<p>Amongst other things, LLVM is a toolkit for building compilers, linkers,
|
|
runtime executives, virtual machines, and other program execution related
|
|
tools. In addition to the LLVM tool set, the functionality of LLVM is
|
|
available through a set of libraries. To use LLVM as a toolkit for
|
|
constructing tools, a developer needs to understand what is contained in the
|
|
various libraries, what they depend on, and how to use them. Fortunately,
|
|
there is a tool, <tt>llvm-config</tt> to aid with this. This document
|
|
describes the contents of the libraries and how to use <tt>llvm-config</tt>
|
|
to generate command line options.
|

<div class="doc_text">
|
|
<p>If you're writing a compiler, virtual machine, or any other utility based
|
|
on LLVM, you'll need to figure out which of the many libraries files you will
|
|
need to link with to be successful. An understanding of the contents of these
|
|
libraries will be useful in coming up with an optimal specification for the
|
|
libraries to link with. The purpose of this document is to reduce some of
|
|
the trial and error that the author experienced in using LLVM.</p>
|
|
<p>LLVM produces two types of libraries: archives (ending in <tt>.a</tt>) and
|
|
objects (ending in <tt>.o</tt>). However, both are libraries. Libraries ending
|
|
in <tt>.o</tt> are known as re-linked libraries because they contain all the
|
|
compilation units of the library linked together as a single <tt>.o</tt> file.
|
|
Furthermore, several of the libraries have <em>both</em> forms of library. The
|
|
re-linked libraries are used whenever you want to include all symbols from the
|
|
library. The archive libraries are used whenever you want to only resolve
|
|
outstanding symbols at that point in the link without including everything in
|
|
the library. </p>
|
|
<p>If you're using the LLVM Makefile system to link your tools,you will use
|
|
the <tt>LLVMLIBS</tt> make variable.
|
|
(see the <a href="MakefileGuide.html#LLVMLIBS">Makefile Guide</a> for
|
|
details). This variable specifies which LLVM libraries to link into your tool
|
|
and the order in which they will be linked. You specify re-linked libraries by
|
|
naming the library without a suffix. You specify archive libraries by naming
|
|
the library with a <tt>.a</tt> suffix but without the <tt>lib</tt> prefix. The
|
|
order in which the libraries appear in the <tt>LLVMLIBS</tt> variable
|
|
definition is the order in which they will be linked. Getting this order
|
|
correct for your tool can sometimes be challenging.

<div class="doc_text">
|
|
<p>The <tt>llvm-config</tt> tool is a perl script that produces on its output
|
|
various kinds of information. For example, the source or object directories
|
|
used to build LLVM can be accessed by passing options to <tt>llvm-config</tt>.
|
|
For complete details on this tool, please see the
|
|
<a href="CommandGuide/html/llvm-config.html">manual page</a>.</p>
|
|
<p>To understand the relationships between libraries, the <tt>llvm-config</tt>
|
|
can be very useful. If all you know is that you want certain libraries to
|
|
be available, you can generate the complete set of libraries to link with
|
|
using one of four options, as below:</p>
|
|
<ol>
|
|
<li><tt>--ldflags</tt>. This generates the command line options necessary to
|
|
be passed to the <tt>ld</tt> tool in order to link with LLVM. Most notably,
|
|
the <tt>-L</tt> option is provided to specify a library search directory
|
|
that contains the LLVM libraries.</li>
|
|
<li><tt>--libs</tt>. This generates command line options suitable for
|
|
use with a gcc-style linker. That is, libraries are given with a -l option
|
|
and object files are given with a full path.</li>
|
|
<li><tt>--libnames</tt>. This generates a list of just the library file
|
|
names. If you know the directory in which these files reside (see --ldflags)
|
|
then you can find the libraries there.</li>
|
|
<li><tt>--libfiles</tt>. This generates the full path names of the
|
|
LLVM library files.</li>
|
|
</ol>
|
|
<p>If you wish to delve further into how <tt>llvm-config</tt> generates the
|
|
correct order (based on library dependencies), please see the tool named
|
|
<tt>GenLibDeps.pl</tt> in the <tt>utils</tt> source directory of LLVM.</p>
|
|
|
|
<!-- =======NOTE: =========================================================-->

<!-- === The following graphs and <dl> list are generated automatically ===-->

<h2>Dependency Relationships Of Libraries</h2>
|
|
<p>This graph shows the dependency of archive libraries on other archive
|
|
libraries or objects. Where a library has both archive and object forms, only
|
|
the archive form is shown.</p>

<h2>Dependency Relationships Of Object Files</h2>
|
|
<p>This graph shows the dependency of object files on archive libraries or

|
other objects. Where a library has both object and archive forms, only the

dependency to the archive form is shown.</p>

<img src="img/objdeps.gif" alt="Object File Dependencies"/>

<p>The following list shows the dependency relationships between libraries in

<p>No matter what you do with LLVM, the last three entries in the value of
|
|
your LLVMLIBS make variable should always be:
|

<tt>LLVMCore LLVMSupport.a LLVMSystem.a</tt>. There are no <tt>LLVM</tt>

<div class="doc_text">
|
|
<p>There is never any point to linking both the re-linked (<tt>.o</tt>) and
|
|
the archive (<tt>.a</tt>) versions of a library. Since the re-linked version
|
|
includes the entire library, the archive version will not resolve any symbols.
|
|
You could even end up with link error if you place the archive version before
|
|
the re-linked version on the linker's command line.</p>
