This was removed from the ABI in riscv-non-isa/riscv-elf-psabi-doc#398.
It is not emitted by LLVM, and seems to have been an internal
implementation detail in binutils.
This is a follow-up to 26ec5da744 which removed previous binutils
internal relocations when they were removed from the ABI.
The LLD implementation was not tested when it was added in

Introduction
|
|
============
|
|
|
|
This document contains the release notes for the lld linker, release |release|.
|
|
Here we describe the status of lld, including major improvements
|
|
from the previous release. All lld releases may be downloaded
|
|
from the `LLVM releases web site <https://llvm.org/releases/>`_.

Non-comprehensive list of changes in this release
|
|
=================================================
|
|
|
|
ELF Improvements
|
|
----------------
|
|
|
|
* ``-z nosectionheader`` has been implemented to omit the section header table.
|
|
The operation is similar to ``llvm-objcopy --strip-sections``.
|
|
(`#101286 <https://github.com/llvm/llvm-project/pull/101286>`_)
|
|
* Section ``CLASS`` linker script syntax binds input sections to named classes,
|
|
which are referenced later one or more times. This provides access to the
|
|
automatic spilling mechanism of `--enable-non-contiguous-regions` without
|
|
globally changing the semantics of section matching. It also independently
|
|
increases the expressive power of linker scripts.
|
|
(`#95323 <https://github.com/llvm/llvm-project/pull/95323>`_)
|
|
|
|
Breaking changes
|
|
----------------
|
|
|
|
* Removed support for the (deprecated) `R_RISCV_RVC_LUI` relocation. This
|
|
was a binutils-internal relocation used during relaxation, and was not
|
|
emitted by compilers/assemblers.
|
|
|
|
COFF Improvements
|
|
-----------------
|
|
* ``/includeglob`` has been implemented to match the behavior of ``--undefined-glob`` available for ELF.
|
|
* ``/lldsavetemps`` allows saving select intermediate LTO compilation results (e.g. resolution, preopt, promote, internalize, import, opt, precodegen, prelink, combinedindex).
|
|
* ``/machine:arm64ec`` support completed, enabling the linking of ARM64EC images.
|
|
* COFF weak anti-dependency alias symbols are now supported.
|
|
|
|
MinGW Improvements
|
|
------------------
|
|
* ``--undefined-glob`` is now supported by translating into the ``/includeglob`` flag.
|
|
