* 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.

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.

|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
* Add support for the "@<file>" syntax to the command lines of all tools, so
|
|
|
|
|
that extra switches can be read from <file>.
|

|
|
2005-10-03 22:40:19 +08:00

* powerpc-linux ld now supports a variant form of PLT and GOT for the security
|
|
|
|
|

|
|
|
|
|
code in regular object files was generated by gcc -msecure-plt. The old PLT
|
|
|
|
|

|
|
2005-05-24 01:45:42 +08:00

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

* 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.
|
|
|
|
|
|
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
|
|
|
|
|
command line switch --debug-dump=Ranges (or -wR) can also be used to display
|
|
|
|
|
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
|
|
|
|
|
import and export symbols with <preifx> prepended to them.

|
|
|
|
2005-01-20 07:35:26 +08:00
|
|
|
|
* 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
|
|
|
|
* 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.
|
|
|
|
|
|
2003-08-11 17:15:55 +08:00
|
|

* readelf can now parse archives.
|
|
|
|
|
|
2003-07-22 21:33:32 +08:00
|
|
|
|
* 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.
|
|
|
|
|
|
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.

|
|
with the -a switch.

|
|
* 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
|
|
|

|
|
|
|
2001-09-14 19:32:25 +08:00

|
* readelf: Support added for DWARF 2.1 extensions. Support added for
|
|
|
|
|
displaying the contents of .debug.macinfo sections.
|
|
|
|
|
|
2001-05-30 18:46:28 +08:00
|
|
|
|
* 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

|
|
|
2001-08-24 21:56:11 +08:00
|
|
|
|
* 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.
|
|
|
|
|
|
2001-03-13 08:08:35 +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.

|
|
|
|
|
2001-02-19 07:33:11 +08:00

|
|
|
|
|
1999-05-03 15:29:11 +08:00
|
|
|
|
Changes in binutils 2.10:
|
|
|
|
|
|
2001-06-09 10:15:49 +08:00
|
|
|
|
* Support for 64-bit ELF on HPPA.
|
|
|
|
|
|
2000-02-09 02:38:13 +08:00
|
|
|
|
* 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
|
2002-12-08 11:38:03 +08:00
|
|
|
|
file.
|
2000-02-09 02:38:13 +08:00
|
|
|
|
|
1999-06-16 10:24:36 +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.
|
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.
