
* New command line switches added to objcopy to allow symbols to be kept as
global symbols, and also to specify files containing lists of such symbols.
by Honda Hiroki.
2001-04-27 21:34:20 +08:00
* Support for OpenRISC by Johan Rydberg.
* New command line switch to objcopy --alt-machine-code which creates a binary
with an alternate machine code if one is defined in the architecture
description. Only supported for ELF targets. By Alexandre Oliva.
* New command line switch to objcopy -B (or --binary-architecture) which sets
the architecture of the output file to the given argument. This option only
makes sense, if the input target is binary. Otherwise it is ignored.
By Stefan Geuken.
2001-02-19 07:33:11 +08:00
* Support for PDP-11 by Lars Brinkhoff.
Changes in binutils 2.11:
2000-11-25 08:21:40 +08:00
* Add support for ARM v5t and v5te architectures and Intel's XScale ARM
extenstions.
* Add --srec-len and --srec-forceS3 command line switch to objcopy.
By Luciano Gemme.
2000-09-14 09:47:38 +08:00
* Support for the MIPS32, by Anders Norlander.
* Support for the i860, by Jason Eckhardt.
2000-08-25 01:42:52 +08:00
* Support for CRIS (Axis Communications ETRAX series).
1999-05-03 15:29:11 +08:00
Changes in binutils 2.10:
* Support for 64-bit ELF on HPPA.
* New command line switch to objdump --file-start-context which shows the
entire file contents up to the source line first encountered for a given
file.
* New command line switch to objdump -M (or --disassembler-options) which takes
a parameter which can then be interpreted on a per-target basis by the
disassembler. Used by ARM targets to select register name sets, ISA, APCS or
raw verions.
1999-05-28 04:48:12 +08:00
* objdump support for -mi386:intel which causes disassembly to be displayed
with intel syntax.
1999-05-03 15:29:11 +08:00
* New program: readelf. This displays the contents of ELF format files,
regardless of target machine.
* objcopy now takes --change-section-lma, --change-section-vma, and
--change-section-address options. The old --adjust-section-vma option is
equivalent to --change-section-address. The other --adjust-* options are now
renamed to --change-*, although --adjust-* continues to work.
2000-04-05 11:43:56 +08:00
* objcopy has a --redefine-sym option that lets you rename symbols.
* objcopy now takes a -j/--only-section option to copy only the specified
sections.
1999-05-03 15:29:11 +08:00
* dlltool now supports the IMPORTS command.
* dlltool now takes --export-all-symbols, --no-export-all-symbols,
--exclude-symbols, and --no-default-excludes options.
Changes in binutils 2.9:
* Added windres program, which can be used to manipulate resources in WIN32
files as used on Windows 95 and Windows NT.
* The objcopy --gap-fill and --pad-to options operate on the LMA rather than
the VMA of the sections.
* Added S modifier to ar to not build a symbol table.
Changes in binutils 2.8:
* The objdump disassembly format has been changed, and hopefully improved. Use
the new --prefix-addresses option to get the old format. There are also new
--disassemble-zeroes and --no-show-raw-insn options which affect disassembler
output.
* Formats may now be specified as configuration triplets. For example,
objdump -b i386-pc-linux. The triplets are not passed through config.sub,
so they must be in canonical form.
* Added new addr2line program. This uses the debugging information to convert
an address into a file name and line number within a program.
* Added --change-leading-char argument to objcopy.
* Added --weaken argument to objcopy.
* objdump --dynamic-reloc now works on ELF executables and shared libraries.
* Added --adjust-vma option to objdump.
* Added -C/--demangle option to objdump.
* Added -p/--preserve-dates option to strip and objcopy.
Changes in binutils 2.7:
* Added --enable-shared and --enable-commonbfdlib options to configure.
* Added --debugging argument to objdump and objcopy.
* Added --defined-only argument to nm.
* Added --remove-leading-char argument to objcopy.
* The objdump --line-numbers option is now meaningful with --reloc.
* Added --line-numbers option to nm.
* Added --endian/-EB/-EL option to objdump.
* Added support for Alpha OpenVMS/AXP.
Changes in binutils 2.6:
* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy.
* Added several arguments to objcopy to provide some control over how the new
file is laid out in memory. Also added binary output format to BFD to permit
generating plain binary files.
* Added --start-address and --stop-address options to objdump.
* ar and ranlib now work on AIX. The tools are now built by default on AIX.
Changes in binutils 2.5:
* Changed objdump -dr to dump the relocs interspersed with the assembly
2003-06-25 14:40:27 +08:00
listing, for a more useful listing of relocatable files.
1999-05-03 15:29:11 +08:00
* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections.
Added -D/--disassemble-all option to disassemble all sections.
* Added --size-sort option to nm.
* strip and objcopy should now be able to handle dynamically linked ELF
executables.
Changes in binutils 2.4:
* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and
PowerPC (except ar and ranlib; by Ian Taylor).
* Support for Irix 5.
* Programs `strip' and `objcopy' will not attempt to write dynamically linked
ELF output files, since BFD currently can't create them properly.
Changes in binutils 2.3:
* A new --stabs argument has been added to objdump to dump stabs sections in
ELF and COFF files.
* A new program, nlmconv, has been added. It can convert object files into
Novell NetWare Loadable Modules.
* The strings program has been added.
Changes in binutils 2.2:
* The 'copy' program has been renamed to 'objcopy', for consistency with
'objdump', and because 'copy' might more plausibly be used as a synonym for
'cp'.
* The new stand-alone program c++filt is a filter that converts encoded
(mangled) C++ assembly-level identifiers to user-level names. (Note: This
may get moved to the gcc distribution.)
* nm -o on an archive now prefixes each line with the archive name, matching
the output from BSD nm.
* ar (and ld) can now read (but not write) BSD4.4-style archives.
* New support for H8500, Z8000, and the Hitach SH.
* Dis-assembler interface changed to allow sharing with gdb.
* There is new Elf code, but it is not yet ready for general use.
* There is the beginnings of a test suite.
Changes in binutils 2.1:
* There is now support for writing ECOFF files, so ld and the other utilities
should work on Risc/Ultrix and Irix. Please let us know how well this works.
* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD
version), if there are any object files in the archive. So running ranlib is
now redundant (unless the non-standard q command is used). This is required
for Posix.2 conformance.
* The archive-reading code now reads both BSD-style and SYSV-style archives
independently of the selected target format. This is to encourage people to
switch to SYSV-format, which has a number of advantages.
* The strip and copy programs now have options to remove debug-symbols only
and/or local symbols only. They now also support long options.
