+This directory contains support files to build libc++ with
+the Android NDK for ARM, x86 and MIPS.
+
+You need a recent NDK release, one which provides a version
+of the GAbi++ C++ runtime that supports rtti _and_ exceptions.
+
+Build instructions:
+
+  1/ Set NDK to the path of a recent Android NDK install path
+     (Use Android NDK r8c or above), e.g.:
+
+      NDK=$HOME/android/ndk-r8c
+
+  2/ From the top-level directory, do:
+
+      $NDK/ndk-build -C android/test
+
+     This is actually equivalent to:
+
+      cd android/test
+      $NDK/ndk-build
+
+  3/ To see build commands, use V=1, as in:
+
+      $NDK/ndk-build -C android/test V=1
+
+
+Android support files:
+
+  include/support/android:
+     Android system header wrappers, to add missing declarations
+
+  src/support/android:
+     Put the implementation of the missing system functions here.
+
+  android/llvm-libc++/Android.mk:
+     Main build file for the library. This builds one static and
+     one shared version of the library.
+
+     If modifications are not obvious, read $NDK/docs/ANDROID-MK.html
+     for a description of the Android.mk format.
+
+  android/test/jni:
+     NDK build project for two test programs that link against the
+     static and shared versions of the library.
+
+     See the Android.mk and Application.mk files in this directory
+     if you want to add new test files.
+
+
+Toolchain selection:
+  By default, ndk-build tries to build with GCC 4.6, however, experimental
+  versions of GCC 4.7 and Clang 3.1 are available with recent NDK releases.
+
+  Use the NDK_TOOLCHAIN_VERSION environment variable to switch to a
+  different one, valid examples:
+
+
+    export NDK_TOOLCHAIN_VERSION=4.6    # this is the default
+    $NDK/ndk-build -C android/test
+
+    # This is equivalent, but for GCC 4.7
+    $NDK/ndk-build -C android/test NDK_TOOLCHAIN_VERSION=4.7
+
+    # Also equivalent, but for Clang 3.1
+    NDK_TOOLCHAIN_VERSION=Clang3.1 $NDK/ndk-build -C android/test

+Each algorithm herein assumes that __root->__parent_ points to a non-null
+structure which has a member __left_ which points back to __root.  No other
+member is read or written to at __root->__parent_.
+
+__root->__parent_ will be referred to below (in comments only) as end_node.
+end_node->__left_ is an externably accessible lvalue for __root, and can be
+changed by node insertion and removal (without explicit reference to end_node).
+
+All nodes (with the exception of end_node), even the node referred to as
+__root, have a non-null __parent_ field.

+// The algorithm creates a list of small primes, plus an open-ended list of
+// potential primes.  All prime numbers are potential prime numbers.  However
+// some potential prime numbers are not prime.  In an ideal world, all potential
+// prime numbers would be prime.  Candiate prime numbers are chosen as the next
+// highest potential prime.  Then this number is tested for prime by dividing it
+// by all potential prime numbers less than the sqrt of the candidate.
+//
+// This implementation defines potential primes as those numbers not divisible
+// by 2, 3, 5, and 7.  Other (common) implementations define potential primes
+// as those not divisible by 2.  A few other implementations define potential
+// primes as those not divisible by 2 or 3.  By raising the number of small
+// primes which the potential prime is not divisible by, the set of potential
+// primes more closely approximates the set of prime numbers.  And thus there
+// are fewer potential primes to search, and fewer potential primes to divide
+// against.

+// __scan_keyword
+// Scans [__b, __e) until a match is found in the basic_strings range
+//  [__kb, __ke) or until it can be shown that there is no match in [__kb, __ke).
+//  __b will be incremented (visibly), consuming CharT until a match is found
+//  or proved to not exist.  A keyword may be "", in which will match anything.
+//  If one keyword is a prefix of another, and the next CharT in the input
+//  might match another keyword, the algorithm will attempt to find the longest
+//  matching keyword.  If the longer matching keyword ends up not matching, then
+//  no keyword match is found.  If no keyword match is found, __ke is returned.
+//  Else an iterator pointing to the matching keyword is found.  If more than
+//  one keyword matches, an iterator to the first matching keyword is returned.
+//  If on exit __b == __e, eofbit is set in __err.  If __case_senstive is false,
+//  __ct is used to force to lower case before comparing characters.
+//  Examples:
+//  Keywords:  "a", "abb"
+//  If the input is "a", the first keyword matches and eofbit is set.
+//  If the input is "abc", no match is found and "ab" are consumed.

