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.
|
||
|
||
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 relocateable 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
