lld - The LLVM Linker
|
|
=====================
|
|
|
|
lld is a new set of modular code for creating linker tools.
|
|
|
|
* End-User Features:
|
|
|
|
* Compatible with existing linker options
|
|
* Reads standard Object Files (e.g. ELF, Mach-O, PE/COFF)
|
|
* Writes standard Executable Files (e.g. ELF, Mach-O, PE)
|
|
* Fast link times
|
|
* Minimal memory use
|
|
* Remove clang's reliance on "the system linker"
|
|
* Uses the LLVM `"UIUC" BSD-Style license`__.
|
|
|
|
* Applications:
|
|
|
|
* Modular design
|
|
* Support cross linking
|
|
* Easy to add new CPU support
|
|
* Can be built as static tool or library
|
|
|
|
* Design and Implementation:
|
|
|
|
* Extensive unit tests
|
|
* Internal linker model can be dumped/read to textual format
|
|
* Internal linker model can be dumped/read to a new native format
|
|
* Native format designed to be fast to read and write
|
|
* Additional linking features can be plugged in as "passes"
|
|
* OS specific and CPU specific code factored out
|
|
|
|
Why a new linker?
|
|
-----------------
|
|
|
|
The fact that clang relies on whatever linker tool you happen to have installed
|
|
means that clang has been very conservative adopting features which require a
|
|
recent linker.
|
|
|
|
In the same way that the MC layer of LLVM has removed clang's reliance on the
|
|
system assembler tool, the lld project will remove clang's reliance on the
|
|
system linker tool.
|
|
|
|
|
|
Current Status
|
|
--------------
|
|
|
|
lld can self host on x86-64 FreeBSD and Linux and x86 Windows.
|
|
|
|
All SingleSource tests in test-suite pass on x86-64 Linux.
|
|
|
|
All SingleSource and MultiSource tests in the LLVM test-suite
|
|
pass on MIPS 32-bit little-endian Linux.
|
|
|
|
Source
|
|
------
|
|
|
|
lld is available in the LLVM SVN repository::
|
|
|
|
svn co http://llvm.org/svn/llvm-project/lld/trunk lld
|
|
|
|
lld is also available via the read-only git mirror::
|
|
|
|
git clone http://llvm.org/git/lld.git
|
|
|
|
Put it in llvm's tools/ directory, rerun cmake, then build target lld.
