We are pleased to announce that version 2.37 of the GNU Binutils project
sources have been released and are now available for download at:
This release contains numerous bug fixes, and also the
following new features:
* The GNU Binutils sources now requires a C99 compiler and library to
* Support for the arm-symbianelf format has been removed.
* Support for Realm Management Extension (RME) for AArch64 has been
* A new linker option '-z report-relative-reloc' for x86 ELF targets
has been added to report dynamic relative relocations.
* A new linker option '-z start-stop-gc' has been added to disable
special treatment of __start_*/__stop_* references when
* A new linker options '-Bno-symbolic' has been added which will
cancel the '-Bsymbolic' and '-Bsymbolic-functions' options.
* The readelf tool has a new command line option which can be used to
specify how the numeric values of symbols are reported.
--sym-base=0|8|10|16 tells readelf to display the values in base 8,
base 10 or base 16. A sym base of 0 represents the default action
of displaying values under 10000 in base 10 and values above that in
* 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.
* A new command line option '--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.
* The '--weaken', '--weaken-symbol' and '--weaken-symbols' options
supported by objcopy now make undefined symbols weak on targets that
support weak symbols.
* Readelf and objdump can now display and use the contents of .debug_sup
* 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.
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.
* Nm has a new command line option: '--quiet'. This suppresses "no
Our thanks go out to all of the binutils contributors, past and
present, for helping to make this release possible.
