-Changes since version 2.7:
+* Added support for Xtensa architecture.
+
+* Added --with-sysroot configure switch to specify a target system root, for
+ linking against a target filesystem image.
+
+* 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.
+
+* Added --no-omagic to undo the effects of the -N option.
+
+* Support for Texas Instruments TMS320C4x and TMS320C3x series of
+ DSP's contributed by Michael Hayes and Svein E. Seldal.
+
+* Added --with-lib-path configure switch to specify default value for
+ LIB_PATH.
+
+* ARM port to QNX operating system added by Graeme Peterson.
+
+* IP2K support 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 2.13:
+
+* DEC VAX ELF support, by Matt Thomas.
+
+Changes in version 2.12:
+
+* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
+
+* Support for the OpenRISC 32-bit embedded processor by OpenCores.
+
+* 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.
+
+* 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.
+
+Changes in version 2.11:
+
+* Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
+
+* 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.
+
+* The native ELF linker now searches the directories in DT_RUNPATH or
+ DT_RPATH of a shared library for shared libraries needed by it.
+
+* TI C54x support, by Timothy Wall.
+
+* Added command line switch --section-start to set the start address of any
+ specified section.
+
+* 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.)
+
+* Support for i860, by Jason Eckhardt (preliminary, alpha quality).
+
+* Support for CRIS (Axis Communications ETRAX series).
+
+* Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
+
+Changes in version 2.10:
+
+* Added AT> to the linker script language to allow load-time allocation of
+ sections into regions.
+
+* Added garbage collection of unused sections, enabled by --gc-sections.
+ It does require a bit of backend support; currently implemented are
+ 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.
+ Others will ignore the option.
+
+* 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.
+
+* Added EXCLUDE_FILE to the linker script language for further control over
+ wildcard file names.
+
+* Added -O option to optimize linker output (as of this writing, this only
+ affects ELF shared library generation).
+
+* The -e option now accepts a number as well as a symbol name.
+
+* Added --no-undefined option to disallow undefined symbols when creating a
+ shared library.
+
+* 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.
+
+* 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.
-Changes since version 2.6:
+* 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.
the N_BINCL and N_EINCL stab types. This reduces the amount of debugging
information generated.
-Changes since version 2.5:
+Changes in version 2.6:
* When an ELF section name is representable as a C identifier (this is not true
of most ELF section names), the linker will automatically define symbols
only be defined once in the output file. The --traditional-format switch will
prevent this optimization.
-Changes since version 2.4:
+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
* The -V flag was made a synonym for -v, for SVR4 compatibility. The old -V
behaviour is available via --verbose.
-Changes since version 2.3:
+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
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 since version 2.2:
+Changes in version 2.3:
* Weak symbols are now supported.
* Alpha OSF/1 support has been added (non dynamic linking only).
-Changes since version 2.1:
+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 since version 2.0:
+Changes in version 2.1:
* The ld -ySYMBOL flag (to trace references to SYMBOL) is now implemented.
