|
|
|
|
|
|
2009-11-05 23:35:50 +08:00
|
|
|
|
* --add-needed renamed to --copy-dt-needed-entries in order to avoid confusion
|
|
|
|
|
with --as-needed option.
|
|
|
|
|
|
2009-10-23 19:40:17 +08:00
|
|
|
|
* Extend .def file syntax by '== <ID>' for imports and exports. This allows
|
|
|
|
|
to alias the import/export table name written in PE image.
|
|
|
|
|
|
2011-11-03 00:28:31 +08:00
|
|
|
|
* Add --exclude-all-symbols option to PE based linkers. This prevents all
|
2009-10-16 23:15:39 +08:00
|
|
|
|
symbols from automatically being exported.
|
|
|
|
|
|
2009-09-29 22:17:19 +08:00
|
|
|
|

|
|
|
|
|

2010-09-09 18:46:33 +08:00
|
|
|
|
* Add support for alpha-vms target.
|
|
|
|
|
|
2009-09-04 16:23:49 +08:00
|
|
|
|
Changes in 2.20:
|
|
|
|
|
|
2009-07-23 21:00:30 +08:00
|
|
|
|
* GNU/Linux targets now support the STB_GNU_UNIQUE symbol binding. This is a
|
|
|
|
|
GNU extension to the standard set of ELF symbol bindings. The binding will
|
|
|
|
|
be passed on to the dynamic linker which will make sure that in the entire
|
|
|
|
|
process there is just one symbol with the given name and type in use.
|
2009-01-08 21:28:48 +08:00
|
|
|
|
|
2009-05-20 00:08:08 +08:00
|
|
|
|
* PE targets now support a GNU extension to allow the alignment of common
|
|
|
|
|
common symbols to be specified. This support uses custom options in
|
|
|
|
|
the .drectve section, which will be disregarded by the native tools.
|
|
|
|
|
|
2009-05-04 20:09:30 +08:00
|
|
|
|
* PE targets now add primitive support for ELF version scripts; symbols
|
|
|
|
|
are not versioned, but the local and global symbol visibility directives
|
|
|
|
|
are respected when filtering symbols in auto-export mode.
|
|
|
|
|
|
2009-04-30 01:24:27 +08:00
|
|
|
|
* New option --no-export-dynamic to undo the effect of the -E and
|
|
|
|
|
--export-dynamic options.
|
|
|
|
|
|
2009-04-09 00:04:50 +08:00
|
|
|
|
* ELF: --warn-alternate-em option to warn if an object has alternate
|
|
|
|
|
ELF machine code.
|
|
|
|
|
|
2009-03-03 01:27:36 +08:00
|
|
|
|
* New script function REGION_ALIAS to add alias names to memory regions.
|
|
|
|
|
|
2009-02-19 02:23:08 +08:00
|
|
|
|
* PE targets no longer make use of the long section names PE extension to
|
|
|
|
|
the COFF format when generating executable images, by default. The old
|
|
|
|
|
(slightly non-conformant) behaviour can still be invoked by using the
|
2009-03-04 02:22:11 +08:00
|
|
|
|
new '--enable-long-section-names' command-line option. It is also enabled
|
|
|
|
|
automatically in the presence of un-stripped debug information, as GDB
|
|
|
|
|
needs to be able to find the debug info sections by their full names.
|
2009-02-19 02:23:08 +08:00
|
|
|
|
|
2009-04-30 23:47:13 +08:00
|
|
|
|
* For GNU/Linux systems the linker will now avoid processing any relocations
|
|
|
|
|
made against symbols of the STT_GNU_IFUNC type and instead emit them into
|
|
|
|
|
the resulting binary for processing by the loader.
|
|
|
|
|
|
2009-02-03 23:56:59 +08:00
|
|
|
|
* --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.
|
|
|
|

For the switch --enable-runtime-pseudo-reloc it uses for 32-bit
|
|
|
|
|
runtime pseudo relocation version one, for 64-bit the version two.

