Introduction
============
This document contains the release notes for the lld linker, release 8.0.0.
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/>`_.
lld is a high-performance linker that supports ELF (Unix), COFF (Windows),
Mach-O (macOS), MinGW and WebAssembly. lld is command-line-compatible with
GNU linkers and Microsoft link.exe and is significantly faster than the
system default linkers.
nlld 8.0.0 has lots of feature improvements and bug fixes.
Non-comprehensive list of changes in this release
=================================================
@ -33,27 +35,66 @@ ELF Improvements
non-superpages to a superpage if they are aligned to the superpage
size. (`r342746 <https://reviews.llvm.org/rL342746>`_)
* lld now attempts to place a ``.note`` segment in the first page of a
generated file, so that you can find some important information
(``.note.gnu.build-id`` in particular) in a core file even if a core
file is truncated by ulimit.
(`r349524 <https://reviews.llvm.org/rL349524>`_)
* lld now reports an error if ``_GLOBAL_OFFSET_TABLE_`` symbol is
defined by an input object file, as the symbol is supposed to be
synthesized by the linker.
(`r347854 <https://reviews.llvm.org/rL347854>`_)
* lld/Hexagon can now link Linux kernel and musl libc for Qualcomm
Hexagon ISA.
* Initial MSP430 ISA support has landed.
* The following flags have been added: ``-z interpose``, ``-z global``
* lld now uses the ``sigrie`` instruction as a trap instruction for
MIPS targets.
* lld now creates a TLS segment for AArch64 with a slightly larger
alignment requirement, so that the loader makes a few bytes room
before each TLS segment at runtime. The aim of this change is to
make room to accomodate nonstandard Android TLS slots while keeping
the compatibility with the standard AArch64 ABI.
(`r350681 <https://reviews.llvm.org/rL350681>`_)
* The following flags have been added: ``--call-graph-profile``,
``--no-call-graph-profile``, ``--warn-ifunc-textrel``,
``-z interpose``, ``-z global``, ``-z nodefaultlib``
COFF Improvements
-----------------
* PDB GUID is set to hash of PDB contents instead to a random byte
sequence for build reproducibility.
* ``/pdbsourcepath:`` is now also used to make ``"cwd"``, ``"exe"``, ``"pdb"``
in the env block of PDB outputs absolute if they are relative, and to make
paths to obj files referenced in PDB outputs absolute if they are relative.
Together with the previous item, this makes it possible to generate
executables and PDBs that are fully deterministic and independent of the
absolute path to the build directory, so that different machines building
the same code in different directories can produce exactly the same output.
* The following flags have been added: ``/force:multiple``
* lld now can link against import libraries produced by GNU tools.
* lld can create thunks for ARM, to allow linking images over 16 MB.
* lld can create thunks for ARM and ARM64, to allow linking larger images
(over 16 MB for ARM and over 128 MB for ARM64)
* Several speed and memory usage improvements.
* lld now creates debug info for typedefs.
* lld can now link obj files produced by ``cl.exe /Z7 /Yc``.
* lld now understands ``%_PDB%`` and ``%_EXT%`` in ``/pdbaltpath:``.
* Undefined symbols are now printed in demangled form in addition to raw form.