+  <h1>&lt;atomic&gt; design</h1>
+  <!--*********************************************************************-->
+
+<p>
+There are currently 3 designs under consideration.  They differ in where most
+of the implmentation work is done.  The functionality exposed to the customer
+should be identical (and conforming) for all three designs.
+</p>
+
+<ol type="A">
+<li>
+<a href="atomic_design_a.html">Minimal work for the library</a>
+</li>
+<li>
+<a href="atomic_design_b.html">Something in between</a>
+</li>
+<li>
+<a href="atomic_design_c.html">Minimal work for the front end</a>
+</li>
+</ol>
+
+<p>
+With any design, the (back end) compiler writer should note:
+</p>
+
+<blockquote>
+<p>
+The decision to implement lock-free operations on any given type (or not) is an
+ABI-binding decision.  One can not change from treating a type as not lock free,
+to lock free (or vice-versa) without breaking your ABI.
+</p>
+
+<p>
+Example:
+</p>
+
+<blockquote><pre>
+TU1.cc
+-----------
+extern atomic&lt;long long&gt; A;
+int foo() { return A.compare_exchange_strong(w, x); }
+
+TU2.cc
+-----------
+extern atomic&lt;long long&gt; A;
+void bar() { return A.compare_exchange_strong(y, z); }
+</pre></blockquote>
+</blockquote>
+
+<p>
+If only <em>one</em> of these calls to <tt>compare_exchange_strong</tt> is
+implemented with mutex-locked code, then that mutex-locked code will not be
+executed mutually exclusively of the one implemented in a lock-free manner.
+</p>

+The compiler supplies all of the intrinsics as described below.  This list of
+intrinsics roughly parallels the requirements of the C and C++ atomics
+proposals.  The C and C++ library imlpementations simply drop through to these
+intrinsics.  Anything the platform does not support in hardware, the compiler
+arranges for a (compiler-rt) library call to be made which will do the job with
+a mutex, and in this case ignoring the memory ordering parameter (effectively
+implementing <tt>memory_order_seq_cst</tt>).
+</p>
+
+<p>
+Ultimate efficiency is preferred over run time error checking.  Undefined
+behavior is acceptable when the inputs do not conform as defined below.

+<p>
+This is a variation of design A which puts the burden on the library to arrange
+for the correct manipulation of the run time memory ordering arguments, and only
+calls the compiler for well-defined memory orderings.  I think of this design as
+the worst of A and C, instead of the best of A and C.  But I offer it as an
+option in the spirit of completeness.

