+<p>The Clang driver is intended to be a production quality compiler driver
+providing access to the Clang compiler and tools, with a command line

+<p>Although the driver is part of and driven by the Clang project, it is

+<h3><a class="toc-backref" href="#id18">GCC Compatibility</a><a class="headerlink" href="#gcc-compatibility" title="Permalink to this headline">¶</a></h3>
+<p>The number one goal of the driver is to ease the adoption of Clang by
+allowing users to drop Clang into a build system which was designed to
+call GCC. Although this makes the driver much more complicated than
+might otherwise be necessary, we decided that being very compatible with
+the gcc command line interface was worth it in order to allow users to
+quickly test clang on their projects.</p>
+</div>
+<div class="section" id="flexible">
+<h3><a class="toc-backref" href="#id19">Flexible</a><a class="headerlink" href="#flexible" title="Permalink to this headline">¶</a></h3>
+<p>The driver was designed to be flexible and easily accommodate new uses
+as we grow the clang and LLVM infrastructure. As one example, the driver
+can easily support the introduction of tools which have an integrated
+assembler; something we hope to add to LLVM in the future.</p>
+<p>Similarly, most of the driver functionality is kept in a library which
+can be used to build other tools which want to implement or accept a gcc
+like interface.</p>

+<div class="section" id="low-overhead">
+<h3><a class="toc-backref" href="#id20">Low Overhead</a><a class="headerlink" href="#low-overhead" title="Permalink to this headline">¶</a></h3>
+<p>The driver should have as little overhead as possible. In practice, we
+found that the gcc driver by itself incurred a small but meaningful
+overhead when compiling many small files. The driver doesn’t do much
+work compared to a compilation, but we have tried to keep it as
+efficient as possible by following a few simple principles:</p>
+<ul class="simple">
+<li>Avoid memory allocation and string copying when possible.</li>
+<li>Don’t parse arguments more than once.</li>
+<li>Provide a few simple interfaces for efficiently searching arguments.</li>

+<h3><a class="toc-backref" href="#id21">Simple</a><a class="headerlink" href="#simple" title="Permalink to this headline">¶</a></h3>
+<p>Finally, the driver was designed to be “as simple as possible”, given
+the other goals. Notably, trying to be completely compatible with the
+gcc driver adds a significant amount of complexity. However, the design
+of the driver attempts to mitigate this complexity by dividing the
+process into a number of independent stages instead of a single
+monolithic task.</p>

+<p>In order to satisfy the stated goals, the driver was designed to
+completely subsume the functionality of the gcc executable; that is, the
+driver should not need to delegate to gcc to perform subtasks. On
+Darwin, this implies that the Clang driver also subsumes the gcc
+driver-driver, which is used to implement support for building universal
+images (binaries and object files). This also implies that the driver
+should be able to call the language specific compilers (e.g. cc1)
+directly, which means that it must have enough information to forward
+command line arguments to child processes correctly.</p>

