<dl>
<dt>Important changes:</dt>
<dd>
<ul>
<li>Added the GNU Compiler Collection (GCC) 4.7 compiler to the NDK. The GCC 4.6 compiler
is still the default, so you must to explicitly enable the new version as follows:
<ul>
<li>For {@code ndk-build}, export the {@code NDK_TOOLCHAIN_VERSION=4.7} variable
<em>or</em> add it to {@code Application.mk}.</li>
<li>For standalone builds, add the {@code --toolchain=} option to
{@code make-standalone-toolchain.sh}, for example:
<pre>--toolchain=arm-linux-androideabi-4.7</pre></li>
</ul>
<p class="note">
<strong>Note:</strong> This feature is experimental. Please try it and
<a href="http://code.google.com/p/android/issues/list">report any issues</a>.</p>
</li>
<li>Added {@code stlport} exception support via gabi++. Note that the new gabi++
depends on {@code dlopen} and related code, meaning that:
<ul>
<li>You can no longer build a <em>static</em> executable using the {@code -static}
option or include {@code libstlport_static.a} using
{@code APP_STL := stlport_static}. (You can still use the {@code -static} option
with a standalone toolchain.) Compiling a <em>dynamic</em> executable using
{@code include $(BUILD_EXECUTABLE)} continues to work because the compiler
automatically adds the {@code -ldl} option.</li>
<li>If your project links using {@code -nostdlib} and {-Wl,--no-undefined}, you
must manually include the {@code -ldl} option.</li>
</ul>
For more information, see {@code CPLUSPLUS-SUPPORT.html}.
<p class="note">
<strong>Note:</strong> This feature is experimental and works better with the GCC
4.6/4.7 compilers than with GCC 4.4.3 or Clang 3.1. Please try it and
<a href="http://code.google.com/p/android/issues/list">report any issues</a>.</p>
</li>
<li>Added a {@code -mstack-protector-guard=} option for x86 to choose between a
<em>global</em> default path which is compatible with older Android C library (bionic)
and a new <em>tls</em> path (%gs:20) for {@code -fstack-protector},
{@code -fstack-protector-all} and {@code -fstack-protector-strong} using the GCC 4.6
and higher compilers.
<p class="note">
<strong>Note:</strong> The {@code -mstack-protector-guard} setting itself does not
enable any {@code -fstack-protector*} options.</p>
</li>
<li>Added {@code android_setCpu()} function to
{@code sources/android/cpufeatures/cpu-features.c} for use when auto-detection via
{@code /proc} is not possible in Android 4.1 and higher.

164154</a>)</li>
</ul>
</dd>
<dt>Important bug fixes:</dt>
<dd>
<ul>
<li>Fixed unnecessary rebuild of object files when using the {@code ndk-build} script.
(<a href="http://code.google.com/p/android/issues/detail?id=39810">Issue 39810</a>)</li>
<li>Fixed a linker failure with the NDK 8c release for Mac OS X 10.6.x that produced the
following error:
<pre>
dyld: lazy symbol binding failed: Symbol not found: _memmem
Referenced from: ...../arm-linux-androideabi/bin/ld
Expected in: /usr/lib/libSystem.B.dylib</pre>
This problem was caused by building on Mac OS X 10.7, which produced binaries that were
not compatible with Mac OS 10.6.x and the NDK.
</li>
<li>Removed the {@code -x c++} options from the Clang++ standalone build script.
(<a href="http://code.google.com/p/android/issues/detail?id=39089">Issue 39089</a>)</li>
<li>Fixed issues using the {@code NDK_TOOLCHAIN_VERSION=clang3.1} option in Cygwin.
(<a href="http://code.google.com/p/android/issues/detail?id=39585">Issue 39585</a>)</li>
<li>Fixed the {@code make-standalone-toolchain.sh} script to allow generation of a
standalone toolchain using the Cygwin or MinGW environments. The resulting toolchain
can be used in Cygwin, MingGW or CMD.exe environments.
(<a href="http://code.google.com/p/android/issues/detail?id=39915">Issue 39915</a>,
<a href="http://code.google.com/p/android/issues/detail?id=39585">Issue 39585</a>)</li>
<li>Added missing {@code SL_IID_ANDROIDBUFFERQUEUESOURCE} option in android-14 builds for
ARM and X86.
(<a href="http://code.google.com/p/android/issues/detail?id=40625">Issue 40625</a>)</li>
<li>Fixed x86 CPU detection for the {@code ANDROID_CPU_X86_FEATURE_MOVBE} feature.
(<a href="http://code.google.com/p/android/issues/detail?id=39317">Issue 39317</a>)</li>
<li>Fixed an issue preventing the Standard Template Library (STL) from using C++
sources that do not have a {@code .cpp} file extension.</li>
<li>Fixed GCC 4.6 ARM internal compiler error <em>at reload1.c:1061</em>.
(<a href="http://code.google.com/p/android/issues/detail?id=20862">Issue 20862</a>)</li>
<li>Fixed GCC 4.4.3 ARM internal compiler error <em>at emit-rtl.c:1954</em>.
(<a href="http://code.google.com/p/android/issues/detail?id=22336">Issue 22336</a>)</li>
<li>Fixed GCC 4.4.3 ARM internal compiler error <em>at postreload.c:396</em>.
(<a href="http://code.google.com/p/android/issues/detail?id=22345">Issue 22345</a>)</li>
<li>Fixed problem with GCC 4.6/4.7 skipping lambda functions.
(<a href="http://code.google.com/p/android/issues/detail?id=35933">Issue 35933</a>)</li>
</ul>
