2021-03-15 18:55:49 +08:00
|
|
|
|
* A new format has been added to the nm program. Specifying
|
|
|
|
|
|
--format=just-symbols (or just using -j) will tell the program to only
|
|
|
|
|
|
display symbol names and nothing else.
|
|
|
|
|
|
|
2021-03-04 18:41:22 +08:00
|
|
|
|
* A new command line --keep-section-symbols has been added to objcopy and
|
|
|
|
|
|
strip. This stops the removal of unused section symbols when the file is
|
|
|
|
|
|
copied. Removing these symbols saves space, but sometimes they are needed by
|
|
|
|
|
|
other tools.
|
|
|
|
|
|
|
2021-03-03 12:45:23 +08:00
|
|
|
|
* objcopy --weaken, --weaken-symbol and --weaken-symbols now make undefined
|
|
|
|
|
|
symbols weak on targets that support weak symbols.
|
|
|
|
|
|
|
2021-02-26 01:50:44 +08:00
|
|
|
|
* Readelf and objdump can now display and use the contents of .debug_sup
|
|
|
|
|
|
sections.
|
|
|
|
|
|
|
2021-02-12 22:52:22 +08:00
|
|
|
|
* Readelf and objdump will now follow links to separate debug info files by
|
|
|
|
|
|
default. This behaviour can be stopped via the use of the new -wN or
|
|
|
|
|
|
--debug-dump=no-follow-links options for readelf and the -WN or
|
|
|
|
|
|
--dwarf=no-follow-links options for objdump. Also the old behaviour can be
|
|
|
|
|
|
restored by the use of the --enable-follow-debug-links=no configure time
|
|
|
|
|
|
option.
|
|
|
|
|
|
|
2021-03-04 18:41:22 +08:00
|
|
|
|
The semantics of the =follow-links option have also been slightly changed.
|
|
|
|
|
|
When enabled, the option allows for the loading of symbol tables and string
|
|
|
|
|
|
tables from the separate files which can be used to enhance the information
|
|
|
|
|
|
displayed when dumping other sections, but it does not automatically imply
|
|
|
|
|
|
that information from the separate files should be displayed.
|
|
|
|
|
|
|
|
|
|
|
|
If other debug section display options are also enabled (eg
|
|
|
|
|
|
--debug-dump=info) then the contents of matching sections in both the main
|
|
|
|
|
|
file and the separate debuginfo file *will* be displayed. This is because in
|
|
|
|
|
|
most cases the debug section will only be present in one of the files.
|
|
|
|
|
|
|
|
|
|
|
|
If however non-debug section display options are enabled (eg --sections) then
|
|
|
|
|
|
the contents of matching parts of the separate debuginfo file will *not* be
|
|
|
|
|
|
displayed. This is because in most cases the user probably only wanted to
|
|
|
|
|
|
load the symbol information from the separate debuginfo file. In order to
|
|
|
|
|
|
change this behaviour a new command line option --process-links can be used.
|
|
|
|
|
|
This will allow di0pslay options to applied to both the main file and any
|
|
|
|
|
|
separate debuginfo files.
|
|
|
|
|
|
|
2021-02-27 01:25:45 +08:00
|
|
|
|
* Nm has a new command line option: --quiet. This suppresses "no symbols"
|
|
|
|
|
|
diagnostic.
|
|
|
|
|
|
|
2021-01-09 18:40:28 +08:00

