* 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.
Changes in 2.34:
Add support for debuginfod to the binutils (disable by default, enabled via a configure time option). debuginfod is a lightweight web service that indexes ELF/DWARF debugging resources by build-id and serves them over HTTP. This patch enables objdump and readelf to query debuginfod servers when they are otherwise not able to find separate debug files. Binutils can be built with debuginfod using the --with-debuginfod configure option. This requires that libdebuginfod be installed and found at configure time. debuginfod is packaged with elfutils, starting with version 0.178. For more information see https://sourceware.org/elfutils/. toplevel* config/debuginfod.m4: New file. Add macro AC_DEBUGINFOD. Adds new configure option --with-debuginfod. * configure: Regenerate. * configure.ac: Call AC_DEBUGINFOD. binutils* Makefile.am (readelf_LDADD, objdump_LDADD): Add libdebuginfod. * Makefile.in: Regenerate. * NEWS: Update. * config.in: Regenerate. * configure: Regenerate. * configure.ac: Call AC_DEBUGINFOD. * doc/Makefile.in: Regenerate. * doc/binutils.texi: Add section on using binutils with debuginfod. * dwarf.c (debuginfod_fetch_separate_debug_info): New function.

* 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.
* Add --output option to the "ar" program. This option can be used to specify
the output directory when extracting members from an archive.
* Add --keep-section option to objcopy and strip. This option keeps the
specified section from being removed.
* 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:
c6: | | \----------> be 00 00 00 00 mov $0x0,%esi
cb: | | /----> 48 8b 3d 00 00 00 00 mov 0x0(%rip),%rdi # d2 <main+0xd2>
d2: | | | 31 c0 xor %eax,%eax
d4: | | | /-- e8 00 00 00 00 callq d9 <main+0xd9>
d9: | | | \-> bf 02 00 00 00 mov $0x2,%edi

eb: | \----- eb de jmp cb <main+0xcb>
ed: \-------------------> 48 8b 16 mov (%rsi),%rdx
Additional arguments to the --visualize-jumps option add colors to the
output.
Changes in 2.33:
* Add --source-comment[=<txt>] option to objdump which if present,
provides a prefix to source code lines displayed in a disassembly.
* Add --set-section-alignment <section-name>=<align> option to objcopy to allow
the changing of section alignments.
* Add --verilog-data-width option to objcopy for verilog targets to control
width of data elements in verilog hex format.
* Add support for the Armv8.1-M Mainline and M-profile Vector Extension (MVE)
instructions.

* 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).
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.

The --no-recurse-limit option can be used to remove the limit, restoring

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. binutils/ChangeLog: * size.c (berkeley_format): Delete. (enum output_format): New enum. (selected_output_format): New variable. (usage): Update to mention GNU format. (main): Update to extract options, and select format as needed. Handle GNU format where needed.

* The size tool now has a new output format '--format=GNU' or '-G'. The

except read-only data is counted in the data column, not the text column.
Additionally the total is only included once.

* Add support for disassembling netronome Flow Processor (NFP) firmware files.
Allow non-fatal errors to be emitted and for disassembly notes be placed on AArch64 This patch adds a new platform option "notes" that can be used to indicate if disassembly notes should be placed in the disassembly as comments. These notes can contain information about a failing constraint such as reading from a write-only register. The disassembly will not be blocked because of this but -M notes will emit a comment saying that the operation is not allowed. For assembly this patch adds a new non-fatal status for errors. This is essentially a warning. The reason for not creating an actual warning type is that this causes the interaction between the ordering of warnings and errors to be problematic. Currently the error buffer is almost always filled because of the way operands are matched during assembly. An earlier template may have put an error there that would only be displayed if no other template matches or generates a higher priority error. But by definition a warning is lower priority than a warning, so the error (which is incorrect if another template matched) will supersede the warning. By treating warnings as errors and only later relaxing the severity this relationship keeps working and the existing reporting infrastructure can be re-used. binutils/ PR binutils/21446 * doc/binutils.texi (-M): Document AArch64 options. * NEWS: Document notes and warnings. gas/ PR binutils/21446 * config/tc-aarch64.c (print_operands): Indicate no notes.

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).

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.

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.

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
Fix use of "command line X" in binutils doc Binutils documentation uses a mix of spelling for the compound word "command-line X". According to [1]: "Sometimes compound words are written separately (nail polish), sometimes with a hyphen (short-sighted) and sometimes as one word (eyelashes). Often new compounds are written as two separate words and, as they become more familiar, they are either connected with a hyphen (-) or made into one word." I think command-line X is common enough in our industry that the two workds command and line should be connected. Since command-line is more common than commandline, I propose to update binutils documentation to consistently use "command-line" when this is used as an adjective to a noun (eg. command-line argument, command-line switch, command-line option and command-line flag). I've left occurences of "the command line" as is. I've also left gdb, sim and readline alone and have only touched public documentation (texi and NEWS files).

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'.

* 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.

* Add a configure option, --enable-64-bit-archive, to force use of a
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.

Changes in 2.24:
Fix use of "command line X" in binutils doc Binutils documentation uses a mix of spelling for the compound word "command-line X". According to [1]: "Sometimes compound words are written separately (nail polish), sometimes with a hyphen (short-sighted) and sometimes as one word (eyelashes). Often new compounds are written as two separate words and, as they become more familiar, they are either connected with a hyphen (-) or made into one word." I think command-line X is common enough in our industry that the two workds command and line should be connected. Since command-line is more common than commandline, I propose to update binutils documentation to consistently use "command-line" when this is used as an adjective to a noun (eg. command-line argument, command-line switch, command-line option and command-line flag). I've left occurences of "the command line" as is. I've also left gdb, sim and readline alone and have only touched public documentation (texi and NEWS files).

Fix use of "command line X" in binutils doc Binutils documentation uses a mix of spelling for the compound word "command-line X". According to [1]: "Sometimes compound words are written separately (nail polish), sometimes with a hyphen (short-sighted) and sometimes as one word (eyelashes). Often new compounds are written as two separate words and, as they become more familiar, they are either connected with a hyphen (-) or made into one word." I think command-line X is common enough in our industry that the two workds command and line should be connected. Since command-line is more common than commandline, I propose to update binutils documentation to consistently use "command-line" when this is used as an adjective to a noun (eg. command-line argument, command-line switch, command-line option and command-line flag).

from the static delayimp library, which will import LoadLibraryA and
GetProcAddress from kernel32.

Fix use of "command line X" in binutils doc Binutils documentation uses a mix of spelling for the compound word "command-line X". According to [1]: "Sometimes compound words are written separately (nail polish), sometimes with a hyphen (short-sighted) and sometimes as one word (eyelashes). Often new compounds are written as two separate words and, as they become more familiar, they are either connected with a hyphen (-) or made into one word." I think command-line X is common enough in our industry that the two workds command and line should be connected. Since command-line is more common than commandline, I propose to update binutils documentation to consistently use "command-line" when this is used as an adjective to a noun (eg. command-line argument, command-line switch, command-line option and command-line flag). I've left occurences of "the command line" as is. I've also left gdb, sim and readline alone and have only touched public documentation (texi and NEWS files).

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.

added to the archive.
2015-08-12 19:42:37 +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.

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 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.

2018-07-02 18:18:24 +08:00
* 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.