+  <h1>&lt;atomic&gt; design</h1>
+  <!--*********************************************************************-->
+
+<p>
+The <tt>&lt;atomic&gt;</tt> header is one of the most closely coupled headers to
+the compiler.  Ideally when you invoke any function from
+<tt>&lt;atomic&gt;</tt>, it should result in highly optimized assembly being
+inserted directly into your application ...  assembly that is not otherwise
+representable by higher level C or C++ expressions.  The design of the libc++
+<tt>&lt;atomic&gt;</tt> header started with this goal in mind.  A secondary, but
+still very important goal is that the compiler should have to do minimal work to
+faciliate the implementaiton of <tt>&lt;atomic&gt;</tt>.  Without this second
+goal, then practically speaking, the libc++ <tt>&lt;atomic&gt;</tt> header would
+be doomed to be a barely supported, second class citizen on almost every
+platform.
+</p>
+
+<p>Goals:</p>
+
+<blockquote><ul>
+<li>Optimal code generation for atomic operations</li>
+<li>Minimal effort for the compiler to achieve goal 1 on any given platform</li>
+<li>Conformance to the C++0X draft standard</li>
+</ul></blockquote>
+
+<p>
+The purpose of this document is to inform compiler writers what they need to do
+to enable a high performance libc++ <tt>&lt;atomic&gt;</tt> with minimal effort.
+</p>
+
+<h2>The minimal work that must be done for a conforming <tt>&lt;atomic&gt;</tt></h2>
+
+<p>
+The only "atomic" operations that must actually be lock free in
+<tt>&lt;atomic&gt;</tt> are represented by the following compiler intrinsics:
+</p>
+
+<blockquote><pre>
+__atomic_flag__
+__atomic_exchange_seq_cst(__atomic_flag__ volatile* obj, __atomic_flag__ desr)
+{
+    unique_lock&lt;mutex&gt; _(some_mutex);
+    __atomic_flag__ result = *obj;
+    *obj = desr;
+    return result;
+}
+
+void
+__atomic_store_seq_cst(__atomic_flag__ volatile* obj, __atomic_flag__ desr)
+{
+    unique_lock&lt;mutex&gt; _(some_mutex);
+    *obj = desr;
+}
+</pre></blockquote>
+
+<p>
+Where:
+</p>
+
+<blockquote><ul>
+<li>
+If <tt>__has_feature(__atomic_flag)</tt> evaluates to 1 in the preprocessor then
+the compiler must define <tt>__atomic_flag__</tt> (e.g. as a typedef to
+<tt>int</tt>).
+</li>
+<li>
+If <tt>__has_feature(__atomic_flag)</tt> evaluates to 0 in the preprocessor then
+the library defines <tt>__atomic_flag__</tt> as a typedef to <tt>bool</tt>.
+</li>
+<li>
+<p>
+To communicate that the above intrinsics are available, the compiler must
+arrange for <tt>__has_feature</tt> to return 1 when fed the intrinsic name
+appended with an '_' and the mangled type name of <tt>__atomic_flag__</tt>.
+</p>
+<p>
+For example if <tt>__atomic_flag__</tt> is <tt>unsigned int</tt>:
+</p>
+<blockquote><pre>
+__has_feature(__atomic_flag) == 1