+<div class="section" id="driver-stages">
+<h3><a class="toc-backref" href="#id24">Driver Stages</a><a class="headerlink" href="#driver-stages" title="Permalink to this headline">¶</a></h3>
+<p>The driver functionality is conceptually divided into five stages:</p>
+<ol class="arabic">
+<li><p class="first"><strong>Parse: Option Parsing</strong></p>
+<p>The command line argument strings are decomposed into arguments
+(<tt class="docutils literal"><span class="pre">Arg</span></tt> instances). The driver expects to understand all available
+options, although there is some facility for just passing certain
+classes of options through (like <tt class="docutils literal"><span class="pre">-Wl,</span></tt>).</p>
+<p>Each argument corresponds to exactly one abstract <tt class="docutils literal"><span class="pre">Option</span></tt>
+definition, which describes how the option is parsed along with some
+additional metadata. The Arg instances themselves are lightweight and
+merely contain enough information for clients to determine which
+option they correspond to and their values (if they have additional
+parameters).</p>
+<p>For example, a command line like “-Ifoo -I foo” would parse to two
+Arg instances (a JoinedArg and a SeparateArg instance), but each
+would refer to the same Option.</p>
+<p>Options are lazily created in order to avoid populating all Option
+classes when the driver is loaded. Most of the driver code only needs
+to deal with options by their unique ID (e.g., <tt class="docutils literal"><span class="pre">options::OPT_I</span></tt>),</p>
+<p>Arg instances themselves do not generally store the values of
+parameters. In many cases, this would simply result in creating
+unnecessary string copies. Instead, Arg instances are always embedded
+inside an ArgList structure, which contains the original vector of
+argument strings. Each Arg itself only needs to contain an index into
+this vector instead of storing its values directly.</p>
+<p>The clang driver can dump the results of this stage using the
+<tt class="docutils literal"><span class="pre">-###</span></tt> flag (which must precede any actual command
+line arguments). For example:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> clang -### -Xarch_i386 -fomit-frame-pointer -Wa,-fast -Ifoo -I foo t.c
+<span class="go">Option 0 - Name: "-Xarch_", Values: {"i386", "-fomit-frame-pointer"}</span>
+<span class="go">Option 1 - Name: "-Wa,", Values: {"-fast"}</span>
+<span class="go">Option 2 - Name: "-I", Values: {"foo"}</span>
+<span class="go">Option 3 - Name: "-I", Values: {"foo"}</span>
+<span class="go">Option 4 - Name: "<input>", Values: {"t.c"}</span>
+</pre></div>
+</div>
+<p>After this stage is complete the command line should be broken down
+into well defined option objects with their appropriate parameters.
+Subsequent stages should rarely, if ever, need to do any string
+processing.</p>
+</li>
+<li><p class="first"><strong>Pipeline: Compilation Action Construction</strong></p>
+<p>Once the arguments are parsed, the tree of subprocess jobs needed for
+the desired compilation sequence are constructed. This involves
+determining the input files and their types, what work is to be done
+on them (preprocess, compile, assemble, link, etc.), and constructing
+a list of Action instances for each task. The result is a list of one
+or more top-level actions, each of which generally corresponds to a
+single output (for example, an object or linked executable).</p>
+<p>The majority of Actions correspond to actual tasks, however there are
+two special Actions. The first is InputAction, which simply serves to
+adapt an input argument for use as an input to other Actions. The
+second is BindArchAction, which conceptually alters the architecture
+to be used for all of its input Actions.</p>
+<p>The clang driver can dump the results of this stage using the
+<tt class="docutils literal"><span class="pre">-ccc-print-phases</span></tt> flag. For example:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> clang -ccc-print-phases -x c t.c -x assembler t.s
+<span class="go">0: input, "t.c", c</span>
+<span class="go">1: preprocessor, {0}, cpp-output</span>
+<span class="go">2: compiler, {1}, assembler</span>
+<span class="go">3: assembler, {2}, object</span>
+<span class="go">4: input, "t.s", assembler</span>
+<span class="go">5: assembler, {4}, object</span>
+<span class="go">6: linker, {3, 5}, image</span>
+</pre></div>
+</div>
+<p>Here the driver is constructing seven distinct actions, four to
+compile the “t.c” input into an object file, two to assemble the
+“t.s” input, and one to link them together.</p>
+<p>A rather different compilation pipeline is shown here; in this
+example there are two top level actions to compile the input files
+into two separate object files, where each object file is built using
+<tt class="docutils literal"><span class="pre">lipo</span></tt> to merge results built for two separate architectures.</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> clang -ccc-print-phases -c -arch i386 -arch x86_64 t0.c t1.c
+<span class="go">0: input, "t0.c", c</span>
+<span class="go">1: preprocessor, {0}, cpp-output</span>
+<span class="go">2: compiler, {1}, assembler</span>
+<span class="go">3: assembler, {2}, object</span>
+<span class="go">4: bind-arch, "i386", {3}, object</span>
+<span class="go">5: bind-arch, "x86_64", {3}, object</span>
+<span class="go">6: lipo, {4, 5}, object</span>
+<span class="go">7: input, "t1.c", c</span>
+<span class="go">8: preprocessor, {7}, cpp-output</span>
+<span class="go">9: compiler, {8}, assembler</span>
+<span class="go">10: assembler, {9}, object</span>
+<span class="go">11: bind-arch, "i386", {10}, object</span>
+<span class="go">12: bind-arch, "x86_64", {10}, object</span>
+<span class="go">13: lipo, {11, 12}, object</span>
+</pre></div>
+</div>
+<p>After this stage is complete the compilation process is divided into
+a simple set of actions which need to be performed to produce
+intermediate or final outputs (in some cases, like <tt class="docutils literal"><span class="pre">-fsyntax-only</span></tt>,
+there is no “real” final output). Phases are well known compilation
+steps, such as “preprocess”, “compile”, “assemble”, “link”, etc.</p>
+</li>
+<li><p class="first"><strong>Bind: Tool & Filename Selection</strong></p>
+<p>This stage (in conjunction with the Translate stage) turns the tree
+of Actions into a list of actual subprocess to run. Conceptually, the
+driver performs a top down matching to assign Action(s) to Tools. The
+ToolChain is responsible for selecting the tool to perform a
+particular action; once selected the driver interacts with the tool
+to see if it can match additional actions (for example, by having an
+integrated preprocessor).</p>
+<p>Once Tools have been selected for all actions, the driver determines
+how the tools should be connected (for example, using an inprocess
+module, pipes, temporary files, or user provided filenames). If an
+output file is required, the driver also computes the appropriate
+file name (the suffix and file location depend on the input types and
+options such as <tt class="docutils literal"><span class="pre">-save-temps</span></tt>).</p>
+<p>The driver interacts with a ToolChain to perform the Tool bindings.
+Each ToolChain contains information about all the tools needed for
+compilation for a particular architecture, platform, and operating
+system. A single driver invocation may query multiple ToolChains
+during one compilation in order to interact with tools for separate
+architectures.</p>
+<p>The results of this stage are not computed directly, but the driver
+can print the results via the <tt class="docutils literal"><span class="pre">-ccc-print-bindings</span></tt> option. For
+example:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> clang -ccc-print-bindings -arch i386 -arch ppc t0.c
+<span class="gp">#</span> <span class="s2">"i386-apple-darwin9"</span> - <span class="s2">"clang"</span>, inputs: <span class="o">[</span><span class="s2">"t0.c"</span><span class="o">]</span>, output: <span class="s2">"/tmp/cc-Sn4RKF.s"</span>
+<span class="gp">#</span> <span class="s2">"i386-apple-darwin9"</span> - <span class="s2">"darwin::Assemble"</span>, inputs: <span class="o">[</span><span class="s2">"/tmp/cc-Sn4RKF.s"</span><span class="o">]</span>, output: <span class="s2">"/tmp/cc-gvSnbS.o"</span>