Changes in 2.36:
|
|
|
|
|
|
|
2020-12-24 05:00:39 +08:00
|
|
|
|
* Update elfedit and readelf with LAM_U48 and LAM_U57 support.
|
|
|
|
|
|
|
2020-11-20 21:04:56 +08:00
|
|
|
|
* Nm has a new command line option: --ifunc-chars=CHARS. This specifies a
|
|
|
|
|
|
string of one or two characters. The first character is used as the type
|
|
|
|
|
|
character when displaying global ifunc symbols. The second character, if
|
|
|
|
|
|
present is used when displaying local ifunc symbols.
|
|
|
|
|
|
|
|
|
|
|
|
In addition a new configure time option --enable-f-for-ifunc-symbols has been
|
|
|
|
|
|
created, which if used will change nm's default characters for ifunc symbols
|
|
|
|
|
|
from i (both local and global) to F (global) and f (local).
|
|
|
|
|
|
|
2020-11-03 23:12:47 +08:00
|
|
|
|
* The ar tool's previously unused l modifier is now used for specifying
|
|
|
|
|
|
dependencies of a static library. The arguments of this option
|
|
|
|
|
|
(or --record-libdeps long form option) will be stored verbatim in the
|
|
|
|
|
|
__.LIBDEP member of the archive, which the linker may read at link time.
|
|
|
|
|
|
|
2020-10-19 22:27:58 +08:00
|
|
|
|
* Readelf can now display the contents of LTO symbol table sections when asked
|
|
|
|
|
|
to do so via the --lto-syms command line option.
|
|
|
|
|
|
|
2020-08-12 20:31:59 +08:00
|
|
|
|
* Readelf now accepts the -C command line option to enable the demangling of
|
|
|
|
|
|
symbol names. In addition the --demangle=<style>, --no-demangle,
|
|
|
|
|
|
--recurse-limit and --no-recurse-limit options are also now availale.
|
|
|
|
|
|
|
2020-11-18 19:51:13 +08:00
|
|
|
|
* Add support for the SHF_GNU_RETAIN ELF section flag.
|
|
|
|
|
|
This flag specifies that the section should not be garbage collected by the
|
|
|
|
|
|
linker.
|
|
|
|
|
|
|
2020-07-04 17:16:22 +08:00
|
|
|
|
Changes in 2.35:
|
|
|
|
|
|
|
2020-07-02 18:30:52 +08:00
|
|
|
|
* Changed readelf's display of symbol names when wide mode is not enabled.
|
|
|
|
|
|
If the name is too long it will be truncated and the last five characters
|
|
|
|
|
|
replaced with "[...]". The old behaviour of displaying 5 more characters but
|
|
|
|
|
|
not indicating that truncation has happened can be restored by the use of the
|
|
|
|
|
|
-T or --silent-truncation options.
|
|
|
|
|
|
|
2020-06-30 23:47:02 +08:00
|
|
|
|
* X86 NaCl target support is removed.
|
|
|
|
|
|
|
2020-04-29 23:01:40 +08:00
|
|
|
|
* The readelf tool now has a -L or --lint or --enable-checks option which turns
|
|
|
|
|
|
on warning messages about possible problems with the file(s) being examined.
|
|
|
|
|
|
These checks include things like zero-sized sections, which are allowed by
|
|
|
|
|
|
the ELF standard but which nevertheless might be of concern if the user
|
|
|
|
|
|
was expecting them to actually contain something.
|
|
|
|
|
|
|
2020-01-18 21:50:25 +08:00

|
|
Changes in 2.34:
|
|
|
|
|
|
|
2020-01-09 21:19:20 +08:00
|
|
|
|
* Binutils now supports debuginfod, an HTTP server for distributing
|
|
|
|
|
|
ELF/DWARF debugging information as well as source code. When built with
|
|
|
|
|
|
debuginfod, readelf and objdump can automatically query debuginfod
|
|
|
|
|
|
servers for separate debug files when they otherwise cannot be found.
|
|
|
|
|
|
To build binutils with debuginfod, pass --with-debuginfod to configure.
|
|
|
|
|
|
This requires libdebuginfod, the debuginfod client library. debuginfod
|
|
|
|
|
|
is distributed with elfutils, starting with version 0.178. For more
|
|
|
|
|
|
information see https://sourceware.org/elfutils.
|
|
|
|
|
|
|
2019-10-30 18:50:23 +08:00
|
|
|
|
* Add --output option to the "ar" program. This option can be used to specify
|
|
|
|
|
|
the output directory when extracting members from an archive.
|
|
|
|
|
|
|
2019-11-02 05:47:55 +08:00
|
|
|
|
* Add --keep-section option to objcopy and strip. This option keeps the
|
|
|
|
|
|
specified section from being removed.
|
|
|
|
|
|
|
Add an option to objdump's disassembler to generate ascii art diagrams showing the destinations of flow control instructions.

