+Changes in 2.18:
+
+* Linker sources now released under version 3 of the GNU General Public
+ License.
+
+* ELF: New --build-id option to generate a unique per-binary identifier
+ embedded in a note section.
+
+* Added support for National Semicondutor CompactRISC (ie CR16) target.
+
+* -l:foo now searches the library path for a filename called foo,
+ without converting it to libfoo.a or libfoo.so.
+
+* Add a new command line option '--default-script=FILE' or '-dT FILE'
+ which specifies a replacement for the built in, default linker
+ script.
+
+* 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.
+
+* Add support for x86_64 PE+ target.
+
+* Add support for Score target.
+
+* 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.
+
+* 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.
+
+* New switch: --print-gc-sections to list any sections removed by garabge
+ collection.
+
+* ARM: Added --vfp11-denorm-fix option to work around an erratum in current
+ VFP11 coprocessors.
+
+Changes in 2.17:
+
+* Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
+
+* 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.
+
+* PE-COFF: Forward exports from DLL's can now be specified in .def files
+ passed directly to ld.
+
+* Support for the Z80 processor family has been added.
+
+* Add support for the "@<file>" syntax to the command line, so that extra
+ switches can be read from <file>.
+
+Changes in 2.16:
+
+* Support for the R_ARM_V4BX relocation as defined in the ARM AAELF
+ specification has been added via the --fix-v4bx command-line option.
+
+* New linker script construct AS_NEEDED(), which sets the --as-needed flag
+ for input files listed inside of it.
+
+* 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.
+
+* New linker script functions: ORIGIN() and LENGTH() which return information
+ about a specified memory region.
+
+* Port to MAXQ processor contributed by HCL Tech.
+
+* Added SEGMENT_START to the linker script language to permit the user to
+ override the base address for a segment from the command-line.
+
+* ELF: --warn-shared-textrel option to warn if adding a DT_TEXTREL to a shared
+ object.
* Added SORT_BY_NAME and SORT_BY_ALIGNMENT to the linker script
language to permit sorting sections by section name or section
* Added a new linker command line switch, --sort-section name|alignment,
to sort sections by section name or maximum alignment.
-* New 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.
+* 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.
* Support for the crx-elf target added.
Changes in 2.15:
-* New ELF --as-needed/--no-as-needed options to control if a DT_NEEDED
-tag should be added only when a shared library is referenced.
-
-* New PE --large-address-aware option to indicate executables support virtual
+* ELF: --as-needed/--no-as-needed options to control if a DT_NEEDED tag should
+ be added only when a shared library is referenced.
+
+* PE: --large-address-aware option to indicate executables support virtual
addresses greater than 2 gigabytes.
* DWARF 2 support for i386pe added.
* 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.
* TI C54x support, by Timothy Wall.
* Added command line switch --section-start to set the start address of any
- specified section.
+ specified section.
* Added ability to emit full relocation information in linked executables,
enabled by --emit-relocs. Some post-linkage optimization tools need
Changes in version 2.10:
-* Added AT> to the linker script language to allow load-time allocation of
+* 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.