+<span class="gp">#</span> <span class="s2">"ppc-apple-darwin9"</span> - <span class="s2">"gcc::Link"</span>, inputs: <span class="o">[</span><span class="s2">"/tmp/cc-WCdicw.o"</span><span class="o">]</span>, output: <span class="s2">"/tmp/cc-HHBEBh.out"</span>
+<span class="gp">#</span> <span class="s2">"i386-apple-darwin9"</span> - <span class="s2">"darwin::Lipo"</span>, inputs: <span class="o">[</span><span class="s2">"/tmp/cc-jgHQxi.out"</span>, <span class="s2">"/tmp/cc-HHBEBh.out"</span><span class="o">]</span>, output: <span class="s2">"a.out"</span>
+</pre></div>
+</div>
+<p>This shows the tool chain, tool, inputs and outputs which have been
+bound for this compilation sequence. Here clang is being used to
+compile t0.c on the i386 architecture and darwin specific versions of
+the tools are being used to assemble and link the result, but generic
+gcc versions of the tools are being used on PowerPC.</p>
+</li>
+<li><p class="first"><strong>Translate: Tool Specific Argument Translation</strong></p>
+<p>Once a Tool has been selected to perform a particular Action, the
+Tool must construct concrete Commands which will be executed during
+compilation. The main work is in translating from the gcc style
+command line options to whatever options the subprocess expects.</p>
+<p>Some tools, such as the assembler, only interact with a handful of
+arguments and just determine the path of the executable to call and
+pass on their input and output arguments. Others, like the compiler
+or the linker, may translate a large number of arguments in addition.</p>
+<p>The ArgList class provides a number of simple helper methods to
+assist with translating arguments; for example, to pass on only the
+last of arguments corresponding to some option, or all arguments for
+an option.</p>
+<p>The result of this stage is a list of Commands (executable paths and
+argument strings) to execute.</p>
+</li>
+<li><p class="first"><strong>Execute</strong></p>
+<p>Finally, the compilation pipeline is executed. This is mostly
+straightforward, although there is some interaction with options like
+<tt class="docutils literal"><span class="pre">-pipe</span></tt>, <tt class="docutils literal"><span class="pre">-pass-exit-codes</span></tt> and <tt class="docutils literal"><span class="pre">-time</span></tt>.</p>