|
|
|
|
|
the --got=<type> command line option.
|
|
|
|
|
|
2008-09-07 12:02:31 +08:00
|
|
|
|

|
2007-03-30 01:16:05 +08:00
|
|
|
|
* -l:foo now searches the library path for a filename called foo,
|
|
|
|
|
without converting it to libfoo.a or libfoo.so.
|
|
|
|
|
|
2007-01-19 22:51:27 +08:00
|
|
|
|
* Add a new command line option '--default-script=FILE' or '-dT FILE'
|
|
|
|
|
which specifies a replacement for the built in, default linker
|
|
|
|
|
script.
|
|
|
|
|
|
2007-01-16 22:56:32 +08:00
|
|
|
|
* ELF: Add -Bsymbolic-functions, --dynamic-list-cpp-new, which puts C++
|
|
|
|
|
operator new and delete on the dynamic list, and --dynamic-list-data,
|
|
|
|
|
builtin list for --dynamic-list, which puts global data symbols on the
|
|
|
|
|
dynamic list.
|
|
|
|
|
|
2006-09-20 19:35:11 +08:00
|
|
|
|
* Add support for x86_64 PE+ target.
|
|
|
|
|
|
2006-09-17 07:51:50 +08:00
|
|
|
|
* Add support for Score target.
|
|
|
|
|
|
2006-09-08 01:16:34 +08:00
|
|
|
|
* ELF: Add --dynamic-list option to specify a list of global symbols
|
|
|
|
|
whose references shouldn't be bound to the definition within the
|
|
|
|
|
shared library, or a list of symbols which should be added to the
|
|
|
|
|
symbol table in the executable.
|
|
|
|
|
|
2006-08-22 15:41:05 +08:00
|
|
|
|
* The default output section LMA has changed for allocatable sections from
|
|
|
|
|
being equal to VMA, to keeping the difference between LMA and VMA the same as
|
|
|
|
|
the previous output section in the same region. This is a more useful
|
|
|
|
|
default when using overlays and other cases where you specify an LMA
|
|
|
|
|
differing from the VMA for some sections.
|
|
|
|
|
|
2006-08-04 22:53:26 +08:00
|
|
|
|
* New switch: --print-gc-sections to list any sections removed by garabge

|
|
|
|
|
|
2006-04-05 23:40:40 +08:00
|
|
|
|
* Modify the Linux linker search order to better match ld.so search order.
|
|
|
|
|
Look for DT_NEEDED libraries in paths specified by ld.so.conf before
|
|
|
|
|
searching the default directories, rather than vice versa.
|
|
|
|
|
Use $prefix/etc/ld.so.conf if it exists, otherwise /etc/ld.so.conf.
|
2006-02-09 09:05:10 +08:00
|
|
|

|
|
|
|
* Support for the Z80 processor family has been added.
|
|
|
|
|
|
2005-10-13 08:57:43 +08:00
|
|

* Support for the R_ARM_V4BX relocation as defined in the ARM AAELF
|
|
|
|
|
specification has been added via the --fix-v4bx command-line option.
|
|
|
|
|
|
2005-01-21 20:04:25 +08:00
|
|
|
|
* New linker script construct AS_NEEDED(), which sets the --as-needed flag
|
|
|
|
|
for input files listed inside of it.
|
|
|
|
|
|
2005-01-19 19:42:49 +08:00
|
|
|
|
* A new command-line option, --sysroot, can be used to override the
|
|
|
|
|
default sysroot location. It only applies to toolchains that were
|
|
|
|
|
configured using --with-sysroot.
|
|
|
|
|
|
2004-11-19 17:31:55 +08:00
|
|
|
|
* New linker script functions: ORIGIN() and LENGTH() which return information
|
|
|
|
|
about a specified memory region.
|
|