+__has_feature(__atomic_exchange_seq_cst_j) == 1
+__has_feature(__atomic_store_seq_cst_j) == 1
+
+typedef unsigned int __atomic_flag__; 
+
+unsigned int __atomic_exchange_seq_cst(unsigned int volatile*, unsigned int)
+{
+   // ...
+}
+
+void __atomic_store_seq_cst(unsigned int volatile*, unsigned int)
+{
+   // ...
+}
+</pre></blockquote>
+</li>
+</ul></blockquote>
+
+<p>
+That's it!  Compiler writers do the above and you've got a fully conforming
+(though sub-par performance) <tt>&lt;atomic&gt;</tt> header!
+</p>
+
+<h2>Recommended work for a higher performance <tt>&lt;atomic&gt;</tt></h2>
+
+<p>
+It would be good if the above intrinsics worked with all integral types plus
+<tt>void*</tt>.  Because this may not be possible to do in a lock-free manner for
+all integral types on all platforms, a compiler must communicate each type that
+an intrinsic works with.  For example if <tt>__atomic_exchange_seq_cst</tt> works
+for all types except for <tt>long long</tt> and <tt>unsigned long long</tt>
+then:
+</p>
+
+<blockquote><pre>
+__has_feature(__atomic_exchange_seq_cst_b) == 1  // bool
+__has_feature(__atomic_exchange_seq_cst_c) == 1  // char
+__has_feature(__atomic_exchange_seq_cst_a) == 1  // signed char
+__has_feature(__atomic_exchange_seq_cst_h) == 1  // unsigned char
+__has_feature(__atomic_exchange_seq_cst_Ds) == 1 // char16_t
+__has_feature(__atomic_exchange_seq_cst_Di) == 1 // char32_t
+__has_feature(__atomic_exchange_seq_cst_w) == 1  // wchar_t
+__has_feature(__atomic_exchange_seq_cst_s) == 1  // short
+__has_feature(__atomic_exchange_seq_cst_t) == 1  // unsigned short
+__has_feature(__atomic_exchange_seq_cst_i) == 1  // int
+__has_feature(__atomic_exchange_seq_cst_j) == 1  // unsigned int
+__has_feature(__atomic_exchange_seq_cst_l) == 1  // long
+__has_feature(__atomic_exchange_seq_cst_m) == 1  // unsigned long
+__has_feature(__atomic_exchange_seq_cst_Pv) == 1 // void*
+</pre></blockquote>
+
+<p>
+Note that only the <tt>__has_feature</tt> flag is decorated with the argument
+type.  The name of the compiler intrinsic is not decorated, but instead works
+like a C++ overloaded function.
+</p>
+
+<p>
+Additionally there are other intrinsics besides
+<tt>__atomic_exchange_seq_cst</tt> and <tt>__atomic_store_seq_cst</tt>.  They
+are optional.  But if the compiler can generate faster code than provided by the
+library, then clients will benefit from the compiler writer's expertise and
+knowledge of the targeted platform.
+</p>
+
+<p>
+Below is the complete list of <i>sequentially consistent</i> intrinsics, and
+their library implementations.  Template syntax is used to indicate the desired
+overloading for integral and void* types.  The template does not represent a
+requirement that the intrinsic operate on <em>any</em> type!