+<p>The driver constructs a Compilation object for each set of command line

+single long lived driver instance to use for an entire build, for
+example.</p>
+<p>The Compilation object holds information that is particular to each

+<p>Parsing and pipelining both occur without reference to a Compilation
+instance. This is by design; the driver expects that both of these
+phases are platform neutral, with a few very well defined exceptions
+such as whether the platform uses a driver driver.</p>
+</div>
+<div class="section" id="toolchain-argument-translation">
+<h4><a class="toc-backref" href="#id15">ToolChain Argument Translation</a><a class="headerlink" href="#toolchain-argument-translation" title="Permalink to this headline">¶</a></h4>
+<p>In order to match gcc very closely, the clang driver currently allows
+tool chains to perform their own translation of the argument list (into
+a new ArgList data structure). Although this allows the clang driver to
+match gcc easily, it also makes the driver operation much harder to
+understand (since the Tools stop seeing some arguments the user
+provided, and see new ones instead).</p>
+<p>For example, on Darwin <tt class="docutils literal"><span class="pre">-gfull</span></tt> gets translated into two separate
+arguments, <tt class="docutils literal"><span class="pre">-g</span></tt> and <tt class="docutils literal"><span class="pre">-fno-eliminate-unused-debug-symbols</span></tt>. Trying to
+write Tool logic to do something with <tt class="docutils literal"><span class="pre">-gfull</span></tt> will not work, because
+Tool argument translation is done after the arguments have been
+translated.</p>
+<p>A long term goal is to remove this tool chain specific translation, and
+instead force each tool to change its own logic to do the right thing on
+the untranslated original arguments.</p>
+</div>
+<div class="section" id="unused-argument-warnings">
+<h4><a class="toc-backref" href="#id16">Unused Argument Warnings</a><a class="headerlink" href="#unused-argument-warnings" title="Permalink to this headline">¶</a></h4>
+<p>The driver operates by parsing all arguments but giving Tools the
+opportunity to choose which arguments to pass on. One downside of this
+infrastructure is that if the user misspells some option, or is confused
+about which options to use, some command line arguments the user really
+cared about may go unused. This problem is particularly important when
+using clang as a compiler, since the clang compiler does not support
+anywhere near all the options that gcc does, and we want to make sure
+users know which ones are being used.</p>
+<p>To support this, the driver maintains a bit associated with each
+argument of whether it has been used (at all) during the compilation.
+This bit usually doesn’t need to be set by hand, as the key ArgList
+accessors will set it automatically.</p>
+<p>When a compilation is successful (there are no errors), the driver
+checks the bit and emits an “unused argument” warning for any arguments
+which were never accessed. This is conservative (the argument may not
+have been used to do what the user wanted) but still catches the most
+obvious cases.</p>