|
|
|
|
|
override the base address for a segment from the command-line.
|
|
|
|
|
|
2004-10-07 22:45:24 +08:00
|
|
|
|
* ELF: --warn-shared-textrel option to warn if adding a DT_TEXTREL to a shared
|
|
|
|
|
object.
|
|
|
|
|
|
2004-10-05 00:45:51 +08:00
|
|
|
|
* Added SORT_BY_NAME and SORT_BY_ALIGNMENT to the linker script
|
|
|
|
|
language to permit sorting sections by section name or section
|
|
|
|
|
maximum alignment.
|
|
|
|
|
|
|
|
|
|
* Added a new linker command line switch, --sort-section name|alignment,
|
|
|
|
|
to sort sections by section name or maximum alignment.
|
|
|
|
|
|
2004-10-07 22:45:24 +08:00
|
|
|
|
* ELF: --add-needed/--no-add-needed options to control if a DT_NEEDED tag
|
|
|
|
|
should be added when a shared library comes from DT_NEEDED tags.
|
2004-07-20 03:14:51 +08:00
|
|
|
|
|
2004-07-08 01:28:53 +08:00
|
|
|
|
* Support for the crx-elf target added.
|
|
|
|
|
|
2004-07-09 20:32:35 +08:00
|
|
|
|
* Support for the sh-symbianelf target added.
|
2004-07-08 01:28:53 +08:00
|
|
|
|
|
2004-05-21 23:38:04 +08:00
|
|
|
|
* A new linker command line switch has been added which allows the hash table
|
|
|
|
|
size to be set to a suitable prime value near to its argument. This switch
|
|
|
|
|
is --hash-size=<NUMBER>. Also if the switch --reduce-memory-overheads is
|
|
|
|
|
used, and --hash-size has not been used, then the default value will be set
|
|
|
|
|
to 1021.
|
|
|
|
|
|
2004-05-19 22:15:55 +08:00
|
|
|
|
* Linker map files are now generated with an O(N) algorithm for finding symbols
|
|
|
|
|
that are defined in each section. This uses about 40% more memory for
|
|
|
|
|
symbols than the old O(N^2) algorithm. You can use the new
|
|
|
|
|
--reduce-memory-overheads option to select the old algorithm; this option
|
|
|
|
|
might also be used in the future to select similar tradeoffs.

|
|
|
|
* ELF: --as-needed/--no-as-needed options to control if a DT_NEEDED tag should
|
|
|
|
|
be added only when a shared library is referenced.
|
2007-07-10 05:25:34 +08:00
|
|
|
|
|
2004-10-07 22:45:24 +08:00

|
|
|
* PE: --large-address-aware option to indicate executables support virtual
|

|
|
|
|
addresses greater than 2 gigabytes.

|
|
|
|
|
|
2004-04-21 18:04:02 +08:00
|
|
|
|
* The linker script operator DEFINED() will now yield 1 only for a symbol that
|
|
|
|
|
is defined before the statement where DEFINED is used.
|
|
|
|
|
|
2004-04-21 08:44:36 +08:00
|
|
|
|
* The MIPS --embedded-relocs (used to embed relocations into binaries for
|
|
|
|
|
Embedded-PIC code) is deprecated and will be removed in a future release.
|
|
|
|
|
|
2004-03-30 22:04:32 +08:00
|
|
|
|
* cr16c support added by NSC.

2003-12-19 19:44:01 +08:00
|
|
|
|
* m32r Linux (ELF) support added by Renesas.
|
|
|
|
|
|
2003-08-20 16:37:19 +08:00
|
|
|
|
* Improved linker's handling of unresolved symbols. The switch
|
|
|
|
|
--unresolved-symbols=<method> has been added to tell the linker when it
|
|
|
|
|
should report them and the switch --warn-unresolved-symbols has been added to
|
|
|
|
|
make reports be issued as warning messages rather than errors.