+One should consult the (currently draft)
+<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3126.pdf">C++ standard</a>
+for the details of the definitions for these operations.  For example
+<tt>__atomic_compare_exchange_weak_seq_cst_seq_cst</tt> is allowed to fail
+spuriously while <tt>__atomic_compare_exchange_strong_seq_cst_seq_cst</tt> is
+not.
+</p>
+
+<p>
+If on your platform the lock-free definition of
+<tt>__atomic_compare_exchange_weak_seq_cst_seq_cst</tt> would be the same as
+<tt>__atomic_compare_exchange_strong_seq_cst_seq_cst</tt>, you may omit the
+<tt>__atomic_compare_exchange_weak_seq_cst_seq_cst</tt> intrinsic without a
+performance cost.  The library will prefer your implementation of
+<tt>__atomic_compare_exchange_strong_seq_cst_seq_cst</tt> over its own
+definition for implementing
+<tt>__atomic_compare_exchange_weak_seq_cst_seq_cst</tt>.  That is, the library
+will arrange for <tt>__atomic_compare_exchange_weak_seq_cst_seq_cst</tt> to call
+<tt>__atomic_compare_exchange_strong_seq_cst_seq_cst</tt> if you supply an
+intrinsic for the strong version but not the weak.
+</p>
+
+<h2>Taking advantage of weaker memory synchronization</h2>
+
+<p>
+So far all of the intrinsics presented require a <em>sequentially
+consistent</em> memory ordering.  That is, no loads or stores can move across
+the operation (just as if the library had locked that internal mutex).  But
+<tt>&lt;atomic&gt;</tt> supports weaker memory ordering operations.  In all,
+there are six memory orderings (listed here from strongest to weakest):
+</p>
+
+<blockquote><pre>
+memory_order_seq_cst
+memory_order_acq_rel
+memory_order_release
+memory_order_acquire
+memory_order_consume
+memory_order_relaxed
+</pre></blockquote>
+
+<p>
+(See the
+<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3126.pdf">C++ standard</a>
+for the detailed definitions of each of these orderings).
+</p>
+
+<p>
+On some platforms, the compiler vendor can offer some or even all of the above
+intrinsics at one or more weaker levels of memory synchronization.  This might
+lead for example to not issuing an <tt>mfence</tt> instruction on the x86.
+</p>
+
+<p>
+If the compiler does not offer any given operation, at any given memory ordering
+level, the library will automatically attempt to call the next highest memory
+ordering operation.  This continues up to <tt>seq_cst</tt>, and if that doesn't
+exist, then the library takes over and does the job with a <tt>mutex</tt>.  This
+is a compile-time search &amp; selection operation.  At run time, the
+application will only see the few inlined assembly instructions for the selected
+intrinsic.
+</p>
+
+<p>
+Each intrinsic is appended with the 7-letter name of the memory ordering it
+addresses.  For example a <tt>load</tt> with <tt>relaxed</tt> ordering is
+defined by:
+</p>
+
+<blockquote><pre>
+T __atomic_load_relaxed(const volatile T* obj);
+</pre></blockquote>
+
+<p>
+And announced with:
+</p>
+
+<blockquote><pre>
+__has_feature(__atomic_load_relaxed_b) == 1  // bool
+__has_feature(__atomic_load_relaxed_c) == 1  // char
+__has_feature(__atomic_load_relaxed_a) == 1  // signed char
+...
+</pre></blockquote>
+
+<p>
+The <tt>__atomic_compare_exchange_strong(weak)</tt> intrinsics are parameterized
+on two memory orderings.  The first ordering applies when the operation returns
+<tt>true</tt> and the second ordering applies when the operation returns
+<tt>false</tt>.
+</p>
+
+<p>
+Not every memory ordering is appropriate for every operation.  <tt>exchange</tt>
+and the <tt>fetch_<i>op</i></tt> operations support all 6.  But <tt>load</tt>
+only supports <tt>relaxed</tt>, <tt>consume</tt>, <tt>acquire</tt> and <tt>seq_cst</tt>.
+<tt>store</tt>
+only supports <tt>relaxed</tt>, <tt>release</tt>, and <tt>seq_cst</tt>.  The
+<tt>compare_exchange</tt> operations support the following 16 combinations out
+of the possible 36:
+</p>
+
+<blockquote><pre>
+relaxed_relaxed
+consume_relaxed
+consume_consume
+acquire_relaxed
+acquire_consume
+acquire_acquire
+release_relaxed
+release_consume
+release_acquire
+acq_rel_relaxed
+acq_rel_consume
+acq_rel_acquire
+seq_cst_relaxed
+seq_cst_consume
+seq_cst_acquire
+seq_cst_seq_cst
+</pre></blockquote>
+
+<p>
+Again, the compiler supplies intrinsics only for the strongest orderings where
+it can make a difference.  The library takes care of calling the weakest
+supplied intrinsic that is as strong or stronger than the customer asked for.