+<h3><a class="toc-backref" href="#id26">Relation to GCC Driver Concepts</a><a class="headerlink" href="#relation-to-gcc-driver-concepts" title="Permalink to this headline">¶</a></h3>
+<p>For those familiar with the gcc driver, this section provides a brief
+overview of how things from the gcc driver map to the clang driver.</p>
+<ul>
+<li><p class="first"><strong>Driver Driver</strong></p>
+<p>The driver driver is fully integrated into the clang driver. The
+driver simply constructs additional Actions to bind the architecture
+during the <em>Pipeline</em> phase. The tool chain specific argument
+translation is responsible for handling <tt class="docutils literal"><span class="pre">-Xarch_</span></tt>.</p>
+<p>The one caveat is that this approach requires <tt class="docutils literal"><span class="pre">-Xarch_</span></tt> not be used
+to alter the compilation itself (for example, one cannot provide
+<tt class="docutils literal"><span class="pre">-S</span></tt> as an <tt class="docutils literal"><span class="pre">-Xarch_</span></tt> argument). The driver attempts to reject
+such invocations, and overall there isn’t a good reason to abuse
+<tt class="docutils literal"><span class="pre">-Xarch_</span></tt> to that end in practice.</p>
+<p>The upside is that the clang driver is more efficient and does little
+extra work to support universal builds. It also provides better error
+reporting and UI consistency.</p>
+</li>
+<li><p class="first"><strong>Specs</strong></p>
+<p>The clang driver has no direct correspondent for “specs”. The
+majority of the functionality that is embedded in specs is in the
+Tool specific argument translation routines. The parts of specs which
+control the compilation pipeline are generally part of the <em>Pipeline</em>
+stage.</p>
+</li>
+<li><p class="first"><strong>Toolchains</strong></p>
+<p>The gcc driver has no direct understanding of tool chains. Each gcc
+binary roughly corresponds to the information which is embedded
+inside a single ToolChain.</p>
+<p>The clang driver is intended to be portable and support complex
+compilation environments. All platform and tool chain specific code
+should be protected behind either abstract or well defined interfaces
+(such as whether the platform supports use as a driver driver).</p>

+<p>This page provides some examples of the kinds of things that people have
+done with Clang that might serve as useful guides (or starting points) from
+which to develop your own tools. They may be helpful even for something as
+banal (but necessary) as how to set up your build to integrate Clang.</p>
+<p>Clang’s library-based design is deliberately aimed at facilitating use by
+external projects, and we are always interested in improving Clang to
+better serve our external users. Some typical categories of applications
+where Clang is used are:</p>
+<ul class="simple">
+<li>Static analysis.</li>
+<li>Documentation/cross-reference generation.</li>
+</ul>
+<p>If you know of (or wrote!) a tool or project using Clang, please send an
+email to Clang’s <a class="reference external" href="http://lists.llvm.org/mailman/listinfo/cfe-dev">development discussion mailing list</a> to have it added.
+(or if you are already a Clang contributor, feel free to directly commit
+additions). Since the primary purpose of this page is to provide examples
+that can help developers, generally they must have code available.</p>

