+* The linker script operator DEFINED() will now yield 1 only for a symbol that
+ is defined before the statement where DEFINED is used.
+
+* The MIPS --embedded-relocs (used to embed relocations into binaries for
+ Embedded-PIC code) is deprecated and will be removed in a future release.
+
+* cr16c support added by NSC.
+
+* m32r Linux (ELF) support added by Renesas.
+
+* 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:
+
+* 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
- ppc-elf, mips-elf, and mn10300-elf. Others will ignore the option.

+ 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 -O option to optimize linker output (as of this writing, this only

* The -e option now accepts a number as well as a symbol name.
* When an ELF section named .gnu.warning.SYMBOL is encountered in an input

the section are displayed as an error message. The section is not copied into

* New options -split-by-reloc and -split-by-file.
* 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