Changes in 2.14:
|
|
|
|
|
|
2003-04-03 15:37:41 +08:00
|
|
|
|
* Added support for Xtensa architecture.
|
|
|
|
|
|
2003-01-07 00:14:01 +08:00
|
|
|
|
* Added --with-sysroot configure switch to specify a target system root, for
|
|
|
|
|
linking against a target filesystem image.
|
|
|
|
|
|
2002-12-23 18:45:03 +08:00
|
|
|
|
* Added --accept-unknown-linker-format to restore old linker behaviour (pre
|
|
|
|
|
2.14) of silently accepting and linking in any files in an unknown binary
|
|
|
|
|
file format.
|
|
|
|
|
|
2002-10-23 21:24:10 +08:00
|
|
|
|
* Added --no-omagic to undo the effects of the -N option.
|
|
|
|
|
|
2002-09-11 22:42:45 +08:00
|
|
|
|
* Support for Texas Instruments TMS320C4x and TMS320C3x series of
|
|
|
|
|
DSP's contributed by Michael Hayes and Svein E. Seldal.
|
2007-07-10 05:25:34 +08:00
|
|
|
|
|
2002-08-23 16:03:32 +08:00
|
|
|
|
* Added --with-lib-path configure switch to specify default value for
|
|
|
|
|
LIB_PATH.
|
|
|
|
|
|
2002-07-31 01:32:30 +08:00
|
|
|
|
* ARM port to QNX operating system added by Graeme Peterson.
|
|
|
|
|
|
2002-07-17 22:15:52 +08:00
|
|
|
|
* IP2K support added by Denis Chertykov.
|
|
|
|
|
|
2002-07-16 15:58:34 +08:00
|
|
|
|
Changes in 2.13:
|
|
|
|
|
|
|
|
|
|
* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
|
|
|
|
|
and FR500 included.
|
2002-06-19 05:17:27 +08:00
|
|
|
|
|
2002-05-30 10:58:04 +08:00
|
|
|
|
Changes in version 2.13:
|
|
|
|
|
|
|
|
|
|
* DEC VAX ELF support, by Matt Thomas.
|
|
|
|
|
|
2002-02-20 18:46:54 +08:00
|
|
|
|
Changes in version 2.12:
|
|
|
|
|
|
2002-02-15 12:04:03 +08:00
|
|
|
|
* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
|
|
|
|
|
|
2002-02-01 01:33:08 +08:00
|
|
|
|
* Support for the OpenRISC 32-bit embedded processor by OpenCores.
|
|
|
|
|
|
2001-10-03 23:11:48 +08:00
|
|
|
|
* Support for -z nocopyreloc in the x86 ELF linker, which disables
|
|
|
|
|
production of copy relocs. Warning: using this option may result in
|
|
|
|
|
non-sharable applications.
|
2000-09-06 08:13:34 +08:00
|
|
|
|
|
2001-08-23 23:14:18 +08:00
|
|
|
|
* Support for -z combreloc in the ELF linker, which puts dynamic
|
|
|
|
|
relocations against the same symbol together, so that dynamic linker
|
|
|
|
|
can use an one-entry symbol lookup cache.
|
|
|
|
|
|
|
|
|
|
* Support for ELF SHF_MERGE section merging, by Jakub Jelinek.
|
|
|
|
|
|
2002-02-20 18:46:54 +08:00
|
|
|
|
Changes in version 2.11:
|
|
|
|
|
|
2000-12-11 21:49:46 +08:00
|
|
|
|
* Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
|
|
|
|
|
|
2000-09-03 05:35:47 +08:00
|
|
|
|
* Support added for eliminating duplicate DWARF2 debug information by
|
|
|
|
|
having the compiler generate the information in sections called
|
|
|
|
|
.gnu.linkonce.wi.XXXX where XXXX is a checksum for the contents. The
|
|
|
|
|
linker then merges these sections together into the normal .debug_info
|
|
|
|
|
section.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2000-08-23 03:34:37 +08:00
|
|
|
|
* The native ELF linker now searches the directories in DT_RUNPATH or
|
|
|
|
|
DT_RPATH of a shared library for shared libraries needed by it.
|
|
|
|
|
|
2000-06-20 21:31:59 +08:00
|
|
|
|
* TI C54x support, by Timothy Wall.
|
|
|
|
|
|
2000-05-23 05:58:40 +08:00
|
|
|
|
* Added command line switch --section-start to set the start address of any
|
2007-07-10 05:25:34 +08:00
|
|
|
|
specified section.
|
2000-05-23 05:58:40 +08:00
|
|
|
|
|
2000-05-18 03:38:53 +08:00
|
|
|
|
* Added ability to emit full relocation information in linked executables,
|
|
|
|
|
enabled by --emit-relocs. Some post-linkage optimization tools need
|
|
|
|
|
this information in order to be able to correctly identify and perform
|