2020-01-13 20:36:55 +08:00
|
|
|
|
* Add visualization of jumps inside a function by drawing an ascii character
|
|
|
|
|
|
graph between the address and the disassembler column. Enabled via the
|
|
|
|
|
|
--visualize-jumps command line option for objdump. Currently supported by
|
|
|
|
|
|
the x86, x86_64, and ARM targets. The output looks something like this:
|
|
|
|
|
|

Changes in 2.33:
|
|
|
|
|
|
|
2019-08-28 18:39:19 +08:00
|
|
|
|
* Add --source-comment[=<txt>] option to objdump which if present,
|
|
|
|
|
|
provides a prefix to source code lines displayed in a disassembly.
|
2010-01-11 22:45:42 +08:00
|
|
|
|
|
2019-08-28 19:33:41 +08:00
|
|
|
|
* Add --set-section-alignment <section-name>=<align> option to objcopy to allow
|
|
|
|
|
|
the changing of section alignments.
|
|
|
|
|
|
|
2019-05-14 17:40:04 +08:00
|
|
|
|
* Add --verilog-data-width option to objcopy for verilog targets to control
|
|
|
|
|
|
width of data elements in verilog hex format.
|
|
|
|
|
|
|
2019-05-16 23:08:36 +08:00
|
|
|
|
* Add support for the Armv8.1-M Mainline and M-profile Vector Extension (MVE)
|
|
|
|
|
|
instructions.
|
|
|
|
|
|
|
2019-02-22 18:36:24 +08:00
|
|
|
|
* The separate debug info file options of readelf (--debug-dump=links
|
|
|
|
|
|
and --debug-dump=follow) and objdump (--dwarf=links and
|
|
|
|
|
|
--dwarf=follow-links) will now display and/or follow multiple links if
|
|
|
|
|
|
more than one are present in a file. (This usually happens when gcc's
|
|
|
|
|
|
-gsplit-dwarf option is used).
|
|
|
|
|
|
|
2019-02-25 20:15:41 +08:00
|
|
|
|
In addition objdump's --dwarf=follow-links now also affects its other
|
|
|
|
|
|
display options, so that for example, when combined with --syms it will
|
|
|
|
|
|
cause the symbol tables in any linked debug info files to also be
|
|
|
|
|
|
displayed. In addition when combined with --disassemble the --dwarf=
|
|
|
|
|
|
follow-links option will ensure that any symbol tables in the linked
|
|
|
|
|
|
files are read and used when disassembling code in the main file.
|
binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

2019-04-24 19:04:33 +08:00
|
|
|
|
|
|
|
|
|
|
* Add support for dumping types encoded in the Compact Type Format
|
|
|
|
|
|
to objdump and readelf.
|
|
|
|
|
|
|
2019-01-19 23:55:50 +08:00

Changes in 2.32:
|
|
|
|
|
|
|
2018-12-07 19:32:55 +08:00
|
|
|
|
* The addr2line, c++filt, nm and objdump tools now have a limit on the
|
|
|
|
|
|
maximum amount of recursion that is allowed whilst demangling strings.
|
|
|
|
|
|
The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT
|
|
|
|
|
|
constant declared in the include/demangle.h header file. At the time
|
2018-12-11 20:01:15 +08:00
|
|
|
|
of writing this constant has the value of 2048.
|
2018-12-07 19:32:55 +08:00
|
|
|
|
|
|
|
|
|
|
The --no-recurse-limit option can be used to remove the limit, restoring
|
|
|
|
|
|
the behaviour of earlier versions of these tools. This may be needed in
|
|
|
|
|
|
order to dmangle truly complicated names, but it also leaves the tools
|
|
|
|
|
|
vulnerable to stack exhaustion from maliciously constructed mangled names.
|
|
|
|
|
|
|
2018-11-08 02:07:36 +08:00
|
|
|
|
* Objdump's --disassemble option can now take a parameter, specifying the
|
|
|
|
|
|
starting symbol for disassembly. Disassembly will continue from this
|
2019-01-17 23:29:43 +08:00
|
|
|
|
symbol up to the next symbol or the end of the function.
|