+<h1>How To Setup Clang Tooling For LLVM<a class="headerlink" href="#how-to-setup-clang-tooling-for-llvm" title="Permalink to this headline">¶</a></h1>
+<p>Clang Tooling provides infrastructure to write tools that need syntactic
+and semantic information about a program. This term also relates to a set
+of specific tools using this infrastructure (e.g. <tt class="docutils literal"><span class="pre">clang-check</span></tt>). This
+document provides information on how to set up and use Clang Tooling for
+the LLVM source code.</p>
+<div class="section" id="introduction">
+<h2>Introduction<a class="headerlink" href="#introduction" title="Permalink to this headline">¶</a></h2>
+<p>Clang Tooling needs a compilation database to figure out specific build
+options for each file. Currently it can create a compilation database
+from the <tt class="docutils literal"><span class="pre">compile_commands.json</span></tt> file, generated by CMake. When
+invoking clang tools, you can either specify a path to a build directory
+using a command line parameter <tt class="docutils literal"><span class="pre">-p</span></tt> or let Clang Tooling find this
+file in your source tree. In either case you need to configure your
+build using CMake to use clang tools.</p>
+</div>
+<div class="section" id="setup-clang-tooling-using-cmake-and-make">
+<h2>Setup Clang Tooling Using CMake and Make<a class="headerlink" href="#setup-clang-tooling-using-cmake-and-make" title="Permalink to this headline">¶</a></h2>
+<p>If you intend to use make to build LLVM, you should have CMake 2.8.6 or
+later installed (can be found <a class="reference external" href="http://cmake.org">here</a>).</p>
+<p>First, you need to generate Makefiles for LLVM with CMake. You need to
+make a build directory and run CMake from it:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> mkdir your/build/directory
+<span class="gp">$</span> <span class="nb">cd </span>your/build/directory
+<span class="gp">$</span> cmake -DCMAKE_EXPORT_COMPILE_COMMANDS<span class="o">=</span>ON path/to/llvm/sources
+</pre></div>
+</div>
+<p>If you want to use clang instead of GCC, you can add
+<tt class="docutils literal"><span class="pre">-DCMAKE_C_COMPILER=/path/to/clang</span> <span class="pre">-DCMAKE_CXX_COMPILER=/path/to/clang++</span></tt>.
+You can also use <tt class="docutils literal"><span class="pre">ccmake</span></tt>, which provides a curses interface to configure
+CMake variables for lazy people.</p>
+<p>As a result, the new <tt class="docutils literal"><span class="pre">compile_commands.json</span></tt> file should appear in the
+current directory. You should link it to the LLVM source tree so that
+Clang Tooling is able to use it:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> ln -s <span class="nv">$PWD</span>/compile_commands.json path/to/llvm/source/
+</pre></div>
+</div>
+<p>Now you are ready to build and test LLVM using make:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> make check-all
+</pre></div>
+</div>
+</div>
+<div class="section" id="using-clang-tools">
+<h2>Using Clang Tools<a class="headerlink" href="#using-clang-tools" title="Permalink to this headline">¶</a></h2>
+<p>After you completed the previous steps, you are ready to run clang tools. If
+you have a recent clang installed, you should have <tt class="docutils literal"><span class="pre">clang-check</span></tt> in
+<tt class="docutils literal"><span class="pre">$PATH</span></tt>. Try to run it on any <tt class="docutils literal"><span class="pre">.cpp</span></tt> file inside the LLVM source tree:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> clang-check tools/clang/lib/Tooling/CompilationDatabase.cpp
+</pre></div>
+</div>
+<p>If you’re using vim, it’s convenient to have clang-check integrated. Put
+this into your <tt class="docutils literal"><span class="pre">.vimrc</span></tt>:</p>
+<div class="highlight-python"><pre>function! ClangCheckImpl(cmd)
+ if &autowrite | wall | endif
+ echo "Running " . a:cmd . " ..."
+ let l:output = system(a:cmd)
+ cexpr l:output
+ cwindow
+ let w:quickfix_title = a:cmd
+ if v:shell_error != 0
+ cc
+ endif
+ let g:clang_check_last_cmd = a:cmd
+endfunction
+
+function! ClangCheck()
+ let l:filename = expand('%')
+ if l:filename =~ '\.\(cpp\|cxx\|cc\|c\)$'
+ call ClangCheckImpl("clang-check " . l:filename)
+ elseif exists("g:clang_check_last_cmd")
+ call ClangCheckImpl(g:clang_check_last_cmd)
+ else
+ echo "Can't detect file's compilation arguments and no previous clang-check invocation!"
+ endif
+endfunction
+
+nmap <silent> <F5> :call ClangCheck()<CR><CR></pre>
+</div>
+<p>When editing a .cpp/.cxx/.cc/.c file, hit F5 to reparse the file. In
+case the current file has a different extension (for example, .h), F5
+will re-run the last clang-check invocation made from this vim instance
+(if any). The output will go into the error window, which is opened
+automatically when clang-check finds errors, and can be re-opened with
+<tt class="docutils literal"><span class="pre">:cope</span></tt>.</p>
+<p>Other <tt class="docutils literal"><span class="pre">clang-check</span></tt> options that can be useful when working with clang
+AST:</p>
+<ul class="simple">
+<li><tt class="docutils literal"><span class="pre">-ast-print</span></tt> — Build ASTs and then pretty-print them.</li>
+<li><tt class="docutils literal"><span class="pre">-ast-dump</span></tt> — Build ASTs and then debug dump them.</li>
+<li><tt class="docutils literal"><span class="pre">-ast-dump-filter=<string></span></tt> — Use with <tt class="docutils literal"><span class="pre">-ast-dump</span></tt> or <tt class="docutils literal"><span class="pre">-ast-print</span></tt> to
+dump/print only AST declaration nodes having a certain substring in a
+qualified name. Use <tt class="docutils literal"><span class="pre">-ast-list</span></tt> to list all filterable declaration node
+names.</li>
+<li><tt class="docutils literal"><span class="pre">-ast-list</span></tt> — Build ASTs and print the list of declaration node qualified
+names.</li>

