+
+* ELF: --warn-alternate-em option to warn if an object has alternate
+ ELF machine code.
+
+* New script function REGION_ALIAS to add alias names to memory regions.
+
+* 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
+ 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.
+
+* --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.
+
+* Add a new command line option, -Ttext-segment ADDR, for ELF targets
+ to set the address of the first byte of the text segment.
+
+* Add support for Sunplus score architecture.
+
+* Add new option --use-nul-prefixed-import-tables to ld for PE targets to
+ allow fallback to old import table generation with null element prefix.
+
+* Windows PE systems now support a new --exclude-modules-for-implib option,
+ allowing users to partition object files and archive members between a DLL
+ and its associated import library as they are generated during linking.
+
+* Add support for Lattice Mico32 (lm32) architecture.
+
+* Add CR16 ELF --embedded-relocs (used to embedded relocations into binaries
+ for Embedded-PIC code) option.
+
+* Add to the PE/PE+ targets the support of two different kinds of
+ pseudo-relocations. They can be selected by the switches
+ --enable-runtime-pseudo-reloc-v1 and --enable-runtime-pseudo-reloc-v2.
+ For the switch --enable-runtime-pseudo-reloc it uses for 32-bit
+ runtime pseudo relocation version one, for 64-bit the version two.
+
+Changes in 2.19:
+
+* Linker scripts support a new INSERT command that makes it easier to
+ augment the default script.
+
+* Linker script input section filespecs may now specify a file within an
+ archive by writing "archive:file".
+
+* The --sort-common switch now has an optional argument which specifies the
+ direction of sorting.
+
+* The M68K linker now supports multiple GOT generation schemes controlled via
+ the --got=<type> command line option.
+
+* The ARM EABI linker will now generate stubs for function calls to symbols
+ that are too far away. The placement of the stubs is controlled by a new
+ linker command line option: --stub-group-size=N.
+
+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.
* 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.
* 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.
* 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

sections into regions.
-* Added garbage collection of unused sections, enabled by --gc-sections.

__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.
+
* 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.