|
|
|
|
symbol relative addressing in the event of changes in section contents
|
|
|
|
|
(instructions being added or deleted, extending data sections, etc.)
|
|
|
|
|
|
2000-08-15 02:50:13 +08:00
|
|
|
|
* Support for i860, by Jason Eckhardt (preliminary, alpha quality).
|
|
|
|
|
|
2000-08-25 01:42:52 +08:00
|
|
|
|
* Support for CRIS (Axis Communications ETRAX series).
|
|
|
|
|
|
2002-07-31 17:59:03 +08:00
|
|
|
|
* Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
|
|
|
|
|
|
2000-06-19 10:36:45 +08:00
|
|
|
|
Changes in version 2.10:
|
|
|
|
|
|
2007-07-10 05:25:34 +08:00
|
|
|
|
* Added AT> to the linker script language to allow load-time allocation of
|
2000-04-08 01:04:19 +08:00
|
|
|
|
sections into regions.
|
|
|
|
|
|
2007-07-10 05:25:34 +08:00
|
|
|
|
* Added garbage collection of unused sections, enabled by --gc-sections.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
It does require a bit of backend support; currently implemented are
|
2000-06-24 12:48:41 +08:00
|
|
|
|
arm-elf, avr-elf, d10v-elf, fr30-elf, i386-elf, m32r-elf, m68k-elf,
|
|
|
|
|
mcore-elf, mips-elf, mn10300-elf, ppc-elf, sh-elf, sparc-elf, and v850-elf.
|
2000-06-19 10:05:53 +08:00
|
|
|
|
Others will ignore the option.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
* Added SORT to the linker script language to permit sorting sections by file
|
|
|
|
|
name or section name.
|
|
|
|
|
|
|
|
|
|
* Added EXTERN to the linker script language as an equivalent to the -u
|
|
|
|
|
command-line option.
|
|
|
|
|
|
|
|
|
|
* Added ASSERT to the linker script language.
|
|
|
|
|
|
1999-06-13 18:20:50 +08:00
|
|
|
|
* Added EXCLUDE_FILE to the linker script language for further control over
|
|
|
|
|
wildcard file names.
|
|
|
|
|
|
1999-05-03 15:29:11 +08:00
|
|
|
|
* Added -O option to optimize linker output (as of this writing, this only
|
2002-07-31 17:59:03 +08:00
|
|
|
|
affects ELF shared library generation).
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
* The -e option now accepts a number as well as a symbol name.
|
|
|
|
|
|
1999-06-14 03:25:57 +08:00
|
|
|
|
* Added --no-undefined option to disallow undefined symbols when creating a
|
|
|
|
|
shared library.
|
|
|
|
|
|
2000-03-02 09:26:27 +08:00
|
|
|
|
* The linker now issues a warning, not an error, for an undefined symbol when
|
|
|
|
|
using -Bsymbolic; use the new --no-undefined option to get the old
|
|
|
|
|
behaviour.
|
|
|
|
|
|
1999-05-03 15:29:11 +08:00
|
|
|
|
* Added --demangle and --no-demangle options.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.9:
|
|
|
|
|
|
|
|
|
|
* Added SQUAD to the linker script language.
|
|
|
|
|
|
|
|
|
|
* New option --no-warn-mismatch.
|
|
|
|
|
|
|
|
|
|
* The MEMORY command now parses the attributes to determine where sections that
|
|
|
|
|
are not placed in a specific memory region are placed.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.8:
|
|
|
|
|
|
|
|
|
|
* Linker scripts may now contain shell wildcard characters for file and section
|
|
|
|
|
names.
|
|
|
|
|
|
|
|
|
|
* The linker now supports symbol versions in ELF.
|
|
|
|
|
|
|
|
|
|
* The NOCROSSREFS command was added to the linker script language.
|
|
|
|
|
|
|
|
|
|
* The LOADADDR expression was added to the linker script language.
|
|
|
|
|
|
|
|
|
|
* MAX and MIN functions were added to the linker script language.
|
|
|
|
|
|
|
|
|
|
* The OVERLAY construct was added to the linker script language.
|
|
|
|
|
|
|
|
|
|
* New option --warn-section-align to warn when the address of an output section
|
|
|
|
|
changes due to alignment of an input section.
|
|
|
|
|
|
|
|
|
|
* New options --filter/-F and --auxiliary/-f.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.7:
|
|
|
|
|
|
|
|
|
|
* New option --cref to print out a cross reference table.
|
|
|
|
|
|
|
|
|
|
* New option --wrap SYMBOL.
|
|
|
|
|
|
|
|
|
|
* New option --no-whole-archive, to turn off the effect of --whole-archive.
|
|
|
|
|
|
|
|
|
|
* Input sections assigned to the output section /DISCARD/ in the linker script
|
|
|
|
|
are not included in the output file.
|
|
|
|
|
|
|
|
|
|
* The SunOS and ELF linkers now merge stabs debugging information which uses
|
|
|
|
|
the N_BINCL and N_EINCL stab types. This reduces the amount of debugging
|
|
|
|
|
information generated.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.6:
|
|
|
|
|
|
|
|
|
|
* When an ELF section name is representable as a C identifier (this is not true
|
2008-05-21 20:16:22 +08:00
|
|
|
|
of most ELF section names), the linker will automatically define symbols
|
|
|
|
|
__start_SECNAME and __stop_SECNAME, where SECNAME is the section name, at the
|
|
|
|
|
beginning and the end of the section. This is used by glibc.
|
|
|
|
|
|
|
|
|
|
Addendum: Current versions of the linker (at least for version 2.18 onwards
|
|
|
|
|
and possibly much earlier as well) place two restrictions on this feature: The
|
|
|
|
|
symbols are only implemented for orphaned sections, not for explicitly placed
|
|
|
|
|
sections and they are PROVIDEd rather than being defined.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
* When an ELF section named .gnu.warning is encountered in an input file, the
|
|
|
|
|
contents of the section are displayed as an error message, and the section is
|
|
|
|
|
not copied into the output file. This is used by glibc.
|
|
|
|
|
|
|
|
|
|
* When an ELF section named .gnu.warning.SYMBOL is encountered in an input
|
|
|
|
|
file, and the symbol SYMBOL is referenced by some object file, the contents of
|
|
|
|
|
the section are displayed as an error message. The section is not copied into
|
2003-06-25 14:40:27 +08:00
|
|
|
|
the output file, unless doing a relocatable or shared link. This is used by
|
1999-05-03 15:29:11 +08:00
|
|
|
|
glibc.
|
|
|
|
|
|
|
|
|
|
* New options -split-by-reloc and -split-by-file.
|
|
|
|
|
|
|
|
|
|
* The linker now supports linking PIC compiled code on SPARC SunOS. It can
|
|
|
|
|
also create SPARC SunOS shared libraries, and, like the native SunOS linker,
|
|
|
|
|
will do so whenever there is an undefined symbol in the link and neither the -e
|
|
|
|
|
nor the -r option was used.
|
|
|
|
|
|
|
|
|
|
* The -rpath option may be used on SunOS to set the list of directories to be
|
|
|
|
|
searched at run time. This overrides the default of building the list from the
|
|
|
|
|
-L options.
|
|
|
|
|
|
|
|
|
|
* The COFF linker now combines debugging information for structs, unions, and
|
|
|
|
|
enums, so that even if the same type is defined in multiple input files it will
|
|
|
|
|
only be defined once in the output file. The --traditional-format switch will
|
|
|
|
|
prevent this optimization.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.5:
|
|
|
|
|
|
|
|
|
|
* The linker now supports linking against SunOS shared libraries. It still can
|
|
|
|
|
not link SunOS PIC (Position Independent Code) files, so it can not be used to
|
2003-10-26 00:26:30 +08:00
|
|
|
|
generate shared libraries.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
* The linker now supports linking against ELF shared libraries for the i386
|
|
|
|
|
(UnixWare) and SPARC (Solaris). It can also link ELF PIC files, and can be
|
|
|
|
|
used to generate shared libraries. Shared library generation is not well
|
|
|
|
|
tested; please report any problems encountered. The linker is now enabled for
|
|
|
|
|
Solaris again.
