Changes in 2.21:
|
||
|
||
|
||
* Add --interleave-width option to objcopy to allowing copying a range of
|
||
bytes from the input to the output with the --interleave option.
|
||
|
||
* Add support for the TMS320C6000 (TI C6X) processor family.
|
||
|
||
* Readelf can now display ARM unwind tables (.ARM.exidx / .ARM.extab) using
|
||
the -u / --unwind option.
|
||
|
||
* Add --dyn-syms to readelf to dump dynamic symbol table.
|
||
|
||
* 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.
|
||
|
||
* Add a new command line option -a / --addresses to addr2line to display the
|
||
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.
|
||
|
||
* Added --identify-strict switch to cause --identify <implib> to
|
||
report an error when the import library is associated with
|
||
multiple DLLs.
|
||
|
||
* Added --identify <implib> option to dlltool, which determines the
|
||
name of the DLL associated with the specified <implib>.
|
||
|
||
* Support for PowerPC booke64 instructions has been removed. The assembler no
|
||
longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts
|
||
-Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used.
|
||
|
||
Changes in 2.19:
|
||
|
||
* Added -wL switch to dump decoded contents of .debug_line.
|
||
|
||
* 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.
|
||
|
||
* 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.
|
||
|
||
* 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:
|
||
|
||
* 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).
|
||
|
||
* 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.
|
||
|
||
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.
|
||
|
||
* gprof now allows input files to have histogram records for
|
||
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
|
||
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.
|
||
|
||
* 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.
|
||
|
||
* 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:
|
||
|
||
* 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.
|
||
|
||
* Support for IP2K added by Denis Chertykov.
|
||
|
||
Changes in 2.13:
|
||
|
||
* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
|
||
and FR500 included.
|
||
|
||
Changes in version 2.12:
|
||
|
||
* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
|
||
|
||
* 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.
|
||
|
||
* 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.
|
||
|
||
* 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.
|
||
|
||
* Support for PDP-11 by Lars Brinkhoff.
|
||
|
||
Changes in binutils 2.11:
|
||
|
||
* 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.
|
||
|
||
* Support for the MIPS32, by Anders Norlander.
|
||
|
||
* Support for the i860, by Jason Eckhardt.
|
||
|
||
* Support for CRIS (Axis Communications ETRAX series).
|
||
|
||
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.
|
||
|
||
* objdump support for -mi386:intel which causes disassembly to be displayed
|
||
with intel syntax.
|
||
|
||
* 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.
|
||
|
||
* 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.
|
||
|
||
* 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
|
||
listing, for a more useful listing of relocatable files.
|
||
|
||
* 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.
|
||
|
||
|
||
Local variables:
|
||
fill-column: 79
|
||
