Windows support
|
|
===============
|
|
|
|
LLD supports Windows operating system. When invoked as ``lld-link.exe`` or with
|
|
``-flavor link``, the driver for Windows operating system is used to parse
|
|
command line options, and it drives further linking processes. LLD accepts
|
|
almost all command line options that the linker shipped with Microsoft Visual
|
|
C++ (link.exe) supports.
|
|
|
|
The current status is that LLD can link itself on Windows x86/x64
|
|
using Visual C++ 2013 as the compiler.
|
|
|
|
Development status
|
|
==================
|
|
|
|
Driver
|
|
:good:`Mostly done`. Some exotic command line options that are not usually
|
|
used for application develompent, such as ``/DRIVER``, are not supported.
|
|
|
|
Linking against DLL
|
|
:good:`Done`. LLD can read import libraries needed to link against DLL. Both
|
|
export-by-name and export-by-ordinal are supported.
|
|
|
|
Linking against static library
|
|
:good:`Done`. The format of static library (.lib) on Windows is actually the
|
|
same as on Unix (.a). LLD can read it.
|
|
|
|
Creating DLL
|
|
:good:`Done`. LLD creates a DLL if ``/DLL`` option is given. Exported
|
|
functions can be specified either via command line (``/EXPORT``) or via
|
|
module-definition file (.def). Both export-by-name and export-by-ordinal are
|
|
supported.
|
|
|
|
Windows resource files support
|
|
:good:`Done`. If an ``.res`` file is given, LLD converts the file to a COFF
|
|
file using LLVM's Object library.
|
|
|
|
Safe Structured Exception Handler (SEH)
|
|
:good:`Done` for both x86 and x64.
|
|
|
|
Module-definition file
|
|
:partial:`Partially done`. LLD currently recognizes these directives:
|
|
``EXPORTS``, ``HEAPSIZE``, ``STACKSIZE``, ``NAME``, and ``VERSION``.
|
|
|
|
Debug info
|
|
:none:`No progress has been made`. Microsoft linker can interpret the CodeGen
|
|
debug info (old-style debug info) and PDB to emit an .pdb file. LLD doesn't
|
|
support neither.
|
|
|
|
|
|
Building LLD
|
|
============
|
|
|
|
Using Visual Studio IDE/MSBuild
|
|
-------------------------------
|
|
|
|
1. Check out LLVM and LLD from the LLVM SVN repository (or Git mirror),
|
|
#. run ``cmake -G "Visual Studio 12" <llvm-source-dir>`` from VS command prompt,
|
|
#. open LLVM.sln with Visual Studio, and
|
|
#. build ``lld`` target in ``lld executables`` folder
|
|
|
|
Alternatively, you can use msbuild if you don't like to work in an IDE::
|
|
|
|
msbuild LLVM.sln /m /target:"lld executables\lld"
|
|
|
|
MSBuild.exe had been shipped as a component of the .NET framework, but since
|
|
2013 it's part of Visual Studio. You can find it at "C:\\Program Files
|
|
(x86)\\msbuild".
|
|
|
|
You can build LLD as a 64 bit application. To do that, open VS2013 x64 command
|
|
prompt and run cmake for "Visual Studio 12 Win64" target.
|
|
|
|
Using Ninja
|
|
-----------
|
|
|
|
1. Check out LLVM and LLD from the LLVM SVN repository (or Git mirror),
|
|
#. run ``cmake -G ninja <llvm-source-dir>`` from VS command prompt,
|
|
#. run ``ninja lld``
|