|
|
|
|
|
2018-08-29 20:55:25 +08:00
|
|
|
|
* The MIPS port now supports the Loongson 2K1000 processor which implements
|
|
|
|
|
|
the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE,
|
|
|
|
|
|
Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for
|
|
|
|
|
|
Loongson 2K1000 processor.
|
|
|
|
|
|
|
2018-08-29 20:36:23 +08:00

* The MIPS port now supports the Loongson 3A2000/3A3000 processor which
|
|
|
|
|
|
implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE,
|
|
|
|
|
|
Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e

binutils: Add new GNU format mode to `size` utility
The size tool currently defaults to berkeley format output. However,
this output format has a weird quirk, read-only data is counted
against the text sections, not the data sections.
The code offers no real explanation for why this is, but I'm reluctant
to change it for two reasons, first, I'm assuming it probably makes
sense in some case that I'm not thinking of (maybe a target where
sections are not marked executable, and so there's no distinction
between read-only data and code), and second, the code has been this
way for at least 20 years, I worry that changing things now might
cause more confusion than it solves.
This commit then introduces a new output format for the size tool,
this new format displays the results in a similar manor to the
berkeley format, but counts read-only data in the data column, and
only executable sections are counted in the text column.
Given that this is a brand new output format I've gone ahead and
simplified things a little, while the berkeley format displays the
total twice, once in decimal and once in hex, the new display format
just displays the total in decimal. Of course, there's still the
'--radix' option which can be used to display all the results in
hexadecimal or octal.
I've called the new format 'gnu', so '--format=gnu' or '-G' are used
to access it.

Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

MIPS16e2: Add MIPS16e2 ASE support
Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:
1. A new ELF ASE flag to mark MIPS16e2 binaries.
2. MIPS16e2 instruction assembly support, including a relaxation update
to use LUI rather than an LI/SLL instruction pair for loading the
high part of 32-bit addresses.
3. MIPS16e2 instruction disassembly support, including updated rules for
extended forms of instructions that are now subdecoded and therefore
do not alias to the original MIPS16 ISA revision instructions even
for encodings that are not valid in the MIPS16e2 instruction set.
Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops. Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.
Parts of this change by Matthew Fortune and Andrew Bennett.

Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX
Mark an ALLOC section, which should be placed in special memory area,
with SHF_GNU_MBIND. Its sh_info field indicates the special memory
type. GNU_MBIND section names start with ".mbind" so that they are
placed as orphan sections by linker. All input GNU_MBIND sections
with the same sh_type, sh_flags and sh_info are placed in one output
GNU_MBIND section. In executable and shared object, create a
GNU_MBIND segment for each GNU_MBIND section and its segment type is
PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is
aligned at page boundary.
The assembler syntax:
.section .mbind.foo,"adx",%progbits
^ 0: Special memory type.
|
'd' for SHF_GNU_MBIND.
.section .mbind.foo,"adx",%progbits,0x1

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.

* 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.

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.

|
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.

specific extra demangling information (if any) and -t disables the demangling
|
|
|

of types.
|
|
|
|
|
|
|
|

|
|
|
|
|
2004-12-16 21:16:33 +08:00

|
|
|
|
|
|
--strip-unneeded-symbols, namely for use together with the wildcard
|
|
|
|
|

retaining any symbols matching but needed by relocations.