|
|
|
|
|
|
|
|
|
|
* Eric Youngdale has contributed Linux support code, including linking against
|
|
|
|
|
Linux a.out shared libraries. The linker produces Linux QMAGIC binaries.
|
|
|
|
|
|
|
|
|
|
* The ELF backend has been converted to the new linker code. To use the new
|
|
|
|
|
ELF linker, each particular target requires a relocation function. So far,
|
|
|
|
|
this function has been written for i386 (UnixWare), SPARC (Solaris) MIPS (Irix
|
|
|
|
|
5), and HPPA ELF targets.
|
|
|
|
|
|
|
|
|
|
* The -( (--start-group) and -) (--end-group) options have been added to
|
|
|
|
|
support searching a group of archives as though they were a single archive.
|
|
|
|
|
This can also be used in a linker script, as GROUP ( files ).
|
|
|
|
|
|
|
|
|
|
* When a file is named on the command line, and the linker does not recognize
|
|
|
|
|
it as an object file, the linker will now treat the file as a linker script
|
|
|
|
|
file. A linker script named in this way augments, but does not replace, the
|
|
|
|
|
default linker script.
|
|
|
|
|
|
|
|
|
|
* The -warn-once option was added. It causes the linker to only warn once per
|
|
|
|
|
undefined symbol, rather than once per reference.
|
|
|
|
|
|
|
|
|
|
* The COFF backend has been converted to the new linker code. As with ELF, to
|
|
|
|
|
use the new linker, each particular target requires a relocation function. So
|
|
|
|
|
far, this function has been written for the i386, m68k, a29k and SH targets.
|
|
|
|
|
|
|
|
|
|
* The -V flag was made a synonym for -v, for SVR4 compatibility. The old -V
|
|
|
|
|
behaviour is available via --verbose.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.4:
|
|
|
|
|
|
|
|
|
|
* New linker code, by Steve Chamberlain and Ian Taylor. For a.out and ecoff
|
|
|
|
|
formats (so far), this should result in considerable savings in time
|
|
|
|
|
and memory used while linking; slightly poorer performance than
|
|
|
|
|
before for formats not converted yet.
|
|
|
|
|
|
|
|
|
|
* Command-line parsing is no longer done with flex. This means
|
|
|
|
|
oddball characters in filenames won't get treated as argument
|
|
|
|
|
separators.
|
|
|
|
|
|
|
|
|
|
* HP-PA ELF support, by Jeff Law. (No SOM support yet.)
|
|
|
|
|
|
|
|
|
|
* Mach i386 support, by David Mackenzie.
|
|
|
|
|
|
|
|
|
|
* Irix 4 shared libraries are now supported (Irix 5 uses ELF, and ELF shared
|
|
|
|
|
libraries are not yet supported).
|
|
|
|
|
|
|
|
|
|
* COFF shared libraries (as on SCO) should work as well.
|
|
|
|
|
|
|
|
|
|
* The linker is disabled for Solaris. (Actually, it was in 2.3 also, I just
|
|
|
|
|
forgot to note it.) Some of their C library routines don't work when
|
|
|
|
|
statically linked, and the GNU linker doesn't support dynamic linking yet.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.3:
|
|
|
|
|
|
|
|
|
|
* Weak symbols are now supported.
|
|
|
|
|
|
|
|
|
|
* ELF support has been added. The linker has been bootstrapped on
|
|
|
|
|
UnixWare and Solaris.
|
|
|
|
|
|
|
|
|
|
* Alpha OSF/1 support has been added (non dynamic linking only).
|
|
|
|
|
|
|
|
|
|
Changes in version 2.2:
|
|
|
|
|
|
|
|
|
|
* The `bfd' library has been updated to reduce a.out-format string
|
|
|
|
|
table size. The effect of this is that files linked from many input
|
|
|
|
|
files with duplicate symbols (`-g' debugging records, or identical
|
|
|
|
|
static symbols) should be much smaller.
|
|
|
|
|
|
|
|
|
|
Changes in version 2.1:
|
|
|
|
|
|
|
|
|
|
* The ld -ySYMBOL flag (to trace references to SYMBOL) is now implemented.
|
|
|
|
|
|
|
|
|
|
* There is now support for writing ECOFF files, so ld and the
|
|
|
|
|
other utilities should work on Risc/Ultrix and Irix.