+
+  <p>All of the code in libc++ is <a

+     under the MIT license and the UIUC License (a BSD-like license).</p>
+
+  <!--=====================================================================-->
+  <h2 id="goals">Features and Goals</h2>
+  <!--=====================================================================-->
+
+    <ul>
+        <li>Correctness as defined by the C++11 standard.</li>
+        <li>Fast execution.</li>
+        <li>Minimal memory use.</li>
+        <li>Fast compile times.</li>
+        <li>ABI compatibility with gcc's libstdc++ for some low-level features

+    </ul>
+
+  <!--=====================================================================-->
+  <h2 id="why">Why a new C++ Standard Library for C++11?</h2>
+  <!--=====================================================================-->
+
+  <p>After its initial introduction, many people have asked "why start a new
+     library instead of contributing to an existing library?" (like Apache's
+     libstdcxx, GNU's libstdc++, STLport, etc).  There are many contributing
+     reasons, but some of the major ones are:</p>
+
+  <ul>
+  <li><p>From years of experience (including having implemented the standard
+      library before), we've learned many things about implementing
+      the standard containers which require ABI breakage and fundamental changes
+      to how they are implemented.  For example, it is generally accepted that
+      building std::string using the "short string optimization" instead of
+      using Copy On Write (COW) is a superior approach for multicore
+      machines (particularly in C++11, which has rvalue references).  Breaking
+      ABI compatibility with old versions of the library was
+      determined to be critical to achieving the performance goals of
+      libc++.</p></li>
+
+  <li><p>Mainline libstdc++ has switched to GPL3, a license which the developers
+      of libc++ cannot use.  libstdc++ 4.2 (the last GPL2 version) could be
+      independently extended to support C++11, but this would be a fork of the
+      codebase (which is often seen as worse for a project than starting a new
+      independent one).  Another problem with libstdc++ is that it is tightly
+       integrated with G++ development, tending to be tied fairly closely to the
+       matching version of G++.</p>
+    </li>
+
+  <li><p>STLport and the Apache libstdcxx library are two other popular
+      candidates, but both lack C++11 support.  Our experience (and the
+      experience of libstdc++ developers) is that adding support for C++11 (in
+      particular rvalue references and move-only types) requires changes to
+      almost every class and function, essentially amounting to a rewrite.
+      Faced with a rewrite, we decided to start from scratch and evaluate every
+      design decision from first principles based on experience.</p>
+
+      <p>Further, both projects are apparently abandoned: STLport 5.2.1 was
+      released in Oct'08, and STDCXX 4.2.1 in May'08.</p>
+
+    </ul>
+
+  <!--=====================================================================-->
+  <h2 id="requirements">Platform Support</h2>
+  <!--=====================================================================-->
+
+   <p>libc++ is known to work on the following platforms, using g++-4.2 and
+      clang (lack of C++11 language support disables some functionality).</p>
+
+    <ul>
+     <li>Mac OS X i386</li>
+     <li>Mac OS X x86_64</li>
+    </ul>
+
+  <!--=====================================================================-->
+  <h2 id="dir-structure">Current Status</h2>
+  <!--=====================================================================-->
+
+   <p>libc++ is a 100% complete C++11 implementation on Apple's OS X. </p>
+   <p>LLVM and Clang can self host in C++ and C++11 mode with libc++ on Linux.</p>
+
+   <p>
+   Ports to other platforms are underway. Here are recent test
+   results for <a href="results.Windows.html">Windows</a>
+   and <a href="results.Linux.html">Linux</a>.
+   </p>
+
+  <!--=====================================================================-->
+  <h2>Get it and get involved!</h2>
+  <!--=====================================================================-->
+
+  <p>First please review our
+     <a href="http://llvm.org/docs/DeveloperPolicy.html">Developer's Policy</a>.
+
+  <p>To check out the code, use:</p>
+
+  <ul>
+  <li><code>svn co http://llvm.org/svn/llvm-project/libcxx/trunk libcxx</code></li>
+  </ul>
+
+  <p>
+     On Mac OS 10.7 (Lion) and later, the easiest way to get this library is to install
+     Xcode 4.2 or later.  However if you want to install tip-of-trunk from here
+     (getting the bleeding edge), read on.  However, be warned that Mac OS
+     10.7 will not boot without a valid copy of <code>libc++.1.dylib</code> in
+     <code>/usr/lib</code>.
+  </p>
+
+  <p>
+     Next:
+  </p>
+  
+  <ul>
+    <li><code>cd libcxx/lib</code></li>
+    <li><code>export TRIPLE=-apple-</code></li>
+    <li><code>./buildit</code></li>
+    <li><code>ln -sf libc++.1.dylib libc++.dylib</code></li>
+  </ul>
+  
+  <p>
+     That should result in a libc++.1.dylib and libc++.dylib.  The safest thing
+     to do is to use it from where your libcxx is installed instead of replacing
+     these in your Mac OS.
+  </p>
+
+  <p>
+  To use your system-installed libc++ with clang you can:
+  </p>
+
+  <ul>
+    <li><code>clang++ -stdlib=libc++ test.cpp</code></li>
+    <li><code>clang++ -std=c++11 -stdlib=libc++ test.cpp</code></li>
+  </ul>
+
+  <p>
+  To use your tip-of-trunk libc++ on Mac OS with clang you can:
+  </p>
+
+  <ul>
+    <li><code>export DYLD_LIBRARY_PATH=&lt;path-to-libcxx&gt;/lib</code>
+    <li><code>clang++ -std=c++11 -stdlib=libc++ -nostdinc++
+         -I&lt;path-to-libcxx&gt;/include -L&lt;path-to-libcxx&gt;/lib
+         test.cpp</code></li>
+  </ul>
+
+  <p>To run the libc++ test suite (recommended):</p>
+
+  <ul>
+  <li><code>cd libcxx/test</code></li>
+  <li><code>./testit</code></li>
+     <ul>
+       <li>You can alter the command line options <code>testit</code> uses
+       with <code>export OPTIONS="whatever you need"</code></li>
+     </ul>
+  </ul>
+
+  <!--=====================================================================-->
+  <h3>Notes</h3>
+  <!--=====================================================================-->
+
+<p>
+Building libc++ with <code>-fno-rtti</code> is not supported.  However linking
+against it with <code>-fno-rtti</code> is supported.
+</p>

