<p>This document provides <em>usage</em> information about the LLVM makefile
|
|
|
|
|
system. While loosely patterned after the BSD makefile system, LLVM has taken
|
2004-10-25 19:28:03 +00:00
|
|
|
a departure from BSD in order to implement additional features needed by LLVM.
|
2004-10-31 17:51:38 +00:00
|
|
|
Although makefile systems such as automake were attempted at one point, it
|
|
|
|
|
has become clear that the features needed by LLVM and the Makefile norm are
|
|
|
|
|
too great to use a more limited tool. Consequently, LLVM requires simply GNU
|
|
|
|
|
Make 3.79, a widely portable makefile processor. LLVM unabashedly makes heavy
|
|
|
|
|
use of the features of GNU Make so the dependency on GNU Make is firm. If
|
|
|
|
|
you're not familiar with <tt>make</tt>, it is recommended that you read the
|
|
|
|
|
<a href="http://www.gnu.org/software/make/manual/make.html">GNU Makefile Manual
|
|
|
|
|
</a>.</p>

<p>While this document is rightly part of the
|
|
|
|
|
<a href="ProgrammersManual.html">LLVM Programmer's Manual</a>, it is treated
|
|
|
|
|
separately here because of the volume of content and because it is often an
|
|
|
|
|
early source of bewilderment for new developers.</p>

<p>The LLVM Makefile System is the component of LLVM that is responsible for
|
|
|
|
|
building the software, testing it, generating distributions, checking those
|
|
|
|
|
distributions, installing and uninstalling, etc. It consists of a several
|
|
|
|
|
files throughout the source tree. These files and other general concepts are
|
|
|
|
|
described in this section.</p>

<p>The LLVM Makefile System is quite generous. It not only builds its own
|
|
|
|
|
software, but it can build yours too. Built into the system is knowledge of
|
|
|
|
|
the <tt>llvm/projects</tt> directory. Any directory under <tt>projects</tt>
|
|
|
|
|
that has both a <tt>configure</tt> script and a <tt>Makefile</tt> is assumed
|
|
|
|
|
to be a project that uses the LLVM Makefile system. This allows your project
|
|
|
|
|
to get up and running quickly by utilizing the built-in features that are used
|
2004-10-31 17:51:38 +00:00
|
|
|
to compile LLVM. LLVM compiles itself using the same features of the makefile
|
|
|
|
|
system as used for projects.</p>

<p>To use the makefile system, you simply create a file named
|
|
|
|
|
<tt>Makefile</tt> in your directory and declare values for certain variables.
|
|
|
|
|
The variables and values that you select determine what the makefile system
|
|
|
|
|
will do. These variables enable rules and processing in the makefile system
|

|
that automatically Do The Right Thing™.

<p>This section provides some examples of the different kinds of modules you

|
|
|
|
can build with the LLVM makefile system. In general, each directory you
|
|
|
|

provide will build a single object although that object may be composed of
|
|
|
|
|
additionally compiled components.</p>

<div class="doc_text">
|
|
|
|
|
<p>Only a few variable definitions are needed to build a regular library.
|
|
|
|
|
Normally, the makefile system will build all the software into a single
|
|
|
|
|
<tt>libname.o</tt> (pre-linked) object. This means the library is not
|
|
|
|
|
searchable and that the distinction between compilation units has been
|
|
|
|
|
dissolved. Optionally, you can ask for a shared library (.so), archive library
|
|
|
|
|
(.a) or to not have the default (relinked) library built. For example:</p>
|
|
|
|
|
<pre><tt>
|
|
|
|
|
LIBRARYNAME = mylib
|
|
|
|
|
SHARED_LIBRARY = 1
|
|
|
|
|
ARCHIVE_LIBRARY = 1
|
|
|
|
|
DONT_BUILT_RELINKED = 1
|
|
|
|
|
</tt></pre>
|
|
|
|
|
<p>says to build a library named "mylib" with both a shared library
|
|
|
|
|
(<tt>mylib.so</tt>) and an archive library (<tt>mylib.a</tt>) version but
|
|
|
|
|
not to build the relinked object (<tt>mylib.o</tt>). The contents of all the
|
|
|
|
|
libraries produced will be the same, they are just constructed differently.
|
|
|
|
|
Note that you normally do not need to specify the sources involved. The LLVM
|
|
|
|
|
Makefile system will infer the source files from the contents of the source
|
|
|
|
|
directory.</p>

|
<p>For building executable programs (tools), you must provide the name of the
|
|
|
|
|
tool and the names of the libraries you wish to link with the tool. For
|
|
|
|
|
example:</p>
|
|

<pre><tt>

TOOLNAME = mytool

USEDLIBS = mylib

LLVMLIBS = LLVMSupport.a LLVMSystem.a

</tt></pre>
|
|
|
|
|
<p>says that we are to build a tool name <tt>mytool</tt> and that it requires
|
|
|
|
|
three libraries: <tt>mylib</tt>, <tt>LLVMSupport.a</tt> and
|
|
|
|
|
<tt>LLVMSystem.a</tt>.</p>
|
|
|
|
|
<p>Note that two different variables are use to indicate which libraries are
|
|
|
|
|
linked: <tt>USEDLIBS</tt> and <tt>LLVMLIBS</tt>. This distinction is necessary
|
|
|
|
|
to support projects. <tt>LLVMLIBS</tt> refers to the LLVM libraries found in
|
|
|
|
|
the LLVM object directory. <tt>USEDLIBS</tt> refers to the libraries built by
|
|
|
|
|
your project. In the case of building LLVM tools, <tt>USEDLIBS</tt> and
|
|
|
|
|
<tt>LLVMLIBS</tt> can be used interchangeably since the "project" is LLVM
|
|
|
|
|
itself and <tt>USEDLIBS</tt> refers to the same place as <tt>LLVMLIBS</tt>.
|
|
|
|
|
</p>
|
|
|
|
|
<p>Also note that there are two different ways of specifying a library: with a
|
|
|
|
|
<tt>.a</tt> suffix and without. Without the suffix, the entry refers to the
|
|
|
|
|
re-linked (.o) file which will include <em>all</em> symbols of the library.

|
|
|
|
This is useful, for example, to include all passes from a library of passes.
|
|
|
|
|
If the <tt>.a</tt> suffix is used then the library is linked as a searchable
|
|
|
|
|
library (with the <tt>-l</tt> option). In this case, only the symbols that are
|
|
|
|
|
unresolved <em>at that point</em> will be resolved from the library, if they
|
|
|
|
|
exist. Other (unreferenced) symbols will not be included when the <tt>.a</tt>
|
|
|
|
|
syntax is used. Note that in order to use the <tt>.a</tt> suffix, the library
|
|
|
|
|
in question must have been built with the <tt>ARCHIVE_LIBRARY</tt> option set.

<p>This target is used to perform any functional, unit or sanity tests as the

|
|
|
|
software is being built. The <tt>check</tt> target depends on the
|
|
|
|

<a href="#all"><tt>all</tt></a> target so the software is built in each
|
|
|
|
|
directory first and then the "check" is applied.</p>
|
|
|
|
|
<p>The definition of "check" is pretty general. It depends on the value of the
|
|
|
|
|
<a href="#TESTS"><tt>TESTS</tt></a> variable. This variable should be set to a
|
|
|
|
|
list of executables to run in order to test the software. If they all return
|
|
|
|
|
0 then the check succeeds, otherwise not. The programs run can be anything but
|
|
|
|
|
they should either be local to the directory or in your path.</p>