+<h2>(Experimental) Using Ninja Build System<a class="headerlink" href="#experimental-using-ninja-build-system" title="Permalink to this headline">¶</a></h2>
+<p>Optionally you can use the <a class="reference external" href="https://github.com/martine/ninja">Ninja</a>
+build system instead of make. It is aimed at making your builds faster.
+Currently this step will require building Ninja from sources.</p>
+<p>To take advantage of using Clang Tools along with Ninja build you need
+at least CMake 2.8.9.</p>
+<p>Clone the Ninja git repository and build Ninja from sources:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> git clone git://github.com/martine/ninja.git
+<span class="gp">$</span> <span class="nb">cd </span>ninja/
+<span class="gp">$</span> ./bootstrap.py
+</pre></div>
+</div>
+<p>This will result in a single binary <tt class="docutils literal"><span class="pre">ninja</span></tt> in the current directory.
+It doesn’t require installation and can just be copied to any location
+inside <tt class="docutils literal"><span class="pre">$PATH</span></tt>, say <tt class="docutils literal"><span class="pre">/usr/local/bin/</span></tt>:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> sudo cp ninja /usr/local/bin/
+<span class="gp">$</span> sudo chmod a+rx /usr/local/bin/ninja
+</pre></div>
+</div>
+<p>After doing all of this, you’ll need to generate Ninja build files for
+LLVM with CMake. You need to make a build directory and run CMake from
+it:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> mkdir your/build/directory
+<span class="gp">$</span> <span class="nb">cd </span>your/build/directory
+<span class="gp">$</span> cmake -G Ninja -DCMAKE_EXPORT_COMPILE_COMMANDS<span class="o">=</span>ON path/to/llvm/sources
+</pre></div>
+</div>
+<p>If you want to use clang instead of GCC, you can add
+<tt class="docutils literal"><span class="pre">-DCMAKE_C_COMPILER=/path/to/clang</span> <span class="pre">-DCMAKE_CXX_COMPILER=/path/to/clang++</span></tt>.
+You can also use <tt class="docutils literal"><span class="pre">ccmake</span></tt>, which provides a curses interface to configure
+CMake variables in an interactive manner.</p>
+<p>As a result, the new <tt class="docutils literal"><span class="pre">compile_commands.json</span></tt> file should appear in the
+current directory. You should link it to the LLVM source tree so that
+Clang Tooling is able to use it:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> ln -s <span class="nv">$PWD</span>/compile_commands.json path/to/llvm/source/
+</pre></div>
+</div>
+<p>Now you are ready to build and test LLVM using Ninja:</p>
+<div class="highlight-console"><div class="highlight"><pre><span class="gp">$</span> ninja check-all
+</pre></div>
+</div>
+<p>Other target names can be used in the same way as with make.</p>