2004-11-03 18:44:45 +08:00
|
|
|
|
* readelf can now display address ranges from .debug_range sections. This
|
|
|
|

happens automatically when a DW_AT_range attribute is encountered. The
|
2018-07-02 18:18:24 +08:00
|
|
|
|
command-line switch --debug-dump=Ranges (or -wR) can also be used to display

2004-11-03 18:44:45 +08:00
|
|
|
|
the contents of the .debug_range section.
|
|
|
|
|
|
|
2004-10-08 22:54:04 +08:00
|
|
|
|
* 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.
|
|
|
|
|
|
|
2004-07-13 01:07:55 +08:00
|
|
|
|
* dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional

|
* 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
|
2005-01-20 07:35:26 +08:00
|
|
|
|
pseudo instruction name. I.E. print "daddu" or "or" instead of "move",

"sll" instead of "nop", etc.

|
|
|
|

2003-11-12 01:50:26 +08:00

|
|
|
the command line provided that the --wildcard switch is used to enable them.

|
|
|
|
|
|
2003-08-11 17:15:55 +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.
|
|
|
|
|
|
|
2003-06-12 15:23:31 +08:00
|
|
|
|
* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink
|
|
|
|
|
|
section into a (presumably stripped) executable. This allows the debug
|
2003-10-27 21:20:32 +08:00
|
|
|
|
information for the file to be held in a separate file.

|
|
2003-06-04 01:45:49 +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.

|
|
|
|
* Added --info switch to objcopy and strip.

|
|
|
|
|
|
2003-01-04 10:13:46 +08:00
|
|
|
|
* Support for Vitesse IQ2000 added by Red Hat.
|
|
|
|
|
|
|
2002-12-23 18:37:38 +08:00
|
|
|
|
* Added 'S' encoding to strings to allow the display of 8-bit characters.
|
|
|
|
|
|
|
2002-12-13 21:19:44 +08:00
|
|

|
|
|
|
|
--prefix-alloc-sections=<text> to objcopy.

2002-12-11 01:48:27 +08:00
|
|
|
|
* readelf can handle the extensions to the DWARF2 spec used by the Unified
|
|
|
|
|
|
Parallel C compiler.
|
|
|
|
|
|
|
2002-12-08 11:38:03 +08:00
|
|
|
|
* 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

|
|
|
2001-07-05 15:49:05 +08:00
|
|
|
|
* readelf: Support added for DWARF 2.1 extensions. Support added for
|
|
|
|
|
|
displaying the contents of .debug.macinfo sections.
|
|
|
|
|
|
|
2018-07-02 18:18:24 +08:00
|
|
|
|
* New command-line switches added to objcopy to allow symbols to be kept as
|
2001-05-30 18:46:28 +08:00
|
|
|
|
global symbols, and also to specify files containing lists of such symbols.

|
|
|
|
2018-07-02 18:18:24 +08:00
|
|
|
|
* New command-line switch to objcopy -B (or --binary-architecture) which sets
|
2001-06-09 10:15:49 +08:00
|
|
|
|
the architecture of the output file to the given argument. This option only
|
2001-03-13 08:08:35 +08:00
|
|
|
|
makes sense, if the input target is binary. Otherwise it is ignored.

|
|
|
2018-07-02 18:18:24 +08:00
|
|
|

Changes in binutils 2.10:
|
|
|
|
|
|
|
2001-06-09 10:15:49 +08:00
|
|
|
|
* Support for 64-bit ELF on HPPA.
|
|
|
|
|
|
|
2018-07-02 18:18:24 +08:00
|
|
|
|
* New command-line switch to objdump --file-start-context which shows the
|
2000-02-09 02:38:13 +08:00
|
|
|
|
entire file contents up to the source line first encountered for a given
|
2002-12-08 11:38:03 +08:00
|
|
|
|
file.
|
2000-02-09 02:38:13 +08:00
|
|
|
|
|
2018-07-02 18:18:24 +08:00
|
|
|
|
* New command-line switch to objdump -M (or --disassembler-options) which takes
|
1999-06-16 10:24:36 +08:00
|
|
|
|
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.
|
2002-12-08 11:38:03 +08:00
|
|
|
|
|
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.