+  <p>Send discussions to the
+  (<a href="http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev">clang mailing list</a>).</p>
+
+  <!--=====================================================================-->
+  <h2>Build on Linux using CMake and libsupc++.</h2>
+  <!--=====================================================================-->
+
+  <p>
+     You will need libstdc++ in order to provide libsupc++.
+  </p>
+  
+  <p>
+     Figure out where the libsupc++ headers are on your system. On Ubuntu this
+     is <code>/usr/include/c++/&lt;version&gt;</code> and
+     <code>/usr/include/c++/&lt;version&gt;/&lt;target-triple&gt;</code>
+  </p>
+  
+  <p>
+     You can also figure this out by running
+     <pre>
+$ echo | g++ -Wp,-v -x c++ - -fsyntax-only
+ignoring nonexistent directory "/usr/local/include/x86_64-linux-gnu"
+ignoring nonexistent directory "/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/include"
+#include "..." search starts here:

+ /usr/lib/gcc/x86_64-linux-gnu/4.7/include-fixed
+ /usr/include/x86_64-linux-gnu
+ /usr/include
+End of search list.
+     </pre>
+
+      Note the first two entries happen to be what we are looking for. This
+      may not be correct on other platforms.
+  </p>
+  
+  <p>
+     We can now run CMake:
+     <ul>
+       <li><code>CC=clang CXX=clang++ cmake -G "Unix Makefiles"
+                -DLIBCXX_CXX_ABI=libsupc++
+                -DLIBCXX_LIBSUPCXX_INCLUDE_PATHS="/usr/include/c++/4.7/;/usr/include/c++/4.7/x86_64-linux-gnu/"
+                -DCMAKE_BUILD_TYPE=Release
+                -DCMAKE_INSTALL_PREFIX=/usr
+                &lt;libc++-source-dir&gt;</code></li>
+       <li><code>make</code></li>
+       <li><code>sudo make install</code></li>
+     </ul>
+     <p>
+        You can now run clang with -stdlib=libc++.
+     </p>

+All failures in the libc++ test suite will be documented here.
+
+Last run was with Clang (pre-3.1) and GCC 4.6.3 (with dw2 exception handling) and
+ mingw-w64 v2.0.3 on i686-w64-mingw32.
+
+The following line was added to ./lib/buildit to make a static libc++ library because a DLL requires "declspec(dllexport)" or a .def file:
+ar rcs libc++.a *.o
+I also deleted libc++.dll and libc++.dll.a to make sure libc++ was linked statically to prevent unrelated issues from contaminating the test results.
+The commands to build and test were (-nodefaultlibs does not work, lots of MinGW related stuff gets left out resulting in linker failures):
+TRIPLE=i686-w64-mingw32 ./buildit
+TRIPLE=i686-w64-mingw32 HEADER_INCLUDE="-I/home/Ruben/libcxx/include" LIBS="-L/home/ruben/libcxx/lib -lc++ -lpthread -lsupc++ -lmsvcr100 -Wl,--allow-multiple-definition" ./testit > test.log 2>&1
+
+Note: Some locale tests may "Need investigating", but I think most problems are
+      caused by wrong/unportable locale naming in the tests.
+Note: Some tests failed to link because "test.exe" was still running when ld.exe
+      tried to link the next test. I left these failures out of the list; they
+      account for about 10-30 failures, and are counted in the total scores below.
+      I reran some of these failures manually and they passed.
+Note: Some tests fail at runtime but pass when run manually. Usage of std::cout
+      segfaults so further investigation is difficult. These also contribute to
+      the failures total, but are left out of the failure list, as the cause is
+      probably not located in that part of libc++, not locatable due to the lack
+      of usable debug info generated by Clang at this time.
